Abstract

Non-febrile non-haemolytic transfusion reactions (NHTR) after platelet substitution vary from severe (anaphylactic shock) to mild (urticaria) forms. Although the symptoms of these immediate-type hypersensitivity reactions are well documented, little is known about their pathophysiology. We therefore examined sera from patients suffering from different forms of NHTR regarding total serum IgE, specific IgE antibodies and complement activity. Our results show that specific IgE antibodies in the recipients' sera were clearly associated with immediate-type hypersensitivity NHTR and conclude that atopic patients have a higher risk of suffering from these forms of transfusion reactions than non-atopic patients. Allergy diagnostic for patients who require platelet transfusions should be considered in case of multiple platelet substitution.

Anaphylaxis

Anaphylaxis is a serious allergic reaction that is rapid in onset and may cause death.

Atopic Dermatitis

Atopic dermatitis is a chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
