Seasonal Oxidative Stress and Airway Reactivity in Rhinitis: Distinct Patterns in Allergic vs. Non-allergic Individuals

Seasonal air pollution exerts phenotype-specific effects on oxidative stress and airway reactivity in rhinitis. AR patients exhibited increased bronchial hyperresponsiveness, whereas NAR individuals showed a marked decline in antioxidant capacity. These findings highlight the importance of phenotype-based monitoring and management during periods of high environmental exposure.
