Abstract:
OBJECTIVE:To explore whether the high risk factors possibly leading to hypercoagulative status and thrombosis exist in Thalassemia patients of Guangxi region through detecting plasma tissne factor-bearing microparticles (TFMP), procoagulatima activity, coagulation and anticoagulation function, fibrinolytic function, endothelial function and platelet count.
METHODS:The TFMP procoagulation activity was detected by chromogenic saubstract method, the levels of tissue factors (TF), tissue factor pathway inhibitor(TFPI), protein C (PC), protein S (PS), antithrombin Ⅲ(AT-Ⅲ), tissue plasminogen activator (tPA), thrombin-activated fibrinolysis inhibitor (TAFI), soluble E-selectin (sE-sel), intercellular adhesion molecule-1 (ICAM-1) and thrombomodulin (TM) were detected by ELISA in thalassemia group (n=71) and control group (n=20 heathy persons).
RESULTS:Compared with control group, the AT-Ⅲ level decreased in β-thalastemia major group (TM) (P<0.05), the AT-Ⅲ level in TM group independeutly posstiody correlated with plt count (r=0.37, P<0.05); the levels of TF and sICAM in α-thalassenia intermediate group (TA) significantly decteased (P<0.05), the procoagulatim activity of TFMP in β-thalassemia intermediate group (TI) increased sngnificantly (P<0.05)， moreover positively corretated with AT-Ⅲ level (r=0.77, P<0.05). The TF and sICAM-1 levels in normal liver functim group of Thalassemia patients were lower tham those in control group (P<0.01 and P<0.05, respectively), the TFMP activity between normal and abnormal liver function was significantly different (P<0.05), while there were no significant difference in other correspoding indexes beween thalassemia group and control group as well as between each thalassemia groups.
CONCLUSION:The damage of liver function and reduction of anticoagylation substances exist in patients with β-thalassenia major in Guangxi region, the procoagulation activity of plasma TFMP in patients with β-thalassemia intermedia abnormally increases. All the above-mentioned factors may increase the risk of high coagulation status or thrombosis is thalassemia patients, the decrease of TF and SICAM-1 levels in patients with α-thalassemia intermedia may be factor against thrombosis.
