Childhood asthma, the need for desensitization and what needs to be desensitized, is a very nagging question in the minds of many parents.
First of all, do I need desensitization for this child? If I do desensitization, I spend money, suffer, and my child’s symptoms improve, I spend more money willingly; if it is not effective, I am sure I regret it. Zhou Haoquan, Department of Pediatrics, Anhui Provincial Hospital
With this problem in mind, let’s take a look at which children need desensitization.
Desensitization, as the name implies, takes off the allergy. That is, I have a child with allergies, an allergic asthma, but not all asthma is allergic asthma. What is allergic asthma? In life, we can observe that a child may be “hypersensitive” to some things, such as fish, shrimp, milk, etc., but more often to inhalants, such as mites, pollen, etc. In the hospital, we can find out that the child is allergic to something through tests such as the allergen test, of which the skin prick test is the gold standard. It confirms that the child is allergic to asthma, which is a prerequisite for doing desensitization.
Next, what is the choice of desensitization: subcutaneous injection, sublingual or transnasal drip? There are advantages and disadvantages to each of these methods. Sublingual and intranasal drips are safe and inexpensive, but the current standardization of reagents is not enough and the efficacy is not good; subcutaneous injection is easy to cause allergy and expensive, but the efficacy is relatively good.
Our pediatric clinic now carries out desensitization of house dust mites in children with allergic asthma and has accumulated a lot of experience. First of all, children with asthma or rhinitis who are allergic to house dust mites and are older than 5 years old can undergo desensitization treatment for a period of 2.5 to 3 years.
