Airway response of asthmatic subjects to inhaled allergen after exposure to pollutants.

Abstract

These results demonstrate that exposure to a combination of NO2 and SO2, at concentrations which can be encountered during episodes of increased outdoor and indoor air pollution, enhances the airway response to inhaled allergen in asthmatic subjects. This effect persists over a period of 24-48 hours and is maximal 24 hours after exposure to these air pollutants.
