Abstract
PURPOSE: We wanted to compare glycemic control post pancreas transplantation with newer therapeutic options. METHODS: We conducted a retrospective analysis of pancreas transplantation at our institution from January 1, 2008, through September 30, 2021. All patients who underwent pancreatic transplantation were 18 years and older. We compared pre-transplant glycemic control of those patients, whether self-monitoring or continuous glucose monitor to their post-transplant glycemic control. Outcomes were assessed by HgbA1C level at evaluation (eval), pretransplant (pre), within the first 5 months posttransplant (post) and 1 year post transplant (1 year). RESULTS: One hundred and thirty-four patients underwent pancreas transplantation during the 14-year study period. Overall, 1-year patient and graft survival were 95% and 88%. The mean HgbA1C (%) for eval and pre were 8.5(SD ± 1.7) and 8.3(SD ± 1.7), which was significantly higher than post, and 1 year at 5.1(SD ± .6, p < .01) and 5.2(SD ± .6, p < .01). Of those, 38 patients presented with continuous glucose monitors (CGM) +/- pump. Their mean HgbA1C(%) was 8.2(SD ± 1.5) at eval 8.1(SD ± 1.3). These were also significantly higher than post 5.0(SD ± .6, p < .01), and 1 year 5.1(SD ± .5, p < .01). CONCLUSION: Pancreas transplant provides superior glycemic control to continuous glucose monitoring and remains the optimal therapy for appropriately selected patients with diabetes.
