Understanding Bleeding Disorders: Hemophilia A, Hemophilia B, Von Willebrand Disease, and More

Bleeding disorders affect the body’s ability to form stable blood clots, which can lead to prolonged or spontaneous bleeding. While some are inherited, others may develop later in life. For healthcare professionals, especially nurses, understanding the nature of these disorders is vital for safe patient care, especially when managing medications, invasive procedures, or injuries. This blog post reviews key inherited bleeding disorders—Factor VIII deficiency, Factor IX deficiency, and Von Willebrand disease—as well as less common, minor bleeding disorders.

Factor VIII Deficiency (Hemophilia A)

Hemophilia A is the most common severe inherited bleeding disorder, caused by a deficiency or absence of clotting Factor VIII. It is an X-linked recessive disorder, primarily affecting males, while females are typically carriers.

Signs and Symptoms:

  • Easy bruising
  • Prolonged bleeding after injury or surgery
  • Spontaneous joint bleeds (hemarthrosis)
  • Deep muscle bleeding

Management:

  • Intravenous replacement of Factor VIII concentrates
  • Preventative (prophylactic) factor therapy
  • Desmopressin (DDAVP) may be used for mild cases

Factor IX Deficiency (Hemophilia B)

Also known as Christmas Disease, Hemophilia B results from a deficiency of Factor IX and shares many clinical characteristics with Hemophilia A. It is likewise X-linked and predominantly affects males.

Signs and Symptoms:

  • Similar to Hemophilia A
  • Frequent nosebleeds
  • Hematuria (blood in urine)

Management:

  • Factor IX replacement therapy
  • Regular prophylaxis for patients with severe disease

Von Willebrand Disease (vWD)

Von Willebrand Disease is the most common inherited bleeding disorder and affects both men and women. It is caused by a deficiency or dysfunction of von Willebrand factor (vWF), a protein crucial for platelet adhesion and stabilization of Factor VIII.

Types:

  • Type 1: Partial quantitative deficiency of vWF (mild to moderate symptoms)
  • Type 2: Qualitative defects in vWF (moderate to severe symptoms)
  • Type 3: Near-complete absence of vWF (rare, severe symptoms)

Signs and Symptoms:

  • Frequent nosebleeds
  • Heavy or prolonged menstrual bleeding
  • Easy bruising
  • Bleeding after dental work or surgery

Management:

  • Desmopressin (DDAVP) for Type 1 and some Type 2 cases
  • vWF-containing Factor VIII concentrates for more severe types
  • Antifibrinolytic agents like tranexamic acid

Other Minor Bleeding Disorders

Several less common inherited or acquired bleeding disorders may also affect patients:

Platelet Function Disorders:

  • Glanzmann thrombasthenia
  • Bernard-Soulier syndrome
  • Storage pool diseases

Factor Deficiencies:

  • Factor I (fibrinogen) deficiency
  • Factor II (prothrombin) deficiency
  • Factor V, VII, X, XI, and XIII deficiencies

Acquired Disorders:

  • Liver disease-induced coagulopathies
  • Vitamin K deficiency
  • Disseminated intravascular coagulation (DIC)
  • Medication-induced bleeding (e.g., anticoagulants, antiplatelets)

Though rare, these disorders can complicate medical care and must be identified and managed appropriately.
