Serum and Saliva Sirtuin 6, Lipoxin A4, Caspase8 Levels in Correlation With Periodontal Status in Severe Periodontitis

It has been stated that Sirtuin-6 (SIRT6) play a important role in regulation of inflammation, energy metabolism, homeostasis and apoptosis, and SIRT6 may be assosiciated with many diseases. The aim of this study was to evaluate saliva and serum SIRT6, Lipoxin A4 (LXA4) and Caspase-8 (CASP8) levels in correlation with periodontal clinical status in patients with periodontitis and healthy subjects

Study Overview

• Status: Completed
• Conditions: Periodontitis; Diagnose Disease
• Intervention / Treatment: Other: Saliva and serum sampling

Detailed Description

20 patients with Stage III Grade B periodontitis (P) and 20 periodontally healthy individuals (control;C) were included in this study. Clinical periodontal parameters were measured. Saliva and serum levels of SIRT6, LXA4 and CASP8 were analyzed by enzyme-linked immunosorbent assay.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Saliva and serum collection of patients and samples molecules analysis	Other: Saliva and serum sampling; Saliva were collected to analyze the selected markers as unstimulated samples during the early hours of the day. The saliva was centrifuged and then transferred into Eppendorf tubes. Venous puncture was performed after saliva collection and 10 mL of blood samples were collected by qualified staff (MFD) from each participant. Saliva and serum were then stored at -80 °C until analysis.
Experimental: Salivary and serum SIRT6, LPXA4 and CASP8 observation; Saliva and serum samples obtained for each patient were used for cytokine analysis. Prepared samples were analyzed for Lipoxin A4 (LXA4), Caspase 8 (CASP8) and Sirtuin-6 (SIRT6) using commercial ELISA kits (Elabscience, Houston, Texas, USA and Bioaasay Technology Laboratory (BT-Lab), Shanghai, China, respectively) according to the manufacturer's instructions. The detection limits of ELISA kits were 0.78 - 50ng/ml for LXA4, 0.16 - 10ng/ml for CASP8 and 0.1- 40 ng/ml for SIRT6.	Other: Saliva and serum sampling; Saliva were collected to analyze the selected markers as unstimulated samples during the early hours of the day. The saliva was centrifuged and then transferred into Eppendorf tubes. Venous puncture was performed after saliva collection and 10 mL of blood samples were collected by qualified staff (MFD) from each participant. Saliva and serum were then stored at -80 °C until analysis.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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.	6 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)	6 months
Bleeding on probing	referring to bleeding that is induced by gentle manipulation of the tissue at the depth of the gingival sulcus, or interface between the gingiva and a tooth.	6 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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 Lipoxin A4 (LXA4), Caspase 8 (CASP8) and Sirtuin-6 (SIRT6) using commercial ELISA kits (Elabscience, Houston, Texas, USA and Bioaasay Technology Laboratory (BT-Lab), Shanghai, China, respectively) according to the manufacturer's instructions.	2 months
