Abstract:A B S T R A C T Hepatic secretions of biliary lipids were estimated in 43 patients with and without cholesterol gallstones. Studies were carried out by a marker dilution technique employing duodenal intubation with a threelumen tube. Hourly secretion rates of cholesterol, bile acids, and phospholipids were determined during constant infusion with liquid formula.In 17 American Indian women with gallstones, hourly outputs of biliary bile acids were significantly less than those in 7 Indian men and 12 Caucasian w… Show more
“…[41] that cholesterol secretion in obese gallstone subjects is greater than in obese non-gallstone subjects seems, however, to suggest that a metabolic defect may be present in the former group of subjects superimposed on the well-known cholesterol hypersecretion of obesity. Combined solvent deficiency and solute excess has also been reported by Grundy et al [99] in American Indian women with cholesterol gallstones. In this study also most of the patients were obese, and this condition may act as an additional cause of excess cholesterol secretion.…”

“…Obesity is a well-established risk factor for NASH and a major risk factor for developing gallstones (7).The risk for gallbladder stones is especially high if obesity onsets in yo- uth. Gallbladder stones are closely related to central obesity, diabetes mellitus and insulin resistance (8,9). Other shared risk factors include dyslipidemia (hypertriglyceridemia, low HDL-C) and abnormalities in fibrinolysis and coagulation (10).…”
“…Our results give rise to the possibility that regulation of liver SCP-2 activity may influence both the intrahepatic cholesterol compartmentalization and sterol balance in the whole animal. Finally, it could be possible that some high biliary cholesterol secretory states, such as those associated with obesity and gallstone disease [3,58], could be mediated by liver SCP-2 overexpression. …”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
