Genotypic resistance profiles of HIV-2-infected patients from Cape Verde failing first-line antiretroviral therapy

The pol gene from HIV-2-infected patients from Cape Verde experiencing virologic failure was sequenced and drug resistance mutations were determined. Most patients were taking a first-line regimen of zidovudine (AZT), lamivudine (3TC) and lopinavir/ritonavir (LPV/r). Resistance mutations were found in most patients (11/17; 64.7%) especially I82F (4/7; 57.1%) and M184V (10/17; 58.8%). Resistance to all reverse transcriptase and protease inhibitors was found in 58.8% (10/17) of the patients. Integrase inhibitors are warranted to treat these patients.
