Viremia and HIV Drug Resistance among People Receiving Dolutegravir Versus Efavirenz-Based First-Line Antiretroviral Therapy

SUMMARY Limited data exists to inform management of viraemia among people receiving dolutegravir-based first-line ART in low- and middle-income countries. Among South-Africans with viraemia ≥1000copies/mL receiving dolutegravir (n=43) and efavirenz (n=37), we found no dolutegravir resistance, but high efavirenz resistance (66.7%). 12-week resuppression was higher with dolutegravir (85%) versus efavirenz (38%).
