Occasionally, severe neonatal unconjugated hyperbilirubinemia occurs without evident etiologic explanation. The cause of transient neonatal hyperbilirubinemia may be steroidal substances in the plasma and milk of the mother that inhibit conjugation of bilirubin Lucey et al.

The inhibitor was present in these mothers in concentrations 4 to 10 times that in other pregnant mothers.

The inhibitor is probably a progestational steroid. Three of the 16 died of kernicterus, and one was left with quadriplegic cerebral palsy. The mothers do not show hyperbilirubinemia, probably because of a large functional reserve.

This is an interesting genetic disease of which there are few examples–one in which the genotype of the mother is responsible for the disease in the infant. Another example is mental retardation in the offspring sriscoll women with phenylketonuria Mabry et al. The ethnic background of these mothers and the presence or absence of consanguinity in their parents would be of interest. The same condition may be present in unusually high frequency in Yemenite Jews Sheba, Transient nonhemolytic unconjugated hyperbilirubinemia is observed in breast-fed but not bottle-fed babies of mothers whose breast milk contains pregnane-3 alpha ,20 beta -diol that competitively inhibits hepatic glucuronyltransferase activity in vitro.

Serum from these mothers contains no more inhibitory substance than does normal pregnancy serum. Kernicterus has not been observed, probably lucye severe jaundice does not develop until the seventh to tenth day, when the infant’s blood-brain barrier has become relatively impermeable to unconjugated bilirubin Arias et al. In infants with uninterrupted breastfeeding, the hyperbilirubinemia disappeared slowly and could still be detected 12 weeks after birth.

The familial incidence was Late neurodevelopmental or hearing defects were not observed, thus enabling the pediatrician to encourage continuation of breastfeeding in most cases of healthy infants with breast milk jaundice. Sex and body weight at birth were not significantly different between the 2 groups. When breastfeeding was stopped, the serum bilirubin levels began to decrease in all cases, but when breastfeeding was resumed, the serum bilirubin concentration again became elevated in some infants.

Serum bilirubin levels normalized by the time the infants were 4 months old. Sequencing of UGT1A1 revealed that 8 infants were homozygous and 7 heterozygous for a missense mutation The authors suggested that breastfeeding jaundice may be an infantile and inducible phenotype of Gilbert syndrome.

Another UGT1A1 missense mutation However, maximal body weight loss during the neonatal period was the only independent risk factor for the development of neonatal hyperbilirubinemia odds ratio of 1. Production of unconjugated hyperbilirubinaemia in full-term new-born infants following administration of pregnane-3 alpha20 beta -diol.
