Allergic dermatitis is characterized by seasonal exacerbations
Allergic dermatitis is an inflammation of the skin, which is the result of contact with substances of different types, the so-called allergens. More and more researchers are inclined to the fact that the cause of an allergic reaction is the violation of some protective processes in the human body. According to some reports, this disease affects up to 3% of the population of different regions. But this figure is extremely inaccurate, because not all apply for the treatment of allergic dermatitis to specialists.
Allergy-causing substances are called allergen substances. It can be a liquid, a solid surface or even air (sprays in it chemicals - for example, medicines, perfumes, cosmetics, as well as dust and plant pollen) that can cause the body to react. The difficulty in diagnosing allergic dermatitis lies in the fact that the reaction may occur several days after the very contact with the allergen itself. To date, the most studied atopic, contact and toxic-allergic dermatitis.
Atopic dermatitis and its causes
In case the disease often recurs, is increasing, seasonal exacerbations (remissions) are possible, it is called atopic dermatitis . Atopy is a genetic disease in which the production of immunoglobulin E (IgE) is too high in the human body, which leads to the fact that the human body begins to react to many allergens, which by their nature do not pose a danger to it.
I would also like to say that the immunoglobulin E (IgE) performs a protective function in the human body. Its concentration in the blood of a person not located to allergic reactions is extremely small. In people with allergic diseases, the concentration of IgE is high, both during the period of exacerbation of allergic dermatitis and during remission. Simultaneously, its normal concentration allows the body to respond in time to the pathogen and avoid inflammatory diseases.
According to some studies, T lymphocytes may also cause dermatitis. These cells play an important role in the protective function of human immunity. Linking to the allergen, T-lymphocytes form a complex, resembling an antigen-like property, which takes on the character of an inflammatory process, which is what causes an allergy to us. Part of the T-lymphocytes takes part in the response of the immune system, part goes to the lymph nodes and blood and performs the information-memory function. That's why after like any allergy has begun, the likelihood that it will be repeated at each next contact with this allergen is extremely high, because the cells themselves have made information about the allergen.
Allergic contact and toxic-allergic dermatitis
In case of allergic contact dermatitis, the cause is directly contact with the allergen. In such cases, most often the area of redness, itching or other manifestations concerns is in the area of contact. The intensity of manifestation also depends on the aggressiveness of the allergen, the contact time and the auxiliary catalysts for the development of dermatitis.
In case, when the allergen gets into the body, toxic-allergic dermatitis can develop. Allergic dermatitis is not a contagious disease. It is meant that a person who has redness, itching and other symptoms of allergic dermatitis is not contagious. He can not infect another person. That is, a mother can not infect a baby with allergic dermatitis, but this can be a genetic disease that she passed on to her child. A child can not infect another child or adult of an adult, because the cause of the disease is the increased content of immunoglobulin E and the characteristics of the immune system. Many therapies in the treatment of allergic dermatitis are clearly aimed at inhibiting the function of producing immunoglobulin E. Other manifestations of increased production of immunoglobulin E can be allergic rhinitis or asthma .
Allergic dermatitis in children is often caused not only by contact with allergenic materials and substances, but also by food. Breastfeeding children are prone to overeating, which can provoke its appearance. Very often you can see in children's photos allergic dermatitis, which adults sometimes do not attach importance. Nevertheless, the affected area is very itchy, and this gives a lot of inconvenience even to an adult. Especially if the child is small and does not understand that an allergic rash can not be touched, and it is impossible to explain it to him. In this case, the speed of diagnosis and treatment is extremely important, because a sick child can for a long time not cease to cry and suffer from itching and flaking. A small child can try to scratch an itchy place and this can cause even more harm - by careless movement, he can tear, scratch the skin, and if he scratches, he risks infecting that will start the inflammatory process.
Allergic dermatitis in the baby with age can pass. There is even an opinion that children simply outgrow the dermatitis. This is due to the phenomenon that all the organs and systems of the child's body begin to work more efficiently and allergic reactions no longer arise.
