High levels of hsCRP are associated with carbohydrate metabolism disorder

摘要

: To determine risk parameters associated with high values of high sensitive C‐reactive protein (hsCRP) in subjects with different glucose fasting levels. : Anthropometric parameters, arterial pressure, glycemia, lipid profile, uric acid, and hsCRP were studied in a population of 513 individuals between 40 and 65 years. : In total, 349 (68.0%) were normoglycemic (NG); 113 (22.0%) had impaired fasting glucose (IFG); and 51 (9.9%) were diabetic subjects. A multivariate linear regression analysis showed that the natural logarithm of hsCRP was associated significantly with glycemia levels ( = 0.009), uric acid ( = 0.001), diastolic blood pressure ( = 0.011), smoking habit ( = 0.021), BMI ( <0.001), and sex ( <0.001). One‐third of the NG subjects had high hsCRP levels. A multiple logistic regression analysis showed that sex and BMI were variables related to high levels of hsCRP in subjects with IFG and NG. In NG subjects, uric acid levels were associated with risk of presenting high hsCRP levels and were higher in women than men. In NG women, ROC curves analysis identified a uric acid level of 3.9 mg/dl as a cut‐off point to predict a high value of hsCRP. Those individuals with uric acid values higher than 3.9 mg/dl and normal glycemia had 3.5‐fold more risk of having hsCRP levels over 3.0 mg/l. : We sustain that high levels of hsCRP are associated with disturbance in carbohydrate metabolism. In addition, we believe that in low cardiovascular risk population, such as NG women, uric acid levels above 3.9 mg/dl might represent a signal of possible pro‐inflammatory state and cardiovascular risk.
