Abstract

Atazanavir-ritonavir concentrations change over time during pregnancy in HIV-positive patients; the impact of genetic variants is unknown. Twenty patients were enrolled in this study; plasma and intracellular concentrations of antiretrovirals were measured, in addition to single-nucleotide polymorphisms in transport-related genes. Linear logistic regression showed that genetic variants in organic-anion-transporter-1B1- and pregnane-X-receptor-encoding genes affected third-trimester atazanavir exposure. In this prospective study, genetic variants partially explained the observed interpatient variability in third-trimester exposure to antiretrovirals.

摘要

在感染 HIV 的孕妇中,阿扎那韦-利托那韦的浓度会随时间而变化;遗传变异的影响尚不清楚。本研究共纳入 20 例患者;除了转运相关基因的单核苷酸多态性外,还检测了抗逆转录病毒药物的血浆和细胞内浓度。线性逻辑回归显示,有机阴离子转运蛋白 1B1 和妊娠相关 X 受体编码基因的遗传变异影响了阿扎那韦在孕晚期的暴露。在这项前瞻性研究中,遗传变异部分解释了抗逆转录病毒药物在孕晚期观察到的个体间变异性。
