Patterns of bilirubin staining in nonhemolytic kernicterus. 1986

R G Harper, and E I Kahn, and C G Sia, and D Horn, and R Villi, and C A Hessel

Patterns of bilirubin staining were studied in nine infants with kernicterus related to nonhemolytic hyperbilirubinemia, all weighing less than 1200 g, and nine matched controls. Three staining patterns were disclosed: a localized pattern in the central nervous system of kernicteric infants, with only the thalamus staining significantly often; staining, in extraneural tissues (adrenal, myocardial, renal, and colonic mucosa) only in kernicteric infants, despite similar bilirubin levels in both groups; and yellow staining of the alveolar hyaline membranes as a function of survival duration in both groups. Bilirubin staining of tissue is apparently a generalized phenomenon, most recognized in the central nervous system as kernicterus. Failure to maintain the impermeability of the cell membrane coupled with regional differences in blood flow would best explain bilirubin distribution. In contrast, the degree of bilirubin staining of alveolar hyaline membranes is time related in kernicteric and control infants.

UI MeSH Term Description Entries
D007231 Infant, Newborn An infant during the first 28 days after birth. Neonate,Newborns,Infants, Newborn,Neonates,Newborn,Newborn Infant,Newborn Infants
D007647 Kernicterus A term used pathologically to describe BILIRUBIN staining of the BASAL GANGLIA; BRAIN STEM; and CEREBELLUM and clinically to describe a syndrome associated with HYPERBILIRUBINEMIA. Clinical features include athetosis, MUSCLE SPASTICITY or hypotonia, impaired vertical gaze, and DEAFNESS. Nonconjugated bilirubin enters the brain and acts as a neurotoxin, often in association with conditions that impair the BLOOD-BRAIN BARRIER (e.g., SEPSIS). This condition occurs primarily in neonates (INFANT, NEWBORN), but may rarely occur in adults.

D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon
D001923 Brain Chemistry Changes in the amounts of various chemicals (neurotransmitters, receptors, enzymes, and other metabolites) specific to the area of the central nervous system contained within the head. These are monitored over time, during sensory stimulation, or under different disease states. Chemistry, Brain,Brain Chemistries,Chemistries, Brain

D006932 Hyperbilirubinemia A condition characterized by an abnormal increase of BILIRUBIN in the blood, which may result in JAUNDICE. Bilirubin, a breakdown product of HEME, is normally excreted in the BILE or further catabolized before excretion in the urine. Bilirubinemia,Bilirubinemias,Hyperbilirubinemias
