ABSTRACT These 13 treatment and care protocols are the cornerstone of the strategic actions that WHO has taken on as part of its contribution to universal access to HIV/AIDS prevention, treatment, care and support services as agreed on by the mem- ber states of the United Nations. They replace HIV/AIDS Treatment and Care: WHO protocols for CIS countries (2004) and have been specifically developed for the entire WHO European Region. Together, the 13 protocols represent a com- prehensive and evidence-based tool that offers clear and specific advice on diagnosing and managing a wide range of HIV/AIDS health related issues for adults, adolescents and children, including antiretroviral treatment, the management of opportunistic infections, tuberculosis, hepatitis, injecting drug use, sexual and reproductive health, the prevention of mother-to-child HIV transmission, immunizations, palliative care and post-exposure prophylaxis. As treatment and care for people living with HIV is a continuously evolving field, these protocols may be updated in the future; therefore the regional office encourages users to check for revisions at www.euro.who.int/aids.

The epidemic continues to spread, and in 2006 the Region recorded its second highest number of newly reported cases. Fortunately, with the introduction of highly active antiretroviral treatment (HAART) more than 10 years ago, the prognosis for most infected people in the Region is no longer death but chronic disease man- agement. As a result, when treatment and other health care issues are addressed judiciously, people with HIV can expect to live to old age. Universal access to HIV treatment and care, where available, has not only provided people living with HIV an almost normal life expectancy and comparable quality of life; it has also significantly reduced the risk of further transmission. High-quality HIV treatment and care must therefore address the issue of long-term care, as well as the complex interaction of various conditions and diseases that can simultaneously affect a person with HIV. The tremendous challenge that European health providers face is integration – integrating HIV treatment and care with mental health and substance use services, with treat- ment and care of major coinfections such as hepatitis and tuberculosis, with prevention and treatment of sexually transmitted infections, with other reproductive health services and with palliative care. These treatment and care protocols can help by providing an evidence-based package of interventions for chronic case management that is effective and patient-centred. The United Nations has charged WHO with leading the health sector response to the HIV/AIDS epidemic, particularly in promoting effective treatment and care. A major part of this role has been helping countries where treatment was just a dream a few years ago to scale up access to antiretroviral therapy. HAART is now available in every state of the European Region; the task at hand is to ensure that the best medicines in the correct dosages reach everyone in need. These 13 protocols form the cornerstone of strategic efforts by the WHO Regional Office for Europe to achieve universal access to HIV/AIDS prevention, treatment, care and support ser- vices. They replace HIV/AIDS treatment and care: WHO protocols for CIS countries (2004) and have been specifically developed for the entire European Region, based on current knowl- edge and the skills, technical capacity and health infrastructure found in the Region. Dr Nata Menabde Deputy Regional Director WHO Regional Office for Europe xiv Introduction HIV is a chronic infection with no known cure, and people living with HIV have to be followed medically for the rest of their lives. WHO promotes a comprehensive approach to the manage- ment of people living with HIV that addresses the individual’s full range of health-related needs, many of which may change during his or her lifetime. The underlying principle may be described as “treating the individual and not the disease”. The core component of this approach is the provision of antiretroviral treatment (ART). The optimal form of ART, known as highly active ART (HAART), combines three or more drugs, and it increases the length and quality of life for infected individuals while reducing the onward transmission of the virus. Evidence over the past decade from western Europe and other indus- trialized countries shows that what was once an almost universally fatal disease has become a manageable chronic condition, and that the medicines available today can ensure people living with HIV a life expectancy comparable to that of uninfected people. These treatment and care protocols for the WHO European Region are part of a global effort to achieve universal access to HIV prevention, treatment, care and support services by 2010, an effort led by the United Nations. The protocols provide normative guidance and technical tools that should strengthen health care providers’ ability to scale up HIV treatment and care services. These protocols have been specifically developed for clinicians and health care workers in- volved in diagnosing, treating, caring for and offering other health-related support and ser- vices to people living with HIV on a daily basis. They encourage collaboration and cooperation among health programmes. Together, the 13 protocols provide a comprehensive evidence-based tool offering clear, spe- cific advice on diagnosing and managing a wide range of HIV/AIDS health-related issues for adults, adolescents and children. Major topics include ART, the management of opportunistic infections, tuberculosis coinfection, hepatitis coinfection, injecting drug use, sexual and repro- ductive health, prevention of mother-to-child transmission, immunizations, palliative care and post-exposure prophylaxis. At times, the protocols diverge from the normative documents that WHO headquarters has developed for resource-limited settings around the world. In particular, we have taken into account specific epidemiological features of the HIV epidemic in the European Region that merit special attention – such as the significant role of injecting drug use, which has created a need for clinical guidance in managing hepatitis and other complex comorbidities, and the substantial population requiring the provision of not only ART but also specific mental health and substance use interventions. The fact that hundreds of thousands people with HIV in this Region are living long, active, productive lives has also created a need for detailed guidance on how to ensure not only basic survival but also good quality of life. For example, one of the ar- eas specifically addressed here is the sexual and reproductive health of people living with HIV, including reproduction and the ability to enjoy safe, fulfilling sexual lives. The organization of health systems in the European Region, their capacities and their techno- logical, institutional and human resources all differ from those of health systems in other WHO regions. These differences have dictated that we not only set minimum requirements for quality xv HIV treatment and care in these protocols, but that we also guide providers in the rational use of the complex technology that is widely available in the European Region Member States. We strongly believe that establishing standards that are optimal – and not merely minimal – is critical to an effective public health approach to HIV treatment and care. We have accordingly sought to incorporate the perspectives of people living with HIV and risk group members in developing these protocols, thereby enabling clinical providers to make rational choices that simultaneously ensure desirable population outcomes, such as reduced HIV-related morbidity and mortality, and tangible individual benefits. Considering the well-being of both the entire treatment population and the infected individual is a fundamental ethical obligation for medical professionals. Principles of medical ethics for- mulated since 1945 underline the responsibility of every physician to advocate, advance and protect the individual interest of each patient. As a citizen, the medical service provider should consider the greater societal good, but as a medical professional, he or she is obliged to serve the best interests of the individual. Cost-containment efforts, cost–effectiveness concerns and resource limitations are sometimes directly opposed to the dictates of medical professional eth- ics. In these protocols, we have attempted to reconcile these two often-divergent sets of priori- ties. As there is great diversity among the Member States in the European Region, we encourage individual ministries of health to adapt these protocols to meet their specific needs, or to use them as foundations for the development of their own national protocols. Finally, it should be remembered that HIV/AIDS treatment and care is a rapidly evolving field. We encourage users to check for protocol revisions at www.euro.who.int/aids, and to contribute to the further im- provement of these protocols by providing us with feedback on their technical usefulness.

The core component of treatment and care of PLHIV is provision of antiretroviral treatment (ART). Optimal ART increases the length and quality of life of HIV-infected patients, and reduces the onward transmission of the virus. WHO promotes a public health approach to ART (4), which promotes the rational selection and sequencing of different drug classes into first and second-line regimens with salvage options; simplified and standardised clinical management; and standardised record keeping in order to pre- serve therapeutic options, minimize drug toxicity and side-effects, maximize adherence and to sup- port the goals of ART. The goals of ART are: • clinical: prolongation of life and improvement of its quality; • immunological: quantitative and qualitative immunological reconstitution, in order to prevent the onset of opportunistic infections; • virological: maximum possible reduction of the viral load for the longest possible time, in order to halt the progression of disease and prevent and delay the development of drug resistance; • epidemiological: reduction, ideally the prevention of onward HIV transmission (5). WHO has produced a series of guidelines to support ART delivery in national programmes and by treatment implementers, which are available on the WHO website http://www.who.int/hiv/univer- salaccess2010/en/index.html. Particular reference is made in this protocol to the guidelines and recommendations for clinical and immunological staging and to ART guidelines for ART in adoles- cents and adults. Medical history, examination findings, exact history of ART, laboratory results, results of other medical procedures and social circumstances need to be documented for the entire treatment period, which may be years or even decades long. Such records are crucial for the individual patient as well as for retrospective analysis (for example, in endoscopic procedures, CT scanning, advanced microbiologic testing or viral load (VL) testing). For such purposes, an electronic record-keeping system is advisable, especially at the clinical level. Confidentiality of medical information should be ensured. Optimal HIV-related treatment and care should be delivered by clinical teams. The core clinical team providing basic medical case-management of a patient should ideally consist of a physician (often an infectious disease specialist), a nurse and a social worker or a non-medical service pro- vider. Each of the team members has distinctive roles in providing treatment and care, and their services should be complementary. A network of other specialists and self-help groups should be available in supporting PLHIV (6).  HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION II. Management of patients with HIV Proper management of patients living with HIV is a comprehensive lifelong process focused on the patient’s needs. It should include: • initial HIV testing and confirmation of the result; • appropriate counselling during the process of identifying HIV infection; • clinical evaluation; • patient counselling; • monitoring patient health; • initiating ART and its maintenance; • prevention and treatment of opportunistic infections (OIs), other coinfections and comorbidi- ties; • psychological support; • adherence support; and • referrals to provide continuity of care. Clinical evaluation of patients should include testing and counselling for health maintenance issues related to HIV as well as to other conditions that may interact with the management of HIV infec- tion, especially potential interactions with ART. 1. Initial patient evaluation The initial evaluation of a patient aims at determining the full status of his/her HIV infection, to develop a basis for further clinical management and for referral to non-medical services as appropriate. Initial patient evaluation should include: • confirmation of HIV infection status with potential time of infection established, if possible; • a detailed personal, family and medical history; • physical examination; • laboratory and other examinations; • specialist examinations, as appropriate; and • clinical and immunological staging. 1.1. Personal, family and medical history Patients newly diagnosed with HIV infection or patients who are transferred in, having had their long-term care and ART being initiated elsewhere, should provide a complete history before physi- cal examination (7). See Table 1. PATIENT EVALUATION AND ANTIRETROVIRAL TREATMENT FOR ADULTS AND ADOLESCENTS Table 1.

HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 1.2. Physical examination The physical examination should document presenting symptoms and signs and reproducible re- sults so that other physicians can determine changes in status. A standardized history and examina- tion questionnaire is preferable; see Table 2. Table 2. Initial physical examination General appearance: • height and weight • body morphology (lipodystrophy) • Karnowsky index or other standardized scale for general fitness Vital signs: • blood pressure • temperature • pulse • respiratory rate Lymph nodes Skin (entire body): • in particular, assess for ° active or former herpes zoster ° liver disease ° Kaposi sarcoma ° seborrhoeic dermatitis ° injection sites in injecting drug users (IDUs)The documentation of skin disorders such as discoloured brown or dark patches is best made with photos; other pos- sibilities include drawing the area of a patch on transparent foil, to be able to compare in future in examinations. Oro-pharynx: • oral health and dental status • signs for: ° oral candidiasis ° oral hairy leukoplakia ° primary syphilis Thorax and lungs: • signs (breathing, cough, dyspnoea) • form of thorax • control for risk of emphysema Mamma examination (in female and male patients) to control for risk of carcinoma Cardiac examination for baseline information when there may be higher risk for cardiovascular complications with ART (9, 10) or risk for endocarditis in IDUs Abdominal examination (for baseline information for ART side-effects, especially in cases of chronic hepatitis, alcohol toxicity and cirrhosis): • consistency, size and shape of liver and spleen • bowel movement • tenderness • rigidity • nausea, vomiting, disphagia Genital and anal region examination: • signs for: ° herpes simplex ° cytomegalovirus (CMV) ° syphilis ° Human papilloma virus (HPV), (condylomata acuminatae, anal carcinoma) (11), other STIs ° erectile dysfunction Legs (movement, mobility, lipodystrophy) to provide baseline information for ART side-effects Neurological status (also signs of neuropathy) Mental status Eye and ear functions PATIENT EVALUATION AND ANTIRETROVIRAL TREATMENT FOR ADULTS AND ADOLESCENTS 1.3. Laboratory and other examinations Table 3. Laboratory testing HIV-related testing: • HIV serological testing (typically an enzyme-linked immunosorbent assay (ELISA) or rapid blood test), fol- lowed by confirmatory test (typically western blot) (12) • CD4 cell count to determine the severity of immunodeficiency; in pregnant women CD4 % (13, 14) • viral load testing by polymerase chain reaction (PCR), to determine level of viral replicationa Other infectious disease testing: Routine testing: • venereal disease research laboratory (VDRL) test for syphilis • serological tests for hepatitis C and B viruses (HCV and HBV) – i.e. HCV antibodies and hepatitis B surface antigen (HBsAg)b • toxoplasma immunoglobulin G (IgG) serological test and information about risk of infection if negative If indicated: • vaginal, penile or anal (as appropriate) swab for gonorrhoea and Chlamydia trachomatis • Cryptococcus antigen titre when CD4 cell count is <200/mm3 with clinical signs of cryptococcosis • CMV antigenaemia (pp65 early antigen), when CD4 cell count is <100/mm3.c General laboratory testing: • electrolytes (sodium, potassium) • liver function (alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase) • bilirubin • renal function (blood urea nitrogen (BUN), creatinine) • lactate dehydrogenase (LDH) (general turnover of cells in lymphomas, signs of pulmonary infections, myocar- dial infarction, muscle damage, etc.) • quick (international normalized ratio (INR) test or prothrombine time) • full blood count with differential and platelets • pregnancy test before initiating ART If available: • fasting glucose • cholesterol (high-density lipoprotein (HDL), very-low-density lipoprotein (VLDL)) • triglycerides • lipase • C-reactive protein (CRP) • thyroid-stimulating hormone (TSH) Table 4. Other examinations • tuberculin skin test for those with no TB symptoms or no known TB exposurea • sputum-smear microscopy and chest X-ray if signs and symptoms of active TB are presenta • ECG – optional (might be useful as a baseline for comparison due to greater risk for cardiovascular disease with ART) (15) Other examinations may be necessary, depending on individual comorbidities, for example, in HCV/HIV or HBV/HIV coinfection, abdominal ultrasound to assess lymph nodes, size and shape of liver and spleen; or in presence of clinical signs of gastrointestinal (GI) tract disease, endoscopy of the upper and lower GI tract. Endoscopic findings should be documented with photos. a Performance of tests by the same laboratory is preferable to rule out technical discrepancies. b For further information on testing of hepatitis, please refer to Protocols 6 and 7, Management of hepatitis C and HIV coinfec- tion and Management of hepatitis B and HIV coinfection. c Very early detection of CMV infection is possible, and is a good marker for treatment response in CMV infection. a For further information please refer to Protocol 4, Management of tuberculosis and HIV coinfection. 10 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Table . Specialist consultations if required • neurological examination (for peripheral polyneuropathy) • ophthalmological examination (useful to repeat every three months for CMV retinitis when CD4 count is <100/mm3) • gynaecological examination including a Pap smear every six months (for human papillomavirus-mediated (HPV- mediated) carcinoma)a • other specialist consultations as needed 2. Counselling on issues related to living with HIV Patient counselling is an essential component of patient management strategy and patient-health care provider relationships. It should start with the assessment and discussion of the patient’s social conditions, which may be predictors of cooperation during treatment. These include: • partnership status and quality • employment status, type of work and conditions • people who are informed and should be informed of the HIV status • people with whom health care workers can discuss the patient’s health-related matters • familial relationships • availability of safe refrigerated storage for medications • lifestyle factors that might interfere with treatment (16–18). Health care providers who counsel PLHIV should ensure that certain information is discussed and understood by the patient. • Risk reduction (safe sex, injecting practices, etc.) must be explained, including the danger that unprotected sex with HIV-positive partners could lead to super-infection with another HIV strain and possible resistance to antiretrovirals (ARVs) (19). • Importance of disclosure to sexual partner(s), friends and family members for a few reasons: ° obtaining psychological and treatment support ° prevention of HIV transmission ° testing of sexual partner(s). • Availability of treatment, its benefits, preparedness to it, long-term consequences and impor- tance of adherence should be discussed with every patient. • Patients need to be informed about signs of possible OIs, and encouraged to have further evalu- ation. For further information, see Protocol 2, Management of opportunistic infections and gen- eral symptoms of HIV/AIDS. • The importance of stopping illicit drug use needs to be discussed with users. If a patient is un- able or unwilling to stop, the merits of harm-reduction measures should be discussed, including the merits of reducing drug use; not injecting; not sharing needles, syringes or other injecting paraphernalia; and drug dependence therapy (such as OST). For more information, please refer to Protocol 5, HIV/AIDS treatment and care for injecting drug users. • Prevention of other infections should be discussed. Please refer to section 3 below. • Based on the assessment of social conditions, healthy daily habits – sleep, nutrition, exercise – should be encouraged. • Patients about to initiate ART should be counselled on: ° adherence (see section II.4.3 below) ° possible antiretroviral (ARV) toxicity (see section II.5.5 below) a There is no hard evidence to recommend routine rectal PAP smears at the time of writing this protocol. For more information please refer to Protocol 9, Support for sexual and reproductive health of people living with HIV. 11 PATIENT EVALUATION AND ANTIRETROVIRAL TREATMENT FOR ADULTS AND ADOLESCENTS ° drug interactions (see section II.5.6 below) ° reliable contraception when the ARV regimen will contain efavirenz (EFV) (for further in- formation refer to Protocol 9, Support for sexual and reproductive health in people living with HIV) ° patient understanding of treatment process and related to it issues should be ensured by the health care provider. • Patients should also be informed about legal responsibilities (if applicable) and their rights and be referred to other appropriate services. • Patients should be informed of issues related to immunization (including travel) and occupa- tional risks. 3. Prevention of opportunistic and other infections • Prevention of active tuberculosis is among the first priorities. For more information on manage- ment of TB/HIV coinfected patients and prevention of active TB please see Protocol 4, Manage- ment of tuberculosis and HIV coinfection. • As HBV/HIV and HCV/HIV coinfections are common and present further medical difficulties, their prevention must be emphasized. It is equally important to advise on reducing the risk of liver-related harm and preventing mother-to-child transmission (MTCT).2 • PLHIV should be immunized against hepatitis B and A and influenza. For further information, please refer to Protocol 12, Immunization of people living with HIV and people at risk for HIV. • Every patient with a CD4 cell count less than 200 cells/mm3 should be given prophylaxis against certain opportunistic infections, in particular Pneumocystis jirovecii pneumonia (PCP) and other infections. Co-trimoxazole should be given until the CD4 cell count is >200/ mm3 for more than three months after initiating ART. For more information please refer to Protocol 2, Management of opportunistic infections and general symptoms of HIV/AIDS. • In case of negative toxoplasma serology, the transmission route and ways to prevent infection should be explained (including risks associated with pets). For futher information see Protocol 2, Management of opportunistic infections and general symptoms of HIV/AIDS. 4. Antiretroviral treatment 4.1. Initiation of ART The best point at which to start ART is under discussion (20). A review of several cohort studies and guidelines shows a widespread view that clinical staging (stage 3 or 4) and CD4 counts are the best primary markers and viral load the secondary marker for this decision (21–31). Prior to starting ART, support to ensure adherence should be initiated; see section II.4.3 below. 2 For further information see Protocol 6, Management of hepatitis C and HIV coinfection, Protocol 7, Management of hepatitis B and HIV coinfection, Protocol 8, Prevention of hepatitis A, B, C and other hepatotoxic factors in people living with HIV, and Protocol 10, Prevention of HIV transmission from HIV-infected mothers to their infants. 12 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 4.1.1. Clinical and immunological considerations WHO recommends initiation of ART using clinical and immunological criteria as per Table 6. Table . Recommendations for initiating ART in PLHIV WHO clinical stagea CD4 cell count Recommendation 1 <200/mm3 Treat 200–350/mm3 Consider treatmentb 2 <200/mm3 Treat 200–350/mm3 Consider treatmentb 3 200–350/mm3 Treat 4 Regardless of CD4 count Treat The decision to initiate ART should be based on two different CD4 counts, ideally at least 7 days apart because of variability in the CD4 count itself and to rule out laboratory mistakes and other variances (for example, concurrent illnesses). In case of a concurrent acute illness, CD4 cell count should be repeated only after the illness is cured. Therapy should not however be delayed if a pa- tient is unwell or if the second count cannot readily be performed. If the CD4 count is not available, the decision to initiate ART can still be made on clinical grounds alone – with clinical stage 3 or 4 illness. Baseline CD4 count at the onset of ART (ideally determined when the patient is free from any active major opportunistic infection) is a critical value in determining prognosis, response to ART and for monitoring the subsequent immunological response to ART. 4.1.2. Considerations for viral load Viral load is associated with loss of CD4 cells. Though on its own it is not a marker for initiating ART, in case of viral load >100 000 copies/ml (this can go as high as 1 million copies), the probabil- ity of rapid CD4 cell count decline is very high. Therefore, it is recommended to consider initiation of ART at CD4 cell count of 350/mm3 if the viral load is higher than 100 000 copies/ml. While viral load testing is more expensive and may be less accessible, it is important to have a baseline viral load if at all possible, as this value is relevant for monitoring ART. The absence of viral load data should not be a criterion for delaying the start of treatment, or used as a reason for treatment exclusion. 4.1.3. Considerations for drug resistance test Prevalence of HIV drug resistance varies in different countries and is linked to several factors, including the duration of ART availability, history of treatment (mono- and dual therapy) and ad- herence. In western Europe, multicentric studies showed a 10% overall prevalence of resistance in newly diagnosed HIV-infected individuals between 1996 and 2002 (32). A study of 40 cities in the United States revealed a resistance rate of 14% (33). The highest results from these studies were 26% in Spain (34) and 19% in San Francisco (35). In countries with a short or no history of ART, risk of HIV drug resistant virus transmission is significantly lower, and the first-line highly ac- tive antiretroviral treatment (HAART) regimen recommended below (section II.4.2) is effective for treatment of naïve patients. It is important to have population-based HIV drug resistance strategies in place to monitor for the appearance and spread of HIV drug resistance; and to act on the early warning indicators for drug resistance emergence in order to minimize its appearance and onward spread. a See Annex 2 for a description of the clinical stages. b When the CD4 count is around 350 cells/mm3, begin discussions with the patient on the advancing need for initiating ART and on preparations for starting. 13 PATIENT EVALUATION AND ANTIRETROVIRAL TREATMENT FOR ADULTS AND ADOLESCENTS WHO does not recommend individual drug resistance testing prior to initiation of ART in settings where only one first-line regimen is provided in the public sector because any results will not in- fluence ART. Instead, sentinel surveys that demonstrate resistance at population level above the threshold of 5% (36, 37) should be taken into consideration in adapting national recommendations for first-line ART. Refer to Annex 3 for additional information on resistance testing. Where re- sources permit, and the public sector provides more than one first-line regimen, then drug resistance testing at baseline may help determine the choice of optimal ART; cost and availability will likely limit the widespread use of this in many settings (38–40). 4.2. First-line HAART regimen It is recommended that two nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs) and one non-nucleoside reverse transcriptase inhibitor (NNRTI) be combined in the first-line HAART regi- men. Table . Recommended first-line HAART ARV drug classes HAART regimens 2 NRTIs + 1 NNRTI ZDV + 3TC + (EFV a or NVP) or TDF + FTC + (EFV a or NVP) or ABC + 3TC + (EFV a or NVP) (For recommended dosages, please refer to Annex 4.) 4.2.1. Considerations for NRTI component • The “backbone” of first-line ART is a combination of two NRTIs. One should be lamivudine (3TC) or emtricitabine (FTC); FTC is considered an equivalent drug to 3TC in both efficacy and toxicity (41). The second is most often the thymidine analogue zidovudine (ZDV also known as AZT). A large body of data and provider experience is available for ZDV, as it was the first known ARV drug. • Stavudine (d4T) is another thymidine analogue. It is available in several fixed-dose combina- tions (FDCs), is cheaper than ZDV and consequently widely used in many countries. However, it has a poor toxicity profile and recent studies have shown a higher rate of long term side-ef- fects with d4T (42–49). Many national and international recommendations are moving away from recommending it for initial therapy. It is increasingly being reserved as an alternative for ZDV (a within class substitution) when ZDV has to be substituted or changed for side effects or toxicity. The lower dose 30 mg is now recommended for all weights to reduce long-term toxic- ity. • Other possible non-thymidine analogues for first-line are tenofovir (TDF) or abacavir (ABC) in combination with 3TC or FTC. Recently, one study has shown a slight superiority of TDF/FTC over ZDV/3TC when used in combination with EFV (42), probably due to a lower rate of side- effects in the TDF arm. Further studies are needed. It should be noted that ABC has a risk of dangerous hypersensitivity syndrome; and, TDF can cause renal damage, so pre-screening for renal function is usually recommended. • The advantage of TDF and ABC is their resistance profile, which potentially allows more NRTI combinations to support second-line protease inhibitors (PIs). The disadvantages are cost, avail- a EFV is highlighted as the preferred NNRTI. 14 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION ability and licensing, and the relative lack of programmatic experience and effectiveness data, which is less comprehensive than the data for the thymidine analogues (43). • NRTIs are available (or are likely soon to be prequalified and available) in the following FDCs, or one-pill formulations from originator and generic manufacturers: ° ZDV + 3TC ° TDF + FTC, TDF + 3TC ° ABC + 3TC ° d4T + 3TC • An additional advantage of TDF/FTC and ABC/3TC is the availability of a once-daily regi- men. Other NRTIs and combinations are not recommended for first-line ART (44). Certain rules pertain to the use of NRTIs. • Do not combine “d-drugs” (ddI (didanosine), d4T). • Do not give single d-drugs with pre-existing polyneuropathy. • Do not combine ZDV and d4T. • Do not combine 3TC and FTC. 4.2.2. Considerations for NNRTI component • There are two NNRTIs, EFV and nevirapine (NVP), which are available and recommended for first-line ART. The effectiveness of NVP is comparable to that of EFV (50). Both have impor- tant toxicities and side-effects which limit how they can widely be used. • The best available data are for the regimen of ZDV + 3TC + EFV (51–53). This three-pill com- bination is given in two doses per day. It is fast acting, the viral load falls rapidly in the first two weeks with EFV, the increase of CD4 count is comparable to other regimens and problems are limited. • EFV should be avoided in patients with a history of severe psychiatric illness, in women of childbearing age who do not use effective contraceptives, and during the first trimester of preg- nancy. NVP is an alternative option for these cases. • NVP can cause severe hepatic toxicity which seems to be related to the level of immunosup- pression (54) so its use is limited to female patients with CD4 count <250 cells/mm3 and males with CD4 count <400 cells/mm3. CD4 counts higher than these are associated with more risk of hepatic toxicity. • NVP needs to be dose-escalated. There is a recommended 14-day lead-in period with 200 mg NVP once daily (OD) when starting this regimen, for better tolerance. After 14 days, the dosage should be increased to the standard regular 200 mg twice daily (BID). • EFV is usually preferred when the patient is being co-treated for TB with rifampicin (see Proto- col 4, Management of tuberculosis and HIV coinfection for further information). • The combination of two NNRTIs with one NRTI is not recommended (55). 4.2.3. Alternative first line HAART regimens • Triple NRTI-based first-line regimens such as ZDV+3TC+ABC and ZDV+3TC+TDF can be recommended in specific circumstances where NNRTI is contraindicated or too complex to manage and have the advantage that they still preserve the PI class for second-line ART. These regimens can be used in the following circumstances: ° intolerance or resistance to NNRTIs; ° psychiatric disorders; ° pre-existing liver disease – an increase of the ALT level by more than 3–5 fold–and estab-lished cirrhosis; ° coinfection with HBV or HCV; ° HIV-2 infection due to intrinsic resistance to NNRTI class; and ° cotreatment of TB in women of child-bearing age and where adequate contraception cannot be guaranteed, and when NVP and boosted PIs cannot be used. 1 PATIENT EVALUATION AND ANTIRETROVIRAL TREATMENT FOR ADULTS AND ADOLESCENTS • ZDV+3TC+ABC has short-term inferior virological efficacy at least in patients with high ini- tial viral loads but comparative immunological efficacy to ZDV+3TC+EFV regimen (51, 56). ZDV+3TC+TDF is a promising regimen but there are limited data to date (see the following Protocols: 4, Management of tuberculosis and HIV coinfection; 6, Management of hepatitis C and HIV coinfection; and 7, Management of hepatitis B and HIV coinfection). • Other triple NRTI-based regimens, such as ZDV+TDF+ABC or TDF+3TC+ddI have unaccept- ably high virological failure rates and high incidence of the K65R mutation (57, 58) and should not be used. • Boosted PIs are usually reserved for second-line ART. They can exceptionally be used as part of first-line ART in combination with two NRTIs when triple NRTI regimen is not available or deemed inappropriate or when there are contraindications for NNRTIs (i.e. neither EFV nor NVP can be prescribed) including: ° psychiatric disorders; ° an increase of the ALT level by more than 3–5 fold; ° cirrhosis; ° pregnancy with CD4 count of 250–350 cells/mm3, particularly in the 1st trimester of preg-nancy (as EFV is contraindicated); ° HIV-2 infection due to intrinsic resistance to NNRTI class; and• If a first-line ART regimen containing a PI fails, there are very limited options for subsequent regimens at least within a public health approach and within the public sector in many countries. A failing PI regimen has, in consequence, more resistance patterns than a failing NNRTI regi- men (point mutation in NNRTI class). In general therefore, it is recommended that PIs be left to second-line ART. 4.3. Adherence to ART Optimal treatment benefits require strict adherence to ART. It is well recognized that when adher- ence is high, there is a dramatic reduction in HIV-associated morbidity and mortality (59), whereas low adherence leads to rapid development of drug resistance (60). Effective adherence levels have not been fully defined for ART (there being differences between a number of regimens), but levels lower than 95% have been associated with poor virological and immunological response, while levels of 100% seem to achieve even greater benefit than 95% (61, 62). The most recent data show a correlation between drug resistance in various classes of ARVs and adherence (63). Low or insufficient adherence has consequences for patients, public health and national econo- mies. • Patients are in danger of developing significant viral resistance, treatment failure and disease progression (64, 65). Changing to a new regimen after treatment failure results, in most cases, in more difficult adherence (more pills, side-effects, dietary restrictions, toxicity and dosing complexity). • The increase in resistant viruses is likely to result in their transmission to newly infected indi- viduals. Data from the United States (66) and Europe (67) suggest that such primary resistance is increasing, and that acquired resistance has a negative effect on ART response. • Economically, the presence of resistant strains will result in increased use of second-line and salvage regimens, which are in general more expensive than first-line regimens. • Low adherence also means a higher risk of disease progression, resulting in higher costs for treating opportunistic infections (68). 1 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 4.3.1. Barriers to high adherence and counteracting strategies Health care workers should identify possible factors which might lead to poor adherence to treat- ment and address it accordingly. 4.3.1.1. Patient factors and supportive methods The role of patients themselves is fundamental. One cannot predict patients’ adherence potential. Studies investigating the role of gender, race, age, mode of transmission and educational level as in- dicators of adherence have produced inconsistent results (69). Individual adherence rates also vary over time (70). Most PLHIV under treatment will exhibit low adherence at some time. Barriers to adherence include: • drug and alcohol use (may impair routine use of medication) • poor diet due to poverty or due to other reasons • religious beliefs (71) • fear of disclosing HIV status through routine medications • psychiatric conditions (72) • fear of side-effects and doubts about the necessity of medication (73). Methods to support adherence include: • education on the need for ART • addressing patient misconceptions promptly • regular evaluation of patient commitment to ART • peer intervention (groups, friends, patient supporters) • regular assessment of mental health problems • assessing behavioral skills needed for adherence3 • contacting specialized social care services and other institutions. 4.3.1.2. Provider factors Health care providers should clearly understand adherence and its role in resistance development when providing adherence support. Professionals working in the area of HIV/AIDS require con- tinuous education in adherence issues. There are several strategies that health care workers should employ to increase adherence: • Every HIV treatment centre should have a written and regularly reviewed adherence strategy. • Health professionals need to be engaged in adherence support programmes (74). • Exploring patient preferences for involvement may act as a catalyst to adherence. • Adherence services should be offered to all patients, taking into account the varying degrees of adherence that all patients show over the course of treatment. • Adherence support should be continued for second-line and salvage regimens. Treatment failure is a key point for reinforcing adherence and support interventions (75). • As high adherence is a process and not a single event (76), support must be offered when start- ing ART, changing ART and as a routine follow-up. • Providers must ensure that patients have sufficient understanding of HIV, the relationship be- tween adherence and resistance, the requirements of their regimen and potential side-effects. Verbal information should be supported by written information. • Pill diaries, pill charts, medication containers, electronic reminders, and enlistment of family and friends as reminders can all be recommended by health care providers (77). • Adherence to ART is improved where patients view their relationship with their doctor and other health care providers positively (78). 3 These can be augmented by contacting people who can help (nurses, pharmacy, family), and by using timetables, pill boxes with clocks, pill-taking routines, strategies for travel and managing disclosure or discovery by others. 1 PATIENT EVALUATION AND ANTIRETROVIRAL TREATMENT FOR ADULTS AND ADOLESCENTS • Early follow-up should occur two days after initiating or changing a regimen, to evaluate wheth- er the patient needs more information or has unregistered problems. • The partnership between clinics and community-based organizations can improve the uptake of information, especially among hard-to-reach populations and some ethnic groups. 4.3.1.3. Regimen factors and strategies • Dosing more than two times a day is associated with lower adherence levels (79), while there is probably no adherence difference between one or two daily doses (80). In regimens with single or double daily dosing, more of the doses are taken at a time. Taking the dose later than prescribed has been associated with treatment failure in multivariate analysis (81). • A low pill burden is associated with the likelihood of having a viral load below 50 copies/ml after 48 weeks (80). • Adherence levels are not correlated with any ARV class. However, conflicting dietary rules for different drugs can be a problem (82). • Harmful drug interactions and side-effects can influence adherence. Doses can be missed due to vomiting or diarrhoea, and fatigue can cause patients to sleep past doses (83). Methods to support adherence include: • evaluating lifestyle factors like eating, sleeping and working patterns and adjusting the regimen accordingly; • assessing individual preferences for regimen characteristics such as pill size, formulation, bur- den, dietary restrictions, etc.; • showing patients the pills prior to regimen selection; • education about side-effects, prompt palliation of them and information about support; • dispensing medication in small amounts at frequent intervals, which can facilitate: ° opportunities to address adherence problems before they lead to resistance; ° limiting treatment disruptions and misuse;• utilization of once-daily options and FDCs, which can lower the pill burden and be beneficial early in treatment; and • directly observed treatment (DOT), particularly in hospitals. 4.4. ART success and failure All patients should be regularly monitored by skilled clinicians. Ideally all should have access to both immunological and virological tests. Successful ART can be defined by clinical, immunologi- cal or virological criteria (see Table 8). Table . Criteria for treatment success Virological Immunological Clinical Marker Viral Load CD4 cell count Clinical stage Timea 24 weeks 48 weeks 24–48 weeks By 12 weeks of treatment initiation should be asymptomatic or have few symptoms Suggested rangesa <400 copies/ml <50 copies/ml Increase from baseline by at least 50-100 cells/mm3 Stage 1 or 2b Failure of first-line ART can be defined and identified in three different ways: clinically, immuno- logically and virologically. The three may reflect different aspects of failure. Further, it is proving difficult in the absence of good clinical end-point data on the subsequent durability of second-line responses, to know which is the best indicator of when to switch and what value or level should be used. There are differing views about whether a patient with a “failing” regimen, regardless of a Time and suggested ranges should not be seen as absolute and strict numbers. b Please see section II.5.3 below for more information on immune reconstitution inflammatory syndrome (IRIS). 1 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION criterion used, should switch to second-line ART, and when to do so. There is no clear consensus globally on the definition of treatment failure. Currently, different biological end-points are used to represent virological, immunological and clinical failure in different settings. 4.4.1. Virological response • VL is the earliest indicator of treatment success or failure, followed by CD4 cell count approxi- mately a month later. In rare cases, a paradoxical reaction of virological response and immuno- logical failure occurs; consequently, VL should be seen in combination with CD4 cell count. • Failure to decrease viral load to <400 copies/ml by week 24 of treatment or <50 copies/ml by week 48 means incomplete virological response. • When the viral load has already decreased to an undetectable level, but two measurements are >400–1000 copies/ml in 4 to 8 weeks, it means there is a risk of virological failure (84).3 • “Blips” are slight elevations of viral load, from under the testing threshold to around 50–200 copies/ml. They may happen without the development of resistant virus strains (laboratory er- rors), but should be an indicator for a discussion of adherence (86). In this situation, therapeutic drug monitoring (TDM) may also be helpful, if available. Any blip should be controlled within four weeks. • If no reason is found for virological failure (poor adherence, suboptimal drug levels, drug–drug interactions, etc.), a second-line regimen should be discussed. 4.4.2. Immunological response • CD4 cell count response on its own can be used as an indicator of treatment failure or success. • On average, a CD4 cell increase of about 150 cells/mm³ occurs in the first year in treatment-na- ive patients (87, 88). Failure to increase CD4 cell count more than 50 cells/mm³ during the first year of ART is considered immunological failure. • If the CD4 cell count does not increase for six months, adherence to treatment should be reas- sessed and ensured. 4.4.3. Clinical response • Patients will usually reverse their clinical stage and become asymptomatic (stage 1) or have minimal or minor HIV-related signs and symptoms (stage 2). • Some stage 3 or 4 OIs can recur and the prognostic significance of oral and oesophageal candida in particular is not always clear-cut. • Usually however, presentation of a new or recurrent stage 3 or 4 event (OI or other HIV-related illness) after initiation of ART is an indicator of clinical failure. 4.4.4. Dissociated virological and immunological responses Despite the persistence of low but detectable viremia (VL suppressed to less than the natural set point), CD4 cell count may remain stable or even increase in some patients taking HAART (89–91). In a large intercohort analysis even in those people who had experienced 3-class virological failure and continue to take HAART, viremia less than 10 000 copies/ml or suppression of at least 1.5 log copies/ml less than the pretherapy value, was not associated with a decline in CD4 cell count (92, 93). 4 WHO headquarters notes that the optimal viral load value at which ART should be switched has not been defined. However, values of more than 10 000 copies/ml have been associated with subsequent clinical progression and appreciable CD4 cell count decline. In resource-limited settings, WHO, at the global level, has provisionally opted for 10 000 copies/ml, as an in- terim recommendation for switching to second-line HAART, if the VL indicator is used as a criterion (85). 1 PATIENT EVALUATION AND ANTIRETROVIRAL TREATMENT FOR ADULTS AND ADOLESCENTS 4.. Second-line HAART regimen • When failure of the first-line regimen has been identified, it is recommended that all drugs are changed and then the patient switches to second-line treatment. • Second-line ART is the next regimen used in sequence immediately after first-line ART has failed. The PI class is reserved for second-line use. Ideally, ritonavir-boosted PIs are recom- mended, supported by two agents from the NRTI class. See Table 9 for second-line ARV regi- mens. Table . Recommended second-line HAART for adults and adolescents First-line HAART regimens Second-line HAART regimens after treatment failure ZDV + 3TC + (EFV or NVP) LPV/ra (or ATV/r, SQV/r, FPV/r, IDV/r) + ddI + ABC or LPV/ra (or ATV/r, SQV/r, FPV/r, IDV/r) + TDF + ABC or LPV/ra (or ATV/r, SQV/r, FPV/r, IDV/r) + TDF + (ZDV + 3TC) b TDF + FTC + (EFV or NVP) LPV/ra (or ATV/r, SQV/r, FPV/r, IDV/r) + ddI + ABC or LPV/ra (or ATV/r, SQV/r, FPV/r, IDV/r) + ddI + ZDV ABC + 3TC + (EFV or NVP) LPV/ra (or ATV/r, SQV/r, FPV/r, IDV/r) + ddI + ZDV or LPV/ra (or ATV/r, SQV/r, FPV/r, IDV/r) + ZDV + TDF (+ 3TC) b (For recommended dosages of ARVs, please refer to Annex 4.) 4..1. Considerations for NRTI component • Minimum changes for a second-line regimen are two new NRTI drugs. Never change only one drug in cases of suspected resistance. • If the first-line ART included ZDV + 3TC, then ABC in combination with ddI (or TDF with dose-adjusted ddI and close monitoring) may be an option (94). • Patients who began with TDF or ABC may now benefit from ZDV (95), due to the higher like- lihood of resistance. For instance, the K65R mutation promoted by TDF and ABC increases susceptibility to ZDV (96, 97). • 3TC is also useful in cases of 3TC resistance, as the regularly acquired 184V mutation reduces viral fitness and also increases susceptibility to ZDV (96). 4..2. Considerations for PI component • With a first-line regimen containing a NNRTI, second-line ART should include a PI. • In the PI class, the majority of drugs are boosted with a low dose of RTV, itself a PI, 100 mg BID – except nelfinavir (NFV), which is boosted not chemically but with food. The means of boosting is ritonavir’s inhibition of the cytochrome P450 (CYP) 3A4 isoenzyme. Subsequently, the drug levels of the main PIs (except NFV) are increased (98). RTV is used only for boosting other PIs and is not effective as a stand-alone ARV. • The differences among the PIs lie in the number of mutations needed to develop resistance and in the profile of their side-effects. • One of the highest genetic barriers for resistance is documented for LPV/r (99). • The resistance profiles of ritonavir-boosted atazanavir (ATV/r), fosamprenavir (FPV/r), indina- vir (IDV/r) and SQV/r show slight differences that have little or no clinical impact. a LPV/r is listed as the preferred RTV-boosted PI in this table, but other boosted PIs can be substituted, based on individual pro- gramme priorities. ATV/r, SQV/r, FPV/r and IDV/r are all possibilities. In the absence of a cold chain, NFV can be employed as the PI component, but it is considered less potent than an RTV-boosted PI. b ZDV + 3TC are listed here for strategic use since resistance to both is predicted following failure of the listed first-line regi- men. ZDV may prevent or delay the emergence of the K65R mutation; 3TC will maintain the M184V mutation, which may decrease viral replicative capacity as well as induce some degree of viral resensitization to ZDV. It must be stressed that the clinical efficacy of this strategy has not been proven. 20 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION • NFV seems to be inferior to the other PIs, but it is well documented in pregnant women. In case of failure, the D30N mutation is usually selected; it does not encode for cross-resistance for other PIs (100, 101). • LPV/r is the PI of choice due to its well-documented potency (102), availability as a FDC and relatively low pill burden and good tolerance. A new tablet formulation of LPV/r has been ap- proved in Europe requiring two pills BID and no refrigeration (103). • Recent studies (104, 105) showed similar efficacy of SQV/r and FPV/r to LPV/r, but in ARV naive patients. The pro-drug formulation of amprenavir (APV) in the form of FPV, the once- daily PI ATV and the new formulation of SQV (500 mg tablets) have not been directly tested against LPV/r. Therefore, only indirect data are available. Further studies with head to head comparisons among boosted PIs in ARV experienced individuals are needed. • Possible side effects, comorbidities, drug interactions and individual preferences should influ- ence the choice of PI. • If first-line ART regimens containing PIs fail, the choice of a second-line regimen is mainly based on resistance profiles. If resistance profiles are not available, then resistance to the PIs contained in the first-line regimen must be assumed to be the cause of the regimen’s failure (see section II.4.4 above for success and failure criteria). • Possible options in the event a first-line regimen with a PI fails: ° ZDV + 3TC + PI/r → ABC + ddI + NNRTI ° or one of the salvage options (see section II.4.6 below). 4.. Salvage regimens In case of confirmed second-line ARV treatment failure (using virological, immunological or clini- cal criteria), a salvage regimen should be considered. Salvage regimens are combinations of drugs that will probably work even against viruses that are partly drug resistant. Every regimen after sec- ond-line treatment is complicated and requires a high level of ART knowledge and skill on the part of the healthcare provider. Performing a resistance test in these circumstances is highly desirable. It is at times better to wait several months before initiating salvage treatment, although this strategy can be dangerous, particularly if the CD4 cell count is low. • If possible two effective drugs should be added, for example the fusion inhibitor enfuviztide (ENF) (106), which is administered twice daily with subcutaneous application, and the new boosted PIs TPV/r (107, 108) or boosted darunavir (DRV/r) (108–112). • The genetic barrier of TPV/r seems to be even higher than that of LPV/r, and data show its effi- cacy to be comparable or better than the latter’s (113). This PI is presently used only for salvage regimens. • Another option is a combination of two PIs (114–117), except boosted tipranavir (TPV/r), which is not to be combined with any other PIs. (For recommended dosages, please refer to Annex 4.) 4.. Structured treatment interruption Most ART providers are opposed to planned interruptions, but there are conditions that may justify them. For example, constant CD4 count >500 cells/mm3 with completely suppressed virus for years may offer such an opportunity. Although it is not necessary to interrupt, it is better to do so than to face poor adherence followed by the development of resistant strains. During structured treat- ment interruption, the CD4 cell count normally falls rapidly to pre-ART levels; thus, it is impera- tive to monitor monthly counts during the first three months, then once every three months. Some patients continue to maintain satisfactory CD4 cell count (usually >350 cells/mm3) with a low VL (1000–5000 copies/ml) for months and years. The scientific investigation of this issue is continuing (118–122), and involves discussions particularly among the self-help groups and ART providers. However, a recent multicentric trial conducted in the United States demonstrated that this strategy can be associated with an increased risk of HIV disease progression, occurrence of non-AIDS re- 21 PATIENT EVALUATION AND ANTIRETROVIRAL TREATMENT FOR ADULTS AND ADOLESCENTS lated complications (kidney, liver and cardiovascular disease) and death (123), which motivated the interruption of the specific arm study using the structured treatment interruption strategy. Because of these results and the lack of definitive evidence of the benefits of structured treatment interrup- tions strategies in other studies, WHO does not recommend this approach outside clinical trials. . Clinical monitoring of patients with HIV Once a person has been diagnosed with HIV infection, a continuum of care and monitoring should be ensured. .1. Monitoring of laboratory indicators before ART • CD4 cell count ° Repeat every six months, unless there are unexpected results (rapid fall of CD4 cells count or diagnosis of opportunistic infection). ° If starting ART is under discussion (CD4 count is 350 cells/mm3 or less), repeat CD4 count every three months. Statistically, every patient has a median average loss of 50 CD4 cells/ mm3 per year, but they can also drop very quickly, especially with concomitant infection. • Viral load ° Although viral load testing is expensive, the costs of unmonitored ART are much higher (useless drugs, hospital admission in case of failure), as well as bringing a much higher risk for further transmission of HIV due to higher infectivity from an elevated viral load. ° If possible, viral load should be monitored in the same interval as CD4 cell count. The result gives a hint about the intensity of viral replication; low viral load (1000–5000 copies/ml) indicates slow progression, high viral load (>100 000 copies/ml) indicates a high risk for rapid progression. • The general laboratory testing panel (see Table 3 above) should be repeated every six months if there are no changes with regard to initiation of ART or other circumstances (comorbidities, pregnancy, etc.). .2. Monitoring of laboratory indicators in ART patients Successful ART is first reflected by the decrease of viral load; immunological response is a result of viral load, and thus occurs later. ART monitoring is best done with viral load and CD4 count both. • Viral load ° VL should be measured after 4–8 weeks for assessment of whether the regimen is success-ful. Viral load usually falls below the assay’s limits of detection within 16–24 weeks. ° Subsequent monitoring of viral load should be done in intervals of three to four months. ° Once viral load is below the testing threshold which is <50 copies/ml (or 60 or 70 copies/ml, depending on the available test), it should remain there. • CD4 cell count should be repeated every six months, except in case of clinical failure. • The general laboratory testing panel (see Table 3 above) should be repeated every six months if there are no changes in ART or other circumstances. • Depending on specific ARVs used, the frequency for laboratory testing might differ. See Table 10. 22 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Table 10. Frequency of laboratory testing, generally and with specific ARV use Baseline Week 2 Week 4 Week 8 Week 16 Week 24 Week 36 Week 48 Viral load X X X X X CD4 count X X X (X) X Complete blood count X X X X (ZDV) X (X) X Liver Function Test (LFT) X X (NVP) X X (NVP, ZDV, PIs) X (NVP, PIs) X (X) X Cholesterol triglycerides X (PIs) X (PIs) X (PIs) Renal function test X X (TDF) X (TDF, IDV) X (X) X X: laboratory tests to be performed irrespective of the ARVs being administered; X (ARV): laboratory tests to be performed if an ARV in parentheses is being administered; (X): optional test. .3. Immune reconstitution inflammatory syndrome IRIS happens after initiating ART, more often with CD4 counts <100 cells/mm3. If a dormant op- portunistic infection is not diagnosed because of missing clinical symptoms, there may be an in- flammatory reaction after initiating ART, due to an improved and activated immune system, leading to diagnosis of the OI (124, 125). This may occur in up to a third of persons with TB who initi- ate ART (85) (for further information on IRIS in TB/HIV coinfected patients, refer to Protocol 4, Management of tuberculosis and HIV coinfection). The OI often presents differently than usual, for example, in abscesses with Mycobacterium avium-intracellulare (MAI) or curious chest X-rays with PCP. The incidence of IRIS is probably about 10%. MAI and CMV are the most common OIs, but worsening of a treated PCP may also occur (126). In principle, ART should be continued along with treatment of the OI. Low-dose prednisone or prednisolone (20–60 mg/day) may help. ART should be discontinued if irregularly taken due to side-effects of OI treatment or if there is pain with oesophagitis (CMV, herpes, candidiasis). .4. Monitoring adherence Every patient’s adherence to ART should be measured and recorded during routine clinical visits. While there are tools for monitoring adherence (see Annex 5), the preferred method is a standard- ized questionnaire for 14 days or one month. Viral load rebound should always prompt physicians to discuss adherence behavior with their pa- tients. The use of open questions that acknowledge customary low adherence is more likely to elicit full responses. Optimizing adherence in the first four to six months of treatment is crucial to ensuring long-term immunovirological success (127). Several interventions are possible, but priority should be given to interventions aimed at improving adherence in the early months of ART (127–131). Staff should provide individualized support to adherence, based on the needs of each patient at any time during treatment. At every patient visit, health care providers have to ensure that every patient: • has emotional and practical living support • fits the drug regimen into a daily routine • understands that non-adherence leads to resistance • recognizes that all doses must be taken • feels comfortable taking drugs in front of others • keeps clinical appointments 23 PATIENT EVALUATION AND ANTIRETROVIRAL TREATMENT FOR ADULTS AND ADOLESCENTS • understands ARV interactions and side-effects • knows alarm signals and when to see a doctor about them (132, 133). Once a patient is already on ART, additional issues may arise which also need to be addressed in a timely fashion: • treating depression to enhance adherence and improve long-term outcomes (134); and • management of drug interactions and dosages. .. Management of ARV toxicity and side-effects Side-effects are common with ARVs, especially PIs. See Table 11. • LPV/r and NFV can cause severe diarrhoea. • LPV/r is associated with hyperlipidaemia (especially high triglycerides). • Problems with lipid metabolism can occur with nearly all PIs. • Long-term studies of side-effects and increased risk for cardiovascular complications are needed. Toxicity might be a reason for substitution of prescribed ARV to another ARV drug within the same regimen. Switching to another treatment regimen due to toxicity is not recommended. Table 11. Documented toxicity of ARVs and suggestions for management ARV Toxicity Management Hepatic necrosis (life-threatening) NVP • Fever, rash (50%), nausea, vomiting, eosinophilia, elevation of ALT/AST • Usually in first 6–18 weeks, rare after 48 weeks • 1–2% of all NVP treated individuals, higher if CD4 count >250 in females and >400 in males • Monitor LFT at weeks 2, 4, 8 and 16, and then every three months. • Treatment is symptomatic. • Hepatic necrosis is life threatening; in severe clinical situations, stop drugs at once.

Anaemia ZDV • Anaemia and neutropenia (slight decrease is normal with ZDV) • 1–4%, dose dependent • Monitor blood count after 2, 4, 8 and 12 weeks. Macrocytosis with light anaemia (haemoglobin up to 10 g/dl or 100 g/litre) is common. • Treatment is a transfusion of erythro- poetin (very expensive) or changing ZDV to another NRTI (TDF, ABC or d4T). Peripheral neuropathy d-drugs: ddI, d4T • Pain/paraesthesia of extremities • 10–30%, also after years • Monitor peripheral nerves, warn patient. • Treatment is pain management, change of ART.

PLHIV need to take a good deal of different agents due to concomitant diseases or manifestation of HIV and AIDS. Though some drugs are genuinely contraindicated, most drugs that show interactions can still be given in combination; however, the probability of side-effects is then greater, and they should be closely monitored. The effectiveness of contraceptives could also be jeopardized. (See also Protocol 9, Support for sexual and reproductive health of people living with HIV.) Tables 12 and 13 illustrate interactions of drugs with NNRTIs and with PIs. 2 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Table 12.

In Table 12 line 6: EFV strongly increases the levels of midazolam, alprazolam and triazolam while NVP does so less strongly. The significance of this is that there is a definite clinical impor- tance; however, these drugs can still be coadministered. 2. In Table 13 line 4: APV, IDV LPV, NFV, RTV and SQV all increase the levels of carbamazepine, clonazepam, phenytoin and phenobartial while these drugs in turn decrease the levels of the those PIs. The significance of this is that there is definite clinical importance. The combination of any of these should be avoided. Table 13.

Suggested minimum data to be collected at the clinical level The suggested minimum data to be collected are important in the development of key indicators on access to treatment and its success. Such indicators assist managers in decision-making on ways to strengthen and expand these services to all who need them. The following data should be collected at each clinical facility on a regular basis (e.g. monthly, quarterly or semi-annually): • number of HIV patients “seen for care” (seen at least once in the previous 12 months); • number of HIV patients seen for care who are eligible for ART (CD4 <350 cells/mm3); • number of HIV patients seen for care initiating HAART; • number of HIV patients seen for care receiving first-line HAART; • number of HIV patients on HAART changing from first-line HAART to second-line HAART; • number of HIV patients on HAART changing from second-line HAART to salvage HAART; • number of HIV patients interrupting ART treatment, including the reason (e.g. death, toxicity/ side effects, loss to follow-up, ARVs not available, etc.); • number of patients who died while on HAART, including cause of death (e.g. HIV/AIDS related mortality or non-HIV/AIDS related mortality such as accident, overdose or suicide); • number of HIV patients who died within the first 12 months of initiating HAART; and • number of deaths among all HIV patients including cause of death (e.g. HIV/AIDS related mor- tality or non-HIV/AIDS related mortality such as accident, overdose or suicide). 2 PATIENT EVALUATION AND ANTIRETROVIRAL TREATMENT FOR ADULTS AND ADOLESCENTS Annex 1.

Resistance tests Resistance testing needs a minimum of 500–1000 copies/ml; it is not possible with completely suppressed virus. Genotypic resistance testing is based on the analysis of RNA mutations. The amplified genome is se- quenced. Known mutations are encoded for changed susceptibility of the virus. It is an indirect proof of drug resistance. The resistant virus population has to be higher than 20% of the whole population. Virtual phenotypic resistance testing uses computer-based algorithms of genotypic tests connected with large data banks for interpreting results. Phenotypic resistance testing, like microbiological susceptibility testing, examines the ability of viruses to replicate in cell culture in the presence of different agents. It is compared to the same ability of wild-type virus. The 50% inhibitory concentration (IC50) is a marker of drug potency. The results of the test show dif- ferent grades of susceptibility. Which resistance test to use All tests are presently very expensive. Genotypic tests cost €400, phenotypic tests cost €800 (2005). The time between taking the sample and achieving results can be weeks. Basic genotypic testing should show enough evidence for further planning of regimens. First- and second-line regimens do not require the more expensive phenotypic test. When there is a confused ART history, with a lot of already known mutations or an inexplicable treatment failure, a phenotypic test might be justified. For all tests, the individual has to con- tinue taking the failing regimen; otherwise, wild-type virus will overgrow the resistant strains. There are no standardized recommendations for the use of either phenotypic or genotypic resistance testing. 32 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION An ne x 4.

Tools for adherence monitoring Self-reporting is a good adherence marker, but it is not perfect. It seems to overestimate ART adherence more than other methods (142). To be effective, the patient must be willing to disclose problems, particularly face to face. This method may be important in reinforcing the central role of patients in managing their own adherence, as opposed to provider-controlled methods. Provider estimates of adherence have been demonstrated to be poor (143) and are not advisable. Drug-level monitoring is expensive and not yet possible for all ARVs. It is not a method for routine control of adherence, and can only reveal a snapshot of the time the sample is taken (144). In case of low plasma drug levels, adherence has to be discussed. Laboratory markers like mean corpuscular volume of erythrocytes might show adherence to ZDV and to a lesser extent d4T. Medication Event Monitoring System (MEMS) is frequently used in research settings. An electronic de- vice fitted to pill boxes records the removal of the cap. It is associated with predictable virological response to ART (145). It is not possible with blister packs. Pill counts and pharmacy records may be seen as an unwelcome attempt of health care providers to police adherence. They are time-consuming and require patients to bring their medication with them. Pill identification test (PIT) is a novel method that correlates with validated self-reporting measures (146). Patients are invited to distinguish the pills of their regimen from a display of ARVs, including two “twin pills”, which are similar but not identical to their own. The use of surrogate markers is reliable but too late when poor adherence is revealed. Individuals with viro- logical failure on a PI-containing regimen had low PI blood levels, low adherence levels by pill count and an absence of genotypic resistance to PIs, suggesting their treatment failure had been caused by low adherence (147, 148). Providers have to be careful with interpretation of these markers, however, because of other pos- sible reasons for low drug levels (145). 3 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Annex 6.

Glossary Adherence is patient ability to take ARV drugs as prescribed at specific time. High adherence is defined as taking over 95% of doses; low adherence is anything under this level. Backbone is the part of ARV treatment, usually consisting of two NRTIs which are used in combination with an NNRTI or a PI or a PI and fusion inhibitor. “Optimized backbone” means an adjusted combination of probable working NRTIs based on results of resistance testing. Genetic barrier is a description of the number of mutations needed for the virus to be resistant to a drug. Re- sistance with 1 mutation means a low genetic barrier; resistance with 10 mutations means a very high genetic barrier, though this characterization is subject to change. Major mutations are the changes in viral RNA that encode for resistance to particular ART drugs or ART classes. Minor mutations work in combination and can lead to resistance or counteract disadvantages of other major or minor mutations. Nucleoside analogue mutations (NAMs) reveal cross-resistance for most NRTIs. A point mutation is one change in the RNA code resulting in resistance to a drug or class of drugs. For ex- ample, in ART treatment mutation 103 means a resistance to all NNRTIs, resulting from changes in virus at specific point. Resistance is the result of changing amino acids in the RNA strain of the virus. This happens due to the poor replication abilities of HIV. Most changes lead to the death of the virus; other changes are viable, and the resultant virus has the ability to survive the mechanisms of ART. In most cases, resistance leads to poorer viral fitness, meaning a slower HIV replication rate. Though a benefit for the patient at the beginning, it will result in total resistance and high replication rates of the less fit viruses. However, several combinations of resistance patterns can balance this disadvantage, so that some resistance patterns result in a fitter virus in the end. Thymidine analogue mutations (TAMs) are usually a result of ZDV treatment. 40 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Annex 8. Beyond the horizon Research on ART continues. New viral mutations and drug resistance occur regularly – as do new under- standings of the interactions between drugs and the virus. The following are some of the latest ARVs to be approved or to be pending approval, along with new combinations of older drugs. • A once-daily fixed-dose combination of TDF + FTC + EFV has been recently developed and appears to be slightly more effective than the standard ZDV + 3TC + EFV combination (42). • TMC125 (etravirine) is a new NNRTI that has potencies despite existing mutations which encode for NNRTI class resistance (149). • DRV (darunavir) is a new PI with an even higher genetic barrier than LPV/r. Development of resistance is slower than with NFV, APV or LPV/r in vitro. TMC114 is available through an expanded access pro- gramme (EAP) (150). It has been recently approved by the US Federal Drug Administration (FDA). • AG1549 (capravirin) is also a second-generation NNRTI, which is effective despite classical NNRTI mutations. • New coreceptor inhibitors in the fusions molecule are coming. CXCR4- and CCR5-expressing viruses are being fought with drugs that can inhibit one or both of them. New tests for the coreceptor expression of the virus are needed for this treatment. Side-effects are limited for now, though initial experience with this new class has revealed cardiotoxic effects. On August 6, 2007, FDA granted accelerated approval to Selzentry (maraviroc) for combination antiretroviral treatment of adults infected with only CCR5-tropic HIV-1 detectable, who have evidence of viral Replication and have HIV-1 strains resistant to multiple antiretroviral agents. 41 PATIENT EVALUATION AND ANTIRETROVIRAL TREATMENT FOR ADULTS AND ADOLESCENTS References 1.

53 management of opportunistic infections and general symptoms of hiv/aids I. Principles • Management of opportunistic infections (OIs) is an essential component of comprehensive HIV/AIDS treatment and care. • All patients with OIs – irrespective of gender or social class and including injecting drug users (IDUs), sex workers, prisoners, immigrants and other vulnerable populations – should be treated. The decision of whom to treat should be based exclusively on medical considerations. • Treatment for comorbidities should not stop while OI prevention and/or treatment is being pro- vided. 54 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION II. Management of opportunistic infections 1. General information HIV-related infections and illnesses include the following (Table 1). Table 1. hiv-related infections and illnesses Bacterial infections Fungal infections Viral infections Parasitic infections Other illnesses Tuberculosis Bacterial respira- tory infections Bacterial enteric infections Atypical myco- bacteriosis Bartonellosis Candida oesophagitis Cryptococcosis Histoplasmosis Pneumocystis jirovecii pneumonia (PCP) Coccidioidomycosis Herpes simplex virus (HSV) disease Varicella-zoster virus (VZV) disease Cytomegalovirus (CMV) disease Human herpesvirus 8 (HHV8) infection, also known as the Kaposi sar- coma herpes virus (KSHV) Human papillomavirus (HPV) infection Progressive multifocal leu- koencephalopathy Hepatitis B and C (natural course of infection is wors- ened by HIV coinfection) Toxoplasmosis Cryptosporidiosis Microsporidiosis Isosporiasis Leishmaniasis Kaposi sarcoma (KS) Non-Hodgkin lym- phoma (NHL) Cervical cancer Encephalopathy Vacuolar myelopathy The most common OIs in the WHO European Region include: • tuberculosis (TB) • bacterial infections • PCP • herpes infections (including herpes zoster, CMV, HSV 1 and 2 (HSV 1/2) • Candida oesophagitis • Cryptococcus meningitis • toxoplasmosis. Less frequent opportunistic infections and cancers include: • Mycobacterium avium complex (MAC or MAI) disease • KS • NHL • CMV infection (retina, gastrointestinal (GI) tract, encephalitis). The order of infections and cancers in the list may change, due to factors that may or may not be related to the HIV/AIDS epidemic. 2. Initial evaluation Patients with unknown HIV status who present with infections or illnesses that are associated with HIV infection should be offered HIV testing and counselling. The physician should explain to the patient the reasons for offering an HIV test and the importance of knowing the results for correct clinical management. However, patients have the right to refuse testing (opt out). 55 management of opportunistic infections and general symptoms of hiv/aids The initial assessment of HIV status should include: • HIV pretest counselling; • serological testing (typically ELISA and/or rapid tests) for HIV antibodies, followed by a west- ern blot confirmatory test (which indicates HIV infection if the result is positive); and • post-test counselling – whether the result is positive or negative – including information on reducing risky behaviour. If the patient is HIV-positive, an initial clinical evaluation should be made to determine the clinical stage of the infection and identify comorbidities and conditions. (For more information please refer to Protocol 1, Patient evaluation and antiretroviral treatment of adults and adolescents). 3. Counselling patients on OIs and other conditions • Physicians and nurses should counsel all patients and/or families about the chronic nature of HIV infection and the possible appearance of OIs. • Patients should be informed that some OIs can be prevented (see Table 2 below). • They should know that it is essential to diagnose an opportunistic infection early, so that they consult their physician when they suspect any disease progression may be occurring. • They should be counselled on symptoms that might indicate OIs and the need to inform their physician about them: ° dyspnoea: Pneumocystis jirovecii pneumonia (PCP), TB, pneumonia; ° cough: PCP, TB, pneumonia; ° bloody sputum: TB, pneumonia; ° neurological changes: cerebral toxoplamosis, cerebral lymphoma or meningitis/ encephalitis; ° weight loss, fever, night sweats: TB, atypical TB, lymphoma; ° visual impairment: CMV retinitis; ° painful swallowing: candida oesophagitis; or ° diarrhoea: CMV colitis, infection with cryptosporidiae, microsporidiae, salmonellosis, etc. ° visual field loss (reading a newspaper is a good and sensitive test); ° weakness of arms or legs: cerebral toxoplasmosis; ° any change of mental status or behavioural signs that may signal mental health problems (as observed by friends and family members): herpes meningitis, toxoplasmosis, progressive multifocal leukoencephalopathy (PML), etc. ° change in skin conditions or (more often) oral thrush (possible antiretroviral treatment (ART) failure). • Patients should know the importance of monitoring their chronic conditions. ° Patients with chronic hepatitis should have an abdominal ultrasound twice a year because of the risk of hepatocellular carcinoma. ° Patients with a history of tuberculosis should have a chest X-ray once a year. ° Older overweight HIV patients who have hypertension and are on an ART regimen that includes a protease inhibitor (PI) must be checked for cardiovascular disease, diabetes and other conditions. • Patients should be given a checklist that includes a schedule of laboratory and clinical tests to be undertaken on a regular basis. The content of this list may vary due to comorbidities. For further information on counselling issues please refer to Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents. 56 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 4. OI prophylaxis in HIV-infected patients • Certain OIs that may develop in people living with HIV (PLHIV) can be prevented. • Prophylaxis of OIs in PLHIV should be an integral part of OI management. • After initiating ART, it is possible to discontinue primary prophylaxis if the CD4 count has risen over the relevant indication level for 3–6 months (e.g. PCP: >200 cells/mm3, toxoplasmo- sis: >100 cells/mm3, MAI: >50 cells/mm3). See Table 2 below. Discontinuation of secondary prophylaxis should also be possible in the same situation with close monitoring. Always restart prophylaxis when CD4 counts fall below the indication level. Table 2 summarizes the most recent recommendations for prophylaxis strategy. Table 2. oi prophylaxis for hiv-infected patients Pathogen Indication First choice Alternatives Pneumocystis jirovecii CD4 count <200 cells/ mm3 or oropharyngeal candi- diasis TMP-SMZ (cotrimoxa- zole) double-strength tablet POa ODb • TMP-SMZ single-strength tablet PO OD (1) • TMP-SMZ double-strength tablet PO TIWc (Monday, Wednesday and Friday) • Dapsone 50 mg PO BIDd • Dapsone 100 mg PO OD (2) • Pyrimethamine 50 mg + dapsone 50 mg + folinic acid 15 mg OD • Pentamidine inhalation 300 mg every three weeks (3) • Also possible: clindamycin or atova- quone (4, 5) M. tuberculosis Purified protein derivative (PPD) reaction ≥5 mm or recent contact with a case of active TB Isoniazid (INH) 300 mg PO + pyridoxine 50 mg PO OD for 6 months (6) Further research is needed for develop- ing alternative prophylaxis treatment for TB in areas with high prevalence of INH resistance.

Diagnosis and treatment of OIs 5.1. Respiratory infections • Lower respiratory tract infections are the most common recurrent infections in PLHIV. They are usually life-threatening and can be caused by bacteria, viruses (rarely) and fungi (also rarely). 57 management of opportunistic infections and general symptoms of hiv/aids • Patients may present early in the course of HIV infection with bacterial pneumonias, which respond readily to antibiotics (12). • Patients with HIV infection appear to be particularly prone to infections with encapsulated or- ganisms such as Streptococcus pneumoniae and Haemophilus influenzae (13). • Later, and with the onset of immune suppression, patients may develop opportunistic pulmo- nary infections, the most important of which is pulmonary TB. • As cell-mediated immunity deteriorates, patients may develop life-threatening opportunistic infections such as PCP and severe fungal and viral pneumonias. Table 3 summarizes the respira- tory illnesses associated with HIV infection.

Bacterial respiratory infections • Bacterial lower respiratory tract infections are common in the general population, but they are more frequent and more severe in immunosuppressed persons with HIV infection. • S. pneumoniae is the most common lower respiratory tract pathogen. • Patients with bacterial pneumonia present with cough and fever and often have chest pain, dif- ficulty in breathing and tachypnoea. • Chest X-rays may show classic lobar pneumonia, bronchopneumonia or atypical (or absent) infiltrates. 5.1.1.1 Diagnosis The diagnosis of pneumonia is usually made on clinical grounds and by a chest X-ray, which may reveal: • lobar or patchy consolidation • diffuse lung infiltrates or • atypical changes, including cavitary disease. 58 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 5.1.1.2. Treatment • If the patient is not severely ill and no PCP is suspected, treatment may be provided at home according to Tables 4 and 5 below. Table 4. first-line antibiotic treatment of bacterial pneumonia Antibiotic Dose Frequency Route Duration Amoxicillin (Use a penicillin in combination with beta lactamase inhibi- tor if there is a chance of penicillin/ampicillin resistance.) 500–1000 mg TIDa PO 7 days or longer until resolved or: Erythromycin 500 mg QIDb PO 7 days or: Clarithromycin 500 mg BID PO 7 days or: Azithromycin 500 mg OD PO 3–4 days or: Quinolone with pneumococcal activitiy (e.g. moxifloxacin) 400 mg OD PO 7 days or: Doxyciclin 100 mg BID PO 7 days a TID: three times daily. b QID: four times daily. • If patients do not respond to first line treatment over a period of 72 hours (no fever, C-reactive protein (CRP) elevation resolved, leukocyte count is not reliable), the patient should be referred to the hospital and second line treatment prescribed as indicated below. Patients may also re- quire oxygen (in this case PCP should be suspected). • Severely ill patients should be referred for hospital admission immediately. Table 5. second-line treatment of bacterial pneumonia Antibiotic Dose Frequency Route Duration Ceftriaxone + erithromycin 2 g 500 mg OD QID IV* 7 days or: Ampicillin + sulbactam + erythromycin 1500 mg 500 mg TID QID IV 7 days or: Quinolone with pneumococcal activitiy (e.g. moxifloxacin) 400 mg OD IV/PO 7 days or: Chloramphenicol (if other drugs are not available) 12.5 mg (base) per kg of body weight QID IV 7 days *Intravenously. • If patients do not respond to this treatment, consider PCP or TB as a possible diagnosis. The diagnostic gold standard is lavage by bronchoscopy to define the pathogen before starting anti- biotics (14). Also helpful are blood cultures, which have a higher rate of pneumococcal identi- fication and may be done up to five times. 59 management of opportunistic infections and general symptoms of hiv/aids 5.1.2. Atypical mycobacteriosis Mycobacterium avium complex (MAC or MAI) disease is less common than some other OIs. It presents with: • fever • weight loss • night sweats • diarrhoea • wasting. MAC organisms may be found in the blood and excreta of infected persons. A definite infection can be shown with acid-fast bacilli (AFB) in sterile fluids or specimens (blood, cerebrospinal fluid, bone marrow and liver). 5.1.2.1. Diagnosis • Blood cultures on special media are the cornerstone of MAC diagnosis. • In most symptomatic patients, the intensity of mycobacteraemia is such that most or all blood cultures are positive. • Because the liver and bone marrow are often involved in disseminated MAC infection, the bac- teria may be visible in acid-fast-stained biopsy samples from these sites. • Presumptive diagnosis by examination of a biopsied liver specimen saves time. 5.1.2.2. Treatment Table 6. atypical mycobacteriosis treatment Antibiotic Dose Frequency Route Duration First-line treatment (15, 16) Clarithromycin + ethambutol + rifabutin 500 mg–1000 mg BID PO 6 months; decide on clinical grounds 15 mg/kg OD PO 6 months; decide on clinical grounds 300–450 mg OD PO 6 months; decide on clinical grounds Other drugs active against MACa Azithromycin 500–1200 mg OD PO 6 months Ciprofloxacin 500 mg BID PO 6 months Amikacin 15 mg/kg/day or 7.5 mg/kg/day OD BID IV IV No longer than 4 weeks a Rifampicin is not effective against MAC. • Once MAC treatment has been started, and there is indication that the condition is improving and the drugs are well tolerated, ART should be initiated. • Standard procedure is to start on ART 4–6 weeks after MAC treatment has begun. After six months with an improved immune response (CD4 count >100 cells/mm3), reduce MAC treat- ment or stop it and use a secondary prophylaxis. • Stopping the secondary prophylaxis is possible when the immune system is stable and respon- sive for more than 3–6 months. • MAC treatment or secondary prophylaxis should be administered for six months to ensure a successful treatment and avoid relapse. • It is important to begin with treatment for MAC to avoid confusion about whether any side- effects come from MAC drugs or ART. 60 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION • There is the possibility of immune reconstitution inflammatory syndrome (IRIS) after starting ART (see Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents, sections Clinical failure and Immune reconstitution inflammatory syndrome). 5.1.3. Pneumocystis pneumonia • PCP is a common HIV-associated OI, caused by the fungus Pneumocystis jirovecii (formerly known as Pneumocystis carinii). • Patients usually present with cough, shortness of breath and fever. • Occasionally patients with PCP have no chest signs. • Patients with PCP often have features of respiratory failure such as shortness of breath and cya- nosis. • Symptoms may be very severe; an attack of PCP may lead to death if not treated early and ef- fectively. 5.1.3.1. Diagnosis • Diagnosis is often made on clinical grounds when a febrile PLHIV presents with respiratory distress, with or without cyanosis. • The patient may have a non-productive cough, but the main feature of the condition is shortness of breath, with minimal or absent chest signs on physical examination. • Chest X-rays: ° There is not always a ground-glass opacification in the lower zones of both lung fields. ° There may be evidence of patchy infiltrates in both lung fields that mimics bacterial pneu- monia or TB. ° A considerable proportion of patients with confirmed PCP show no changes at all on the X- ray. • Bronchial lavage is the gold standard of diagnosis (14). Diagnosis is confirmed upon finding cysts of Pneumocystis in forced sputum or in bronchial lavage aspirate. • If diagnosis cannot be established due to the lack of a bronchoscope, deteriorating pulmonary function tests or blood gas analysis can be used as indicators. • Treatment should be started immediately upon diagnosis. 5.1.3.2. Treatment Patients should be admitted to hospital for management. Supportive therapy including oxygen may be necessary. Details of treatment are given in Tables 7 and 8 below. Table 7. pcp first-line treatment Antimicrobial agent Dose Frequency Route Duration TMP-SMZ 240/1200 mg <60 kg 320/1600 mg ≥60 kg QID PO/IV 21 days 61 management of opportunistic infections and general symptoms of hiv/aids Table 8. pcp second-line treatment Antimicrobial agent Dose Frequency Route Duration Clindamycin + primaquine 600 mg 15 mg QID BID PO/IV PO 21 days (17) or: Pentamidine (in combination with a broad-spectrum antibiotic to prevent bacterial superinfection, e.g. ampicillin + sulbactam for 10 days) 4 mg/kg IV daily. Dose reduction to 2 mg/kg after 5 days of treatment (18) OD IV 21 days • Severely ill patients will require prednisolone, 80–250 mg PO/IV daily for 1–2 weeks (reduces interstitial oedema). • Combination treatment should also be considered in severe cases, for example, TMP-SMZ and pentamidine. This treatment has incurred a high risk of toxicity according to case reports only. A severe case of PCP requires artificial ventilation or an oxygen saturation (SO2) <92%. Side-effects should be monitored, especially the kidneys (both), pancreas (with pentamidine) and bone marrow (with TMP-SMZ). Lab analysis should be required twice weekly. After successfully treating an acute episode of PCP: • it is necessary to continue secondary prophylaxis with TMP-SMZ 160/800 mg PO OD on a long-term basis; • prophylaxis may be discontinued when the patient’s CD4 count remains stable at >200/mm3 for at least three months. 5.1.4. Other causes of pneumonia in immunosuppressed people • Other causes of pneumonia include fungal and viral infections. They are difficult to diagnose without sophisticated laboratory facilities and are difficult to treat. • Viral pneumonia may be caused by herpes simplex virus, varicella-zoster virus or cytomegalo- virus. • In addition to PCP, other fungal causes of pneumonia include Histoplasma capsulatum, Crypto- coccus neoformans and Aspergillus. 5.1.4.1. Diagnosis • When pneumonia fails to respond to standard treatment, TB or pneumonia caused by viruses, fungi or protozoa should be suspected. • Making a specific diagnosis of fungal or other infections requires sophisticated laboratory tests: ° pp65 early CMV antigen from peripheral blood or bronchial lavage; ° polymerase chain reaction (PCR) for viruses of the herpes family (CMV, HSV 1/2, VZV, Epstein-Barr virus (EBV), human herpes virus 8 and 6 (HHV8, HHV6)) ° special cultures for slow-growing pathogens, such as nocardia. • Close collaboration between physician and microbiologist is needed. 5.1.4.2. Treatment Treatment will depend on the cause, for example foscarnet for CMV infection or long-term antibiot- ics (eight weeks) for nocardia. 62 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 5.2. Gastrointestinal infections (GIIs) • GIIs in PLHIV may be the result of any of the following infections: ° HIV (direct infection of the GI tract) ° bacterial ° fungal ° viral ° protozoal ° parasitic. • Some of the problems may arise from atrophy of the intestinal villi, which commonly leads to malabsorption. • The most common GI problem encountered is diarrhoea, which can be acute, acute-on-chronic or chronic. • Diarrhoea is persistent or chronic in people with AIDS, and an important cause of death among them. • Acute diarrhoea leads to dehydration unless properly treated. • The passing of bloody or blood-stained stools occurs in persons with shigellosis or amoebic dysentery. • Other common GI problems in PLHIV include: ° poor appetite ° nausea ° vomiting ° progressive weight loss. Table 9 summarizes the clinical features, diagnosis and treatment of some of the more common gastrointestinal infections seen in immunosuppressed PLHIV. Table 9. gastrointestinal infections commonly encountered in plhiv Infection Clinical features and diagnosis Treatment Non-typhoid salmo- nelloses Fever, abdominal pain, diarrhoea with or without blood, weight loss, anorexia, hepatosplenomegaly Diagnosis upon blood or stool culture Ciprofloxacin 500 mg PO BID for >2 weeks (19) Shigelloses Fever, abdominal pain, bloody diarrhoea Diagnosis upon blood or stool culture Ciprofloxacin 500 mg PO BID for 7–10 days or: Nalidixic acid 500 mg PO QID for 7–10 days or: TMP-SMZ 160/800 mg PO BID for 7–10 days Cryptosporidiosis Watery diarrhoea, loss of appetite; afebrile Diagnosis upon stool microscopy Paromomycin 1 g PO BID + azithromycin 600 mg PO OD for 4 weeks then: Paromomycin alone for 8 weeks (20, 21). Treatment often fails (22). Microsporidiosis Watery diarrhoea, loss of appetite; afebrile Diagnosis upon stool microscopy Albendazole 400 mg PO BID for 4 weeks. If this does not work try: Mebendazole 200 mg PO TID (albendazole tends to be more successful) (23). 5.3. Candidiasis • Candida albicans colonizes primarily the GI tracts of both men and women. Up to one third of all normal women also carry C. albicans in the vagina. • Women with vaginal candidiasis may develop a vaginal discharge and vulvovaginal pruritus. 63 management of opportunistic infections and general symptoms of hiv/aids • Men with genital candidiasis will develop balanitis or balanoposthitis and will complain of a subpreputial discharge and itchiness of the penis and foreskin. • Oral candidiasis (thrush) leads to inflammation of the mucosal surface together with the appear- ance of adherent white plaques. • C. albicans can infect the skin and cause pruritic dermatitis. • Depending on the level of immune suppression, oral infection may extend to involve the oe- sophagus. • Bronchial and disseminated infections are rare. 5.3.1. Symptoms • Oral thrush can include infection of the: ° buccal mucosa ° tongue ° oropharynx ° gums ° hard and soft palates. • Patients may have no symptoms at all or may complain of a burning sensation in the mouth when eating. • Some patients may complain of white patches in the mouth. • If the thrush has extended into the oesophagus, patients may complain of: ° pain on swallowing food ° retrosternal pain ° excessive salivation. Patients in whom candidiasis occurs most frequently are: • healthy pregnant women and healthy women on oral contraceptives • healthy neonates, especially pre-term infants • those on prolonged courses of broad-spectrum antibiotics • those receiving steroids systemically • those with diabetes mellitus • those with congenital or acquired immunodeficiencies • those suffering from chronic debilitating conditions • the severely malnourished • those with cancer and those receiving chemotherapy or radiotherapy. 5.3.2. Diagnosis • The diagnosis of oropharyngeal candidiasis is made on clinical grounds, based on direct obser- vation and microscopic examination of material obtained from lesions. • Examination of the oral cavity may reveal redness and inflammation of the mucosa, with or without patches of white plaques. • Inflammation may be seen on the palate, throat, gums, tongue and/or the inside of the cheeks. When the tongue is affected, it may be smooth and red, and the papillae normally found on the tongue may be absent. • Diagnosis has to be confirmed by histological examination of tissue biopsies only in cases of suspected Candida oesophagitis or aspergillosis of the lungs. • The symptoms of Candida oesophagitis are: ° difficulty in swallowing ° pain in the chest that increases with swallowing. • Disseminated candidiasis causes fever and symptoms in the affected organs (for example, blind- ness when it affects the eyes). 64 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 5.3.3. Treatment • Localized candidiasis is treated first with relatively inexpensive topical drugs such as nystatin, miconazole or clotrimazole. • In patients with disseminated candidiasis and in those in whom topical treatment has failed, systemic antifungal agents such as ketoconazole, fluconazole, itraconazole or amphotericin B may be given. • For treatment of drug-dependent patients receiving methadone as opioid substitution therapy, see Table 4 of Protocol 5, HIV/AIDS treatment and care for injecting drug users, for the interac- tions of fluconazole, itraconazole and ketoconazole with methadone.

