[Combined pancreas and kidney transplantation for IDDM patients with diabetic renal failure].

We performed 7 cases of pancreas transplantation (PTX), simultaneous pancreas and kidney transplantation in 4 cases, and PTX after kidney transplantation in 3 cases. The pancreas and kidney were extirpated after in situ perfusion using UW solution and stored in UW solution. The pancreas was transplanted in the left iliac fossa with bladder drainage, and the kidney was placed in the contralateral iliac fossa. The immunosuppressive regimen consisted of cyclosporine, methylprednisolone, azathioprine and antilymphocyte globulin. Gabexate mesilate (30-40 mg/kg/day) and PGE1 (5 ng/kg/min) was administered intravenously to prevent the vascular thrombosis. The original diseases of 7 patients were insulin-dependent diabetes mellitus (IDDM) with chronic renal failure, retinopathy and neuropathy. Six out of 7 patients became insulin-free after PTX, while one patient developed the vascular thrombosis in the pancreatic graft which was removed after 12 hours after the transplantation. All patients became dialysis-free and serum creatinine was ranging from 1.5 to 2.0 mg/dl. HbAlc remained within normal range in 6 out of 7 patients, who showed normal to borderline glucose tolerance in 75g oral glucose tolerance test. Although further investigation will be required, PTX from cardiac-arrest donor will be promising as one of the therapeutic modalities for IDDM patients.
