title: Effect of race on outcome following kidney and kidney-pancreas transplantation in type I diabetics: the South-Eastern Organ Procurement Foundation experience.
abstract: In this study we analyze the South-Eastern Organ Procurement Foundation (SEOPF) experience with kidney and kidney-pancreas transplantation in IDDM recipients and evaluate the impact of racial disparity on patient and graft outcome. Data obtained from 4413 kidney-alone and 884 pancreas transplants performed in White and Black type I diabetics at member institutions of SEOPF between 10/1/87 and 7/25/96 were analyzed. Survival data from 15,827 transplants performed during the same period of time in non-diabetics were available for comparison. A lesser proportion of pancreas recipients were Black compared to kidney-alone (12% vs 23%, p < 0.0005). Recipient race had no effect on patient survival in any of the groups studied. Kidney graft survival, on the other hand, was adversely affected by Black race in both non-diabetic and diabetic recipients of a kidney transplant but not in diabetics who received a combined pancreas-kidney transplant. As was the case for patient survival in diabetics, recipient race had no effect on pancreas graft survival. Cox Regression analysis showed that kidney-pancreas transplant (p = 0.034, RR = 0.49) and female recipient gender (p = 0.046, RR = 0.68) were associated with a lower risk of failure of the pancreas graft. The following factors were independent predictors of kidney graft outcome: Donor age (p = 0.0001, RR = 0.95), kidney-pancreas transplant (p = 0.0004, RR = 0.58), AB match (p = 0.001, RR = 0.86), DR match (p = 0.006, RR = 0.82), preservation time (p = 0.012, RR = 1.01), Black recipient race (p = 0.047, RR = 1.23) and living donor (p = 0.06, RR = 0.73). Our findings suggest that the effect of race on graft outcome observed in non-diabetic and, to a lesser extent, diabetic kidney-alone transplant recipients, is not present after kidney-pancreas transplantation.
