ABSTRACT
Biliary atresia (BA) is a severe chronic cholestasis disorder of infants that leads to death if not treated on time. Neonatal hepatitis syndrome (NHS) is another leading cause of neonatal cholestasis confounding the diagnosis of BA. Recent studies indicate that altered bile acid metabolism is closely associated with liver injury and cholestasis. In this study, we systematically measured the bile acid metabolome in plasma of BA, NHS, and healthy controls. Liver bile acids were also measured using biopsy samples from 48 BA and 16 NHS infants undergoing operative cholangiography as well as 5 normal adjacent non-tumour liver tissues taken from hepatoblastoma patients as controls. Both BA and NHS had significantly elevated bile acid levels in plasma compared to normal controls. BA patients showed a distinct bile acid profile characterized by the higher taurochenodeoxycholic acid (TCDCA) level and lower chenodeoxycholic acid (CDCA) level than those in NHS patients. The ratio of the plasma TCDCA to CDCA was significantly higher in BA compared to healthy infants (p
