In aplastic anemia, the marrow failure causes pancytopenia, so stopping an offending agent is an important initial step, but the treatment that can truly cure the disease is replacing the defective hematopoietic system with a healthy donor. A bone marrow transplant introduces donor stem cells that reconstitute all blood cell lines and can restore normal marrow function, making it the most definitive therapy, especially in younger patients with a matched donor. If a transplant isn’t possible, immunosuppressive therapy may improve counts but isn’t curative in many cases, whereas the other options are supportive or address different issues rather than the root marrow failure. Platelet transfusions provide temporary bleeding control, iron chelation handles iron overload from transfusions, and splenectomy doesn’t address the underlying marrow failure.
