Summary
Anaphylaxis is a life-threatening allergic syndrome characterized by multiorgan involvement and rapid onset, which can lead to life-threatening airway compromise and cardiovascular collapse. Anaphylaxis is an IgE-mediated (Type I or immediate) hypersensitivity reaction, resulting in mast cell degranulation and release of mediators including histamine and cytokines. The release of these chemical mediators results in a constellation of symptoms within 30 minutes of exposure.
