title: [Idiopathic neonatal hepatitis].
abstract: Idiopathic neonatal hepatitis is one of the more important causes of neonatal cholestasis. It is regarded one of the clinical presentations of 'idiopathic obstructive cholangiopathy', just like extrahepatic biliary atresia. Is it not possible to discriminate between intrahepatic and extrahepatic causes of neonatal cholestasis, or between idiopathic neonatal hepatitis and metabolic, infectious, or toxic causes, by using clinical or laboratory parameters. Liver histology is slightly more helpful: giant cell formation, focal liver necrosis, and lymphocytic and neutrophilic infiltration may be found in idiopathic neonatal hepatitis. In infectious hepatitis liver pathology mostly is only a lesser part of the symptomatology. Sporadic idiopathic neonatal hepatitis has a better prognosis than familial; about 75% of children with sporadic hepatitis experience complete recovery as compared to less than 25% of children with familial hepatitis. Therapy is confined to the prevention and treatment of complications such as itching, portal hypertension and variceal bleeding, and (fat) malabsorption.
