Immunosuppressive therapy (IST) can be used when patient has a diagnosis of aplastic anemia. What is the relationship between this treatment and a prevalent theory on pathophysiology of the disorder? (Objectives 1, 3)
A) Current theory holds that the cause of AA is due to hematopoietic stem cells suppression by abnormal cytotoxic T lymphocytes, which are sensitive to IST.
B) Current theory is that AA is due to neoplastic changes in hematopoietic stem cells, which must be eliminated by IST.
C) Because current theory emphasizes the role of environmental factors such as toxin and drug exposure, IST enhances immune function and helps the individual with AA mount an immune response.
D) There is no evidence of a relationship between the cause of AA and IST; we know only empirically that it is effective.
