Signs and symptoms
The infant with neonatal hepatitis usually has jaundice that appears at one to two months of age, is not gaining weight and growing normally, and has an enlarged liver and spleen. Infants with this condition are usually jaundiced. Jaundice that is caused by neonatal hepatitis is not the same as physiologic neonatal jaundice. In contrast with physiologic neonatal jaundice, infants with neonatal hepatitis present with dark urine. Infants may also present with delayed growth.
The causes of neonatal hepatitis are many. Viruses that have been identified include cytomegalovirus, rubella virus, hepatitis A and B viruses, herpes simplex viruses, coxsackievirus, echovirus, and paramyxovirus.Metabolic and immune disorders can also cause neonatal hepatitis.Giant cell transformation throughout the parenchyma is common.
