Immune inhibitors are antibodies developed in hemophilia patients. Hemophilia is a hereditary blood-related disorder that occurs due to deficiency or absence of clotting factor VIII (hemophilia A) or clotting factor IX (hemophilia B). The condition can be classified according to amount of clotting factor present although classification is not limited to the type of deficient clotting factor. For instance, hemophilia A can be classified as mild hemophilia (5-25% of normal values), moderate hemophilia, (1-5% of normal values), and severe hemophilia (<1% of normal values) depending on factor VIII levels in patients.
The immune inhibitors in hemophilia patients act against the administered therapy. Hemophilia patients are controlled either plasma-determined or recombinant substitution blood factor concentrates as drug treatment, which help in blood coagulating. In any case, the inhibitors erroneously target substitution factor concentrates as an unfamiliar substance. These antibodies are created after the patient has been managed with blood factor FVIII concentrate. Inhibitors act following 10 to 20 days of first openness to factor substitution treatment. The vast majority of these inhibitors stay in the blood for brief time frame and vanish without treatment. Notwithstanding, more persevering inhibitors is a genuine antagonistic occasion concerning treatment of Hemophilia A.
