Association of Progranulin and High Sensitivity CRP Concentrations in Gingival Crevicular Fluid and Serum in Chronic Periodontitis Subjects with and without Obesity

Abstract

Background: Obesity is considered as a strong risk factor of inflammatory periodontal tissue destruction. The purpose of this study is to determine presence of progranulin (PGRN) and high sensitivity C reactive protein (hs CRP) levels in serum and gingival crevicular fluid (GCF) in obese subjects with chronic periodontitis and to find an association, if any.

Material and methods: 40 subjects (20 males and 20 females) were selected based on their clinical parameters into four groups (10 subjects in each group): group 1 (healthy non obese), group 2 (healthy obese), group 3 (non obese with chronic periodontitis) and group 4 (obese with chronic periodontitis). Serum and GCF PGRN levels were estimated by enzyme linked immunosorbant assay (ELISA) and hs CRP levels were estimated by immunoturbidimetry method.

Results: The mean PGRN and hs CRP concentration both in serum and GCF were highest for group 4 followed by group 3, group 2 and least in Group 1.

Conclusion: PGRN and hs CRP may be novel biomarkers of the chronic inflammatory response in obesity and chronic periodontitis.
