An important step in the treatment of asthma in children: allergen testing

Every year on the first Tuesday of May

Designated as World Asthma Day

The past 3 May 2022 marks the 24th World Asthma Day

The theme is "Closing gaps and achieving homogeneous management of asthma"

The following article for everyone to popularize the "important steps in the treatment of children's asthma: allergen detection", I hope that the allergy and asthma awareness of allergy Star Treasure parents will be improved, and more and more attention will be paid to allergen detection.

Children's asthma is mostly allergic asthma, of which inhaled allergens are of great significance in the occurrence and development of asthma, and the "Recommendations for standardized diagnosis and treatment of children's bronchial asthma (2020 edition)" proposes to conduct allergen testing as much as possible for all children suspected of asthma, especially young children who are difficult to complete routine lung ventilation testing, and early inhalation allergen detection can help diagnose, intervene and predict the long-term outcome of asthma [1].

With the development of society, economy and culture, more and more ordinary people have begun to understand the importance of allergen testing. Doctors often receive consultations from parents who take the initiative to do allergen testing. In life, there is such a group of children, allergic to milk, eggs, dust mites, pollen, animal fur, etc., and a detail that can be inadvertently may cause the child's life to be in danger. In recent years, the incidence of bronchial asthma in children on the mainland has increased. About 70% to 80% of children with bronchial asthma develop at age 5 years, and about 20% have a family history. Most children have a history of allergic rhinitis, childhood eczema, and food (drug) allergies, and if bronchial asthma is not diagnosed and treated early, irreversible stenosis and airway changes occur in the airways as the condition progresses[2].

Professor Hong Jianguo, a pediatric asthma expert at Shanghai First People's Hospital, interpreted the "Recommendations for the Standardized Diagnosis and Treatment of Children's Bronchial Asthma (2020 Edition)" and pointed out: "Asthma is an allergic disease, and the onset of asthma is due to its own constitution plus external factors stimulated." Professor Xiao Yixiao, director of the Department of Pediatrics at Xinhua Hospital affiliated to Shanghai Jiao Tong University School of Medicine, said: "Asthma is a chronic inflammatory disease of the airway, and for most children, this inflammation is mainly caused by allergies. ”

2 What are the common allergens in daily life?

Inhalation allergens mainly include dust mites, pollen, animal secretions, mold, indoor dust, smoke and so on.

Common food allergens include milk, eggs, seafood, peanuts, mangoes, pineapples, etc.

3What is the practical significance of definitive allergens?

1. Determine whether your child's asthma is related to allergies, food allergens or inhalation allergens?

2. If the allergen is detected, that is, the risk factors that cause asthma exacerbation or poor control are screened out, so that contact with the allergen can be avoided or reduced. If it is a milk and egg food allergy, reasonable taboo is very important; if it is a pollen allergy, you should pay attention to wearing a mask outside and washing your nose at home; if it is a mite allergy, pay attention to cleaning, you can also desensitize treatment, pay attention to these details, you can greatly reduce the cause of asthma in children.

3. After the allergen is checked out, it is also meaningful in treatment. At present, mite desensitization reagent is the main desensitization drug at home and abroad, and early desensitization treatment can prevent children from developing from allergic rhinitis to asthma [3].

According to the World Allergy Organization (WAO), the total prevalence of allergic diseases worldwide is as high as 22%, of which the prevalence of allergic rhinitis is 17%, and the prevalence of allergic asthma is 11%. Professor Wang Xueyan, director of the Department of Allergy at Beijing Shijitan Hospital, said in the "Media Experience Camp Activity" that in China, there are more than 100 million patients with allergic rhinitis and nearly 20 million patients with allergic asthma. Therefore, the identification of allergens is crucial for the treatment of allergic asthma, allergen testing should not be ignored, find the allergen, asthma treatment plan can be curative and curative [5].

4 What are the methods of detecting common allergens in daily life?

At present, there are several methods for the examination of allergens: skin prick test, serum-specific IgE measurement, etc.

Skin prick test: convenient and simple, the entire detection process only takes about 30 minutes, but the asthma attack period is not recommended, there is a risk of aggravation of symptoms or even shock; another need to stop the drug for 3 days and then test, affecting the relief of treatment; the operation process and continuous tingling sensation are uncomfortable for infants and children.

Serum-specific IgE determination: easy to operate, more applications, relatively large number of detectable allergens, and accurate results.

5What kind of people are suitable for home detection allergens?

1. Have small symptoms, suspect that they are allergic, but are too lazy to go to the hospital to confirm;

2. During the epidemic period, it is necessary to work from home, and it is recommended to go out less;

3, do not want to go to the hospital, want to try to avoid cross infection (especially children allergies);

4. Pursue quality of life and efficiency, and pay attention to service experience.

So is there a time-saving, labor-saving, simple and convenient home allergen detection method?

On the 24th World Asthma Day, we will recognize asthma, focus on asthma, and control asthma, just as the "Recommendations for standardized diagnosis and treatment of bronchial asthma in children (2020 edition)" recommends that allergen testing be carried out as much as possible in all children suspected of asthma, especially young children who have difficulty completing routine lung ventilation testing, and early inhalation allergen detection can help diagnose, intervene and predict the long-term outcome of asthma [1].
