BACKGROUND Most patients with primary biliary cirrhosis (PBC) are treated with ursodeoxycholic acid (UDCA); however, some do not respond fully. PBC is also associated with dyslipidemia, but a link with vascular risk has not been confirmed. METHODS AND RESULTS In this study we compared UDCA monotherapy with fenofibrate plus UDCA in PBC patients with incomplete biochemical response to UDCA mono...

This article is available online at http://www.jlr.org UDCA to partially block the transmembrane apical Na + dependent bile acid transporter ( 7 ). Thus far, no intracellular receptor for UDCA has been reported. The farnesoid X receptor  (FXR ) is a nuclear receptor that binds to and is activated by bile acids ( 8–10 ). FXR forms heterodimers with the retinoid X receptor  (RXR ) and regulate...

The activity of 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) reductase and 7alpha-hydroxylase, the enzymes controlling the rate of hepatic synthesis, respectively, of cholesterol and bile acids, and the microsomal cholesterol content were evaluated in 25 patients with cholesterol gallstones and 17 subjects without gallstones. The same quantities were estimated in 16 additional patients with gallsto...

BACKGROUND & AIMS We tested the hypothesis that oral administration of bile salts, which are known to increase the biliary excretion of unconjugated bilirubin (UCB), decreases unconjugated hyperbilirubinemia in the Gunn rat model. METHODS Adult Gunn rats were fed a standard diet or the same diet supplemented with 0.5 weight % ursodeoxycholic acid (UDCA) or cholic acid (CA) for 1 or 6 weeks. U...

The present study has been directed to investigate Ursodeoxycholic Acid (UDCA) effect in children, to reduce the high Liver transaminases induced by Anticonvulsant drugs (drug induced hepatitis). This idea has been driven from Cytoprotective and antioxidant properties of UDCA to be used in drug induced inflammation in Liver. Twenty two epileptic patients aged between 4 mo - 3 yr whom were under...

Intrahepatic cholestasis of pregnancy (ICP) is a pregnancy-specific liver disorder associated with an increased risk of adverse fetal outcomes. It is characterised by raised maternal serum bile acids, which are believed to cause the adverse outcomes. ICP is commonly treated with ursodeoxycholic acid (UDCA). This study aimed to determine the fetal and maternal bile acid profiles in normal and IC...

Medical dissolution of gallstone is usually performed on radiolucent gallstones in a functioning gallbladder. However, absence of visible gallstone on plain abdominal x-ray does not always preclude calcification. This study aims to compare the response and dissolution rates between ursodeoxycholic acid (UDCA) alone or in combination with chenodeoxycholic acid (CDCA) according to stone density o...

Postprandial secretion of glucagon-like peptide-1 (GLP-1) is enhanced after Roux-en-Y gastric bypass (RYGB), but the precise molecular mechanisms explaining this remain poorly understood. Plasma concentrations of bile acids (BAs) increase after RYGB, and BAs may act as molecular enhancers of GLP-1 secretion through activation of TGR5-receptors. We aimed to evaluate GLP-1 secretion after oral ad...

Bile acid-sensitive ion channel (BASIC) is a member of the DEG/ENaC gene family of unknown function. Rat BASIC (rBASIC) is inactive at rest. We have recently shown that cholangiocytes, the epithelial cells lining the bile ducts, are the main site of BASIC expression in the liver and identified bile acids, in particular hyo- and chenodeoxycholic acid, as agonists of rBASIC. Moreover, it seems th...

BACKGROUND In animal models ursodeoxycholic acid (UDCA) showed a chemoprotective effect against colon cancer. To explain this, a reduced proliferation of the colorectal mucosal proliferation was suggested. We, therefore, examined the influence of UDCA on the proliferation of normal colorectal mucosa in humans. METHODS Following endoscopic polypectomy, 20 patients with colorectal adenomas were...
