The majority of patients with severe aplastic anemia can be cured, but there are some refractory patients whose lives may be endangered due to exacerbation of the disease. 1. The current treatments for severe aplastic anemia include immunosuppressant therapy and bone marrow transplantation. Immunosuppressant therapy, such as anti-lymphocyte globulin and anti-thymocyte globulin, can help most of the patients to achieve remission of the disease, but the general treatment time is relatively long, and the gradual recovery of various indicators of the blood count is usually achieved in about three months. 2. Bone marrow transplantation, through the transplantation of hematopoietic stem cells from the bone marrow of a healthy donor into the patient’s body, so that the patient’s bone marrow hematopoietic function is restored and the number of blood cells in the body is gradually restored, most of which can be cured. However, due to the severity of the disease, patients with severe aplastic anemia are susceptible to life-threatening infections, bleeding, etc. Not all patients can be cured through treatment. Patients with severe aplastic anemia should go to regular hospitals in time, and doctors should determine the specific treatment method according to the patient’s condition, so that the patient can recover as soon as possible through correct treatment.
