Non-allergic rhinitis is a distinct disease classification, separate from allergic rhinitis, which is characterized by an IgE-mediated response. The diagnosis of non-allergic rhinitis encompasses several individual classifications, including NARES, as well as vasomotor, occupational, hormonal, infectious, drug-induced, and gustatory conditions. The prevalence of rhinitis symptoms in the International Study on Asthma and Allergies in Childhood (ISAAC) varied between 0.8% and 14.9% in 6-7 year olds and between 1.4% and 39.7% in 13-14 year olds. Countries with a very low prevalence include Indonesia, Albania, Romania, Georgia and Greece. Countries with a very high prevalence include Australia, New Zealand and the United Kingdom.
Avoidance of inciting factors such as sudden in temperature, humidity, blasts of air or dust.Intranasal corticosteroids and intranasal antihistamines are useful. Non-allergic rhinitis of all types is rare in children, and is poorly understood. The true incidence in children are unknown. Children presenting with NARES account for less than 2% of children with nasal eosinophilia. Although growth delay has not been observed in long-term studies, the FDA recommends routine monitoring of height in children treated with corticosteroids. Effects of laryngopharyngeal reflux (LPR) have been implicated in some sinonasal diseases in children and should be considered by the clinician.
