  2. Neonatal jaundice - Wikipedia

    en.wikipedia.org/wiki/Neonatal_jaundice

    In newborns, jaundice tends to develop because of two factors—the breakdown of fetal hemoglobin as it is replaced with adult hemoglobin and the relatively immature metabolic pathways of the liver, which are unable to conjugate and so excrete bilirubin as quickly as an adult. This causes an accumulation of bilirubin in the blood ...

  3. Neonatal cholestasis - Wikipedia

    en.wikipedia.org/wiki/Neonatal_cholestasis

    Neonatal cholestasis refers to elevated levels of conjugated bilirubin identified in newborn infants within the first few months of life. [1] Conjugated hyperbilirubinemia is clinically defined as >20% of total serum bilirubin or conjugated bilirubin concentration greater than 1.0 mg/dL regardless of total serum bilirubin concentration. [2]

  4. Kernicterus - Wikipedia

    en.wikipedia.org/wiki/Kernicterus

    Kernicterus is a bilirubin-induced brain dysfunction. [1] The term was coined in 1904 by Christian Georg Schmorl.Bilirubin is a naturally occurring substance in the body of humans and many other animals, but it is neurotoxic when its concentration in the blood is too high, a condition known as hyperbilirubinemia.

  5. Hemolytic disease of the newborn (ABO) - Wikipedia

    en.wikipedia.org/wiki/Hemolytic_disease_of_the...

    If the bilirubin level is sufficiently high as to cause worry, it can be lowered via phototherapy in the first instance or an exchange transfusion if severely elevated. [citation needed] Phototherapy - Phototherapy is used for cord bilirubin of 3 or higher. Some doctors use it at lower levels while awaiting lab results. [19]

  6. Rotor syndrome - Wikipedia

    en.wikipedia.org/wiki/Rotor_syndrome

    Rotor syndrome (also known as Rotor type hyperbilirubinemia) [2] is a rare cause of mixed direct (conjugated) and indirect (unconjugated) hyperbilirubinemia, relatively benign, autosomal recessive [3] bilirubin disorder characterized by non-hemolytic jaundice due to the chronic elevation of predominantly conjugated bilirubin.

  7. Bilirubin - Wikipedia

    en.wikipedia.org/wiki/Bilirubin

    Hyperbilirubinemia may refer to increased levels of conjugated, unconjugated or both conjugated and unconjugated bilirubin. The causes of hyperbilirubinemia can also be classified into prehepatic, intrahepatic, and posthepatic. [21] Prehepatic causes are associated mostly with an increase of unconjugated (indirect) bilirubin. [21] They include:

  8. Jaundice - Wikipedia

    en.wikipedia.org/wiki/Jaundice

    Hyperbilirubinemia, more precisely hyperbilirubinemia due to the unconjugated fraction, may cause bilirubin to accumulate in the grey matter of the central nervous system, potentially causing irreversible neurological damage, leading to a condition known as kernicterus. Depending on the level of exposure, the effects range from unnoticeable to ...

  9. Lucey–Driscoll syndrome - Wikipedia

    en.wikipedia.org/wiki/Lucey–Driscoll_syndrome

    The common cause is congenital, but it can also be caused by maternal steroids passed on through breast milk to the newborn.It is different from breast feeding-associated jaundice (breast-fed infants have higher bilirubin levels than formula-fed ones).
