Can desensitization therapy improve symptoms of allergic asthma?

Generally, desensitization therapy can improve symptoms of allergic asthma, but it must be carried out under a doctor's guidance, with strict adherence to the treatment plan and precautions. Analysis is as follows:

Desensitization therapy, also known as specific immunotherapy, works by gradually increasing the patient's exposure to allergens, prompting adaptive changes in the immune system, thus alleviating or eliminating allergic reactions. For patients with allergic asthma whose allergens—such as pollen or house dust mites—are clearly identifiable, and whose asthma symptoms are mainly triggered by one or a few specific allergens, desensitization therapy may be a viable treatment option.

This therapy is suitable for patients with allergic asthma caused by clearly identified inhaled allergens, who show positive results in allergen testing and have elevated serum specific IgE levels. For these patients, desensitization therapy can alleviate or eliminate allergic symptoms, reduce the frequency and severity of asthma attacks, thereby improving quality of life.

However, desensitization therapy requires high patient compliance due to its long treatment duration. If patients cannot adhere to the full course of treatment, it will be difficult to achieve the desired therapeutic effect.
