    Gingival crevicular fluid and plasma acute-phase cytokine levels in different periodontal diseases
    (2012) Becerik S.; Öztürk V.O.; Atmaca H.; Atilla G.; Emingil G.
    Background: The aim of the present study is to investigate gingival crevicular fluid (GCF) and plasma acute-phase cytokines, interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-11 (IL-11), oncostatin M (OSM), and leukemia inhibitory factor (LIF) levels in patientswith different periodontal diseases. Methods: Eighty individuals were included in this study; 20 with chronic periodontitis (CP), 20 with generalized aggressive periodontitis (GAgP), 20 with gingivitis, and 20 classified as healthy (H). Probing depth, clinical attachment level, plaque index, and papilla bleeding index were recorded. Plasma and GCF IL-1β, IL-6, IL-11, OSM, and LIF levels were analyzed by enzyme-linked immunosorbent assay. Results: CP and GAgP groups had significantly higher GCF IL-1β, IL-6, and IL-11 levels when compared with the H group (P <0.05). Conversely, GCF LIF levels of the CP and GAgP groups were lower than those of the H group (P <0.05). GCF OSM levels did not differ significantly among study groups. Plasma levels of all the cytokines studied were not significantly different among the study groups. Conclusions: Based on the present data, elevated IL-1β, IL-6, and IL-11 GCF levels, but not plasma levels, are suggested as reliable inflammatory biomarkers in periodontal diseases. Decreased LIF levels in diseased groups might reflect the possible beneficial effects of LIF in the modulation of inflammatory response in gingiva.

    Gingival crevicular fluid interleukin-36β (-1F8), interleukin-36γ (-1F9) and interleukin-33 (-1F11) levels in different periodontal disease
    (Elsevier Ltd, 2014) Kurşunlu S.F.; Öztürk V.Ö.; Han B.; Atmaca H.; Emingil G.
    Background Periodontal inflammation is driven by the coordinated action of a number of factors, including the IL-1 family. Our study aimed to examine the levels of interleukin (IL)-36β, IL-36γ and IL-33 levels in gingival crevicular fluid (GCF) from patients with different periodontal diseases. Materials and methods A total of 80 subjects, 20 patients with generalized aggressive periodontitis (G-AgP), 20 patients with chronic periodontitis (CP), 20 with gingivitis and 20 periodontally healthy subjects were included. Periodontal status was evaluated by measuring probing depth, clinical attachment loss, papillary bleeding index and plaque index. GCF cytokine levels were analysed by ELISA. Results CP, gingivitis and healthy groups had similar GCF IL-36β total amount (p > 0.008). G-AgP group had elevated IL-36β total amount compared to CP group (p < 0.008). G-AgP group had similar GCF IL-36β total amount to gingivitis and healthy groups (p > 0.008). GCF IL-36γ and IL-33 total amounts of the study groups were similar (p > 0.05). Conclusions The present study demonstrated for the first time the presence of IL-36β, IL-36γ and IL-33 GCF levels with different periodontal diseases. High levels of IL-36-β in the AgP group in comparison to CP group might suggest that periodontitis in the aggressive form could be related to the increase in GCF IL-36β. © 2014 Elsevier Ltd.

    Evaluation of gingival crevicular fluid cyclophilin a and extracellular matrix metalloproteinase inducer levels in different periodontal diseases
    (Elsevier Ltd, 2016) Eren G.; Türkoǧlu O.; Atmaca H.; Atilla G.
    Objective Cyclophilin A (CypA) is able to regulate inflammatory responses and matrix metalloproteinase production via its interaction with extracellular matrix metalloproteinase inducer (EMMPRIN). EMMPRIN is the cell surface receptor of CypA. The aim of the present study was to evaluate the gingival crevicular fluid (GCF) CypA and EMMPRIN levels in patients with chronic periodontitis (CP), generalized aggressive periodontitis (G-AgP) and periodontally healthy controls. Methods Twenty CP patients, 19 G-AgP patients and 20 healthy control subjects were included in the present study. All study participants were non-smokers. Full mouth clinical periodontal parameters including probing depth, clinical attachment level, plaque index, and papilla bleeding index were recorded. GCF CypA and EMMPRIN levels were analyzed by enzyme-linked immunosorbent assay. Data were analyzed statistically with parametric and non-parametric tests. Results GCF CypA total amount was higher in the G-AgP group compared to healthy controls (p < 0.05), whereas CypA total amounts were similar in CP and healthy controls (p > 0.05). No significant difference in GCF CypA total amount between CP and G-AgP was observed (p > 0.05). Also, there was no significant difference in GCF EMMPRIN total amounts among the study groups (p > 0.05). Conclusion Higher levels of GCF CypA in patients with G-AgP might demonstrate that CypA is associated with the inflammatory infiltrate and alveolar bone destruction of G-AgP. However, GCF CypA level does not seem to be affected by CP. Similar GCF EMMPRIN levels in diseased and healthy groups might suggest that EMMPRIN has role in the turn over of connective tissues in physiological conditions as well as pathological state. © 2016 Elsevier Ltd.

