Prevalence of transmitted HIV-1 drug resistance mutations in children and adolescents in São Paulo, Brazil

Abstract

HIV drug resistance genotype testing, performed on 39 HIV-infected treatment-naive children from 2000 to 2011, identified 5 children (12.8%) with drug resistance mutations: 5.3% to nucleoside reverse transcriptase inhibitors, 5.3% to nonnucleoside reverse transcriptase inhibitors and 7.7% to protease inhibitors. There was a trend for increasing prevalence of drug resistance mutations during the 11-year study period.
