Foreword The Ministry of Health and Social Welfare has realized the plight of the children infected with HIV and AIDS in the country and is thus stepping up efforts to reduce the number of children who are infected with HIV through mother to child transmission. Prevention of mother to child transmission is therefore a priority to ensure that children born to HIV positive mothers are HIV free and healthy. The clinical management of children infected with HIV and AIDS has been difficult due to the lack of comprehensive guidelines for paediatric HIV and AIDS treatment, lack of capacity among health workers to provide quality care for these children and inadequate choice of paediatric ARV drugs from which to choose from. These paediatric guidelines have been developed through consultations with the medical personnel in the different health care facilities in the country and with partners involved in improving the health of children in the country. It is therefore based on experience of paediatric ART in resource-limited settings and considers what works for the situation of Swaziland. The new guidelines also take into account the new developments in paediatric HIV and AIDS in the world, and considers the use of new types of ARV drug combinations that are expected to be easier to adhere to by children on ART. Also covered in these guidelines are issues around the care and treatment of adolescents, as the number of perinatally HIV infected children growing into adolescence is increasing. It is also worth noting that as this is an evolving era, new information is constantly becoming available and as this happens, the information will be made available to the users of these guidelines. The understanding of these guidelines will be further complimented by capacity building of health workers on paediatric HIV and AIDS. It is expected that trainings of health workers will continue to cover a greater percentage of the health workers involved in ART service delivery in the country, which will help to improve the care of children with HIV and AIDS in Swaziland. Finally, we would like to thank the dedicated team that worked tirelessly to produce these paediatric guidelines, the first of its kind in Swaziland.

Chapter 1: Introduction About 2.3 million children below the age of 15 years are living with HIV/AIDS and 2.1 million of them are in SubSaharan Africa. There are 16 000 children living with HIV/AIDS in Swaziland and an estimated 65 000 AIDS orphans (UNAIDS 2004 Report). Swaziland's infant mortality rate (IMR) is 108 per 1000 live births and under 5 mortality is 156 per 1000 live births (2004) (UNICEF SOWC 2006). HIV related mortality contributes significantly to both the IMR and Under 5 mortality. It is paramount that the HIV prevention, treatment and care of children are scaled up if significant reduction in childhood mortality is to be achieved. The majority of children get HIV infection through mother to child transmission (MTCT). This accounts for >95% of infections in children. There is 10% risk of transmission in utero, 20% intrapartum (labour and delivery), and 15 - 20% post-partum during breastfeeding. In Swaziland, the HIV prevalence among pregnant women is 39.2% (National surveillance, 2006) and the annual number of deliveries is estimated to be about 40,000. Therefore approximately 17,000 babies will be born to HIV-infected mothers and an estimated 6,800 of these will be HIV infected. Even HIV-negative infants born to HIV-infected mothers have a 2- to 5-fold increased risk of mortality as a direct consequence of the mother's HIV infection (either severe disease or early death). Prevention of HIV infection is paramount if efforts to reduce HIV in children are to succeed. Swaziland has adopted the WHO strategic 4-prong approach to the prevention of HIV infection in women and infants: ? Prong 1: primary prevention of HIV-infection ? Prong 2: prevention of unintended pregnancies among HIV positive women ? Prong 3: Reduction of MTCT among HIV positive pregnant women ? Prong 4: Care and support for HIV positive women and their families Details on the implementation of these 4 prongs can be found in the national PMTCT guidelines. The other modes of HIV transmission to children include: ? Sexual abuse by infected person ? HIV contaminated blood and blood products ? Use of non-sterile instruments ? Traditional scarifications ? Wet nursing by an infected person (breastfeeding by woman other than the biological mother)

Chapter 2: Care of the HIV exposed child An HIV-exposed infant is 1. An infant who is born to an HIV-positive mother or 2. An infant who tests positive for HIV antibodies even if the mother's status is unknown HIV exposure can be established by: 1. Confirming the HIV status of the mother (either tested during PMTCT) 2. If status of the mother is unknown and mother is available: counsel and test mother to confirm HIV exposure status of child 3. If the mother is not available: counsel the caregiver and do a rapid test on the child to confirm the HIV exposure status (for children < 18 months)
Children above 18 months who are HIV antibody positive are HIV infected HIV exposed infants and children should be followed up and managed according to The TenPoint Package for Comprehensive Paediatric AIDS Care: 1. Confirm HIV status as early as possible 2. Monitor the child's growth and development 3. Ensure that immunizations are started and completed according to the recommended schedule 4. Provide prophylaxis for opportunistic infections (PCP, MAC, and TB) 5. Actively look for and treat infections early 6. Counsel the mother and family on
Optimal infant feeding to minimize Maternal to Child Transmission (MTCT), prevent malnutrition and promote growth and development
Good personal and food hygiene to prevent common infections. Encourage the caretaker to seek prompt treatment for any infections or other health related problems
When the child should be followed up 7. 8. 9. 10.
Conduct WHO staging for the infected child Offer antiretroviral (ARV) treatment for the infected child, if eligible Provide psychosocial support to the infected child and mother Refer the infected child for higher levels of specialized care if necessary, or for other social- or community-based support programs

2.1. Infant Diagnosis
HIV exposed children have maternal antibodies passively transferred to them from their mother. These maternal antibodies are no longer detectable in the baby after 18 months of age. The tests used to detect antibodies are the Rapid and ELISA tests. If performed before 18 months, these tests may detect maternal and/or infant antibodies and therefore cannot confirm infection in the baby. However, antibody tests done after 18 months detect infection in the baby as maternal antibodies should have been cleared. In non breastfeeding infants or after cessation of breastfeeding for at least 3 months, an HIV antibody test should be done at 12 months; if negative then the baby is not HIV infected. A repeat antibody test should be done at 18 months. Ideally virological testing should be done for definitive diagnosis of HIV infection in children < 18 months of age. This will confirm infection if the test is positive. A negative test only confirms absence of infection if the child is not breastfeeding or at least 3 months after cessation of breastfeeding. Breastfeeding babies continue to be at risk of HIV transmission through breast milk. The virological tests that can be done are HIV DNA PCR, HIV RNA PCR, and ICD p24. Availability of these tests is still limited in Swaziland. HIV DNA PCR is the test of choice for the Ministry of Health and Social Welfare and will be made available in 2007. These tests are more reliable if done from the age of 6 weeks (usual post natal visit). Virological tests should therefore be done as early as possible from 6 weeks of age. The purpose of early infant diagnosis is to identify children who are HIV infected, so that they can start ART early. Waiting until 18 months to confirm the diagnosis using antibody tests is often too late. In the absence of virological testing, a presumptive HIV diagnosis based on clinical criteria can be made pending a confirmatory test. In all circumstances, regular close clinical monitoring of HIV exposed infants is critical. Do not delay referral to an ART centre for CD4 assessment and care and treatment if the child has The purpose of early infant ? growth retardation (slower than expected diagnosis is to identify HIV growth or failure to thrive) infected children, so that they ? delayed development or loss of can start care and treatment developmental milestones ? clinical signs or symptoms suggestive of AIDS
A. Diagnosis of HIV infection in children less than 18 months old Figure 1 and Figure 2 on pages 6 and 7 are flow charts that assists with the steps to take to confirm HIV infection in children <18 months depending on whether or not they are breastfeeding if virological tests are available. In absence of virological testing, a presumptive diagnosis can be made based on clinical criteria

