Acquired haemophilia A (AHA) is a rare and severe haemorrhagic autoimmune disease caused by autoantibodies directed against factor VIII (FVIII). Treatment is based on two principles, including haemostatic control to compensate FVIII inhibition and eradication of inhibiting antibodies using immunosuppressive therapy. Rapid recognition and proper management are essential to avoid excess morbidity and mortality. Effective and safe treatments can be challenging, given that AHA patients are often elderly, with multiple comorbidities. Emicizumab, a bispecific antibody that mimics the action of FVIII, has proven effective in managing patients with congenital haemophilia, with or without inhibitors. Likewise, its mode of action suggests theoretical efficacy in AHA patients. We herein describe two AHA cases with comorbidities that were treated effectively using emicizumab combined with immunosuppressive therapy. We have also reviewed the current literature regarding the promising use of emicizumab in this indication.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
