Title : Anemia: A Red Blood Cell Disorder
Anemia can be a clinical condition in which total number of red blood cells or the quantity of hemoglobin in blood declines than the normal level so the oxygen binding ability of hemoglobin can be decreased. The word anemia can be taken through a Greek word meaning lack of blood as hemoglobin deficiency prevails inside the blood. Hemoglobin present inside the red blood cells normally carries oxygen through lungs to the tissues in addition to anemia causes hypoxia in organs. As all human cells are dependent upon oxygen for survival, anemia can lead to a wide variety of symptoms depending upon degree of destruction caused. Anemia can be the most common disorder of blood in addition to different types of anemia are known depending upon the underlying causes. Anemia can be classified in a variety of ways for example, on the basis of morphology of the RBCs, underlying etiologic mechanisms in addition to discernible clinical spectra.
There are three main classes of anemia for example, hemorrhage characterized by excessive blood loss followed by hemolysis where excessive destruction of the blood cells take place in addition to ineffective hematopoiesis identified by deficient production of red blood cells. There are two major approaches for anemia. The first one can be kinetic approach which involves evaluation in addition to production, destruction in addition to loss of the red blood cells. The second approach can be the morphologic approach which involves characterization of anemia on the basis of size of red blood cells. The morphologic approach involves use of easily available in addition to low cost laboratory tests to identify anemia. The normal level of hemoglobin can be typically different in males in addition to females. Males suffer through anemia when the total hemoglobin levels become less than 13.5 gram/100ml while for females the idea must be less than 12.0 gram/100ml.
Classification
Anemia can be classified into following types:
1. Production versus destruction or loss
The kinetic approach gives the most relevant classification of anemia. This specific approach focuses on the evaluation of several hematological parameters for example, the blood reticulocyte count. This specific then classifies the defects concerned with decreased RBC production as well as its increased destruction in addition to loss. Clinical signs of destruction of RBCs show hemolysis inside the blood smear. Increased level of LDH suggests increased loss of blood cells.
2. Red blood cell size
The morphological approach classifies anemia on the basis of size of RBCs. This specific can be done either automatically or by analyzing the peripheral blood smear. The size of red blood cells can be reflected in terms of mean corpuscular volume (MCV). If the size of cell can be less than 80 fl then anemia can be said to be microcytic in addition to if the idea can be 80-100 fl then anemia can be normocytic. If the size of cell can be more than 100 fl then anemia can be classified as macrocytic. This specific approach quickly gives some idea about the cause of anemia for example microcytic anemia can be the result of iron deficiency. The peripheral blood smear often gives an idea about the white blood cells. Abnormal picture of white blood cells projects towards a defect inside the bone marrow.
a. Microcytic anemia
Microcytic anemia can be primarily the result of failure of synthesis or insufficient production of hemoglobin in blood in addition to numerous etiologies are also responsible for the idea. Iron deficiency anemia can be the most common type of anemia which may arise due numerous factors. In This specific type of clinical condition RBCs appear hypochromic in addition to microcytic when viewed under microscope. Iron deficiency anemia can be caused due to insufficient intake or absorption of iron inside the Centeng. Iron can be very important for hemoglobin production in addition to any insufficiency may result in decreased incorporation of hemoglobin inside the red blood cells. In United States about 20% females of childbearing age suffer through iron deficiency anemia while only 2% of males of same age group suffer through This specific clinical condition.
The prime cause of This specific form of anemia inside the premenopausal women can be excessive blood loss during menstrual cycle. Studies have shown which iron deficiency without anemia results in poor performance as well as low IQ in girls, although some socioeconomic factors may also be marked responsible for the idea. Iron deficiency sometimes also causes abnormal fissuring of angular sections of the lips. Iron deficiency anemia can also result through the bleeding of lesions of gastrointestinal tract. Fecal blood testing, occult blood testing, upper endoscopy in addition to lower endoscopy can help in detection of bleeding of the gastrointestinal tract. In men in addition to post-menopausal women the bleeding may be due to colorectal cancer. Parasitic infestations of parasites namely, Amoeba, hookworm, Schistosoma in addition to whipworm can be most common cause of iron deficiency anemia.
b. Macrocytic anemia
Macrocytic anemia can be further divided into megaloblastic in addition to non-megaloblastic macrocytic anemias. The major cause of megaloblastic anemia can be failure of DNA synthesis however, RNA synthesis occurs normally in addition to This specific results in restricted cell division of the progenitor cells. This specific form of anemia can also be found associated with the neutrophil hypersegmentation. The non-megaloblastic anemia can be most commonly found associated with alcoholism. Vitamin B12 deficiency can be the most common feature of This specific type of anemia in addition to the symptoms include peripheral neuropathy in addition to subacute combined degeneration of the cord resulting in balance difficulties of the spinal cord. various other features comprise red in addition to smooth tongue in addition to glossitis. The treatment of the vitamin B12 deficiency anemia was first given by William Murphy. He allowed the dogs to bleed till they became anemic in addition to then fed them a variety of substances in order to cure anemia. He concluded which ingestion of large amounts of liver resulted in diminished symptoms of anemia. George Minot in addition to George Whipple then isolated vitamin B12 through liver in addition to all these three scientists shared the Noble Prize in medicine in 1934.
