Study of microbial factors in exacerbation of chronic rhinosinusitis with nasal polyps

Abstract

Introduction. Chronic rhinosinusitis with nasal polyps (CRSwNP) is considered a multifactorial disease. There are data on the contribution of fungi and viruses to the initiation and development of the inflammatory process, data on the effect of superantigens, biofilms and microbiota on the growth of polyps in the paranasal sinuses. Exacerbation of the disease in patients with CRSwNP leads to a significant decrease in the quality of life. Aim. To study the bacterial component of the microbiota of nasal and paranasal mucosa in patients with CRSwNP during remission and exacerbation. Materials and methods. 83 patients with CRSwNP were examined (44 patients in remission, 39 people in the period of exacerbation of the disease). A qualitative and quantitative analysis of bacterial component of the microbiota in all patients were carried out. Results. No significant differences in the qualitative and quantitative composition of the nasal cavity microbiota during exacerbation and remission of inflammatory process were observed, as well as before and after treatment of the CRSwNP exacerbation. The quantitative assessment of the identified microorganisms in the vast majority of cases was within the normal range.
