dc.description.abstractObjective: Biliary atresia (BA) is the most common neonatal cholestatic disorder and the prime indication for liver transplantation (LTx) in children. Histopathological markers in liver biopsies emerge promise as indicator of early LTx in patients with BA. Method: Ductular proliferation, ductal plate malformations and type I, III, IVand V collagen deposition were evaluated on Kasai portoenterostomy (KPE) and liver transplantation (LTx) biopsies from 36 children with BA. Formalin fixed and paraffin embedded liver biopsies were stained with hematoxylin-eosin, picrosirius-polarization and immunofluorescence methods. There were analyzed liver histoarchitecture, biliary ductus and collagen deposition in hepatic compartments. Pathologic findings were graded according to a 5-point semi-quantitative severity-based scoring system. Impact of these markers was tested on LTx time (<2 year and >2 year). Results: Median age of KPE was 12 weeks (range 6–20) and of LTx was 27 months (range 6–120). In KPE liver biopsies, ductular proliferation, ductal plate malformations and collagen deposition were increased but these parameters presented no association with clinical evolution for early LTx. Furthermore, collagen V prominent deposition was found along of hepatic sinusoids and type I, III and IV were more frequent in portal compartment. Conclusion: These results suggest that histopathological parameters evaluation presented may not determine early LTx in biliary atresia.-
