	eMedicine - Anaphylaxis : Article by Richard S Krause
		The true incidence of anaphylaxis is unknown, partly because of the lack of a precise definition of the syndrome.
		Anaphylaxis due to foods may be an underrecognized cause of sudden death and an unappreciated cause of diagnosed anaphylaxis.
		Corticosteroids are used in anaphylaxis primarily to decrease the incidence and severity of delayed or biphasic reactions.

	A Practical Guide to Anaphylaxis - October 1, 2003 - American Family Physician
		Anaphylaxis is a life-threatening reaction with respiratory, cardiovascular, cutaneous, or gastrointestinal manifestations resulting from exposure to an offending agent, usually a food, insect sting, medication, or physical factor.
		Prompt treatment of anaphylaxis is critical, with subcutaneous or intramuscular epinephrine and intravenous fluids remaining the mainstay of management.
		If the diagnosis of anaphylaxis is not clear, laboratory evaluation can include plasma histamine levels, which rise as soon as five to 10 minutes after onset but remain elevated for only 30 to 60 minutes.

	Anaphylaxis
		Anaphylaxis is a type of allergic reaction, in which the immune system responds to otherwise harmless substances from the environment.
		In anaphylaxis, the dramatic response is due both to extreme hypersensivity to the allergen and its usually systemic distribution.
		Anaphylaxis is diagnosed based on the rapid development of symptoms in response to a suspect allergen.

	Anaphylaxis - Life-threatening allergy
		Anaphylaxis is the word used for serious and rapid allergic reactions usually involving more than one part of the body which, if severe enough, can kill.
		Anaphylaxis has become an important issue in medicine and for the increased numbers of people who have had an attack of anaphylaxis.
		Anaphylaxis happens when the body makes the wrong kinds of antibody, a kind called immunoglobulin E (IgE for short) to protein in our food or to something like a drug.

	Anaphylaxis (Severe Allergic Reaction) Symptoms, Causes, Diagnosis, Treatment, and Prevention on MedicineNet.com
		Anaphylaxis refers to a rapidly developing and serious allergic reaction that affects a number of different areas of the body at one time.
		Anaphylaxis is often triggered by substances that are injected or ingested and thereby gain access into the blood stream.
		Although severe cases of anaphylaxis can occur within seconds or minutes of exposure and be fatal if untreated, many reactions are milder and can be ended with prompt medical therapy.

	AAAAI - Patients & Consumers Center: Tips to Remember: What is anaphylaxis?
		Anaphylaxis can occur in some people after they are exposed to a substance to which they are severely allergic.
		Anaphylaxis is triggered the same way other allergies are: the immune system—which serves as the body's defense against potentially dangerous substances such as germs—overreacts to a harmless substance (an allergen) and in that process can damage the body.
		Anaphylaxis is a “systemic reaction,” which means that various parts of the body are affected that are a distance from the allergen's initial entry site (e.g., a sting site for insects or the stomach for foods).

	InteliHealth:
		Anaphylaxis is a severe, sometimes life-threatening, allergic reaction that occurs within minutes of exposure an allergy-causing substance (allergen).
		Symptoms of anaphylaxis usually occur within seconds to minutes of exposure to the allergen and range from mild to very severe.
		A person who has had anaphylaxis is at risk of future severe reactions if he or she is exposed again to the same allergen.

	Anaphylaxis - ACAAI
		Anaphylaxis is a rare but severe allergic reaction. It occurs suddenly, can worsen quickly and can be deadly. Anaphylaxis happens after being exposed to a triggering agent. The agent leads to the release of normal body chemicals such as histamine that cause allergy symptoms.
		The symptoms and course of anaphylaxis can be quite different from one person to the next. The early symptoms may be mild: a runny nose, a skin rash or a "strange feeling." These symptoms can quickly become more serious:
		Penicillin and related antibiotics are the most common medicines that cause anaphylaxis. Many other medicines also can cause anaphylaxis. A very similar problem can happen after taking aspirin or a related medicine such as ibuprofen. To prevent trouble in the future, tell your doctors, nurses, pharmacists and dentists about your medicine allergies.

