* 投稿摘要: Background: Patients with chronic kidney disease (CKD) often exhibit associated endothelial dysfunction and inflam¬mation. Therefore, hemodialysis (HD) is usually associated with increasing thrombotic trend. A disintegrin-like and metallopro¬tease with thrombospondin type 1 repeats 13 (ADAMTS13) is a specific von Willebrand factor (vWF)-cleaving protease can prevent the excessive accumulation of ultralarge VWF multimers and platelet aggregation for microthrombus formation. The aim of this study was to evaluate ADAMTS13 and VWF plasma levels from patients undergoing HD as putative biomarkers of the hypercoagulability state. Methods: Patients undergoing HD (N=42) and 40 healthy subjects (control group) were eligible for this cross-sectional study. We measured the plasma levels of vWF antigen (vWF:Ag) and vWF activity (vWF:RCo) was analyzed in the Sysmex® CS-2000i. ADAMTS13 antigen by ELISA and ADAMTS13 activity was detected with FRETS-vWF73 assay. Results: Both ADAMTS13 activity and antigen levels were significantly decreased in HD patients, as compared to healthy subjects(41±22.8vs103±19.6%;0.67±0.23vs 0.99±0.17;P< 0.00001). The vWF:Ag levels and vWF:RCo were significantly higher than healthy controls(187.86±71.76vs99.55±21.37%;163.94±64.85vs94.37±23.06% ; respectively). The ratio of the vWF: RCo to ADAMTS13 activity was calculated and significantly increased (5.84±4.46 folds) in HD patients. Conclusion: Taken together, our data suggest a potential role of the kidneys function compromised on ADAMTS13 synthesis or metabolism, regardless other known sources of ADAMTS13. The imbalance between ADAMTS13 and vWF levels indicates a prothrombotic state be induced in HD patients.
