Inhibitors are a serious medical problem that can occur when a person with hemophilia has an immune response to treatment with clotting factor concentrates. The immune system defends the body from harmful germs and viruses.
What is an Inhibitor? The body protects itself from disease with a host of defenses that are collectively called the immune system. The immune systems first lines of defense are barriers, such as the skin and mucus membranes. However, this is not the body's only defense. Once something has made its way past these barriers, the body mounts a cellular immune response. This cellular response results in the production of antibodies. An antibody is produced in response to the presence of foreign substance in the body.
