Objective:
Management of nasal polyposis should be primarily medical. Resorting to intranasal ethmoidectomy should not be envisaged before a trial of dual steroid therapy. Nevertheless, no risk factor for steroid insensitivity in patients with nasal polyposis is actually defined. The aim of this study is to evaluate whether the presence of asthma and/or non-specific bronchial hyperresponsiveness (BHR) can be considered a risk factor for steroid insensitivity.
Material And Methods:
This study focused on the evaluation of a dual modality, topical and systemic, over a follow-up period of 3 years. A total of 55 subjects with and 45 subjects without BHR were treated according to a standardized therapeutic protocol combining short-term oral administration of prednisolone and a daily intranasal spray of beclomethasone.
Results:
Over the follow-up period of 3 years, this dual modality proved to be successful in 93.4% of subjects without BHR and without aspirin idiosyncrasy, in 82.2% of subjects with BHR and without aspirin idiosyncrasy and in 60% of subjects with BHR and aspirin idiosyncrasy. The percentage of patients who underwent surgery after the failure of medical treatment was significantly larger in patients with than without BHR (p < 0.05) and in patients with than without aspirin idiosyncrasy (p < 0.02).
Conclusion:
The presence of BHR and/or aspirin idiosyncrasy can be considered a major risk factor for steroid insensitivity in patients with nasal polyposis.
