Abstract
The number of Japanese cedar and/or cypress pollinosis patients has been clearly increasing. Not only nasal symptoms but also pharyngo-symptoms impair the QOL of pollinosis patients. In this study, the correlations with coughs and the other symptoms with the QOL, were studied. Four thousand, seven hundred and sixty-five patients with seasonal allergic rhinitis were enrolled in the Osaka area as subjects in this study. Thirty-nine point nine percent of patients had a cough: 49.7% of those began to cough with pollen scattering and 33.6% of them began to cough during the pollen scattering peak period. Moreover in 52.0% of those patients with a cough, the coughing became most severe during the scattering peak. The onset of coughing showed the highest correlation with nasal obstruction and/or mouth respiration with obstruction, so it seemed that nasal obstruction participated as an exacerbating factor of the cough in pollinosis patients.
