Chemerin and interleukin-6 levels in obese individuals following periodontal treatment.
OBJECTIVE
To investigate changes in the levels of gingival crevicular fluid (GCF) chemerin and interleukin-6 (IL-6) in both obese/non-obese individuals with periodontitis following non-surgical periodontal therapy.


METHODS
Individuals (n = 80) were split into four groupings according to periodontal/anthropometric parameters: (i) periodontal healthy without obesity; (ii) chronic periodontitis (CP) without obesity; (iii) periodontal healthy with obesity; and (iv) CP with obesity. Individuals with periodontitis were treated with non-surgical periodontal therapy. Both GCF sampling procedures and clinical periodontal measures were performed prior to treatment and 6 weeks thereafter. Enzyme-linked immunosorbent assay was utilized to measure both chemerin and IL-6 levels.


RESULTS
Greater values for chemerin and IL-6 were observed in obese individuals compared to their non-obese controls and in individuals with CP compared to their periodontal healthy controls (P < 0.008), which decreased following therapy (P < 0.05). A positive correlation was found between chemerin and IL-6 in obese groups (P < 0.05). A comprehensive overview of all groups showed a statistically significant positive correlation among chemerin, along with IL-6, waist-to-hip ratio, body mass index, and clinical attachment levels (P < 0.05).


CONCLUSIONS
It could be concluded that chemerin levels may act as both diagnostic and prognostic indicators. Chemerin may also play an integral part in the pathologic mechanisms that relate adipokines to both periodontal disease and obesity.
