[The indices of pancreatic incretory activity in patients with chronic pancreatitis and disordered carbohydrate metabolism].

Insulinemia, concentration of C-peptide and glucagon in the blood was studied in chronic hepatitis patients showing moderate tolerance disorders to glucose and diabetes mellitus developed against the background of chronic pancreatitis. Both groups showed hyperglucagonemia. Basal hypoinsulinemia and reduction of the C-peptide level revealed only in patients suffering of chronic pancreatitis with secondary diabetes mellitus. Reduced reaction of beta-cells of the pancreas to physiologic stimulation by pancreosozymin were observed also in less significant disorders of tolerance to glucose. The authors discuss the significance of changes in the sequential development of different degrees of disorders of the carbohydrate metabolism in patients with chronic recurrent pancreatitis.
