C-reactive protein (CRP) is considered a marker of subclinical atherosclerosis. The aim of the study was to assess whether the metabolic syndrome (MS) and parameters involved in its diagnosis might influence serum CRP values.


Cross-sectional study in outpatients of a HTA and Vascular Risk clinic. MS was diagnosed according to National Cholesterol Educational Program ATP-III guidelines, and hs-CRP was analyzed by nephelometry.


A total of 1,969 patients (47% male) were evaluated and distributed into four groups: 1) 1,220 non-diabetics without MS; 2) 384 non-diabetics with MS; 3) 153 diabetics without MS, and 4) 212 diabetics with MS. Patients with MS had higher CRP in both non-diabetic 3.0 (1.7-4.4) mg/l vs. 1.7 (0.9-3.4) mg/l; p=0.001 (MW), and diabetic patients: 2.8 (1.5-4.6) mg/l vs. 2.2 (0.9-4.3) mg/l; p=0.01 (MW). Diabetic patients without MS had CRP values not different to non-diabetic without MS. CRP values increased in relation to the number of parameters included in the MS from 1.7 (2.2) mg/l, in patients without any parameters, to 4.2 (2.8) mg/l in patients who fulfilled five parameters (p=0.001) (KW). In multiple regression analysis abdominal obesity (p=0.001), TG (p=0.001) and glucose (p=0.02) were associated with CRP levels after correcting for other factors. Abdominal obesity (OR: 1.9; 95% CI: 1.5-2.4; p=0.001) and TG (OR: 1.4; 95% CI: 1.1 -1.7; p=0.003), but not glucose were independent factors related to the presence of high levels of CRP (>3 mg/l) in a logistic regression analysis.


Diabetic and non-diabetic patients with MS have high CRP levels. Of the five components of MS, the most closely related to CRP is abdominal obesity.
