While improvements in hemostatic agents for patients with inhibitors have resulted in decreased mortality, inhibitors are still associated with significant morbidity, including a higher rate of bleeding complications, increased disability and a decreased quality of life[ Brown et al.

Understanding and influencing blood donor behaviour. Inhibitors come in different hekophilia of severity. Because the titer stays low, they may be able to control bleeding by using larger quantities of those factor concentrates.

This study, however, has been criticized for not having contemporaneous controls, and the quite spectacular results need to be confirmed in prospective studies.

Low titer inhibitors can sometimes resolve on their own.
