Extractions: related term: immune-mediated hemolytic anemia What is autoimmune hemolytic anemia (AIHA)? Normally red blood cells live about 4 months in dogs. As the cells age, they are removed and destroyed by other cells that are part of the immune system. New red blood cells are produced in the bone marrow at a rate that matches the destruction of older cells. In autoimmune hemolytic anemia, the immune system destroys red blood cells prematurely, faster than the rate at which new ones can be produced. The name says it all - anemia (reduced red blood cells) caused by hemolysis (destruction) by the body's own immune system (autoimmune). How is autoimmune hemolytic anemia inherited? Inheritance is unknown, but the condition is more common in certain breeds. What breeds are affected by autoimmune hemolytic anemia The old English sheep dog, cocker spaniel, and poodle have an increased susceptibility to this disorder, although it occurs in all breeds. It is more common in females than males. For many breeds and many disorders, the studies to determine the mode of inheritance or the frequency in the breed have not been carried out, or are inconclusive. We have listed breeds for which there is a consensus among those investigating in this field and among veterinary practitioners, that the condition is significant in this breed.

Extractions: What is anemia? Anemia is a common blood disorder, which is caused when there is a drop in hemoglobin or hematocrit in the blood. Anemia may be a symptom of another disease. The following are the most common symptoms of anemia. However, each individual may experience symptoms differently. Symptoms may include: abnormal paleness or lack of color of the skin increased heart rate (tachycardia) breathlessness, or difficulty catching a breath (dyspnea) lack of energy, or tiring easily (fatigue) dizziness, or vertigo, especially when standing headache irritability irregular menstruation cycles absent or delayed menstruation (amenorrhea) sore or swollen tongue (glossitis) jaundice, or yellowing of skin, eyes, and mouth

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.

Red blood cells are produced by stem cells in bone marrow. They contain hemoglobin, a protein that carries oxygen in the blood stream throughout the body. Hemolytic anemia occurs when red blood cells have an abnormally short life span. They're destroyed faster than bone marrow can produce them. The term for destruction of red blood cells is "hemolysis." Symptoms of hemolytic anemia may vary with each child. The following are some of the most common symptoms: Abnormally pale skin as well as jaundice or yellowing of skin and eyes Confusion Dark colored urine Dizziness, weakness or intolerance to physical activity

Extractions: As a group, anemias (conditions in which the number of red blood cells or the amount of hemoglobin in them is below normal) are the most common blood disorders. 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 involve conditions that interfere with normal red blood cell production. Disorders that affect the red blood cell membrane include hereditary spherocytosis, in which the normally disk-shaped red cells become spherical, and hereditary elliptocytosis, in which the cells are oval, rather than disk-shaped. Other hereditary conditions that cause hemolytic anemia include disorders of the hemoglobin, such as sickle cell anemia and thalassemia , and red blood cell enzyme deficiencies, such as G6PD deficiency. hypersplenism , in which a large, overactive spleen rapidly destroys red blood cells. Major symptoms of hemolytic anemias are similar to those for all anemias, including

Development of a therapeutic strategy for prevention of thromboembolism in canine immune-mediated hemolytic anemia (IMHA). A previous study at Purdue University documented a 30% mortality rate for canine IMHA, with thromboembolic events the most common cause of death documented at necropsy. Fifty percent of the dogs in this study had low plasma antithrombin (AT) activity. The most likely cause of low AT in dogs with IMHA is accelerated consumption due to disseminated intravascular coagulation (DIC), and DIC was either confirmed or suspected in 75% of the study dogs. A new ongoing study will determine whether replacement of AT and other anti- and pro-coagulant factors found in plasma can decrease the incidence of thromboembolism and improve survival in dogs with IMHA.