	Anaphylaxis
		Anaphylaxis is a serious allergic reaction that is rapid in onset and may cause death.
		A recent study showed that teens with food allergy and asthma appear to be at the highest risk for a reaction, because they are more likely to dine away from home, are less likely to carry medications, and may ignore or not recognize symptoms.
		Anaphylaxis is highly likely to occur when any ONE of the following happens within minutes to hours after ingestion of the food allergen:

	Allergic Diseases Resource Center: Anaphylaxis
		Anaphylaxis is an acute, potentially life-threatening hypersensitivity reaction, involving the release of mediators from mast cells, basophils and recruited inflammatory cells.
		Anaphylaxis is defined by a number of signs and symptoms, alone or in combination, which occur within minutes, or up to a few hours, after exposure to a provoking agent.
		Anaphylaxis to muscle relaxants occurs in approximately 1 in 4,500 of general anesthesia, with fatalities occurring in 6% of these cases.

	Anaphylaxis
		If triggers of anaphylaxis can be identified by history and confirmed by diagnostic testing, then patients identified as at risk for anaphylactic reactions should be prescribed life-saving rescue medications that can be administered in the field and be given specific instructions to seek immediate emergency medical evaluation if symptoms develop.
		The clinical symptoms of anaphylaxis derive from the proinflammatory and vasoactive mediators (Table 2) released by the sudden and overwhelming degranulation of mast cells and basophils.
		Egg-allergic children are not at increased risk of anaphylaxis with the measles-mumps-rubella vaccine, as sensitivity to this vaccine is thought to be triggered by sensitivity to gelatin.

		Anaphylaxis is a life-threatening type of allergic reaction.
		Anaphylaxis is an acute systemic (whole body) type of allergic reaction.
		This is usually from a toxic or idiosyncratic reaction rather than the "immune system" mechanism that occurs with "true" anaphylaxis, though the symptoms, risk for complications without treatment, and therapy are the same.

	Anaphylaxis Treatment Guidelines from EpiPen®
		The mainstays of treating anaphylaxis are avoidance of the allergen when possible and emergency administration of epinephrine when necessary.
		Once anaphylaxis has begun, the treatment of choice is an immediate injection of epinephrine, sometimes called adrenaline, which is effective for 10 to 15 minutes, followed by emergency medical attention.
		Since there is no way to predict the severity of a reaction, and because anaphylaxis can progress so rapidly, waiting for the paramedics or ER staff to administer epinephrine may greatly increase the risk of death.

	HON Allergy Glossary Anaphylaxis
		Anaphylaxis is a medical emergency which involves an acute systemic (affecting the entire body) allergic reaction.
		This causes cells to release histamine, which in turn causes the airways to constrict (causing difficulting in breathing), blood vessels to relax (lowering blood pressure) and the walls of the blood vessels to leak fluid (resulting in hives and swelling).
		Anaphylaxis occurs immediately or at most within 2 hours of exposure to the allergen.

	Anaphylaxis asthma
		A lower association between asthma and anaphylaxis was reported by Brown, McKinnon and Chu who reported that 23% of cases of anaphylaxis presenting to an emergency room in Australia were associated with asthma.
		Moreover the commonest cause of anaphylaxis in that study was drugs, a sensitivity that is not necessarily associated with atopy.
		In summary, from the studies cited relating asthma to the severity of anaphylaxis, and the mechanisms outlined, it is important to manage asthma so that it is under control in the food-allergic patient.

	Anaphylaxis
		Anaphylaxis to injected antigen is more frequent, severe, and rapid in onset.
		Biochemically, anaphylaxis is related to the degranulation of mast cells and basophils with the subsequent release of chemical mediators, which are responsible for the symptoms.
		In this case, the differential diagnosis, between anaphylaxis and other causes of shock, must be made immediately. Vasodepressor reactions are probably the events most commonly confused with anaphylaxis.
