阿德福韦酯联合苦参素治疗拉米夫定耐药慢性乙肝的研究

【摘要】目的:观察阿德福韦酯联合苦参素治疗拉米夫定耐药慢性乙型肝炎的的疗效。方法:将入选病例随机分为阿德福韦酯组和联合治疗组,阿德福韦酯组给予阿德福韦酯10 mg/d,连用48周。联合治疗组在阿德福韦酯组治疗基础上加用苦参素0.6 mg,静脉滴注,1次/日,连用48周。观察两组病毒应答率、生化应答率、HBeAg阴转及HBe转换率。结果:阿德福韦酯组24周时病毒应答率53%,生化应答率53%,HBeAg阴转率15%,HBe转换率6%。48周时病毒应答率59%,生化应答率68%,HBeAg阴转率26%,HBe转换率12%。联合治疗组24周时病毒应答率68%,生化应答率74%,HBeAg阴转率38%,HBe转换率21%,48周时病毒应答率85%,生化应答率91%,HBeAg阴转率56%,HBe转换率38%。结论:阿德福韦酯治疗对拉米夫定耐药的慢性乙型肝炎效果显著,且随时间延长而疗效提高。与苦参素联合,其疗效更加显著。

【Abstract】Objective:To explore the effects of adefovir dipivoxil combined with kushensuin lamivudine-resistant patients with chronic hepatitis B. Methods:All selected cases of chronic hepatitis B were divided into two groups,adefovir dipivoxil treatment group and combination treatment group. In adefovir dipivoxil treatment group,adefovir dipivoxil was given 10 mg one time a day for 48 weeks. In combination treatment groupe,adefovir dipivoxil was given as the same, but kushensu was given 0.6 mg intravenous drip one time a day for 48 weeks. At the end of the therapy,the rates of viral response,chemical response,HBeAg negative and anti-HBe transformation were detected. Results:After 24 weeks of therapy,in adefovir dipivoxil treatment group and combination treatment group,the rates of viral response, chemical response,HBeAg negative and anti-HBe transformation was 53%,53%,15%,6% and 59%,68%,26%,12% respectively.And after 48 weeks of therapy,the rates of viral response,chemical response,HBeAg negative and anti-HBe transformation was 68%,74%,38%,21% and 85%,91%,56%,38% respectively. Conclusion:Adefovir dipivoxil is an effective treatment method for lamivudine-resistant patients with chronic hepatitis B, and the effect would be more significant by treating more long time. Also,the effect would be more significant when combination with kushensu.

自1998年拉米夫定治疗慢性乙型肝炎以来,出现对拉米夫定耐药的病例逐渐增多,为此,我院于2006年9开始应用阿德福韦酯联合苦参素治疗拉米夫定耐药的HBeAg阳性慢性乙型肝炎,现报道如下:

1 资料与方法

1.1 临床资料:68例均为我院门诊或住院患者,入选标准:(1)符合2000年《病毒肝炎防治方案》中病毒性肝炎诊断标准[1]。(2)HBsAg(+)、HBeAg(+)、HBV DNA>105拷贝/ml。(3)治疗前ALT >正常值2倍。(4)应用拉米夫定治疗1年以上无明显疗效(HBVDNA下降

1.2 根据1∶1的比例随机分为阿德福韦酯组和联合治疗组,其中阿德福韦酯组34例,男21例,女13例,年龄(29.8±12.6)岁。联合治疗组34例,男19例,女15例,年龄(33.2±10.6)岁。两组间人口学特征及临床特征经统计学处理,差异无显著性(P>0.05),具有可比性。

1.3 治疗方法:阿德福韦酯组给予阿德福韦酯10 mg,每日1次,共48周。联合治疗组在阿德福韦酯组治疗的基础上,加用苦参素0.6 mg,静脉滴注,每日1次,连用48周。

1.4 观察项目:两组治疗前、治疗后24周、48周时肝功、肾功、HBV DNA、乙肝5项指标。

1.5 统计学方法:两组率的比较采用χ2检验。

3 讨论

3.1 拉米夫定治疗慢性乙型肝炎取得了明显疗效,通过抑制HBV复制,使血清ALT恢复正常,改善肝脏炎症活动,延缓纤维化的进展[2~4]。但长期应用后易出现病毒变异和临床抗药性,治疗1年后发生临床耐药的比率可达70%或更高,且某些拉米夫定耐药者可发生重型肝炎和肝病进展[5,6]。

3.2 阿德福韦酯是新一代核苷类似物,是活性成份阿德福韦的前体药物,口服后在体内迅速转化为阿德福韦,体内外试验显示,阿德福韦可有效抑制HBV复制,不仅对野生株有良好的抑制作用,对YMDD变异株也有明显抑制作用[7,8]。而苦参素有提高免疫力的功能,特别是增加细胞免疫的功能。它使淋巴细胞增殖,使幼稚淋巴细胞成熟,变为有免疫功能的淋巴细胞。能连续诱导T细胞分化发育的各个阶段,增强成熟T细胞对抗原或其他刺激的反应,促进T细胞产生各种细胞因子,如IFN、INF等。

3.3 阿德福韦酯10 mg/d对拉米夫定耐药HBeAg阳性慢性乙型肝炎患者治疗24周时,病毒应答率为53%,生化应答率为53%,HBeAg阴转率为15%,HBe转换率为6%,表明阿德福韦酯对拉米夫定耐药HBeAg阳性慢性乙型肝炎有显著疗效。而48周时,病毒应答率为59%,生化应答率为68%,HBeAg阴转率为26%,HBeAg转换率为12%,表明阿德福韦酯对拉米夫定耐药HBeAg慢性乙型肝炎的治疗,随时间延长而疗效提高。在阿德福韦酯联合苦参素治疗组中,24周时,拉米夫定耐药的HBeAg阳性慢性乙型肝炎病毒应答率为68%,生化应答率为74%,HBeAg阴转率为38%,HBe转换率为21%,均较单用阿德福韦酯为高,特别是HBeAg阴转及HBe转换差别较大,但经统计学处理无显著意义,可能与例数较少有关。而48周其病毒应答率为85%,生化应答率为91%,HBeAg阴转率56%,HBe转换率为38%,与单用阿德福韦酯组比较差异均有显著性(P
