Combination of Novoseven and Feiba in Hemophiliac Patients with Inhibitors

The aim of this study is to investigate the effective therapeutic combination of recombinant VIIa(Novoseven) and factor eight inhibitor bypass activity(FEIBA) drugs for the bleedings of adult hemophiliac patients with inhibitors.19 bleeding episodes of 5 hemophilia A patients who were using bypassing agents and followed-up between 2008 and 2016 in Hacettepe Hematology Department were analyzed retrospectively. In 11, 5 and 3 bleeding episodes, FEIBA, recombinant factor VIIa and FEIBA+recombinant factor VIIa were given to the patients, respectively. The treatment durations differed between 1 and 14 days depending on the bleeding and clinical course of the patients. Generally the treatment with bypassing agents was successful, and only in one patient who had elbow hematoma encountered serious bleeding which was taken under control by switching the bypass agent. We offer a different approach because of three reasons. Firstly, in our protocol we start the treatment with recombinant factor VIIa for the first three days. Secondly, our protocol is adjusted to consider health economics. Thirdly, we extended the time interval between doses of both bypassing agents without increasing bleeding risks because the half-life of both agents enables us to modify the protocol with more flexibility. To conclude, we have evaluated our clinic’s data about hemophilia A patients with inhibitors and we offer a different protocol in the management of bleeding episodes for these patients.
