The aim of this study was to evaluate the insulin (IRI) response to different stimuli and insulin sensitivity in Type 2 diabetic patients responsive to oral hypoglycaemic agents (OHA) and in Type 2 diabetic patients with secondary failure of OHA (SF), all patients being of normal body weight (relative body weight less than 120%), and the possible role of cyclic AMP in the reduced IRI release. SF patients, without islet cell antibodies (ICA), with hyperglycaemia lasting more than 3 months, underwent tests with i.v. tolbutamide (n = 21), i.v. glucose (n = 14), i.v. glucagon (n = 19), i.v. arginine infusion (n = 18); the arginine infusion was repeated in 12 patients during administration of aminophylline, an inhibitor of phosphodiesterase. The same tests were performed in groups of 8 to 15 OHA patients and in groups of 6 to 17 healthy subjects. During all the tests, blood glucose levels were higher in SF patients, than in OHA patients and in healthy subjects. Both SF patients and OHA patients had no IRI response to glucose; SF patients, in contrast to OHA patients, had a reduced IRI response to tolbutamide and to glucagon. The IRI response to arginine was not different in OHA, in SF patients and in healthy controls, but was significantly enhanced by aminophylline only in healthy controls. Insulin infusions (1.66 mU/Kg/min for 90 min) were performed in OHA patients and in SF patients at blood glucose levels of 150 and of 250 mg/dl: during the last 60 min, the amount of glucose metabolized (M), and the insulin sensitivity (M/I) index were greater in OHA than in SF patients.(ABSTRACT TRUNCATED AT 250 WORDS)
