High-Sensitivity C-Reactive Protein in Patients with Metabolic Syndrome

High-sensitivity C-reactive protein (CRP) has been shown to predict cardiovascular disease. Metabolic syndrome has been found to play a critical role in the development of cardiovascular disease. The purpose of this report is to assess the relationship between CRP and the metabolic syndrome. A total of 50 patients with metabolic syndrome and 40 healthy persons were included in the study. Plasma concentrations of CRP were measured by means of particle-enhanced immunonephelometry with the Behring nephelometer using N Latex CRP mono reagent. CRP levels were higher in patients with metabolic syndrome than control group (10.6 +/-5.4 mg/L vs 3.5 +/-0.8 mg/L, p<0.001). In partial correlation, plasma CRP positively correlated with body mass index (p<0.001), waist circumference (p<0.001), waist-to-hip ratio (p<0.01), total cholesterol (p<0.001), LDL-cholesterol (p=0.033), triglyceride (p=0.023), and fasting blood glucose (p=0.043) in patients with metabolic syndrome. HDL-cholesterol did not significantly correlate with CRP (p>0.05). In multiple regression analysis, body mass index (p<0.01), waist circumference (p<0.01), and fasting blood glucose (p<0.01) showed independent correlations with plasma CRP. CRP levels were found higher in patients with metabolic syndrome. These results suggest that abdominal obesity is the critical correlates of elevated plasma CRP levels found in patients with metabolic syndrome. These patients carrying high risk for cardiovascular events must be followed closely.
