Biliary squalene levels in hepatobiliary disease.
Following overnight fasting, biliary levels of squalene, bile salts, cholesterol and phospholipid were estimated using human bile obtained with a duodenal double lumen catheter after administration of caerulein. While the squalene level in B-bile was 6.86 microM in the control group, it fell significantly in patients with parenchymal liver diseases, especially liver cirrhosis. There was no significant change in the level in patients with cholelithiasis. Biliary squalene concentration showed a significant correlation with concentrations of bile salts, cholesterol and phospholipid. These results substantiate the possibility that the biliary squalene level reflects sterol metabolism in the liver.
