摘　　要：目的探讨影响肝移植后糖尿病(posttransplantation diabetes mellitus,PTDM)发生的相关危险因素,并分析PTDM对预后的影响。方法选取2015年1月至2020年9月于南京医科大学第一附属医院肝胆中心行公民逝世后器官捐献(donation after citizen’s death,DCD)肝移植术患者,将患者分为PTDM组与非PTDM组,比较两组患者的基线特征、术中信息及术后并发症情况,采用竞争风险模型识别影响PTDM发生的相关危险因素,采用Cox回归分析PTDM对患者预后的影响。结果肝移植术后1、3、5年糖尿病的发病率分别为13.3%、16.9%、27.0%。2组间患者年龄、术后住院时长、免疫排斥反应差异有统计学意义。考虑死亡为竞争风险事件后,年龄每增加10岁,发生PTDM的风险增加45%(SHR=1.45,95%CI=1.17~1.80);有免疫排斥反应患者PTDM的发病风险是无免疫排斥反应患者的2.06倍(95%CI=1.00~4.24);术后住院超过1个月患者PTDM的发病风险增加62%(SHR=1.62,95%CI=1.01~2.59)。PTDM患者发生晚期感染并发症的风险为非PTDM患者的2.48倍(95%CI=1.22~5.04),而两组患者晚期胆道并发症的发生率无统计学差异(RR=1.58,95%CI=0.77~3.26)。控制疾病诊断后,PTDM组患者死亡风险是非PTDM患者的1.73倍(95%CI=1.07~2.77)。结论PTDM发病率与患者年龄、免疫排斥反应、术后住院时长相关,且PTDM患者总体生存较差,术后晚期感染风险上升。移植术后应早期筛查血糖,防治PTDM,以期减少PTDM的发生,改善患者预后。Objective To investigate the associated risk factors affecting the development of posttransplantation diabetes mellitus(PTDM)and to analyze the effect of PTDM on patient outcomes.Methods We selected patients who underwent liver transplantation from DCD donors at the hepatobiliary center of the First Affiliated Hospital of Nanjing Medical University between January 2015 and September 2020.The patients were divided into PTDM and non PTDM groups,and the baseline characteristics,intraoperative information and postoperative complications were compared between the two groups.A competing risk model was used to identify relevant risk factors affecting the occurrence of PTDM,and Cox regression was used to analyze the effect of PTDM on patient outcomes.Results The incidence of diabetes at 1,3 and 5 years after liver transplantation was 13.3%,16.9%,27.0%,respectively.There were statistically significant differences in patient age,length of postoperative hospital stay,and immune rejection between groups.After accounting for death as a competing risk event,every 10-year increase in age was associated with a 45%increased risk of developing PTDM(SHR=1.45,95%CI=1.17~1.80);The risk of PTDM in patients with immune rejection was 2.06 times higher than that in patients without immune rejection(95%CI=1.00~4.24);Patients hospitalized for more than one month postoperatively had a 62%increased risk of developing PTDM(SHR=1.62,95%CI=1.01~2.59).The risk of late infectious complications in PTDM patients was 2.48 times higher than non PTDM patients(95%CI=1.22~5.04);Whereas the incidence of late biliary complications was not statistically different between the two groups(RR=1.58,95%CI=0.77~3.26).After controlling for disease diagnosis,patients in the PTDM group had a 1.73-fold(95%CI=1.07~2.77)higher risk of death than non PTDM patients.Conclusion The incidence of PTDM is associated with patient age,immune rejection,and long postoperative hospitalization,and the overall survival of PTDM patients is poor,with a rising risk of late postoperativ
