The term anaphylaxis as used currently means a sudden adverse reaction to a foreign substance, mediated by histamine or other products of cell metabolism and having adverse and potentially lethal immediate effects on the respiratory, cardiovascular, and other systems.1 It includes both immunoglobulin E (IgE)-medi-ated acute or recurrent reactions and anaphylactoid reactions, which simulate acute anaphylaxis clinically but are not caused by IgE-mediated hypersensitivity.
