Effects of glyburide on in vivo insulin-mediated glucose disposal

The American Journal of Medicine

Abstract

The purpose of this study was to examine the effects of glyburide on peripheral (muscle) and hepatic insulin sensitivity in patients with non-insulin-dependent diabetes mellitus (NIDDM) and insulin-dependent diabetes mellitus (IDDM) as well as in healthy control subjects. In protocol 1, 10 patients with NIDDM and seven young healthy control subjects were studied. Changes in insulin sensitivity (40 mU/m2.min euglycemic insulin clamp), hepatic glucose production (3-[3H]glucose turnover), and insulin secretion (+125 mg/dL hyperglycemic clamp) were measured before and after 3 months (in patients with NIDDM) and 6 weeks (in young control subjects) of glyburide therapy. In protocol 2, five patients with IDDM and eight patients with insulin-treated NIDDM were evaluated before and after two months of glyburide therapy (20 mg per day). Changes in daily insulin requirements, 24-hour plasma glucose profiles, glycohemoglobin, glucagon-stimulated C-peptide secretion, insulin sensitivity, and hepatic glucose production were measured. In protocol 1, glyburide significantly improved insulin sensitivity (p less than 0.01) and insulin secretion (p less than 0.01) in the NIDDM patients. The elevated rates of hepatic glucose production (2.4 +/- 0....Continue Reading

Biomarkers for Type 2 Diabetes

Biomarkers can help understand chronic diseases and assist in risk prediction for prevention and early detection of diseases. Here is the latest research on biomarkers in type 2 diabetes, a disease in which the body is unable to produce or properly use insulin.

Autoimmune Diabetes & Tolerance

Patients with type I diabetes lack insulin-producing beta cells due to the loss of immunological tolerance and autoimmune disease. Discover the latest research on targeting tolerance to prevent diabetes.
