Elevated serum heat shock protein 70 and liver stiffness reflect hepatic dysfunction and severity in postoperative biliary atresia

2017 Pediatric Surgery International 33;8 (893-899)

BACKGROUND: Biliary atresia (BA) is a severe chronic liver disease characterized by progressive obstructive cholangiopathy of biliary tract. Heat shock protein 70 (HSP70) is involved in protecting cells against a wide variety of stress and plays a protective role in tissue damage. The purpose of this study was to investigate serum HSP70 and liver stiffness in BA and determine the association of serum HSP70, liver stiffness, and outcome parameters in post-Kasai BA patients. METHODS: One hundred post-Kasai BA patients and 40 controls were enrolled. Serum HSP70 levels were analyzed using enzyme-linked immunosorbent assay. Liver stiffness values were assessed by transient elastography. RESULTS: BA patients had significantly higher serum HSP70 and liver stiffness values than controls. Serum HSP70 and liver stiffness values were markedly elevated in BA patients with jaundice compared to those without jaundice (P
