Patients with coagulation factor(s) deficiency who use coagulation therapy are susceptible to forming inhibitors against coagulation factor(s). In this survey we detected factor V and VIII inhibitor in ten patients with combined deficiency of factors V and VIII from north east of Iran (Khorassan province). It was revealed in our survey that eight patients had both factor V and factor VIII i...

Mice with hemophilia B have been engineered using gene targeting techniques. These animals exhibit severe factor IX deficiency and a clinical phenotype that mirrors the human disease. We have bred the founder animals onto two different strains of mice, C57B1/6 and CD-1, and have sought to determine whether adenoviral vectors expressing human factor IX could correct the bleeding diathesis of mic...

A radioimmunoassay for alloantibodies (inhibitors) and heteroantibodies to human factor IX has been developed using radioiodinated human factor IX and formalin-fixed, heat-killed Staphylococcus aureus cells (Staph A). Staph A was used as a solid-phase adsorbent for immune complexes. The assay is specific, shows excellent correlation with factor IX coagulant neutralization assays in detecting al...

Replacement therapy for hemophilia B (factor IX deficiency) using prothrombin complex concentrate (PCC) has been associated with serious complications of thromboembolic events and transmission of viral infections. Monoclonal antibody-purified factor IX (Mononine) provides a highly purified factor IX concentrate, while eliminating other vitamin K-dependent factors (11, VII, and X). Mononine was ...

BACKGROUND AND PURPOSE Milk fat globule-EGF factor-8 (MFGE8) has been reported to be neuroprotective in ischemic stroke. However, the effects of MFGE8 in early brain injury after subarachnoid hemorrhage (SAH) have not been investigated. We investigated the role of MFGE8 in early brain injury and the potential mechanisms in antioxidation after SAH. METHODS Two dosages (1 μg and 3.3 μg) of reco...

Immune tolerance induction (ITI) in patients with haemophilia B and inhibitors may be complicated by anaphylactic reactions and nephrotic syndrome with lower success rates than in haemophilia A (25% vs. 50-90%). According to case reports, immunosuppressive therapy in addition to high doses of factor IX (FIX) appears to be promising. We report an 18-year-old patient with severe haemophilia B and...
