The Importance of Allergy Immunology
Allergy immunology refers to the study of all the reactions of the immune system during allergy. As it is already known, allergies are triggered by certain elements related to the immune system. Knowing the fact that the immune system is implied helps people to distinguish allergy from cold, for example.

In a particular case, knowing this aids people to make the difference between peanut allergy and peanut intolerance. In intolerance cases, whether they relate to milk, peanuts or other foods, the symptoms are mild are often different from the ones of the allergies. In both these situations, however, the reactions can be avoided by staying away from the substances that provoke them.

First of all, allergy immunology studies the role of histamine and lgE. These two chemical substances are set free into the body soon after making contact with the allergens. Allergens, such as pollen, mold and mite, are inhaled. The others, that include milk, peanuts and certain other foods, trigger the allergic reaction as soon as they are consumed. On the other hand, latex allergy appears after making contact with products that contain natural rubber.

In all these cases, the elements that are considered allergens are in fact proteins. These are mistaken by the body with dangerous intruders. According to the allergy immunology studies that have been made, when the intruders are detected, the immune system releases histamine and lgE. While the first one is responsible for symptoms such as skin itch and watery eyes, the latter determines the appearance of the symptoms related to the respiratory tract. In consequence, lgE is the cause of allergy asthma and also the cause of wheezing, lung congestion, coughing, and rapid breathing or in some cases, shortness of breath.

The symptoms and even more, the severity of the symptoms differ from one person to another. This is explained by the fact that the immune system is different between the patients. Because of this, the treatment is also diverse, as people with less severe symptoms will utilize certain medication. Most frequently, doctors prescribe antihistamines.

 As allergy immunology studies show, this type of medication is able to neutralize the antibody. The antihistamines are available as pills, nasal sprays and eye drops. If antihistamines prove to be inefficient, then people are recommended to try immunotherapy. This solution is also recommended if the antihistamines are efficient, but have serious side-effects. The allergy immunology studies also reveal the fact that children are able to avoid allergy asthma if they use immunotherapy.