B. Establishing HIV infection with antibody testing in children 18 months of age and older In children older than 18 months of age, do the following: 1. Confirm HIV infection using antibody testing. 2. A child that is confirmed HIV antibody positive (i.e. two positive Rapid tests such as Determine and Unigold or positive ELISA) is HIV infected. 3. Refer all HIV infected children for treatment, care and support 4. A negative antibody test implies that the child is not HIV infected. However, if the child is still breastfeeding, she/he is still exposed to HIV infection, so repeat HIV antibody testing at least 3 months after complete cessation of breastfeeding.

2.2 Cotrimoxazole Prophylaxis
Cotrimoxazole prophylaxis prevents Pneumocystis jiroveci Pneumonia (PCP), toxoplasmosis and other bacterial infections in HIV positive children. All infants exposed to HIV must receive prophylactic cotrimoxazole.
A. Who Should Receive Cotrimoxazole and for how long?
All HIV exposed infants (all infants whose mothers are known to be HIV positive) § From 6 weeks of age § Until HIV infection has been definitely ruled out (see infant diagnosis) AND the child is no longer breastfeeding
All HIV infected children below 5 years of age § From time of HIV diagnosis All HIV infected children > 5 years of age § From time of HIV diagnosis § With clinical signs and symptoms suggestive of HIV infection § Indefinitely if there is no ART available for the child § Until the child has evidence of immune restoration under ART (CD4 > 350 at least 6 months after ART initiation – see chapter on ART)
B. Cotrimoxazole Dosage The dosage for Cotrimoxazole prophylaxis is given in table 1. Dosage can be either according to weight or according to age. Give Cotrimoxazole syrup or Cotrimoxazole tablets (the tablets can be crushed). Once daily Weight (kg)

C. Contra Indications To Use Of Cotrimoxazole Cotrimoxazole should not be given to children with: Sulfa allergy Severe renal or liver insufficiency
D. Information For Parents Cotrimoxazole prevents serious infections. It helps your child feel better and live longer. It is not an antiretroviral treatment. It does not cure AIDS. The dose will increase when your child grows. Use either a spoon or a syringe to measure the dose You can crush a tablet and mix it with food before giving it to your child You can give cotrimoxazole with or without food Some children develop adverse reactions to cotrimoxazole. Bring the child back if he/she develops a serious rash
E. Reactions To Cotrimoxazole Stop cotrimoxazole if the child has a severe reaction. Dapsone 2mg/kg can be used as an alternative to cotrimoxazole. Desensitisation can be done with cotrimoxazole being introduced gradually under medical supervision. WHO recommends desensitization in adolescents but not in younger children. Desensitization should not be attempted in individuals with a history of Grade 4 severe reaction to cotrimoxazole or any other sulfa drugs.
2.3 Suggested follow up schedule for the HIV-exposed child
Follow up should be well planned. Exposed children should be followed up monthly in their first year of life. Always check the mother's own health during the follow up visits and ensure that she also gets appropriate care and support. Encourage the mother to come with her other children on her next visit. Assess and provide care to the siblings as needed. The suggested follow up visit schedule is provided in table 2 (see next page):

Exposed children need to be referred for assessment (clinical and CD4) when they: Have a growth retardation (slower than expected growth or failure to thrive) Have delayed development or lose developmental milestones Have clinical signs or symptoms suggestive of AIDS Try to establish if an infant is infected as early as possible, to provide appropriate care and treatment.
2.4 Natural History of HIV in children The natural history of HIV in children (without any intervention) shows that the progression of disease differs in children. Three distinct groups have been identified.
A. Rapid Progressors – 25% These children develop early onset CNS involvement and OIs with CD4 lymphopenia in the first year of life. The majority of them die within the first year of life and almost all of them by the second year of life.
B. Intermediate Progressors – 50 -70% These children are asymptomatic for the first 4/5 years of life.
C. Slow Progressors – 5-10% These children are asymptomatic for 8/10 years. It is therefore important to continuously assess children of any age for HIV infection, have a high index of suspicion, and consider provider initiated counselling and testing and cotrimoxazole prophylaxis. Mortality in HIV infected children is very high. Studies in resource-constrained countries indicate that the risk of death is 52.5% at 2 years and 66-75% at 5 years in untreated HIV-infected infants. Delayed diagnosis of HIV infection, poor nutrition, and high levels of severe bacterial respiratory and gastrointestinal tract infections are likely reasons for the higher early mortality. The majority of children are Failure to identify HIV- infected children early results in the following HIV/AIDS mortality rates based on age (Newell et al, 2004 and Spira et al, 1999) At 1 year At 2 year At 5 year At 10 years

