High mortality in orthotopic liver transplant recipients who require hemodialysis.
CLINICAL TRANSPLANTATION(2011)
摘要
Acute renal failure is a significant risk factor for death in patients with liver failure. The goal of this study was to analyze the impact of peri-transplant dialysis on the long-term mortality of liver transplant recipients. We performed a single-center, retrospective cohort study of 743 adult liver transplants; patients who received first liver transplants were divided into four groups: those who received more than one dialysis treatment (hemodialysis [HD], continuous veno-venous hemodialysis [CVVH]) pre-orthotopic liver transplantation (OLT), post OLT, pre- and post OLT, and those not dialyzed. There was no statistically significant difference in the mean survival time for patients who were not dialyzed or dialyzed only pre-OLT. Mean survival times were markedly reduced in patients dialyzed post OLT or both pre- and post OLT compared with those never dialyzed. Mortality risk in a Cox proportional hazards model correlated with hemodialysis post OLT, intra-operative vasopressin or neosynephrine, donor age > 50 yr, Cr > 1.5 mg/dL at transplant, and need for subsequent retransplant. Risk of post-OLT dialysis was correlated with pre-OLT dialysis, intra-operative levophed, pre-OLT diabetes, African American race, pre-OLT Cr > 1.5, and male gender. We conclude that renal failure requiring hemodialysis post liver transplant, irrespective of pre-transplant dialysis status, is a profound risk factor for death in liver transplant recipients.