A specimen is needed for culture; susceptibility testing is possible and prescribing of amphotericin B makes more sense. Voriconazole, posaconazole and caspofungin are new drugs encountering rare resistance in any fungi, including Aspergillus; all are very expensive. Voriconazole can interact with ARV drugs, and it should not be prescribed to patients taking efavirenz (EFV) or ritonavir (RTV). Patients receiving both PIs and voriconazole should be closely monitored for possible side-effects (26). 5.4. Cryptococcal meningitis • Cryptococcosis most often appears as meningitis, and occasionally as pulmonary or dissemi- nated disease. • Cryptococcal meningitis is a common systemic fungal infection in PLHIV. • Without treatment, the life expectancy of patients with cryptococcal meningitis is prob- ably less than a month. 5.4.1. Diagnosis Cryptococcosis is relatively easy to diagnose. Patients usually present with headache, fever, neck stiffness and/or cranial nerve palsies, or they may be comatose. However, signs of meningeal in- flammation such as fever and neck stiffness often do not occur. A centrifuged deposit of the cerebro- spinal fluid (CSF) should be examined microscopically after adding a drop of India ink. • The yeasts are visible as organisms surrounded by thick capsules. • The CSF may be cultured for cryptococci. • The cryptococcal antigen test is useful in assessing patients for cryptococcosis and can be per- formed on serum or cerebrospinal fluid. 66 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 5.4.2. Treatment Table 13. cryptococcal meningitis treatment Antifungal agent Dose Frequency Route Duration First-line treatment (27) Amphotericin B + 5-flucytosine 0.7–1.0 mg/kg 25 mg/kg OD QID IV IV 14 days then: fluconazole 400 mg OD PO At least 10 weeks then: fluconazole 200 mg OD PO Lifelong Second-line treatment Amphotericin B + 5-flucytosine 0.7–1.0 mg/kg 25 mg/kg OD QID IV IV 6–10 weeks or: Amphotericin B 0.7–1.0 mg/kg OD IV 6–10 weeks or (in mild cases): Fluconazole 400–800 mg OD PO 10–12 weeks then: fluconazole 200 mg OD PO Lifelong 5.4.3. Secondary chemoprophylaxis or maintenance therapy • Lifelong secondary chemoprophylaxis is necessary; it may be achieved with fluconazole 200 mg orally once daily for life. • Alternate long-term secondary prophylaxis may be achieved with itraconazole 200 mg orally once daily for life. • The need for maintenance therapy with patients who have an improved immune system (CD4 count >200) is presently neither supported nor refuted by concrete evidence. • For treatment of drug-dependent patients receiving methadone as opioid substitution therapy, see Table 4 of Protocol 5, HIV/AIDS treatment and care for injecting drug users, for the interac- tion of fluconazole with methadone. 5.5. Histoplasmosis This uncommon acute or chronic infection is caused by inhaling spores from the fungus Histo- plasma capsulatum. • The outcome of exposure depends on the immune status of the host as well as the size of the inoculum. • Intact cell-mediated immunity is essential for preventing its dissemination. The acute illness is influenza-like, with: ° fever ° anorexia ° arthralgia ° myalgia ° dry cough ° chest pain. • Dissemination occurs soon after initial infection in immunosuppressed patients, who develop: ° weight loss ° oral and skin lesions ° chest symptoms ° liver, spleen and lymph node enlargement. 67 management of opportunistic infections and general symptoms of hiv/aids • Oral lesions may appear as protruding, necrotic ulcers. There may also be perforation of the pal- ate and extensive soft tissue destruction. 5.5.1. Diagnosis Diagnosis is made on clinical grounds and is confirmed by fungal cultures or histological examina- tion of biopsied tissues. • A chest X-ray in acute illness may show: ° hilar lymphadenopathy ° scattered infiltrates ° lower lobe nodules. • Blood and skin tests have been developed for the diagnosis of histoplasmosis, but they are not widely available. 5.5.2. Treatment In normal immune systems, acute histoplasmosis is self-limiting and does not require treatment. In immunosuppressed patients it may be treated as shown in Table 14. Table 14. treatment of histoplasmosis Antifungal agent Dose Frequency Route Duration Amphotericin B 0.7–1 mg/kg OD IV 10 days Source: Johnson et al. (28). This initial treatment is followed, three months after immunoreconstitution with >100 CD4 cells, with one of the following long-term treatments: • itraconazole 200 mg BID PO • fluconazole 200 mg BID PO • amphotericin B 1 mg/kg IV weekly. An alternative is itraconazole 200 mg TID PO x 3 days, then 200 mg PO BID x 12 weeks (taken with a meal and an acidic drink). 5.6. Kaposi sarcoma (KS) • KS is caused by the human herpes virus type 8 (HHV8), also known as the Kaposi sarcoma herpes virus (KSHV). • Any patient suspected of KS should be examined by an oncologist and referred to an oncology clinic as needed. • In HIV-associated immunosuppression, KS is more aggressive, disseminated and rapidly pro- gressive than the endemic disease found in people without HIV infection. 5.6.1. Diagnosis The diagnosis of KS is made on clinical suspicion and confirmed by histological examination of biopsied tissue. Clinical signs include the following. • Lesions may be found anywhere on skin and on any mucosal surface. Skin lesions are hyperpig- mented, blue or purplish papules or nodules and can be associated with lymphoedema. Systemic lesions are commonly found on the palate, gastrointestinal tract, lungs or lymph nodes. • Oral lesions of KS may be found on the hard palate and occasionally on the tongue, throat, tonsils or gums. The lesions are purple papules, usually painless and sometimes large and pe- dunculated. 68 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION • Pulmonary lesions are infiltrative with pleural effusion and often lead to respiratory failure. The condition may be confused with bacillary angiomatosis (bartonellosis), an infective condition seen in PLHIV. 5.6.2. Treatment • KS is a cancer and should accordingly be treated by an oncologist. • It is treatable with radiotherapy if lesions are localized and with cytotoxic chemotherapy if it is generalized. • Cytotoxic drug combinations that have been used with varying degrees of success include: ° liposomal doxorubicin monotherapy (best results) (29–31) ° bleomycin ° vincristine ° daunorubicin ° vinblastine ° etoposide. • Remission is difficult to achieve, and relapses are common. • Localized lesions may be surgically excised or treated with liquid nitrogen (high relapse rate), laser therapy or radiation. Intralesional injection with bleomycin has also been shown to be effective. • KS is usually treatable with ART alone; after successful initiation of ART, KS becomes inactive and slowly disappears. 5.7. Cervical cancer • Cervical cancer is one of the most common types of cancer, causing deaths among women worldwide. The estimated number of new cases per year is 500 000 (32). • Human papillomavirus (HPV) infection is the leading etiologic agent in the development of premalignant and malignant lower genital tract disease, including cervical cancer. • The relative risk of cervical intraepithelial neoplasia (CIN) is 5–10 times higher for women with HIV/AIDS, and abnormal pathology is observed in 20–40% of their Pap smears (33, 34). 5.7.1. Diagnosis When a woman is diagnosed with HIV, a gynaecologic evaluation with pelvic examination and Pap smear should be performed. The examination and Pap smear should be repeated at six months and then annually. For further information, please refer to Protocol 9, Support for sexual and reproductive health of people living with HIV. 5.8. Other cancers Lymphomas – including non-Hodgkin, intracranial and Burkitt types – and squamous cell carcino- ma are more commonly found in immunosuppressed PLHIV than in people who do not have HIV. Any patient suspected of cancer should be examined by an oncologist and referred to the oncology clinic as needed. 5.8.1. Non-Hodgkin lymphoma (NHL) NHL – usually B-cell, very rarely T-cell – occurs commonly in immunosuppressed PLHIV, but its appearance is independent of CD4 cell count. It is thought that EBV or some other virus plays a role in the pathogenesis of this disease. • Malignant NHL cells may be detected in all locations, most often in the lymph nodes, as well as the muscles; organs such as the liver, spleen, lung, heart, brain and GI tract; and (more rarely) the bones. • Symptoms may vary. • Swollen lymph nodes may be palpable in different locations. 69 management of opportunistic infections and general symptoms of hiv/aids • Fever, weight loss and fatigue are common, but not inevitable. • Determining the stage of the disease (I–IV) requires thorough examination – cerebral, cervical, thoracic and abdominal computerized axial tomography (CAT) scans, bone marrow and cere- brospinal fluid biopsies and gastroscopy. • Diagnosis is performed by biopsy of a suspect (enlarged) lymph node, followed by histological examination. 5.8.2. Burkitt-type lymphoma in PLHIV Burkitt-type lymphomas, actually a subgroup of NHLs, are associated with HIV infection and may occur before advanced immunosuppression sets in. This type of tumour is associated with EBV. 5.8.2.1. Diagnosis The diagnosis of Burkitt-type lymphoma is made on careful examination of lymph node and tumour biopsies, confirmed by histological examination. 5.8.2.2. Treatment of non-Hodgkin, Burkitt-type and CNS lymphomas • For NHL, the CHOP regimen is effective and should be administered through six cycles (the number usually needed for complete remission) of the following: ° prednisolone 100 mg/day OD for five days ° vincristine (Oncovin) 1.4 mg/m²/day (maximum 2 mg/day) in one dose on Day 1 of treat- ment ° cyclophosphamide 750 mg/m²/day in one dose on Day 1 ° doxorubicin (hydroxydaunomycin) 50 mg/m²/day in one dose on Day 1. Begin a new cycle every 21 days (Day 22 becomes Day 1, etc.). • The EPOCH regimen, which includes etoposide, prednisolone, vincristine, cyclophosphamide and daunorubicin or doxorubicin, has been shown to be effective in combination with ART. It is based on a regimen of continuous infusion for 96 hours, as follows: ° etoposide 50 mg/m² per day (via central venous line) ° doxorubicin 10 mg/m²/day (via central venous line) ° vincristine 0.4 mg/m²/day (max 2 mg/week) (via central venous line) ° cyclophosphamide 375 mg/m² on Day 5 only, in a bolus (via IV) ° prednisolone 100 mg/day on Days 1–5 OD PO. Repeat the regimen every 21 days until six cycles have been performed. • Burkitt-type lymphoma is managed in the same manner as other lymphomas, and responds to CHOP or EPOCH. Treating this fast-growing lymphoma with more aggressive chemotherapy (such as the B-ALL regimen) is under discussion so there are no specific recommendations at the present time (35, 36). • In Burkitt-type lymphomas, chemotherapy should be followed by radiation of the suspected primary location. • It is possible to treat NHL independently of CD4 cell count, but for prolonged success, ART should be started early. Even during chemotherapy with CD4 count >350, there is a high rate of relapse without ART (37). • For intracranial lymphoma (metastasis), cranial radiation in conjunction with cytotoxic chemo- therapy and steroids is advised (38). • For primary central nervous system (CNS) lymphoma, radiation is the only effective evidence- based therapy. Most patients show CD4 counts <50 with diagnosis. In multivariate analysis, highly active antiretroviral treatment (HAART) is the only additional factor in prolonged re- mission. There are some reports of the effectiveness of HAART alone, so it should be started immediately (39, 40). 70 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 5.9. Neurological infections Invasion of the nervous system by HIV leads to encephalopathy, myelopathy and peripheral neu- ropathy. Numerous neurological syndromes have been ascribed to HIV, including: • cerebral atrophy and degeneration • AIDS dementia complex • cerebellar atrophy • vacuolar myelopathy • facial nerve paralysis • Guillain-Barre syndrome • painful sensory and motor peripheral neuropathy. A number of opportunistic infections, including bacterial, viral and fungal infections, also affect the central nervous system. (For cryptococcal meningitis, please refer to section II.5.4 above.) 5.9.1. Toxoplasmosis Toxoplasmosis is frequently encountered in PLHIV in industrialized countries. It leads to the devel- opment of multiple inflammatory lesions in the brain. In PLHIV, it mainly appears as encephalitis or as disseminated disease. 5.9.1.1. Diagnosis • Toxoplasmosis may be suspected through clinical findings, and patients may present with: ° altered mental status ° fever ° seizures ° headaches ° focal neurological findings, including motor deficits, cranial nerve palsies, movement disor- ders, dysmetria, visual-field loss and aphasia. • Patients who present with evidence of diffuse cortical dysfunction develop evidence of focal neurological disease as the infection progresses. • CAT or MRI brain scans may reveal multiple ring-enhancing lesions. • Serological tests for Toxoplasma antibody (immunoglobulin G, or IgG) may help in establishing the diagnosis in the absence of neuro-imaging techniques. • Most patients with cerebral toxoplasmosis have serological evidence of prior infection with Toxoplasma gondii (IgG-positive). • If toxoplasmosis is suspected, patients should be given a trial of treatment. • Only if they do not respond to this treatment within two weeks should a brain biopsy be consid- ered. • The diagnosis can be confirmed by histological examination of tissue obtained by brain bi- opsy. 71 management of opportunistic infections and general symptoms of hiv/aids 5.9.1.2. Treatment Table 15. treatment of toxoplasmosis Drug Dose Frequency Route Duration Pyrimethamine 200 mg Once (loading dose) PO Single dose Then: pyrimethamine + folinic acid + sulfadiazine 25 mg or 50 mg TID BID PO 6–8 weeks 15 mg OD PO 6–8 weeks 1 g QID PO 6–8 weeks Sources: Katlama et al., Dannemann et al. Chirgwin et al. (41–43). • In the regimen above, sulfadiazine may be replaced by any of the following: ° clindamycin 600 mg QID IV/PO for six weeks ° azithromycin 1200 mg OD PO for six weeks ° clarithromycin 1 g BID PO for six weeks ° atovaquone 750 mg QID PO for six weeks. • Some patients need a very long period of acute treatment. There is no rule for treatment dura- tion. The decision has to be made on clinical grounds and CAT scan if available. • Secondary prophylaxis is given using half the dosage of the acute treatment from the effective regimen, until CD4 count is over 200 cells/mm3 for three months. 5.9.2. Herpes simplex virus (HSV) • HSV infection is commonly encountered in clinical practice. • Following an initial attack, there are frequent recurrences. • In immunosuppressed people the infection may be extensive and persistent and possibly dis- seminated. • Dissemination may lead to infection of the lungs, oesophagus and brain. • HSV may also cause meningoencephalitis and meningitis. 5.9.2.1. Diagnosis • The diagnosis of HSV infection is usually made based on the typical clinical presentation of vesicles and painful superficial sores around the mouth, nose, lips and/or genitals. • It is often difficult to make a diagnosis of disseminated herpes. Special laboratory tests – such as viral culture, radio-immunoblot assay and fluorescent and monoclonal antibody tests – may be necessary. • Typical changes may be seen on CAT scans of the brain, where herpes simplex encephalitis leads to multiple lesions. 72 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 5.9.2.2.

Herpes zoster (48) • Varicella-zoster virus (VZV) often causes disseminated infection after initial exposure. • In children, initial infection results in the development of chicken pox, though most who be- come infected develop no symptoms or signs of infection. • The virus lies dormant in the paraspinal ganglia for years. • With immune suppression, regardless of cause, the virus replicates and produces lesions along the length of a cutaneous nerve in a dermatomal distribution. 73 management of opportunistic infections and general symptoms of hiv/aids • Dissemination can also occur at the same time, with involvement of skin, nervous system, lungs and mucous membranes. • In immunosuppressed patients, zoster is often multidermatomal in distribution, persistent, ex- tensive and associated with severe pain and debility. 5.9.3.1. Diagnosis The diagnosis is usually made on clinical grounds. 5.9.3.2. Treatment Table 20. treatment of dermatomal zoster Antiviral agent Dose Frequency Route Duration First-line treatment Aciclovir 800 mg 5 times a day PO 7–10 days or until lesions crust or: Famciclovir 500 mg TID PO 7–10 days Table 21. treatment of disseminated, visceral or ophthalmic zoster Antiviral agent Dose Frequency Route Duration First-line treatment Aciclovir 10 mg/kg TID IV 7–10 days or: Famciclovir 500 mg TID PO 7–10 days Second-line treatment Foscarnet 60 mg/kg or 40 mg/kg BID TID IV 7–10 days • Post-herpetic neuralgia is a common and seriously debilitating problem. It causes severe pain in dermatomal distribution, usually at the site of the lesions. • Pain control is often necessary and may be achieved with non-steroidal anti-inflammatory drugs (NSAIDs). • If pain control is not achieved, amitryptiline, carbamazepine or phenytoin may be tried. 5.9.4. Cytomegalovirus (CMV) infection CMV may affect multiple systems and organs in immunosuppressed individuals. Symptoms may include: • fever and diarrhoea from CMV colitis • dyspnoea from CMV pneumonitis • blindness caused by CMV retinitis • the appearance of painful ulcers in the mouth, resulting in difficulty eating. 5.9.4.1. Diagnosis • The most frequent localization is the retina and is diagnosed by a specialized ophthalmologist. • Other localizations require sophisticated equipment and costly tests, such as tissue biopsies and deoxyribonucleic acid (DNA) hybridization studies. 74 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 5.9.4.2. Treatment Treatments for CMV GI disease, neurological disease and retinitis are found in Tables 22–24.

(49–53). Secondary prophylaxis can be stopped after six months and immune reconstitution to 100–150 CD4 cells/mm3. 5.9.5. Epstein-Barr-virus-related conditions • Infection with EBV, a herpesvirus, is common in PLHIV and others. • PLHIV have increased amounts of EBV in their oropharyngeal secretions and higher EBV anti- body titres than HIV-negative people. • EBV is thought to cause a number of conditions including: ° oral hairy leukoplakia ° lymphocytic interstitial pneumonitis (LIP) ° non-Hodgkin lymphoma (see section II.5.8.1 above) ° Burkitt-type lymphoma (see section II.5.8.2 above) ° nasopharyngeal carcinoma. 5.9.5.1. Oral hairy leukoplakia • Oral hairy leukoplakia occurs in PLHIV as well as some immunosuppressed transplant recipi- ents. • It is a non-malignant lesion of epithelial cells, presenting as raised, white, corrugated lesions of the oral mucosa, especially on the lateral aspect of the tongue. • It is commonly mistaken for oral candidiasis, as they are frequently found together. • No specific treatment is available for the condition. Patients are generally advised on good oral hygiene. 75 management of opportunistic infections and general symptoms of hiv/aids 5.9.5.2. Lymphocytic interstitial pneumonitis (LIP) • LIP occurs primarily in children, but it also occurs in adult PLHIV. • It is characterized by diffused interstitial pulmonary infiltrates that may be confused with TB or PCP. However, patients with LIP often do not have signs of severe respiratory illness. • No specific treatment is available for LIP. 76 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION III. General symptoms 1. Persistent generalized lymphadenopathy (PGL) in adults • The most common clinical manifestation of HIV infection is symmetric generalized lymph node enlargement. • Enlarged lymph nodes are generally painless, firm, mobile and rubbery and are most easily pal- pated in the neck, submental area, axillae and the groin. • The patient may or may not have other associated symptoms of HIV infection. • PGL is defined as the presence for more than one month of lymph nodes measuring more than 1 cm in diameter in more than one area of the body other than the groin. • PGL is a very common feature of HIV infection. In most cases a lymph node histology only reveals “reactive hyperplasia” or “follicular hyperplasia”. A lymph node biopsy is necessary to establish a cause. 1.1. Diagnosis It is important to palpate lymph nodes specifically in the following areas: • anterior and posterior triangles of the neck • submental area • suboccipital area • anterior and posterior auricular areas • both axillae • epitrochlear areas • both inguinal regions. Patients with PGL caused by HIV infection may have other features of HIV infection, including: • oral thrush • oral hairy leukoplakia • pruritic skin rash • hyperpigmented nails • oral or genital herpes • involuntary weight loss • unexplained fever. PGL may be caused by a number of conditions other than HIV infection, including TB, leukaemia, lymphoma, KS, syphilis, Chlamydia trachomatis (lymphogranuloma venereum), CMV, toxoplas- mosis, EBV, cryptococcosis, histoplasmosis and septic skin conditions, bubonic plague and hepa- titis B. 1.2. Criteria for performing a lymph node biopsy A patient with PGL should be referred for a lymph node biopsy if presenting with any of the fol- lowing: • asymmetrical lymph node enlargement • massive lymph node enlargement (at least one lymph node >3 cm in diameter) • lymph node enlargement over a period of observation • evidence of TB on a chest X-ray • evidence of hilar lymph node enlargement on a chest X-ray • evidence of KS elsewhere • fever, night sweats and weight loss for more than one week. A diagnosis of HIV-related lymphadenopathy does not rule out other serious diseases like lympho- ma in unbiopsied lymph nodes. Therefore, with any change in condition, persistent fever or other suspicious circumstance, a biopsy or lymphadenectomy should be repeated. 77 management of opportunistic infections and general symptoms of hiv/aids 2. Fever • Fever can occur as a result of infection, inflammation or malignancy. Persistent fever in adults is defined as a body temperature of more than 38°C lasting for more than two weeks. • In PLHIV, the only clinical presentation of HIV infection may be fever. Thus, it is important to keep in mind a possible diagnosis of HIV infection when managing a patient who presents with a persistent fever and no obvious cause. • In PLHIV, persistent fever may be accompanied by features of the possible underlying cause, for example pneumonia, TB, gastrointestinal infection or lymphoma. In adults with persistent fever, the following factors may suggest the presence of HIV infection: ° a history of unsafe sexual behaviour ° a partner or child known to be HIV-infected ° other features suggestive of HIV infection, such as: - PGL - oral or genital thrush - oral hairy leukoplakia - pruritic skin rash - oral or genital herpes - involuntary weight loss - darkening of the nails (melanonychia) - hypopigmentation of the lips - thinning and straightening of the hair. 3. Weight loss in adults • HIV infection is a common cause of weight loss. • Severe weight loss is defined as involuntary loss of more than 10% of one’s body weight. • Severe involuntary weight loss in PLHIV is known as HIV-associated wasting syndrome or “slim disease”. • The cause of such wasting is not fully understood. Possible unsubstantiated causes include: ° chronic and recurrent infections ° chronic diarrhoea ° malabsorption ° HIV-induced myopathy ° HIV-induced poor appetite. 3.1. Clinical features • The patient may complain of involuntary weight loss or loss of appetite, with or without fever and diarrhoea. • Patients with HIV-associated wasting disease are ill and emaciated and may be feverish and dehydrated. • Oral candidiasis is commonly found in such patients. • The patient may have other features of AIDS, including features of neurological involvement such as encephalopathy and AIDS dementia complex. 4. Chronic diarrhoea in adults • Adults with chronic diarrhoea complain of frequently passing three or more consecutive loose stools over 28 days. During the course of the illness the patient may also have episodes of acute diarrhoea. • The stool does not usually contain blood, except if there is concomitant dysentery. • The patient usually also has a poor appetite and weight loss. • The patient may also be dehydrated, anaemic and wasted. 78 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION • Adults with chronic diarrhoea often have: ° skin and hair changes typically associated with malnutrition ° hypopigmentation of the lips ° darkly pigmented nails ° oral thrush, hairy leukoplakia or lymph node enlargement. Details on the management of chronic diarrhoea and assessment of dehydration in adults are pro- vided in Protocol 3, Palliative care for people living with HIV. 5. Oral lesions Besides candidiadis (see section II.5.3 above), a large number of other oral lesions may be found in patients with HIV infection. Some of these are described in Table 25. Table 25. description and treatment of oral lesions common in plhiv Condition Description Treatment Gingivitis Swollen and red gums that tend to bleed easily Metronidazole 400 mg PO BID for 7 days or erythromycin 500 mg PO QID for 7 days Pyorrhoea An accumulation of pus in the gingival margin around the teeth Gargling with warm salty water after every meal and brushing the teeth BID Periodontitis A painful condition with rapid loss of the bone and soft tissue supporting the teeth, bleeding of the gums, tooth loss and possible ulceration Local debridement, chlorhexidine mouth washes Amoxycillin 500 mg PO TID or metronidazole 200 mg PO TID for 5 days Aphthous ulcers Painful punched-out ulcers on the mucosal sur- face, usually covered in a purulent exudate and tending to bleed when touched Oral hygiene and treatment with topical steroids Stomatitis Inflammation of the mucosa in the oral cavity, often associated with poor oral hygiene and invasion of anaerobic bacteria Gargling with warm salty water after every meal and brushing the teeth BID Cheilitis Inflammation, redness and eventual pallor of the lips, common in patients with advanced im- munosuppression No specific treatment available; vitamins A, B and C and advice on oral hygiene Secondary syphilis Lesions on the buccal mucosa, including moist papules, “snail track” ulcers and condylomata lata at the angles of the mouth and around the nostrils.

Dermatomycosis • Fungal skin rashes (dermatomycoses) occur commonly in PLHIV and others. • Rashes are usually itchy and dry, with visible scales of dead skin. • The lesions may be found anywhere on the body. 6.1.1. Diagnosis Fungal elements may be found on microscopic examination of skin scrapes. 79 management of opportunistic infections and general symptoms of hiv/aids 6.1.2. Treatment Topical applications of antifungal ointments and creams will usually clear the lesions. The follow- ing may be used for treating dermatomycoses.

Onychomycosis Nails may also become infected with fungi (onychomycosis). The infection can result in discolora- tion, distortion or destruction of the nails. 6.2.1. Diagnosis • Diagnosis is usually made on clinical findings. • Microscopic examination of potassium hydroxide (KOH) preparations of subungual material may reveal fungal elements. 6.2.2. Treatment Table 27. treatment of onychomycosis Antifungal preparation Dose Frequency Route Duration First-line treatment Terbinafine 250 mg OD PO 6 weeks for fingers 12 weeks for toes or: Itraconazole 200 mg BID PO For fingers, 1 week each month for 2 months For toes, 1 week each month for 3–4 months 6.3. Seborrhoeic dermatitis • Seborrhoeic dermatitis is a common presenting feature in PLHIV. It is probably caused by a fungus known as Pityrosporum ovale (also known as Malasezia furfur). • The rash is erythematous and scaly. In persons with HIV infection it may be extensive, persis- tent and recurrent. 6.3.1. Diagnosis • Diagnosis is made on clinical grounds. The rash appears commonly on the: ° face ° area around nostrils ° nasolabial folds ° eyebrows 80 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION ° scalp ° chest ° axillae ° upper trunk ° genital area. Diagnosis can be confirmed by finding fungal elements on microscopic examination of skin scrapes. 6.3.2. Treatment • Frequent skin washing to remove scales is advised. • Shampooing with selenium sulfide shampoo is effective. • Topical applications of 1% hydrocortisone are probably the most effective. Ketoconazole 2% cream has also been shown to be effective. 6.4. Scabies Scabies is caused by the mite Sarcoptes scabei. The female mite burrows into the skin, and the bur- rows appear as raised lines up to several centimetres long. • When a person is infested with scabies mites for the first time, there is usually little evidence of infestation for the first 2–6 weeks. • In subsequent infestations, people usually have become sensitized to the mites, and the symp- toms generally occur within 1–4 days. • The burrowing of the mites under the skin causes a rash, most frequently found on the: ° hands (particularly the web spaces between the fingers) ° folds of the wrist, elbow or knee ° ulnar margins of the forearms ° penis ° breast ° shoulder blades • Burrows and mites may be few in number and difficult to find in some cases. • Severe itching is common, especially at night and frequently over much of the body, including areas where no mites are living. • Norwegian scabies, a more severe form more common among immunocompromised patients, is characterized by vesicles and the formation of thick crusts on the skin, accompanied by abun- dant mites but only slight itching. • Complications due to infestation are usually caused by secondary bacterial infections from scratching. 6.4.1. Diagnosis • The diagnosis is usually made on finding the rash and burrows. • Skin scrapes may reveal mites or mite ova on microscopic examination. 6.4.2. Treatment • The treatment of choice is the topical use of gammabenzene hexachloride 1%, applied to the whole body from the neck down and washed off after 24 hours in adults and 8 hours in children. A single application is sufficient. • Permethrin 1% applications are also useful. Both are applied to affected areas and washed off after 8 hours. • These agents should not be used during pregnancy or lactation or on children until 2 ½ years old. • Ivermectin in a single oral dose of 200 µg/kg is an alternative that is effective for crusted scabies in immunocompromised people. • All members of the household and sexual partners should also be treated. • All clothes, bedding and towels should be washed in hot water, dried and ironed. 81 management of opportunistic infections and general symptoms of hiv/aids 6.5. Staphylococcal folliculitis • Folliculitis is a skin infection that is localized in the hair follicles. • A pustular perifolliculitis occurs commonly in PLHIV. • Usually the condition is caused by Staphylococcus aureus, though other organisms may also be responsible. 6.5.1. Diagnosis • Diagnosis is made on clinical findings. • Lesions are small (less than 5 mm in diameter), and found in multiple erythematous follicles that may have a purulent centre. • Lesions are itchy and often found in clusters. 6.5.2. Treatment Treatment is with antibiotics, such as cephalexin or cloxacillin 500 mg PO QID for 7–21 days. 6.6. Molluscum contagiosum • Molluscum contagiosum is a superficial skin infection caused by the molluscum contagiosum virus. • The infection is spread through close body contact and may occur through sharing clothing, bedding or towels or through sexual transmission. • The incubation period varies from several weeks to several months. • Shaving or scratching may cause the infection to spread. • The infection occurs more commonly in immunosuppressed PLHIV. • In comparison to the lesions found on HIV-negative people, those found on PLHIV are: ° more widespread ° more persistent ° much larger ° more difficult to treat. 6.6.1. Diagnosis • The diagnosis is based on the characteristic appearance of the bumps. • The virus invades the skin, causing the appearance of firm, flesh-coloured papules 2–5 mm in diameter. The lesions contain a white sebaceous material. • The papules can occur anywhere on the body and often remain unchanged for many months, after which they disappear and may or may not reappear. • No diagnostic test for this virus is available. 6.6.2. Treatment The goal of treatment is to remove the soft centre, after which the papule resolves. As such, each lesion needs to be treated individually. Various methods are available for the destruction of the le- sion, including: • curettage • chemical destruction with concentrated phenol • cryotherapy • electrocautery. 82 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION References 1.

89 palliative care for people living with hiv I. Policy, principles and organization of services 1. Policy Palliative care is an approach that improves the quality of life of patients and their families when facing the problems of life-threatening illness. While disease-specific (or “curative”) treatment is directed at reversing the course of an illness, palliative care is primarily focused on the prevention and relief of suffering in progressive, incurable disease. Early identification, sound assessment and effective treatment of pain and other physical, psychosocial and spiritual problems are essential elements in assuring quality palliative care (1–5). Ideally, palliative care and disease-specific treat- ment should be integrated throughout the course of chronic, life-limiting illness, rather than being divided into two completely disconnected treatment approaches. The balance between palliative and curative therapy should depend in a given situation on the etiology of the patient’s symptoms and suffering, the possibility of improving these symptoms through disease-specific and/or pallia- tive interventions, and the availability of resources in the particular country (6). • Palliative care is a core component of comprehensive HIV/AIDS care. • Access to palliative care should not be artificially restricted due to political or social constraints. All patients needing and wanting it should receive it, without exception. • Palliative care should be provided in accordance with the needs of the patient and WHO stan- dards of care. • Treatment for illnesses and conditions should not be withheld at any stage of the disease (for example, tuberculosis (TB) treatment, antiretroviral treatment (ART) or substitution therapy for injecting drug users). • Palliative care should be incorporated as appropriate at every stage of HIV disease, and not only when the patient is dying. 2. Principles The guiding principles of palliative care are to: • provide relief from pain and other distressing symptoms to enhance quality of life; • integrate the psychological and spiritual aspects of patient care; • offer support to help patients live as actively as possible; • offer support to help families cope during illness and bereavement; • draw on experience and communication between the patient and health care provider (nurse, physician, family member, etc) to provide the best combination of interventions and medica- tions; • affirm life and regard dying as a normal process; • strive neither to hasten nor postpone death. 90 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 3. Organization of services • The needs of patients and their families can be addressed by a team approach, including bereavement counselling if indicated. • Palliative care services can be provided as consultative services in hospitals at both inpatient units and outpatient clinics. • Palliative care services can also be provided in the community, in outpatient settings and as home-based care, coordinated with hospital services as needed. • Where available, palliative care specialists should be available to AIDS clinical services. In situations where such access is difficult, AIDS clinics should refer to other institutions where palliative care specialists and services are available. • AIDS care providers should also be familiar with basic principles of palliative care and be able to manage routine problems without needing to refer to palliative care specialists. • Nongovernmental organizations should be involved in delivering palliative care. 91 palliative care for people living with hiv II. General considerations for palliative home care of people living with HIV (PLHIV) Care of patients at home and in the community is an essential component of palliative care. Care- givers’ questions and concerns about safety and infection control can be readily addressed by ref- erences to simple and longstanding practices which decrease risk of contamination with HIV and other bloodborne pathogens. Standard infection control measures to prevent the transmission of HIV have been well established since the 1980s (7, 8). Precautions that should be taken when caring for someone with HIV/AIDS, whether it be in the hospital, clinic or at home, should be the same. These precautions are based on the principles of standard infection control and should be in place and respected at all times. These principles minimize the risk of contamination through infected blood or other body fluids by considering all such fluids as potentially infectious and applying sim- ple and consistent techniques for handling and disposing of them. 1. Precautionary measures at home When palliative care is offered at home, the health care provider (doctor or nurse) should counsel the home care provider (family member, friend or other service provider) on the following points: • Family members and other caregivers can safely care for AIDS patients. There is an extremely low risk of HIV transmission to health care providers and household contacts if the following hygienic practices are respected. ° Wear latex gloves when in contact with blood and bodily fluids. ° Keep wounds covered (on both caregivers and PLHIV); if they become wet with blood or other body fluids, change dressings and dispose of properly. ° Clean up blood, faeces and urine with ordinary household bleach while wearing gloves. ° Keep clothing and sheets that are stained with blood, faeces or other body fluids separate from other household laundry. Use a piece of plastic or gloves to handle soiled items. ° Do not share toothbrushes, razors, needles or other skin-piercing instruments. ° Wash hands with soap and water after changing soiled bedsheets and clothing and after any contact with bodily fluids. • There is no risk from casual household contact (no gloves needed). • Cutlery and other food items, unsoiled clothing and linens, toilets, baths, showers, etc. can be cleaned with ordinary cleaning products. 2. Education on management of symptoms The attending doctor or nurse should provide clear instructions to home caregivers on the manage- ment of symptoms, including: • explanation of symptom management; • education in the most immediately necessary areas, teaching a few skills at a time; • demonstration of skills, such as how to safely give an injection; • verification of skills and knowledge by asking questions and requesting demonstrations; • encouraging the care provider to return if there are any questions or concerns; • ensuring that the caregivers know when and whom to call for help and how to provide back-up, especially in case of side-effects or drug interactions. 92 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 3. Psychosocial issues for affected families When recommending palliative home care for PLHIV, the health care worker needs to consider the family’s emotional state, the home environment and any socioeconomic issues that may affect the patient and family. Significant factors may include: • frustration, sadness, grief; • family members’ fear of becoming infected if they are not already known to be; • anger and blame for the infection that are directed towards the patient; • stigmatization and discrimination of the patient, family members, friends and other caregivers; and • concerns about the economic impact of life-threatening illness on the main family wage- earner(s), and the possibility of orphaning any children. Actions to be taken include: • assessing if the family is physically and emotionally capable of caring for the patient and other home responsibilities (may include age-related concerns); • counselling and educating family caregivers; • providing psychological support, referrals to HIV/AIDS psychologists and/or peer support groups; • assisting in planning for and ensuring care of orphans; • referral to social service agencies for financial, legal and other assistance. 93 palliative care for people living with hiv III. Initial evaluation The initial evaluation of PLHIV in need of palliative care, like the initial clinical evaluation of newly diagnosed PLHIV, should include a complete history, physical examination, general staging of the illness (i.e. WHO Categories I–IV), and assessment of any active problems or other issues requiring intervention or follow-up (see Box 1). (See Protocol 1, Patient evaluation and antiretroviral treat- ment for adults and adolescents.) In addition, the palliative care-focused evaluation should identify any significant physical symptoms; the types and degree of pain; any emotional, psychological or spiritual issues; and any family or social problems. Box 1. initial evaluation of plhiv in need of palliative care History • Present illnesses and treatments administered • Past medical history, including all comorbidities and past HIV-related complications, other major illnesses, hospitalizations, surgeries and date of HIV diagnosis • Medication history • Substance use and dependence history, including treatment (see Protocol 5, HIV/AIDS treat- ment and care for injecting drug users) • Family history • Social history • Social resources • Financial issues • Current symptoms (i.e. pain, weight loss, anorexia, fatigue, fevers, night sweats, insomnia, sadness, anxiety, dyspnoea, cough, nausea/vomiting, diarrhoea) • Chronology of symptoms • Exacerbating and relieving factors • Current medications or other treatment for symptoms • Cause, type and grade of paina • Symptom cause, type and characteristics • Impact: ° of symptoms on functional capabilities ° of symptoms on each other ° of specific therapies on each symptom ° of symptoms on patient’s quality of life • Mental health history and treatment (e.g. depression, anxiety disorder, delirium, psychosis), and any current mental health problems Physical examination • Full clinical examination • Systems review including: ° constitutional (fatigue, anorexia, fevers, weight loss) ° neurological ° mental status ° dermatological Other examinations and tests as required a Grading of pain should be on a 0 to 10 scale, with 0 being no pain and 10 being the worst pain imaginable. 94 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION The initial palliative care assessment should result in a staging of the HIV infection; identification of comorbidities and other relevant medical, mental health, social and environmental conditions; classification and grading of pain and other symptoms; and an initial plan for addressing the mul- tiple needs of the patient and the patient’s family in accordance with the conceptual framework of palliative care outlined in section I above. 95 palliative care for people living with hiv IV. Treatment Since early in the HIV/AIDS epidemic, patients with HIV have been found to have a high prevalence of pain and other symptoms (9–24). The source of pain (and most of the other common symptoms of HIV/AIDS) can be HIV itself, specific opportunistic infections or malignancies, medications used in the treatment of HIV, and/or other coexisting conditions. Accordingly, the most effective approach to symptom management may be treating an underlying condition, controlling HIV infec- tion, changing medications to reduce toxicity and/or treating the symptoms themselves. 1. Pain management Pain is generally categorized as nociceptive or neuropathic. Nociceptive pain results in the stimulation of intact nociceptors (pain receptors), and it is subdivided into: • somatic pain (involving skin, soft tissue, muscle and bone) • visceral pain (involving internal organs and hollow viscera) (25). Nociceptive pain generally responds to non-opioid and opioid analgesics. In PLHIV, neuropathic pain occurs in at least 40% of patients with advanced disease (21). It is mostly due to the syndrome of distal symmetric polyneuropathy (DSP), which is an axonal neuropa- thy apparently caused by HIV infection itself and characterized by numbness, tingling, a “pins and needles” sensation and allodynia, especially involving the distal lower extremities and feet (26–31). Neuropathic pain generally responds to non-opioid or opioid analgesics together with adjuvant medications such as antidepressants or anticonvulsants (1, 2, 24, 29, 31, 32). In addition, certain antiretroviral agents used in ART, e.g. didanosine (ddI) and stavudine (d4T), have been associated with a similar toxic neuropathy with comparable symptoms that also affect the distal lower extremities. In these cases, a change in antiretroviral agent(s) may result in some improvement, though that is not always the case. Pain management should begin with a thorough and systematic assessment of pain, including pos- sible etiologies, and the specific nature of pain. Important characteristics include intensity, type, interference and relief. • Pain intensity. Use of a 10-point numeric scale is standard, with 0 as no pain and 10 the worst possible pain. It is particularly helpful to use the same scale over time in an individual patient, to monitor any changes on a continuing basis (see Fig. 1 below) (33). • Pain type. Nociceptive pain may be described as aching, stabbing, deep, dull, pulsating; neuro- pathic pain may be described as burning, tingling, “pins and needles”, numbness or otherwise abnormal sensations. Such characterizations can help guide analgesic choice, especially for suspected neuropathic pain. • Pain interference. The impact of pain on patients’ functional status, ability to perform usual daily activities and emotional state should also be documented. • Pain relief. Conditions or interventions which increase or decrease pain should be elicited. 96 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Fig. 1. pain intensity Scales Simple Descriptive Pain Intensity Scale No Pain Mild Pain Moderate Pain Severe Pain Very Severe Pain Worst Possible Pain 0–10 Numeric Pain Intensity Scale 0 1 2 3 4 5 6 7 8 9 10 No Pain Moderate Pain Worst Possible Pain Visual Analog Scale (VAS) No Pain Pain as bad as it could possibly be Note: a 10-cm baseline is recommended for any graphic representation of these scales. Source: Acute Pain Management Guidelines Panel (33). Severe chronic pain most often occurs with malignancies, chronic pancreatitis, joint problems and severe neuropathy. A graded approach for using analgesics to treat mild, moderate and severe pain, along with the potential use of adjuvant medications at each stage, can be helpful (see Fig. 2) (1). Table 1 below, expands on this approach indicating starting doses and other recommendations. 97 palliative care for people living with hiv Fig. 2. who analgesic ladder for management of pain in plhiv Pain persisting or increasing Strong opioid +/– non-opioid +/– adjuvant Non-opioid +/– adjuvant Weak opioid +/– non-opioid +/– adjuvant Pain persisting or increasing 1 MILD PAIN 2 MODERATE PAIN 3 SEVERE PAIN PAIN RELIEF +/–: with or without. Mild pain: 1–3 on the 0–10 Numeric Pain Intensity Scale; moderate pain: 4–6; severe pain: 7–10. Non-opioid analgesics: ibuprofen, indomethicin, acetylsalicyclic acid, paracetamol. Adjuvants: amtriptyline, imipramine, gabapentin, carbamazepine, valproic acid. Weak opioids: codeine, hydrocodone. Strong opioids: morphine, oxycodone, methadone, hydromorphone, fentanyl. Notes: Adjuvant medications are particularly helpful for neuropathic pain. Not all analgesics will be available in all settings. Source: adapted from WHO (1). Some specific considerations are worth noting: • If possible, administer analgesics orally or (assuming no history of rectal abscesses, rectal in- fection, etc.) rectally. Intramuscular pain management, though sometimes required for severe pain not responding to oral regimens, can be painful in itself and may pose a risk of infection. If necessary and available, intravenous or subcutaneous infusion of strong analgesics can be used as an alternative route of administration, especially in hospital settings but also in the home if resources permit. • Tailor the analgesic regimen to patterns of sleep, i.e. if possible do not awaken the patient to give pain medication. • Administer analgesia before the effects of the previous dose have worn off. • Start with a low dose and increase gradually until the patient is comfortable. • For breakthrough pain,1 give an extra dose (50–100% of the 4-hourly dose) in addition to the regular schedule. • While aspirin can be effective in controlling mild-to-moderate pain, care should be taken in us- ing it due to the increased bleeding tendencies of PLHIV, especially in patients with clinically significant liver disease. Paracetamol may also be problematic in patients with active liver dis- ease and should be used cautiously, generally not exceeding 2 g/day in such patients. 1 Breakthrough pain is pain that “breaks through” a regular pain medicine schedule. Breakthrough pain comes hard and fast and can last up to an hour. It may be an intensified all-over dull pain, or come as a localized sharp stab or fiery sensation. Breakthrough pain differs from person to person and is often unpredictable. 98 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Table 1. pain management Type of pain or treatment Usual starting dose (adults) Recommendations A. Medical treatmenta Step 1: mild pain Non-opioids Paracetamol 500–1000 mg every 4–6 hours (also available in rectal sup- positories) Do not exceed 4 g/day. Use with careful monitoring in patients with liver disease; toxicity is dose-related. Ibuprofen 400 mg every 6 hours Maximum 2.4 g/day. Contraindicated in pa- tients with gastrointestinal bleeding and/or bleeding disorders. Use with caution in patients with liver disease. Aspirin (acetylsalicylic acid) 325–500 mg every 4 hours, or 1000 mg every 6 hours Do not give to children under 12 years old. Contraindicated in patients with gastroin- testinal bleeding and/or bleeding disorders. Use with caution in patients with liver disease. Step 2: moderate painb Non-opioids Plus Opioidsc Paracetamol 500–1000 mg every 4–6 hours (also available in rectal sup- positories) Do not exceed 4 g/day. Use with careful monitoring in patients with liver disease; toxicity is dose-related. Ibuprofen 400 mg every 6 hours Maximum 2.4 g/day. Contraindicated in pa- tients with gastrointestinal bleeding and/or bleeding disorders. Use with caution in patients with liver disease. Aspirin (acetylsalicylic acid) 325–500 mg every 4 hours, or 1000 mg every 6 hours Do not give to children under 12 years old. Contraindicated in patients with gastroin- testinal bleeding and/or bleeding disorders. Use with caution in patients with liver disease. Codeine 25–50 mg every 4 hours If codeine is not available consider alternating aspirin and paracetamol. Codeine is available in fixed- dose combinations with aspirin or paracetamol, with 325–500 mg paracetamol or aspirin and 25–60 mg codeine. Maximum daily dose for pain 180–240 mg due to constipation, otherwise switch to morphine. Prevent constipation through use of a stool softener and bowel stimulant, use laxatives if needed. For IDUs, use a non-steroidal anti-inflam- matory (ibuprofen) before offering codeine. Be aware of possible abuse of codeine or morphine-related drugs. Refer to Protocol 5, HIV/AIDS treatment and care for inject- ing drug users. Tramadol 50–100 mg every 4–6 hours — 99 palliative care for people living with hiv Type of pain or treatment Usual starting dose (adults) Recommendations Step 3: severe pain Non-opioids Plus Opioidsc Paracetamol 500–1000 mg every 4–6 hours (also available in rectal sup- positories) Do not exceed 4 g/day. Use with careful monitoring in patients with liver disease; toxicity is dose-related Aspirin (acetylsalicylic acid) 325–500 mg every 4 hours, or 1000 mg every 6 hours Do not give to children under 12 years old. Contraindicated in patients with gastroin- testinal bleeding and/or bleeding disorders. Use with caution in patients with liver disease. Oral morphined 10–20 mg every 3–4 hours in tablet or liquid form IV or IM morphine 5–10 mg every 3–4 hours Dose can be increased by 50% after 24 hours if severe pain persists. There is no ceiling dose. Oxycodoned 5–10 mg, every 4 hours Dose can be increased by 50% after 24 hours if severe pain persists. Hydromorphone 2–4 mg every 4 hours Fentanyl transdermal patch 25 mcg, replaced every 72 hours If oral morphine is not available, and injectable morphine is used rectally, use 5 mg/5 ml or 50 mg/5 ml, according to need and rate of respiration (no ceiling; consider withholding if respiration rate is <6/min- ute). Prevent constipation through use of a stool softener and bowel stimulant; use laxatives if needed. Pain management for IDUs is the same as for non-IDUs, only the needed dose of the analgesic is usually higher. In case of opioid substitution therapy (OST), the substitution dose should be maintained and opioid analgesics added. Be aware of possible abuse of codeine and of morphine-related drugs. Refer to Protocol 5, HIV/AIDS treatment and care for injecting drug users. Approximately 4–6 times more potent then morphine. Not for use in opioid-naive patients. B. Treatment for special pain problems Neuropathic pain Burning pains, abnormal sensation pains, shooting pains, “pins and needles” sensation. Common causes include HIV-related peripheral neu- ropathies and herpes zoster. Use opioids with or without non-opioid analgesics, as above, along with one of the following adjuvants Amitriptyline 25 mg at night (because of side- effects, e.g. fatigue) or 12.5 mg twice daily (BID) Wait 2 weeks for response, then increase gradually to 50 mg at night or 25 mg BID. As there is no sudden relief, wait 5 days minimum for a response. Gabapentin Maximum 2.4 g/d if on highly active antiretroviral treatment (HAART) regimen with prote- ase inhibitor (PI) Refer to Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents, section on Drug interactions with ARVs. Carbamazepine 200–400 mg every 6 hours Monitor white blood cell count and drug interactions. Clonazepam 0.5–1.0 mg 2–3 times daily — 100 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Type of pain or treatment Usual starting dose (adults) Recommendations Muscle spasms Diazepam 5–10 mg 2–3 times daily Tetrazepam 50 mg/day, up to 200 mg/day in 2 doses Baclofen Begin with 5 mg three times daily (TID), increase every 3 days up to 25 mg TID. IDUs: before administering consider carefully the possibility of polysubstance misuse. Should only be used in the short term (6–8 weeks maximum). In terminal care, with no referral and: • swelling around tumour; • severe oesophageal candidiasis with ulceration and swallowing problems; • nerve compression; or • persistent severe headache due to increased intracranial pres- sure. Dexamethasone 2–6 mg per day Prednisolone 15–40 mg for 7 days or as pro- vided by trained health worker Helpful in terminal care; improves appetite and makes patient feel comfortable. Reduce dose to lowest possible. Withdraw if no benefit in 3 weeks. Dexamethasone is about seven times stronger than prednisolone. If prednisolone needs to be used, multiply the dexametha- sone dose by seven. Corticosteroids may cause candidiasis. Gastrointestinal pain from colic Butylscopolamine 10-20 mg 2-3 times daily Butylscopolamine has different half-lives: IV is more rapid, while per os (PO) is slower, though dosage remains the same for both. Start with IV, followed by PO; if stable PO, dose with IV for peaks. Codeine 30 mg every 4 hours Codeine can cause constipation and worsening of symptoms in injecting drug users (IDU). Be aware of possible abuse of codeine or morphine-related drugs. Trimebutin 100–200 mg TID before meals — C. Non-medical treatment Psychological, spiritual and/or emotional support and counsel- ling to accompany pain medication Not applicable Pain may be more difficult to bear when accompanied by guilt, fear of dying, loneli- ness, anxiety or depression. Relieve fear and anxiety by explaining events. Relaxation techniques, including physical methods, such as massage and breathing techniques; and cog- nitive methods, such as music Not applicable Contraindicated if the patient is psychotic or severely depressed. a Administer only one drug from the non-opioid and opioid choices at a time; aspirin every 4 hours can be given along with paracetamol every 4 hours by offsetting the schedule so that the patient is being given one of the two every 2 hours. b See equianalgesic dose chart in Annex 1, which can be used to help select or substitute for specific opioid analgesics. c If pain is controlled, reduce morphine rapidly or stop if used for only a short time; reduce gradually if used for more than 2 weeks. d Morphine and oxycodone are frequently available in long-acting (sustained-release) forms; the guidelines above refer to acute pain management, which should be initiated with short-acting preparations and then converted to long-acting formulations if the need for chronic analgesia persists. 101 palliative care for people living with hiv Morphine and other opioids commonly cause side-effects which can generally be prevented or treated easily through dose adjustment or other simple symptom-specific interventions, as out- lined in Table 2. Many of these symptoms may diminish on their own over time. Occasionally, if symptoms are persistent and treatment-limiting with a particular opioid, it may be necessary to change to another opioid medication. For equianalgesic dose equivalents for opioids, please refer to Annex 1. Table 2. Management of side-effects of morphine and other opioids Side-effect Managmenet Constipation Increase consumption of fluids and fibre with fruits and vegetables or bran supplements. Give stool softener (docusate 200–800 mg/d) at time of prescribing plus stimulant (senna 7.5–8.6 mg tablets, 2–4 BID). If no improve- ment, add laxative such as macrogol 13.125 g/dose once or twice a day, or lactulose 10–20 ml TID, and if still no improvement, bisoco- dyl 5–15 mg oral tablets or rectal suppositories as needed. Prevent by using some or all of the above measures for prophylaxis (unless chronic diarrhoea). Nausea and/or vomiting An antiemetic usually resolves the problem in several days; may need round-the-clock dosing. Respiratory depression (rare if oral mor- phine is titrated against pain) Usually no need to intervene if respiratory rate >6–8/min. If severe, consider withholding next opioid dose, then halve the dose. Confusion or drowsiness (due to the opioid) Usually occurs at start of treatment or dose increase. Usually resolves within a few days. Can occur at end of life with renal failure. Halve dose or increase interval between doses. Itching/twitching (myoclonus – if severe or present during waking hours) If on high dose, consider reducing or alternating doses or using two opioids. Re-evaluate pain and treatment; pain may not be morphine respon- sive. Somnolence Extended sleep can be from exhaustion due to pain. If condition persists more than 2 days after starting, reduce dose by half. Note: Reducing morphine when the cause of pain is under control depends on the length of use. If morphine has been used only for a short time, stop or rapidly reduce dosage. If it has been used for >2 weeks, reduce dosage gradually and watch for withdrawal symptoms. 102 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Table 3. oral morphine instructions for family and community care providers Purpose Instructions To teach family and community care pro- viders how to give small amounts of oral morphine with a syringe and how to deal with side-effects. Oral morphine is a strong painkiller that is only available from spe- cially trained health workers. • To administer oral morphine: ° pour a small amount of morphine liquid into a cup; ° draw up the exact dose into a syringe (using the ml marks); and ° drip the liquid from the syringe into the mouth (there should be no needle on the syringe). • Give prescribed dose regularly every 4 hours – do not wait for pain to return. • Give a double dose at bedtime. • If the pain is getting worse or reoccurs before the next dose is due, give an extra dose and inform the health worker – the regular dose may need to be increased. • Nausea usually goes away after a few days of morphine and does not usually come again. • Constipation should be prevented in all patients except those with diarrhoea; give local remedies or a laxative such as senna. If constipation does occur, see Table 2 above and section IV.11 below for management. • Dry mouth: give sips of water. • Drowsiness usually goes away after a few days of morphine. If it persists or gets worse, halve the dose and inform the health worker. • Sweating or muscle spasms: notify health worker. Table 4. pain management instructions for family and community care providers Purpose Instructions To teach family and community care provid- ers how to administer pain medication • Explain frequency and importance of administering pain relief medicine regularly and of not waiting for the pain to return. • Stress that dose should be given before the previous dose wears off. • Write out instructions clearly. To advise family and community care pro- viders on additional methods of pain control. Discuss how to control pain through: • emotional support; • physical methods: touch (stroking, massage, rocking, vibration), ice or heat, deep breathing; • cognitive methods: distraction, music, imagery, etc.; and • spiritual support, including meditation and prayer, while respect- ing the patient’s beliefs. 2. Symptom management Patients with HIV/AIDS may experience a wide range of symptoms, involving virtually every major organ system, as a result of specific opportunistic infections, malignancies, comorbidities, medication toxicity, substance abuse or HIV infection itself. Many studies from different countries have documented a high prevalence of symptoms in patients with AIDS (see Table 5) (34). Table 6 summarizes some of the common symptoms in HIV/AIDS and their possible causes, grouped primarily by organ system, and it also indicates some of the disease-specific and/or palliative care interventions that may be applied in individual cases. Tables 7–26 present symptom-specific pal- liative care interventions in more detail, along with suggestions that may be useful for home care providers. Whenever possible, the particular condition causing the symptom should be treated (e.g. cryptococcal meningitis that is causing headaches), but often it is just as important to treat the symptom itself (for example, loperamide or codeine for chronic diarrhoea that is not due to a specific pathogen). 103 palliative care for people living with hiv Table 5. prevalence of symptoms in patients with aiDS Symptoms Prevalence Fatigue or lack of energy 48–45% Weight loss 37–91% Pain 29–76% Anorexia 26–51% Anxiety 25–40% Insomnia 21–50% Cough 19–60% Nausea or vomiting 17–43% Dyspnoea or other respiratory symptoms 15–48% Depression or sadness 15–40% Diarrhoea 11–32% Constipation 10–29% Source: based on available descriptive studies of patients with AIDS, predominantly with late-stage disease, 1990–2002, in Selwyn & Forstein (34). 104 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Ta bl e 6. co m m o n sy m pt om s in p at ie nt s w it h ai D S an d po ss ib le d is ea se -s pe ci fi c an d sy m pt om -s pe ci fi c in te rv en ti o ns Ty pe Sy mp tom s Po ssi ble ca us es D is ea se -s pe ci fic t re at m en t Sy m pt om -s pe ci fic t re at m en t Co ns tit ut ion al Fa tig ue , w ea kn ess AI DS Op po rtu nis tic in fec tio ns An ae mi a HA AR T T re at s pe ci fi c in fe ct io ns Er yth rop oie tin , tr an sfu sio n Co rti co ste roi ds (p red nis on e, de xa me tha so ne ) Ps yc ho sti mu lan ts (m eth ylp he nid ate , d ex tro am -

Management of weight loss Table 7. Management of weight loss Condition Treatment and dosages (for adults) Suggestions for home care General weight loss Encourage the patient to eat, but do not force as vomiting may result. Offer more frequent smaller meals of the patient’s preferred foods. Consider possible reasons for weight loss (tumours, Candida oesophagitis, TB, atypical mycobacteria, CMV colitis, cryptosporidiosis). Avoid cooking close to the patient. Let the patient choose the foods he/she wants to eat from what is available. Accept that intake will decrease as the patient becomes more ill. Seek help from trained health worker in case of rapid weight loss, consistent refusal to eat or inability to swallow. Anorexia and severe fatigue Prednisolone 5–15 mg daily for up to 6 weeks Try to stimulate appetite. Nausea and vomiting Provide antiemetics (see Table 9). Offer more frequent smaller meals of the patient’s preferred foods; do not force the person to eat. Thrush or mouth ulcer See Table 10. — Diarrhoea See Table 13. — 4. Management of fever Fever may be a side-effect of antiretroviral (ARV) regimens; if suspected, see Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents, Table 11. Table 8. Management of fever Condition Treatment and dosages (for adults) Suggestions for home care General fever Assess and treat cause. Give paracetamol or acetylsalicylic acid every 4 hrs (no more than 8 tablets paracetamol in 24 hours). Make sure the patient remains hydrated. Encourage the patient to drink water, diluted tea or fruit juice frequently. Use physical methods like wet compress- es or ice packs. 109 palliative care for people living with hiv 5. Management of nausea and vomiting Nausea and abdominal discomfort may be side-effects of ARV regimens or due treatment of op- portunistic infections; if suspected, see Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents, Table 11, and Protocol 2, Management of opportunistic infections and general symptoms of HIV/AIDS, section on Gastrointestinal infections. Table 9. Management of nausea and vomiting Condition Treatment and dosages (for adults) Suggestions for home care Nausea and vomiting Metoclopromide 10 mg every 4–8 hours Haloperidol 1–2 mg once daily (OD) or BID Chlorpromazine 25–50 mg every 6–12 hours Cyclizine 50 mg up to four times daily Clemastine 1 mg BID Cetirizine 10 mg OD Hydroxyzine 25–50 mg three or four times daily Ondansetron 8 mg OD or BID Seek foods the patient likes that cause less nausea. Offer smaller meals and have the patient drink frequently and slowly. Seek help from trained health worker for: • vomiting more than once a day • dry tongue • passing little urine • abdominal pain. 6. Management of mouth ulcers or pain on swallowing Be aware that mouth ulcers or painful swallowing may be caused by CMV ulcers of the mouth or oesophagus, herpes infection or candida oesophagitis. Table 10. Management of mouth ulcers or pain on swallowing Condition Treatment and dosages (for adults) Suggestions for home care General — Use soft toothbrush to gently scrub teeth, tongue, palate and gums. Rinse mouth with diluted salt water (a pinch of salt in a glass of water) after eating and at bedtime (usually 3–4 times daily). Topical anaesthetics can provide some relief. Dissolve 2 aspirin in water and rinse the mouth with it up to four times a day. Pain relief may be required (see Table 1). Remove food leftovers with gauze/cloth soaked in salt water. Soft foods may decrease discomfort. Textured foods and fluids may be swal- lowed more easily. Avoid very hot, cold or spicy foods. Candida (oral thrush) Miconazole buccal tablets 1 tablet OD for 7 days If severe and/or no response: Fluconazole initial loading dose: 200 mg (1 day); maintenance: 100 mg daily for 10–14 days or until symptoms resolve Aphthous ulcers Prednisolone applied as crushed grains Dexamethasone solution as mouthwash Kenalog cream applied to sores Herpes simplex Aciclovir 400 mg PO 5 times a day Foul-smelling mouth due to oral cancer or other lesions Metronidazole mouthwash: crush 2 tab- lets in water and rinse mouth. 110 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 7.

Management of diarrhoea Diarrhoea may be a side-effect of ARV regimens (see Protocol 1, Patient evaluation and antiret- roviral treatment for adults and adolescents, Table 11); other causes include CMV colitis, crypt- osporidiosis, microsporidiosis, giardiasis, Kaposi sarcoma, other infective agents, etc. Table 13. Management of diarrhoea Condition Treatment and dosages (for adults) Suggestions for home care General Increase fluid intake, to prevent dehydra- tion. Use oral rehydration solution (ORS) if large volume of diarrhoea. Suggest a supportive diet. Give constipating drugs, unless there is blood in stool or fever, or if patient is younger than 5 or elderly. Loperamide 4 mg to start, then 2 mg af- ter each loose stool (maximum 12 mg/day, though some patients need more) Or (if approved): • codeine 10 mg TID (up to 60 mg every 4 hours); or • oral morphine 2.5–5.0 mg every 4 hours (if severe) Encourage the patient to drink plenty of fluids to replace lost water (given in small amounts, frequently). Increase frequency of small amounts of food intake, such as rice soup, porridge, ORS, bananas, other soups. Be careful with milk and chocolate. Special care for rectal area: • after the person has passed stool, clean with toilet paper or soft tissue paper; • wash the anal area three times a day with soap and water; and • if the patient feels pain when passing a stool, apply petroleum jelly around the anal area. Seek help of a trained health worker for any of the following: • vomiting with fever • blood in stools • diarrhoea for more than 5 days • increasing weakness • broken skin around the rectal area • perianal ulcers. Rectal tenderness Local anaesthetic ointment or petroleum jelly Incontinence Petroleum jelly to protect perianal skin 10. Assessment of dehydration in adults An assessment of the state of hydration is essential in the management of persons with chronic diarrhoea.

Encourage consumption of fruit (includ- ing dried fruit), vegetables, linseed por- ridge, soft foods. Give a tablespoon of vegetable oil before breakfast. Have the patient gently put petroleum jelly or soapy solution into the rectum, or do it yourself if the patient cannot. For this procedure, as for any contact with potentially infective matter, use protective gloves. Other constipation Give stool softener/bulk agents, varying the dose for the individual: • a bulk-enhancing agent the first time, e.g. bran 4 tablets/day or psyllium 2–3 tablespoons in water/juice up to TID; • macrogol, 13.125 g/dose, 1–2/day; • lactulose, 10–20 ml TID; • bisocodyl 5–15 mg at night; or • senna 2 tablets to start (7.5–8.6 mg each) TID, up to 2 tablets every 4 hours). Remember: always provide a bowel regi- men with stool softener, with or without a stimulant, to patients being treated with opioids such as morphine or codeine. 12. Management of incontinence Table 16. Management of incontinence Condition Treatment and dosages (for adults) Suggestions for home care Incontinence of urine or faeces • Assess for possible neurological reasons (cerebral toxoplasmosis or other opportunistic infections (OI)). • For males: use urine bottle, con- dom or catheter. • For females: consider catheteriza- tion. • In general consider diapers, regardless of patient sex. • Keep stools firm with loper- amide (see Table 13). • Change pads or diapers regularly. • Keep skin clean and dry; apply protective ointments as needed. 113 palliative care for people living with hiv 13. Management of itching Skin rashes, both mild and severe, can be a side-effect of ARV regimens; if suspected, see Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents, Table 11. Table 17. Management of itching Condition Treatment and dosages (for adults) Suggestions for home care Scabies, prurigo, eczema, ringworm, dry itchy skin, psoriasis, icterus Assess whether condition is a side-effect of medication. General care • Local steroid creams may be useful if inflammation is present in absence of infection (bacterial, fungal or viral). • Antihistamines: ° chlorpheniramine 4–5 mg BID, cetirizine 10 mg OD, hydroxy- zine 25–50 mg TID; ° diphenhydramine 25–50 mg at bedtime or up to TID, possibly useful for severe itching. • For skin infections, use 0.05% chlorhexidine rinse after bathing. • For itching from obstructive jaundice, try prednisolone (20 mg OD) or haloperidol (2 x 1 mg OD). • For eczema, gently wash with warm water and dry skin. Do not use soap. Topical steroids may be used for the short term (but not on face). • For ringworm, use compound benzoic and salicylic acid oint- ment (Whitfield ointment) or other antifungal cream. If extensive, use fluconazole (start with 200 mg on first day, followed by 100 mg OD). • Consider treatment for scabies even if there are no typical lesions (ivermec- tine 200 µg x 1 dose; see Protocol 2, Management of opportunistic infec- tions and general symptoms of HIV/ AIDS, section on General symptoms, scabies.) • For psoriasis, use coal tar ointment 5% in 2% salicylic acid and expose to sunlight 30–60 minutes per day. Try any of the following: • applying petroleum jelly to the itchy area; • putting one spoon of vegetable oil in 5 litres of water to wash the patient; • diluting one teaspoon of chlorhexi- dine in a litre of water and applying after bathing; or • using warm water for bathing. Seek help from a trained heath worker for painful blisters or extensive skin infection. 114 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 14. Management of bedsores Table 18. Management of bedsores Condition Treatment and dosages (for adults) Suggestions for home care Signs of infection All patients need skin care to avoid pres- sure sores. • Ensure infection is not from another source. • If redness, tenderness, warmth, pus or crusts present, assess for fever; if systemically unwell, or if infection extends to muscle, refer to hospi- tal, start IV/IM antibiotics (or oral cephalexin or dicloxacillin). • Start cephalexin or dicloxacillin 500/1000 mg four times daily (QID) if any of the following present: ° lesion greater than 4 cm ° red streaks ° tender nodes ° more than 6 abscesses. • Drain pus if fluctuant, elevate limb and follow up next day. • If sores are only red, tender and warm, clean them with antiseptic, drain pus if fluctuant and follow up in two days. • For ill-smelling tumours or ulcers use crushed metronidazole to cover the affected area. Soothing the pain of bedsores and has- tening their healing • For small sores, clean gently with salty water and allow to dry. • For bedsores that are not deep, leave the wound open to the air. • If painful, give painkillers such as paracetamol or aspirin regularly. • For deep or large sores, gently clean and cover with clean light dressing daily to encourage healing. • Seek help from a trained health worker for any discoloured skin, or if bedsores worsen. Preventing bedsores in bedridden PLHIV • Help the patient to sit up in a chair from time to time if possible. • Lift patient up in the bed – do not drag patient, as it can break the skin. • Change the patient’s position on the bed often, if possible every 1–2 hours – use pillows or cushions to maintain position. • After bathing, dry skin gently with a soft towel. • Oil the skin with cream, body oil, lanolin or vegetable oil. • Massage back, hips, elbows and ankles with petroleum jelly. • If there is leakage of urine or stools, protect the skin with petroleum jelly applied around the genital area, back, hips, ankles and elbows. • When passing urine or stool in bed, the patient should be supported over the receptacle so as to avoid injury and soiling of linen. Bedding suggestions • Keep bedding clean and dry. • Put extra soft material, such as a soft cotton towel, under the patient. • For incontinent PLHIV, use plastic sheets under the bed sheets to keep the mattress dry. 115 palliative care for people living with hiv 15. Management of mental health problems For individuals living with HIV, attention to and care of mental health is of particular significance. For example, studies suggest that people living with HIV who suffer from depression have low- er levels of adherence to HIV medication. On the other hand, antidepressant treatment improves adherence to antiretroviral treatment among depressed PLHIV (35). Mental health issues in PLHIV may arise independently of HIV as part of an associated illness (organic cause), or as a reaction to the HIV diagnosis or related stressors and social issues, such as stigmatization and health uncertainty. Anxiety disorders cover a broad spectrum. Anxiety can be non-pathological, or it can present as part of another illness, such as depression or thyrotoxicosis. In other cases, it presents as an independent entity, ranging from anxiety that is pervasive and persistent (generalized anxiety disorder, or GAD) to anxiety in specific situations, either with an identifiable source (a traumatic event or phobic entity) or without, as in panic attacks. For each type, severity may also vary from mild to severe. Table 19. Management of anxiety Condition Treatment and dosages (for adults) Suggestions for home care GAD Counsel on managing anxiety in accord- ance with the specific situation, teach relaxation techniques, listen carefully and provide emotional support. Self-help based on cognitive behav- ioural therapy (CBT) principles should be encouraged, or a CBT referral made if available. CBT involves a short course of sessions with a psychologist or psychia- trist to explore the origins and warning signs of depression and learn skills to manage it. A selective serotonin reuptake inhibi- tor (SSRI) is an appropriate first-line pharmacological treatment, e.g. citalo- pram 10 mg OD for the first week, increasing to 20 mg or higher (max. 60 mg/day) for several weeks. A benzodiazepine can provide rapid symptomatic relief from anxiety but because of tolerance and dependence should not be used beyond 2–4 weeks. It may be useful at the start of SSRI treat- ment to prevent an initial worsening of symptoms. Helping with anxieties • Take time to listen to the patient. • Discuss the problem in confidence. • Soft music or massage may help the patient to relax. • Connect the patient with appropriate support groups. • In case of increasing anxiety or depression, refer to a health care provider. Panic disorder An SSRI should be used as a first-line treatment. If the SSRI is contraindicated or ineffec- tive, clomipramine can be used (25 mg OD to start, increased over 2 weeks to daily dose 100–150 mg) Self-help based on CBT principles should be encouraged, with referral for CBT if available. Phobic disorders An SSRI may be begun. CBT is par- ticularly important, for example, using graded exposure techniques. 116 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 16. Management of sleeping problems Insomnias are disorders in initiating or maintaining sleep. They may be divided into initial insom- nia, middle insomnia and early-morning wakening. In many cases the insomnia is a symptom of another mental or physical disorder, such as: • unmanaged pain • anxiety • depression • drug withdrawal (e.g. from alcohol, diazepam or heroin). Insomnia, nightmares and somnolence can all be side-effects of certain ARV regimens, especially those with efavirenz; if suspected, see Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents, Table 11. Table 20. Management of insomnia Condition Treatment and dosages (for adults) Suggestions for home care Insomnia Ascertain whether the underlying cause of insomnia has been addressed, e.g. depression, anxiety, mania, pain or sub- stance withdrawal. In the absence of such causes, better sleep hygiene should be considered. • Exercise in the daytime, use relaxa- tion techniques such as meditation or listening to calming music, and ob- serve a routine of retiring and rising at the same time each day. • Daytime napping and using the bed for daytime activities should be discouraged and caffeine and alcohol intake reduced, especially at night- time. For initial insomnia, getting up after 20 minutes and engaging in a relaxing activity before returning to bed may be recommended. In some individuals, short term use of a benzodiazepine (e.g. temazepam 5–10 mg at night) or another hypnotic (such as 3.75–7.5 mg zopiclone) can be taken at least one hour before retiring. Either one can be continued for a maximum of 3–4 weeks, to avoid tolerance and depen- dence. Longer term treatment may be beneficial in a small number of cases, but may cause rebound insomnia; hypnotics should be tapered slowly. Listen to the fears that may be keeping the patient wake, and respond to these fears in a reassuring manner. Reduce noise where possible. Do not give the patient strong tea or cof- fee late in the evening. Treat pain if present. 17. Management of affective disorders 17.1. Depression Symptoms of depression include: • low moods, reduced energy, decreased activity and diminished capacity for enjoyment; • reduced interests and concentration, and marked tiredness after even minimum effort; • disturbed sleep and diminished appetite; and • reduced sense of self-esteem and self-confidence (even in mild depression), often with some feelings of guilt or worthlessness. 117 palliative care for people living with hiv The lowered mood varies little from day to day, is unresponsive to circumstances and may be ac- companied by so-called “somatic” symptoms, such as early-morning awakening, marked psycho- motor retardation, agitation, loss of appetite, weight loss and loss of libido. Table 21. Management of depression Condition Treatment and dosages (for adults) Suggestions for home care Depression (general) Assess and classify as to suicide risk, major or minor depression, complica- tions from loss or other difficult life events. • Consult with a psychiatrist for treat- ment • Consider whether the condition may be due to effects of medication, e.g. efavirenz; see Protocol 1, Patient evaluation and antiretroviral treat- ment for adults and adolescents, Table 11. Provide support and counselling. Mobilize family and friends for sup- port, and refer patient to PLHIV support groups or religious support groups. Do not leave alone if suicide risk: • counsel; • help patient find a solution if sleep- disturbed; and • follow up. Mild depressive episode Symptoms from two or three of the symptom groups listed in the text are usually present. The patient is usu- ally distressed by them but is probably able to continue with most activities. Antidepressants are not recommended, as monitoring, problem-solving and exercise are more important. — Moderate depressive epi- sode Symptoms from all four groups listed in the text are usually present, and the patient is likely to have great difficulty in continuing with ordinary activities. For a single moderate episode of de- pression, it is advised that treatment be continued for 4–6 months; longer for multiple episodes. First-line treatment should be an SSRI, e.g. citalopram 10–20 mg/d, increas- ing with monitoring over several weeks to a maximum of 60 mg/d. The lowest possible therapeutic dose should always be used. In the early stages of SSRI use, the patient should be closely monitored for restlessness, agitation and suicidal ten- dencies. Many PLHIV find the potential side-effect of reduced libido unaccept- able. — Second-line therapy should be con- sidered if SSRI is poorly tolerated or ineffective after 6–8 weeks. An antide- pressant from another class (usually a tricylic or an MAO inhibitor, e.g. ami- tryptyline initially 25 mg TID) can then be used, with reference to a standard text for guidelines on withdrawing or substituting. However, it must be borne in mind that tricylics are very toxic in overdose, so they should not be consid- ered if there is a risk of self-harm. An alternative SSRI could also be tried, e.g. sertraline commencing at 50 mg daily. Caution: The herbal antidepressant St John’s wort interacts with PIs and NNRTIs, leading to low levels of these drugs in the blood and risking the devel- opment of drug-resistant HIV. It is thus not recommended for patients taking PIs or NNRTIs. 118 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Condition Treatment and dosages (for adults) Suggestions for home care Severe depressive episode without psychotic symptoms Several of the above symp- toms are marked and dis- tressing, typically loss of self-esteem and feelings of worthlessness or guilt. Suicidal thoughts and acts are common, and several “so- matic” symptoms are usually present. For severe or resistant depression, a combination of antidepressants and CBT is recommended. Depending on the severity of the depression and the risk to the patient, a mental health specialist may consider lithium (enough to achieve a plasma level of 0.4–1.0 mmol/litre), electrocon- vulsive therapy or venlafaxine (start- ing dose 75 mg/day), with appropriate advice to the patient, including baseline tests: a minimum of electrocardiogram (ECG), thyroid and renal function for lithium, and ECG and blood pressure for venlafaxine. Educate patient and family about medica- tion. Refer for counselling. Ensure follow-up. Severe depressive episode with psychotic symptoms A severe episode of depres- sion with hallucinations, delu- sions, psychomotor retarda- tion or stupor. Psychotic symptoms may require com- mencement of an antipsychotic, follow- ing review by a mental health specialist. — Suicidal thoughts Assess if the person has a plan and the means to carry out suicide. If so, con- sider patient to be high risk and refer for hospitalization. Do not leave alone. Remove harmful objects. Mobilize family and friends. 17.2. Mania and bipolar affective disorder (BPAD) • Individuals with HIV may suffer comorbidly from BPAD, which is characterized by two or more episodes of mood disturbance, including one that is manic or hypomanic. • Mania has been documented as occasionally presenting in individuals with no personal or fam- ily history of BPAD, but with advanced HIV or very low CD4 counts. Typical signs of mania and BPAD: • Mood is elevated out of keeping with the patient’s circumstances and may vary from carefree joviality to almost uncontrollable excitement. • Elation is accompanied by increased energy, resulting in overactivity, pressure of speech and a decreased need for sleep. There is often marked distractibility. Self-esteem is often inflated with grandiose ideas and overconfidence. • Loss of normal social inhibitions may result in behaviour that is out of character as well as reck- less or inappropriate. • In addition, delusions (often grandiose) or hallucinations may be present. 119 palliative care for people living with hiv Table 22. Management of mania and BpaD Condition Treatment and dosages (for adults) Suggestions for home care Mania and BPAD Mood stabilizers – including lithium (plasma level 0.4–1.0 mmol/litre), valproate semisodium, lamotrigine and gabapentin – can be used with caution. Valproate semisodium is an enzyme inhibitor, so that as with most psycho- tropics to varying degrees, its potential effect on ARV levels should be consid- ered when starting or stopping valproate semisodium. Caution: carbamazepine should gener- ally not be used because of interactions with ARVs and risk of agranulocytosis. CBT can also play an important role in helping provide the patient with the skills to recognize the warning signs and trig- gers of mood swings. Psychotic symptoms may require com- mencement of an antipsychotic, follow- ing review by a mental health specialist. Caregivers can help with medication compliance and identification of early warning signs of mood disorders. 18. Management of dementia Dementia is a syndrome due to brain disease, usually of a chronic or progressive nature, in which there is disturbance of multiple higher cortical functions, including memory, thinking, orientation, comprehension, calculation, learning capacity, language and judgement. It should be noted with dementia that: • consciousness is not clouded; and • impairments of cognitive function are commonly accompanied, and occasionally preceded, by deterioration in emotional control, social behaviour (e.g. disinhibition) or motivation. Individuals with HIV may also present with cognitive impairment or apparent dementia for other reasons. • Depression and anxiety can present with forgetfulness and concentration difficulties, so should be excluded from a diagnosis of dementia. • Acute infection may also present with confusion (delirium), and should also be excluded. • In addition, some people with advanced HIV and very low CD4 counts may present with cogni- tive impairment that is thought to be due to the effects of HIV on the CNS, or possibly to the immune response to the virus. 120 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Table 23. Management of dementia Condition Treatment and dosages (for adults) Suggestions for home care Dementia Dementia with behavioural changes such as aggression or restlessness • Assess for alternative explanations, such as depression and delirium. • Assess for reversible causes of dementia, such as normal pressure hydrocephalus, operable tumours, hypothyroidism, neurosyphilis and vitamin B12 and folate deficiencies. Treat accordingly. • Consider pain or fear as possible causes, and treat accordingly. • The mainstay of treatment for HIV- associated dementia is HAART. Non-pharmacological strategies are preferable, such as attempts to commu- nicate patiently. Medication may also be considered, e.g. low dose quetiapine (12.5 mg daily), if the patient is dis- tressed. When the patient is being cared for at home, carer support, including relief for the caregiver, should be offered where resources allow. Reducing rest- lessness may also be more critical in the home environment, since the family may be adversely affected by this behaviour over time. As far as possible, keep patient in a familiar environment. • Keep things in the same place, easy to reach and see. • Keep a familiar pattern to the day’s activities. • Remove dangerous objects. • Speak in simple sentences, one per- son at a time. • Keep noise down. • Make sure somebody is always present to look after the patient. Paranoia, severe agitation or distress at night Distress, particularly if patient is experiencing paranoid delusions or other psychotic symptoms Again, non-pharmacological strategies are preferable, such as attempts to com- municate patiently. Medication may be considered, e.g. low dose quetiapine (12.5 mg daily), if the patient is dis- tressed, following careful psychiatric assessment of the nature of the patient’s symptoms and experiences. Due attention should be given to the increased risk of falls if medication is given. 19. Management of cough or difficulty breathing Cough or difficulty breathing may be due to common opportunistic infections seen in HIV/AIDS or to immune reconstitution syndrome, which is usually seen within two to three months of starting ART. If the latter is suspected, see Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents, section on immune reconstitution syndrome. 121 palliative care for people living with hiv Table 24. Management of cough or difficulty breathing Condition Treatment and dosages (for adults) Suggestions for home care Dyspnoea with broncho- spasm Give oxygen via mask if possible. Asthma protocols • Give bronchodilators by metered- dose inhaler with spacer/mask or nebulizer. Continue until patient is not able to use them or has very shal- low or laboured breathing. • Give prednisolone 1 mg/kg per day (usually 60 mg in one dose in the morning); wait one week to assess response, than slowly reduce by 10 mg over a week. For simple cough • Use local soothing remedies, such as honey, lemon or steam (plain or with eucalyptus). • If patient has a new productive cough for more than two weeks, it may be tuberculosis. Arrange with health worker to send three sputum samples for examination for TB. In addition to treatment given by a health worker • Help the patient into the best position to ease breathing – usually sitting up. • Leaning slightly forward and resting arms on a table may help. • Use extra pillows or some back sup- port. • Open windows to allow in fresh air. • Fan with a newspaper or clean cloth. • Give patient water frequently to loosen sputum. For safe handling and disposal of sputum • Handle with care to avoid spreading infection. • Use a tin for spitting and cover it. • Empty the container in the toilet and wash the tin with a detergent or clean with boiled water. For easing use of remaining lung func- tion • Plan activities to accommodate breathlessness. • Avoid crowding, cooking and smok- ing in the patient’s room. Heart failure or excess fluid Furosemide 40–160 mg/day in a single or divided dose until symptoms improve (monitor for overdiuresis) Cough with thick sputum • Administer nebulized saline. • If more than 30 ml/day, try expiratory technique (“huffing”) with postural drainage. • Avoid tracheal suction, which is very distressing to the patient. Excessive thin sputum Hyoscine (make use of its anticholiner- gic side-effect) 10 mg every 8 hours Pleural effusion (due to Kaposi sarcoma, pneumo- nia, etc.) Aspirate pleural fluid if possible (see also Protocol 2, Management of opportunis- tic infections and general symptoms of HIV/AIDS). Dry cough Codeine 5–10 mg QID or, if no response, oral morphine (2.5–5 mg) as long as needed (try to reduce after one week) New productive cough more than 2 weeks TB • Send three sputum samples for acid- fast bacilli (AFB) testing. • See Protocol 4, Management of tuberculosis and HIV coinfection. • Continue treatment to prevent trans- mission. Dyspnoea in terminal patients • Oral morphine/tramadol in small dose. • For patients not already on oral morphine for pain, give 2.5 mg every 6 hours; if no relief increase dose progressively by clinical measures; treat pain and anxiety. • For patients already on oral mor- phine, increase dose progressively by 25%. 122 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 20. Prevention of contractures and stiffness Table 25. prevention of contractures and stiffness Condition Treatment and dosages (for adults) Suggestions for home care Stiffness and contractures Muscle spasms Diazepam 5–10 mg 2–3 times daily Tetrazepam 50 mg/day, up to 200 mg/ day in 2 doses Baclofen starting 5 mg TID, increasing every 3 days up to 25 mg TID Do not confine – encourage mobility. Do the following simple range-of-motion exercises if patient is immobile. • Exercise limbs and joints at least twice daily. • Protect joints by holding the limb above and below and support it as much as possible. • Bend, straighten and move joints as far as they normally go. Be gentle and move slowly without causing pain. • Stretch joints by holding as before but with firm steady pressure. • Bring the arms above the head and lift the legs to 90 degrees – let the patient do it as far as possible and help the rest of the way. Massage the patient. 21. Management of vaginal discharge from cervical cancer Table 26. Management of vaginal discharge from cervical cancer Condition Treatment and dosages (for adults) Suggestions for home care Vaginal discharge from cervical cancer Metronidazole 100 mg tablets as pessary OD Provide daily hygiene. Patient can sit in basin of water with pinch of salt, twice daily if possible. 22. Drug interaction considerations There are a few instances in which medications used in palliative care are not recommended for use with antiretroviral agents such as the more potent PIs (e.g. ritonavir and indinavir) or NNRTIs (e.g. nevirapine and efavirenz), due to drug interactions mediated through the cytochrome P450 enzyme system involved in hepatic metabolism. These substances to avoid include triazolam, midazolam, terfenadine, astemizole and St John’s wort (36–40). In most other cases, such as longer-acting ben- zodiazepines, anticonvulsants and tricyclic antidepressants, it is recommended rather that clinicians monitor patients closely for evidence of under- or overmedication, and that therapeutic drug level monitoring be used in instances where it is available and may provide useful additional informa- tion. 123 palliative care for people living with hiv V. Special advice for terminal care It is very helpful in the care of dying patients for family members to understand and anticipate some of the medical, emotional and spiritual changes that can occur as part of the normal process of dying in the last months of life. The health care team can play an important role in educating fam- ily members and other caregivers about end-of-life issues, including what to expect over the final course of the illness. At the end of this section, Table 27 presents a general prognostic timeframe for approaching the end of life, describing typical patient features and interventions that may be help- ful in the last months, weeks, days and hours of life. General recommendations for working with patients’ families in end-of-life care are presented immediately below. 1. Preparing for death • Encourage communication within the family. A family meeting may be useful to identify the fears and worries and of the patient and of the family. • Talking with the patient to establish the patient’s understanding and prognosis of the disease is important. • Discuss worrisome issues such as custody of children, family support, future school fees, old quarrels and funeral costs. • Let the patient know he/she will be loved and remembered. • Talk about death if the person so wishes. Find out if the patient has ever seen anyone die and his or her own fears about death. Such fears may have a basis in physical and/or psychological ones. • Make sure the patient gets help in addressing any feelings of guilt or regret. • Respond to spiritual needs as the patient requests, providing connections with spiritual counsel- lors or religious institutions of the patient’s choice. 2. Presence • Be present with compassion. • Visit regularly, hold hands, listen and talk. 3. Caring Provide comfort measures, such as: • moistening lips, mouth and eyes • keeping patient clean and dry • treating fever and pain (around the clock if necessary) • controlling other symptoms and relieving suffering with medical treatment as needed • providing liquids and small amounts of food as needed • providing physical contact. 4. Bereavement After the death of the patient, it is important to acknowledge and attend to the bereavement needs of survivors. Particular issues for families affected by HIV include: • the relatively young age at which most patients die, which can be a more difficult loss for fami- lies than the death of an older family member; • the immediate and longer term risk of financial and social losses; • the stigmatized nature of the disease, which may complicate the grieving process; and • the possibility that other family members have already have died from HIV/AIDS, or that sur- vivors may be HIV-infected and at risk for dying from it. 124 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION All of these issues make it necessary for HIV/AIDS care providers to be sensitive and responsive to the needs of survivors and orphans to help them deal with the grief and multiple losses which HIV/AIDS often inflicts on families. 125 palliative care for people living with hiv Ta bl e 27 . co m m o n m an if es ta ti o ns in p lh iv a pp ro ac hi ng t he e nd o f li fe , a nd s ug ge st io ns f o r fa m ily a nd c ar eg iv er s up po rt Ty pe of m an ife sta tio n La st mo nt hs L as t w ee ks La st da ys La st 24 –2 8 h ou rs PL HI V en d-o f-l ife m an ife sta tio ns Ph ys ica l • Inc rea sed fa tig ue • Inc rea sed sl ee p • De cre ase d i nte res t in ea tin g • Inc rea se in pa in or oth er sy mp - tom s • M ore tim e i n b ed • Ins om nia • Le ss int ere st in foo d a nd dr ink • De cre ase d e ne rgy • D if fi cu lt y w al ki ng • Inc on tin en ce • Sle ep pa tte rn rev ers al • Sw ea ts • Co nfu sio n • Co gn itiv e f ail ure • Ch an ge s i n s kin (p all or) • Re sp ira tor y c ha ng es • So mn ole nc e • Re stl ess ne ss • Ag ita tio n • Gr ad ua l o r s ud de n l os s o f c on - sci ou sn ess • Fu rth er ch an ge s i n s kin co lou r • Pe rio dic br ea thi ng • Gu rgl ing • M oa nin g • De lir ium Em oti on al • Inc rea sed ne ed fo r c los en ess , tal kin g, ph ys ica l c on tac t • So cia l w ith dra wa l • Inc rea sed sa dn ess , c ryi ng • Se ek ing cl os ure , e xp res sin g f ee l- ing s o f l ov e • De sir e t o t alk ab ou t f un era l a r- ran ge me nts • Pe rio ds of in ten se em oti on al ex - pre ssi on • Ba rga ini ng • Li fe rev iew , d isc us sio n o f p ast ev en ts • De sir e t o r ea ssu re fam ily • Fe ar of sle ep • Gr ea ter pe ac efu lne ss, qu iet • Inc rea sed co mm un ica tio n • Sig ns of cl os ure /sa yin g go od by e • Inc rea sed an xie ty • M ay be un res po ns ive or m ini ma lly res po ns ive • Co nfu sio n, de lir ium , in ab ilit y t o ex pre ss em oti on s c lea rly Sp iri tu al • Inc rea sed in ter est in sp iri tua l ma tte rs • Pr ay er • De sir e f or co nta ct wi th rel igi ou s/ sp iri tua l le ad er • Qu est ion ing of fa ith • Dr ea ms or vi sio ns of de ce ase d lov ed on es • Inc rea sed fa ith in G od • P er io ds o f qu ie t r efl ec ti on • Inc rea sed cl ari ty in thi nk ing an d e mo tio ns • Inc rea sed se ns e o f p ea ce an d tra ns ce nd en ce • Pe rce pti on of ot he r d im en sio ns of ex pe rie nc e • Inc rea sed se ns e o f p ea ce • De ep pe ac efu l s lee p 126 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Ty pe of m an ife sta tio n La st mo nt hs L as t w ee ks La st da ys La st 24 –2 8 h ou rs Su gg est ion s f or fa mi ly/ ca reg ive r s up po rt Al l • Al low pa tie nt to dic tat e f oo d pre fer en ce s. • O ff er a nd e nc ou ra ge f oo d/ fl ui ds (ne ve r p res su re or for ce ). • Of fer as sis tan ce w ith w alk ing . • He lp cre ate a co mf ort ab le, sa fe en vir on me nt. • W ork cl os ely w ith tr ea tm en t tea m an d r ep ort an y n ew or wo rse nin g s ym pto ms or pr ob - lem s. • Pr ov ide em oti on al su pp ort ;

Suggested minimum data to be collected at the clinical level The suggested minimum data to be collected is important in the development of key indicators on access to palliative care and its success. Such indicators assist managers in decision making on ways to strengthen and expand these services to all PLHIV who need them. The following data should be collected on a regular basis (e.g. monthly, quarterly or semi-annually): • number of HIV/AIDS patients requiring palliative care2 • number of HIV/AIDS patients receiving palliative care • number of HIV/AIDS patients receiving any pain management • number of HIV/AIDS patients receiving opioid pain management 2 Defined as the PLHIV who exhibit the signs and symptoms described in this protocol. 128 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Annex 1.