either rapid or intermediate progressors.
It is important that infected children are identified early and given appropriate care, treatment and support
Chapter 3: Care of the HIV infected Child 3.1.Identify HIV infected children
HIV infected children can be identified through: PMTCT program § Exposed children with growth or developmental retardation § Symptomatic children identified on clinical examination during follow up of the exposed child. § Asymptomatic children who had a positive virological test § positive rapid test or ELISA after 18 months (If breastfeeding repeat the ELISA 612 wks after cessation of breastfeeding) Routine medical care via Provider-Initiated Testing and Counselling § Symptomatic children identified during routine clinical care on inpatients admissions or outpatients visit e.g. immunization visits or any other medical visits. PEP program. § Confirmed HIV positive children identified during post exposure prophylaxis care following sexual abuse or other exposures. The table below summarizes clinical signs that may suggest HIV infection and assist in identifying HIV infected children. Specificity for HIV Infection
Signs/conditions very specific to HIV infection
Signs/conditions common in HIV-infected children and uncommon in uninfected children
Signs/conditions common in HIV-infected children but also common in ill uninfected children
Signs/Conditions § Pneumocystis jiroveci Pneumonia (PCP) § Oesophageal candidiasis § Extrapulmonary cryptococcosis § Invasive salmonella infection § Lymphoid interstitial pneumonitis § Herpes zoster (shingles) with multi-dermatomal involvement § Kaposi’s sarcoma § Lymphoma § Progressive multifocal encephalopathy § Severe bacterial infections, esp. if recurrent § Persistent or recurrent oral thrush § Bilateral painless parotid enlargement § Generalized persistent non-inguinal lymphadenopathy § Hepatosplenomegaly (in non-malaria endemic areas) § Persistent and/or recurrent fever § Neurologic dysfunction § Herpes zoster (shingles), single dermatome § Persistent generalized dermatitis unresponsive to treatment § Chronic, recurrent otitis with ear discharge § Persistent or recurrent diarrhoea § Severe pneumonia § Tuberculosis § Bronchiectasis § Failure to thrive § Marasmus
Table 4: Clinical signs and symptoms suggestive of HIV infection in children according to specificity
13
IMCI guidelines can also be used to identify children with possible HIV infection, start them on cotrimoxazole prophylaxis and arrange for HIV testing. If identified using the IMCI algorithm, these children can be further assessed, staged and provided with appropriate treatment and care (see IMCI guidelines for further details). Consider symptomatic HIV Infection in every child found to have: Recurrent diarrhoea or persistent diarrhoea Acute ear infection (with pus discharge) Fever for more than 30 days Low weight/growth faltering.
Ask
Has the child had more than one episode of severe chest infection requiring antibiotics (pneumonia) in the past 3 months? Has the child had one or more episodes of persistent or acute diarrhoea in the past 3 months?
Any Three signs: Symptomatic HIV infection
Has the child had fever (recurrent or intermittent) for more than one month? Does the child have acute or chronic or recurrent ear infection? History or evidence of past or present herpes zoster?
Classify As
History or evidence of severe seborrheic dermatitis? History of TB in the child? Mother known to be HIV positive?
Then look and feel Has the child a low weight-for-age or is growth faltering? (weight curve flat or falling for 2 consecutive months)
Two signs or fever: HIV infection unlikely
Any enlarge lymp glands in more than one of the following sites: neck, axillae groins? Is there oral thrush? Is there Parotid enlargement?
Figure 6: IMCI check list for HIV infection in children
3.2 Clinical staging
Always stage HIV-infected children when you assess them, at every visit. This helps to: See the clinical progression of disease Assists with decision making on commencement of ART even without CD4 counts. Assists in assessing clinical improvement on ART.

3.3 Immunological staging HIV infected infants and children should be monitored regularly with CD4 cell counts/percentages to measure HIV associated immunodeficiency. If CD4 cell counts/percentages are not available, then Total Lymphocyte Counts (TLC) can be used.
A. CD4 Cell Counts The criteria for immunological staging for infants and children change with age. Use CD4 percentages for children 5 years and below. Age-related CD4 values Classification of HIV-associated immunodeficiency

Table 6: WHO classification of HIV associated immunodeficiency in infants and children.
Start ART in infants and children classified as severe HIV associated immunodeficiency, regardless of clinical stage. CD4 percentages below the indicated levels of severe HIV associated immunodeficiency are associated with increased risk of disease progression and mortality.
B. Total Lymphocyte Count When CD4 is not available, total lymphocyte count (TLC) can be used to complement the clinical staging in deciding to initiate ART especially in children with stage 2 disease. TLC is used in children below 8 years of age (table 7). Immunological marker Total Lymphocyte Count (TLC)

Table7: Total Lymphocyte Count (TLC) criteria of severe HIV immunodeficiency requiring initiation of ART for use in infants and children with clinical stage 2 and where CD4 measurement is not available.
A drop of TLC below the significantly increases the risk of disease progression and mortality. TLC is only used to monitor disease progression and ART initiation; it is not used for monitoring children who are already on ART.
16
3.4. Deciding when to initiate ART
Decisions on when to start ART are based on clinical (clinical staging, see table 5) and immunological (CD4 percentage TLC, see table 6 & 7) assessment. Recommendations on when to start depend on the availability of CD4 and on the age of the child.
Initiating ART is not an emergency
A. Cd4 percentage is available The following children should start ART: All children with clinical stage 3 or 4 disease, irrespective of CD4 count/percentage Children with clinical stage 1 or 2 disease, if the CD4 immunological stage is â&#x20AC;&#x153;severeâ&#x20AC;?. It is important to identify, treat and stabilise any opportunistic infection before initiating ART. It is important to obtain a baseline CD4 cell count at ART start, even if the CD4 is not required to start ART. The recommendations are summarised in Table 8 Who paediatric stage

In children less than 18 months, a presumptive diagnosis can be made as per WHO recommendation below if virological tests are not available but there is a confirmed Rapid or ELISA antibody test. HIV infection in the child should be confirmed as early as is possible. A presumptive diagnosis of severe HIV disease should be made if: The infant is confirmed HIV antibody positive; And Diagnosis of any AIDS-indicator condition(s) can be made or The infant is symptomatic with two or more of the following: Oral thrush; Severe pneumonia; Severe sepsis. Other factors that support the diagnosis of severe HIV disease in an HIV seropositive infant include: Recent HIV-related maternal death or advanced HIV disease in the mother CD4 < 20%. Confirmation of the diagnosis of HIV infection should be sought as soon as possible Table 10: Clinical criteria for presumptive diagnosis of severe HIV disease in infants and children less than 18 months of age requiring ART in situations where virological testing is not available.

3.5. ART preparation
ART should never be started as an emergency. The principles of ART are: Ensure that patient satisfies eligibility criteria Provide ongoing support to the patient and family to maintain adherence ARV drugs are not a cure for HIV. However, when both patients and healthcare providers use them properly they are associated with excellent quality of life.
ART has limitations: Drug interactions and drug resistance may decrease the potency of ARV drugs Patients must adhere to Patients on ART may develop adverse drug ART to avoid treatment reactions failure and drug Patients must take at least 95% of their pills to resistance minimize the emergence of drug resistance, which may result in treatment failure. Adherence is the key to successful therapy. In fact, patients with adherence between 70 and 89% have the highest likelihood of developing resistance. Therefore patients must be counselled on the importance of nothing less than 100% adherence. Health care workers must thoroughly assess and examine infants and children and their caregivers before starting ART. This assessment and examination includes:
A. History Identify one or two caregivers who will provide care and treatment to the child Thorough patient medical history History of TB/ household contact Nutritional assessment Psychosocial assessment Assess adherence to medication already provided to the child (e.g. CTX) Assess the accessibility of supportive processes, such as counselling services, nutritional supplements, cotrimoxazole prophylaxis and family support groups Provide care and treatment to the caregiver(s) if needed. Their health is particularly important for survival of the child.
B. Physical exam Vital signs Weight, length/height, and head circumference. Always plot the weight on the child's road to health chart (immunisation card) Complete clinical assessment including WHO staging Neurodevelopment assessment Exclude TB Sex Maturation Rating (Tanner Staging)
19
C. Initial evaluation and laboratory tests. The following laboratory investigations should be done as a baseline before ART initiation. Suggested additional baseline tests (can be done if tests are readily available)
Minimum baseline laboratory tests Hb
FBC
ALT/AST
Liver Function Tests (LFT)
Serum Creatinine
Electrolytes Pregnancy Test
CD4
Viral Load PPD, Mantoux test
Table 11: Minimum and suggested baseline laboratory tests
Do a Chest X ray (CXR) if there are clinical indications.
D. Counselling and screening Health care workers must screen and counsel patients and caregivers to ensure eligibility and readiness for ART. This usually takes a few visits and counselling sessions. A minimum of 3-4 pre-ART sessions is usually needed. Depending on different factors sometimes more sessions are needed. A general guide of visits is given below, but this should be flexible depending on individual patient needs. Counselling for the correct use of suspensions might need even more sessions. Time

