Outline of Final Research Achievements |
The objective of this study was to evaluate the post-operative insulin independence in 10 living donor (LD) and 10 brain-dead donor (BD) pancreas transplantations for 20 patients with type I diabetes mellitus by using 11C-methionine PET. Patient survivals were 100% at 5 years for LD transplants and at 2 years for BD transplants. The SUVs of LD and BD pancreas transplants with insulin independence were 7.2 ± 1.8 and 10.4 ± 2.3, respectively. The SUVs of LD pancreas transplants with insulin dependence and BD pancreas transplants with graft failure were 3.6 ± 1.1 and 2.9 ± 1.0, respectively. At 5 years after transplantation, for the LD transplants, the insulin-independent rate was 100% for the graft recipients with an SUV higher than 5, and the median insulin independence duration of the graft recipients with an SUV lower than 5 was 7 month (p < 0.01). The 11C-methionine PET may be a potent modality to predict long-term insulin independence and the avoidance of pancreas graft failure.
