近年来的研究表明,α-干扰素(IFN)对部分慢性丙型肝炎(CHC)有效,其应答率可达50%,应答率与年龄、性别、感染时间、感染方式、肝组织学表现、HCVRNA水平及病毒基因型等因素有关。最近的研究表明,铁也影响着CHC对IFN的应答〔1〕,用去铁的静脉放血疗法可提高部分患者的应答率。本 Recent studies have shown that alpha-interferon (IFN) is effective in partial chronic hepatitis C (CHC) and its response rate is up to 50%. The response rate is related to age, gender, infection time, infection pattern, HCVRNA levels and virus genotypes and other factors. Recent studies have shown that iron also affects the response of CHC IFN [1], with iron removal of venous bleeding therapy can improve the response rate in some patients. this
