After febrile reactions to red cell transfusions, which component is best for subsequent transfusions?

• A. Fresh Frozen Plasma
• B. Leukocyte-Reduced Red Cells
• C. Platelet Concentrates
• D. Granulocyte Concentrates

Answer: (B)

Febrile transfusion reactions are often caused by donor white blood cells and the cytokines they release during storage. Removing most leukocytes from blood products before storage—prestorage leukoreduction—significantly lowers the risk of these febrile reactions and also reduces alloimmunization to HLA antigens. Therefore, for subsequent transfusions after such reactions, using leukocyte-reduced red blood cells is the best choice. Fresh Frozen Plasma addresses coagulation factors rather than leukocyte-related reactions. Platelet concentrates and granulocyte concentrates can also provoke febrile or other reactions and are not the preferred option to prevent FNHTR in red cell transfusions; leukoreduced red cells specifically target the mechanism behind these febrile responses.
