Will stem cell therapy work for treating CATP in children?

Question

Hello doctor,

My nephew has recently been diagnosed with congenital amegakaryocytic thrombocytopenia (CAMT). It has been very overwhelming, and his platelet counts remain very low consistently. One doctor told us that stem cell therapy might be the only curative treatment.

However, we are confused about whether it truly cures the condition or just manages the symptoms over the long term. We are also concerned about how difficult it is to find a match for stem cell donation and whether there are risks associated with undergoing this procedure at such a young age.

We are worried about potential infections during the procedure. Is this therapy commonly used for CAMT now, and what are the chances it will work for him without relapse?

Kindly help.

Thank you.

Hello,

Welcome to icliniq.com.

I can understand your concern.

Congenital amegakaryocytic thrombocytopenia (CAMT) is a rare, inherited bone marrow failure syndrome. Treatment options for congenital amegakaryocytic thrombocytopenia include blood transfusions and stem cell transplant, which is the only curative treatment for CAMT.

The main treatment is allogeneic hematopoietic stem cell transplant (HSCT), a procedure in which stem cells are used to produce different types of blood cells. These stem cells can come from genetically similar donors, though not necessarily identical twins. HSCT can serve as a potential cure for CAMT. Doctors generally consider this treatment as early as possible, usually before the child turns three years old.

However, complications from HSCT can be fatal in up to twenty percent of cases. The highest risk of relapse occurs in the early stages following the transplant, but this risk decreases after about two years. It is much rarer to experience a relapse after five years, but it is still possible. Your medical team will closely monitor for any signs of relapse during regular follow-up check-ups.

I hope this helps.

Take care.
