What are the causes of prolonged bleeding episodes?

Question

Hello doctor,

My niece, who has no prior diagnosis, has been experiencing frequent nosebleeds and easy bruising over the past year. Recently, she had prolonged bleeding after a minor cut. There is no reported family history of bleeding disorders. The patient's symptoms are suggestive of a bleeding disorder, but the absence of a family history raises questions about a diagnosis of hemophilia.

What diagnostic tests should be prioritized to confirm or rule out hemophilia?
Could other conditions, such as von Willebrand disease or platelet function disorders, be contributing to these symptoms?
Additionally, what precautions should be taken to manage bleeding episodes effectively while awaiting a definitive diagnosis?

Please help.

Thank you.

Hello,

Welcome to icliniq.com.

I understand your concern.

Bleeding disorders like hemophilia, von Willebrand disease (vWD), and platelet function disorders can manifest with frequent nosebleeds, easy bruising, and prolonged bleeding, even in the absence of a family history.

I suggest she undergo the following tests:

Complete blood count (CBC): To check for thrombocytopenia, which can cause bleeding.
Peripheral blood smear: To evaluate the size, shape, and appearance of platelets, helping identify platelet disorders.
Prothrombin time (PT) and activated partial thromboplastin time (aPTT): To assess the blood's clotting ability and screen for coagulation disorders.
Hemophilia A Factor VIII and IX levels: Essential for confirming hemophilia A (factor VIII deficiency) or hemophilia B (factor IX deficiency). If levels are normal, hemophilia can be ruled out.
Von Willebrand factor antigen: To investigate the possibility of von Willebrand disease.
Platelet function tests: To assess platelet activity.
Thrombin time (TT): To evaluate clot formation and detect fibrinogen abnormalities.

The following conditions must be ruled out:

Hemophilia.
Von Willebrand disease.
Platelet function disorders (for example, Glanzmann’s thrombasthenia and Bernard-Soulier syndrome).
Immune thrombocytopenia (ITP).
Deficiencies in clotting factors II, V, VII, or X.
Anticoagulant use (though unlikely in children).

Management includes:

Minimize trauma: Avoid contact sports or activities that may cause injury or cuts.
For nosebleeds: Pinch the nose firmly and tilt the head slightly forward. Use a cold compress to reduce bleeding.
For cuts: Apply firm pressure to stop bleeding.
Medication precautions: Avoid aspirin or NSAIDs (nonsteroidal anti-inflammatory drugs), as they can worsen bleeding.
Anemia: If there is evidence of anemia due to chronic blood loss, iron supplementation may be needed.

Further management will depend on the diagnosis:

Hemophilia: Replacement therapy with the deficient clotting factor.
Von Willebrand disease (vWD): Desmopressin (DDAVP) for mild cases and vWF concentrates for more severe cases.
Platelet function disorders: Platelet transfusions as needed.

A physical examination and evaluation by a hematologist in a hospital is essential.

Get well soon.

Hope I answered the question.
