Directly Observed Antiretroviral Therapy Among Active Drug Users
- Conditions
- HIV/AIDSSubstance Abuse
- Registration Number
- NCT00367172
- Lead Sponsor
- Yale University
- Brief Summary
The goal of this randomized, controlled trial is to compare the effectiveness of a community-based program of providing supervised antiretroviral therapy to HIV-positive drug users, compared to having the patients take the medicines on their own.
- Detailed Description
Highly active antiretroviral therapy (HAART) has dramatically reduced morbidity and mortality from HIV disease, but these benefits have not been conferred equally among all patient populations. Injection drug users (IDUs) have shown particularly less favorable outcomes, with HIV progression remaining at high levels, and IDU remains a significant risk behavior for the spread of HIV worldwide, with explosive epidemics in Eastern Europe, Russia, and Southeast Asia. It is therefore essential to develop and test strategies of HIV treatment that optimize outcomes for this population, in order to reduce morbidity and mortality and to curb secondary transmission.
Directly observed therapy (DOT) for tuberculosis has resulted in impressive improvements in adherence and clinical response and marked reductions in the development of resistance. The time-limited treatment of tuberculosis, the inherently different transmission patterns of tuberculosis and HIV, and the complexity of antiretroviral therapy have raised concerns about translating the DOT model to HIV. Successful, but non-comparative demonstration programs of directly administered antiretroviral therapy (DAART) have been implemented in methadone maintenance programs, community-based settings, skilled nursing facilities, and in prisons. None of these, however, have targeted active drug users or used a prospective, randomized controlled trial (RCT) design to rigorously determine the efficacy of DAART as an intervention to improve HIV outcomes among active drug users. One RCT of DAART recently failed to demonstrate an impact on virological outcomes among low-income HIV+ patients, but these results are unlikely to be applicable to IDUs or other populations with demonstrated problematic adherence.
We therefore conducted the first randomized controlled trial to address this question, consisting of six months of DAART versus self-administered therapy (SAT) among active drug users in a community setting. The objective was to determine the potential efficacy of a six-month DAART program on HIV infection, using surrogate markers of HIV- RNA levels and CD4+ T lymphocyte counts.
