Lancet Infect Dis:依法韦仑治疗HIV感染的安全性

2015-04-20 徐媛媛译 MedSci原创

背景:通过ENCORE1实验主要分析确立了联合替诺福韦和恩曲他滨时,400毫克依法韦仑和600毫克表针剂量依法韦仑组在96周时依法韦仑的非劣效性和安全性。 方法:ENCORE1是一项双盲、安慰剂对照、非劣效性试验在13个国家开展了38项临床实验基地。感染艾滋病病毒的成人患者(≥16岁)没有先前的抗逆转录病毒治疗,CD4细胞计数为50~500个/ μL和HIV-1血浆病毒载量≥1000拷贝/毫升的

背景:通过ENCORE1实验主要分析确立了联合替诺福韦和恩曲他滨时,400毫克依法韦仑和600毫克表针剂量依法韦仑组在96周时依法韦仑的非劣效性和安全性。

方法:ENCORE1是一项双盲、安慰剂对照、非劣效性试验在13个国家开展了38项临床实验基地。感染艾滋病病毒的成人患者(≥16岁)没有先前的抗逆转录病毒治疗,CD4细胞计数为50~500个/ μL和HIV-1血浆病毒载量≥1000拷贝/毫升的HIV成人感染患者按1:1的比例被随机分配至:每日300mg固定剂量的替诺福韦+200mg恩曲他滨+每日400mg依法韦仑组或者600mg依法韦仑组。参与者,医生和所有其他人员在治疗过程中多必须带着盲法。随机将hiv-1病毒载量在基线时(≤或> 100 000拷贝/毫升)进行分层。主要终点是在96周时两治疗组血浆中的HIV-1病毒载量低于200拷贝/毫升的患者比例。经过被修改治疗分析后,两者的病毒载量差值下限>-10%时(95%置信区间(CI))被认为是非劣效性。我们总结了治疗组的不良事件和严重不良事件。

结论:本文收纳了在2011年8月24日至2012年3月19日636名符合要求的参与者并随机分配到两个治疗组(324名400毫克依法韦伦和312名600毫克依法韦伦)。接受至少一个剂量的药物意向治疗的有630名患者,其中400mg依法韦仑组321名,600mg依法韦仑组309名。585名患者(299例400mg依法韦仑组患者、286例600mg依法韦仑组患者)完成了96周随访。 在96周时,在321名400mg依法韦仑组中289名(90•0%)患者和309例600mg依法韦仑组患者中280名(90•6%)患者的HIV-1病毒载量低于200拷贝/毫升(差异−0•6,95% CI −5•2~4•0;P=0•72), 这表明低剂量依法韦仑具有非劣效性。在不管基线血浆病毒载量情况下,记录非劣效性阈值不到50拷贝/毫升和不到400拷贝/毫升。在321例400mg依法韦仑组中有287名患者(89%)和在309例600mg依法韦仑组中有276名(89%)患者都发生了不良事件(P=0•97)。在两组中,所报告的不良反应与依法韦仑治疗相关患者人数分别为121 (38%)和148 (48%)(P=0•01)。在这些报告中重度不良反应的患者人数组间没有差异性(P=0•20)。

结果表明,在联合替诺福韦和恩曲他滨作为HIV初始疗法治疗96周时,400mg依法韦仑的治疗效果并不劣于600mg标准剂量的依法韦仑。与600mg依法韦仑组相比,400mg依法韦仑组的依法韦仑发生相关不良事件较少。这些研究结果支持常规应用400mg依法韦仑。利福平和400mg依法韦仑联合用药的情况还需要开展更深入研究。
