Prediction of HIV drug resistance based on virologic, immunologic, clinical, and/or adherence criteria in the Stratall ANRS 12110/ESTHER trial in Cameroon.

Our study in Cameroonian rural district hospitals showed that the immunologic and clinical failure criteria had poor performance to identify human immunodeficiency virus drug resistance in a timely manner. Switching to second-line antiretroviral therapy after 2 consecutive viral loads ≥5000 copies/mL, as recommended by the World Health Organization, appeared to be the most appropriate strategy.
