Objective: To collect data from nine European countries for cases of obstetric hemorrhage between 2000 and 2004 in which recombinant activated factor VII (rFVIIa) was used.
Methods: The cases were identified through national surveys. Standardized case report forms included sociodemographic details, past medical and obstetric history, and details of the progress and management of labor in which the postpartum hemorrhage occurred. Clinicians were asked to describe subjectively the effect of rFVIIa administration using two mutually exclusive categories: 1) bleeding reduced or 2) bleeding unchanged or worse.
Results: A total of 113 forms were returned (88%) with 97 (86%) classified as treatment, and 16 (14%) as "secondary prophylaxis." Clinicians noted improvements after a single dose for 80% of women in the treatment group, and for 75% in the secondary "prophylaxis" group. However, rFVIIa failed in 15 cases (13.8%). Few serious adverse events were noted related to rFVIIa administration; there were four cases of thromboembolism, one myocardial infarction, and one skin rash.
Conclusion: Clinical reports and hematologic data suggest improvement for more than 80% of women after rFVIIa administration and few adverse effects.
Level Of Evidence: II.

Hemophilia is caused by the deficiency of clotting factors due to a single genetic abnormality. Replacement therapies have evolved from plasma-derived to recombinant coagulation factor concentrates but continue to have certain limitations. Monoclonal antibodies are clinical prophylactic treatment options unaffected by inhibitors and have better compliance than coagulation factor concentrates for patients with hemophilia.

Background: Death in the early phase of trauma is primarily attributable to uncontrolled bleeding exacerbated by trauma-induced coagulopathy (TIC). A comprehensive synthesis of the available evidence on interventions for TIC is needed.
Methods: We conducted a systematic review and meta-analysis of blood component products and tranexamic acid administrations for severe trauma patients with TIC.

Hemophilia A (HA) patients under emicizumab prophylaxis may require the concomitant use of procoagulant factors for breakthrough bleedings or immune tolerance induction (ITI). The aim of this study is to evaluate the ex vivo procoagulant effect of plasma-derived FVIII concentrates containing von Willebrand factor (pdFVIII/VWF) in samples from patients with severe HA without inhibitors on emicizumab prophylaxis. Samples from healthy controls (HC) and HA patients were drawn in sodium citrate plus corn trypsin inhibitor tubes and spiked with increasing concentrations of pdFVIII/VWF concentrates (10-400 IU/dL) (Fanhdi/Alphanate, Grifols), activated prothrombin complex concentrate (aPCC, 0.

In patients with hemophilia A with inhibitor (PwHA-I), emicizumab drastically reduces bleeding events. However, few studies have investigated the behavior and effects of factor X (FX) in patients who require intensive treatment with factor VIII-bypassing agents (BPA) and emicizumab. A 59-year-old man with HA-I receiving emicizumab prophylaxis was admitted to our hospital because of acute gangrenous cholecystitis.

Glanzmann's thrombasthenia (GT) is a rare autosomal recessive disorder of platelet function. The frequent occurrence of alloimmunization due to repeated platelet transfusions is the major complication of the disease. Achieving hemostasis in these patients with anti-GPIIb-IIIa antibodies during surgical procedures is a significant challenge due to the high risk of bleeding.
