- Abstract
Objective: To evaluate the association of antiretroviral therapy (ART) type and duration of exposure with early placental function using biomarkers of aneuploidy screening. Study design: Three hundred thirty-eight pregnant women living with HIV were enrolled in two Canadian centers. Multiple linear regressions were performed adjusting for confounding factors (race, age, gestational age, body mass index, parity, smoking, and fetal sex). Results: Women receiving ART had significantly increased second trimester alpha-fetoprotein (AFP) levels ( β = 0.147, 95% CI = [0.067-0.227] for protease inhibitor-based ART and β = 0.176, 95% CI = [0.080-0.272] for ART without protease inhibitor) compared to women who received no treatment. However, there was no significant association between ART type and the levels of free β-human chorionic gonadotrophin (β-hCG), pregnancy-associated plasma protein-A (first trimester), unconjugated estriol, total hCG, and inhibin A (second trimester). No significant association was shown between biomarker levels and duration of ART exposure. Conclusion: Early placental function does not appear to be significantly affected by ART, except for AFP.
