Clinical value of the determination of fasting glycocholic acid serum levels in patients with liver diseases. A comparison with standard liver tests.
Fasting serum levels of glycocholic acid were measured in 142 patients with benign diffuse liver diseases. A total of 63.4% of the whole group of patients, 86.6% of the cirrhotic patients and 31.7% of the noncirrhotic patients had increased serum levels of glycocholic acid. There were significant correlations with blood liver tests associated with liver disease severity such as prothrombin activity and albumin. There were highly significant differences in glycocholic acid levels according to the histological severity of the liver disease, especially when patients with cirrhosis or chronic active hepatitis were compared to the remaining patients and controls. However, discriminant analysis showed that prothrombin activity and albumin were better than glycocholic acid in predicting the histological severity of liver disease. Glycocholic acid serum levels were relatively independent of cholestasis and cytolysis and appeared to be more linked to liver dysfunction. In conclusion, fasting glycocholic acid measurement can be useful in the evaluation and follow-up of liver diseases as a marker of histological severity, and used in addition to other liver tests.
