摘要 目的观察聚乙二醇干扰素α-2a(PEG—IFNa-2a)治疗慢性乙型肝炎(CHB)的疗效,探讨持久免疫控制的临床研究。方法76例CHB患者(HBeAg阳性43例,HBeAg阴性33例)使用PEG—IFNα-2a皮下注射,每次180恤g,每周1次,基本疗程为48周。治疗结束后随访48周。观察治疗结束时及结束后24、48周的应答情况。结果治疗48周时,HBeAg阳性组治疗患者丙氨酸氨基转移酶(ALT)复常率(90.6%)高于HBeAg阴性组(77.4%);治疗48周时,HBVDNA转阴率78.1%,高于HBeAg阴性组(54.8%);从治疗结束至随访48周,HBeAg阳性患者的持续应答率为37.2%,HBeAg阴性患者的持续应答率为87.9%,阴性组显著高于阳性组,两组比较差异有统计学意义(P〈0.05)。结论PEG—IFNα-2α具有免疫调节和抗病毒的双重作用,48周时HBeAg血清学转换率和HBV—DNA阴转率与治疗前血清ALT水平相关,停药后具有持续应答效应。
