Abstract:
BACKGROUND:Despite the success rate of solitary pancreas transplantation in type 1 diabetes with preserved kidney function has greatly improved in recent years, a residual proportion of failures persists. METHODS:With the aim of investigating autoimmunity as an unrecognized cause of graft failure, we measured autoantibodies to glutamic acid decarboxylase (GADA), insulinoma-associated protein 2 (IA-2A) and the recently discovered zinc transporter 8 antigen (ZnT8A) in 25 recipients of technically successful solitary pancreas transplantation. RESULTS:The overall pancreas graft survival was 92%, 88%, and 80% at 2, 4, and 6 years, respectively. Fourteen patients (56%) had one or more autoantibodies before transplantation, with no effect on subsequent pancreas graft outcome. After transplantation, major autoantibody changes (serum conversion from negative to positive, spreading from one to multiple autoantibodies, or titer increase) were observed in 5 of 25 recipients: in four patients, the autoantibody change was followed by the loss of graft function (95% sensitivity, 80% positive predictive value), with a significantly lower graft survival compared with patients without autoantibodies (P<0.0001). The addition of ZnT8A to GADA and IA-2A increased the number of identified autoantibody changes from three to five of 25 recipients and the number of predicted graft function loss from two to four out of five graft losses. CONCLUSIONS:Detection of major autoantibody changes after technically successful solitary pancreas transplantation is predictive of subsequent loss of graft function. ZnT8A in addition to GADA and IA-2A are a useful marker to be included in the screening panel of posttransplant immune monitoring.
