Clin Infect Dis:雷特格韦预防艾滋病的垂直传播

目前在大众的视角里,感染了艾滋病毒意味着“非良民”,会被社会舆论指指点点,是可耻的。或许他/她可以一个人藏着掖着,直到死亡湮灭心中的秘密。可是若是感染HIV的女性恰巧怀孕了,还能躲躲藏藏吗?她可以对自己不负责,可是不能对胎儿,对即将来临的新生命不(sang)闻(jin)不(tian)问(liang)。隐瞒病史、不接受正规治疗的孕妇的报道屡见不鲜,不仅让自己的孩子一出生就挂上“艾滋”的名号,更是让其

目前在大众的视角里,感染了艾滋病毒意味着“非良民”,会被社会舆论指指点点,是可耻的。或许他/她可以一个人藏着掖着,直到死亡湮灭心中的秘密。可是若是感染HIV的女性恰巧怀孕了,还能躲躲藏藏吗?她可以对自己不负责,可是不能对胎儿,对即将来临的新生命不(sang)闻(jin)不(tian)问(liang)。隐瞒病史、不接受正规治疗的孕妇的报道屡见不鲜,不仅让自己的孩子一出生就挂上“艾滋”的名号,更是让其一辈子都无法好好为人,终究会有很大一部分变成危害社会治安的隐患。可是这些是可以避免的。

雷特格韦,作为艾滋病抗病毒药物中第一个整合酶抑制剂,作用于HIV整合酶,阻止HIV复制而降低血液中HIV病毒载量,该药虽不能治愈艾滋病,但是确实对预防艾滋病毒母婴传播(MTCT)的重要手段之一,特别是当HIV病毒的RNA病毒载量快速下降,或者抗逆转录病毒不能使用时。

Blonk M等人进行了一项非盲、多中心的IV期研究(PANNA Network),让感染艾滋病毒的孕妇使用雷特格韦 400mg每日两次。根据孕晚期和分娩时药物浓度以及产后脐血药物浓度等数据分析雷特格韦的药物代谢动力学,同时评估该药的安全性和有效性。

该研究共纳入22名感染艾滋病毒的孕妇,有68%在孕期开始使用雷特格韦。接近分娩时有86%的孕妇检测不到病毒载量(< 50 copies/mL)。纳入人群中没有1名孕妇的后代感染了HIV。研究发现雷特格韦的暴露量高度可变。孕晚期整体AUC和C12h血里药物浓度比产后低29%和36%:AUC0-12h 的几何平均比率为0.71,95% CI 0.53-0.96;C12h的几何平均比率为0.64,95% CI 0.34-1.22。脐血和母亲血液里雷特格韦药物浓度的中位数(IQR)比率是1.21(1.02-2.17; n=9)。

研究结果表明,孕期使用雷特格韦是安全的,妊娠对其耐受良好。雷特格韦的药物代谢动力学变化性很大。研究观察到雷特格韦药物浓度在孕晚期要低于产后,但是目前还没有发现该现象的临床重要性。研究结果进一步表明,可以对感染艾滋病毒的孕妇使用标准剂量的雷特格韦,其实安全有效的。

Antivir Ther:雷特格韦与两个核苷类似物联合抗逆转录病毒治疗

背景: 由于药物间相互作用以及毒性反应的风险增加,对于艾滋病毒感染需要癌症化疗的患者,很少有关于最佳组合抗逆转录病毒疗法的数据。 方法: 我们评估30个艾滋病毒感染接受抗肿瘤药物治疗的患者,基于雷特格韦给药方案的药物间相互作用,及其安全性和疗效。 结果: 17个为非艾滋病的恶性肿瘤(7个霍奇金病)患者,13个有艾滋病毒相关的癌症(9个非霍奇金淋巴瘤,2个卡波西肉瘤,2个肛门癌)。总体来说,他们
