[Clinical significance of cross linked fibrin degradation products in thrombotic disorders]

Abstract

We performed a clinical study by measuring the plasma levels of D-dimer, which is derived from the degradation of cross linked fibrin, in some thrombotic disorders using Dimertest EIA kit obtained from AGEN Corp. (Australia). The level of D-dimer in disseminated intravascular coagulation (DIC) were greater than that in thrombotic thrombocytopenic purpura (TTP). These levels of D-dimer in two thrombotic disorders showed a different pathogenesis between them. And also, the levels of D-dimer in some arteriosclerotic disorders, i.e.; aortic aneurysm , cerebral infarction and coronary insufficiency, and in venous thrombosis significantly increased compared with normal subjects. The level of D-dimer measured by Dimertest EIA kit was useful marker for detecting a thrombotic tendency in the low level of D-dimer, in which latex agglutination test for fibrin/fibrinogen degradation products (FDPL test) could not usually detect.
