Analysis of leucocyte antibodies, cytokines, lysophospholipids and cell microparticles in blood components implicated in post-transfusion reactions with dyspnoea

Background and Objectives Post‐transfusion reactions with dyspnoea (PTR) are major causes of morbidity and death after blood transfusion. Transfusion‐related acute lung injury (TRALI) and transfusion‐associated circulatory overload (TACO) are most dangerous, while transfusion‐associated dyspnoea (TA...

Description
Summary:Background and Objectives Post‐transfusion reactions with dyspnoea (PTR) are major causes of morbidity and death after blood transfusion. Transfusion‐related acute lung injury (TRALI) and transfusion‐associated circulatory overload (TACO) are most dangerous, while transfusion‐associated dyspnoea (TAD) is a milder respiratory distress. We investigated blood components for immune and non‐immune factors implicated in PTR. Material and Methods We analysed 464 blood components (RBCs, PLTs, L‐PLTs, FFP) transfused to 271 patients with PTR. Blood components were evaluated for 1/antileucocyte antibodies, 2/cytokines: IL‐1β, IL‐6, IL‐8, TNF‐α, sCD40L, 3/lysophosphatidylcholines (LysoPCs), 4/microparticles (MPs) shed from plateletes (PMPs), erythrocytes (EMPs) and leucocytes (LMPs). Results Anti‐HLA class I/II antibodies or granulocyte‐reactive anti‐HLA antibodies were detected in 18·2% of blood components (RBC and FFP) transfused to TRALI and in 0·5% of FFP transfused to TAD cases. Cytokines and LysoPCs concentrations in blood components transfused to PTR patients did not exceed those in blood components transfused to patients with no PTR. Only EMPs percentage in RBCs transfused to patients with TRALI was significantly higher (P < 0·05) than in RBCs transfused to patients with no PTR. Conclusion Immune character of PTR was confirmed mainly in 1/5 TRALI cases. Among non‐immune factors, only MPs released from stored RBCs are suggested as potential mediators of TRALI. Our results require further observations in a more numerous and better defined group of patients.
