Aim: The aim of this paper was to compare serum high sensitivity C-reactive protein (HsCRP) levels and carotid artery intima-media thickness (CIMT) of patients with impaired glucose tolerance (IGT) or impaired fasting glucose (IFG) with that in control subjects.
Methods: Ninety-six subjects with prediabetes, 48 with IFG, of mean age 50.7±11.3 years, and 48 with IGT, of mean age 50.9±12.3 years, were enrolled, along with 44 age-, sex-, and body mass index-matched controls with normal glucose tolerance. Serum HsCRP, lipid profile, insulin levels and the homeostasis model assessment of insulin resistance (HOMA-IR) was evaluated. High-resolution B-mode ultrasonography was performed.
Results: Serum HsCRP levels were significantly elevated in pre-diabetic patients when compared with that of control subjects. Median HsCRP values were 3.1 mg/L in IFG group, 3.47 mg/L in IGT group, and 1.5 mg/L in the controls (P<0.001). CIMT was significantly higher in pre-diabetic groups than that in the control group (IFG: 0.612±0.09; IGT: 0.625±0.1; control: 0.517±0.09, P<0.001). CIMT and HsCRP levels were similar in pre-diabetic groups. CIMT values were positively correlated with HsCRP (r=0.793, P=0.000), age (r=0.435, P=0.000), waist-hip ratio (r=0.170, P=0.044), fasting plasma glucose (r=0.302, P=0.000), HOMA-IR (r=0.173, P=0.041), and low-density lipoprotein cholesterol (r=0.168, P=0.047) levels.
Conclusion: Both IFG and IGT were associated with increased cardiovascular risk as assessed by serum hsCRP levels and CIMT. In contrast to previous studies, risk appears to be the same in the two categories of prediabetes.
