Cytokine Levels In Gingival Fluid Research Articles

Diagnostic information content of indicators of cytokine profile of gingival fluid in pregnant women with iron deficiency anemia

Relevance. Modern literature and clinical dental practice do not provide enough information about the value of local immunity parameters for early diagnosis of inflammatory periodontal diseases in pregnant women with iron deficiency anemia. Conventional anti-inflammatory medications used to treat inflammatory periodontal disease are frequently contraindicated during pregnancy. It is important to make a reasonable choice of safe medications, prevention methods, and treatment at early stages of inflammatory periodontal diseases in pregnant women with iron deficiency anemia. The aim of the present study is to determine informative cytokine levels in gingival fluid for early diagnosis of inflammatory periodontal disease and evaluation of effectiveness of “Lysobact” medication in pregnant women with iron deficiency anemia (IDA).Materials and methods. Cytokine levels (IL-8, IL-10; IgA, IgG) in gingival crevicular fluid were investigated in 46 pregnant women aged 18-35: among them 16 (n = 16) had mild IDA (D50), 15 (n = 15) didn't have IDA, 15 (n = 15) were non-pregnant controls. «Lysobact» (Reg. #ПN0179/01-2002) was used in pregnant women with IDA; conventional antiinflammatory therapy was used to treat pregnant women without IDA, before and after drug therapy (8-10 days) according to clinical examinations.Results. There was determined diagnostic value of cytokine levels (IgA, IgG; IL-8, IL-10) that are of great importance for early diagnosis, evaluation of the course of the disease and effectiveness of “Lysobact” immunomodulating drug, and that significantly increase in pregnant women with IDA (IL-10 from 0.010 [1.790] to 3.050 [8.550] ng/ml) versus pregnant women without IDA (from 0.001 [1.259] to 2.900 [18.640] ng/ml) in comparison with controls (4.5 [1.13] ng/ml).Conclusion. Clinical laboratory results in pregnant women with inflammatory periodontal disease allowed to determine diagnostic value of gingival crevicular fluid parameters (sIgA, IgG; IL-8, IL-10) that are related to clinical periodontal index levels, and are informative non-invasive method and are of practical importance for early diagnosis of inflammatory periodontal disease and effectiveness of “Lysobact” drug in pregnant women with iron deficiency anemia.

Interleukin-1α and -1β assessment in the gingival crevicular fluid of periodontal patients with chronic hepatitis C.

The study assessed whether the increased production of interleukin-1α (IL-1α) and interleukin-1β (IL-1β), as a result of chronic hepatic inflammation, could be the expression of the negative impact on periodontal disease. The study included chronic periodontitis patients who were systemically healthy, chronic periodontitis patients suffering from chronic hepatitis C, as well as control patients, being systemically and periodontally healthy. After periodontal examination and the assessment of certain periodontal parameters, gingival crevicular fluid was collected from all participating patients. By using the enzyme-linked immunosorbent assay method, a quantitative assessment of IL-1α and IL-1β levels was possible. The immunologic results were correlated to the clinical periodontal data. The gingival fluid levels of cytokines were higher for periodontitis patients with chronic hepatitis C than for the systemically healthy periodontitis patients (1.8-fold higher for IL-1α and 2.1-fold higher for IL-1β). In addition, the gingival fluid cytokine levels were significantly higher for the periodontal patients (with/without chronic hepatitis C) than for the control group. Positive correlations were found between gingival fluid IL-1α and IL-1β levels and certain clinical periodontal parameters or the age of the viral hepatitis C diagnosis, in periodontitis patients with chronic hepatitis C. The chronic hepatic inflammation may have an important additional negative impact on the periodontal status, as both inflammatory reactions seem to be promoted by common pro-inflammatory cytokines.
