Bilirubin is a product of this last process and the accumulation in the blood causes yellow staining on the skin. Several of these texts also describe a lethal course in infants who probably had Rh isoimmunization. Preterm Infants: •Incidence of visible jaundice is much higher than in term infants.

NEONATALJAUNDICE Jaundice is clinically detectable in the newborn when the serum bilirubin levels are greater than 85 μmol/L. [3] Neonatal hyperbilirubinemia is extremely common because almost every newborn develops an unconjugated serum bilirubin level of more than 30 µmol/L (1.8 mg/dL) during the first week of life. Newborns produce more bilirubin than adults do because of greater production and faster breakdown of red blood cells in the first few days of life. Hepatic excretory capacity is low both because of low concentrations of the binding protein ligandin in the hepatocytes and because of low activity of glucuronyl transferase, the enzyme responsible for binding bilirubin to glucuronic acid, thus making bilirubin water soluble (conjugation). An increase in the concentration of bilirubin above 3 mg per dL of blood causes jaundice. Christensen RD, Yaish HM. Incidence figures are difficult to compare because authors of different studies do not use the same definitions for significant neonatal hyperbilirubinemia or jaundice. Maisels MJ, Newman TB.

The same is true for many total serum bilirubin values obtained in neonatal jaundice. Next, water-soluble biliverdin is reduced to bilirubin, which, because of the intramolecular hydrogen bonds, is almost insoluble in water in its most common isomeric form (bilirubin IXα Z,Z). Outcomes among newborns with total serum bilirubin levels of 25 mg per deciliter or more. Greeks living in Greece have a higher incidence than those of Greek descent living outside of Greece.

Extreme hyperbilirubinaemia in term and near-term infants in Denmark. In 1984, Moore et al reported 32.7% of infants with serum bilirubin levels of more than 205 µmol/L (12 mg/dL) at 3100 m of altitude. J Perinatol. However, in some infants, serum bilirubin levels may rise excessively, which can be cause for concern because unconjugated bilirubin is neurotoxic and can cause death in newborns and lifelong neurologic sequelae in infants who survive (kernicterus). In the first oxidation step, biliverdin is formed from heme through the action of heme oxygenase, the rate-limiting step in the process, releasing iron and carbon monoxide.
