What is anaphylaxis in the body?
The World Allergy Organisation (WAO) defines anaphylaxis as “a serious systemic hypersensitivity reaction that is usually rapid in onset and may cause death. Severe anaphylaxis is characterized by potentially life-threatening compromise in airway, breathing and/or the circulation, and may occur without typical skin features or circulatory shock being present”.1Anaphylaxis thus lies along a spectrum of severity, ranging from mild objective breathing problems (such as mild wheezing) to circulatory “shock” and/or collapse (“anaphylactic shock”). The estimated incidence for anaphylaxis in Europe is 1.5 to 7.9 per 100,000 person-years, with a lifetime prevalence of 1 in 300.2International guidelines concur that the first line treatment of anaphylaxis is intramuscular (IM) adrenaline,3but there is increasing divergence between published guidelines.4This may be due to a lack of high-certainty evidence to support treatment recommendations.5Given the difficulties of undertaking randomised controlled trials in the management of a potentially life-threatening condition, guidelines must therefore be based on the best available research evidence, theory and expert consensus.
