What does Ecarin do?

What does Ecarin do?

The ecarin clotting time (ECT) is a meizothrombin generation test that allows for precise quantification of direct thrombin inhibitors. The ECT has demonstrated its usefulness for more than 10 years in biochemical-pharmacological investigations as well as in clinical research and in the clinical routine.

Which of the following anticoagulants is a direct inhibitor of thrombin?

Currently, four parenteral direct inhibitors of thrombin activity are FDA-approved in North America: lepirudin, desirudin, bivalirudin and argatroban. Of the new oral DTIs, dabigatran etexilate is the most studied and promising of these agents.

What anticoagulant therapy is monitored using the Ecarin clotting time ect )?

Ecarin clotting time (ECT) is a laboratory test used to monitor anticoagulation during treatment with hirudin, an anticoagulant medication which was originally isolated from leech saliva. Ecarin, the primary reagent in this assay, is derived from the venom of the saw-scaled viper, Echis carinatus.

What is dilute thrombin time?

It is based on thrombin time, in which a plasma sample is diluted with saline solution and normal pool plasma (NPP) before initi- ation of coagulation with thrombin. Such diluted thrombin time (dTT) yields shorter coagulation times6 and is applicable to different coagulation analysers.

What is a good clotting time?

The average time range for blood to clot is about 10 to 13 seconds. A number higher than that range means it takes blood longer than usual to clot. A number lower than that range means blood clots more quickly than normal.

What is normal clotting time?

The normal clotting time in a person is between 8-15 minutes. By understanding the time taken for blood to clot, it can be determined if the person has haemophilia or von Willibrand’s disease. Bleeding time normal range can still be considered between a one1 minute to eight minutes.

What is thrombin clotting time?

Thrombin clotting time (TCT) is a coagulation assay used to diagnose congenital and acquired fibrinogen deficiency (Adcock et al., Coagulation handbook, Esoterix Coagulation, Austin, TX, 2002), as well as to identify contamination by heparin, prior to performing additional coagulation assays.

Is heparin a direct thrombin inhibitor?

Heparin and warfarin are two indirect thrombin inhibitors2 traditionally used in the management of thrombotic events. One of the major advantages of heparin is its fast action, and for warfarin is its oral availability.

Which anticoagulant binds to thrombin?

Direct thrombin inhibitors (DTIs) bind directly to thrombin and do not require a cofactor such as antithrombin to exert their effect. DTIs can inhibit both soluble thrombin and fibrin-bound thrombin [4].

What is ececarin clotting time?

Ecarin clotting time (ECT) is a laboratory test used to monitor anticoagulation during treatment with hirudin, an anticoagulant medication which was originally isolated from leech saliva.

What is the mechanism of action of ecarin?

Ecarin is isolated from the venom of the saw-scaled viper Echis carinatus and in the assay a known amount of ecarin is added to the plasma. Ecarin activates prothrombin to meizothrombin – this activity is inhibited by lepirudin but is unaffected by heparin. The meizothrombin induces clotting via fibrinogen cleavage to fibrin.

Does ecarin activate prothrombin?

Ecarin can activate both Prothrombin and des-carboxy-Prothrombin [PIVKA = Protein Induced by Vitamin K Absence] – that is the acarboxylated form of Prothrombin that is present in cases of Vitamin K deficiency or in individuals taking a vitamin K antagonist such as Warfarin [although the Prothrombin Time will be prolonged] and in liver disease.

What does ECT stand for in medical terms?

Ecarin clotting time ( ECT) is a laboratory test used to monitor anticoagulation during treatment with hirudin, an anticoagulant medication which was originally isolated from leech saliva. Ecarin, the primary reagent in this assay, is derived from the venom of the saw-scaled viper, Echis carinatus.
