RESUMO
BACKGROUND: Antibody-mediated transfusion-related acute lung injury (TRALI) is caused by donor HLA or HNA antibodies in plasma-containing products. In the Netherlands 55,000 units of solvent/detergent plasma (SDP), a pooled plasma product, are transfused yearly. It's produced by combining plasma from hundreds of donors, diluting harmful antibodies. Due to a lack of reported cases following implementation, some have labeled SDP as "TRALI safe". STUDY DESIGN AND METHODS: Pulmonary transfusion reactions involving SDP reported to the Dutch national hemovigilance network in 2016-2019 were reviewed. Reporting hospitals were contacted for additional information, cases with TRALI and imputability definite, probable, or possible were included and informed consent was sought. RESULTS: A total of three TRALI and nine TACO cases were reported involving SDP. The imputability of one TRALI case was revised from possible to unlikely and excluded; in one case no informed consent was obtained. We present a case description of TRALI following SDP transfusion in a 69-year-old male, 3 days following endovascular aortic aneurysm repair. The patient received one unit of SDP to correct a heparin-induced coagulopathy, prior to removal of a spinal catheter post-operatively. Within five hours he developed hypoxemic respiratory failure requiring intubation, hypotension, bilateral chest infiltrates, and leucopenia. The patient made a full recovery. CONCLUSION: This case of TRALI, following transfusion of a single unit of SDP to a patient without ARDS risk factors, demonstrates that TRALI can occur with this product. Clinicians should remain vigilant and continue to report suspected cases, to help further understanding of SDP-associated TRALI.
