The mainstay of therapy in patients with congenital hemophilia is factor replacement. However, the development of inhibitors in these patients is a major complication that represents an important challenge in hemophilia care. Development of inhibitors complicates the clinical course of severe hemophilia in up to 30% of patients with hemophilia A and up to 5% of patients with hemophilia B. Although the main short-term objective of the treatment of alloantibodies against factors VIIII and IX is to control the bleeding diathesis, the eradication of the inhibitor is the leading long-term goal. The management of severe bleeding episodes and the definitive eradication of the autoantibody are also the two main options of the clinical management of patients with acquired hemophilia, a rare but life-threatening hemorrhagic condition. The most recent options available for treating patients with acquired hemophilia and congenital hemophilia with inhibitors are addressed in this review.
