aplastic anemia Explained

aplastic anemia at English => English (The Britannica Concise) Of Explained:

Inadequate blood-cell formation by bone marrow. Pancytopenia is lack of all cell types (erythrocytes, leukocytes, and platelets), but any combination may be missing. Drug, chemical, or radiation exposure most often causes the disease, but about half of cases have no known cause. It may occur at any age. Acute disease may be quickly severe, even fatal; chronic disease has symptoms incl. weakness, shortness of breath, headache, fever, and pounding heart. There is usually a waxy pallor. Hemorrhages occur in mucous membranes, skin, and other organs. Lack of white blood cells lowers resistance to infection and becomes the major cause of death. Very low platelet count may lead to severe bleeding. The treatment of choice is bone-marrow transplantation. Otherwise, treatment involves avoiding any known toxic agent, and giving fluids, glucose, and proteins (often intravenously) as well as blood components and antibiotics.
