摘　　要：目的比较2型糖尿病(T2DM)合并终末期肾病(ESRD)患者行同期胰肾联合移植(SPKT)或尸体肾移植(DDKT)后的移植肾及患者生存情况,并分析SPKT术后影响患者存活的危险因素。方法获取美国器官资源共享网络(UNOS)数据库中2003年1月27日-2021年1月1日接受肾脏移植患者的临床及预后资料。根据纳入、排除标准最终纳入50230例,其中DDKT组48669例,SPKT组1561例。采用Kaplan-Meier法比较两组受者的移植肾及患者存活情况,并通过倾向性评分匹配(PSM)均衡组间混杂因素。采用Cox回归模型分析SPKT术后影响患者生存的独立危险因素。结果与DDKT组比较,SPKT组受者的中位年龄小(P<0.001)、男性占比高(P<0.001)、BMI低(P<0.001)、透析时间和移植等待时间短(P<0.001)、私人医保占比高(P<0.001)、既往移植占比低(P<0.001)、糖尿病确诊年龄低(P<0.001)、外周血管病史少(P=0.033);与DDKT组比较,SPKT组供者的中位年龄小(P<0.001)、男性占比高(P<0.001)、BMI低(P<0.001)、高血压病史和糖尿病史少见(P<0.001);在移植相关因素上,与DDKT组比较,SPKT组的供肾冷缺血时间短(P<0.001)、HLA错配程度高(P<0.001)、KDPI低(P<0.001)。与DDKT组比较,SPKT组出院时血肌酐水平低(P<0.001)、术后移植肾功能恢复延迟(DGF)发生率和AR发生率低(P<0.001),住院时间长(P<0.001)。原始和PSM后的Kaplan-Meier生存分析曲线均显示SPKT组的移植肾和患者存活率明显高于DDKT组(P<0.001)。Cox回归模型分析显示,受者年龄、受者种族、供者年龄和供肾冷缺血时间是影响SPKT术后患者存活的独立危险因素(P<0.05)。结论T2DM合并ESRD患者行SPKT较DDKT的远期移植肾和患者存活率高。受者年龄、受者种族、供者年龄和供肾冷缺血时间是影响SPKT术后患者存活的独立危险因素。Objective To compare the outcomes of transplant kidneys and patient survival between simultaneous pancreas-kidney transplantation(SPKT)recipients and deceased donor kidney transplant(DDKT)recipients in patients with type 2 diabetes mellitus(T2DM)complicated with end-stage renal disease(ESRD),and to analyze the risk factors affecting patient survival post�SPKT.Methods Clinical and prognostic data of patients who underwent kidney transplantation from January 27,2003,to January 1,2021,were retrieved from the United Network for Organ Sharing(UNOS)database.A total of 50230 cases were selected based on inclusion criteria,with 48669 cases in DDKT group and 1561 cases in SPKT group.Kaplan-Meier analysis was employed to compare transplant kidney and patient survival between the two groups,and propensity score matching(PSM)was utilized to balance confounding factors between the groups.Cox regression model was used to analyze independent risk factors affecting patient survival post-SPKT.Results Compared with DDKT group,recipients in SPKT group had a younger median age(P<0.001),a higher proportion of males(P<0.001),lower BMI(P<0.001),shorter dialysis and transplant waiting times(P<0.001),a higher percentage of private medical insurance(P<0.001),a lower proportion of previous transplants(P<0.001),a younger age at diabetes diagnosis(P<0.001),and a lower incidence of peripheral vascular disease(P=0.033).Compared with DDKT group,the donors in SPKT group had a younger median age(P<0.001),a higher proportion of males(P<0.001),lower BMI(P<0.001),and a lower prevalence of hypertension and diabetes history(P<0.001).In terms of transplant-related factors,the SPKT group had a shorter donor kidney cold ischemia time(P<0.001),a higher degree of HLA mismatch(P<0.001),and a lower Kidney Donor Profile Index(KDPI)(P<0.001)when compared with DDKT group.The SPKT group had lower serum creatinine levels at discharge(P<0.001),lower rates of postoperative delayed graft function(DGF)and acute rejection(AR)(P<0.001),but longer hospital stays(P<0.0
