Von Willebrand Disease : Causes-Symptoms-Diagnosis-Treatment

 What Is Von Willebrand Disease(VWD)?

Von Willebrand sickness (VWD) is a commonplace inherited condition that may make you bleed greater without difficulty than normal.

People with VWD have a low stage of a substance referred to as the von Willebrand component of their blood, or it does not work thoroughly.

Von Willebrand Disease

The Von Willebrand component facilitates blood cells to stick collectively (clot) whilst you bleed. If there may be now not enough of it now or it does not paint well, it takes longer for bleeding to stop.

There's currently no therapy for VWD, but it does not commonly motivate extreme problems and most of the people with it may live everyday, active lives.

Medical terms

  • Von Willebrand disorder is a bleeding disorder because of the qualitative or quantitative deficiency of the seasoned-von Willebrand thing. Affected human beings can also whinge of excessive bruising, prolonged bleeding from mucosal surfaces, and extended bleeding after minor trauma. This activity describes the assessment and management of Von Willebrand sickness and explains the function of the interprofessional team in improving the care of sufferers with this circumstance.
  • Von Willebrand disorder is a lifelong bleeding disorder in which your blood doesn't clot nicely. People with the ailment have low ranges of von Willebrand aspect, a protein that helps blood clot, or the protein would not perform because it needs to.
  • Most people with the disease are born with it, having inherited it from one or both mother and father. However, caution symptoms, which include heavy bleeding after a dental technique, might not show up for years.

Von Willebrand sickness can't be cured. But with treatment and self-care, most of the people with this disease can lead energetic lives.

People with von Willebrand disease can also bleed more than regular. For instance, they will have common nosebleeds or bleed for a long time after you have a minor cut. Women or human beings targeted females at start (DFAB) may also have heavy menstrual intervals or heavy bleeding after giving delivery. People who have the maximum severe shape of von Willebrand sickness may additionally have bleeding into their joints or soft tissues that cause severe ache and swelling. Some human beings broaden anemia.

symptoms When the disorder is present at birth symptoms of von Willebrand disease are often mild and may not be obvious The bleeding problems that result from von Willebrand disease however can lead to episodes of severe bleeding Common signs of these problems include nosebleeds frequent bruising and heavy periods As people with von Willebrand disease get older blood clotting becomes more difficult This can lead to frequent nosebleeds and bruising as well as bleeding in other areas of the body including the joints gastrointestinal tract or central nervous system.

Types Von Willebrand disease(VWD)

Three main types of von Willebrand disease exist:


  • Type 1 VWD is found in 60%-80% of patients. People with kind 1 VWD have a low degree of VWF of their blood. Levels of VWF inside the blood vary from 20%-50% everyday. The symptoms are commonly moderate. There is one subtype referred to as Type 1C wherein the VFW has growth clearance leading to extended bleeding.

  • Type 2 VWD is found in 15%-30% of patients. People with kind 2 VWD have a regular range of VWF, but the component isn't characteristic because it has to. Type 2 is divided into four subtypes: kind 2A, kind 2B, type 2M and sort 2N, relying on the precise way the VWF is faulty. Symptoms are slight to mild.

including types:

  • 2A

  • 2B

  • 2M

  • 2N

  • Type 3 VWD is found in 5%-10% of patients. People with three VWD have very low degrees or no  VWF in their blood.. Some people with this kind of VWD will also be low in thing VIII (issue eight). Symptoms are typically extreme, and encompass spontaneous bleeding episodes, regularly into their joints and muscle tissue.

  • Acquired VWD. This type of VWD in adults results after a prognosis of an autoimmune sickness, such as lupus, or from coronary heart sickness or a few types of cancer. It also can occur after taking certain medications.

Symptoms Von Willebrand disease(VWD)

If you've got von Willebrand disease, your symptoms will range depending on which kind of sickness you have.

Many people with von Willebrand disease do not know it because the signs are moderate or absent. The maximum commonplace signal of the circumstance is peculiar bleeding.

There are 3 predominant types of the disorder. The amount of bleeding varies from one man or woman to another, depending on the kind and severity of the sickness.

