Chronic Rejection of Transplanted Liver

Definition

  • Consequence of severe chronic immunologic injury to bile duct epithelium (loss of ducts) and endothelium (obliterated arteries)

Alternate/Historical Names

  • Obliterative arteriopathy
  • Foam cell arteriopathy
  • Vanishing bile duct syndrome
  • Ductopenic rejection

Diagnostic Criteria

  • Two types: bile duct loss and obliterative arteriopathy
    • Usually occur together
    • Only one site affected in about 15% of cases
  • Bile duct loss (ductopenia, vanishing bile duct syndrome)
    • At least 50% of portal tracts lack bile ducts
      • Need at least 4-5 complete portal tracts to evaluate
      • Preferably 20 tracts to evaluate
    • Absence of bile ductular proliferation
    • Cholestasis in zone 3 (pericentral)
    • Pericentral hepatocyte ballooning and dropout
    • Due to chronic injury
      • Acute bile duct loss after acute rejection may be reversible
  • Obliterative arteriopathy
    • Requires hepatectomy for diagnosis
      • Occluded arteries due to concentric intimal thickening and lipid rich macrophages
      • Biliary strictures may occur
    • Centrilobular hepatocyte dropout

Supplemental studies

  • Anti-keratin stain to evaluate ductopenia
    • CK7 and AE1 are useful markers because they have low background activity against hepatocytes

Differential Diagnosis

Acute Rejection of Liver Chronic Rejection of Liver
1 week to 1 year post-transplant Presents > 6-12 months post-transplant
Bile duct lymphocytic infiltrate Bile duct loss in at least 50% of portal tracts
No cholestasis unless extensive bile duct damage Centrilobular cholestasis
No hepatocyte swelling Centrilobular hepatocyte swelling
No apoptotic bodies in lobules Scattered apoptotic bodies may be present

Diseases with a significant incidence of recurrence in transplants

  • Autoimmune hepatitis
  • Hepatocellular carcinoma
  • Primary biliary cirrhosis
    • Can be impossible to distinguish from chronic rejection on histology
  • Primary sclerosing cholangitis
  • Viral hepatitis B
  • Viral hepatitis C

Clinical

  • Usually presents >6-12 months post-transplant
  • Initial symptoms may mimic acute rejection
  • Late features are cholestatic
    • Elevated alkaline phosphatase, GGT

Grading / Report

  • Early chronic rejection
    • Loss of bile ducts in 20-50% of portal tracts
    • Dystrophic changes in >50% of remaining bile ducts
    • Often reversible
  • Late chronic rejection
    • >50% of portal tracts lack bile ducts
