Two septic transfusion reactions presenting as transfusion-related acute lung injury from a split plateletpheresis unit

TL;DRAbstract

Our cases highlight the importance of vigilant investigation in patients suspected of transfusion-related acute lung injury, as septic transfusions are easily missed and may mimic or coexist with transfusion-related acute lung injury. Sepsis should be strongly considered whenever clinical features such as hypotension, leucopenia, and fever are noted in patients with suspected transfusion-related acute lung injury. In comparison to patients receiving red blood cells or plasma, platelet transfusion recipients are at a greater risk for sepsis from a contaminated unit. Patients developing sepsis from a contaminated blood product may meet the clinical definition of transfusion-related acute lung injury. In such cases, if the clinical syndrome is attributed solely to transfusion-related acute lung injury and bacterial sepsis is not suspected, the correct diagnosis may be missed or delayed. Consequently, appropriate treatment for sepsis would also be delayed or not provided and likely result
