Could extra white cells boost immune recovery in kids with tough leukemia?

This study looks at whether giving children with hard-to-cure leukemia a transfusion of white blood cells (granulocytes) after a cord blood transplant helps their new immune system grow faster and safer. About 40 children under 16 will receive this extra transfusion, and researchers will check for side effects like cytokine release syndrome and whether the treatment helps control leukemia without causing graft-versus-host disease. The goal is to improve recovery and reduce complications in kids who need a transplant.
