Synopsis:
This study estimated the prevalence of patients with AERD in the total group of patients with nasal polyps, as well as a statistically significant difference between these two groups regarding: the size of nasal polyps before and after the administration of corticosteroid therapy; the number of repetitions of required systemic corticosteroid therapy for one year, as well as decisions about patients’ need for surgical treatment after corticosteroid therapy for one year.
