Brief Summary:
Hypoglycemia is the principal barrier to the achievement of target glycemic goals in type 2 diabetes. Alcohol consumption is very prevalent in our society and a proven cause of hypoglycemia. Population studies suggest that elderly, insulin requiring type 2 diabetes patients are particularly vulnerable to severe hypoglycemia and that this problem accounts for an estimated $50 million or more in healthcare costs in the USA each year. We hypothesize that low dose ethanol significantly increases the vulnerability to overnight hypoglycemia and impairs the recovery of plasma glucose in elderly, insulin requiring patients with type 2 diabetes. Our preliminary studies suggest that low dose ethanol impairs recovery from day time insulin-induced hypoglycemia in type 2 diabetes patients but not in age matched healthy control subjects. The proposed studies will examine the effects of low dose ethanol on overnight glucose regulation in elderly, insulin requiring type 2 diabetes patients and will establish the mechanism of these impairments through a series of systematic evaluations. Specifically, these studies will document suppression of the dawn phenomenon by ethanol, and/or exacerbation of a deficient counterregulatory response to hypoglycemia during sleep, especially growth hormone. Specific mechanisms for the suppression of growth hormone to be examined include that evening ethanol (3) inhibits peak overnight ghrelin secretion and/or (4) reduces pituitary sensitivity to GHRH. Additionally, these studies will characterize (5) the dose response characteristics of ethanol on overnight glucose homeostasis and will (6) carefully evaluate the effect of the timing of ethanol administration in relation to meal ingestion on overnight hypoglycemic vulnerability. To address these aims, we will assess the effect of moderate doses of orally administered ethanol or placebo on overnight growth hormone release, ghrelin, total IGF-1, free IGF-1, insulin-like growth factor binding protein 1 (IGFBP-1) concentrations, glucose production and other parameters of glucose homeostasis among elderly control subjects versus elderly, insulin requiring subjects with type 2 diabetes. These important studies will provide a scientific basis for the prevention of overnight hypoglycemia (and the attendant cost savings) by providing mechanistic insights into the causes of nocturnal hypoglycemia.
