Triple nucleoside reverse transcriptase inhibitor- vs. nonnucleoside reverse transcriptase inhibitor-containing regimens as first-line therapy: efficacy and durability in a prospective cohort of French HIV-infected patients.
HIV MEDICINE(2005)
摘要
Objective Based on the short-term results of the AIDS Clinical Trials Group (ACTG) A5095 trial, zidovudine (ZDV)/lamivudine (3TC)/abacavir (ABC) is no longer recommended as a first-line antiretroviral regimen. Data on the efficacy of this triple nucleoside reverse transcriptase inhibitor (NRTI) combination compared with the gold-standard nonnucleoside reverse transcriptase inhibitor (NNRTI) regimen could provide important information. Methods Patients were selected from three prospective cohorts of patients who received first-line therapy with ZDV/3TC plus an NNRTI or ABC, started after January 1998. Immunovirological changes and the proportion of treatment discontinuations were compared between groups. Results Of the 380 patients, 190 started on ABC [the triple-NRTI group (3N)] and 190 on NNRTI. At baseline, there was no statistical difference between the NNRTI and 3N groups for age (mean = 38 years), sex (66% male) or CD4 cell count (mean = 305 cells/mu L). Mean baseline plasma HIV-1 viral load (pVL) was higher in the 3N group (4.6 vs. 4.3 log(10) HIV-1 RNA copies/mL: P < 0.01). Lower and higher estimates of median pVL decrease at month 24 were 2.05 and 4.76 log(10) copies/mL in the 3N group, and 1.73 and 4.31 log(10) copies/mL in the NNRTI group (not significant). CD4 cell count evolution did not differ between groups. Treatment discontinuation occurred in 45% vs. 44% of patients in the NNRTI and 3N groups, respectively, after median durations of 9 and 4 months, respectively (P = 0.02). Conclusions In this prospective cohort, 3N and NNRTI regimens as first-line therapy produced similar immunovirological responses.
