Autoimmunity May Explain Diabetes in a Subset of Patients With Recurrent Acute and Chronic Pancreatitis: A Pilot Study.

Pancreatogenic diabetes mellitus, also termed type 3c diabetes (T3cD), or glucose intolerance develops in 25%-75% of adults with chronic pancreatitis (CP). The primary pathophysiologic defect in T3cD is insulin deficiency, thought to result largely from "bystander" injury to the islets from fibrotic changes in the exocrine pancreas and cytokine-induced beta cell dysfunction from intrapancreatic inflammation.1 .
