Nonallergic rhinitis is the inflammation of the nasal lining membranes without any immunoglobulin E mediation, as documented by allergen skin testing.
Major signs and symptoms include nasal itching, watery rhinorrhea, nasal obstruction/congestion, sneezing and postnasal drainage.
Symptoms can reverse spontaneously with or without treatment.
Infants with persistent rhinitis have a higher abundance of Actinobacteria, especially Corynebacterium spp., in their nasal microbiome compared with healthy controls, according to a Singapore-based study presented at the European Academy of Allergy and Clinical Immunology (EAACI) Annual Congress 2016 held in Vienna, Austria.
