摘要 目的探讨阿德福韦酯(ADV)联合拉米夫定(LAM)治疗LAM耐药慢性乙型肝炎(CHB)患者的疗效。方法选择LAM治疗后出现YMDD变异的HBeAg阳性CHB患者120例,随机分为ADV+LAM组(A组)90例,予ADV 10 mg/d联合LAM 100 mg/d口服;ADV组(B组)30例,给予ADV 10 mg/d口服,观察治疗12、24、48、96、144和192周时肝功能、血清HBVDNA水平、HBV血清标志物及不良反应。结果治疗12、24、48、96、144和192周A组ALT复常率分别为32(36.4%)、46(51%)、64(71.1%)、88(97.8%)、90(100%)、90(100%);B组分别为10(33.3%)、16(46.7%)、16(61.5%)、16(61.5%)、15(53.6%)、14(50%)(P<0.05);HBVDNA转阴率A组分别为32(36.4%)、82(91.1%)、88(97.8%)、88(97.8%)、88(97.8%)、88(97.8%),B组分别为11(36.6%)、26(86.7%)、11 26(92.9%)、24(85.7%)、22(78.6%)、20(71.4%)(P<0.05);治疗192周A组新的耐药变异率为0%,B组治疗48周、96周、144周、192周发生耐药变异分别为2例(7.1%)、4例(14.3%)、6例(21.4%)、8例(28.6%)(P<0.05);治疗192周A组HBeAg转阴率为40%,B组为28.6%(P<0.05)。两组均未发现与药物相关的不良反应。结论 ADV联合LAM治疗LAM耐药CHB患者较换用ADV治疗有显著的抗病毒效果,能有效减少新的HBV耐药变异的发生,安全性良好。