Epidemiology of TB, TB/HIV/AIDS and reciprocal influence of TB and HIV 1. Epidemiology of TB Tuberculosis (TB) is a serious public health problem in the WHO European Region, where accord- ing to the most recent WHO estimates, almost 445 000 new cases and more than 69 000 related deaths occurred in 2004. The overall TB incidence rate for the Region is 50 per 100 000 popula- tion, ranging nationally from 2/100 000 in Monaco to 177/100 000 in Tajikistan. By subregion, the rates are 12/100 000 for western Europe, 27/100 000 for central Europe and 96/100 000 for eastern Europe. Among the 22 high-burden TB countries in the world, the Russian Federation ranks 12th (1, 2). As noted, the highest rates of TB are reported in the countries of eastern Europe, where weakened economies and public health efforts are the main causes of its resurgence, and where internation- ally recommended control strategies need further expansion and strengthening. In western Europe, there are pockets of increasing incidence, particularly in major cities with socially marginalized immigrants from high-burden TB countries (3, 4). The European Region has the highest prevalence rates in the world for multidrug-resistant TB (MDR-TB); it includes seven of the nine countries in the world with >6.5% prevalence of MDR- TB in new cases (Estonia, Israel, Kazakhstan, Latvia, Lithuania, the Russian Federation and Uz- bekistan), as well as five of the nine countries with >30% prevalence of MDR-TB in previously treated cases (Estonia, Kazakhstan, Lithuania, the Russian Federation and Uzbekistan) (5). TB is more frequently found among prisoners than in the outside population. The average prison population rate in the European Region is about 100 prisoners per 100 000 inhabitants, with higher rates in the eastern part of the Region. In the Russian Federation, the 2003 rate was approximately 600/100 000 (6). In 2003, more than 7% of the new TB cases reported to WHO Regional Office for Europe were detected in prisons, with large variations among countries (range 0.1–30.4%) (7–10). 2. Epidemiology of TB/HIV coinfection In eastern Europe there are independent epidemics of TB and HIV/AIDS, and a large majority of TB patients developed their disease without HIV-related immunosuppression. Among people living with HIV (PLHIV), the risk of acquiring TB is higher where the TB prevalence is high. In 2004, western and eastern European countries reported TB as the most frequent AIDS-indicative disease, with respective rates of 24% and 56% of newly reported AIDS cases (11, 12). Unfortunately, knowl- edge of the real extent of TB/HIV coinfection in Europe is limited due to insufficient surveillance data. As the result of the recent dramatic increase of HIV prevalence in eastern Europe, as well as the high prevalence of TB there, it is expected that the number of TB/HIV patients will dramatically increase in the next few years (12–14). Prisoners are more vulnerable to becoming infected with TB and HIV due to environmental and nu- tritional factors that increase their exposure, vulnerability and risk-taking behaviour. Prisons, with their often crowded and enclosed conditions, poor ventilation, inadequate lighting and continuous exposure to TB-infected people, facilitate airborne TB transmission. Malnutrition also contributes to the higher risk for prison transmission. In addition, common prison behaviours – unsafe inject- ing drug practices, tattooing and unprotected sex – expose prisoners to HIV infection, as well as hepatitis B and C (15). 136 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 3. Reciprocal influence of HIV and TB 3.1. Influence of HIV on the development of active TB HIV promotes the progression of infection with Mycobacterium tuberculosis to active TB, both in people with recently acquired infections and those with latent infections. Undeniably, HIV is the most powerful risk factor known for activation of latent M. tuberculosis infection. For an HIV-in- fected person-coinfected with M. tuberculosis, the risk of developing active TB reaches 5–10% an- nually, instead of the 5–10% lifetime risk for an individual not infected with HIV. This discrepancy is clearly linked to the immunodeficiency caused by HIV. Furthermore, HIV infection increases the rate of recurrent TB, which can be due to either endogenous reactivation or exogenous reinfection (16, 17). 3.2. Influence of HIV on the transmission of TB TB is one of the most common infections in HIV-infected people, especially in high TB prevalence areas. HIV greatly increases the number of TB patients, which in turn increases TB transmission from family members (the highest TB transmission risk is from household contacts, such as chil- dren and HIV-positive partners) and community members (through contact in work-places, schools and hospitals) where there is a risk of nosocomial infections from both patients (whether HIV-posi- tive or -negative) and health care workers. Moreover, the risk of MDR-TB transmission may be increased if effective and uninterrupted TB treatment is not ensured (18–20). 3.3. Influence of HIV on the clinical presentation of TB As HIV infection progresses, CD4 lymphocytes decline by about 50–80 cells/mm3/year, and the im- mune system becomes less able to prevent the growth and local spread of M. tuberculosis. Pulmonary TB (PTB) remains, especially in adults, the commonest form of TB, but its presentation depends on the degree of immunosuppression. The clinical pictures, sputum-smear results and chest X-rays are often different in the early stage of HIV infection (CD4 >350 cells/mm3) and the late stage (CD4 <200 cells/mm3). The clinical presentation of TB cases in early HIV infection is similar to that of individuals without HIV infection, resembling post-primary PTB, that is, with positive sputum smears (defined as two or more initial smear examinations that are positive for acid-fast bacilli (AFB), or one plus consistent radiographic abnormalities) and often with cavities in the chest X-ray. In contrast, the clinical presentation in late HIV cases resembles primary PTB: the sputum smear is often negative and radiological infiltrates are present instead of cavities (21–23). In case of severe immunodeficiency, the rate of extrapulmonary TB (EPTB) increases in both adults and children. Because of difficulties in diagnosis, disseminated TB may account for a high proportion of misattributed hospital deaths. 3.4. Influence of TB on HIV morbidity and mortality Active TB itself is responsible for a mild immune deficiency. In countries with independent epidem- ics of TB and HIV/AIDS, TB does not always indicate severe deterioration of the immune system in HIV-infected people because it may occur before HIV infection or in its early stages, before the im- mune system has deteriorated. When active TB occurs in HIV patients, a worsening of the HIV-re- lated deficiency is commonly observed, facilitating the progression of other opportunistic infections such as Candida albicans oesophagitis, Cryptococcus meningitis and, particularly, Pneumocystis jirovecii (formerly P. carinii) pneumonia. Any of these opportunistic infections may be lethal. If so, TB is indirectly responsible for the death (24). In addition, TB has been found directly responsible for an average mortality rate of 30% among HIV/AIDS cases in many reports (22, 23, 25). These data emphasize the need of early diagnosis and specific treatment of TB in all HIV-infected patients, especially when the clinical pattern of CD4 cells count shows a severe degree of immunodeficiency. 137 ManageMent of tuberculosis and HiV coinfection II. Identification of TB/HIV in adults and adolescents All HIV-positive people should be assessed for risk factors for having or acquiring TB, just as all patients with active TB disease should be offered HIV testing and counselling. The major reasons for this are: • HIV-positive people are at higher risk for having or developing active TB, one of the major op- portunistic infections causing death in PLHIV; • HIV infection influences the clinical progression of TB and its treatment; • TB disease influences the clinical progression of HIV/AIDS and its treatment; and • TB may be an indicative sign of advanced HIV/AIDS disease. 1. TB risk assessment and diagnosis in PLHIV In assessing PLHIV for TB risk, particular attention should be paid to: • people with respiratory symptoms; • household contacts of anyone with an active case of pulmonary TB; and • coexisting risk factors and vulnerability-increasing factors (e.g. injecting drug use, alcohol abuse and incarceration). The initial assessment for TB should include: • a history of TB exposure (individual and household); and • a history of possibly related symptoms (especially a cough of more than two weeks duration without any clear explanation). If an HIV-infected person does not have an obvious risk for TB (recent exposure or clinical symp- toms), a tuberculin skin test1 should be performed to identify the status of any latent TB infection that may evolve into TB disease due to HIV-related immunosuppression. (See Fig. 1 below.) A positive tuberculin skin test is indicative of past or recent TB infection, which is a condition for starting TB preventive treatment (TPT). A negative tuberculin skin test in PLHIV usually means no risk of TB (except in those with severe immunosuppression). If an HIV-infected person has been recently exposed to TB or has clinical symptoms indicative of pulmonary or extrapulmonary TB disease, the status of active TB disease should be explored. Ac- tive TB can be excluded through careful clinical examination, bacteriological investigation (sputum microscopy and culture) and X-ray. In case of infiltrate in the chest X-ray, a clinical trial with a full course of broad-spectrum antibiotics may be necessary to make a diagnosis differentiating between TB and nonspecific pneumonia. When active TB disease is excluded, the possibility of latent TB infection should be explored through a tuberculin skin test. If an HIV-infected person has active TB disease, he or she should be treated as described in section III below. 1 Tuberculin is a purified protein derived from tubercle bacilli. Tuberculin injected into the skin of a TB-infected person pro- duces a delayed local reaction after 24 to 48 hours, which is quantified by measuring the diameter of the related skin induration (thickening). The test is usually considered positive in HIV-infected people when induration exceeds 5 mm. The reaction only shows that the person has at some time been infected with M. tuberculosis (15, 17). 138 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Fig. 1. algorithm for assessing tb risk and disease in an HiV-positive person Recent TB exposure or TB symptoms Yes No Exclusion or confirmation of active TB (clinical examination, sputum-smear microscopy, X-ray, trial with a broad-spectrum antibiotic) Active TB Active TB excluded TB treatment Tuberculin skin test Positive Negative TB preventive treatment 2. HIV risk assessment and diagnosis in patients with TB Offering HIV testing and counselling should be a routine procedure in health care settings dealing with patients who have active TB. Health care providers should explain to the patients the reasons for offering the test and the importance of knowing the results for correct clinical management. However, all patients have the right to refuse an HIV test. The initial assessment of a patient’s HIV status should include: • HIV pretest counselling; • serological tests (typically, ELISA and/or rapid tests) for HIV antibodies, followed by a western blot confirmatory test; and • post-test counselling, including information on reducing risky behaviour, irrespective of the re- sults of the HIV test. Further evaluation of patients found to be HIV-infected is required to decide on a clinical manage- ment strategy. For more detailed information, see Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents. 139 ManageMent of tuberculosis and HiV coinfection III. Clinical management of TB/HIV in adults and adolescents For clinical management of TB/HIV-coinfected patients, a major consideration is when to start treatment. After initial assessment of TB and HIV status, a patient with TB/HIV would fit in one of two TB categories, each requiring a different clinical management strategy, and each of which may or may not require ART: 1. TB-infection (positive tuberculin skin test) 2. active TB disease. 1. Management of coinfected patients HIV-infected patients coinfected with TB have a higher risk of developing active TB; therefore, tuberculosis preventive treatment (TPT) should be initiated with isoniazid 5 mg/kg (300 mg maxi- mum) once daily (OD) for six months. Alternative schedules have been suggested to improve adherence, but further research is needed to prove their efficacy. Further research is also needed for developing alternative TPT in areas with high prevalence of isoniazid resistance (26–28). The addition of 6 mg pyridoxine daily can prevent peripheral neuropathy, especially in pregnant women, alcoholics and the malnourished. The decision of when to start ART is based on a number of indicators, of which the most important are the HIV/AIDS clinical stage and immunological criteria (please refer to the section on Initia- tion of HAART and WHO Clinical staging of HIV/AIDS for adults and adolescents, in Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents). TPT can also be given simultaneously with ART. More evidence is required to identify the threshold of CD4 count above which TPT can be considered less necessary. 2. Management of coinfected patients with active TB 2.1. TB treatment TB treatment in HIV-infected patients is a priority and should be started as soon as active TB has been diagnosed. Treating TB promptly will reduce TB-related mortality and the risk of transmission (15, 29, 30). Treatment of TB, regardless of its concomitance with ART, should be based on drugs of known bio- availability. TB treatment regimens consist of two phases: an initial phase and a continuation phase. Each TB drug has an abbreviation (ethambutol: E, isoniazid: H, pyrazinamide: Z, rifampicin: R, streptomycin: S); for further information on drug dosages see Annex 1. The duration of the initial phase is 2–3 months, the continuation phase, 4–5 months. Present evidence clearly shows that TB relapse in HIV-infected patients is minimized by a regimen containing rifampicin throughout the course of treatment. 140 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Table 1. recommended tb treatment regimens for PlHiV with active tb Type of TB case TB.treatment.regimena Initial phaseb Continuation phase New TB patient HRZE 2 monthsc HR 4 months Previously TB-treated patient, including: • relapse • treatment after default • treatment failured HRZES 2 months or HRZE 1 month HRE 5 months Chronic or MDR-TB cases (still sputum-positive after supervised re-treatment) A specially designed regimen, whether standard or ad hoc E: ethambutol; H: isoniazid; R: rifampicin; S: streptomycin; Z: pyrazinamide. a Daily TB treatment is recommended for HIV-positive patients with active TB. b Direct observation of drug intake is recommended during the entire course of therapy, particularly in the initial phase. c Streptomycin may be used instead of ethambutol. In meningeal TB, ethambutol should be replaced by streptomycin, which diffuses more in the meninges. d Whenever possible, drug sensitivity testing should be done to enable an individualized treatment regimen. 2.2. Initiation of antiretroviral treatment Many patients with active TB have advanced HIV disease and are therefore eligible for ART, which should not be withheld simply because a patient is receiving or is about to receive TB treatment. Nevertheless, it is preferable not to initiate treatment for HIV and TB simultaneously, and when possible to delay ART (see Table 2) (31–34). This strategy: • simplifies patient management • avoids antiretroviral (ARV) and TB drug interactions • avoids overlapping toxicities • limits risk of immune reconstitution inflammatory syndrome (IRIS) • minimizes confusion about what drugs to take when, and for which disease • increases adherence. Table 2. strategy for initiation of treatment for both tb and HiV infection Criteria TB.treatment ART Extrapulmonary TB (regardless of CD4 count) Start immediately Start ART as soon as TB treatment is tolerated (between two weeks and two months)a.Pulmonary TB CD4 <200 cells/mm3 Start immediately Pulmonary TB CD4 = 200–350 cells/mm3 Start immediately Start ART after completion of initial TB treatment phase (start earlier if severely compromised). Pulmonary TB CD4 >350 cells/mm3 Start immediately Monitor CD4 count. Consider ART if CD4 cell count drops below 350 cells/mm3. a The decision to start ART should also be based on clinical evaluation of other signs of immunodeficiency. 141 ManageMent of tuberculosis and HiV coinfection 2.3. First-line HAART regimens Highly active antiretroviral treatment (HAART) is the standard recommended ART. It includes three or in some cases more ARV drugs. The main factors to consider in selecting the best ARV regimens for TB patients are: • potency • side effects and toxicity • simplicity, to allow better adherence. ART during TB treatment requires giving special consideration to: • interactions between rifampicin and some ARVs • pill burden • the importance of high adherence • drug toxicity • the risk of immune reconstitution syndrome. Table 3. recommended first-line Haart for patients being treated for tb with rifam-picina ARV drug classes HAART regimes Preferred 2 NRTIs + 1 NNRTI ZDV (or TDF) + 3TC (or FTC) + EFVb Alternative 3 NRTIs (triple-nuke regimen) ZDV + 3TC + ABC (or TDF) a See Annex 2 for dosages b Recommended efavirenz (EFV) dose is 600 mg/day especially in patients with <60 kg body weight (35–37). Increasing the dose to 800 mg/day can be considered in patients with >60 kg body weight, though further research is needed. If EFV is not available, Nevirapine (NVP) can be used [200 mg OD for 2 weeks followed by 200 mg twice daily (BID)] with close monitor- ing of liver function and drug toxicity. [ZDV + 3TC + NVP is available in an fixed-dose combination (FDC).] 2.3.1. Key considerations for first-line regimens ZDV (or TDF) + 3TC (or FTC) + EFV (see Table 3) • No rifampicin dose adjustment is required • EFV decreases methadone levels significantly; this is important to remember for treatment of injecting drug users (IDU) on opioid substitution therapy. For further information please refer to Protocol 5, HIV/AIDS treatment and care for injecting drug users. ZDV + 3TC + ABC (or TDF) (see Table 3) • No rifampicin dose adjustment is required. • Pregnant women with TB can safely use ZDV + 3TC + ABC. For additional considerations regarding first-line ART regimens, please refer to Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents. 2.3.2. Treatment failure Response to ART is monitored by clinical symptoms, CD4 count and viral load. For further infor- mation on treatment failure criteria please refer to Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents. TB is not a criterion for treatment failure in itself and if it occurs without other evidence of immu- nodeficiency in patients on a first-line regimen, they should not be switched to a second-line regi- men. If a patient on a second-line ART develops TB during treatment, the protease inhibitor (PI) component needs to be adjusted. 142 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 2.4. Second-line HAART regimens Table 4. recommended second-line Haart for patients receiving tb treatment with rifampicin ARV drug classes HAART regimens Preferred 2 NRTIs + 2 PIs (one of them boosted) ABC + ddI + LPV/r + RTV or TDF + ddI + LPV/r + RTV Alternative 2 NRTIs + 2 PIs ABC + ddI + SQV + RTV or TDF + ddI + SQV + RTV 2.4.1. Key considerations for second-line regimens ABC (or TDF) + ddI + LPV/r + RTV (see Table 4) • If ddI is administered with TDF, its dosage should be adjusted due to toxic pancreatic and nega- tive immune effects. The recommended dose of ddI when administered with TDF (300 mg OD) is: ° 250 mg OD for patients with >60 kg body weight ° 125–200 mg OD for patients with <60 kg body weight (38, 39). • When LPV/r 400/100 mg BID is administered, RTV 300 mg BID should be added, with close monitoring of liver functions and lipid levels. ABC (or TDF) + ddI + SQV + RTV (see Table 4) • When SQV is administered, the recommended daily dosages of SQV and RTV are each 400 mg, and close monitoring of liver functions is required. • No rifampicin dosage adjustment is required with these regimens. 2.5. ARV and TB drug interactions and management • Rifampicin stimulates the activity of the hepatic cytochrome P450 (CYP) enzyme system that metabolizes NNRTIs and PIs (see Annex 2 for ARV classes). This mechanism leads to a reduc- tion in the blood levels of NNRTIs and PIs, and consequently the incomplete suppression of HIV replication and the emergence of drug resistance. Rifampicin causes up to a 75% reduction in the serum levels of PIs, thus necessitating dosage adjustment. • NNRTIs and PIs can also enhance or inhibit CYP and lead to altered blood levels of rifampicin. Therefore, when rifampicin is used concomitantly with NNRTIs and PIs, a daily regimen is pre- ferred (40–42). • The effects of rifampicin and NNRTIs and PIs on the CYP are both complex and common, but unless a definitive contraindication exists, rifampicin is the preferred TB drug. The reason is that the rate of TB relapse in HIV-positive patients becomes as low as in HIV-negative patients when treated for ≥6 months with rifampicin-containing regimens. • Rifampicin has no effect on the serum levels of nucleoside reverse transcriptase inhibitors (which are not metabolized by CYP), and no dosage adjustment of these drugs is necessary. • In patients on second-line ART, rifabutin 150 mg every other day (QOD) or 3 times/week can be used safely as an alternative to rifampicin. Rifabutin may be preferred in settings with a limited capacity to adjust PI dosage; however, it is more expensive than rifampicin. • Rifabutin should not be prescribed with unboosted SQV, but it can be used with combination of SQV with RTV. 143 ManageMent of tuberculosis and HiV coinfection 2.6. Cotrimoxazole primary prophylaxis TB/HIV-coinfected patients may die soon after the commencement of treatment if it is started at too advanced an HIV/AIDS stage. Death may be related to the progression of TB itself, but in many cases the death is related to the progression of other opportunistic infections, such as Pneumo- cystis jirovecii pneumonia (PCP) or Toxoplasma gondii encephalitis (TE) (32). Therefore, primary prophylaxis with cotrimoxazole (trimethoprim-sulfamethoxazole) is needed as prophylaxis against PCP and TE. • Patients with a CD4 count <200 cells/mm3 or who are at Clinical Stage 3 (with oropharyngeal candidiasis, for example) or Clinical Stage 4 should receive cotrimoxazole simultaneously with TB treatment (if indicated) until the CD4 cell count has stabilized for 4–6 months, or at least 3 months at >200 cells/mm3. • The recommended prophylaxis with cotrimoxazole in adults is one double-strength tablet: 160/800 mg OD. • Adherence to cotrimoxazole is critical, and direct observation of its administration, together with the administration of TB drugs, may be useful, particularly in very ill patients. For more information, please refer to Protocol 2, Management of opportunistic infections and gen- eral symptoms of HIV/AIDS, section on OI prophylaxis in HIV infected patients. 3. Clinical management of TB/HIV in special conditions 3.1. Renal failure • Isoniazid, rifampicin and pyrazinamide are either eliminated almost entirely by biliary excretion or metabolized into non-toxic compounds. These drugs can therefore be given in normal dosage to patients with renal failure. • Patients with severe renal failure should receive pyridoxine with isoniazid in order to prevent peripheral neuropathy. • Streptomycin and ethambutol, however, are excreted by the kidney. They should be given in reduced doses, and renal function should be monitored closely (creatinine level monthly). • TDF should be avoided in ARV regimens due to its known nephrotoxicity. Table 5. recommended tb regimens for patients with renal failurea Initial phase Continuation phase Preferential HRZ 2 months HR 4 months Alternative (if monitoring of renal function is possible) HRZE 2 months HR 4 months a Renal failure is defined as occurring when the creatinine level increases to 130–160 micromoles/litre. 3.2. Liver disease • Isoniazid, rifampicin and pyrazinamide are all associated with drug-induced hepatitis. • Pyrazinamide is the most hepatotoxic, followed by rifampicin. Rifampicin is less likely to cause hepatocellular damage, although it is associated with cholestatic jaundice. • Patients with liver disease should not receive pyrazinamide. Alternative TB treatment regimens are listed in Table 6. • Clinical monitoring of the liver and laboratory monitoring of liver enzymes should be performed to detect any exacerbation of the condition. They should be done on a regular basis, at a fre- quency that depends on the patient’s condition. 144 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Table 6. recommended tb regimens for patients with liver diseasea Initial phase Continuation phase Preferential SHRE 2 months HR 6 months 1st Alternative SHE 2 months HE 10 months 2nd Alternative RE 9 months – a Liver disease is defined as an alanine aminotransferase (ALT) exceeding three times the normal level, or the presence of chronic hepatitis or cirrhosis. 3.3. Women of childbearing age • Rifampicin and some ARV drugs (mainly PIs) can reduce estrogen levels, so oral contraceptives containing estrogen may not be effective. For more information on contraception choices, please refer to Protocol 9, Support for sexual and reproductive health of people living with HIV. • If effective contraception is ensured, TB/HIV-coinfected women may receive a regular TB treat- ment regimen and the same ARV regimen as men, including EFV; otherwise, EFV must be avoided. ABC is a recommended alternative to EFV. 3.4. Pregnant women • The strategy for initiating TB treatment and ART in pregnant women is the same as in men and non-pregnant women (please see Table 2 in section III.2.2 above). • Condoms should be recommended to TB/HIV-coinfected pregnant women as well as to all HIV monoinfected women to reduce risk of HIV superinfection (additional infection with the same or another HIV subtype) and other STIs. • Most first-line TB drugs are safe for use in pregnancy. The exception is streptomycin, which is ototoxic to the fetus and should not be used during pregnancy (except for meningeal infections) or lactation due to the potential for serious adverse reactions in nursing infants (43). • If a TB/HIV-coinfected woman decides to carry a pregnancy to term, she should receive ARV prophylaxis for prevention of mother-to-child transmission. For further information please refer to Protocol 10, Prevention of HIV infection transmission from HIV-infected mothers to their in- fants. • If proper case management of TB and ART is carried out, the monitoring of treatment should be the same as for other adults. 3.5. Injecting drug users The clinical management of TB/HIV in IDUs is challenging and requires more effort due to the following factors: • interaction of TB and ARV drugs with illicit drugs and resultant increased hepatotoxicity in those IDUs receiving opioid substitution therapy; • a decrease in methadone levels (33–68%) or withdrawal caused by rifampicin (the methadone dose may need to be increased); • larger likelihood of coinfection with hepatitis C and/or B, and therefore of potential drug interac- tions with hepatitis drugs; • decreased adherence levels; and • decreased access to the health care system. Collaboration with harm-reduction programmes (44, 45) may be essential in organizing effective outreach services such as education, screening, TB preventive treatment, directly observed treat- ment (DOT) for TB and the tracing of treatment defaulters. It is important to keep in mind the following. • Rifampicin should not be administered with LPV/r, NFV or SQV in patients receiving metha- done substitution therapy. Rifabutin is an option, administered as 150 mg 3 times/week with 145 ManageMent of tuberculosis and HiV coinfection LPV/r or 300 mg 3 times/week with NFV. • Rifabutin should not be used together with SQV. For more information, please refer to Protocol 5, HIV/AIDS treatment and care for injecting drug users. 4. Monitoring TB/HIV-coinfected patients 4.1. Monitoring TB treatment For most patients, unless there is drug resistance, TB treatment is effective, and their clinical status improves starting in the second or third week. In TB patients with advanced HIV infection or with late diagnoses for both diseases, a clinical or radiological worsening may be observed. Moreover, treatment with normally effective TB drugs may be unable to reverse clinical course in the late stages of HIV. During the initial 2–4 weeks of TB treatment, during which patients are preferably hospitalized, a complete clinical evaluation should be done at least weekly. ALT must be assessed at least once at the end of the first month. Hepatotoxicity may be observed in up to 5–10% of coinfected patients. A patient’s ability to swallow a pills should be verified, and adherence should be checked regularly. Exceptionally, severe chronic diarrhoea can be responsible for drug malabsorption and treatment failure; such a condition requires the use of injectable TB drugs. Even without diarrhoea, HIV-in- fected patients may not absorb rifampicin adequately. In case of severe gastrointestinal intolerance, which occurs in up to 10% of HIV patients, priority should be given to TB treatment and ART stopped until recovery from gastrointestinal symptoms. TB treatment stops at the end of the continuation phase. There is still not enough evidence support- ing the utility of secondary TB treatment in preventing further relapses. For patients who adhere to TB regimens, the prognosis for TB itself is good. Exceptions are: • patients with MDR-TB, who should be referred to specialized treatment centres because of their complex management; and • patients who are just beginning TB treatment at an advanced HIV/AIDS stage. 4.2. Monitoring antiretroviral treatment Monitoring patients receiving ART should include clinical signs and symptoms, immunological and virological criteria, and ARV toxicity and side-effects. After initiation of ART, immune reconstitu- tion inflammatory syndrome (IRIS) can occur, especially in severely immunosupressed patients. Such worsening of clinical HIV/AIDS disease after initial improvement may occur in up to a third of patients with TB who have started ART. The average time of onset is two months after ART ini- tiation, but it can occur as early as five days after. IRIS is thought to be the result of immune restitu- tion due to administration of antiretroviral and/or TB drugs. IRIS is more common if ART is started early in the course of TB treatment, and if the patient has a very low CD4 count (46, 47). The exacerbated signs and symptoms are due to a more effective local tissue reaction to infection, due to M. tuberculosis or some other opportunistic infection(s). These signs and symptoms include a combination of: • high fever • occurrence or enlargement of peripheral or mediastinal lymphadenopathy • expanding lesions in the central nervous system • worsening of chest radiographic findings. 146 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION The diagnosis of IRIS should be made only after a thorough evaluation has already excluded other etiologies, particularly a failure of the TB treatment. Most cases resolve without any intervention, and ART can be safely continued. Serious reactions, such as tracheal compression due to massive adenopathy or respiratory therapy, may require a short course of steroids. Prednisone may be given at the dose of 20–60 mg/day for at least two or three weeks, gradually decreasing in dose over at least one month (48, 49). For information about ARV drug toxicity and its management please refer to the section Manage- ment of ARV toxicity and side-effects in Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents. Patients treated for TB and HIV should be followed regularly for clinical evaluation of tolerance to treatment. The tests to be performed are summarized in Table 7. Table 7.

Adherence to TB treatment and ARV treatment Adherence is crucial for the success of both TB and ARV treatment. Patients with poor adherence are at very high risk for developing drug-resistant strains of M. tuberculosis and HIV. Drug-resistant TB and HIV are very difficult to treat effectively and can be transmitted to others. DOT is recom- mended to reinforce adherence to TB treatment, combined with context-specific and patient-sensi- tive support (50). For ART, more than 95% adherence is required to achieve optimal HIV suppres- sion and treatment outcome (51). The importance of adhering to treatment and consequences of poor adherence should be fully understood by patients and properly covered during patient counselling. 147 ManageMent of tuberculosis and HiV coinfection Adherence to treatment of TB and HIV/AIDS should be closely monitored and explored at every visit. The effective management of adverse reactions to drugs is very important and considered an essential condition for ensuring adherence to treatment (For more information on adherence please see the sections Adherence to ART and Monitoring adherence both in Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents). For both TB and ART, adherence may be challenging in special population groups, such as IDUs. (For detailed information about factors influencing adherence in IDUs, please refer to Protocol 5, HIV/AIDS treatment and care for injecting drug users.) 148 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION IV. Identification of TB/HIV in infants and children Children are usually infected with TB through contacts with an adult or another child with sputum smear-positive PTB, often a family member. In the absence of interventions to prevent its transmis- sion, infants typically acquire HIV when exposed to HIV-infected fluids (principally blood) in utero or during labour. Without preventive TB treatment, 40–50% of HIV-positive infants and 15% of HIV-positive older children will present with symptoms of TB disease within one or two years of becoming infected with TB. In infants, the time between TB infection and TB disease may be as little as 6–8 weeks. Special considerations should be given to infants born to HIV-positive women who start TB treat- ment less than two months before delivery. These infants should be evaluated for signs and symp- toms of congenital TB and be treated if appropriate. Children older than 7 and adolescents usually develop adult-type pulmonary TB disease with clas- sic presentation. Many children younger than 4, however, show atypical presentations of extrapul- monary dissemination with hepatomegaly, prolonged fever, lymphadenopathy, anaemia and weight loss, clinical manifestations of more advanced phases of immune suppression. 1. Identification of TB in HIV-infected infants and children Diagnosis of TB in infants and children is difficult, whether or not they are infected with HIV, because they rarely have cavitary pulmonary disease and do not produce sputum for bacteriologi- cal examination. Other methods of obtaining material, such as gastric lavage, can be problematic. Consequently, bacteriological confirmation is usually not possible, and the diagnosis of pulmonary TB in children is often presumptive. The diagnosis of TB in HIV-infected children is even more dif- ficult, as several HIV-related diseases may present in a manner similar to TB, and the interpretation of the tuberculin skin test is also less reliable. TB diagnosis is thus often based on a combination of a history of contact with an adult TB infectious case, TB clinical signs and symptoms and the results of the investigations. See Table 8 (15). Table 8. conditions linked to active tb disease in children Suspected tuberculosis • A history of contact with a confirmed case of pulmonary TB • Failure to regain normal health after measles • Weight loss, cough and wheeze that do not respond to antibiotic treatment for respiratory disease • Painless swelling in a group of superficial lymph nodes Probable tuberculosis Suspected TB with any of the following: • positive (≥5 mm) induration on tuberculin skin test • suggestive appearance on chest radiograph • suggestive histological appearance on biopsy material • favourable response to TB-specific therapy. Confirmed tuberculosis • Detection by microscopy or culture of tubercle bacilli from secretions or tissues • Identification of tubercle bacilli as Mycobacterium tuberculosis by culture characteristics 149 ManageMent of tuberculosis and HiV coinfection 2. Identification of HIV in children with active TB HIV infection may be suspected in children with TB. Diagnosis of HIV infection in infants <18 months old should be done using the HIV DNA polymerase chain reaction (PCR) test. In children 18 months and older, the ELISA serological test followed by a confirmatory western blot test is recommended. For further information please refer to Protocol 11, Paediatric HIV/AIDS treatment and care. 150 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION V. Clinical management of TB/HIV in children 1. Treatment of TB TB treatment of HIV-infected children is a priority and should start as soon as active TB disease is diagnosed. The recommended TB treatment regimens for children are the same as those recommended for ado- lescents and adults (see Table 1 in section III.2.2.1. above). The drug dosages per kilogram of body weight are also the same (see Annex 1). 2. Treatment of HIV/AIDS 2.1. Initiation of ART In HIV-infected children with confirmed TB disease, initiating TB treatment should be a priority. ART should be initiated as soon as possible (52), taking into consideration the clinical and immu- nological criteria summarized in Table 9. Table 9. strategy for initiation of art in HiV-infected children with active tb Criteria TB.treatment ART Paediatric.Clinical Stage.4a, b Start immediately Start immediately Start ART soon after TB treat- ment (2–8 weeks after starting TB treatment).

Recommended HAART regiments The ART regimens recommended for TB/HIV-coinfected children differ slightly from recommen- dations for HIV-monoinfected children. The choice of ART regimen is complicated by the lim- ited options for paediatric drug formulations and/or dosing information (particularly for children younger than 3). 2.3. Key considerations for ARV drugs • In case of ZDV toxicity or intolerance, stavudine (d4T) can be substituted. • If NVP is administered concomitantly with rifampicin, potential liver toxicity needs to be moni- tored clinically and with a liver function test. • EFV is not currently recommended for children <3 years of age, nor should it be given to sexual- ly active girls who do not use adequate contraception or are in the first trimester of pregnancy. • Following completion of TB treatment, it is preferable to maintain the ART regimen outlined in Table 10. Table 10.

Cotrimoxazole primary prophylaxis TB/HIV-coinfected children should receive cotrimoxazole prophylaxis during the whole TB treat- ment phase, independent of their level of immune suppression. For cotrimoxazole formulations and dosages, please see Protocol 11, Paediatric HIV/AIDS treatment and care, section on prevention and management of OIs. 3. Monitoring of TB/HIV-coinfected children Routine monitoring of TB/HIV-coinfected children and their response to treatment should include monitoring of clinical signs and symptoms, laboratory indicators, adherence and growth (nutrition). Sputum-smear assessments should be performed the same as for adults: week 8, month 5, month 6, month 8 and month 12 after initiation of TB treatment. For more information on the clinical management of HIV/AIDS in children, please refer to Protocol 11, Paediatric HIV/AIDS treatment and care. 152 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION VI. Suggested minimum data to be collected at the clinical level It is recommended (52) that the following data be collected on a regular basis (e.g. monthly, quar- terly or semi-annually) at the clinical level to improve clinical management of TB/HIV-coinfected patients and to monitor the implementation of collaborative TB/HIV activities: • number of registered TB patients; • number of registered TB patients who are tested for HIV; • number of registered TB patients testing positive for HIV; • number of HIV patients seen for treatment and care who are screened for TB symptoms; • number of HIV patients who have TB infection: ° number of HIV patients with TB infection who have received tuberculosis preventative treat- ment (TPT) with izoniazid; • number of HIV patients who are newly diagnosed with TB disease: ° number of HIV patients newly diagnosed and registered with TB disease who have CD4 ≥350 cells/mm3; ° number of HIV patients newly diagnosed and registered with TB disease who have CD4 <350 cells/mm3; ° number of HIV patients newly diagnosed with TB disease who have received cotrimoxazole preventive therapy2 (CPT); • number of HIV/TB patients who are receiving TB treatment; • number of HIV/TB patients receiving both TB treatment and ART;3 • number of HIV/TB patients in each category of TB treatment outcome;4 • number of HIV/TB patients who have died, including cause of death (e.g. TB-related deaths, other HIV/AIDS related mortality or non-HIV/AIDS related mortality such as accident, over- dose or suicide). 2 Defined as at least one dose during their TB treatment. 3 Including the number of patients who have started on ART or are continuing previously initiated ART during or at the end of TB treatment 4 This indicator should be calculated for each of the following possible outcomes: cure, treatment completion, treatment fail- ure, death, default and transfer out. For definitions of these outcomes please refer to Treatment of tuberculosis: guidelines for national programmes (53). 153 ManageMent of tuberculosis and HiV coinfection Annex 1.

I. Policy and principles Substance dependence is a complex condition, with profound consequences for the health of drug users, for public health and for health care systems, particularly when the substances are injected. The World Health Organization (WHO) and others have committed to scaling up access to high- ly active antiretroviral treatment (HAART and have confirmed that injecting drug users IDUs) should have equitable and universal access to HIV/AIDS prevention, treatment and care, including HAART (1). While this protocol has been produced specifically for countries in the WHO European Region, it should be equally useful for countries in other regions where injecting drug users require HIV/AIDS treatment and care. Although the overwhelming majority of HIV cases in eastern Europe are IDUs, they are the least likely to receive HAART (2–4). Drug users have suboptimal access to and utilization of HAART and initiate it at more advanced stages of infection (5). Patients with a history of injecting drug use have lower rates of access to HAART, even in developed countries with relatively good access for the general population (6–9). Many studies show that clinicians are reluctant to prescribe antiret- rovirals (ARVs) to HIV-infected IDUs, due to the common belief that they may have lower levels of adherence that may in turn lead to elevated rates of ARV resistance, whereas studies show that resistance levels are similar among IDUs and non-IDUs (10). Where comprehensive HIV care has been provided to IDUs in an accessible and non-judgemental way, large proportions of them have been attracted to, and retained in, effective treatment. Combining HIV/AIDS care with substance dependence treatment services (including harm reduction, detoxification and substitution therapy) and psychosocial services has been particularly successful (1, 4, 11–13). WHO has a long tradition of working in HIV/AIDS prevention, treatment and care for IDUs and prisoners, guided by a broad range of WHO and United Nations resolutions, commitments, policies, position papers and technical documents. The work is now solidly evidence-based on the concept of harm reduction. The 1974 report of the WHO Expert Committee on Drug Dependence statement that programmes should be more concerned about preventing and reducing problems related to drug use rather than preventing drug use itself, predates HIV/AIDS and provides the rationale for WHO’s public health approach to addressing drug-related problems within a harm-reduction framework (14). The term “harm reduction” is sometimes used to refer to all drug-related harm, but in the context of HIV/AIDS, WHO also uses the term to describe a comprehensive package of evidence-based inter- ventions that reduce HIV transmission and the HIV/AIDS impact associated with drug use, particu- larly drug injecting. However, a harm-reduction approach is also effective against other bloodborne infections (notably hepatitis C), overdosing and other individual and public harms. A comprehen- sive strategy for the prevention of drug-use-related HIV epidemics must include programmes aimed at the primary prevention of drug use. Yet the comparative advantage of the WHO approach rests with interventions delivered through the health sector,1 particularly those targeting current users and, increasingly, prisoners. WHO recognizes that HIV/AIDS prevention, treatment and care for drug users and prisoners requires a comprehensive approach with a range of interventions. 164 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION In May 2003 the 56th World Health Assembly endorsed the WHO Global Health Sector Strategy (GHSS) for HIV/AIDS 2003–2007, which lists the core components of a comprehensive health sec- tor response to HIV/AIDS, including “promoting harm reduction among injecting drug users, such as wide access to sterile injecting equipment, and drug dependence treatment and outreach services to help reduce frequency of injecting drug use” (15). WHO has recently renewed its commitment to providing universal access to HIV/AIDS prevention, care and treatment for all who need it, in which harm reduction is a priority intervention guided by a number of technical papers and policy briefs (1, 14–23). The WHO Regional Office for Europe has been at the forefront of harm-reduction efforts. In 1998, the Regional Office, in cooperation with UNAIDS and the Council of Europe, published its basic principles for effective prevention of HIV infection among IDUs. It was among the first United Nations publications to set out basic principles for effective prevention among IDUs, explicitly mentioning provision of sterile injecting equipment and opioid substitution therapy (OST). The current mandate for the Regional Office work on harm reduction in Europe is provided in the 2002 resolution of the WHO Regional Committee for Europe (EUR/RC52/R9), Scaling up the response to HIV/AIDS in the European Region of WHO, which urges Member States: … to promote, enable and strengthen widespread introduction and expansion of evidence-based targeted interventions for vulnerable/high-risk groups, such as prevention, treatment and harm reduction programmes (e.g. expanded needle and syringe programmes, bleach and condom dis- tribution, voluntary HIV counselling and testing, substitution drug therapy, [sexually transmitted infection] STI diagnosis and treatment) in all affected communities, including prisons, in line with national policies. In February 2004, the Regional Office also helped draft the landmark Dublin Declaration on Part- nership to Fight HIV/AIDS in Europe and Central Asia, in which all European Region Member States committed to: Scale up access for injecting drug users to prevention, drug dependence treatment and harm re- duction services through promoting, enabling and strengthening the widespread introduction of prevention, drug dependence treatment and harm reduction programmes2 (e.g. needle and syringe programmes, bleach and condom distribution, voluntary HIV counselling and testing, substitution drug therapy, STI diagnosis and treatment) in line with national policies… (17). The following principles should be applied to IDUs living with HIV. • HAART is as effective for HIV-positive IDUs as it is for other people with HIV/AIDS. • Given appropriate support, former and active IDUs can adhere just as well as others and should have equal access to HAART. • Current or past drug use should not be a criterion for deciding who should receive antiretroviral treatment (ART). • Special attention should be paid to the particular needs of former and active IDUs when admin- istering HAART, including those related to substance dependence, comorbidities and coinfec- tions. • A public health policy that addresses the need to treat both substance dependence and HIV/ AIDS improves patient well-being, reduces stigmatization and promotes delivery of compre- hensive, ethical medical care. 2 WHO recommends that at least 60% of IDUs have access to drug dependence treatment and harm-reduction programmes in order to have an impact on the epidemic among this group. 165 HIV/AIDS TREATMENT AND CARE FOR INJECTING DRUG USERS • The most effective response consists of a combination of prevention, treatment, care and sup- port within a harm-reduction framework. • Harm reduction is highly effective for IDUs in supporting prevention, treatment and care. • Provision of good quality OST is an essential component of HIV/AIDS treatment and is highly effective in addressing opioid dependence. • A supportive environment that upholds the human rights and dignity of IDUs and helps expand and improve access to drug dependence treatment should be ensured. • Countries with HIV epidemics fuelled by injecting drug use should respond immediately to the needs of IDUs with preventive and treatment services, including harm reduction, opioid substi- tution therapy and equitable access to HAART. 166 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION II. Background and general considerations 1. HIV and injecting drug use epidemiology Estimates suggest that by the end of 2003 there were approximately 13.2 million IDUs worldwide, the majority, 10.3 million (78%), in developing and transitional countries. The number of IDUs in western Europe has been estimated at 1.2 million, with 3.2 million in eastern Europe and central Asia (24). HIV epidemics in many parts of the world are driven by injecting drug use and sexual contact with IDUs. Estimates indicate that at least 10% of all new HIV infections in the world – 30% if Africa is excluded – can be attributed to injecting drug use, and that approximately 3 mil- lion past and current IDUs are living with HIV (25, 26). In eastern Europe, HIV epidemics have been driven almost entirely by injecting drug use. Estonia, the Russian Federation and Ukraine have the largest and most widespread epidemics (27, 28). HIV prevalence rates among IDUs differ widely in western Europe, with the highest rates in Spain, Italy and Portugal (24). The countries most affected are those where access to prevention, treatment and care is limited, where needle and syringe programmes and drug substitution therapy are not widely available or illegal, and where law enforcement is the dominant approach to drug use (29, 30). Explosive growth is characteristic of drug-driven HIV epidemics. In some cases, HIV prevalence among IDUs has risen from around 1% to as much as 70% in a few years (31, 32). Rapid increases of injecting drug use also often coincide with the most rapid increases in HIV/AIDS. Drug use- driven HIV epidemics typically start with IDUs who are young, male and sexually active, and are then followed by sexual transmission to male and female partners as well as to children through mother-to-child transmission (MTCT). Commercial sex work can act as a bridge between popula- tions through the exchange of sex for drugs or through sex work to support drug use (33). These explosive epidemics can be explained by the lack of access to prevention and treatment (notably harm reduction), together with the efficacy of bloodborne transmission through sharing needles, syringes and other drug paraphernalia. An additional factor is the elevated level of virae- mia characteristic of the first weeks and months after seroconversion, which may contribute to the high HIV-transmission rates typical of these epidemics (4). Social and environmental factors also contribute to IDU/HIV epidemics (34). 2. Health and social consequences of injecting drug use Substance dependence is a complex condition that has both physical and psychosocial components and is associated with severe morbidity and a high risk of death. Substance dependence (particularly opioid dependence) is a chronic relapsing condition, which is difficult to control due to compulsive drug use and craving, leading to repetitive use, even in the face of negative health and social conse- quences (35). There are a number of medical, psychiatric and social problems common among sub- stance-dependent people that are important considerations in designing and delivering HIV/AIDS care. 2.1. Health problems In addition to HIV, IDUs usully have a wide range of coinfections, coinfections, comorbidities and injecting related health issues. The most common health problems among IDUs are: • infection with bloodborne viruses, including hepatitis B, C and D (delta) leading to liver dis- eases • bacterial infections: (36) ° tuberculosis 167 HIV/AIDS TREATMENT AND CARE FOR INJECTING DRUG USERS ° bacterial pneumonia ° endocarditis ° septicaemia • overdoses • alcohol dependence and alcohol-related liver disease • polysubstance dependence • psychiatric comorbidity, including depression. Some IDUs have a long history of mental illness without proper diagnosis or treatment. There are some mental conditions that may result from, or be exacerbated by, the use of substances such as alcohol, cocaine and opioids. These substances may also be used by individuals as a form of self-medication for symptoms of mental illness and substitute for effective treatment. A substantial increase in the frequency of major depression and suicide in HIV-positive IDUs is apparent, even above the elevated rates associated with advanced HIV infection and AIDS (37–39). Other frequent injecting related prolems include: • deep venous thrombosis (DVT) or pulmonary embolism (PE) • local soft tissue and vascular injuries, including skin abscesses and thrombophlebitis • increased risk of respiratory and smoking-related illnesses and chronic diseases. 2.2. Social problems Common perceptions that drug users do not adhere to HAART may overlook the confounding effects of social instability, poverty, psychiatric morbidity, human rights violations and poor pa- tient–physician relationships that characterize many drug users’ lives. IDUs’ most prevalent social problems include: • stigmatization, discrimination and social marginalization • poverty • homelessness • unemployment • family and social dysfunction • criminal behaviour and imprisonment. 2.2.1. Stigmatization, discrimination and social marginalization Drug use is a prevailing source of stigmatization and discrimination beyond that associated with positive HIV status. • The stigma attached to drug use is often reinforced because it is typically an illegal and covert activity, with no legal protection available to people who use drugs. • Drug users are often reluctant to attend medical facilities because of stigmatization and discrim- ination. Fear of discrimination may discourage HIV-infected drug users from revealing their drug use to HIV/AIDS care specialists, leading to a greater risk of misdiagnosis, or of pharma- cological interactions between the HIV treatment regimens and the substances used (4). • Many IDUs live on the economic and social fringes, and may be rejected by their families. • People who are most vulnerable to the impact of poverty, racial discrimination, poor health, lack of education and employment are also those most vulnerable to drug use. • Social problems, including the stigma and discrimination associated with drug use and being HIV-positive, in turn exacerbate drug use. 2.2.2. Prison The economic pressure of supporting drug dependence and the crime that results mean that in most countries, a large proportion of drug users are periodically incarcerated. Many countries have some form of compulsory detoxification or abstinence-based treatment in closed settings as the predomi- nant type of treatment for drug use. There is no evidence that such approaches are effective as forms 168 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION of drug dependence treatment; furthermore, they bring a range of problems with them. Health prob- lems associated with incarceration include: • unsafe drug use with the risk of disease infection and transmission for other communicable dis- eases, including hepatitis; • tuberculosis (TB) (particularly multidrug-resistant TB); • unprotected sex between prisoners, with risk of transmitting HIV and other STIs; • increased risk of overdose after release; • physical and sexual assault; • depression and anxiety; and • suicide. Explosive HIV epidemics within prisons have been reported in a number of countries, and can trig- ger or significantly affect broader HIV epidemics. 3. Opioid substitution therapy practice The global number of opioid dependants receiving prescribed methadone is estimated to be over half a million – including nearly 400 000 in the European Region (19, 40) – and it is increasing in practically all regions. Originally implemented in Australia, the United States and western Europe, methadone maintenance treatment is expanding eastwards to central and eastern Europe, to the eastern Mediterranean region and Asia. Methadone covers up to 80% of estimated treatment needs in some European countries, in others much less. In the European Region, 76% of substitution treatment programmes use methadone (41). In the United States, 179 329 patients were enrolled in methadone maintenance treatment programmes at the end of 1998; more recent estimates range from 200 000 to 300 000. Methadone is also being used in Argentina, Australia, Canada, China, In- donesia, the Islamic Republic of Iran, New Zealand and Thailand, among other countries. It is esti- mated that a million opioid dependants will be in methadone treatment within the next five years. The global number of opioid dependants receiving prescribed buprenorphine is estimated to be close to 200 000 and increasing in practically all regions. The greatest level of experience with buprenorphine has been in France, where it has been widely available through general practitioners since 1995. In 1998, approximately 65 000 patients there per year were in buprenorphine treatment. By 2001, 74 000 were in buprenorphine treatment while 9600 were treated with methadone (42). In Australia, buprenorphine was registered for the treatment of opioid dependence in 2001, and there were 8641 patients receiving it by June 2003. In 2005 it was available in countries including Aus- tralia, Austria, Belgium, China (Hong Kong Special Administrative Region), the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Iceland, India, Indonesia, Israel, Italy, Lithu- ania, Luxembourg, Malaysia, the Netherlands, Norway, Portugal, Singapore, Slovakia, Slovenia, South Africa, Sweden, Switzerland, Ukraine, the United Kingdom and the United States. 169 HIV/AIDS TREATMENT AND CARE FOR INJECTING DRUG USERS III. Organization and management considerations 1. Services The organization of HIV prevention, treatment and care services and their linkage are important de- terminants of successful treatment of IDUs. HIV treatment programmes should be linked to harm- reduction services to facilitate enrolment and retention of IDUs, and to ensure that those in treat- ment can readily access risk reduction advice, counselling and relevant commodities (clean needles and syringes, condoms, etc). Harm-reduction strategies, including drug substitution therapy, can limit medical and psychosocial complications of drug use and can facilitate HIV care by stabilizing IDU behaviour. Four types of linked services are crucial in the treatment of substance dependence and HIV/AIDS: • general medical care and/or clinical infectious disease care • harm reduction • drug dependence treatment • psychosocial support. Outreach strategies can form strong links with community-based organizations representing af- fected groups, and utilize peer educators and counsellors drawn from these groups. 1.1. General medical care services 1.1.1. Principles Successful programmes delivering medical care, including HAART, to active IDUs have identified important principles of medical care: • accessibility • free-of-charge • user-friendly with non-judgmental and unbiased staff • tailoring to individual needs • continuity of care through referral systems among health services, community organizations, injecting drug use networks and families. 1.1.2. Multidisciplinary approach WHO favours a multidisciplinary approach for the provision of treatment and care for people living with HIV (PLHIV). The care team should have experience with drug-dependency issues and should meet on a regular basis to review the status of IDUs under treatment and provide case management. The formation of a care team typically includes: • a clinician (a physician, infection disease specialist or other medical practitioner) • a medical nurse • a social worker • a counsellor • a substance dependence specialist.3 Psychiatrists and psychiatric services are not necessarily the most appropriate to provide substance dependence treatment. Many of the complications that need treatment are those best managed by physicians. There is the risk of additional stigmatization of drug users because of their association with psychiatric services, particularly if they do not have psychiatric comorbidity. 3 This may be an addiction specialist, a psychiatrist or psychologist and/or (in eastern Europe) a narcologist. 170 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 1.1.3. Components A major challenge in delivering care to IDUs is their need for concurrent services addressing both biomedical and psychosocial issues. Medical care should be comprehensive and should provide: • HIV/AIDS treatment • substance dependence treatment, inclcuding opioid substitution therapy • diagnosis and treatment of other comorbidities and injecting related health issues (see section II.2.1) • prophylaxis/suppression for specific HIV opportunistic infections4 • vaccination for hepatitis B virus (HBV)5 • palliative care for patients with advanced disease.6 While providing medical care to IDUs it is essential in medical settings to also address: • treatment adherence; • reduction of drug use and sexual risk behaviours; • information on injecting techniques to decrease the complications of injection; • support for sexual partners; • support social matters (through social services); • reducing and avoiding stigmatization and discrimination through: ° ensuring the human rights of IDUs are respected, and that they receive quality services ad- dressing their health needs, including HAART; ° ensuring that health care workers are aware of their own feelings and prejudices and of the effect these may have on their patients, their professional performance and the successful outcome of drug-dependence treatment and HAART; ° guarantee confidentiality. The ready availability of such services will enhance a programme’s credibility, while their absence will signal a lack of concern for the immediate needs of IDUs (43). 1.2. Harm reduction Harm-reduction interventions reduce the adverse health, social and economic consequences of psy- choactive substance use for individual drug users, their families and their communities, without necessarily reducing or eliminating drug use. Appropriate support, provided by accessible and non- judgemental health care teams and delivered through community-based programmes and outreach strategies, has proven highly effective. Comprehensive harm-reduction programmes reduce new HIV infections among IDUs (16, 44–46). The key components of an effective harm reduction package targeting drug users include: • community outreach, with a focus on peer approaches; • behavioural change communication, including risk-reduction information; • needle and syringe access and disposal; • drug dependence treatment, particularly OST; • HIV testing and counselling; • condoms and STI prevention and treatment; • primary health care, including hepatitis B vaccination, vein and abscess/ulcer care, overdose management; and • a supportive policy and legislative environment. 4 For example, Pneumocystis jirovecii pneumonia (PCP), candidiasis, cryptococcosis, toxoplasmosis, Mycobacterium avium complex and cytomegalovirus. Interactions between antifugals commonly used in the treatment of candidiasis and cryptococ- cosis and methadone should be considered. 5 Please refer to Protocol 8, Prevention of hepatitis A, B and C and other hepatotoxic factors in people living with HIV, and Protocol 12, Immunization of people living with HIV and people at risk for HIV infection. 6 Please refer to Protocol 3, Palliative care for people living with HIV. 171 HIV/AIDS TREATMENT AND CARE FOR INJECTING DRUG USERS Harm-reduction services should be involved in: • HIV/AIDS treatment delivery where feasible, including the provision of direct ART services; • ART adherence support, including maintaining follow-up of IDUs who drop out of care; • providing low-threshold (easy to access) entry points for both HIV/AIDS and drug-dependence treatment; • providing information on: ° safer drug use and HIV prevention ° potential interactions between psychoactive drug use and HIV/AIDS treatment ° ARV treatment, including how to manage side-effects; • referrals to other harm-reduction services, including drug-dependence treatment programmes, community support services and other health care services; • planning HIV treatment for IDUs; and • conducting outreach to IDUs for HIV testing, counselling, treatment and care. 1.3. Drug-dependence treatment and OST Management of drug-dependent individuals should also involve a multidisciplinary team, including physicians, nurses, counsellors, outreach workers, social workers and pharmacists (47). Govern- ment agencies, nongovernmental organizations (NGOs) and community groups should assist in the delivery of services. Treatment of drug dependence, including drug substitution therapy, provides many benefits in the prevention and treatment of HIV/AIDS, by: • improving access to HIV treatment and care and general health care • retaining active drug users in treatment • reducing the transmission of HIV, viral hepatitis and bacterial infections • decreasing the need for hospitalization • improving and facilitating adherence to and follow-up of HAART (1, 3, 11, 45, 48–51). It also assists in: • reducing illicit opioid use • reducing criminal activity • decreasing deaths due to overdose • cutting down on high risk behaviours for HIV transmission • improving social integration. The benefits of substitution therapy programmes can be maximized by: • prescribing higher rather than lower doses of methadone or buprenorphine; • orienting programmes towards maintenance rather than abstinence; • offering assessment and treatment of psychiatric comorbidity and social problems; • using contracts between patient and clinician or contingency management and counselling to reduce the use of additional drugs; • ensuring ready access to services, e.g. by making location, opening hours and cost convenient; and • providing a user-friendly environment (52–54). Where substitution therapy is available, consideration should be given to offering HIV/AIDS medi- cal care and providing HAART at the same site from which drug substitution therapy is provided. This approach can: • achieve maximal levels of treatment supervision • enhance efficacy • reduce the risk of developing ARV drug resistance • facilitate the management of interactions between methadone and HIV/AIDS medications. 172 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Other benefits of prescribing HAART in OST clinics include: • the possibility of concurrent long-term treatment for drug dependence and HIV/AIDS; • the opportunity to use directly observed treatment (DOT) in dispensing ART to patients who already visit the clinics daily to receive methadone;7 and • experience in treating medical conditions related to substance use (1, 51). There is evidence that DOT is an effective strategy in the provision of HAART with treatment for substance dependence. Using DOT to provide HAART in conjunction with methadone maintenance is recommended because it: • results in significant numbers of patients achieving maximum viral suppression (11); • achieves higher levels of viral suppression than either standard care or treatment adherence sup- port (48); and • minimizes the impact of HAART on the IDU’s daily routine. 1.4. Psychosocial support Services that can address both the biomedical needs and the psychosocial issues of IDUs concur- rently are essential. There is a wide range of psychosocial support services that should be available in accordance with the patient needs of IDUs, including: • support services for adherence to ART; • psychological support, such as group therapy for IDUs and family members; • peer support groups; • educational programmes; • psychiatric/psychological services for assessment and management of mental health disorders; and • social services to deal with problems related to housing, employment, finances, legal matters, discrimination and other issues. Former IDUs often have been uniquely successful in educating and motivating current IDUs to: • access effective prevention, treatment and care services • prepare for treatment, e.g. through advice on possible side-effects associated with ARVs • adhere to HAART and other treatments. 2. Models of comprehensive HIV/AIDS care for IDUs HIV/AIDS treatment and care, including HAART, should be delivered as part of a comprehensive care model. Combining or integrating HIV/AIDS and substance dependence services provides op- portunities for HIV prevention, enhances adherence to both HIV/AIDS and substance dependence treatment and provides better overall care. A comprehensive service develops expertise in effective- ly treating substance dependence and providing HIV care. There are several models for effectively combining HIV prevention, treatment and care with substance dependence treatment, including: • a single site for both HIV/AIDS care and substance dependence treatment: ° on-site HIV/AIDS medical care in substance dependence treatment facilities or ° substance dependence treatment in HIV/AIDS services;8 • separate HIV/AIDS and substance dependence treatment services in close proximity with good coordination and liaising, including referrals to other services; and • primary care services for both drug dependence management and HIV/AIDS care through gen- eral practitioners or office-based practice. 7 A second “take-home” dose of ARV drugs is also likely needed. 8 A variation on the one-site model is a mobile health care service linked, for example, to a HIV/AIDS medical care centre, a substance dependence treatment facility or a harm-reduction service. Mobile services can provide HIV and STI screening, HIV/AIDS treatment, referrals for substance dependence treatment and mental health and other services. 173 HIV/AIDS TREATMENT AND CARE FOR INJECTING DRUG USERS The effectiveness of the models will depend on the infrastructure and organization of the health care system. Where specialized departments (for example, drug treatment centres and departments of internal medicine) exist, liaising and case management should be common practice. 3. Prisons Reaching IDUs in prisons and other closed settings is crucial because prisons exacerbate the risks of both HIV infection and drug dependence. Incarcerated IDUs should receive the same package of services as those who are not incarcerated, including HAART. Treatment for HIV/AIDS and/or substance dependence may have begun prior to imprisonment, and HAART should continue in prison (55). Providing prevention, treatment and harm-reduction interventions to IDUs in prison benefits in- dividual inmates as well as the community at large (22, 56, 57). Comprehensive programmes in prisons should include: • information, education and communications on HIV/AIDS • voluntary testing and counselling • condoms • bleach or other disinfectants • needle and syringe exchange • substitution therapy • clinical management of drug-dependent prisoners that meets local community standards • HIV/AIDS services (including ART), as well as hepatitis and TB services • follow-up care with links to community services • treatment of other substance dependency problems. Upon release, prisoners need to be guaranteed continuity of care (58). There is a need to forge strong links between communities and drug dependence treatment centres, prisons, labour camps and other centres of detention, as many drug-dependent people move back and forth between the community and such closed settings. Closed settings should be seen as opportunities for HIV pre- vention, treatment and care and should be monitored and evaluated for a range of indicators that cover drug use, HIV and social issues. Guidance on HIV prevention and treatment in prisons and other closed settings is available from WHO (59, 60). 174 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION IV. Clinical management of HIV-infected IDUs 1. Initial evaluation Care for HIV-positive IDUs must address substance use and substance dependence, psychological and social issues, and medical complications associated with injecting drug use and HIV/AIDS. 1.1. Evaluation of substance use and dependence Standardized assessment tools should be used for screening and initially evaluating substance use and dependence. Preferred screening and assessment instruments are suggested below and in the annexes. In Europe, the preferred assessment instrument is the European version of the Addiction Severity Index (EuropASI; see Annex 1). Any screening or assessment must be voluntary and fully informed, with explanation of why the service needs to understand the individual’s substance use and associated problems. Under-reporting use of illicit substances is common, so all patients should be screened for substance use and dependence (see Annex 2 for alcohol and drug listing). Patients who admit to substance use should be examined further, as should those who do not but present the clinical signs or symptoms of drug use, including injections. It is crucial to assess drug dependency, as it has implications for patient management strategy. A simple and rapid initial assess- ment of drug dependence can be provided by non-specialized staff, based on 10 questions adapted from the “Symptom checklist for mental disorders” in the International statistical classification of diseases and related health problems, 10th revision (Annex 3). Typically a substance use and dependence assessment includes a complete history of substance use and treatment and a physical examination. A substance use and treatment history will include: • substances used, including alcohol and combinations of drugs, and age at first use • modes of drug administration • lifetime, recent and current use • changes in drug effects over time • history of tolerance, overdose and withdrawal • periods of abstinence and attempts to quit • complications of substance use (hepatitis, abscesses, etc.) • current problems, including severity of dependence • types and outcomes of previous treatment for drug dependence. A physical examination may indicate substance dependence and/or complications associated with substance use. A checklist of physical symptoms such as the examination findings suggestive of ad- diction or its complications (see Annex 4) is useful. The physical complications of opioid or other drug dependence should be identified and addressed as part of the overall treatment plan. Further evaluation of drug dependence severity and appropriate treatment strategy should be done by, or in close collaboration with, substance dependency treatment experts or other trained staff. In addition, risk-taking behaviour associated with bloodborne diseases can be documented using a standardized instrument such as the Bloodborne Virus Transmission Risk Assessment Question- naire (see Annex 5). 1.2. Initial evaluation of HIV/AIDS status Initial evaluation of IDUs’ HIV/AIDS status is no different from that of non-users. Offering HIV testing, counselling and information should be routine procedure in health care settings dealing with IDUs. Health care providers should explain the reasons for offering the test and its importance for correct clinical management. However, a patient has the right to refuse the test. Initial assessment of HIV status should include the following: 175 HIV/AIDS TREATMENT AND CARE FOR INJECTING DRUG USERS • pretest HIV counselling and information; • a serological test for HIV antibodies (typically ELISA and/or rapid tests), followed by a western blot confirmatory test; and • post-test counselling, including information on reducing risk behaviours, whether the results are positive or negative. 1.3. Further clinical evaluation Further evaluation is required for developing a strategy of clinical management of HIV-infected IDUs, including: • presenting symptoms • physical examination9 • mental health and social assessment10 • preparedness for treatment • routine laboratory assessments • CD4 lymphocyte count to determine the severity of immunodeficiency • viral load testing, if available • history of contraception use and pregnancy test if indicated • assessment for hepatitis B and C11 • screening for TB12 • testing for STIs • assessment for psychiatric disorders • weight • other tests based on the patient’s condition. For more detailed information refer to the Protocol 1, Patient evaluation and antiretroviral treat- ment for adults and adolescents. Since many IDUs present for care at an advanced stage of HIV infection, it is important to thor- oughly evaluate new patients for active opportunistic infections. The initial history and physical examination will usually identify common complications, including: • oral candidiasis and difficulty swallowing, suggesting oesophageal candidiasis • non-healing genital or anal ulcers, indicating herpes simplex • fever with cough and/or shortness of breath, suggesting bacterial pneumonia, TB or PCP. These conditions should not be interpreted as exclusion criteria for HAART, but as cases requiring clinical judgement. Initial evaluation should be followed by treatment of opportunistic infections and other conditions as indicated. For further details, please refer to Protocol 2, Management of op- portunistic infections and general symptoms of HIV/AIDS. 1.4. Psychosocial assessment Mental health comorbidities are common among IDUs with HIV. Some estimates suggest that be- tween 25% and 50% of drug users also have a comorbid mental health problem. A thorough psychosocial assessment should be undertaken at initial evaluation, focusing on: • any source of instability that might undermine adherence to treatment • depression and other mood disorders13 • other psychiatric problems. 9 Particular attention should be given to possible indications of substance dependence and its complications (see the previous section, IV.1.2). 10 See the next section, IV.1.4. 11 For more details see Protocol 6, Management of hepatitis C and HIV coinfection, and Protocol 8, Management of hepatitis B and HIV coinfection. 12 For more details see Protocol 4, on Management of tuberculosis and HIV coinfection. 13 Adherence to HAART has been found to be higher for depressed patients who adhere to antidepressant treatment than for those who do not adhere to it or are not given it (61). 176 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION The use of a standardized screening instrument, such as the Brief Psychiatric Rating Scale (BPRS) (62) for psychotic illnesses or the Montgomery Asberg Depression Rating Scale (MADRS) (63), may be of benefit and improve detection of psychological illness. The latter scale may be particu- larly useful for physically ill individuals. Referral for a full mental health evaluation and/or formal psychiatric diagnosis might be indicated. The severity of HIV-related medical problems must be considered throughout psychosocial assess- ment. Social factors to be assessed include: • social stability, family and community support • homelessness • major life events and crises • financial security • nutrition. 2. Management of opioid dependence The management of substance dependence is critical in the care of HIV-positive IDUs as HIV infec- tion and drug dependence in the same person are not isolated problems; each influences the progres- sion of the other. There are a variety of treatment modalities for drug dependence, ranging from drug-free residential to pharmacologically assisted outpatient treatment, including maintenance and detoxification regimens. Given the often chronic nature of substance dependence, detoxification alone is seldom effective in producing long-term and sustained change. Most treatment options focus on opioid dependence and much less on on other kinds of substance dependence. Although in Europe, HIV/AIDS most commonly occurs among people who inject opioids, effective treatment for dependence on cocaine and amphetamine-type stimulants (ATS) should also be provided. A range of interventions for IDUs has evolved from total abstinence to the provision of safe inject- able heroin (64). Staff in substance-dependence services have to have regular ongoing contact with IDUs, whether or not they are on OST. One of the most significant predictors of outcome in the management of drug dependence is reten- tion in treatment. OST programmes retain patients in treatment, making it an ideal modality for the delivery of HAART to HIV-positive IDUs. All drug services should strive toward establishing methadone or buprenorphine maintenance in order to improve treatment outcomes. IDUs are three times as likely not to receive HAART if they are not enrolled in such a programme (65). 2.1. Opioid substitution therapies There are two main modalities for treatment of opioid dependence: pharmacotherapy and psycho- logical therapy. Pharmacotherapies include: • agonist maintenance with oral methadone and levo-alpha-acetyl-methadol (LAAM); • partial-agonist maintenance with sublingual buprenorphine or combination sublingual buprenor- phine and naloxone; • antagonist maintenance with oral naltrexone; and • anti-withdrawal/detoxification agents (methadone, buprenorphine and/or clonidine) for brief periods to facilitate entry into drug-free or antagonist treatment approaches. The two main opioid substitution therapies available in Europe are methadone and buprenorphine. Both high-dose methadone (>60 mg) and buprenorphine substantially reduce the level of illicit opi- oid use in comparison with low-dose methadone (66). It is important to keep in mind that: • Stabilization of opioid-dependent IDUs through OST is a key component to successful HIV/ AIDS treatment, including HAART. 177 HIV/AIDS TREATMENT AND CARE FOR INJECTING DRUG USERS • OST is not universally available, and many HIV-positive IDUs presenting for treatment with ART may still be actively using heroin and other drugs. • Lack of access to OST should not preclude drug users from having HAART. • Active drug use should not preclude HAART. 2.1.1. Methadone Methadone is one of the most effective and most frequently used types of pharmacological OST. Clinical trials have demonstrated the effectiveness of methadone maintenance for the treatment of opioid dependence and prevention of HIV. Such evidence is summarized in key WHO documents (19, 67). Dosages of methadone in different programmes range from 20 to 120 mg per day and sometimes higher. Doses above 60–80 mg per day are better at achieving retention in treatment and reducing illicit drug use. As methadone is metabolized by the cytochrome P450 enzyme system, other medications that inter- act with this enzyme system should be used with caution (see also section IV.4.4.). Patients on methadone treatment may increase alchohol use in place of illicit opioids. IDUs are at an increased risk of liver toxicity and impairment of the metabolism of certain ARV drugs. 2.1.2. Buprenorphine The benefits of buprenorphine maintenance are similar to methadone maintenance and therefore for HIV-infected IDUs on buprenorphine the success of HAART will be increased. In France, where buprenorphine is widely used, studies have reported that for patients on HAART and buprenor- phine, the CD4 count rises and the viral load decreases as expected (68). More recently buprenorphine, a partial opioid agonist, has been used for both detoxification and maintenance. A number of clinical trials have demonstrated the effectiveness of buprenorphine maintenance for the treatment of opioid dependence. Again, key WHO documents summarize the evidence (19, 69). The dosage used in maintenance can range between 12 mg and 34 mg, with an average dose of ap- proximately 16 mg. Due to its pharmacological functioning and partially antagonistic effect, buprenorphine may be safer in overdose than methadone; in addition, it appears to offer a slightly smoother withdrawal during detoxification. It is a sublingual preparation, so care must be taken during dispensing, as there have been reports of crushing and injecting the tablets (70), which could lead to sharing of injecting equipment (71). 2.2. Detoxification programmes (medically supervised withdrawal) Detoxification from opioids is an initial component of some treatment programmes but should never in itself be considered a treatment for opioid dependence. It provides supervision to reduce the severity of symptoms and the medical complications of withdrawal, and it should be tailored to the patient. There are several important points to consider about detoxification. • Detoxification programmes can provide entry points for HAART delivery. • Reduction in methadone and buprenorphine doses should be negotiated with the drug user de- pending on the emergence of withdrawal symptoms. • Access to psychological support should be available throughout the treatment. • Detoxification for opioid dependants can be carried out using tapering doses of different medi- cations including: 178 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION ° methadone (stabilize on 40–60 mg once daily (OD) and reduce by 5 mg per week over 8–10 weeks); ° buprenorphine (stabilize on 8–10 mg OD and reduce over 5-6 weeks); ° clonidine;14 and ° lofexidine (stabilize on 1.2–2.0 mg in divided doses (e.g. four times daily (QID)) and reduce over 2 to 3 weeks). When used appropriately, the medications above can produce safe and less uncomfortable with- drawal, but the majority of patients will relapse into opioid use after withdrawal, regardless of the method or substance used. Relapse rates following detoxification can be reduced by offering after-care support with antagonist therapy, such as naltrexone at 50 mg per day, or 100 mg on day 1, 100 mg on day 3 and 150 mg on day 5. Given that one of the principal problems of naltrexone is compliance (72), some services supervise ingestion in the after-care period. 2.3. Other treatment options In addition to OST, treatment and management options include: • self-help groups • therapeutic communities15 • residential rehabilitation16 • psychological interventions such as: ° cognitive behavioural therapy (CBT)17 ° motivational interviewing18 ° contingency management19 ° matrix model20 ° relapse prevention strategies, medical or psychological • peer support programmes • social skills training • vocational training • heroin replacement treatment (heroin, morphine). Heroin-assisted treatment was recently shown to be of more benefit to long-time opiate injectors with unsuccessful abstinence-oriented and perhaps OST treatment histories who may have serious continuing medical problems (77). However, heroin prescribing programmes remain highly con- troversial. Such an intervention might be considered when all other treatment services have been saturated, for example, where there is universal access to methadone and buprenorphine treatment. 2.4. Management of non-opioid dependence (including cocaine and ATS) While it is estimated that there are now over 13 million injecting drug users worldwide, not all substance dependence is on opioids. It is also associated with sedatives, cocaine and ATS. It is vital that services respond to the needs of non-opioid users. HIV risk is also associated with non-opioid drugs, particularly where these drugs are injected. There are limited data on association between 14 An alpha-adrenergic agonist that suppresses withdrawal signs and symptoms. The patient may require admission, given the associated risk of significant hypotension; consequently lofexidine may be preferable. 15 Residential drug-free rehabilitation programmes of 3–15 months duration. Group or individual psychotherapy and vocational training may be available. 16 Short-term residential programmes (6–8 weeks), often based on the 12-step Minnesota model. 17 A time-limited, structured, goal-oriented psychological intervention focusing on the problems of the drug user entering treat- ment. The therapy identifies the determinants or high-risks of drug use and allows the user to relearn appropriate coping skills, leading to a healthier lifestyle; can be brief or extended (73). 18 Stimulates and enhances an individual’s resolve to change behaviour. 19 An intervention that reinforces or rewards appropriate behaviour. The reward may be in the form of vouchers for samples that test negative for drugs (74, 75). 20 Designed to integrate interventions into a comprehensive approach. Elements include: individual counselling, CBT, motiva- tional interviewing, family education groups, urine testing and participation in 12-step programmes (76). 179 HIV/AIDS TREATMENT AND CARE FOR INJECTING DRUG USERS ATS use and high-risk sexual behaviour. At present there is no proven effective substitution therapy for non-opioid drugs, although dexamphetamine has been prescribed for amphetamine users in Aus- tralia and the United Kingdom (78). Bupropion and sustained-release methylphenidate are among a number of promising pharmacotherapies for the treatment of methamphetamine dependence. With the exception of detoxification for opioids and heroin prescribing, the range of treatment options is similar to those shown above for services treating opioid IDUs not on OST. There are however, some further considerations in relation to medical management and psychological inter- ventions: • Acute medical detoxification from cocaine and ATS focuses on relief of psychiatric withdrawal symptoms. • Acute withdrawal problems are typically dealt with in the first three to five days post-cessation; however, they can last up to two weeks, particularly in individuals with comorbid medical or psychiatric problems. • Detoxification should only form one part of a broader drug-dependence treatment. • ATS use in general (and methamphetamine use in particular) has been associated with poor treatment engagement and high rates of drop-out and relapse. 2.4.1. Symptoms and medications • Agitation and acute depression often follow cessation of cocaine or ATS and may require a mi- nor tranquillizer such as diazepam for a short period. • Psychotic symptoms, such as paranoia, may require antipsychotic medication. • Palpitations and restlessness may benefit from the use of propranalol (a beta blocker), which has been shown to improve treatment retention and decrease cocaine use among those with severe withdrawal symptoms (79). • Drugs that stimulate the dopamine system in the brain can help manage depressive symptoms and severe craving in heavy cocaine users. Amantadine, a Parkinson disease medication, may prove beneficial (80), while desipramine, a tricyclic antidepressant, can increase the availabil- ity of dopamine (81). Desipramine has been associated with cardiac rhythm disturbances and should be used cautiously in patients also using methadone. 2.4.2. Relapse prevention Following detoxification, medications useful for relapse prevention include those that reduce eu- phoria and limit craving, such as topiramate, an anticonvulsant (82), or that make the high less pleasant and produce anxiety, such as disulfiram (83). Close monitoring of signs for possible drug interactions should be taken when prescribing these medications in conjunction with ARVs. • Topiramate is cleared through renal elimination; therefore, caution should be exercised in cases of renal or hepatic insufficiency. • Although there are no reports of significant interactions with ARVs, topiramate is susceptible to clinically relevant drug interactions due to induction of its metabolism (84). • Interactions can occur between disulfiram and compounds that utilize the cytochrome p450 enzyme system (85). • There are reported interactions between disulfiram and the liquid form (but not the capsule form) of lopinavir/ritonavir, which contains ethanol and thus precipitates a reaction (86). The capsule form is thus the preferred option. 2.4.3. Other interventions Although there is no proven substitution therapy available for stimulant injectors, drug dependency services have ongoing contact with these patients, which provide opportunities for adherence sup- port, often through psychological interventions, and in some desipramine cases the possibility of dispensing medication. The psychological interventions mentioned above (section IV.2.3) also have proven benefits in the treatment of cocaine and ATS dependence. CBT, the community reinforce- ment approach, contingency management and 12-step programmes have all demonstrated efficacy in treatment of cocaine and ATS dependence. 180 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 3. Management of HAART in IDUs with HIV/AIDS • Initiation of ART is rarely an emergency. • Patients should be well informed and motivated, while potential barriers to adherence should be addressed. • Health care providers should give written information (in appropriate language and consistent with literacy levels) about ART to all patients and their families prior to initiation of treatment. • Preparations for receiving ART should include: ° substance dependence treatment ° stabilization of living conditions ° treatment of psychiatric disorders ° stabilization of serious medical conditions. Initiation of ART for HIV-infected IDUs should follow the current recommendations for initiation of ART in other HIV-infected patients; see Table 1. (For further details, please refer to Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents.) Table 1. Recommendations for initiating ART in PLHIV WHO clinical stage CD4 cell count Recommendation 1 <200/mm3 Treat 200–350/mm3 Consider treatment 2 <200/mm3 Treat 200–350/mm3 Consider treatment 3 <350/mm3 Treat 4 Regardless of CD4 count Treat While most clinicians regard CD4 counts as the more important indicator for initiation of treatment, viral load monitoring is useful, though not necessary, with >100 000 ribonucleic acid (RNA) cop- ies/ml being the threshold level for ART. A fundamental part of initiating treatment is ensuring that the patient is an active and a responsible participant in the plan. The key to effective HAART and treatment of any comorbidities is a careful assessment and education of the patient, leading to the development of an individualized treatment plan to maximize adherence. It is crucial that treatment plans be designed collaboratively by staff, patient and (where appropriate) family. All predictable potential barriers to successful treatment adherence should be addressed with this plan. The active participation of patients in their own treat- ment encourages closer cooperation with health care workers and better feedback on the effects of treatment. 3.1. Choice of HAART regimen Selection of ARV drug regimens should include individual patient variables, such as comorbidities and other co-conditions. For IDUs, there are specific issues that should be identified during patient evaluation. • IDUs may continue to actively use illicit drugs and may not be in OST. • Comorbidities are very common, in particular mental health problems such as depression and alcohol dependence. • Coinfections such as hepatitis C virus (HCV), HBV and TB are common. • Drug interactions are more complex, for example, ARV interactions with illicit drugs or substi- tution treatments. • IDUs may be homeless or otherwise difficult to contact. 181 HIV/AIDS TREATMENT AND CARE FOR INJECTING DRUG USERS • Adherence can be a more difficult issue with IDUs, particularly if they are receiving treatment for HCV or TB. The above considerations have implications for the choice of treatment regimen. Issues of HAART for IDUs include the following (4): • Women who wish to become pregnant should not be prescribed efavirenz (EFV). • Active hepatitis may be exacerbated more by nevirapine (NVP) than other drugs. • Hepatoxicity may be due to direct drug toxicity or as a consequence of immune reconstitution syndrome (IRS) in patients with hepatotrophic viruses. • For IDUs with hepatitis B coinfection, lamivudine (3TC) and tenofovir (TDF) are active against both infections. • In alcohol users, the potential for pancreatitis is increased with didanosine (ddI). • In alcohol users, the potential for peripheral neuropathy is increased with stavudine (d4T). • In the presence of TB, EFV is preferable (abacavir (ABC) can be an option). • Rifampacin for TB treatment should not be administered to patients receiving protease inhibi- tors (PI) (due to possible drug-induced hepatitis); however, rifabutin can be used (refer to Pro- tocol 4, Management of tuberculosis and HIV coinfection). • Intolerance of non-nucleoside reverse transcriptase inhibitor (NNRTIs) due to liver disease (HCV, HBV) or psychiatric disorders may require the use of a PI or ABC in first-line regi- mens. • All possible drug interactions with other medications should be addressed. 182 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 3.2. Recommended HAART regimens for IDUs Recommended regimens for IDUs are summarized in Table 2. Table 2. HAART regimens for HIV-infected IDUs in different clinical situations Treatment situation First-line preferential First-line alternativesa Second-line preferred Second-line alternatives Injecting drug use without other significant clinical comorbidities or co-treatments, but needs ART ZDVb + 3TC (or FTC)c + EFVd TDF or d4T can replace ZDV. ABC or NVP or TDF can replace EFV. ABC + ddI+ LPV/re (or SQV/r) NFV can replace LPV/r or SQV/r. ZDV or d4T can replace ABC if none were used in first line. EFV or NVP can replace ABC or ddI if none of either was used in first line. Injecting drug use with HBV/HIV, with indications for treating HBV and using ART ZDV+3TC (or FTC) + EFV TDF or d4T can replace ZDV. ABC, NVPf or TDF can replace EFV. ABC + ddI+ LPV/r (or SQV/r) and maintenance of 3TC and/or TDF NFV can replace LPV/r or SQV/r. ZDV or d4T can replace ABC if they were not used in first line. EFV or NVPf can replace ABC or ddI if they were not used in first line. Injecting drug use with TB/HIV using TB regimens with rifampicin (RMP) and needs ART ZDV+3TC (or FTC) + EFV TDF or d4T can replace ZDV. ABC or NVPf or TDF can replace EFV. ABC + ddI+ LPV/r + RTVg (or SQV + RTV) Maintain the PIs and substitute rifam- picin for rifabituin in TB regimen, with adjustments in ARV dose if needed. Injecting drug use with HCV/HIV using concomitant anti-HCV treatment and ART ZDV+3TC (or FTC) + ABCh, i d4T or TDF can replace ZDV. TDF can replace ABC. Consult with a specialist with experience in the management of both diseases. – a Boosted PIs can be used as part of the first line ART in combination with two nucleoside or nucleotide reverse tran- scriptase inhibitors (NRTIs) when EFV is contraindicated. b Methadone can significantly increase zidovudine (ZDV or AZT) concentrations. While the clinical significance is un- clear, adverse events should be monitored. c FTC (emtricitabine) is interchangeable with 3TC. d EFV can significantly decrease methadone concentrations (60%) and methadone withdrawal is common. Significant methadone dose increase (e.g. 50%) is usually required. e LPV/r (lopinavir/ritonavir) has been reported to cause methadone withdrawal and increased methadone dosage may be required. f NVP can substitute for EFV in this situation, if no other options are available, but should be carefully monitored. g LPV/r with extra dose of RTV (LPV/r + RTV). Refer to Protocol 4, Management of tuberculosis and HIV coinfection. h ABC can mildly decrease methadone levels. Although risk of opioid withdrawal is low and dosage adjustments un- likely, some patients might require a methadone dose increase. i Simplification strategy (start triple NRTIs and HCV therapy after the improvement of immunologic and virologic parameters with an induction phase with a NNRTI-based regimen). Refer to the Protocol 6, Management of hepatitis C and HIV coinfection. Switching to second-line HAART should be done in case of treatment failure, which is measured clinically and immunologically. (Please refer to Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents.) Treatment failure (occurrence of a new opportunistic infec- 183 HIV/AIDS TREATMENT AND CARE FOR INJECTING DRUG USERS tion or malignancy, recurrence of a previous opportunistic infection and the onset of WHO Stage III conditions) should be differentiated from immune reconstitution inflammatory syndrome (IRIS), which can occur in the first three months after initiation of HAART. The latter is an inflammatory response to previously subclinical opportunistic infections in advanced immunodeficiency. The op- portunistic infection in IRIS should be treated as usual. 3.3. Hepatotoxicity of ARVs • NRTI hepatotoxicity is not a frequent adverse effect but has been reported with ZDV, ddI and d4T in the form of liver enlargement, liver enzyme abnormalities and/or lactic acidosis. ABC and 3TC have also been implicated but to a lesser degree. Regimens containing ZDV/ddI and d4T/ddI combinations should be avoided. • NNRTI hepatotoxicity has been associated mainly with NVP but has also been reported with EFV. NVP should be avoided if possible. Women and patients with high CD4 counts are at higher risk of these hepatic events (including NVP deaths). • PI hepatotoxicity is often mild. However, high dose ritonavir (>1000 mg/day) appears more po- tentially hepatotoxic than other PIs. Unlike the hepatotoxicity associated with NNRTIs, which occurs in the first weeks of treatment, that associated with PIs can appear at any time during treatment. PI dosing is difficult in patients with decompensated liver disease and drug level monitoring may be helpful. • Despite the common association of hepatotoxicity with HAART, almost 90% of HIV-infected patients, regardless of whether they are coinfected with hepatic viruses, will tolerate HAART without severe liver toxicity (87). 3.4. Considerations for IDU patients with hepatitis C/HIV coinfection All IDUs with hepatitis C should be considered for treatment with pegylated interferon and ribava- rin. The sustained response rate for this treatment has been reported as 11–29% for genotype 1 and 43–73% for other genotypes (88–90). Factors influencing response include CD4 count, HIV viral load and the presence of cirrhosis. Treatment is best provided at a high CD4 count before the need for HAART arises. If HAART intervention is required, the patient should be stabilized on therapy with a CD4 count of >200cells/mm3 before anti-HCV treatment is initiated. (For further information please refer to Protocol 6 on Management of hepatitis C and HIV coninfection.) The side-effects of hepatitis treatment have the potential to destabilize a successful HAART re- sponse. Consideration should be given to anti-HCV treatment at a substance dependency centre or HIV/AIDS centre where OST and HAART may be directly administered. A further advantage of this approach is that the patient can be monitored clinically, by the psychiatric/psychological sup- port staff in the drug dependence service, especially since depression is one of the more serious side-effects of interferon (91). 3.5. Considerations for IDU patients with TB/HIV coinfection The treatment of TB and HIV coinfection in IDUs is complex; however, it can still be managed effectively (92). Data supporting specific treatment recommendations are incomplete and research is urgently needed in this area. Please refer to Tables 2 (section IV.3.2. above) and 5 (see section IV.4.4.4.) for specific issues in HAART for IDUs with active TB. Methadone dosage needs to be considered in the TB treatment of IDUs. As rifampicin is a potent inducer of cytochrome P450, it can lead to a reduction in circulating methadone levels, possibly requiring a substantially increased dosage. As buprenorphine is also metabolized by the cytochrome P450 pathway, it is suspected that rifampicin has a similar major impact on the buprenorphine level. Rifampacin also accelerates the metabolism of PIs. There are no reported interactions between methadone and rifabutin, so rifabutin may be an alternative in combination with PIs (93). (See Table 5 in section IV.4.4.4. ) 184 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 3.6. Adherence Adherence is an important determinant of a successful response to HAART, since incomplete ad- herence has been associated with early emergence of ART resistance (94, 95), virological failure and subsequent immunological and clinical failures (96). Adherence rates over 95% are required to achieve optimal viral suppression (97). If drug resistance develops, drug resistant viruses can be transmitted, necessitating revised treatment regimens (96, 98). The relationship between non-adherence and plasma HIV RNA levels is clear, but not proportion- ate: a small amount of non-adherence yields large losses of viral control. One study showed that a 10% decrease in adherence was associated with a doubling of the HIV RNA level (99). In addition, CD4 count can decrease with adherence under 90% (100). The need for more than 95% compliance to treatment has allowed an incorrect view to develop that IDUs are poor candidates for HAART. IDUs are disproportionately and wrongly excluded from HIV/AIDS treatment, particularly HAART. Studies indicate that: • the proportion of non-adherent individuals is similar in non-IDUs and IDUs on OST (101, 102); and • rates of ARV resistance are no higher in IDUs than non-IDUs. IDUs receiving stable care from experienced staff with adequate support can adhere to HAART and have clinical outcomes equivalent to those of HIV patients who do not use drugs (9, 10, 94). In particular, consistent participation in methadone maintenance programmes has been shown to be associated with a higher probability of HAART use and better adherence to it (1, 3, 11, 24, 44, 48–50, 103). 3.6.1. Factors influencing adherence Adherence to HAART can be influenced by many types of factors. Medical factors are: • toxicity and side-effects of ARVs or interactions with other medications or substances • hepatotoxicity, which is much higher among IDUs than non-IDUs21 • severe opportunistic infections • comorbid psychiatric disorders, including depression (39, 104).22 Personal factors are: • continuing or relapsed drug use (68) • concurrent problematic alcohol use or multiple drug dependence • lack of prospects and motivation • major life events and crises • side-effects of ARVs or perception of same (108, 109) • expectations of treatment success (by patients and providers). Health-care-service-related factors are: • stigmatization and discrimination in health care settings (110) • perception of unfriendly and poor-quality health services (102) • availability and accessibility of treatment services for drug dependence (51, 111) • poor or non-existent links between services • lack of continuity of care • providers’ belief that IDUs are unable to adhere to HAART (110). 21 Please see Protocols 6 and 7, Management of hepatitis C and HIV coinfection and Management of hepatitis B and HIV coin- fection. 22 Depression is also a determinant of clinical progression independent of adherence (39, 105–107). 185 HIV/AIDS TREATMENT AND CARE FOR INJECTING DRUG USERS Social factors are: • homelessness and lack of family or community support • unemployment • stigmatization and discrimination • restrictive legislative and policies. 4. Monitoring of IDUs under treatment 4.1. Monitoring of substance dependence treatment Monitoring the effectiveness of substance dependence treatment can be achieved through a number of means. • Care planning is particularly informative; regular review by the case manager or physician is instrumental in achieving better outcomes. • Care plans can set out short-, medium- and long-term goals; monitoring them indicates the de- gree of progress. • Patient records are an essential element for documenting good practice and for informing evalu- ation and cover information on: o assessment results o treatment plans o daily dosages o side-effects of prescribed medicines o regimens used (including take-home doses) o medical care o psychological and psychiatric care o social care o laboratory findings o clinical observations o programme compliance observations o circumstances of leaving/terminating treatment o an agreement to terminate treatment o arrangements for after-care. • The use of standardized instruments, such as the ASI (see Annex 1), allows progress to be moni- tored more formally. • Screening for illicit drug use using urine, breath, saliva, blood or hair analysis can indicate the degree of response to the treatment. • Drug screening is not a prerequisite; it should be undertaken with informed consent and should not be used to terminate treatment. 4.2. Monitoring of laboratory indicators with regards to HIV/AIDS IDUs with HIV infection should be carefully monitored during the course of HIV infection to ensure continuum of care. Laboratory indicators, such as CD4 cell count and viral load should be monitored regularly whether or not a patient has started ART. For further information on patient monitoring please refer to Protocol 1 Patient evaluation and antiretroviral treatment of adults and adolescents. 4.3. Mangement of ARV toxicity and side-effects Clinical side-effects of ARVs are relatively common, reported in nearly 50% of patients (112), and are a leading cause of poor adherence to drug regimens (113). Management of possible side-effects is most effective when all staff are aware of the risk of side- effects in order to intervene early, and the patient understands the cause and nature of ARVs side- effects, and the importance of reporting them early in order to: 186 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION • organize adherence support • adjust treatment regimens so they are safe, effective and acceptable • minimize the risk of drug resistance because of poor adherence. Early in the course of HAART, mild side-effects such as headache, nausea, diarrhoea and fatigue are common. They may often be managed simply with support, reassurance and symptomatic treatment such as analgesics or anti-diarrhoeal agents. These interventions are very useful in helping individu- als to cope with side-effects without stopping or changing their HAART regimens. Side-effects can vary from mild to very serious and can affect many organ systems. Major side-ef- fects of ARVs by drug class and organ system (114) are shown in Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents. Careful clinical assessment is required to exclude other possible causes of signs and symptoms that might be mistaken as ARV side-effects, for example opioid withdrawal syndrome is characterized by headaches, anxiety, diarrhoea and headaches. In cases where the symptomatic measures are not sufficient or the toxicity is too severe it may be necessary to replace a side-effect-causing ARV drug with another ARV drug within the existing HAART regimen (please see Table 2 above). Please also see Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents. 4.4 Drug-drug interactions in IDUs Health care providers should counsel every patient on all possible interactions of ARVs with other drugs administered, including substitution therapy drugs (see Table 3), illicit/recreational drugs and medications for TB, HCV, HBV and other opportunistic infections. Awareness of interactions and reporting and management of symptoms is critical for the patient’s well-being, treatment adherence and effectiveness, and management of drug interactions. 4.4.1. Methadone and ARVs • Methadone is metabolized in the liver by several cytochrome P450 (CYP) enzymes (especially CYP3A4). Its level may drop when used in conjunction with drugs that induce cytochrome enzymes, and an increased dosage may be required. When used in conjunction with drugs that inhibit cytochrome enzymes, its level may increase and a dose reduction may be needed. • Methadone itself inhibits the metabolism of ZDV, thus possibly elevating ZDV levels by as much as 43%; although no empiric dose reduction is currently recommended, signs of toxicity should be closely monitored (115). • Methadone can decrease ddI levels by up to 60%, leading to ddI underexposure, incomplete viral suppression and development of resistance. • Nevirapine, efavirenz and ritonavir decrease methadone concentrations (116, 117) and produce withdrawal symptoms. • NNRTIs are significantly more likely to interact with methadone than PIs, therefore IDUs on OST require careful monitoring. • The PI LPV/r has also been shown to produce an increase of methadone metabolism necessitat- ing dosage increases in some cases (118). 187 HIV/AIDS TREATMENT AND CARE FOR INJECTING DRUG USERS Table 3.

