  Anaemia
Anaemia of folate deficiency is a decrease in the red cells in the blood caused by folate (folic acid) deficiency.
Haemolytic anaemia occurs when the bone marrow is unable to compensate for premature destruction of red blood cells by increasing their production.
Haemolytic anaemia due to G-6-PD deficiency is a hereditary, sex-linked, enzyme defect that results in the breakdown of red blood cells when the person is exposed to the stress of infection or certain drugs.

In non-vegans the main cause of vitamin B12 deficiency is pernicious anaemia, which is an auto-immune condition with antibodies being produced against gastric parietal cells in 90% and intrinsic factor in 70% of patients.
The aetiology of haemolytic anaemia may be divided into stimuli outside the red cell membrane, problems within the red cell membrane and defects within the red cell itself.
An example of a haemolytic anaemia where the stimulus lies outside the red cell membrane is auto-immune haemolytic anaemia.

 Haemolytic Anaemia
Haemolytic anaemia is characterized by the destruction of the red globules, due to an intrinsic defect in the cellular membrane or enzymes.
These are haemolytic anaemias resulting from a mutation which affects the synthesis of the haemoglobin.

Haemolytic anaemia occurs when red blood cell destruction is increased as the result of an inherited or an acquired condition in which red blood cells break up more quickly than normal.
Acquired haemolytic anaemia may also be caused by the presence of antibodies (proteins produced by the body to fight infection) in the blood.
A condition called hypersplenism, in which the spleen is large and overactive, destroying the red blood cells too quickly, causes another form of haemolytic anaemia.

 Content
Autoimmune haemolytic anaemias (AIHA) are acquired disorders resulting from increased red cell destruction due to red cell autoantibodies.
These anaemias are characterized by the presence of a positive direct antiglobulin (Coombs') test, which detects the autoantibody on the surface of the patient's red cells (Fig.
These anaemias may occur at all ages and in both sexes, although they are most frequent in middle-aged females.

 Bawarchi: Health and Nutrition: How To Prevent Nutritional Anaemia?
Anaemia is a condition where oxygen carrying capacity of the blood is reduced due to reduced haemoglobin concentration in the blood.
Nutritional anaemias are group of condition caused by deficiency of nutrients required for the formation of haemoglobin or red blood cells.
These anaemias are due to reduced intake, impaired absorption, increased losses or may be due to the increased demand.

Anaemia can be divided into deficiency anaemias (iron deficiency and vitamin B12, and folate deficiency) and haemolytic anaemia, which can be acquired or inherited.
The most common is pernicious anaemia, which is an auto-immune disorder causing gastric atrophy that results in a reduction in the number of gastric parietal cells and a reduction in intrinsic factor.
Glucose-6-phosphate dehydrogenase deficiency is an anaemia due to a disorder of metabolism.

 Biology_stomatocytosis
Other inherited haemolytic anaemias, hereditary spherocytosis and hereditary elliptocytosis, are caused by problems in the supporting network; stomatocytosis is a problem with the sealing sheet.
The cell can be attacked by antibodies ('autoimmune haemolytic anaemia'); or for genetic reasons, a number of proteins (the functioning components) within the cell may not work properly.
For instance, its principal protein, haemoglobin, may be faulty, as in sickle cell disease; or one of the proteins that maintains the energy supply may be faulty; or one of the 200 or so proteins of the membrane may be not be working properly.

 Anaemia   (Site not responding. Last check: 2007-11-01)
Sickle cell anaemia is an inherited problem that can cause minor difficulties as the "trait" (when you carry one mutated gene from one of your parents) but severe clinical problems as the "disease" (when you carry two mutated genes, one from each of your parents).
In milder forms, anaemia is usually mild or absent, and the disease may be detected by finding small blood cells on a routine FBC.
The "major" form (due to inheriting all thalassaemia genes) is more severe and may result in growth problems, jaundice (yellowing of the skin and whites of the eyes), and severe anaemia.

 Statements of Principles — Thrombocytopenia
"autoimmune haemolytic anaemia" means a large group of anaemias involving autoantibodies against red cell antigens.
Those autoimmune haemolytic anaemias due to warm-receptive antibodies, usually IgG but occasionally IgM or IgA, may be idiopathic or secondary to autoimmune diseases, haematologic neoplasms, viral infections, or immunodeficiency diseases, and usually involve sequestration of sensitised erythrocytes by the spleen.
Those autoimmune haemolytic anaemias due to cold-reactive antibodies, usually IgM but occasionally IgG, include cold agglutinin syndrome and paroxysmal cold haemoglobinuria and usually involve complement-dependent intravascular haemolysis or sequestration of erythrocytes by the liver;

Any conditions that cause a rapid breakdown of blood cells, such as haemolytic anaemias, can place great strain on the spleen and make it enlarge.
For example, if red blood cells are deficient, anaemia will be the result (with symptoms including fatigue and pallor).
Most cases of hypersplenism are caused by disorders somewhere else in the body, such as cirrhosis of the liver.

The factory that breaks down old or abnormal red cells is the spleen.
In haemolytic anaemias, where the red cells are abnormal, the spleen ends up working overtime and becomes enlarged.
In fact anaemia and jaundice occurring together with splenic enlargement usually alerts one to the possibility of a haemolytic anaemia.
