Prophylaxis in congenital hemophilia with inhibitors: the role of recombinant activated factor VII

Abstract

The development of inhibitors against therapeutically administered factors VIII or IX is actually the most challenging complication of hemophilia patients with inhibitors. The introduction of bypassing agents (i.e., activated prothrombin complex concentrates and recombinant activated factor VII [rFVIIa]) has dramatically improved the management of bleeding episodes in such patients. Over the last decade, there have been increasing reports on the ability of bypassing agents to prevent surgical, joint, or other bleeds in inhibitor patients. The published data on the use of rFVIIa as a prophylactic treatment in hemophilia patients with inhibitors are reviewed in this article.
