Allergen of allergic eczema
1. Food: Fish, shrimp, crab, eggs and milk are the most common. Followed by meat and some plant foods.
2, drugs, can cause the disease. Penicillin, sulfonamides, furazolidone, serum vaccine, etc. Eczema is often caused by immune mechanism. Aspirin, morphine, atropine and vitamin B 1 are histamine releasing substances, which can directly cause mast cells to release histamine and cause eczema.
3. Infection: including viruses (such as influenza virus and hepatitis virus), bacteria (such as golden grapes), fungi and parasites (such as roundworms).
4, animal and plant factors, such as insect bites or inhalation of pollen, feathers, dander, etc.
5, physical factors, such as cold and heat, sunlight, friction, pressure, etc. can cause. The skin of eczema patients is not only red, swollen and covered with blisters, but also itchy. Severe itching will make patients scratch the affected skin, thus aggravating skin inflammation. Once the skin is scratched, it will not only bleed a lot, but also cause infection. Eczema tends to gather in the family, but it is not contagious. Patients often start to get sick in infancy, and it is difficult to get rid of this disease throughout adolescence. It should not be overlooked that adults may also suffer from eczema. For infant patients, eczema usually occurs on the head or face. For children and adults, skin lesions caused by eczema mostly occur in elbows, knees, face, neck and upper chest.
In addition, when people live under the influence of such adverse environmental factors for a long time, it will lead to immune dysfunction and eventually lead to allergic reactions to the environment, thus causing eczema.
Prevention and treatment of eczema
For those who are prone to eczema, contact with substances that irritate the skin is not the only reason. Inhaling or eating allergens can also cause eczema. The advice for patients with eczema is the same as that for patients with other allergic diseases, that is, try to avoid contact with any value that may induce eczema. However, it is easier said than done, especially for people with high allergies. Because any common substances in daily life, such as dust, soap, and even sweat discharged by oneself, may be allergens, it is difficult to completely avoid all this. In addition, stress will make eczema worse, so don't put too much pressure on yourself, and learn to relax moderately.
At present, the treatment of eczema is mainly to relieve itching and inflammation in the affected area. Topical ointment containing hydrocortisone and other anti-inflammatory ingredients can relieve the discomfort of the affected area, and applying moisturizing lotion to the affected area can also relieve the skin. Taking antihistamines can also relieve allergic symptoms. But they can't fundamentally adjust their allergies.
Many studies have confirmed that probiotics can effectively prevent and treat allergic dermatitis. Scientists in Finland studied 159 pregnant women. They all have a family history of allergic eczema, urticaria or asthma, so their children are at higher risk of eczema and urticaria in the future.
Before delivery, these expectant mothers take probiotic supplements for 2-4 weeks. After the baby is born, the breastfeeding mother continues to take the same medicine as before delivery for 6 months. Babies who receive artificial feeding need to be supplemented with probiotics every day. Two years after the experiment, these children are unlikely to have allergies.
There are 2000-3000 kinds of common antigen substances that cause allergic reactions, and nearly 20 thousand kinds are recorded in medical literature. At present, 22%-25% people in the world suffer from allergic diseases (urticaria, eczema, allergic cough), among which children account for the largest number. In addition, if parents suffer from allergic diseases without effective treatment, the chances of their children suffering from allergic diseases are high. With the development of science and technology, all kinds of probiotics are popular all over the world. At the same time, the study of probiotics has become a worldwide research hotspot.
After entering the 2 1 century, various countries and regions have increased their investment in probiotic research, and technology research and development has also advanced by leaps and bounds. Repeated experiments by scientists finally confirmed that human allergy is only the superficial phenomenon of disease response, and the fundamental reason why allergic diseases are difficult to cure is the poor activity of digestive enzymes and beneficial bacteria in the gastrointestinal tract. Only by increasing the corresponding probiotics in the intestine and activating the activities of digestive enzymes and beneficial bacteria in the digestive tract is the ideal way to eradicate allergic diseases.
In the research on the treatment of allergic diseases in the world, an important achievement in the field of allergic diseases was put forward in 2000: probiotic adjuvant therapy. Even the World Health Organization (WHO) pointed out in the guidelines for the treatment of allergic diseases that probiotic adjuvant therapy is the safest and most effective health therapy that can radically cure allergic constitution at present.
Lactobacillus salivarius, a patented probiotic strain of Xinmin Kang, activates a series of cellular reactions and produces a series of physiological reactions by contacting with a special cell in the intestine, which can finally reduce the antibody-immunoglobulin IgE in human blood, fundamentally regulate allergic constitution, enhance immunity and completely treat allergic diseases. After taking Xinmin Kang and fixing it on intestinal mucosa, it can promote the secretion of interferon (IFN-Y), regulate TH 1 immune response, inhibit immunoglobulin IgE, and improve the allergic phenomenon of TH2 immune response. Reduce the production of specific IgE antibody in serum; Adjust allergic constitution, inhibit allergic reaction and prevent allergic recurrence; Adjust the immune system, balance and enhance the body's immunity; And can reduce the influence of carcinogens on cells.
Eczema in children will make the baby itchy, sleepless at night and restless. Drug treatment has a certain effect. If necessary, you can use anti-inflammatory, antipruritic and anti-allergic drugs under the guidance of the hospital, and don't use any hormone ointment such as "skin relaxation" yourself. Because excessive external use of these drugs will be absorbed by the skin and bring side effects, long-term use will also cause local skin pigmentation or mild atrophy. Children often relapse after stopping taking drugs.
