  2. Aplastic anemia - Wikipedia

    en.wikipedia.org/wiki/Aplastic_anemia

    Aplastic anemia causes a deficiency of all blood cell types: red blood cells, white blood cells, and platelets. [5][6] It occurs most frequently in people in their teens and twenties but is also common among the elderly. It can be caused by heredity, immune disease, or exposure to chemicals, drugs, or radiation.

  3. Pernicious anemia - Wikipedia

    en.wikipedia.org/wiki/Pernicious_anemia

    Pernicious anemia is the most common cause of clinically evident vitamin B 12 deficiency worldwide. [14] Pernicious anemia due to autoimmune problems occurs in about one per 1000 people in the US. Among those over the age of 60, about 2% have the condition. [8] It more commonly affects people of northern European descent. [2]

    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 of them being deficiency and sickle cell anemia with together 60% of market share because of highest prevalence as well as higher treatment costs compared with other ...

    en.wikipedia.org/wiki/Pure_red_cell_aplasia

    Pure red cell aplasia affects the red blood cells in particular. 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.

  6. Megaloblastic anemia - Wikipedia

    en.wikipedia.org/wiki/Megaloblastic_anemia

    Megaloblastic anemia is a type of macrocytic anemia. An anemia is a red blood cell defect that can lead to an undersupply of oxygen. [1] Megaloblastic anemia results from inhibition of DNA synthesis during red blood cell production. [2] When DNA synthesis is impaired, the cell cycle cannot progress from the G2 growth stage to the mitosis (M) stage.

  7. Macrocytic anemia - Wikipedia

    en.wikipedia.org/wiki/Macrocytic_anemia

    A macrocytic class of anemia is an anemia (defined as blood with an insufficient concentration of hemoglobin) in which the red blood cells (erythrocytes) are larger than their normal volume. The normal erythrocyte volume in humans is about 80 to 100 femtoliters (fL= 10 −15 L). In metric terms the size is given in equivalent cubic micrometers ...

  8. Reticulocytopenia - Wikipedia

    en.wikipedia.org/wiki/Reticulocytopenia

    Aplastic Anemia. Reticulocytopenia is the medical term for an abnormal decrease in circulating red blood cell precursors (reticulocytes) that can lead to anemia due to resulting low red blood cell (erythrocyte) production. [1] Reticulocytopenia may be an isolated finding or it may not be associated with abnormalities in other hematopoietic cell ...

  9. List of hematologic conditions - Wikipedia

    en.wikipedia.org/wiki/List_of_hematologic_conditions

    Iron-deficiency anemia (or iron deficiency anaemia) is a common anemia that occurs when iron loss (often from intestinal bleeding or menses) occurs, and/or the dietary intake or absorption of iron is insufficient. In such a state, hemoglobin, which contains iron, cannot be formed. [5] Plummer–Vinson syndrome. D50.1.
