Can patients with epilepsy become bone marrow donors? A case report of allogeneic hematopoietic stem transplantation from child with seizures

Hematopoietic stem cell (HSC) transplantation is an important treatment option for malignant and non-malignant hematopoietic disorder in adults and children. For long time epilepsy was temporary exclusion condition to voluntary donation, and donors had to be medication or seizure free. It is still unclear if people with history of epilepsy are indeed potential eligible donors, even if a significant increased risk of adverse events in these donors has not been demonstrated. We studied a 10-year-old boy with symptomatic focal epilepsy who was the only available donor for his monozycote twin, suffering from acute lymphoblastic leukemia. A total of 3.39 x 108/kg HSCs were collected and reinfused to the leukemic brother after conditioning treatment. At the end of follow-up, our epilepsy patient had no consequences and his brother is in complete remission of the disease at 3 years from the transplant procedure. Our observation confirms that a patient with epilepsy can be a donor, without consequences for himself and for the recipient.
