Alcohol-induced Liver Failure
  • hyperbilirubinaemia, raised LFTs
  • hypoalbuminaemia
  • coagulopathy and mild thrombocytopaenia
  • low-normal creatinine/urea
  • mild hyponatraemia

 

Alcoholic Hepatitis

  1. ↑ AST:ALT ratio > 2.0 (R:1.5-2.0)
  2. ↑↑ GGT disproportionately
  3. Hyperbilirubinaemia

 

Cirrhosis

  1. Hyperbilirubinaemia
  2. Mild elevation of AST > ALT
  3. Hypoalbuminaemia
  4. Hyperglobulinaemia
  5. ↑ INR/APTT
  6. Low Na+, K+, Mg++ ∝ dilution & 2° hyperaldosteronism
  7. Low urea, Ca++
  8. High NH3, glucose
  9. ABG → compensated respiratory alkalosis

 

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
  • 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
