Increased Serum Glypican-3 Is Associated With Liver Stiffness And Hepatic Dysfunction In Children With Biliary Atresia
CLINICAL AND EXPERIMENTAL HEPATOLOGY(2019)
Abstract
Aim of the study: Biliary atresia (BA) is an uncommon disorder of the liver and bile ducts affecting infants and is characterized by progressive fibrosclerosing obstruction of the extrahepatic biliary tree leading to end-stage liver failure. The purpose of this study was to determine serum glypican-3 (GPC3) levels and liver stiffness in children with BA and the correlation of glypican-3 with clinical parameters.Material and methods: Seventy-five post-Kasai BA patients and 28 healthy age-matched controls were registered. Serum GPC3 levels were examined by enzyme-linked immunosorbent assay. Liver stiffness measurement was analyzed by transient elastography.Results: BA patients had significantly greater serum GPC3 and liver stiffness values than controls (p < 0.001). Serum GPC3 and liver stiffness values were significantly higher in jaundiced BA patients than in non-jaundiced BA patients (p < 0.001). Additionally, serum glypican-3 was associated with liver stiffness and serum total bilirubin (p < 0.001, respectively).Conclusions: Elevated serum GPC3 levels were associated with hepatic dysfunction and the severity of BA. As a result, serum GPC3 and liver stiffness might serve as biomarkers reflecting the deterioration of hepatic function and the outcome in post-Kasai BA.
