The importance of mold sensitivity in nonallergic rhinitis patients

Abstract

BackgroundIn recent studies, local specific immunoglobulin E (sIgE) production against allergens in nasal mucosa and a positive response to a nasal allergen provocation test (NAPT) have been demonstrated in some patients initially diagnosed as nonallergic rhinitis (NAR) or idiopathic rhinitis (IR). The aim of this study was to evaluate the presence of local allergic rhinitis (LAR) in patients who experience rhinitis symptoms in indoor and outdoor moldy conditions and to investigate the role of the NAPT in diagnosis.
