Update of the Drug Resistance Mutations in HIV-1

Abstract

The International AIDS Society-USA (IAS-USA) Drug Resistance Mutations Group reviews new data on HIV-1 drug resistance that have been published or presented at recent scientific meetings to maintain a current list of mutations associated with antiretroviral drug resistance.This December 2008 version of the IAS-USA drug resistance mutations figures updates those published in this journal in March/April 2008 (Johnson VA, Brun-Vezinet F, Clotet B, et al, Top HIV Med, 2008;16:62-68). The compilation includes mutations that may contribute to a reduced virologic response to HIV-1 drugs. It should not be assumed that the list presented here is exhaustive. Drugs that have been approved by the US Food and Drug Administration (US FDA) as well as any drugs available in expanded access programs are included and listed in alphabetical order by drug class. The figures are designed for practitioners to use in identifying key mutations associated with viral resistance to antiretroviral drugs and in making therapeutic decisions.
