title: [Pathogenesis and clinical features of polypous rhinosinusitis].
abstract: The paper presents recommendations of the current European and Russian documents concerning pathogenesis of polypous rhinosinusitis (International Consensus Conference on Nasal Polyposis (2006), European documents EAACI - EP3OS (2007), and Summit of the Russian Society of Rhinologists "Nasal polyposis and inflammation" (2009)). The bilateral polypous process in the nasal cavity is considered to be a "special form of rhinosinusitis" in which bacterial superantigens or fungal infection induce chronic eosinophilic inflammation. Researchers of the ENT Department, Rostov State Medical University, undertook analysis of the results of long-term comprehensive examination of patients with polypous rhinosinusitis that included clinical, bacteriological, histomorphological, and allergological studies as well as evaluation of local and systemic immunity. The data obtained allowed to describe one of the forms of polypous rhinosinusitis as chronic infection-dependent allergic rhinosinusitis with the manifestation of all four types of allergic reactions, formation of the autoimmune component, and development of persistent immune inflammation leading to remodeling of endonasal mucosa. In all these cases, the process progressed parallel to the development of combined secondary immune deficiency (SID). A hypothetical scheme of pathogenesis of chronic polypous allergic rhinosinusitis is proposed.
