EASL 2014:DCV+SOF可有效治疗HCV基因1,2,3型感染者

2014-05-13 佚名 dxy

超过90%各种HCV基因型感染患者在使用DCV60mg+ SOF400mg每天±利巴韦林每天两次进行治疗,在12或24周后达到了持续性病毒学反应。该研究报道的是所有患者的耐药性检测结果。 该研究共纳入了211例患者。(126例为基因型1型的初治患者,44 例为基因型2/3初治患者,41例基因型1型患者既往进行telaprevir或boceprevir治疗)。研究人员对基线和治疗失败的病人进行测序,

超过90%各种HCV基因型感染患者在使用DCV60mg+ SOF400mg每天±利巴韦林每天两次进行治疗,在12或24周后达到了持续性病毒学反应。该研究报道的是所有患者的耐药性检测结果。

该研究共纳入了211例患者。(126例为基因型1型的初治患者,44 例为基因型2/3初治患者,41例基因型1型患者既往进行telaprevir或boceprevir治疗)。研究人员对基线和治疗失败的病人进行测序,研究NS5A和NS5B抗性相关的多态性。

211例患者中,只有1例出现病毒学突破(基因型3型),2例为治疗后复发(基因1a 型和基因型3型)。耐药性分析只在复发者中进行。基因1a型的复发者在治疗接受时没有出现NS5A和NS5B的耐药相关性多态性。

系统发育分析提示为再感染,而不是复发。基因型3型复发的患者在基线和治疗失败时检测到NS5A耐药性相关多态性。克隆分析和深度测序(<1%)可检测到较少的NS5B 突变体。

有33/203例患者在基线检测到NS5A的耐DCV多态性。共有32例实现SVR,1例复发。31/196例患者在基线检测到NS5B RAP。他们都实现了SVR。既往TVR/BOC治疗失败的患者中,19/41例基线检测到NS3 RAPs ,并都实现SVR。

该研究结果表明,无干扰素/利巴韦林的DCV+SOF口服药物组合,可使既往NS3蛋白酶抑制剂治疗失败,不依赖于基线检测到NS5A的HCV基因1,2,3型感染者获得较高的病毒学应答率。
