Anaphylaxis in Schools 3rd Edition

Idiopathic reaction: a reaction that results from an unknown cause.
Appendix K
Immune system: the infection-fighting part of the body; in allergic individuals, harmless substances
trigger the immune system to “fight”.
Immunology: the science and study of the immune system.
Immunotherapy: a series of desensitizing injections (allergy shots) prescribed by an allergist that may
be used to protect against allergy – extremely small amounts of an allergen, such as stinging insect
venom, are gradually given in increasing dosages until a tolerance develops – not available for all
allergens.
Oral immunotherapy: an experimental desensitization treatment for food allergy. With this treatment,
extremely small amounts of an allergen are gradually given in increasing dosages until a tolerance
develops (the patient eats the food to which they are allergic). Not yet available as a routine
treatment option.
Proteins: complex chemical substances made of amino acids; proteins are essential constituents of all
living cells.
Protocol: a written plan to follow for management of a condition in case of an emergency; useful tool
for schools, day cares, summer camps, etc.
Sensitization: an allergic response to an allergen that results in specific IgE antibodies being produced
that allow allergic reactions whenever subsequent exposure occurs.
Skin tests: The placement of a small, dilute amount of allergen onto the skin of the arm or back,
through which the skin is pricked, or the injection of a small, dilute amount of allergen under the skin.
If the patient is allergic to that substance, a small raised area surrounded by redness will appear at the
test site within 15 minutes.
Systemic reaction: An allergic reaction that affects the whole body or body system, as opposed to a
local reaction that is confined to the immediate area of exposure.
Triggers: Factors that can provoke allergic reactions or asthma episodes, including allergens
and irritants.
Urticaria (see Hives)
