Abstract:

目的 探讨替比夫定治疗乙肝e抗原(HBeAg)阳性慢性乙型肝炎(CHB)患者72周的疗效及预测因素的分析。方法 选择2007年9月-2012年9月符合入选标准的82例CHB患者接受替比夫定治疗72周,于治疗前基线、治疗后每3个月查丙氨酸氨基转移酶(ALT)、乙肝病毒DNA(HBVDNA)、乙肝病毒血清标志物,观察治疗期间累计生化学应答率、完全病毒学应答率(CVR)、HBeAg血清学转换率(SR)及耐药率,分析基线ALT水平分为<5ULN(正常值检测下限)组及≥5ULN组、HBVDNA水平(分为<107copies/mL组及≥107copies/mL组)、24周HBVDNA水平(<3log10copies/mL组及≥3log10copies/mL组),预测72周CVR及SR。结果 172周累计生化学应答率、CVR、SR、耐药率分别为86.6%、81.7%、42.7%、18.2%;2基线ALT≥5ULN对72周SR有预测价值(χ2=5.651,P=0.017),HBVDNA<107copies/mL对CVR有预测价值(χ2=7.083,P=0.008);324周HBVDNA<103copies/mL对72周CVR及SR均有预测价值(χ2=27.339,5.131;P=0.000,0.023)。结论 替比夫定初治HBeAg阳性CHB患者疗效及安全性好,治疗24周HBVDNA<103copies/mL是72周疗效的最佳预测指标。
