Study design: This is a randomized trial comparing adherence to antiretroviral drugs and clinical outcomes between 50 HIV-1 infected Kenyan children randomized to a simple medication diary plus standard counseling with a similar group of children randomized to counseling alone.
Parents or caregivers of HIV-1 infected children discharged from the Kenyatta National Hospital (KNH) children's wards or seen in pediatric outpatient clinics will be invited to participate in the study by nurse counselors. Informed written consent will be obtained from those who meet eligibility criteria and agree to participate. The consenting process will be done by the principal investigator in a confidential area. A baseline questionnaire will be administered to obtain socio-demographic information and previous medical history of the parents/caregiver and child. All those enrolled will undergo three sessions of counseling conducted by a trained nurse counselor regarding antiretroviral therapy over a two-week period.
After successful completion of the counseling process, 8 mls of blood will be drawn from each child for liver function tests, urea, blood count including hemoglobin, CD4 cell count and HIV-1 viral load.
After receiving results of the laboratory tests, children will be randomized to two groups. Those in the first group will be given a medication diary in which caregivers will record the child's daily intake of antiretroviral drugs. Those in the second group will be followed up without a diary. Children in both groups will be started on three antiretroviral drugs: zidovudine, nevirapine, and lamivudine. Caregivers will be requested to bring to the next clinic appointments drug containers for the past month's prescriptions. Those in the intervention arm will be requested to carry the medication diaries to all appointments.
Follow-up: Clinic appointments will be planned for 2 weeks after initiating antiretroviral therapy and at monthly intervals thereafter. At each visit, adherence will be monitored using self report using the pediatric adherence questionnaire. Pill counts will be performed at 3-monthly intervals. A study nurse will review the medication diary with each parent/caregiver in the intervention study arm, and address any issues raised about the diary use.
At 3,6, and 9 months after initiation of antiretroviral therapy, 8 mls of blood will be drawn from each child for liver function tests, urea, blood count including hemoglobin, CD4 cell count and HIV-1 viral load, and antiretroviral drug resistance.
In-depth interviews will be conducted with caregivers to cover a broad range of experiences.
The second two aims of this study are summarized below:
Aim 2): Define correlates of adherence measured by self report to specific components of a pediatric HAART regimen in HIV-1 infected children initiating therapy in Nairobi, Kenya.
Aim 3) Identify behavioral and social problems experienced by caregivers in relation to paediatric HAART adherence and define mechanisms to improve adherence.
