Overview
VWD is caused by a quantitative or qualitative defect in vWF. Most cases of vWD are due to inherited mutations that affect production of vWF. There are also acquired forms of vWD where vWF is impaired due to other pathological processes. Acquired defects in vWF can be caused by a number of conditions,for example mitral valve prolapse, ventricular assist device, ventricular septal defect, aortic stenosis, monoclonal gammopathy of undetermined significance, chronic myeloid leukemia and chronic lymphocytic leukemia, wilms tumor, waldenström macroglobulinemia, essential thrombocythemia, multiple myeloma, non-Hodgkin lymphoma, polycythemia vera, valproic acid, ciprofloxacin, griseofulvin, systemic lupus erythematosus,hypothyroidism, uremia, hemoglobinopathies and angiodysplasia.
Causes
VWD is caused by a quantitative or qualitative defect in vWF. Von Willebrand Factor binds platelets to collagen and is important in primary hemostasis. It also serves as a carrier for Factor VIII and prevents it form being degraded. Most cases of vWD are due to inherited mutations that affect production of vWF. There are also acquired forms of vWD where vWF is impaired due to other pathological processes. Acquired defects in vWF can be caused by a number of conditions including:[1][2][3][4][5][6][7]
- Mitral valve prolapse
- Ventricular assist device
- Ventricular septal defect
- Aortic stenosis
Malignant diseases
- Monoclonal gammopathy of undetermined significance
- Leukemia example chronic myeloid leukemia and chronic lymphocytic leukemia
- Wilms tumor
- Waldenström macroglobulinemia
- Essential thrombocythemia
- Multiple myeloma
- Non-Hodgkin lymphoma
- Polycythemia vera
Drugs and other agents
Autoimmune disorders
