Fibrin-related markers (FRM) such as fibrin monomer (FM) and D-dimer (DD) are considered useful biological markers for the diagnosis of disseminated intravascular coagulation (DIC). However, no studies on the diagnostic performance of different FRMs have been published in Korea. The aim of this study was to evaluate the diagnostic performance of FM for DIC in comparison with DD.
The reference limit of FM was determined based on plasma sample data obtained from 210 control individuals. To evaluate diagnostic performance, FM data from the plasma samples of 139 patients with DIC-associated diseases were obtained for DIC scoring. FM was measured by immunoturbidimetry using STA-LIATEST FM (Diagnostica Stago, France). Patients were classified according to the DIC score as non-DIC, non-overt DIC, or overt DIC. ROC curve analyses were performed.
The reference limit in the control individuals was determined to be 7.80 µg/mL. Patients with DIC-associated diseases were categorized as non-DIC (N=43), non-overt DIC (N=80), and overt DIC (N=16). ROC curve analyses showed that the diagnostic performance of FM was comparable to DD in both non-overt DIC and overt DIC (P=0.596 and 0.553, respectively). In addition, FM had higher sensitivity, specificity, positive predictive value, and negative predictive value than DD for differentiating overt DIC from non-DIC.
This study demonstrated that the diagnostic performance of FM for DIC was comparable to DD. FM might be more sensitive and more specific than DD in the diagnosis of overt DIC, but not non-overt DIC.

    ABSTRACT: Deep venous thrombosis (DVT), which is associated with pulmonary embolism, is a fatal disease because of its high morbidity and mortality in outpatients and inpatients, especially in hospitalized patients. At the same time, lack of subjective clinical symptoms and objective clinical signs makes the diagnosis complicated. Historically, the primarily imaging modalities, including duplex ultrasound, helical CT scans, and venography, establish the diagnosis of DVT. Currently, both imaging modalities and serology are utilized. These plasma molecules are regarded as the biomarkers of DVT including D-dimer, P-selectin, Factor VIII, thrombin generation, inflammatory cytokines, microparticles, fibrin monomer, leukocyte count and so on. This brief review is used to analyze the contribution of the biomarkers to diagnosis and guidance of therapy for DVT.