    Gingival crevicular fluid and serum hCAP18/LL-37 levels in generalized aggressive periodontitis
    (Springer Verlag, 2017) Turkoglu O.; Emingil G.; Eren G.; Atmaca H.; Kutukculer N.; Atilla G.
    Objectives: hCAP18/LL-37 is an endogenous antibiotic having a role in innate immunity. The aim of the present study was to evaluate serum and gingival crevicular fluid (GCF) hCAP18/LL-37 levels in patients with generalized aggressive periodontitis (G-AgP). Materials and methods: Twenty-six G-AgP patients, 24 gingivitis patients, and 25 healthy subjects were included in this study. Periodontal parameters including probing depth, clinical attachment level, plaque index, and papilla bleeding index were recorded. GCF and serum hCAP18/LL-37 levels were analyzed by enzyme-linked immunosorbent assay. Results: GCF hCAP18/LL-37 level was significantly higher in G-AgP compared to others (p = 0.038, p < 0.001). Gingivitis patients had significantly higher GCF hCAP18/LL-37 levels than controls (p < 0.001). No significant differences were observed in serum hCAP18/LL-37 levels among the study groups (p = 0.524). While there were positive correlations between GCF hCAP18/LL-37 levels and periodontal parameters of sampling sites (p < 0.005), no significant correlation was observed between serum hCAP18/LL-37 levels and whole-mouth periodontal parameters (p > 0.05). Conclusion: Increased levels of GCF hCAP18/LL-37 in G-AgP might show that it is abundantly expressed in the presence of periodontal tissue destruction. Serum hCAP18/LL-37 levels do not seem to be related with the presence of G-AgP. Clinical relevance: hCAP18/LL-37 antimicrobial peptide might be associated with periodontal tissue destruction in the presence of aggressive periodontitis. © 2016, Springer-Verlag Berlin Heidelberg.

    Gingival crevicular fluid and salivary HIF-1α, VEGF, and TNF-α levels in periodontal health and disease
    (Wiley-Blackwell, 2019) Afacan B.; Öztürk V.Ö.; Paşalı Ç.; Bozkurt E.; Köse T.; Emingil G.
    Background: Hypoxia-inducible factor-1 alpha (HIF-1α) is expressed as an adaptive response to hypoxia, mediates angiogenesis through the expression of vascular endothelial growth factor (VEGF) and can be induced by tumor necrosis factor-alpha (TNF-α). This study aimed to investigate the gingival crevicular fluid (GCF) and salivary HIF-1α, VEGF, and TNF-α levels in periodontal health and disease. Methods: A total of 87 individuals, 20 generalized aggressive periodontitis (G-AgP), 20 chronic periodontitis (CP), 26 gingivitis patients, and 21 periodontally healthy individuals, were included. Clinical periodontal parameters were recorded; GCF and salivary samples were collected; and HIF-1α, VEGF, and TNF-α levels were measured by enzyme-linked immunosorbent assay. Nonparametric tests were used for the statistical analyses. Results: G-AgP and CP groups had significantly higher GCF HIF-1α, VEGF, and TNF-α total amounts than gingivitis and healthy groups (P < 0.05). GCF HIF-1α and TNF-α total amounts in gingivitis group were significantly higher than the healthy group (P < 0.05). GCF and salivary concentrations of biomarkers were similar in both periodontitis groups (P > 0.05). Salivary HIF-1α concentrations in gingivitis group were significantly higher than G-AgP and healthy groups (P < 0.05). GCF HIF-1α, VEGF, and TNF-α total amounts were positively correlated with the site-specific clinical periodontal parameters and with each other (P < 0.05). Conclusions: HIF-1α is detectable in GCF and saliva of periodontally diseased and healthy individuals, and the GCF levels of the biomarker can be affected by disease status. Increased GCF HIF-1α, VEGF, and TNF-α levels in both chronic and aggressive form of periodontitis might suggest the role of TNF-α/HIF-1α/VEGF pathway in the pathogenesis of periodontal diseases. © 2018 American Academy of Periodontology

    Effect of non-surgical periodontal treatment on gingival crevicular fluid hypoxia inducible factor-1 alpha, vascular endothelial growth factor and tumor necrosis factor-alpha levels in generalized aggressive periodontitis patients
    (Wiley-Blackwell, 2020) Afacan B.; Keleş Yücel Z.P.; Paşali Ç.; Atmaca İlhan H.; Köse T.; Emingil G.
    Background: Hypoxia-inducible angiogenic pathway involving hypoxia inducible factor-1 alpha (HIF-1α), vascular endothelial growth factor (VEGF) and tumor necrosis factor-alpha (TNF-α) may regulate several biological processes related to inflammation. The present study aimed to assess the effect of non-surgical periodontal treatment on gingival crevicular fluid (GCF) HIF-1α, VEGF, and TNF-α levels in generalized aggressive periodontitis (G-AgP). Methods: Twenty G-AgP patients and 20 periodontally healthy individuals were included. G-AgP patients received scaling and root planning (SRP), per quadrant at a 1-week-interval, performed with ultrasonic and periodontal hand instruments. GCF samples were collected and clinical periodontal parameters including probing depth, clinical attachment level, gingival index and plaque index were recorded at baseline, 1 and 3 months after treatment. Biomarker levels in GCF were analyzed by ELISA. Results: At baseline all clinical parameters and GCF HIF-1α, VEGF, and TNF-α levels were significantly higher in G-AgP patients compared to healthy control (P < 0.05). All clinical parameters improved over the 3-month-period in G-AgP patients (P < 0.05). GCF HIF-1α levels in G-AgP reduced at 1 and 3 months post-treatment, however, this did not reach to statistical significance (P > 0.05). GCF VEGF and TNF-α levels remained unchanged throughout the study period (P > 0.05). Conclusions: Within the limitations of the present study, although HIF-1α seems to possess a potential diagnostic value for G-AgP, it might not be a proper predictor of clinically favorable treatment outcome. SRP plus different adjunctive therapies could provide better information about the prognostic role of hypoxia-inducible angiogenic pathway in G-AgP. © 2020 The Authors.
