What is allergen immunotherapy?

Allergen immunotherapy (AIT) has more than 100 years of history in medicine. The first study with this treatment for allergic diseases was published in 1911 in the Lancet by Leonard Noon and John Freeman. AIT is considered to be the only treatment capable of modifying the specific immune response against allergens such as house dust mites, molds, animal dander and pollens. This treatment is effective in controlling allergic rhinitis, rhinoconjunctivitis and asthma, and recent studies have also shown good results in the treatment of atopic dermatitis.
