  • Title: Serum hyaluronic acid as an early prognostic marker in biliary atresia.
    Author: Dhawan A, Trivedi P, Cheeseman P, Baker AJ, Howard ER, Mieli-Vergani G.
    Journal: J Pediatr Surg; 2001 Mar; 36(3):443-6. PubMed ID: 11226992.
    Abstract:
    PURPOSE: The aim of this study was to assess whether serum concentrations of hyaluronic acid (HA), measured at diagnosis is an early biochemical marker of prognosis in biliary atresia. METHODS: Serum HA was measured at diagnosis using a radiometric assay in 84 infants with biliary atresia (BA), and related to outcome by 5 years of age. RESULTS: Serum HA was higher in the 29 patients who died or required liver transplant by 5 years of age compared with the 56 who survived to 5 years without transplant (490 +/- 216 microg/L v 262 +/- 163 microg/L; P <.001, 95% confidence intervals of the difference 145 to 311 microg/L). CONCLUSION: High serum concentrations of HA at diagnosis may help to identify at an early stage those patients with BA who have a poor prognosis and will require liver transplant by 5 years of age.
