Overview
When red blood cells die, the heme in their haemoglobin is converted to bilirubin in the spleen and in the hepatocytes in the liver. The bilirubin is processed by the liver, enters bile and is eventually excreted through feces.
Consequently, there are three different classes of causes for jaundice. Pre-hepatic or hemolytic causes, where too many red blood cells are broken down, hepatic causes where the processing of bilirubin in the liver does not function correctly, and post-hepatic or extrahepatic causes, where the removal of bile is disturbed.
Causes
Jaundice may be caused by:
- Unconjugated hyperbilirubinemia:
- Common Causes:
- Increased bilirubin production:
- Extravascular hemolysis
- Extravasation of blood into tissues
- Intravascular hemolysis
- Wilson disease
- Impaired hepatic bilirubin uptake:
- Heart failure
- Portosystemic shunts
- Drugs - Rifampin, Probenecid
- Impaired bilirubin conjugation:
- Crigler-Najjar syndrome types I and II
- Gilbert syndrome
- Ethinyl estradiol
- Liver diseases - chronic hepatitis, advanced cirrhosis
- Increased bilirubin production:
- Less Common Causes:
- Increased bilirubin production:
- Dyserythropoiesis
- Impaired hepatic bilirubin uptake:
- Some patients with Gilbert syndrome
- Drugs - flavaspadic acid, bunamiodyl
- Impaired bilirubin conjugation:
- Neonates
- Hyperthyroidism
- Increased bilirubin production:
- Common Causes:
- Conjugated hyperbilirubinemia:
- Common Causes:
- Intrahepatic cholestasis:
- Viral hepatitis
- Alcoholic hepatitis
- Nonalcoholic steatohepatitis
- Chronic hepatitis
- Primary biliary cholangitis
- Drugs and toxins (eg, alkylated steroids, chlorpromazine, herbal medications [eg, Jamaican bush tea], arsenic)
- Sepsis and hypoperfusion states
- Infiltrative diseases (eg, amyloidosis, lymphoma, sarcoidosis, tuberculosis)
- Pregnancy
- End-stage liver disease
- Extrahepatic cholestasis (biliary obstruction):
- Choledocholithiasis
- Intrinsic and extrinsic tumors (eg, cholangiocarcinoma)
- Primary sclerosing cholangitis
- Acute and chronic pancreatitis
- Strictures after invasive procedures
- Intrahepatic cholestasis:
- Less Common Causes:
- Intrahepatic cholestasis:
- Total parenteral nutrition
- Postoperative cholestasis
- Following organ transplantation
- Hepatic crisis in sickle cell disease
- Extrahepatic cholestasis (biliary obstruction):
- AIDS cholangiopathy
- Certain parasitic infections (eg, Ascaris lumbricoides, liver flukes)
- Defect of canalicular organic anion transport:
- Dubin-Johnson syndrome
- Defect of sinusoidal reuptake of conjugated bilirubin:
- Rotor syndrome
- Intrahepatic cholestasis:
