OBJECTIVES: I. Evaluate the effect of a new von Willebrand factor concentrate on bleeding time, in vivo recovery, and circulating half-life of the infused factor in patients with von Will...
The objective of this study is to assess the clinical presentation, the treatment and the complications of the disease and treatment in moderate and severe von Willebrand disease. Another ...
The objectives of this study are to evaluate the immediate tolerability and safety of rVWF:rFVIII in subjects with Type 3 Von Willebrand Disease after administration of various dosages of ...
The investigators are going to study von Willebrand antigen and activity levels in patients with inflammatory bowel disease. The study will be on 46 patients who were diagnosed with inflam...
This is an outpatient, 24-week Phase III prospective, randomized, crossover trial comparing recombinant von Willebrand factor (rVWF) and tranexamic acid (TA, Lysteda®) to minimize menorrh...
Von Willebrand disease (VWD) is the most common inherited bleeding disorder and is divided into three types, namely type 1, type 2 (2A, 2B, 2M, 2N), and type 3. We report a case of a 24-year-old Cauca...
von Willebrand disease (VWD) is an inherited bleeding disorder caused by a quantitative (type 1 and 3) or qualitative (type 2) defect of von Willebrand factor (VWF). The heterogeneity of laboratory...
Patients with Type 1 von Willebrand disease (VWD) have reduced amounts of von Willebrand factor (VWF) in their blood. Desmopressin (DDAVP) has been used to raise the blood levels of VWF in these patie...
The haemorrhagic phenotype in patients with von Willebrand disease (VWD) is heterogeneous, and assays of von Willebrand factor ristocetin cofactor activity (VWF:RCo) do not always reflect clinical sev...
It has been hypothesized that persons with von Willebrand disease (VWD) may be protected against arterial thrombosis despite having atherosclerosis.
A subtype of von Willebrand disease that results from a partial deficiency of VON WILLEBRAND FACTOR.
A subtype of von Willebrand disease that results from qualitative deficiencies of VON WILLEBRAND FACTOR. The subtype is divided into several variants with each variant having a distinctive pattern of PLATELET-interaction.
A subtype of von Willebrand disease that results from a total or near total deficiency of VON WILLEBRAND FACTOR.
A high-molecular-weight plasma protein, produced by endothelial cells and megakaryocytes, that is part of the factor VIII/von Willebrand factor complex. The von Willebrand factor has receptors for collagen, platelets, and ristocetin activity as well as the immunologically distinct antigenic determinants. It functions in adhesion of platelets to collagen and hemostatic plug formation. The prolonged bleeding time in VON WILLEBRAND DISEASES is due to the deficiency of this factor.
Group of hemorrhagic disorders in which the VON WILLEBRAND FACTOR is either quantitatively or qualitatively abnormal. They are usually inherited as an autosomal dominant trait though rare kindreds are autosomal recessive. Symptoms vary depending on severity and disease type but may include prolonged bleeding time, deficiency of factor VIII, and impaired platelet adhesion.
