Venous thrombosis is a very rare occurrence in patients with haemophilia A. The majority of these cases occurred during or after the administration of clotting factor concentrates. We report the case of a patient with severe haemophilia A, who spontaneously developed a deep venous thrombosis (DVT). The thrombosis occurred in the superficial femoral vein(More)
There is currently no validated method to detect a prothrombotic phenotype. The question remains, can tissue factor (TF) induced thrombin generation (TG), as measured with the calibrated automated thrombinography (CAT) technique, according to Hemker et al., recognise a prothrombotic state either as such, or when the activated protein C (APC)-system is(More)
In haemophilia patients, a relationship is usually observed between the clinical expression of the disease and plasmatic factor VIII/factor IX (FVIII/FIX) activity. However, it is known from clinical experience, that some haemophilia patients, despite similar FVIII/FIX plasma levels, could exhibit different bleeding phenotype. After determining(More)
Recombinant factor IX (rFIX) is increasingly used to treat patients with hemophilia B. CHO (Chinese Hamster Ovary) cells are commonly used for the production of rFIX but they have a limited capacity for introducing post-translational modifications (PTM) leading to incomplete γ-carboxylation, low phosphorylation and sulfation profiles as compared with(More)
INTRODUCTION Hemophilia B is an inherited X-linked recessive bleeding disorder, due to a defect in human factor IX (FIX). The main treatment for hemophilia B is replacement therapy using FIX concentrates. Prophylactic treatment in severe hemophilia B is very effective but is limited by cost issues. Production of a recombinant FIX (rFIX) with enhanced(More)
Patients with thrombophilia and/or a history of venous thromboembolism (VTE) exhibit a high risk of thrombosis during pregnancy. The present multicentre study prospectively assessed a prophylaxis strategy, based on a risk score, in pregnancies with increased risk of VTE. Among 286 patients included in the study, 183 had a personal history of VTE (63.98%)(More)
The thrombin generation test (TGT) has demonstrated utility in evaluating overall hemostatic capacity both in bleeding and thrombotic disorders. Although the test is currently well accepted as a research tool, its role in clinical practice has not yet been defined through large prospective multicenter clinical studies. Such prospective studies have been(More)
