Background: Our objective was to study feasibility, effectiveness, adherence, toxicity, and viral resistance in an African government HAART initiative.
Methods: A prospective observational cohort study was started in Dakar in August 1998. Initial treatment consisted of 2 NRTIs and 1 PI.
The primary endpoint for efficacy was a reduction in plasma HIV-1 RNA to below the detection limit. Change in the CD4 cell count were analyzed using Wilcoxon's test. Data were analyzed on an intention-to-treat and "tritherapy received" basis. Changes in adherence with time was assessed using a logistic repression model for repeated data. Genotypic viral resistance was also studied.
Results: 58 treatment-naïve patients, most infected by HIV-1 strain CRF02-AG, were enrolled. The mean CD4 cell count was 108/mm3 and the mean viral load was 106 400 copies/mL. Adherence was good in 87.9% of patients. HIV-1 RNA was undetectable in more than 80% of patients one month after treatment outset, and in 57.7% of patients at month 18. CD4 cell counts rose by a mean of 82, 151 and 180/mm3 at months 6, 12, and 18, respectively. Seven clinical AIDS-defining events occurred during follow-up. A total of 46 adverse effects were reported, and most were mild or moderate. 2 cases of drug resistance occurred. The cumulative probability of remaining alive or free of new AIDS-defining events was 94.8% at 6 months and 82.3% at 18 months.
Conclusions: This study shows that HAART is feasible and well tolerated in African patients. Clinical and biological results were comparable to those seen in Western cohorts, despite differences in the HIV-1 subtype distribution and an advanced disease stage when the treatment was initiated. Contrary to other recent reports in Africa, viral resistance rarely emerged.
