Popis: BACKGROUND: The accumulation of mutations after long-lasting exposure to a failing combination antiretroviral therapy (cART) is problematic and severely reduces the options for further successful treatments. METHODS: We studied patients from the Swiss HIV Cohort Study who failed cART with nucleoside reverse transcriptase inhibitors (NRTIs) and either a ritonavir-boosted PI (PI/r) or a non-nucleoside reverse transcriptase inhibitor (NNRTI). The loss of genotypic activity 6 months after virological failure was analyzed with Stanford algorithm. Risk factors associated with early emergence of drug resistance mutations (6 months after failure: 8.8% vs. 38.2% (p = 0.009), 7.1% vs. 46.9% (p6 months after failure compared to 41.2%, 49.0% and 63.0% of those who have lost NNRTI activity (all p
