2、VRNA阴转的基因1型慢性丙型肝炎初治患者,随机分为两组,分别接受36w和48w治疗,在停药后随访24w,观察疗效。结果本研究共纳入40例患者,两组各20例。治疗36w患者在治疗结束时病毒学应答(ETvR)、持续病毒学应答(SVR)和复发率分别为100%(20例)、9O%(18例)和10%(2例),治疗48w患者ETVR、SVR和复发分别为95%(19例)、90%(18例)和5-3%(1例),两组比较无统计学差异(P>0.05);在4o例患者,基线HCVRNA水平与SVR呈负相关(OR=0.422,95%CI为0.05~0.29,P
3、=0.007);在治疗36w患者,基线HCVRNA<6x10IU/ml患者SVR显著高于HCVRNAI>6×10rlU/ml患者(P=0.005),但在治疗48w患者,未发现这种差异(P=0.063)。结论对于基线HCVRNA水平>400000IU/ml的基因1型慢性丙型肝炎初治患者,接受聚乙二醇干扰素ot一2a联合利巴韦林治疗,如在2w时获得病毒学应答,治疗36w疗程与48w疗程的SVR相当。【关键词】慢性丙型肝炎;干扰素ot一2a;极快速病毒学应答;疗效DOI:10.39696.issn.1672-5069.2014.05.01