Appropriate individual adherence counselling is one of the most essential elements of a successful anti-retroviral therapy program. Most occurrences of treatment failure occur due to poor adherence. Proper adherence counselling must include the following messages: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16.
Basic education about HIV, the ARVs, and their function Education that HIV is now a chronic illness and is no longer fatal if treated and monitored properly That ARV drugs, once used properly, prolong survival and improve quality of life That better adherence to a regimen guarantees greater success of therapy That ARV drugs are not a cure for HIV, that they suppress the amount of HIV to a harmless level if taken properly That once started these drugs are taken for life Explanation and demonstration of correct administration of medicines to the child, especially use of syringes or measuring spoons or caps Explanation and demonstration of practical medication management tools (pill boxes, timers (e.g. cellphone reminders), medication diaries Mechanisms to cope with HIV/AIDS Emotional support should be provided to the care givers in order to deal with issues such as importance of positive living and to ensure that the educational and recreational needs of the child are met That ARVs have known side effects that require regular follow-up with a physician Education and motivation about responsible sexual behaviour, e.g. delay of sexual encounter or abstinence, use of safer sexual practices in adolescents and sexually active youth Awareness of safer options regarding reproduction and infant feeding (for young mothers) The caretaker must realize that the child should not be limited in participating in activities unless medically contraindicated by the health care worker The importance of financial and social support of the treatment The caretaker's role in the ARV therapy and adherence
Adherence counselling and support should be provided on an ongoing basis. Key messages should be repeated regularly. Counselling and support should continue even after the child started on ART.
E. Disclosure to the child Disclosing the HIV status to the child is a very important but sensitive issue. Disclosure should start as soon as the child's development allows. Research shows that at the age of 8 years, most children can be fully disclosed to. But the decision to disclose to a child should be tailored to the individual development of the child. Children should be counselled about HIV/AIDS and ART over time in an age-appropriate manner. It becomes more important to counsel a child on HIV/AIDS and ART if (s)he starts asking more questions about the disease or begins feeling different because of the disease.
21
Problems associated with delayed disclosure to children include: Failure to adhere to medications Poor coping skills Increase in risky behaviours Greater morbidity and mortality
3.6. Eligibility for ART ART eligibility depends on both clinical and social criteria.
A. Clinical Criteria These criteria were discussed in section on page 17.
B. Social Criteria These criteria are very important in order to ensure good adherence and treatment success. Ensure that the child has a primary caregiver who is counselled and takes responsibility for giving medications, bringing the child for review and the general upkeep of the child (nutrition, immunisations etc.) The family must identify a secondary caregiver to ensure good continued support for the child if the primary caregiver is not available. Both caregivers should be properly counselled and adequately prepared for ART. Patient should be on cotrimoxazole during the pre-art preparation period and adherence counselling and monitoring should be done. If an eligible patient meets these criteria and is ready to start ART, then you can initiate ART.
3.7 Antiretroviral therapy (ART) Three main classes of anti-retroviral drugs are commonly used: 1. Nucleoside reverse transcriptase inhibitors - NRTIs 2. Non-nucleoside reverse transcriptase inhibitors - NNRTIs 3. Protease Inhibitors - PIs It is recommended to start with 2 NRTIs and 1 NNRTI. PIs are usually reserved for 2nd line following treatment failure.
22
A. Recommended First Line Regimen The recommended first line regimen for Swaziland is d4T/3TC/NVP. The preferred d4T formulation is either as part of Fixed Drug Combination tablets or as pediatric capsules. The FDC tablets for children weighing 10 kg and above are available (Triomune 30, Triviro 30) If these are not available, then the child should be given d4T suspension, provided adequate storage (refrigeration) can be guaranteed. Reconstituted d4T suspension loses its potency after 24 hours if it is not refrigerated. If the family cannot provide adequate d4T storage, then the child should be given AZT instead of d4T.
Stavudine + Lamivudine + Nevirapine d4T + 3TC + NVP Children who have been exposed to ARV drugs during PMTCT or through breastfeeding should be started on the standard recommended treatment.
B. Monitoring Patients On Art Patients on ART need to be monitored regularly. Infants should be monitored monthly for clinical and laboratory assessment, adherence and weighing. Older children should be monitored monthly for the first 3 months (clinical and laboratory assessment, adherence and weighing). If they are stable there after, their weight and adherence should be monitored on a monthly basis. Clinical and laboratory assessment can be done at 3 months intervals. Monitoring visit 2 weeks after initiating therapy 4 weeks

Clinical Monitoring Clinical monitoring and evaluation at every visit should encompass: Complete clinical examination Developmental assessment Check weight, height and head circumference and update growth charts Ensure that medicines are being correctly administered and stored Check for any drug side effects or problems with the regimen Recheck and recalculate drug doses. Review and re-enforce adherence (proper adherence counselling done by all ART team members) Re-supply ART and Cotrimoxazole Treat any inter-current infections Normal monthly growth and development monitoring in Under 5s clinic should continue. Children can be followed up more regularly if need be. Laboratory Monitoring The schedule for laboratory monitoring is as follows: Cd4 count/percentage and viral load (where available) at 6-monthly intervals after the initial one. FBC and ALT at 2, 8 and 12 weeks then 6 monthly. Other tests may be done as clinically indicated
C. Substitution Substitution is the replacement of a drug that has caused toxicity with another drug from the same class that does not have the same adverse effects. An example in our situation would be stavudine (d4T) substitution for zidovudine (AZT) if anaemia occurs with AZT. The table on page 24 summarizes the toxicities of the first line drugs and the suggested substitutions. ART Toxicities/ Adverse Events (See Appendix 3) Moderate to severe ART toxicities may need substitution of the ARV responsible for the toxicity. This is not the same as changing (or switching) to 2nd line for treatment failure. Substitution can compromise future 2nd line regimens. Be careful in choosing the right drug. Contact an HIV paediatric specialist if in doubt.