If methadone trough levels are normal, suspect that problem is ZDV toxicity. NNRTIs Efavirenz (EFV) Methadone concentrations significantly decreased (60%). Methadone withdrawal common. Significant methadone dose increase (50%) usually required. Unknown Observe closely for signs of methadone withdrawal and increase dosage as necessary. Symptoms of withdrawal may be delayed for up to 2 or 3 weeks. 188 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Nevirapine (NVP) Methadone concentrations significantly decreased (46%). Methadone withdrawal common. Methadone dose increase (16%) necessary in most patients. None reported In a case series of chronic methadone recipients initiating nevirapine, there was a need for 50% to 100% increases in the daily methadone doses to treat opioid withdrawal. Withdrawal symptoms generally occur between 4 and 8 days after starting nevirapine, although they may be delayed for up to 2 or 3 weeks. PIs Lopinavir/ritonavir boost (LPV/r) Methadone levels de- creased (26–53%). Withdrawal might occur, requiring dosage increase. Side-effects may mimic withdrawal. None reported Methadone withdrawal reported. May require increased methadone dose. Nelfinavir (NFV) May decrease methadone levels (29–47%). Clinical withdrawal rarely reported.

Saquinavir 1600 mg, ritonavir 100 mg (SQV/r) Saquinavir 1400 mg, ritonavir 400 mg (SQV + RTV) Methadone levels slightly reduced (SQV/r 1600/100 by 0–12%, SQV + RTV 1400/400 by 20%). No reported withdrawal. Methadone dosage adjust- ments may be necessary. Unknown Methadone dose adjust- ments may be necessary; requires ongoing monitor- ing. a The methadone levels are based on trough levels measured in plasma 24 hours after ingestion of the last dose. For a useful evaluation of the methadone level, patients should have been on their doses for at least five days before testing. Source: adapted from WHO. Leavitt et al. (4,104). Opioid metabolization can be inhibited or induced by concomitant PIs, so patients should be monitored for signs of toxicity. The withdrawal symptoms generally occur within 4 to 10 days of ARV initiation. Withdrawal symptoms should be monitored clinically and dosage increases of 10 mg increments from days 8–10 should allow this problem to be managed. The required increase in methadone is not as great as expected from pharmacokinetic data. Clinically, some of the potential interactions indicated above do not require a change in dose or medication. Practically, the use of NNRTIs does require an often significant dosage adjustment of methadone.

Methadone and other medications Interactions between some medications used to treat comorbidities such as psychiatric disorders or TB associated with HIV in IDUs, and methadone or ARVs have also been reported and are indicated in Table 4. An up-to-date drug interaction database would doubtless prove useful to prescribing clinicians. Table 4.

A methadone dosage in- crease may be required. Consider using valporic acid as an alternative Some interactions (refer to Protocol 1, Patient evalu- ation and antiretroviral treatment in adults and adolescents). Monitor for toxicities and dose adjustments. 190 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Other medications Use Interaction with methadone Interaction with ARV medications Fluconazole Antifungal Increased methadone levels (35%). Clinical significance unknown, although cases requiring dose reduction reported. No signs of methadone toxicity reported. Other azole antifungal antibiotics may potentially influence opioid toxicity. e.g. itraconzale, ketocon- azole, voriconazole. Potential for bi-directional inhibition between some azole antifungal antibiotics and PIs. Monitor for toxici- ties and dose adjustments. Toxicity and anti-fugal outcomes observed with NNRTIs. Refer to Protocol 1, Patient evaluation and antiretrovi- ral treatment in adults and adolescents. Interferon-α + ribavirin Anti hepatitis C treatment Side-effects can mimic opi- oid withdrawal symptoms and methadone dose is often increased. In a study of HCV patients concomitantly receiving methadone and peginter- feron-alfa 2a methadone levels increased 10-15%. Clinical significance un- known. Patients should be monitored for signs and symptoms for methadone toxicity. Hepatitis C infection can aggravate the hepatotoxic- ity of several ARV regi- mens. (Refer to Protocol 6, Management of hepatitis C and HIV coinfection.) Phenobarbital (barbiturate) Anticonvulsant, sedative Decreases methadone levels, often sharply. May cause withdrawal. A methadone dosage in- crease may be required. Barbiturates such as pheno- barbital are potent inducers of CYP3A4. Clinicians should consider avoiding concurrent administration of other potent inducers (e.g. EFV and NVP) in patients misusing barbitu- rates. May decrease NFV con- centrations. Phenytoin Anticonvulsant Decreases methadone levels, often sharply. May cause withdrawal. A methadone dosage in- crease may be required. Some interactions (refer to Protocol 1, Patient evalu- ation and antiretroviral treatment in adults and adolescents.) Monitor for toxicities and dose adjust- ments. Rifabutin Anti-mycobacterial treat- ment of pulmonary TB No change in methadone levels. Mild narcotic withdrawal symptoms. Some interactions (refer to Protocol 1, Patient evalu- ation and antiretroviral treatment in adults and adolescents) but rifabutin may be a preferred option for the treatment of pulmo- nary TB as an alternative to rifampicin. Monitor for toxicities and dose adjust- ments. 191 HIV/AIDS TREATMENT AND CARE FOR INJECTING DRUG USERS Other medications Use Interaction with methadone Interaction with ARV medications Rifampicin (Rifampin) Rifampin/isoniazid Treatment of pulmonary TB Possibly severe decrease in methadone levels (33–68%). May induce methadone withdrawal. A methadone dose increase may be required. PIs contraindicated. Rifampin should not be co-administered with LPV, NFV, SQV. Rifabutin may be a poten- tial alternative, but not in combination with SQV. Sildenafil Erectile dysfunction agent Not reported No effect of sildenafil on PIs. Ritonavir increases silde- nafil 10-fold. Saquinavir increases silde- nafil 3-fold. Use cautiously and monitor for adverse effects. Source: Leavitt et al., McCance-Katz et al. (104,111). 4.4.3. Buprenorphine and ARVs Buprenorphine and ARV interactions are less well researched than methadone interactions. Morphine derivatives and opioid antagonists such as naltrexone should not be used with buprenor- phine due to its partial antagonist effects. Elevations in liver enzymes (AST and ALT) have been reported in individuals receiving buprenorphine. There appears to be a mild elevation in liver en- zymes in patients with hepatitis who receive buprenorphine long-term. As buprenorphine is me- tabolized by the cytochrome P450 3A4 enzyme system, other medications that interact with this system should be used with caution. While in vitro evidence suggests that buprenorphine is metabolized by the cytochrome P450 en- zyme (3A4 isomer) and would be affected in a similar way to methadone by enzyme inducers such as NVP, EFV and RTV, the evidence is not available from clinical trials to support this. To date, limited data exists on interactions between buprenorphine and ARVs; however, in examining both EFV and ZDV, the following observations have been made: • Administering EFV with buprenorphine lowers buprenorphine levels but does not seem to pro- duce clinical withdrawals (119). • ZDV with buprenorphine does not precipitate withdrawals, and ZDV levels do not decrease as they have been seen to do with methadone (120). Other potential interactions include those with: • cytochrome P450 3A4 inhibitors such as fluconazole and macrolide antibiotics • inducers such as phenobarbital, carbamazepine, phenytoin and rifampicin • sedatives such as benzodiazepines. Supervision of buprenorphine medication permits DOT with HAART, although in some cases, pa- tients may only require buprenorphine doses every second or third day. Clinicians should remain aware of the potential for the sublingual buprenorphine to be crushed and injected, as this method has been linked with some cases of hepatitis in IDUs (83). 4.4.4. Illicit/recreational drugs and ARVs Interactions between ARVs and psychoactive substances used for non-medical purposes are possi- ble and may have serious clinical consequences in terms of HAART efficacy or drug toxicity (121). PIs and NNRTIs can inhibit or induce the cytochrome P450 system in the liver, which is responsible for the metabolism of benzodiazepines, amphetamines and opioids. 192 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 4.4.4.1 Benzodiazepines • Benzodiazepines that are primarily dependent on CYP3A4 for metabolism – midazolam, tri- azolam, alprazolam and flunitrazepam – are likely to be affected by PIs and those ARVs that cause inhibition of CYP3A4, causing drowsiness, confusion and paradoxical aggression. • NVP, which can induce CYP3A4, may lead to withdrawal symptoms and encourage dose esca- lation in benzodiazepines. • The benzodiazepines where CYP3A4 metabolism plays a minor role include lorazepam, oxaz- epam, temazepam and diazepam, for which no interactions have been reported. 4.4.4.2 Cocaine Cocaine may be used either by itself or in combination with other recreational drugs. Understanding the impact of cocaine use on HAART is important for successful treatment (122). • The metabolism of cocaine to norcocaine (an active hepatotoxic metabolite) occurs at CY- P3A4. • PIs and other drugs that inhibit CYP3A4 activity can lead to a fatal cocaine overdose. • NVP, which induces this enzyme, can cause a build-up of a potentially hepatotoxic metabolite. 4.4.4.3 Amphetamine, methamphetamine and 3, 4 methylenedioxymethamphetamine (MDMA) • These have similar metabolism mainly through the CYP2D6 pathway. • Certain PIs, especially ritonavir may cause inhibition of CYP2D6 and therefore toxicity. A fatal MDMA/ritonavir interaction has been reported (123). 4.4.4.4 Opioid-based drugs, such as heroin, codeine, morphine and other analgesics Interactions with ARVs are similar to those described for methadone. Thus, NNRTIs and some PIs may result in opioid withdrawal and loss of analgesia. 4.4.4.5 Tetrahydrocannabinol (THC) (main active component of cannabis products) • Information on potential interactions with ARVs is limited. • A study looking at the effects of THC on HAART medication showed no clinically significant changes in the plasma levels of indiavir (IDV) or NFV (124). • Administration of potent CYP3A4 inhibitors (for example, PIs and EFV) might result in greater effect and longer duration of THC. 4.4.4.6 Other psychoactive drugs that may be used non-medically • Gamma-hydroxybutyrate (GBH, liquid X) toxicity has been reported in conjunction with RTV and SQV (125). • Ketamine might inhibit CYP3A4 and increase side-effects of antiretroviral treatment. • Phencyclidine23 might be metabolized primarily by CYP3A4 and therefore PIs may increase the risk for phencyclidine toxicity. Table 5 briefly summarizes available and postulated data on drug and ARV interactions. It also gives an indication of the primary site of metabolism within the liver; however, it must be recognized that there are significant numbers of other enzyme systems involved with each drug. The lack of research in this area means that some of the interactions or effects are postulated on the basis of knowledge of enzyme substrates involved in metabolism of various drugs. 23 Phencyclidine is commonly known as “PCP” or “angel dust”, as the same acronym is also known as Pneumocystis jirovecii pneumonia and used in this and other protocols, in order to avoid confusion, phencyclidine is written out in this protocol. 193 HIV/AIDS TREATMENT AND CARE FOR INJECTING DRUG USERS Table 5. Interactions of illicit drugs and ARVs Drug Primary metabolism site Interaction Recommendation Amphetamines CYP2D6 RTV ↑ levels ⇒ toxicity. Do not prescribe RTV or lopinavir/ritonavir even in low doses if patients report amphetamine use. Barbiturates CYP3A4 Barbiturates such as pheno- barbital are potent inducers of CYP3A4. Consider avoiding concurrent administration of other potent inducers (e.g. EFV and NVP) in patients misusing barbitu- rates. Benzodiazepines CYP3A4 involved with midazolam, triazolam, al- prazolam & flunitrazepam PIs ⇒ over-sedation. NVP ⇒ withdrawals. Avoid concurrent use of alprazolam, midazolam and triazolam with all PIs and EFV. Cocaine CYP3A4 PIs and EFV ↑ levels ⇒ overdose. NVP⇒hepatotoxic me- tabolite. Monitor for increased hepato- toxicity. Codeine UGT 2B7 PIs ↑ or ↓ metabolism ⇒ possible overdose ⇒ loss of analgesia. Interactions with ARVs are similar to those described for methadone. Thus, NNRTIs and some PIs may result in opioid withdrawal and loss of analge- sia. Should be monitored. Heroin Plasma NFV, RTV ⇒ withdrawal. No clinically significant interactions reported however interactions with ARVs are similar to those described for methadone. Thus, NNRTIs and some PIs may result in opioid withdrawal and loss of analgesia and clinicians should monitor. MDMA (ecstasy) GHB (gamma-hydroxy- butyrate) CYP2D6 RTV ↑ levels ⇒ toxicity. Do not prescribe PIs even in low doses if patients report MDMA or GHB use. MDMA–ritonavir interactions can be fatal. Morphine UGT 2B7 NFV, RTV ⇒ withdrawals, loss of analgesia. Interactions with ARVs are similar to those described for methadone. Thus, NNRTIs and some PIs may result in opioid withdrawal and loss of analgesia. Clinicians should monitor. Phencyclidine CYP3A4 PIs, EFV ⇒ toxicity. Monitor for phencyclidine toxicity. THC CYP3A4 PIs may ↑ concentration. NNRTIs may ↓ concentra- tion. No clinically significant inter- actions reported. 194 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 4.5. Adherence support and monitoring Adherence support and monitoring should be part of the routine clinical care provided by all health professionals dealing with HIV-infected patients. Optimizing adherence in the first four to six months of treatment is crucial to ensure long-term immunovirological success (110). Moderate de- viations from high adherence (88–99%) during follow-up (the maintenance phase, after six months) have less severe impact. Several interventions for enhancing adherence are possible, but priority should be given to those aimed at the early months of HAART (126–130). When giving adherence counselling, health care providers have to make sure that every patient: • has emotional and practical life support • fits his/her drug regimen into a daily routine • understands non-adherence leads to resistance and treatment failure • recognizes that all doses must be taken • feels comfortable taking drugs in front of others • keeps clinical appointments • understands the side-effects of ARVs and their interactions with OST and illicit drugs • knows alarm signs and when to see a doctor about them (51). Other tactics for supporting adherence include: • treating depression to enhance adherence (61); • managing drug interactions and adjusting dosages; • dispensing medication in small amounts24 at frequent intervals to: o detect adherence problems before they lead to drug resistance; o limit treatment disruptions or misuse; • directly observing ARV treatment, particularly when linked to drug dependence treatment. 4.6. Management of acute and chronic pain (including people on OST) Pain management in opioid dependants is unnecessarily controversial. Clinicians are reluctant to prescribe adequate pain relief drugs because of: • suspicion that patients are simply drug-seeking and are exaggerating the severity of their pain; • misconceptions that methadone at its maintenance dosage is an adequate analgesic in itself for those IDUs stabilized on it; • concern that prescribing a codeine-based drug will interfere with the drug testing carried out in methadone treatment clinics; • complex interactions with ARVs, resulting in under-prescribing of analgesia; and • inadequate access to appropriate analgesics in clinics. Reluctance by clinicians can lead to the pain not being addressed adequately and patients sourcing their own drugs, perhaps illicitly. 4.6.1. Pain management in patients receiving methadone Patients do not obtain adequate pain relief from their usual daily dose of methadone, to which they have become tolerant, from which several conclusions may be drawn. • Additional analgesics should be prescribed to treat acute or chronic pain in HIV-infected IDUs who are on methadone maintenance treatment, starting with mild analgesia and progressing based on response.25 • Pethidine and piroxicam should not be administered with ritonavir or LPV/r. • Alternative options (acupuncture, massage, etc.) for pain relief should be considered, particu- larly for chronic pain. 24 Once-daily options, low pill burden and the use of fixed-dose combinations (FDCs) may be of benefit in the early stage of treatment. Please refer to Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents. 25 Note that, as with methadone, NNRTIs and PIs will alter the metabolism of opioid based analgesics. Patients on long-term pain medication may require more of their opioid-based pain relief, just as they would require an increase of methadone. 195 HIV/AIDS TREATMENT AND CARE FOR INJECTING DRUG USERS • Careful monitoring of IDUs on ARVs and continuing pain medication is required, as dose ad- justments or a change of timing may be necessary. • Clinicians should treat IDUs on methadone for pain the same way they do non-methadone pa- tients.26 4.6.2. Pain management in patients receiving buprenorphine Further clinical studies are needed of patients treated for pain while on buprenorphine. Like metha- done, buprenorphine has strong analgesic properties; however, the once-daily dosage for treatment of substance use is not sufficient to sustain pain relief. Therefore: • Patients on buprenorphine needing pain relief should first be treated with a non-opioid analgesic when appropriate; a temporary increase in buprenorphine dosage may be sufficient. • If acute pain is not relieved by non-opioid medications or an increase of buprenorphine, more aggressive pain management should be undertaken, including short-acting opioid pain relievers. • When patients on buprenorphine require other opioid treatment for pain, the following should be borne in mind: ° Morphine should not be prescribed. ° Buprenorphine should be discontinued while other opioid pain medication is being taken. ° Higher doses of short-acting opioid pain medication may be needed to achieve analgesia until the buprenorphine clears the body, when they should be decreased. ° Buprenorphine should not be restarted until an appropriate period after the last dose of the opioid analgesic, given its half-life. ° Non-combination opioid analgesics are preferable to avoid toxicity and other side-effects, and for easier dosage. ° Patients with chronic pain who do not respond to increased buprenorphine and continually require additional analgesia may need to be transferred to methadone treatment (131, 132). For further information on pain management, refer to Protocol 3, Palliative care for people living with HIV. 26 For example, a woman on methadone who is in labour will require pain relief in exactly the same way as any other preg- nant woman. 196 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION V. Suggested minimum data to be collected at the clinical level The suggested minimum data to be collected is important in the development of key indicators on access of IDUs to treatment and its success. Such indicators assist managers in decision making on ways to strengthen and expand these services to all those in need. The following data should be collected at each clinical facility on a regular basis (e.g. monthly, quarterly or semi-annually): • number of HIV patients (“seen for care” – this will be the denominator for the data below); • number of IDUs among all HIV patients: ° number of HIV-infected active IDUs (having injected in the past four weeks); ° number of HIV-infected former IDUs (not having injected in past the four weeks); • number of IDUs eligible for ART (CD4 <350 cells/mm3): ° number of active IDUs eligible for ART (having injected in the past 4 weeks); ° number of former IDUs (not having injected in the past four weeks) eligible for ART; • number of HIV-infected IDUs receiving HAART: ° number of active IDUs receiving HAART; ° number of former IDUs (not having injected in the past four weeks) receiving HAART; • number of HIV-infected IDUs on OST: ° number on methadone; ° number on buprenorphine; • number of IDUs on OST and HAART; and • number of HIV-infected IDUs who have died including cause of death (e.g. HIV/AIDS related mortality or non-HIV/AIDS related mortality such as accident, overdose or suicide). In addition, it may be useful to collect data on access of IDUs to other treatment (hepatitis C, hepa- titis B and TB coinfections) for IDUs. Please refer to the following protocols for information on what data should be collected on these coinfections: Protocol 4 Management of tuberculosis and HIV coinfection, Protocol 6 Management of hepatitis C and HIV coinfection, and Protocol 7 Man- agement of hepatitis B and HIV coinfection. 197 HIV/AIDS TREATMENT AND CARE FOR INJECTING DRUG USERS ANNEX 1 ASI6 C © 2004 University of Pennsylvania 1 ASI6, Alterman, A.I. et al. © University of Pennsylvania.

The main types of drugs used; local names, etc. should be established to construct a list of drugs appropriate to the local con- text. Certain drugs are also used in the treatment of drug related problems (most commonly methadone, buprenorphine and tranquilisers, but also other opioids and other drugs) and, where these drugs are commonly used in this way, should be dealt with separately. Prescribed drugs (such as methadone) should be defined in an understandable way; for example, “Methadone given (sold) to you by a doctor as part of your treatment”. Some drugs are commonly used in combination with others. These combinations should be included (e.g. heroin and cocaine together). 211 HIV/AIDS TREATMENT AND CARE FOR INJECTING DRUG USERS Annex 3.

Epidemiology and natural history of HCV in HIV infection In Europe, the prevalence of hepatitis C virus (HCV) infection in HIV-infected patients is particu- larly high – and still rising, in contrast to the rest of the world. Yet only a minority of HCV/HIV- coinfected patients are treated for their hepatitis. The compounding effect of coinfection makes the care for these patients a major challenge. In the pre-HAART era, the late consequences of HCV-related chronic liver disease in coinfected individuals were overshadowed by AIDS mortality connected with severe immune deficiency. With the development of HAART, morbidity and mortality among HIV-infected patients have decreased significantly. The consequences of liver-related disease associated with chronic HCV infection are now far more worrying. End-stage liver disease (ESLD) is now the predominant cause of death in patients coinfected by HCV and HIV, as well as in hepatitis B virus (HBV)/HIV-coinfected patients (1), despite the availability of treatments with proven efficacy (2–5). Most patients are, however, not treated, underscoring the need for treatment guidelines. Efforts must also be made, via multidis- ciplinary health-care services, to increase the applicability and availability of treatment, especially in more vulnerable populations, including but not limited to migrants, injecting drug users (IDUs), prisoners, people with psychiatric illnesses and people who consume too much alcohol. 1. Prevalence, risk factors and transmission Worldwide about 180 million people are chronic carriers of HCV. Overlapping routes of transmis- sion for HCV and HIV result in a high frequency of coinfection in Europe. 1.1. Prevalence of HCV in HIV infection The prevalence of HCV infection in individuals infected with HIV in the WHO European Region is very high, averaging 40% and reaching 50–90% in urban areas. Data from a EuroSIDA study (see Fig. 1) shows the prevalence is higher in the eastern (47.7%) and southern (44.9%) EuroSIDA regions than in the northern (24.5%) EuroSIDA region, due to the high rates of injecting drug use in the two former regions (6). Fig. 1. prevalence of HCV in HiV-infected patients in europe Source: Rockstroh et al. (7). North: 24.5 % Central: 22.9 % South: 44.9 % East: 47.7 % 230 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION The prevalence of HCV antibodies also varies widely among HIV transmission groups, ranging from 7–8% in men who have sex with men to 60–70% in haemophiliacs and 80–90% in IDUs, the most important group (see Fig. 2) (8–12). HCV is easily transmitted among IDUs, which makes it difficult to prevent. IDU transmission occurs in several ways: • sharing needles and syringes • sharing auxiliary paraphernalia, such as cookers, straws, swabs, tourniquets and cotton • sharing drug doses from a common syringe • accidental needle-sticks. Fig. 2. prevalence of HCV antibodies in different transmission groups Source: Alter (13). The prevalence of HCV among IDUs increases with the duration of injection, as shown in Fig. 3.

(14). % P os iti ve HCV HBS ag 231 ManageMent of Hepatitis C and HiV CoinfeCtion 1.2. Primary modes of transmission The primary modes of transmission for HCV are parenteral and vertical (from mother to child); it is rarely transmitted sexually. In Europe, the most common route of transmission occurs via injecting drug use. Although sexual transmission of HCV occurs in <1% (15) of monogamous couples, there have been increasing reports of sexual transmission between men who have sex with men (MSM) (16). Household contact with an HCV-infected person has been associated with an average non- sexual transmission rate of 4% (0–11%) (17). Other risk factors for transmission of HCV include tattooing and accidental needle-sticks in medical settings (18). 1.3. Genotypes HCV exhibits a high genetic heterogeneity around the world, with six different clades or genotypes being distinguished and differing as much as 30% in their genome (see Fig. 4). Furthermore, phylo- genetic analyses can also distinguish subtypes and isolates within a particular type. Fig. 4. phylogenetic tree of HCV genotypes and subtypes Source: Francisus (19). From an epidemiological point of view, infection with genotypes 3 and 4 is more prevalent in IDUs and HIV-coinfected patients than in monoinfected patients. Acute genotype 4 infection has recently been found among MSM (16). The distribution of genotypes may differ from one region of the world to another. As genotypes have differed in their sensitivity to the standard treatment since 2005 – pegylated interferon (PEG- IFN) and ribavirin (RBV) – it is important to know the genotype of each patient and the distribution of the genotypes in each country.

(20, 21). % P os iti ve HCV HBS ag % P os iti ve HCV HBS ag 232 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 2. Access of coinfected patients to hepatitis C treatment Low percentages (0–23%) of coinfected patients have access to hepatitis C treatment (22). There may be several reasons for this: • The efficacy of PEG-IFN and RBV in treating coinfected patients was only published in 2004, and these drugs are not widely available. • A great number of patients who continue active drug use do not have access to substitution treat- ment and/or ART. • Many countries lack guidelines for diagnosis and treatment. • Evaluation of the severity of HCV disease and treatment requires high technology and skills. • Neuropsychological side-effects and toxicity are frequent during HCV treatment. • Treatment is very costly. 3. Reciprocal influences of HIV and HCV 3.1. Impact of HIV infection on HCV disease progression • Several studies have demonstrated that patients coinfected with HCV and HIV have more rapid fibrosis progression than monoinfected patients, even after taking into account age, sex and al- cohol consumption (23). • People with HCV/HIV coinfection may have quantitative and/or qualitative deficiency in their immune responses to HCV. HIV accelerates the course of HCV-associated liver disease, particu- larly in patients who are more severely immune deficient, by increasing: ° the HCV viraemia level from two- to eightfold, resulting in a significant decrease in sponta- neous recovery from acute hepatitis (24); ° the risk of mother-to-child and sexual transmission (from averages of 6% to 20% and from 0% to 3%, respectively); and ° rates of liver fibrosis (two- to fivefold), cirrhosis, decompensation, hepatocellular carcinoma (HCC) and liver-related mortality (25). • Liver disease is the leading cause of morbidity and mortality in HCV/HIV-coinfected patients in some parts of Europe, despite the suggestion that HAART, especially protease inhibitors, may decrease the severity of liver disease and the related mortality (1). • Comorbidities with hepatic consequences (drug hepatotoxicity, HBV, steatosis, alcohol or drug abuse) are frequent in coinfected patients and may increase the rate of complications associated with HCV-related liver disease. Patients with CD4 <200 cells/mm3 are those most likely to prog- ress to severe liver disease (6, 23, 25, 26). For example, HIV-infected patients with CD4 <200 cells/mm3 who drink more than 50 g of alcohol daily have a median expected time to cirrhosis of 16 years, versus 36 years for HIV-infected patients with CD4 >200 cells/mm3 who drink 50 g or less of alcohol daily (26). • Spontaneous clearance of HCV is significantly lower in HIV-infected patients than in immuno- competent patients with acute hepatitis. As HCV ribonucleic acid (RNA) might become tempo- rarily undetectable during the acute phase of HCV infection, clearance must be confirmed with a sensitive qualitative HCV RNA assay on at least two occasions six months apart (27, 28). • In profoundly immunosuppressed patients, HCV serology has occasionally been found to be falsely negative despite HCV chronic infection.1 Such false negatives have become very rare due to the high sensitivity of third-generation serology (27, 28). 1 HCV RNA testing should, therefore, be performed in people at risk, such as IDUs and MSM, and in others who may be profoundly immunosuppressed and present unexplained ALT elevation despite negative HCV serology. 233 ManageMent of Hepatitis C and HiV CoinfeCtion 3.2. Impact of HCV infection on HIV disease progression HCV has little or no effect on the response to ART or on immunological, virological or HIV-related clinical disease progression. Although HCV antibodies per se do not influence progression, infec- tion with certain multiple genotypes might do so (29). Extended follow-up in various studies indicate that patients on HAART do not have any major dif- ferences in HIV-related mortality from HCV/HIV-coinfected patients or those infected with HIV alone, particularly if ART is given (6). There is, however, an increased risk for liver disease-related morbidity and mortality in hepatitis-coinfected HIV, as well as more hepatotoxicity under ART regimens (30). 234 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION II. Identification of HCV/HIV 1. Assessment of HCV risk and diagnosis of hepatitis C in HIV-infected patients 1.1. Initial laboratory assessment of HCV status 1.1.1. Step 1: All HIV-infected patients should be tested for HCV antibodies. • For patients with acute HCV infection, it is important to bear in mind that antibodies may not be detectable for three to eight weeks following initial HCV infection. Retesting is not neces- sary if the infection was transmitted heterosexually and in the absence of other risky behaviour. For others who continue to run the risk of infection, such as active IDUs or MSM with multiple partners, testing is recommended every one to two years (31). • The presence of HCV antibodies is indicative of past or present infection. Antibodies persist indefinitely, in chronically infected patients but the antibody titres may decrease (and even dis- appear) in patients who clear HCV (either spontaneously or after antiviral treatment). • HIV infection can impair antibody responses to HCV infection (27), so a second- or third- gen- eration enzyme immunoassay (EIA) for HCV antibodies should be used in coinfected individuals. • In HCV antibody-negative HIV patients with profound immunosuppression, HCV RNA deter- mination is recommended when there are liver test abnormalities or clinical suspicion of liver disease. 1.1.2. Step 2: When testing for HCV antibodies is positive, detection of HCV RNA should be performed to confirm or exclude active replication. • HCV RNA can be detected as soon as a few days after infection. • HCV RNA can be detected by PCR (polymerase chain reaction) or by TMA (transcription-me- diated amplification). • Persistence of HCV RNA more than six months after initial infection confirms chronic hepatitis C (27, 31). • Determination of HCV RNA can be done through qualitative or quantitative assays. ° A qualitative assay is enough for diagnostic purposes. ° A quantitative assay (viral load) is important for assessment of patients who will receive HCV treatment. • High pretreatment HCV RNA levels are associated with lower rates of sustained virological response (SVR); the cut-off is generally 800 000 copies/ml (IU/ml) (32). SVR rates may reach 60% in persons with either a genotype other than 1 or 4, or genotype 1 HCV infection with an HCV RNA level ≤800 000 IU/ml after 48 weeks of PEG-IFN and RBV treatment, as opposed to only 18% for those with genotype 1 and an HCV RNA level >800 000 IU/ml. (2–5, 32). • It is important to consider that viral load is higher (0.5–1 log on average) in HCV/HIV-coin- fected individuals than in those who are monoinfected. This may also account for higher HCV transmission to children born to coinfected mothers. Therefore, assays with a wide dynamic range may represent an advantage. 1.1.3. Step 3: Use HCV genotype determination in predicting treatment response. Distribution of genotypes differs between HCV-monoinfected and coinfected patients, as illustrated in Table 1. 235 ManageMent of Hepatitis C and HiV CoinfeCtion Table 1. distribution of genotypes by monoinfection and coinfection, in % Genotype 1 Genotype 2 Genotype 3 Genotype 4 Monoinfected 65 12 19 3 Coinfected 60 5 28 8 Source: Fried et al., Tottiani et al. (33, 34). • Infections with more than one HCV genotype appear to be more often (>5%) in patients coin- fected with HCV and HIV, particularly IDUs and haemophiliacs (29, 35). • HCV genotype plays a predominant role as a predictor of SVR in HIV-infected patients, as it has been found in all studies of people without HIV infection. ° For genotypes other than 1 or 4, SVR rates are generally high, ranging from 73% in the ACTG 5071 study (4) to 62% in the APRICOT study (3), 53% in the Barcelona study (5) and 44% in the RIBAVIC study (2). ° For genotype 1, SVR rates range from 29% in APRICOT (3) to 17% in RIBAVIC (2) and 14% in ACTG 507 (4), while Barcelona reported a 38% SVR rate for those with genotype 1 or 4 (5). For more information about laboratory assays for HCV, please see Annex 1. 1.2. Evaluation of HCV disease severity • Evaluation of HCV disease severity should include attempting to define the duration of the in- fection. The date of infection is usually defined as the first date of risk exposure to HCV infec- tion (first drug injection date, etc.). • For decisions regarding treatment, the focus of the evaluation should be on chronic liver disease, comorbidities and co-conditions. 1.2.1. Clinical evaluation of liver disease Clinical signs of cirrhosis are: • stellar angiomas • dysmorphic liver • digital hippocratism (clubbing of the fingers) • collateral abdominal circulation • signs of hepatic decompensation (ascites, icterus, encephalopathy, etc.). 1.2.2. Biochemical parameters Biochemical tests to be performed are: • transaminases (ALT, AST)2, 3 • gamma glutamyl transpeptidase (GGT) (may increase in case of cirrhosis) • alcalines phosphatases (to establish another possible cause of hepatic disease) • bilirubine • albumin • prothrombin time. 2 Alanine aminotransferase (ALT) levels do not necessarily reflect the stage of fibrosis, especially in HCV/HIV-coinfected pa- tients. A normal ALT level alone should not be grounds to defer treatment. A biopsy in this situation can help to make a more informed decision. In the RIBAVIC study, baseline ALT >3 times the upper limit of normal was a predictor of higher SVR. 3 Asparate aminotransferase (AST) levels should be controlled when performing the initial complete hepatic evaluation to elimi- nate other causes of hepatic disease; for example, in cases of alcoholic intoxication there may be an increase in AST and GGT. 236 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 1.2.3. Child-Pugzh score The Child-Pugh Score, combining clinical symptoms and biological tests (Table 2), is useful for grading the severity of ESLD and should be performed in all patients with cirrhosis (36). Table 2.

Source: Pugh et al. (36). Interpretation of the Child-Pugh classification: • Class A (5–6 points) – compensated cirrhosis • Class B (7–9 points) – compensated cirrhosis • Class C (10–15 points) - decompensated cirrhosis 1.2.4. Ultrasound Ultrasound (Doppler if possible) examination of the liver can reveal: • cirrhosis: dysmorphy of the liver • steatosis: hyperechogenic liver • possibly early HCC: nodular unique or, rarely, multiple lesions. 1.2.5. Histological evaluation Liver biopsy is the standard procedure for evaluation of the severity of liver disease (see Table 3 for indications). It is especially important for patients with a suspected low chance of SVR (genotype 1 with a high viral load) or excess risk of severe side-effects, and allows evaluating: • the degree of fibrosis and necroinflammatory activity • the presence of comorbidities (steatosis, drug toxicity, alcohol related lesions, HBV). Table 3. indications for liver biopsy in HCV/HiV-coinfected patients Indications for biopsy Biopsy not required Genotype 1 or 4 with high HCV viral load (>800 000 IU/ml) Presence of comorbidities: - excessive alcohol consumption - coinfection with HBV and/or hepatitis delta virus - suspicion of medication-associated hepatotoxicity Genotype 2 and 3 Genotype 1 (and probably 4) with low HCV load (≤800 000 IU/ml) Clinical signs of cirrhosis Biopsies must be performed by trained physicians, as significant complications may occur in 1/200 patients. They should be read by specialized anatomopathologists, as subtle differences may change 237 ManageMent of Hepatitis C and HiV CoinfeCtion the classification of the severity of the disease. These limitations impede generalized biopsies for all HCV-infected patients (see section II.1.2.7 below for clinical situations not requiring liver biopsy). Activity and fibrosis are two major histological features of chronic hepatitis C that are included in proposed classifications, such as Ishak, Metavir and Knodell, that allow improved consistency in interpretation of hepatic fibrosis with a somewhat weaker reproducibility for hepatic inflammation grade (37, 38). See Table 4. Table 4. Metavir classification: activity and fibrosis scoring Activity score (A) Lobular necrosisAbsent (0) Moderate (1) Severe (2) Parcellar necrosis Absent (0) A0 A1 A2 Minimal (1) A1 A1 A2 Moderate (2) A2 A2 A3 Severe (3) A3 A3 A3 A0 = no histological activity; A1 = minimal activity; A2 = moderate activity; A3 = severe activity. Table 4a. Fibrosis score (F) F0: absence of portal fibrosis F1: stellar portal fibrosis with no septa F2: portal fibrosis with some septa F3: many septa but no cirrhosis F4: cirrhosis Source: Simmonds et al. (20). This system assesses histological lesions in chronic hepatitis C using two separate scores, one for necroinflammatory grade (A for Activity) and another for the stage of fibrosis (F). The fibrosis stage and inflammatory grade are correlated, but for approximately one third of patients there is discordance. In lower grades of liver fibrosis (F0–F1), regardless of HCV genotype, treatment can be deferred. See Table 4a. 1.2.6. Non-invasive markers of liver fibrosis Non-invasive tools for assessing liver fibrosis, such as those based on serum markers (for example, FibroTest™) or image technique (for example, FibroScan™) are available. Several non-invasive methods to evaluate inflammation and fibrosis have been developed for monoinfected patients and include serological tests combining serum fibrosis markers. They are used to distinguish Metavir fibrosis stages 0–2 from stages 3 and 4. The tests are quite reliable, are better accepted by patients than biopsies and could potentially save approximately 50% of patients from being biopsied. Recently, alternatives to biopsies have become available for coinfected patients (39), including a combination of biochemical tests indicating the degree of liver inflammation and fibrosis, such as the Forns index which has been recently validated for HIV/HCV-coinfected patients (40), and an elastometric method reflecting the degree of fibrosis (see Annex 2) (41, 42). 238 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 1.2.7. Clinical situations not requiring histological evaluation The First European Consensus Conference on the Treatment of Hepatitis in HIV-Infected Patients did not mandate biopsy in cases where treatment is already indicated (43). Treatment without bi- opsy or other liver assessment is recommended in the following situations: • infection with HCV genotype 2 or 3; • infection with HCV genotype 1 with a low viral load; and • absence of major contraindications and patient willingness to undergo treatment, in which case the SVR will be on the order of 40–60% (2–5). Given the limitations of biopsy and the faster progression of fibrosis in HCV/HIV patients, treat- ment should still be offered when candidates for biopsy decline it or lack access to it. 1.3. Evaluation of comorbidities and co-conditions 1.3.1. Psychiatric disorders • An initial evaluation of psychiatric disorders should be performed, as treatment with IFN can reveal and worsen depression. Treatment for hepatitis C should therefore be deferred in patients with moderate to severe depression until the condition improves. Prophylactic treatment with psychiatric drugs may be advisable and treatment may be feasible thereafter. • In patients with mild psychiatric illness, treatment for hepatitis C should not be deferred and counselling and/or antidepressant medication should be offered along with HCV treatment. 1.3.2. Alcohol abuse • Assessment of alcohol intake is an important part of evaluation (please see Annex 3). • Heavy alcohol intake (50 g/day or more) contributes to fibrosis of the liver, which can be identi- fied by biopsy in HCV patients independently of other predictors. This intake is equivalent to five or more drinks per day, in which a drink = 10 g of alcohol, for example 330 ml (12 oz) of beer, 150 ml (5 oz) of wine or 38 ml (1.25 oz) of hard alcohol. • There is evidence of synergistic interaction between alcohol consumption ≥80 ml/day and chronic HBV or HCV infection (44). Continued alcohol consumption increases HCV replica- tion, accelerates fibrogenesis and liver disease progression in hepatitis B and C and diminishes the response and adherence to treatment (especially if consumption is >50 g/day). • Active alcohol intake is considered a relative contraindication for IFN-based treatment, due to the documented non-compliance of heavy drinkers in medical therapies, combined with the side-effects that otherwise affect compliance (45). • Psychological, social and medical support should be offered to reduce alcohol intake to <10 g/day or stop it altogether. 1.3.3. Drug use • Treatment of patients on opioid substitution therapy should not be deferred. • Initiation of HCV treatment in active drug users should be considered on a case-by-case basis. (Please refer to Protocol 5, HIV/AIDS treatment and care for injecting drug users.) • Medical, psychological and social support from a multidisciplinary team should be provided for these patients. 239 ManageMent of Hepatitis C and HiV CoinfeCtion 1.3.4. Other comorbidities and co-conditions Testing of comorbidities should include a comprehensive history with a particular focus on factors associated with more progressive liver injury. Analysis can include: • testing for viral liver diseases4 • testing for tuberculosis (TB) and sexually transmitted infections (STIs) that need treatment be- fore HCV treatment begins.5 When a treatment has been decided, other tests are needed: • thyroid-stimulating hormone (TSH) dosage; • dosage of antiperoxydase, antinuclear, anti-smooth muscle, anti-liver-kidney microsome anti- body (LKM1); • creatininaemia; • proteinuria ; • glycaemia; • ferritinaemia; • electrocardiogram (ECG, to detect coronary disease that could decompensate after treatment- induced anaemia); • a pregnancy test.6 4 For HBV and HAV please refer to Protocol 7, Management of hepatitis B and HIV coinfection. 5 See Protocol 4, Management of tuberculosis and HIV coinfection, and the European STD Guidelines (46). 6 It should be explained that because RBV is teratogenic and contraindicated during pregnancy, procreation should be avoid- ed during treatment and six months after, and that due to higher levels of HCV viraemia in coinfected women, approximately 20% transmit HCV to their offspring, versus 7–8% in those monoinfected with hepatitis C (47). 240 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 1.4.

Liver biopsy is limited to patients with genotype 1, high viral load and low response to PEG-IFN and RBV. • Subsequent to an HCV/HIV positive serology, qualitative HCV RNA detection should be under- taken to confirm the chronicity of hepatitis. • In case of positive HCV RNA, a genotyping should be performed. • In case of genotype 2 or 3, more frequently found in IDUs, treatment should be proposed for all patients without liver biopsy where there is no contraindication (please see contraindications in section III.2.3). • In case of genotype 1, the patient should have a quantification of HCV RNA, since responses are related to viral load. This test should be available everywhere HIV viral load is performed. • In the absence of local testing possibilities, the patient should be referred to a specialist, or a sample should be collected at the district level and a genotyping test done centrally. ° When viral load is low (≤800 000 IU/ml), treatment of genotype 1 is recommended without a liver biopsy. ° When viral load is high (>800 000 IU/ml), an assessment of liver fibrosis by biopsy is rec- ommended to differentiate patients with severe liver disease. • A fibrosis score of F2–F4 indicates a need for immediate treatment. • Mild liver disease (F0, F1) indicates that treatment should be delayed due to the low chances of SVR. • Follow-up treatment should rely on HCV RNA quantification at week 12, and then HCV RNA qualitative detection at weeks 24 and 48. ° At week 12, if the drop of viral load is less than 2 log, the treatment should be stopped be- cause the chance of success does not exceed 1–2% regardless of genotype. Otherwise, the treatment should be continued. ° Additional qualitative tests should be performed at week 24 and treatment should be stopped if HCV viral load is detectable; otherwise, treatment should be pursued until week 48 and treatment efficacy checked with a qualitative test at this time. ° At week 72, HCV RNA detection should confirm or disprove a sustained virological re- sponse. • Patients with cirrhosis should also be referred to a specialist for initial evaluation of their cir- rhosis. 242 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 1.4.2.

Assessment of HIV risk and diagnosis of HIV/AIDS in HCV patients All patients with HCV should be offered HIV testing and counselling because the two viruses share transmission routes and because HIV exacerbates the development of HCV. Health-care providers should explain the reasons for offering the test to patients and its importance in proper clinical man- agement. However, patients have the right to opt out. Initial assessment of HIV status should include: • HIV pretest counselling; • serological testing (typically enzyme-linked immunosorbent assay (ELISA) and/or rapid tests) for HIV antibodies, followed by a western blot confirmatory test if positive; and • post-test counselling, including information on reducing risky behaviour, regardless of whether the HIV results were positive or negative. Further clinical evaluation of HIV-infected patients is required to develop a strategy of clinical management. It should include: • checking symptoms • a physical examination • evaluation of mental health and preparedness for treatment • a routine laboratory assessment • a CD4 lymphocyte count to determine the severity of immunodeficiency • viral load testing if available • pregnancy testing if indicated • testing for comorbidities, including hepatitis B, TB and psychiatric disorders • other tests as indicated by the patient’s condition.

Clinical management of HCV/HIV patients The key issue in the clinical management of HCV/HIV-coinfected patients is the treatment decision for each condition and when to initiate it. By the end of the laboratory and clinical assessment of patients with HCV/HIV coinfection, patients can be split into four categories: 1. patients not requiring hepatitis C or HIV/AIDS treatment 2. patients requiring only hepatitis C treatment 3. patients requiring only HIV/AIDS treatment 4. patients requiring both hepatitis C and HIV/AIDS treatment. 1. Coinfected patients not requiring any treatment Coinfected patients not requiring any treatment meet the following criteria: • CD4 count >350 cells/mm3 and absence of HIV-related symptoms, and • HCV antibodies, but absence of HCV RNA replication.7 • Coinfected patients not needing treatment should be monitored every six months (clinical fol- low-up, liver function tests) and every three years for histological liver lesions (using alterna- tives to liver biopsies). 2. Coinfected patients requiring only HCV treatment Coinfected patients requiring only HCV treatment meet the following conditions: • CD4 count >350 cells/mm3 and absence of HIV-related symptoms, and • active or chronic hepatitis C.8 HCV treatment offers the possibility of eradicating HCV within a defined treatment period. In the following situations, where the benefits outweigh the risks, there are two main reasons to consider all HCV/HIV-coinfected patients for HCV treatment: • The liver disease progresses more rapidly to end-stage complications and at earlier ages than in HCV-monoinfected patients. • Patients are at higher risk for developing hepatotoxicity following the initiation of ART than HIV-monoinfected patients. Efficient HCV treatment will hence facilitate the subsequent man- agement of ART. 2.1. Indications for HCV treatment • Genotype 2 or 3 regardless of HCV viral load or histology • Genotype 1, viral load ≤800 000 IU/ml regardless of histology • Genotype 1 or 4, viral load >800 000 IU/ml and moderate or severe fibrosis 2.2. Predictors of sustained virological response probability Several baseline parameters can predict a greater likelihood of achieving an SVR (32): • infection with genotype 2 or 3 • viral load ≤800 000 IU/ml • absence of cirrhosis • age <40 years • ALT levels >3 x upper limit of normal. 7 Some patients may have HCV RNA but harbour genotype 1 or 4 and a mild disease. In such cases, treatment is not recom- mended; regular yearly monitoring is the recommended option, with an assessment for liver fibrosis after three years. 8 For patients with evidence of advanced liver fibrosis, HCV treatment should be a priority. 245 ManageMent of Hepatitis C and HiV CoinfeCtion 2.3. Contraindications for hepatitis C treatment The following contraindications for treatment of hepatitis C should be borne in mind: • pregnancy, because of risk of IFN and RBV9,10 • cardiopathy, such as ischaemic disease and cardiac insufficiency • psychiatric disorders or history of same • active alcohol intake (>50 g/day) • decompensated cirrhosis (Child-Pugh C).11 2.4. Treatment of acute hepatitis C • Treatment of acute hepatitis C may reduce the risk of chronicity (51). Therefore, if serum HCV RNA is not eliminated spontaneously within three months of the disease onset (clinically and/or laboratory documented), treatment with PEG-IFN is recommended for six months (51). • The use of combination treatment in this population remains a field of research. 2.5. Treatment of chronic hepatitis C (doses and schedules) All patients should receive a combination of PEG-IFN α2a or α2b and RBV. The standard dose for PEG-IFN α2a is 180 µg once weekly (QW), and for PEG-IFN α2b it is 1.5 µg/kg body weight QW (2–5). The dose of RBV is critical. Although clinical trials in HIV/HCV-coinfected patients have used a fixed dose of 800 mg per day [400 mg twice daily (BID)] for all genotypes, studies from HCV- monoinfected patients support the use of 1000 mg to 1200 mg RBV per day (in 2 doses) for treat- ment of infections with genotypes 1 and 4, and 800 mg RBV per day (400 mg BID) for genotypes 2 and 3 (49). The current recommendations are as follows: • for HCV/HIV-coinfected patients with genotype 1 or 4, an initial RBV dose of 1000–1200 mg once daily (OD); • for HCV/HIV-coinfected patients with genotype 2 or 3, 800 mg OD (43). 9 Limited data suggest IFN does not have any effect on the embryo or foetus. 10 RBV is teratogenic (causes birth defects) in multiple animal species and its use during pregnancy is contraindicated (48). Since RBV may cause abnormalities in sperm, men taking it should wait six months after discontinuing use before attempting to impregnate a woman. 11 IFN is very badly tolerated in these patients (49); however, after regression of the decompensation, treatment may sometimes be initiated (50) and liver transplantation should be the primary treatment option for such patients. 246 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Fig. 8. therapeutic algorithm for HCV treatment in HiV-infected patients Source: Alberti et al., Sulkowski (43,52) 2.6. Treatment duration Regardless of genotype, the expected duration of treatment in coinfected patients should be 48 weeks. However, depending on HCV RNA levels at week 12, treatment may be interrupted earlier (refer to Algorithms 1 and 2 in section II.1.4 above) (43). Genotype 2 and 3 patients treated for six months have significantly higher relapse rates than those treated for one year (5, 53). Therefore, all HCV/HIV-coinfected patients should be treated for one year. HCV genotype can be used as a predictor of response but not as a basis for modifying treat- ment duration, as with immunocompetent patients. 3. Coinfected patients requiring only HIV/AIDS treatment Coinfected patients requiring only HIV/AIDS treatment satisfy at least one condition in each of the following bullet points • CD4 count ≤350 cells/mm3 in symptomatic patients or patients with viral load >100 000 copies/ml, or CD4 count ≤200 cells/mm3 irrespective of symptoms; and • HCV antibodies but no HCV RNA replication, or hepatitis C with contraindications to treatment (in the knowledge that they may be transient – see section III.2.3 on contraindictions). 3.1. Initiation of HAART Initiation of ART in HCV/HIV-coinfected patients should follow the current recommendations for HIV-monoinfected patients (54). (For further details, please refer to Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents.) (see Table 6) Genotype 2 or 3 Ribavirin 800 mg/day Low HCV RNA ≤800 000 IU/ml <5.9 log IU/ml High HCV RNA >800 000 IU/ml >5.9 log IU/ml Ribavirin 1000-1200 mg/day Regardless of genotype, add either: PEG-IFN α2a, 180 μg QW OR PEG-IFN α2b, 1.5 μg/kg body weight QW Genotype 1 or 4 Histology evaluation or non-invasive methods 247 ManageMent of Hepatitis C and HiV CoinfeCtion Table 6. Recommendations for initiating HaaRt in HCV/HiV-coinfected patients CD4 cell count Recommendations CD4 <200 cells/mm3 Antiretroviral treatment CD4 200–350 cells/ mm3 or VL > 100 000 copies/ml Antiretroviral treatment should be considered when there is a high viral load, a rapid decline in CD4 count or the presence of symptomatic HIV disease. It should be started before the CD4 count falls to <200 cells/mm3. 3.2. Considerations in choosing a HAART regimen In HCV/HIV-coinfected patients, the selection of an adequate first-line regimen should take into account major concerns and potential problems: • adherence (a once-daily regimen should be favoured); • hepatotoxicity of non-nucleoside reverse transcriptase inhibitors (NNRTIs) (acute, such as with nevirapine (NVP)); • drug interaction: didanosine (ddI) and zidovudine (ZDV) with RBV, efavirenz (EFV) and PEG- IFN (severe depression); • use of opioid substitution therapy (OST): pharmacokinetic interaction between NNRTIs and methadone or buprenorphine (dose adjustments); • coexistent medical/psychiatric conditions; and • the same concerns as in monoinfection: potency, maintenance of future options, cost and avail- ability. 3.3. First-line HAART regimens Table 7. treatment Regimens for first-line HaaRt in HCV/HiV-coinfected patients ARV drug classes HAART regimens Preferred first line 2 NRTIs + 1 NNRTI Alternative first line 3 NRTIs Ó Ï 3TC or FTCc Ï ¯ a ZDV is not an absolute contraindication if a patient is on RBV, but haemoglobin (Hb) levels should be closely monitored. b EFV has been considered the preferred NNRTI option, but NVP can be considered for patients without evidence of hepatic dysfunction, with close monitoring. However, it should be avoided in HIV-infected patients if CD4 is >400 cells/mm3 (>250 mm3 in women) (55). c Emtricitabine (FTC) is equivalent to 3TC. FTC is available together with TDF, and 3TC together with ABC as fixed-dose combination (FDCs). d ZDV/3TC/ABC regimen is available as an FDC. • In case of severe toxicity and side-effects in first-line antiretrivorals (ARVs), substituting another ARV with a different toxicity profile within the front-line regimens is recommended. • Switching to second-line ARV regimens is recommended in the absence of immunological or virological response to ART, as measured by CD4 cell count and viral load.

Second-line HAART regimens For second-line HAART, WHO recommends selecting three different drugs containing at least one new pharmacological class. • The best options are regimens with a boosted protease inhibitor (PI) as the key drug, together with two nucleosides if a classical approach of 2 NRTIs + 1 NNRTI was the first-line treat- ment. • In case of a simplified first choice with 3 NRTIs, the second-line should use a boosted PI + 1 NNRTI and/or 1 NRTI. Among second-line NRTIs, those with better resistant profiles, such as ddI, ABC and TDF, should be given preference. • The combination d4T+ddI has to be avoided due to the risk of mitochondrial toxity, leading to hepatic steatosis and potentially enhancing fibrosis (56). • TDF/ddi is also contraindicated due to negative pharmacological interactions.

It is contraindicated in patients with cirrhosis and under RBV treatment, and should be used with caution in patients with less severe liver disease. b Unboosted ATZ or NFV can be used in absence of a cold chain. 4. Coinfected patients requiring both HCV and HIV/AIDS treatment Coinfected patients requiring both HCV and HIV/AIDS treatment meet the following criteria: • CD4 count ≤350 cells/mm3 in symptomatic patients or patients with viral load >100 000 cop- ies/ml, or CD4 count ≤200 cells/mm3 irrespective of symptoms; and • acute or chronic hepatitis C.12 4.1. Strategy for initiation of treatment See Table 9 below. • If a coinfected patient has severe immunodeficiency (CD4 count <200 cells/mm3), the CD4 count should be improved using HAART before commencing HCV treatment. • If CD4 is between 200 and 350 cells/mm3, HCV treatment should be offered first in order to avoid interactions between HAART and anti-HCV drugs and facilitate adherence. After HCV treatment is finished (12 months), HAART should be initiated. • Patients, who need or are receiving HAART, should be in stable treatment (adherence to treat- ment, absence of side-effects, CD4 >200 cells/mm3) for a few months before starting HCV treatment. HAART should be continued during HCV treatment but ddI, ZDV or d4T should be changed for other drugs (ABC, TDF, etc.) before initiating RBV. 12 For patients with evidence of advanced liver fibrosis, HCV treatment should be a priority. 1 NNRTI +/- 1 NRTI + 1 boosted PI or double PI 249 ManageMent of Hepatitis C and HiV CoinfeCtion • In some cases (if CD4 nadir has never been <200 cells/mm3), interruption of HAART during HCV treatment is feasible if the patient asks for it. In this case, the original regimen is usually reintroduced after the end of HCV treatment or in case the CD4 count drops <200 cells/mm3 during the treatment. • Patients with a low baseline CD4 count (<200 cells/mm3) may tolerate HCV treatment less well and may be at higher risk for developing opportunistic infections, since IFN treatment is often associated with loss of CD4 cells in the bloodstream, although the CD4 percentage is conserved (2–5). Table 9. algorithm for initiation of hepatitis C treatment and HaaRt in HCV/HiV-coinfected patients Patients HAART HCV treatment Untreated No indication for ARV CD4 >350 cells/mm3 Treat HCV first ARV initiation indicated CD4 200–350 cells/mm3 Treat HCV first, then initiate HAART CD4 <200 cells/mm3 Initiate HAART, wait until stable, and regimen is well tolerated, then treat HCV ARV-treated Replace ddI and ZDV if on alternative options. It is possible to interrupt HAART until the end of HCV treatment (if CD4 nadir was never <200 cells/mm3, and patient asks for it). Treat HCV if CD4 > 200 cells/mm3. 4.2. Considerations of ARVs when treating both HCV and HIV infections 4.2.1 Zidovudine (ZDV) ZDV, when taken concomitantly with RBV, is associated with an increased frequency of anaemia, but not severe neutropenia. When alternative options are available, ZDV should be replaced by another NRTI during HCV treatment. 4.2.2 Didanosine (ddI) Didanosine used in association with RBV was shown to be associated with a markedly increased risk of lactic acidosis, pancreatitis (57, 58) and an unexpected number of hepatic decompensa- tions in patients with cirrhosis (59). It is consequently contraindicated in patients with cirrhosis and should be used with caution in patients with less severe liver disease during PEG-IFN + RBV combination treatment. 4.2.3 Efavirenz (EFV) EFV and PEG-IFN can be co-prescribed but must not be initiated simultaneously, as both drugs can induce psychiatric troubles. If EFV is well tolerated then IFN can be added. 4.2.4 Protease inhibitors (PIs) A potential negative impact of PI use on SVR in patients with HCV/HIV coinfection treated with PEG-IFN + RBV has been suggested in a subgroup analysis of a single study (25). As there is no solid evidence regarding this possible negative impact of PI use on SVR, PIs cannot be excluded from recommended ARVs for HCV/HIV patients. However, more research is needed to obtain better evidence. 250 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 4.3. Hepatotoxicity of ARV drugs HAART is associated with a higher risk of hepatotoxicity (defined as at least two fold ALT/AST increase above upper limit of normal (ULN)) in HCV/HIV-coinfected patients than in HIV-monoin- fected patients (30, 60–64). However, the incidence and risk factors for liver enzyme elevations in large cohorts of HCV/HIV-coinfected patients are not well defined. In several studies, however, independent risk factors for hepatotoxicity have been identified (30, 60–64): • previous liver transaminase elevations to a grade ≥ III • higher baseline alanine amino-transferase values • viral coinfection • high plasma drug levels • degree of immune damage (64). Hepatotoxicity has been associated with all currently used ARV drugs, but existing studies fail to demonstrate a consistent association between particular drugs or drug classes and the development of subsequent hepatotoxicity. Comparison of HAART regimens (single-PI, multiple-PI and NNRTI- based) has given inconsistent results for liver-tolerability in cohorts in which HCV/HIV-coinfected patients are underrepresented. • Acute hepatotoxicity: in a single cohort study involving HCV positive and negative patients, the use of NVF within 12 weeks of initiating treatment and the use of full-dose ritonavir (RTV) (600 mg BID) have been implicated (62). But most liver enzyme elevation events are sub-clinical and usually reverse spontaneously. NVP is not contraindicated in all HCV/HIV-coinfected subjects, but should be closely monitored when used in asymptomatic patients. A majority of experts recommend avoiding its use in patients with evidence of liver dysfunction. • Chronic hepatotoxicity: the prolonged use of nucleoside analogue reverse transcriptase inhibi- tors (especially of those having a strong affinity for mitochondrial deoxyribonucleic acid (DNA) polymerase, such as ddI and d4T) exposes treated patients to a risk of chronic mitochondrial toxicity, whose target, among other organs, is the liver. This toxicity, possibly exacerbated in some patients by the specific chronic toxicity of PIs on the liver, may lead to hepatic steatosis and worsen pre-existing fibrosis. 4.4. ARV dose adjustment in patients with cirrhosis • Like a majority of drugs metabolized in the liver, antiretroviral agents such as PIs and NNRTIs are metabolized with difficulty in patients with cirrhosis (65, 66). • Although the relationship between high plasma concentrations and toxicity is not constant for all antiretroviral agents, it has been clearly demonstrated for certain PIs, such as NFV, LPV and amprenavir (APV), and NNRTIs such as EFV (67–70). • Of the NRTIs, only ZDV and ABC are metabolized by liver enzymes other than cytochrome P450 (CYP) (65, 66). Consequently, use of PIs, NNRTIs, ZDV or ABC in patients with liver- decompensated cirrhosis requires dosage adjustment in order to avoid a risk of drug accumula- tion. However, little specific guidance has been established to precisely adapt ARV dosages in patients with cirrhosis. 251 ManageMent of Hepatitis C and HiV CoinfeCtion Table 10.

Clinical monitoring HCV/HIV coinfected patients should be carefully monitored during treatment. For monitoring of patients receiving ART please refer to Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents. Patients treated for HCV should be followed monthly for clinical evaluation of treatment tolerance. The tests to be regularly performed are shown in Table 11. Table 11.

Virological response monitoring See Table 11 above. The virological response should be monitored by serum HCV RNA quantification before initiation of treatment and 12 weeks after starting treatment using the same sensitive test with a lower detec- tion limit of 50 IU/ml: • For patients with at least a 2 log reduction in viral load at week 12 – defined as an early virologi- cal response (EVR) – treatment should be continued. • If a 2 log reduction in viral load is not achieved at week 12, treatment should be stopped, be- cause the negative predictive value of achieving SVR is 99–100%. This rule is applicable to all genotypes. The log rule at week 12 in coinfected patients is of great relevance to optimizing treatment. It encourages treatment of all candidates in the absence of contraindication, given that treatment can be stopped after 12 weeks if there is no chance of a cure. After week 12, assessment should be made by a qualitative HCV RNA test, as follows: • Week 24: for patients remaining positive for serum HCV RNA at week 24 (negative predictive value for achieving SVR is 100%), treatment should be discontinued. • Week 48 marks the end of treatment response. • Week 72: after six months off treatment, negative HCV RNA indicates an SVR. Recurrence of HCV infection thereafter is very rare. • A new assessment might also be useful 12–24 months after the end of treatment. 5.2. Histological response monitoring A new liver biopsy is not indicated except in patients with no SVR, for whom the result of liver biopsy could modify HCV treatment. 253 ManageMent of Hepatitis C and HiV CoinfeCtion 5.3. Tolerance monitoring See Table 11 above. A full blood count as well as transaminases and bilirubin tests should be performed in weeks 1, 2 and 4, and thereafter on a monthly basis. CD4 cell count should be monitored monthly. Additional laboratory tests can then be carried out at the physician’s discretion and should include assessment of thyroid-stimulating hormone (TSH) at least every three months. 5.4. Management of toxicity and side-effects of PEG-IFN + RBV treatment Side-effects of PEG-IFN and RBV occur in a majority of patients and may be severe (2–5, 71). Effort should be made to keep patients on the optimal dose of PEG-IFN plus RBV and to proac- tively manage side-effects of treatment. It is important to maintain the optimal doses of RBV and PEG-IFN during treatment, especially during the first 12 weeks. The use of erytropoetin may make it possible to avoid decreasing RBV dosage (72). However, if severe side-effects or laboratory ab- normalities develop during treatment and no growth factor is available, the dosages of each product have to be modified until the reactions disappear, as described in section 5.4.2 below. 5.4.1. Anaemia and neutropenia • Anaemia (<10 g/dl) is reported in up to 30% of patients receiving PEG-IFN + RBV and has been shown to impair quality of life (2–5, 71). • Anaemia increases with the concomitant use of ZDV and a lower baseline haemoglobin. • ZDV should be replaced in patients with ART alternatives. • Neutropenia (<1000 cells/mm3) is observed in up to 50% of patients, but serious bacterial infec- tions seem infrequent (2–5, 71). 5.4.2. Dose adjustment of PEG-IFN and RBV Table 12. dose adjustment for side-effects and toxicity Reduce RBV to 600 mg Withhold RBV Reduce PEG- IFN by 70%, 50%, 25% Withhold PEG-IFN Discontinue combination Absolute neutrophil count <750/mm3 <500/mm3 Platelet count 25 000– 50 000/mm3 <25 000/mm3 Haemoglobin - no cardiac disease - stable cardiac disease 8.5–10.0 g/dl decrease of ≥2 g/dl during any four weeks <8.5 g/dl <12 g/dl despite four weeks at reduced dose Source: European Medicine Agency (73, 74). • RBV should be reduced to 600 mg/daily (200 mg in the morning and 400 mg in the evening) if either of the following applies: ° the haemoglobin of a patient without significant cardiovascular disease falls to <10 g/dl and ≥8.5 g/dl; or ° the haemoglobin of a patient with stable cardiovascular disease fall by ≥2 g/dl during any four weeks of treatment (a return to the original dosage is not recommended). • RBV should be discontinued if either of the following applies. ° The haemoglobin of a patient without significant cardiovascular disease falls to <8.5 g/dl. ° A patient with stable cardiovascular disease maintains a haemoglobin value <12 g/dl despite four weeks on a reduced dose. 254 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION If the abnormality is reversed, RBV may be restarted at 600 mg daily, and be increased to 800 mg daily at the discretion of the treating physician (a return to the original dosage is not recom- mended). • In case of RBV intolerance, PEG-IFN monotreatment should be continued. • Dose reduction of PEG-IFN is recommended if the neutrophil count is <750/mm3 as described in Table 12 (53). For patients with an absolute neutrophil count <500/mm3 treatment should be suspended until values return to >1000/mm3. Treatment should be reinstituted at 50% of the dose and the neutrophil count monitored. • A 50% dose reduction is recommended if the platelet count is <50 000/mm3. Cessation of treat- ment is recommended when platelet count decreases to levels <25 000/mm3. 5.4.3. Influenza-like symptoms • Paracetamol (possibly combined with non-steroidal anti-inflammatory drugs) should be used for influenza-like syndrome, particularly before injection of PEG-IFN. • Low platelets are a relative contraindication for the use of acetylsalicylic acid, diclofenac or ibuprofen, because of the inhibition of platelet aggregation. • Dose adjustment may be required in case of severe side-effects despite symptomatic treatment. An initial dose reduction to 75% or 50% of the dose is generally adequate. 5.4.4. Nausea Nausea can be reduced with metoclopramide 10 mg three times daily (TID). 5.4.5. Depression • Depressive mood changes are frequent and should be managed proactively with symptomatic treatment. In patients with a history of neurotic or minor depression, initiation of treatment with antidepressants before starting IFN-based treatment should be considered. Antidepressants are frequently needed for clinically-relevant depression. Use the following dosages: ° selective serotonin reuptake inhibitors such as citaprolamin, paroxetin and tricyclic at initial dosages of 20 mg/day; and ° antidepressants such as doxepine at an initial dosage of 50 mg/day. • Consultation with an experienced psychiatrist for the establishment of a standardized treatment procedure is recommended. • In patients with pre-existing depressive mood disorders or other profound neurotic disorders, initiation of specific psychiatric medication is recommended to reduce the destabilizing effect of IFN-based treatment. • In patients with a history of hospitalization due to major depression or psychosis, IFN-based treatment is generally contraindicated. In large controlled studies the incidence of attempted or completed suicides, psychosis and major depression is <1% (2–5, 71). The choice of treatment strategy should be made in consultation with a psychiatrist. • In patients with a history of injecting drug use, benzodiazepines should be avoided because of their potential to induce addiction. 5.4.6. Dysthyroidism IFN-induced dysthyroidism occurs in 7% of patients, but does not require treatment interruption. • Thyroid hormone substitution is used in case of hypothyroidism. • Beta-blockers are useful to relieve symptoms of hyperthyroidism (75). 5.5. Management of treatment adherence Even among patients who are appropriate candidates for treatment with IFN, acceptance of treat- ment is low in HCV/HIV-coinfected populations, predominantly due to treatment side-effects and toxicity. However, a proportion of patients who initially decline IFN treatment accept it after edu- cation and peer support programmes to facilitate successful treatment. Patients may continue to 255 ManageMent of Hepatitis C and HiV CoinfeCtion work if necessary, with possible working time adjustments to accommodate for treatment and drug reactions. Counselling is essential to increasing adherence. Physicians should: • listen to patients’ complaints • teach them to recognize and manage side-effects • discuss ways to improve compliance. A team approach to patient care and management is an effective strategy for increasing adherence. The team should include physicians, nurses, psychiatrists where relevant and social workers or other care providers. Initiatives that have proven effective include directly observed treatment, patient discussion groups, patient manuals, hotlines and psychological support. For further information on adherence please refer to Protocol 5, HIV/AIDS treatment and care for injecting drug users, and Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents. 5.6. Management of non-responders Non-response can be observed in any HCV treatment, ranging from “no viral decline during treat- ment” to “end-of-treatment virological response and subsequent virological relapse”. The decision to treat patients again with PEG-IFN plus RBV should be based on: • type of response • toleration of the previous treatment • extent of liver damage • HCV genotype. If the therapeutic aim in treating patients with biopsy-proven advanced fibrosis/cirrhosis is to delay or prevent disease progression in non-responders at week 12 and/or week 24, continuation with PEG-IFN monotreatment can be considered, since a histological response was observed in about 35% of non-responders who received PEG-IFN + RBV in four pivotal trials (2–5). However, data on dose, duration and clinical benefits of such maintenance treatment are very scarce in HCV/HIV- coinfected patients, and further research is needed. 5.7. Management of end-stage liver disease (ESLD)13 5.7.1. Testing for hepatocellular carcinoma (HCC) Cirrhotic patients should be screened for HCC at four-to-six-month intervals using ultrasonography and measurement of alfa-fetoprotein levels (43). It has been found that HCC occurs more rapidly and is more aggressive in patients with HIV infection (76). Patients whose test results are abnormal should be followed up at referral centres for diagnosis, staging and treatment, which is only avail- able for early-stage HCC (77). 5.7.2. Testing for oesophageal varices Annual endoscopy, including the investigation of oesophageal varices in the gastric fundus, is rec- ommended (43). In the presence of significant oesophageal varices, a prevention of bleeding by non-cardioselective beta-blockers (associated with variceal ligation in case of > grade 2 varices) is recommended (78). The most frequently prescribed drug is propanolol at a dosage varying from 40 to 160 mg/day in order to obtain a blocking effect (cardiac pulse reduction of 30%). 13 For further details on ESLD, please see Annex 4. 256 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 5.8. Drug–drug interactions 5.8.1. Interactions between HIV drugs and HCV drugs Interactions of ARV agents and anti-HCV drugs must be taken into account, as they partially ex- plain the high rate of side-effects in HCV/HIV-coinfected patients treated for HCV. • RBV competes for phosphorylation with thymidine and cytosine analogues such as ZDV and d4T (79, 80). However, in controlled trials, no effect of RBV on the efficacy of the ARV com- bination treatment has been observed (81). • IFN has a moderate antiretroviral effect which may compensate for the effect of RBV on the efficacy of the ART regimen (82). • In contrast, the phosphorylation of ddI is increased by RBV (83–87), which may explain some side-effects observed in co-administration (56–58). 5.8.2. Interactions among recreational drugs, OST, anti-HCV drugs and ARVs • No finding of interaction between opioids and anti-HCV drugs has been published. • All PIs and NNRTIs are substrates and potent inhibitors or inducers of the cytochrome P450 sys- tem. Many classes of recreational drugs, including benzodiazepines, amphetamines and opioids, are also metabolized by the liver and can potentially interact with antiretrovirals. Overdoses as a secondary reaction to interactions between the amphetamine-type stimulants (MDMA) and PIs, particularly RTV, have been reported. • ARVs that are CYP3A4 inducers (NVP, EFV and PIs) can decrease the level of methadone, causing withdrawal symptoms and increasing the risk of relapse into heroin abuse. • An opiate metabolism can be inhibited or induced by concomitant PIs, so patients should be monitored for signs of toxicity. Withdrawal symptoms generally occur within 4–10 days of ART initiation. Withdrawals should be monitored clinically and dose increases of 10 mg increments from days 8–10 should manage the problem. 5.9. Hepatotoxicity of TB drugs in chronic HCV infection • The rate of hepatotoxicity is significantly higher in TB patients with HCV or HBV coinfection (59%) than without coinfection (24%) (88). • Commonly used anti-TB drugs, such as isoniazid, rifampicin, pyrazinamide and ethambutol, are all hepatotoxic. • Pyrazinamide is the most hepatotoxic and should be avoided in TB patients with severe chronic liver disease (89). • It is not necessary to adapt doses of anti-TB drugs in hepatic insufficiency. • In decompensated liver disease, a regimen without pyrazinamide should be used. • Streptomycin, ethambutol, and a reserve drug such as fluoroquinolone can be used if treatment is necessary in patients with fulminant liver disease. Consultation by a specialist is required. • Alternative anti-TB drugs with lower hepatotoxicity (rifabutin, amikacin, ofloxacin, levofloxa- cin, etc.) might be used in cases of severe liver dysfunction, The treatment of these special cases should be decided in consultation with an acknowledged expert. • Hepatotoxicity occurrence justifies a monthly monitoring of liver functions. 257 ManageMent of Hepatitis C and HiV CoinfeCtion IV. Suggested minimum data to be collected at the clinical level The suggested minimum data to be collected is important in the development of key indicators on access to treatment and its success. Such indicators assist managers in decision-making on ways to strengthen and expand these services to all those in need. The following data should be collected at each clinical facility on a regular basis (e.g. monthly, quarterly or semi-annually): • number of HIV patients (“seen for care” – this will be the denominator for the data below); • number of HIV patients coinfected with HCV; • number of HCV/HIV-coinfected patients with chronic hepatitis C; • number of HCV/HIV-coinfected patients with chronic hepatitis C receiving: ° only HCV treatment ° only ART ° both treatments; and • number of HCV/HIV-coinfected patients who have died (in a given period) including cause of death (e.g. liver-related deaths, HIV/AIDS related mortality or non-HIV/AIDS related mortality such as accident, overdose or suicide). 258 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Annex 1. Laboratory assays for HCV (31) Detection of HCV antibodies Detection of HCV antibodies is the first step in screening patients for suspected HCV infection. Cur- rently available assays are highly sensitive, and specific HCV antibodies are detected with enzyme im- munoassays (EIA). These assays detect mixtures of antibodies directed against various HCV epitopes located in HCV proteins: core, NS3, NS4 and, in third-generation tests, NS5 (1, 6). The specificity and sensitivity of currently available EIAs for HCV antibodies are greater than 99% in immunocompetent patients with active viral replication (presence of HCV RNA). For patients with acute HCV infection, it is important to bear in mind that antibodies may not be detectable for three to eight weeks following initial infection. The presence of HCV antibodies is indicative of past or present infection. Antibodies persist indefinitely in chronically infected patients, but antibody titres may decrease or even disappear in patients who clear HCV either spontaneously or after ART. Different types of assays and immunoblot tests, were used in the past to confirm positive EIAs results in low-risk populations, such as in healthy blood donors. The excellent performance of currently avail- able EIAs and the general availability of HCV RNA testing make these assays outdated. In blood banks, nucleic acid testing (NAT) has recently been implemented. With NAT, the presence of HCV RNA is analyzed in small blood pools and, if a viral genome is detected, an individual analysis of the implicated blood samples is performed. With the addition of NAT, the risk of HCV transmission has been reduced to around 1/1 000 000 donations. Qualitative detection of HCV RNA HCV RNA can be detected as soon as a few days after infection. In general, qualitative assays to detect HCV RNA are more sensitive than most currently available quantitative assays. However, the latest quantitative methods are very sensitive and in the future could become the universally used methods. The qualitative detection procedure begins with RNA extraction from clinical samples. In most centres RNA extraction has become fully automated, increasing its reproducibility. Thereafter, the target is am- plified, either by PCR or TMA. There are currently two commercially available qualitative assays to detect HCV RNA: one PCR-based assay (Cobas Amplicor HCV v. 2.0, Roche) with a sensitivity of 50 IU/ml and one TMA assay (Versant HCV RNA qualitative assay, Bayer) with a sensitivity of 5–10 IU/ml. The specificity of both assays is close to 100%. Quantification of HCV RNA In individuals who become chronically infected, HCV RNA levels are relatively stable over time (90). HCV RNA quantification can be obtained by two techniques. 1. PCR assays Quantification is based on amplification of the viral template with a known amount of synthetic RNA standard added to each reaction. The relative amounts of amplified viral template and standard ampli- cons are measured at the end of the PCR reaction. More recently, “real time” PCR has been developed, with many advantages such as simplicity, rapidity, wider linear range of HCV RNA concentrations and minor risk of contamination. Real-time PCR is already replacing conventional PCR assays. 2. DNA assay Another approach to quantifying HCV RNA is signal amplification, in which viral genomes are released from the virions and hybridized in solution using target probes. The HCV RNA with target probes are 259 ManageMent of Hepatitis C and HiV CoinfeCtion then captured onto microwell plates. Additional target probes bind the viral RNA to branched-DNA amplifier molecules. The signal is amplified by hybridization of oligonucleotide probes conjugated with alkaline phosphatase for detection and quantification of the HCV RNA. Determination of HCV genotype (91) Two methods can be used to determine HCV genotype: 1. RT-PCR assay, based on analysis of the 5’ untranslated region of the HCV genome is the most com- monly used method. Typing errors are rare but can occur between genotype 1 and some isolates of geno- type 4; sub-typing errors might occur in 15–20% of cases. These errors can be explained by the high degree of nucleotide conservation within this region. 2. Serology: determination of HCV genotype can also be performed by detecting type-specific anti- bodies. Several antigenic determinants have been identified after epitope mapping of the NS4 and core proteins of HCV. These epitopes have been used to develop a competitive EIA (Murex HCV EIA) and an immunoblot assay (RIBA, Chiron Corp). There are studies demonstrating a lower performance of tests aimed at detecting HCV antibodies in HIV-infected patients, as well as cases of HCV antibody seroconversion coinciding with the administra- tion of HAART (probably due to immune restoration). However, latest generation HCV antibody EIAs have incorporated multiple HCV antigens and are very sensitive in HIV-infected patients. Recently, sera from 559 HIV-infected and 944 HIV-negative IDUs were tested both for HCV antibodies using a third-generation assay and for HCV RNA using a commercially available test. Of the HIV-infected indi- viduals, 547 (97.8%) had detectable HCV antibodies, and only one HCV antibody-negative patient had detectable HCV RNA (27, 28). The figure was similar for HIV-negative patients, indicating that HCV antibody screening using latest generation assays is reliable in coinfected patients. 260 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Annex 2.

