Popis: Background The aim of the present study was to evaluate endothelial status by measuring the concentration of novel markers of endothelial dysfunction (ED): a number of circulating endothelial cells (CECs), circulating endothelial progenitor cells (CEPCs) and their ratio (CEPCs/CECs) as well as a traditional parameter - soluble thrombomodulin (sTM) in patients with resistant (RH) and mild hypertension (MH). Materials and methods Thirty patients with MH and thirty subjects with RH were involved in the study. The control group included thirty-three age and sex-matched normotensive volunteers. We used multicolor flow cytometry for CECs and CEPCs analysis and the commercial human sTM ELISA kit to measure plasma sTM concentration. Results An elevated CECs number and a decreased CEPCs/CECs ratio was found in MH as well as in RH patients in comparison with normotensive volunteers. CECs correlated positively with an increased triglycerides in MH patients and an elevated LDL-cholesterol and hsCRP in RH group. Positive correlation between CEPCs and LDL-cholesterol level was observed in both types of hypertension. Conclusions The results of the present study suggest that an endothelial alteration accompanies hypertension. The number of CECs reflecting the extent of endothelial damage does not appear to be related to the severity of disease. The drastically decreased ratio between CEPCs and CECs observed in both groups of patients suggests an inadequate process of endothelial regeneration. Among analyzed factors inflammation and lipid abnormalities may have significant contribution in endothelial pathology in hypertension.
