A survey of allergic rhinitis in Taiwanese asthma patients.

Background: Allergic rhinitis (AR) often coexists with and can significantly worsen bronchial asthma (BA). We evaluated the proportion of patients with BA and concomitant AR (BA+AR) diagnosed and treated in an average clinical practice.

Methods: A cross-sectional study methodology was used to determine the prevalence of AR in patients more than 15 years of age with a documented history of asthma who experienced wheezing during the prior 12 months.
