Normal bone marrow has 30–70% blood stem cells, but in aplastic anemia, these cells are mostly gone and are replaced by fat. [ 5 ] [ 6 ] First-line treatment for aplastic anemia consists of immunosuppressive drugs —typically either anti-lymphocyte globulin or anti-thymocyte globulin —combined with corticosteroids , chemotherapy , and ...
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.
For the patient with isolated reticulocytopenia and anemia without significant disturbances in other cell lineages, the initial evaluation may include some of the following studies: [7] Complete blood count with differential; Peripheral blood smear; Type and Cross (in case transfusion is needed) Reticulocyte Production Index
Disorders such as iron deficiency anemia, sickle cell anemia, megaloblastic anemia and microangiopathic hemolytic anemia result in characteristic abnormalities on the blood film. [ 2 ] The proportions of different types of white blood cells can be determined from the blood smear.
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]
Normal reference range of RDW-CV in human red blood cells is 11.5–15.4%. [2] [1] If anemia is observed, RDW test results are often used together with mean corpuscular volume (MCV) results to determine the possible causes of the anemia. It is mainly used to differentiate an anemia of mixed causes from an anemia of a single cause.
This is a clinical laboratory finding. It is visualized by drawing blood from a patient and viewing the blood smeared on a slide under a microscope. Normal neutrophils are uniform in size, with an apparent diameter of about 13 μm in a film. When stained, neutrophils have a segmented nucleus and pink/orange cytoplasm under light microscope.
Blood smear showing red blood cells with basophilic stippling. Basophilic stippling, also known as punctate basophilia, is the presence of numerous basophilic granules that are dispersed through the cytoplasm of erythrocytes in a peripheral blood smear. They can be demonstrated to be RNA.
