Decision-making for pediatric allergy immunotherapy for aeroallergens: a narrative review.

There has been exciting progress in diagnosis and in the treatment of allergic patients. The objective of this review is to summarize the most relevant contributions in the past 10 years with a special focus on the pediatric population allergic to aeroallergens and provide the most relevant references and practical issues for the decision-making. Current guidelines on allergy diagnosis recommend a thorough clinical history as the first step, followed by allergen extract testing using an in vivo prick test and/or an in vitro specific IgE test. Molecular diagnosis is recommended when previous tests are inconclusive. In practice, the most important factors to decide the AIT treatment are the actual intensity and duration of the patient's symptoms and the availability of appropriate AIT products for the patient's sensitization profile at high allergen concentrations and with confirmed efficacy and safety from clinical trials. This document summarizes outstanding references for allergic immunotherapy decision-making and provides summary tables and figures analyzing the most important factors related to the decision for allergen immunotherapy and the safety risks related. The experts concluded that AIT is efficacious and safe for the treatment of allergic patients that is available for the most frequent aeroallergens.What is Known:• The prevalence of allergic asthma and rhinitis in children has increased in recent decades.• The efficacy and safety of allergen immunotherapy has been shown in multiple studies and systematic reviews.What is New:• This document summarizes outstanding references for allergic immunotherapy decision-making and provides summary tables and figures analyzing the most important factors related to the decision for allergen immunotherapy and the safety risks related. Recommendations of expert authors for the decision of the patients more suitable for allergen immunotherapy are included.
