چکیده
OBJECTIVES We tested whether Behçet's disease (BD) is characterized by alterations of circulating endothelial progenitor cells (EPCs),which are involved in vascular homeostasis and repair. METHODS We enrolled 30 BD patients and 27 matched healthy controls. EPCs were defined and measured by flow cytometry according to the expression of CD34, CD133 and KDR. RESULTS We show that BD patients had significantly lower levels of CD34+KDR+ and CD34+CD133+KDR+ EPCs than controls. We found significant negative correlations between EPC phenotypes and BD duration, while there were positive correlations between CD34+KDR+ EPCs and both BD activity scores and C-reactive protein. The lower EPC levels with increasing disease duration was shown in univariate analysis and in multivariable analysis adjusted for possible confounders. CONCLUSION This is the first report that BD is associated with progressive EPC decline. Reduction of EPCs may represent a mechanism of induction and/or progression of vascular injury in these patients.

Abstract Background and Objectives Dysfunction of endothelial cells is associated with the development of atherosclerosis and cardiovascular disease. Adult endothelial progenitor cells are derived from hematopoietic stem cells capable of forming new blood vessels through a process of angiogenesis. This study was to investigate the effect of resistance training on HIF-1α gene expression and rec...

Introduction: Psoriasis is an inflammatory skin disease in which abnormal individual immune reactivity plays an important role. Eselectin and P-selectin are adhesion molecules expressed on vascular endothelial cells in several inflammatory skin diseases, including psoriasis. The aim of the present study was to describe selected immunological changes, concerning adhesion molecules status (sEsele...

Background: Psoriasis is a chronic disease with multiple biochemical and vascular abnormalities. Several studies have evaluated circulating levels of vascular endothelial growth factor (VEGF) in psoriasis, but none of them evaluated it after reaching a PASI-75 response, as a practical treatment goal. The aim of this study was to evaluate serum levels of VEGF in moderate to severe psoriatic pati...
