In a previous work, we demonstrated that the levels of urinary sulfated bile acids (USBA) and serum total bile acids (TBA) were correlated very well and also that USBA was considered to be a more useful indicator of hepatic fibrosis than TBA in patients with hepatitis C virus (HCV)\u2010related liver diseases. In the current study we aimed to confirm these finding in patients with primary biliary cirrhosis (PBC), a prototypic cholestatic liver disease.<\/jats:p><jats:p><jats:bold>Methods:\u2002<\/jats:bold> Urinary sulfated bile acids were measured using an automatic assay kit in 50 patients with PBC, of whom 11 were diagnosed as having cirrhosis. We obtained specimens before ursodeoxycholic acid (UDCA) administration in four patients, and during UDCA in 46 patients. The correlations between USBA and various laboratory tests were studied.<\/jats:p><jats:p><jats:bold>Results:\u2002<\/jats:bold> The median USBA level was 67.9 \u00b5mol\/g creatinine in PBC; 27.7 without cirrhosis and 210.3 with cirrhosis (<jats:italic>P<\/jats:italic>\u2003=\u20030.001). The number of PBC patients with elevated USBA was significantly higher than those with elevated TBA (82% vs. 56%). This significance was remarkable especially in early stages, non\u2010cirrhotic patients (77% vs. 49%). USBA level was well correlated with TBA (<jats:italic>r<\/jats:italic><jats:sub>s<\/jats:sub>\u2003=\u20030.72), and negatively correlated with platelet (<jats:italic>r<\/jats:italic><jats:sub>s<\/jats:sub>\u2003=\u2003\u22120.34) and albumin (<jats:italic>r<\/jats:italic><jats:sub>s<\/jats:sub>\u2003=\u2003\u22120.31).<\/jats:p><jats:p><jats:bold>Conclusion:\u2002<\/jats:bold> Urinary sulfated bile acids and TBA are well correlated, and together with the findings that USBA is not affected by meals, USBA is considered to be more beneficial and convenient than TBA for earlier detection of fibrosis in
