Helping HIV Infected Patients in South Africa Adhere to Drug Regimens
DOT-HAART for HIV-Infected South African Adults
Three or more anti-HIV drugs are taken in combination as part of a treatment regimen. These drug regimens must be closely followed in order to be successful. Having a support person watch a patient take his or her anti-HIV drugs each day may help a patient follow his or her regimen. This study will see if patient-chosen treatment supporters help patients take HIV medicines correctly and improve their health.
Study hypothesis: The mean change in CD4 count at 12 and 24 months will be significantly higher in the directly observed therapy-highly active antiretroviral therapy (DOT-HAART) arm as compared to the self-administered arm.

Descripción detallada
South Africa has one of the worst and fastest growing HIV epidemics in the world. Highly active antiretroviral therapy (HAART) has been shown both at the individual and public health levels to reduce morbidity, mortality, and vertical and possibly horizontal HIV transmission. However, expenses, feasibility, long-term adherence, and effective delivery of HAART remain formidable barriers, particularly in developing nations. Recently, international initiatives have provided hope for widespread use of HAART at affordable cost in sub-Saharan Africa. Simplified, once-daily HAART regimens with directly observed therapy (DOT) may help to achieve high levels of treatment adherence, a key component for long-term viral suppression and treatment success. Peer advocates have been used to improve adherence with medical therapies in a variety of settings. This study will evaluate the effectiveness and feasibility of DOT using patient-nominated peer supervisors to improve adherence to HAART in HIV infected adults in South Africa.
Participants will be randomly assigned to either Peer-DOT-HAART or self-administration of a once-daily combination of the Western Cape Province ART program medications for 24 months. Study measures will include CD4 cell count and HIV viral load, adherence questionnaires, genotypic HAART resistance testing, and incidence of new or recurrent opportunistic infections.
