After this early study, patients were divided into 3 groups: group I: patients without brochial hyperreactivity (HRB (-)) without sensitivity to AAS (AAS(-)); Group II: patients HRG (+) AAS (-); Group III: patients HRG(+) AAS(+). Those patients with previous rhinoscopy and with hyperreactivity to metacholine were examined monthly during one year: their symptoms and medication, 3 patients from group II and 3 from Group III were selected.
