Qualitative Platelet Disorders in Children – When Platelet Count Is Normal but Bleeding Persists

Most parents associate “bleeding problems” with low platelet counts. But what if your child’s platelet count is normal, and they still experience frequent nosebleeds, gum bleeding, or excessive bruising?

In such cases, the issue might not be the quantity of platelets — but their quality.
This condition is known as a Qualitative Platelet Disorder, meaning the platelets are present in normal numbers but do not function properly.

As a Pediatric Hematologist, I see many such cases where children appear completely healthy, but their platelets fail to perform their clotting role efficiently.

✅ Inherited (Congenital) Disorders:
These are rare but often present early in childhood.
Common examples include:

• Glanzmann Thrombasthenia – Defect in platelet aggregation.

• Bernard-Soulier Syndrome – Defect in platelet adhesion; platelets are abnormally large.

• Storage Pool Disease – Platelets lack essential granules that release clot-promoting substances.

✅ Acquired Disorders:
Develop later in life due to:

• Certain drugs (aspirin, NSAIDs, antibiotics)

• Uremia (kidney disease)

• Bone marrow disorders

• Autoimmune diseases
  

Symptoms of platelet dysfunction can range from mild to severe:

• Frequent nosebleeds (epistaxis)

• Easy bruising, even without injury

• Bleeding gums after brushing or dental work

• Prolonged bleeding from small cuts or injuries

• Excessive bleeding after surgery, vaccination, or tooth extraction

• Prolonged menstrual bleeding in adolescent girls

Parents often confuse these symptoms with vitamin deficiencies — but persistent bleeding warrants evaluation by a hematologist.

Diagnosis requires specialized testing, since the platelet count is usually normal.

Common investigations include:

• Complete Blood Count (CBC): To confirm platelet quantity is normal.

• Peripheral Smear: To assess platelet size and appearance.

• Platelet Function Tests (Aggregation & Secretion Studies): To evaluate how well platelets respond to stimuli.

• Flow Cytometry: To identify missing surface receptors in specific disorders.

• Genetic Testing: For inherited platelet dysfunction syndromes.

Accurate diagnosis is crucial, as treatment varies significantly between conditions.

Treatment depends on the severity and cause of the disorder:

✅ For Mild Cases:

• Avoid medications like aspirin or ibuprofen that worsen platelet function.

• Iron supplementation may help compensate for chronic blood loss.

✅ For Moderate to Severe Cases:

• Platelet Transfusions: Used during surgeries or major bleeding episodes.

• Antifibrinolytic Medicines (Tranexamic Acid): Reduce bleeding from gums, nose, or menstruation.

• Desmopressin (DDAVP): Stimulates temporary release of clotting factors in certain conditions.

• Recombinant Factor VIIa: Used in severe inherited disorders like Glanzmann Thrombasthenia.

✅ For Genetic Conditions:

• Long-term follow-up under a Pediatric Hematologist is essential.

• Genetic counseling for families may be advised.

• Inform teachers and caregivers about the child’s condition.

• Avoid contact sports or activities with a risk of injury.

• Always inform doctors or dentists before any surgery or dental work.

Maintain a bleeding diary to track frequency and duration of episodes.

With early diagnosis and proper management, most children with qualitative platelet disorders lead normal, active lives.
Modern therapies and targeted treatments have significantly improved quality of life and reduced bleeding risks.

When a child continues to bleed despite a normal platelet count, it’s not “just a phase” — it could be a platelet function disorder that requires specialized care.

With expert evaluation, supportive therapies, and awareness, these children can grow up safely and confidently.

If your child has unexplained or prolonged bleeding, consult a Pediatric Hemato-Oncologist for accurate diagnosis and comprehensive management.
