Brief Summary

Under chronic immunosuppressive and corticosteroid therapy, transplant patients have a tendency to develop in the long-term diabetes. Patients who have received extra pancreatic tissue with their liver and small bowel transplantation have not yet developed insulin resistance or diabetes mellitus. We would like to investigate to which level insulin secretory capacity the extra pancreas together with the native pancreas has in these transplant patients using the hyperglycemic clamp. These data will be compared with the data obtained from healthy controls.

Outcome Measures

Primary Outcomes (1)

  • Change in the stimulated serum C-peptide leveS (mean area under the curve [AUC] after hypercemic clamp test

    1. Sampling before glucose infusion (-30 to 0 minutes) 2. Glucose infusion (0 to 14 minutes) \- increase of glycemia acutely to 180 mg/dL in approx. 14 min. 3. Clamping at glycemia of 180 mg/dL (15 to 150 minutes) * maintain glycemia at 180 mg/dL till 150 min. after start glucose infusion * blood sample for measurement of glycemia, proinsulinemia and C-peptide at 120, 135 and 150 minutes (n= 3x5 ml) for evaluation of second-phase insulin release 4. Intravenous injection of 1 mg glucagon (150 to 170 minutes)
