title: Early onset conjugated hyperbilirubinemia in newborn infants.
abstract: OBJECTIVE
  To determine the causes and related outcomes of early onset conjugated hyperbilirubinemia in a group of newborn infants and to determine the incidence of sepsis in these neonates.
  
  
  METHODS
  The charts of 42 babies with conjugated hyperbilirubinemia were retrospectively reviewed.
  
  
  RESULTS
  The mean gestational age was 37 weeks and the mean postnatal age at presentation was 10 days. Culture-proven sepsis was identified in 15 babies (35.7% of total). Gram-negative bacteria were isolated in 10 cases and E. coli was the most common of these agents (7 cases). Perinatal hypoxia-ischemia was the second most frequent etiology (7 patients; 16.7% of total). The other diagnoses were blood group incompatibility (n=5), Down syndrome (n=3), cholestasis associated with parenteral nutrition (n=3), neonatal hepatitis (n=2), metabolic liver disease (n=1), biliary atresia (n=1), portal venous thrombosis (n=1) and unknown (n=4). Thirteen babies with sepsis recovered completely with treatment, whereas the prognosis for those with perinatal hypoxia-ischemia was grave (six of seven died).
  
  
  CONCLUSIONS
  The findings suggest that early onset cholestatic jaundice in newborn infants is more commonly from non-hepatic causes, so it is reasonable to monitor these infants carefully for a period of time before undertaking time-consuming or invasive investigations towards a primary liver disease.
