Abstract

The term hypersensitiveness refers to the adaptive immune response occurring in an exaggerated or uncommon way. Reactions to hypersensitiveness are protecting immune responses that frequently result in inflammation reactions and tissue damage. Type I hypersensitiveness is also called anaphylaxis and many compounds may cause the reaction. Anaphylaxis is the systemic reaction of immediate hypersensitiveness characterized by edema in several tissues and a fall in blood pressure posterior to a vasodilatation process; the fall in blood pressure is called anaphylactic shock. The anaphylaxis diagnosis is established by the presence of specific IgE for determined allergens and evidences their participation in the induction of symptoms. The administration of adrenalin is a treatment against anaphylaxis which causes bronchodilatation and vasoconstriction. Current review furnishes information to professionals, researchers and the public on physiopathology, its causes, diagnosis and treatment for anaphylaxis which is frequently fatal.
