An allergic contact dermatitis is the skin disease, occurring as the result of hypersensitive (allergic) reaction of human organism to the certain type of the stimulus. To diagnose this disease, the allergists administer classic allergen skin tests. Such disorder, as the allergic contact dermatitis, is quite often connected with the place of work. For example, the allergy to latex among medical workers, to chemical reagents, wool etc. The cause of allergic contact dermatitis lies within home – in household detergents, synthetic clothes, low-quality cosmetics and even children’s toys.
The allergic contact dermatitis usually develops quite slowly: the allergy occurs after a quite lengthy contact of the man with allergen. The disease manifests itself at once; the redness and swelling occur during the contact with allergen, the papulas and vesicles appear. If the contact with allergen is not prevented in time, the allergic dermatitis progresses and can develop into the eczema – the disease, which is harder to treat.
CAUSES OF ALLERGIC DERMATITIS
Indeed, the allergic dermatitis is a delayed-type allergic reaction, in which the lymphocytes mainly take part. In this case, the allergens often are different chemical compounds – chrome, nickel, insecticides, substances, contained in laundry powders etc. The significant number of allergens is contained in drugs and cosmetic products: antibacterial ointments, hair dyes etc. The allergen, in virtue of its small size, usually does not cause allergy by itself, because the immune cells of organism cannot identify it. However, getting into the blood flow, it merges with large proteins of the blood. These compounds play the role of allergens.
The process of excessive immune response usually starts several days before the onset of the first symptoms.
The first signs of allergic dermatitis:
- noticeable skin redness;
- pronounced swelling;
- severe itching in the site of contact with allergen;
- appearance of moist areas and ulcers.
DIAGNOSIS AND TREATMENT
When diagnosing the disease, the allergist first rules out other diseases with similar symptoms: eczema, toxidermia etc. It is easy to make the diagnosis based on the data, obtained while interviewing the patient and examining his skin.
Currently, the patch tests are amply applied for final confirmation of the diagnosis. Thanks to these methods, the doctor may specify the established diagnosis as well as detect concrete allergens, which caused the allergic contact dermatitis.
The treatment of this disease is administered as per results of performed examination. After the allergen is determined, the dermatologist chooses the suitable effective treatment course. The desensitizing therapy is actively applied for combatting the allergic contact dermatitis, the hypoallergenic therapeutic diet is also ordered.
