[Characterization of immune disorders in hemophiliac patients with the identification of inhibitor-dependence in replacement transfusion therapy]

Abstract

Results are analyzed of a clinical observation and examination of 188 patients with haemophilia aged 10-77 years. The haemophilia patients were diagnosed as having developed secondary immunodeficiency related to chronic antigenic stimulation of the patient's immune system by allogenic proteins which contain plasma preparations. Against the background of immunodeficiency, there occur in the patients complications of immune character such as appearance of immune inhibitors to clotting factors. The authors are of the opinion that the nature of the inhibitory form of haemophilia is related, first, to genetic anomalies in factor VIII (IX), which cause the development of the autoimmune process; second, that as a result of alloimmunization and immunomodulating action of substitution therapy there develop persistent disorders in immunoregulation and activation of antibody genesis, which facts come to trigger off the appearance of inhibitory antibodies.
