Fibrin-targeted recombinant hirudin inhibits fibrin deposition on experimental clots more efficiently than recombinant hirudin.

Efficiently Than Recombinant Hirudin

Background Although the indirect thrombin inhibitor heparin and the more potent direct inhibitor hirudin are useful in preventing thrombosis, a substantial opportunity remains for improving the thrombus selectivity of thrombin inhibitors. Methods and Results To explore the effect of targeting an antithrombin to the surface of a clot, we covalently linked recombinant hirudin to the Fab' (or IgG)...

Therapeutic levels of recombinant hirudin.

Endotoxin-induced disseminated intravascular coagulation in rabbits: effect of recombinant hirudin on hemostatic parameters, fibrin deposits, and mortality.

We evaluated the effect of r-hirudin on an experimental model of disseminated intravascular coagulation (DIC) in rabbits, through the continuous infusion of 100 microg/kg/hr of Escherichia coli endotoxin for a period of 6 hours. r-Hirudin (0.05, 0.3, and 0.6 mg/kg/hr) as treatment, or saline solution as placebo, were administered simultaneously with endotoxin. Severe DIC in the endotoxin contro...

Recombinant hirudin in clinical practice: focus on lepirudin.

Clinical applications for recombinant hirudins have been investigated for the past 10 years. The first indication for which a hirudin-lepirudin-has been approved is treatment of heparin-induced thrombocytopenia (HIT). Also, the recently completed trials for use of lepirudin in unstable angina indicate a potentially new indication. This review describes pharmacology and clinical applications of ...

Anticoagulation in extracorporeal circulation using recombinant hirudin: a case report.

Heparin-induced thrombocytopenia (HIT) is a severe complication following the application of heparin; antibodies against complexes of heparin and PDF4 initiate activation of platelets. This may lead to massive thrombembolism, which is associated with a slight and transient drop of platelets in HIT I or a drop below 50% after approximately 5 days in HIT II. Further administration of heparin has ...
