Serum chemerin levels are inversely associated with renal function in a general population

Area of Science:

• Nephrology
• Endocrinology
• Metabolic Syndrome Research

Background:

• Chemerin, a protein highly expressed in rodent kidneys, is implicated in metabolic syndrome (MetS) phenotypes and subsequent kidney damage.
• Clinical research on circulating chemerin and human renal function is limited, with no population-based studies addressing MetS phenotype interactions.

Purpose of the Study:

• To investigate the association between serum chemerin and renal function in a general population.
• To explore the potential interaction of MetS-related phenotypes on the chemerin-renal function association.

Main Methods:

• Analysis of data from 4082 participants in the German Study of Health in Pomerania.
• Application of linear and logistic regression models.
• Assessment of outcomes including estimated glomerular filtration rate (eGFR), serum creatinine, cystatin C, and chronic kidney disease.

Main Results:

• A significant inverse association was observed between serum chemerin levels and eGFR.
• Metabolic syndrome components modulated this association, enhancing the inverse relationship.
• Increased chemerin levels (25 ng/mL) were linked to a threefold higher odds of developing chronic kidney disease (OR 2.72).

Conclusions:

• Serum chemerin exhibits a strong inverse association with renal function in the general population.
• MetS phenotypes may mediate this association by contributing to renal damage and influencing chemerin levels or renal clearance.
