My son has hemophilia A. What activities are safe for him?

Question

Hello doctor,

My 9-year-old son was recently diagnosed with mild hemophilia A after experiencing repeated bruising and a prolonged aPTT (activated partial thromboplastin time) of 52 seconds. His factor VIII activity was measured at 8 %. While the hematologist recommended Desmopressin before procedures, I am still quite anxious and have a few concerns:

How safe is it for him to participate in regular activities like biking or soccer?
Do we need to avoid routine vaccinations or dental cleanings?
Is there any chance that his factor VIII levels could improve with age or treatment?
What signs should we watch for that may indicate internal bleeding?
Should his school be informed of his condition, and should there be an emergency care plan in place?

Kindly suggest.

Hello,

Welcome to icliniq.com.

I understand your concern.

Mild hemophilia A, with a factor VIII level of 8 %, generally allows for a fairly normal lifestyle with appropriate precautions. Desmopressin (1-deamino-8-D-arginine vasopressin) (DDAVP) is effective in many mild cases and can temporarily raise factor VIII levels before procedures or following injuries.

Regular activities like biking or soccer are typically safe with protective gear and close supervision, though high-contact sports such as football or wrestling should be approached with caution.

Vaccinations and routine dental cleanings are not contraindicated, but it is essential to inform the provider in advance. Using a small-gauge needle and applying prolonged pressure afterwards can help minimize bleeding. While factor VIII levels typically do not increase with age, symptoms can be well managed with proper treatment.

Signs of internal bleeding to watch for include:

Unexplained joint pain or swelling.

Headaches.
Vomiting.
Lethargy (may signal a brain bleed).
Blood in urine or stool.

The school must be informed of the diagnosis. A written care plan should be in place, including emergency contacts and clear instructions on how to respond to a bleeding episode, such as when to administer Desmopressin or call emergency services. This ensures your child remains safe, understood, and supported during school hours.

I hope this information helps you.

Thank you.
