abstract

  • It is unknown the extent to which transfusion-related acute lung injury (TRALI) contributes to primary graft dysfunction (PGD), the leading cause of death after lung transplantation. In this case of suspected transfusion-associated acute bilateral graft injury in a 61-year-old idiopathic pulmonary fibrosis patient, recipient sera from before and after transplantation/transfusion, as well as the sera of 22 of the 24 implicated blood donors, were individually screened by Luminex bead assay for the presence of human leukocyte antigen (HLA) antibodies, with recipient and lung donor HLA typing to explore for cognate relationships. A red-cell-unit donor-source anti-Cw6 antibody, cognate with the HLA type of the recipient, was identified. This is the second reported case of TRALI in the setting of lung transplantation, and the first to show an associated interaction between donor antibodies (in a low-plasma volume product) with recipient leukocytes (rather than graft antigens); therefore, it should be considered in the differential diagnosis of PGD.
