Background and aim Adipokines and hepatokines are proteins secreted by adipose tissue and the liver. To date, the levels of adipokines and hepatokines in cholelithiasis have only been evaluated in studies in adult patients. The purpose of our research was to assess the levels of circulating adipokines: chemerin, vaspin, progranulin, retinol‐binding protein 4 (RBP‐4) and hepatokine: fibroblast growth factor 21 (FGF‐21) and to compare their concentrations in paediatric patients with and without cholelithiasis. Methods The prospective study included 54 children and adolescents diagnosed with gallstones and 26 controls. Fasting serum levels of adipokines and hepatokine were determined by enzyme‐linked immunosorbent assays. Results The serum levels of chemerin, FGF‐21 and RBP‐4 were significantly higher in children and adolescents with gallstones compared to the control group. Elevated levels of triglycerides, RBP‐4, and a homeostatic model for assessing insulin resistance (HOMA‐IR) were observed in overweight or obese patients compared to patients with normal weight and cholelithiasis. Chemerin concentrations were increased in the normal‐weight children and adolescents with cholelithiasis compared to the control group. Children and adolescents with gallstones and abnormal weight had significantly higher levels of chemerin, FGF‐21 and RBP‐4 than healthy controls. Conclusion Elevated serum chemerin levels were significantly higher in non‐obese patients with cholelithiasis than in non‐obese controls, suggesting a potential role of chemerin in the development of cholelithiasis in children and adolescents.
