Higher prognostic value of soluble fibrin complexes than D-dimer and fibrin degradation product for disseminated intravascular coagulation in patients with liver cirrhosis

Abstract

Fibrin-related markers may help differentiate disseminated intravascular coagulation (DIC) from liver cirrhosis-associated dysfunctional coagulation. We investigated the significance of three fibrin-related markers [D-dimer, fibrin degradation product (FDP), and soluble fibrin complexes (sFC)] for the assessment of DIC status and prognosis. We classified 235 patients with suspected DIC into two groups according to their condition: the liver cirrhosis group (n = 47) and the no liver cirrhosis group (n = 188). Prothrombin time (PT), and fibrinogen, sFC, D-dimer, antithrombin, and protein C concentrations were measured and DIC scores were calculated using four parameters: platelet count, D-dimer, fibrinogen, and PT. In the liver cirrhosis group, the sFC concentration increased significantly in accordance with DIC score compared with the no liver cirrhosis group, and this increase was more prominent than D-dimer and FDP concentration increases. For the diagnosis of overt DIC in patients with liver cirrhosis, the area under the concentration curve (AUC) was larger for sFC (0.746) than for D-dimer (0.733) and FDP (0.687). Cox analysis also indicated that an elevated sFC concentration is a more significant prognostic factor of DIC than D-dimer or FDP (hazard ratio: 10.78; P = 0.036) in liver cirrhosis group; however, it was not a prognostic factor in the no liver cirrhosis group. sFC is a powerful diagnostic and prognostic marker of DIC in patient with liver cirrhosis. The use of sFC is expected to enhance the diagnosis and prognosis of DIC, particularly in patients with liver cirrhosis.
