CGD is treated with various measures aimed at making up for the deficiencies of the innate immune system. Long-term treatments include the following antibiotic therapy (to help stave off bacteria) and interferon, a substance that helps activate the immune system. Severe acute infections may be treated by transfusions of healthy white blood cells from blood donors. Because the white blood cells involved in CGD are part of the innate immune system, which is not specific, these cells work just as well in the recipient's body as in the donor's body. Bone marrow transplants may be considered because marrow from healthy donors contains blood stem cells that produce normal white blood cells.
