The effects of systemic, topical, and intralesional steroid treatments on apoptosis level of nasal polyps.
2012
ObjectiveThe purpose of this study was to compare the apoptotic responses to systemic, topical, and intrapolyp injection of glucocorticoid with no treatment in nasal polyps.Study DesignProspective, randomized controlled study.SettingTertiary training hospital.Subjects and MethodsThe study was performed on 48 patients with nasal polyposis in the Department of Otorhinolaryngology between 2008 and 2009. Patients were assigned to 1 of 4 groups of 12 patients. Group A was treated with oral methylprednisolone 1 mg/kg/d, and the dose was tapered gradually. Group B received 0.3 mL triamcinolone acetonide (40 mg/mL), which was injected into polyp tissue. Group C was treated with topical 55 µg triamcinolone acetonide 2 times daily for 1 month. Group D received no medication. Samples were collected endoscopically after the seventh day for groups A and B, the first month for group C, and the first visit for group D. Apoptotic indexes were determined using the terminal deoxynucleotidyl transferase-mediated dUTP nick e...
