Abstract:
Objective Todeterminethecorrelationbetweenthrombomodulinand atherosclerosis in chronic kidney diseases (CKD) patients.Methods A total of 96 CKD patients in our hospital were enrolled in the study, including 32 maintenance hemodialysis(MHD) patients and 64 non-hemodialysis CKD patients with stage 2 to 5(non-HD) and 30 age- and gendermatched healthy volunteers were used as control.Intima-media thickness(IMT) and atherosclerotic plaquesof theextracranialcommoncarotidarteryweredetectedbyhigh-resolutionB-mode ultrasonography. Bloodlevelof thrombomodulinwasmeasuredusingELISA,andcreatinine,triglycerides, cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol were measured routinely as well.Correlation analysis of thrombomodulin with other parameters was performed.Results The thrombomodulin level was significantly higher in CKD patients as compared to healthy controls[(12.15±3.04) mg/L vs(3.12±0.23) mg/L, P＜0.05], and also significantly higher in MHD patients as compared to non-HD patients [(16.89±3.35) mg/L vs (9.78±2.49) mg/L, P＜0.05].The atherosclerotic plaques incidence and IMT value of carotid artery increased significantly in CKD patients compared with healthy volunteers.Thrombomodulin was positively correlated with IMT in CKD patients(r=0.335, P＜0.01).Multiple stepwise regression analysis showed that thrombomodulin, Tm (OR=1.13, 95％CI 1.010-1.121), SBP (OR=1.09, 95％GI 1.009-1.114), CRP(OR=1.22, 95％CI 1.216-2.007), and Scr were independent risk factors of IMT.ConclusionThrombomodulin is correlated with carotid atherosclerosis in CKD patients and may be used as a marker to evaluate the endothelial damage.