Table 14: Severe toxicities in infants and children associated with specific first-line ARV drugs and suggested firstline drug substitutions.
D. Treatment Failure: When To Switch (change) To 2nd Line Treatment Factors that contribute to treatment failure Poor adherence Inadequate drug levels Prior existing drug resistance or inadequate potency of the drugs chosen Genetic differences in drug metabolism Use of mixed formulations of same drug WHO recommends using clinical criteria to identify treatment failure. When Cd4 count/percentage is available, it is used in addition to the clinical assessment to define treatment failure. Before considering treatment failure it is important to ensure that: the child has received therapy for at least 6 months (24 weeks) adherence has been assessed as being optimal any intercurrent opportunistic infections have been identified and treated the child is receiving adequate nutrition When treatment failure is confirmed, it is necessary to switch to a second-line regimen
Treatment failure is identified based on clinical criteria supported by CD4 criteria
25
Treatment failure Based on Clinical Criteria Treatment failure should be considered when clinical symptoms that are suggestive of a more severe clinical stage develop in a child on therapy for at least 6 months. This usually presents as development of new or recurrent WHO Paediatric Clinical stage T3 or T4 events whilst the child is on ART (see table 5 on page 15). Lack of or decline in growth rate in children who show initial response to treatment (T3 or T4) Loss of neurodevelopmental milestones or development of encephalopathy (T4) Occurrence of new opportunistic infections, malignancies or recurrence of infections e.g. oral candidiasis refractory to treatment or oesophageal candidiasis (T3 or T4). WHO Clinical staging for infants or children on ART is designated in codes from T1 to T4. summarises the management options for children on ART who are assessed and staged according to T stage. Clinical stages in this table refer to a new or recurrent condition in the WHO clinical staging (see table 5 on page 15) at the time of evaluating the infant or child on ART. WHO Clinical Stage on ART No new events or PGL (T 1) New stage 2 events (T 2)
New stage 3 events (T 3)
New stage 4 event (T 4)
Management options
§ Do not switch to a new regimen § Maintain scheduled follow up § Treat and manage staging event § Do not switch to new regimen § Assess and offer adherence support § Assess nutritional status and offer support § Schedule earlier visit for clinical review and consider CD4 § Treat and manage staging event and monitor response § Check if on treatment 24 weeks or more § Assess and offer adherence support § Assess nutritional status and offer support § Check CD4 - where available § Consider switching regimen § Institute more frequent follow up § Treat and manage staging event § Check if on treatment 24 weeks or more § Assess and offer adherence support § Assess nutritional status and offer support § Document CD4 - where available § Switch regimen
Table 15: Using the WHO Paediatric Clinical Staging System to guide decision-making regarding switching to second-line therapy for treatment failure
Notes: Differentiation of opportunistic infections from immune reconstitution syndrome is important. In considering changing treatment because of growth failure, it should be ensured that the child is not failing to grow due to lack of adequate nutrition, and that any intercurrent infections have been treated and resolved.
26
Pulmonary or lymph node TB, Clinical Stage 3 conditions, may not be an indication of treatment failure, and thus not require consideration of second-line therapy; response to tuberculosis therapy should be used to evaluate the need for switching of therapy. CD4 is best performed once the acute phase of the presenting illness is resolved. Immunological Failure The basis for recognising treatment failure is clinical assessment. CD4 results supplement the clinical criteria. Base your decision on 2 different CD4 measurements before deciding to switch to a second line regimen. Consider treatment failure if: CD4 drops to values at or below the age related CD4 threshold levels (See page 16) Or Confirmed return of CD4 % to baseline Or More than 50% decline in CD4 % Or No improvement in CD4 values despite at least 6 months of therapy NOTE: CD4 but not TLC is used for monitoring and defining treatment failure. TLC, while useful in the absence of CD4 measurement to guide when to initiate therapy, should not be used for the evaluation of response to ARV therapy as change in TLC is a poor predictor of treatment success. Virological Failure Not currently recommended for use to change to 2nd line by WHO.
E. Recommended 2nd Line Treatment In Cases Of Treatment Failure Abacavir + Didanosine + Ritonavir boosted Lopinavir (ABC + ddI + Kaletra) Patients on 2nd line treatment need very close monitoring. Laboratory Investigations Laboratory investigations should be done as per monitoring schedule for first line regimens. A Lipid profile (Total Glycerides and Cholesterol) at 4 weeks and 6 monthly thereafter needs to be added to monitor PI toxicity (Kaletra) includes lipid profile since the 2nd line regimen includes a PI. Step Up Adherence Poor adherence has been identified as one of the major causes of treatment failure. It is therefore very important to step up adherence in patients with poor adherence (adherence less than 80%), clinical indications of treatment failure or patients who start a 2nd line treatment.
27
Suggestions for stepping up adherence are listed below: Re-educate the primary and secondary caregivers about the importance of adherence. Re-emphasize the long-term benefits Evaluate the support structures in place. § Are they appropriate? § How can they be improved? § What alternatives are there? Consider the use of pillboxes and/or daily dosing diary. Insist on caregiver participation in a support group Consider doing a psychological profile. Re-assess the family situation (through social worker and therapeutic counselor). Home visits where possible (spot pill counts to be done at home).
3.8 TB in HIV infection
Also see National TB guidelines
The incidence of TB infection has increased with the HIV pandemic. TB is the most common opportunistic infection among HIV-infected people and accounts for a third of HIV related deaths. The progression of TB from infection to active disease is more rapid in younger children than older children and adults. Recognition of TB is more difficult in children
A. Signs And Symptoms Suggestive Of TB Signs and symptoms in infants and children are often non-specific: Chronic cough Weight loss/ wasting/failure to thrive (always check the RTHC) Persistent fever Failure to respond to conventional antibiotics
B. Diagnosis It is difficult to make a diagnosis of TB in infants and children because: Poor sputum production Gastric washings give poor yield CXR is non-specific Tuberculin skin test - may not respond due to poor immunity A high index of suspicion is necessary: Contact with a person with TB or with signs and symptoms of TB in the household Suggestive clinical signs Sputum for Z-N stain for AFBs and TB culture TST (Mantoux) § Use 5 IU of PPD intradermally § Response >5 mm induration is considered positive. § Negative Mantoux does not exclude TB
28
CXR § Non specific § Hilar adenopathy § Infiltrative changes
C. Scoring System For The Diagnosis Of TB In Children Various scoring systems have been used to assist in screening and strengthening the likelihood of TB in children. Unfortunately these scoring systems have not been validated. An example of the South African scoring system that can be used is given below. Feature General Weeks of illness Nutritional Status (weight for age) Family history of TB

