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]
Red blood cells normally survive an average of about 120 days, becoming damaged (their oxygen-carrying capacity becomes compromised) as they age.

This is a list of mnemonics used in medicine and medical science, categorized and alphabetized. A mnemonic is any technique that assists the human memory with information retention or retrieval by making abstract or impersonal information more accessible and meaningful, and therefore easier to remember; many of them are acronyms or initialisms which reduce a lengthy set of terms to a single ...
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]
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 ...
This is a life-threatening disorder that is a characteristic of aplastic anemia. [3] There are also two general causes of cytopenia: autoimmune and refractory. Autoimmune cytopenia is caused by an autoimmune disease when your body produces antibodies to destroy the healthy blood cells.
Aplastic anemia patients present with symptoms related to a decrease in hematopoietic cell production in the bone marrow. The onset is gradual, and the first symptom is frequently anemia or bleeding, though a high temperature or infections may be present at the onset. The following are examples of specific manifestations: [12]
