Extractions: Ty pes of von Willebrand disease The biochemical heterogeneity of von Willebrand disease became apparent in the late seventies and early eighties. This led to a complex mode of classification. However with continued research into the biosynthesis and function of von Willebrand Factor has led to a more simplified classification. The main three categories are based on whether the patient suffers from; a quantitative deficiency; a qualitative deficiency or a total deficiency of von Willebrand Disease. Type 2 is divided into four variants based upon details of the phenotype. There is also an acquired form of von Willebrand Disease. Classification of von Willebrand Disease TYPE DEFICIENCY QUANTITATIVE QUALITATIVE QUALITATIVE QUALITATIVE QUALITATIVE TOTAL DEFICIENCY Type 1; Type 1 von Willerband disease is the most commonest type affecting approximately 70-80% of the population. Likewise type 1 produces the mildest effects. In type 1 the distribution of multimers is normal and all molecular forms are decreased proportionally. This reduction of multimers is different in each patient and may be variable on different occasions in each patient. Diagnosis of type 1 is impaired as plasma levels of Factor VIII

Treatment Of Von Willebrand Disease
Most people with von willebrand Disease display very mild symptoms, unless they are suffering form type 3.
http://www.biol.napier.ac.uk/courses/projects99/vwillibrand/treatmen.htm

Extractions: Sy mptoms, testing and treatment Symptoms Testing Treatment Symptoms Most people with von Willebrand Disease display very mild symptoms, unless they are suffering form type 3. Many people do not realise that they are suffering from the disease until another family member is diagnosed. These symptoms are highly variable even within a family and not every sufferer displays every sign. von Willebrand disease is associated with easy bruising, recurrent nosebleeds, mucocutaneous haemorrhage and prolonged or posttraumatic bleeding. plasma von Willebrand Factor and Factor VIII levels increase during pregnancy. In patients suffering from type 3 spontaneous hemorrhage from mucous membranes and gastrointestinal tract is quite common and can be life threating. For women suffering from this type and for those people whom have just undertaken surgery bleeding is controlled by hormone replacement therapy. Sufferers are advised against competing in any sport that carries a high risk of injury. This is to prevent injury that would be followed by the above symptoms.

Extractions: What is von Willebrand Disease? von Willebrand Disease is an inherited deficiency or defect of a blood clotting substance called von Willebrand factor. Its' symptoms include easy bruising, frequent nose bleeds, bleeding gums, gastrointestinal bleeding, prolonged menstrual bleeding, and excessive bleeding following surgery. Unlike hemophilia, von Willebrand Disease occurs equally amongst males and females and is much more common than hemophilia, occurring in 1 in every 50 births. von Willebrand Disease (vWD) should be suspected in anyone who has the following symptoms: The severity of symptoms varies from person to person. Anyone can get vWD; both males and females. It affects an estimated 1 out of every 50 people. That's millions of Americans! Where Does vWD Come From?

http://www.shef.ac.uk/vwf/vwd.html

Extractions: United Kingdom Fast link: Back to index Mutations Polymorphisms Nomenclature VWF Sequences Diagrams Useful links Database submission References Downloads Searches Sponsor Credits VWD is a congenital bleeding disorder which results from quantitative or qualitative defects of von Willebrand factor (VWF). It is the most common inherited bleeding disorder in humans with a prevalence ranging from 3-4 per 100,000 to 1.3% of the population (reviewed in Keeney and Cumming, 2001). More than 20 subtypes of VWD have been described, although current classification consists of 6 distinct types (Sadler, 1994). Types 1 and 3 are quantitative VWF defects whilst the four type 2 variants are qualitative VWF defects. For more information, see the review by Keeney and Cumming, 2001. For example multimer diagrams, click here Back to index VWD Classification Description Type 1 Partial quantitative deficiency of VWF. Typically autosomal dominant in inheritance although diagnosis is complicated by reduced penitrance and variable expressivity. Characterised by parallel reductions in VWF:Ag and Factor VIII. Multimer distribution is normal. Type 2A Qualitative VWF defect associated with absence of the largest multimers and low levels of VWF:Ricof activity relative to VWF:Ag. Generally autosomal dominant, caused by missense mutations within the VWF A2 repeat. Group 1 (defect in intracellular transport) or group 2 (increase in proteolysis in plasma after secretion).

http://www.hemophilia.org/bdi/bdi_types3.htm

Extractions: von Willebrand's disease is a hereditary deficiency or abnormality of the von Willebrand factor in the blood, a protein that affects platelet function. It's the most common hereditary disorder of platelet function, affecting both women and men. The disease is estimated to occur in 1% to 2% of the population. In von Willebrand disease, blood platelets don't stick to holes in blood vessel walls. Platelets are tiny particles in the blood that clump together at the site of an injury to prepare for the formation of a blood clot. von Willebrand factor causes them to bind to areas of a blood vessel that are damaged. If there is too little von Willebrand factor, or the factor is defective, platelets do not gather properly when a blood vessel is injured. von Willebrand factor is found in plasma, platelets, and blood vessel walls. When the factor is missing or defective, the first step in plugging a blood vessel injury (platelets adhere to the vessel wall at the site of the injury) doesn't take place. As a result, bleeding doesn't stop as quickly as it should, although it usually stops eventually.

http://www.hemophilia.org/resources/vwd.htm

Extractions: Young women with vWD can have menstrual periods that last for weeks, or in some cases, for months at a time. Continuous bleeding can lead to severe anemia. Prolonged menstrual bleeding can make becoming pregnant impossible and/or can increase the risks of miscarriage. Painful menstrual periods, a sense of isolation due to not knowing that others have similar problems, and frustration with the medical system are common quality of life concerns.