Table 16: Scoring system for the diagnosis of TB in children (a score of 7 or more indicates a high likelihood of TB). Source: South African National TB Control Program Practical Guidelines 2004.
D. Treatment Of TB HIV infected children, diagnosed with TB, should have TB treated first where possible before starting ART. Use the recommended national standard treatment guidelines using a combination of the following drugs: Rifampicin (R) INH (H) Pyrazinamide (Z) Ethambutol (E) –only for re treatment cases
Standard TB regimens for children: New Pulmonary TB: 2RHZ/4RH Retreatment cases 3RHZE/5RHE
29
Note: Ethambutol is not routinely used in children below 8 years except in re-treatment cases. The dosage of ethambutol should be calculated strictly per Kg body weight in children. Close monitoring for loss of vision is necessary.
E. ART in TB /HIV Co- Infected Children The management of TB in HIV infected children, and the treatment of severe HIV infection with antiretroviral drugs is complicated by the potential for multiple drug interactions. Rifampicin interacts with the NNRTI (especially with nevirapine) and PI classes. Use of PI or Nevirapine together with rifampicin may result in sub-therapeutic antiretroviral drug levels and potentially in HIV treatment failure. The choice of ART regimen in TB/HIV co-infected children is also complicated by the limited options for paediatric drug formulations and/or dosing information (particularly for children less than 3 years of age) for antiretroviral drugs. This further limits ART options for co-infected children. When to start This depends on the child's clinical condition and immunological stage: TB treatment takes priority HIV Clinical stage 3 and 4 or severe immunological suppression (based on CD4 â&#x20AC;&#x201C; see on page ): Consider ART after stabilizing the patient for at least 2-8 weeks on TB treatment. The decision on whether to commence after 2 weeks of anti-TB treatment or to finish the intensive phased is based on clinical assessment of individual patients. Patients with Clinical Stage 3 (Lymph Node TB or pulmonary TB) with good response to anti TB Rx could delay ART initiation and should be re-evaluated after TB treatment. In stable patients complete TB treatment before commencing on ART. Advantages of delaying ART in patients on TB treatment. Reduces pill burden Improves adherence Better monitoring and differentiation of any adverse effects Recommended start regimen for children on TB treatment If patients needs to take TB treatment and ARTs together, then the recommended regimens are AZT, 3TC and Ritonavir boosted Kaletra in children 3 years or younger and AZT, 3TC and EFZ in children older than 3 years. The Ritonavir/Lopinavir ratio in Kaletra is 1:4. This needs to be boosted to a 1:1 ratio; therefore, Ritonavir needs to be added to the Kaletra tablets.
Child < 3 years: AZT + 3TC + Ritonavir boosted Kaletra Child > 3 years: AZT + 3TC + EFZ IRIS should be considered especially if CD4 is very low at commencement of ART Decisions on 2nd line ART regimens in TB should be referred to a specialist.
30
Evaluate the possibility of delaying ART initiation depending on the clinical status and CD4, and on clinical and immunological response to TB therapy. Children already on ART who need to start TB treatment These children should continue with ART but a review of their ART regimen is needed. Replace nevirapine with EFV in children >3yrs.
F. TB Prophylaxis Routine INH prophylaxis in HIV infected children is not recommended. INH prophylaxis against TB should be given to all children less than 5 years old who are exposed to TB in their household as per national TB guidelines (regardless of HIV status). Active disease must be ruled out first. INH for TB prophylaxis is given as a single oral daily dose of 10 mg/kg for 6 months.
Cotrimoxazole prophylaxis should always be continued in infants and children on TB treatment
31
Chapter 4: Nutrition in HIV Nutrition plays a crucial role in child health and in HIV/AIDS in particular. The interaction between nutrition, infection and immunity is well recognized.
4.1. Causes of poor nutritional status in HIV infected children Poor nutrient (food) intake Reduced appetite Oral sores Limited food availability Encephalopathy with feeding problems Malabsorption Nausea and vomiting Diarrhoea, recurrent and persistent Increased nutritional requirements Chronic infections e.g TB Fever, increased catabolism Malignancies Depression Loss parents (Orphans) Side - effects of drugs
4.2. Assessment of the nutritional status Assess nutritional status, weigh child and offer nutrition counselling at EVERY visit Record the weight on the Road to Health Chart Always measure: Weight Height Head circumference (children<2yrs) Check the weight for height on growth charts. Weight for height >90% -- nutrition is good Weight for height <70% -- severe wasting Check the weight for age if height not available Weight for age >80% -- nutrition is good Weight for age <60% -- marasmus Check for Bilateral pitting pedal oedema --- kwashiorkor Check for signs of visible severe wasting (see IMCI guidelines)
32
Check the child's RTHC. Decide whether there is good weight gain, or growth faltering (slower than expected rate of growth or drop in weight). Counsel the caregiver accordingly. If child is on ART, assess with other findings whether this is an indicator of poor response to ART.
4.3 Nutritional rehabilitation. Guidelines for management of severe malnutrition should be used. Precise information of caloric needs for HIV-infected children is not available. Severely malnourished children need admission and intensive management. HIV-infected children have increased energy needs. Refer to IMCI feeding recommendations for the dietary advice. General advice General Hygiene on handling food. Always wash hands with soap and water Use safe water that is boiled or filtered Small frequent feeds might be better tolerated. Increase gradually.
4.4 Infant feeding Refer to infant feeding guidelines. Breast-feeding increases the risk of HIV transmission to baby by up to 20%. The risk of transmission through breast milk increases with the duration of breastfeeding. Maternal factors like recent infection, advanced maternal disease, low CD4 count, high viral load and mastitis increase the risk of infection. Mothers should be counselled on infant feeding choices. Correct and adequate information should be given to enable the mother to make an informed choice of the feeding option. Feeding counselling should start during ANC care. Support the mother appropriately depending on the option she will have chosen.
A. The Different Feeding Options Considering the risk of HIV through breastfeeding and the risk of morbidity and mortality from other causes UN (WHO/UNICEF and others) recommends the following for HIV infected mothers: - â&#x20AC;&#x153;Exclusive breastfeeding is recommended for HIV-infected women for the first 6 months of life unless replacement feeding is acceptable, feasible, affordable, sustainable and safe for them and their infants before that time. -
When replacement feeding is acceptable, feasible, affordable, sustainable and safe, avoidance of all breastfeeding by HIV-infected women is recommended.
33
-
At six months, if replacement feeding is still not acceptable, feasible, affordable, sustainable and safe, continuation of breastfeeding with additional complementary foods is recommended, while the mother and baby continue to be regularly assessed. All breastfeeding should stop once a nutritionally adequate and safe diet without breast milk can be provided.”
Adequate counselling is therefore essential to be able to equip the mother to make an informed choice on the appropriate feeding option and to support her on the choice she will have made. Support the mother who has chosen to breastfeed. Counsel the mother on the importance of exclusive breastfeeding for up to 6 months. Breastfeeding should be discontinued as soon as is feasible. As part of supporting this mother AFASS of replacement feeding should be continuously assessed. Encourage growth and development monitoring monthly in Under 5 clinic. Support the mother who has chosen not to breastfeed. Counsel mother on replacement feeding. Discuss all the AFASS criteria. Assist her in choosing the appropriate feeding option for her baby. Infant feeding options are: § Formula feeding § Home-modified animal milk (fresh or processed animal milk that is modified by adding water, sugar and micronutrient) § Expressing and heat-treating breast milk to kill HIV virus.
Mixed feeding increase the risk of HIV transmission and should be discouraged

