Endomyocardial biopsies (EMB) and transbronchial lung biopsies (TBLB) are crucial for diagnosing allograft rejection after heart and lung transplants. Lymphocyte infiltration severity correlates with rejection, aiding patient management.

Area of Science:

  • Cardiovascular Pathology
  • Pulmonary Pathology
  • Transplantation Immunology

Context:

  • Investigating pathologic features of cardiac and pulmonary allografts post-transplantation.
  • Utilizing endomyocardial biopsies (EMB) and transbronchial lung biopsies (TBLB) in clinical practice.
  • Examining autopsy findings in heart and combined heart-lung transplant recipients.

Purpose:

  • To correlate biopsy findings with allograft rejection severity.
  • To assess the utility of EMB and TBLB in diagnosing acute allograft rejection.
  • To identify pathologic markers associated with transplant outcomes.

Summary:

  • Biopsy analysis revealed that interstitial and perivascular lymphocyte infiltration directly correlates with the presence and severity of allograft rejection.

  • Parenchymal injury was observed as a potential concurrent sign of rejection.
  • One patient experienced fatal acute rejection and allograft coronary disease post-cardiac transplant; another died from thromboembolism post-combined transplant.
  • Recurrent pulmonary sarcoidosis was detected in a donor lung via TBLB 11 and 13 months post-single lung transplant.
  • EMB and TBLB proved valuable for diagnosing acute allograft rejection following heart and lung transplantation.

    • Impact:

    • Confirms the diagnostic value of EMB and TBLB for acute allograft rejection.
    • Highlights the relationship between lymphocyte infiltration and rejection severity.
    • Provides insights into potential complications like allograft coronary disease and recurrent sarcoidosis.
