Influence of short-term administration of clofibrate on insulin and glucagon response to protein ingestion in man. 1978

F Fery, and E O Balasse

Nine normal and two mildly hypertriglyceridemic subjects were treated with 2 g of clofibrate per day for 8 days. A significant fall in serum triglyceride and cholesterol concentration was observed from the second day onwards whereas free fatty acid levels were minimally affected. Insulin and glucagon responses to the ingestion of 200 g of meat were tested before and at the end of clofibrate treatment. Insulin response was significantly depressed (-28 +/- 12%) by the drug whereas glucagon response was enhanced but not to a significant degree. The ratio between insulin response and glucagon response was decreased by 38 +/- 11% (p less than 0.01) after treatment. A positive correlation was observed between the effects of clofibrate on basal triglyceride concentration on one hand and the effects of the drug on insulin and insulin/glucagon response to the protein meal on the other hand. Since insulin and glucagon are known to influence triglyceride metabolism, our data are compatible with the concept that the hypotriglyceridemic effect of clofibrate is--at least partly--related to the observed changes in insulin and glucagon reactivity.

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).

D008055 Lipids A generic term for fats and lipoids, the alcohol-ether-soluble constituents of protoplasm, which are insoluble in water. They comprise the fats, fatty oils, essential oils, waxes, phospholipids, glycolipids, sulfolipids, aminolipids, chromolipids (lipochromes), and fatty acids.

D005934 Glucagon A 29-amino acid pancreatic peptide derived from proglucagon which is also the precursor of intestinal GLUCAGON-LIKE PEPTIDES. Glucagon is secreted by PANCREATIC ALPHA CELLS and plays an important role in regulation of BLOOD GLUCOSE concentration, ketone metabolism, and several other biochemical and physiological processes.
