Filter by:The main objectives of the study were - to compare the pharmacokinetics (PK) of Optivate® and Haemate P® in various types of vonWillebrand disease (VWD) using the results from the VWF: RCo, VWF:Ag, VWF:CBA and Factor VIII assays. - to compare the clinical tolerance and safety of these two treatments after single IV infusions in subjects with VWD.
The main objective of the study is to compare the pharmacokinetics of Optivate® with the subject's current FVIII concentrate when given as a bolus dose of 50IU/kg. The secondary objective is to compare the first and second pharmacokinetic assessments on Optivate® (and recovery if a subject changes batch) to evaluate Optivate® in terms of clinical tolerance and safety.
Patients with hemophilia who have the same level of deficient factor(s) may express different severity of clinical presentation and bleeding tendency. Therefore a test which could determine overall hemostasis rather than simple concentration of a single deficient factor may correlate better with clinical phenotype in these patients. The investigators will therefore study the usefulness of global hemostatic methods (endogenous thrombin potential (ETP), overall hemostatic potential (OHP), fibrin clot structure) and microparticles in the prediction of severity of bleeding and estimation of response to the treatment in patients with hemophilia. Since hemophilia patients on prophylactic treatment virtually do not bleed, additional patients who are treated on demand only will be included enabling to study possible modulatory effects of different hemostatic factors (particularly prothrombotic and thrombin activatable fibrinolysis inhibitor (TAFI)) on clinical presentation. The investigators will correlate both those factors and clinical severity with global hemostatic methods. The investigators expect to prove that individual tailoring of the treatment, which may enable lowering the prophylactic dose of factor concentrate without increasing the risk of bleeding, is justified in some hemophilia patients. This approach would reduce the amount of necessary factor concentrate in certain patients and decrease the cost (which represents extensive burden for health care systems) of treatment without potential risk for the patients.
Acquired Von Willebrand disease (type 2A) has been described in patients with severe aortic stenosis, the association of aortic stenosis and Digestive bleeding due to this phenomena has received the name of Heye´s syndrome. We propose that administering Desmopressin (DDAVP) in patients scheduled to aortic valve replacement surgery will reduce blood loss and transfusion rate. this was a pilot study

Hemofix is a herbal formula based on traditional Jewish and far eastern medicine created to assist in wound healing and bleeding arrest. It contains herbs such as Red Clover, Liquorice, Raspberry, Ginger and more. The present study will evaluate the formula on the coagulation system.
This is an observational study, hence there is no study hypothesis
1. Hypothesis a. There are patients with von Willebrand Disease in Cuenca. 2. Primary question a. How many women referred with a history of bleeding may have von Willebrand disease? 3. Secondary 1. Associations between the bleeding score and initial laboratory studies 2. What are the differences on subgroups of enrolled patients with the bleeding score? 4. Ancillary 1. What is the clinical and socio-economic status of women with von Willebrand Disease in Cuenca? 2. What is the clinical and socio-economic status of patients with Hemophilia in Cuenca?
The purpose of this Phase 3 study is to assess the pharmacokinetics of rVWF:rFVIII and rVWF, and to assess the safety and efficacy of rVWF:rFVIII and rVWF in the treatment of bleeding events in subjects with severe hereditary von Willebrand disease (VWD).
Proportion of surgeries in which the primary endpoint (overall assessment) is classified as success.
