Abstract
Introduction. Today, there are lot of theories of pathogenesis of polypoid sinusitis. The contribution of Starchylocossus aureus (S. aureus) to the occurrence of this pathogenetic reaction is being actively discussed.Objective: to improve the effectiveness of treatment of polypoid sinusitis using the results of the study of the effect of persistent staphylococcal infection on the onset and course of the disease.Materials and methods. The authors examined 105 patients with recurrent polyposis sinusitis aged 20 to 65 years. All patients underwent FESS surgery for recurrent polypous sinusitis at the initial visit. In the postoperative period, all patients received treatment according to one of two schemes. The first scheme included antihistamines and topical steroids, the second additionally included clarithromycin. The patients underwent bacteriological examination of smears for flora and fungi from the cavity; cytological examination of smears-prints from the mucous membrane of the nasal cavity (we counted neutrophils, eosinophils and lymphocytes in the preparation); immunological and allergic examination (skin tests, serum specific IgE levels).Results and discussion. It has been established that the presence of a carriage and sensitization to S. aureus in a patient, especially in combination with atopy, results in a more severe course of polyposis sinusitis severe nasal obstruction (91% versus 69.5%, respectively) and is characterized by more pronounced eosinophilic inflammation than Polypoid Sinusitis associated with infection with other microorganisms (the number of eosinophils in the blood: 7.5% and 4.3%, respectively; the level of eosinophils in smears from the nasal mucosa is 13 and 4.8%, respectively; the average ECP level is 17.6 and 8.1 ug / ml, respectively).Conclusions. The use of topical GCS remains one of the leading methods for preventing recurrence of PS. However, in addition to the backbone therapy with topical GCS and antihistamines, it is advisable to complete a course of antibiotics during nasal colonization with S. aureus.
