GCF adrenomedullin levels in healthy and periodontitis patients with or without type 2-diabetes mellitus: Clinicobiochemical study

Background: The literature suggests that periodontal disease and diabetes mellitus share a two-way relationship. The aim of this study was to evaluate and compare the levels of adrenomedullin (ADM) in gingival crevicular fluid (GCF) of periodontally healthy and periodontitis patients with or without type 2 diabetes with different glycemic controls. Methods: Ninety patients were included in the study and were divided into five groups based on CPI scores and ADA classification of diabetes. Probing pocket depth (PPD) and clinical attachment level (CAL) were measured in all the subjects. GCF was collected from all the participants using micropipettes. ADM levels were measured in GCF samples by enzyme-linked immunosorbent assay. Results: The results showed higher levels of ADM in patients with periodontitis as compared to healthy group. Significant correlation was present between PPD and CAL and ADM levels in all periodontitis patients with or without type 2 diabetes. Conclusion: Increase in GCF levels of ADM from periodontal health to disease and in periodontitis patients with type 2 diabetes with the worsening of glycemic control underlines the possible role of ADM in mounting a protective response to worsening disease state.
