title: Correlation between cholesterol, soluble P-selectin, and D-dimer in obese children and adolescents.
abstract: Thirty-eight obese children and adolescents were investigated for a possible relation between cholesterol and markers of platelet activation, endothelial cell dysfunction, and activation of the coagulation system. Soluble P-selectin, von Willebrand factor antigen (vWf-Ag), D-dimer, and prothrombin fragment 1 + 2 (F1 + 2) were determined by enzyme-linked immunosorbent assays, and factor VIII coagulant activity (VIIIc) was measured by means of one-stage clotting assay. Cholesterol correlated significantly with log P-selectin (r = 0.43, P = 0.003) and log D-dimer (r = 0.33, P = 0.02). Cholesterol did not correlate with vWf-Ag, factor VIIIc, and F1 + 2. Log P-selectin correlated significantly with log D-dimer (r = 0.42, P = 0.003), which remained significant after adjustment for cholesterol (P = 0.02). Log D-dimer correlated significantly with F1 + 2 (r = 0.38, P = 0.01). Our study demonstrates that, in obese children and adolescents, cholesterol is significantly associated with P-selectin and D-dimer, and suggests an unfavorable intercorrelation between metabolic and hemostatic risk factors for coronary heart disease in childhood obesity.
