Untreated, severe aplastic anemia has a high risk of death. [36] Modern treatment produces a five-year survival rate that exceeds 85%, with younger age associated with higher survival. [37] Survival rates for stem cell transplants vary depending on the age and availability of a well-matched donor.
In Europe and North America, the incidence of acquired aplastic anemia is rare with two episodes per million people each year, yet in Asia rises with 3.9 to 7.4 episodes per million people each year. [15] While acquired aplastic anemia with an unknown cause is rare, it is commonly permanent and life-threatening as half of those with this ...
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]
Fanconi anemia (FA) is a rare, ... (MDS), and liver tumors. 90% develop aplastic anemia (the inability to produce blood cells) ... two-year survival rates drop to 54%.
In the 1990s, Young initiated and implemented a formal epidemiologic study of aplastic anemia in Thailand, which revealed a much higher incidence rate than in the West. [5] Coincidentally, he established a teaching program an NHLBI-sponsored teaching program in Vietnam, for which he later received a Government of Vietnam Service to the People ...
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 ...
