Graft versus Host Disease (GVHD) of the Liver

Definition

  • Attack by engrafted hematopoietic cells and their progeny on the host liver

Diagnostic Criteria

  • Early phase
    • Lymphoplasmacytic infiltration of portal tracts
    • Damage to bile duct epithelium
      • Cytoplasmic swelling and vacuolation
      • Enlarged and overlapping nuclei (reactive epithelial atypia)
      • Apoptosis
  • Late phase
    • Loss of bile ducts
    • Increased fibrosis

Supplemental studies

Immunohistology

  • Useful for detection of hepatitis B and other viral diseases

Differential Diagnosis

Chronic viral hepatitis C

  • Dense lymphoid aggregates
  • Interface hepatitis
  • Acidophil bodies

Drug induced damage

  • Chemoirradiation effects last 3-4 weeks
  • Other drugs can have hepatitis or cholestatic picture or granulomas

Primary biliary cirrhosis

  • Can be difficult to distinguish from GVHD
  • Features favoring PBC
    • Granulomas if present
    • Florid bile duct lesions

Venocclusive disease

  • Due to chemotherapy and radiation toxicity
  • Usually presents 3 weeks after therapy
  • Endothelial injury in sinusoids and venules
  • May have fibrin thrombi

Clinical

  • Acute vs. chronic GVHD: clinically 100 day cutoff
    • Poor correlation between pathologic features and clinical definition of acute vs. chronic
  • Acute GVHD
    • Develops 2-6 weeks after allogeneic transplant
    • Primary targets
      • Skin 90%
      • Liver 40-60%
      • GI tract 30-50%
    • Early recognition of GVHD and prompt intervention improves outcome
    • Advanced GVHD easy to diagnose but mortality can be 50%
  • Chronic GVHD
    • Resembles autoimmune connective tissue disorders
    • Mortality is high due to infections promoted by GVHD associated immunodeficiency
    • Target organs more widespread but skin, liver and GI tract play a major role
  • In liver typically presents as obstructive jaundice due to destruction of small intrahepatic bile ducts, similar to primary biliary cirrhosis

Grading

Grade Bile ducts showing epithelial damage
I <25%
II 25-49%
III 50-74%
IV 75-100%
(Not widely performed)
