Allergy Epidemic of the Century

World Allergy Day is celebrated on July 8 every year. It aims to prevent allergic reactions and allergic asthma by raising awareness of allergic diseases among all people. According to the results of an epidemiological survey of allergic diseases in 30 countries published by the World Organization of Allergy on the first World Day of Allergic Diseases in 2005, 22% of the total population of these countries suffered from various allergic diseases, such as allergic rhinitis, asthma, conjunctivitis, eczema, food allergies, drug allergies, and severe allergic reactions, etc. The more developed the country, the higher the prevalence of allergies. The more developed the country, the higher the incidence of allergy, some countries even reached 40-60%. As for China, with the rapid advancement of GDP level, allergic diseases have likewise affected the nation, especially newborn children, by leaps and bounds. It has been an epidemic of the century, and after nearly a decade of development, the incidence of allergy in children in China should be around 30%, which means that every three children may have one allergy, but it has not been standardized and controlled. What are the symptoms of allergies in children, and what are the conditions that require attention for possible allergies? In general, allergies in children affect mainly the skin, digestive and respiratory tracts. And the incidence is getting higher and higher. Anyone with the following conditions should pay attention to the possibility of allergy. 1, repeated eczema, hives, itchy skin; 2, repeated blood in stool, diarrhea; 3, frequent nasal congestion, sniffles, sneezes, snorting, scratching the nose, rubbing the eyes; 4, frequent colds, repeated coughing, phlegm, wheezing; 5. One of the parents has an allergic disease. What is the course of a child’s allergy and why is early diagnosis and treatment important? The earliest symptoms of allergy are eczema on the skin and blood in the digestive tract. Afterwards, if the allergy is not under control, allergic rhinitis, bronchitis and asthma will gradually appear. There are even children who do not have skin allergies or gastrointestinal allergies, but have recurrent symptoms of allergic rhinitis from the first 1-2 months of life, and 25% to 38% of patients with allergic rhinitis will develop asthma. Therefore, it is extremely important to detect allergic symptoms in children in a timely manner and to diagnose and treat them early. Many childhood allergies can be cured and reversed if they are treated in a timely and standardized manner. However, if they are not diagnosed and treated in time, many children lose this opportunity and have irreversible chronic damage to their airways, becoming adults with chronic allergic airway disease. Children’s allergies are so common and early diagnosis and treatment is so important, so what is the treatment situation in China now? The rapid development of childhood allergies in China is so alarming that the training of qualified doctors is far from keeping pace, and is destined to be a heavy health burden, both for families and for the country. According to a report by former Johnson & Johnson senior researcher Bai Zhonghu, the number of doctors who can fully understand and standardize the diagnosis and treatment of children’s allergies is less than 18% even in the tertiary hospitals, and less than 6% in the hospitals below the tertiary level. Nationwide, less than 5% of hospitals are able to standardize blood tests for children’s allergens. Add to this a misdiagnosis rate of around 30% of first visits worldwide, and combine this with the fact that Chinese children do not have a family doctor, resulting in multiple first visits. Too few allergic children receive standardized diagnosis and treatment, and the vast majority of them are submerged under the iceberg, letting the allergy process gradually develop. Moreover, due to the Chinese characteristic of setting up departments based on specialized diseases, a child with skin, digestive, respiratory, etc. allergies needs to go to pediatrics, dermatology, ENT, and allergology departments repeatedly like a product on an assembly line, which leads to repeated first-time visits, resulting in higher chances of misdiagnosis, and leading to a poor experience and efficacy of the treatment. How are allergies diagnosed in children? How are children’s allergies diagnosed? The diagnosis of allergies in children is a difficult one, especially in infants and young children, as the symptoms are atypical and can only be assessed by a combination of family history, symptoms, and eosinophils. If both parents are allergic, the likelihood of the child being allergic is more than 70%, if one parent is allergic, it reaches 50%, and even if neither parent is allergic, the likelihood of the child being allergic is still 15%. Moreover, due to the rapid westernization of the country’s lifestyles, refinement, and changes in the environment, the incidence of allergies in children is much higher than we can control. The most practical allergen test is to draw blood for specific IgE, food allergy and intolerance may need to test IgG, skin prick is mainly for specific IgE test, blood test is not affected by the application of medication, and skin prick needs to stop taking medication for at least one week. Of course, the specific allergies have to be observed through life, blood sampling or skin prick is only a direction, and parents need to find out more and more in their life in order to clarify what the allergens are. Bioresonance allergen testing is not recommended and is not accurate. How are children’s allergies treated? The most important thing in the treatment of children’s allergy is the avoidance of allergens. At an early age, it is not possible to identify the allergens through allergen testing, so it can only be avoided according to the doctor’s experience and normal life observation. However, no matter how to avoid, allergic children will inevitably be suddenly out of the situation, so drug treatment is necessary, the current application of anti-allergy drugs in children has been very mature, efficacy and safety are very good, in general, most of the children’s allergies, through oral anti-allergy drugs combined with topical corticosteroid can be very well controlled. Many children have substantial immune maturation between the ages of 3-5, 6-8, and 11-13 years, with the potential to reverse the allergic process. Therefore, the most important thing for infants and young children is to standardize the application of medications to prevent recurrent episodes of airway inflammation causing irreversible damage to the child’s airway. In reality, many allergic children do not adhere to standardized treatment because they do not recognize the significance of such treatment, and they always resist the prolonged application of anti-allergy medications and corticosteroids, believing that it is not too late to treat them when they have an attack. In this way, the opportunity to cure allergies in childhood is lost. So, with the right treatment, an allergic child can sometimes be a blessing in disguise. The confidence and knowledge of the parents is the basis for the treatment of the allergic child.
