Abstract: | Fifteen bile acids in serum of 5 normal subjects and 21 patients with chronic liver diseases were fractionated by high performance
liquid chromatography. Fasting total bile acids (TBA), glycocholic acid, taurocholic acid, glycochenodeoxycholic acid (GCDCA),
and taurochenodeoxycholic acid (TCDCA) were significantly increased in patients with liver cirrhosis as compared with normal
subjects. The cholic acid (CA) level and the ratio of the sum of free and conjugated CA to the sum of free and conjugated
chenodeoxycholic acid (CDCA) were significantly elevated in patients with compensated as compared with decompensated liver
cirrhosis, and were useful for differentiation of the two conditions.
Serum bile acid levels were determined after oral administration of 500 mg of CDCA in the 5 normal subjects and 11 patients
with liver disease. The TBA level reached a peak 90 min after CDCA administration in patients with chronic hepatitis and after
120 min in those with liver cirrhosis. The increase in the TBA level was significantly greater in patients with liver disease
than in normal subjects. CDCA, GCDCA, and TCDCA showed changes similar to those in TBA. In patients with decompensated liver
cirrhosis, the reduction in the TBA and CDCA levels after the peaks was slow, and GCDCA and TCDCA levels continued to increase
until 180 min after the administration of CDCA. The TBA and CDCA levels 180 min after CDCA administration were significantly
different among normal subjects, patients with chronic hepatitis, those with compensated liver cirrhosis, and those with decompensated
liver cirrhosis, suggesting the usefulness of CDCA administration in differentiation of these conditions. |
