摘要 目的研究慢性乙型肝炎经拉米夫定(LVD)治疗出现YMDD变异后,病情的进展及观察继续服用LVD并加强保肝治疗的疗效及安全性。方法78例YMDD变异患者采用继续服用LVD并加用双环醇片或水飞蓟素胶囊治疗48周,观察病情变化及转归。结果出现YMDD变异后,HBVDNA反弹的患者占93.6%(73/78),ALT升高者89.7%(70/78);轻度黄疸者25.6%(20/78);7例患者中途自行停用LVD,5例于停药后3~5个月出现重型肝炎的表现,其中2例死亡。本组治疗48周后ALT水平虽有下降,但ALT复常率为12.7%(9/7]),HBVDNA较基线下降0.45loglOcopies/ml,无HBeAg/HBeAb血清转换。结论YMDD变异后大部分患者临床表现轻微;变异后继续LVD及保肝治疗短期内未见病情恶化,但患者ALT复常率、病毒学应答率、血清学应答率低,在无有效抗病毒药物继续治疗的情况下, 停止LVD治疗存在病情恶化的风险。
