Expression of apelin among the individuals of chronic periodontitis, with and without type ii diabetes mellitus: A study using enzyme-linked immunosorbent assay

Background: This is the first study showing the co-relationship of apelin among chronic periodontitis (CP) and type 2 diabetes mellitus (T2DM). CP has an anti-inflammatory and anti-glycaemic role in our system. In the future, a localised therapeutic dose of apelin can be used to lower the severity of periodontal disease by reducing the inflammation. The objective of the present study is to investigate the levels of serum apelin from patients with CP, CP + T2DM, and healthy individuals. Materials and Methods: This study included 180 individuals that were equally divided into three groups. Group A consisted of healthy individuals, Group B with CP, and Group C with CP + T2DM. Probing pocket depth (PPD) and serum Apelin (AP) were measured. Serum apelin expression was determined using enzyme-linked immunosorbent assay. Statistical analysis was performed using SPSS software. Results: The highest apelin was in CP + T2DM group (24.0 ± 3.78 ng/dl) followed by CP (15.4 ± 2.01 ng/dl) and healthy individuals (7.6 ± 1.18 ng/dl). There was a significant increase in serum apelin (P ≤ 0.05) in Group C individuals. Similarly, PPD was significantly increased in individuals with CP + T2DM. Conclusion: Expression of significant apelin in patients with CP and T2DM suggests a possible role for these adipokines in inflammation and glucose level regulation. In the future, it may be used as a therapeutic agent in curing periodontitis.
