BACKGROUND/AIMS: Pegylated interferon (peginterferon) and ribavirin is the current standard therapy for chronic hepatitis C. The aims of this study were to evaluate the efficacy of peginterferon and ribavirin and to identify predictors of a sustained virological response (SVR) to the retreatment of chronic hepatitis C in Korea.
The clinical records of 91 patients with chronic hepatitis C who were retreated with peginterferon and ribavirin were retrospectively analyzed. None of the patients had previously attained a SVR, and the patients were categorized according to their previous responses (nonresponder, relapser, or inadequate treatment) to conventional interferon/ribavirin.
The overall SVR rate was 54.9%. Independent predictors of a SVR were genotypes 2 and 3, relapse, an adherence to peginterferon of over 80%, and an early virological response (EVR). For genotype 1 patients, an adherence to peginterferon of over 80% was an independent predictor of a SVR.
Peginterferon and ribavirin therapy is effective for the retreatment of Korean chronic hepatitis C patients who have failed interferon/ribavirin, especially in patients with genotypes 2 and 3, relapse, an adherence to peginterferon over 80%, and an EVR. For genotype 1 patients, retreatment was effective in patients with an adherence to peginterferon over 80%.
背景/目的:聚乙二醇干扰素(peginterferon)和利巴韦林是慢性丙型肝炎的当前标准治疗方法。本研究的目的是评估 peginterferon 和利巴韦林的疗效,并确定韩国慢性丙型肝炎再治疗中持续病毒学应答(SVR)的预测因素。
回顾性分析了 91 例接受 peginterferon 和利巴韦林再治疗的慢性丙型肝炎患者的临床记录。这些患者均未达到 SVR,且根据他们对常规干扰素/利巴韦林的既往反应(无应答者、复发者或治疗不足者)进行分类。
总的 SVR 率为 54.9%。SVR 的独立预测因素包括基因型 2 和 3、复发、peginterferon 的依从性超过 80%以及早期病毒学应答(EVR)。对于基因型 1 患者,peginterferon 的依从性超过 80%是 SVR 的独立预测因素。
聚乙二醇干扰素和利巴韦林治疗对干扰素/利巴韦林治疗失败的韩国慢性丙型肝炎患者再治疗有效,特别是在基因型 2 和 3、复发、peginterferon 的依从性超过 80%以及 EVR 的患者中。对于基因型 1 患者,peginterferon 的依从性超过 80%的患者再治疗有效。
