Official Title: Whole Blood Clot Stability and Thrombin Generating Capacity Following Treatment With Bypassing Agents (BPA) With and Without and Tranexamic Acid (TXA) in Haemophilia A Patients With inhibitor-an In-vi
Brief Summary: Activated prothrombin complex concentrate (aPCC) and recombinant activated factor VII (rFVIIa) are the only two drugs that are available to treat bleeds in haemophilia A patients with high titer inhibitors. However, management of bleeds in these patients can be challenging due to variation in response and lack of standardized methods to monitor the effect. We hypothesized that significant increase in whole blood clot stability could be achieved when tranexamic acid was given concomitantly with bypassing-agents while thrombin generation remains unaffected. In this prospective crossover study the effect of aPCC and rFVIIa with and without TXA on clot stability and thrombin generation capacity (ETP) were studied, using thromboelastography (ROTEM) and thrombin generation assay (TGA), respectively. In addition, the risk of thrombosis and disseminated intravascular coagulation (DIC) was assessed.
