High levels of endothelial progenitor cells and circulating endothelial cells in patients with Beh？et's disease and their relationship to disease activity

Beh？et's disease is a multisystemic vasculitis, associated with vascular endothelial dysfunction. Currently, the prognosis is unpredictable, because there is still no valid laboratory marker indicating the disease activity in Beh？et's disease. Endothelial progenitor cells and circulating endothelial cells are newly introduced hematological markers which are presumed to take part in the pathogenesis of vasculitis