Alcohol screening questionnaires The following is an overview of the most used and well-established alcohol screening questionnaires. CAGE Test CAGE (100) is an acronym of the four questions: 1. Have you ever felt you ought to Cut down on your drinking? (yes/no) 2. Have people Annoyed you by criticizing your drinking? (yes/no) 3. Have you ever felt bad or Guilty about your drinking? (yes/no) 4. Have you ever had a drink first thing in the morning to steady your nerves or get rid of a hangover (Eye- opener)? (yes/no) Item responses are scored 0 or 1, with a higher score an indication of alcohol problems. A total score of 2 or greater is considered clinically significant. AUDIT Test The AUDIT Test (101) was developed as a simple method of screening for excessive drinking, alcohol de- pendence and harmful drinking (see Table 14 below). It has the following advantages: • cross-national standardization, the only screening test designed for international use; • identifies hazardous and harmful alcohol use, as well as possible dependence; • it is brief, rapid and flexible; • designed for primary health-care workers; and • focuses on recent alcohol use. A score of 8 in men and 7 in women indicates a strong likelihood of hazardous or harmful alcohol consump- tion. A score of 13 or more is suggestive of alcohol-related harm. 262 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Table 14. aUdit test 1.

Management of end-stage liver disease Hepatocellular carcinoma As HIV-infected patients live longer, especially in industrialized countries where they have access to HAART, HCC may begin to emerge in those who would have otherwise have succumbed to compli- cations from their primary HIV disease. For this reason, HCC is projected to become an increasingly significant clinical problem in the HIV populations (76, 102–104). Early diagnosis of HCC is particularly important in patients coinfected with HCV and HIV, because it is more aggressive and, in its advanced stages, incurable (59). Prevention, therefore, becomes key to controlling the health-care burden of this disease. The recommendations for HCC management developed in 2000 by the European Association for the Study of the Liver (EASL) (105) are being updated. Such recommendations might be problematic in view of the wide geographical variations in disease epidemiology and treatment availability. Guidelines for managing HCC arising in connection with HIV coinfection are lacking. Early diagnosis The 2000 EASL guidelines describe patient selection and surveillance intervals (105). Patients with cir- rhosis should be screened, if liver transplantation is feasible. A screening interval of every six months has been established to allow detection of tumours <3 cm in diameter. Patients whose screening results are abnormal should be followed up at referral centres for diagnosis and staging. Ultrasonography and measurement of alpha-fetoprotein (AFP) levels, at six-month intervals, are the most commonly used methods to screen patients with cirrhosis for HCC (77, 106). AFP values >400 ng/ml are considered diagnostic of HCC. Treatment Treatment for HCC is usually classified as curative or palliative (77, 105). Curative treatment includes: • surgical resection • liver transplantation • arterial embolization • percutaneous ethanol injection in patients with small tumours who are not candidates for resec- tion; a modest survival advantage has been shown for chemoembolization in randomized, con- trolled trials and one meta-analysis. Most patients cannot undergo resection or liver transplantation because of underlying cirrhosis or advanced disease at diagnosis. Early-stage HCC A solitary tumour <5 cm, or up to 3 tumours <3 cm, in a patient with well-preserved liver function, constitutes early-stage HCC (4, 8). Monoinfected patients can be successfully treated with curative therapies, although response rates and survival benefits are variable. Surgical resection and trans- plantation yield 5-year survival rates ranging from 60% to 70%. Recurrence, however, can be as high as 50% at 3 years and 70% at 5 years. Percutaneous ethanol injection induces a complete response in about 80% of patients whose tumours are ≤3 cm. Response rates are lower with large or multinodal tumours (105). 264 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Advanced HCC Most patients with HCC (approximately 50%) have advanced disease at diagnosis (77, 105). Pa- tients with advanced disease are candidates for loco-regional or systemic treatments rather than curative approaches (4). Transarterial chemoembolization is the only palliative therapy that has been shown to improve survival, with careful patient selection. Prevention and recurrence HIV patients are likely to have other risk factors predisposing them to HCC, such as alcohol abuse and concurrent HBV infection. Among HIV patients, vaccination against HBV is strongly recom- mended. HCV/HIV-coinfected patients should receive treatment for chronic HCV infection using combination IFN and RBV. Orthotopic liver transplantation Orthotopic liver transplantation (OLT), where available, is the only therapeutic option for patients with end-stage liver disease. Accumulated experience in North America and Europe in the last five years indicates that three-year survival in selected HIV-infected recipients of liver transplants was similar to that of HIV-negative recipients (107–110). HIV infection by itself is not, therefore, a con- traindication for liver transplantation. As the survival of HIV-infected patients with ESLD is shorter than that of non-HIV-infected pa- tients, the OLT evaluation should be done after the first liver decompensation. The current selection criteria for HIV-positive transplant candidates include: • no history of opportunistic infections or HIV-related neoplasms, except infections that can be efficaciously treated and prevented, such as TB, candidiasis or Pneumocystis jirovecii pneumo- nia (PCP); • CD4 cell count >100 cells/mm3; and • plasma HIV viral load suppressible with antiretroviral treatment. For drug users, a two-year abstinence from heroin and cocaine is also required, although patients in a methadone programme can be accepted. The main problems in the post-transplant period are pharmacokinetic and pharmacodynamic in- teractions between ARVs and immunosuppressors, and the management of HCV infection relapse, one of the main causes of post-transplant mortality. Experience with PEG-IFN and RBV is scarce in this population.

Research needs and alternative treatments Epidemiology Studies on the epidemiology and the social impact of HCV in patients infected with HIV should be actively investigated, with a special emphasis on vulnerable populations. HIV management Studies addressing the optimal time in the course of chronic HIV infection to commence ART in HCV-coinfected patients should be initiated. HCV management and physiopathology • Studies to validate the utility of non-invasive methods of liver disease progression should be performed. • Long-term follow-up studies of patients with and without SVR are strongly encouraged to deter- mine late relapses, the duration of histological improvement and the effect of clinically relevant outcomes such as decompensation, HCC and death. • Studies on pathophysiology, including extrahepatic viral reservoirs and the specific immune response to HCV, should be conducted. Future directions for treatment Research should also investigate: • optimizing the response to existing treatments, such as higher doses of RBV or PEG-IFN • treatment durations • the utility of maintenance treatment • the optimal regimen for delaying disease progression. Higher doses of RBV The optimal RBV dose for treatment of HCV genotype 1 and the potential benefits of prolonged treatment should be investigated. The optimal dose of RBV remains unclear. It is possible that higher SVR rates can be achieved by higher doses of RBV. In most of the published literature on HIV/HCV-coinfected patients, the RBV dose was 800 mg, in order to avoid anaemia, which was considered a greater problem in HIV-infected patients, especially those taking ZDV. However, in HIV-negative patients with genotype 1 HCV infection, it is clear that higher SVR rates are achieved with 1.0/1.2 g RBV (≤75 kg/>75 kg) than with 800 mg (49). Thus, alternative strategies for HIV- infected patients need also to consider higher RBV doses. It is important to note that higher RBV doses appeared to be well tolerated in the Barcelona study (5), where RBV was given by body weight as follows (per day): 800 mg, <60 kg; 1 g, 60–75 kg; and 1.2 g, >75 kg. Higher doses of IFN It is possible that higher SVR rates can be achieved by higher doses of IFN but this has not been investigated in HIV-infected patients. Treatment duration A shorter duration of treatment for patients with HCV genotypes 2 and 3 should be investigated. In HIV-negative patients, SVR rates are the same for genotype 2 and 3 HCV infections if they are treated for 24 weeks instead of 48. However, analogous studies have not been reported for PLHIV (5). Thus, studies emphasizing alternative dosing intervals are also needed for genotype 2 and 3 HCV infection before shorter regimens can be recommended. On the other hand, it might be useful to evaluate the usefulness of longer treatment duration for genotype 1 HCV infections with high viral loads. 266 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION IFN maintenance treatment Studies on the use of maintenance treatment in patients with no SVR and with advanced liver disease are strongly recommended, including evaluation of the optimal dose and duration of treatment. Maintenance treatment is aimed at decreasing the incidence of ESLD without effecting SVR. The histologic response results of the ACTG 5071 study (4) described above provide a rationale for this approach. There are studies designed to test this hypothesis in both HIV-infected (SLAM-C) and HIV-uninfected people (HALT-C), but it remains undecided. Acute HCV infection The optimal treatment for acute HCV infection in HIV-infected patients should be investigated. New treatments As the current therapies are suboptimal in efficacy, tolerability and quality of life, the development of new drugs to improve these issues should be actively pursued. Phase II and III trials of new drugs should be performed in HIV/HCV-coinfected patients as a prior- ity due to the accelerated course of hepatitis infections in these populations. There are many compounds under development, and some have progressed into Phase II clinical studies (111): • Viramidine (Valeant) is a prodrug of RBV that causes substantially less anaemia. In phase II studies, it was associated with less anaemia than RBV and SVR rates that were not inferior. Phase III studies are underway. • Albuferon-alfa™ (Human Genome Sciences), is a fusion of albumin and IFN that prolongs IFN half-life. • Interleukine-2 (IL-2) treatment has also been examined as a method to boost HCV antibody im- mune responses and enhance treatment responses. However, an early study in HIV/HCV-coin- fected patients was associated with significant toxicity and provided no evidence of effective- ness (10). • NM283 (Idenix) interferes with the HCV polymerase and, in Phase II studies; its use was associ- ated with a modest reduction in HCV RNA levels. • VX 950 (Vertex) is an HCV protease inhibitor that is being examined in clinical trials. The development of direct antivirals that block essential viral enzymes represents a straightfor- ward approach to developing new agents to target HCV. Although all HCV enzymes are, in theory, equally appropriate for therapeutic intervention, the NS3–4A serine protease and the NS5B RNA polymerase have emerged as the most popular targets. A number of competitive inhibitors of the NS3 protease as well as nucleoside and non-nucleoside inhibitors of the NS5B polymerase are be- ing developed. The efficacy shown by NS3 serine protease and the NS5B RNA-dependent RNA polymerase inhibitors in recent proof-of-concept clinical trials has validated the effort of finding clinical candidates and triggered a renewed interest in this area (112). 267 ManageMent of Hepatitis C and HiV CoinfeCtion Table 16. a sample of the drug pipeline for hepatitis C Compound Company Clinical phase Target Mechanism of action BILN 2061 (Ciluprevir) Boehringer-Ingelheim Phase IIa NS3–4A protease Product-derived serine prote- ase inhibitor VX-950 Vertex/Mitsubishi Phase Ib NS3–4A protease Serine protease reversible covalent inhibitor NM283 (Valopici- tabine) Idenix/Novartis Phase II NS5B polymerase Nucleoside analogue (chain terminator) JTK-103 Japan Tobacco Phase II NS5B polymerase Non-nucleoside allosteric inhibitor HCV-796 ViroPharma/Wyeth Phase Ia NS5B polymerase Non-nucleoside allosteric inhibitor Host targets/immunomodulators Actilon (CpG-10101) Coley Pharmaceutical Group Phase Ib Toll-like receptor-9 Immunomodulator ANA245 (Isatoribine) Anadys Pharmaceu- ticals Phase Ib Toll-like receptor-7 Immunomodulator ANA975 Anadys Pharmaceu- ticals Phase Ia Toll-like receptor-7 Immunomodulator (prodrug of ANA245) a Development has been halted due to cardiotoxicity in monkeys.

Prevalence of chronic hepatitis B Approximately 400 million people worldwide are chronically infected with the hepatitis B virus (HBV), and approximately 1 million die annually of HBV-related disease. The worldwide preva- lence of hepatitis B virus ranges from 0.1% to 20% (1). This wide range is largely due to differences in age at the time of infection. Following acute HBV infection, the risk of developing chronic infec- tion varies inversely with age: 90% for perinatal infection, 25–50% for infection at age 1–5 years and 1–5% for all others (2). About 45% of the world population live in areas where chronic HBV is highly endemic (≥8% of the population have the hepatitis B surface antigen (HBsAg), 43% live in intermediate-endemicity areas (2–7% HBsAg-positive) and 12% live in low-endemicity areas (0.6% to <2% HBsAg-posi- tive). Intermediately endemic areas include eastern and southern Europe and the Russian Federa- tion, while northern and western Europe have low endemicity (see Table 1). Table 1. Prevalence of hepatitis (2) Areas of endemicity Prevalence of HBV carriers Predominant modes of transmission Central Asian republics, parts of eastern Europe High (≥8%) Perinatal Childhood (horizontal) Western and northern Europe Low (<2%) Sexual contactInjecting drug use Other countries Intermediate (2–7%) Early childhood (horizontal) 2. Modes of transmission and risk factors HBV is detected in blood and body fluids (semen, saliva, nasopharyngeal fluids), and it can be transmitted either sexually or by exposure to infected blood or fluids. There are four major modes of transmission: • sexual contact • mother-to-child transmission at birth • parenteral (blood-to-blood) • through other infected bodily fluids. The world’s predominant mode of HBV transmission is perinatal. If a pregnant woman is an HBV carrier and is also hepatitis B e antigen (HBeAg)-positive, her newborn baby has a 90% likelihood of being infected and becoming an HBV carrier. Of these children, 25% will die later from chronic liver disease or liver cancer (2). Other risk factors favouring HBV transmission include: • receiving blood and/or blood products • drug-injecting, tattoos and other skin-piercing activities • unprotected penetrative sex, in particular anal and vaginal sex • organ transplants • health care occupational risks • haemodialysis. In low-endemicity areas, the highest incidence of HBV infection is among teenagers and young adults. The most common modes of transmission among these two groups are sexual transmission and blood-to-blood transmission due to injecting practices (2). hiv/aids tReatment and caRe cLinicaL pRotocoLs foR the Who eURopean Region 278 Liver cancer (HCC) Acute infection Chronic infection Cirrhosis Liver transplanta- tion Death Liver decompen- sation >90% of children <5% of adults (7) 23% in 5 years (8) 30% (7) 5–10% (7, 9) HCC: hepatocellular carcinoma. 3. Genotypes HBV is classified in seven major genotypes, A–G. Genotypes A and D are the most common types in Europe. The seroconversion rates of hepatitis B e antigen (HBeAg) and the rates of morbidity and mortality related to liver disease are similar in patients with genotypes A and D. However, sustained biochemical and virological remission are more common in patients with genotype A who have had HBeAg seroconversion than in the corresponding genotype D patients (3). No correlation between HBV genotypes and response to lamivudine or adefovir treatment has been demonstrated, as it has been with interferon. 4. Epidemiology of HBV infection in HIV-infected patients HBV and HIV have common routes of transmission and endemic areas, but HBV is about 100 times more infectious. Consequently, more than 70% of HIV-infected people have a blood marker of past or present HBV infection (2, 4). Men who have sex with men (MSM) show higher rates of HBV/ HIV coinfection than injecting drug users (IDUs) or heterosexuals (5). The risk of chronic hepatitis B is greater in cases of HBV/HIV coinfection and congenital or acquired immunosuppression as a result of lymphoproliferative disease, immunosuppressant drugs or maintenance haemodialysis. HBV-related liver diseases (including cirrhosis and its complications) is more progressive in cases of HIV coinfection than in monoinfection (6). 5. Natural course of HBV infection After an acute HBV infection acquired in adulthood, 90–95% of adults develop a broad, multispe- cific cellular immune response that eliminates the virus and ultimately leads to the development of protective antibodies for hepatitis B surface antigen (HBsAg). Less than 1% of those who have had an acute infection develop a fulminant hepatitis, and the remaining 5–10% become chronically infected (2). 5.1. Complications of chronic hepatitis B After an average of 30 years, 30% of patients with chronic active hepatitis B will progress to cir- rhosis. Liver failure decompensation occurs in about one quarter of cirrhotic patients with hepatitis B over a five-year period; another 5–10% will go on to develop liver cancer (see Fig. 1). Without treatment, approximately 15% of patients with cirrhosis will die within 5 years. Fig. 1 . Natural course of chronic HBV infection management of hepatitis b and hiv coinfection 279 A number of patients with chronic hepatitis B will develop hepatocellular carcinoma (HCC). Those at increased risk for developing HCC include adult males with cirrhosis who contracted hepatitis B in early childhood. Between 60% and 90% of HCC patients have underlying cirrhosis, but only 5% with cirrhosis will develop HCC. Up to 80% of liver cancers in the world are due to HBV. The median survival frequency of HCC patients is <3 months without appropriate treatment, which in- cludes surgery, percutaneous treatments, hepatic irradiation and chemotherapy (2). 5.2. Evolutionary phases of chronic hepatitis B Chronic hepatitis B generally develops over many years, during which time patients pass through a number of phases, as illustrated in Fig. 2 below (2). • The immunotolerant phase occurs in younger individuals who are HBeAg-positive, have a high HBV deoxyribonucleic acid (DNA) levels (2 x 104–2 x 108 IU/ml), and persistently normal ala- nine aminotransferase (ALT) levels. • The immunoactive phase with HBeAg-positive or HBeAg-negative chronic hepatitis B, mild HBV DNA levels (2 x 103–2 x 107 IU/ml) and persistently elevated ALT levels; the patient is at times symptomatic. • The non-replicative phase, corresponding to inactive HBsAg carriers. During HBeAg serocon- version, be it spontaneous or under pressure from treatment, there is an inactive HBsAg carrier state in which HBeAg is negative. During this period, HBV DNA is typically <2 x 103 IU/ml (often undetectable), with a normal or mildly elevated ALT level. A small number of long-estab- lished chronic carriers apparently terminate their active infection and become HBsAg-negative (up to 1% per year) (7). Fig. 2. Evolutionary phases of chronic hepatitis B infection (2) Inactive Phase Immunoactive PhaseTolerance DNA ALT Cure Anti-HBeAbHBeAg HBsAg Anti-HBs ALT: alanine aminotransferase; DNA: deoxyribonucleic acid; HBeAb: hepatitis B e antibody; HBeAg: hepatitis B e antigen; HBsAb: hepatitis B surface antibody; HBsAg: hepatitis B surface antigen. HBV infection in adults generally consists of: • an early replicative phase with active liver disease (HBeAg-positive chronic hepatitis B) • a late low- or non-replicative phase with HBeAg seroconversion • remission or inactivation of liver disease. Seroconversion from HBeAg to hepatitis B e antibody (HBeAb), either spontaneously or with treat- ment, is typically accompanied by: • a decline in HBV DNA levels (<19 IU/ml or <105 copies/ml) • normalization of liver enzymes • resolution of necroinflammatory activity on liver histology. hiv/aids tReatment and caRe cLinicaL pRotocoLs foR the Who eURopean Region 280 The rate of spontaneous resolution of active replication and seroconversion from HBeAg to HBeAb is 5–20% per year. During this process, some individuals develop an escape variant, a consequence of emerging mutations in the precore region that disrupts HBeAg production. These precore and core mutant viruses develop under selective immune pressure and are able to retain high levels of HBV replication (8). Patients thus affected – HBeAg-negative chronic hepatitis B patients – are clinically identified by the absence of HBeAg and the presence of HBeAb and high HBV DNA levels. This particular pattern is most commonly seen in eastern Asia and southern Europe because of the higher prevalence of non-A genotypes there, which predisposes the population to this muta- tion. 6. Reciprocal impact of HIV and HBV 6.1. Impact of HIV infection on HBV disease progression • HBV infection is more frequent and more severe in the HIV-infected (6, 9). • In HBV/HIV-coinfected patients, necroinflammatory activity in the liver tends to be milder, but higher HBV replication results in more severe liver fibrosis with increased risk (4.2 times greater) for cirrhosis with a more rapid progression to end-stage liver disease. • In HBV/HIV-coinfected patients with cirrhosis, hepatocellular carcinoma (HCC) may appear more aggressive and at an earlier age than in those not HIV-infected. In addition, it presents with multifocal lesions more frequently (10). • HIV appears to be a risk factor for reactivation of hepatitis B in patients who have developed hepatitis B surface antibodies (HBsAb, which 60–70% of HIV-infected individuals have), espe- cially in patients with severe immunodeficiency (11). • Patients coinfected with HIV 1 and HBV, especially those with low CD4+ nadir counts, are at increased risk for liver-related mortality. 6.2. Impact of HBV infection on HIV disease progression • The majority of the clinical studies that have examined the influence of HBV on HIV disease progression and consider HBsAg a marker of chronic HBV infection have not been able to prove that HBV has any role in HIV disease progression (6). • There is, however, an increased risk for liver disease-related morbidity and mortality in hepati- tis-coinfected HIV patients, as well as more hepatotoxicity under antiretroviral treatment regi- mens or when active treatment from both HIV and HBV is interrupted. management of hepatitis b and hiv coinfection 281 II. Identification of HBV/HIV 1. Assessment of HBV risk and diagnosis of hepatitis B in HIV-infected patients 1.1. Initial laboratory assessment of HBV status All HIV-infected patients should be: • tested for HBsAg (the presence of HBsAg for a minimum of 6 months indicates chronic hepa- titis B); • tested for hepatitis B core antibodies (HBcAb); and • assessed for previous HBV vaccination (HBsAb). HBcAb alone without HBsAg could be due to occult hepatitis. In this rare situation, HBV DNA is recommended (see below). 1.2. Evaluation of HBV disease severity Further evaluation is essential for making a decision regarding treatment, focusing on in-depth laboratory diagnosis and clinical evaluation. 1.2.1. Clinical evaluation for signs and symptoms of advanced liver disease Examination for signs and symptoms of liver disease is required. The presence or absence of clini- cal evidence for cirrhosis might be the key issue in defining treatment strategy in HBV/HIV-coin- fected patients. The clinical signs of cirrhosis are: • enlargement and dysmorphy of the liver; • portal hypertension (hepatic encephalopathy, digestive haemorrhage due to oesophageal varices and splenomegaly); • vascular spiders, palmar erythema and digital hippocratism (mostly in alcoholic liver cirrhosis rather than viral liver cirrhosis); and • jaundice, ascites, oedema and a tendency to bleed. The Child-Pugh classification is a simple, convenient prognostic measure in patients with liver cir- rhosis (see Table 2). It may be used to predict patient survival rates and is interpreted thus: • Class A (5–6 points) → compensated cirrhosis • Class B (7–9 points) → compensated cirrhosis • Class C (10–15 points) → decompensated cirrhosis.

ALt level • Serial measurements are preferred, as ALT may fluctuate significantly. • Elevated ALT is a marker of liver inflammation. • An ALT level three times the upper normal limit is correlated with a cirrhosis risk. • Normal ALT levels can also be associated with liver disease progression, particularly in HBeAg- negative patients. • Liver enzymes should be monitored on a regular basis, every six months for normal ALT lev- els. If liver enzymes become abnormal for a period of at least three months, HBV treatment is required. 1.2.3. Determination of HBeAg • HBeAg-positive patients almost invariably have high HBV DNA levels independent of their ALT levels. • HbeAg-negative patients may also have progressive liver disease. • However, in both situations detection and measurement of HBV DNA should be performed, as combining serological test results with DNA levels can determine treatment strategy. In limited- access settings, HBV DNA determination should be privileged. 1.2.4. HBV DNA level • Results should be expressed in international units (IU) per millilitre (1.0 IU = 5.4–5.8 copies/ml, depending on assay), the WHO standardized quantification unit for HBV DNA, and in decimal logarithm (log10) IU/ml for precise assessment of baseline and significant HBV DNA changes upon treatment. • If HBV DNA is initially found to be <2000 IU/ml, especially in patients with elevated ALT or other signs of liver disease, serial measurements should be undertaken at least semiannually, since such patients may exhibit wide fluctuations in HBV DNA. • Different tests produce different absolute results; consequently, the thresholds given for thera- peutic goals can only be indicative. • A single type of HBV DNA assay should be used for monitoring a patient. If a change of assay is planned, both tests should be used in parallel for at least two subsequent samples. • If only HBcAb is present at the initial assessment, it may be indicative of occult HBV infection (see Table 3). Occult HBV is usually assumed when HBV DNA is detected at low levels by highly sensitive techniques and in the absence of HBsAg. Occult HBV is found more frequently in HIV-positive patients than in HIV-negative patients, but its clinical relevance is uncertain. Currently, there is no evidence for the need to routinely detect or treat occult HBV. Table 3. Classification of chronic hepatitis B virus infections based on laboratory determinants (13) HBsAg HBsAb HBcAb HBeAg HBeAb HBV DNA Chronic active hepatitis B HBeAg-positive patients + – + + – + HBeAg-negative patientsa + – + – + + Occult HBV infection – – + – + +b Inactive HBV carrier state + – + – + – a Precore mutant HBV strain; b only detected by polymerase chain reaction (PCR) methods. • Patients with HBeAg-negative chronic HBV are distinguished from inactive HBV carriers by the presence of >104 HBV DNA copies/ml (or >2000 IU/ml), elevated ALT and necroinflam- matory liver disease. The literature suggests that HBeAg-negative chronic hepatitis B entails a particularly high risk of progressive hepatic fibrosis (14, 15). In contrast, inactive HBV carriers usually have undetectable HBV DNA. management of hepatitis b and hiv coinfection 283 1.2.5. Ultrasound and other evaluations Ultrasound examination of the liver (if possible Doppler ultrasound examination) can reveal: • cirrhosis: dysmorphy of the liver • steatosis: hyperechogenic liver • possibly early HCC: nodular unique or rarely multiple lesions. Where available, patients with liver cirrhosis should also have: • serum alpha-fetoprotein (AFP) assessment to detect HCC; and • upper gastrointestinal endoscopy for detecting the presence of oesophageal varices (with risk for gastrointestinal bleeding). In the presence of significant oesophageal varices, prevention of bleeding by non-cardioselec- tive beta blockers is recommended. The most frequently prescribed drug is propanolol at a dosage allowing a pulse reduction of at least 25–30% (40–160 mg daily may be necessary) (16). 1.2.6. Histological evaluation There are a number of advantages of liver biopsy, including: • wide availability; • assessment of necrosis, inflammation and fibrosis; • elimination of other causes of liver damage (opportunistic agents, drug toxicity, alcohol, steato- sis, etc.); • assessment of patients with consistently normal ALT levels who are HBV/HIV-coinfected and have liver cirrhosis. Activity and fibrosis are two major histological features of chronic hepatitis included in proposed classifications. Interpretation of liver biopsies using the Metavir scoring system (see Table 4) improves consistency in the interpretation of hepatic fibrosis, with a somewhat weaker reproduc- ibility for the hepatic inflammation grade. The fibrosis stage and inflammatory grade are correlated in two thirds of patients. Table 4. Metavir classification: activity and fibrosis scoring (17) Activity score (A) Lobular necrosisAbsent (0) Moderate (1) Severe (2) Parcellar necrosis Absent (0) A0 A1 A2 Minimal (1) A1 A1 A2 Moderate (2) A2 A2 A3 Severe (3) A3 A3 A3 A0 = no histological activity; A1 = minimal activity; A2 = moderate activity; A3 = severe activity.

(18). hiv/aids tReatment and caRe cLinicaL pRotocoLs foR the Who eURopean Region 284 Noninvasive methods for measuring markers of fibrosis (such as FibroTestTM) or liver stiffness (such as FibroScanTM) have been shown to provide an adequate estimate of the extent of fibrosis. If these methods are available, they can substitute for performing a liver biopsy (19-22) (see Table 4a). See section III below for two algorithms for HBV diagnosis in HIV-infected patients, as well as treatment options for coinfected patients. 1.2.7. Clinical situations not requiring histological evaluation Decision to initiate HBV treatment does not require histological evaluation for every patient. In particular, HBV treatment may be considered without a liver biopsy when: • there are clinical signs of cirrhosis; • the CD4 count is <350 cells/mm3 and antiretroviral treatment is indicated (see section III.3.1 below); or • there are no clinical signs of cirrhosis and the CD4 count is >350 cells/mm3, ALT is more than twice the normal upper limit and HBeAg is positive. 2. Evaluation of comorbidities and co-conditions 2.1. Psychiatric disorders • Psychiatric disorders are not a contraindication for HBV treatment. • Patients needing interferon (IFN) should be evaluated for psychiatric disorders. IFN should be avoided for patients with acute psychiatric disorders, and deferred for patients with moderate to severe depression until the condition improves. 2.2. Alcohol abuse • Assessment of alcohol intake is an important part of evaluation (see Protocol 6, Management of hepatitis C and HIV coinfection, Annex 3). • Heavy alcohol intake (≥50 g/day) contributes to fibrosis of the liver and can be identified by biopsy in patients with HBV independently of other predictors. This intake is equivalent to five or more drinks per day. One drink is defined as 330 ml (12 oz) of beer, 150 ml (5 oz) of wine, or 38 ml (1.25 oz) of hard liquor, containing approximately 10 grams of alcohol. • There is evidence of a synergistic (more than additive) interaction between heavy alcohol con- sumption (≥80 ml/day) and chronic HBV or hepatitis C virus (HCV) infections (23). • Alcohol consumption increases HBV replication, accelerates fibrogenesis and liver disease pro- gression in hepatitis B and C, as well as diminishing the response and adherence to anti-hepatitis treatment (especially if consumption is >50 g/day). • Active alcohol intake is considered a relative contraindication for interferon-based treatment. This recommendation is based on the documented non-compliance of heavy drinkers with vari- ous medical therapies, and the fact that the side-effects of interferon treatment already make compliance extremely difficult (24). • Psychological, social and medical support should be offered to stop alcohol intake or reduce it to under 10 g/day. 2.3. Drug use • Patients on opioid substitution therapy should not be excluded from treatment. • Initiation of HBV treatment in active drug users should be considered on a case-by-case basis (see Protocol 5, HIV/AIDS treatment and care for injecting drug users). • Psychological and social support by a multidisciplinary team should be provided for such patients. management of hepatitis b and hiv coinfection 285 2.4. other comorbidities and co-conditions Testing for comorbidities should include a comprehensive medical history that focuses on cofactors associated with more progressive liver injury, and it should cover other viral liver diseases, tuber- culosis (TB) (see Protocol 4, Management of tuberculosis and HIV coinfection) and pregnancy. Serological testing for hepatitis delta virus (HDV) might be suggested in chronically HBV-infected patients, especially IDUs. In case of persistent elevated ALT despite correct HBV treatment, pe- gylated interferon (PEG-IFN) can be added to antiretrovirals (ARVs), but efficacy and tolerability have not been assessed in HIV-coinfected cases (25). 3. Assessment of HIV risk and diagnosis of HIV/AIDs in HBV patients All patients with HBV should be offered HIV testing and counselling because the infections share routes of transmission, and because HIV accelerates HBV progression. Health care providers should explain to patients the reasons for offering the test and its importance for correct clinical manage- ment. However, a patient has a right to refuse an HIV test. The initial assessment of HIV status should include: • pretest counselling; • serological tests (typically, enzyme-linked immunosorbent assay (ELISA) and/or rapid tests) for HIV antibodies, followed by a western blot confirmatory test; and • post-test counselling irrespective of the result, including information on reducing risky behav- iour. Further clinical evaluation of HIV-infected patients is required to develop a clinical manage- ment strategy for HBV/HIV-coinfected patients. For detailed information, see Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents. hiv/aids tReatment and caRe cLinicaL pRotocoLs foR the Who eURopean Region 286 III. Clinical management of HBV/HIV patients By the end of the laboratory and clinical evaluation, patients can be put into one of three treatment categories: 1. not requiring hepatitis B or HIV treatment 2. requiring only hepatitis B treatment 3. requiring only HIV treatment or both hepatitis B and HIV treatment. For clinical management of patients with HBV/HIV coinfection the key issue is the treatment of HBV and HIV and a strategy for its initiation. This decision should be based on analysis of the following parameters: • HBV DNA levels • severity of liver disease • CD4 count and indications for antiretroviral treatment (ART) • contraindications. HBV treatment should be considered for any HBV/HIV-coinfected patient with evidence of active liver disease (high ALT level, significant serum HBV DNA level, necro-inflammation lesions or fibrosis in liver biopsy), irrespective of the CD4 count. 1. Coinfected patients not requiring treatment These patients have the following status: • CD4 count of ≥350 cells/mm3; and • mild or not progressing HBV disease (HBV DNA <20 000 in HBeAg-positive patients, or HBV DNA <2000 in HBeAg-negative patients; normal ALT; no severe liver disease if a biopsy has been performed). Since there is no immediate need for treatment, the patient’s health should be carefully monitored by: • a CD4 count every three to six months; • clinical monitoring of HIV-related symptoms every three to six months; • ALT measurements every six months for patients with inactive HBV infection (since liver disease may reactivate even after many years of quiescence), and AFP or ultrasound for HCC. • HBeAg-positive patients with elevated ALT levels and compensated liver disease should be observed for three to six months for spontaneous seroconversion from HBeAg to HBeAb prior to initiation of treatment. 2. Coinfected patients requiring only hepatitis B treatment HBV/HIV-coinfected patients needing only hepatitis treatment have the following features: • CD4 count of >350 cells/mm3; • HbeAg-positive and HBV DNA >20 000 IU/ml, or HbeAg-negative and HBV DNA >2000 IU/ ml; • clinical cirrhosis and detectable HBV DNA (>200 IU/ml); and • histologically proven active disease (Metavir score ≥A2 or F2), or persistently elevated ALT levels in the absence of other causes of ALT elevation. 2.1. Anti-HBV drugs for treatment of hepatitis B in HIV-coinfected patients not requiring ARt (doses and schedules) Since no large-scale randomized controlled trials have been conducted to determine the efficacy of anti-HBV drugs in HBV/HIV-coinfected patients, recommendations for treatment and monitoring management of hepatitis b and hiv coinfection 287 need to be derived from what data are available plus what is already known about the treatment of HBV mono-infected patients. Three antiviral drugs are recommended for use, PEG-IFN-α 2a, standard IFN-α 2a or 2b, and adefovir (ADF). 2.1.1. IFN and PEG-IFN The highest effectiveness of interferon has been demonstrated in patients with HBeAg, ALT lev- els more than twice the upper limit of normal and low HBV DNA levels. PEG-IFN is becoming a standard treatment for HBV, and it is the preferred option in patients with these features and a CD4 count of >500/mm3. Dosage and administration of PEG-IFN-α 2a (26) are: • 180 µg/week for 48 weeks, independent of HBeAg/HBeAb status. Dosage of INF-α 2a or 2b (26) is: • for HBeAg-positive cases, 10 million units (MU) subcutaneous 3 times weekly, or 5 MU daily for 4–6 months; and • for HbeAg-negative cases, same dosage for 12 months. 2.1.1.1 Contraindications Absolute contraindications are: • pregnancy and breastfeeding; • decompensated liver disease (due to an increased risk for thrombopenia, death from liver failure or sepsis); • uncontrolled psychiatric disease; • significant leukopenia or thrombocytopenia; • unstable coronary artery disease, diabetes or hypertension; or • uncontrolled seizure disorder. Relative contraindications are: • autoimmune diseases (e.g. psoriasis and rheumatoid arthritis) • prior history of depression or psychiatric illness. 2.1.2. Adefovir (ADF) With ADF, a nucleotide analogue, a progressive and efficient suppression of HBV DNA is observed. The rate of HBV-resistant strains is very low in the short term (3% after 2 years) but has recently been shown to be as high as 28% after five years of monotreatment (27). ADF dosage is 10 mg orally once daily (28). • The optimal duration of treatment is indefinite in the absence of other treatment. • It is recommended to continue treatment with ADF for at least 12 months. • ADF dosage should be adapted to creatinine clearance (CrCl): ° if CrCl is 20–49 ml/min, 10 mg every 48 hours ° if CrCl is 10–19 ml/min, 10 mg every 72 hours ° if the patient is on haemodialysis, 10 mg every 7 days following dialysis. Contraindications are pregnancy and nephrotoxicity. hiv/aids tReatment and caRe cLinicaL pRotocoLs foR the Who eURopean Region 288 2.2. Evaluation and treatment algorithms for chronic hepatitis B in HIV-infected patients not requiring ARt 2.2.1. Algorithm 1 The approach in this algorithm focuses on a determination of HBV DNA (in the absence of clinical cirrhosis). See Fig. 3. Fig. 3.

ART can be considered for patients with CD4 counts of 350–500 cells/mm3 if PEG-IFN, IFN or ADF are not available. c Premature use of ART can expose patients to ART side-effects and a risk of developing HIV resistance to tenofovir (TDF) or lamivudine (3TC), which can compromise future ART. HBeAg management of hepatitis b and hiv coinfection 289 2.2.2. Algorithm 2 The second algorithm’s approach is focused on clinical evaluation, in particular for settings where HBV DNA is not available. This approach allows identifying those HBV/HIV-coinfected patients in need of hepatitis B treatment for whom a decision regarding treatment can be made without deter- mining the HBV DNA level (i.e. patients with clinical cirrhosis, and patients with no clinical signs of cirrhosis, but with elevated ALT levels and positive HBeAg). However, patients with suspected chronic hepatitis B (HBeAg-negative with ALT more than twice the upper limit of normal) should be referred to a higher level of medical care for evaluation of HBV DNA and the appropriate course of treatment. Fig. 4. Algorithm 2 a PEG-IFN or ADF is the best choice for HBV/HIV-coinfected patients who do not need ART. ART can be considered for pa- tients with CD4 counts of 350–500 cells/mm3 if IFN or ADF are not available. b Premature use of ART can expose patients to ART side-effects and a risk of developing HIV resistance to TDF or 3TC, which can compromise future ART. c In case of negative HBeAg, the further diagnostic algorithm is the same as shown in Algorithm 1.

Prolonged treatment is, however, associated with 28% drug resistance after five years in monoinfected patients. Thus, close monitoring for HBV DNA is recommended every six months in order to detect drug resistance in case of a viral load increase of more than 1 log, in which case genotyping should be performed. Interferon is contraindicated in patients with decompensated liver disease due to its very poor tolerability profile. 3. Coinfected patients requiring only HIV or both hepatitis B and HIV treatment For these patients medication decisions are based on recognition of the dual effect of some antiret- roviral drugs on HBV and HIV viruses, such as lamivudine (3TC) and tenofovir (TDF) (30-32). 3.1. Considerations regarding treatment of hepatitis B 3.1.1. symptomatic patients with a CD4 count of 200 – 350 cells/mm3 The decision to treat for HBV is mainly based on HBV DNA levels. • In HBeAg-positive patients with HBV DNA >20 000 IU/ml and HBeAg-negative patients with HBV DNA >2000 IU/ml, the ART regimen must include two dual-activity drugs (anti-HBV and anti-HIV). • In patients with low levels of HBV DNA, an ART regimen containing two dual-activity drugs is optional but highly recommended in anticipation of an early switch due to a reactivation of hepatitis. 3.1.2. Patients with CD4 count < 200 cells/mm3 When CD4 count is <200 cells/mm3 and ART has been initiated there is a risk of a severe reactiva- tion of hepatitis B during immune reconstitution, which may include a life-threatening hepatitis flare. Irrespective of indications for HBV treatment, the ART regimen for these patients must there- fore include two dual-activity drugs in order to minimize the risk of HBV reactivation. 3.1.3. HIV-infected patients with clinical evidence of cirrhosis • Clinical cirrhosis is an absolute indication for treatment. • The HBV DNA threshold for initiation of HBV treatment is lower than in patients without cir- rhosis (over 200 IU/ml, i.e. as soon as detectable). • No medications are contraindicated for patients with compensated cirrhosis. • Patients with decompensated cirrhosis should be referred for palliative care. • Patients with cirrhosis require clinical observation, liver function monitoring and drug monitor- ing. • It might be necessary to adjust the dose of ARV metabolized by the liver. If this is not feasible, then didanosine (ddI) and stavudine (d4T) have to be avoided and a regimen with a protease inhibitor (PI) should be closely monitored (see Protocol 6, Management of hepatitis C and HIV coinfection for recommendations on antiretroviral dosage adjustment in patients with end-stage liver disease (ESLD). 3.2. Considerations regarding treatment of HIV infection 3.2.1. Initiation of HAARt Initiation of ART in HBV/HIV-coinfected patients should follow the current recommendations for HIV-monoinfected patients (see Table 5). (For further details, please refer to Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents.) management of hepatitis b and hiv coinfection 291 Table 5. Recommendations for initiating HAART in HBV/HIV-coinfected patients CD4 count Recommendations ≤200 cells/mm3 Antiretroviral treatment is recommended. ART regimens should contain two dual-activity drugs (targeting both HBV and HIV). 200–350 cells/mm3 Antiretroviral treatment should be considered with a high viral load or rapid decline in CD4 count, but should be started before the CD4 count falls to less than 200 cells/mm3. If HBV treatment is indicated, ART regimens containing two dual-activity drugs are also indicated or highly recommended. 3.2.2. First line HAARt regimens Table 6. First-line HAART for HBV/HIV-coinfected patients ARV drug classes HAART regimens Preferred first line 2 NRTIs + 1 NNRTI TDFa + (3TC or FTCb) + EFVc Alternative first line 3 NRTIs ZDV + (3TC or FTCb) + TDF a If TDF is not available, 3TC should be a mandatory component of the regimen. b FTC is equivalent to 3TC and is available together with TDF as a fixed-dose combination (33, 34). c Nevirapine (NVP) can be considered instead of efavirenz (EFV) for patients without hepatic dysfunction and with close moni- toring. It should be avoided in women with CD4 count >250 cells/mm3 or in men with CD4 count >400 cells/mm3. 3.2.3. second line HAARt regimens Table 7.

HIV-infected patients with 3tC-resistant HBV strains • 3TC (lamivudine) resistance develops more rapidly in HBV/HIV-coinfected patients, and even at the higher doses (300 mg daily), it appears in almost 50% and 90% of coinfected patients after two and four years, respectively, of 3TC treatment (36, 37). • In the presence of suspected lamivudine resistance, the first step is to confirm it, if resistance testing is available (38, 39). Otherwise resistance may be suspected if the HBV viral load increases more than 1 log in a compliant patient taking 3TC, and the patient should be switched to TDF (40–42). • TDF is the essential ARV for the HAART regimen in 3TC-resistant patients. hiv/aids tReatment and caRe cLinicaL pRotocoLs foR the Who eURopean Region 292 4. Monitoring and evaluation of HBV/HIV-coinfected patients 4.1. Hepatitis B treatment response Relevant response is defined as: • durable normalization of ALT levels; • sustained HBV DNA suppression (at least a 1 log decrease of HBV DNA after three months of treatment and an undetectable viral load <200 IU/ml in the long term) (43); • durable HBeAb seroconversion in initially HBeAg-positive patients, very rarely observed with nucleotide–nucleoside analogues and in HIV-positive patients. 4.1.1. Monitoring of HBV DNA See Table 8. Note in addition the following: • In HBeAg-positive patients with HBV DNA <20 000 IU/ml and in HBeAg-negative patients with HBV DNA <2000 IU/ml, DNA levels should be monitored every six months. • In patients on treatment (including ARVs with anti-HBV activity), an initial response is defined as at least 1 log drop in HBV DNA levels within one to three months. HBV DNA should then be measured at least every six months and if possible every three months. • Resistance should be suspected in compliant patients if HBV DNA levels increase by 1 log or more. If possible, resistance testing should be performed. Table 8. Monitoring during treatment Before treatment Month 1 Month 2 Month 3 Every three months Every six months Efficacy ALT X X X X HBV DNA X X X(if available) X 4.1.2. Monitoring of ALt • If the ALT level was initially normal, it should be carefully monitored after one month, then every three months over the course of treatment, and every three to six months if no treatment is indicated. • For patients receiving PIs and/or non-nucleoside reverse transcriptase inhibitors (NNRTIs), serum aminotransferase level follow-up is warranted every month during the first three months of starting any new ART; after this, a follow-up should be performed every three months to identify any drug-related hepatotoxicity. 4.2. Monitoring and evaluation of ARt in HBV/HIV-coinfected patients • CD4 cell count should be monitored every three to six months. • HIV viral load (if available) should also be monitored every six months. Please refer to the Protocol 1, Patient evaluation and antiretroviral treatment for adults and ado- lescents for further information. 4.3. Monitoring of adherence to treatment • Patient counselling is important to avoid discontinuation of HBV drug regimens. • Patients should be counselled about the side-effects and toxicity of HBV and ARV drugs and advised to consult a physician early for toxicity management. • If patients do not understand the signs of side-effects, they may not report them to their physi- cians, jeopardizing adherence, limiting treatment efficacy and increasing the risk of developing resistance. management of hepatitis b and hiv coinfection 293 For more information on adherence monitoring and support refer to Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents. 4.4. Management of hepatotoxicity All medical staff should be aware of the risk of side-effects to allow them to make early recom- mendations and interventions. Hepatotoxicity is a significant side-effect of ARV use that may increase morbidity and mortality among treated HBV/HIV-coinfected patients. The management of liver toxicity is based mainly on its clinical impact, severity and pathogenic mechanism. 4.4.1. Immune reconstitution in HBV/HIV-coinfected patients The liver damage induced by chronic HBV is mainly immune-mediated. The immunodeficiency caused by HIV infection is responsible for attenuating the inflammatory reaction in the liver of HBV/HIV-coinfected patients. The inhibition of HIV replication with ART leads to the syndrome of immune reconstitution, with clinical hepatitis following the first weeks after initiation of ART, typi- cally in patients with very low CD4 count and/or very high levels of HIV ribonucleic acid (RNA) before ART (44). These symptoms are usually prevented by including a dual-activity drug in the ARV regimen (see above). 4.4.2. Drug-related hepatotoxicity • Liver toxicity may also occur in patients receiving nucleoside or nucleotide reverse transcrip- tase inhibitors (NRTIs), especially d4T and ddI, and may lead to severe microsteatosis with lactic acidosis (in exceptional cases). The condition is potentially severe, with a high mortality rate, and in case of symptomatic lactic acidosis requires immediately switching to another ARV with a different toxicity profile. • The rate of severe hepatotoxicity (grade 3 or 4) associated with NNRTIs is relatively low but may be significantly higher in HBV- and HCV-coinfected patients (45, 46). • The major toxicities associated with nevirapine (NVP) are hepatotoxicity and hypersensibility reactions (rash); both may be severe and life-threatening. Symptomatic NVP-associated hepatic or serious rash toxicity, although uncommon, is three to seven times more frequent in women than in men (47). • If CD4 >250/mm3, there is about 10 times greater risk of severe symptomatic hepatotoxicity than in patients with CD4 <250/mm3. • The risk of hepatotoxicity and rash are highest in the first six weeks of NVP treatment; starting NVP at half doses during the first six weeks minimizes the risk. • Elevated serum aminotransferase levels are relatively common in HIV-infected patients receiv- ing PI-based ART (2–8.5% of PI-treated patients) (48, 49). • HBV/HIV coinfection has been associated with a high risk of developing drug-induced liver injury, and with a greater risk of severe liver injury than in patients who have concurrent liver disease from other causes. • If no other cofactors exist, the degree of hepatotoxicity is the main determinant of the clinical approach. (see Table 9). hiv/aids tReatment and caRe cLinicaL pRotocoLs foR the Who eURopean Region 294 Table 9. Standardized hepatotoxicity scale (50) Toxicity grade ALT and AST changes relative to the upper limit of normal Increase from baseline 1 1.25–2.5 times 1.25–2.5 times 2 2.6–5.0 times 2.6–3.5 times 3 5.1–10.0 times 3.6–5.0 times 4 >10.0 times >5.0 times • If hepatotoxicity is severe, switching the ART regimen to one with lower potential hepatotoxic- ity is recommended. • If hepatotoxicity is mild to moderate (grades 1 and 2), it is reasonable to continue the same ART regimen with a close follow-up of liver enzymes. 4.4.3. Hepatotoxicity of tB drugs in the context of chronic HBV infection (51, 52) • The rate of hepatotoxicity is significantly higher in TB patients with HCV or HBV coinfection (59%) than in those without (24%) (52). • Commonly used anti-TB drugs, such as isoniazid, rifampicin, and pyrazinamid are hepatotoxic. • Pyrazinamide and isoniazid are the most hepatotoxic and should be avoided in TB patients with known chronic liver disease. • It is not necessary to adapt dosage of anti-TB drugs in cases of hepatic insufficiency. • In decompensated liver disease, a regimen without rifampicin should be used. • Streptomycin, ethambutol and a reserve drug such as fluoroquinolone can be used if treatment is necessary in patients with fulminant liver disease. Consultation with a specialist is required. • Alternative anti-TB drugs with lower hepatotoxicity may be used in case of liver dysfunction, for example, rifabutin, amikacin, ofloxacin and levofloxacin. The treatment of these special cases should be decided in consultation with an acknowledged expert. • Hepatotoxicity appears in the first two months of TB treatment, thus requiring close initial monitoring of liver functions. management of hepatitis b and hiv coinfection 295 IV. Suggested minimum data to be collected at the clinical level The suggested minimum data to be collected are important in the development of key indicators on access to treatment and its success. Such indicators assist managers in decision-making on ways to strengthen and expand these services to all those in need. The following data should be collected at each clinical facility on a regular basis (e.g. monthly, quarterly or semi-annually): • number of HIV patients (“seen for care” – this will be the denominator for the data below); • number of HIV patients coinfected with HBV (HbsAg-positive); • number of HIV-positive patients with active hepatitis; • number of HIV-positive patients with active hepatitis receiving: ° HAART with 3TC and/or TDF; ° ART without 3TC and/or TDF; ° exclusively on hepatitis B treatment (e.g. IFN or ADF); • number of HIV-infected patients vaccinated against HBV; and, • number of HBV/HIV coinfected patients who have died (in a given time period) including cause of death (e.g. liver-related deaths, HIV/AIDS related mortality or non-HIV/AIDS related mor- tality such as accident, overdose or suicide). hiv/aids tReatment and caRe cLinicaL pRotocoLs foR the Who eURopean Region 296 References 1.

Prevention of HePatitis a, B, C and otHer HePatotoxiC faCtors in PeoPle living witH Hiv 303 I. Prevention strategies The strategies for limiting the spread of hepatitis include: • vaccination against hepatitis B and A; • prevention of mother-to-child transmission of hepatitis B virus (HBV) and hepatitis C virus (HCV); • reducing risk of infection through safer sexual behaviour and reducing harm related to injecting drug use; • counselling to reduce liver-related harm; • prevention through transfusion of blood and blood products; and • prevention in health care settings. 1. Vaccination against hepatitis B and A 1.1. Hepatitis B All HIV patients not coinfected with HBV should be vaccinated against it. (See also Protocol 12, Immunization of people living with HIV and people at risk for HIV infection.) The schedule for HBV vaccine in HIV-infected adult patients (1, 2) is as follows. • HBV vaccination should start with the conventional dose (20 µg at months 0, 1 and a third time between months 6 and 12) for patients with a CD4 count >500 cells/mm3. • In individuals with CD4 cell counts between 200 cells/mm3 and 500 cells/mm3, an intensive vaccination schedule is recommended (20 µg at months 0, 1, 2 and 12). Patients who do not respond to this first cycle, measured by level of hepatitis B surface antibody (HBsAb) (<10 IU/ litre) should receive booster doses or start a new vaccination cycle with 40 µg at months 0, 1, 2 and 6–12 (3). • It is generally accepted that an adequate response to hepatitis B vaccine is the production of serum HBsAb at levels >100 IU/litre (or at least 10 IU/litre). Studies on vaccination in HIV patients have used either the 0/1/6-month or the 0/1/2/12-month hepatitis B schedule (3, 4). • Patients with CD4 counts <200 cells/mm3 should receive antiretroviral treatment (ART) first. Vaccination should be deferred until a clinically significant immune reconstitution has been achieved, preferably after the CD4 count has increased to >200 cells/mm3. • Compared to HIV-negative patients, those who are HIV-positive: ° are less likely to respond to HBV vaccine; ° have lower mean antibody titres (by a factor of about 30); and ° lose “protective” antibody levels more quickly (40% loss in one year versus 5% loss in those who are HIV-negative). • Routine or direct administration of booster doses is not recommended. Humoral response to HBV vaccine may decline progressively over time, and may put the patient at risk of acute infection in case of exposure. Yearly monitoring of HBsAb is recommended, and booster doses should be given when HBsAb <10 IU/litre. For further information on hepatitis B vaccine, please refer to Protocol 12, Immunization of people living with HIV and people at risk for HIV infection. Hepatitis B vaccine response correlates with CD4 count, as shown in Table 1. HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 304 1 Prisoners are at increased risk of HBV infection due to injecting drug use and unprotected sex. Table 1. Hepatitis B vaccine response at differing Cd4 counts (3,5) CD4 count (cells/μl) % of patients achieving HBsAb >10 IU/litre >500 87 >350 with standard dose 39 >350 with doubled dose 64 <350 26a a Physicians should weigh the risk of HBV infection against the benefit of vaccination in severely immunocompro- mised patients. Other adult populations at risk for HBV who should be vaccinated include: • sexual partners of HBV carriers • men who have sex with men (MSM) • sex workers (SWs) • other people with multiple sexual partners • patients with STIs • IDUs • prisoners, both male and female1 • patients on haemodialysis • health care workers exposed to blood or blood products. For HBV vaccination of children and use of hepatitis B immunoglobulin (HBIg), please refer to Protocol 12, Immunization of people living with HIV and people at risk for HIV infection. 1.2. Hepatitis A • All HCV/HIV- and HBV/HIV-coinfected patients who are not also coinfected with the hepati- tis A virus (HAV) but are at risk for it should be vaccinated (see the risk of HAV infection and further strategies in Protocol 12, Immunization of people living with HIV and people at risk for HIV infection). • The response rate to vaccination is reduced and correlates to CD4 count. • Mean HAV antibody titres in HIV-positive responders are about one tenth what they are in HIV- negative responders. • Although the absolute lower limit of antibody level required to prevent HAV infection has not been established, a study using a HAV antibody (Ab) threshold of 33 mIU/litre showed the lev- els of response in Table 2. Table 2. Hepatitis a vaccine response at differing Cd4 counts (6) CD4 count (cells/µl) % of patients achieving HAV Ab >33 mIU/litre Month 7 Month 9 ≥500 73 67 200–499 53 69 <200 11 9a a Physicians should weigh the risk of HAV infection against the benefit of vaccination in severely immunocompro- mised patients. Prevention of HePatitis a, B, C and otHer HePatotoxiC faCtors in PeoPle living witH Hiv 305 • Though response to vaccination in immunocompromised patients is reduced, WHO policy is to administer vaccine regardless of CD4 level. Immunoglobulin should be administered concur- rently for those with severe immunosuppression (CD4 cell count <200). • Non-responders to HAV vaccine should be revaccinated once their CD4 count has risen in response to HAART, ideally ≥500 cells/mm3. For HAV vaccination of children and use of hepatitis A immunoglobulin, please refer to Protocol 12, Immunization of people living with HIV and people at risk for HIV infection. There are certain contraindications that need to be kept in mind even though hepatitis A vaccine is inactivated and no special precautions are needed when vaccinating immunocompromised people. • HAV vaccine should not be administered to patients with a history of serious allergic reaction to it. • Vaccination of patients with moderate or severe acute illnesses should be deferred until their conditions have improved. • The safety of HAV vaccination during pregnancy has not been determined. However, because it is an inactivated vaccine, the theoretical risk to the fetus is low. The risk associated with vac- cination should be weighed against the risk of HAV infection. 2. Prevention of mother-to-child transmission (PMTCT) 2.1. PMTCT of HBV • All HIV-infected women should be screened for hepatitis B surface antigen (HBsAg) as a rou- tine part of prenatal testing. • In pregnant HBV/HIV-coinfected women who need or do not need ART for their own health, the antiretroviral (ARV) combination has to include 3TC, as it is effective against both viruses. • The transmission rate of HBV is reduced by replication suppression; the doses and duration at which ARVs are administered should be the same as for HIV mono-infected women (see Proto- col 10, Prevention of HIV transmission from HIV-infected mothers to their infants). • In children born to chronically HBV-infected mothers, administration of vaccine within 12 hours after birth provides up to 95% protective efficacy (7). Since the added value of adminis- tering HBIg concurrently with hepatitis B vaccine is quite low, its benefits and cost should be considered. • In cases in which the mother is HBsAg-positive, the neonate should receive the single-antigen HBV vaccine along with 0.5 ml of HBIg within 12 hours of birth. These children can then re- ceive the HBV vaccine series on a normal schedule of three doses (at 0, 1 and 6 months). In neonates weighing less than 2000 g, the initial vaccine following delivery is associated with a lower rate of immunogenicity. Therefore, these children should receive four doses of HBV vac- cine (at birth and 1, 2–3 and 6–7 months) (8). • Children of HBsAg-positive mothers should undergo testing for HBsAg and HBsAb at 9 and 18 months. If the surface antibody level is less than 10 mIU/ml, the entire three-vaccine series should be repeated. Testing for hepatitis B core antibody (HBcAb) in these children is discour- aged because passively acquired maternal antibodies may be detectable up to 24 months of age. • When a woman’s HBV status is still unknown at delivery but is later discovered to be positive, HBIg may be administered up to seven days after birth. In cases of unknown maternal hepatitis status among children weighing less than 2000 g at birth, physicians should administer both the HBV vaccine and immunoglobulin. • Neonates born to HBV-negative mothers should receive their first HBV vaccination in the hos- pital. Neonates weighing less than 2000 g are a prominent exception to this rule. Because of the reduced immunogenicity of the HBV vaccine in this group, vaccination should be delayed until one month of age (9). HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 306 2.2. PMTCT of HCV • HCV mother-to-child transmission (MTCT) in HIV-infected women is high (between 5% and 20%) (10). When possible, HCV treatment should be offered before pregnancy to women of childbearing age. Although several MTCT risk factors have been identified, there are currently no interventions available to prevent vertical transmission of HCV. • Normally, elective caesarean section is advised for women who are HIV-infected as a means of preventing transmission to the infant. However, if the viral load is <1000 copies/ml, then vagi- nal delivery could be considered. Based on the current evidence, these same guidelines apply for women who are HCV/HIV-coinfected (11, 12). • Prevention of ribavirin embryopathy includes: ° a pregnancy test before starting treatment and every month during treatment; and ° counselling (of both the woman and her partner) to avoid pregnancy and use condoms while either partner is taking ribavirin and for at least six months afterwards. 3. Preventing and reducing risk of infection 3.1. Safer sexual behaviour • All patients – those in the general population as well as those in vulnerable populations (SWs, IDUs, MSM, etc.) – should be counselled about safer sex and the use of condoms for any form of penetrative sex. Condoms are an effective means of preventing sexual transmission of HIV infection as well as hepatitis B and C infections. • The sexual transmission of hepatitis A is mostly found in MSM, linked to oro-anal contact; preventive measures include using either a vertically cut condom or some plastic food wrap to cover the anal area before oral contact. 3.2. Reducing harm related to injecting drug use • In addition to risks resulting from sexual behaviour, IDUs are vulnerable to bloodborne virus (HIV, HCV, HBV, HAV and HDV) as a result of collective use of injecting equipment. In some countries in Europe, over 70% of HIV infections are attributed to IDUs (13). • Effective evidence-based strategies to reduce risk of HBV and HCV transmission through injecting drug practices are: ° linking to harm-reduction programmes, particularly needle exchange and opioid substitu- tion therapy; and ° counselling of patients with high-risk drug and sexual practices, especially those who are seropositive, on risk reduction. For more details, please refer to Protocol 5, HIV/AIDS treatment and care for injecting drug users 4. Counselling to reduce liver-related harm All patients should be counselled on ways to reduce liver-related harm. • Alcohol consumption should be stopped or reduced to no more than 10 g/day. • Smoking should be stopped, as it has been associated with an increased risk of hepatitis cellular carcinoma (HCC) in some studies of patients with chronic HBV disease. The effects of smoking and alcohol may be synergistic (14). • The active component in cannabis – endocannabinoid (found in both marijuana and hashish) – has been found to have many physiological and patho-physiological functions. It has recently been implicated in the haemodynamic alterations occurring in cirrhosis (15). • No dietary factors have been linked specifically to HBV disease activity or severity. However, excess iron is associated with reduced responsiveness to interferon treatment and increased risk for HCC. Thus, iron supplements should be avoided unless iron deficiency is present (16). • Vitamin A in excessive amounts can be directly hepatotoxic; it is not recommended unless there is documented deficiency (17). Prevention of HePatitis a, B, C and otHer HePatotoxiC faCtors in PeoPle living witH Hiv 307 • Herbal supplements should be used with caution, if at all. Many of these preparations can be severely hepatotoxic (18), for example, chaparral, comfrey, germander, jin bu huan and kava kava. Due to a lack of regulation of supplements, formulations and doses can vary widely. • Patients who have coexisting non-alcoholic fatty liver disease should be simultaneously coun- selled on: ° optimizing body weight ° achieving and maintaining normal triglyceride levels ° controlling diabetes mellitus. 5. Prevention of transmission through transfusion of blood and blood products Precautions to prevent infection through blood and blood products include: • screening of all blood products for HBsAg and HCV Ab • screening for HBcAb, and HCV RNA quantification2 • virus inactivation of plasma-derived products. 6. Prevention in health care settings As it is not possible to identify all people infected with bloodborne pathogens, guidance to protect health care workers against HIV and hepatitis viruses is based on the concept that all patients should be assumed to be infectious. The application of universal precautions requires that all blood and body fluids be regarded as potentially infectious and that appropriate protective action be taken. Universal precautions include: • infection-control practices, such as appropriate sterilization of medical and dental equipment; • discouraging the excessive use of injections and promoting safe injection practices among health care workers; and • strongly recommending vaccination against hepatitis B for all health care workers exposed to blood or blood products. Prevention of hepatitis B and C transmission in health care settings is similar to prevention of HIV transmission there. For further information, please refer to Protocol 13, Post-exposure prophylaxis for HIV infection. 2 Even when this screening is performed, there is still a minor risk of transmission.

Introduction As the health and well-being of people living with HIV (PLHIV) improve due to antiviral treatment (ART), it has become necessary to reconsider many previous policies concerning their sexuality and reproduction. A rights-based approach to caring for their sexual and reproductive health (SRH) is needed to: • empower them as individuals; • ensure that they consider themselves capable of healthy and satisfying sexual lives through the effective management of their HIV infection; and • address other SRH concerns effectively. The purpose of this protocol is to assist health care providers at every level during consultations with PLHIV (whether or not on ART) on sexual and reproductive health. The present protocol in- cludes steps that should be taken during such consultations, based on WHO documents and avail- able evidence. 314 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION II. Background Reproductive health (RH) is concerned with the reproductive system and its processes and func- tions at every stage of life. The term implies that people should be able to have a satisfying, respon- sible and safe sex life, and that they should be able to reproduce and freely decide whether, when and how often to do so (1). Reproductive health overlaps but is not synonymous sexual health (2). Sexual health encompasses positive aspects of sexuality and sexual relationships, as well as problems with power dynamics in these relationships, including coercion, violence and discrimination. It concerns “the enhancement of life and personal relations, and not merely counselling and care related to reproduction and sexu- ally transmitted diseases” (1). In order to attain and maintain SRH, people must be empowered to exercise control over their sexu- ality and reproduction and have access to related health services (2). SRH services are offered by a variety of providers – from primary care physicians in western Europe to obstetricians, gynaecolo- gists, urologists, dermatovenerologists and sexologists in eastern Europe – at venues that include family planning centres, youth-friendly health centres and sexually transmitted infection centres. Reproductive health care providers should use any opportunity to promote voluntary testing and counselling for HIV infection and strive to improve access to care for PLHIV. HIV specialists should be informed of the reproductive rights and choices of PLHIV and refer them to appropriate RH services for quality assistance. In Europe, reproductive health services for drug-using women are particularly important. Female injecting drug users (IDUs) are difficult to reach through the usual RH services and may mistakenly perceive themselves as infertile because of drug-related amenorrhea. 315 support for sexual and reproductive health in people living with hiv III. Principles of SRH Services for PLHIV 1. General principles • Provision of RH services should follow the human rights principles of non-discrimination, par- ticipation and accountability. • Services should be comprehensive and client-oriented, addressing all the needs of PLHIV dur- ing their lifetime. • There should be no discrimination towards PLHIV, irrespective of any risk behaviours. • Women should not be forced to have an abortion because of their HIV status. • Confidentiality is to be a guiding principle in all services for PLHIV, including SRH services. These principles are based on recognition of the needs of PLHIV: • to obtain complete and correct information regarding their SRH choices • to have or not have children and to make informed decisions about the choice • to have access to the same full range of SRH services as HIV-negative people • to be treated without stigmatization or discrimination in health care settings • to expect confidentiality and respect for their human rights from health care providers • to be involved in the formulation of policies and programmes that affect them. 2. Principles of HIV testing and counselling HIV testing and counselling should be offered to clients and their partners during: • testing for or treatment of reproductive tract infections (RTIs) and sexually transmitted infec- tions (STIs); • contraceptive counselling, with an emphasis on the benefits of knowing one’s status when choosing a method of contraception; • pre-conception, for planned pregnancy and childbirth to minimize mother-to-child transmission (MTCT); • prenatal care, to maximize care for the mother and the prevention of MTCT (PMTCT);1 • newborn care, to facilitate safe choices regarding feeding options when HIV status is un- known; • consultation regarding options for unwanted pregnancies; • screening consultation for cervical cancer; and • outreach work, especially among groups at high risk of infection (e.g. IDUs, men who have sex with men (MSM) or sex workers). 1 For more information please refer to Protocol 10, Prevention of HIV transmission from HIV-infected mothers to their infants. 316 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 3. Patient counselling Every HIV-infected patient attending SRH services should receive appropriate counselling on sex- ual and reproductive health issues, such as: • reduction of risky sexual behaviour and safer sex negotiation, for both HIV-discordant and - concordant partners; • the causes and management of sexual dysfunction; • family planning and contraception; • cervical cancer screening; • STIs; • hepatitis B vaccination; • substance use; • interactions between ARVs and other drugs; and • interactions between contraceptives and illicit drugs. Psychological support should be provided during counselling, with referrals for further assistance as required. 317 support for sexual and reproductive health in people living with hiv IV. Sexual health of PLHIV Sexual health is affected by a variety of issues (3), including: • sexual well-being (satisfaction, pleasure and freedom from dysfunction) • HIV, other STIs and RTIs • mental health • violence related to gender and sexuality • physical disabilities and chronic illnesses • unintended pregnancy and unsafe abortion • infertility. 1. Taking a sexual health history A sexual history should be included when obtaining the medical history of PLHIV. It will help equip the provider to discuss risk-reduction strategies for preventing further transmission, such as reduc- ing the number of sexual partners or using condoms, and make appropriate referrals (4, 5). Health care providers should be non-judgemental of the range and diversity of their patients’ sexual practices and backgrounds. A provider’s attitude will affect the quality and effectiveness of care provided to PLHIV. Providers should: • be open and able to discuss sex and other sensitive issues • be prepared to take a comprehensive sexual history • be able to manage debilitating SRH problems that patients face (4) • be sensitive to the needs of PLHIV who may have suffered violence • have current information and refer patients to appropriate support (5, 6). It is a fundamental duty of all health workers to use their professional skills ethically and be aware of the laws in their country. The main ethical principles of the health care profession are: • do no harm • respect the rights of the patient • assure informed consent • maintain the highest degree of patient confidentiality. A list of recommended topics and suggested questions to use in obtaining a sexual history is pro- vided in Annex 1. 2. Sexual well-being While many of the sexual health issues faced by PLHIV are similar to those faced by their non-in- fected peers, some issues are particular to those living with HIV. 2.1. Sexual dysfunction among women The limited evidence available suggests that sexual dysfunction is common in women following disclosure of HIV infection. It may be attributed to: • psychological factors (including post-diagnosis depression, anxiety, irritability, loss of self es- teem, altered/disturbed body image, change of roles in couple relationship, social isolation and fear of infecting others); • medical factors (such as endocrinopathies and autonomic and peripheral neuropathies, gastroin- testinal symptoms and headache); • previous violence and associated fear and trauma; 318 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION • lipodystrophy, a side-effect of ART that can result in stigmatization and sexual isolation (7–9); and/or • infrequent sex, avoidance and non-communication (10). 2.2. Sexual dysfunction among males Among HIV-infected males, ART has been associated with low libido, erectile dysfunction and increased serum estradiol levels (11). Table 1. clinical signs of male sexual dysfunction Clinical signs Possible cause Historical Abrupt onset Psychogenic impotence (HIV diagno- sis, performance anxiety) Absent nocturnal/early morning erections Vascular or neurological disease Loss of erection after penetration Anxiety or vascular steal Exam Reduced femoral or peripheral pulse Vascular disease Testicular atrophy/loss of muscle bulk/loss of facial or body hair Hypogonadism Laboratory Low serum-free testosterone, high prolactin or abnormal thyroid- stimulating hormone (TSH) levels Endocrinologic dysfunction Abnormal lipids Atherosclerosis Source: Colson & Sax (12). 2.3. Interactions between erectile dysfunction drugs and ARVs Sexual dysfunction, including a decrease in sexual interest, has been noted in both females and males receiving ART regimens with PIs (13, 14). Switching HIV-infected patients to regimens that do not contain PIs may alleviate some symptoms associated with sexual dysfunction (15), while among some male patients, sildenafil or apomorphine hydrochloride may improve erections (16). Recreational use of Viagra (sildenafil) is common among some groups (17, 18). Prescription of ARVs and erectile dysfunction agents should be based on possible side-effects and drug interac- tions. 319 support for sexual and reproductive health in people living with hiv Table 2. interactions between erectile dysfunction agents and antiretroviral drugs Erectile dysfunction agent Agent dose ARV ARV dose Agent effect on ARV levels ARV effect on agent levels Potential clinical effects Management Sildenafil (Viagra) — Amprenavir — — Not studied; may increase sildenafil levels Increased sildenafil effects (hy- potension, priapism) Initiate silde- nafil at 25 mg QOD-OD and adjust dose as indicated; not recommended to exceed 25 mg in a 48- hour period. 25 mg x 1 dose Indinavir 800 mg TID Indinavir AUC: increased 11%; Cmax: increased 48% Sildena- fil AUC: increased 340%; Cmax: increased 300% (levels exceeded those achieved by a 100 mg single dose) Increased sildenafil effects (hy- potension, priapism) Initiate silde- nafil 30–45 minutes be- fore sex and adjust dose as indicated; not recommended to exceed 25 mg in a 48- hour period. — Lopinavir/ ritonavir — — Not studied; may increase sildenafil levels Increased sildenafil effects (hy- potension, priapism) Initiate silde- nafil 30–45 minutes be- fore sex and adjust dose as indicated; not recommended to exceed 25 mg in a 48- hour period. — Nelfinavir — — Not studied; may increase sildenafil levels.

Substance use When asking about sexual practice it is important to list all medications taken by a patient, includ- ing recreational, illicit and herbal/alternative drugs. Substance use by PLHIV may increase risky sexual behaviour and HIV transmission. If HIV-infected patients also receive ART or are about to initiate it, potential drug interactions should be considered and discussed with them. Table 3 sum- marizes some interactions between alcohol and ARVs and between marijuana and ARVs.

Appropriate psy- chological support should be an essential part of sexual dysfunction management, as not all PLHIV will need antidepressant therapy, and such support can facilitate a healthy sexual life. Some patients who have been referred for psychotherapy and prescribed antidepressants after their HIV diagnosis experience side-effects that include sexual dysfunction. More recently developed antidepressants with minimal drug interactions can be used when sexual dysfunction has been attributed to the older agents (6). 322 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Table 4. antidepressant agents with sexual dysfunction side-effects (men and women) Antidepressant Therapeutic dosage Potential clinical effects due to ARV interactions Fluoxetine (Prozac) 10–40 mg/day Increased delavirdine, ritonavir effects; possibly increased fluoxetine effects Paroxetine (Paxil) 10–40 mg/day Decreased paroxetine effect with fosamprenavir Sertraline (Zoloft) 50–100 mg/day Drug interactions unlikely with ARVs Venlafaxine XR (Effexor XR) 75–375 mg/day Increases in serum level of venlafaxine possible with RTV coadmin- istration Possible substitutions for individuals experiencing sexual dysfunction from other antidepressant agents Bupropion sus- tained release (Wellbutrin SR) Not to exceed 400 mg/day (in di- vided doses) due to increased risk of sei- zures, particularly in individuals who have other risk factors for seizures Clinically important drug interactions with PIs unlikely (preliminary in vitro data show weak inhibition by ritonavir) Mirtazapine (Remeron) 15–45 mg/day Increases in serum level of mirtazapine possible with ritonavir coad- ministration.

STIs and RTIs Management of STIs and RTIs should include the following components: • medical and sexual history • informed consent for testing and exam procedures • physical examination • testing for STIs and RTIs • preventive measures (such as hepatitis B vaccination) • treatment as needed, with consideration for potential ARV interactions • for STIs, partner notification and fulfilment of any public health obligations • counselling on risk reduction, and referral as appropriate • scheduling of follow-up visits and consultations. In general, the management of RTIs and non-HIV STIs for PLHIV is similar to that for other pa- tients, with several differences. • The clinical presentation of STIs may vary with HIV disease stage. • Longer therapeutic courses may be needed. • Potential drug interactions with ARV drugs should be evaluated. • Enhanced surveillance is necessary due to the rapid progress and frequent recurrence of infec- tions in PLHIV. There are special considerations for the management of syphilis, vulvovaginal candidiasis and bac- terial vaginosis in PLHIV; see Annexes 2–4. Among HIV-infected women, higher rates and/or greater severity of the following STIs and RTIs and their complications have been noted than among HIV-negative women: • pelvic inflammatory disease (PID)2 • human papillomavirus (HPV) infection, causing cervical dysplasia (22–24) • cervical intraepithelial neoplasia (CIN)3 • vaginal yeast infections. 2 PID is sometimes noted as a co-epidemic of HIV in some urban populations of reproductive age (6). 3 Rates are substantially higher among women in the advanced stages of HIV/AIDS (25). 323 support for sexual and reproductive health in people living with hiv Among MSM, increased levels of rectal chlamydial infection, syphilis, gonorrhoea, herpes simplex virus (HSV), lymphogranuloma venereum (LGV), anal dysplasia and genital herpes are common regardless of HIV status (26–32). In addition, anal cancer is strongly associated with HPV infection, and it is significantlsy more likely among MSM who are HIV-infected (33, 34). Testing procedures vary depending on resources and particular STI prevalence (see Table 5). Health care providers should accordingly consult local STI management guidelines for further advice.

Partner notification It is essential that every effort be made to treat the partners of those HIV-infected people diagnosed with other STIs; otherwise, the likelihood of STI reinfection is high. Following a safety assessment to consider the implications of notifying sexual partners (i.e. a risk assessment for intimate partner violence), and in accordance with local protocols and regulations, patients should be encouraged to ensure that their sexual partners are evaluated and treated. Partner management strategies are based on the premise that the sexual partners of people with STIs are likely to be infected with the same STIs, but that they may be asymptomatic, and that they may not otherwise seek care. The various options for partner notification and treatment should be discussed with the patient. Depending on the resources of the provider and the individual situation of the patient, options include: • the patient informing and accompanying a partner for testing; • provider-assisted notification followed by testing and treatment; and • in rare cases, expedited partner treatment in which the patient delivers medication to a partner without a clinical examination (36–38).4 4 This is not the preferred option due to the possibility of the partner’s coinfection with multiple STIs including HIV, implica- tions for drug interactions or allergies and medicolegal issues. 324 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 3.2. Interactions of STI/RTI drugs and ARVs If PLHIV are on ART, possible drug interactions with other STI treatment drugs should be consid- ered and discussed with them (see Table 6).

