What is poikilocytosis?
poikilocytosis Marked alteration of the shape of red blood cells which assume multiple morphology in the same individual (racket, star, pear, hourglass poikilocytes, etc.). The p. it is frequently found in anemia; it is often accompanied by anisocytosis, and in this case there is aniso-poikilocytosis.
What is erythrocyte anisocytosis?
Anisocytosis is characterized by the variability of the size of red blood cells (erythrocytes, RBCs) circulating in the peripheral blood and their diversity. It indicates some forms of anemia or hemoglobinopathies. The causes of anisocytosis are different and can be both physiological and derived from diseases.
What is Anisopoikilocytosis?
Anisocytosis is defined as a condition characterized by the presence of red blood cells (or erythrocytes) of various sizes in the peripheral blood. This haematological alteration is frequently associated with some forms of anemia, but it can also depend on numerous other pathologies or physiological situations.
What are Acanthocytes?
Acanthocyte (from the Greek akanthos, tip) is defined as a red blood cell with an anomalous shape. The anomaly consists of a serrated surface, with an irregular distribution of spicules, of variable number and shape.
What is Microcytosis?
Microcytosis, i.e. the presence of red blood cells with a lower than normal volume, is generally associated with an anemic condition, which can also signal the presence of tumors, such as lymphomas or ca.

How to cure microcytosis?
Microcythemia: how is Microcytosis treated? The management of microcythemia (microcytosis) is different depending on the type of triggering cause and, in general, can include the intake of iron and vitamin C supplements, diet modification and more or less recurrent blood transfusions .
What does red cell microcytosis mean?
Microcytosis is a condition characterized by the presence of smaller than normal red blood cells (or erythrocytes) in the peripheral blood. The presence of microcytes is frequently related to hypochromic anemia.
How does erythropoietin work?
EPO acts in the hematopoietic bone marrow by stimulating CFU-E erythroid progenitor cells, reducing their apoptosis and increasing their mitotic frequency, i.e. a faster differentiation to proerythroblast. The result is an increase in the availability of erythrocytes and hemoglobin.
What does hemoglobin mean?
Hemoglobin (Hb) is a protein found inside red blood cells. With its presence, it guarantees a fundamental function for the body: that of transporting oxygen from the lungs to the tissues, in all parts of the body.
What is the pathology in which spherocytes are formed?
By spherocytosis we mean a haematological picture characterized by a modification of the shape of red blood cells, which from their characteristic biconcave disc shape become spherical (spherocytes). Spherocytes are found in Minkowski-Chauffard disease and some immune-based hemolytic anemias.
What are megathrombocytes?
megathrombocyte (or megathrombocyte) sm [comp. mega- and thrombocyte (or thrombocyte)]. - In hematology, abnormally large platelets.
What are high erythrocytes?
A high number of erythrocytes in the blood can be the result of two different conditions: a lack of oxygen to fill, or an overstimulated bone marrow. Both of these conditions can, in turn, have multiple causes, some of which are entirely benign.
What disease is thalassemia?
What is Mediterranean anemia or thalassemia
Mediterranean anemia is synonymous with thalassemia, a hereditary blood disease due to the reduced or absent synthesis of one of the hemoglobin chains, the protein responsible for transporting oxygen throughout the body.
What is RDW CV in blood tests?
RDW (Red blood cell Distribution Width) is an erythrocyte index that measures the variability of the size of red blood cells in peripheral blood.
What is Anisochromia?
aniṡocromìa sf [comp. of aniso- and -chromia]. - In hematology, the presence, in a microscopic preparation, of cells and in particular of red blood cells colored with different intensity.
What does low Mchc mean?
A lower than normal MCHC is typically found in hypochromic anemia (under the microscope, erythrocytes appear lighter, as the amount of hemoglobin is reduced). The patient is likely not getting enough iron or has a hereditary form of anemia, such as thalassemia.
What if the hemoglobin is low?
Generally low hemoglobin levels can be caused by the following factors: anemia. iron deficiency. heavy menstrual loss or severe bleeding due to trauma or specific pathologies such as ulcer that triggers gastrointestinal bleeding.
What causes hemoglobin to drop?
Diet low in iron: an unbalanced diet low in iron can lead to situations of anemia that must be corrected with a more adequate diet or with an extra iron supplement.
What are the risks with low hemoglobin?
Low hemoglobin levels are a predictor of increased risk of death and complications among heart attack patients, according to a report in the Circulation: Journal of the American Heart Association.
What can cause erythropoietin?
Erythropoietin of exogenous (synthetic) origin is much more harmful to health than the endogenous one secreted by the kidney. We have already seen how the administration of this substance causes the production of abnormal red blood cells and increases the risk of developing blood and tumor pathologies (leukemia).
What tumors produce erythropoietin?
Tumor-associated erythrocytosis can occur when kidney tumors, cysts, hepatomas, cerebellar hemangioblastomas, or uterine leiomyomas secrete erythropoietin. Removal of the lesion is decisive. High-affinity hemoglobinopathies for oxygen are very rare.
Where does erythropoietin work?
EPO is a hormone produced mainly in the kidney and, to a small extent, by the liver. Its action is of fundamental importance for the production of red blood cells (erythrocytes), responsible for transporting oxygen from the lungs to the whole organism.
How do you tell if a person is Microcitemic?The first tests that are done to understand if a subject is microcitemic and the relative values are:
- complete blood count and morphological examination of the blood;
- study of the osmotic globular resistance;
- dosage of sideremia and ferritinemia;
- electrophoretic and / or chromatographic study of hemoglobins.
What does red blood cell hypochromia mean?
Hypochromia is a condition in which red blood cells (erythrocytes) are paler than normal. This situation is substantially superimposed on a reduced concentration of hemoglobin (Hb), the protein on which the red color of these blood cells depends.
What to eat with microcythemia?
For beta microcythemia, a healthy and balanced diet is recommended, with foods that help not only to introduce more iron, but to absorb it better, such as those rich in vitamin C (pineapple, kiwi, cherries, strawberries, citrus fruits, grape juice, currants , tomatoes, peppers, asparagus, raw young spinach seasoned with lemon, ...
