Background: We aimed to examine the evolution of blood lipids and compare the risk of dyslipidemia between antiretroviral-naive people living with HIV who received tenofovir disoproxil fumarate (TDF), lamivudine (3TC), and efavirenz (EFV) (TDF + 3TC + EFV) and those who received coformulated elvitegravir, cobicistat, emtricitabine, and tenofovir alafenamide (E/C/F/TAF)., Methods: We retrospectively reviewed the medical records of 2343 antiretroviral-naive people living with HIV who initiated TDF + 3TC + EFV or E/C/F/TAF. A propensity score matching method was used to compare longitudinal changes of blood lipids between the 2 groups., Results: By using 1:3 matching ratio, we included 253 and 91 matched patients in TDF + 3TC + EFV group and E/C/F/TAF group, respectively. The levels of total cholesterol, triglyceride, low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol were higher in E/C/F/TAF group than those in TDF + 3TC + EFV group at 3, 6, 9, and 12 months (Wilcoxon test, all Ps < 0.05), except for high-density lipoprotein cholesterol at 9 and 12 months. The cumulative rates of hypercholesterolemia, hypertriglyceridemia, and high LDL-C in PLWH with normal lipid levels in E/C/F/TAF group were higher than those in TDF + 3TC + EFV group (hypercholesterolemia, 59.7% vs 21.5%, P < 0.001; hypertriglyceridemia, 69.5% vs 46.3%, P < 00.001; and high LDL-C, 41.5% vs 14.2%, P < 0.001). Multivariate analysis showed treatment with E/C/F/TAF was associated with a significantly higher risk of hypercholesterolemia [adjusted hazard ratio (HR), 4.12; 95% confidence interval (CI): 2.65 to 6.41], hypertriglyceridemia (adjusted HR, 1.69; 95% CI: 1.18 to 2.43), and high LDL-C (adjusted HR, 4.60; 95% CI: 2.66 to 7.97)., Conclusions: We concluded that treatment with E/C/F/TAF resulted in higher risks of dyslipidemia compared with TDF + 3TC + EFV., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2022 Wolters Kluwer Health, Inc.

Background: Some inpatients with HIV-RNA ≥500,000 copies/mL in China need to use 2-drug regimen for some reasons, although limited data are available for dolutegravir plus lamivudine (3TC) in those patients with ultra-high viral loads., Methods: We conducted a single-center retrospective-prospective study in China and enrolled 42 ART-naive HIV-infected inpatients who use a once-daily 2-drug regimen because of various reasons (drug interaction, renal impairment, age, and other related comorbidities).They were divided into 2 groups, low viral load group (baseline viral load <500,000 copies/mL, n = 20) and high viral load group (baseline viral load ≥500,000 copies/mL, n = 22). All patients were followed up for 48 weeks., Results: The median of baseline viral load was 5.74 log10 copies/mL and CD4+ T-cell count was 59 cells/μL. At week 48, there was no significant difference (P = 0.598) in proportions of participants with HIV-1 RNA <50 copies/mL [90%, 95% confidence interval (CI) (75.6% to 104.4%) in low viral load groups vs 95.5%, 95% CI (86.0% to 104.9%) in high viral load groups]. No differences were found in mean increase of CD4+ T-cell count from baseline between 2 groups (218 ± 122 vs 265 ± 127 cells/μL, P = 0.245). There is no grade 3 or higher treatment-related adverse events and none discontinued treatment because of adverse events., Conclusions: The results of our study in real world support dolutegravir + 3TC dual regimen as a promising therapy option for treatment-naive HIV-infected patient with baseline viral load ≥500,000 copies/mL., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2022 Wolters Kluwer Health, Inc.
