Please check the synonyms listing to find the alternate name(s) and disorder subdivision(s) covered by this report. Warm Antibody Hemolytic Anemia is an autoimmune disorder characterized by the premature destruction of red blood cells by the body's natural defenses against invading organisms (antibodies). Normally, the red blood cells have a life span of approximately 120 days before they are removed by the spleen. In an individual affected with Warm Antibody Hemolytic Anemia, the red blood cells are destroyed prematurely and bone marrow production of new cells can no longer compensate for their loss. The severity of the anemia is determined by the time the red blood cells are allowed to survive and by the capacity of the bone marrow to continue new red blood cell production. Immune Hemolytic Anemias are subdivided by the optimal temperature at which the antibodies destroy red blood cells. As their names imply, Warm Antibody Hemolytic Anemia occurs at temperatures of 37 degrees centigrade or higher while Cold Antibody Hemolytic Anemia usually occurs at approximately to 10 degrees.

It is identified by the finding of anaemia 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 The most important causes are: In all causes, the mechanism of MAHA is the formation of a fibrin mesh due to increased activity of the system of coagulation . The red blood cells are physically cut by these protein networks, and the fragments are identical to the schistocytes seen on light microscopy.

When this happens, it causes a form of anemia edit Hemolysis is an important factor in medical tests, as a blood sample may become hemolysed with prolonged storage or when complications arise during venipuncture . For example, when a blood sample is collected, hemolysis is rare when the collection is straight forward. On occasions when a patient's veins are uncooperative (such as collapsing under the pull of a vacuum from a syringe or a modern vacuum tube), the problem becomes more prevalent. The red cells in the blood are literally smashed on their way through the needle , often due to excessive suction. This results in a poor sample. Hemolysis may cause interference with the test results for a patient, but this is mostly limited to biochemistry tests. edit Normally, a red blood cell survives 90 to 120 days in circulation: about 1% of human red blood cells break down each day, which matches the production rate.

Home Autoimmune hemolytic anemia Autoimmune hemolytic anemia Programs that treat this condition Anemia and RBC Disorders Autoimmune hemolytic anemia is a condition where the body destroys its red blood cells faster than they can be produced. The condition can be intrinsic caused by a disorder within the red blood cells themselves, or extrinsic prompted by infection, medications, antibodies, or other causes. Treatment for hemolytic anemia may include blood transfusions, corticosteriod medications, intravenous immune globulin, and sometimes removal of the spleen or immunosuppressive therapy.

The premature breakdown of red blood cells, an event that can occur due to a wide range of disorders and conditions, is known as hemolysis . When the bone marrow of an individual is unable to produce enough red blood cells to offset those that are precipitately lost, hemolytic anemia ensues. In instances of mild hemolytic anemia, the patient may be asymptomatic, but in severe cases, ones life can become endangered. The elderly and people with cardiovascular problems are at greatest risk of death from hemolytic anemia, but overall the mortality rate associated with the disease is quite low. Some of the most common symptoms of hemolytic anemia include weakness, fatigue, darkened urine, pallor, jaundice, shortness of breath, fever, confusion, and rapid heart rate. Though the readily observable symptoms of hemolytic anemia are similar to those of other types of anemias, there are several signs that can aid in a more specific diagnosis. Some key signs of the hemolytic form of the condition are only recognizable with the aid of a microscope. For instance, when blood smear examination reveals red blood cell fragments, an unusually large number of

Extractions: Background Thomas Hirose, M.D. is a board certified pathologist with subspecialty expertise and board certification in Transfusion Medicine. As director of the Blood Bank in several hospitals, it is his job to oversee all transfusion reactions which may occur from the utilization of blood products. In addition, any patient with a bleeding problem usually comes to his attention because of the therapeutic decisions which need to be made regarding the transfusion of blood products. This is how he made a difference for the patient. Recently I received a call from an Internist regarding a 55 year male patient who was severely anemic (hematocrit 18%) and was found to have a positive DAT. The patient was thought to have a small retroperitoneal hemorrhage . The attending physician was reluctant to transfuse any blood and questioned whether he should premedicate this patient with steroids, aspirin and benadryl because there was a positive direct Coombs assay. The patients serologic evaluation revealed a 2+ reaction with anti-IgG Coombs reagent and 4+ anti-C3d. The indirect Coombs assay was negative. This pattern suggested that the patient may have been exposed to a medication (Cefotetan, Volaren, Unisyn etc.) which could induce a positive direct Coombs and could also be associated with red cell hemolysis.

Extractions: Red Blood Cell Destruction In mammals, the red blood cell is basically a small bag of hemoglobin, the protein which binds oxygen in the lungs, carries it and releases it to other tissues. A normal canine red blood cell lives 120 days and dies when it either becomes too stiff to fold itself through the tiny capillaries of the circulation (and it simply bursts trying to do so) or it cannot generate enough energy to keep itself alive. The spleen is responsible for removing old red blood cells. The spleen possesses many tortuous, winding blood vessels where red blood cells may break if they are not supple enough to pass through. The spleen then collects the hemoglobin. Bilirubin, a pigment made from old hemoglobin, is a by-product of this process. Bilirubin is sent to the liver to be conjugated, a chemical process enabling the bilirubin to be excreted in bile, a digestive emulsifier secreted by the liver. Bilirubin is responsible for the color of feces. What is Hemolysis?

Index Anemia is a blood disorder that is defined as: When there are not enough red blood cells or there is too little hemoglobin, the blood is not able to carry enough oxygen to all parts of the body. There are several forms of anemia, such as: iron deficiency anemia hemolytic anemia vitamin B-12 deficiency anemia folic acid deficiency anemia anemia caused by inherited abnormalities of RBCs (for example, sickle cell anemia and thalassemia) anemia caused by chronic (ongoing) disease, such as rheumatoid arthritis.

Differentiating among these conditions is critical because they respond to different therapeutic modalities and the laboratory is often critical in making these distinctions. Table 1.

Thrombocytopenia, microangiopathic hemolytic anemia, moderately abnormal liver function tests (LFT) and usually mildly abnormal renal function tests are characteristically present. Antepartum preeclampsia developes most commonly in nulliparous women and is characterized by proteinuria, edema and hypertension. Hemolysis is rare, and mild thrombocytopenia is present in 10-15% of cases. LFTs are minimally affected, and renal failure is rare. This patient did not have hypertension and LFTs were only transiently abnormal, making HELLP syndrome and preeclampsia less likely.

This takes place in response to medication. The resulting low red blood cell count is known as anemia What is going on in the body? Red blood cells transport oxygen to tissues of the body. In some people, medications can cause the immune system to attack and destroy red blood cells. This is known as hemolysis. What are the causes and risks of the disease? Hemolytic anemia brought on by an immune reaction to a drug can be caused by a number of medications. Examples include many types of antibiotics and certain blood pressure drugs, among others.
