Aplastic anemia is a bone marrow failure disease caused by various factors. Depending on the severity of the condition, it can be classified into chronic aplastic anemia and acute aplastic anemia, which differ in treatment methods and survival rates. Chronic aplastic anemia is typically treated with androgen-based medications such as testosterone propionate, Andriol, and danazol. Most patients with chronic aplastic anemia achieve high remission rates after active treatment and can survive for more than a decade. Only a very small percentage of chronic aplastic anemia patients may progress to acute aplastic anemia. Acute aplastic anemia can be managed with symptomatic supportive treatment or immunosuppressive therapy. More than half of the patients with acute aplastic anemia achieve remission, but nearly one-third of these patients may die within a year.
