Abstract

Objective: To investigate the influence of genotypic resistance-guided HIV-treatment decisions on long-term clinical and virological outcomes in patients failing antiretroviral therapy by a prospective 30-month observation following a 6-month randomized study (Argenta trial). Methods: Patients (n=174) with virological failure on highly active antiretroviral therapy (HAART) were initially randomized (1:1) to receive empirical therapy or guidance by genotypic resistance results. After month 6, all patients with HIV RNA >1,000 copies/ml received genotypic resistance tests and expert advice. Predictors of virological and clinical outcomes were analysed by logistic regression and Cox's regression models. Results: There was a gradual increase in the proportion of patients with HIV RNA
