    Abstract : In allergic or asthmatic airways disease, upper and lower airways show a uniform eosinophilic inflammation of the mucosa, and bronchial hyperreactivity is a common finding. To study the co- variation of mucosal reactivity in upper and lower airways, histamine challenges of both sites were performed in a group of patients with allergic rhinitis during non-season.
