摘 要:目的 研究利巴韦林累积剂量对基因1型慢性丙型肝炎患者病毒学应答率的影响.方法 对哈尔滨医科大学附属第二医院感染病科进行聚乙二醇干扰素α-2a联合利巴韦林治疗的225例基因1型慢性丙型肝炎患者进行回顾性分析.根据利巴韦林累积剂量将患者分为<60%、60%~79%、80%~97%和>97%4组,探讨利巴韦林累积剂量与病毒学应答率的关系.数据行F检验或x2检验.结果 利巴韦林累积剂量≤97%的发生率为43.1% (97/225例),明显高于聚乙二醇干扰素α-2a的27.1%(61/225例)(x2=12.641,P=0.001).利巴韦林累积剂量<60%组的18例患者中,5例有持续性病毒学应答(SVR),SVR率为27.8%明显低于>97%组的65.6%(84/128例)、80%~97%组的60.5%(26/43例)和60%~79%组的58.3%(21/36例)(x2=9.538,P=0.023).利巴韦林累积剂量<60%组获得治疗结束时病毒学应答(ETVR)的13例患者中,8例复发,复发率明显高于>97%组的20.0%(21/105例)、80%~97%组的23.5%(8/34例)和60%~79%组的27.6%(8/29例)(x2=10.837,P=0.013).在获得快速病毒学应答(RVR)的患者中,利巴韦林累积剂量>97%组为25例、80%~97%组为9例、60%~79%组为7例、<60%组为4例,SVR分别为23(92.0%)、8、6和3例(x2=1.098,P=0.778).结论 轻度利巴韦林减量不影响基因1型慢性丙型肝炎患者的SVR,利巴韦林累积剂量<60%的患者复发率高,SVR率低. 关键词:肝炎,丙型,慢性;利巴韦林;剂量效应关系,药物;基因,病毒

Abstract:Objective To study the impact of ribavirin cumulative dose on virological response rates in genotype 1 hepatitis C virus(HCV)infected patients.Methods The medical records of 225 genotype 1 chronic hepatitis C(CHC)patients treated with peginterferon α-2a plus ribavirin were retrospectively analyzed.These patients were divided into four groups according to[1] [2] [3] 下一页 上一个医学论文: 干扰素α与阿德福韦酯不同联合方法治疗HBeAg阳性慢性乙型肝炎的疗效 下一个医学论文: 两种实时荧光定量聚合酶链反应检测血清HCV RNA的比较
