Implications of HIV drug resistance on first- and second-line therapies in resource-limited settings: report from a workshop organized by the Collaborative HIV and Anti-HIV Drug Resistance Network.

Here, we summarize the discussions and conclusions from an expert workshop held in October 2012 to consider the implications of HIV drug resistance in the context of scale-up of access to antiretroviral therapy and prophylaxis in resource-limited settings. Topics considered during the workshop included the implications of drug resistance for the selection of first-line regimens and sequencing of treatments, optimal surveillance strategies and prevention of mother-to-child transmission.
