NEJM:度鲁特韦联合富马酸替诺福韦治疗HIV

2019-08-29 MedSci MedSci原创

DTG联合两种替诺福韦前药(TAF和TDF)对HIV的治疗效果与标准护理方案相当

近日研究人员考察了度鲁特韦(DTG)联合富马酸替诺福韦(TAF)在中低收入国家治疗HIV的效果。

研究人员在南非开展,12岁以上,先前6个月未接受ART治疗,HIV RNA水平为500拷贝/毫升以上患者随机接受FTC(恩曲他滨)+DTG+TAF、FTC+DTG+TDF(替诺福韦艾拉酚胺)或TDF-FTC- efavirenz(依非韦仑,标准治疗组)。研究的主要终点是48周HIV-1 RNA水平低于50拷贝/毫升的患者百分比。

1053名患者参与研究,平均年龄32岁,平均CD4细胞数为337个/立方毫米。在48周时,每毫升少于50拷贝的HIV-1 RNA水平的患者百分比在TAF组为84%,在基于TDF的组中为85%,在标准护理组中为79%,达到非劣性终点。标准护理组提前中止试验患者的数量高于其他两组。TAF方案对骨密度和肾功能的影响小于其他治疗方案,TAF组和女性患者体重增加显著(TAF组平均增加6.4kg,TDF组增加3.2kg,标准护理组增加1.7kg)。在接受含DTG方案的患者中,未发现对整合酶抑制剂的耐药性。

研究发现,DTG联合两种替诺福韦前药(TAF和TDF)对HIV的治疗效果与标准护理方案相当。
