Abstract:
Tenofovir alafenamide (TAF)-based antiretroviral therapy (ART) regimens have been associated with adverse changes in lipid and glucose profiles compared with tenofovir disoproxil fumarate (TDF)-based ART, but data in pregnancy are limited. We evaluated metabolic markers in pregnant women with human immunodeficiency virus (HIV) after starting TAF- versus TDF-based ART. Methods We analyzed data within the IMPAACT 2010/VESTED trial, which demonstrated better pregnancy outcomes in pregnant women randomized to initiate TAF/Emtricitabine/Dolutegravir (TAF/FTC + DTG; n = 217) or TDF/FTC + DTG (n = 215). We measured non-fasting plasma concentrations of glucose, total-cholesterol, low-density lipoprotein-cholesterol (LDL-C), high-density lipoprotein-cholesterol (HDL-C), lipoprotein (a), and triglycerides from samples collected 8 weeks after enrollment. We employed linear regression models to estimate by-arm mean differences. Results In total, 219 participants enrolled in the DTG arms in Zimbabwe and Uganda: 109 in the TAF/FTC + DTG and 110 in the TDF/FTC + DTG arms. At study entry, mean gestational age was 22.6 weeks, median HIV-1 RNA was 711 copies/mL, and mean age was 25.8 years. By 8 weeks, mean total cholesterol was 12 mg/dL higher in women randomized to TAF/ FTC + DTG versus TDF/FTC + DTG (95% confidence interval [CI]: 3.8, 21.1). Pregnant women in the TAF/FTC + DTG arm had higher mean LDL-C (7.1 mg/dL, 95% CI: .2, 14.0), triglycerides (12.3 mg/dL, 95% CI: 1.8, 22.7), lipoprotein (a) (7.3 mg/dL, 95% CI: 1.1, 13.6), and lower mean HDL-C (2.8 mg/dL, 95% CI: .1, 5.6) compared to the TDF/FTC + DTG arm. Conclusions Pregnant women randomized to start TAF/FTC + DTG had higher lipids than those randomized to TDF/FTC + DTG within 8 weeks of ART initiation. However, lipid levels were within normal reference ranges.
