Hyperbilirubinaemia - Predominantly Unconjugated

  1. Overproduction
    • haemolysis
    • reabsorption of haematoma
    • ineffective erythropoeisis
  2. Decreased hepatic uptake
    • sepsis
    • prolonged fasting
    • RV failure
    • drugs - rifampicin, probenecid
  3. Decreased conjugation
    • hepatocellular disease - hepatitis, cirrhosis
    • sepsis
    • drugs - chloramphenicol
    • inherited glucuronyl transferase deficiency
      • Gilbert's syndrome - actually ligandin deficiency
      • Crigler-Najjar - types II & I

Hyperbilirubinaemia - Predominantly Conjugated

  1. Biliary obstruction
    • biliary cirrhosis - primary | secondary
    • sclerosing cholangitis
    • extrahepatic obstruction - stone, tumour, stricture
  2. Impaired hepatic excretion
    • sepsis
    • post-operative state
    • hepatocellular disease
      • hepatitis - viral, ischaemic, drug-induced
      • cirrhosis
    • drug-induced cholestasis - OCP, methyltestosterone
    • inherited disorders
      • Dubin-Johnson, Rotor syndrome
      • benign familial cholestasis
    • cholestasis of pregnancy