Extractions: Bleeding Disorder W hat is the most common inherited bleeding disorder, the one that affects many millions of people around the world, and up to two million in the United States? You may be surprised to hear that it is not haemophilia. It is von Willebrand disease , a related disorder that few people have heard of, unless they have it or know someone who does. Why is such a common illness such a secret? Perhaps because the disease is usually less severe than haemophilia, it has not generated the kind of publicity, educational efforts and support that other chronic illnesses have. In fact, it is often so mild, it is not diagnosed at all. Some people live with the disease for many years before getting an accurate diagnosis. For more severely affected patients, this lack of knowledge has caused real suffering. Alice Arabshian, a college student was diagnosed with clinically severe von Willebrand disease when she was a year old, says of her early childhood in Cyprus where almost nothing was known about von Willebrand: "There were no facilities for people with this illness. It was virtually impossible to get proper treatment." Fortunately, substantial progress has been made in recent years. The von Willebrand gene has been identified and research is underway to develop gene therapy. As research continues, however, the challenge continues to educate healthcare professionals and the public about this disorder. That is the best way to assure those with von Willebrand that they will receive proper diagnoses and treatment.
Von Willebrand's Disease

Extractions: von Willebrand's Disease by Jennie Bullock von Willebrand's disease is a bleeding disorder found in many breeds of dog as well as other animals. It is characterized by hematomas, nosebleeds, and intermittent limping (due to bleeding into the joints). Similarly to hemophilia A, dogs with this disorder are deficient in clotting factor VIII activity. One of the primary distinctions of von Willebrand's disease however, is that this disorder is not sex-linked. von Willebrand's disease appears in two variations: inherited and acquired. In its acquired presentation von Willebrand's is a complication of thyroid deficiency. With proper treatment and stabilization of the dog's thyroid levels the von Willebrand's is negated. Hereditary von Willebrand's disease is far more complex. Each breed of dog will have a different set of "typical symptoms" of the disease. Symptoms can range from abnormally long bleeding time due to a cut toenail, to hemorrhaging during minor surgery, to spontaneous nosebleeds, with a wide assortment of presentations between. Injuries that are followed by bleeding may or may not require a transfusion. Even a small wound may necessitate veterinary treatment. Carriers of this disorder can live their entire lives with no outward indications of this disease. von Willebrand's disease can be fatal. There is no cure and no effective treatment. It appears that DNA screening is the most accurate means of testing currently.

Extractions: Susanne J. Pavlovich-Danis, ARNP-C, MSN Could these three very different patients have something in common? Are their symptoms being evaluated or treated when a true underlying problem remains unnoticed? von What? Erik von Willebrand, MD, first described vWD in 1925 after studying a family of women from Aland Islands, Finland, who had extreme menstrual bleeding. One member was a 12-year-old girl who died during her first menstrual period. vWD occurs in 1% to 2% of the US population. Unlike hemophilia, it occurs equally among genders, yet women are affected more severely because of menstruation and childbirth. Research has shown that white women (15.9%) are more likely than black women (1.4%) to have vWD. Many with the disorder are unaware of the true cause of their symptoms or that treatment is available. While there is no cure, it can be treated. Without proper diagnosis, people with vWD can die unnecessarily during surgery, trauma, or menses. Hemostasis and the vW Factor Normal blood clotting requires a series of reactions among blood factors, proteins, and platelets to form the platelet plug that ultimately creates a fibrin clot that, in turn, stops blood from leaking from vessels. In vWD, an interruption in the normal clotting process causes bleeding into the skin and from mucous membranes, especially the nose, mouth, gums, gastrointestinal/genitourinary tract linings, and the uterus. von Willebrand factor (vWF) is a glue-like, high-molecular-weight protein necessary for platelet adhesion and formation of the platelet plug. Produced by cells lining vessel walls, it is also a carrier protein for plasma factor VIII (classic hemophilia A factor).

Extractions: VON WILLEBRAND DISEASE IN WOMEN An Introduction to the Basics vWd in Women Von Willebrand disease (vWd) is characterized by the inability of the blood to clot normally. Blood is a fluid carried through the body in tubes called arteries, veins, and capillaries. When a tube is injured, a small hole forms, letting blood flow out. Stopping the flow of blood, or clotting, is necessary. Blood clotting is a process that requires the following three steps to be successful. Vasoconstriction - the blood vessel narrows and slows the passage of blood from the hole Clot - clotting factors and proteins in the blood, stop at the site, form a solid fibrin clot, and seal the hole, stopping the flow blood If any of these steps is missed or does not work correctly, no clot is formed. The missing, defective, or poorly working element in vWd is a protein called vWf. VWf is a substance made by the lining cells of the blood vessels. VWf acts as a "catcher’s mitt" to bind platelets to the internal site of the "hole in the vessel" creating a plug. A person with vWd may experience the inability to form a platelet plug from several kinds of events. Such events may include bleeding from injury, surgery, or from a spontaneous bleed. VWf also carries and protects Factor VIII (FVIII). Lack of FVIII will additionally cause a disruption in the entire clotting chain (cascade) making clot formation slow or unlikely. Without medical treatment to promote and sustain clotting, internal bleeding may continue and may cause long-term damage.
