Detection of specific immunoglobulin E antibodies toward common airborne allergens, peanut, wheat, and latex in solvent/detergent-treated pooled plasma

摘要

BACKGROUND: Allergic transfusion reactions (ATRs) present with a broad range of symptoms probably caused by mediators released from mast cells and basophil granulocytes upon activation. Passive immunoglobulin (Ig)E sensitization may yield clinical symptoms and positive allergy tests. Unexpected findings of IgE antibodies in pooled solvent/detergent (S/D)-treated plasma (Octaplas, Octapharma) during routine analysis initiated an investigation of serum proteins.
