Different constitutional allergens are also different

Last year, a topic entitled "How outrageous to allergen can be" appeared on Weibo hot search. Netizens have left their wonderful allergies in the comment area:

"Since birth, I don't know what allergies are. I didn't know what I was allergic when I ate half a pound of rapeseed flowers in the remote villages in Yangzhou. My lips became like sausages."

"My target is allergic to Chuangcai Paste, glue, and tape. I dare not stick to Chuangya. After the post is pasted, the skin is red like a brand, and it is very itchy."

"When I was a kid, I steamed eggs and egg custard. When I ate it, I became red. I always thought that I was allergic to eggs. I dared not eat it for more than 20 years. I went to the hospital for examination. The doctor said that my allergens were onion. Get up, every time the family steamed egg custard, it is really wronged with eggs. "

"Suddenly fainted during the military training, my classmates thought that I had a heat stroke and sent me to the hospital. After the examination, the doctor told me that it was sunny."

Wang Siqin, director of the Director of the Perverted Reaction Department of Henan Provincial People's Hospital, said that according to the way to enter the human body, allergens can be divided into inhalation allergens, food -induced allergens, and contact allergens.

Inhalation allergens generally refer to antigenic substances that cause allergies through breathing, such as pollen, catkins, dust, cold air, animal dandruff, etc.

Eating allergen generally refers to antigenic substances that cause allergies through diet, such as seafood, alcohol, milk, and some drugs.

Contact allergens generally refer to antigenic substances that cause allergies through touch, such as nickel metals, cobalt metals, cosmetics, etc.

In addition to the above common, there are also many rare allergens such as sunlight and glue mentioned by netizens.

Zhang Qiuxing, chief physician of the allergic reaction department of Henan Provincial People's Hospital, said that allergic diseases are also related to excessive pressure, smoking and environmental pollution.

During the process of the body's opposite pressure, various hormones can be produced, which will have a certain effect on the production of allergic diseases.

Exposure to outdoor pollutants and mothers can increase the probability of children suffering from allergic diseases in pre -delivery and postpartum smoking.

The incidence is continuously increased.

According to the Statistics of the World Allergies (WAO), 30%to 40%of people around the world are suffering from allergies.

The incidence of allergic diseases in China has continued to rise. From 4 months to elderly people over 60 years of age, allergies have occurred in various groups. It is estimated that the patients with more than 200 million people.

Wang Siqin introduced that allergies are actually an excessive sensitivity and excessive response to some normal substances in the outside world.

From a medical perspective, allergies are an abnormal, pathological immune response, and it is the human tissue dysfunction or abnormal immune response caused by repeated stimulation of different antigenic antigen or the same antigen.

These normal substances have no response to ordinary people.

However, for people of allergies, this normal substance can cause abnormal immune response in their bodies, leading to harm of body tissue, and people call these substances as allergens.

"Allergic diseases are systemic and systemic diseases, and have certain geneticism." Wang Siqin said.

If the parents have an allergic disease, the probability of passing the children is 40%to 50%.

If both parents have allergic diseases, the probability of children's allergies will be as high as 70%to 80%.

If both parents do not have an allergic disease, the probability of children with allergic diseases is 20%to 40%.

Patching test and blood drawing test can detect allergens

The allergens of patients with different allergic diseases are different, how to detect it? How to treat it?

Wang Siqin said that allergic diseases are also known as perverted response diseases, clinically divided perverted reactions into type Ⅰ (speed hairstyle), type II (cytotoxic), type III (immune complex type), type IV (late hairstyle) Essence

At present, the testing of allergens and recognized methods at home and abroad are mainly two categories: in vitro tests and in vitro tests.

The in vitro test includes a thorns test and spotting test. The in vitro test is to take the patient's blood test.

"Generally speaking, clinically use spotting tests and blood drawing tests.

Patch tests are mainly used to detect contact -allergens, such as metals and cosmetics. Blood drawing test is a specific antibody in the patient's body.

At present, these testing methods are perverted for type I (speed hairstyle) and type IV (late hairstyle), type II (cytotoxic type) and III (immune complex type) for temporarily no reliable detection methods. "Wang Siqin introduced.

There are currently four methods for the treatment of allergic diseases: far from allergens, drug treatment, targeted therapy and desensitization.

"Among them, desensitization therapy is a specific immunotherapy and is a treatment method for causing allergic diseases, such as allergic asthma, drugs, and specific dermatitis.

In layman's terms, it is to allow patients to contact the allergens in small amounts first, and then gradually increase. After reaching a certain degree, the body will produce immune tolerance.Until contact with these substances, allergies are reduced or even disappeared.Wang Siqin told reporters.

Pay attention to the high incidence of allergic diseases in summer

With the arrival of summer, there are more and more substances that cause allergies in the environment, such as strong ultraviolet rays and mites, so summer is also a high incidence season for allergic diseases.

Wang Siqin suggested that allergens are detected in advance in the season when allergies are high, so as to clarify what material is allergic to and prevent it in advance.

When you go out, wear disposable masks, scarves, etc., you can also bring sunshade products such as sun umbrellas and sun hats.Cats or dogs are allergic to people, do not contact cats and dogs at close range.

Patients who are allergic to pollen should be reduced to places in the suburbs, grasslands, pastures and other places.Pay attention to rest, ensure sufficient sleep while maintaining smooth emotions.

Once allergic symptoms occur, seek medical treatment in time and standardize treatment.
