Hepatology :DAA时代HCV/HIV共感染将不再难治

2017-11-13 佚名 国际肝病

既往,由于HCV和HIV合并感染的患者的抗HCV治疗效果不理想,持续病毒学应答(SVR)率较单纯HCV感染者低,而被定义为“特殊人群”。

既往,由于HCV和HIV合并感染的患者的抗HCV治疗效果不理想,持续病毒学应答(SVR)率较单纯HCV感染者低,而被定义为“特殊人群”。近日,美国加利福利亚大学Sikavi等完成的一项系统综述表明:在DAA时代,HCV-HIV共感染者与HCV感染者具有相似的高SVR率,需要重新考虑合并感染者的“特殊人群”定义,HCV-HIV共感染者不再是难治性人群。

研究者系统回顾了HIV感染者的慢性HCV感染治疗,在PubMed、EMBASE和Cochrane图书馆数据库中,检索于2004年1月至2017年7月发表的、包含关键词“hepatitis C”、“HIV”、“coinfection”和“direct-acting antiviral”的研究。

结果显示,采用基于干扰素方案治疗的HCV-HIV共感染者的SVR率明显低于单纯HCV感染者的SVR率;而接受DAA治疗的单纯HCV感染与合并感染者的SVR率相似(SVR率大于93%)(图1)。相比于含干扰素方案,DAA方案的安全性、疗效和耐受性均有改善;DAA弥补了干扰素时代合并感染者未能满足的医疗需求。



S: second-generation protease inhibitor;
FPI: first-generation protease inhibitor.

作者认为:需要重新考虑HCV-HIV共感染者是否属于“特殊人群”。无论患者是否合并HIV,DAA疗法均能使丙型肝炎患者获得较高的SVR率。但需要提醒大家的是,临床医生还必须了解SVR的负面预测因素,以及在合并感染人群中可能更为常见的治疗障碍。
