Comparative analysis of allergic rhinitis in children and adults

Abstract

Allergic rhinitis (AR) is a worldwide health problem that generates a significant healthcare burden in adults, adolescents, and children. Epidemiological studies have indicated that the prevalence of AR has progressively increased over the last three decades in developed and industrialized countries. AR currently affects up to 40 % of the worldwide population, with differences between adults and children and different countries of the World. Although not life-threatening, AR symptoms are frequently bothersome, adversely affecting work and quality of life of the affected patients, and causing a significant burden on both the individual and society. The symptoms have the potential to lead to both physical and mental complications, with sleep-disordered breathing in childhood and adolescence being associated with disorders in learning performance, behavior, and attention. Clinical features and comorbidities are very important for the "allergic march", and in both adults and children there is some evidence of association between AR and asthma. ARIA classifications of both symptom duration (intermittent, persistent) and severity (mild, moderate, severe) have been validated in both adult and pediatric populations. Based on the duration and severity of patient's disease, an appropriate treatment strategy has been issued for both adults and children, which consists of patient's education, allergen avoidance, and pharmacological as well as allergen-specific immunotherapy treatment. The present review will attempt to compare the characteristics of AR between children and adults, either in the epidemiology, clinical features, impact on QOL, and management of the disease. © 2012 Springer Science+Business Media New York.
