Clinical InformationClinical

  • Crigler-Najjar Syndrome

    a familial form of congenital hyperbilirubinemia transmitted as an autosomal recessive trait. it is characterized by icterus and brain damage caused by a glucuronyl transferase deficiency in the liver and faulty bilirubin conjugation.

  • Gilbert Disease

    a benign familial disorder, transmitted as an autosomal dominant trait. it is characterized by low-grade chronic hyperbilirubinemia with considerable daily fluctuations of the bilirubin level.

  • 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.

  • Hyperbilirubinemia, Hereditary

    inborn errors of bilirubin metabolism resulting in excessive amounts of bilirubin in the circulating blood, either because of increased bilirubin production or because of delayed clearance of bilirubin from the blood.

  • Hyperbilirubinemia, Neonatal

    accumulation of bilirubin, a breakdown product of heme proteins, in the blood during the first weeks of life. this may lead to neonatal jaundice. the excess bilirubin may exist in the unconjugated (indirect) or the conjugated (direct) form. the condition may be self-limiting (physiological neonatal jaundice) or pathological with toxic levels of bilirubin.

  • Jaundice, Chronic Idiopathic

    a benign, autosomally recessive inherited hyperbilirubinemia characterized by the presence of a dark pigment in the centrilobular region of the liver cells. there is a functional defect in biliary excretion of bilirubin, cholephilic dyes, and porphyrins. affected persons may be asymptomatic or have vague constitutional or gastrointestinal symptoms. the liver may be slightly enlarged, and oral and intravenous cholangiography fails to visualize the biliary tract.

  • Jaundice

    a clinical manifestation of hyperbilirubinemia, characterized by the yellowish staining of the skin; mucous membrane; and sclera. clinical jaundice usually is a sign of liver dysfunction.

  • Jaundice, Neonatal

    yellow discoloration of the skin; mucous membrane; and sclera in the newborn. it is a sign of neonatal hyperbilirubinemia. most cases are transient self-limiting (physiological neonatal jaundice) occurring in the first week of life, but some can be a sign of pathological disorders, particularly liver diseases.

  • Jaundice, Obstructive

    jaundice, the condition with yellowish staining of the skin and mucous membranes, that is due to impaired bile flow in the biliary tract, such as intrahepatic cholestasis, or extrahepatic cholestasis.

  • Weil Disease

    a severe form of leptospirosis, usually caused by leptospira interrogans serovar icterohaemorrhagiae and occasionally other serovars. it is transmitted to humans by the rat and is characterized by hemorrhagic and renal symptoms with accompanying jaundice.

  • Breast Milk Jaundice|Breastmilk Jaundice|Neonatal Jaundice due to Delayed Conjugation from Breast Milk Inhibitors

    jaundice in an otherwise healthy breast-fed newborn. it appears four to seven days after birth, lasts longer than the physiologic jaundice, and there are no identifiable causes.

  • Neonatal Jaundice

    jaundice that appears during the neonatal period. in the majority of cases, it appears in the first week of life and is classified as physiologic due to accelerated destruction of erythrocytes and liver immaturity. in a minority of cases it is classified as non-physiologic, appearing in the first twenty four hours after birth, and is associated with underlying diseases including hemolytic disorders, polycythemia, and cephalohematoma.

  • Neonatal Hyperbilirubinemia

    increased levels of bilirubin in the blood during the neonatal period. in the majority of cases it is seen in the first week of life and usually there is no underlying disease, however, it may also occur in hemolytic diseases, infections, metabolic disorders, and liver abnormalities.

Patient EducationClinical

Jaundice

Jaundice causes your skin and the whites of your eyes to turn yellow. Too much bilirubin causes jaundice. Bilirubin is a yellow chemical in hemoglobin, the substance that carries oxygen in your red blood cells. As red blood cells break down, your body builds new cells to replace them. The old ones are processed by the liver.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
