A cornerstone of the management of Acquired Haemophilia A (AHA) involves inhibitor eradication. First line immunosuppressive agents are usually steroids, either alone or in combination with cyclophosphamide. We present the use of Rituximab, cyclophosphamide, vincristine and prednisolone (RCVP) combination as immunosuppressant in AHA in a small cohort of patients in order to control their symptoms and eradicate inhibitors. This was a retrospective analysis of all AHA patients treated at the Northern Ireland Haemophilia centre over a six year period. During this time, a total of six patients were newly diagnosed with AHA. Four of these patients failed to respond conventional therapy of steroids and cyclophosphamide, they were however successfully treated with RCVP/ RCV. All patients achieved complete remission with this regimen after 1 to 2 cycles of treatment. Remission has been maintained for an extended time period (range 33-69 months). As AHA is related to immune modulation and, in some cases, underlying malignancy we decided to use this regime as it is effective in either condition. From our experience, we demonstrate that RCVP combination is a promising treatment in patients with AHA who fail to respond to steroids alone or who have been on pre-existing immunosuppression.

Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...
