Background: The vascular endothelium is markedly disrupted in sickle cell disease (SCD) and is the converging cascade of the complex pathophysiologic processes linked to sickle cell vasculopathy. Circulating endothelial activation and/or apoptotic markers may reflect this endothelial activation/damage that contributes to the pathophysiology of the SCD vascular complications. Methods: Plasmatic levels of circulating endothelial cells (CECs), E‐selectin, progenitor's endothelial cells (EPCs), and circulating extracellular vesicles (EVs) were evaluated in 50 SCD patients, 16 with vasculopathy. The association between these markers and the occurrence of disease‐related microvascular injuries of the eye (retinopathy), kidney (nephropathy), and skin (chronic active ulcers) was explored. Results: Among the endothelial activation markers studied, only higher plasma levels of E‐selectin were found in SCD patients with vasculopathy (p =.015). Increased E‐selectin levels were associated with retinopathy (p <.001) but not with nephropathy or leg ulcers. All patients, at steady state, with or without vasculopathy, did not display a high count of CEC and EPC, markers of endothelial injury and repair. We did not show any significant differences in EVs levels between vasculopathy and not vasculopathy SCD patients. Conclusions: Further studies will be required to determine whether the E‐selectin could be used as an early biomarker of retinopathy sickle cell development. [ABSTRACT FROM AUTHOR] |
