Hepatitis C virus (HCV) infection is a serious problem worldwide. The use of interferon-based therapy has made HCV eradication challenging. The recent appearance of direct-acting antiviral agents (DAAs) has changed HCV therapy. Combining the use of DAAs with peginterferon and ribavirin has improved treatment efficacy. Furthermore, the combination of different orally administered DAAs has enabled interferon-free therapy with much higher efficacy and safety. In particular, sofosbuvir, a nucleotide-based NS5B inhibitor, prevents HCV RNA synthesis by acting as a "chain terminator". Treatment with sofosbuvir has attained an extremely high rate of sustained virologic response. The current review summarizes the efficacy and safety of sofosbuvir therapy.
丙型肝炎病毒(HCV)感染是一个全球性的严重问题。基于干扰素的治疗方法使得根除HCV具有挑战性。直接作用抗病毒药物(DAA)的近期出现改变了HCV治疗格局。将DAA与聚乙二醇干扰素和利巴韦林联合使用提高了治疗效果。此外,不同口服DAA的联合使用使得无需干扰素治疗成为可能,且疗效和安全性更高。特别是,基于核苷酸的NS5B抑制剂索磷布韦通过充当“链终止剂”来阻止HCV RNA合成。索磷布韦治疗已实现极高的持续病毒学应答率。本综述总结了索磷布韦治疗的疗效和安全性。
