Superiority of directly administered antiretroviral therapy over self-administered therapy among HIV-infected drug users: a prospective, randomized, controlled trial.

ABSTRACT: Directly administered antiretroviral therapy (DAART) is one approach to improve treatment adherence among human immunodeficiency virus (HIV)-infected drug users.In this randomized, controlled trial (ClinicalTrials.gov identifier, NCT00367172), the biological outcomes of a 6-month community intervention of DAART were compared with those of self-administered therapy among HIV-infected drug users. Patients randomized to receive DAART received supervised therapy 5 days per week from workers in a mobile health care van. The primary outcome, using an intention-to-treat approach, was the proportion of patients achieving either a reduction in HIV-1 RNA level of > or = 1.0 log10 copies/mL or an HIV-1 RNA level < or = 400 copies/mL at 6 months. Secondary outcomes included the mean change from baseline in HIV-1 RNA level and CD4+ T lymphocyte count.Of the 141 patients who met the entry criteria, 88 were randomized to receive DAART, and 53 were randomized to receive self-administered therapy; 74 (84%) of 88 of the patients randomized to receive DAART accepted the intervention. Of the 74 patients who initiated DAART, 51 (69%) completed the full 6-month intervention. At the end of 6 months, a significantly greater proportion of the DAART group achieved the primary outcome (70.5% vs. 54.7; P=.02). Additionally, compared with patients receiving self-administered therapy, patients receiving DAART demonstrated a significantly greater mean reduction in HIV-1 RNA level (-1.16 log10 copies/mL vs. -0.29 log10 copies/mL; P=.03) and mean increase in CD4+ T lymphocyte count (+58.8 cells/microL vs. -24.0 cells/microL; P=.002).This randomized, controlled trial was, to our knowledge, the first to demonstrate the effectiveness of DAART at improving 6-month virologic outcomes among drug users. These results suggest that DAART should be more widely available in HIV treatment programs that target drug users who have poor adherence to treatment.

Project description:BackgroundDepression is highly prevalent among HIV-infected injection drug users (IDUs) and has been associated with poor adherence to antiretroviral therapy and increased morbidity and mortality. Factors associated with changes in depressive symptoms among this group receiving antiretroviral treatment that have not been extensively evaluated.MethodsThis post-hoc analysis of prospective clinical trial analyzes the factors associated with changes in depressive symptomatology using the Center for Epidemiologic Studies of Depression Scale (CES-D) among HIV-infected IDUs enrolled in a prospective, six months randomized controlled trial of directly administered antiretroviral therapy (DAART) versus self-administered therapy.ResultsOf the 127 evaluable IDUs enrolled in the study, 89 subjects (70%) had complete six-month follow-up data. Of these, 58 (63%) met baseline criteria for severe or major depressive disorder (MDD) using the CES-D. CES-D scores improved significantly from baseline to six months overall for the 89 subjects (p=0.01) and for the 58 who had MDD with six-month data (p=0.001). Using multiple regression, an improvement in CES-D score was independently associated with: (1) increase in CD4 count; (2) increase in adherence; (3) non-Caucasian race; and (4) older age. Worsening in CES-D score was associated with: (1) increase in HIV-1 RNA levels; (2) homelessness; (3) poor self-efficacy; (4) active drug use; and (5) male gender. Factors not correlated with changes in CES-D were receipt of DAART, engagement in drug treatment, use of antidepressant medication, and employment. Using generalized estimating equation modeling, factors that remained positively associated with improvements in CES-D score were absence of drug use at six months, having housing, higher self-efficacy, increase in CD4 count and increases in adherence.ConclusionImprovements in depressive symptoms could occur with improvement of alterable factors that are associated with strengthening adherence such as linkages to case management, mental health and substance abuse treatment services as well as through enhancement of social stabilization factors through social support and supportive housing.
