Von Willebrand Disease (VWD) is the most common inherited bleeding disorder, characterized by a deficiency or dysfunction of von Willebrand factor (VWF), a glycoprotein essential for platelet adhesion and aggregation. Children with VWD often present with mucocutaneous bleeding, such as frequent nosebleeds, easy bruising, heavy menstrual bleeding, and bleeding from cuts. Severity varies based on the type of VWD, which includes Type 1 (partial quantitative deficiency), Type 2 (qualitative defects), and Type 3 (virtual absence of VWF) (Rodgers & Bissonnette, 2020).

Two primary differential diagnoses for VWD are Hemophilia A and Platelet Function Disorders. Hemophilia A, an X-linked recessive disorder due to clotting factor VIII deficiency, presents with similar bleeding tendencies but is distinguished by prolonged activated partial thromboplastin time (aPTT). Children may experience deep tissue bleeding, hemarthroses, and spontaneous bleeding episodes (Khair et al., 2020).

Platelet Function Disorders (PFDs) encompass a variety of inherited or acquired conditions where platelets exhibit abnormal adhesion, aggregation, or secretion. Children with PFD often demonstrate mucocutaneous bleeding like VWD but show normal levels of VWF and clotting factors. Symptoms include easy bruising, petechiae, nosebleeds, and bleeding after surgical procedures (Liu et al., 2019). These disorders can be differentiated from VWD through specialized platelet function testing results.

For children diagnosed with VWD, treatment strategies depend on the severity and type. Desmopressin (DDAVP) is effective in Type 1 VWD, as it stimulates the release of stored VWF from endothelial cells, reducing bleeding episodes (Laffan & O'Connell, 2018). In cases of Type 2 and Type 3 VWD, or when DDAVP is ineffective, replacement therapy with plasma-derived VWF concentrates is indicated. Antifibrinolytics, such as tranexamic acid or aminocaproic acid, are used adjunctively for mucosal bleeding or dental procedures. Education on bleeding management, avoiding contact sports, and regular monitoring are vital components of care for pediatric patients (Rodgers & Bissonnette, 2020).

Von Willebrand Disease (VWD) is a common inherited bleeding disorder characterized by deficient or defective von Willebrand factor (VWF), essential for platelet adhesion and stabilization of factor VIII. Children with VWD often exhibit mucocutaneous bleeding such as epistaxis, gingival bleeding, easy bruising, and menorrhagia. The disease's presentation varies according to the type and severity, ranging from mild mucocutaneous bleeding to severe hemorrhages (Favaloro et al., 2018). Early diagnosis and treatment are vital to managing bleeding episodes and improving quality of life in pediatric patients.

In differential diagnosis, Hemophilia A and Platelet Function Disorders (PFDs) are primary considerations. Hemophilia A, caused by deficiencies in factor VIII, presents with bleeding features similar to VWD but typically involves deep tissue bleeding, ultrasonographic evidence of hemarthroses, and prolongation of activated partial thromboplastin time (aPTT). This disorder is inherited in an X-linked pattern, primarily impacting males, and requires specific factor VIII replacement therapy (Nemours Foundation, 2020). Differentiating from VWD involves comprehensive coagulation testing, including measurements of factor VIII activity and VWF levels.

PFDs constitute a group of inherited or acquired conditions where platelets cannot adequately adhere or aggregate, leading to mucocutaneous bleeding. These disorders often mimic VWD but are characterized by normal VWF and clotting factor levels. Laboratory assessment, particularly platelet aggregation studies, is essential for diagnosis. PFDs are differentiated from VWD through specialized tests that evaluate platelet function, such as light transmission aggregometry (Favaloro et al., 2018).

Management of VWD in children involves various therapies depending on disease subtype and bleeding severity. Desmopressin (DDAVP), a synthetic vasopressin analogue, stimulates endothelial release of VWF and factor VIII, and is effective primarily in Type 1 VWD. It is administered as a nasal spray or infusion prior to procedures or bleeding episodes (O'Connell et al., 2017). For types 2 and 3, or when DDAVP is ineffective, plasma-derived VWF concentrates are administered intravenously, effectively elevating VWF and factor VIII levels. Adjunctive measures include antifibrinolytics such as tranexamic acid, used to control mucosal bleeding or during dental procedures (Laffan & O'Connell, 2018). Patient education, avoidance of trauma, and regular hematologic monitoring are crucial components of comprehensive care.
