Cerebral venous thrombosis (CVT) rarely recurs, and the factors associated with a recurrence remain unclear. Recently, however, elevated plasma coagulation factor VIII has been considered a factor related to recurrent venous thromboembolism. Here we report a patient who had recurrent CVT associated with significantly elevated levels of factor VIII despite the chronic use of an antiplatelet agen...

Recent progress in the biochemical characterization of coagulation factors VIII and IX has greatly contributed to our understanding of the inheritance of hemophilia and von Willebrand's disease and facilitated the recognition of carriers of these disorders. Factor VIII is a molecular complex which may be quantitated immunologically as factor VIII-related antigen. Within this complex reside the ...

BACKGROUND In patients with severe hemophilia A, standard treatment is regular prophylactic and episodic intravenous infusions of factor VIII. However, these treatments are burdensome, especially for children, and may lead to the formation of anti-factor VIII alloantibodies (factor VIII inhibitors). Emicizumab (ACE910), a humanized bispecific antibody mimicking the cofactor function of factor V...
