AIM:To compare the histologic features of the liver in intrahepatic neonatal cholestasis(IHNC)with infectious,genetic-endocrine-metabolic,and idiopathic etiologies. METHODS:Liver biopsies from 86 infants with IHNC were evaluated.The inclusion criteria consisted of jaundice beginning at 3 mo of age and a hepatic biopsy during the 1st year of life.The following histologic features were evaluated:cholestasis,eosinophilia,giant cells,erythropoiesis,siderosis,portal fibrosis,and the presence of a septum. RESULTS:Based on the diagnosis,patients were classified into three groups:group 1(infectious;n=18),group 2(genetic-endocrine-metabolic;n=18),and group 3(idiopathic;n=50).There were no significant differences with respect to the following variables:cholestasis,eosinophilia,giant cells,siderosis,portalfibrosis,and presence of a septum.A significant difference was observed with respect to erythropoiesis,which was more severe in group 1(Fisher's exact test,P=0.016). CONCLUSION:A significant difference was observed in IHNC of infectious etiology,in which erythropoiesis was more severe than that in genetic-endocrine-metabolic and idiopathic etiologies,whereas there were no significant differences among cholestasis,eosinophilia,giant cells,siderosis,portal fibrosis,and the presence of a septum.
