-==Overview==
+==[[Anaphylaxis overview|Overview]]==
-'''Anaphylaxis''' is an [[acute (medical)|acute]] [[circulation|systemic]] (multi-system) and severe Type I Hypersensitivity [[allergy|allergic]] reaction in humans and other [[mammal]]s.  The term comes from the Greek words ''ana'' (against) and ''phylaxis'' (protection).<ref>"Anaphylaxis." Etymology. ''Oxford English Dictionary''. http://dictionary.oed.com.</ref> Anaphylaxis occurs when a person or animal is exposed to a trigger substance, called an ''[[allergen]],'' to which they have already become sensitized. Minute amounts of allergens may cause a life-threatening anaphylactic reaction. Anaphylaxis may occur after ingestion, skin contact, injection of an allergen or, in rare cases, inhalation.<ref>"Anaphylaxis." Health. 17 January 2002 . AllRefer.com . 29 Jan 2007 <http://health.allrefer.com/health/anaphylaxis-info.html>.</ref>
+==[[Anaphylaxis historical perspective|Historical Perspective]]==
-'''Anaphylactic shock''', the most severe type of anaphylaxis, occurs when an allergic response triggers a quick release from [[mast cell]]s of large quantities of [[immunology|immunological]] mediators ([[histamine]]s, [[prostaglandin]]s, [[leukotriene]]s) leading to systemic [[vasodilation]] (associated with a sudden drop in blood pressure) and [[edema]] of [[bronchial]] [[mucosa]] (resulting in [[bronchoconstriction]] and difficulty breathing).  Anaphylactic shock can lead to death in a matter of minutes if left untreated.
+==[[Anaphylaxis classification|Classification]]==
-Researchers typically distinguish between "'''true anaphylaxis'''" and "'''pseudo-anaphylaxis'''."  The symptoms, treatment, and risk of death are identical, but "true" anaphylaxis is always caused directly by [[degranulation]] of [[mast cell]]s or basophils that is mediated by [[immunoglobulin]] E (IgE), and pseudo-anaphylaxis occurs due to all other causes.  The distinction is only important for researchers who are studying mechanisms of allergic reactions. Due to the word "pseudo", it may frustrate patients who feel they are being told that a life-threatening allergic reaction isn't "real".

-The [[Asthma and Allergy Foundation of America]] advises patients prone to anaphylaxis to have an "allergy action plan" on file at school, home, or in their office to aid others in case of an anaphylactic emergency, and provides a free

-[http://www.aafa.org/display.cfm?id=4&sub=81&cont=392 "plan"] form anyone can print. Action plans are considered essential to quality emergency care. Many authorities advocate immunotherapy to prevent future episodes of anaphylaxis.[http://www.acaai.org/public/patients/factSheet.htm "allergy fact sheet"] Immunotherapy with Hymenoptera venoms is especially effective and widely used throughout the world and is accepted as an effective treatment for most patients with allergy to bees, wasps, hornets, yellow jackets, white faced hornets, and fire ants.
