目的:CYP3A5、MDR1 (ABCB1) 和 OATP1 (SLCO1B1) 多态性与蛋白酶抑制剂的药代动力学 (PK) 变异相关。本研究的目的是探讨 CYP3A5 A6986G、ABCB1(C3435T 和 G2677T)和 SLCO1B1(T521C 和 A388AG)多态性对洛匹那韦/利托那韦(LPV/RTV)在 HIV 感染儿童中的 PK 和病毒学结果的影响。 设计和方法:我们对儿童(4-18 岁)进行了一项前瞻性队列研究。岁)接受 LPV/RTV 稳定抗逆转录病毒治疗。使用聚合酶链反应扩增和等位基因区分测定来确定 CYP3A5、ABCB1 和 SLCO1B1 基因型。使用非房室模型估计 LPV 和 RTV 浓度-时间曲线下的 12 小时血浆面积 (AUC) 和清除率 (CL)。每 12 周评估一次 HIV RNA 病毒载量,总研究期为 52 周。使用年龄和依从性调整以及 CL 异速调整的协方差模型分析来评估所研究的多态性与 AUC、CL 和 HIV RNA 之间的关联。 结果: 纳入了 50 名儿童(中位年龄 11.2 岁)。研究的基因型的等位基因频率处于哈迪-温伯格平衡状态。 LPV 或 RTV AUC 或 CL 与 CYP3A5、ABCB1 或 SLCO1B1 A388G 多态性之间没有统计学显着相关性。 SLCO1B1 T521C 基因型与 LPV AUC 增加之间存在显着相关性 (P = 0.042),与 LPV CL 降低之间存在近显着相关性 (P = 0.063)。在52周的研究随访期间,包括SLCO1B1 T521C在内的研究多态性均与病毒学结果无关。结论:CYP3A5、ABCB1或SLCO1B1 A388AG多态性对HIV感染儿童中LPV/RTV的PK和病毒学结果没有统计学上的显着影响。 SLCO1B1 T521C 多态性与 LPV AUC 的增加显着相关,但与研究期间检测不到的 HIV RNA 无关。
Objective:CYP3A5, MDR1 (ABCB1), and OATP1 (SLCO1B1) polymorphisms have been associated with variability in the pharmacokinetics (PK) of protease inhibitors. The aim of this study was to investigate the influence of CYP3A5 A6986G, ABCB1 (C3435T and G2677T), and SLCO1B1 (T521C and A388AG) polymorphisms on the PK and virologic outcome of lopinavir/ritonavir (LPV/RTV) in HIV-infected children.Design and Methods:We conducted a prospective cohort study in children (4-18 years old) on stable antiretroviral therapy with LPV/RTV. CYP3A5, ABCB1, and SLCO1B1 genotypes were determined using polymerase chain reaction amplification with allelic discrimination assays. The 12-hour plasma area under the concentration-time curves (AUC) and clearances (CL) of LPV and RTV were estimated using noncompartmental models. HIV RNA viral load was evaluated every 12 weeks for a total study period of 52 weeks. Analysis of covariance models with adjustment for age and adherence and allometric adjustment of CL were used to assess associations between studied polymorphisms and AUC, CL, and HIV RNA.Results:Fifty children (median age 11.2 years) were enrolled. Allele frequencies of the genotypes studied were in Hardy-Weinberg equilibrium. There was no statistically significant association between LPV or RTV AUC or CL, and CYP3A5, ABCB1, or SLCO1B1 A388G polymorphisms. There was a significant association between SLCO1B1 T521C genotype and increased LPV AUC (P= 0.042) and a nearly significant association with decreased LPV CL (P= 0.063). None of the studied polymorphisms, including SLCO1B1 T521C, were associated with virologic outcome during 52 weeks of study follow-up.Conclusions:There was no statistically significant influence of the CYP3A5, ABCB1, or SLCO1B1 A388AG polymorphisms on the PK and virologic outcome of LPV/RTV in HIV-infected children. SLCO1B1 T521C polymorphism was significantly associated with an increase in LPV AUC but was not associated with undetectable HIV RNA during the study period.
