摘要 目的评估血清HBsAg水平变化在预测干扰素α2b治疗慢性乙型肝炎患者停药后疗效的可行性。方法给予42例慢性乙型肝炎患者干扰素α2b治疗48 w,停药后随访24w。使用美国雅培公司生产的全自动生化分析仪检测血生化指标;采用PCR法检测血清HBV DNA;采用化学发光微粒子免疫测定法定量检测血清HBsAg水平。结果在48周治疗和随访24w结束时,10例(23.8%)完全应答,32例(76.2%)无应答,治疗前两组年龄、性别、ALT、HBV DNA载量、HBsAg水平无统计学差异(P>0.05);在13例治疗24 w时血清HBsAg<20000IU/ml患者中,9例(69.2%)在停药随访24w时出现完全应答,而在29例治疗24w时HBsAg定量>20000IU/ml患者中,仅有1例(3.4%)在停药随访24w时出现完全应答,两者有显著性差异(P<0.001);应用干扰素治疗24周血清HBsAg定量<20000IU/ml预测停药后的持续病毒学应答的曲线下面积为0.712,其阳性预测值为69.2%,阴性预测值为96.6%。结论治疗24周血清HBsAg水平可以作为优化干扰素α2b治疗慢性乙型肝炎患者的早期评估指标,对于治疗后其水平不下降者可以考虑及时停药。
