Summary

Centrilobular necrosis (CN) in liver allografts after orthotopic liver transplantation (OLT) is a potential indicator of severe, irreversible rejection. Persistent CN is linked to poorer patient prognosis and ductopenic rejection.

Area of Science:

  • Hepatology
  • Transplantation Immunology
  • Pathology

Background:

  • Centrilobular necrosis (CN) is observed in liver allografts post-orthotopic liver transplantation (OLT).
  • The clinical significance and underlying causes of CN require further elucidation.

Purpose of the Study:

  • To investigate the incidence, morphology, clinical course, and prognostic implications of centrilobular necrosis in liver allografts.

Main Methods:

  • A biopsy study of 60 allografts from 53 patients undergoing OLT.
  • Morphological analysis of necrotic lesions and correlation with clinical outcomes, rejection types, and perioperative factors.

Main Results:

  • Prominent CN was found in 18% of analyzed grafts, presenting with varied morphology.

  • Persistent CN correlated with ductopenic (chronic) rejection and a worse patient prognosis.
  • No association was found between CN and rejection arteritis, perioperative factors, or acute rejection episodes.

    • Conclusions:

    • Severe rejection, potentially leading to ductopenia, is the most likely cause of CN.
    • CN in repeated liver allograft biopsies serves as a warning sign for irreversible rejection.
