Refractory Epistaxis due to Severe Factor V Deficiency with Inhibitor.
Factor V deficiency secondary to inhibitors is extremely rare and can be caused by a wide collection of exposures such as bovine thrombin and beta lactamase antibiotics. The management of factor V deficiency with inhibitor is a condition treated based on case reports due to the rarity of this condition. We describe a complicated case of an elderly patient with severe factor V deficiency with high inhibitor titer refractory to FEIBA (anti-inhibitor coagulation complex) treated with NovoSeven concurrently with cyclosporine immunosuppression and Rituxan. Given that there are no consensus guidelines on treatment, this case offers important insight into the therapeutic approaches that can be used to treat such patients.
