Dependence of hematological parameters on the microbiota of the nasal mucosa in chronic rhinitis

Abstract

Relevance. Chronic rhinitis is one of the most common otorhinolaryngological diseases. We assume that dysbiosis of the nasal mucosa depends on the phenotype of chronic rhinitis and affects hematological characteristics. Aim. Study of the hematological parameters dependence from the microbiota of the nasal mucosa in patients with various forms of chronic rhinitis. Material and methods. The examination groups included 45 patients with chronic allergic rhinitis (CAlR), 49 patients with chronic vasomotor rhinitis (CVR), 32 patients with chronic atrophic rhinitis (CAR), 39 patients with chronic infectious rhinitis (CIR) and 40 people from the control group. The subjects with chronic rhinitis, as well as the control group, underwent bacteriological examination of the nasal mucosa and assessment of hematological parameters. Statistical analysis was carried out using the Statistica 10 package. Results. The microbiome of the nasal mucosa is characterized by 100% infection with infectious agents in CIR, while fungal flora was detected in 1/3 of cases. The microbiological features of the nasal mucosa in CVR corresponded to the control, in CAR rhinitis - predominantly the growth of Klebsiella spp., in CIR - Staphylococcus spp., Streptococcus spp., Neisseriae spp., Escherichia spp. Hematological features manifested themselves depending on the form of chronic rhinitis. The greatest number of changes in blood parameters is found in CIR and CAR, less in CAlR, no changes were detected in CVR. The greatest dysbiosis of the nasal mucosa in CIR, the abundant growth of microorganisms of the genus Klebsiella spp in CAR corresponds to the largest number of changes in hematological parameters, and CVR is characterized by the absence of changes in hematological parameters, despite the fact that the microbiological characteristics of the nasal mucosa corresponded to the control. Conclusion. The microbiota of the nasal mucosa in healthy people and patients from the groups with CAlR, CVR and CAR is represented by a combination of coccal and rod-shaped flora, with the exception of CIR, in which representatives of the fungal flora are identified. Pathogenetically significant is the identification of representatives of Staphylococcus spp., Streptococcus spp., Neisseriae spp., Escherichia spp. in CIR, and Klebsiella spp. in CAR. Most hematological changes are detected in chronic atrophic and infectious rhinitis.
