Inhibitor formation in non-severe haemophilia A is a life-long risk and associated with morbidity and mortality. There is a paucity of data to understand real-world inhibitor screening practice. We evaluated the treatment burden, haemostatic strategies, F8 genotyping and inhibitor screening practices in non-severe haemophilia A in seven London haemophilia centres. In the 2-year study period, 44% (377/853) patients received at least one haemostatic treatment. Seventy-nine percent of those treated (296/377) received factor VIII (FVIII) concentrate...

Fibrin metabolism is influenced by many factors. The velocity of fibrin formation, genetic polymorphisms, fibrinolytic features and the structure of the fibrin clot are determinants of fibrin turnover. Oral contraceptives (OCs) have significant impact on the haemostatic system, by increasing the concentration of coagulation factors, plasminogen and tissue plasminogen activator activity, and decreasing the concentration of haemostatic inhibitors. The present study addresses the influence of OCs on fibrin structure and fibrin metabolism...

REVIEW
P M Mannucci, M Franchini
Von Willebrand disease (VWD) is an inherited haemorrhagic disorder caused by a quantitative or qualitative defect of von Willebrand factor (VWF), a multimeric plasma glycoprotein that plays a key role in platelet adhesion to the subendothelium and acts as a carrier of factor VIII (FVIII) in blood. Patients with VWD experience bleeding symptoms that are mainly localized in mucous membranes and soft tissues, and their severity depends on the degree of the primary reduction in VWF and the secondary deficiency of FVIII in plasma...

Haemostatic complication is common for patients with hematologic malignancies. Recent studies suggest that the procoagulant activity (PCA) of extracellular vesicles (EV) may play a major role in venous thromboembolism and disseminated intravascular coagulation (DIC) in acute leukaemia. To study the impact of EVs from leukaemic patients on thrombin generation and to assess EV-PCA as a potential biomarker for thrombotic complications in patients with acute leukaemia. Blood samples from a cohort of patients with newly diagnosed acute leukaemia were obtained before treatment (D-0), 3 and 7 days after treatment (D-3 and D-7)...
