Relationship Between Serum Endocan Levels and Other Predictors of Endothelial Dysfunction in Obese Women

Endocan, or endothelial cell-specific molecule-1 (ESM-1), is a potential inflammatory marker implicated in endothelial dysfunction. The purpose of this study was to determine the correlation between serum endocan levels and the presence and severity of endothelial dysfunction, and the relationships with serum intracellular adhesion molecule-1 (ICAM-1), adiponectin (a marker of inflammation), high sensitivity C-reactive protein (hsCRP) levels, and carotid intima-media thickness (cIMT) in obese subjects. Serum endocan, ICAM-1, adiponectin, hsCRP levels, and cIMT were evaluated in 76 obese women (BMI > 30 kg/m(2)) and 53 controls (BMI < 25 kg/m(2)). ICAM-1 (P = .01), hs-CRP (p < 0.001), and cIMT (p < .001) were significantly higher, while adiponectin (P = .006) was significantly lower, in obese women compared with the controls. Serum endocan levels were similar between the obese (470.5 +/- 171.3 pg/mL) and controls (471.9 +/- 146.3 pg/mL) (P = .732). There was no correlation between serum endocan values and the endothelial dysfunction markers, hsCRP (r = -.021), ICAM-1 (r = -.054), adiponectin (r = .113), or cIMT (r = -.060) in obesity. Endocan is not a suitable marker of endothelial dysfunction in the context of obesity. More research is required to evaluate the role of endocan in the regulation of inflammatory processes in obesity.

Automated summary

The study aimed to investigate the correlation between serum Endocan levels and the presence and severity of endothelial dysfunction, as well as its relationships with other markers. The results showed no correlation between serum Endocan values and endothelial dysfunction markers in obese women.
