RT Journal Article T1 Virological Failure in HIV to Triple Therapy With Dolutegravir-Based Firstline Treatment: Rare but Possible. A1 Pena, M J A1 Chueca, N A1 D'Avolio, A A1 Zarzalejos, J M A1 Garcia, F K1 dolutegravir K1 failure K1 firstline AB We describe a case of virological failure during initial treatment with tenofovir disoproxil fumarate/emtricitabine/dolutegravir twice daily, with concomitant rifampin treatment of staphylococcal infection, selection of R263K + E157Q, and low plasma dolutegravir levels. Using rifampin together with dolutegravir may require closer follow-up, and, if possible, plasma dolutegravir levels should be monitored.
