Severe anaphylactic reaction after repeated intermittent exposure to lepirudin.

Lepirudin, a recombinant DNA derivative of hirudin, is used to prevent thromboembolic complications caused by heparin-induced thrombocytopenia type II. Anaphylactic and anaphylactoid reactions have been reported with its use in patients both with and without known previous exposure to lepirudin. We describe the case of a 57-year-old woman who received five uneventful courses of lepirudin therapy before having a severe anaphylactic reaction during administration of the intravenous bolus dose that began her sixth course.

Clinical manifestation of atherosclerotic peripheral arterial disease and the role of cilostazol in treatment of intermittent claudication.

Intermittent claudication (IC) is the symptomatic expression of peripheral arterial disease (PAD), which itself is a manifestation of systemic atherosclerosis. Like other forms of atherosclerosis, PAD is associated with elevated rates of cardiovascular and cerebrovascular morbidity and mortality. Until recently, therapeutic options for the treatment of the symptoms of IC have been limited, and the efficacy of available treatment has been questioned.
