Cause of atopy
Genetic propensity
In a new building, a lot of harmful substances such as volatile organic compounds (VOCs) and formaldehyde (HCHO) emitted from the finishing materials and building materials are discharged so that the residents of the building are exposed to the light symptoms , Fatigue, dyspnea, rhinitis, dermatitis, and chronic bronchitis. These sick building syndromes threaten the health of the occupants and result in lower productivity and efficiency.
Mechanical tendency
Two immunological abnormalities in atopic dermatitis patients are ‘lgE overproduction’ and ‘cell mediated immune dysfunction’, which is the same with other allergic symptoms. Overgrown immunoglobulin E (IgE) in the brain of patients with atopic dermatitis is attached to the surface of the inner or outer blood vessels or mast cells of the skin, and when the allergen penetrates the body again, the allergen and lgE bind It stimulates mast cells and secretes chemicals such as histamine stored in the cells. These chemicals stimulate the blood vessels and skin, causing red edema and itching in the skin, and causing or exacerbating atopic dermatitis.
Environmental Psychological Impact
Urbanization
Regional differences in the occurrence of atopic dermatitis are closely linked to urbanization. Compared to Eastern Europe, it is more frequent in developed countries than in Western Europe and developing countries. Immigrant studies have shown that immigrant children from the East to Australia are less frequent than those born in Australia.
Instantiation Life Style and Dietary Habits
In the past, a researcher from East Germany has claimed that the increased use of margarine is closely related to the increased incidence of allergic diseases. Recently, increased absorption of unsaturated fatty acids, especially the absorption of linoleic acid, has been reported to be a risk factor for allergic rhinitis and asthma I did. Many mothers reduce breastfeeding and provide their babies with diverse foods, increasing the chances of infants being exposed to allergens.
High economic status
It is said that the incidence of atopic dermatitis is higher in the high-income group than in the low-socioeconomic group, but this is a controversial condition.
Pollution
When there is no record of the problem of atopic dermatitis when using wood and coal, and when it is estimated that the incidence of atopic dermatitis is low in developing countries and fujingu districts compared to developed countries, pollution and environmental pollution are suspected to be the cause of atopic dermatitis There are many times.
Indoor air Factors of harmful environment
Petrochemical organic compounds (VOCs) from paint, wallpaper, adhesives or interior fittings and furniture are contributing to environmental diseases of atopic asthma.
