In this retrospective study of hepatitis C virus (HCV)-infected transplant recipients in the 9-center Adult to Adult Living Donor Liver Transplantation Cohort Study, graft and patient survival and the development of advanced fibrosis were compared among 181 living donor liver transplant (LDLT) recipients and 94 deceased donor liver transplant (DDLT) recipients. Overall 3-year graft and patient survival were 68% and 74% in LDLT, and 80% and 82% in DDLT, respectively. Graft survival, but not patient survival, was significantly lower for LDLT compared to DDLT (P = 0.04 and P = 0.20, respectively). Further analyses demonstrated lower graft and patient survival among the first 20 LDLT cases at each center (LDLT <or=20) compared to later cases (LDLT > 20; P = 0.002 and P = 0.002, respectively) and DDLT recipients (P < 0.001 and P = 0.008, respectively). Graft and patient survival in LDLT >20 and DDLT were not significantly different (P = 0.66 and P = 0.74, respectively). Overall, 3-year graft survival for DDLT, LDLT >20, and LDLT <or=20 were 80%, 79% and 55%, with similar results conditional on survival to 90 days (84%, 87% and 68%, respectively). Predictors of graft loss beyond 90 days included LDLT <or=20 vs. DDLT (hazard ratio [HR] = 2.1, P = 0.04), pretransplant hepatocellular carcinoma (HCC) (HR = 2.21, P = 0.03) and model for end-stage liver disease (MELD) at transplantation (HR = 1.24, P = 0.04). In conclusion, 3-year graft and patient survival in HCV-infected recipients of DDLT and LDLT >20 were not significantly different. Important predictors of graft loss in HCV-infected patients were limited LDLT experience, pretransplant HCC, and higher MELD at transplantation.
在这项针对9个中心成人对成人活体肝移植队列研究中丙型肝炎病毒(HCV)感染的移植受者的回顾性研究中,比较了181例活体肝移植(LDLT)受者和94例尸体肝移植(DDLT)受者的移植物和患者生存率以及晚期纤维化的发生情况。总体而言,LDLT组3年移植物和患者生存率分别为68%和74%,DDLT组分别为80%和82%。与DDLT相比,LDLT的移植物生存率显著较低,但患者生存率无显著差异(P分别为0.04和0.20)。进一步分析表明,各中心前20例LDLT病例(LDLT≤20)的移植物和患者生存率低于后序病例(LDLT>20;P分别为0.002和0.002)以及DDLT受者(P分别<0.001和0.008)。LDLT>20组和DDLT组的移植物和患者生存率无显著差异(P分别为0.66和0.74)。总体而言,DDLT、LDLT>20和LDLT≤20组的3年移植物生存率分别为80%、79%和55%,以存活至90天为条件的结果相似(分别为84%、87%和68%)。90天后移植物丢失的预测因素包括LDLT≤20与DDLT(风险比[HR]=2.1,P=0.04)、移植前肝细胞癌(HCC)(HR=2.21,P=0.03)以及移植时终末期肝病模型(MELD)(HR=1.24,P=0.04)。总之,HCV感染的DDLT受者和LDLT>20受者的3年移植物和患者生存率无显著差异。HCV感染患者移植物丢失的重要预测因素是LDLT经验有限、移植前HCC以及移植时较高的MELD。
