[Spontaneous changes in carbohydrate tolerance and insulin secretion in persons with indications of disturbed carbohydrate tolerance. Preliminary results and follow-up observations for 7 years].
115 patients with normal weight and 15 adipose persons with suspicion of a disturbance of the carbohydrate metabolism were characterized by means of a glucose infusion test lasting two hours concerning the carbohydrate tolerance and insulin secretion. Longitudinal analyses of the spontaneous behaviour of the carbohydrate tolerance and insulin secretion depending on the degree of the carbohydrate tolerance up to duration of the observation of 7 years. A deterioration of the carbohydrate tolerance was to be proved in 21% of 87 persons with normal carbohydrate tolerance within two years. With normal carbohydrate tolerance within two years. With an increase of the duration of the observation up to 7 years the frequency of disturbances of the carbohydrate tolerance increases to 30%. This development cannot be coordinated to a certain type of insulin secretion. In the individual case a deterioration of the carbohydrate tolerance may be associated with an increase or reduction of the glucose stimulated insuline secretion. An improvement of the carbohydrate tolerance was observed in 15 (54%) of 28 patients with disturbed carbohydrate tolerance within 2 years. In a group with pathological carbohydrate tolerance this development was associated with a significant reduction of the basic and glucose stimulated insulin secretion. In all patients with improved carbohydrate tolerance on the side of the insulin secretion primarily the type of "normal response" was present. The lacking relation between changes of the B-cell function and the carbohydrate tolerance emphasizes the importance of other factors, such as a peripheral insulin resistance, for the development of disturbances in the carbohydrate metabolism.