Violence related to gender and sexuality Gender- and sexuality-related violence has a detrimental effect on a victim’s physical, emotional and social life. By understanding the range of complications he or she may be experiencing, health care providers are able to offer more effective HIV/AIDS treatment. In many cases the victim, who is most often female, will not only be infected with HIV by the perpetrator, but also, due to feelings of low self-worth, socioeconomic factors or oppressive tactics, she will not be diagnosed until a later stage of the disease (39, 40). Treating PLHIV who have been subjected to violence requires the provider to do the following things (39, 41–44): • Routinely evaluate the possibility of violence for all female (and male when indicated) HIV- infected patients. • Keep the health and welfare of the patient as the first priority. “Safety first” and “do no harm” should be guiding principles. • Avoid retraumatizing the patient with questions that are likely to provoke a strong or emotional reaction, cause distress or insinuate a negative judgement. • Be prepared to respond to distress and highlight the patient’s strengths. • Be prepared to provide appropriate care, follow-up and support services (referrals). • Maintain confidentiality. 326 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION • With respect to partner notification, take into account the harm that may occur if an abuser is notified. Where such notification is mandatory, the patient should be informed about the conse- quences of disclosure prior to identifying the partner. • Agree with the person who has suffered violence upon any action that is to be taken with respect to the abuser or perpetrator. Respect the patient’s wishes, as her or his consent is essential. In accordance with legal obligations, exceptions may need to be made for suspected abuse of mi- nors. • Be prepared for emergency intervention if a patient or a patient’s dependants feel they are in imminent danger. • Provide psychological support or refer the patient to a specialist for such support, as well as for legal counselling if appropriate. • Counsel the patient on post-exposure prophylaxis (PEP) (for prevention of STIs, emergency contraception, etc.) (Please refer to Protocol 13, Post-exposure prophylaxis for HIV infection for further information.) 5. Impact of disabilities and chronic illnesses on sexual health Compared to non-disabled people, individuals with a physical, sensory, intellectual or mental health disability are often at increased risk for contracting and transmitting HIV, for substance abuse and for restricted access to services and interventions (45, 46). While PLHIV with physical disabilities and chronic illnesses contend with the same sexual health issues as their non-disabled peers, they often face additional barriers to care, such as: • difficulty accessing treatment centres due to lack of mobility or independence; • ineffective communication (lack of interpreters – including sign language – confused, compli- cated explanations, too technical language, etc.); and • homophobia, HIV stigma and the misconception among professional health providers that the physically disabled do not have sex. Disabled individuals, especially women, may also be at an increased risk for gender-based violence due to factors such as: • increased physical vulnerability • need for attendant care • social isolation • lack of economic independence • decreased access to health care • less education about safer sexual behaviours • difficulty being believed (47–49). Health care providers should ensure that PLHIV with disabilities or chronic illnesses have the same support, treatment and access to care as the non-disabled population. The range of possible mental and physical disabilities and chronic illnesses is broad, as are the specific sexual health concerns that may need to be addressed. Providers should be prepared to: • ensure patients have full access to information, care and treatment support; • address substance use; • address gender-based violence; • provid referrals to disability support organizations, substance use centres, institutions for gen- der-based violence, etc.; • determine the individual’s knowledge of and negotiation skills for safer sex; • determine the level of support available from other care providers and family members for con- traception and safer sex practices; • adapt safer sex messages for the use of the disabled; • address contraindications for ART and other drugs needed to treat a patient’s physical disability/ chronic illness; and • coordinate with other health care providers. 327 support for sexual and reproductive health in people living with hiv V. Contraception The recommendations for contraceptive methods in this section are based on a comprehensive manual of recommendations on eligibility criteria for contraceptive use (50). The manual includes HIV/AIDS as a factor in determining eligibility for each major contraceptive method. 1. Preliminary visit In addition to medical eligibility criteria, the patient’s social, cultural and behavioural context must also be considered. Contraceptive recommendations should be individualized for each woman and couple, based on disease stage and treatment as well as lifestyle and personal desires. Each woman is best placed to interpret the risks and benefits the available methods may have for her. It should be the patient who makes the final selection of contraceptive method. To make an informed choice, she requires information on: • the method’s effectiveness • its correct use • its risks and benefits • common side-effects • signs and symptoms that would necessitate a return to the clinic • cost and convenience issues • the method’s effect on transmission of STIs, including HIV. Counselling should help women living with HIV to make decisions about their fertility. It should therefore include information on: • effective contraceptive methods to prevent pregnancy and STI transmission; • the effects of HIV disease progression on health; • the effectiveness and availability of ARVs; • the services that provide ART; • the interactions between ARVs and contraceptives; • the risk of HIV transmission to an uninfected partner while trying to become pregnant; • the possible impact of HIV on pregnancy, including adverse pregnancy outcomes; • the risk of MTCT and the risks and benefits of strategies to reduce it, including ARV prophy- laxis, caesarean section and bottle-feeding;5 and • the possible birth defects associated with the use of some ARVs. 2. Medical eligibility criteria for contraceptive use by women living with HIV Most contraceptive methods are safe and effective for use by women with asymptomatic HIV in- fection as well as for women with developed HIV/AIDS disease (50). However, transmission of HIV and other STIs (HIV/STIs) warrants special consideration during family planning counselling because preventing transmission is as important as preventing pregnancy. Since condoms are the only contraceptive method shown to protect against acquiring and transmitting HIV/STIs, family planning services should strongly encourage and facilitate their consistent and correct use (51). 5 For more information, please refer to Protocol 10, Prevention of HIV transmission from HIV-infected mothers to their infants. 328 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 3. General contraceptive methods 3.1. Barrier methods and spermicides 3.1.1. Dual protection • Dual protection is defined as the simultaneous prevention of STI transmission and unwanted pregnancy. It can be achieved by the consistent use of latex condoms, either alone or in combi- nation with another method. • Dual protection is also achieved by avoidance of penetrative sex, particularly in situations of high risk. • Dual protection may be indicated to compensate for a reduction in the effectiveness of hormonal contraceptives due to interactions between ART and hormonal contraception (see section V.4.1 below). • Dual protection strategies should be part of the counselling and support provided by all repro- ductive health services (52). 3.1.2. Male latex condoms • When used consistently and correctly, male latex condoms6 protect against female-to-male, male-to-male and male-to-female transmission of HIV, as shown in studies of HIV-discordant couples7 (53). • In HIV-infected couples, condoms can offer individuals protection against new HIV strains. Limited evidence suggests that infection with more than one strain of HIV may accelerate the progression of HIV disease (54). • Laboratory studies have demonstrated the impermeability of latex condoms to infectious agents, including the smallest viruses, contained in genital secretions. • Latex condoms may be less effective in protecting against those STIs not transmitted by semen or fluid (such as herpes, human papillomavirus and syphilis), since the infected areas may not be covered by the condom (51). • Clear instructions on correct condom use are essential. To provide optimum protection against infection, they must be of good quality and be used consistently and correctly. • Emergency contraception can be offered as a backup in case a condom breaks or slips (see sec- tion V.3.6 below). • For serodiscordant couples, information and access to post-exposure prophylaxis for uninfected partners should be offered if a condom breaks or slips. • Despite the method’s efficacy, low rates of condom use have been reported, even following disclosure of positive HIV status to sexual partners (55). • Use of condoms to prevent HIV/STI transmission should be emphasized in cases where pre- vention of pregnancy is not a concern, such as pregnancy or any kind of infertility, e.g. due to sterilization or menopause. 3.1.3. Female condoms • Available data indicate that female condoms, used correctly and consistently, provide protection against STIs, including HIV (56–58). • The limited data available suggest they may be slightly less effective than male condoms for the prevention of pregnancy (59). However, they offer several advantages, including: o the possibility of insertion prior to intercourse; o no necessity for removal immediately after ejaculation; and o greater female control, though some degree of negotiation and male cooperation is still required. 6 Condoms made of animal membranes do not protect against HIV, as such when the term condom is used in this document, it refers to latex condoms unless otherwise stated. 7 Couples with discordant serostatus – those in which one sexual partner is HIV-positive and the other HIV-negative – may require special support. Protected sex using a condom is the only way to ensure PLHIV that HIV-negative sexual partners can remain uninfected. 329 support for sexual and reproductive health in people living with hiv 3.1.4. Other barrier methods (diaphragms, cervical caps) Women for whom pregnancy is an unacceptable risk should be advised that other contraceptive barrier methods (diaphragms and cervical caps) may not be appropriate because of their relatively higher typical-use failure rates for those who cannot use them consistently and correctly. It should also be stressed that they do not protect against the transmission of HIV or other STIs. 3.1.5. Spermicides • Since nonoxynol-9 may cause some side-effects, condoms lubricated with it should no longer be promoted; nevertheless, it is better to use a nonoxynol-9-lubricated condom than no condom (60). • The safety concerns with nonoxynol-9 also apply to other spermicidal products marketed for contraception. Spermicides should not to be used by women living with HIV, neither alone or with other barrier methods such as diaphragms or cervical caps. • There is no evidence that nonoxynol-9-lubricated condoms provide any more protection against pregnancy or sexually transmitted infections than condoms lubricated with silicone. 3.2. Low-dose combined oral contraceptives (COC) Table 7. low-dose coc (≤35 μg of ethinylestradiol (ee)) for women living with hiv Status Categorya Comment High risk of HIV 1 Overall, evidence is inconsistent regarding whether there is any increased risk of HIV acquisition among COC users. HIV/AIDS without ART 1 Limited evidence suggests no association between COC use and changes in RNA levels or CD4 counts among HIV-infected women. There is also limited evidence showing no association between COC use and female-to-male HIV transmission, and mixed results regarding increased risk of HIV and HSV shedding among HIV-infected women using hormonal contraception. HIV/AIDS + ART 2 For women on ART, refer to the section on drug interactions below (V.4.1). As there may be drug interactions between hormonal contraceptives and ARVs, such use is clas- sified as Category 2. Drug interactions ARVs 2 It is important to note that ARV drugs have the potential to decrease or increase the bioavailability of steroid hormones in hormonal contraceptives. The limited data avail- able suggest that interactions between many ARVs (particularly some NNRTIs and PIs) and hormonal contraceptives may alter the safety and effectiveness of both. For women initiating or continuing hormonal contraceptive use while on ART, the consistent use of condoms is recommended for preventing HIV transmission; it may also compensate for any possible reduction in the effectiveness of the hormonal contraceptive. See section V.4 below. a Category 1: no restrictions for use of contraceptive method; use in any circumstances. Category 2: advantages of using method generally outweigh theoretical or proven risks. Generally advisable to use the method. Note: COCs do not protect against HIV/STIs. If there is risk of HIV/STIs, the correct and consistent use of condoms is recom- mended, either alone or with another contraceptive method. Male latex condoms are proven to protect against HIV/STIs. Source: WHO (50). There are concerns that women may have a greater risk of acquiring STIs when using hormonal contraceptives, possibly due to decreased condom usage. Yet the evidence is inconsistent regarding whether hormonal contraceptive users have greater risk of acquiring HIV than non-users (50). 330 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 3.3. Progestogen-only contraceptives (POCs) Progestogen-only contraceptives include progestogen-only pills (POPs), injectable progestogens (depot medroxyprogesterone acetate (DMPA) and norethisterone-enantate (NET-EN)) and proges- togen implants (levonorgestrel implants (Norplant and Jadelle) and etonogestrel implants (Impla- non)) (see Table 8). Table 8. progestogen-only contraceptives for women living with hiv Condition Categorya Comment POP D/NE LN/ETG High risk of HIV 1 1 1 Overall, evidence is inconsistent as to any increased risk of HIV acquisition among POC users. HIV/ AIDS with- out ART 1 1 1 Studies conflict over whether there is increased risk of HIV and HSV shedding among HIV-infected women using DMPA. HIV/AIDS + ART 2 2 2 For women on ART, refer to the section on drug interactions (V.4.1 below). As there may be interactions between hormonal contracep- tives and ARVs, it is classified as Category 2. Drug interactions ARV 2 2 2 ARVs have the potential to decrease or increase the bioavailabil- ity of steroid hormones in hormonal contraceptives (see section V.4.1 below). It is not known whether the contraceptive effective- ness of injectable POCs (such as DMPA and NET-EN) would be compromised, as they provide higher blood hormone levels than other POCs and COCs. Studies are underway to evaluate potential interactions between DMPA and selected PI and NNRTI drugs. For women initiating or continuing hormonal contraceptive use while on ART, the consistent use of condoms is recommended for pre- venting HIV transmission; it may also compensate for any possible reduction in the effectiveness of the hormonal contraceptive. D/NE: depot medroxyprogesterone acetate (DMPA)/norethisterone enantate (NET-EN); LNG/ETG: levonorgestrel implants (Norplant and Jadelle) and etonogestrel implants (Implanon); POP: progestogen-only pill. a Category 1: no restrictions for use of contraceptive method; use in any circumstances. Category 2: advantages of using method generally outweigh theoretical or proven risks. Generally advisable to use the method. Note: POCs do not protect against HIV/STIs, though neither has the use of POCs been associated with HIV acquisition or transmission (61). If there is risk of HIV/STIs, the correct and consistent use of condoms is recommended, either alone or with another contraceptive method. Male latex condoms are proven to protect against HIV/STIs. Source: WHO (50). 3.4. Combined contraceptives in injectable, patch and ring form For women living with HIV, there are no restrictions on the use of combined injectable contracep- tives (CICs), combined contraceptive patches or combined contraceptive vaginal rings. • CICs provide for the release of a natural estrogen plus a progestogen. Two CIC formulations, both given at four-week intervals, are considered here: Cyclofem (medroxyprogesterone acetate 25 mg plus estradiol cypionate 5 mg) and Mesigyna (norethisterone enantate 50 mg plus estra- diol valerate 5 mg). • The combined contraceptive patch is a 20 cm2, three-layer patch applied to the buttocks, torso, abdomen or upper arm to release ethinylestradiol and a progestogen (norelgestromin) transder- mally. The combined contraceptive patch currently available is Evra (17-deacetyl norgestimate (norelgestromin) 150 µg plus ethinylestradiol 20 µg). A new patch has to be applied once a week for three consecutive weeks each month. • The combined contraceptive vaginal ring releases ethinylestradiol and a progestogen (etono- gestrel) from a 54 mm ethylene vinyl acetate copolymer ring. The vaginal ring formulation currently available is NuvaRing (etonogestrel 120 µg plus ethinylestradiol 15 µg). It is inserted once a month, taken out after 21 days to allow the normal menstrual cycle, and a new ring is inserted after a 7-day break. 331 support for sexual and reproductive health in people living with hiv The contraceptive effect of CICs, patches and vaginal rings is achieved by inhibiting ovulation. These contraceptive methods are new, with little epidemiological data on their long-term effects (see Table 9). Table 9. cics and combined contraceptive patches and rings for women living with hiv Status Categorya Comment CIC Patch Ring High risk of HIV 1 1 1 — HIV/AIDS without ART 1 1 1 Relatively limited information is available on the safety of the combined contraceptive patch and vaginal ring.

HIV/AIDS + ART 2 2 2 For women on ART, refer to the section on drug interactions (V.4.1 below). As there may be interactions between hormonal contraceptives and ARVs, this use is classified as Category 2. Drug interactions ARVs 2 2 2 ARVs have the potential to decrease or increase the bioavailability of steroid hormones in hormonal contraceptives (see section V.4.1 below).

For women initiating or continuing hormonal contraceptive use while on ART, the consistent use of condoms is recommended for preventing HIV transmission; it may also compensate for any possible reduction in the effectiveness of the hormonal contraceptive. a Category 1: no restrictions for use of contraceptive method; use in any circumstances. Category 2: advantages of using method generally outweigh theoretical or proven risks. Generally advisable to use the method. Note: CICs, patches and rings do not protect against HIV/STIs. If there is risk of HIV/STIs, the correct and consistent use of condoms is recommended, either alone or with another contraceptive method. Male latex condoms are proven to protect against HIV/STIs. Source: WHO (50). 3.5. Intrauterine devices (IUDs) IUDs can be safely used by women living with HIV, whether asymptomatic, on ART or clinically well, but such users should be closely monitored for pelvic inflammatory disease (PID). IUDs are not usually recommended for women living with AIDS who are not on ART if more appropriate contraceptive methods like condoms or steroid hormonal contraceptives are available and accept- able. While physicians should be wary of over-diagnosing PID, it is highly probable with IUD-wearers when one or more of the following symptoms are observed: • lower genital tract infection • cervical motion tenderness • adnexal tenderness • enlargement of one or both Fallopian tubes, a tender pelvic mass • direct or rebound tenderness • elevation of temperature (temperature may be normal in many cases of PID). Hospitalization of patients with acute PID should be seriously considered when: • the diagnosis is uncertain • surgical emergencies such as appendicitis and ectopic pregnancy cannot be excluded • a pelvic abscess is suspected • severe illness precludes management on an outpatient basis • the patient is pregnant • the patient is unable to follow or tolerate an outpatient regimen • the patient has failed to respond to outpatient treatment. 332 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION The levonorgestrel-releasing intrauterine device (LNG-IUD) releases 20 µg of levonorgestrel (LNG) daily, directly into the uterus. Because LNG suppresses endometrial growth, users can expect a marked reduction in the amount of menstrual blood. Many women experience little or no bleeding (amenorrhea) within a year of beginning use. In sexual relations where the recommended condoms are not used, a reduction of menstrual blood loss may be regarded as a means of decreasing the risk of female-to-male HIV transmission (see Table 10). Table 10. iuds for women living with hiv Condition Categorya (I: initiation, C: continuation) Comment Cu-IUD LNG-IUD I C I C High risk of HIV 2 2 2 2 Among women at risk of HIV, copper-releasing IUD (CU-IUD) use did not increase risk of HIV acquisition. HIV/AIDS with- out ART 2 2 2 2 Limited evidence shows no increased risk of overall or infection- related complications among IUD users when comparing HIV- infected women with non-infected women. Furthermore, it shows no association between IUD use among HIV-infected women and increased risk of transmission to sexual partners. IUD users with AIDS should be closely monitored for PID.

However, IUD use by AIDS patients is classified as Category 3 for insertion and Category 2 for continuation, unless the woman is clinically well on ART, in which case both insertion and con- tinuation are classified as Category 2. Cu-IUD = copper-releasing IUD; LNG-IUD = levonorgestrel-releasing IUD (20 µg/24 hours), a Category 1: no restrictions for use of contraceptive method; use in any circumstances. Category 2: advantages of using method generally outweigh theoretical or proven risks. Generally advisable to use the method. Category 3: method not usually recom- mended unless other more appropriate methods are not available or not acceptable (theoretical or proven risks usually outweigh the advantages of using the method). Note: IUDs do not protect against HIV/STIs. If there is risk of HIV/STIs, the correct and consistent use of condoms is recom- mended, either alone or with another contraceptive method. Male latex condoms are proven to protect against HIV/STIs. Source: WHO (50). 3.6. Emergency contraception Emergency contraception can prevent pregnancy when: • a contraceptive method fails • no method was used • sex was forced. Emergency contraceptive pills inhibit or delay ovulation, and prevent implantation and fertilization or transport of sperm/ova by altering the endometrium. When used within 72 hours after sex: • the Yuzpe regimen (COC) prevents about 74% of expected pregnancies (62); • POPs prevent 85% of expected pregnancies under typical use and 89% under correct use (63); and • POPs produce fewer side-effects than COCs. 333 support for sexual and reproductive health in people living with hiv 3.6.1. Emergency contraceptive pill regimens • One of the best-studied progestogen-only regimes consists of 1.5 mg of levonorgestrel (two pills containing 0.75 mg taken either in a single dose or at a 12-hour interval). Ideally, the pills should be taken within 72 hours of unprotected intercourse. • If low-dose pills containing 30 µg ethinylestradiol and 150 µg levonorgestrel are used, four pills should be taken in a first dose as soon as convenient, but no later than 72 hours after unprotected intercourse. These should be followed by a second dose of four pills 12 hours later. • The standard regimen (the Yuzpe method) consists of the combined oral pills containing 50 µg ethinylestradiol and 250 µg levonorgestrel. Two pills should be taken in a first dose as soon as convenient, but no later than 72 hours after unprotected intercourse. These should be followed by a second dose of the same pills 12 hours later. The most common side-effects of hormonal emergency contraception are nausea and vomiting. The Yuzpe regimen is associated with a 42% incidence of nausea and a 16% incidence of vomiting (64). These problems were significantly less common among users of the levonorgestrel regimen, at 23% and 6%, respectively (63). The Yuzpe regimen can be used if levonorgestrel or mifepristone are not available. Several observations should be made about the management of side-effects: • Taking the pills with food or at bedtime may help reduce nausea. • If vomiting occurs within two hours of taking the pills, the dose should be repeated. In cases of severe vomiting, the repeat dose may be administered vaginally. • The majority of women will have their menstrual period on time or slightly early. If there is a delay of more than one week, a pregnancy test should be performed. • A single dose simplifies the use of levonorgestrel for emergency contraception without increas- ing side-effects. • Breast tenderness, headache, dizziness and fatigue may occur. Hormonal emergency contraception may have side-effects in women living with HIV. • There are no studies of side-effects in women living with HIV, neither on ART or off. Nausea and vomiting are side-effects with some ARTs and may be intensified when taking emergency contraceptive pill regimens. • The Yuzpe regimen should be avoided in women taking indinavir, atanazavir, amprenavir or efavirenz since it raises estradiol levels, which may increase the risk of thrombo-embolic dis- ease (see section V.4.1 below). 3.6.2. IUDs as emergency contraceptives • A copper-releasing IUD can also be used within five days of unprotected intercourse as an emer- gency contraceptive. • When the time of ovulation can be estimated, the Cu-IUD may be inserted more than five days after intercourse if necessary, as long as the insertion does not also occur more than five days after the earliest estimated ovulation. 3.6.3. Mifepristone • Orally administered mifepristone (10 mg), an antiprogestin, offers high efficacy with few side- effects when taken within 120 hours (five days) of unprotected intercourse (65). • Mifepristone can delay menstruation, which may in turn increase patient anxiety. • There are no studies about the efficacy or side-effects of mifepristone in women living with HIV, either with or without ART. 334 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 3.7. Surgical sterilization procedures Given that sterilization is a surgical procedure intended to be permanent, special care must be taken to ensure that every patient who chooses it is making a voluntary informed choice. All patients, irrespective of HIV status, must understand the permanence of sterilization and be informed of al- ternative contraceptive methods. The indications and contraindications for sterilization are the same as for HIV-negative patients. As sterilization provides no protection against STI acquisition or HIV transmission, it is essential to stress the importance of condom use, particularly as sterilization has been associated with a de- crease in condom use. The national laws and existing norms for sterilization procedures must also be considered in the decision process. The general health of any PLHIV who opt for this procedure must be examined carefully before any elective surgery is undertaken. A decision to proceed depends on any existing AIDS-related ill- nesses that may compromise the patient. 3.8. Fertility-awareness methods and coitus interruptus Fertility-awareness methods and coitus interruptus are characterized by higher typical-use failure rates than other methods and should not be routinely recommended for either HIV-positive or -neg- ative women. 3.9. Lactational amenorrhea method This method is not recommended due to the need to avoid HIV transmission in serodiscordant couples and breastfeeding infants. Replacement feeding is recommended where acceptable, fea- sible, affordable, sustainable and safe. Otherwise, exclusive breastfeeding is recommended during the first months of life and should then be discontinued as soon as feasible. Mothers living with HIV should be helped to make the best choice for feeding their infants in accor- dance with their circumstances, and to carry out their decision. They should thus receive counsel- ling that includes information about the risks and benefits of various infant feeding options (based on local assessments), and support to carry out their choice safely and appropriately. 3.10. Future prospects Developmental work on microbicides, which could provide an invaluable method of dual protec- tion, is underway. Such products are inserted into the vagina before sexual intercourse to prevent transmission of HIV/STIs and would be thus under the control of the woman. Although some mi- crobicides aim to provide dual protection against unintended pregnancies and HIV/STIs, others are only intended to prevent the latter. So far, no microbicides have been shown to decrease MTCT effectively, nor are any microbicidal products on the market for the prevention of sexual transmis- sion of HIV or other STIs. Until effectiveness trials demonstrate safety and efficacy, microbicide use should not be promoted. 335 support for sexual and reproductive health in people living with hiv 4. Contraception for women on ARV WHO recommends using highly active antiretroviral treatment (HAART) for PLHIV who are eli- gible for ART in accordance with the WHO clinical staging system (for more information please see Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents). ARV regimens recommended by the WHO Regional Office for Europe for first- and second-line therapy are shown in Table 11. Table 11. recommended first- and second-line haart regimens for adults and adolescents First-line regimens Second-line regimens ZDV + 3TCa + EFVb or NVP LPV/rc + ddI + ABC LPV/rc + TDF + ABC LPV/rc + TDF + (ZDV + 3TC)d TDF + FTCa + EFV or NVP LPV/rc + ddI + ABC LPV/rc + ddI + ZDV ABC + 3TCa + EFV or NVP LPV/rc + ddI + ZDV LPV/rc + (ZDV + 3TC)d a 3TC (lamivudine) and FTC are considered interchangeable agents, given their activity, tolerance and resistance profiles. They are both listed in this table as a reflection of the commonly available FDCs. b For the purpose of this table, treatment failure on an NVP- or EFV (efavirenz)-based regimen is considered to result in NNRTI class cross-resistance. c LPV/r is listed as the preferred RTV-boosted protease inhibitor (PI) in this table, but other boosted PIs can be substituted based on individual programme priorities. ATV/r, SQV/r, FPV/r and IDV/r are all possibilities. In the absence of a cold chain, NFV can be employed as the PI component, but it is considered less potent than a boosted PI. d ZDV + 3TC is listed here for “strategic” use, as resistance to both drugs is predicted to be present following failure on the respective first-line regimen listed. ZDV may prevent or delay the emergence of the K65R mutation; 3TC will maintain the M184V mutation, which may decrease viral replicative capacity as well as induce some degree of viral resensitization to ZDV. It must be stressed that the clinical efficacy of this strategy in this situation has not been proven. 4.1. Interactions between ARVs and steroids in hormonal contraceptives The limited data available suggest that several ARVs, especially NNRTIs and PIs, have the potential to either decrease or increase the bioavailability of steroid hormones in hormonal contraceptives. These drug interactions may alter the safety and effectiveness of both the hormonal contraceptives and the ARVs. The possible interactions betweem ARVs and COCs, as well as the suggested alter- natives, should be taken into consideration and discussed with the patients. 336 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Table 12 summarizes the most recent evidence regarding ARVs and steroids in COCs and provides management recommendations regarding use of the latter (66). Table 12. interactions between arvs and ethinylestradiol (ee)/norethindrone (ne) acetate ARVs Effect of coadministration on EE, NE acetate and ARV levels Recommendations Protease inhibitors (PIs) Atazanavir (ATV) EE ↑ 48%, NE ↑ 110% Use the lowest effective dose or an alterna- tive method. Fosamprenavir (FPV) EE and NE ↑, FPV↓20% Do not coadminister, alternative contracep- tive methods recommended. Indinavir (IDV) EE ↑24%, NE ↑26% No dose adjustment required. Lopinavir/ritonavir (LPV/r) EE ↓ 42% Use an alternative or additional method. Nelfinavir (NFV) EE ↓ 47%, NE ↓18% Use an alternative or additional method. Ritonavir (RTV) EE ↓ 40% Use an alternative or additional method. Saquinavir (SQV) No data — Non-nucleoside reverse transcriptase inhibitors (NNRTIs) Efavirenz (EFV) EE ↑ 37% Use an alternative or additional method. Nevirapine (NVP) EE ↓ 20% Use alternative contraceptive methods. No data are available for interactions between ARVs and levonorgestrel. It is not known whether the contraceptive effectiveness of progestogen-only injectable contraceptives (such as DMPA and NET-EN) would be compromised – these methods provide higher blood hormone levels than other progestogen-only contraceptives or combined oral contraceptives. 4.2. Interactions between ARVs and IUDs There are no known interactions between ARVs and either the copper- or the levonorgestrel-releas- ing IUDs. 4.3. Teratogenicity of EFV • EFV is considered potentially teratogenic and should be avoided for women trying to conceive or not using effective contraception. • It is recommended that women have a pregnancy test prior to initiating treatment with EFV. • For women using effective contraception, EFV is a viable option for the NNRTI component of an ARV treatment regimen. 4.4. Adherence to contraception and HIV/AIDS treatment HIV-positive women may need to take several pills each day for ART, prophylaxis or treatment of opportunistic infections, symptomatic relief or treatment of concurrent illnesses. In addition to potential drug interactions, the impact of pill burden on adherence to contraception and HIV-related therapies should be considered. A hormonal contraceptive method that requires daily administra- tion will increase pill burden. Women need to be aware of these considerations when they select a contraceptive method. 5. Contraceptive methods for women on both ART and TB treatment • For women receiving ART and tuberculosis (TB) treatment, drug interactions with certain hor- monal contraceptives can reduce the effectiveness of hormonal contraception. • Due to drug interactions, a non-hormonal method of contraception is preferable for women re- ceiving both ART and TB treatment. 337 support for sexual and reproductive health in people living with hiv • If hormonal contraception is the only option, low-dose (<35 µg) estrogen COC is usually not recommended for women receiving rifampicin. Although evidence is limited, use of an oral contraceptive pill containing a higher dose of estrogen (50 µg) may be considered unless the patient is taking EFV, IDV, APV or ATV. • DMPA can generally be used with rifampicin. • The effectiveness of LNG-IUDs is unlikely to be reduced. 6. Considerations for the most vulnerable populations Sexual and reproductive health services should strive to create a supportive and non-discrimina- tory environment for specific vulnerable populations. Due to the stigma attached to these popula- tions, they often do not seek health care through conventional channels. It is therefore important for outreach to be part of the strategy for all SRH programmes in order to improve access for these groups. 6.1. Sex workers (male and female) • Consistent condom use should be recommended to sex workers for use with clients and their regular partners to prevent HIV transmission to the uninfected partner. • Pending evidence on the reuse of female condoms, it is recommended that they be used only once. 6.2. MSM • MSM should be advised to use water-based or silicone-based lubricants during anal sex to main- tain condom integrity. 6.3. IDUs • Drug-related amenorrhea is not an indication of infertility. It is thus important to advise women who are injecting drug users on regular use of contraception to prevent unintended pregnancy. • Links should be reinforced between RH and harm reduction (HR) services. 7. Recommendations for contraceptive methods • Discussion of family planning should be initiated during post-test HIV counselling and contin- ued in follow-up sessions and at regular intervals throughout care. • All staff should understand that they have a professional responsibility to maintain HIV confi- dentiality. • In addition to medical eligibility criteria, the social, cultural and behavioural context should also be considered, and recommendations for contraceptive methods should be tailored to the individual, based on disease stage, treatment, lifestyle and personal wishes. • Transmission of HIV and other STIs warrants special consideration during family planning counselling. Family planning services should strongly encourage and facilitate the consistent and correct use of condoms as the only contraceptive method that protects against HIV and other STIs. Furthermore, all reproductive health services should provide support for dual pro- tection. • Links between harm-reduction services for IDUs and HIV/AIDS treatment and care services should be established and strengthened to provide better continuity of care. 338 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION VI. Safe abortion Preventing unintended pregnancies and unsafe abortions is essential for improving the reproductive health of all women, including those living with HIV. Even where contraceptive services are avail- able, unintended pregnancies still happen for a variety of reasons – contraceptives may fail, male partners may oppose using condoms or other forms of contraception, people may not use contracep- tives for fear of side-effects, unprotected sex may be coerced or forced, etc. – and many women will seek termination of these pregnancies. In case HIV infection is diagnosed during pregnancy, the woman may seek termination of preg- nancy even if the pregnancy was planned or wanted. For whatever reason women living with HIV want to terminate a pregnancy, they should have access to safe abortion. When induced abortion is performed by qualified people using correct techniques in sanitary condi- tions, it is a safe procedure. Restrictive abortion legislation is associated with a high incidence of unsafe abortion, performed by unskilled providers and/or in unhygienic conditions. On the other hand, abortion should not be presented as a method of family planning. Every woman has the right to – and should have the opportunity to make – informed choice regarding her pregnancy and should not be coerced, either into terminating the pregnancy or carrying it to term. 1. Abortion counselling If a woman’s HIV status is unknown, HIV testing and counselling should be offered during counsel- ling on unwanted pregnancy; however, a HIV test should not be mandatory, and refusal to be tested should not affect her access to safe abortion services. Neither should HIV testing be requested in order to protect staff, as universal infection control precautions should be taken for every abortion. Non-directive, non-judgemental, confidential counselling should be provided by a professional trained in pregnancy termination and well informed on the subject of HIV infection in pregnan- cy. Complete and accurate information, given respectfully in understandable language, will assist women in making the best decisions about their pregnancies. In cases of minors or people mentally incapable of informed consent, assistance should be provided according to national regulations. If drug use is involved, additional expertise may be required. If sexual intercourse between an HIV-negative woman and an HIV-positive man results in preg- nancy, HIV infection is unlikely to have occurred in the woman if the HIV antibody screening test is negative one month after exposure and can be excluded if negative six months after exposure. If an early diagnosis is needed, HIV infection should be highly suspected if there is: • a positive detection of HIV RNA, starting 15 days post-exposure; • p24 antigenaemia, starting 18 days post-exposure; or • a positive HIV-antibody screening test, starting three weeks post-exposure (subject to confirma- tion and expert advice). Counselling for HIV-infected women should include: • the risks of pregnancy to her own health • the risks of transmission to the newborn • the effectiveness of ARVs and other interventions in reducing MTCT • the potential side-effects of such interventions, including ARV toxicity. 339 support for sexual and reproductive health in people living with hiv 2. Surgical and medical methods of abortion Abortion methods used for women living with HIV do not differ from those used for HIV-negative women. Both surgical and medical methods of abortion are safe. See Fig. 1 for the recommended methods at various stages of gestation. Figure 1 Methods of abortion Completed weeks since last menstrual period 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 Preferred methods Vacuum aspiration (manual/electric) (by specifically trained providers) Dilatation and evacuation Mifepristone and miso- prostol (or gemeprost) (under investigation) Mifepristone and repeated doses of misoprostol or gemeprost Vaginal prostaglandins (repeated doses) Other methods Dilatation and curettage Hypertonic solutions Intra/extra-amniotic prostaglandins Source: WHO (67). • The complication rate is low for abortions that meet international standards (67). • Haemoglobin should be measured and anaemia treatment initiated in accordance with etiology. • The presence of infection in the lower reproductive tract at the time of abortion is a risk factor for post-procedural RTIs. • The routine use of antibiotics at the time of abortion has been reported to reduce the post-pro- cedural risk of infection by half. However, safe abortion can still be performed when antibiotics are not available for prophylactic use (67). • There is currently no data available about the effectiveness of the recommended dosages of mifepristone, misoprostole and gemeprost in women living with HIV, so the recommended dosages of these drugs for medical abortion (67) does not differ from those for HIV-negative women. • There are currently no data available about potential interactions between mifepristone, miso- prostole and ARVs in HIV-positive women. 340 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 3. Post-abortion care and family planning Ensuring confidentiality is a key issue in post-abortion care. Post-abortion care for HIV-infected women should include: • evaluation and treatment of any complications; • minimizing transmission of HIV and other STIs in the post-abortion period, including from uterine bleeding; • family planning counselling and services; and • referrals for continuing HIV/AIDS treatment, care and support. In settings where HIV and/or abortion are stigmatized, women living with HIV may need additional counselling and psychosocial support. Otherwise, post-abortion and family planning counselling should be the same, regardless of HIV status. Most contraceptive methods can be started immediately post-abortion. 4. Recommendations • Non-directive, non-judgemental, unbiased and confidential counselling about termination of pregnancy should be provided by a trained person (to the extent allowed by law). • In countries where abortion is not against the law, safe termination of pregnancy should be available and accessible to women living with HIV. • Family planning counselling and services should be essential components of post-abortion care, as they assist women in avoiding unintended pregnancies and reducing repeat abortions. 341 support for sexual and reproductive health in people living with hiv VII. Natural or medically assisted reproduction Most PLHIV are of childbearing age and may desire to have children. They should have access to the same SRH counselling and services as other people. Nor is there, in cases of couple infertility, any reason to exclude couples with HIV from accessing reproduction technology. 1. Reproductive counselling for couples with HIV The aims of reproductive counselling for couples with HIV include: • reducing the risk of transmission to both the uninfected partner in HIV serodiscordant couples and their offspring; • enabling informed reproductive choices; • informing couples about the risks of HIV transmission and chances of pregnancy in both natural and medically assisted conception; • preparing couples for the psychological impact of assisted conception, addressing the issues of: o availability o duration of treatment o failure o logistics; • discussing the possibility of foster or adoptive parenting where available to couples with HIV; and • informing and advising couples about hepatitis B (HBV) and C (HCV), including the risks of sexual transmission (HBV) and vertical transmission (HBV and HCV). 2. Fertility 2.1. Women • Most women living with HIV menstruate about every 25–35 days, suggesting monthly ovula- tion (68). • So far, the impact of ART on fertility has not been explored in women living with HIV. • Drugs, including methadone and psychotherapeutic medications, may contribute to menstrual disorders in women living with HIV (69). • HIV may not affect a woman’s reproductive potential, unless she is highly immunosuppressed and presents with opportunistic infection. Nevertheless, fertility is lower in HIV-infected wom- en than in the general population (70). 2.2. Men • HIV can be identified in the semen of men living with HIV regardless of the viral load in the blood. • Many men living with HIV have normal semen analyses for fertility (71). • Healthy men living with HIV have semen fertility analyses similar to those of HIV-negative men, while AIDS patients have grossly abnormal semen (72). • Some ARV drugs may have an effect on spermatogenesis (73). • Men infected with HIV may experience sexual dysfunction including erectile dysfunction. 3. Pregnancy duration and outcome • Women living with HIV have a greater risk of certain adverse pregnancy outcomes (intrauterine growth retardation, pre-term delivery, low-birth-weight infants, etc.) than HIV-negative women (74). 342 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION • Although data are limited, several studies have suggested there is an increased risk of spontane- ous abortion and stillbirth among women living with HIV (74). • The effects of HIV infection on pregnancy outcomes are likely to be more pronounced among women with symptomatic HIV infection (75). • Pregnancy does not have an effect on HIV disease progression or mortality (76, 77). • The risk of opportunistic infections among women with HIV does not appear to be altered by pregnancy. 4. Counselling before conception Assisting people living with HIV in decisions about childbearing requires counselling on: • the risk of HIV transmission to the partner, and interventions that can reduce it (see the next section); • effects of HIV on pregnancy, including increased risk of certain adverse outcomes; • the safety of ARVs during pregnancy, and their possible side-effects; • the risk of birth defects while receiving particular ARVs; and • the effectiveness of ARV prophylaxis, caesarean section and bottle-only feeding in reducing the risk of MTCT. 5. Reducing the risk for sexual transmission of HIV during conception Special support should be considered for couples with discordant serostatus wishing to conceive: • They need reproductive counselling and assistance to limit the risk of HIV transmission to the uninfected partner in unprotected sexual intercourse. • Even though some serodiscordant couples have started pregnancies through timed unprotected intercourse without infecting the negative partner, this practice is unsafe and is not recom- mended. • Specific methods of sperm preparation and testing can substantially reduce the chance of HIV transmission to the female partner (78, 79). Male-positive discordant couples who want to have a child should be informed of risk-reduction techniques and encouraged to seek assistance at institutions that can provide the most effective methods of sperm preparation. 5.1. Sperm-washing and virological determination of HIV in semen Sperm washing can be carried out in any laboratory providing assisted reproduction services to infertile couples. It is a three-step semen processing method consisting of: 1. gradient centrifugation to isolate motile spermatozoa and reduce the number of potentially in- fected non-spermatozoa cells; 2. repeated washing of the cell preparation to eliminate cell-free virus; and 3. spontaneous migration to obtain an aliquot of motile virus-free spermatozoa (80, 81). It is recommended that all processed samples be tested for HIV prior to insemination using poly- merase chain reaction techniques (82). HIV genome detection in semen requires special technical equipment and skills. The use of universal infection control procedures and specific training should be provided to laboratory staff to avoid HIV infection when handling potentially infectious semen. 6. Assisted reproductive technology in case of HIV infection Fertility screening and STI diagnosis and treatment of both partners are needed before assisted re- productive technology can be considered. A history of fertility, HIV-related parameters (including CD4 count and viral load) and ART should be established. 343 support for sexual and reproductive health in people living with hiv Basic fertility assessment includes a clinical evaluation of ovulation, hormonal parameters (follicle- stimulating hormone (FSH), luteinizing hormone (LH) and prolactin) and tubal patency for women and a sperm analysis (count, motility, progression and morphology) for men. 6.1. Fertile couples In serodiscordant fertile couples with an HIV-positive woman, the use of artificial insemination should be encouraged. Home artificial insemination – introducing sperm collected in a condom into the vagina after intercourse using a simple syringe or other clean receptacle, after advice on recog- nizing and identifying the fertile period – can provide a means of conception that prevents the male partner from becoming infected. A number of serodiscordant couples with HIV-positive men wish to have children. There is no risk- free method for ensuring safe conception in this situation. However, the use of sperm-washing (see section VII.5.1 above) to reduce levels of HIV in semen has allowed many men living with HIV to father seronegative children (83). In fact, with washed sperm of undetectable viral load, there is minimal risk of transmission of HIV to the female partner and children (84). If both the man and woman are HIV-positive, sperm washing can also be used to limit the woman’s risk of HIV superinfection. 6.2. Infertile couples After one year of repeated attempts at home artificial insemination without pregnancy, couples may be referred to infertility counselling and treatment. Artificial insemination and assisted reproductive technology are available in some places. Foster or adoptive parenting should also be considered. For issues related to pregnancy in HIV-infected people and prevention of MTCT, please refer to Protocol 10, Prevention of HIV transmission from HIV-infected mothers to their infants. 344 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION VIII. Cervical intraepithelial lesions and cervical cancer Cervical cancer is one of the most common types of cancer, causing deaths among women world- wide. The estimated number of new cases per year is 500 000 (85). Human papillomavirus infection with oncogenic genotypes is the etiologic agent in the development of premalignant and malignant lower genital tract disease, including cervical cancer. The development of cancer from precursor lesions is a long process and may take up to 20 years, a process that has been the basis for the devel- opment of cytological screening programmes to detect pre-invasive disease (see Annex 5) (86). The relative risk for cervical intraepithelial neoplasia (CIN) is 5–10 times higher for women living with HIV than for other women (87, 88). 1. Initial and follow-up evaluation • Women should have a complete gynaecological examination, including a Pap test and pelvic examination, as part of their initial HIV evaluation. • HIV-positive women are more likely to have genital warts and squamous intraepithelial neopla- sia of the external genitalia than those who are HIV-negative (89); careful physical examination of the external genitalia of women living with HIV is crucial. • Cytology screening is effective in women living with HIV. • Cervical cancer screening should be offered to women living with HIV at least once a year, us- ing the same test offered to uninfected women (see Annexes 5–7). • If an HIV-positive woman has been treated for precancerous lesions, she should have Pap smears every 4–6 months until at least three negative results have been be obtained (89). • A high-risk HPV deoxyribonucleic acid (DNA) detection test can be performed in case of a Pap smear with either atypical squamous cells of undetermined significance (ASC-US) or atypical squamous cells where a high-grade squamous intraepithelial lesion (HSIL) cannot be ruled out (ASC-H) (89). • Examination of the entire lower genital tract, including vagina, vulvae and perianal areas, col- poscopy and biopsy of cervix, to confirm cytological and visual abnormalities is recommended in case of: o abnormal cytology (persistent low-grade squamous intraepithelial lesions (LSILs), ASC-US or HSILs); o an oncogenic HPV type; or o a history of untreated abnormal Pap smear (89). 2. General management of patients with CIN The general management of CIN among women living with HIV should not differ from that for the general population. Despite a modest effect of ART on spontaneous regression of CIN, follow-up of women on ART should be the same as follow-up of women not receiving ART. Observation without specific intervention is recommended for biopsy-proven CIN 1 unless one of the following condition obtains: • lesions persist over an 18–24 month period • lesions evolve to CIN 2 or worse • there is poor adherence to routine monitoring (89, 90). 345 support for sexual and reproductive health in people living with hiv 3. Treatment of cervical intraepithelial lesions • HIV-infected women should be counselled before pre-cancer treatment to ensure that they un- derstand the need for close follow-up and the possibility for repeated treatments. • Cone biopsy can be done under local anaesthesia on an outpatient basis using a cold knife tech- nique or a loop electrosurgical excision procedure (LEEP). • CIN 2 and 3 require excisional or ablative treatment. • Women living with HIV have a high rate of recurrence/persistence (40–60%) and progression of CIN 2 and 3 after treatment, and should therefore be monitored every six months after treat- ment. Prompt re-treatment should be provided when persistent, recurrent or progressive high- grade lesions are detected (90). • Hysterectomy is contraindicated as a pre-cancer treatment in the absence of other indications (90). • Treatment for CIN should not be modified for patients receiving ART. • ART should not be instituted or modified for the purpose of treating CIN. • Abstinence from sexual intercourse is recommended following treatment; if this is not possible, condoms should be used consistently and correctly. 4. Management of invasive cancer • The International Federation of Gynecology and Obstetrics (FIGO) classification system is rec- ommended for determining the cancer stage (91). • For women with a CD4 count <200 cells/mm3, surgery is the preferred option when appropriate, or attenuated treatment with radiation or chemotherapy (90). • Women with advanced HIV disease have a poor prognosis with all treatment modalities. For women with a CD4 count >200 cells/mm3, standard treatment modalities may be used. • Comprehensive palliative care programmes are essential for improving the quality of life for women with cervical cancer (see Protocol 3, Palliative care for people living with HIV). 5. Anal screening There is no medical consensus about the use of anal Pap smear screening at this time. 346 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION IX. Suggested minimum data to be collected at the clinical level The suggested minimum data to be collected are important in the development of key indicators on access to services and their success. Such indicators assist managers in decision- making on ways to strengthen and expand these services to all who need them. The following data should be collected at the clinical level on a regular basis (e.g. monthly, quar- terly or semi-annually): • number of HIV-infected women of reproductive age having sexual intercourse during the last six months; • number of HIV-infected women (cumulative) using modern contraceptive methods; • number of pregnant HIV-infected women; • number of terminated pregnancies in HIV-infected women; • number of HIV-infected people tested for STIs; • number of HIV-infected people diagnosed with STIs; • number of HIV-infected people who have received STI treatment; • number of HIV-infected women tested for cervical cancer within the past three years; • number of deliveries to couples with at least one HIV-positive partner; and • number of deliveries after medically assisted conception in couples with at least one HIV-positive partner. Data collection methods should follow the principles of confidentiality and should not lead to the disclosure of identifiable patient information inside or outside the clinical setting. 347 support for sexual and reproductive health in people living with hiv Annex 1. Suggested topics and questions for taking a sexual history Begin the sexual history component by stating: “Since sex is an important part of overall health, we ask everyone the following questions. Please give only answers that you feel comfortable with me knowing.” Sexual orientation/identity 1. Do you have sex with men, women or both? 2. Do you consider yourself heterosexual, homosexual, bisexual or other? 3. If applicable: do you consider yourself male or female? a. Have you ever had hormone therapy? b. Have you had or considered having a sex change? c. Have you had or considered having any sex-change surgery? Sexual practices and sexual well-being 1. What kind of sex do you have: a. oral sex? b. vaginal sex? c. anal sex? d. other? 2. How do you protect yourself from HIV/STIs? 3. Do you ever use condoms or other barrier methods? 4.

Management of syphilis in PLHIV • Cell-mediated and humoral immunity may modify the natural course of syphilis infection in HIV-coin- fected individuals. • The diagnostic and treatment of syphilis-coinfected PLHIV may be different due to a rapid clinical course with unusual manifestations, including increased risk of neurological manifestations and increased treat- ment failure rates (6). • The recommended treatment for early syphilis does not change for PLHIV. When possible, the cerebro- spinal fluid (CSF) should be examined and a more intensive treatment be administered, regardless of the clinical stage of syphilis (92). • Clinical and serological evaluations of syphilis-coinfected patients should occur at 3, 6, 9, 12 and 24 months. • In case of treatment failure, re-treatment should be undertaken as appropriate (6). 351 support for sexual and reproductive health in people living with hiv Annex 3. Management of vulvovaginal candidiasis in women living with HIV The controversy over whether vulvovaginal candidiasis (VVC), particularly recurrent VVC, is more common in women living with HIV than in matched control HIV-negative women remains largely unresolved (93). Thus, it may be inappropriate to propose HIV testing in women with recurrent VVC. In women living with HIV, candidiasis frequently involves several sites, including the vulva and vagina. It is often severe and frequently relapses. The microbiological spectrum of VVC appears similar in HIV-positive and HIV-negative women (93). Treat- ment involves topical application of a wide variety of imidazoles (miconazole, clotrimazole, econazole, butoconazole, terconazole, etc.) or nystatin. Although more expensive, imidazoles require shorter courses of treatment and appear to be more effective than nystatin (94). Treatment principles are identical to those for HIV-negative women. There is no evidence of refractory VVC responding to conventional antifungal treatment. Repeated treatment may be required for women living with HIV. It is recommended that any predisposing factors such as antibiotic use, the use of antiseptic/antibiotic vaginal preparations or vaginal douching be reduced or eliminated. Simultaneous treatment of rectal focuses with oral nystatin or fluconazole is useful in preventing recurrences. Although treatment of sexual partners is not recommended, it may be considered for women who have recurrent infection. Table 13. vaginal candidiasis Antifungal agent Dose Frequency Route Duration First-line treatment Fluconazole 100 mg Single dose PO Once Clotrimazole 500 mg Single dose Vaginal Once Second-line treatment Ketoconazole 200 mg BID PO 3 days Ketoconazole 200 mg OD PO 7 days Maintenance therapy Nystatin 2–4 million IU BID PO 10 days or: Fluconazole 50–200 mg OD PO Every day Third-line treatment Ketoconazole 200 mg OD PO Depends on response, usually 7–10 days Itraconazole 100 mg OD PO Depends on response, usually 7–10 days PO: per os (orally) 352 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Annex 4. Management of bacterial vaginosis in women living with HIV Bacterial vaginosis (BV) is a clinical syndrome resulting from replacement of the normal hydrogen peroxide- producing Lactobacillus sp. in the vagina by high concentrations of anaerobic bacteria, such as Gardnerella vaginalis or Mycoplasma hominis. Additional studies are needed to confirm the relationship between altered vaginal microflora and the acquisition of HIV. • Treatment of sexual partners has not been demonstrated to be beneficial. • It is recommended that predisposing factors, such as the use of antiseptic/antibiotic vaginal preparations or vaginal douching, be reduced or eliminated. • The recommended regimen for BV is metronidazole 400 mg or 500 mg PO BID for seven days. Patients taking metronidazole should be cautioned not to consume alcohol while they are taking the drug and within 24 hours of taking the last dose. • Alternative regimens are: o metronidazole 2 g PO as a single dose o clindamycin 2% vaginal cream 5 g intravaginally at bedtime for seven days o metronidazole 0.75% gel 5 g intravaginally BID for five days o clindamycin 300 mg PO BID for seven days (93). 353 support for sexual and reproductive health in people living with hiv Annex 5. Cervical cancer screening methods 1. The classic screening test for cervical cancer is the Pap smear. A single Pap test may have a false nega- tive rate of 10–25% (90). Accuracy is significantly improved with regular periodic screening. Controlled studies have not demonstrated a decrease in Pap test sensitivity or specificity in HIV-positive women. To use Pap tests as a screening method, basic infrastructure to perform cervical cytology screening should be available at all health care levels. The Bethesda system of classification is recommended for both HIV- positive and HIV-negative patients (95). (See Annex 6 below.) 2. Alternative methods include visual inspection of the cervix (VIA) after application of 3–4% acetic acid, to differentiate normal cervical appearance from cervical lesions. This test is not recommended in set- tings where Pap smear is available. 3. Newer cervical screening techniques using liquid-based cytology increase sensitivity, albeit at greater cost, and offer the possibility of direct HPV DNA testing. The utility of this test in women living with HIV has not been assessed. 4. HPV testing using a high-risk HPV DNA test allows for the detection of oncogenic/non-oncogenic types and is recommended in case of borderline Pap results (ASC-US or ASC-H). 354 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Annex 6.

365 Prevention of Hiv transmission from Hiv-infected motHers to tHeir infants I. Policy issues • Clinical prevention of mother-to-child transmission of HIV (PMTCT) should be a part of the con- tinuum of care for HIV-infected women and their children. Services providing PMTCT should be linked to other relevant governmental and nongovernmental services, such as HIV treatment and care, reproductive health, paediatric services, drug-dependence treatment, harm-reduction services, psychosocial support, child protection services, etc. • Pregnant injecting drug users (IDU) should have the same non-discriminatory access to health care services – including antiretroviral treatment (ART), reproductive choices, PMTCT and ma- ternity care – as pregnant women who do not use drugs. • All medical records, whether or not they involve HIV-related information, should be treated ac- cording to appropriate standards of confidentiality. Only health care professionals with a direct role in the management of patients or clients should have access to such records, and only on a “need-to-know” basis. 366 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION II. Background Increasing numbers of women living with HIV are becoming pregnant, and their infants will be at high risk for acquiring HIV infection in utero, during labour or through breastfeeding. In the absence of interventions, the risk of mother-to-child transmission (MTCT) of HIV is 15–30% in non-breastfeeding populations; breastfeeding increases the risk to 20–45% (1). Effective interventions for the prevention of MTCT (PMTCT) of HIV infection do now exist. Where these interventions are freely available and utilized, MTCT rates of 1% or 2% have been achieved (1–3). They include: • antiretroviral (ARV) prophylaxis during pregnancy, labour and the first weeks of life; • obstetrical interventions, including pre-labour caesarean section (PLCS); and • avoidance of breastfeeding (4–6). The challenge is to achieve similar rates throughout the WHO European Region, particularly in countries where the HIV epidemic is fuelled by injecting drug use and health systems are adversely affected by economies in transition. Several factors – high-level coverage of antenatal care (ANC), the availability of an extensive health care infrastructure, high literacy levels, a relatively low number of infections and the existence of effective interventions to reduce MTCT – offer an opportunity to eliminate infant HIV infection in the Region and thus provide a model for the rest of the world. WHO promotes a four-pronged comprehensive strategic approach to the prevention of HIV infection in infants and young children: 1. primary prevention of HIV infection 2. prevention of unintended pregnancies among HIV-infected women1 3. prevention of HIV transmission from mothers to their infants 4. treatment, care and support for HIV-infected mothers and their families (7). This protocol focuses on the third prong of the strategy, prevention of HIV transmission from moth- ers to their children. It is consistent with the Region’s goal of preventing HIV in infants in Europe (8), specifically to eliminate HIV infection in infants by 2010 as indicated by reducing the infection rate among infants to less than 1 per 100 000 live births and the infection rate among infants born to HIV-infected women to less than 2%. The European goal is congruent with the global goal set at the 2001 United Nations General As- sembly Special Session (UNGASS) on HIV/AIDS of reducing the proportion of infants infected with HIV by 50% by 2010 (9). 1 Please see Protocol 9, Support for sexual and reproductive health of people living with HIV. Prevention of Hiv transmission from Hiv-infected motHers to tHeir infants III. Initial evaluation 1. Initial evaluation of pregnant women in antenatal care settings Antenatal HIV counselling and testing of pregnant women is an effective medical intervention that contributes to lowering rates of MTCT of HIV. In addition, it is an important entry point for the treatment and care of HIV-positive women and their children. The intend of HIV testing is to capture every HIV infected pregnant woman as early as possible in order to introduce a package of PMTCT interventions and minimize risk of HIV transmission to her baby during pregnancy, labour and postpartum. HIV testing should be voluntary and not forced. Women should provide written consent to the test and be able to refuse it. Testing should include obligatory counselling. An initial assessment for determining HIV status should include: • pretest counselling; • serological testing for HIV antibodies (typically ELISA and/or rapid tests2), followed by a west- ern blot confirmatory test if positive; and • post-test counselling, including information on reducing risky behaviour, irrespective of the results. For women infected with HIV, further evaluation is needed in collaboration with an HIV specialist to determine the clinical stage and to develop a PMTCT management strategy.3 Among the key aspects of pretest HIV counselling is identifying any drug use (including injecting drug use) and evaluating the risks of the woman’s exposure to HIV from sexual partners. Drug use and especially drug dependence can have a large impact on pregnancy and fetal development, and they require special medical assistance during pregnancy, labour and the postpartum period for both mother and fetus/infant. For more about the assessment of drug dependence and withdrawal symptoms in pregnant women, see section IV.2.3 below. 2. Patient counselling After the initial evaluation, HIV-infected pregnant women should be counselled on the following, where relevant to their condition: • condom use for prevention of sexual transmission of HIV and other STIs; • the risk of HIV transmission to the fetus/neonate and how to prevent it; • the risks and benefits of ARV prophylaxis as part of PMTCT strategy; • the risks of hepatitis B and C virus (HBV and HCV) perinatal transmission and how to reduce them; • the risks of perinatal syphilis transmission, and the need for treatment of syphilis, gonorrhoea and chlamydia to reduce the risk of HIV transmission; • the impact of drug use on fetal development, including drug withdrawal syndrome and drug interactions (see section IV.4.2 below); • referral to harm-reduction and drug-dependence treatment programmes, including substitution therapy where appropriate; 2 Rapid HIV serological testing should be available in maternities for those women only presenting in health care service dur- ing labour 3 For clinical and laboratory evaluation please refer to Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents. 367 368 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION • the implications of different modes of delivery in reducing the risk of HIV transmission, includ- ing the benefits and adverse effects of caesarean section (CS); and • instruction on infant feeding (see also section IV.3.1 below). With complete and accurate information about possible risks and management options, an HIV- positive woman can make an informed decision on whether to deliver or to terminate her pregnancy. Under no circumstance should she be coerced to terminate a pregnancy. 369 Prevention of Hiv transmission from Hiv-infected motHers to tHeir infants IV. PMTCT management in antenatal care settings and maternity wards Randomized controlled trials (RCTs), open-label trials and observational studies have provided evidence of the effectiveness of ARV prophylaxis (4, 10–24) and caesarean section in PMTCT. • Zidovudine (ZDV) administered early in pregnancy, during labour and delivery and postpartum to mother and infant has been shown to reduce vertical transmission from 25.5% to 8.3% in a non-breastfeeding population (25–27). • In mother–infant pairs receiving triple combination therapy including a protease inhibitor (PI), the MTCT rate can decrease to 0.9–1.3% (5, 28). • The protective role of caesarean section was demonstrated in both a meta-analysis (28) and a randomized clinical trial (RCT) (29) prior to the widespread use of combination therapy in preg- nancy. However, mounting observational data demonstrating very low levels of transmission in women on therapy with undetectable viral loads who deliver vaginally have led to changes in the advice on their method of delivery (30). • If the decision is made to perform pre-labour caesarean delivery to prevent HIV transmission, it should be done at 38 weeks’ gestation, as determined by the best clinical estimate, and amnio- centesis should be avoided (31). Administration of ARV regimen for PMTCT should be considered in close collaboration with health providers of ANC services and HIV specialists. The package of prevention interventions for preg- nant women should be based on: • the need for ART • the gestation stage at presentation • the level of the clinical setting (primary health care, specialist referrals) • the history of previous ARV use • the presence of concomitant diseases or conditions • the availability of ARVs. For HIV-infected pregnant women, PMTCT rates are those same for those who use drugs as for those who do not. The decision on when to start ART for pregnant women should be based on the WHO HIV/AIDS clinical staging system in combination with immunological criteria (see Protocol 1, Patient evalua- tion and antiretroviral treatment for adults and adolescents, Table 6 and Annex 2). 1. Possible scenarios for PMTCT management in ANC services and maternity wards The vast majority of HIV-positive pregnant women fit in one of the following categories: 1. those who do not presently need ART for the sake of their personal health (see Table 1) 2. those who do need or might need ART for the sake of their health (see Table 2) 3. those who started ART before pregnancy (see Table 3) 4. those who do not present until around labour (see Table 4). 370 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 1.1. Pregnant women who do not yet need ART for their own health Table 1. Pregnant Hiv-positive women who do not yet need art for their own health Gestational age and CD4 count ARVs during pregnancy ARVs during labour Postpartum ARVs Mode of delivery From 24–28 weeks CD4 >350 cells/ mm3 If viral load (VL) is available and ≤10 000 copies/ml and patient is ZDV-naive ZDV (300 mg) per os, twice daily (PO, BID) (32) Monitor haemo- globin level. If PLCS: Continue ZDVa only. If spontaneous labour before CS date: ZDV (300 mg)a every 3 hours until delivery + 3TC (150 mg), PO, BID + single-dose NVP (200 mg) at onset of labour With NVP during labour (preferred) Mother: ZDV (300 mg) + 3TC (150 mg) PO, BID x 7 days after deliveryb Infant: ZDV syrup (4 mg/kg body weight) + 3TC (2 mg/kg body weight) PO, BID x 7 daysc + single-dose NVP (2 mg/kg body weight) after birth PLCS at 38 weeks of pregnancy or spontane- ous deliveryd Without NVP during labour Mother: Stop ZDV.

If VL is unavailable or >10 000 copies/ml, or if there is a known history of ZDV exposuree ZDV (300 mg) + 3TC (150 mg) + SQV/rf (800 mg /100 mg) BID, POg Continue the same regimen until delivered Mother: Stop all three drugs after delivery. Infant: ZDV syrup (4 mg/kg body weight), PO, BID for 7 daysc . Start within first 8 hours. If VL <1000 copies/ml at 36–38 weeks, wait for spontaneous labour.h If VL >1000 copies/ml at 36–38 weeks. opt for PLCS at 38 weeks. If VL is unavailable and adherence to HAART <95%, opt for PLCS at 38 weeks. If VL is unavailable and adherence to HAART >95%, opt for sponta- neous labour.h a If intravenous (IV) ZDV is available, start continuous IV infusion four hours before PLCS (2 mg/kg for first hour and 1 mg/ kg/hour until cord is clamped). b ZDV + 3TC during labour and for seven days postpartum is administered to reduce risk of nevirapine (NVP) resistance in mother and infant. If mother hasn’t received NVP, stop ART after PLCS. c If mother received ARV prophylaxis for less than four weeks during pregnancy, the infant should receive ZDV for up to four weeks. In preterm infants the dose of ZDV should be 1.5 mg/kg IV or 2.0 mg/kg PO. d The woman should make the final decision of delivery method after knowing risks and benefits. In vaginal delivery, avoid invasive obstetrical procedures, such as fetal scalp monitoring and episiotomy. e If mother has been exposed to ART or is at risk for having a resistant virus, baseline resistance can help guide ART choice. f Lopinavir boosted with low dose ritonavir (LPV/r) (400 mg/100 mg) or nelfinavir (NFV) (1250 mg) BID, PO could be used as an alternative. g Adherence could be problematic due to pregnancy-associated complications. h Avoid invasive obstetrical procedures, such as fetal scalp monitoring and episiotomy. Episiotomy must not be performed routinely, but reserved for cases where there is a clear obstetric indication for the procedure (33). 371 Prevention of Hiv transmission from Hiv-infected motHers to tHeir infants 1.2. Pregnant women who need ART for their own health Pregnant women who need ART for their own health but have not yet received it should be given a first-line highly active antiretroviral treatment (HAART) regimen. ARV regimens containing ZDV, 3TC and NVP are recommended as first-line treatment options and for preventing MTCT (19, 34, 35). ART should be continued in such women after delivery for the benefit of their own health. Table 2. Pregnant Hiv-positive women who need or might need art for their own health Gestational age and CD4 count ARVs during pregnancy and labour Postpartum ARVs Mode of delivery Any gestational age CD4 <200 cells/mm3 ZDV (300 mg)a + 3TC (150 mg) + NVP (200 mg)b BID, PO Comments: Start NVP with 200 mg once daily (OD) for the first 2 weeks, and then con- tinue with 200 mg BID. Monitor liver enzymes at baseline, 2 weeks of treat- ment, 4 weeks, and every 4 weeks thereafter. Mother: Continue the same regimen Infant: ZDV syrup (4 mg/kg body weight) PO, BID for 7 days.c Start within first 8 hours. If VL <1000 copies/ml at 36–38 weeks, it is reason- able to await spontaneous labour.d If VL >1000 copies/ml at 36–38 weeks, opt for PLCS at 38 weeks. If VL unavailable and ad- herence to HAART<95%, opt for PLCS at 38 weeks. If VL unavailable and ad- herence to HAART >95%, opt for vaginal delivery. Any gestational age CD4 is 200–350 cells/mm3 ZDV (300 mg)a+ 3TC (150 mg) + SQV/r (800/100 mg)e BID, PO Mother: Decision to continue treat- ment postpartum should be based on clinical and immunological indicators, as normal physiologic changes, i.e. increase of circulating plasma volume (haemodilution) during pregnancy reduces the CD4 cell level, which then restores during postpartum. Infant: ZDV syrup (4 mg/kg body weight) PO, BID for 7 days.c Start within first 8 hours. a Close monitoring of haemoglobin is required. ZDV can be replaced by TDF or ABC in anaemic symptomatic women and women who are ZDV-intolerant. b The risk of NVP-associated hepatotoxicity substantially increases if CD4 >250 cells/mm3 (36). c If the mother received ARV prophylaxis for less than four weeks during pregnancy, the infant should receive ZDV up to four weeks. In preterm infants, the dose of ZDV should be 1.5 mg/kg IV or 2.0 mg/kg PO. d Risks and benefits should be discussed with the woman, who should make the final decision. In case of vaginal delivery, avoid invasive obstetrical procedures such as fetal scalp monitoring and episiotomy. Episiotomy must not be performed routinely, but reserved for cases with a clear obstetric indication (33). e LPV/r (400/100 mg BID) or NFV (1250 mg BID, PO) can be used instead of SQV/r. If PIs are not available, efavirenz (EFV) can be administered, but not earlier than the second or third trimester, due to risk of teratogenicity associated with its use in the first trimester. 372 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 1.3. Pregnant women who initiated ART before pregnancy Table 3. Pregnant Hiv-positive women who initiated art before pregnancy Gestational age ARVs during pregnancy and labour Postpartum ARVs Mode of delivery Any age Continue current ARV regimen if it does not contain EFV. If a woman is on a regimen that con- tains EFVa and is in her first trimes- ter, consider substituting SQV/r 800 mg/100 mgb or ABC; where CD4 count <250, NVPc can be used. The benefits of a second-line regimen outweigh the risks. Keep on current regimen during pregnancy, labour and afterwards. Mother Continue same maternal ARV treatment after delivery. Infant Oral ZDV syrup (4 mg/ kg body weight) BID for 7 days. Start within first 8 hours. In preterm infants the ZDV dose is 1.5 mg/kg IV or 2.0 mg/kg PO. If VL <1000 copies/ml at 36–38 weeks, await spontaneous labour.d If VL >1000 copies/ml at 36–38 weeks opt for PLCS at 38 weeks. If VL is unavailable and adherence to HAART <95%, opt for PLCS at 38 weeks. If VL is unavailable and adherence to HAART >95%, opt for spontane- ous labour.d a Anecdotal cases of neural tube defects have been reported with EFV use in the first trimester. While it is important to discon- tinue EFV in the pre-conception period, the decision to replace EFV with another ARV should be carefully considered. Switch- ing to another drug has the potential of viral rebound, while the fetus’s neural tube formation should be finished by six weeks of gestation. In many western European hospitals, experienced HIV physicians continue an EFV-based regimen if the woman first presents to ANC providers at eight weeks of pregnancy or later. If a decision is made to stop EFV, do not discontinue the EFV-containing regimen without switching to another ARV compound in order to avoid the risk of non-nucleoside reverse transcriptase inhibitor (NNRTI) resistance. b LPV/r (400 mg/100 mg) or NFV (1250 mg) BID, PO can be used instead of SQV/r. c The risk of NVP-associated hepatotoxicity substantially increases if CD4 >250 cells/mm3 (36); for dosage refer to Table 2 above. d Risks and benefits should be discussed with the woman, who should make the final decision regarding the delivery method. In case of vaginal delivery, avoid invasive obstetrical procedures such as fetal scalp monitoring and episiotomy. Episiotomy must not be performed routinely, but reserved for cases with a clear obstetric indication (33). 373 Prevention of Hiv transmission from Hiv-infected motHers to tHeir infants 1.4. Pregnant women who first present around labour Women presenting in labour without any antenatal assistance are often from vulnerable popula- tions, such as IDUs or sex workers. It is important to assess their HIV status, as they may be at high risk for being infected. Offer a rapid test, and provide ARV prophylaxis for PMTCT if the woman is found to be HIV-positive after confirmation by western blot. Table 4. Pregnant Hiv-positive women who first present in labour (no arvs during pregnancy) Time of admission to hospital ARVs during labour and delivery Postpartum ARVs Mode of delivery During labour and delivery ZDV (300 mg) every 3 hours until delivery + 3TC (150 mg) at onset of labour and then every 12 hours until delivery + NVP (200 mg once) at onset of labour Mother ZDV (300 mg) + 3TC (150 mg) BID x 7 days after deliverya Infant b ZDVc 4 mg/kg body weight BID for 4 weeks + 3TC 2 mg/kg body weight BID for 4 weeks + single-dose NVP 2 mg/kg at 48–72 hours after birthd Spontaneous vaginal delivery.e Avoid invasive obstetri- cal procedures such as fetal scalp monitoring and episiotomy. a Further strategy for the ART and case management of a woman identified as HIV-infected during labour should be based on CD4 count, VL and clinical examination as soon as possible after delivery. b Postpartum AZT and 3TC for infants should be initiated between 8 and 12 hours after birth if the mother received AZT and 3TC prophylaxis during labour and as soon as possible after birth if the mother did not receive ARV prophylaxis during la- bour. c In preterm infants, the dose of ZDV should be 1.5 mg/kg IV or 2.0 mg/kg PO. d If the mother misses a NVP dose, or takes NVP less than two hours before delivery, then the infant should be given an NVP dose immediately after delivery and a second dose at age 72 hours. e For women not in active labour and with intact fetal membranes, PLCS can be suggested. 1.5. PMTCT in pregnant HIV-infected women with active tuberculosis For HIV-infected pregnant women with active tuberculosis (TB), the first priority should be to treat the TB. For more information about TB treatment, refer to Protocol 4, Management of tuberculosis and HIV coinfection. • Most first-line anti-TB drugs are safe for use during pregnancy except streptomycin, which is ototoxic to the fetus. • If the length of the TB treatment jeopardizes ARV prophylaxis of MTCT, then ARV prophylaxis has to be prescribed concomitantly with the TB treatment. • ARV regimens containing NVP or unboosted PIs should not be used concomitantly with ri- fampicin due to drug interactions (37–41). • The recommended ARV regimen for PMTCT in HIV-infected pregnant women receiving ri- fampicin is ZDV + 3TC + SQV/r (for dosage, refer to Protocol 1, Patient evaluation and antiret- roviral treatment for adults and adolescents). Close monitoring of liver enzymes is required. In the absence of SQV/r, ABC may also be considered. However, further research on use of ABC in pregnant women is needed. • ZDV/3TC/ABC is available as a fixed-dose combination (three drugs in one tablet). Triple-nucle- oside or nucleotide reverse transcriptase inhibitor (NRTI) regimens appear to be less potent than NNRTI and boosted PI regimens (42). • If rifabutin is used instead of rifampicin, ARV regimens for the purpose of PMTCT remain as described above. Rifabutin levels may increase when coadministered with LPV/r; consequently, the rifabutin dosage may have to be reduced (37). 374 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 2. Management of HIV-infected active IDUs during pregnancy Pregnant women using drugs have a greater than normal risk of medical complications. They should be managed according to the possible impact their dependency has on their pregnancy, their fetus and their own health (see Table 6 below) (43).The key issue for the management of drug-using pregnant women is therefore stabilization of illicit drug use or its reduction to the lowest possible level. 2.1. Organization of services To manage pregnant HIV-positive IDUs effectively, they need to be persuaded to utilize health care services as early in pregnancy as possible, and the relevant services need to be accessible during the entire pregnancy. A key strategy is a team approach centred around antenatal, intrapartum and postpartum services that are linked to: • harm-reduction services that refer pregnant IDUs to ANC • drug-dependency treatment experts (throughout the pregnancy) • HIV/AIDS services • psychological and social services. 2.2. Assessment of drug dependence and withdrawal symptoms in pregnant women Underreporting of illicit drug use is common. Women who admit substance use, as well as those who do not but have injection marks or other signs suggesting such use (see Table 5), should be examined further. Drug-using women are often dependent on more than one psychoactive substance (nicotine, alco- hol, cannabis, opiates, cocaine, ecstasy, other amphetamines, benzodiazepines) (44), and clinical signs and symptoms of use and withdrawal can be difficult to identify. It is also important to dif- ferentiate clinical signs of pregnancy and symptoms of pregnancy complications from signs and symptoms of drug intake or withdrawal. Table 5. signs and symptoms of withdrawal from specific substances during pregnancy Substance Signs/symptoms Alcohol Agitation, tremors, sleep disturbance, tachycardia, hyper- tension, nausea, dilated pupils, seizures Delta-9-tetrahydrocannabinol (in cannabis, marijuana, hashish) Restlessness, irritability, mild agitation, insomnia, nau- sea, cramping Tobacco (e.g. cigarettes) Irritability, restlessness, difficulty concentrating, im- paired task performance, anxiety, hunger, weight gain, sleep disturbance, cravings, drowsiness Central nervous system (CNS) sedative hypnotics: alprazolam, barbiturates, chlordiazepoxide, diazepam, flurazepam, gluthethimide, meprobamate, methaqualone, etc. Tremulousness, insomnia, chronic blink reflex, agita- tion, toxic psychosis, seizure, anxiety, agitation, muscle cramps, sleep disturbance, hypertension, fever, anorexia CNS stimulants: methamphetamines, cocaine, methyl- phemidate, phenmetrazine, dimethyltryptamine, phen- cyclidine (PCP) Muscle aches, abdominal pain, hunger, prolonged sleep, suicidal ideas, bradycardia, craving, depression Opiates: codeine/oxycodone, heroin, hydromorphone, tripelenamine Flu-like syndrome, agitation, dilated pupils, abdominal cramps, insomnia, anxiety, craving, tachycardia, hyper- tension Source: adapted from Rayburn & Bogenschutz (45). 375 Prevention of Hiv transmission from Hiv-infected motHers to tHeir infants Women who use drugs may or may not be drug dependent. As drug dependency has implications for patient management strategy, it is crucial to assess it. A simple and rapid initial assessment can be done by ANC staff, based on 10 questions adapted from ICD-10 symptom checklist for mental disorders (see Annex 3 in Protocol 5, HIV/AIDS treatment and care for injecting drug users). Sev- eral other validated and standardized drug-dependence screening and assessment instruments are available, including the Addiction Severity Index (ASI) (see Annex 1 of the same protocol for Eu- ropean version 6 (EuropASI6)) (44). However, further evaluation of drug-dependence severity and appropriate treatment strategy should be done by or in close collaboration with a drug dependency treatment expert. 2.3. Impact of psychoactive substances during pregnancy and withdrawal The effects of psychoactive substances during pregnancy are divided into the effects of drug use on the fetus and neonate (Table 6) and withdrawal symptoms (Table 5 above). Table 6. the effects of psychoactive substances on the fetus, neonate and pregnancy outcome Substance Effects Alcohol Spontaneous abortion, microcephaly, growth deficiency, CNS dysfunction including mental retardation and behavioural abnormalities, craniofacial abnormalities (short palpebral fissures, hypoplastic philtrum, flattened maxilla), behavioural abnormalities.

Source: adapted from Rayburn & Bogenschutz (45). 2.4. Counselling on drug dependency and its treatment Counselling is an essential component in managing treatment of drug-dependent HIV-infected pregnant women. It should cover all the issues mentioned in section IV.1, with emphasis on the following: • the risks to the fetus and neonate from drugs; • the benefits of opioid substitution therapy (OST) for the health of both mother and fetus; • the risk of fetal stress due to uncontrolled withdrawal attempts without medical and psychologi- cal support;4 • the effects of pregnancy on OST dose maintenance and the possible need to increase it;5 • interactions between opioid substitutes and ARVs as part of PMTCT; and • adherence to OST and ART. 4 It is important that mothers understand that the fetus will also experience withdrawal symptoms. 5 To avoid resistance to a dosage increase, the patient should be reassured that it has no relationship to drug dependency in the newborn child. 376 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 2.5. Opioid substitution therapy during pregnancy If opioid-using pregnant women meet the criteria for dependency (see Annex 4 in Protocol 5, HIV/ AIDS treatment and care for injecting drug users) they should be counselled about the risks and benefits of OST, and an agreement should be reached for a treatment programme and adherence to it (44, 46, 47). Medications for the treatment of drug dependency (both opioid and non-opioid) in pregnant women are shown in Annex 1 of the present protocol. 2.5.1. Methadone substitution therapy (46) Methadone substitution treatment is the currently recommended standard of OST for dependent preg- nant women. OST prevents resumption of illicit drug use, withdrawal symptoms and craving, and it also reduces pregnancy-related complications (44, 46). It should be combined with prenatal care and psychosocial counselling, such as support groups, community reinforcement, contingency treatment, cognitive behavioural skills training, motivational therapy and marital behavioural therapy. Data show that medical withdrawal of opioid-using pregnant women (including those on metha- done) during pregnancy carries an increased risk to the fetus of intrauterine death, even under the most optimal conditions (46). There is evidence that methadone maintenance treatment, combined with prenatal services, promotes fetal growth, while continued use of heroin during pregnancy may result in infant morbidity (46). Table 7. advantages and disadvantages of methadone treatment for pregnant women Advantages Disadvantages Avoids contaminants that may harm the unborn child. No known fetal abnormalities are associated with pure heroin or methadone. Involves a known, regular dose. Avoids periods of drug withdrawal that may be associ- ated with miscarriage early in the pregnancy, or fetal growth retardation and stillbirth late in pregnancy. Reduces the incidence of premature birth. Reduces the risk of intra-uterine growth retardation. Increases use of ANC services. Increases the severity and duration of neonatal with- drawal compared to that of infants of untreated opioid- dependent mothers. Involves longer hospitalization and treatment of newborn infants. Leads to greater neonatal weight loss. Reduces demand of infant to feed. Source: Brown et al. (46). Methadone is a long-acting substance which, if prescribed in adequate dosage, provides a relatively non-stressful environment in which the fetus can develop throughout pregnancy. Methadone provi- sion should begin as early in pregnancy as possible; starting in the first trimester of pregnancy is optimal for both fetus and mother, and is associated with higher birth weights. 2.5.1.1. Dosage Methadone dose should always be individually determined by the absence of subjective and objec- tive abstinence symptoms and reduction of drug craving. The lowest effective dose should be used. Doses below 60 mg/day are not effective, and low-dose policies for pregnant patients often result in increased illicit drug use as well as reduced programme retention (46). A small number of metha- done patients are aberrant metabolizers, and some medications may speed liver metabolism. Such cases may require doses in excess of 120 mg/day. 2.5.1.2. Dosage reduction (detoxification) Once a patient is stabilized on methadone, it should be decided in consultation with her whether a slow reduction, finishing sometime before the birth, is realistic, or whether methadone maintenance 377 Prevention of Hiv transmission from Hiv-infected motHers to tHeir infants must continue. Dose reduction is only possible to consider if the pregnancy is stable and has reached the second trimester. Dose reductions of 2.5–5.0 mg per week are considered safe (46). Withdrawal symptoms should be avoided as much as possible, as they cause the fetus considerable distress. 2.5.1.3. Dosage increase During the later stages of pregnancy, methadone dosage may have to be increased or split (half each in the morning and evening) to produce a beneficial effect since greater plasma volume, an increase in plasma proteins that bind methadone and renal blood flow during pregnancy can contribute to a reduced plasma blood level of methadone. It may therefore be necessary to increase the methadone dosage by 5–10 mg to avoid withdrawal symptoms and prevent concurrent drug use. Note that the administration of NVP or EFV as part of a PMTCT regimen requires an increase of methadone. 2.5.1.4. Interactions between methadone and ARVs Interactions between methadone and ARVs are the same in pregnant women as in other patients (cf. Protocol 5, HIV/AIDS treatment and care for injecting drug users, section on Drug-drug interac- tions and IDUs). If a pregnant woman receives an NNRTI (NVP or EFV) as part of a PMTCT regi- men, the dose of methadone has to be increased, as NNRTIs significantly decrease concentration of methadone and generate withdrawal symptoms. In a case series of chronic methadone recipients initiating NVP, 50–100% increases in the daily methadone doses were required to treat opiate withdrawal. Withdrawal symptoms generally oc- curred between four and eight days after starting NVP (46). Methadone significantly increases ZDV concentration (up to 43%), which may increase the risk for adverse effects; consequently, close monitoring is required. SQV/r slightly reduces levels of methadone; no dosage adjustment is necessary, but continual moni- toring is required. 2.5.2. Buprenorphine substitution therapy As a Category C drug,6 buprenorphine has implications for pregnancy (49–51). While studies have not shown that buprenorphine is harmful to the fetus, it cannot be recommended for pregnant or lactating women. Its use can be considered if potential benefits justify the risks to the fetus (52), for example, if methadone is not available or the patient cannot tolerate it. Women should be informed about the risks of buprenorphine use, and its use for patients who are or may become pregnant should be made carefully and on a case-by-case basis. Limited case reports from Europe and Aus- tralia indicate that doses can range from 0.4 to 24 mg/day, with pregnancies generally progressing normally (50). 2.6. Management of HIV-infected drug-dependent women presenting in labour The majority of drug-using women do not attend ANC and only arrive at the maternity ward around the time of labour. In such cases, maternity wards should be prepared to: • assess drug use dependence (see Protocol 5, HIV/AIDS treatment and care for injecting drug us- ers, Annex 1) and inform the neonatologist; • offer rapid HIV testing if status is unknown or was negative during pregnancy; • provide relevant treatment for withdrawal symptoms; • initiate OST as necessary; and • counsel about the effects of drugs on pregnancy outcome, on the newborn infant and on treat- ment approaches. 6 According to the United States Food and Drug Administration, a Class C rating for use during pregnancy means that studies in animals have revealed adverse effects on the fetus (teratogenic, embryocidal or other) and that there are no controlled studies in women or studies in animals (48). 378 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION See Table 4 above for a PMTCT regimen for HIV-infected women who have not received ARV prophylaxis during pregnancy, irrespective of their drug-dependence status. For opioid-depend- ent women presenting in the maternity ward who receive ARVs at the onset of labour, methadone should be sufficient to prevent withdrawal symptoms. 2.6.1. Pain relief  Pain relief requires special attention during labour and the postpartum period, especially after CS. Pain management for opioid dependent pregnant women should be addressed in the same way as for other pregnant woman. A higher dose of analgesia may be needed to relieve pain (53). Epidural anaesthesia should be used as early in delivery as possible, and can be continued in the early postpartum period, especially after CS. 3. Postpartum management PMTCT postpartum pharmacological management is described in Tables 1–4 above. All women with HIV infection should also be counselled on infant feeding options and contraception while in the maternity ward. 3.1. Counselling on infant feeding Even when peripartum ARV prophylaxis is used, infants remain at substantial risk of acquiring infection during breastfeeding, which has been shown to result in HIV transmission to 14% of at- risk infants (54–56). WHO recommends that HIV-infected mothers do not breastfeed at all when replacement feeding is acceptable, feasible, affordable, sustainable and safe (for definitions of these terms, see Annex 2). Otherwise, exclusive breastfeeding is recommended during the first months of life and should be discontinued as soon as these conditions for replacement feeding are met. Evi- dence suggests that exclusive breastfeeding in the first three months carries a lower risk of transmis- sion than mixed feeding, which is therefore not recommended (57, 58). Counselling on infant feeding should stress the risks of transmission through breastfeeding and recommendations for replacement feeding, the importance of not breastfeeding during replacement feeding and how to safely prepare and administer the food. Mothers should have a follow-up visit to the paediatric outpatient clinics within two weeks after birth to check and ensure that there are no feeding problems. 3.2. Counselling postpartum contraception Condoms remain the preferred option for reducing the risk of unintended pregnancy and HIV trans- mission. Lactational amenorrhoea (LAM) cannot be recommended as a contraceptive method, since breastfeeding is not recommended. (For more information, refer to Protocol 9, Support for sexual and reproductive health of people living with HIV, section on Lactational amenorrhea method.) 4. Neonate management in the maternity ward 4.1. Laboratory diagnosis of HIV in neonates The first deoxyribonucleic acid polymerase chain reaction (DNA PCR) test for HIV should be performed within 48 hours of birth. Testing of the umbilical cord blood should not be done due to possible risk of contamination with maternal blood. A positive test will provisionally mean that the newborn infant is infected. A second HIV DNA test at six to eight weeks from birth should be performed regardless of the outcome of the first test. If PCR is not available, an HIV antibody test is recommended at 15–18 months, with a confirmatory western blot test. HIV diagnostic testing for infants should be accompanied with counselling for caregivers, explain- ing the results and the need for additional testing to definitively determine the child’s infection status. 7 For further information regarding pain management for IDUs, refer to Protocol 5, HIV/AIDS treatment and care for inject- ing drug users, section on Management af acute and chronic pain. 379 Prevention of Hiv transmission from Hiv-infected motHers to tHeir infants Please see the algorithm 1 for HIV diagnosis in infants in Protocol 11, Paediatric HIV/AIDS treat- ment and care, section on laboratory diagnosis of HIV. 4.2. Management of dependence and withdrawal syndrome in neonates 4.2.1. Clinical examination Neonatal withdrawal or abstinence syndrome (NAS) occurs in 50–80% of infants exposed to opio- ids in utero, usually within the first 24–72 hours after birth. However, only 5–20% of these infants have severe symptoms and need pharmacotherapy (59). NAS from buprenorphine peaks within three or four days and lasts for five to seven days. NAS from methadone generally lasts up to four days (60). Clinical symptoms of NAS vary in severity and duration and include: • tremors, increased muscle tone, restlessness, sleeping problems, protracted crying and hyperac- tive reflexes; • regurgitation, vomiting and diarrhoea; • tachypnea; and • minor symptoms, such as fever, sneezing, sweating, nasal stuffiness and yawning. Infants of mothers known or suspected to be drug users who are showing signs of withdrawal should be scored every four hours. The scoring should be applied in a consistent manner. Please see the scoring system for the signs and symptoms of NAS in Annex 3, which provides a basis for deciding treatment dosages (see Table 8 in the next below). 4.2.2. Treatment of NAS (51) The aim of NAS treatment is to give the infant the chance to rest, get enough sleep and eat enough food; it will not eliminate all symptoms. The treatment should be carried out as follows. • First stage is: supportive therapy. Provide a low-stress environment (quiet room, reduced illu- mination, swaddling, holding, hammock, pacifier), frequent small feedings (on demand) and no abrupt changes. If symptoms worsen, proceed to the second stage. • Second stage is: pharmacological therapy. Phenobarbital solution is the agent of choice. If it is not successful or if convulsions occur, switch to morphine solution. Therapeutic doses for NAS treatment vary depending on NAS score; see Table 8 below, and Annex 3 for scoring. Occasion- ally, vomiting may be very serious, in which case replace the pharmacological agent temporarily with chlorpromazine (2–3 mg/kg/day in 3 or 4 doses intramuscularly (IM)). 380 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Table 8. therapeutic doses for nas Abstinence score Phenobarbital solution Morphine solution 8–10 6 mg/kg/day in 3 doses 0.32 mg/kg/day in 4 doses 11–13 8 mg/kg/day in 3 doses 0.48 mg/kg/day in 4 doses 14–16 10 mg/kg/day in 3 doses 0.64 mg/kg/day in 4 doses 17+ 12 mg/kg/day in 3 doses 0.80 mg/kg/day in 4 doses Source: adapted from Finnegan et al. (51) Interactions between ARV drugs for neonates as part of PMTCT and the severity of the NAS treat- ment have not yet been studied. 4.3. Immunization In countries with an incidence of more than 20 TB cases per 100 000 population (61), all HIV- exposed asymptomatic children should be immunized with bacille Calmette-Guérin (BCG) in the maternity ward on the same schedule as infants who have not been exposed to HIV. In countries with low TB incidence, BCG vaccine should not be administered to HIV-infected chil- dren, regardless of their clinical stage or immunodeficiency status. Other vaccinations should be considered, taking into account the national vaccination programmes. For further recommendations concerning immunization, please refer to Protocol 12, Immunization of people living with HIV and people at risk for HIV infection. 5. Referrals The continuum of care for HIV-infected women, their neonates and their families requires a team approach that should ensure provision of: • paediatric care for the neonate, including HAART and prevention of opportunistic infections in the first year of life, if indicated; • postpartum contraception for the mother; • treatment and care of HIV/AIDS; and • treatment for drug dependency and harm reduction. To ensure proper follow-up, detailed reports on the ART received by the mother and neonate in the maternity ward should be sent to the mother’s and child’s physicians. For further information on treatment and care please refer to protocols 1, Patient evaluation and antiretroviral treatment for adults and adolescents and 11, Support for sexual and reproductive health in people living with HIV. 381 Prevention of Hiv transmission from Hiv-infected motHers to tHeir infants V. Suggested minimum data to be collected at the clinical level The suggested minimum data to be collected are important in the development of key indicators on access to PMTCT services and its success. Such indicators assist managers in decision making on ways to strengthen and expand these services to all women who need them. The following data should be collected at the clinical level on a regular basis (e.g. monthly, quar- terly or semi-annually): Antenantenal care services should collect data on the: • number of pregnant women • number of pregnant women who were tested for HIV • number of pregnant women who tested positive for HIV • number of HIV-infected pregnant women who had an abortion • number of HIV-infected pregnant women who received ARV prophylaxis during pregnancy • number of HIV-infected pregnant women who are opioid-dependent injecting drug users • number of HIV-infected pregnant women receiving OST • number of HIV-infected pregnant women receiving OST and ARV prophylaxis. Maternity services should collect data on the: • number of HIV-infected pregnant women who presented in the maternity services; • number of pregnant women who presented in the maternity services without prior HIV testing during pregnancy: ° among these how many received a rapid HIV test: - among these how many tested HIV positive; • number of HIV-infected pregnant women who presented in the maternity services without receiving ARV prophylaxis during pregnancy; • number of HIV-infected pregnant women who received ARV prophylaxis during labour; • number of HIV-infected opioid-dependent injecting drug users in the maternity services: ° among these how many received OST treatment during labour; • number of HIV-infected pregnant women who had a vaginal delivery; • number of HIV-infected pregnant women who had a planned caesarean section; • number of neonates born to HIV-infected women: ° among these number who received ARV prophylaxis; ° among these how many received milk formula feeding; ° among these how many received exclusive breastfeeding; • number of HIV-infected neonates, born to HIV -infected mothers, diagnosed by PCR; • number of neonates born to opioid dependent women; • number of neonates who received NAS treatment. 382 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Annex 1.

