Subject. The subject of the study is the cytokine profile of saliva in violation of mucosal immunity in patients with chronic generalized periodontitis and concomitant type II diabetes mellitus. Objectives. The goal was to assess local levels of cytokines: tumor necrosis factor-alpha (TNF-α), interferon-gamma (IFN-γ), transforming growth factor-beta 1 (TGF-β1), interleukin-4 (IL-4), interleukin-17 (IL-17) in patients with chronic generalized periodontitis without concomitant pathology (group I), with chronic generalized periodontitis and type II diabetes mellitus (group II), as well as in patients without signs of periodontitis, but with established type II diabetes mellitus ( III group). Methodology. 126 patients were examined, including: 47 people – group I, 49 people – group II and 30 people – group III. The control group consisted of healthy volunteers (30 people). Patient saliva was used as the research material. The levels of the studied cytokines TNF-α, IFN-γ, TGF-β1, IL-4, IL-17 were determined by the sandwich variant of enzyme-linked immunosorbent assay using specific reagents from R&D Diagnostics Inc (USA). Results. In patients of all studied groups, a significant increase in TNF-α, IFN-γ, IL-4 and IL-17 was found. In the group of patients with chronic periodontitis, a more pronounced increase in TNF-α, IFN-γ, TGF-β1 and IL-17, as well as an increase in the ratio of pro- and anti-inflammatory cytokines, was registered. Conclusion. The data obtained can be considered as promising markers for the personification of the prognosis for the development of chronic generalized periodontitis in type II diabetes mellitus.
