What are allergens?

The term “allergy” is enough well-known not only by different physicians but by many people all over the world. It is one of its definitions: allergy is a condition of heightened apprehensibility of the person’s organism to one or another substance mostly accompanied by some damages of tissues and development of some specific inflammations. Sometimes is may be one-single allergic reactionto some matters, in other time it may be appeared in view of the strongest sickness with serious consequences. In fact, that allergy is companied by some inflammatory phenomena is known for everybody. But many people don’t know what substances can start up the powerful allergic reactions.They are generally manifested with helping of allergens. It is impossibly the development of several allergic inflammations without these matters. And what are the allergens?

Biological allergens

Biological allergens can be presented in view of microbes, different viruses, fungi, helminthes, serum and vaccinal preparations. The development of various infectious illnesses (such as brucellosis,leprosy, tuberculosis,typhoid feverand many others) is mostly accompanied by hay fever. Such allergy is called the infectious one and the group of diseases called by microbes, fungi or viruses when the allergy plays the main rile in their development is mostly called infectious-allergic one. Usually the microbes and fungi which are often on the skin or in the breathing passage, oral cavity or bowels generally bring to the development of such sicknesses. The allergy treatmentis happened with help of macrolides antibiotics (Erythromycin,Biaxin, Zithromax and many others), some medications from the penicillins’ group (Augmentin, Amoxil, Amoxicillin, Griseofulvin, Ampicillin and so on) or some medical agents with antimicrobial activity (Bactrim, Avelox, Ceclor, Keflex, Cephalexin, Seromycin, Chloramphenicol, Trecator SC, Ciloxan, Gentamicin, Cipro, Zyvox, Furazolidone, Vancomycin, and others).

Officinal allergens

Allergic reaction can be called by practically every preparation. So, the allergic complications under the application of codeine are 1.5%, Bayer ASA Aspirin– 1.9%, sulfonamides – 6.7%, the preparations from the penicillins’ row – till 16%. There are also some allergic complications appeared as answer on the brining in Novocain, vitamin B and many other medicamental remedies. In connection with considerable spreading of antibiotic exactly these medications (in the first place the penicillin) more often call different allergic aftereffects of illness. It is followed to remember that applying of different medical preparations without physician’s prescribing is very dangerous.    

Home allergens

The main role in this category is played by domestic dust which consists of dust fractions from carpets, clothes, furnishing; fungi on the walls in damp rooms; fractions of domestic insects (such as bed bugs, cockroaches, bed mites and others). To this group are related so-called epidermal allergens such as hair, wool, dandruff of animals and many others. In last years it is maximally enlarged the number of allergic reactions on the preparations of household chemistry especially on the powdered detergent, soap, shampoo and so on. The domestic allergens often call the allergic illnesses of respiratory ways (bronchial asthma, allergic bronchitis, rhinitis and others) or several skin allergies. These sicknesses can be treated with help of anti-allergic medicaments (Advair,Haridra,Phenergan,Medrol,Clarinex, Allegra, Koflet, Relent and so on), different antibiotics (Tetracycline HCl,Vantin,Septilin, Ofloxacin, Minocycline and several others) or vasodilators (Xopenex, Ventolin, Symbicort, Serevent, Flovent, Combivent, Atroventand different others). Skin allergycan be also called with help of unfiltered water, chemical substances or some chemical liquids and these manifestations can be presented in view of dermatitis.

Food allergens

Food allergens can be presented in view of practically all food products. But more often the allergy is called by milk, eggs, meat, fish, tomatoes, citrus plants, chocolate, strawberry, crawfishes, honey and so on. Under their hit into the individual’s organism through the stomach the food allergy can appear. Only with help of food allergy testing you can know which of allergens call the allergic reaction. As opposed to this illness the allergic lesions of the gastrointestinal tract developed under the allergen’s hit by other way is called a gastro-intestinal allergy. 

Other types of allergens

Some allergic diseases appear under the hit of pollen into the organism such as the pollen of different plants, insects and so on. It can call the rhinitis, conjunctivitis and other types of seasonal allergies. The most widely-spread allergen is pollen of ambrosia. There are also different industrial allergens including turpentine, mineral oils, nickel, chrome, arsenic, tar oil, tanning agents; various dyes, lacquers, insectofungicides, urea, gums, detergents, and many other substances. The special group of allergens is some physical factors such as cold, warmth, mechanic irritation and several others. It is taken into account that in many cases under the influence of these factors it is formed some specified matters in the organism which then become the allergens. The heightened and changed capability if organism to react on own proteins and cells of some tissues which become allergens is mostly called as autoallergy.
