  • Title: Serum cholic and chenodeoxycholic acid conjugates and standard liver function tests in various morphological stages of alcoholic liver disease.
    Author: Tobiasson P, Boeryd B.
    Journal: Scand J Gastroenterol; 1980; 15(6):657-63. PubMed ID: 7209376.
    Abstract:
    Fasting and postprandial serum concentrations of conjugates of cholic (CCA) and chenodeoxycholic (CCDA) acid measured by radioimmunoassay were compared with morphological changes in percutaneous liver biopsies from 49 patients with alcohol abuse. Sulfobromophthalein (BSP) and galactose elimination tests were also performed, and serum levels of aminotransferases (ASAT, ALAT), glutamyltransferase, alkaline phosphatase, and bilirubin were determined. Raised fasting serum concentrations of CCDA were found in 29 patients (59%), whereas elevated fasting serum levels of CCA were found in 19 patients (39%). The mean fasting and postprandial serum bile acid concentrations were significantly higher in patients with hepatofibrosis and cirrhosis than in those with only fatty changes. The extent of the postprandial rise, however, was variable and not significantly different among the various groups. The BSP elimination test was abnormal in 12 patients (25%) but gave normal results in 2 of the 3 patients with cirrhosis of the liver. The galactose elimination rates differed only between patients with normal liver biopsies and patients with cirrhosis of the liver. The serum enzyme levels were not significantly different between the various morphological groups. It is concluded that determinations of fasting serum bile acids, especially CCDA, give more reliable and sensitive information on the degree of liver damage in alcoholic liver disease than BSP and galactose elimination tests or serum enzyme assays.
