title: Adaptability of protein A-immunoadsorption allows temporary reduction of anti-VIII antibodies and realisation of high-risk haemorrhagic surgery.
abstract: We report the successful treatment by protein A-immunoadsorption (IA) of an hemophilic man with anti-F VIII antibodies (Abs) who needed high-risk bleeding surgery. This patient had developed high levels of anti-F VIII Abs preventing substitution by clotting factor and preventing high-risk bleeding surgery. Because of rebound in Abs levels or complications, IA procedures were modified several times leading to appropriate decrease of anti-F VIII inhibitor Abs allowing bilateral knees surgery. IA procedure is enough adaptable to be modified to prevent complications. Collaboration between clinical, biological, apheresis and surgical teams implied has permitted surgery and prevented life-threatening bleeding complications.
