Pancreatic endocrine insufficiency secondary to destruction of acinar cells is a well known complication of chronic pancreatitis (CP). Of all patients with diabetes mellitus, 0.5-1% is secondary to CP. The frequency of occurrence of diabetes in CP is about 40-60%. This figure varies according to the aetiology, extent of calcification, and duration of the disease. Pancreatic diabetes is more commonly associated with alcoholic and tropical calcific pancreatitis of long duration. The pathophysiology of pancreatic diabetes is related to beta cell failure and reduced insulin secretory capacity. The development of pancreatic diabetes calls for careful evaluation and management to prevent long term complications. Pancreatic cancer is a known complication of chronic pancreatitis and sometimes manifests with new onset diabetes. As destruction of pancreatic tissue in CP leads to depletion of both insulin and glucagon-producing cells of the islets of Langherhans, pancreatic diabetics are usually not prone to ketoacidosis. A trial of oral hypoglycemic agents followed by insulin therapy when the need arises has been the line of management thus far in these patients. This review focuses on the prevalence, unique pathophysiological aspects, clinical features and special issues in the management of diabetes secondary to chronic pancreatitis.
