Subjects in the National Cooperative Gallstone Study undergoing 12 mo of therapy with chenodeoxycholic acid for the dissolution of gallstones (low-dose, 375 mg/day, n =252; high-dose, 750 mg/day, n = 253) had a mean increase in serum cholesterol of 20 mg/dl as compared with a 5 mg/dl increase in the placebo group (n = 258). The effect of chenodeoxycholic acid on lipoproteins was determined in a random subset of the high-dose (n = 136) and placebo (n = 143) groups. For men, the mean baseline adjusted estimated low-density lipoprotein cholesterol level at 12 mo was significantly higher in the high-dose group than in the placebo group (159 vs. 148 mg/dl, p less than 0.01), whereas among women this difference was not demonstrated. Change in low-density lipoprotein cholesterol level was inversely related to baseline cholesterol to an equivalent degree in each group among men and women. Women in the high-dose group had significantly lower very-low-density lipoprotein cholesterol levels than did the corresponding placebo group (27 vs. 32 mg/dl, p less than 0.003). Very-low-density lipoprotein cholesterol levels did not differ significantly between the high-dose and placebo group in men. Treatment did not significantly affect the levels of high-density lipoprotein cholesterol or apoproteins A-I, A-II, or B. Chenodeoxycholic acid therapy produces an increase in total cholesterol and low-density lipoprotein cholesterol but does not alter high-density lipoprotein cholesterol levels.

UI MeSH Term Description Entries
D008074 Lipoproteins Lipid-protein complexes involved in the transportation and metabolism of lipids in the body. They are spherical particles consisting of a hydrophobic core of TRIGLYCERIDES and CHOLESTEROL ESTERS surrounded by a layer of hydrophilic free CHOLESTEROL; PHOSPHOLIPIDS; and APOLIPOPROTEINS. Lipoproteins are classified by their varying buoyant density and sizes. Circulating Lipoproteins,Lipoprotein,Lipoproteins, Circulating
D008075 Lipoproteins, HDL A class of lipoproteins of small size (4-13 nm) and dense (greater than 1.063 g/ml) particles. HDL lipoproteins, synthesized in the liver without a lipid core, accumulate cholesterol esters from peripheral tissues and transport them to the liver for re-utilization or elimination from the body (the reverse cholesterol transport). Their major protein component is APOLIPOPROTEIN A-I. HDL also shuttle APOLIPOPROTEINS C and APOLIPOPROTEINS E to and from triglyceride-rich lipoproteins during their catabolism. HDL plasma level has been inversely correlated with the risk of cardiovascular diseases.

D008077 Lipoproteins, LDL A class of lipoproteins of small size (18-25 nm) and light (1.019-1.063 g/ml) particles with a core composed mainly of CHOLESTEROL ESTERS and smaller amounts of TRIGLYCERIDES. The surface monolayer consists mostly of PHOSPHOLIPIDS, a single copy of APOLIPOPROTEIN B-100, and free cholesterol molecules. The main LDL function is to transport cholesterol and cholesterol esters to extrahepatic tissues.

D008079 Lipoproteins, VLDL A class of lipoproteins of very light (0.93-1.006 g/ml) large size (30-80 nm) particles with a core composed mainly of TRIGLYCERIDES and a surface monolayer of PHOSPHOLIPIDS and CHOLESTEROL into which are imbedded the apolipoproteins B, E, and C. VLDL facilitates the transport of endogenously made triglycerides to extrahepatic tissues. As triglycerides and Apo C are removed, VLDL is converted to INTERMEDIATE-DENSITY LIPOPROTEINS, then to LOW-DENSITY LIPOPROTEINS from which cholesterol is delivered to the extrahepatic tissues.

D002635 Chenodeoxycholic Acid A bile acid, usually conjugated with either glycine or taurine. It acts as a detergent to solubilize fats for intestinal absorption and is reabsorbed by the small intestine. It is used as cholagogue, a choleretic laxative, and to prevent or dissolve gallstones.
