Filter by:Epinephrine is one of the important hormones in the defense of hypoglycemia. We will test the hypothesis that antecedent hypoglycemia will blunt the metabolic, neuroendocrine and cardiovascular effects of subsequent epinephrine infusion in Type 1 DM.
The purpose of this study is to determine if either hypoglycemia or exercise cause differential responses in muscle and skin sympathetic nerve activity.
This study will look at two FDA approved medications that improve how the pancreas works in patients with Type 2 Diabetes. In order to understand how these medications work in patients with diabetes we must first measure the normal response in healthy volunteers without diabetes. We will be looking at the body's normal physiological response to low blood sugar and whether this will be modified by these medicationsThe hypothesis would be that glimepiride induced insulin secretion will be inhibited by hypoglycemia.
The purpose of this study is to determine what corticosteroid receptor (and the dose of) is responsible for cortisol inducing hypoglycemia associated autonomic dysfunction in Type 1 DM. Specifically, we aim to determine whether stimulating the type 1 corticosteroid receptor (via fludrocortisone), the type 2 corticosteroid receptor (via dexamethasone), or both causes hypoglycemia associated autonomic dysfunction in Type 1 DM.
Elevations of plasma cortisol, a stress hormone, during prior episodes of low blood sugar (hypoglycemia) appear to be responsible for the deficient responses during subsequent hypoglycemia. Our specific aim is to determine if dehydroepiandrosterone (DHEA), a hormone with anti-corticosteroid actions, can prevent hypoglycemia associated autonomic failure in type 1 diabetic volunteers.
The primary objective of this study will be to compare the glucose level at which counter-regulatory hormone responses occur during hypoglycemia in young children with diabetes, with the glucose level counter regulatory hormone responses that occur in older children with diabetes.
When a patient with Type 1 diabetes exercises, he or she is more prone to low blood sugar, or hypoglycemia. It is known that antecedent exercise can blunt defense responses, called counterregulatory responses to subsequent hypoglycemia in Type 1 DM, causing him or her to be vulnerable to another bout of hypoglycemia. Epinephrine is one of the important hormones in the defense of blood glucose during both exercise and hypoglycemia. We will test the hypothesis that antecedent exercise will blunt the metabolic, neuroendocrine and cardiovascular effects of subsequent epinephrine infusion in Type 1 DM.
The studies proposed in this application seek to use non-invasive techniques to examine the impact of repeated hypoglycemia on the brain.
It is unclear what effect selective serotonin reuptake inhibitors (SSRIs) have on hypoglycemia. Thus, the American Hospital Formulary Service recommends careful monitoring of blood glucose levels in all patients with diabetes initiating or discontinuing SSRIs (Katz et al., 1996). Because of the increased prevalence of depression in those with diabetes, it is critical to discover what affect the antidepressant therapy may have on counterregulatory responses to hypoglycemia. This study hypothesizes that chronic administration of SSRIs may result in a blunted counterregulatory response to hypoglycemia, thereby leaving individuals more susceptible to hypoglycemia.
Alprazolam (Xanax) will blunt the body's ability to defend itself from low blood sugar.
