Abstract
Chronic nasopharyngitis (CNP) and chronic rhinosinusitis (CRS) are both common diseases that affect the quality of life and making secondary pathology, especially in children. The clinical symptoms of CNP and CRS mostly coincide, and the pathogenesis in both cases is based on chronic inflammation. Despite the fact that the pathogenetic role of bacterial infection in these processes development has not been proven, there is a hypothesis that changes in the upper respiratory tract microbiome play a significant role in the development of these diseases.
The article presents a review of current ideas about the role of the microbiome and bacterial biofilms in the pathogenesis of CNP and CRS. The key etiopathogenetic mechanisms are considered, including immune dysfunction of the mucosal barrier, microbial dysbiosis, and the formation of biofilms that contribute to the persistence of inflammation. The focus is on the ineffectiveness of systemic antibiotic therapy in the fight against biofilms, which necessitates the search for alternative approaches. A separate section is devoted to the possibilities of intranasal administration of antibiotics, in particular framycetin solution (Izofra nasal spray), as a promising and safe strategy for local therapy.
The authors emphasize the need for further clinical studies to optimize treatment tactics for CNF and CRS, taking into account the need to influence the microbial component of the complex pathogenesis of chronic inflammation.
