  Hemolytic anemia - Wikipedia, the free encyclopedia
Hemolytic anemia is anemia due to hemolysis, the abnormal breakdown of red blood cells either in the blood vessels (intravascular hemolysis) or elsewhere in the body (extravascular).
The general classification of hemolytic anemia is either acquired or inherited.
In severe immune-related hemolytic anemia, steroid therapy is sometimes necessary.

 Hemolytic anemia
Hemolytic anemia is a disorder in which the red blood cells are destroyed prematurely.
Hemolytic anemias, which result from the increased destruction of red blood cells, are less common than anemias caused by excessive blood loss or by decreased hemoglobin or red cell production.
Inherited hemolytic anemias are caused by inborn defects in components of the red blood cells-the cell membrane, the enzymes, or the hemoglobin.

hemolytic anemia that is present from birth and in which the lifespan of red blood cells is diminished, such as occurs in hereditary spherocytosis.
anemia due to deficiency of ascorbic acid (vitamin C); in naturally occurring human scurvy the anemia is generally normocytic, although in experimentally induced vitamin C deficiency the anemia is of the megaloblastic type.
anemia in which the red blood cells have a bizarre spiculated shape and are destroyed prematurely, primarily in the spleen; it is an acquired form occurring in severe liver disease and represents an abnormality in the cholesterol content of the cell membrane.

 Anemia
In some cases anemia results from an inherited disorder, whereas in other cases the condition is caused by something in a person's environment, such as a nutritional problem, infection, or exposure to a drug or toxin.
Hemolytic ("hemo" means blood, "lytic" means destroying) anemia occurs when red blood cells are being destroyed prematurely and the bone marrow (the soft, spongy tissue inside bones that produces new blood cells) simply can't keep up with the body's demand for new cells.
Thalassemia major, also called Cooley's anemia, is a severe form of anemia in which red blood cells are rapidly destroyed and iron is deposited in the skin and vital organs.

 Microangiopathic hemolytic anemia - Wikipedia, the free encyclopedia
In medicine (hematology) microangiopathic hemolytic anemia (MAHA) is a subgroup of hemolytic anemia (anemia, loss of red blood cells through destruction) caused by factors in the small blood vessels.
It is identified by the finding of anemia and schistocytes ("bite cells") on microscopy of the blood film.
Automated analysers (the machines that perform routine full blood counts in most hospitals) are generally programmed to flag blood films that display red blood cell fragments or schistocytes.

 eMedicine - Anemia : Article by Marcel E Conrad, MD
Although geographic diseases, such as sickle cell anemia, thalassemia, malaria, hookworm, and chronic infections, are responsible for a portion of the increase, nutritional factors with iron deficiency and, to a lesser extent, folic acid deficiency play major roles in the increased prevalence of anemia.
Anemia solely due to hemolysis does not occur until RBCs are being destroyed at 6-8 times the normal rate, reducing the mean RBC lifespan to less than 20 days because of the bone marrow's capacity to undergo 6-fold hypertrophy and hyperplasia.
Splenectomy is useful in the treatment of autoimmune hemolytic anemias and in certain hereditary hemolytic disorders (ie, hereditary spherocytosis and elliptocytosis, certain unstable Hb disorders, pyruvic kinase deficiency).

 Autoimmune Hemolytic Anemia: Anemia: Merck Manual Home Edition
Autoimmune hemolytic anemia is a group of disorders characterized by a malfunction of the immune system that produces autoantibodies, which attack red blood cells as if they were substances foreign to the body.
When the cause of autoimmune hemolytic anemia is another disease, symptoms of the underlying disease, such as swollen and tender lymph nodes and fever, may dominate.
Autoimmune hemolytic anemia as the cause is confirmed when blood tests detect increased amounts of certain antibodies, either attached to red blood cells (direct antiglobulin or Coombs test) or in the liquid portion of the blood (indirect antiglobulin or Coombs test).

 Immune Mediated Hemolytic Anemia (IMHA) - VeterinaryPartner.com - a VIN company!
Immune-mediated hemolytic anemia is a condition where the patient's immune system begins attacking its own red blood cells.  What occurs on a microscopic level is that the branch of the immune system that produces antibodies begins to direct them against the patient's own red blood cells.
Anemia is the condition where one's red blood cell count is low.
These findings indicate the anemia is responsive, which means either that red blood cells are being lost via bleeding, possibly internal bleeding, or they are being destroyed by the immune system.
