Summary

This case study documents the first instance of hyperacute rejection in lung transplant recipients, confirmed by a positive lymphocytotoxic crossmatch (LXM). The findings suggest routine LXM for high-risk patients to prevent this severe complication.

Area of Science:

  • Transplantation immunology
  • Pulmonary medicine

Background:

  • Hyperacute rejection is well-documented in other solid organ transplants but not previously in lung transplants.
  • Pre-transplant crossmatch testing is not routinely performed in lung transplantation.

Observation:

  • A lung transplant recipient presented with clinical hyperacute rejection.
  • Histopathology revealed diffuse alveolar damage, neutrophilic infiltrates, and endothelial/epithelial damage.
  • Immunofluorescence showed IgG staining in alveolar spaces, confirming antibody-mediated damage.

Findings:

  • The observed rejection was corroborated by a positive donor-antigen-specific IgG-mediated lymphocytotoxic crossmatch (LXM).
  • The histopathologic and immunofluorescent findings were consistent with hyperacute rejection seen in other organs.

Implications:

  • This case highlights the potential for hyperacute rejection in lung transplantation.
  • Routine lymphocytotoxic crossmatch (LXM) testing is recommended for lung transplant candidates with high panel-reactive antibodies.
  • LXM should be considered whenever feasible to identify and mitigate rejection risk.