If you have von Willebrand disease, you would possibly have:

  • Excessive bleeding from an injury or after surgery or dental work

  • Frequent nosebleeds that don't stop within 10 minutes

  • Heavy or long menstrual bleeding

  • Heavy bleeding during labor and delivery

  • Blood in your urine or stool

  • Easy bruising or lumpy bruises

Menstrual signs and symptoms might include:

  • Blood clots greater than 1 inch (2.5 centimeters) in diameter in your menstrual flow

  • The need to change your menstrual pad or tampon more than once an hour

  • The need to use double sanitary protection for menstrual flow

  • Symptoms of anemia, including tiredness, fatigue or shortness of breath

When to see a doctor

Contact your health practitioner when you have bleeding that lasts a long term or is tough to forestall.

Causes Von Willebrand disease(VWD)

The traditional motive of von Willebrand ailment is an inherited bizarre gene that controls von Willebrand issue — a protein that performs a key function in blood clotting.

When you have got low stages of this protein or it doesn't paint because it has to, small blood cells known as platelets can not stick collectively nicely nor connect themselves typically to the blood vessel partitions whilst an harm has passed off. This interferes with the clotting technique and might once in a while cause out of control bleeding.

Many people with von Willebrand disease also have low degrees of element VIII, every other protein that enables clotting.

Factor VIII is concerned in another inherited clotting disease known as hemophilia. But in contrast to hemophilia, which specially affects adult males, von Willebrand disease affects men and women and is commonly milder.

Rarely, von Willebrand sickness can develop later in lifestyles in folks that didn't inherit an affected gene from a figure. This is referred to as acquired von Willebrand syndrome, and it's likely because of an underlying scientific condition.

Von Willebrand disease is a genetic disease that takes place whilst sure genes mutate, or alternate. In von Willebrand ailment, genetic mutations affect your frame’s capability to make regular von Willebrand elements. Factors are proteins that help your blood to clot.

You have von Willebrand to your plasma, platelets and partitions of your blood vessels. Plasma is the liquid part of blood. Platelets are cells that assist blood clot whilst blood vessels rupture from injury or damage.

Normally, platelets stop bleeding with the aid of sticking to damaged blood vessels and assisting to form blood clots. The Von Willebrand issue allows platelets to stick. When you don’t have enough von Willebrand element or you don’t have any issue, your platelets can’t stick as well as they have to and it takes longer for platelets to assist form blood clots.

Most humans have von Willebrand disease because they inherited a mutated gene from one among their organic mother and father. This is autosomal dominant inheritance. Some human beings inherit mutated genes from both organic dad and mom. This is autosomal recessive inheritance and is the maximum severe form of von Willebrand disease. People who bring the mutated gene have a 50% danger of passing the genetic mutation on to their organic kids.

Risk factors Von Willebrand disease(VWD)

The predominant risk issue for von Willebrand sickness is having a family history of it. Parents bypass the gene for the sickness to their kids. Rarely, the disease skips generations.

The disease is usually an "autosomal dominant inherited" disorder, which means you want a mutated gene from the simplest one discerned to get the disease. If you have got the gene for von Willebrand disease, you have a 50% threat of transmitting this gene for your kids.

The maximum excessive form of the condition is "autosomal recessive," because of this both of your mother and father should bypass a mutated gene to you.

People with von Willebrand disease may develop large bruises or bleeding that doesn't stop which can be life-threatening In addition they are at higher risk for other types of bleeding and clotting .

  • Anemia. Heavy menstrual bleeding can cause iron deficiency anemia.

  • Swelling and pain. This can be a result of abnormal bleeding in the joints or soft tissue.

What is the life expectancy of someone with von Willebrand disease?

The life expectancy of a person with von Willebrand disease depends on the severity of the disease Most people with mild cases of this genetic bleeding disorder live into their mid-60s to early 70s People with moderate or severe von Willebrand disease usually have a shorter life expectancy although it varies from one case to another The average lifespan is 2 to 5 years shorter than that of someone who does not have von Willebrand disease.

Can I donate blood with von Willebrand disease?

Almost any medical condition can prevent you from being able to donate blood The best thing to do is contact your local blood bank and ask them directly if you have von Willebrand disease or if you've ever had a problem with your blood clotting Most likely they will want to see your health records first You can also visit the American Red Cross website for more information on eligibility requirements.

Is von Willebrand disease an autoimmune disease?

Von Willebrand disease (vWD) is a rare inherited bleeding disorder It occurs when a protein called von Willebrand factor (vWF) is either not produced or does not function properly The disorder affects about one percent of the population The disorder can be categorized into subtypes depending on how and why it develops but only Type 1 and Type 2 are considered to be autoimmune disorders.

Does von Willebrand disease make you tired?

