Abstract

BACKGROUND: There has been little investigation regarding air quality and rhinitis in the pathophysiology of upper airway disease. In this study, we assessed the impact of inhalant pollutants (particulate matter 2.5 [PM

METHODS: CRS patients with nasal polyps (CRSwNP) and without polyps (CRSsNP) were identified. Spatial modeling from pollutant monitoring sites was used to estimate exposures for patients meeting the inclusion criteria (total, n = 125; CRSsNP, n = 67; CRSsNP, n = 58). Skin-prick, intradermal dilutional, and in-vitro testing methods were utilized to determine aeroallergen sensitization. Disease severity indicators were measured by modified Lund-Mackay score (LMS), the 22-item Sino-Nasal Outcome Test (SNOT-22), systemic steroid therapy, and number of functional endoscopic sinus surgeries (FESS).

RESULTS: Thirty-six percent (n = 45) of patients who described rhinitis symptoms demonstrated no reactivity to aeroallergen testing. Sixty-four percent (n = 80) tested positive for at least 1 allergen, with no differences found between CRSsNP and CRSwNP (62.1% vs 67.2%). There were significant differences in air pollutants between patients testing negative and positive for allergies (nonallergic vs allergic: PM

CONCLUSION: Our results suggest that small inhalant pollutants may contribute to nonallergic symptomatology in patients with and without nasal polyps. Regardless of allergy status, BC may play a role in CRS symptom severity.