Often in everyday life, allergic dermatitis is called diathesis. This is not an exact definition. Most often diathesis is manifested on the skin in the form of allergic dermatitis. But by itself, diathesis is more a tendency to react the body. That is, it is not really a disease, it is, in fact, the location of the child's body for these or other diseases. And the reasons for its development can be much more than just the effect of allergens. Nevertheless, allergic dermatitis can be one of the manifestations of diathesis. Diathesis in childhood has more genetic or genetic reasons.
Eczema is an inflammatory disease of the skin, with vivid clinical manifestations. The word itself appeared long ago and in translation means effervescence. For by itself this rash is like bubbles, which can be compared to the boiling process, when bubbles appear on the surface of boiling water. Rashes with eczema are also allergic and they are not infectious. Roughly speaking, eczema is one of the manifestations of allergic dermatitis. Happens, eczema appear in cases of violation of the rules of behavior in rashes of allergic dermatitis. For example, with a small rash, when a person continues to scratch, scratch the affected area, aggravating the process with an infectious flora, thereby increasing the lesion, and eczema appears.
Diagnosis of the disease
If you suspect that your child or you have had allergic dermatitis, it is certainly better to contact a specialist. This is necessary in order to avoid other complex diseases. By itself, allergic dermatitis is not a very serious disease, although it often brings a lot of trouble not only to the patient himself, but also to people who care for the sick one way or another. If you can not be sure that this disease is allergic dermatitis, or you have other doubts to avoid the development and progression of another disease, consult a therapist, family doctor, pediatrician or dermatologist.
Symptoms of allergic dermatitis
The main and most common symptom of allergic dermatitis is itching. It is worth remembering that psoriasis, eczema and many other dermatological and dermatovenereological and even gynecological diseases at the heart of the manifestations are itchy. Due to the fact that itching is difficult to control, and the patient continues to scratch the affected areas, the disease spreads quite quickly. There is an allergic dermatitis, the symptoms of which pass quite quickly. But the big difficulty is to refrain from direct carding of the affected area. This is the reason for the increase in the area of the lesion. This also greatly complicates further treatment. After all, the larger the lesion area, the more efforts it is necessary to apply in the treatment of allergic dermatitis.
The location or appearance of the outbreak may also indicate an allergic dermatitis. In young children, as a rule, this face, the zones above the lips, above the elbows, above the knees. Also knee and elbow folds - 70% of people with Alzheimer's disease have manifestations of eczema in these areas.
At the beginning of treatment, the possibility of herpes zoster should be excluded. In this case, you can take a test that will show whether the fungal culture is present. This applies to allergic dermatitis of the hands and feet. In the case when you are 100% sure that you have allergic dermatitis, you can proceed to medical or self-treatment, including outpatient (home) conditions.
Treatment of dermatitis
Treatment regimen, as a rule, consists of several types of therapy. Namely - a diet, symptomatic therapy (a variety of ointments for allergic dermatitis, including pharmacy "talkers"), checking the work of the liver, bile excreting systems and intestines. First of all, you should stop contacting yourself with the allergen itself. In the case where the contact can not be deleted it is necessary to at least limit it. This can be done with gloves, bandages, gauze and other means. Affected areas can be moistened with Burov's solution (antiseptic), applying bandages directly to them. It is also possible to use corticosteroids. Sometimes, in order to remove allergen from the body as quickly and efficiently as possible, diuretics and laxatives are used. With good treatment, the symptoms of allergic dermatitis and its manifestations take place within three weeks, the duration depends on the degree of damage and the effectiveness of therapy. Qualified help in the matter of how to treat allergic dermatitis you can give your family doctor, dermatologist and allergist. Due to the fact that the disease is of an individual nature, often you yourself can know the answer to this question in a narrower segment, but more effective directly for you. Ointment from allergic dermatitis for you can be a regular hypoallergenic moisturizer. It not only helps to avoid irritation and dryness, but also creates a protective layer on the skin, in order to avoid further ingress of the allergen.
Some corticosteroids that are used during the treatment of allergic dermatitis can also be used for prevention, for example betamethasone or fluticasone.
Often in order to effectively cure allergic dermatitis on the face, Cyclosporin ointment is recommended. According to studies conducted in the US, this ointment can cause skin cancer, so be careful when choosing an ointment for allergic dermatitis.
