We have investigated the metabolic effects of segmental (neoprene-injected) pancreas transplantation versus whole (enteric-diverted) pancreas transplantation. Seventeen uremic insulin-dependent diabetes mellitus (IDDM) patients received a simultaneous pancreaticorenal transplant: in a prospective, randomized study, 9 patients received a segmental neoprene-injected graft (group A) while 8 patients received a total pancreatico-duodenal graft, with enteric diversion (group B). The immunosuppressive therapy was based on ALG, CsA, azathioprine, and steroids. Three months after surgery, patients were submitted to the following metabolic investigation: i.v. and oral glucose tolerance tests, Hba 1, i.v. arginine test, and a 24-hr metabolic profile. The OGTT, HbA1, and metabolic profile were repeated 12 and 24 months after transplantation. At 3 months after transplantation, the OGTT showed delayed insulin secretion and higher blood glucose levels in group A. Serum insulin levels after IVGTT or arginine were higher in group B than in group A. OGTT at 12 and 24 months were unchanged in group B, while in group A a higher incidence of impaired glucose tolerance (IGT) and diabetes mellitus response were observed. HbA1 and blood glucose levels during the 24-hr profile showed good metabolic control in both groups at 3, 12, and 24 months. We can conclude that both the segmental and total pancreas transplantation restore a good metabolic control in IDDM patients, though a higher incidence of IGT and DM responses were observed after OGTT in the patients receiving a segmental graft. These abnormalities do not seem to interfere with metabolic control in everyday life. These results seem to be the consequence of the different B cell masses transplanted with these two techniques. |
