Although generally presented as an independent disease, von Willebrand disease actually belongs to a family of blood disease caused by an abnormality of von Willebrand factor. Von Willebrand disease is the most common hereditary transmitted blood disease. It is a blood disorder characterized by the tendency to bruise easy, frequent nosebleeds and prolonged menstrual bleeding due to quantitative or qualitative abnormalities, depending on the type of von Willebrand factor. Von Willebrand factor is a protein that functions as a “carrier” for coagulation factor VIII.
Von Willebrand disease is transmitted autosomal; gene on chromosome 12 is affected. Depending on the type of von Willebrand disease, may be recessive or dominant transmission. The disease is found at a frequency of one case per 8 00 – 1000 people. It meets with equal frequency in both men and women, unlike hemophilia A or hemophilia B which are occurring more frequently in males. Global prevalence is estimated around 1%. No differences based on race.
Signs and symptoms
The clinical picture can be extremely varied, even within a family. The most frequently describe these events:
Increased tendency to bruise easily
Recurrent epistaxis (nosebleeds repeated)
Prolonged menstrual bleeding (lasting more than 7 days)
Postoperative bleeding or after dental extractions
Bleeding gums (especially in infants and erupting teeth)
Bleeding at birth and immediately after birth
Prolonged bleeding wounds
To see that von Willebrand disease is frequently associated with the following diseases:
Willms Renal Tumor
Congenital heart disease
Systemic lupus erythematosus (SLE)
Epilepsy treated with valproic acid
Von Willebrand disease is divided into three categories: partial quantitative deficiency type I, qualitative deficiency type II and total deficiency type III. Type III is divided into four types: IIA, IIB, IIN, IIM depending on the characteristics of dysfunctional von Willebrand factor. These categories correspond to distinct molecular mechanisms, with correspondent and clinical regimens.
For affected individuals von Willebrand disease is a mild bleeding disorder well controlled. However, there is variability in members of the same family events. In people with type II or III bleeding may be severe and potentially life-threatening. People with type III von Willebrand factor which decreased develop arthropathy. Morbidity and mortality in this disease varies. Most children with von Willebrand disease are asymptomatic. Some shows mucosal bleeding: epistaxis and bruising. Menorrhagia is common in women with von Willebrand disease. Occurs in over 50% of women with von Willebrand disease and may be the only clinical manifestation of the disease. Type III rarely can result in severe bleeding similar to hemophilia: hemarthrosis, intramuscular hemorrhage.
Treatment and Prevention
In minor bleeding and easy epistaxis, no therapeutic intervention is need. In serious bleeding, should be given a number of medications that increase the level and activity of von Willebrand factor.
The goal of treatment is to correct the platelet adhesion defect by increasing levels of von Willebrand factor efficient and correct the coagulation defect by increasing levels of factor VIII needed for a proper hemostasis. In patients with severe bleeding, appropriate and prompt treatment is important to avoid potential complications.
The easiest preventive method for the patient is easy restriction in sports activities, especially in patients with type 3 von Willebrand diseases and to prevent the use drugs with antiplatelet effect of NSAIDs type (Aspirin, Ibuprofen, Naproxen), antihistamines, antibiotics of cephalosporin type, tricyclic antidepressants. A more complete list of medications with antiplatelet effects will be provided to patients by their hematologist.
