Abstract：
:Patients with essential hypertension (EH) and hyperhomocysteinemia (HHCY) suffer from more increased thrombotic events than those in EH alone. However, the underlying mechanisms for this effect are not well understood. This study hypothesized that neutrophil extracellular trap (NET) releasing may be triggered by HHCY in patients in EH, thereby predisposing them to a more hypercoagulable state. Using a modified-capture enzyme-linked immunosorbent assay (ELISA) method, we observed that cell-free DNA (CF-DNA) and myeloperoxidase DNA (MPO-DNA) in patients With EH and HHCY were significantly higher. The NET formation was also positively correlated with homocysteine levels, neutrophil-lymphocyte ratio (NLR), and hypercoagulable markers (thrombin-antithrombin complex, D-dimers). Furthermore, neutrophils from patients in EH with HHCY were found to be predisposed to amplified NET release when compared to patients in EH without HHCY or CTR. Coagulation function assays showed that NETs in patients With EH and HHCY resulted in a significantly increased ability to generate thrombin and fibrin than in those in EH without HHCY or CTR. These procoagulant effects of NETs in patients With EH and HHCY were markedly inhibited (approximately 70%) by the cleavage of NETs with DNase I. Isolated NETs from patients With EH and HHCY neutrophils also exerted a strong cytotoxic effect on endothelial cells (ECs), converted them to apoptosis. This study revealed a previously unrecognized association between the hypercoagulable state and neutrophils in patients With EH and HHCY. Therefore, blocking NETs may represent a new therapeutic objective for preventing thrombosis in these patients.
