Abstract Background Antiretroviral therapy (ART) has transformed HIV management, with various regimens available. Dolutegravir (DTG) plus lamivudine (3TC) dual therapy is now the one of the first line regimens. Methods A retrospective, observational study included treatment naïve people living with HIV (PLWH) with baseline HIV RNA viral load (VL) greater than 500,000 copies/mL from March 2020 to June 2022. PLWH on DTG + 3TC were included in the 2DR group, while others on INSTI-based three-drug regimens were divided in the 3DR group. Viral suppression, immunological recovery, and safety were assessed. Results The study included 52 PLWH, with no significant baseline differences. Virologic suppression rates at weeks 24 and 48 were similar in both groups, even with baseline HIV RNA VL greater than 1,000,000 copies/mL. CD4 + T cell counts improved rapidly. No serious adverse effects were reported. Conclusions DTG + 3TC dual therapy demonstrates effectiveness in treatment naïve PLWH with high baseline HIV RNA VL, suggesting its potential as a first line regimen for all treatment naïve PLWH.
