CHAIN Minority HIV-1 Variants Working Group

Data: 2014
Resum: It is still debated if pre-existing minority drug-resistant HIV-1 variants (MVs) affect the virological outcomes of first-line NNRTI-containing ART. This Europe-wide case-control study included ART-naive subjects infected with drug-susceptible HIV-1 as revealed by population sequencing, who achieved virological suppression on first-line ART including one NNRTI. Cases experienced virological failure and controls were subjects from the same cohort whose viraemia remained suppressed at a matched time since initiation of ART. Blinded, centralized 454 pyrosequencing with parallel bioinformatic analysis in two laboratories was used to identify MVs in the 1%-25% frequency range. ORs of virological failure according to MV detection were estimated by logistic regression. Two hundred and sixty samples (76 cases and 184 controls), mostly subtype B (73. 5%), were used for the analysis. Identical MVs were detected in the two laboratories. 31. 6% of cases and 16. 8% of controls harboured pre-existing MVs. Detection of at least one MV versus no MVs was associated with an increased risk of virological failure (OR = 2. 75, 95% CI = 1. 35-5. 60, P = 0. 005); similar associations were observed for at least one MV versus no NRTI MVs (OR = 2. 27, 95% CI = 0. 76-6. 77, P = 0. 140) and at least one MV versus no NNRTI MVs (OR = 2. 41, 95% CI = 1. 12-5. 18, P = 0. 024). A dose-effect relationship between virological failure and mutational load was found. Pre-existing MVs more than double the risk of virological failure to first-line NNRTI-based ART.
