Abstract/OtherAbstract:
Background: It has been well established that hemostatic potential in patients with chronic liver disease is in a rebalanced status due to a concomitant decrease in pro- and antihemostatic drivers. The hemostatic changes in patients with acute liver injury/failure (ALI/ALF) are similar, but not identical to the changes in patients with chronic liver disease and have not been studied in great detail. Objective: To assess thrombin generation and fibrinolytic potential in patients with ALI/ALF. Methods: We performed thrombin generation tests and clot lysis assays in platelet-poor plasma from 50 patients with ALI/ALF. Results were compared with values obtained in plasma from 40 healthy volunteers. Results and conclusion: The thrombin generation capacity of plasma from patients with ALI/ALF sampled on the day of admission to the hospital was indistinguishable from that of healthy controls, provided thrombomodulin was added to the test mixture. Fibrinolytic capacity was profoundly impaired in patients with ALI/ALF on admission (no lysis in 73.5% of patients compared to 2.5% of the healthy controls), which was associated with decreased levels of the plasminogen and increased levels of plasminogen activator inhibitor type 1. The intact thrombin generating capacity and the hypofibrinolytic status persisted during the first week of admission. Patients with ALI/ALF have a normal thrombin generating capacity and a decreased capacity to remove fibrin clots. These results contrast with routine laboratory tests such as the PT/INR, which are per definition prolonged in patients with ALI/ALF and suggest a bleeding tendency. © 2012 International Society on Thrombosis and Haemostasis.