People with von Willebrand disease tend to have excessive bruising and bleeding Other symptoms include nosebleeds bleeding gums heavy periods easy bruising and frequent cuts and scrapes that do not heal well Women who have von Willebrand disease may experience postpartum hemorrhage after childbirth It also increases your risk of developing blood clots.

Prevention Von Willebrand Disease

Most people inherit von Willebrand disorder. If your biological parents have this circumstance, you can inherit it from one or both of them.

If you plan to have youngsters and have your own family records of von Willebrand disease, recollect genetic counseling. If you bring the gene for von Willebrand disorder, you may skip it in your offspring, even if you don't have signs and symptoms.

Diagnosis Von Willebrand disease(VWD)

To find out if a person has VWD, the medical doctor will ask questions about private and circle of relatives histories of bleeding. The doctor will also take a look at for uncommon bruising or different signs and symptoms of recent bleeding and order some blood exams to measure how the blood clots. The assessments will offer information approximately the quantity of clotting proteins present in the blood and if the clotting proteins are operating properly. Because sure medicines can cause bleeding, even among people without a bleeding ailment, the health practitioner will ask about recent or habitual medicinal drugs taken that would cause bleeding or make bleeding signs and symptoms worse.

Mild kinds of von Willebrand disorder may be difficult to diagnose because bleeding is not unusual, and, for the majority, doesn't imply an ailment. However, in case your medical doctor suspects you have got a bleeding ailment, he or she would possibly refer you to a blood disorders specialist (hematologist).

To compare you for von Willebrand disorder, your physician will probably ask you specific questions on your medical records and test for bruises or other symptoms of new bleeding.

Your doctor may even likely suggest the subsequent blood checks:

  • Von Willebrand factor antigen. This determines the level of the von Willebrand factor for your blood through measuring a specific protein.

  • Von Willebrand factor activity. There are a variety of exams to determine how properly the von Willebrand component works for your clotting system.

  • Factor VIII clotting activity. This shows whether you have abnormally low levels and activity of factor VIII.

  • Von Willebrand factors multimers. This evaluates the shape of the von Willebrand element for your blood, its protein complexes and the way its molecules wreck down. This information allows you to identify the sort of von Willebrand disease you have got.

The outcomes of those checks can range within the same individual over time because of elements which include pressure, workout, contamination, pregnancy and medicinal drugs. So you would possibly need to copy some tests.

  • Replacement therapies. These encompass infusions of focused blood-clotting factors containing von Willebrand issue and factor VIII. Your doctor may endorse them if DDAVP isn't a choice for you or has been useless.
    Another alternative therapy accepted by the Food and Drug Administration for treating adults 18 and older is a genetically engineered (recombinant) von Willebrand thing product. Because recombinant factor is made without plasma, it can lessen the threat of a viral infection or allergy.

  • Oral contraceptives. In addition to stopping pregnancy, those drugs can assist manage heavy bleeding throughout menstrual durations. The estrogen hormones in delivery manage pills can raise von Willebrand factor and issue VIII activity.

  • Clot-stabilizing medications. These antifibrinolytic medicines — such as aminocaproic acid (Amicar) and tranexamic acid (Cyklokapron, Lysteda) — can assist forestall bleeding by slowing the breakdown of blood clots. Doctors often prescribe those drugs before or after a surgical procedure or teeth extraction.

  • Drugs applied to cuts. A fibrin sealant (Tisseel) placed on a cut enables curtail bleeding. This is implemented like glue, the usage of a syringe. There are also over the counter products to forestall nosebleeds.

If your situation is slight, your physician may advocate remedy best whilst you're having surgery or dental work or while you've had a trauma, including a vehicle twist of fate.

Lifestyle and home remedies

Your health practitioner might as a substitute advise pain and fever relievers along with acetaminophen (Tylenol, others).

  • Tell your doctors and dentist. Let your docs or dentist know which you have von Willebrand disorder earlier than you have surgical operation, begin a new remedy or give start. Also point out whether or not all of us for your own family have a history of excessive bleeding.

  • Consider wearing a medical ID bracelet. Make certain it notes that you have von Willebrand sickness, so that it will be beneficial to clinical personnel in case you're in a coincidence or taken to an emergency room. Also deliver a medical alert card for your wallet.

  • Be active and safe. Exercise is part of accomplishing or preserving a healthy weight. Avoid sports that could motivate bruising, inclusive of soccer, wrestling and hockey.
