title: Cardiovascular benefits of simultaneous pancreas-kidney transplant versus kidney alone transplant in diabetic patients.
abstract: The aim of our study was to demonstrate the cardiovascular benefits of simultaneous pancreas-kidney transplantation when compared to kidney-alone transplants in diabetic recipients.
  
  
  METHODS
  A total of 386 renal transplants were performed from 1985 to 2004, including 262 (68%) in diabetic recipients and 124 (32%) in nondiabetics. Among the former group, 200 kidneys were transplanted simultaneously to the pancreatic graft (KP group) and 62 were kidney-alone transplants (KA group). The mean time on dialysis was 31 +/- 20 months (range 0-126 months). The duration of diabetes was 24 +/- 7 years (range 5-51 years). Ninety-nine percent of the patients were on renal replacement therapy (79% on hemodialysis and 20% on peritoneal dialysis).
  
  
  RESULTS
  Among 262 patients, 28 (11%) died due to a cardiovascular event, which was higher among KA patients compared with the KP group (P = .004). Overall patient survival was significantly higher in the KP group when compared with the KA group (log-rank: P = .0004). Patient survivals were 80% and 70% versus 70% and 40% at 5 and 10 years in the KP and KA groups, respectively. Kidney graft survivals were 81% and 60% versus 63% and 26% at 5 and 10 years in the KP and KA groups, respectively. Pancreas graft survival was 70% and 50% at 5 and 10 years, respectively.
  
  
  CONCLUSIONS
  This clinical evaluation, even if retrospective, confirmed that simultaneous pancreas-kidney transplantation has a protective effect against cardiovascular mortality in diabetic recipients affected by end-stage renal disease.
