Utility of clot formation and lysis assay to monitor global coagulation state of patients with severe acute pancreatitis.

BACKGROUND: Systemic inflammation affects hemostasis during severe acute pancreatitis (SAP). A hypercoagulable state occurs more frequently in SAP, which is not fully detected by traditional coagulation testing. AIMS: The aim of this study was to evaluate the contribution of clot formation and lysis (CloFAL) assay to improve monitoring of global coagulation in patients with SAP.
METHODS: Twenty-five patients with SAP who were treated from December 2009 to April 2011 were studied. Plasma was collected at the time of admission, and CloFAL was measured using the CloFAL analyzer. The parameters evaluated include coagulation time (CT), fibrinolysis time (FT), and maximum amplitude (MA), from which the accelerating coagulation extent (ACE, MA/CT), accelerating fibrinolytic extent (AFE, MA/FT), and balance level exponent (BLE, ACE/AFE) were calculated. In addition, laboratory values for the traditional coagulation testing were measured. Values were compared to a control group of 20 healthy subjects.
RESULTS: The MA, FT, ACE, and BLE values of the CloFAL assay were significantly increased in the SAP group compared to the control group (p\0.05 for all measurements). For the traditional coagulation testing, fibrinogen, plasminogen, and D-dimer levels were higher in patients in the SAP group compared to the control group (p\0.05).
CONCLUSIONS: Our findings using the CloFAL analyzer indicate that the hypercoagulable state was due to increased fibrin generation and invariable fibrinolysis in patients with SAP. CloFAL assay is a simple and useful global coagulation assay to monitor hypercoagulable states during SAP.
