Tratamiento de la rinitis alérgica en pediatría en Argentina. Documento de actualización

Allergic rhinitis (AR) is the most frequent allergic disease. Prevalence in children and teenagers in Argentina ranges between 22.3% and 34.9%.  Given this situation, members of the scientific committees of Pediatrics and Rhinitis of the Argentinian Association of Allergy and Clinical Immunology (AAAeIC) have reviewed scientific evidence in order to update the therapeutic regulations of this pathology in the pediatric population. The classification and categorization of AR are currently in full review all around the world. It is necessary to make a differential diagnosis with other non-allergic types of rhinitis in children, and to confirm AR based on the clinical history, physical examination, determination of bio-markers, and/or skin tests. Non-pharmacological treatment includes education and guidelines of environmental control for allergens such as dust mites, anemophilous fungi, animal epithelium, and pollens. Step pharmacological therapy is proposed according to the control of the disease. Second-generation, non-sedating anti-histamines are the first line of therapy. The association with oral decongestants is not recommended in children under 4 years of age. Inhaled corticosteroids are the first choice for both moderate and severe forms. This document warns pediatricians about the importance of an early diagnosis, the rational use of step pharmacological therapy, and specific immunotherapy in children.
