Thirty-eight non-insulin-dependent diabetic patients within 130% of desirable body weight were given a 100-g oral glucose tolerance test (OGTT) at diagnosis and after at least 1 mo of dietary treatment with energy and carbohydrate restriction. Thirteen "responders" showed an improvement in fasting blood glucose, glucose tolerance, and insulin secretion, with near-normalization of plasma, lactate, pyruvate, free fatty acids, glycerol, and ketone bodies. There were no significant changes in the 25 "non-responders." The responders were, at diagnosis, heavier than the non-responders (75.5 versus 64.3 kg, P less than 0.01). Twenty non-responders subsequently completed a prospective controlled study of glibenclamide, chlorpropamide, and placebo lasting for 16 mo with OGTTs at the end of each 4-mo treatment phase. The results showed that there were no significant differences between the metabolic effects of glibenclamide and chlorpropamide. On active treatment, insulin levels rose coincident with a fall in fasting blood glucose and an improvement in glucose tolerance and near-normalization of plasma lactate, pyruvate, free fatty acids, glycerol, and ketone bodies, all of which relapsed to initial values after placebo. Ten years after the initial study, 29 of the original patients were traced and reviewed and the outcome related to their earlier tests. Twenty-two percent of the responders and 70% of the non-responders were now on insulin (P less than 0.02); the initial insulin response to OGTT at the end of the diet treatment was significantly lower in those subsequently treated with insulin (P less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
