First-line highly active antiretroviral regimens in 2001-2002 in the French Hospital Database on HIV: combination prescribed and biological outcomes.: First-line haart : combination prescribed and biological outcomes.

Abstract

INTRODUCTION: We compared biological outcomes in antiretroviral-naive patients with viral load (VL) > 5,000 copies/ml starting combivir-based, three-drug highly active antiretroviral therapy regimens in 2001-2002 according to the third component, namely abacavir (ABC), nelfinavir (NFV), indinavir/ritonavir (IDV/r), lopinavir/ritonavir (LPV/r), nevirapine (NVP) or efavirenz (EFV). METHODS: We evaluated virological response (HIV RNA or = 50 CD4+ T-cells/microl) separately in patients with baseline VL or = 100,000 copies/ml, the virological efficacy of EFV was similar to that of NVP (0.90) and LPV/r (0.97) and better than that of NFV (0.62), ABC (0.75) and IDV/r (0.78). The immunological results found in these patients were similar to those observed in patients with baseline VL < 100,000 copies/ml. CONCLUSIONS: For first-line therapy, in this observational setting, EFV, LPV/r and NVP, when added to the combivir backbone, were more likely to drive viral load < 500 copies/ml. LPV/r showed the best immunological effectiveness
