    Abstract:
    A prospective study was undertaken to determine if individual serum bile acid (SBA) levels are clinically useful in differentiating patients with asymptomatic chronic active hepatitis (CAH) from patients with chronic persistent hepatitis (CPH). Fasting and postprandial SBA levels were obtained from 16 patients with CAH, 12 with CPH, and 18 control subjects. Levels of cholylglycine (CG) and total cholic acid conjugates (CCA) were determined by radioimmunoassay. Alanine aminotransferase (ALT) levels were also obtained from each subject. There were no significant differences in the mean fasting and 3-hr postprandial CG or CCA levels between the CPH group and the control subjects. The mean fasting and 3-hr CG and CCA levels were significantly higher for the CAH group than the CPH group (P less than 0.05 for each comparison). A combination of the 3-hr postprandial CG and CCA levels with the ALT levels resulted in a better separation of the two groups. All patients with CAH had either a 3-hr CCA level of 200 micrograms/dl, a 3-hr CG level of 170 microgram/dl, or an ALT level of 120 IU/liter. Using these values, only patients with CPH were misclassified as having CAH, and no control subject reached any of these levels. Although the differences obtained were statistically significant, the separation based on a combination of CG, CCA, or ALT levels may have been fortuitous. Nevertheless, these data suggest that postprandial serum bile acid levels may have clinical utility in identifying patients with asymptomatic chronic hepatitis who are likely to have CAH.
