n. fld>(Med.) Shock resulting from anaphylaxis{ 2 }. It is a severe form of physiological shock, often having a fatal outcome, and is caused by an extreme immunological reaction to antigens. It is characterized by smooth muscle contraction and capillary dilation throughout the body, initiated by antibodies of the IgE class. It is usually seen when an antigen to which a person has become hypersensitized is injected intravenously or subcutaneously. It is also called generalyzed anaphylaxis or systemic anaphylaxis, and sometimes anaphylaxis. [ Stedman ] [ PJC + AS ]

2. (Med.) An immediate but transient systemic reaction to an antigenic substance to which a person has become hypersensitized; it is characterized by the contraction of smooth muscle and capillary dilation. [ Stedman ] [ PJC + AS ]

The cascade of events is triggered by binding of the foreign antigen to immunoglobulin E and release of mediators such as histamine, bradykinin, serotonin, and slow-reacting substance from mast cells. It involves more than one organ system. The most commonly involved organs are skin, cardiovascular, respiratory and gastrointestinal systems. Anaphylaxis is manifested by a range of signs and symptoms including pruritus, urticaria, itching, dyspnea, abdominal pain and cardiovascular collapse (shock). A severe form of the reaction is called anaphylactic shock. [ Stedman ] [ PJC + AS ]
