Immune Tolerance Induction Using Rfviiifc (Eloctate)

Immune tolerance induction in hemophilia

2015 The development of inhibitors is the main complication of hemophilia therapy. Inhibitors occur in 25–30% and in 2–5% of patients with severe hemophilia A and B, respectively. They render treatment and prevention of bleeds difficult. The only known therapeutic strategy able to eliminate inhibitors is immune tolerance induction (ITI) that consists in regular high-dose FVIII/FIX infusions. IT...

Low-Dose Immune Tolerance Induction in Hemophilia

In patients with hemophilia A and inhibitory alloantibodies against factor VIII, various dosage schedules are used to obtain immune tolerance. In this study, we have evaluated the results of 13 years of low-dose immune tolerance induction and factors that are predictive of a positive result. The effect of immune tolerance induction in relation to age at inhibitor development, number of exposure...

Mechanisms of Tolerance Induction by Hematopoietic Chimerism: The Immune Perspective

Hematopoietic chimerism is one of the effective approaches to induce tolerance to donor-derived tissue and organ grafts without administration of life-long immunosuppressive therapy. Although experimental efforts to develop such regimens have been ongoing for decades, substantial cumulative toxicity of combined hematopoietic and tissue transplants precludes wide clinical implementation. Toleran...

Induction by RelB-Silenced Dendritic Cells Immune Modulation and Tolerance

Immune tolerance induction for laronidase treatment in mucopolysaccharidosis I

Enzyme replacement therapy (ERT) can produce anti-drug antibody (ADA) responses that reduce efficacy or lead to hypersensitivity reactions. Six patients with severe mucopolysaccharidosis type I (MPS I/Hurler syndrome) who did not receive hematopoietic stem cell transplantation underwent an immunosuppression regimen prior to initiating ERT with laronidase. The primary endpoint for immune toleran...
