Chemerin and Interleukin-6 Levels of Gingival Crevicular Fluid in Obese Individuals Following Periodontal Treatment
A Early Phase 1 study testing Non-surgical periodontal treatment and Gingival crevicular fluid collection in people with Obesity and Periodontitis, run by Umut BALLI.
Trial summary
The objective in this case-control intervention study, therefore, was to explore the effect of nonsurgical periodontal therapy on the GCF levels of chemerin and IL-6 in patients with chronic periodontitis in order to determine the usefulness of chemerin as a diagnostic and prognostic biomarker of periodontal disease.

About this study
Official title: Effects of Non-Surgical Periodontal Treatment on the Gingival Crevicular Fluid Levels of Chemerin in Obese Patients With Chronic Periodontitis
The objective in this case-control intervention study, therefore, was to explore the effect of nonsurgical periodontal therapy on the GCF levels of chemerin and IL-6 in patients with chronic periodontitis in order to determine the usefulness of chemerin as a diagnostic and prognostic biomarker of periodontal disease.
Read the detailed description
All individuals underwent a full-mouth periodontal examination, which included probing pocket depth (PPD), clinical attachment level (CAL), plaque index (PI), gingival index (GI), bleeding on probing (BOP). BMI and WHR were used for assessing obesity. In addition, HbA1c and fasting plasma glucose levels were used for elimination of diabetes mellitus. Based on the periodontal and anthropometric measurements, individuals (n=72) were divided into four groups: the periodontal-healthy group (n=18), chronic periodontitis group (n=18), periodontal-healthy with obesity group (n=18) and chronic periodontitis with obesity group (n=18). Periodontitis patients received nonsurgical periodontal therapy. GCF sampling and clinical periodontal parameters were assessed before and 6 weeks after therapy. Chemerin and IL-6 levels were measured by enzyme-linked immunosorbent assay.

What is being measured
The primary outcome is the main question the study is designed to answer.
Chemerin
The changes in levels of chemerin 6 weeks after periodontal treatment determined by ELISA.
Measured: Baseline and 6 weeks after treatment
Secondary outcomes (6)
Probing pocket depth
The changes in probing pocket depth after periodontal treatment.Probing pocket depth was measured for determining severity of disease and clinic outcome.
Measured: Baseline and 6 weeks after treatment
Clinical attachment level
The changes in clinical attachment level after periodontal treatment. Clinical attachment level was measured for determining severity of disease and clinic outcome.
Measured: Baseline and 6 weeks after treatment
Gingival index
The changes in gingival index after periodontal treatment. Gingival index was recorded for classifying and evaluating (coronally) gingival inflammation. Also, gingival index was also analyzed to detect the relationship between chemerin and interleukin-6.
Measured: Baseline and 6 weeks after treatment
Plaque index
The changes in plaque index after periodontal treatment. Plaque index was recorded for determining and classifying oral hygiene status.
Measured: Baseline and 6 weeks after treatment
Bleeding on probing
The changes in bleeding on probing after periodontal treatment. Bleeding on probing was recorded for classifying and evaluating (apically) gingival inflammation.
Measured: Baseline and 6 weeks after treatment
Interleukin-6
The changes in levels of Interleukin-6 alfa 6 weeks after periodontal treatment determined by ELISA.
Measured: Baseline and 6 weeks after treatment

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Non-surgical periodontal treatment and Gingival crevicular fluid collection in people with Obesity and Periodontitis, run by Umut BALLI.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 22 Jan 2016. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Chemerin (time frame: Baseline and 6 weeks after treatment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Jan 2016.
