SUBLINGUAL IMMUNOTHERAPY IN CHILDREN: STATE OF ART.

Allergic immunotherapy (AIT) today represents a therapeutic practice for the treatment of allergic diseases such as rhinitis or asthma and is recognized as the only treatment able to modify the natural history of the disease. Administering gradually increasing doses of the causative allergen, AIT, has the objective of achieving immune tolerance against allergens. One of the administration routes most used in clinical practice is represented by the sublingual route. Current research on sublingual immunotherapy (SLIT) is focused on confirming the efficacy for all the different relevant allergens, on a better definition of allergen extracts and the improvement of their immunological properties and safety, on the identification of best treatment regimens, and on the possibility of extending the clinical indications. The aim of this review is to describe the most recent step in the field of SLIT development.
