Atopic dermatitis is increasingly common among children, and the incidence in cities is much higher than in rural areas.
Atopic dermatitis, as a rule, has an early onset and a recurrent course (proceeds with constant exacerbations). According to statistics, in 40-60% of children, the manifestations of atopic dermatitis fade with age and may disappear completely, but, unfortunately, in others, the clinical manifestations and relapses of the disease can be observed during long time.
In modern medicine, under atopic dermatitis include: chronic inflammatory skin disease of allergic nature, in individuals with a genetic predisposition, characterized by a recurrent course, itching, dryness, presence of vesicopapular eruption and lichenification (according to age).
Causes of atopic dermatitis.
Many factors were identified that lead to the development of atopic dermatitis in children, but one of the main ones is genetic predisposition.
The second most important factor is – allergens.
The following types of allergens are distinguished:
- Non-infectious: food pollen, medications, inhalation, chemicals, house dust, etc.
- Infectious – bacteria, viruses, ticks, fungi.
The most common cause of the development of atopic dermatitis in babies are food allergens.
Animal origin – Cow’s milk, chicken egg, goat milk, fish and seafood.
Vegetable origin – Legumes (nuts, soybeans, peas, lentils, beans), cereals (wheat, rye, barley, corn), red and orange fruits and vegetables (strawberries, strawberries, peaches, citrus fruits, persimmons, beets, carrots, etc.) , Bee products (honey, propolis).
Also, keep in mind the presence of cross allergy between different foods.
Thus, the cross reactions can be between the following products:
- Cow’s milk has a cross with cheese, kefir, goat’s milk, sausages, sausages, cakes, white bread, veal and veal.
- Eggs – with products that use egg white and yolk, chicken, mayonnaise, feather pillows
- Fish – river and sea fish, marinade, crabs, shrimps, lobsters, crayfish, seafood, caviar.
In older children, other allergens (pollen, ticks, fungi and house dust begin to predominate in the exacerbation and development of atopic dermatitis).
Predisposing factors for the development of atopic dermatitis.
Allergic history loaded
Non-compliance with the diet of the mother during pregnancy and lactation.
Antibacterial therapy performed during pregnancy or in early childhood.
Previous artificial feeding
Dysfunction of the gastrointestinal tract from birth, dysbiosis, cholecystitis, cholecystosis.
Hyperreactivity of the skin.
Age-appropriate skin care
Lack of trace elements and vitamins in the diet.
Worms and parasitic invasions.
Poor living conditions (especially high temperatures combined with low humidity)
Violation of vaccination regulations.
Frequent infectious diseases
Negative weather influences – very high or low temperatures
Smoking: passive smoking is especially important for young children.
Excess in xenobiotic and nutrient foods, fertilizers.
The lasting psycho-emotional stress.
Of course, individually, these factors can not cause the development of atopic dermatitis (except by inheritance), but the more predisposing factors affect the child, the greater the risk of developing the disease. It should also be taken into account that these factors not only contribute to the development of atopic dermatitis, but can cause its aggravation or exacerbate the severity of the course, in cases in which the child already has this condition.
