Objectives: We attempted to determine whether inflammation is present in induced sputum

Methods: Sputum was induced in 30 patients with seasonal rhinitis in response to grass
pollens only and in 15 patients with stable, asymptomatic asthma. The AR group was
divided according to methacholine PD20 value: the AR–group (n= 15) had a methacholine …
