Abstract

Background: Current therapy for Type 1 diabetes (T1D) is characterized by significant glucose variability (GV). Pancreas transplantation (PT) is performed in certain T1D patients with and without end-stage renal disease. To date, GV has been examined to a limited extent after PT. Methods: We investigated GV using continuous glucose monitoring (CGM) 3-6 weeks after PT. Results: Eleven patients had simultaneous kidney pancreas transplantation (SPK), nine pancreas after kidney (PAK), and six pancreas transplantation alone (PTA). Mean CGM showed no difference between SPK, 126.5 ± 13.9, PAK 119.9 ± 12.8, and PTA 131.1 ± 29 mg/dL (P value.6). Percentage of time in range (TIR, 70-180 mg/dL) was 92% for SPK, 93.4% in PAK, and 88.5% in PTA with only 0.3%, 1.5%, and 0.3% of time <70 mg/dL. Percentage >180 mg/dL was 7.9% for SPK, 4.9% PAK, and 11% in PTA. Other measures of GV were similar in the three cohorts. In six patients, CGM was performed before and after PT and improved significantly. GV was also better compared with a matched cohort of T1D patients. Conclusions: All 3 types of PT resulted in excellent glucose control 3-6 weeks post-procedure. CGM outcomes represent an important objective outcome after PT.
