Aplastic anemia [2] (AA) [3] is a severe hematologic condition in which the body fails to make blood cells in sufficient numbers. Blood cells are produced in the bone marrow by stem cells that reside there. [4] Aplastic anemia causes a deficiency of all blood cell types: red blood cells, white blood cells, and platelets. [5] [6]
Pure red cell aplasia (PRCA) or erythroblastopenia refers to a type of aplastic anemia affecting the precursors to red blood cells but usually not to white blood cells. In PRCA, the bone marrow ceases to produce red blood cells. There are multiple etiologies that can cause PRCA. The condition has been first described by Paul Kaznelson in 1922. [1]
The global market for anemia treatments is estimated at more than USD 23 billion per year and is fast growing because of the rising prevalence and awareness of anemia. The types of anemia treated with drugs are iron-deficiency anemia, thalassemia, aplastic anemia, hemolytic anemia, sickle cell anemia, and pernicious anemia, the most important ...
Red blood cells normally survive an average of about 120 days, becoming damaged (their oxygen-carrying capacity becomes compromised) as they age.
It is characterized by anemia and reticulocytopenia and can be chronic or acute. [3] Diamond–Blackfan anemia is a type of PRCA that occurs at birth. PRCA can be acquired as a primary disorder or as a result of another disorder. [4] Immunosuppressive drugs, particularly corticosteroids, will usually result in a temporary or permanent remission.
Anemia of prematurity is a form of anemia affecting preterm infants [25] with decreased hematocrit. [26] Aplastic anemia: D60-D61: 866: Aplastic anemia is a condition where bone marrow does not produce sufficient new cells to replenish blood cells. [27] Autoimmune hemolytic anemia: D59.0-D59.1
Why the meat you eat affects your brain. The connection between red meat and cognitive health hasn’t been studied thoroughly, but researchers have found associations with many other health ...
With isolated reticulocytopenia, the main cause is Parvovirus B19 infection of reticulocytes leading to transient anemia. [2] In patients who rely on frequent red cell regeneration e.g. sickle cell disease, a reticulocytopenia can lead to a severe anemia due to the cessation in red cell production (erythropoiesis), referred to as aplastic ...
