BACKGROUND: Simultaneous pancreas-kidney transplantation (SPK) transplantation has become an accepted therapy for type 1 diabetic patients with end-stage renal disease. This open-label, multicenter study compared the efficacy and safety of tacrolimus with the microemulsion (ME) formulation of cyclosporine in a clinical setting. The 1-year results are reported here. METHODS: The study was conducted in 10 European centers and one center in Israel. One hundred three patients were randomly assigned to tacrolimus and 102 to cyclosporine-ME. All patients received concomitant rabbit anti-T-cell globulin induction therapy, mycophenolate mofetil (MMF), and short-term cortico-steroids. The initial daily oral doses were 0.2 mg/kg for tacrolimus, 7 mg/kg for cyclosporine-ME, and 2 to 3 g for MMF. RESULTS: The 1-year incidence of biopsy-proven kidney or pancreas acute rejection was lower with tacrolimus (27.2%) than with cyclosporine-ME (38.2%; P = 0.09). Pancreas graft survival at 1 year was 91.3% with tacrolimus and 74.5% with cyclosporine-ME (P <0.0005). Renal graft survival was similar in the two study groups. There were no significant treatment-related differences in pancreatic or renal graft function. In total, 34 patients switched treatment from cyclosporine-ME to tacrolimus, but only 6 patients receiving tacrolimus required alternative therapy. Mean doses of MMF at 1 year were also lower in the tacrolimus group (1.36 vs. 1.67 g/day; P = 0.007). CONCLUSION: These findings support the use of tacrolimus therapy for uremic patients with type 1 diabetes who are undergoing SPK transplantation.
