Definition of anaphylaxis and criteria for diagnosis
Anaphylaxis is a severe, potentially fatal, systemic allergic reaction that occurs suddenly after contact with an allergy-causing substance. Participants at the symposium agreed that a brief, broad definition of anaphylaxis that reflected its course and potential severity would be most useful to both the medical and lay community and recommended the following: “Anaphylaxis is a serious allergic reaction that is rapid in onset and may cause death.”
To identify individuals experiencing such a
Management of anaphylaxis
As with the treatment of any critically ill patient, the treatment of anaphylaxis begins with a rapid assessment and maintenance of airway, breathing, and circulation. When a patient fulfills any of the 3 criteria of anaphylaxis outlined above, the patient should receive epinephrine immediately because epinephrine is the treatment of choice in anaphylaxis. There undoubtedly will be patients who present with symptoms not yet fulfilling the criteria of anaphylaxis yet in whom it would be
Research needs
The investigation of anaphylaxis has been impeded by the lack of universally accepted diagnostic criteria and the absence of reliable laboratory biomarkers to confirm the clinical impression. This in turn has thwarted efforts to ascertain the incidence and outcome of anaphylaxis in various populations, to determine the most effective forms of therapy, to identify patients at risk for life-threatening anaphylaxis, and to elucidate the basic immunologic and pathogenic mechanisms responsible for
