Excess Morbidity

Acquired haemophilia A (AHA) is a rare and severe haemorrhagic autoimmune disease caused by autoantibodies directed against factor VIII (FVIII). Treatment is based on two principles, including haemostatic control to compensate FVIII inhibition and eradication of inhibiting antibodies using immunosuppressive therapy. Rapid recognition and proper management are essential to avoid excess morbidity and mortality. Effective and safe treatments can be challenging, given that AHA patients are often elderly, with multiple comorbidities. Emicizumab, a bispecific antibody that mimics the action of FVIII, has proven effective in managing patients with congenital haemophilia, with or without inhibitors. Likewise, its mode of action suggests theoretical efficacy in AHA patients. We herein describe two AHA cases with comorbidities that were treated effectively using emicizumab combined with immunosuppressive therapy. We have also reviewed the current literature regarding the promising use of emicizumab in this indication.

Acquired Factor Viii Inhibitor

A 77-year-old man with a mechanical mitral valve on warfarin presented with an acute drop in haemoglobin and large spontaneous haematoma. He was found to have a new coagulopathy with initial labs notable for a prolonged activated partial thromboplastin time (APTT). Further workup revealed factor VIII levels less than 1%, abnormal mixing studies and elevated Bethesda titres, which was consistent with an acquired factor VIII inhibitor. Given his bone marrow biopsy result, which was positive for plasma cell myeloma, this coagulopathy was thought to be an acquired haemophilia A secondary to multiple myeloma. Anticoagulation was a challenge in this patient given his mechanical mitral valve and acquired haemophilia A. Although the patient was at risk of thrombosis due to a mechanical mitral valve, he had a bleeding diathesis and anaemia not responsive to transfusion. The decision was made to hold anticoagulation and the patient was started on myeloma treatment which included CyBorD, rituximab and daratumumab. After initiation of treatment APTT and factor VIII normalised. He eventually restarted anticoagulation under direction of his primary care doctor.

History Of

SummaryTwenty six patients with mild or moderate haemophilia A and inhibitors are described. The inhibitor was detected at a median age of 33 years, after a median of 5.5 bleeding episodes. This usually following intensive replacement therapy. The median presenting inhibitor titre was antihuman 11.6 BU/ml, antiporcine 1.45 BU/ml. Plasma basal factor VIII level declined from a median of 0.08 IU/ml to 0.01 IU/ml following the inhibitor development. This caused spontaneous bleeding in 22 and a bleeding pattern similar to acquired haemophilia in 17. Bleeding was often severe and caused two deaths.The inhibitor disappeared spontaneously, or following immune tolerance induction, in 16 cases after a median of 9 months (range 0.5-46), with a return to the original baseline VIIIC level and bleeding pattern accompanied inhibitor loss. The inhibitor persisted in the remainder of the cases over a median period of 99 months (range 17-433 months) of follow-up. Inhibitors are an uncommon complication of mild haemophilia which frequently persist and may be associated with severe, life-threatening, haemorrhage.Forty-one percent of treated haemophilic family members had a history of factor VIII inhibitors, suggesting a familial predisposition to develop inhibitors in these kindreds. Sixteen patients from 11 families were genotyped. Seven different missense mutations affecting the light chain were detected and two in the A2 domain. Five patients from three families had a mutation causing a substitution of Trp2229 by Cys in the C2 domain which appears to predispose to inhibitor formation since 7 of the 18 affected individuals have a history of inhibitor development.
