208 Compliance and Persistence to Grass Immunotherapy Treatment is Comparable for Allergy Immunotherapy Tablets and Subcutaneous Immunotherapy: A Swedish Registry Study

From the Italian ISAAC, AR affects 18.9% schoolchildren and 35.5% adolescents, while severe persistent rhinitis affects 30,700 (3.42%) in Lombardy. Some severe persistent rhinitis was considered indicative for SIT in Group I, and incidence was higher in other groups. SIT is likely to be considered particularly in the subset of patients not completely controlled by symptomatic drugs. In the absence of clinical surveys and given referral study limitations, epidemiological surveys are needed to quantify demand in the pediatric population.
