DISEASE PHENOTYPE-DRIVEN ALTERATIONS IN CELLULAR AND HUMORAL IMMUNITY DURING CHRONIC RHINOSINUSITIS

Abstract

Abstract Human nasal cavity and paranasal sinuses play a crucial role in the physiological processes in vivo that accounts for the constant attention of doctors of many specialties to the state and pathological changes in the respiratory compartments noted above. Rhinosinusites hold one of the leading places in the pattern of inflammatory pathology of the paranasal sinuses, regardless of patient age, the climatic zone of residence and living style level. Chronic vs. acute rhinosinusitis is less widespread but considered to be the most common chronic disease. This pathology develops on average in 5% population, and CRS incidence increased more than by 2-fold over the last 10 years. In the pattern of subjects admitted to otorhinolaryngological hospitals, CRS comprises 25-30% that progressively elevates by mean 1-2% every year. The aim of the study was to evaluate disease phenotype-driven alterations in cellular and humoral immunity in patients with chronic rhinosinusitis. 91 patients with chronic rhinosinusitis were selected. For the study of cellular immunity, a flow cytometry was used with Cytomics FC500 (Beckman coulter, USA) and monoclonal antibodies: CD3+, CD4+, CD8+, CD16+, CD19+ (Beckman Coulter). To measure the levels of blood serum immunoglobulins of various classes (A, M, E, G), an enzyme-linked immunosorbent analysis (ELISA) was used. Statistical data processing was carried out using Statistica for Windows 8.0 application programs (StatSoftink., USA, 2008). The study revealed changes in the cellular and humoral links of immunity in chronic rhinosinusitis coupled to distinct disease phenotypes: with chronic allergic rhinosinusitis - 5; in chronic polypose rhinosinusitis - 4; in chronic infectious rhinosinusitis - 3; In chronic hyperplastic rhinosinusitis - 4. With allergic chronic rhinosinusitis, it was linked to higher absolute B-lymphocyte count, hypergammaglobulinemia E and a decrease in 3 indices of relative synthesis were revealed. Polypose chronic rhinosinusitis was associated with elevated in absolute B-lymphocyte level, hypergammaglobulinemia E and decrease in 2 indices of relative synthesis, whereas infectious chronic rhinosinusitis was accompanied by increased B-lymphocyte level and decrease in 2 indices of relative synthesis. Hyperplastic chronic rhinosinusitis patients had higher in absolute T- and B-lymphocyte count and a decreased absolute cytotoxic T-lymphocyte level along with 2 indices of relative synthesis.
