Myelodysplastic syndrome (MDS) is a form of blood cancer in which the bone marrow no longer produces enough healthy, normal blood cells. [9] MDS are a frequently unrecognized and rare group of bone marrow failure disorders, yet the incidence rate has rose from 143 reported cases in 1973 to approximately 15,000 cases in the United States each year.
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]
Pancytopenia – when all three types of blood cells; red blood cells, white blood cells, and platelets, are all deficient. 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.
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.
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
Paroxysmal nocturnal hemoglobinuria (rare acquired clonal disorder of red blood cell surface proteins) Direct physical damage to RBCs Microangiopathic hemolytic anemia; Secondary to artificial heart valve(s) Aplastic anemia. Fanconi anemia; Diamond–Blackfan anemia (inherited pure red cell aplasia) Acquired pure red cell aplasia; Decreased ...
An analysis of data from more than 8,000 adults in the U.S. revealed that 14 ... red blood cells due to low levels of iron — in routine blood tests, people can have enough red blood cells but ...
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]
