Integrated Approach to Pediatric Asthma Allergic Rhinitis and Atopic Multimorbidity

Abstract

Asthma and allergic diseases are among the most common chronic disorders in childhood and adolescence, producing a substantial burden through recurrent symptoms, school absenteeism, impaired sleep, emergency visits and reduced quality of life. Traditionally, bronchial asthma, allergic rhinitis, atopic dermatitis and food allergy have often been evaluated as separate conditions. However, growing clinical and immunological evidence supports a more integrated concept of “united airway disease” and atopic multimorbidity, in which upper and lower airway inflammation, epithelial barrier dysfunction, type 2 immune responses and environmental exposures interact across childhood. Allergic rhinitis is particularly important because it frequently coexists with asthma, worsens asthma control and may precede lower airway disease. This review summarizes current evidence on the epidemiology, pathophysiology, diagnosis and management of pediatric asthma associated with allergic rhinitis and other allergic disorders. Special attention is given to early-life risk factors, the atopic march, type 2 inflammation, allergen sensitization, air pollution, climate change, diagnostic tools, inhaled corticosteroid-based treatment, allergen immunotherapy and biologic therapy for severe asthma. The review emphasizes that optimal care requires systematic assessment of comorbid allergic rhinitis, inhaler technique, adherence, environmental triggers and individualized risk of exacerbations. Integrated management may improve asthma control, reduce medication burden and prevent disease progression in selected children. Future research should prioritize phenotype-based studies, locally adapted diagnostic algorithms, real-world evidence on biologics and immunotherapy, and prevention strategies targeting environmental and social determinants of pediatric allergic disease.
