Summary
The purpose of this study is to prospectively examine the relation between topical
corticosteroid use and hair cortisol concentration, among patients with moderate persistent
asthma or allergic rhinitis. The investigators hypothesize that patients with asthma or
allergic rhinitis treated with topical corticosteroids (i.e. inhaled corticosteroids (ICS) or
intranasal glucocorticoids (INGC)) have higher levels of hair cortisol after 3 months of
treatment than during the 3 months prior to initiation of treatment.
