在过去几年中,抗丙型肝炎病毒(hepatitis C virus,HCV)治疗药物的研发取得了突破性进展。大量基础和临床研究证实,针对病毒蛋白的直接抗病毒药物(direct-acting antivirals,DAAs)能有效治疗HCV感染,获得高达90%以上的持续病毒应答(sustained viral response,SVR)。然而,由于诸多因素的影响,HCV合并人类免疫缺陷病毒(human immunodeficiency virus,HIV)感染的患者尚未得到有效的抗HCV治疗。在此将重点简述了DAAs的分类、作用机制及其临床试验效果;此外,还介绍了宿主靶向药物(host-targeting agents,HTAs)的研发情况,以及DAAs在HCV合并HIV患者中的临床应用进展。
【英文摘要】
In the past several years,research on the development of new drugs for treatment of hepatitis C virus infection has made a breakthrough. A number of basic and clinical studies have proven that direct-acting antivirals( DAAs)that target specific viral proteins are highly effective in treating HCV with a sustained viral response( SVR) as high as >90%. However,HCV / HIV co-infected individuals have not been able to receive the effective treatment with DAAs due to a number of factors. This paper briefly describ...
丙型肝炎病毒(hepatitis C virus,HCV)是在世界范围内流行程度高居第二的肝炎病毒,全球已有近2亿人感染HCV,占世界总人口的近3%[1]。更重要的是,大多数HCV感染者(75%~85%)不能完全清除体内病毒,并将转为慢性感染,而这其中5%~25%的患者最终会发展为肝硬化和肝癌[2]。在欧美西方?
