The direct thrombin inhibitor lepirudin is mainly applied in heparin-induced thrombocytopenia. We report here the case of a 37-year-old kurdish woman in whom Behcets disease was diagnosed in 1998 when she presented with a Budd Chiari syndrome (BCS) complicated by pulmonary embolism. Recurrent venous thromboembolism (VTE) occurred despite anticoagulant therapy with UFH, LMWH or phenprocoumon and various immunosuppressive therapy regimens. In 2001, when BCS recurred ultimately i.v. lepirudin was administered. When the patient improved and remained clinically stable lepirudin was applied subcutaneously. During long-term treatment with twice-daily 50 mg no further VTE was observed over the following years. Additionally, no bleeding complications occurred. In May 2005 anticoagulant therapy was switched to phenprocoumon. BCS reoccurred when INR values were suboptimal in February 2007, and lepirudin treatment was immediately restarted. After admission the patient received 50 mg b.i.d. lepirudin s.c. with plasma levels in the therapeutic range (0.5-1.0 mg / l). Over the following months, lepirudin levels repeatedly exceeded the upper limit of this range and the dosage was stepwise reduced. Finally, 20 mg b.i.d. were sufficient to obtain therapeutic levels. Renal function was normal, but lepirudin antibodies were present in high titer, as assessed by ELISA. We suppose that these antibodies reduce renal filtration of lepirudin thus leading to increased plasma levels. This case is an example for successful long-term therapeutic-dose anticoagulation with s.c. lepirudin in a patient with Behcets disease and recurrent VTE despite therapeutic anticoagulant therapy with LMWH or vitamin K antagonists. However, frequent measurement of lepirudin plasma levels is needed. If stepwise dose lowering is required over time, the presence of lepirudin antibodies should be considered.
