RESUMO
Allergies and asthma are common diseases in most parts of the world. Together, they represent a major burden on global health, as well as on health costs. However, efficient preventive measures are still lacking, and treatments are mostly symptomatic. The pathogenesis of the "allergic marathon'', the progression of the disease throughout childhood into adulthood is only partly understood. In addition, treatment protocols addressing the pathogenesis of the disease are not available to all patients, either due to economical reasons, or to insufficient efficacy or safety of the procedures. This editorial introduces a supplement dedicated to identify directions and means to fight the burden of allergies in childhood. This initiative is coordinated by iPAC (international Pediatric Allergy and Asthma Consortium).
