Clasificacion de anemias by Carolina Isabel Guifarro Salgado on Prezi

Recent developments in the anemia of chronic disease. DNA point mutation producing amino acid substitution in hemoglobin beta chain A.

Published online Oct 7. A decrease in hemoglobin stimulates erythropoiesis through an increase in circulating erythropoietin.

Some infectious or parasitic diseases that are diagnosed with relative frequency are: Por lo cual, la clasificaciob diaria necesariamente debe aportar alrededor de 2 a 5 microgramos para cubrir las necesidades.

The normoregenerative anemias are in contrast to those characterized by inadequate marrow response to the degree anemizs anemia. Report of a WHO scientific group. Author information Article notes Copyright and License information Disclaimer.

Laboratory diagnosis of iron-deficiency anemia: A typical normal range is 0. In the case of hemolysis which takes place in the bloodstream rather than in the RESso-called intravascular hemolysisadditional biochemical phenomena are observed see diagram, below. The impairment of pluripotent stem cells usually produces pancytopenia anemia, leukopenia and thrombocytopenia. Journal List World J Gastroenterol v. In the same way, vitamin B12 deficiency is correlated with low serum levels, although there are clinical situations in which low serum levels are not correlated with vitamin B12 deficiency pregnancy, elderly patients, and those with low white blood cell counts.


These are the hyporegenerative anemias. The anemia of chronic disorders.

It is observed in patients that have immune hyperactivity. In the absence of intake of any of the drugs mentioned above or alcohol, the most frequent cause of microcytic anemia is nutritional deficiency[ 50 ]. It should be noted that, although there are many adjustments that can be made, one that cannot is decrease in the tissue requirement for oxygen.

The definition of anemia: The yolk sack is the origin of the first generation of erythrocyte precursors. If hemolytic anemia is suspected, the appropriate laboratory tests are antiglobulin test direct and indirectLDH, haptoglobin, total and conjugated bilirubin in serum, and salts and bile pigments in urine.

Small-bowel inflammatory disease is a widespread cause of chronic disease anemia. Generally, anemia must be fairly severe hemoglobin IV. As stated above, it can be hypo-regenerative or regenerative, which depends on the number of reticulocytes. Hemolytic anemia follows next in order of frequency.

J Gen Intern Med. Hemolytic anemia, although less frequent than the other, is the last option before considering the diagnosis of rare diseases. In adult life, the esophagus, stomach, bowel and liver are involved in the pathogenesis of different types of anemia caused by nutritional deficiency, bleeding or chronic inflammation.


Through a series of biochemical steps too boring to go into even here, the heme is changed into bilirubin. A few laboratory tests, such as blood count, ESR, serum ferritin, and serum iron and anemoas, are sufficient to focus the diagnosis.

Introduction Free oxygen, the plant kingdom’s unique gift to xnemias planet, is a highly reactive, dangerous substance capable of laying waste the delicate molecules that form the basis of life.

Classification of anemia for gastroenterologists

Anemia may exist as a laboratory finding in a subjectively healthy individual, because the body can, within ed, compensate for the decreased red cell mass.

Marrow biopsy is not usually performed just to measure the M: In consequence, these three parameters should be requested in the initial phase of the clasificaccion of normochromic anemia.

It has been said that all damage to the body from any pathologic state in the end is caused by hypoxia at some level.

E ratio tends to decrease in high-production states, and the marrow becomes hypercellular.
