Long-term outcome after pancreas transplantation

Purpose of review: Pancreas transplantation provides the only proven method to restore long-term normoglycemia in patients with insulin-dependent diabetes mellitus. Although many studies describe the very important risk factors for short-term survival of a pancreas transplant, there is not a lot of information available about factors that distinguish short-term from long-term graft function. Recent findings: The analysis of 18159 pancreas transplants from the International Pancreas Transplant Registry, performed from 25 July 1978 to 31 December 2005, showed an improvement not only in short-term but also in long-term graft function. Most recent 5-year, 10-year and 20-year graft function for transplants with the appropriate follow-up time showed 80, 68 and 45%, respectively, for simultaneous pancreas/kidney transplants; 62, 46 and 16%, respectively, for pancreas after kidney; and 59, 39 and 12%, respectively, for pancreas transplants alone. Important factors influencing long-term function were factors that described the quality of the deceased donor. Pancreas transplants in younger or African-American recipients showed a higher risk of graft failure. Anti-T-cell induction therapy had a significant impact on long-term survival in solitary transplants. Summary: With a careful donor selection, not only short-term but also long-term pancreas graft function and, therefore, good metabolic control can be achieved for the diabetic patient.
