Clinical and microbiological peculiarities of nose pathology and paranasal sinuses in patients with non-hospital pneumonia.

This article presents the results of a comprehensive otorhinolaryngological and microbiological study of diseases of the nose and paranasal sinuses in patients with community-acquired pneumonia. These diseases are closely interconnected, since the upper and lower respiratory tract are a single whole, have structures and functions and mechanisms for the development of pathological conditions. The etiopathogenesis of bacterial inflammatory diseases of the upper and lower respiratory tract is based on the violation of the integrity of epithelial cells under the influence of respiratory viruses. Under the influence of the general toxic effect of the virus, phagocytosis is inhibited, immunological protection is disrupted, as a result, favorable conditions are created for microbial colonization in the nasopharynx and the further spread of infections to the paranasal sinuses and lower respiratory tract. As a result of a clinical and microbiological study, it was revealed that in community-acquired pneumonia, inflammatory diseases of the nose and paranasal sinuses such as acute and chronic rhinosinusitis, allergic and vasomotor rhinitis, curvature of the nasal septum were often encountered. To determine the nature of the microbial landsURTe of the upper and lower respiratory tract, a comparative microbiological analysis was performed from the nose and sputum. Analyzes showed that there was no significant difference in pathogenic microflora between the upper and lower respiratory tract. The main pathogen in both diseases was Streptococcus pneumoniae. Correspondence of the pathogenic microflora of the nasal cavity and lower respiratory tract when rhinosinusitis is detected in patients with community-acquired pneumonia confirms the pathogenetic relationship of inflammatory processes in these organs, as well as the need for parallel diagnosis, treatment, prevention.
