Circulating chemerin level may be associated with early vascular pathology in obese children without overt arterial hypertension - preliminary results.

Background Elevated chemerin level is observed in patients with arterial hypertension. The aim of the study was to determine the relationship between chemerin level, and parameters of blood pressure and arterial stiffness in children and adolescents with obesity but without arterial hypertension. Methods In 23 children with obesity (13 girls, mean age 9.3, SD 1.9, mean BMI SDS 3.9, SD 1.7) 24 h ABPM (Spacelabs 90,217, USA), common carotids and abdominal aorta intima media thickness measurements (Voluson 730, GE Medical System 8.5 and 3.5 MHz probes), body composition analysis (Tanita BC 418 S MA, Tokyo, Japan) were performed. Glucose, triglycerides, total, LDL and HDL cholesterol, liver enzymes, uric acid, creatinine, sodium, insulin and chemerin levels were assessed in blood sample taken after a 12-h fasting period. Results There was a significant correlation of circulating chemerin level with systolic blood pressure load in ABPM (r=0.5, p<0.05). Conclusion Elevated chemerin level may be associated with increased systolic blood pressure in obese children.
