Immunotherapy Can Protect Against Asthma in Children with Allergic Rhinitis

Most patients with asthma have rhinitis suggesting the concept of ‘one airway one disease’ or ‘united airways’. However, not all patients with rhinitis present with asthma.

According to a study published in Allergy, immunotherapy for allergic rhinitis in children prevents the development of asthma for up to 7 years after treatment ends. Immunotherapy was administered for 3 years with high-dose standardized allergen extracts and the total study period was 10 years.

According to the authors, "immunotherapy should be recognized not only as first line therapeutic treatment for allergic rhinoconjunctivitis but also as secondary preventive treatment for respiratory allergic disease."

On a side note, the whole September issue of Allergy is devoted to allergic rhinitis.
