The influence of short-term thiazide treatment on peripheral tissue and liver sensitivity to insulin in insulin-dependent diabetes mellitus was determined by the euglycemic insulin clamp technique. A sequential three-step hyperinsulinemic clamp was performed in six insulin-dependent diabetics before and after 2 wk of hydroflumethiazide (HFT) administration in a daily dose of 75 mg. Insulin was infused at rates of 0.5, 2.0, and 4.0 mU X kg-1 X min-1, and each dose was given for at least 120 min. Glucose uptake during the last 30 min of each step was almost identical in the two situations (2.7 +/- 0.6 vs. 2.4 +/- 0.5 mg X kg-1 X min-1, 9.6 +/- 0.9 vs. 9.7 +/- 1.2 mg X kg-1 X min-1, and 12.0 +/- 1.3 vs. 12.6 +/- 1.5 mg X kg-1 X min-1). Serum insulin levels were also similar, and blood glucose was kept at 100 +/- 3, 99 +/- 4, and 97 +/- 3 mg/dl before thiazides and at 93 +/- 6, 93 +/- 6, and 94 +/- 6 mg/dl after thiazides. Another five insulin-dependent diabetics were infused with tritiated glucose followed by insulin infusion at two rates: 0.45 and 1.0 mU X kg-1 X min-1. Basal glucose output was comparable before and after thiazides (3.63 +/- 0.24 vs. 2.97 +/- 0.26 mg X kg-1 X min-1), as was the liver response to increasing insulin concentrations. The metabolic state as assessed by HbA1c and fasting blood glucose did not differ in the two experiments.(ABSTRACT TRUNCATED AT 250 WORDS)

UI MeSH Term Description Entries
D007328 Insulin A 51-amino acid pancreatic hormone that plays a major role in the regulation of glucose metabolism, directly by suppressing endogenous glucose production (GLYCOGENOLYSIS; GLUCONEOGENESIS) and indirectly by suppressing GLUCAGON secretion and LIPOLYSIS. Native insulin is a globular protein comprised of a zinc-coordinated hexamer. Each insulin monomer containing two chains, A (21 residues) and B (30 residues), linked by two disulfide bonds. Insulin is used as a drug to control insulin-dependent diabetes mellitus (DIABETES MELLITUS, TYPE 1).

D003922 Diabetes Mellitus, Type 1 A subtype of DIABETES MELLITUS that is characterized by INSULIN deficiency. It is manifested by the sudden onset of severe HYPERGLYCEMIA, rapid progression to DIABETIC KETOACIDOSIS, and DEATH unless treated with insulin. The disease may occur at any age, but is most common in childhood or adolescence.
