Introduction This study aimed to evaluate the prevalence of HIV-1 mutation V179D/E and the effect of V179D/E on the virological response to first-line efavirenz-based regimens among antiretroviral treatment (ART)-naive patients. Methods An ambispective cohort study was conducted. All ART-naive patients who underwent baseline genotypic resistance testing between January 2019 and November 2021 were included in the analysis of the prevalence of the V179D/E mutation. Then, patients with identified V179D/E received the efavirenz-based regimen or the protease inhibitor (PI)/integrase strand transfer inhibitor (INSTI)-based regimen. The virological and immunological outcomes at week 48 were compared between the two groups. Results HIV-1 mutation V179D/E was identified in 252 out of 2568 ART-naive patients, with a prevalence of 9.8% in Shanghai, China. A total of 206 participants were included in the efficacy analysis. Forty-six patients with altered ART regimens or incomplete follow-up data were excluded from the analysis. The baseline characteristics were comparable between the efavirenz group (n = 109) and the PI/INSTI group (n = 97). At week 48, a total of 96 participants (88.1%) in the efavirenz group and 92 participants (94.8%) in the PI/INSTI group had a viral load lower than 50 copies/mL (chi-square test, p = 0.086). In both groups, a lower proportion of participants achieved virological suppression among participants with a baseline viral load of at least 100,000 copies/mL compared with those with lower than 100,000 copies/mL (66.7% vs. 96.1% in the efavirenz group, p < 0.001; 87.1% vs. 98.4% in the PI/INSTI group, p = 0.039). The median increase from baseline in the CD4 count at week 48 was significantly greater in the PI/INSTI group (192 cells/mu L) than in the efavirenz group (154 cells/mu L) (p = 0.029). Conclusion There is a high prevalence of V179D/E in ART-naive patients with HIV-1 in Shanghai, China. The first-line efavirenz-based regimen may be not suitable for patients with HIV-1 mutation V179D/E, especially for those with a baseline viral load of at least 100,000 copies/mL. The study was registered at the Chinese Clinical Trial Registry (ChiCTR2000034787).
