恩替卡韦在乙型肝炎慢加急性肝功能衰竭中的应用

目的 观察恩替卡韦治疗对乙型肝炎慢加急性肝功能衰竭患者生存率的影响.方法 84例治疗组乙型肝炎慢加急性肝功能衰竭患者在常规内科治疗基础上加用恩替卡韦0.5 mg/d,99例对照组患者采用常规内科治疗,观察患者存活情况、肝功能生化学指标、HBV DNA定量、PT,比较两组患者在早、中、晚期肝功能衰竭生存率的差异.率的比较采用χ2检验,计数资料采用t检验,生存分析采用Kaplan-Meier方法.结果 在早期慢加急性肝功能衰竭患者中,治疗组存活率为63.3%(31/49例),高于对照组存活率39.7%(23/58例)(χ2=5.923,P=0.015).在中期慢加急性肝功能衰竭患者中,治疗组存活率为63.0%(17/27例),高于对照组存活率35.1%(13/37例)(χ2=4.854,P=0.028).在晚期肝功能衰竭患者中,治疗组8例,存活4例;对照组4例,存活1例.在血清TBiI>342μmol/L的50例患者中,治疗组存活率为56.0%,高于56例对照组的26.8%(χ2=9.351,P=0.002).在治疗4周时,治疗组HBV DNA载量下降3.95 lg拷贝/mL,高于对照组的1.78 lg拷贝/mL(t=5.847,P=0.001).结论 在乙型肝炎慢加急性早期及中期肝功能衰竭患者中,采用恩替卡韦抗病毒治疗能提高生存率,在晚期肝功能衰竭患者中需加大样本量进一步研究.在TBil>342/μmol/L的患者中,恩替卡韦抗病毒治疗能提高患者生存率.

The efficacy of entecavir treatment on acute-on-chronic liver failure in patients with hepatitis B

Objective To evaluate the efficacy of entecavir treatment on hepatitis B patients with acute-on-chronic liver failure. Methods Eighty-four hepatitis B patients with acute-on-chronic liver failure were treated with entecavir 0.5 mg daily and Other routine drugs. Another 99 hepatitis B patients with acute-on-chronic liver failure were treated with only routine drugs as control. The survival, liver functions, hepatitis B virus (HBV) DNA level, prothrombin time (PT) were observed. The survival rates of patients with early, middle or late stage of liver failure were analyzed. The comparison of rates were done using chi-square test. The numeration data were compared by t test. The survival rates were compared using Kaplan-Meier method. Results Among patients with early stage of acute-on-chronic liver failure, the survival rate in treatment group was 63.3% (31/49), which was significantly higher than that in control group (39.7%, 23/58) (χ2=5.923, P=0.015). Among patients with middle stage of acute-on-chronic liver failure, the surviral rate in treatment group was 63.0% (17/27), which was significantly higher than that in control group (35.1%, 13/37) (χ2=4.854, P=0.028). Among patients with late stage of acute-on-chronic liver failure, four out of eight cases survived in treatment group, while one out of four cases survived in control group. In patients with serum total hilirubin (TBil) level > 342 μmol/L, the survival rate was 56.0% in treatment group, which was significantly higher than that in control group (26.8%) (χ2=9.351,P=0.002). At week 4 of the treatment, the HBV DNA reduction in treatment group was 3. 95 lg copy/mL, which was higher than that in control group (1.78 lg copy/mL) (t=5.847, P=0.001). Conclusions Entecavir treatment could improve the survival rate of hepatitis B patients with early or middle stage of acute-on-chronic liver failure. And the further study with larger population is needed in patients with late stage of liver failure. In addition, entecavir therapy could also improve the survival rate of patients with TBil >342 μmol/L.
