Anticoagulant efficacy of PEG-Hirudin in patients on maintenance hemodialysis.

Background: Heparins are currently the anticoagulants of choice in long-term hemodialysis (HD). Because of their shortcomings, including the increasing incidence of heparin-induced thrombocytopenia (HIT II), alternative anticoagulation is necessary. The study objectives were to provide safe and effective HD by investigating an appropriate PEG (polyethylene glycol)-Hirudin dosage regimen in patients on HD, as well as to compare the safety, tolerability, and efficacy of PEG-Hirudin with that of unfractionated heparin (UFH).
