Abstract
OBJECTIVE: Endothelial progenitor cells (EPCs) have recently been considered as a potential novel marker of vascular integrity, atherosclerosis and cardiovascular risk. This study was performed to investigate the main determinants of EPC levels in individuals with prediabetes. DESIGN: Thirty-nine participants with newly diagnosed prediabetes were enrolled. Flow cytometric analysis was used to quantify EPCs (CD34 + CD133 + VEGFR-2+). Traditional risk factors, high-sensitivity C-reactive protein (hs-CRP), homeostasis model assessment of insulin resistance (HOMA-IR) and anthropometric parameters, including ultrasonographic-determined visceral and subcutaneous fat, were recorded. RESULTS: In univariate analysis, EPC levels significantly correlated with waist circumference (p = 0.017), mean arterial pressure (p = 0.009), total cholesterol (p = 0.003), hs-CRP (p = 0.006), HOMA-IR (p = 0.031) and visceral fat (p = 0.040). However, in stepwise multivariate ordinal logistic regression analysis, only visceral fat retained its statistical significance (OR=0.79, 95%Cl:0.64–0.98, p = 0.032). CONCLUSIONS: Visceral fat seems to be the main determinant of EPC levels in individuals with prediabetes and to form a plausible link between mild metabolic abnormalities, cardiovascular risk and vascular homeostasis process.
