ABSTRACT

The prevalence of allergic asthma is still increasing, which affects the quality of life of patients, threatens their lives, and brings enormous social and economic burden. Allergen immunotherapy (AIT) is the only treatment that can alter the progression of the "Atopic March". It has been widely used in the treatment of allergic rhinitis and conjunctivitis, and its role and effect in the treatment of allergic asthma have been gradually recognized. A few studies have shown that AIT may have a preventive effect on the development and progression of allergic asthma. In this article, the definition of tertiary prevention of allergic asthma is described, and the respective role of AIT in primary, secondary and tertiary prevention of allergic asthma is summarized and analyzed. The aim of this article is to provide evidence for the prevention and control of allergic asthma.
