Urinary bile acid sulfate levels in patients with hepatitis C virus-related chronic liver diseases.

Aim: Urinary bile acids are mainly conjugated with sulfuric acid, and urinary sulfated bile acid (USBA) levels in hepatobiliary diseases have been reported. However, the relationship between USBA and fasting serum total bile acid (TBA) has not been studied in hepatobiliary diseases. In the present study, we measured USBA levels in patients with hepatitis C virus-related chronic liver diseases, and the relationship between TBA and various laboratory tests was studied.
