An estimated 3.5 million people in the United States have chronic hepatitis C. Each year, 8,000 to 10,000 of these chronically infected patients die of a liver-related complication of their infection. The introduction of effective blood screening assays has resulted in a remarkable decrease in the incidence of post-transfusion HCV infection. Nonetheless, hepatitis C remains an important clinical problem. Some important new treatment programs can help prevent the development and progression of compensated cirrhosis to either decompensated cirrhosis or HCC. Patients who present to the health care system with advanced chronic active hepatitis or cirrhosis have been treated with interferon. Of those studied, only IFN therapy has been shown to induce remissions of the hepatic inflammatory process and to eliminate viral infection in most treated cases. However, it is widely held assumption that cirrhotic individuals do not respond to IFN therapy and that the treatment of decompensated cirrhotic individuals with HCV infection is dangerous. We believe that this assumption is false. In many studies, cirrhotic patients with chronic hepatitis C have been shown to respond to IFN therapy. However, they do so at a rate of half that reported for individuals with non-cirrhotic chronic active hepatitis. There have been no reports of hepatic decompensation as a consequence of IFN treatment of cirrhotic individuals with chronic hepatitis C. The use of IFN for cirrhotic patients is reviewed.
据估计,美国有350万人患有慢性丙型肝炎。每年,这些慢性感染患者中有8000至10000人死于与感染相关的肝脏并发症。有效的血液筛查检测方法的引入,已使输血后丙型肝炎病毒(HCV)感染的发生率显著下降。尽管如此,丙型肝炎仍然是一个重要的临床问题。一些重要的新治疗方案有助于预防代偿期肝硬化发展和进展为失代偿期肝硬化或肝细胞癌(HCC)。患有晚期慢性活动性肝炎或肝硬化的患者已接受干扰素治疗。在这些研究对象中,只有干扰素疗法已被证明能在大多数治疗病例中诱导肝脏炎症过程缓解并消除病毒感染。然而,人们普遍认为肝硬化患者对干扰素疗法无反应,且用干扰素治疗HCV感染的失代偿期肝硬化患者是危险的。我们认为这种假设是错误的。在许多研究中,慢性丙型肝炎肝硬化患者已被证明对干扰素疗法有反应。然而,他们的反应率是非肝硬化慢性活动性肝炎患者报告反应率的一半。尚无因用干扰素治疗慢性丙型肝炎肝硬化患者而导致肝失代偿的报道。本文对肝硬化患者使用干扰素的情况进行了综述。
