Aplastic anemia: history and recent developments in diagnosis and treatment

Acquired aplastic anemia aplastic anemia: (ay-PLASS-tik uh-NEE_mee-uh) A rare and serious condition in which the bone marrow fails to make enough blood cells - red blood cells, white blood cells, and platelets. The term aplastic is a Greek word meaning not to form. Anemia is a condition that happens when red blood cell count is low. Most… is an immune-mediated disease that targets hematopoietic stem cells stem cells: Cells in the body that develop into other cells. There are two main sources of stem cells. Embryonic stem cells come from human embryos and are used in medical research. Adult stem cells in the body repair and maintain the organ or tissue in which they are found. Blood-forming (hemapoietic) stem… , which is diagnosed by findings of peripheral blood pancytopenia pancytopenia: A shortage of all types of blood cells - red blood cells, white blood cells, and platelets. and hypocellular hypocellular: A condition in which there are too few cells, for example, within the bone marrow. Patients with aplastic anemia have hypocellular bone marrow. bone marrow bone marrow: The soft, spongy tissue inside most bones. Blood cells are formed in the bone marrow. . Although the diagnostic definition is simple, differential diagnosis from other overlapping hematopoietic disorders such as hypoplastic myelodysplastic syndrome and inherited bone marrow failure bone marrow failure: A condition that occurs when the bone marrow stops making enough healthy blood cells. The most common of these rare diseases are aplastic anemia, myelodysplastic syndromes (MDS) and paroxysmal nocturnal hemoglobinuria (PNH). Bone marrow failure can be acquired (begin any time in life) or can be… syndrome is not easy. Immune suppressive therapy and allogeneic hematopoietic stem cell transplantation are important treatment approaches for aplastic anemia, and both have advanced in recent years. This issue of Progress in Hematology covers four topics related to aplastic anemia: (1) laboratory markers to identify immune pathophysiology pathophysiology: Functional changes in the bodies that are associated with or result from disease or injury. and their role on differential diagnosis and prognosis, (2) the path to combination therapy with horse anti-thymocyte globulin, cyclosporine cyclosporine: Cyclosporine is used along with antithymocyte globulin (ATG), another immunosuppressant, for treating aplastic anemia and some other forms of bone marrow failure. A, and eltrombopag eltrombopag: What are the possible side effects of eltrombopag (Promacta)? Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat. Stop using eltrombopag and call your doctor at once if you have: … , (3) more than 60 years of history and recent trends in allogeneic HSCT, and (4) genetic testing for differential diagnosis from IBMFS and novel approaches to transplantation for children including fludarabine fludarabine: The U.S. Food and Drug Administration (FDA) approved fludarabine for treating chronic lymphocytic leukemia (CCL). Researchers are studying fludarabine in combination with other medicines for treating bone marrow failure. /melphalan-based conditioning.