In treating allergic dermatitis that appears on the face, corticosteroids should be used with caution. According to some reports, the use of local corticosteroids can lead to local skin atrophy. In particular, their use around the eyes can cause cataracts and glaucoma, up to loss of vision.
Phototherapy with ultraviolet radiation is widely used not only in our country, but also abroad. Together with additional medicamental treatment, the effect of the procedures can last up to six months.
To date, science is increasingly inclined to the assertion that allergic dermatitis is a congenital or genetic disease. According to some reports, people with dry skin are more likely to have dermatitis. This is due to the fact that the skin is a protective barrier, it protects the body both in the cold and hot season. In cold weather, the skin is especially vulnerable, and dry skin also has many microcracks, which can cause the development of symptoms of dermatitis. On the other hand, excessively oily skin with too open pores can be vulnerable even more, because the infection gets in the pores, dust, dirt. All this is mixed with sweat, which can trigger the allergic reaction. People with dry skin are more prone to allergic dermatitis in the cold period, people with oily skin - in the hot season. If you know that you have problematic dry skin, try to keep it as much as possible in the cold season. Use protective cream, avoid overcooling and frequent touching it. In some cases, frequent contact with hands on the skin of the face can cause irritation. In the case of oily skin, try to carefully observe personal hygiene, wash, clean pores, and less in dusty areas.
Also, try to dress in soft clothes with a maximum breathing effect. Too tough clothes, as well as wool products can provoke dermatitis. Bed linen and sportswear should absorb sweat well, they need to be washed as often as possible. If you notice any manifestations of an allergic reaction, try to be as cautious and competent as possible about the choice of clothing and fabrics that come into contact with your body. Pay attention to the material from which our towels, napkins, mittens and gloves are made and much more. If you already know that you have allergies to some materials, try to avoid such materials in everyday life.
Many metals or their contents in various alloys of ornaments, can cause all sorts of allergic reactions. It is necessary with extreme caution to treat jewelry, especially if you already have any manifestation of an allergic reaction. You may notice that many manufacturers write on their products whether allergy testing has been passed, try to pay attention to such notes. Nevertheless, allergic reactions are very individual, and sometimes the body reacts to the safest materials. If you notice the appearance of itching, change clothes, change jewelry and rinse the surface of the lesion well. Some studies have confirmed that rubber-containing components can cause allergic dermatitis on the hands. Therefore, caution should also be taken to select rubber-containing gloves. It is desirable that they undergo dermatological testing.
Take care of the choice of cosmetics and perfumes, as well as any household chemicals. If possible, avoid direct contact with them or limit contact time. For example, if you are allergic to any detergent, try another brand. If the allergy manifests itself on all kinds of powder, try using it in gloves and rinse your clothes several times so that the microparticles of the remedy do not stay in the tissues. In those cases where you know about your tendency to allergic dermatitis, test the substances before using a new allergen-containing drug. Try to test new cosmetics on the inside of the hand - the skin of this place will quickly react to the allergen, and you will be aware of the presence of the reaction and be able to exclude further contact.
Avoid any contact with allergens, that is, with those substances that, according to your observations, cause dryness, itching, burning and redness. Sometimes it is enough just to exclude contact with a certain allergen and the disease itself passes very quickly. In such cases, there is no need for any additional treatment, diagnosis and advice from a doctor. In time revealed the first symptoms of allergic dermatitis and timely therapy will help to avoid many unpleasant sensations. Symptoms of allergic contact dermatitis occur either immediately, or for several days. For example, in the case when you are allergic to the neomycin component, the reaction may begin in 7 days.
Diet for allergic dermatitis, as a rule, is not only a restriction in the use of certain foods, but also in a more responsible selection of medications (furacilin, antibiotics, sulfonamide). If you know what allergies are, just exclude this product or drug. Diet in allergic dermatitis has the basic principles. Excludes spicy, salty, sweet, pepper, smoked products, canned food, excess seasonings, honey, coffee, citrus, exotic products, eggs. The basis of the diet should be meat (only boiled), cereal, vegetables, compotes, dried fruits.
