ABSTRACT
OBJECTIVE:
To compare virological and immunological responsiveness of efavirenz (EFV)-based highly active anti retroviral therapy (HAART) between patients with baseline CD4 < 100 and CD4 > or = 100 cells/mm3. MATERIAL ANDMETHOD:
A prospective cohort study in antiretroviral-naive HIV-infected patients was conducted between February and April 2002. Donated HAART regimen, consisting of stavudine, didanosine, and EFV was initiated. The primary outcome was time to undetectable HIV RNA, < 50 copies/mL. Patients were followed up every 12 weeks until 48 weeks (the end of the study).RESULTS:
Forty-six patients were included, 21 patients for CD4 < 100 cells/mm3 and 25 patients for CD4 > or = 100 cells/mm3. Median CD4 cell counts of these corresponding groups were 26.5 and 177 cells/mm3. Patients' characteristics were similar between the two groups except CD4. The probability of undetectable HIV RNA at 12, 24, 36, and 48 weeks were 57.1% (95% CI, 37.7-78.1%), 76.2% (95% CI, 56.9-91.3%), 80.9% (95% CI, 62.3-94.0%), and 90.5% (95% CI, 68.9-99.1%) for the former group; and 64.0% (95% CI, 45.8-81.8%), 92.0% (95% CI, 77.5-98.6%), 96.0% (95% CI, 83.0-99.7%), and 96.0%.(95% CI, 83.0-99.7%) for the latter group. Median time to undetectable HIV RNA was 12 weeks for both groups. Median CD4 change at 48 weeks was 171 and 132 cells/mm3, respectively (p = 0.232). The adverse events were similar between the two groups.CONCLUSION:
Initiation of EFV-based HAART regimen in HIV-infected patients at CD4 < 100 and > or = 100 cells/ mm3 gains similar immunological and virological response.
