Long-term follow-up of 78 simultaneous pancreas-kidney transplants at a single-center institution in Europe

Background. The objective of this study was to determine the long-term results after simultaneous pancreas-kidney transplantation (SPK) at a single-center institution in Europe. Patients and Methods. Seventy-eight consecutive patients with insulin-dependent diabetes mellitus and end-stage nephropathy were followed for a median of 7 years after SPK. Inummosuppressive protocol consisted of cyclosporine A, azathioprine, prednisone, and antithymocyte globulin. Multivariate Cox proportional hazard model was used to investigate the impact of different putative risk factors on long-term patient survival. Health-related quality of life was assessed by a validated questionnaire (SF-36). Results. Patient survival at 5 and 10 years was 81% and 67%, respectively. Pancreas function rate was 73% and 60% and kidney function 67% and 44%, respectively. In multivariate analysis, preexisting myocardial infarction (relative risk [RR] 5.1, 95% confidence interval [CI] 1.5-16.6) and amputation (RR 3.7, 95% CI 1.1-12.9) were strongly associated with a diminished long-term patient survival. Analysis of patients with long-term functioning pancreas and kidney grafts revealed excellent results for quality of life posttransplant that were comparable with average scores of the normal German population. Conclusions. This series representing the largest experience with long-term follow-up in Europe confirms an excellent long-term survival and an exceptional quality of life after SPK.
