title: Serum concentration of transforming growth factor (TGF)-beta 1 does not predict advanced liver fibrosis in children with chronic hepatitis B.
abstract: OBJECTIVE
  The aim of the study was to evaluate if measurement of TGF-beta1 has clinical usefulness as a marker of liver fibrosis using ROC analysis and to assess its serum concentration during IFN alpha treatment.
  
  
  METHODS
  Fibrosis stage and inflammation grade were assessed according to Batts and Ludwig and Ishak et al. before and 12 months after the end of IFN alpha treatment of 30 children with chronic hepatitis B. TGF-beta1 was measured by means of the quantitative sandwich enzyme immunoassay technique using recombinant human TGF-beta soluble receptor type II as a solid phase pre-coated onto a microplate (R&D System Inc., Minneapolis, USA).
  
  
  RESULTS
  There was no significant correlation between serum TGF-beta1 level and the stage of liver fibrosis. However TGF-beta1 levels in patients before IFN alpha therapy were significantly higher than in controls. IFN alpha treatment did not improve histological fibrosis during 18 months of observation and it did not cause any significant changes in serum TGF-beta1 levels although there was a tendency to decrease its level during therapy and follow-up.
  
  
  CONCLUSIONS
  Serum concentration of TGF-beta1 does not predict advanced liver fibrosis in children with chronic hepatitis B.
