Abstract

The aim of this study was to evaluate the prevalence of genotypic resistance for each drug-class, and of single resistance-mutations in 1,075 HIV-1 infected multi-treated patients undergoing their first genotypic resistance-test (GRT) after virological failure, over the years 1999-2003. First GRT was requested in 2003 for patients at earlier stages of failure, with less advanced disease, higher CD4-cell-count, lower HIV-RNA, and lower drug-experience with respect to 1999. Prevalence of resistance to all three drug-classes decreased from 33.3% in 1999 to 14.8% in 2003 (p