Chapter 5: Care and Treatment for Adolescents The World Health Organization defines “adolescents” as individuals aged 10 – 19 years and “young people” as those aged 10 – 24 years, but the definitions are not quite that simple. Adolescents are a special population. Adolescents are not “older children” nor are they “little adults”. In fact, adolescence is a period of transitioning from childhood to adulthood, with many physical, mental, and emotional changes. There are three stages of adolescence: 1. Early adolescence (age 10-13 years), where there are many questions about the changes that are occurring. There is emphasis on relationships with peers, or a shift in attachments. Thinking is very concrete, and they tend to act impulsively 2. Middle adolescence (age 14-16 years), where pubertal development is nearing completion. Abstract reasoning is developing, but there is still some immaturity in the ability to deal with the outside world. There is increased concern with self-image. 3. Late adolescence (age 17-21 years), where body image and gender role are defined. Individual relationships become more important than peer group. Cognitive development is usually complete at this time, and thus better awareness of the consequences of actions. There is overall comfort with self and with others.
5.1. Risk Factors for HIV Infection These include developmental stage, biologic and physical characteristics, individual attributes, and their environment. Adolescents often have issues such as denial, adherence, sexuality, peer pressure, school issues, and other responsibilities that may affect behaviour. Low self esteem has been shown to increase the probability of risk-taking behaviour that includes sexual experimentation or substance abuse. Lack of education about proper conduct and practices also puts many adolescents at risk of acquiring HIV. Many believe that they are invincible and that “it won't happen to me”. While boys tend to initiate sex earlier than girls, and adolescents growing up in rural areas are more likely to be sexually active than those growing up in urban areas, girls are more vulnerable. Biologically, the immature female cervix is more vulnerable to HIV infection than in older women. Gender imbalance often makes many young women feel powerless to insist on safer sex practices like abstinence or condom use. Girls are more likely to marry and to become pregnant, increasing the risk of HIV infection. In Swaziland, this time can be very difficult for most adolescents. For example, orphaned adolescents are often forced to become leaders of the household or are often thrust into adult responsibilities. Attempts at survival can lead to sex work, homelessness, and exploitation. Adolescence is a critical turning point in the lives of children, so much that proper guidance now in diminishing risky behaviours can lead to more positive outcomes later. The establishment of adolescent and youth-friendly services (sexual, reproductive, counselling and testing) is important in improving universal access to adolescents.
36
5.2. Counselling and Disclosure Specialists agree that physicians should fully disclose to teenage patients and parents should answer children's questions truthfully and honestly. The adolescent should also be counselled about disclosing his or her status to others, e.g. friends and family, about the costs and benefits of disclosure, and that there is no compulsory disclosure. However, the patient must be counselled on responsibility to sexual partners. Patients are less likely to disclose if they engage in casual sexual encounters. The counsellor should discuss issues of legal and moral obligation to the partner, but even with good counselling this process can be very difficult. In Swaziland, the age of informed consent is 16 years, where the patient no longer needs permission from guardian. They are fully expected to make decisions for themselves. However, there are some adolescents as young as 11 years of age who are mothers and are expected to care for others. As such, adolescents of all ages must be empowered to take care of themselves, to be responsible for their own health care, and to be responsible participants in society and community as well. They must be allowed to ascertain their own serostatus. They must be involved in discussions about medication adherence and the importance of regular visits to the health facility. However, they should also be encouraged to disclose to other family members to improve their social support.
5.3. Medical Management of Adolescents HIV is known to cause delays in development and sexual maturity. This is why many adolescents appear physically much younger than their chronologic age. This impacts the dosage of prescribed medications, especially antiretroviral therapy. If the child is in Tanner Stage I, II or III (See appendix 5 on page 75), they should still be dosed on the paediatric mg/kg (per weight) or on the body surface area. At Tanner Stages IV and IV, they are treated with adult dosing if the weight > 60 kg. In the case of antiretroviral therapy, again remember that not all adolescents will be mature enough to have the knowledge and understanding of the life-time commitment of HIV therapy, so it is best to individualize counselling and services to the individual patient.
5.4. Adolescent Needs in Swaziland Adolescent HIV programs in Swaziland need to acknowledge the rights of each client: Information, especially reproductive health services that provide information, education and counselling on sexual and reproductive health issues, STI, HIV, contraception, pregnancy testing and counselling, antenatal and postnatal care. Access to care regardless of sex, sexual orientation, or any other reasons. Choice Safety Privacy Confidentiality Dignity to be treated with courtesy and attentiveness, not merely as a statistic Comfort while receiving services in an adolescent friendly environment. Continuity of care for as long as the care is needed Opinions that should be expressed
37
HIV counselling and testing services should cater to adolescents who are sexually active, pregnant, or who have children, and allow them to consent for HIV testing. Support services for adolescents in Swaziland should be multidisciplinary and comprehensive. Health care providers should be equipped to supply the adolescents with contact information for relevant organizations providing support services that are appropriate for their needs.

Chapter 6: Non-occupational post-exposure prophylaxis 6.1. Rationale for PEP for non-occupational exposure to HIV When exposure occurs in the occupational setting to HCWs, the HIV status of the source person can usually be determined. This is rarely the case following non-occupational exposure. People who are exposed to blood (e.g. through violence, needle sticks, dirty knives or blades) or victims of sexual abuse are included in the category of non-occupational exposure to HIV. Unfortunately sexual abuse is not uncommon in Swaziland. During the 6 month period from September 2004 to March 2005, out of over 360 reported cases of sexual abuse in Swaziland, over 180 occurred in young people under the age of 20 years. In a country with a high prevalence rate of HIV among the most sexually active group and a high occurrence of rape cases, health workers should offer post-exposure prophylaxis (PEP) to victims of rape. Rape causes genital tract trauma that increases the risk of HIV transmission to the victim.
6.2. Management of non-occupational exposure to HIV Victims should be taken immediately to the nearest referral PEP centre even before questioning by the police. Qualified medical staff should examine the victim carefully, document her/his clinical condition, and establish evidence for violence. The medical personnel should perform a thorough examination of the genital area. Samples should be acquired for laboratory analysis. If the victim is less than 18 years of age, every attempt should be made to encourage the patient to involve the caretaker or caretakers. The examination and laboratory tests should be offered routinely; if an adult victim refuses to be tested for HIV, no PEP will be offered. Antiretroviral therapy should be offered according to the algorithm in Figure 6: HIV Positive Source*

* If there is a substantial risk of HIV transmission, a 3-drug regimen may be considered by adding efavirenz, lopinavir/ritonavir, nelfinavir, or indinavir ** Clinical judgment must be taken into account. If there is a high risk of HIV transmission, and if the benefits of using 2 drug ARV outweigh the costs in this scenario, it is within the health worker's discretion to provide PEP.

41
6.3. Counselling and Testing Pre- and post-test HIV test counselling and appropriate psychosocial support for victims of abuse should be offered to the victim and the parents/guardians. Confidentiality must be assured and an anonymous form should be filled in. Advise the victim to take STI prophylaxis. Perform a pregnancy test in females. Counselling should include the risk of transmission and acknowledgement of the options open to the victim and her/his family. Assistance should be made in reporting the assault to the proper authorities.

