Allergen Immunotherapy AIT

Allergen immunotherapy (AIT) is the only effective treatment for allergic diseases that induces immune tolerance while reducing symptoms in patients with asthma and allergic rhinitis (AR). The principle of this therapy is to reduce the symptoms of allergic diseases by inducing tolerance to allergens. By repeated long-term exposure to a designated dose of allergen, immune responses can be changed, protective immunity can be induced, and patients can tolerate future allergen exposure. Common applications of AIT for respiratory allergies include subcutaneous immunotherapy (SCIT) and sublingual immunotherapy (SLIT). SCIT involves repeated subcutaneous injections of increasing doses of allergen, starting with a low initial dose, and gradually increasing to a higher dose. SLIT is a non-invasive and well-tolerated therapy that is effective in treating respiratory allergies.
