Abstract
BACKGROUND: The efficacy and safety of dolutegravir+lamivudine (DTG +3TC) and bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) have been demonstrated in clinical trials of treatment-naïve therapy. However, real-life data are lacking. We investigated and compared the virological outcomes and safety of DTG + 3TC with BIC/FTC/TAF in an adult cohort of people living with HIV (PLWH). RESEARCH DESIGN AND METHODS: We performed a retrospective cohort analysis of PLWH who were naïve to antiretroviral therapy and initiated the antiretroviral regimen of DTG + 3TC or BIC/FTC/TAF from January 2020 to March 2022. Treatment effectiveness, defined as the capability of treatment to achieve viral suppression (viral load < 50 copies/mL), was analyzed. Changes in immunology, metabolism, liver and renal function after 48 weeks of treatment were evaluated. RESULTS: = 0.3). No differences existed in immunology, metabolism, liver and renal function; however, BIC/FTC/TAF led to greater weight gain. CONCLUSIONS: Both optimization strategies showed high tolerability in antiretroviral therapy-naïve patients, with no differences in virological efficacy; however, BIC/FTC/TAF may be related to the risk of weight gain risk. Further research is required to evaluate this problem.
