摘要: 目的 分析聚乙二醇干扰素(PEG-IFNα-2a)联合阿德福韦酯(ADV)治疗HBeAg阳性慢性乙型肝炎(CHB)患者48 w时的疗效及其预测因素。方法 将196例HBeAg阳性CHB患者分为PEG-IFNα-2a治疗64例,ADV治疗66例和PEG-IFNα-2a联合ADV治疗66例,疗程均为48 w。采用ELISA法检测INF-γ和IL-10;采用Achitect(Abbott)微粒子化学发光免疫分析法检测HBeAg定量。结果 在治疗48 w时,联合组HBV DNA阴转率、HBeAg阴转率、HBeAg转换率和ALT复常率分别为74.2%、24.2%、48.5%和80.3%,显著高于干扰素组(53.1%、10.9%、29.7%和54.7%,P<0.05)和阿德福韦组(62.1%、13.6%、9.1%和65.2%,P<0.05);联合组INF-γ水平为(45.3±11.3) pg/ml,显著高于干扰素组[(37.1±10.3) pg/ml,P<0.05]和阿德福韦组[(36.3±11.5) pg/ml,P<0.05];联合组IL-10水平为(10.3±14.6) pg/ml,显著低于干扰素组[(17.1±11.3) pg/ml,P<0.05]和阿德福韦组[(18.3±10.5) pg/ml,P<0.05];联合组治疗48 w时HBeAg血清学转换与治疗24 w时HBeAg水平下降的百分比有关,即治疗24 w时HBeAg水平较基线下降大于89.1%的阳性预测值为88.7%,阴性预测值(NPV)为81.9%,灵敏度为83.1%,特异度为87.9%。结论 PEG-IFNα-2a联合ADV治疗HBeAg阳性慢性乙型肝炎能增强机体细胞免疫应答,疗效优于单药治疗,其中治疗24 w时HBeAg下降的百分比可预测48 w时的疗效。

Abstract: Obiective To analyze the efficacy and the predictive factors of peginterferon α-2a (PEG-IFNα-2a) and adefovir dipivoxil (ADV) combination therapy in patients with HBeAg-positive chronic hepatitis B (CHB). Methods 196 CHB patients positive for HBeAg were divided into PEG-IFNα-2a monotherapy group (n=64),ADV monotherapy group(n=66),and PEG-IFNα-2a plus ADV combination therapy group (n=66). All patients were treated for 48 weeks. Serum INF-γ and IL-10 levels were detected by ELISA. Results At the end of 48 weeks,the serum HBV DNA loss,HBeAg negative,HBeAg seroconversion and ALT normalization rates in PEG-IFNα-2a plus ADV group(74.2%,24.2%,48.5% and 80.3%) were significantly higher than in ADV group (62.1%,13.6%,9.1% and 65.2%,P<0.05) and in PEG-IFNα-2a group(53.1%,10.9%,29.7% and 54.7%,P<0.05); Serum INF-γ levels in combined treatment group [(45.3±11.3) pg/ml] were significantly higher than in ADV group [(36.3±11.5) pg/ml,P<0.05] and in PEG-IFNα-2a group [(37.1±10.3) pg/ml,P<0.05];Serum IL-10 levels in combined treatment group [(10.3±14.6) pg/ml] were significantly lower than in ADV group [(18.3±10.5) pg/ml,P<0.05] and in PEG-IFNα-2a group [(17.1±11.3) pg/ml,P<0.05];Serum HBeAg seroconversion rate in combined treatment group at the end of 48 weeks was associated with the negative rate of HBeAg at 24 weeks,e.g. greater than 89.1% reduction of serum HBeAg levels at 24 weeks than baseline had a positive predictive value of 88.7%,negative predictive value of 81.9%,sensitivity of 83.1% and specificity of 87.9%. Conclusion The efficacy of pegylated interferon α-2a combination with adefovir dipivoxil therapy is superior to monotherapy of either of them in HBeAg-positive chronic hepatitis B patients and the reduction of HBeAg levels at 24 weeks could predict the efficacy of 48 weeks.