Definitions of acceptable, feasible, affordable, sustainable and safe replacement feeding The following terms can serve as a starting point that should be adapted in the light of local conditions and unfolding research. Acceptable. The mother perceives no barrier to replacement feeding, whether due to cultural or social causes or to fear of stigmatization or discrimination. If replacement feeding is acceptable to the mother, either she is under no social or cultural pressure to breastfeed and is supported by fam- ily and community in opting for replacement feeding, or she will be able to cope with pressure to breastfeed and deal with any stigma attached to replacement feeding. Feasible. The mother (and family) has the time, knowledge, skills and other resources needed to prepare the replacement food and feed the infant up to 12 times every 24 hours. The mother can understand and follow the instructions for preparing infant formula, and with family support where available she can prepare sufficient replacement food every day, and at night, despite any disrup- tions it might cause in preparation of other family food or other work. Affordable. The mother (and family), with community or health-system support if necessary, can pay the cost of purchasing/producing, preparing and using replacement food, including all ingredi- ents, fuel, clean water, soap and equipment, without compromising the health and nutrition of the family. The concept of affordability also extends to access to medical care for diarrhoea if necessary and the cost of such care. Sustainable. A continuous and uninterrupted supply and dependable system of distribution for all ingredients and products needed for safe replacement feeding should be available for as long as the infant needs it, up to one year of age or longer. If replacement feeding is sustainable, there should be little risk that formula will ever be unavailable or inaccessible, and another person will always be available to prepare the food and feed the child in the mother’s absence. Safe. Replacement foods should be correctly and hygienically prepared and stored, and fed in nu- tritionally adequate quantities with clean hands and utensils, preferably using a cup. Safety means that the mother or caregiver is able to: • access a reliable supply of safe water (from a piped or protected-well source); • prepare replacement food that is nutritionally sound and free of pathogens; • wash hands and utensils thoroughly with soap and regularly sterilize the utensils; • boil water to prepare each of the baby’s feedings; and • store unprepared food in clean, covered containers protected from rodents, insects and other animals. Source: adapted from WHO (57). If the above criteria are not met, exclusive breastfeeding is recommended during the first months of life and should then be discontinued as soon as feasible. HIV-positive mothers should be helped to make the best choice according to their circumstances and to carry out their decision. They should thus receive counselling that includes information about the risks and benefits of various infant feeding options, based on local conditions, and guidance in selecting the most suitable option for their situation. Whichever infant feeding option is chosen, mothers should be supported in carrying it out safely and appropriately. While commercial infant formula will be acceptable, feasible, af- fordable, sustainable and safe for many HIV-positive women in the European Region, some women will choose other options in accordance with their personal circumstances. 385 Prevention of Hiv transmission from Hiv-infected motHers to tHeir infants Annex 3.

Introduction The increasing number of reported paediatric AIDS cases in European countries (1) demands urgent action to improve survival and quality of life for the affected children. The core component of treatment and care of infants and children infected with HIV is provision of antiretroviral treatment (ART). Optimal ART increases the length and quality of their lives. The goals of paediatric ART are the same as for adults and adolescents, the prolongation of life and improvement of its quality (see Protocol 1 Patient evaluation and antiretroviral treatment for adults and adolescents). Policy for ART in paediatric HIV/AIDS cases should be based on the following principles. • Antiretroviral (ARV) treatment should be available as part of a comprehensive package of pae- diatric HIV care. • It should be consistent with Protocol 10 Prevention of HIV transmission from HIV-infected mothers to their infants. • Paediatricians should provide routine care and collaborate closely with paediatric HIV special- ists to monitor HIV progression and the need for ART. • A continuum of care should be assured during childhood, during transition to adolescence and adulthood and in line with future treatment and care for adolescents and adults (see Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents). 394 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION II. Laboratory diagnosis of HIV 1. Diagnosis of children ‹18 months of age In children <18 months, virological assays are recommended for detecting plasma HIV DNA (2), plasma HIV RNA (3–7) and immune complex-dissociated (ICD) p24 antigen (8–10). Virological tests have recently become technically easier, less expensive and more reliable. 1.1. Diagnosis in non-breastfeeding infants See the algorithm in Fig. 1 below. • The probability of HIV diagnosis by DNA assay increases with age; 38% of infected children have positive DNA PCR tests by the age of 48 hours. By age 28 days, DNA PCR has 98% sen- sitivity (11) and 99% specificity in identifying HIV pro-viral DNA (12). • Infants with a positive virological test at age 48 hours may have an intrauterine infection. • Infants with a negative virological test during the first week of life and subsequent positive tests have an intrapartum infection (13). • HIV infection can be diagnosed by HIV DNA or RNA detection in most infected non-breast- feeding infants by age 1 month and in virtually all infected infants by age 6 months. • Blood samples from the umbilical cord should not be used for diagnostic evaluations because of potential contamination from maternal blood. • A first virological test should be performed on infants about 48 hours after delivery, before mother and infant are discharged.1 A positive virological test (usually DNA) means that the infant is “provisionally HIV-infected”; a negative result at this stage suggests an indeterminant status. • The second virological test should be done at around 6 weeks of age. This is the key test for infants who tested negative with the first virological test. If this test is now positive, usually test- ing algorithms require confirmation by a repeat test on a separate specimen for confirmation. • A second positive virological result indicates that the infant is HIV-infected and should be clini- cally evaluated to develop a management strategy, see section III below. • If a second virological test is negative the infant is assumed to be uninfected, however, regular monthly monitoring for signs of HIV infection should be conducted and if resources are avail- able, a third virological test may be offered at age of 3 months. 1 In settings with limited resources or access to virological tests it may be more efficient and cost effective to conduct initial virological testing at 6 weeks or age, as HIV infection status can be reliably determined in almost all children at this stage (fol- low algorithm 1 from where 2nd test begins). 395 Paediatric HiV/aidS treatment and care a This may be the first diagnostic algorithm if testing at the age of 48 hours is not available. b Usual confirmatory test should be followed on a new specimen. 1st Virological test (48 hours after birth) positive negative Status: provisionally HIV- infected 2nd Virological test Usually performed from 6 weeks of agea positiveb negative Status: Indeterminant Status: assumed healthy Confirmation & clinical evaluation; HIV treatment and care Monitor for signs of HIV infection If signs appear before 18 months, repeat virological test Status: HIV-infected If resources are available, repeat virological test at age 3 months Fig 1. HiV virological diagnosis in non-breastfed infants born to HiV-infected mothers 396 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 1.2. Diagnosis in breastfeeding infants • WHO EURO does not recommend breastfeeding for infants born to HIV-infected mothers. • If alternative feeding is not available and an infant is breastfeeding, virological assays can be performed any time. If the result is negative then it should be conducted at least six weeks after complete cessation of breastfeeding, to confirm that the infant is not HIV-infected. 1.3. Diagnosis in infants exposed to ARV prophylaxis • ARV prophylaxis to avoid mother-to-child transmission (MTCT) does not affect HIV DNA test results. HIV DNA remains detectable in the peripheral blood mononuclear cells of an HIV-in- fected child. • The sensitivity of HIV RNA may be affected by ARV prophylaxis. Therefore, if the HIV RNA assay was negative while the infant was receiving prophylaxis, it should be repeated at least two weeks after prophylaxis has been completed. 1.4. Diagnosis in infants born to mothers on ART • Infants of mothers who are on ART or have a low or undetectable viral load at delivery and do not breastfeed can be considered at low risk for acquiring infection (14). • Given the relatively high ARV levels found in breastfeeding infants, it is not known whether maternal ART during breastfeeding affects RNA detection in the infant. • DNA detection is unaffected by maternal ART. 2. Diagnosis in children ≥ 18 months old • By the age of 12 months, most uninfected HIV-exposed children will have lost maternal anti- bodies. HIV antibody testing with a positive result in a child at this age usually indicates HIV infection (96% specificity) (15). • Definitive HIV diagnosis in children ≥18 months old (whether HIV exposure is known or un- known) can be performed with antibody tests (ELISA or rapid test), while Western Blot has been used in the past, confirmation of HIV status is more reliably established with virological testing. • Some clinical conditions are very unusual in the absence of HIV infection (Pneumocystis pneu- monia, oesophageal candidiasis, lymphocytic interstitial pneumonitis (LIP), Kaposi sarcoma and cryptococcal meningitis). Diagnosis of such conditions and other stage 3 and 4 clinical (see Annex 1) diagnoses suggests HIV infection and indicates the need for an HIV antibody test. 397 Paediatric HiV/aidS treatment and care III. Clinical management of HIV-infected children 1. Clinical and laboratory evaluations of HIV-infected children All infants and children who are diagnosed with HIV infection should undergo clinical and labora- tory evaluations to determine the stage of HIV clinical disease and immunodeficiency, eligibility for ART and other morbidities or issues to be addressed. This baseline assessment will also provide an opportunity to initiate cotrimoxazole preventive therapy and should serve as an opening to offer counselling and support to infected children and their parents/caregivers. Clinical and laboratory evaluation of children with HIV should include the following: • current clinical signs and symptoms to establish clinical stage (see Annex 1); • exposure to and risk for coinfections (tuberculosis (TB), hepatitis B, hepatitis C); • identification of comorbidities and medications taken to treat them; • history of previous exposure to ARVs, including drugs used for prevention of mother-to-child transmission (PMTCT); and • laboratory tests: o complete blood count; o CD4 cell count (absolute and percentage for children <6 years old); o liver enzymes (ALT and AST); o additional tests: bilirubin, creatinine, urinalysis, glucose; o testing for TB, hepatitis B and C (if at risk); o pregnancy tests for adolescent girls. Other evaluations to be undertaken during the visit: • anthropometrical measurements: weight, height/length and head circumference; • nutritional assessment, including: o types of foods consumed and estimated amounts; o appetite and length of eating time; o problems associated with food intake; o identification of caregiver who feeds the child. • social assessment: o general household hygiene and access to safe water; o availability of a secure refrigerator for medication storage; o the ability of family members and other caregivers to monitor adherence; and • psychological status of both caregiver and child and a cognitive assessment of the child. 2. Nutritional support Nutritional support should include early efforts to ensure adequate nutrient intake, based on locally available and affordable foods and the provision of micronutrients equivalent to the recommended daily allowance (RDA) (16, 17). • Increasing the energy intake of asymptomatic infants and children by 10% of the RDA for their age and sex is recommended. • The energy intake of infants and children who are symptomatic or recovering from acute infec- tions should be increased by 20–30% of the RDA (18). • Such requirements are minimal and may need to be augmented for children with nutritional deficiencies (19). 398 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION • It is not necessary to increase protein intake beyond that required for a normally balanced diet (12–15% of the total energy intake) (18). • Vitamin A supplements should be given according to the WHO recommended high-dose pre- vention schedule for children at high risk2 for deficiency (20–22). • Clinical observations indicated that infants with AIDS defining clinical disease commonly have temporary lactose intolerance and cow’s milk protein (CMP) intolerance. Experts usually rec- ommend that if the child presents with severe diarrhoea, special milk formulae and lactose CMP free milk, if available, can alleviate the problem. 3. Counselling caregivers Parents and/or other caregivers of HIV-infected children should be counselled on several matters prior to starting children on ART. Adherence to ART is the key to successful treatment. It predicts and influences the virological and clinical response to treatment (23), and its importance must be communicated to caregivers. The aims of such counselling should include: • establishing trust with the caregiver and setting mutually acceptable goals for care; • obtaining explicit agreement of the child’s need for treatment and treatment adherence; • identifying and addressing any of the caregiver’s psychological issues that may decrease adher- ence; • identifying a back-up caregiver who can help with adherence support; • educating the patient and/or caregiver about the critical importance of maintaining at least 95% adherence, the link between partial adherence and resistance, and the way that temporary non- adherence can permanently limit choices; • providing information about possible side-effects of ARVs and their management; • emphasizing the need for follow-up visits and scheduling them; and, • psychological and social issues should be discussed with caregivers and appropriate referrals should be offered, including: o social and rights based services; o peer support groups for parents/caregivers and for children. Proper nutrition is also a prime counselling issue, including the optimal use of local foods, appropri- ate nutrition supplements and the nutritional management of HIV-related conditions affecting the appetite and the ability to eat (see section III.2 above). Parents should be aware of developmental milestones and stages of growth that infants and young children should be reaching and the importance for these to be observed and discussed with the physician (see sections III.5.6 and III.5.7). Prevention of infections should also be addressed, including Pneumocystis jirovecii pneumonia (PCP) prophylaxis (see section IV.3 below) and routine immunizations (see Protocol 12, Immuniza- tion of people living with HIV and people at risk for HIV infection). 3.1. Considerations of adolescent needs Once a child reaches adolescence there are other considerations that need to be taken into account and addressed during counselling to ensure that appropriate treatment and care continue to be pro- vided. During this time they pass through physical, psychological and sexual maturation, all which have implications in the continuum of their treatment and care. The following issues now need to be dscussed with and understood by the adolescent: • disclosure of the HIV status to the adolescent if it had not already been done, this should include basic information related to HIV/AIDS; • prevention strategies in light of impending sexual activity and fertility, including information on sexual and reproductive health and PMTCT (refer to protocols 9, Support for sexual and 2 Children with severe infections or severe protien-energy malnutrition. 399 Paediatric HiV/aidS treatment and care reproductive health in people living with HIV, and 10, Prevention of HIV transmission from HIV infected mothers to their infants; • prevention of opportunistic infections and the need to treat them in an expedient manner; • transition from paediatric to adult care, and that there may now be a change in health care pro- viders as well as in ARV regimens; • the importance of continuing to adhere to treatment and consequences of non-adherence; • toxicity and signs of it; and • ways to address possible stigma and discrimination. 4. ART in infants and children The critical issue in clinically managing HIV-infected children is when to initiate lifelong ART. The effectiveness of HAART in reducing HIV-related morbidity and mortality in infants and children is comparable to that observed in adults (24). However, there are unique considerations for HIV- infected infants and children, including: • exposure to ZDV and NVP (25–27) and other ARVs taken during pregnancy, which may result in ARV resistance; • age-dependent differences in immunological markers (e.g. CD4 percentage is used for children, not CD4 count); • age-dependent pharmacokinetical differences; • difficulties adhering to long-term combination treatment; • difficulties taking medication during sleeping hours or at school; and • unwillingness of children and adolescents to take medication. Children should be started on ART when they have either an AIDS-defining illness or severe im- munological failure (see Table 1). The decision to start ART should be made according to both CD4 percentage and age. It is now possible to determine the exact risk of progression to AIDS or death over the next calendar year based on these factors (a risk calculator is available from the HIV Paediatric Prognostic Markers Collaborative Study (28)). Infants who are at high risk for clinical progression, particularly for HIV encephalopathy, should start ART with a higher CD4 percentage than older children. Initiation of ART in children with a confirmed HIV diagnosis should be based on the WHO guidelines for clinical staging of paediatric HIV/AIDS (see Annex 1), immunological criteria and the Paediatric European Network for Treatment of AIDS (PENTA) guidelines3 (29). Table 1. criteria for initiation of art in infants and children WHO clinical paediatric stage Age-specific treatment recommendations <12 monthsa ≥12 months 1 Treat all CD4-guided treatmentb 2 Treat all CD4-guided treatmentb 3 Treat all CD4-guided treatmentb 4c Treat all a The recommendation to treat all children <12 months differs from WHO global guidelines. European paediatric HIV experts generally believe that all infants diagnosed with HIV infection in the first year life should be treated, however, additional re- search is in need to confirm this recommendation. b For CD4 guidance, refer to Table 2. c Stabilize any opportunistic infection prior to initiating of ARV treatment. Source: adapted from global guidelines, WHO (30). 3 Wherever possible, children with HIV in Europe should be cared for in collaboration with a member of the PENTA network. Full contact details are at http://www.ctu.mrc.ac.uk/penta. 400 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 4.1. Immunological, age-specific criteria for initiation of ART • Immunological markers supplement clinical assessment and should therefore be used in combi- nation with clinical staging. • The threshold CD4 levels for severe immunodeficiency, as indicated in Table 2 below, are de- rived from longitudinal data on HIV-infected infants and children and indicate the levels at which ART is required. In general CD4 percentage is a more accurate marker in children aged under 5 years and CD4 count is the better guide for children aged over 5 years. • Where the CD4 percentage is not available, absolute CD4 count thresholds may be used • For children over the age of 5, the same cut-off value as in adults – i.e. 200–350 cells/mm3 – can be used. There is a marked increase in risk of AIDS when the CD4 count drops below 200, so this should be avoided. • A drop below threshold values should be avoided, as it significantly increases the risk of disease progression and mortality. ART should be initiated by these cut-off levels, regardless of clinical stage. • For children with pulmonary TB, the result of CD4 measurement and clinical status should guide whether ART is urgently required or can be delayed (refer to Protocol 4, Management of tuberculosis and HIV coinfection). See Annex 2 for an overview of the proposed revision to the immunological classification. Table 2. cd4 criteria for initiation of art Immunological marker Recommended threshold levels for initiating ART ≤11 months 12–35 months 36–59 months ≥5 yearsa CD4 % and/or CD4 count ≤25% (≤1500 cells/mm3) ≤20% (≤750 cells/mm3) ≤15% (≤350 cells/mm3) ≤200 cells/mm3 (≤15%) a Starting at 5 years of age CD4 cell count is a more accurate indication for initiation of treatment. Source: adapted from WHO (30). HIV progression is more rapid in children than in adults. The predictive value of specific HIV RNA levels for disease progression is difficult to interpret, particularly for infants, so an assessment of viral load (VL) is not considered necessary before starting treatment. However, VL remains a useful measurement of treatment response and should be performed before starting ART and at one month and three months of treatment, if possible. The aim of treatment is to achieve an undetectable VL level (now usually defined as <50 copies HIV/ml plasma), which stops viral replication and reduces the chances of resistance to the ART combination being used. The risk of progression to AIDS or death within 12 months based on age, CD4% or CD4 count or viral load may be a useful as complementary information to clinical and laboratory indicators when making a decision to initiate treatment. This may be calculated by using the risk calculator that can be accessed at http://www.ctu.mrc.ac.uk/penta/hppmcs (31). 4.2. First-line HAART regimens The choice of first-line ARV regimens for infants and children follows the same principles as for adults, with several additional considerations: • the patient’s age • the suitability of drug formulations • the side-effect profile • the possibility of maintaining future treatment options • anticipated patient adherence • coexisting conditions (coinfections, malnutrition, metabolic abnormalities) • risk of pregnancy in adolescent girls • potential drug interactions. 401 Paediatric HiV/aidS treatment and care In the absence of resistance assays, children who receive ARV prophylaxis should follow the stand- ard first line ART regimens indicated in Table 3. Table 3. First-line art for infants and children Age ARV drug classes ART regimens <3 years (or <10 kg) 2 NRTIs + 1 NNRTI ABC (or ZDV) + 3TCa + NVPb ≥3 years 2 NRTIs + 1 NNRTI ABC (or ZDV) + 3TCa + EFVb, c a The ABC + 3TC combination is very effective for ART-naive children. PENTA 5 follow up data clearly confirms the superi- ority of this regimen (http://www.ctu.mrc.ac.uk/penta/trials.htm (32, 33). d4T should be avoided due to the increased risk of lipodystrophy (34, 35). b EFV is not currently recommended for children <3 years of age or <10 kg, and should not be given to post-pubertal girls who are either in the first trimester of pregnancy or are sexually active and not receiving adequate contraception. EFV is preferred over NVP in children older than three years. c NVP should be avoided in post-pubertal girls (considered adults for treatment purposes) with baseline CD4 absolute cell counts >250 cells/mm3. 4.3. HAART regimens in special circumstances The triple-NRTI regimen can be considered an alternative option that simplifies initial treatment in special circumstances. The potency of this regimen with high viral load, which is common in in- fants infected in utero is a matter of concern, as has been demonstrated in adult studies (36–38), and therefore its use is currently recommended to be considered for specific situations including to: • pregnant adolescents with CD4 counts >250 cells/mm3, for whom NVP and EFV are contrain- dicated; and • adolescents with anticipated or documented poor adherence (if regimen is available as a fixed- dose combination (FDC)). Table 4. alternative art ARV drug class ART regimen 3 NRTIs ZDV + 3TC + ABC 4.4. ART in infants exposed to ARVs There is a possibility of infants and children developing resistance to certain ARVs in utero, intra- partum or postpartum (during breastfeeding). A resistant virus can be transmitted by: • ARV-naive mothers who were infected with resistant HIV viruses; • mothers exposed to ARVs before becoming pregnant; or • mothers exposed to ARVs during pregnancy, whether for their own health or for MTCT prophy- laxis. The frequency of such transmission has not been well documented; consequently, the recommended ART regimens remain the same as for infants not exposed to ARVs. 4.4.1. Exposure through PMTCT • If NVP or 3TC has been used for PMTCT, either alone or in a two-drug regimen, a single point mutation can result that may be associated with resistance to these ARVs (39, 40). Further re- search is needed. • Children who have previously received single-dose NVP or 3TC as part of PMTCT or other ARVs should not be denied access to life-sustaining ART. • It is not yet clear whether triple-NRTI regimens offer benefits in such situations. • The standard 2 NRTIs + 1 NNRTI first-line regimen is recommended (30). 402 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 4.4.2. Continuing exposure due to maternal ART during breastfeeding • Although some ARVs (NVP, ZDV and 3TC) are known to be present in breast milk, the concen- tration and quantity ingested by infants is less than therapeutic levels (41, 42). • If a breastfeeding infant is ill enough to require ART, the administration of ARVs at standard paediatric doses should be initiated, regardless of whether the mother is receiving ART. • The standard 2 NRTIs + 1 NNRTI first-line regimen is recommended. 4.5. ARV dosage and age-dose adjustment Every three months, the ARV drug dosage should be checked and adjusted according to the child’s weight; otherwise, there is a risk of underdosing and developing resistance. Doses are calculated either on a milligram per kilogram body weight or milligram per square meter body surface basis. Standardization is important, so that non-expert personnel can safely dispense and/or check cor- rect dosages for children. It is sensible clinical practice to round up doses into easier doses for the parents. It is better to overdose by up to 10% as the child rapidly grows. For ARV dosages please refer to Annex 3 (30). 4.6. Adherence Adherence is the key to achieving an effective clinical, immunological and virological response to ART, and it should be no less than 95% of the prescribed dosage (23, 43, 44). An initial intervention strategy to improve adherence is described in section III.3 above on counselling of caregivers, and adherence monitoring is described in section III.5.5 below. Medication strategies to improve adherence include: • choosing the simplest regimen, with a lower dosing frequency and number of pills; • prescribing carefully to avoid drug interactions; • simplifying food requirements for administration of medication; • informing patients and caregivers of possible side-effects, and anticipating and treating side-ef- fects; and • using the best-tasting liquid medication if possible, and introducing tablets as soon as feasible or if liquid medication is not available. 4.7. ART failure Poor adherence, inadequate ARV dosage or potency (23, 43, 45, 46) and pharmacokinetic problems (47) can all contribute to treatment failure. Children should have been taking their first-line regi- men for at least 24 weeks and adherence deemed adequate before treatment failure is suspected. The clinical criteria for treatment failure should be supported with immunological (CD4) criteria. 4.7.1. Immunological failure In treatment failure, children on ART persist at or below the age-related CD4 threshold for initiating treatment (see Table 2 above). Failure is characterized by an initial immune recovery after initiation of ART, followed by a drop in CD4 measurements to values at or below their age-related threshold for initiation of treatment. Previous CD4 values are thus needed to define treatment failure using immunological criteria. 4.7.2. Virological failure The definition of virological treatment failure is more complex, and consensus on it has not yet been reached. The overall aim of treatment is to reduce VL to levels below the lowest detection threshold (<50 copies/ml) and to maintain it as long as possible. A large number of children on treatment, however, have a detectable VL between 1000 and 50,000 copies/ml, but continue to have excellent clinical response and maintain high CD4% values. Since no clear single virological threshold can be recognized to prompt switching to second-line ART, the final decision should be taken based upon consideration of the clinical and immunological status of the child. 403 Paediatric HiV/aidS treatment and care 4.7.3. Clinical failure The following are considered indicative of treatment failure: • development of new or recurring Stage 3 or 4 events (see Annex 1) at least 24 weeks after initia- tion of a first-line regimen; • lack of or decline in growth rate in children who show an initial response to treatment, despite adequate nutritional support and without other explanation; • loss of neuro-developmental milestones (presence of two or more of the following: impairment in brain growth, decline in cognitive function and clinical motor dysfunction (48)); and • new opportunistic infections, new malignancies, recurrence of refractory oral candidiasis or recurrence of oesophageal candidiasis. Clinical disease progression should be differentiated from immune reconstitution inflammatory syndrome (IRIS), please see section III.5.3. 4.8. Second-line ART regimens The entire regimen should be changed from a first-line to a second-line combination only in the event of immunological or clinical failure after 24 weeks of treatment. The new second-line regi- men should include at least three new drugs, one or more of them from a new class, in order to increase the likelihood of treatment success and minimize the risk of cross- resistance, and it should be based upon drugs that retain activity against the patient’s viral strain (see Table 5). The advantages of PI-based regimens include proven clinical efficacy and well-described toxicities. Because of the diminished potential of almost any second-line nucleoside component, a low-dosed RTV-enhanced PI (PI/r) component is recommended. Table 5.

Strategies in the event of second-line treatment failure Multidrug resistance in children who have received multiple antiretroviral regimens is an increas- ing problem in paediatric treatment in developed countries. Limited data are available for making recommendations about treatment options in these cases. Such decisions are complex and require consultation with an HIV specialist; refer the child and the caregiver to the tertiary-level hospital as indicated. Possible strategies include: • addition or substitution of new drugs (such as enfurvirtide/T20) • strategic recycling of drugs • structured treatment interruptions • continuation of current treatment until additional drugs become available. 404 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 5. Monitoring children with HIV Children with HIV should be monitored regularly in order to adjust case management strategy and treatment plans. Such monitoring should cover the health conditions of those not eligible for ART as well as those who are under treatment. 5.1. Routine monitoring of patients before ART The main reasons for monitoring HIV-infected children are to identify the proper time for initiation of ART, to prepare the patient and caregiver for ART and to prevent, detect and treat common HIV complications. • Clinical evaluation of infants and children not yet eligible for ART should be performed every 3–6 months. • The same parameters that were used in the baseline evaluation should continue to be monitored. All children should be plotted on a growth chart, as growth failure is one of the commonest AIDS-defining symptoms in paediatric HIV. • Clinical evaluation and CD4 measurements can be performed more frequently as the clinical or immunological threshold for initiating ART approaches (see Table 2). • Evaluation and nutritional support should be provided during each contact with children and caregivers, preferably every month. 5.2. Routine monitoring of patients on HAART Children’s responses to ART should be monitored regularly, including clinical, laboratory and ad- herence monitoring. 5.2.1. Clinical monitoring Clinical monitoring should be performed every three months, focusing on important signs of ART response, including: • growth, especially in children who have been failing to grow; • neurological symptoms and development in children who have encephalopathy or have been late in reaching developmental milestones; and • type and frequency of opportunistic infections (bacterial infections, thrush, etc.). 5.2.2. Laboratory monitoring • CD4 values should be measured every three months, or more often if clinically indicated. • Laboratory monitoring of ARV toxicity and comorbidities should largely be directed by clinical symptoms. 5.3. Immune reconstitution inflammatory syndrome IRIS has been observed in adults and less frequently in children starting ART, particularly those with very low CD4 values (49–54). Symptoms are similar to those seen in opportunistic infections. They usually occur within the first three months after the start of potent ART (55), concurrent with a rapid rise in CD4 values. It is also possible that immunological reconstitution may lead to the development of atypical presentations of some opportunistic infections. 5.4. Monitoring ARV toxicity Distinguishing complications of HIV disease from toxicity secondary to ARVs is sometimes dif- ficult. Alternative explanations for apparent ARV toxicity can include a concurrent infection (such as viral hepatitis infection in a child with hepatitis symptoms), or a reaction to a concurrent non- 405 Paediatric HiV/aidS treatment and care ARV drug (such as isoniazid-induced hepatitis in a child on TB treatment or cotrimoxazole-induced rash in a child receiving preventive therapy). Such non-ARV-related adverse events do not neces- sitate a change in ARVs. Drug-related adverse events may be acute (occurring soon after the drug is administered), subacute (occurring within one or two days) or late (occurring after prolonged administration).4 Most toxicities are less common in children than in adults (for example, NVP-related symptomatic hepatotoxicity is rare in children). Adverse events can vary in severity from mild to severe and life- threatening. Take the following steps when managing ARV toxicity: • Determine the seriousness of the toxicity. • Establish whether toxicity is due to an ARV or a concurrent non-ARV medication. • Consider other disease processes (for example, viral hepatitis in ARV patients with jaundice), since not all problems that arise during treatment are due to ARVs. • Manage the adverse event according to its severity. ° In case of severe life-threatening reactions, immediately discontinue all ARVs, manage the medical event and then reintroduce the same ARVs in a modified regimen, substituting for the offending drug when the patient stabilized. Such reactions are very rare and are usually only seen with fulminant hyperlactaemia. ° In case of severe reactions, substitute for the offending drug without stopping ART. Severe reactions are also rare, and they most commonly occur when a child develops lipoatrophy or neuropathy from prolonged d4T use. ° In case of moderate reactions, consider continuation of ART as long as feasible; if the patient does not improve on symptomatic treatment, consider single drug substitutions. ° Mild reactions may be bothersome but do not require changes in treatment. • For mild and moderate reactions, stress the importance of maintaining adherence despite toxicity. • To reiterate, if life-threatening toxicity develops, all ARVs should be stopped until the patient’s condition is stabilized. Several distinct types of adverse effects common with certain ARVs or drug classes have been identified, including: • adverse haematological events (anaemia, neutropenia and, more rarely, thrombocytopenia) from drug-induced bone-marrow suppression, most commonly due to ZDV treatment; • mitochondrial dysfunction, primarily seen with the NRTI drugs, including lactic acidosis, he- patic toxicity, pancreatitis and peripheral neuropathy;5 • lipodystrophy and metabolic abnormalities, primarily seen with d4T and ritonavir-boosted PIs, as well as with certain other NRTIs;6 and • allergic reactions such as skin rashes and hypersensitivity reactions, more common with the NNRTIs but also seen with certain NRTIs, such as ABC. 4 Brief details of toxicity for specific drugs can be found on the Children’s HIV Association web site (http://www.bhiva.org/ chiva) under the relevant name. 5 NRTIs differ in their ability to affect mitochondrial function, with d4T having greater toxicity than ZDV, and 3TC or ABC having less. 6 Abnormalities include fat maldistribution, particularly peripheral lipoatrophy associated with d4T and ZDV, and body habitus changes; hyperlipidaemia; hyperglycaemia, insulin resistance and diabetes mellitus; and osteopenia, osteoporosis and osteo- necrosis. 406 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 5.4.1. Clinical signs of ARV toxicity and its management Table 6. Signs of arV toxicity and its management Clinical manifestations Laboratory abnormalities Toxicity management Acute serious adverse reactions Acute symptomatic hepatitis (NNRTIs – particularly NVP, more rarely EFV – NRTIs and PIs) Jaundice Liver enlargement Gastrointestinal symptoms Fatigue, anorexia Hypersensitivity (rash, fever, sys- temic symptoms), usually within 6–8 weeks Lactic acidosis (see below) if sec- ondary to an NRTI Elevated aminotransferase levels Elevated bilirubin Discontinue all ARVs until symptoms resolve. Monitor aminotransferase and bilirubin levels. If the patient is on NVP, it should be dis- continued and not re-administered. Once symptoms resolve, either: • change to an alternative ARV (required for NVP regimens); or • restart the ART regimen with close observation; if symptoms recur, substi- tute an alternative ARV (see Table 7). Acute pancreatitis (NRTIs, particularly d4T and ddI, more rarely 3TC) Severe nausea and vomiting Severe abdominal pain Lactic acidosis (see below) Elevated pancreatic amylase Elevated lipase Discontinue all ARVs until symptoms resolve. Monitor serum pancreatic amylase and lipase. Once symptoms resolve, restart ART with an alternative NRTI, preferably without pancreatic toxicity (see Table 7). Hypersensitivity reaction (ABC, NVP) ABC: acute onset of respiratory and gastrointestinal symptoms, includ- ing fever, fatigue, myalgia, nausea, vomiting, diarrhoea, abdominal pain, pharyngitis, cough, dyspnoea; rash (usually mild); progressive worsen- ing of symptoms soon after receiv- ing ABC dose, usually within 6–8 weeks NVP: systemic symptoms of fever, myalgia, arthralgia, hepatitis, with or without rashc Elevated aminotransferase levels Elevated eosinophil count Immediately discontinue all ARVs until symptoms resolve. NVP and ABC should not be re-adminis- tered to the patient in future. Once symptoms resolve, restart ART with an alternative ARV for ABC or NVP (see Table 7). Lactic acidosis (NRTIs, particularly d4T) Generalized fatigue and weakness Gastrointestinal symptoms (nausea, vomiting, diarrhoea, abdominal pain, hepatomegaly, anorexia and/or sudden unexplained weight loss) Hepatitis or pancreatitis (see above) Respiratory features (tachypnoea and dyspnoea) Neurological symptoms (including motor weakness) Increased anion gap Lactic acidosis (symptoms may continue or worsen despite dis- continuing ART) Elevated aminotransferase levels Elevated CPK Elevated LDH Discontinue all ARVs until symptoms resolve. Once symptoms resolve, restart ART with an alternative NRTI that has lower mitochon- drial toxicity risk (e.g. ABC or ZDV) (see Table 7). 407 Paediatric HiV/aidS treatment and care Clinical manifestations Laboratory abnormalities Toxicity management Severe rash/Stevens–Johnson syndrome (NNRTIs, particularly NVP, less commonly EFV) Rash during first 6–8 weeks Mild-to-moderate rash: erythema- tous, maculopapular, confluent, most often on the body and arms; no systemic symptoms Severe rash: extensive rash with moist desquamation, angio-oedema or serum sickness-like reaction; or a rash with constitutional findings such as fever, oral lesions, blistering, facial oedema, conjunctivitis Life-threatening Stevens–Johnson syndrome or toxic epidermal necrolysis Elevated aminotransferase levels For mild or moderate rash, continue ART without interruption but under close obser- vation. For severe or life-threatening rash, discon- tinue all ARVs until symptoms resolve. NVP should not be readministered to the patient. Once symptoms resolve, restart ART with an alternative ARV for NVP (see Table 7 below). (Note: most experts would not change to another NNRTI if the patient experienced severe or life-threatening Ste- vens–Johnson syndrome from NVP.) Severe life-threatening anaemia (ZDV) Severe pallor, tachycardia Significant fatigue Congestive heart failure Low haemoglobin If refractory to symptomatic treatment (e.g. transfusion), discontinue ZDV only and substitute another NRTI (see Table 7 below). Severe neutropenia (ZDV) Sepsis/infection Low neutrophil count If refractory to symptomatic treatment (e.g. transfusion), discontinue ZDV only and substitute another NRTI (see Table 7 below). Chronic late serious adverse reactions Lipodystrophy/metabolic syndrome (d4T, PIs) Fat accumulation and/or loss in distinct regions of the body: • increased fat around the abdo- men, buffalo hump, breast hypertrophy; and • fat loss from limbs, buttocks and face Insulin resistance, including diabetes mellitus Potential risk for later coronary artery disease Hypertriglyceridaemia Hypercholesterolaemia Low HDL levels Hyperglycaemia Do not prescribe d4T. Substitution of an NNRTI for a PI may decrease serum lipid abnormalities. Severe peripheral neuropathy (d4T, ddI; more rarely 3TC) Pain, tingling, numbness of hands or feet; refusal to walk Distal sensory loss Mild muscle weakness and areflexia None Stop only the suspected NRTI and substi- tute an NRTI not associated with neurotox- icity (see Table 7). Symptoms may take several weeks to resolve. Source: WHO (30) 5.4.2. ARV substitution in first-line regimens due to toxicity Given the limited number of ARV options, drug substitutions should be limited to situations where toxicity is severe or life-threatening (see Table 6). Substitution with PIs because of toxicity should be avoided if possible. 408 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Table 7. arV substitution options in first-line art First-line ARV Most frequent significant toxicities Suggested first-line ARV drug substitution ABC Hypersensitivity reaction ZDV ZDV Severe anaemia or neutropeniaa ABC Lactic acidosis ABC Severe gastrointestinal intoleranceb ABC EFV Persistent and severe central nervous system toxicityc NVP Teratogenicity (avoid in adolescent girls in first-trimester pregnancy or who have childbearing potential but do not receive adequate contracep- tion) NVP Acute symptomatic hepatitisd EFVe Hypersensitivity reaction NRTI substitution preferred, giving a triple NRTI (Note: may be less potent); or PI substitution (Note: premature start of sec- ond-line ARV) Severe or life-thr eatening rash (Stevens–Johnson syndrome)f a Defined as a severe, possibly life-threatening haematological abnormality that is refractory to supportive therapy. b Defined as a severe, refractory gastrointestinal intolerance that prevents ingestion of the ARV regimen. c Defined as severe central nervous system toxicity such as persistent hallucinations or psychosis. d Symptomatic NVP-associated hepatic toxicity is very rare in HIV-infected children prior to adolescence. e EFV is not currently recommended for children <3 years of age or <10 kg, and should not be given to post-pubertal adolescent girls who are either in the first trimester of pregnancy or are sexually active without adequate contraception. f Severe rash is defined either as an extensive rash with desquamation, angio-oedema or serum sickness-like reactions, or a rash with constitutional findings such as fever, oral lesions, blistering, facial oedema or conjunctivitis. Stevens–Johnson syndrome can be life-threatening. For life-threatening rash, most clinicians would not substitute EFV due to the possibility of NNRTI- class toxicity. 5.5. Monitoring adherence As there is evidence that adherence to HAART predicts the virological and clinical response to treatment (23, 43, 44), monitoring it is essential. Monitoring adherence should be seen as a team responsibility of the patient, caregiver and health care workers. Intervention strategies include: • It is important to monitor and assess adherence at each visit, for example by using a simple questionnaire, and between visits by telephone or letter as needed • using pill boxes, reminders, alarms, pagers or timers • using patient education aids, including pictures and calendars • patient support groups or one-on-one counselling • directly observed treatment (DOT) • adherence checklist for caregivers • discussing potential adherence constraints with caregivers When children are 8–10 years old at diagnosis, adherence may improve in contrast to younger chil- dren. The age, maturity and social circumstances of the children should be taken into consideration, and communication should occur in a language and at a level they can understand. Children’s support groups can be helpful, in which children come to the hospital and play (educa- tional) games together. They learn they are not the only ones with HIV, while their caregivers also have the opportunity to talk with each other. 409 Paediatric HiV/aidS treatment and care 5.6. Nutritional and growth monitoring Systematic evaluation of nutritional status and related symptoms is critical to early identifica- tion of malnutrition and poor growth, and it should be part of routine clinical monitoring of HIV-infected infants and children. • For infants, nutritional evaluation should occur monthly and other children every three months, and includes: ° mode of feeding7 ° frequency, duration or quantity taken ° adequacy of supply ° bowel and urine habits ° reported problems (56). • Children should be measured and weighed at each visit assessment: ° use the same scale at each visit ° measure length of babies supine ° measure length of children >2 years standing ° measure head circumference to obtain greatest ° gender and age specificity should be taken into consideration ° plot growth parameters on chart. • If the child requires particular attention due to growth problems or special nutritional require ments it should be performed more often (56). 5.7. Developmental assessment It is important to assess and continue to monitor the development of cognitive, motor, language and social skills of infants and young children as a significant proportion of them show early and marked delays in these areas that may be important early indicators of HIV disease progression (57, 58). • A developmental assessment should be conducted at each visit. • The assessment should include cognitive, motor, language and social skills. • Discuss the infant’s milestones and verify that the child is developing appropriately for age. • Use the developmental chick list or observe the infant during the examination (see Annex 4) (56). The primary aim is early detection of developmental weaknesses in order to facilitate intervention to prevent and/or reduce the impact of severe problems. 7 The WHO Regional Office for Europe recommends infant formulae feeding; when this is not available exclusive breast- feeding is an alternative. 410 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION IV. Prevention and management of major opportunistic infections The optimal management of children with HIV infection requires attending to more than just ART. Children with very low CD4 counts for their age are the most at risk for OIs. When considering prophylactic treatment in a newly presenting and severely immunosuppressed child, the first prior- ity is to start effective ART to restore the immune response. For children who have failed multiple ART regimes and have very low CD4 counts, whether or not they are currently on ART, appropriate OI prophylaxis is extremely important.8 1. Tuberculosis Tuberculosis (TB) represents a significant threat to child health, and HIV infection increases sus- ceptibility to infection with M. tuberculosis and the risk of rapid progression to TB disease. Please refer to Protocol 4, Management of tuberculosis and HIV coinfection, for recommendations re- garding identification of TB/HIV in infants and children, and clinical management of TB/HIV in children. 2. Disseminated mycobaceteriosis other than TB (DMOT) DMOT is associated with severe immunosuppression and a CD4 count <50 cells/mm3. Ninety per cent of cases are due to Mycobacterium avium complex (MAC). Median survival for children is six months from diagnosis. Such cases should be discussed with an HIV paediatrician. 2.1. Prophylaxis DMOT can be prevented by giving all children with a CD4 count <50 azithromycin 20 mg/kg as a single weekly dose (to a maximum of 600 mg). 2.2. Diagnosis Clinical features usually include prolonged fever, bone marrow suppression, weight loss and chron- ic gastrointestinal symptoms. In patients with DMOT, MAC may be isolated from the lungs, or acid-fast bacilli (AFB) may be detected in the stools or bone marrow. Radiological presentation can occur as enlarged hilar lymph nodes. 2.3. Treatment Treatment involves a complex multidrug regime of ciprofloxacin, rifabutin and clarithromycin and is valid for all ages. Rifabutin is not available in a liquid formulation, but a suspension (10 mg/ml in cherry or simple syrup) can be formulated from the contents of capsules (60). If the clinical presentation is suspected then mycobacterial blood cultures should be taken using the special bottles available from microbiology. Mycobacterial stool cultures should also be taken. Treatment for DMOT is shown in Table 8. Table 8. treatment of dmOt Antimicrobial Agent Dose Frequency Route Duration ciprofloxacin + rifabutin + clarithromycin* 30 mg/kg 10–20 mg/kg 7.5 mg/kg BID (twice daily) (max dose 750 mg) OD (once daily) (max dose 300 mg/day) BID (max dose 500 mg) PO (orally) PO PO 6 months * If clarithromycin is not available, it can be substituted with ethambutol, 15 mg/kg OD, PO. 8 Much of this section is based on or taken directly from Treating Opportunistic Infections In HIV-Infected Children Guidelines for the Children’s HIV Association (CHIVA) (59), with the permission of the authors and CHIVA. More details of the preven- tion and management of opportunistic infections in infants and children can be found on the Children’s HIV Association web- site (http://www.bhiva.org/chiva/protocols/supportdocs/CHIVA-presubmissionAug06.pdf). 411 Paediatric HiV/aidS treatment and care Be aware of possible complex drug interactions, especially with rifabutin. For possible drug interac- tions and management strategies please refer to www.druginteraction.org. 3. Pneumocystis jirovecii pneumonia PCP is one of the most common categories of HIV-associated OIs, occurring in about 40–50% of children reported to have HIV infection. It has also been identified as the leading cause of death in infants with HIV infection and accounts for 50–60% of AIDS diagnoses in infants (61, 62). PCP is most common in children under one year old (72% of children presenting with PCP) (63), for whom chemoprophylaxis of PCP is recommended. 3.1. Prophylaxis Prophylaxis with cotrimoxazole (trimethoprim-sulfamethoxazole, or TMP-SMZ) (see Table 9 ) is recommended for: • all HIV-exposed infants, starting at 4–6 weeks of age and continuing until HIV infection can be excluded by virological testing (younger than 18 months of age in non-breastfeeding infants) or serological testing (18 months and older); and • all children under one year old with documented HIV infection, regardless of symptoms or CD4 percentage. Once initiated, prophylaxis should be continued until age 5, when discontinuing may be considered in accordance with the recommendations for adults and adolescents. Table 9. cotrimoxazole (tmP-SmZ) formulations and dosage for HiV-infected Recommended once-daily dosagea Suspension (5 ml syrup, 40/200 mg) Paediatric tablet (20/100 mg) Single-strength adult tablet (80/400 mg) Double-strength adult tablet (160/800 mg) <6 months 20/100 mg 2.5 ml 1 tablet ¼ tablet, possibly mixed with feedingb – 6 months–5 years 40/200 mg 5 mlc 2 tablets ½ tablet – 6–14 years 80/400 mg 10 mlc 4 tablets 1 tablet ½ tablet >14 years 160/800 mg – – 2 tablets 1 tablet a Some countries may use weight bands to determine dosage. The following table is from the CHAP trial: Age Weight <6 months <5 kg 6 months–5 years 5–15 kg 6–14 years 15–30 kg >14 years >30 kg b Splitting tablets into quarters is not considered best practice. It should be done only if syrups are not available. c Children of these ages (6 months–14 years) may be able to swallow crushed tablets. Source: adapted from WHO (64, 65). After successfully treating an acute episode of PCP, it is necessary to continue secondary prophy- laxis with cotrimoxazole on a long-term basis to prevent recurrence. It may be discontinued when the patient’s CD4 count remains stable for at least three months. 412 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 3.2. Diagnosis The clinical features of PCP are tachypnoea, dyspnoea, cough, hypoxia and low-grade fever. The onset may be insidious over one or two weeks with slowly increasing tachypnoea. Coughing is not usually prominent until the full clinical picture develops with severe dyspnoea. Physical findings are usually limited to fine crepitations. Fever is often low grade. A rapidly progressive course of disease leading to respiratory failure in a few days has also been described. The classic chest X- ray may be normal or hyperinflated early in the disease, but there is usually rapid development of complete opacification with air bronchograms. The alveolar infiltrates progress peripherally with late apical sparing and small pleural effusions reported. Occasionally bullae, cysts or pneumothorax may be seen. In infants, bronchoscopy with bronchoalveolar lavage (BAL) is now the optimal method for di- agnosing PCP. BAL can be done using an 8F nasogastric feeding tube in intubated children who may not tolerate bronchoscopy. If BAL cannot be performed immediately, then start cotrimoxazole treatment first (positive results can be obtained up to 48 hours after starting treatment). The micro- biology laboratory should be informed prior to BAL, as it is very important to make a definitive diagnosis even after commencing treatment. 3.3. Treatment See Table 9 above for the recommended initial treatment of PCP. • After the acute pneumonitis has resolved, children with mild-to-moderate disease who do not have malabsorption or diarrhoea can receive treatment with the dose of TMP-SMZ 60 mg/kg every 12 hours, IV, once the child is on oral feeding (around the second week of treatment) ad- minister treatment PO for a total of a 21-day course. • If there is failure to respond to cotrimoxazole, or an allergic reaction, second-line treatment should be undertaken (see Table 10). • In case of failure to respond to cotrimoxazole, repeated BAL or lung biopsy should be consid- ered. • Cytomegalovirus (CMV) is frequently found in BAL with PCP infection, but ganciclovir should only be used for children with PCP and CMV if they are not responding to standard PCP therapy. • In case of a moderate and severe PCP, oral prednisolone might be an option: 2mg/kg 1 week, 1 mg/kg 1 week, 0.5mg/kg 1 week. Table 10. Second-line treatment Antimicrobial agenta Dose Frequency Route Duration pentamidine isethionate 4 mg/kg/day OD Pentamidine isethi- onate slow infusion IV for 14–21 days 14–21 days or: dapsone 2 mg/kg (max. 100 mg) OD PO 21 days a Atovoquone or clindamycin might also be a choice, however only limited data exists regarding its use in children. 4. Bacterial infections (non-mycobacterial) Serious bacterial infections are very common among HIV-positive children. The frequency of bac- terial infection increases with HIV disease progression and immunosuppression. The commonest organisms are encapsulated Streptococcus pneumoniae and Haemophilus influenzae. Staphylococ- cus aureus and gram-negative infections, especially Pseudomonas aeruginosa, are seen more com- monly in children with severe HIV infection (63). 413 Paediatric HiV/aidS treatment and care 4.1. Diagnosis The clinical presentation of acute bacterial pneumonia in children with early HIV infection is similar to that in non-infected children: the commonest clinically diagnosed infection is acute pneumonia and primary septicaemia. The clinical signs may be less obvious in children with HIV. It is always important to obtain blood cultures. Ear infections and throat infections are very common. Sinusitis should be particularly sought for, either by clinical signs or sinus X-rays. 4.2. Treatment A child with clinical evidence of an acute lower respiratory tract infection (fever, cough, raised respiratory rate, chest signs or CXR changes) should be treated promptly and empirically with broad-spectrum antibiotics (oral co-amoxiclav or IV ceftriaxone). The choice of oral or intravenous antibiotics depends on the patient’s clinical condition. If there is a poor response to treatment add azithromycin (10 mg/kg OD for 5 days) and consider BAL. Generally, treatment regimes should be long (10–14 days). 5. Toxoplasmosis Toxoplasma encephalitis should be considered in all HIV-infected children with new neurologic findings. Although focal findings are more typical, the initial presentation can be variable and re- flect diffuse central nervous system (CNS) disease. 5.1. Prophylaxis PCP prophylaxis also provides prophylaxis against toxoplasmosis. Atovoquone may also provide protection. Severely immunosuppressed children (with CD4 cell count <100/mm3) who are not receiving TMP-SMZ or atovoquone and are found to be seropositive for Toxoplasma should be administered prophylaxis for both PCP and toxoplasmosis (i.e. dapsone plus pyrimethamine) (see Table 11). Indication for prophylaxis prevention in Table 11 is IgG antibody-positive for Toxoplasma and se- vere immunosuppression (CD4 <15%). Table 11.

Diagnosis A presumptive diagnosis of Toxoplasma encephalitis is based on clinical symptoms, serologic ev- idence of infection, and the presence of a space-occupying lesion on imaging studies. Clinical symptoms include motor and speech disturbances, often accompanied by headache, altered mental status, and fever. Children can also present with seizures, cranial nerve abnormalities, visual field defects, sensory disturbances, cerebellar dysfunction, meningismus and movement disorders (66). Manifestations of extracerebral toxoplasmosis in HIV-infected children include ocular toxoplasmo- sis, which occurs most often in association with Toxoplasma encephalitis necessitating neurologic examination. Patients with chorioretinitis present with blurred vision, pain or photophobia (67). Children who are infected latently with Toxoplasma gondii have variable IgG titres and rarely pos- sess IgM antibody. Although seroconversion and fourfold increase in IgG antibody titers may occur, the ability to diagnose active disease is commonly impaired by immunosuppression. IgM antibod- ies typically disappear a few months after infection but can remain elevated for more than 1 year confounding the differentiation of acute and remote infection (68). Additional investigations to support the diagnosis of Toxoplasma encephalitis include (where avail- able) CT scanning of the brain that might indicate multiple, bilateral, hypodense, focal ring-enhanc- ing lesions especially in the basal ganglia and cerebral corticomedullary junction in 70-80% of pa- tients (69). Magnetic resonance imaging is more sensitive and will confirm basal ganglia lesions in most patients (70). Although toxoplasmic encephalitis can occasionally cause a single brain lesion on MRI, such a finding suggests an alternative diagnosis (primarily CNS lymphoma and tubercu- loma) (71). Definitive diagnosis of Toxoplasma encephalitis requires histologic confirmation by brain biopsy, and can be considered when early neurologic deterioration is present despite empiric treatment or in children who fail to respond to anti-Toxoplasma therapy after 10–14 days. If lumbar puncture is not contraindicated, PCR of CSF should also be considered. Ocular toxoplasmosis is diagnosed on the basis of observation of characteristic retinal lesions in conjunction with serum specific antibodies. 5.3.

Fungal infections 6.1. Candidiasis 6.1.0.1. Prophylaxis Immune reconstitution with ART accompanied by a reduction in plasma HIV viraemia is the best intervention to reduce the rate of candida colonization and clinical disease (72, 73). Other useful interventions include good oral hygiene, avoidance of unnecessary antibiotics and steroids, and spe- cific antifungal medications. Continuous prophylactic anticandida therapy is rarely indicated, and may result in the emergence of resistant and refractory infections (74). Universal primary antifungal prophylaxis is therefore not currently recommended and the indications for secondary prophylaxis should be individualized. 6.1.1. Oropharyngeal candidiasis (OPC) 6.1.1.1. Diagnosis OPC has variable clinical manifestations: pseudomembranous (thrush), erythematous (atrophic), hyperplastic (hypertrophic) and angular cheilitis. Thrush is the most classic form of oral candidiasis, appearing as creamy white curd-like patches with inflamed underlying mucosae that are exposed after removal of the exudates. It can be found on the oropharyngeal mucosae, palate and tonsils. Erythematous OPC manifests as flat erythematous lesions on the mucosal surface. Hyperplastic candidiasis is composed of raised white plaques appearing on the lower surface of the tongue, pal- ate and buccal mucosa and cannot be removed. Angular cheilitis occurs as red, fissured lesions in the corners of the mouth. Diagnosis of oral candidiasis can be made by a KOH preparation and culture with microscopic demonstration of budding yeast cells in wet mounts or biopsy specimens. For recurrent or refractory OPC, cultures with in vitro susceptibility testing can be used to guide antifungal treatment (75). 6.1.1.2.

Oesophageal candidiasis 6.1.2.1. Diagnosis This condition can present with odynophagia, dysphagia or retrosternal pain, which can be severe enough to cause dehydration and weight loss in children. Although oropharyngeal candidiasis is common, evidence of it may be absent among children with oesophageal candidiasis, particularly those receiving HAART. Unlike infected adults, a substantial number of children with the condition may experience nausea and vomiting. 416 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Oesophageal candidiasis has a classic cobblestone appearance on barium swallow. In refractory symptomatic cases, endoscopy should be performed to rule out other causes of refractory oesophag- itis (HSV, CMV, MAC and azole-resistant Candida species). Endoscopies may show anything from a few small white raised plaques to elevated confluent plaques with hyperaemia and extensive ulceration. 6.1.2.2.

Candidaemia 6.1.3.1. Diagnosis A new-onset fever in an HIV-infected child with advanced disease and a central venous catheter is the most common clinical manifestation of candidaemia. Systemic fungaemia can lead to endog- enous endophthalmitis, and ocular examination by an ophthalmologist may be warranted among children with candidaemia. Diagnosis is best made with blood cultures using lysis-centrifugation techniques (76) or automated broth-based systems (77). When fungaemia is present, retinal ex- amination for endophthalmitis, abdominal CAT or ultrasound for hepatic or renal involvement, and bone scans for clinically suspected osteomyelitis may be appropriate. 6.1.3.2. Treatment Primary prophylaxis of candidiasis in HIV-infected infants/children is not indicated.

Viral infections 7.1. Cytomegalovirus (CMV) 7.1.1. Prophylaxis Severely immunocompromised children with HIV/CMV coinfection should have a dilated retinal examination performed every 4–6 months. Prophylaxis for children has not been well established and used. Prophylaxis with oral ganciclovir or valganciclovir can be considered for HIV-infected adolescents who are CMV-seropositive with CD4 cells count of <50 cells/mm3 (see Table 16) but must be balanced with the risks of (val)ganciclovir-induced neutropenia, anaemia, conflicting reports of ef- ficacy, lack of proven survival benefit, risk for emergence of ganciclovir-resistant CMV, and cost. Neither aciclovir nor valaciclovir should be used for CMV infection. Table 16. Prophylaxis for severely immunosuppressed adolescents (78) Antimicrobial agent Dosea Frequency Route Duration Valganciclovir Maintenance phase Ganciclovir 900 mg 900 mg BID OD PO PO 21 days 3–6 months a There are presently no paediatric doses available There are no data to guide decisions concerning discontinuation of secondary prophylaxis (chronic maintenance therapy) in children with treated CMV disease, but it is reasonable to consider stop- ping when there are sustained T-cell responses to ART. 7.1.2. Diagnosis In HIV-infected children, CMV infection may be difficult to differentiate from active CMV disease. Because of transplacental transfer of antibodies from mother to child, a positive CMV antibody as- say in an infant under 12 months old is indicative of maternal infection but not necessarily infection of the infant. In a child older than 12 months, a positive CMV antibody assay indicates previous infection with CMV but not necessarily active disease. At any age, a positive CMV culture is in- dicative of infection, but not necessarily of disease. CMV disease is rare in HIV-infected children, but it does occur in children with severe immunosuppression, in whom the common clinical mani- festations include CMV retinitis (with white fluffy exudates), hepatitis and colitis. CMV can be isolated in cell cultures from peripheral blood leukocytes, body fluids and body tissues. Using centrifuge-assisted shell vial culture amplification techniques, CMV can be detected within 16–40 hours of culture inoculation. A positive blood buffy-coat culture establishes a diagnosis of CMV viraemia and increases the likelihood that CMV disease or symptoms are caused by CMV, because children with positive blood cultures are at higher risk for developing end-organ disease. Different methods have been used to detect CMV antigen or DNA directly and identify patients at risk for development of CMV disease, including detection of pp65 antigenaemia, qualitative and quantitative PCR and DNA hybridization. The DNA assays are more sensitive than buffy-coat or urine cultures for detecting CMV and can be used to identify patients at higher risk for developing clinically recognizable disease. CMV DNA detection in CSF by DNA PCR is highly sensitive for CMV disease. Quantitative DNA PCR can be used as a marker of risk for disease and to monitor response to therapy (77). 418 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 7.1.3.

Varicella-zoster virus 7.2.1. Prophylaxis Immunosuppressed HIV-infected children who are susceptible to varicella-zoster virus9 (VZV) should avoid exposure to people with chicken pox or shingles. For the prophylaxis of chicken pox, HIV-infected patients susceptible to VZV should be administered varicella-zoster immunoglobulin (VZIg) as soon as possible, ideally within 96 hours after any close contact with chicken pox or shingles. There are no data on the effectiveness of aciclovir for preventing chicken pox in HIV-infected chil- dren or adults. 7.2.2. Diagnosis The diagnosis of VZV infection is often suspected from the clinical presentation A generalized se- vere pruritic vesicular rash and fever is diagnostic. Lesions appear first and are most numerous on the trunk, neck, and face. The vesicles contain fluid, rest on an erythematous base and ulcerate and dry to form crusts and scabs. Lesions during chronic VZV infection are varicelliform at onset but may evolve into non-healing, necrotic and crusted ulcers that become hyperkeratotic (79). The classical clinical presentation of zoster (a painful localized cutaneous vesicular eruption along one or more contiguous dermatomes) is diagnostic. Lesions evolve over 1 to 2 days to form vesi- cles, pustules, and crusts. In HIV-infected patients, zoster may be bullous, haemorrhagic, necrotic, and particularly painful. Blisters and crusts usually last 2–3 weeks, although necrotic lesions may last up to 6 weeks and heal with severe scarring. Zoster in HIV-infected children may also present as an atypical rash that extends beyond dermatomal boundaries or is bilaterally distributed or gen- eralized or as multiple episodes of a disseminated rash more similar in appearance to chickenpox than zoster (80). Varicella pneumonitis in HIV-infected children is associated with severe pulmonary manifestations resulting in hypoxaemia and diffuse reticulo-nodular densities on radiography. Encephalitis oc- curs more frequently with zoster in the ophthalmic distribution, and cerebellar findings are typical; prominent symptoms include ataxia, tremors, and dizziness. Cerebral involvement results in fever, headache, vomiting and lethargy (81). Direct immunofluorescence expressed on the surface of infected cells from scrapings obtained from the base of skin, conjunctiva, or mucosal lesions allow VZV antigen detection, and is the diagnostic procedure of choice. Direct and indirect immunofluorescence or immunoperoxidase methods can also detect antigen in VZV-infected cells in tissue sections of lung, liver, brain, or other organs. 9 Susceptible patients are those who have no history of chicken pox or shingles or who have no detectable VZV antibody. 419 Paediatric HiV/aidS treatment and care 7.2.3.

Herpes simplex virus (HSV) 7.3.1. Prophylaxis HIV-infected children with severe oral recurrences (more than 3–6 severe episodes a year) or previ- ous disseminated disease may benefit from prophylaxis with oral acyclovir (82). 7.3.2. Diagnosis Neonatal HSV can appear as disseminated multi-organ disease (occurring in approximately 25% of neonates with HSV infection), localized disease of the CNS (approximately 35% of infected ne- onates) or localized disease of the skin, eyes and mouth (approximately 40% of infected neonates) (83). Vesicular rash is present in approximately 80% of children with localized skin, eye or mouth disease, but only in approximately 60% of children with CNS or disseminated disease (84, 85). Outside of the neonatal period, the most common appearance of HSV infection in children is oro- labial disease. Fever, irritability, tender submandibular lymphadenopathy and superficial, painful ulcers in the gingival and oral mucosae and perioral area characterize primary HSV gingivostoma- titis. HIV-infected children who experience primary infection when they are immunocompromised can have severe local lesions or, more rarely, disseminated HSV with visceral involvement and generalized skin lesions with primary infection. Other sites of involvement among severely immu- nocompromised HIV-infected children include the oesophagus, CNS and genitals and disseminated disease in the liver, adrenals, lungs, kidneys, spleen and brain. Among children with suspected HSV encephalitis, detection of HSV DNA by PCR is the diagnos- tic test of choice (86). CSF cultures for HSV are usually negative. Definitive diagnosis of HSV oesophagitis requires endoscopy with biopsy (histological evidence of multinucleated giant cells with intranuclear viral inclusion) and culture. 420 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 7.3.3.

IV Until the infection resolves Aciclovir therapy should not be discontinued in neonates with CNS disease unless a repeat CSF HSV DNA PCR assay is negative at day 19–21 of treatment. Because episodes of HSV disease can be treated successfully, chronic therapy with aciclovir is not required after lesions resolve. However, people with frequent or severe recurrences can be admin- istered daily suppressive treatment with oral aciclovir or valaciclovir. 421 Paediatric HiV/aidS treatment and care V. Paediatric HIV pain management 1. Background Pain in children with HIV AIDS is a multifactor, biologically complex problem associated with di- minished quality of life and increased mortality (87). Pain elimination, pain amelioration and (when appropriate) palliative administration of analgesics and sedatives are essential aspects of the care of every HIV-infected child. Despite advances in the treatment and control of HIV infection in children, pain may still compli- cate medical management and diminish quality of life for some children with advanced disease. Be- cause pain in this population is often complex, optimal management will best be achieved through the coordinated collaboration of several specialists, including anaesthesiologists, pain specialists, social workers, nursing staff and others. Patients with pain are more than five times more likely to die than those who do not report pain. Pain is also associated with lower CD4 cell percentages and more severe immunosuppression (88). 2. Pain management strategies Pain management in HIV-infected children should combine pharmacological and non-pharmaco- logical therapies. The latter include: • relaxation techniques and behaviour modification; • environmental management: play, music, scheduled medical and nursing interventions, and structured time for sleep and rest; • gentle handling and supportive positioning; • nutritional support, adequate hydration and electrolyte replacement; • optimized tissue perfusion and oxygenation; • transcutaneous electrical nerve stimulation (TENS), gentle massage, whirlpool baths and physi- cal therapy; and • electrical or needle stimulation of acupuncture meridians by HIV-knowledgeable practitioners (88, 89). 422 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION VI. Suggested minimum data to be collected at the clinical level The suggested minimum data to be collected is important in the development of key indicators on access to diagnosis and treatment and their success. Such indicators assist managers in decision making on ways to strengthen and expand these services to all who need them. The following data should be collected at each clinical facility on a regular basis (e.g. monthly, quarterly or semi-annually): • number of infants <18 months of age born to HIV-infected mothers; • number of infants <18 months of age born to HIV-infected mothers and have had PCR testing; • number of HIV diagnosed infected infants <18 months of age; • number of infants ≥18 months of age born to HIV-infected mothers • number of infants ≥18 months of age born to HIV-infected mothers and have had only serologi- cal HIV testing; • number of HIV-infected infants ≥18 months of age diagnosed only serologically; • number of HIV-infected children (<15 years old) seen for care who are eligible for HAART; • number of HIV-infected children(<15 years old) seen for care and receiving first-line HAART regimen; • number of HIV-infected children(<15 years old) on HAART changing from first-line HAART to second-line HAART; • number of HIV-infected children(<15 years old) interrupting HAART, including the reasons (e.g. death, toxicity/side effects, loss to follow-up, ARVs not available, etc.); • number of HIV-infected children who died while on HAART, including cause of death (e.g.HIV/ AIDS related mortality or non-HIV/AIDS related mortality such as accident, etc.); • number of HIV-infected children who died within first 12 months of initiating HAART; • number of death among all HIV infected children including cause of death (e.g. HIV/AIDS related mortality or non-HIV/AIDS related mortality such as accident, etc).

