Liver disease in the newborn usually presents with two main distinct clinical syndromes:neonatal cholestasis and neonatal liver failure; in both cases, an urgent diagnosis is required.

Abstract

Liver disease in the newborn usually presents with two main distinct clinical syndromes:neonatal cholestasis and neonatal liver failure; in both cases, an urgent diagnosis is required. Cholestasis usually presents with prolonged aundice or, less frequently, with a hemorrhagic syndrome related to late onset vitamin K deficiency. Cholestatic jaundice is associated with discolored stools and dark urines due to hyperbilirubinuria. Cholestasis affects approximately1 in every 2,500 infants and its etiologicalspectrum is particularly wide, including conditions with severe prognosis. Diagnostic approach to a prolonged jaundice belongs to primary care pediatrician and includes diagnosing of its eventual cholestatic nature by evaluating abnormal stool or urine color and by measuring total and direct serum bilirubin;preventing of the hemorrhagic complications related to vitamin K deficiency by administrating a single intramuscular dose of vitamin K1; early suspecting biliary atresia in case of suggestive clinical picture, since the favorable outcome of surgery also relies on its precocity; and early referring the infant to a center experienced in the treatment of hepatobiliary disordersin childhood. Neonatal acute liver failure (NALF) is a rare and challenging condition. NALF is a multietiologic syndrome which is difficult to recognize initially. As important as he recognition of causes that may indicate specific diet and medical therapy is the selection of infants suitable for liver transplantation since mortality is high and only 25 %of infants survive with their native liver. Management of NALF requires supporting the neonate until liver regeneration or liver transplantation takes place.
