Retroviruses, or aplastic anemia, are generally difficult to cure by simply taking cyclosporine, and need to be used in conjunction with other medications for specialist treatment. 1. Aplastic anemia is a bone marrow hematopoietic failure caused by a variety of reasons, with a decrease in whole blood cells as the main manifestation. Some people with aplastic anemia can improve their blood picture after taking cyclosporine for 3-6 months. After hematological remission is achieved, cyclosporine needs to be maintained in small doses for a long period of time to help reduce recurrence, but it is generally difficult to achieve a cure. 2. Clinically, cyclosporine, anti-thymocyte globulin and androgenic drugs (testosterone undecanoate) are generally used in combination in order to achieve more satisfactory therapeutic effects. In addition, severe aplastic anemia requires bone marrow transplantation to re-establish hematopoietic function, but there is still a risk of relapse. When suffering from aplastic anemia, you should standardize the treatment and adhere to the medication under the guidance of your doctor so as not to affect your condition.
