What is a specific immunotherapy?
Specific immunotherapy (SIT) is a treatment used to help people suffering from allergies. Allergy is an exaggerated reaction of the immune system to substances such as pollen, which is harmless to the body, and specific immunotherapy is the technique of immune training to get less allergen. This method of reducing the severity of allergies requires that the affected person be exposed to a small amount of allergen by injections or oral drops. Specific immunotherapy is also known as hyposensitization or immunotherapy specific to allergen.
allergies are abnormal reactions to substances such as peanuts, dust and pollen. Some people suffer from allergic reactions to one or more of these substances that are so serious that this affects the quality of life for a person. Astma is one of the examples of allergy that is a potentially life -threatening life, and a state called anaphylactic shock can also kill people with allergies on substances such as shellfish or nuts. The exact way in which allergies work,They are caused by the components of the immune system that respond poorly to allergens.
Normally, the immune system is useful in combating infection, as cells and antibodies in the body recognize and destroy various invasive pathogens such as bacteria or viruses. In general, antibodies and immune cells record the presence of an attacker and send signals to the body to help kill and break the attacker. These signals include molecules that act as instructions on the production of swelling, redness and pain in the affected area.
When a person has an allergy, these signals create symptoms that are not useful for health and actually damage health. At the slight end of the scale, allergies can produce symptoms such as red eyes, increase tears or skin rashes. It can be difficult to cause serious allergic reactions' tissue is so much swelling, or to limit the lungs so that the person can not breathe. Anaphylactic shock can tif influence the heart's ability to defeat normally.
Although allergens cause side effects in those affected by allergies, scientists have found that the presentation of the immune system of the allergen can help train the immune system to respond more normal to allergen. In specific immunotherapy, accurate allergens from a given substance such as peanut proteins are packed in a product of a similar vaccine. Usually specific immunotherapy requires the allergen to be injected into the body or absorbed into the body of drops under the tongue.
In general, the body adapts to a regular exposure to the allergen with a reduced level of immune response, as it has learned to solve the allergen less over the peak, so patients usually have to have a prolonged course of specific immunotherapy over time. The risk of serious allergic reactions still exists with immunotherapy allergens and some people do not respond to treatment. However, some people found out after treatment that their allergies have disappeared.