Appendix 3 Serious Acute and Chronic Toxicities due to ARV Drugs that may require therapy modification Source: Antiretroviral therapy of HIV infection in infants and children in resource-limited settings: towards universal access. Recommendations for a public health approach. 2006. World Health Organisation Remark: Alternative explanations for toxicity must be excluded before concluding that it is secondary to the ARV drug. This table describes management of the ART regimen but does not indicate detailed clinical toxicity management. Possible clinical manifestations (Most common ARV drug or drugs associated with the toxicity)
Possible laboratory abnormalitiesa
Implications for antiretroviral drug treatment
Accute serious adverse reactions Acute symptomatic hepatitis (NNRTI class, particulary NVP, more rarely EFV; NRTIs or PI class) § Jaundice § Liver enlargement § gastrointestinal symptoms § Fatigue, anorexia § My have hypersensitivity component (rash, fever, systemic symptoms), usually occur within 6-8 weeks. § May have accompanying lactic acidosis (see below) if seconadry to NRTI drug.
§ Elevated transaminases § Elevated bilirubin.
§ Discontinue all ARV until
symtoms resolve § If possible, monitor
transaminases, bilirubin § If receiving NVP, it should NOT
be readministered to the patient in future. § Once symptoms resolve, either: - restart ART with change to alternative ARV (if on NVP regimen, this is required): or - restart current ART regimen with close observation; if symptoms recur, substitute alternative ARV b
Acute pancreatitis (NRTI class, particularly d4T, ddl; more rarely 3TC) § Severe nausea and vomiting § Severe abdominal pain § May have accompanying lactic
acidosis (see below)
§ Elevated transaminases § Elevated eosinophil count
72
§ Discontinue all ARVs uuntil symptoms resolve § If possible, monitor serum pancreatic, lipase § Once symptoms resolve, restart ART with substitution of an alternative NRTI, preferably one without pancreatic toxicityb
Possible clinical manifestations (Most common ARV drug or drugs associated with the toxicity)
Possible laboratory abnormalitiesa
Implications for antiretroviral drug treatment
Hypersensitivity reaction (ABC or NVP) § ABC: Combination of acute § Elevated onset of both respiratory and transaminases gastrointestinal symptoms after § Elevated eosinophil restarting ABC, including fever, count fatigue myalgia, nausea, vomiting, diarrhoea, abdominal pain, pharyngitis, cough, dyspnoea; rash (usually mild) may or may not occur; progressive worsening of symptoms soon after receiving ABC dose, usually occurs within 6-8 weeks § NVP: Systemic symptoms of fever, myalgia, arthralgia, hepatitis, with or without rash. Possible clinical manifestations (Most common ARV drug or drugs associated with the toxicity)
Possible laboratory abnormalitiesa
§ Immediately discontinue all ARVs until symptoms resolve § NVP or ABC should NOT be readministered to the patient in future. § Once symptoms resolve, restart ART with substitution of an alterantive ARV for ABC or NVPb
Implications for antiretroviral drug treatment
Lactic acidosis (NRTI class, particularly d4T) § Generalized fatigue and weakness § Gastrointentinal features (nausea,
vomiting, diarrhoea, abdominal pain, hepatomegaly, anorexia, poor weight gain and/or unexplained weight loss) § May have hepatitis or pancreatitis (see above) § Respiratory features (tachypnoea and dyspnoea) § Neurological symptoms (including motor weakness)
§ Increased anion gap § Lactic acidosis § Elevated
aminotransferase § Elevated CPK § Elevated LDH
73
§ Discontinue all ARVs until
symptoms resolve § Symptoms associated with lactic
acidosis may continue or worsen despite discontinuation of ART § Once symptoms resolve, restart ART with substitution of an alternative NRTI with lower mitochondrial toxicity risk (e.g. ABC or AZT) b
Possible clinical manifestations (Most common ARV drug or drugs associated with the toxicity)
Possible laboratory abnormalitiesa
Implications for antiretroviral drug treatment
Severe rash/Stevens-Johnson syndrome (NNRTI class, particularly NVP, less common EFV) § Rash usually occurs during first 6-8
§ Elevated
weeks of treatment § Mild to moderate rash: erythematours, maculopapular, confluent, most often on the body and arms, with no systemic symptoms § Severe rash: extensive rash with moist desquamation, angiooedema, or serum sickness-like reaction; or rash with constitutional findings such as fever, oral lesions, blistering, facial oedema, conjunctivitis. § Life-threatining Stevens-Johnson syndrome or toxic epidermal necrolysis
aminotransferases
§ If mild or moderate rash, ART can
continue without interruption staying at induction dose until rash settles but with close observation, and only increase to maintenance dose once tolerated § For severe or life-threatening rash, discontinue all ARVs until symptoms resolve § NVP should NOT be readministered to the patient in the future. § Once symptoms resolve, restart ART with substitution of an alternative ARV for NVP (note: most experts would not change to another NNRTI drug if patient had severe or life-threatening StevensJohnson syndrome with NVP) b
Severe life-threatening anaemia (AZT) § Severe pallor, tachycardia § Significant fatigue § Congestive heart failure
§ Low haemoglobin
§ If refractroy to symtomatic
treatment (e.g. tranfusion) discontinue AZT only and substitute an alternative NRTI b
Severe neotropenia (AZT) § Sepasis/infection
§ Low neutrophil
§ If refactory to symptomatic
treatment (e.g. transfusion), discontinue AZT only and substitute an alternative NRTI b

Appendix 4 Side effects (Adverse Events) of Antiretroviral Agents Mild side effects such as headache, fatigue, gastrointestinal upsets and diarrhoea occur fairly frequently, but the serious side effects occur rarely. Mild side effects usually occur early in treatment and often wear off and should be treated symptomatically. Side effects of antiretroviral drugs are summarized with the specific drug information later in this booklet. Grading of Adverse Events Grade 1 Mild Transient or mild discomfort; no limitation in activity; no medical intervention/therapy required Grade 2 Moderate Mild to moderate limitation in activity-some assistance may be needed; no or minimal medical intervention/therapy required. Grade 3 Severe Marked limitation in activity; assistance usually required; medical intervention/therapy required; hospitalization possible. Grade 4 Life-threatening Extreme limitation in activity, significant assistance required; significant medical intervention/therapy required; hospitalization or hospice care probable. Action on Grading of Adverse Events Grades 1 and 2: · Child remains on therapy. · Repeat the test. · Reassess clinically within 2 weeks Grade 3: · Test/exam should be repeated within 1 week. · If still Grade 3, stop all antiretroviral drugs and seek expert medical advice. Grade 4: · Stop all drugs immediately and seek specialist advice. · If the patient restarts therapy after the event has resolved, and the same grade 4 event recurs, appropriate changes or withdrawal of antiretroviral therapy may need to be made. Decisions should be made on an individual basis, and discussed with experts as required.
