Asthma is an allergic disease, and allergies are a physical problem that is as difficult to change as obesity, fear of cold, etc. So does this mean that asthma cannot be controlled or prevented? The answer is no. Very often, asthma can be treated or prevented,哮喘測試 not only by avoiding exposure to allergens and minimizing infections and other triggers for asthma attacks, but also by some medications and other treatments. The following experts from Jinan Asthma Hospital will introduce you:

Allergy in the end is an immune disorder, the term is called allergic reaction, most of what we usually call asthma belongs to type I allergic reaction, is due to the human body within a short period of time exposure to more allergens caused by the proliferation of eosinophils in the body and release of a variety of inflammatory mediators, causing a non-bacterial inflammatory reaction, this inflammatory reaction can occur in the whole body, occurs in the skin is our most common rubella block, occurs in the In the gastrointestinal tract, it causes abdominal pain, diarrhea and even blood in the stool, in the blood system it may cause thrombocytopenic purpura, and in the tracheobronchial tract it is asthma. Of course, asthma is a heterogeneous disease, and there are other non-allergic asthma, where the allergen is usually not detected and there is no very obvious allergic inflammatory cell infiltration in the lining of the airways, which may develop into refractory asthma.

The immediate manifestation of asthma is spasm of the airways and small airways at all levels. The patient has difficulty breathing and makes a distinct whistling sound as the gas passes through the fine tubes during wheezing. Why does this happen? Let's consider this.外科醫生 A rash occurs with skin allergies, so if these rashes appear on the lining of the trachea and bronchi, will they instantly block the trachea and bronchi? At the same time, some inflammatory mediators released by eosinophils, such as histamine, can cause violent contraction of the smooth muscles of the airways, which can lead to tracheal spasm, which is the cause of asthma. In addition, allergic reactions can lead to a large amount of fluid leaking from the lining of the trachea and accumulating in the trachea, making the already narrowed trachea more blocked and aggravating asthma symptoms.

At present, the clinical application of more systematic and commonly used allergen detection technology method research mainly through two, one is the skin prick test, one is the blood for allergen antibody screening. Skin prick test is to make a suspension or working solution of allergens commonly found in nature's life, each time the test, a drop on the inside of the arm, and with a fine needle in the site where the liquid has been injected can be gently combined with a needle prick, so that the allergen liquid constantly penetrate deep into the understanding of the skin stratum corneum with the following, so that the allergen contact to the cells under the skin, if a fifteen-minute occurrence of redness and itching at the prick site, it is positive, indicating allergy to the corresponding allergen. Allergen screening refers to the presence of antibodies in the blood that the student's body needs against the allergen, and the corresponding antibody is measured after the blood is drawn, exceeding our certain range mainly indicates allergy to change the allergen, most children's asthma control attacks come and go quickly, this is the same as skin allergies, when encountering allergens rubella block said to come and go, but most of the enterprises quickly disappear, asthma attacks even Sometimes an asthma attack may even occur after several different sneezing processes in China, some without any warning at all, feeling tight in the chest and immediately starting to wheeze. There are some psychological treatment for asthma drug development is also learning efficiency is improved quickly, such as the use of short-acting beta agonists, sucked down immediately to deal with the relief, the pathological mechanism of action of this country asthma is related.

From the above we can also see the pathogenesis of asthma, if you want to cure asthma, either never be exposed to allergens or use drugs to remove allergic factors from the body, these include eosinophils and Miguel antibodies, which are very effective for some people who have moved to cities with good air and warm climate and have been able to get rid of asthma completely. For example, omalizumab, which targets immunoglobulins and lowers immunoglobulin antibody hpv疫苗男levels in the body, has been approved for use abroad as an eosinophil monoclonal antibody and is in pre-market clinical trials in China.

Asthma is an allergic disease that seriously affects the quality of life of patients. Asthma attacks are difficult to cure in most cases, but some methods can be taken to control and prevent asthma attacks and play a good therapeutic role.
