Popis: Exercise-induced anaphylaxis is a mast cell dependent reaction, which is induced by allergen exposure in combination with physical activity. Typically, the reaction occurs within 2 hours after allergen exposure followed by physical activity. Not only food allergens but all kinds of allergens including drugs can induce this form of anaphylaxis. The clinical symptoms of exercise-induced anaphylaxis are the same as in any other type of anaphylaxis. Thus not only the skin and mucosa but also other organ systems like the lungs, cardiovascular system and gastrointestinal tract can be affected. The diagnostic work up should cover a detailed clinical history including the assessment of symptoms and possible trigger factors including suspected allergens. Besides classical allergy diagnostics like skin prick tests and specific IgE determination, tryptase should be measured for the differential diagnosis to exclude mast cell dependent diseases. The diagnosis of exercise-induced anaphylaxis is made by the means of a double-blind placebo-controlled provocation test. Both, a sufficient amount of allergen and of physical activity must be achieved for a valid test. After the diagnosis is made, patients should be extensively counseled and provided with an emergency kit including an epinephrine auto injector.
