ABSTRACT
Type 1 diabetes-associated autoimmune mechanisms have not been thoroughly examined in pancreatitis-associated diabetes. We assessed the prevalence of four islet autoantibodies in serum from a large prospective cohort of patients with acute, recurrent acute, or chronic pancreatitis. Diabetes was present in 11 (12%) of 94 participants with acute pancreatitis, 69 (27%) of 273 with recurrent acute pancreatitis, and 235 (43%) of 560 with chronic pancreatitis. Excluding those with only insulin autoantibody positivity, which is confounded by insulin treatment, islet autoantibodies were identified in 51 (5.5%) of 927 participants, and 30 (3.2%) of 297 were positive for two or more autoantibodies. Our findings suggest pancreatitis may elicit islet autoimmunity in a subset of patients, necessitating prospective longitudinal follow-up.
