背景:在慢性丙型肝炎病毒(HCV)感染患者中,单独使用聚乙二醇干扰素α-2a治疗比单独使用干扰素α-2a治疗产生显着更高的持续病毒学应答。我们比较了聚乙二醇干扰素 α-2a 加利巴韦林、干扰素 α-2b 加利巴韦林和单独聚乙二醇干扰素 α-2a 在慢性丙型肝炎初始治疗中的疗效和安全性。 方法:共有 1121 名患者被随机分配接受治疗,并接受至少一剂研究药物,包括每周一次 180 微克聚乙二醇干扰素 α-2a 加每日利巴韦林(1000或 1200 mg,取决于体重),每周一次聚乙二醇干扰素 alfa-2a 加每日安慰剂,或每周三次 300 万单位干扰素 alfa-2b 加每日利巴韦林,持续 48 周。 结果:接受聚乙二醇干扰素 alfa-2a 加利巴韦林治疗的患者出现持续病毒学应答(定义为停止治疗 24 周后未检测到 HCV RNA)的患者比例显着高于接受治疗的患者。接受干扰素 alfa-2b 加利巴韦林治疗的患者(56% vs. 44%,P
Background: Treatment with peginterferon alfa-2a alone produces significantly higher sustained virologic responses than treatment with interferon alfa-2a alone in patients with chronic hepatitis C virus (HCV) infection. We compared the efficacy and safety of peginterferon alfa-2a plus ribavirin, interferon alfa-2b plus ribavirin, and peginterferon alfa-2a alone in the initial treatment of chronic hepatitis C.Methods: A total of 1121 patients were randomly assigned to treatment and received at least one dose of study medication, consisting of 180 microg of peginterferon alfa-2a once weekly plus daily ribavirin (1000 or 1200 mg, depending on body weight), weekly peginterferon alfa-2a plus daily placebo, or 3 million units of interferon alfa-2b thrice weekly plus daily ribavirin for 48 weeks.Results: A significantly higher proportion of patients who received peginterferon alfa-2a plus ribavirin had a sustained virologic response (defined as the absence of detectable HCV RNA 24 weeks after cessation of therapy) than of patients who received interferon alfa-2b plus ribavirin (56 percent vs. 44 percent, P
