Low Insulin Response

ABSTRACT The insulin response during a standardized glucose infusion (GIT) was studied in a group of 13 monozygotic twin pairs previously registered as consisting of one diabetic/one non-diabetic member. At the time of the study three of the non-diabetic subjects had developed overt diabetes and three decreased glucose tolerance only. Of the non-diabetic members all but one (with diabetes due possibly to chronic pancreatitis in the sibling) showed an insulin response similar to that seen in diabetic subjects, and in healthy subjects previously assumed to be potential diabetics. The present study therefore supports our earlier suggestion that a low insulin response characterizes potential diabetes. There was a striking similarity between the insulin curves in the twin pairs, irrespective whether diabetes occurred in one, in both or in none of the members. It is suggested as a working hypothesis that the type of insulin response to glucose infusion is genetically determined, and that a low insulin response is a prerequisite for the development of diabetes mellitus.

Low Insulin Response

ABSTRACT A decreased insulin response to glucose administration has been suggested to be a prerequisite for the development of diabetes mellitus. Factors that increase the demand for insulin in the organism may precipitate diabetes in subjects with a low insulin response to a glucose infusion test (GIT). Since it is well-known that pregnancy is a diabetogenic factor, its effect on the carbohydrate metabolism of subjects with a low insulin response was studied. During pregnancy, the insulin response of the low responders was enhanced as in the controls, but at all stages the insulin response was significantly less than in the controls. None of the subjects developed glucose intolerance during pregnancy. The fasting blood glucose and plasma insulin levels and the k-value in intravenous glucose tolerance tests (IVGTT) were modified according to similar patterns in both groups. The sensitivity to endogenous insulin was significantly greater in the low insulin responders but was reduced to a greater extent than in the controls towards the end of pregnancy. In four of the 11 low insulin responders the initial insulin response to glucose in the last trimester was lower than in mid-pregnancy. This occurred only in one out of 14 high insulin responders. It is suggested that gestational diabetes occurs in those low insulin responders who demonstrate either a dramatic decrease in insulin sensitivity, or limitations in the enhancement of insulin release, or, more likely both conditions.

ABSTRACT In a previous paper it was shown that 15 out of 85 healthy subjects with a normal intravenous glucose tolerance demonstrated a low plasma insulin response to glucose infusion which was similar to that obtained in diabetic subjects. In the present paper it has been shown that the type of insulin response to glucose infusion was the same when the test was repeated. Low insulin responders to glucose infusion, as a group, also showed low insulin response to intravenous tolbutamide and oral glucose. This indicates that the type of insulin response is characteristic for a given subject irrespective of the stimulation used. There seemed to be no difference in the occurrence of diabetes in the family history of the groups of low and high insulin responders.

Low Insulin Response

ABSTRACT It has earlier been postulated that a low insulin response to a glucose infusion is characteristic for the prediabetic individual (Cerasi & Luft 1967c). There is also evidence that some infants of individuals with low insulin response might have a carbohydrate metabolism that is in some respects similar to that of newborn infants to diabetic mothers (Edström et al. 1974). In the present study 15 infants to low insulin responders (ILR) and 22 infants to high insulin responders (IHR) were subjected to an intravenous glucose load (IVGTT) at 2–24 h age. A significant difference in glucose tolerance was found between the groups, the mean k-value for the ILR being 1.39 ± 0.41 and that for the IHR 1.05 ± 0.09 (P < 0.05). No mothers were found to have a gestational diabetes (with the possible exception of one low insulin responders) but during late pregnancy the mean k-value at IVGTT in the low responders decreased from nonpregnant values (the mean difference being 0.41 ± 0.20, P < 0.025) while the high responders did not show a corresponding decrease (mean difference 0.12 ± 0.25, P > 0.05). No other differences between the groups of infants that could influence the k-value could be found apart from the mothers being low or high insulin responders. Our findings show that a low insulin response in the mothers might affect the glucose tolerance of the foetus even in the absence of continuous maternal hyperglycaemia in late pregnancy.

Plasma glucose clearance rates were lower (P < 0.10) in wethers fed the high potassium (0.32% Mg-4.90% K) diet compared with those of the control (0.32% Mg-0.75% K). Insulin responses to glucose infusion and feeding tended to be reduced in wethers fed the high potassium diet as compared to the control.

Insulin Response To Glucose

An analogue computer model has been constructed for the analysis of the interrelationship between blood glucose and plasma insulin concentrations during glucose infusion. The model presented gives quantitative information on the effect of plasma insulin on glucose uptake, the total amount of glucose taken up by the tissues at a given time, the effect of blood glucose on the release of stored and newly formed insulin, and the rapidity by which plasma insulin is increased in response to hyperglycaemia. Such an analogue computer model might be a useful tool in the investigation of the various dynamic factors involved in the glucose- insulin interrelationship.

Plasma Insulin Response

ABSTRACT Plasma insulin response to glucose infusion was found to be markedly increased in 20 patients with active acromegaly and with normal intravenous glucose tolerance. The insulin response was more pronounced in patients with highly active acromegaly than in those showing moderately active disease. In five patients with active acromegaly and with decreased glucose tolerance the insulin response was delayed and smaller than normal, i. e. similar to that seen in diabetic subjects without acromegaly. After successful treatment of the acromegaly insulin response to glucose infusion was normalized in the patients with normal glucose tolerance. In those with decreased glucose tolerance the diabetic type of insulin response remained unchanged even when the glucose tolerance was normalized. It is suggested that diabetes in connection with acromegaly develops only in prediabetic individuals, i.e. subjects with decreased insulin response to hyperglycaemia, who are unable to overcome the diabetogenic effect of growth hormone by compensatory hyperinsulinism.
