Trial Title: Efficacy Study of Different Laboratory Management Strategies and Drug Regimens in HIV-infected Children in Africa

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: FACTORIAL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: NONE
- Phase: PHASE4
- Number of Arms: 9.0

Eligibility Criteria:
For initial randomisation to CDM vs LCM, and to ART induction strategy:~Inclusion Criteria:~1. Children should have an adult carer in the household who is either:~   * participating in the DART trial OR~  * being treated with ART OR~  * HIV positive but not yet needing treatment but with access to a treatment programme when ART is required OR~  * HIV negative. Children of DART participants should have first priority on any available remaining slots to enter ARROW.~2. Parents or guardians, and children where appropriate according to age and knowledge of HIV status, must be willing and able to give informed consent for randomisation to CDM or LCM and to first-line ART strategy.~3. Participants must have a confirmed documented diagnosis of HIV-1 infection:~   1. For children aged under 18 months: two separate peripheral blood specimens from different days, both results being positive with HIV-DNA polymerase chain reaction (PCR).~  2. For children aged 18 months or over: antibody positive serology by ELISA test (confirmed by licensed second ELISA or Western Blot) or WHO approved rapid test (performed in series) both on the same sample. Any child previously tested at another clinic should have a repeat test at an ARROW screening laboratory to confirm their status.~4. Age 3 months to 17 years (13-17 years to be capped at 10%)~5. ART naïve (except for exposure to perinatal ART for the prevention of mother-to-child HIV transmission).~6. Meeting criteria for requiring ART according to WHO stage and CD4 percent or count:~   * WHO paediatric clinical stage IV disease: treat regardless of CD4 percent or count~  * WHO paediatric clinical stage III disease:~     * \<12 months: treat all~    * \>12 months: treat all children irrespective of the CD4 percent or count; however, in children aged \> 12 months with tuberculosis, lymphocytic interstitial pneumonia (LIP), oral hairy leukoplakia (OHP) or thrombocytopenia (low platelet count treat) be guided by CD4 cell assays (see below).~  * WHO paediatric clinical stage II or I disease: treat guided by CD4 percent or count~     * CD4%\<25% for infants \<12 months;~    * CD4%\<20% for children 1-\<3 years;~    * CD4% \<15% for children 3-\<5years;~    * CD4% \<15% for children \> 5years (consideration should also be taken of the CD4 count. A CD4 count \<200 cells/mm3 can be used to guide starting ART and CD4 should generally be \<350 cells/mm3.)~Exclusion Criteria:~1. Cannot, or unlikely to attend regularly (e.g. usual residence too far from study centre)~2. Likelihood of poor adherence~3. Presence of acute infection (e.g. malaria, helminthiasis, acute hepatitis, acute pneumonia, septicaemia, meningitis). Children may be admitted after recovery of an acute infection. Children with chronic lung disease, including recurrent respiratory infections, are eligible. Children with tuberculosis (TB) will not be enrolled while on the intensive phase of anti-tuberculosis therapy, but should be re-evaluated after the intensive phase and a decision made then about starting ART (see 4 below)~4. In receipt of medication contraindicated by ART~   * children under three years of age receiving anti-tuberculosis therapy should not be enrolled (as they will have to receive nevirapine).~  * on chemotherapy for malignancy~5. Laboratory abnormalities which are a contra-indication for the child to start ART (haemoglobin \<8.5g/dL; neutrophils \<0.50x109/L; aspartate transaminase (AST) or alanine transaminase (ALT) \>5 x the upper limit of normal (ULN); grade 3 renal dysfunction - creatinine \>1.9 x ULN).~   N.B. causes of anaemia, such as concurrent bacterial infection, malaria, helminthiasis and/or malnutrition should be investigated, and treatment for anaemia and its causes commenced prior to re-screening for eligibility.~6. Being pregnant or breast-feeding an infant~7. Perinatal exposure to nevirapine (either through prevention of mother-to-child transmission (pMTCT) or breastfeeding) for children aged 3 - 6 months only~Eligibility criteria for the secondary randomisation to once vs twice daily lamivudine+abacavir Inclusion criteria~1. Participating in ARROW~2. On ART for at least 36 weeks~3. Currently taking lamivudine+abacavir twice daily as part of their ART regimen and expected to stay on these two drugs for at least the next 12 weeks~4. Parents or guardians, and children where appropriate according to age and knowledge of HIV status, must be willing and able to give informed consent for randomisation to once or twice daily lamivudine+abacavir~   Exclusion criteria~5. Likely to switch to second-line therapy in the next 12 weeks~Eligibility criteria for the secondary randomisation to stop or continue cotrimoxazole prophylaxis randomisation Inclusion criteria~1. Participating in ARROW~2. Aged at least 3 years~3. Initiated ART at least 96 weeks previously, and received at least 96 weeks of ART allowing for any interruptions in ART~4. Currently prescribed daily cotrimoxazole as primary prophylaxis~5. Parents or guardians, and children where appropriate according to age and knowledge of HIV status, must be willing and able to give informed consent for randomisation to stop or continue daily cotrimoxazole prophylaxis~6. If living in a malaria endemic area, has an insecticide treated bednet and prepared to use this for the child.~   Exclusion criteria~7. Previous diagnosis of Pneumocystis jiroveci pneumonia (cotrimoxazole is secondary prophylaxis and should not be discontinued)
