Allergy immunotherapy
|
|
Allergy immunotherapyStimulation of the immune system with gradually increasing doses of the substances to which a person is allergic. The aim is to modify or stop the allergy by reducing the strength of the IgE response. This form of treatment is very effective for allergies to pollen, mites, animal dander, and especially stinging insects. Allergy immunotherapy usually takes six months to a year to become effective, and injections are usually required for three to five years.
RELATED TERMS--------------------------------------
Immune
Resistant to a particular disease.
Allergy
A major defense mounted by the body's immune system against normally harmless substances, or allergens, such as chemicals in pollen, food, bee stings, animal dander, or dust. An allergic reaction is the body's strong reaction to these substances in a person who is sensitive to them. Reactions range from mild to severe, and may include sneezing, a rash, or difficulty breathing (which can be fatal).
Allergies
Altered reactivity to an antigen, which can result in pathologic reactions upon subsequent exposure to that particular antigen.
Pollen
Pollen is the male fertilising agent of flowering plants, grasses, trees and weeds.
Dander
Tiny scales shed from human or animal skin or hair. Dander floats in the air, settles on surfaces and makes up much household dust. Cat dander is a classic cause of allergic reactions.
Immunotherapy
Stimulating the body's natural defense system to attack and destroy cancers.

Allergic contact dermatitis
A red, itchy, weepy reaction where the skin has come into contact with a substance that the immune system recognizes as foreign, such as poison ivy, poison oak or poison sumac or certain preservatives in creams and lotions.

The ultimate test for the diagnosis of Churg-Straus syndrome is a biopsy of involved tissue. Treatment of Churg-Strauss syndrome involves stopping inflammation and suppressing the immune system.

"One of the U.S. National Institutes of Health (NIH), the mission of the NIAID is ""to support and conduct research and research training (that) strives to understand, treat, and ultimately prevent the myriad infectious, immunologic, and allergic diseases that threaten millions of human lives."" Immunology figures into this statement presumably because it is the common foundation for infectious diseases and allergy."
Allergy desensitization
"Stimulation of the immune system with gradually increasing doses of the substances to which a person is allergic, the aim being to modify or stop the allergy ""war"" (by reducing the strength of the IgE and its effect on the mast cells). This form of treatment is very effective for allergies to pollen, mites, cats, and especially stinging insects (e.g., bees, hornets, yellow jackets, wasps, velvet ants, fire ants). Allergy immunotherapy usually takes 6 months to a year to become effective and injections (""shots"") are usually required for 3-5 years."
Allergy scratch test
Test done on the skin to identify the allergy substance (the allergen) that is the trigger for an allergic reaction. A small amount of the suspected allergy-provoking substance is placed on the skin. The skin is then gently scratched through the small drop with a special sterile needle. If the skin reddens and, more importantly, if it swells, then the test is read as positive and allergy to that substance is considered probable.

Allergy to cockroaches

Allergy, cow milk
"Casein and whey are the two major proteins of human milk and most milk-based formulas. Some (less than 8% of) infants have a true allergy to the cow proteins that are in milk-based formulas. Infants with true cow milk allergy can develop abdominal pain, diarrhea, rectal bleeding, skin rash, and wheezing when given milk- based formulas. These symptoms will disappear as soon milk- based formula is removed from the diet. (Allergy to cow milk protein is different from lactose intolerance). The treatment of cow milk protein allergy involves using formulas that contain no cow milk, or using formulas that contain ""predigested"" casein and whey proteins. The predigesting process breaks the whole proteins into smaller pieces or into amino acids. The amino acids and smaller protein pieces are non-allergenic (do not cause allergy). Soy protein formulas contain no cow milk, and are reasonable alternatives for infants with true cow milk allergy. However, some infants have allergy to both cow milk and soy proteins. These infants require a formula in which the cow milk protein (casein) has been ""predigested"" and specific amino acids added to provide a formula that can provide proper nutrition.
