Acute aplastic anemia, with its rapid onset and short course, may take a patient no more than 1 month from a completely normal blood count to the appearance of severely reduced white blood cells and platelets, which makes it difficult indeed for the family and the patient to react and fall into the abyss of ten thousand feet. The important reason for the seriousness of acute aplastic anemia and the need for emergency hospitalization is its appearance of severe granulocyte deficiency and thrombocytopenia, with the consequent severe uncontrollable infections and bleeding of vital organs, which is like a weak and feeble warrior who has to fend off enemies like a tidal wave for the patient, which is simply impossible. Therefore, the disease is so vicious that it actually wins with speed and efficiency, taking us by surprise, and before we can organize an effective defense, the city has already been sacked. Therefore, the treatment also emphasizes the word “fast”. The treatment is divided into 2 main types of treatment, bone marrow transplantation and anti-thymocyte globulin, and bone marrow transplantation is the better choice for young patients with full-compatibility sibling donors. The effective rate is 50-70%, and the efficiency is further improved with the addition of traditional Chinese medicine. Our and foreign studies have found that the efficiency of treatment within 3 months of the discovery of acute aplastic anemia is significantly higher and patients have a good prognosis. We hope that everyone can establish this principle, early detection and early treatment, and we wish you all good health and happiness.
