Inflammatory ResponseNCT05474820
Saliva Irisin Level is Higher and Related With Interleukin 6 in Generalized Periodontitis
A study testing Samples collection and ELISA analyses and Evaluating periodontal paramètres in people with Inflammatory Response and Periodontitis, run by Istanbul Medipol University Hospital at 1 site in Turkey (Türkiye).
Trial summary
Irisin is novel adipomyokine known as a mediator of physical activity that produced mainly by skeletal muscle and adipose tissues. It is cleaved from the fibronectin type III domain-containing protein 5 (FDNC5), which is, in turn, induced by peroxisome proliferator-activated receptor-ɣ co-activator 1-α (PGC-1α).

About this study
Irisin is novel adipomyokine known as a mediator of physical activity that produced mainly by skeletal muscle and adipose tissues. It is cleaved from the fibronectin type III domain-containing protein 5 (FDNC5), which is, in turn, induced by peroxisome proliferator-activated receptor-ɣ co-activator 1-α (PGC-1α). Several studies reported that irisin is related with pathogenesis of many diseases which are known to be associated with periodontal disease such as obesity, diabetes mellitus, rheumatoid arthritis, cardiovascular disease, nonalcoholic fatty liver disease and metabolic bone diseases. There are several studies those have reported that increased IL-6 levels are associated with progression and severity of periodontitis . Recently, it has been shown that irisin is expressed in human periodontal ligament cells (hPDL), dental pulp stem cells and osteoblasts. Also, a few studies revealed that irisin promotes growth, migration and matrix formation in hPDL cells and cementoblast differentiation. To the best our knowledge, there 's one study has been reported that the higher levels of irisin in saliva in patient with chronic periodontitis
Read the detailed description
Twenty systemically healthy subjects with healthy periodontium and 20 patients with stage III grade B generalized periodontitis were enrolled for this cross-sectional study. The study was performed in accordance with the Helsinki Declaration of 1975, as revised in 2013. Before starting, the informed consent was obtained from all participants which was approved by the human subject's ethics board of Istanbul Medipol University's Faculty of Dentistry for use and access of human subjects in research.For all study subjects, the exclusion criteria were (1) use of contraceptive drugs; (2) use of antibiotics, anti-inflammatory drugs, or immunosuppressants in the last 3 months before the study; (3) alcohol consumption; (4) pregnancy or breastfeeding; (5) taking drugs that could cause side effects such as gingival hypertrophy or hyperplasia; and (6) any periodontal treatments in the 3 months prior to enrollment. All participants were systemically healthy and non-smokers (never smokers).The clinical periodontal parameters (plaque index (PI), probing pocket depth (PD), gingival recession (GR), clinical attachment loss (CAL), and bleeding on probing (BOP)) were recorded on periodontal charts in each patient .For the analysis of irisin and IL-6 specific ELISA Kits (Elabscience, Houston, Texas, USA) were used to determine the molecules in both serum and saliva samples in accordance with the manufacturer's instructions. The minimum detectable doses of irisin and IL-6 for saliva with these assay kits were 1,28 and 13,22 pg/ml, respectively. For serum, minimum detectable irisin dose was 175,43 whereas IL-6 was 0,06 pg/ml. All samples were run in duplicate, and values have been averaged.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Samples collection and ELISA analysesOther
The serum and unstimulated saliva samples were taken from all patients between 8:00 and 10:00 in the morning. Saliva samples were centrifuged at 10,000 rpm (10 min) whereas venous blood samples were centrifuged at 4000 rpm for 10 min.
For the analysis of irisin and IL-6 specific ELISA Kits (Elabscience, Houston, Texas, USA) were used to determine the molecules in both serum and saliva samples in accordance with the manufacturer's instructions. All samples were run in duplicate, and values have been averaged.
Evaluating periodontal paramètresDiagnostic test
The clinical periodontal parameters (plaque index (PI), probing pocket depth (PD), gingival recession (GR), clinical attachment loss (CAL), and bleeding on probing (BOP)) were recorded on periodontal charts in each patient
| Study group | Role | What they receive |
|---|---|---|
| Saliva and serum collection of patients and samples molecules analysis | Other | After periodontal examination, samples were collected from all patients via informing them about procedures. Then all samples were stored at -80 C unto analyses. Receives: Other: Samples collection and ELISA analyses; Diagnostic Test: Evaluating periodontal paramètres |
| Periodontal examination | Other | All periodontal indices were measured in six sites in each tooth present in the arch by one calibrated periodontist Receives: Other: Samples collection and ELISA analyses; Diagnostic Test: Evaluating periodontal paramètres |
What is being measured
The primary outcome is the main question the study is designed to answer.
Pocket probing depth
Measurement of the depth of a sulcus or periodontal pocket determined by measuring distance from a gingival margin to the base of the sulcus or pocket with a calibrated periodontal probe.
Measured: 3 months
Clinical attachment level
Clinical attachment level (or loss, CAL) is a more accurate indicator of the periodontal support around a tooth than probing depth alone. CAL is measured from a fixed point on the tooth that does not change, the CEJ.
To calculate CAL, two measurements are needed: distance from the gingival margin to the CEJ and probing depth.
In recession: probing depth (+) gingival margin to the CEJ (add). In tissue overgrowth: probing depth (-) gingival margin to the CEJ (subtract)
Measured: 3 months
Secondary outcomes (1)
Saliva and serum samples processing and analyses
Saliva and serum samples obtained for each patient were used for cytokine analysis. Prepared samples were analyzed for Irisin and IL-6 via ELISA kits.
Measured: 1 month
