Serum chemerin is associated with inflammatory and metabolic parameters-results of a population-based study

OBJECTIVE: This study aimed to confirm existing assumptions about the associations of circulating chemerin with inflammatory and metabolic parameters in a large population-based study.

METHODS: Data of 3,986 subjects from the Study of Health in Pomerania were analyzed. Residual method was used to investigate the different associations of visceral (VAT) and subcutaneous adipose tissue (SAT) with serum chemerin levels. Multivariable regression models were applied to examine the association of chemerin with high-sensitivity C-reactive protein, fibrinogen, glucose, glycated hemoglobin, lipid profile, blood pressure, diabetes, dyslipidemia, and hypertension.

RESULTS: Positive associations with chemerin were observed for VAT and SAT with a stronger relation found for VAT. After adjustment for waist circumference, increased chemerin levels were related to higher inflammatory cytokines and glycated hemoglobin and an unfavorable lipid profile. Logistic regression revealed positive associations of chemerin with dyslipidemia [highest vs. lowest quartile: odds ratio (OR) 1.56 (95% confidence interval (CI) 1.25-1.94)] and hypertension [OR 1.31 (95% CI 1.03-1.68)].

CONCLUSIONS: Chemerin levels are significantly linked to inflammation and metabolic syndrome. The majority of the detected associations persisted even after adjustment for waist circumference, suggesting that the relation of chemerin with the analyzed traits cannot be solely explained by an accumulation of adipose tissue.
