Seasonal and perennial allergic rhinitis: is this classification adherent to real life?

Background:  Allergic rhinitis is traditionally subdivided into seasonal (SAR) and perennial (PAR), although the new definitions of persistent and intermittent were recently proposed. We assessed the validity of the traditional classification in a large group of subjects suffering from allergic rhin...

Description
Summary:Background:  Allergic rhinitis is traditionally subdivided into seasonal (SAR) and perennial (PAR), although the new definitions of persistent and intermittent were recently proposed. We assessed the validity of the traditional classification in a large group of subjects suffering from allergic rhinitis alone. Methods:  Young males referred to a Navy Military Hospital for routine fitness visit, and reporting symptoms of rhinitis alone were selected. According to the sensitization they were subdivided into (i) sensitized to pollens only (seasonal, SAR), (ii) to perennial allergens only (perennial, PAR) and (iii) to both (mixed, MAR). Spirometry, methacholine challenge, severity and characteristics of symptoms were assessed in all participants. Results:  Of 19 325 subjects, 2347 had allergic rhinitis. Seventy‐two percent of the subjects had MAR, 17% SAR and 11% PAR. Ocular involvement and irritative symptoms were more frequent in SAR (P
