Brothers Healthcare is committed to serving the bleeding disorders community. We recognize that the needs and experiences of VWD patients are different from someone with hemophilia or another bleeding disorder. That’s why our commitment is to provide you with relevant VWD resources, targeted education, and meaningful support networks. At Brothers Healthcare, we know the importance of connection because many of us are on this journey with you.
Von Willebrand Disease (VWD) is the most common inherited bleeding disorder, much more prevalent than hemophilia or any other bleeding disorder. According to the Centers for Disease Control and Prevention, “VWD occurs with equal frequency among men and women, affecting up to 1% of the general population” (Nov. 17, 2016).
While Hemophilia A or B affect the quantity of clotting Factor VIII (8) or Factor IX (9) in the body, Von Willebrand Disease affects the quantity and/or quality of the Von Willebrand Factor (VWF). The purpose of the VWF is first to provide a bridge between the platelets and the bleed site and second to protect Factor VIII in the blood (learn more). There are three types of VWD and each type can vary in severity.
Type 1 – Lower quantity of VWD protein, 50-80% of normal. Mostly mild bleeding, although severe bleeds can happen. Type 1 VWD is most common. Approx. 75% of VWD patients have Type 1.
Type 2- The quality of VWD protein is affected as the proteins are not properly formed. There are 4 subtypes connected to which sections of the protein is mis-formed. Symptoms tend to be mild to moderate. About 20% of VWD patients have Type 2.
Type 3- Very low quantity of VWD, which also leads to very low levels of Factor VIII. Replacement of both proteins may be required for treatment.
Bleeding tends to be severe. This type affects about 5% of VWD patients (hemophilia.org).
