Patients with aplastic anemia generally have normal liver and kidney functions. However, in certain special circumstances, abnormalities in liver and kidney functions may occur, including: Firstly, the routine treatment for aplastic anemia mainly includes the immunosuppressant cyclosporine and the hematopoietic stimulant androgens. The primary side effect of cyclosporine is renal toxicity. Therefore, during the use of cyclosporine, it is necessary to monitor the concentration of cyclosporine; excessive levels can lead to renal dysfunction. Androgens, including stanozolol and danazol, primarily cause hepatic toxicity; hence, it is necessary to monitor liver and kidney functions during treatment of aplastic anemia. The second factor that may cause liver and kidney function abnormalities is severe anemia. Long-term severe anemia can lead to tissue ischemia and hypoxia in the liver or kidneys, and if prolonged, it can cause abnormalities in liver and kidney functions. (Medication use should be carried out under the guidance of a physician.)
