The glucose tolerance, insulin response and pancreatic exocrine function in patients after acute pancreatitis.

In 25 patients having a history of acute pancreatitis (AP) in anamnesis one year ago and in 12 control subjects the insulin response to oral glucose was investigated and in some cases the exocrine function of pancreas was evaluated. The disturbances in glucose tolerance occurred in about 30% of the patients and were associated with impairment of insulin response and deterioration of exocrine pancreatic function. The double cortisone and glucose load did not influence the glucose tolerance in the patients. In persons investigated during AP and one year later only slight improvement of insulin response was noted. The results support the significance of follow-up studies of carbohydrate tolerance and insulin response in patients after AP for the evaluation of the diabetic risk in such cases.
