The first is to apply a combination of treatments, including immunosuppressants, cytokines, blood transfusions and stimulation of bone marrow hematopoiesis. This treatment usually takes effect about 4 months after treatment. The second is bone marrow transplantation. A suitable donor is required. The main problems are rejection and implantation.
