The burden of chronic hepatitis C virus (HCV) infection is significant and growing. HCV is considered one of the leading causes of liver disease worldwide and the leading cause of liver transplantation globally. While those infected is estimated in the hundreds of millions, this is likely an underestimation because of the indolent nature of this disease when first contracted. Approximately 20% of patients with HCV infection will progress to advanced fibrosis and cirrhosis. Those that do are at risk of decompensated liver disease including GI bleeding, encephalopathy, severe lab abnormalities, and hepatocellular carcinoma. Those individuals with advanced fibrosis and cirrhosis have historically been difficult to treat. The backbone of previous HCV regimens was interferon (IFN). The outcomes for IFN based regimens were poor and resulted in increased adverse events among those with advanced fibrosis and cirrhosis. Now, in the era of new direct acting antiviral (DAA's) medications, there is hope for curing chronic HCV in everyone, including those with advanced fibrosis and cirrhosis. This article provides a review on the most up to date data on the use of DAA's in patients with advanced fibrosis and cirrhosis. We are at a point where HCV could be truly eradicated, but to do so will require ensuring there are effective and safe treatments for those with advanced fibrosis and cirrhosis.
慢性丙型肝炎病毒(HCV)感染的负担十分巨大且仍在加重。HCV被认为是全球肝病的主要病因之一,也是全球肝移植的首要原因。虽然据估计受感染人数达数亿,但由于初次感染时该病具有隐匿性,这一数字可能被低估。约20%的HCV感染者会进展为重度肝纤维化和肝硬化。进展至此的患者有发生失代偿性肝病的风险,包括胃肠道出血、肝性脑病、严重实验室指标异常以及肝细胞癌。历史上,那些患有重度肝纤维化和肝硬化的个体一直难以治疗。以往HCV治疗方案的主要药物是干扰素(IFN)。基于IFN的治疗方案效果不佳,且导致重度肝纤维化和肝硬化患者的不良事件增多。如今,在新型直接抗病毒药物(DAA)的时代,有望治愈每一位慢性HCV感染者,包括那些患有重度肝纤维化和肝硬化的患者。本文对DAA用于重度肝纤维化和肝硬化患者的最新数据进行综述。我们正处于能够真正根除HCV的阶段,但要做到这一点,需要确保为那些患有重度肝纤维化和肝硬化的患者提供有效且安全的治疗方法。