c. Normocytic
This specific type of anemia occurs when the overall levels of hemoglobin keep on increasing nevertheless the size of red blood cells remain normal. This specific can be caused by acute blood loss, anemia due to chronic disease, hemolytic anemia in addition to aplastic anemia.
d. Dimorphic anemia
When two or more factors causing anemia act simultaneously at a time then This specific form of clinical condition comes into play.
e. Heinz Centeng anemia
Heinz bodies are formed inside the cytoplasm of RBCs in addition to appear like little dots when viewed under microscope. numerous factors are believed to be responsible because of This specific clinical condition in addition to some drugs may also participate in This specific form of anemia. the idea can be triggered in cats in addition to dogs by feeding them on onions in addition to zinc.
f. Hyperanemia
the idea can be a very severe form of anemia characterized by lowered concentration of hematocrit about less than 10%.
g. Refractory anemia
This specific form of anemia fails to respond against any treatment. the idea can be secondarily associated with the myelodysplastic syndromes. Iron deficiency anemia can also be placed under This specific category.
Causes
Anemia can be classified as a clinical condition with impaired red blood cell production, increased RBC destruction, blood loss in addition to fluid overload. numerous factors act simultaneously to cause anemia. Blood loss can be the most frequent symptom of anemia followed by iron deficiency. Anemia of impaired production can occur due to disturbance of proliferation in addition to differentiation of stem cells. This specific symptom can cause pure red cell aplasia followed by aplastic anemia which affects all types of blood cells. Insufficient production of erythropoietin causes renal failure in addition to anemia of endocrine disorders can also crop up. Disturbance of proliferation in addition to maturation of erythroblasts can be responsible for the appearance of pernicious anemia which can be a form of megaloblastic anemia caused by vitamin B12 deficiency resulting in impaired vitamin B12 absorption. This specific form of megaloblastic anemia also causes anemia of folic acid deficiency.
The levels of hematocrit also decline so erythropoietin response also diminishes resulting in anemia of prematurity. the idea generally occurs inside the infants of 2-6 weeks of age. Iron deficiency anemia also causes deficient heme synthesis. Thalassemias cause deficient globin synthesis. Myelophthisic anemia can be a very severe form of anemia where bone marrow can be replaced by various other materials like granulomas or malignant tumors. Anemias of increased red blood destruction are generally classified as hemolytic anemias in addition to are characterized by jaundice in addition to increased levels of low density lipoproteins. Trauma in addition to surgery also cause blood loss in addition to even the gastrointestinal tract lesions also result in chronic blood loss. Fluid overload causes decreased hemoglobin concentration in addition to apparent anemia
Signs in addition to symptoms
Anemia in some individuals may remain hidden as the symptoms do not arise very frequently. The signs in addition to symptoms may depend upon the underlying cause. Individuals suffering through anemia generally show non-specific symptoms like weakness, general malaise in addition to poor concentration. They may also report shortness of breath on exertion. In very severe forms the Centeng compensates for the lack of oxygen carrying capacity of blood cells by increasing the cardiac output. The patient may also complain of palpitation, angina, in addition to intermittent claudication of legs in addition to signs of heart failure. various other prominent symptoms include jaundice, bone deformities or leg ulcers. In severe forms tachycardia, bounding pulse, flow murmurs in addition to cardiac ventricular hypertrophy may also occur. Symptoms of heart failure may also arise. Pica, a symptom of iron deficiency arises after the consumption of non-food items like paper, wax, glass in addition to ice. Chronic anemia may also cause behavioral adjustments inside the children resulting in impaired neurological development. Restless legs syndrome can be very common in individuals with iron deficiency anemia. Less frequent symptoms include swelling of legs, arms, chronic heartburn, vomiting, increased sweating in addition to loss of blood in stool.
Diagnosis
A complete blood count can be typically used for the diagnosis of anemia. Apart through determining the number of red blood cells in addition to hemoglobin levels automatic counters also measure the size of red blood cells by using flow cytometry which gives a clear picture of anemia. Examination of a stained blood smear under microscope also gives a clear cut idea about This specific disease. Reticulocyte count in addition to kinetic approach are very commonly used in diagnosis. A recticulocyte count can be actually a quantitative measure of bone marrow's production of brand new red blood cells. If automated blood count can be not available then reticulocyte count can be taken into consideration for disease diagnosis.
Treatments
Treatments mainly focus on type in addition to cause of anemia. Iron deficiency anemia arising due to nutritional uptake can be generally rare in men in addition to post-menopausal women. Mild to moderate iron deficiency anemia can be treated by oral iron supplementation of ferrous sulfate, ferrous fumarate or ferrous gluconate. While taking iron supplements an individual may experience upset stomach as well as darkened feces. Vitamin C increases Centeng's ability to absorb iron so taking orange juice along with iron supplements may be of great help. Vitamin supplements taken orally or intramuscularly can help in replacing some of the specific deficiencies. Chronic anemia can be treated with chemotherapy in addition to the medical experts also advise use of recombinant erythropoietin to stimulate red blood cell production. In very severe cases blood transfusion becomes necessary. Anemia may be genetic. Hereditary disorders shorten the life span of red blood cells thereby, cause anemia. Hereditary disorders can also impair hemoglobin production in addition to cause This specific disease. Depending upon the degree of genetic abnormality anemias may be mild, moderate in addition to severe.
