Summary

Centrilobular changes in liver biopsies after transplantation indicate ischemic injury. The presence of hepatocytic ballooning, dropout, and cholestasis together predicts poor outcomes, while central venulitis signals rejection but not necessarily poor survival.

Area of Science:

  • Hepatology
  • Transplant Pathology
  • Gastroenterology

Background:

  • Centrilobular changes in liver biopsies are common after orthotopic liver transplantation (OLT).
  • Understanding these histologic patterns is crucial for accurate diagnosis and prognosis.

Purpose of the Study:

  • To systematically evaluate centrilobular histologic changes in OLT biopsies.
  • To correlate these findings with clinical data and identify potential prognostic criteria.

Main Methods:

  • Review of 110 biopsies with zone 3 pathology from 59 patients undergoing OLT.
  • Correlation of histologic findings (hepatocytic dropout, ballooning, cholestasis, central venulitis) with clinical data.

Main Results:

  • In the early post-OLT period (≤6 months), combinations of hepatocytic dropout, ballooning, and cholestasis were attributed to ischemic/perfusion injury.

  • The presence of all three features (dropout, ballooning, cholestasis) was associated with increased biliary complications, sepsis, and decreased 1-year patient and graft survival.
  • Central venulitis, indicative of acute or chronic rejection, was observed at any time post-OLT and was not a predictor of poor survival.

    • Conclusions:

    • Centrilobular hepatocytic changes in early post-OLT biopsies reflect ischemic/perfusion damage, with all three features predicting poor outcomes.
    • Central venulitis signifies rejection but does not predict graft or patient survival.
    • Histologic evaluation of centrilobular changes aids in refining OLT post-transplant diagnosis and prognosis.
