Abstract
Background: Pancreas transplantation offers excellent outcomes today in patients who have type-1 diabetes mellitus (DM) with difficult control in terms of increasing patient and pancreatic graft survival. Different factors in donors, recipients, and the perioperative period have been associated with long-term graft survival. The aim of this study was to compare pancreatic graft survival in simultaneous pancreas-kidney transplantation (SPK) and the other two modalities, pancreas-alone and pancreas-after-kidney transplantation (non-SPK), at our institution.
Methods: This retrospective cohort study included 63 pancreas transplantation patients from January 2007 to May 2012 at our institution. The patients were divided into two groups: SPK and non-SPK transplantations. We excluded those patients who had transplants with vascular graft loss. The primary endpoint was 1-year and overall graft survival with consideration of multiple relevant variables. Non-parametric tests were calculated with the statistical package SPSS 20 (SPSS INC, Chicago, IL).
Results: The 1-year and overall graft survival in this period was 87.3% and 82.5%, respectively. The median follow-up was 963 days. The causes of graft loss were vascular (64%) and immunologic (34%). Finally, we included 56 pancreas transplantations, 46 (82%) were SPK and 10 (18%) non-SPK. The donor and recipient characteristics were similar in both groups, except for the duration of DM (SPK 22 years vs. non-SPK 29 years) and recipient body mass index (SPK 23 vs. non-SPK 28); P = .042 and P = .003, respectively. The cold ischemia time was 563 minutes (standard deviation, 145). Bivariate analysis showed that long-term graft loss was only influenced by matching for gender (P = .023). Using the Kaplan-Meier method, the pancreas graft survival was better in SPK than in non-SPK transplants (log rank .038).
Conclusions: Patients who receive pancreas-alone or pancreas-after-kidney grafts have shorter long-term graft survival. Multiple strategies should be applied to improve immunologic surveillance and obtain an early diagnosis of graft rejection.
