Canine Autoimmune Hemolytic Anemia (AIHA & IMHA) - Unfractionated heparin therapy

Interesting study. Unfractionated heparin therapy has been shown to be a cost effective way to treat acute thromboembolism in humans. Big plus for veterinary care. This might be the next big thing in emergency care for Canine AIHA.

Unfractionated heparin therapy was initiated at a standard dosage of 300 IU/kg subcutaneously q 6 hours to 18 dogs with immune-mediated hemolytic anemia. Heparin's prolongation of activated partial thromboplastin time and change in factor Xa inhibition (anti-Xa activity) were serially monitored during the first 40 hours of therapy. During the initial 40 hours, only eight of 18 dogs had attained anti-Xa activities of > or =0.35 U/mL. No dogs had clinical signs of hemorrhage. Fifteen dogs survived to discharge; 11 dogs were alive at 1 year, and thrombosis was identified in three of six nonsurvivors that were necropsied.
