  • Title: Portal venous bile acids in cholesterol gallstone disease: effect of treatment with chenodeoxycholic and cholic acids.
    Author: Einarsson K, Ahlberg J, Angelin B, Björkhem I, Ewerth S.
    Journal: Hepatology; 1985; 5(4):661-5. PubMed ID: 4018738.
    Abstract:
    We determined the serum concentrations of cholic, chenodeoxycholic and deoxycholic acids in portal and peripheral venous blood in 9 gallstone-free patients and 39 patients with cholesterol gallstones during standardized cholecystectomy. An accurate and specific gas chromatographic-mass spectrometric technique was used. The portal venous concentration of total bile acids was similar in gallstone-free and untreated gallstone patients (n = 20); there was no evidence of a reduced hepatic uptake of bile acids in the latter. Treatment with cholic acid (n = 10) was associated with a 70% increase in cholic acid and normal concentration of total bile acids. In chenodeoxycholic acid-treated patients (n = 9), the portal venous concentration of this bile acid was increased 3-fold; total bile acids were increased about 60%. The estimated hepatic uptake of cholic acid was slightly decreased during chenodeoxycholic acid treatment. The results indicate that neither bile acid inflow to the liver nor hepatic bile acid uptake is reduced in fasting patients with cholesterol gallstones, and treatment with chenodeoxycholic acid increases fasting inflow of bile acids to the liver. The latter may contribute to unsaturation of fasting hepatic bile during treatment with chenodeoxycholic acid.
