[Hormonal mechanisms of carbohydrate metabolism disorders in chronic pancreatitis]. / Gormonal'nye mekhanizmy narusheniia uglevodnogo obmena pri khronicheskom pankreatite.

The mechanisms of carbohydrate metabolism abnormality were studied in 128 patients suffering from chronic pancreatitis by means of simultaneous measurement in the blood of glucose, insulin, C-peptide and glucagon concentrations both on an empty stomach and after the glucose tolerance test (50 g glucose). Five types of the hormonal mechanisms of hyperglycemia were revealed, caused by derangement of beta-cells for the most part, more rarely by alpha-cells of the pancreas and impairment of interregulation of those cells in chronic pancreatitis. The rate of the hormonal mechanisms of carbohydrate metabolism abnormality was shown to depend on the gravity and duration of chronic pancreatitis whereas blood sugar and insulin response to intravenous injection of glucose in patients with chronic pancreatitis to have characteristic features in common to type I and II diabetes.