Introduction This protocol is based on the global WHO recommendations for vaccinating people who are HIV- infected. At the same time, it reflects the epidemiological situation and immunization programme priorities of the WHO European Region. This protocol diverts from global recommendations re- garding the use of bacille Calmette-Guérin (BCG) vaccine, oral poliovirus vaccine (OPV) and measles-containing vaccines (MCVs) including measles, mumps and rubella (MMR) vaccine. It also provides additional recommendations on the vaccines and immunoglobulins used outside the routine national immunization programmes. This protocol is designed primarily for HIV/AIDS clinicians. It is recommended as a basis for de- veloping national recommendations that take into account local epidemiological situations. 442 hIv/aIds tReatment and caRe clInIcal PRotocols foR the who euRoPean RegIon II. General principles for the immunization of PLHIV As HIV infection results in a progressive deterioration of the immune system, there has been con- cern that some vaccines could result in severe adverse events in HIV-infected individuals. Since no immunobiological product is completely safe, general recommendations for vaccinating infants, children and adults are based on: • the characteristics of immunobiological products • scientific knowledge of the principles of active and passive immunization • the epidemiology of infection • the risk and benefits of achieving optimal protection against infectious disease. Until further research can clearly define the risks and benefits, administration of certain vaccines to people living with HIV (PLHIV) should be restricted or administered with caution after a thorough risk assessment by experts in clinical and preventive medicine. The terms vaccination and immunization are often used interchangeably. Vaccination denotes the physical act of administering an immunobiological product (a vaccine or toxoid) to a person and refers to active immunization. “Immunization” is a more inclusive term denoting the process of inducing or providing immunity artificially, and it can be active or passive. General principles for vaccination of PLHIV are as follows. • Killed or inactivated vaccines do not represent a danger to immunocompromised people and generally should be administered as recommended for other people. • Live-virus or live-bacteria vaccines such as BCG, oral poliovirus, typhoid (Ty21a), varicella and yellow fever vaccines may pose a risk to HIV-infected people, who should not be given them without careful consideration of the risks and benefits, given their individual stage of HIV disease and level of immune suppression. For further information, please refer to section III below for vaccine-specific considerations and to Annex 1 for a summary of recommendations. 443 ImmunIzatIon of PeoPle lIvIng wIth hIv and PeoPle at RIsk of hIv InfectIon 1 BCG vaccine; diphtheria, tetanus and pertussis (DTP) vaccine; OPV; MMR vaccine; hepatitis B vaccine; and HiB vaccine. 2 It should be noted that the safety information on administration of certain vaccines to PLHIV is limited, and that countries are encouraged to report any encountered adverse events following immunization (AEFIs) to their pharmacovigillance or AEFI surveillance systems, keeping in mind that some AEFIs may occur with large latency in PLHIV. 3 For clinical staging, refer to Protocol 1, Patient evaluation and antiretrovital treatment for adults and adolescents, Annex 2, and Protocol 11, Paediatric HIV/AIDS treatment and care, Annex 1. III. Use of vaccines and immunoglobulins General aspects of immunogenicity of vaccines should be taken into consideration when immuniz- ing PLHIV against vaccine-preventable diseases. • Although the capacity to mount both cellular and humoral immune response starts declining after birth in HIV-infected neonates, most children still have an immune response capacity dur- ing the first two years of life. Studies of the immunogenicity of immunization programmes with recommended vaccines1 have shown satisfactory seroconversion rates in the early stages of HIV infection. Each vaccine has its own seroconversion rate, some of which can be found in this sec- tion. However, the proportion of responders decreases with progression from HIV infection to AIDS (1). • Symptomatic HIV-infected children and adults have suboptimal immunologic responses to vac- cines (1–5). The response to both live and killed antigens may decrease as the HIV disease progresses (1). However, the response to higher doses of vaccine and the persistence of antibod- ies in HIV-infected patients have not been systematically evaluated. Although higher doses or more frequent boosters may be considered for such patients, firm recommendations cannot be made at this point. Specific considerations for the safety2 and efficacy of individual vaccines and immunoglobulins include the epidemiology of the particular disease and the patient’s level of immunosuppression. The degree to which a patient is immunocompromised should be determined by a physician, using the WHO clinical staging system3 and/or age-specific CD4 counts and percentages (see Annex 2). 1. Live attenuated vaccines 1.1. BCG vaccine BCG vaccine protects children younger than 2 against disseminated and severe tuberculosis (TB), including TB meningitis and miliary TB. BCG has little or no effect in reducing the number of adult cases of pulmonary tuberculosis. It is not known if HIV infection reduces the protection conferred by BCG in children. There is some evidence that conversion to a positive tuberculin test after BCG is less frequent in HIV-infected children (6), but the significance of this finding is not clear. There have been case reports of local complications and disseminated BCG infection, even years after vaccinating HIV-infected chil- dren. However, prospective studies comparing BCG immunization in HIV-infected and uninfected infants have shown no difference in risk for complications (6). There needs to be closer monitoring for adverse events in areas of high HIV prevalence, with specific efforts to distinguish BCG infec- tion from TB (7). 444 hIv/aIds tReatment and caRe clInIcal PRotocols foR the who euRoPean RegIon Until further research can clearly define the risks and benefits of BCG vaccination, it should be re- stricted to asymptomatic children (due to its potential to cause disseminated disease) who are at high risk of tuberculosis infection (8, 9), which in turn depend on the local prevalence of TB.4 Where the risk is high, the possible benefits of BCG immunization outweigh the possible disadvantages. 1.1.1. Recommendations • Where TB incidence is low,5 BCG should not be administered to HIV-infected children, regard- less of their clinical stage or immunodeficient status. In all other areas, BCG vaccination should be restricted to HIV-positive children who are asymptomatic. Children with symptoms of HIV infection should not receive BCG vaccine. • BCG is not recommended for adolescents and adults, including those with HIV infection, be- cause it has little or no effect in reducing the number of adult cases of pulmonary tuberculosis (6). • TB preventive therapy should be strongly recommended for PLHIV thought to be infected with Mycobacterium tuberculosis and at risk of developing TB (for further information, please refer to Protocol 4, Management of tuberculosis and HIV coinfection). 1.2. Cholera vaccine (CVD 103-HgR) 1.2.1. Recommendations • Live, attenuated oral cholera vaccine (using CVD 103-HgR strain) is contraindicated in HIV- infected people due to insufficient safety data (11). • The killed WC/rBs cholera vaccine is the recommended vaccine for HIV-infected people (see section III.2.1. below for cholera vaccine WC/rBs). 1.3. Measles, mumps and rubella vaccines (MMR, MR, M and R vaccines6) HIV-infected asymptomatic children or children with signs of mild immunosuppression should routinely receive MMR and other measles-containing vaccines (MCVs), the same as non-infect- ed children. It is important to remember that immunogenicity of measles vaccine is decreased if the vaccine is administered in a period less than six months after human normal immunoglobulin (HNIg) administration. Although studies among both asymptomatic and symptomatic HIV-infected patients immunized with MMR vaccine and other MCVs have not documented any serious or unusual adverse events (1), they are not recommended for PLHIV with evidence of severe immunosuppression. The lack of a recommendation is primarily due to: • a report of a pneumonia case following measles vaccine in an individual with severe HIV-re- lated immunosuppression (12); • other evidence indicating a diminished antibody response to measles vaccination among se- verely immunocompromised people (13); and • evidence linking measles vaccine viral infection to subsequent death in at least six severely im- munocompromised people (14). 1.3.1. Recommendations • MMR and other MCVs should not be administered to PLHIV, either children or adults, who show evidence of severe immunosuppression. Severe immunosuppression is defined as CD4 <200 cells/mm3 in adults and children ≥5 years, for severe immunosuppression in children younger than 5 years, see Annex 2 (15–17). 4 It should be noted that even among countries with a generally low prevalence of TB, there may be high prevalence in given subpopulations, making a subnational policy desirable. 5 Countries in the WHO European Region with a crude notification rate of <20 per 100 000 population are defined as low- incidence (10). 6 MMR: measles, mumps and rubella; MR: measles and rubella; M: measles; R: rubella. 445 ImmunIzatIon of PeoPle lIvIng wIth hIv and PeoPle at RIsk of hIv InfectIon • MMR and other MCVs should be considered for HIV-infected patients who are asymptomatic or mildly immunosuppressed, as per the routine national schedule. • For infants with high risk of exposure to measles virus, an additional dose of single-antigen measles vaccine administered at 6–11 months of age is recommended, followed by a first dose of routine MMR or another measles-containing vaccine (MCV) at age 12 months or older (with a minimum interval of 1 month between doses). • HIV-infected symptomatic patients who are exposed to measles should receive HNIg regardless of their prior vaccination status (see section III.3.2.1 below for further information on HNIg). • Healthy susceptible close contacts of immunocompromised people (including PLHIV) should also be vaccinated. 1.4. Oral poliovirus vaccine (OPV) Although asymptomatic HIV-infected children may be vaccinated with OPV (1, 18), data show that administration of OPV to children with congenital immunodeficiency can result in severe, progres- sive neurological involvement (paralytic disease) (19–22). Therefore, inactivated poliovirus vac- cine (IPV) is recommended for both symptomatic and asymptomatic children (see section III.2.9 below for IPV). In addition, persons immunized with OPV can shed vaccine virus into their environment for up to one month, consequently, HIV-positive individuals should have limited contact with persons vac- cinated with OPV. If OPV is inadvertently administered to a household member or other close con- tact7 of an HIV-infected individual, regardless of prior immunization status, close contact between them should be avoided for one month post-vaccination. 1.4.1. Recommendation • OPV should not be administered to PLHIV, either children or adults, regardless of their immu- nodeficiency status, or to members of their household or other close contacts. 1.5. Rotavirus vaccine 1.5.1. Recommendation • Rotavirus vaccine should not be administered to children infected with HIV regardless of their immunodeficiency status, until more scientific evidence can clarify the safety and immuno- genicity profile in HIV-infected children. 1.6. Typhoid (Ty21a) vaccine While live attenuated typhoid vaccine (using the Ty21a strain) can be administered to HIV-infected asymptomatic individuals without risk as long as the CD4 cell count >200 cells/mm3, parenteral inactivated vaccine is theoretically a safer alternative (23). 1.6.1. Recommendation • Ty21a vaccine should not be administered to PLHIV, either children or adults, regardless of their immunodeficiency status. 1.7. Varicella vaccine Although a recent small study indicated no serious adverse events for 10 HIV-infected children (24), people with moderate or severe cellular immunodeficiency resulting from HIV, including those di- agnosed with AIDS, should not receive varicella vaccine. However, children with asymptomatic or mildly symptomatic HIV infection and a CD4 cell count ≥25% should receive the vaccine at 12–15 months of age or later, with a second dose 4–8 weeks after the first. Varicella vaccine should not be administered to HIV-infected children with CD4 cell count <25% because of the potential dis- semination of viral infection (23). 7 Defined as someone who risks transmitting live poliomyelitis vaccine virus to an HIV-infected person through faecal or oral contact. 446 hIv/aIds tReatment and caRe clInIcal PRotocols foR the who euRoPean RegIon HIV-infected children and adults who are susceptible to varicella-zoster virus (VZV) – including those who have no history of chickenpox (primary varicella infection), those who have shingles (recurrent infection) and those who are seronegative – should avoid exposure to people with chick- enpox or shingles. Susceptible household contacts (especially children) of PLHIV should be vaccinated with varicella vaccine if they have no history of chickenpox and are seronegative for HIV, so that they will not transmit the virus to their HIV-infected contacts that may be susceptible to VZV (14). 1.7.1 Recommendations • Varicella vaccine should not be administered to HIV-infected adults, regardless of their immu- nodeficiency status, or to HIV-infected children with moderate or severe immunosuppression. • Varicella vaccination should be restricted to children with asymptomatic or mildly symptomatic HIV infection (CD4 levels ≥25%). • Susceptible household contacts of PLHIV should be vaccinated to prevent possible transmission of VZV. 1.8. Yellow fever vaccine Yellow fever vaccine virus poses a theoretical risk of encephalitis to HIV-infected people, who should thus not be given it. Yellow fever is endemic to 33 countries in equatorial Africa and 11 countries in South America. If travel to such an area is necessary, patients should be advised on the risks, instructed in methods of avoiding mosquitoes and supplied with vaccination waiver letters by their physicians. Some travel clinics may decide whether or not to administer the vaccine on the basis of a person’s CD4 cell count. People who are known to be HIV-infected and who cannot avoid potential exposure to yellow fever virus should be offered the choice of vaccination. Vaccinees should be monitored for possible ad- verse reactions. Since vaccination may be less effective for HIV-positive people than for HIV-nega- tive people, measuring neutralizing antibody responses before travel may be considered. Family members of immunosuppressed people may also be vaccinated against yellow fever if there are no contraindications (25). 1.8.1 Recommendation • Yellow fever vaccine should not be administered to people infected with HIV, either children or adults, regardless of their immunodeficiency status, unless benefits exceed risks. 2. Killed or inactivated vaccines Killed or inactivated vaccines do not present a danger to immunocompromised people and general- ly should be administered as recommended for other people (17). Frequently, the immune response of immunocompromised people to killed and inactivated vaccine antigens is not as good as that of immunocompetent people; higher doses or more frequent boosters may be required, although even with these modifications, the immune response may be less than optimal. 2.1. Cholera vaccine (WC/rBs) A vaccine consisting of killed whole-cell Vibrio cholerae O1 combination with a recombinant B- subunit of cholera toxin (WC/rBs) has been shown to be safe even in pregnancy and during breast- feeding, and well tolerated by HIV-positive individuals. Given orally according to a two-dose schedule, 10–14 days apart induces initial protection in 86% of the vaccinees. On average, the vaccine confers 50–60% protection for at least 3 years. There have been no specific reports of WC/rBs vaccine efficacy in HIV-positive individuals pub- lished to date but a recent study conducted in Mozambique demonstrated promising results in a 447 ImmunIzatIon of PeoPle lIvIng wIth hIv and PeoPle at RIsk of hIv InfectIon population in which approximately 25% were HIV-positive. Duration of immunity is unknown in HIV-infected people. HIV-infected adults with CD4 counts <100 cells/mm3 may be expected to respond poorly to immunization, whereas those with CD4 counts >100 cells/mm3 show improved responses after two doses (26). These observations indicate a potential benefit of vaccination in those with early and moderately advanced clinical HIV disease (27). 2.1.1 Recommendations • Vaccination should be considered for selected HIV-infected people if they are due to travel to highly endemic areas, fall in one of the risk groups (long-term travellers and for those who drink untreated water, eat poorly cooked or raw seafood, or live in unsanitary conditions in disease- endemic areas). • Owing to its low efficacy and short duration of protection, use of old parenteral vaccine (based on inactivated phenol-killed whole-cell V. cholerae O1) is not recommended, although this vac- cine is still produced in some countries (28). 2.2. Diphtheria, tetanus and pertussis vaccines (DTP, DTaP, DT, TT and Td8) 2.2.1 Recommendations • For children infected with HIV, irrespective of their immune status, DTP (and DT) vaccine is indicated on the same schedule and dosage as for non-HIV-infected children, including the use of the acellular pertussis form (DTaP) for boosters or the primary series. • TT and Td vaccines can be administered to HIV-infected adults irrespective of their immune status, using the same schedule and dose as for non-HIV-infected adults (25). • Special attention should be paid to vaccinating IDUs with TT or Td to prevent tetanus where there are no needle or syringe exchange programmes. 2.3. Haemophilus influenzae type b (HiB) vaccine In general, children older than 2 years do not need HiB vaccination, due to age-dependent suscepti- bility to the disease (11). In some people the organism causes an invasive infection. The exact mode of invading the bloodstream is unknown, but previous viral or mycoplasmal infection of the upper respiratory tract may be a contributing factor. The bacteria spread via the bloodstream to distant sites in the body, the meninges in particular. HIV-infected children and adults are at increased risk for invasive HiB disease due to immunosuppression and should therefore be vaccinated. Individual patient risk for the disease and benefits from vaccination should be considered before deciding whether to vaccinate. In some settings, the incidence of HiB disease may be higher among HIV-infected adults than non-HIV-infected adults (29, 30). 2.3.1 Recommendations • Previously unvaccinated HIV-infected individuals older than 2 years who are at risk for invasive HiB should be given at least one dose of vaccine. • Immunocompromised children should be vaccinated with the same dosage and schedule as im- munocompetent children. 2.4. Hepatitis A vaccine The risk of developing symptomatic illness following hepatitis A virus (HAV) infection is directly correlated to age. In children younger than 6, HAV infection is usually asymptomatic, while symp- tomatic disease occurs more commonly among adults. Infection with HAV induces lifelong im- munity. In areas of low endemicity, hepatitis A usually occurs as single cases among people in 8 DTP: diphtheria and tetanus toxoids and pertussis vaccine; DTaP: diphtheria and tetanus toxoids and acellular pertussis vac- cine; DT: diphtheria and tetanus toxoids (for paediatric use); TT: tetanus toxoid; Td: tetanus and diphtheria toxoids (for adult use). 448 hIv/aIds tReatment and caRe clInIcal PRotocols foR the who euRoPean RegIon high-risk groups or as outbreaks involving a small number of people. In areas of high endemicity, most people are infected with HAV without symptoms during childhood. In countries of low or in- termediate endemicity, adult disease is seen more often, and hepatitis A may represent a substantial medical and economic burden. Hepatitis A vaccine is highly immunogenic. More than 95% of adults will develop protective an- tibodies within four weeks of a single dose. Among children and adolescents, more than 97% will be seropositive within a month of the first dose. In clinical trials, all recipients had protective levels of antibodies after two doses. Therefore, post-vaccination testing is not indicated. Testing methods sufficiently sensitive to detect low HAV antibody concentrations after vaccination are not approved for routine diagnostic use (14). Data concerning the long-term persistence of antibody and of immune memory are limited because the currently available vaccines have been under evaluation for less than 12 years. The need for booster doses will be determined by future surveillance studies (31). 2.4.1. Recommendations Hepatitis A vaccination (one dose with a booster 6–12 months later) is strongly recommended for people at risk for HAV infection or its complications, irrespective of their HIV or immune status. Risk groups include: • people with chronic liver disease;9 • men who have sex with men (MSM); • drug users;10 • people with clotting-factor disorders; • people with occupational risk of infection (e.g. some laboratory workers); and • people ≥1 year old from non-endemic countries who are travelling to countries with high or intermediate risk of HAV infection.11 2.5. Hepatitis B vaccine While there are no data regarding HIV-infected children and the duration of protection afforded by HBV vaccine, available data for uninfected children show that vaccine-induced antibody levels decline with time (14). Nevertheless, immune memory remains intact for more than 15 years fol- lowing immunization in both adults and children. Adults and children with normal immune status do not require booster doses, nor is routine serological testing indicated, except for children of hepa- titis B surface antigen (HBsAg)-positive mothers, who should be tested for HBsAg and hepatitis B surface antibody (HBsAb) after the third dose. If the surface antibody level is <10 mIU/ml, the entire three-vaccine series should be repeated. Testing for HBV core antibodies in these children is discouraged because passively acquired maternal antibodies may be detectable up to 24 months of age. The need for booster doses after longer intervals will continue to be assessed as additional information becomes available.12 9 Susceptible people with chronic liver disease are at increased risk of fulminant hepatitis A should they become infected. HIV- infected people with evidence of chronic hepatitis C or hepatitis B disease should be vaccinated with hepatitis A vaccine (14). 10 HAV is present in the blood at the onset of the illness and has on rare occasions been transmitted by transfusion; the virus is more easily spread in areas of poor sanitation or personal hygiene, conditions common among drug users (14, 23, 32). 11 Vaccinate 2–4 weeks before departure. Areas of high or intermediate risk include all areas of the world except Canada, the United States, western Europe and Scandinavia, Japan, New Zealand and Australia (33). 12 Only for haemodialysis patients should the need for booster doses be assessed by annual testing for antibody levels; booster doses should be provided when antibody levels go below 10 mIU/ml. 449 ImmunIzatIon of PeoPle lIvIng wIth hIv and PeoPle at RIsk of hIv InfectIon 2.5.1. Recommendations • Hepatitis B vaccination is recommended for adults at increased risk for hepatitis B virus (HBV) infection, irrespective of their HIV or immune status, including: o MSM; o heterosexuals with multiple partners, o sexually transmitted infection (STI) patients; o sex workers; o sexual partners and household contacts of HBV carriers; o IDUs; o prison inmates, both male and female; o people on haemodialysis (although the hepatitis B vaccine is less effective in them, it is recommended for all susceptible haemodialysis patients); and o health care workers.13 • Hepatitis B vaccination is recommended for all infants at birth and all children to age 18, irre- spective of their HIV or immune status. Various schedules include or exclude neonates, but all have the same effectiveness. 2.5.1.1. Recommended schedule for hepatitis B vaccination in patients infected with HIV HIV-infected patients lacking HBV infection markers or HBsAg negative markers should be vac- cinated. • Hepatitis B vaccination should start with the conventional dose (20 µg at Months 0, 1, 2 and 12 or Months 0, 1 and 6) for patients with CD4 count >500 cells/mm3. • Paediatric dosage of hepatitis B vaccine is 10 µg. • In patients with CD4 count 200–500 cells/mm3, an intensive schedule is recommended (20 µg at Months 0, 1, 2 and 12) (34). • Patients who do not respond to the first cycle should receive booster doses or a new vaccination cycle with 40 µg. • Patients with CD4 counts <200 cells/mm3 who are not on antiretroviral treatment (ART) should first receive ART. Vaccination should be deferred until a clinically significant immune reconsti- tution has been achieved, preferentially after the CD4 cell count has increased >200 cells/mm3. 2.5.1.2. Response to hepatitis B vaccination • The response to the vaccine is dependent on the CD4 count at the time of vaccination, and may be reduced in patients with a CD4 count <500 cells/mm3. • After the hepatitis B vaccination schedule has been completed, the response rate is 87% in HIV- positive patients with CD4 count >500 cells/mm3, and only 33% in patients with CD4 count 200–500 cells/mm3 (35). • Hepatitis C virus (HCV) /HIV coinfection may be associated with impaired responses to hepa- titis B vaccine, with fewer HBsAb titres after the third vaccination than in HIV monoinfection. 2.5.1.3. Recommended monitoring of HIV-infected patients after HBV vaccination • HBsAb titre should be monitored four weeks after the end of the HBV vaccination schedule, and booster vaccination or revaccination (1–3 additional doses) should be considered for patients who do not develop protective antibodies (HBsAb <10 mIU/ml). However, the immunogenicity of higher doses of vaccine is unknown, and firm recommendations on dosage cannot be made at this time (15). • People who fail to seroconvert after vaccination and remain at risk of HBV infection should be annually monitored for serological markers of HBV (HBsAg and HBcAb (hepatitis B core antibody)). 13 Risk is often highest during training periods; therefore, it is recommended that vaccination be completed during training in schools of medicine, dentistry, nursing, laboratory technology and other allied health professions (14). 450 hIv/aIds tReatment and caRe clInIcal PRotocols foR the who euRoPean RegIon • People who fail to develop detectable HBsAb after six doses should be tested for HBsAg. • People who are found to be HBsAg-positive should be counselled accordingly. • Vaccine non-responders who are HBsAg-negative should be considered susceptible to HBV infection and should be counselled regarding precautions to prevent it and the need to obtain hepatitis B immunoglobulin (HBIg) prophylaxis for any likely parenteral or sexual exposure to HBsAg-positive blood. 2.6. Influenza vaccine14 Influenza may result in serious illness and complications for people who are immunocompromised. Vaccination can result in protective antibody levels in many immunocompromised recipients (36). 2.6.1 Recommendations • Although there is currently little information regarding the frequency and severity of influenza in PLHIV (37), vaccination is recommended for all PLHIV before the annual influenza season. • The antibody response to vaccine may be low in people with advanced HIV disease; however, it has not been shown that a booster dose improves their immune response (38). 2.7. Meningococcal vaccine 2.7.1 Recommendation • Routine immunization with meningococcal vaccine containing appropriate serotypes15 is rec- ommended for all travellers, regardless of HIV status, to areas with epidemic meningococcal disease (32), and for those in high-risk groups, including people with terminal complement component deficiencies and anatomic or functional asplenia (39). 2.8. Pneumococcal vaccine Two types of pneumococcal vaccine are available: pneumococcal polysaccharide vaccine (PPV) and pneumococcal conjugate vaccine (PCV). Pneumococcal vaccine is recommended for use in people with chronic illnesses specifically associated with increased risk of pneumococcal disease or its complications, such as conditions associated with immunosuppression, including HIV infec- tion (40). 2.8.1. Pneumococcal polysaccharide vaccine (PPV) More than 80% of non-HIV-infected healthy adults who receive PPV develop antibodies to its sero- types within 2–3 weeks. Elevated antibody levels persist for at least five years in healthy adults, but fall more quickly in people with certain underlying illnesses, including HIV infection. 2.8.1.1. Recommendations • One dose of PPV should be administered routinely, irrespective of HIV and immune status, to: o everyone who is older than 65; o immunocompetent people who are older than 216 and have chronic illness (cardiovascular disease, pulmonary disease, diabetes, alcoholism, cirrhosis or cerebrospinal fluid leaks); and o immunocompromised people (including PLHIV)17 who are older than 2 and are at risk for pneumococcal disease. 14 Since live influenza vaccine is contraindicated in PLHIV, inactivated influenza vaccine should be used. 15 The meningococcal vaccine should cover serotypes causing meningococcal disease epidemics in the relevant geographical area. Meningococcal serogroups A, B and C are found worldwide; serogroup Y is found in some parts of the United States; serogroup A is found in the “African meningitis belt” from Senegal to Ethiopia; serogroup W125 is found in Saudi Arabia. 16 In children <2 years old, antibody response with PPV to most serotypes is generally poor. 17 Including (in addition to PLHIV) people with splenic dysfunction or absence (from either disease or surgical removal), Hodgkin disease, lymphoma, multiple myeloma, chronic renal failure, nephritic syndrome (a type of kidney failure) or other conditions associated with immunosuppression (such as organ transplantation). 451 ImmunIzatIon of PeoPle lIvIng wIth hIv and PeoPle at RIsk of hIv InfectIon • PPV is recommended in HIV-infected adults with CD4 count of >200 cells/mm3 and are stable on HAART. • When CD4 count is <200 cells/mm3 vaccination may be considered for those with an increased risk for the disease; however, it may be less effective as immune response is decreased. Once HAART has been administered and immune function restored so that CD4 count increases to >200 cells/mm3, revaccination should be considered. • If vaccination status is unknown, patients with HIV infection and others with immunosuppres- sion (including those receiving long-term systemic corticosteroids) should be vaccinated (41). • Routine revaccination of immunocompetent people younger than 65 is not recommended. • People 65 and older should be given a second dose if they received the vaccine more than five years previously and were younger than 65 at the time. PLHIV and others who are immunocom- promised and at highest risk should be given a second dose after five years. • Revaccination is also recommended for children vaccinated at age 2 or older who are at highest risk for serious infection, and for those with certain underlying illnesses that make them likely to experience a rapid decline in pneumococcal antibody levels. The second dose should be ad- ministered 3–5 years after the first, though there is no upper time limit for revaccination after 5 years. 2.8.2. Pneumococcal conjugate vaccine (PCV) PCV has been shown to be immunogenic in infants and children, including those with HIV infec- tion, regardless of immune status. After four doses of PCV, virtually all healthy infants develop antibodies to all serotypes in the vaccine.18 2.6.2.1 Recommendations • For infants, doses are routinely given at 2, 4 and 6 months of age, and a booster dose is recom- mended at 12–15 months of age. • Unvaccinated children 7–11 months old, including those with HIV, should receive two doses of PCV 6–8 weeks apart, followed by a booster at age 12–15 months. • Unvaccinated children 12–23 months old should receive two doses of PCV, 6–8 weeks apart. • Unvaccinated healthy children 24–59 months old should receive a single dose of PCV. • Children 24–59 months old with HIV infection, sickle cell disease, asplenia, chronic illness or immunocompromising conditions should receive two doses of PCV 6–8 weeks apart. In order to improve the booster effect, one dose of PPV 6–8 weeks after the last PCV dose is recom- mended. • PCV is not routinely recommended for children older than 5, regardless of HIV status. • Revaccination after an age-appropriate primary series with PCV is not currently recommend- ed. • Children 2 and older who receive a primary series of PCV should also have PPV 6–8 weeks after the last dose of PCV. 2.9. Inactivated poliovirus vaccine (IPV) 2.9.1 Recommendations • In order to prevent transmission of vaccine and/or vaccine-derived polioviruses to PLHIV IPV should be administered to the following people when polio immunization is indicated: o infants and children infected with HIV regardless of their immune status; o household members or other close contacts; and o nursing personnel in close contact with PLHIV. 18 Presently, there are not much data for PLHIV response to PCV, other than from South Africa and smaller studies in the United States. 452 hIv/aIds tReatment and caRe clInIcal PRotocols foR the who euRoPean RegIon • For unvaccinated HIV-infected adults at increased risk of exposure to poliovirus (such as travel to a polio-endemic country), a primary series of IPV is recommended (25). 2.10. Rabies vaccine Two main types of rabies vaccine are in use: nerve tissue (Semple-type) vaccine and modern cell- derived vaccine. Immunocompromised HIV-infected people might not develop sufficient immunological response, as immunity depends upon the CD4+ T-cell-dependent neutralizing antibody response to the G protein. 2.10.1. Recommendations • Rabies vaccines are used for post-exposure protection and pre-exposure immunogenicity. Ra- bies vaccines are not contraindicated for HIV-infected people and should be administered if indicated (see Annex 3). • If post-exposure treatment must be given to immunocompromised HIV-positive patients, intra- muscular vaccine and rabies immunoglobulin are mandatory, along with serological monitoring of the antibody responses (see section III.3.3 below on rabies immunoglobulin). • People who have demonstrated less than 0.5 IU/ml neutralizing antibody titres after 4–5 doses of rabies vaccine over four weeks should receive additional doses to achieve the required level (23), as rabies antibody titres >0.5 IU/ml are required for protection. 2.11. Tick-borne encephalitis vaccine Tick-borne encephalitis, caused by tick-borne encephalitis virus, infections occur in many parts of Europe (Albania, Austria, Croatia, the Czech Republic, Denmark, Estonia, France (Alsace), Germany, Hungary, Latvia, Lithuania, Norway, Poland, the Russian Federation, Slovakia, southern and central Sweden, Switzerland), corresponding to the distribution of the tick reservoir. The dis- ease has been known by several names, including Russian spring-summer encephalitis (RSSE), Far Eastern encephalitis and central European encephalitis (CEE) (42). Generally risk to the average traveller to affected countries is small. Infections are related to either leisure activities such as hiking, walking and hunting, or working in agriculture and forestry in warm, rural or forested parts of endemic regions. People at risk of infection include foresters, wood- cutters, farmers, military personnel, laboratory workers and tourists who camp, hunt and undertake field-work in rural, forested areas. Pre-exposure prophylaxis is available with the whole virus inactivated vaccines. The standard vac- cination schedule consists of 2 doses given over 4–12 weeks apart, followed by a third dose 9–12 months later. In immunocompetent adults, the rate of seroconversion after 3 doses is 85–100%. For those at risk, boosting is recommended every 3 years. The rapid schedules19 have shown similar ef- ficacy in healthy individuals and are practical for travellers. Whether the rapid vaccination schedule is effective in HIV-infected persons is unknown. Only two published studies have investigated the immunogenicity of vaccination in HIV-infected patients. These studies suggest that the vaccine is less efficacious in HIV-infected individuals than those not infected with HIV, particularly with a CD4 count <500 cells/mm3. Although a four-dose vaccination schedule given at 0, 1, 2 and 9–12 months may improve responses in HIV-infected people, evidence in support of this strategy remains limited (11). 19 For FSME Immun: 2 doses 14 days apart as primary course and followed by a third dose 9-12 months later; for Encepur: 3 doses on days 0, 7 and 21 as primary course and followed by a fourth dose 12-18 months later. 453 ImmunIzatIon of PeoPle lIvIng wIth hIv and PeoPle at RIsk of hIv InfectIon 2.11.1. Recommendations • Immunization should be considered for HIV-infected people who intend to walk, camp or work in heavily forested regions of affected countries during late spring or summer when the ticks are most active, particularly if staying in areas with heavy undergrowth. • The vaccine is also recommended for expatriates whose principal area of residence is in an area where tick-borne encephalitis is endemic. • Either the standard or the rapid vaccination schedule may be considered for HIV-infected people with a CD4 count >400 cells/mm3. • In HIV-infected individuals with a CD4 count <400 cells/mm3, serological testing may be con- sidered one month after the second dose. • In case of an inadequate antibody response, two further vaccine doses should be given, one im- mediately and one at 9–12 months after the first dose. • In the absence of serological testing, a 4-dose vaccination schedule (0, 1, 2 and 9–12 months) should be adopted to improve response rates (11). • The booster recommendation is the same for HIV-infected individuals as for immunocompetent people. • Due to the possibility of reduced responses to vaccination in immunocompormised HIV-in- fected individuals, the importance of protective clothing and insect repellent use should be emphasized. 2.12. Typhoid vaccine (Vi polysaccharide) HIV-infected people are at increased risk of infection with Salmonella species. In addition, im- munodeficiency predisposes patients to bacteraemia, antibiotic resistance, relapsing disease and persistent infection (11). A parenteral killed vaccine composed of purified Vi polysaccharide (from S. typhi) has been shown to be moderately (50–80%) effective (43), with one dose administered subcutaneously or intramus- cularly. The vaccine confers protection 7 days after injection for at least 2 years. For persons at risk, boosting is recommended every 3 years. 2.12.1. Recommendations • Owing to low efficacy and high rates of associated adverse events, use of old, heat inactivated whole cell typhoid vaccine is not recommended, although this vaccine is still produced in some countries mainly for economic reasons (43). • Although not required for international travel, vaccination with the Vi polysaccharide vaccine is recommended for all HIV-infected people who are due to travel to areas in which there is a recognized risk of exposure and who will be intimate with a documented carrier. • One dose of the vaccine should be given at least 2 weeks before the expected exposure. • A booster is recommended every 3 years in those who remain at risk, this interval might be considered to be reduced to 2 years, if the CD4 count is <200 cells/mm3, as typhoid vaccines are not 100% protective and responses may be further reduced in PLHIV. • Travellers should be advised to follow strict food and drink precautions. 2.13. Other killed antigens Other vaccines containing killed antigens, including Japanese encephalitis, plague and anthrax, do not pose a risk to PLHIV, regardless of their immunological status. 2.13.1. Recommendation • These vaccines should be used in the same manner as for non HIV-infected people. 454 hIv/aIds tReatment and caRe clInIcal PRotocols foR the who euRoPean RegIon 3. Use of immunoglobulins 3.1. Hepatitis B immunoglobulin (HBIg) Temporary immunity may be obtained using HBIg for post-exposure prophylaxis. HBIg is used for passive immunization of: • newborn infants of HBsAg-positive mothers; • people having percutaneous, mucous membrane or sexual exposure to HBsAg-positive blood or body fluids; and • liver transplant patients. 3.1.1. Recommendations • Immunocompromised people, including PLHIV, should receive HBIg for the same indications and in the same doses as immunocompetent people. • As a rule, HBIg should be used as an adjunct to hepatitis B vaccine. All candidates for HBIg are by definition in a high-risk category and should therefore be considered for a concurrent hepatitis B vaccine series. • The people for whom HBIg is indicated include: o premature infants who are born to HBsAg-positive women and women with unknown HB- sAg status, and who should receive immunoprophylaxis with hepatitis B vaccine and may receive HBIg20 at or shortly after birth; o infants born to HBsAg-positive mothers, preferably within 12 hours of birth but at a differ- ent site from the hepatitis B vaccination; o HBsAg-negative people who do not respond to HBV vaccine, and who should be counselled on preventing HBV infection and the need for HBIg prophylaxis against any possible paren- teral exposure to HBsAg-positive blood; o susceptible sexual contacts of people with acute HBV infection, within 14 days of the last sexual contact;21 o unvaccinated infants whose mothers or primary caregivers have acute HBV infection, in which case the first dose of the hepatitis B vaccine series should also be given;22 and o people who are household contacts of people with acute HBV infection and who have been exposed to the blood of the infected person (for example, by sharing a toothbrush or razor), in which case they should also be given the first dose of the hepatitis B vaccine series.23 3.2. Human normal immunoglobulin (HNIg) 3.2.1. Hepatitis A 3.2.1.1. Recommendations • For the prevention of hepatitis A,24 HNIg should be administered in the same way to both immu- nocompromised and immunocompetent people and for the same indications (25). Concurrent administration of HNIg and hepatitis A vaccine does not appear to significantly influence the formation of protective antibodies (23). • HNIg is indicated to prevent hepatitis A in the following groups of people: o people travelling to high-risk areas less than four weeks after an initial dose of hepatitis A vaccine should receive HNIg at a different site from the hepatitis A vaccination; 20 The protection against perinatally acquired infection achieved by immediate (within 24 hours) hepatitis B vaccination is not significantly improved by the addition of HBIg (44). 21 If the last sexual contact was more than 14 days prior, hepatitis B vaccination should be initiated, although the amount of protection afforded by post-exposure prophylaxis given this late is not known. HBIg is not recommended in this situation. 22 HBIg is not needed for infants who have received or are scheduled to receive a second dose of vaccine. 23 Routine hepatitis B vaccination should also be considered for nonsexual household contacts without blood exposure, espe- cially children and adolescents. 24 To prevent HAV infection, administration of HNIg is recommended before or within two weeks of HAV exposure. Later administration of HNIg often only attenuates the clinical expression of HAV infection. 455 ImmunIzatIon of PeoPle lIvIng wIth hIv and PeoPle at RIsk of hIv InfectIon o children younger than 1 travelling to high-risk areas should receive 0.02–0.06 ml/kg, de- pending on length of stay, since hepatitis A vaccine is not approved for children younger than 1; o people exposed to HAV who have not previously received hepatitis A vaccine, who should be given HNIg as soon as possible within two weeks of exposure; o people in close contact with a person who has hepatitis A; o staff and children at child care centres where a hepatitis A case has been diagnosed; and o people in certain common-source exposure situations (for example, patrons of a food estab- lishment with an HAV-infected food handler where the risk of transmission is determined to be high). • People who received a dose of hepatitis A vaccine at least one month before an exposure do not need HNIg. 3.2.2. Measles 3.2.2.1. Recommendations • For immunocompromised people (including those with HIV infection), HNIg is indicated to prevent measles following exposure. • If immediate protection against measles is required for immunocompromised patients with con- traindications for measles vaccination, including infants younger than 1, passive immunization with HNIg 0.5 ml/kg of body weight (maximum dose 15 ml) should be administered intramus- cularly as soon as possible after exposure. • Exposed symptomatic HIV-infected patients should receive HNIg regardless of their previous vaccination status, as measles vaccine may not be effective in such patients and the disease may be severe. • For immunocompromised people receiving HNIg for measles prophylaxis, measles vaccination should be delayed for six months following HNIg administration. 3.3. Human rabies immunoglobulin (HRIg) 3.3.1. Recommendations • Immunocompromised patients, including those with HIV infection, should receive HRIg for the same indications and in the same doses as immunocompetent patients do. • HRIg is indicated for Category III contact (single or multiple transdermal bites or scratches, contamination of mucous membrane with saliva from licks), along with the first dose of the rabies vaccine series. • HRIg treatment is not necessary for people vaccinated against rabies who have demonstrated neutralizing antibody titres of at least 0.5 IU/ml (two intramuscular doses of a cell-derived vac- cine separated by three days are sufficient for such cases). • If post-exposure treatment must be given to an immunocompromised HIV-infected person, HRIg is mandatory, along with the first dose of an intramuscular rabies vaccine series. • In addition, the antibody responses should be monitored serologically.

Recommendations • TIg is recommended for people with tetanus and to prevent tetanus in inadequately immunized people with wounds or other conditions associated with tetanus, regardless of their HIV and im- mune status. TIg neutralizes circulating unbound tetanus toxin. It does not affect toxin that has reached the nervous system. • Dosage is the same for PLHIV as for others. • For the treatment of tetanus, a single intramuscular dose of 3000–5000 units is generally recom- mended for children and adults. • Indications for TIg are: o wounds that are neither clean nor minor in people who have had no more than two prior doses of Td toxoid (vaccine) or who have an uncertain history of TIg immunization, Td toxoids should also be administered;25 o any injury other than a clean minor wound, in combination with a contraindication for teta- nus toxoid; or o symptoms consistent with tetanus disease. • Intravenous immunoglobulin (IgIV) contains tetanus antitoxin and may be used if TIg is not available. 3.5. Varicella-zoster immunoglobulin (VZIg) The most important use of VZIg is for passive immunization of neonates and susceptible severely immunocompromised people, including PLHIV, after significant exposure to chickenpox or zoster. Immunocompromised patients who are exposed to varicella and receive VZIg may have lower rates of complications and infections. The risks of VZIg appear to be negligible, though the cost can be substantial. 3.5.1. Recommendations • For prophylaxis of chickenpox, susceptible HIV-infected children (those who have no history of chickenpox or shingles or who have no detectable VZV antibodies) should be administered VZIg as soon as possible within 96 hours after close contact with chickenpox or shingles. • VZIg is also recommended for VZV-susceptible HIV-infected pregnant women within 96 hours after exposure to VZV. If oral aciclovir is used, VZV serology should be performed so that the drug can be discontinued if the patient is seropositive for VZV (25). 25 Early doses of toxoid do not induce immunity, but only prime the immune system. The TIg provides temporary immunity by directly providing antitoxin, ensuring that a protective level of antitoxin is achieved even if an immune response has not yet occurred. 457 ImmunIzatIon of PeoPle lIvIng wIth hIv and PeoPle at RIsk of hIv InfectIon Annex 1.

Rabies vaccines Pre-exposure rabies vaccination may be performed with any of the modern cell-derived vaccines and is rec- ommended for anyone at risk for exposure to rabies virus. Traditionally, this recommendation includes: • laboratory staff • veterinarians • animal handlers • wildlife officers with frequent exposure to potentially infected animals • visitors to highly rabies-enzootic areas26 who may be exposed to rabies hosts.27 The pre-exposure schedule of modern cell-derived rabies vaccines requires intramuscular doses of 1 ml or 0.5 ml, depending on the vaccine, given on Days 0, 7 and 28.28 The indication for post-exposure vaccina- tion with these vaccines (with or without rabies immunoglobulin) depends on the type of contact with the rabid animal.29 Depending on vaccine type, the post-exposure schedule prescribes intramuscular doses of 1 ml or 0.5 ml given as 4–5 doses over four weeks. For rabies-exposed patients who have previously under- gone complete pre-exposure vaccination or post-exposure treatment with cell-derived rabies vaccines, two intramuscular doses of a cell-derived vaccine separated by three days are sufficient. Rabies immunoglobulin treatment is not necessary in such cases. The same rules apply to people vaccinated against rabies who have demonstrated neutralizing antibody titres of at least 0.5 IU/ml. The human diploid cell rabies vaccine is regarded as the gold standard for cell-derived rabies vaccines.30 The WHO requirement is a potency of at least 2.5 IU per intramuscular dose for all cell-derived vaccines. Despite the use of potent, modern cell-derived vaccines, about one failure in one million post-exposure treatments does occur. Careful analyses show that such failures are almost always associated with severe lesions on or near the head and/or inappropriate administration of the treatment. A complete post-exposure treatment using nerve tissue vaccines involves a prolonged and painful immuniza- tion course of up to 23 injections. Furthermore, protective potency nerve tissue vaccines are inferior to mod- ern cell-derived vaccines. Obviously, these vaccines are not recommended for pre-exposure immunization. 26 More than 2.5 billion people live in regions where rabies is endemic, in Africa, Asia and South America. It is estimated that each year at least 50 000 people die from rabies, and that more than 10 million receive post-exposure vaccination. Children aged 5–15 years are at particular risk (23). 27 According to age-stratified studies of incidence, those at greatest risk are probably children living in rabies-enzootic regions of the developing world (23). 28 Major vaccine manufacturers recommend one booster dose after one year, and to ensure protection in people at continued risk, booster vaccinations every five years, or ideally, at intervals dictated by regular testing for rabies antibodies (titres >0.5 IU/ml required for protection). 29 The types of contact are Category I: touching or feeding animals, or licks on the skin; Category II: nibbling of uncovered skin, minor scratches or abrasions without bleeding, or licks on broken skin; and Category III: single or multiple transdermal bites or scratches, or contamination of a mucous membrane with saliva from licks. For Category I, no treatment is required; for Category II, immediate vaccination is recommended; and for Category III, immediate vaccination and administration of rabies immunoglobulin are recommended, in addition to immediate washing and flushing of all bite wounds and scratches. 30 Other cell-derived rabies vaccines are vero cell and purified chick embryo cell vaccines. No clinically important differences were observed when these vaccines were evaluated together with human diploid cell vaccines in studies on both post-exposure protection and pre-exposure immunogenicity (23). 460 hIv/aIds tReatment and caRe clInIcal PRotocols foR the who euRoPean RegIon Annex 4. Glossary Active immunity is usually permanent protection produced by a person’s own immune system. One way to acquire active immunity is to have the natural disease. In general, once patients recover from infectious diseases, they will be immune to those diseases for the rest of their lives. Antibodies are proteins that are produced by the immune system in response to specific antigens, thereby helping the body fight infection and foreign substances. Antigens are substances, foreign to the body, that stimulate the production of antibodies by the immune sys- tem. Antigens can either be live (such as viruses and bacteria) or inactivated. An antitoxin is a solution of antibodies (for example, diphtheria antitoxin and botulinum antitoxin) derived from the serum of animals immunized with specific antigens. Antitoxins are used for conferring passive im- munity and for treatment and are usually permanent. An asymptomatic HIV-infected person is one with a confirmed HIV diagnosis but with no clinical signs or symptoms of the infection, corresponding to WHO Clinical Stage 1. (For staging, see Protocol 1, Patient evaluation and antiretrovital treatment for adults and adolescents, Annex 2, and Protocol 11, Paediatric HIV/AIDS treatment and care, Annex 1). A contraindication is a condition in a recipient that greatly increases the likelihood of a serious adverse reaction that could seriously harm the recipient. In general, vaccines should not be administered when a contraindicated condition is present. An immune response is the defence that the immune system develops against antigens. It usually involves the production of protein molecules, antibodies (or immunoglobulins), and of specific cells (also known as cell-mediated immunity) whose purpose is to facilitate the elimination of foreign substances. The immune system is a complex system of interacting cells whose primary purpose is to identify foreign substances referred to as antigens, and to defend it against infection, disease and other foreign substances. The body’s immune system naturally produces antibodies in this defence process. Immunity is the ability of the human body to tolerate the presence of material indigenous to the body and to eliminate foreign material. This discriminatory ability provides protection from infectious disease, since the immune system identifies most microbes as foreign. Immunity to a microbe is usually indicated by the presence of an antibody to that organism. Immunity is generally very specific to a single organism or group of closely related organisms. There are two basic mechanisms for acquiring immunity, active and passive. Immunoglobulin (Ig) is a sterile solution containing antibodies from human blood, also known as human normal immunoglobulin (HNIg), immune serum globulin (ISG) or gamma globulin (IgG). Ig is used to prevent the spread of some diseases among people who are in close contact with each other. Intended for intramuscular administration, it is primarily indicated for routine maintenance of immunity among certain immunodeficient people and for passive immunization against measles and hepatitis A. Ig does not transmit hepatitis B virus, HIV or other infectious diseases. Immunization is an inclusive term denoting the process of inducing or providing immunity artificially by administering an immunobiological product. Immunization can be active or passive. Active immunization is the production of antibody or other immune responses through the administration of a vaccine or toxoid. Passive immunization is the provision of temporary immunity by the administration of preformed antibod- ies, such as immunoglobulins and antitoxins. 461 ImmunIzatIon of PeoPle lIvIng wIth hIv and PeoPle at RIsk of hIv InfectIon Immunologic memory is persistent protection for many years after an infection. Following exposure of the immune system to an antigen, certain cells (memory B-cells) continue to circulate in the blood (and also in the bone marrow) for many years. Upon exposure to the antigen, these memory cells begin to replicate and produce very rapidly to re-establish protection. Immunosuppression is the suppressed immune status of an individual caused by diseases (such as HIV/ AIDS, congenital immunodeficiency, leukaemia, lymphoma or generalized malignancy) or drugs (such as alkylating agents, antimetabolites or radiation therapy). The level of immunosuppression can be measured by CD4 count or by CD4 percentage of total lymphocytes. Inactivated vaccines can be composed of whole viruses or bacteria, or fractions of either. Fractional vac- cines are either protein-based or polysaccharide-based. Protein-based vaccines include toxoids (inactivated bacterial toxins) and subunit or subvirion products. Most polysaccharide-based vaccines are composed of pure cell-wall polysaccharide from bacteria. Conjugate polysaccharide vaccines are those in which the poly- saccharide is chemically linked to a protein. This linkage makes the polysaccharide a more potent vaccine. Vaccine antigens may also be produced by genetic engineering technology. These products are sometimes referred to as recombinant vaccines. Intravenous immunoglobulin (IgIV) is a product derived from blood plasma from a donor pool similar to the Ig pool, but prepared so it is suitable for intravenous use. IgIV does not transmit infectious diseases. It is primarily used for replacement treatment in primary antibody-deficiency disordersand for the treatment of Kawasaki disease, immune thrombocytopenic purpura, hypogammaglobulinaemia in chronic lymphocytic leukaemia, and some cases of HIV infection. Live attenuated vaccines are produced by modifying a disease-producing (“wild”) virus or bacteria in a laboratory. The resulting vaccine organism retains the ability to replicate and produce immunity, but it usu- ally does not cause illness. Passive immunity is protection by products produced by an animal or another human and transferred to the recipient, usually by injection. Passive immunity often provides effective protection, but this protection wanes over time, usually a few weeks or months. Specific immunoglobulins are special preparations obtained from blood plasma from donor pools prese- lected for high antibody content against a specific antigen (for example, hepatitis B immunoglobulin, vari- cella-zoster immunoglobulin, rabies immunoglobulin or tetanus immunoglobulin). Like Ig and IgIV, these preparations do not transmit infectious diseases. A symptomatic HIV-infected person is a person presenting with signs and symptoms of HIV infection. Mild, advanced and severe HIV disease corresponds to WHO Clinical Stages 2, 3 and 4, respectively (see Annex 2 and the annexes mentioned under “asymptomatic HIV-infected person” above). A toxoid is a modified bacterial toxin that has been made non-toxic but retains the ability to stimulate the formation of antitoxin. Vaccination is the physical act of administering any immunobiological agent (vaccine, toxoid or immuno- globulin) to a person to produce active immunity. Vaccine is a suspension of live (usually attenuated) or inactivated microorganisms (e.g. bacteria, viruses or rickettsiae) or fractions thereof, administered to induce immunity and prevent infectious diseases or their consequences. Some vaccines contain highly defined antigens (such as the polysaccharide of Haemophilus influenza type b or the surface antigen of hepatitis B); others contain antigens that are complex or incom- pletely defined (for example, killed Bordetella pertussis or live attenuated viruses). Vaccines interact with the 462 hIv/aIds tReatment and caRe clInIcal PRotocols foR the who euRoPean RegIon immune system and often produce an immune response similar to that produced by the natural infection, but do not subject the recipient to the disease and its potential complications.

Policy issues Following exposure to HIV, there are currently only two known means to reduce the risk of devel- oping HIV infection: post-exposure prophylaxis (PEP) and interventions to prevent mother-to-child transmission (see Protocol 10, Prevention of HIV transmission from HIV-infected mothers to their infants). • PEP policy should be part of a comprehensive national HIV/AIDS policy and also included any occupational health and post sexual assault services policies. • PEP services should be integrated into existing health services and provided as part of a compre- hensive standard precautions package that reduces workplace exposure to infectious hazards. • Eligibility for and access to PEP should be equitable, without discrimination on grounds of age, gender, sexual orientation, citizenship, occupation or incarceration. • Decisions about whether to provide PEP should be based on clinical consideration of risk factors. • PEP services should be provided after: ° occupational exposure to HIV infection or potential HIV infection; ° accidental non-occupational exposure to HIV infection or potential HIV infection, including nosocomial exposure. • The human rights and confidentiality of people accessing PEP should be respected. • In the context of exposure and/or the provision of PEP, informed consent needs to be obtained for HIV testing and counselling in accordance with both client and provider initiated counselling and testing guidelines. (See Annexes 1 and 2 for examples of informed consent forms.) • In special situations where the individual has limited or no capacity to consent to an HIV test (such as a child or an unconscious or mentally ill adult), a legal guardian, custodian or other per- son designated in advance by the patient may be able to provide consent, depending on national or regional legislation. 470 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION II. Background and general considerations PEP is a medical response given to prevent the transmission of pathogens after potential exposure. PEP for HIV refers to a set of comprehensive services to prevent HIV infection in exposed indi- viduals. These services include, first aid care, counselling and risk assessment, HIV testing based on informed consent, and depending on risk assessment, the provision of short term (28 days) antiretroviral (ARV) drugs, with follow up and support. 1. Occupational exposure to HIV 1.1. Definition According to the ILO/WHO guidelines for occupational PEP, “an occupational exposure is defined as a percutaneous, mucous membrane or non-intact skin exposure to blood or body fluids that oc- curs during the course of an individual’s employment. This applies to health care workers (HCW) and to non-health workers.” (1) An occupational exposure may place a worker1 at risk of HIV infec- tion through injuries such as those involving a potentially contaminated needle or sharp instrument or chapped, abraded skin or contact with mucous membranes. 1.2. Risk for transmission The risks for occupational transmission of HIV vary with the type and severity of exposure (2, 3). • The average risk for HIV transmission after a percutaneous exposure to HIV-infected blood has been estimated to be approximately 0.23% (95% confidence interval (CI) = 0.00–0.46%) (3). • The average risk after a mucous membrane exposure is estimated to be approximately 0.09% (CI = 0.006–0.5%) (4). • Factors associated with an increased likelihood of transmission include: ° deep (intramuscular) injury ° injury caused by a device that enters a blood vessel ° injury with a hollow-bore needle ° a source patient with a high viral load (VL). • Episodes of HIV transmission have also been documented after non-intact skin exposure. Al- though the average risk for transmission by this route has not been precisely quantified, it is estimated to be much less than the risk for mucous membrane exposures. • The risk for transmission after exposure to HIV-infected fluids or tissues other than blood has not been quantified either, but it is considered probably lower than for blood exposure. 1.3. Potentially infectious body fluids (5) • Blood and visibly bloody body fluids are considered as potentially infectious. • The risks of HIV transmission from cerebrospinal, synovial, pleural, peritoneal, pericardial and amniotic fluids are unknown. • Semen and vaginal secretions have not been implicated in occupational transmission from pa- tients to health care providers. • Faeces, nasal secretions, saliva, sputum, sweat, tears, urine and vomitus are not considered po- tentially infectious unless they contain visible blood. 1 Besides health care providers (physicians, dental personnel, nurses, laboratory and autopsy personnel, nursing assistants, medical technicians, pharmacists, medical students et al.), others at risk of workplace exposure include police, fire and ambu- lance personnel. 471 post-exposure prophylaxis for hiv infection 1.4. Factors affecting the risk for HIV transmission after an occupational exposure Epidemiological and laboratory studies suggest that multiple factors might affect the risk for HIV transmission after an occupational exposure (2, 3). • For percutaneous exposure to HIV, increased risk for HIV infection is associated with exposure to blood from the source person, as indicated by: ° a device (e.g. a needle) visibly contaminated with blood; or ° a procedure that involved a needle being placed directly in a vein or artery or in a deep injury. • High viral load in the source person is also a condition that may increase the risk of HIV trans- mission. 2. Non-occupational exposure Due to ethical considerations, it is not possible to make prospective randomized controlled stud- ies to evaluate the efficacy of PEP in preventing HIV after non occupational exposure. Neither are there data from studies or case reports providing definitive evidence of the efficacy of PEP after sexual, injecting drug or other non-occupational exposures to HIV. However, several related data sets from occupational exposure, mother-to-child transmission and animal studies support the bio- logical plausibility of its effectiveness (6–10). 2.1. Definition Non-occupational exposure is any direct mucosal, percutaneous2 or intravenous contact with poten- tially infectious body fluids that occurs outside perinatal or occupational situations (11): [N]on-occupational exposure [is considered to be] all accidental and sporadic incidents in which contact with blood or other body fluids (semen, vaginal secretions, etc.) that pose a potential risk for HIV infection occurred … Non-occupational exposure includes unprotected sexual expo- sure, sexual exposure involving a broken or slipped condom, injecting drug users (IDUs) sharing equipment, accidental needlestick injuries, bite wounds, mucosal exposure, etc. Non-occupational exposure also includes nosocomial exposure. Accidental exposure to HIV origi- nating in a health care facility includes cases where a patient is exposed by a health care worker (HCW) or another patient (12). Three scenarios can result in a patient being exposed to HIV noso- comially (13): • an HIV-infected HCW who does not know his/her HIV status performing an exposure-prone procedure;3 • an HIV-infected HCW performing a non-exposure-prone procedure (and when there is e.g. a spontaneous nosebleed or a physical assault on the HCW); or • the event that an invasive device or product contaminated with HIV by use on one patient is ac- cidentally reused on another patient. 2 Percutaneous non-occupational exposure includes but is not limited to accidental or criminal sticks with needles contaminated with blood or other bodily fluids. 3 Exposure-prone procedures are those in which there is a risk that injury to the HCW could result in exposure of the patient to the blood of the HCW, including some common procedures found in surgery, obstetrics, gynaecology, midwifery and dentistry (13). HCWs who know that they are HIV infected, should not be involved in such procedures. 472 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 2.2. Risk for transmission The estimated per-act transmission risk from unprotected exposure to a person known to be HIV- infected is low. It varies depending on the type of exposure.

Evaluation of exposure An exposure incident should be evaluated for the potential of HIV transmission based on the type of body substance involved, the transmission route and the severity of the exposure. The following factors should be considered in evaluating the risk of transmission: • the type of exposure: ° percutaneous injury ° mucous membrane exposure ° open wound exposure; • the type and quantity of fluid/tissue: ° blood; ° a fluid that contains blood; ° a potentially infectious fluid (e.g. seminal, vaginal, cerebrospinal, synovial, pleural, perito- neal, pericardial or amniotic fluid) or tissue; ° concentrated virus (direct contact); and • the recency of exposure. 2. Evaluation of the exposure source When feasible, the person whose blood or body fluid is the source of potential exposure should be evaluated for HIV. • If an exposure source is known and available, testing the source person for HIV is recommended as soon as possible, or testing the suspected exposure material (blood, tissue, etc) if the person is unavailable. • Procedures that should be strictly followed for testing the source person include: ° obtaining informed consent (see suggested form in Annex 1) ° pre- and post-test counselling ° referral if positive for appropriate post-test counselling, care and treatment. • A rapid HIV-antibody test is preferred in situations where enzyme-linked immunosorbent assay (ELISA) tests cannot be completed within 24–48 hours. • Two positive ELISA or rapid HIV-antibody tests are considered to be highly suggestive of infec- tion, whereas a negative result is an excellent indicator of the absence of HIV antibody. • In no way should administration of PEP for the exposed person, be delayed while waiting for test results. • The routine use of direct virus assays (e.g. an HIV p24 antigen enzyme immunoassay (EIA) or HIV RNA tests) to detect infection among exposure sources is usually not recommended (25) because: ° the infrequency of occupational seroconversion and the increased costs of these tests do not warrant routine use in this context; and ° the relatively high rate of false-positive results for these tests in this context can lead to un- necessary anxiety or treatment (14, 26). • The exposure source should also be tested for hepatitis C and B viruses (HCV and HBV). • Information to consider when evaluating an exposure source includes: ° previous HIV test results; and ° clinical symptoms (e.g. acute syndrome suggestive of primary HIV infection and history of possible HIV exposure within the last three months) or personal history suggesting possible exposure to HIV; and ° history of tratment, duration, its success or failure, type of regime and adherence. 474 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION • If the exposure source is unknown, cannot be tested or refuses to be tested, the risk of HIV trans- mission should be assessed epidemiologically, if possible. Relevant information includes: ° type of exposure ° prevalence of HIV in the population where the source material originates. • If the source person is known to have HIV infection, the following information is also useful to know in determining an appropriate PEP regimen: ° clinical stage of the HIV infection; ° CD4 cell count; ° viral load, as a high plasma viral load increases the risk of transmission in all cases (27); ° antiretroviral treatment history; ° genotypic or phenotypic viral resistance results (if available); ° in a case of sexual exposure, the existence of genito-oral ulcers or other sexually transmitted infections (STIs), and whether menstruation or other bleeding occurred at the time (24); and ° in the case of an accidental needle-stick exposure, whether fresh blood was present and whether it was a deep injury or intravenous injection (all increase the risk of HIV transmis- sion) (6). • If this information is not immediately available, initiation of PEP, if indicated, should not be delayed. Appropriate changes in the PEP regimen can be made if new information emerges after PEP has been started. • If the source person’s results are HIV seronegative at post-exposure evaluation and presents no clinical evidence of AIDS or HIV infection, no further testing of the source is indicated. The likelihood of the source person being in the “window period” of HIV infection with no symp- toms of acute retroviral syndrome is extremely small. 3. Evaluation of the exposed person Evaluation of exposed persons (regardless if it is occupational or non-occupational) has to be done as soon as possible and within hours after an exposure. The following evaluations are recommended: • an HIV serological baseline test to establish infection status at the time of exposure, with pre- and post-test counselling and based on informed consent (see Annex 2); • direct virus assays for any exposed person who has an illness compatible with an acute retroviral syndrome, regardless of the time elapsed since exposure; • evaluation of circumstances, medical conditions and medications that might influence drug se- lection for PEP (e.g. pregnancy or breastfeeding); It is useful to perform the following baseline tests if resources are available: • baseline laboratory testing to monitor for adverse reactions: ° complete blood count (CBC) with differential and platelets ° liver function tests (LFTs) (asparate aminotransferase (AST), alanine aminotransferase (ALT), bilirubin) ° urea or serum creatinine; and • baseline serological tests for hepatitis C and B (HCV antibodies and hepatitis B surface antigen (HBsAg)). 3.1. Additional considerations for non-occupationally exposed people In addition, those seeking care after potential non-occupational exposure to HIV should also be evaluated for the following information: • frequency of exposures to HIV; • history of specific sexual, drug-injecting or other behaviours that might have heightened the risk for acquiring HIV infection; • if an accidental needle-stick exposure, whether there was fresh blood and whether it was a deep injury or intravenous injection (6); and • if a sexual exposure: 475 post-exposure prophylaxis for hiv infection ° condom use ° presence of STIs (as determined by testing) ° need for emergency contraception or pregnancy testing (for females) ° presence of sexual assault, by one or more persons ° whether menstruation or other bleeding was present at time of exposure. 476 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION IV. Clinical management of people incidentally exposed to HIV 1. First aid For a potential exposure to HIV, “first aid” refers to the actions that should be taken immediately afterwards. The aim of first aid is to reduce contact time with the source person’s body fluids (in- cluding blood) and tissues, and to clean and decontaminate the exposure site to reduce the risk of infection (28). If the skin is broken following an injury with a used needle or other sharp instrument, take the fol- lowing steps. • Wash the injury immediately, using soap. • Encourage the puncture wound to bleed freely under running water for several minutes or until bleeding ceases. • If running water is not available, clean site with a gel or hand cleaning solution. • Do not use any strong solutions, such as alcohol, bleach or iodine, as they may irritate the wound and make the injury worse. • Do not squeeze or rub the injury site. • Do not suck a puncture wound. After a splash of blood or body fluids, do the following: • for a splash on unbroken skin: ° wash the area immediately; ° if running water is not available, clean the area with a gel or hand rub solution; ° do not use any strong solutions, such as alcohol, bleach or iodine, as they may irritate the af- fected area; ° use mild disinfectants, such as Chlorhexidine gluconate 2–4%; ° do not rub or scrub area; ° do not use a dressing. • for a splash in the eye: ° irrigate the exposed eye immediately with water or normal saline. Sit in a chair, tilt the head back and have a colleague gently pour water or normal saline over the eye, gently pulling the eyelids up and down to make sure the eye is cleaned thoroughly; ° if wearing contact lenses, leave them in place while irrigating, as they form a barrier over the eye and will help protect it; once the eye has been cleaned, remove the contact lenses and clean them in the normal manner, which will make them safe to wear again; ° do not use soap or disinfectant on the eye. • for a splash in the mouth: ° spit the fluid out immediately; ° rinse the mouth thoroughly, using water or saline, and spit out again. Repeat this process sev- eral times. • do not use soap or disinfectant in the mouth. 2. Counselling an exposed person After the evaluation, health care workers should provide counselling on risk-reduction behaviour to the exposed person regardless of how the individual was exposed, and of whether or not antiretro- viral (ARV) drugs will be recommended for PEP, as such, counselling can reduce the risk of future exposures (29, 30). 477 post-exposure prophylaxis for hiv infection It should be made clear during the counselling session that PEP is not mandatory. An informed consent form (see Annex 2) should be signed if the exposed person opts for PEP. In addition to the information outlined on the informed consent form, the exposed people should be counselled on: • avoiding pregnancy and seeking safe alternatives to breastfeeding; • avoiding blood, tissue or sperm donation; • using condoms for sexual intercourse up to the sixth month test confirming that the exposed person remains seronegative; • standard precaution measures for those at risk of workplace exposure; and • the need for clinical and serological follow-up. As stated on the consent form, there is a strong need for adherence to PEP regimens, for further information on adherence refer to Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents, for information on adherence issues. Psychological support should be an integral part of counselling and include appropriate referrals as needed. Counselling on risk-reduction behaviour after non-occupational exposure should also focus, where indicated, on: • safer injecting practices, with referral to harm-reduction programmes and drug-dependence treatment services; • STI treatment, with referral to appropriate services; and • contraception and condom use. Furthermore, counselling on sexual abuse should be provided, where needed, with appropriate referrals, such as legal services. 3. No indication for ARV use for PEP purposes Some situations do not require initiation of ARVs for prophylaxis purposes. They include (26): • if the exposed person has previously tested positive for HIV (this needs to be documented); • if exposure is chronic (occurring regularly versus occurring occasionally4), e.g. between serodis- cordant sex partners who rarely use condoms or IDUs who share injecting equipment; • if the exposure does not pose a risk of transmission, e.g.: ° exposure of intact skin to potentially infectious body fluids; ° sexual intercourse with proper condom use during which the condom remained intact; ° exposure to non-infectious body fluids (such as faeces, saliva, urine, sweat) with no blood contamination; ° exposure to body fluids from a person known to be HIV-seronegative, unless identified as at high risk for recent infection within the “window period”; and • if the exposure was more than 72 hours previous (however, consider referring for counselling, testing and clinical follow-up). Note that the final decision for prescribing or not prescribing PEP should be made on the basis of risk evaluation, the patient–physician relationship, bearing in mind that PEP should never be con- sidered a primary prevention strategy (11). 4 People who are occasionally or episodically exposed to HIV, such as sexually assaulted sex workers who otherwise use condoms, episodically abused children, medical waste workers with repeated sharps injuries, et al should be considered for PEP based on previously described evaluation (see section III of this document). 478 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 4. Time of initiation and duration of PEP PEP should be initiated within hours of exposure – ideally within 2 hours and not later than 72 hours after exposure and should not be delayed while waiting for tests results. The optimal duration of PEP is unknown. Data show that four weeks of ZDV has appeared protec- tive in occupational and animal studies. PEP should be administered for four weeks if tolerated (9, 31–33). 5. Considerations in choosing an ARV regimen for PEP The only PEP efficacy data are from a retrospective case control study (6) on a zidovudine mono- therapy, taken as prophylaxis measure. The model in the study indicates reducing risk of HIV acqui- sition by approximately 81% in health care workers after percutaneous exposure. No evidence indicates that a three-ARV combination is more effective than a two-ARV combina- tion, or two-ARV combination is more effective than three-ARV combination. Some data suggest that there is significant toxicity associated with three-ARV regimens, while two-ARV combinations are generally well tolerated (29, 34). Offering a two-drug regimen is a viable option, primarily be- cause the benefit of completing a full course of this regimen exceeds the potential benefit of adding a third agent and risking non-completion (35). For the vast majority of exposure cases, whether occupational or non-occupational, and whether due to percutaneous injuries or to contact with mucous membrane or non-intact skin, the regimen with two ARVs considered to be sufficient. However, suspected or proven drug resistance in a source person might guide a decision to prescribe a three ARV drug regimen. If a question exists concerning whether to use a two-drug or three-drug regimen, start the two-drug regimen immediately rather than delay administering PEP. 6. Antiretroviral regimens and drugs for PEP 6.1. Two ARV drug regimens The two-drug ARV regimen (see Table 2) consists of two nucleoside or nucleotide reverse tran- scriptase inhibitors (NRTIs). Table 2. two-drug arv regimens Preferred ZDV + 3TCa (or FTC) Alternatives TDF + FTCb (or 3TC) or d4T + 3TC a The combination ZDV + 3TC is available as a fixed-dose combination (FDC) (Combivir), one tablet twice daily (BID). b The combination TDF + FTC is available as an FDC (Truvada), one tablet once daily (OD). 6.2. Three ARV drug regimens Expanded ARV regimens (see Table 3) are combinations of three ARVs (two NRTIs + one protease inhibitor (PI)). They are recommended for exposures that pose an increased risk of transmission or that involve a source in whom antiretroviral drug resistance is likely (see section 5). 479 post-exposure prophylaxis for hiv infection Table 3. thre- drug arv regimens Preferred ZDV + 3TCa + LPV/r Alternatives ZDV + 3TCa + SQV/r or ATV/r or FPV/r or TDF + FTCb + SQV/r or ATV/r or FPV/r or d4t + 3TC +SQV/r or ATV/r or FPV/r a The combination of ZDV + 3TC is available as an FDC (Combivir), one tablet BID. b The combination of TDF + FTC is available as an FDC (Truvada), one tablet OD. 6.3. ARV dosages • ZDV: 300 mg per os (PO), BID with food • 3TC: 150 mg PO, BID or 300 mg PO, OD • FTC: 200 mg, PO, OD • TDF: 300 mg, PO, OD • d4T: 30 mg PO, BID • LPV/r: 400 mg/100 mg PO, BID with food • SQV/r: 1000 mg/100 mg PO, BID • ATV/r: 300 mg/100 mg PO, OD • FPV/r: 700 mg/100 mg PO, BID In cases involving children who need PEP, dosages should be adjusted accordingly (please refer to Protocol 11, Paediatric HIV/AIDS treatment and care). For further details regarding essential information about ARVs please refer to Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents, Annex 4. 6.4. ARVs not recommended for PEP Some ARVs are not recommended for use in PEP, primarily because of a higher risk for potentially serious life-threatening events: abacavir (ABC), the combination of didanosine (ddI) and d4T, and NVP (36, 37). Amprenavir (APV) should not be given to pregnant or lactating women (38–40). In addition, EFV is not recommended because of low genetic barrier. An exceptional use of efavirenz (EFV) may be considered when: • the exposed person cannot tolerate available boosted PIs; • the source is known to be infected with drug-resistant HIV that is sensitive to EFV. 7. Follow-up of exposed persons People who have been potentially exposed to HIV, whether occupationally or non-occupationally, should receive follow-up treatment. • Counselling, post-exposure testing and medical evaluation should be provided to all exposed people, regardless of whether they receive PEP or not. • If taking ARVs patients should be followed up for adherence and possible side-effects of ARVs (e.g. nausea or diarrhoea) should be managed symptomatically without changing the regimen. For more information, please refer to Protocol 1, Patient evaluation and antiretroviral treatment for adults and adolescents. 480 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION • After baseline testing at the time of exposure, follow-up testing using enzyme immunoas- say should be performed at 6 weeks, 12 weeks, and 6 months after exposure, even if PEP is declined. • Direct virus assays may be performed on any exposed person who has an illness compatible with an acute retroviral syndrome, regardless of the interval since exposure. • For those who become infected with HCV after exposure to a source coinfected with HIV and HCV, extended HIV follow-up (for 12 months) is recommended (41). • If an exposed person seroconverts after PEP, he or she should be referred for HIV treatment and care services. • Psychological support should be provided and referrals suggested as appropriate, including nee- dle and syringe exchange for IDUs. • If the exposure is due to rape, it is important to arrange for counselling and support. The victim also needs to be provided with information regarding STIs, pregnancy and legal matters. • If the exposed person is a child or adolescent, or if the exposure is due to rape, it may be worth- while to cooperate with other specialists, e.g. a paediatrician or a rape counsellor. • Health care providers caring for people exposed to HIV should report these cases to their health departments regardless of whether or not PEP has been prescribed, and a national PEP registry should be maintained. (See the proposed occupational exposure report in Annex 3 and the pro- posed non-occupational exposure report in Annex 4). 481 post-exposure prophylaxis for hiv infection V. Prevention of occupational and nosocomial exposure After occupational exposure, it is recommended to evaluate work place safety measures and strengthen standard precautions measures. The importance of primary prevention in any setting where HIV can be transmitted should be re- inforced in every programme that provides PEP. Health care workers (HCW) and other exposed workers should receive appropriate information on PEP availability and the reference centres. It is important to underline that PEP is not ever likely to be 100% effective, and thus it should always be integrated into a larger HIV exposure prevention strategy based on standard precaution principles. Quality control and evaluation of safety conditions at work should be re-evaluated after exposure. Provided that the procedures for preventing occupational transmission of bloodborne viruses are adhered to at all times, most clinical procedures pose no risk of transmission of HIV from an in- fected HCW to a patient (42).5 1. Standard precautions Standard precautions are infection control measures that reduce the risk of transmission of blood- borne pathogens through exposure to the blood or other body fluids of patients and health care pro- viders. As it is not possible to identify everyone who may be infected with a bloodborne pathogen, protecting HCWs and patients against HIV and hepatitis viruses should be based on the concept that all patients and HCWs are assumed to be infected with bloodborne diseases. The application of standard precautions requires that all blood and other body fluids should be re- garded as potentially infectious and appropriate protective action taken. To help protect HCWs and patients from bloodborne infections, including HIV, WHO advises that standard infection control precautions be used, as follows. • Wash hands with soap and water before and after procedures. • Use protective barriers such as gloves, gowns, aprons, masks and goggles for direct contact with blood and other body fluids. • Disinfect instruments and other potentially contaminated equipment. • Handle soiled linen properly (see next section). • Using new, single-use injecting equipment for all injections is highly recommended. • Sterilizable injections should only be considered if single-use equipment is not available and if their sterility can be documented with time, steam and temperature indicators. • Discard contaminated sharps immediately without recapping in puncture- and liquid-proof con- tainers that are closed, sealed and destroyed before completely full. • Document the quality of sterilization for all medical equipment used in percutaneous procedures (45). Please see Annex 5 for a checklist of standard precautions for HCWs. 2. Reducing occupational exposure in health care settings 2.1. Basic preventive measures and workplace practices In addition to standard precautions, workplace practices should be instituted and followed to re- duce exposure to bloodborne pathogens and other infectious materials. Avoid accidental injuries 5 The overall risk of an infected HCW transmitting HIV to a patient is low. Worldwide, only two possible reports of such transmission have been reported, both during exposure-prone procedures (43, 44). 482 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION and exposure routes that can transmit bloodborne infections. The following guidelines should be adhered to: • Institute procedures to ensure and monitor compliance with safety measures. • Only allow health care professionals to perform a duty involving exposure to body fluids if they have undergone training and education in infection control and preventive measures, including the correct methods for cleaning up accidental spills of blood and other body fluids. • Avoid splashing, spraying, splattering and generating droplets of blood or other potentially in- fectious materials. • Clean all equipment and environment surfaces immediately after contact with blood or other potentially infectious materials. • Place potentially infectious specimens in properly labelled containers that will prevent leakage during collection, handling, processing, storage, transport and shipping. Use a secondary con- tainer if the primary container becomes contaminated or punctured. • Hand-washing is essentisal. ° Wash hands and any other exposed skin with soap and water before and after procedures, including after removal of gloves and other personal protective equipment or attire. ° Following the contact of body areas with blood, other potentially infectious materials or con- taminated surfaces, wash hands and flush mucous membranes with water immediately or as soon as feasible. ° Use soap and running water. If running water is not available, use an appropriate antiseptic hand cleanser and clean towels or antiseptic towelettes, followed by regular hand-washing as soon as feasible. ° If minimal skin lesions are already present on hands (e.g. cuts), they need to be properly ad- dressed before using gloves. Bear in mind that glove use requires consideration of additional safety precautions (see Annex 5). • Proper handling of soiled linen is essential. ° Soiled linen should be handled as little as possible. ° Gloves and leak-proof bags should be used if necessary. ° Bags and containers of soiled linen should be labelled. ° Soiled linen should be cleaned and laundered outside patient areas, using detergent and hot water. • Place all regulated waste in closable, leak-proof containers. In addition, health care workers must observe the following restrictions: • Do not eat, drink, smoke, apply cosmetics, apply lip balm or handle contact lenses in work areas where occupational exposure to bloodborne pathogens is likely. • Do not keep food and drink in refrigerators or other locations where blood or other potentially infectious materials are present. • Never use the mouth to pipette or suction blood or other potentially infectious materials. • Never use hands to pick up broken glassware that may be contaminated. • Do not bend, recap, break or remove contaminated needles or other contaminated sharps. • Never use hands to reach into, open, empty or clean reusable sharps containers (46). 2.2. Protective material and equipment Protective equipment and controls should be instituted in all health care settings. To prevent trans- mission of bloodborne pathogens, the following precautions should be taken: • Protective equipment and clothes should be made available to and worn by all workers who come into contact with blood or body fluids, including: ° gloves ° liquid-resistant gowns ° face and eye protection. 483 post-exposure prophylaxis for hiv infection • Safety measures for needles and syringes include the following. ° Use new, single-use, self-sheathing needles or other new disposable injecting equipment for all injections. ° Only consider sterilizable injections if single-use equipment is not available and if the steril- ity can be documented with time, steam and temperature indicators. ° Use needleless intravenous (IV) access systems. ° Use a mechanical device that protects the hand or a safe one-handed technique if needle re- capping or removal is absolutely necessary. ° In general, containers for sharps should be wall-mounted when not in use to avoid accidents that may occur from patients (especially children) playing with or trying to open them. • Safety measures for other sharps include the following. ° Discard contaminated sharps immediately and without recapping in puncture- and liquid- proof containers that are closed, sealed and destroyed before completely full. ° Position sharps disposal containers so that they are easily accessible and maintained upright throughout use. ° Replace sharps disposal containers regularly and do not allow them to overfill. ° Before moving a container of contaminated sharps, close it completely. Place it in a second- ary container if leakage is possible. • Safety measures for dental instruments, devices and equipment include the following (47). ° Follow normal heat-sterilization procedures for surgical instruments, periodontal scalers, scalpel blades, surgical dental burs, dental mouth mirrors, amalgam condensers, reusable dental impression trays and dental handpieces. ° If disinfecting instruments or other equipment that is heat-sensitive, use high-potency disin- fectant. ° Devices connected to the dental water system that enter a patient’s mouth (e.g. handpieces, ultrasonic scalers, air abrasion devices and air/water syringe tips) should operate for a mini- mum of 20–30 seconds after each patient to discharge water and air and flush out any patient material. ° Where possible, use dental units that prevent retraction of oral fluids. ° Components that are permanently attached to dental unit waterlines (e.g. the handles and den- tal unit attachments of saliva ejectors, high-speed air evacuators and air/water syringe tips) should be covered with impervious barriers that are changed after each use. • Appropriate first-aid equipment should always be readily available for dealing with spilled body fluids, and staff should be trained to institute safety precautions following any accident. • Containers appropriate for waste disposal should always be available – as should guidelines for such disposal. 2.3. Technological controls Technological controls can help isolate and remove bloodborne pathogens from the workplace. • Document the quality of the sterilization for all medical equipment used for percutaneous proce- dures. • Disinfect instruments and other contaminated equipment. • Before servicing or shipping, decontaminate any equipment that is contaminated with blood or other potentially infectious materials. If decontamination is impossible, attach a label that states which portions of the equipment remain contaminated. • Set up quality control charts to monitor standard precautions in technical procedures and instru- ment use. 484 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION 2.4. Personal protective equipment and its use If the potential for occupational exposure still remains after an HCW uses up to date technological controls and standard work practice precautions, the employer must also provide personal protec- tive equipment (PPE). This equipment must be provided in a readily accessible location and at no cost to the HCW. • Gloves include special gloves if an HCW is allergic to conventional medical gloves. ° Single-use gloves should not be reused, nor should reusable gloves that show signs of dete- rioration. ° Petroleum-based lubricants should not be used, as they can eat through latex rubber. • Gowns/laboratory coats should be used. ° Outer garments should be worn in occupational exposure situations. ° Surgical caps/hoods and shoe covers/boots should be worn only if potential gross contamina- tion of the head or feet is anticipated. • Face shields/masks/eye protection should be used. ° Chin-length face shields or masks should be worn in combination with eye protection devices and side shields whenever splashes, spray, spatter or droplets of blood or other potentially infectious materials may be generated. ° Regular eye-glasses do not provide sufficient protection against bloodborne contaminants. Personal protective equipment must not permit blood or other potentially infectious materials to pass through to or reach work clothes, street clothes, undergarments, skin, eyes, mouth or other mu- cous membranes under normal conditions of use during the time in which the protective equipment will be used. Heavy gloves and protective clothing and appropriate training should be provided for all cleaners and waste disposal handlers. If a protective garment is penetrated by blood or another potentially infectious material, it should be removed as soon as possible. Wash the affected area with soap and water. Remove all PPE prior to leaving the work area and place it in a designated receptacle. Employers are responsible for clean- ing, laundering, repairing, replacing and disposal of used PPE. 485 post-exposure prophylaxis for hiv infection VI. Suggested minimum data to be collected at the clinical level Based on the proposed occupational and non-occupational reporting forms (Annexes 3 and 4), the clinical level should aggregate the detailed information about patients requiring PEP, receiving PEP and outcomes (patients who become infected or not). 486 HIV/AIDS TREATMENT AND CARE CLINICAL PROTOCOLS FOR THE WHO EUROPEAN REGION Annex 1. Informed consent form for source person (Informed consent to perform an HIV test and authorization for release of HIV-related information for pur- poses of providing post-exposure care to a person accidentally exposed occupationally or non-occupation- ally*) A person has been exposed to your blood or a body fluid in a manner that may pose a risk for the transmission of a bloodborne infection. Many individuals may not know whether they have a bloodborne infection because people can carry these viruses without having any symptoms. We are therefore asking for your consent to test for the presence of human immunodeficiency virus (HIV). You will also be tested for hepatitis B virus (HBV) and hepatitis C virus (HCV). HIV testing is voluntary and requires your consent in writing; consent can be withdrawn for the test at any time. Your blood will be tested by a rapid or enzyme immunoassay serological test. The test result will be used to help determine whether the exposed person is actually at risk for HIV and requires treatment for that exposure. We will inform you of the test results, helping you understand their implications as well as assisting you in accessing any services you may need. Meaning of HIV test results You also are being asked to authorize the release of confidential HIV-related information related to this re- quest to the health professional, named below, who is treating the exposed person. This release is necessary to provide appropriate care and to counsel the exposed person about his or her risk of becoming infected and possibly infecting others. Confidential HIV-related information can only be given to persons you allow to have it by signing a release. These individuals are prohibited by law from subsequently disclosing these test results or your identity. ____________________________________________________________________ Name of exposed person’s health care provider to whom HIV test result will be disclosed: Prior to executing this consent, you will be counselled about the implications of HIV testing and your confi- dentiality protections under the law. I understand the purpose for which I am being asked to submit a specimen for HIV testing. My ques- tions about the HIV test were answered. I agree to be tested for HIV, and I authorize the release of this information to the health care provider for the exposed person. This release is effective for one year after the date listed below. ____________________________________________________________ ____________________________ Name of person to be tested Date _________________________________________________________________________________________ Signature of the person to be tested, or of the person consenting if different from the person to be tested I provided pretest counselling.

Standard precautions – an aide memoire5 Infection control standard precautions in health care Background Standard precautions are meant to reduce the risk of transmission of bloodborne and other pathogens from both recognized and unrecognized sources. They are the basic level of infection control precautions which are to be used, as a minimum, in the care of all patients. Hand hygiene is a major component of standard precau- tions and one of the most effective methods to prevent transmission of pathogens associated with health care. In addition to hand hygiene, the use of personal protective equipment should be guided by risk assessment and the extent of contact anticipated with blood and body fluids, or pathogens. In addition to practices carried out by health workers when providing care, all individuals (including patients and visitors) should comply with infection control practices in health-care settings. The control of spread of pathogens from the source is key to avoid transmission. Among source control measures, respiratory hygiene/ cough etiquette, developed during the severe acute re- spiratory syndrome (SARS) outbreak, is now considered as part of standard precautions. Worldwide escalation of the use of standard precautions would reduce unnecessary risks associated with health care. Promotion of an institutional safety climate helps to improve conformity with recommended measures and thus subsequent risk reduction. Provision of adequate staff and supplies, together with leadership and education of health workers, patients, and visitors, is critical for an enhanced safety climate in health-care settings. Checklist Health policy Promote a safety climate. Develop policies which facilitate the implementation of infection control measures. Hand hygiene Perform hand hygiene by means of hand rubbing or hand washing (see overleaf for detailed indications). Hands should always be washed with soap and water if hands are visibly soiled, or exposure to spore-form- ing organisms is proven or strongly suspected, or after using the restroom. For other indications, if resources permit, perform hand rubbing with an alcohol-based preparation. Ensure availability of hand-washing facilities with clean running water. Ensure availability of hand hygiene products (clean water, soap, single use clean towels, alcohol-based hand rub). Alcohol-based hand rubs should ideally be available at the point of care. Personal protective equipment (PPE) ASSESS THE RISK of exposure to body substances or contaminated surfaces BEFORE any health-care activity. Make this a routine! Select PPE based on the assessment of risk: clean non-sterile gloves. clean, non-sterile fluid-resistant gown. mask and eye protection or a face shield. Respiratory hygiene and cough etiquette Education of health workers, patients and visitors. Use of source control measures. Hand hygiene after contact with respiratory secretions. Spatial separation of persons with acute febrile respi- ratory symptoms.Important advice • Promotion of a safety climate is a cornerstone of pre- vention of transmission of pathogens in health care. • Standard precautions should be the minimum level of precautions used when providing care for all patients. • Risk assessment is critical. Assess all health-care activities to determine the personal protection that is indicated. • Implement source control measures for all persons with respiratory symptoms through promotion of respiratory hygiene and cough etiquette. 5 The overall risk of an infected HCW transmitting HIV to a patient is low. Worldwide, only two possible reports of such transmission have been reported, both during exposure-prone procedures (43, 44). Source: WHO (48). 493 post-exposure prophylaxis for hiv infection Infection control standard precautions in health care kEy ElEMENTS AT A glANCE 1. Hand hygiene1 Summary technique: Hand washing (40–60 sec): wet hands and apply soap; rub all surfaces; rinse hands and dry thoroughly with a single use towel; use towel to turn off faucet. Hand rubbing (20–30 sec): apply enough product to cover all areas of the hands; rub hands until dry. Summary indications: Before and after any direct patient contact and be- tween patients, whether or not gloves are worn. Immediately after gloves are removed. Before handling an invasive device. After touching blood, body fluids, secretions, excre- tions, non-intact skin, and contaminated items, even if gloves are worn. During patient care, when moving from a contami- nated to a clean body site of the patient. After contact with inanimate objects in the immediate vicinity of the patient. 2. gloves Wear when touching blood, body fluids, secretions, excretions, mucous membranes, nonintact skin. Change between tasks and procedures on the same patient after contact with potentially infectious material. Remove after use, before touching non-contaminated items and surfaces, and before going to another patient. Perform hand hygiene immediately after removal. 3. Facial protection (eyes, nose, and mouth) Wear a surgical or procedure mask and eye protection (face shield, goggles) to protect mucous membranes of the eyes, nose, and mouth during activities that are likely to generate splashes or sprays of blood, body fluids, secretions, and excretions. 4. gown Wear to protect skin and prevent soiling of clothing during activities that are likely to generate splashes or sprays of blood, body fluids, secretions, or excretions. Remove soiled gown as soon as possible, and perform hand hygiene. 5. Prevention of needle stick injuries2 Use care when: handling needles, scalpels, and other sharp instru- ments or devices cleaning used instruments disposing of used needles. 6. Respiratory hygiene and cough etiquette Persons with respiratory symptoms should apply source control measures: cover their nose and mouth when coughing/sneezing with tissue or mask, dispose of used tissues and masks, and perform hand hygiene after contact with respiratory secretions. Health care facilities should: place acute febrile respiratory symptomatic patients at least 1 metre (3 feet) away from others in common waiting areas, if possible. post visual alerts at the entrance to health-care facili- ties instructing persons with respiratory symptoms to practise respiratory hygiene/cough etiquette. consider making hand hygiene resources, tissues and masks available in common areas and areas used for the evaluation of patients with respiratory illnesses. 7. Environmental cleaning Use adequate procedures for the routine cleaning and disinfection of environmental and other frequently touched surfaces. 8. linens Handle, transport, and process used linen in a manner which: prevents skin and mucous membrane exposures and contamination of clothing. avoids transfer of pathogens to other patients and or the environment. 9. Waste disposal Ensure safe waste management. Treat waste contaminated with blood, body fluids, secretions and excretions as clinical waste, in accordance with local regulations. Human tissues and laboratory waste that is directly associated with specimen processing should also be treated as clinical waste. Discard single use items properly. 10. Patient care equipment Handle equipment soiled with blood, body fluids, secretions, and excretions in a manner that prevents skin and mucous membrane exposures, contamination of clothing, and transfer of pathogens to other patients orthe environment. Clean, disinfect, and reprocess reusable equipment appropriately before use with another patient. 1 For more details, see: WHO guidelines on hand hygiene in health care: (http://www.who.int/patientsafety/information_centre/ghhad_download/en/index.html). 2 The SIGN Alliance: (http://www.who.int/injection_safety/sign/en/).

HIV/AIDS treatment and care Clinical protocols for the WHO European Region Protocol 1: Patient Evaluation and Antiretroviral Treatment for Adults and Adolescents Update 18 July 2008 Page 18: New section 4.4.5, please add the following: (For the full report on ART failure and strategies for switching ART regimens see box) 4.4.5 Revised definitions of ART failure and strategies for switching ART regimens Definition of first-line failure Virological failure • primary virological failure – no response by patient, i.e., VL does not decrease to < 50 copies/ml on two different occasions after more than six months of ART; • secondary virological failure – viral rebound, i.e., VL > 50 copies/ml confirmed. The virological failure scenarios are not necessarily indicators for a switch. Immunological failure (CD4 cell count, if VL is unavailable) • 25% drop from the patient’s maximum level or • failure to increase CD4 cell count > 50 cells/mm³ during the first year of ART. Poor adherence issues and drug interactions need to be ruled out before failure is confirmed. Basing ART failure on solely clinical grounds is considered a suboptimal approach; countries are encouraged to ensure at least regular CD4 monitoring is in place. Strategies for switching ART regimens If the second-line regimen contains drugs that exclude the possibility of cross resistance of the first-line regimen the patient is currently failing, then a resistance test is not necessary in order to make the switch. Early switch: VL > 400 (> 50– < 1000)* copies/ml. • Advantages: preservation of treatment options, higher likelihood of effective response, decreased risk of non-AIDS and AIDS related events. • Disadvantages: high costs and more rapid exhaustion of ARV drug options; need for routine VL laboratory testing. Late switch (VL ≥ 1000 – 10 000 copies/ml or a 25% drop in CD4 count) • Advantage: reduced costs. • Disadvantages: greater accumulation of resistance mutations and potential enhanced transmission of resistant virus; may compromise treatment response; may limit the choice of active ARVs for second-line therapy. If at 6 months VL > 50 copies/ml, the physician before switching to second-line treatment should assess and address adherence, drug toxicity (substitute toxic drugs) and any drug interactions. The long-term implications of neither approach are known and studies comparing the switch management approaches are urgently needed. Minimum monitoring requirements • VL should be part of the standard of care of PLHIV • VL should be undertaken prior to initiation of ART and then at months 1, 3, 6 and 12; subsequent monitoring may be at longer intervals for patients responding well to treatment. • VL every 6–12 months is acceptable if there are local constraints on access or cost. • CD4 cell counts should be done prior to starting ART, then two to four times in the first year; subsequent monitoring may be twice annually. Definition of second-line failure The definition is the same as first-line failure but the management differs depending on available drug options and greater use of drug resistance testing. New drug classes should be introduced where possible. Drug resistance testing If HIV DR testing is not available after first-line failure, a blood sample should be taken and kept frozen in the event that second-line failure occurs; both blood samples, after first and second-line failure, should then be tested in deciding on a salvage regimen. * = More than 50 copies/ml, but less than 1000 copies/ml refers to the secondary definition of first-line failure, switching within this range of VL is an early switch. © World Health Organization 2008.

HIV/AIDS treatment and care Clinical protocols for the WHO European Region Protocol 4: Management of tuberculosis and HIV coinfection Update 18 July 2008 Page 140, Table 1, for previously TB-treated patients, under column "Initial phase", should read as follows: Table 1. Recommended TB treatment regimens for PLHIV with active TB Type of TB case TB treatment regimen a Initial phase b Continuation phase New TB patient HRZE 2 months c HR 4 months Previously TB-treated patient, including: • relapse • treatment after default • treatment failure d HRZES 2 months and after that HRZE 1 month HRE 5 months Chronic or MDR-TB cases (still sputum-positive after supervised re-treatment) A specially designed regimen, whether standard or ad hoc E: ethambutol; H: isoniazid; R: rifampicin; S: streptomycin; Z: pyrazinamide. a Daily TB treatment is recommended for HIV-positive patients with active TB. b Direct observation of drug intake is recommended during the entire course of therapy, particularly in the initial phase. c Streptomycin may be used instead of ethambutol. In meningeal TB, ethambutol should be replaced by streptomycin, which diffuses more in the meninges. d Whenever possible, drug sensitivity testing should be done to enable an individualized treatment regimen. © World Health Organization 2008.

HIV/AIDS treatment and care Clinical protocols for the WHO European Region Protocol 11: Peadiatric HIV/AIDS treatment and care Update 18 July 2008 Page 399, section 4 ART in infants and children, paragraph 2 the first sentence should read as follows: Children of 12 months and older should be started on ART when they have either an AIDS- defining illness or severe immunological failure (see Table 1). Page 400, Table 2 second column should read <12 months, under this column it should read as follows: Treat all irrespective of CD4 level Table 2 should look as follows: Table 2. CD4 criteria for initiation of ART Immunological marker Recommended threshold levels for initiating ART <12 months 12–35 months 36–59 months ≥5 years a CD4 % and/or CD4 count Treat all irrespective of CD4 level ≤20% (≤750 cells/mm 3 ) ≤15% (≤350 cells/mm 3 ) ≤200 cells/mm 3 (≤15%) a Starting at 5 years of age CD4 cell count is a more accurate indication for initiation of treatment.

Page 401, Table 3 the title of the table and first table note should read as follows: Infant/child with confirmed HIV infection ≥ 12 months of age Confirmation = serological or virologic depending on age < 12 months of age & any stage Treat & stabilize acute conditions & opportunistic infections Assess clinical stage WHO Paediatric Clinical Staging Stage 4 % CD4 is preferred if available Stages 1, 2, 3 CD4 Assessment Available Yes No ≥12 months - <35 months: %CD4 ≤20 or <750 mm3 ≥36 months - <59 months: %CD4 ≤20 or <350 mm3 ≥5years: %CD4 ≤15 or <200 mm3 Initiate First Line ART Stage 3 Stage 2 Stage 1 Do not start ART Table 3. First-line ART regimens for non-exposed infants and children Age ARV classes ARV combinations <3 years (or <10 kg) 2 NRTIs + 1 NNRTI ABC (or ZDV) + 3TC a + NVP b ≥3 years 2 NRTIs + 1 NNRTI ABC (or ZDV) + 3TC a + EFV b, c a The ABC + 3TC combination is very effective for ART-naive children. PENTA 5 follow up data clearly confirms the superiority of this regimen (http://www.ctu.mrc.ac.uk/penta/trials.htm (32, 33). D4T should be avoided due to the increased risk of lipodystrophy (34, 35). b EFV is not currently recommended for children <3 years of age or < 10 kg, and should not be given to post-pubertal girls who are either in the first trimester of pregnancy or are sexually active and not receiving adequate contraception. EFV is preferred over NVP in children older than three years. c NVP should be avoided in post-pubertal girls (considered adults for treatment purposes) with baseline CD4 absolute cell counts >250 cells/mm 3 . Page 401, subsection 4.4 the last sentence should read as follows: The frequency of such transmission has not been well documented; however, direct and indirect data show compromised response to NVP based regimens after NVP exposure in infants; consequently, NVP-based therapy should be used only if protease inhibitors are not available, affordable or feasible. Page 401, subsection 4.4.1 the last bullet point should read as follows: • The PI/r-based first-line regimen (2NRTIs+LPV/r) is recommended, where available and affordable (Report of the WHO Technical Reference Group, Paediatric HIV/ART Care Guideline Group Meeting, WHO Headquarters, Geneva, Switzerland, 10-11 April 2008, http://www.who.int/hiv/pub/meetingreports/ art_meeting_april2008/en/index.html). Page 402, subsection 4.4.2 the last bullet point should read as follows: • The PI/r-based first-line regimen (2NRTIs+LPV/r) is recommended, where available and affordable.
