      目的  分析自身免疫性肝病(AILD)与病毒性肝炎肝硬化肝移植的预后差异及预后影响因素。
      方法  回顾性分析2002年1月至2017年1月行肝移植的75例受者临床资料。将受者分为AILD组(25例)和病毒性肝炎肝硬化组(50例)。观察受者的术中情况，包括器官热缺血时间、冷缺血时间、手术时间、无肝期、输血量; 观察术后并发症发生情况，包括重度急性肾损伤(AKI)、感染、急性排斥反应、胆道相关并发症、血管相关并发症、移植后糖尿病(PTDM); 观察出院后随访情况。分析肝移植受者预后的影响因素。
      结果  AILD组与病毒性肝炎肝硬化组的器官热缺血时间、冷缺血时间、手术时间、无肝期比较，差异均无统计学意义(均为P > 0.05)。AILD组受者术后急性排斥发生率高于病毒性肝炎肝硬化组受者(P < 0.05)，术后重度AKI发生率低于病毒性肝炎肝硬化组受者(P < 0.05)。AILD组术后1、3、5年生存率分别为92%、87%、87%，病毒性肝炎肝硬化组术后1、3、5年生存率88%、88%、88%，两组受者累积生存率的差异均无统计学意义(均为P > 0.05)。单因素分析结果显示年龄、终末期肝病模型(MELD)评分、重度AKI、感染、胆道相关并发症等5个指标是受者预后的影响因素(均为P < 0.05)。
      结论  AILD组和病毒性肝炎肝硬化组受者移植术后总体生存预后无明显差异，年龄、MELD评分、重度AKI、感染、胆道相关并发症是影响肝移植预后风险因素。

     

    Abstract:
      Objective  To analyze the difference and influential factors of clinical prognosis between liver transplantation with autoimmune liver disease (AILD) and viral hepatitis cirrhosis.
      Methods  Clinical data of 75 recipients undergoing liver transplantation from January 2002 to January 2017 were retrospectively analyzed. All recipients were divided into the AILD group (n=25) and viral hepatitis cirrhosis group (n=50). The intraoperative conditions of the recipients were observed including warm ischemia time, cold ischemia time, operation time, anhepatic phase and blood transfusion volume. Postoperative complications were observed including severe acute kidney injury (AKI), infection, acute rejection, biliary tract-related complications, vascular-related complications and post transplantation diabetes mellitus (PTDM). The follow-up status were monitored after discharge. The prognostic factors of liver transplant recipients were analyzed.
      Results  The warm ischemia time, cold ischemia time, operation time and anhepatic phase did not significantly differ between two groups (all P > 0.05). In the AILD group, the incidence of postoperative acute rejection was remarkably higher, whereas the incidence of postoperative severe AKI was significantly lower than those in the viral hepatitis cirrhosis group (both P < 0.05). The postoperative 1-, 3- and 5-year survival rates in the AILD group was 92%, 87%, and 87%, which did not significantly differ from 88%, 88% and 88% in the viral hepatitis cirrhosis group (all P > 0.05). Univariate analysis showed that age, model for end-stage liver disease (MELD) score, severe AKI, infection and biliary tract-related complications were the influencing factors of clinical prognosis of the recipients (all P < 0.05).
      Conclusions  The overall survival prognosis does not significantly differ between the AILD and viral hepatitis cirrhosis groups. Age, MELD score, severe AKI, infection and biliary tract-related complications are the risk factors affecting the clinical prognosis of liver transplantation recipients.
