Can a dog with von Willebrand factor be given DDAVP?

Some dogs with vWD are able to increase the amount of von Willebrand factor in circulation after the administration of DDAVP, although the response is variable. At this time, it is not recommended to use this drug on a regular basis.

What is von Willebrand disease in dogs?

Von Willebrand’s disease (vWD) is the most common inherited bleeding disorder of both humans and dogs. It is caused by a deficiency in the amount of a specific protein needed to help platelets (the blood cells used in clotting) stick together and form clots to seal broken blood vessels.

Is von Willebrand a form of hemophilia?

Von Willebrand disease is a distinct disorder, it is not hemophilia. There are three variants or forms of vWD (types 1,2,3) defined by the quantity and structure of plasma von Willebrand factor (abbreviated vWF) in affected dogs. Within each breed a single form of vWD predominates.

  • Von Willebrand factor antigen. This determines the level of von Willebrand factor in your blood by measuring a particular protein.
  • Von Willebrand factor activity. There are a variety of tests to measure how well the von Willebrand factor works in your clotting process.
  • Factor VIII clotting activity.
  • Von Willebrand factor multimers.

How is von Willebrand disease diagnosed?

What is the prognosis for von Willebrand disease?

When there is a decrease in plasma levels or defect in the von Willebrand factor, the ability of the blood to clot decreases leading to a heavy and continuous bleeding after an injury which is termed as von Willebrand disorder or disease (VWD). This may cause internal organ damage and rarely may lead to death[1].

Is von Willebrand disease serious?

Women with VWD are at increased risk of excessive bleeding during and after childbirth, which may result in severe anemia, require transfusion or even develop into life-threatening blood loss. Even with VWD-specific treatment, women with VWD have relatively high rates of postpartum hemorrhage.

Which breeds are most commonly affected by von Willebrand factor?

The deficient protein is called von Willebrand factor (vWF). Which breeds are most commonly affected by vWD? At least thirty different breeds are affected, but the Doberman Pinscher is the breed with the highest incidence of vWD. Of 15,000 Dobermans screened in a research study, more than 70% were found to be carriers of the disease.

What is von Willebrand’s disease in dogs?

There’s a name for this: von Willebrand’s disease (vWD), which is a disorder in dogs that is characterized by excessive bleeding due to a defect in platelet function. VWD is a hereditary disease that is passed from parents to pup in a rather complicated way.

How common is vWD in Doberman Pinschers?

At least thirty different breeds are affected, but the Doberman Pinscher is the breed with the highest incidence of vWD. Of 15,000 Dobermans screened in a research study, more than 70% were found to be carriers of the disease. Fortunately, most of these were not showing signs of the disease at the time of testing.

Can dogs with von Willebrand disease donate blood?

The dog donating blood may be treated with a drug called DDAVP prior to blood collection. DDAVP will raise the level of von Willebrand factor in the donor’s blood, an obvious benefit for the dog with vWD.

Can You give Dogs aspirin for von Willebrand disease?

Affected dogs should not be given drugs that interfere with normal blood clotting mechanisms. These drugs include aspirin, sulfa-type antibiotics, and heparin. Laboratory diagnosis of vWD is most often based on results of von Willebrand factor antigen assay (abbreviated vWF:Ag).

How much does DDAVP increase CBA in dogs?

In control dogs, mean plasma vWF:Ag and vWF:CBA increased from baseline values of 64% to 113% and 58% to 114%, respectively, and the vWF Ag:CBA ratios were unchanged (1.1 vs 1.0) after DDAVP administration.

How does DDAVP affect blood glucose levels in dogs with Type 1 vWD?

Results: Following DDAVP administration, dogs with type 1 vWD had an increase in mean baseline values of plasma vWF:Ag and vWF:CBA from 10% to 17% for both variables. The mean vWF Ag:CBA ratio at baseline (0.95) was similar after DDAVP administration (0.97), indicating concordant increases in plasma vWF concentration and activity.