Normal red cells have a lifespan of 120 days, at which time they are destroyed primarily by the spleen. Hemolytic anemia is defined as the premature destruction of red cells either within the bloodstream or in organs such as the spleen. Mild hemolysis is compensated for by increased production of red cells by the marrow (up to eight-fold). Since it takes several days for the marrow to upregulate production of red cells, sudden, massive hemolysis is life-threatening. Severe chronic hemolysis can outstrip the marrow's ability to compensate, resulting in persistent anemia and even death from cardiac failure or side-effects of repeated transfusion (infections, iron overload).

http://www.gcvs.com/internists/imha.htm

Extractions: What is Immune-Mediated Hemolytic Anemia? Immune-Mediated Hemolytic Anemia (IMHA) is a serious and often life threatening disorder in dogs and cats. IMHA results from an inappropriate immune response to the animals own red blood cells. IMHA can be classified as primary or secondary. With primary IMHA, the immune system malfunctions and begins to treat the red blood cells as if they were foreign invaders and begins to produce antibodies against the red blood cells. This response is similar to what would occur against bacteria. No underlying cause for this inappropriate reaction can be identified. With secondary IMHA, an underlying disease condition such as infection, parasites, cancer or a reaction to a drug or vaccine causes a change in the red blood cells, which in turn stimulates the immune system to attack the cells. Autoagglutination is often associated with clotting disorders including pulmonary thromboembolism (PTE), which are blood clots in the lungs. Intravascular hemolysis tends to be more severe and carries a worse prognosis than extravascular hemolysis.

Issue 4, 2002. New Therapy For Cold Autoimmune hemolytic anemia. INTRODUCTION.Clinical Presentation Of Cold Autoimmune hemolytic anemia (CAIHA).
http://www.itxm.org/TMU2002/Issue4.htm

Extractions: LifeSource Blood Center INTRODUCTION Clinical Presentation Of Cold Autoimmune Hemolytic Anemia (CAIHA) CAIHA can be either acute or chronic. The acute type occurs after certain infections, such as, M. pneumoniae that reacts with all adult red blood cells bearing carbohydrate antigen I. The antibodies react best at cold temperature (4C) and are generally inactive at 37C. They sensitize red blood cells with complement component C3b. Anemia results from clearance of the complement-sensitized cells in the liver. Conventional Therapy Prednisone is beneficial in patients with IgG cold agglutinins of low titer. However, it is not helpful in the vast majority of cases because cold agglutinins are usually IgM and high titered. Splenectomy is usually ineffective because sensitized red blood cells are generally cleared in the liver. Plasma exchange is helpful only as a temporizing measure in acute situations. B-cell neoplasms that respond to cytotoxic drugs may also have a salutary effect on CAIHA. However, the course of CAIHA waxes and wanes with the activity of the neoplasm. Rituximab therapy Because the response to previous therapies for CAIHA is poor and the fact that the cold hemagglutinins are produced by clonal proliferation of CD20 B-lymphocytes, monoclonal anti-CD20 antibody (rituximab) therapy has been recently tried.

Extractions: Hemolytic anemia occurs when the bone marrow is unable to compensate for premature destruction of red blood cells by increasing their production. When the marrow is able to compensate, anemia does not occur. There are many types of hemolytic anemia, which are classified by the location of the defect. The defect may be in the red blood cell itself (intrinsic factor), or outside the red blood cell (extrinsic factor). Causes of hemolytic anemia include infection, certain medications, autoimmune disorders (such as Lupus), and inherited disorders. There are several different types of anemia. Prevention

http://www.aarda.org/page5.html

Extractions: Autoimmune Hemolytic Anemia Autoimmune hemolytic anemia is an autoimmune disorder which causes the premature destruction of red blood cells. There are several related autoimmune blood diseases. A normally red blood cell has a life span of approximately 120 days before the spleen removes it from circulation. Red blood cells are made in the bone marrow and released into circulation. In persons with autoimmune hemolytic anemia, the red blood cells are destroyed prematurely; and bone marrow production of new cells cannot make up for their loss. The severity of this disorder is determined by the length of time the red blood cell survives and by the capability of the bone marrow to continue red blood cell production. Autoimmune hemolytic anemia is a disorder that occurs in persons who have formerly had a normal red blood cell count. The disorder usually occurs in conjunction with some other medical condition, very often another autoimmune disease. It may sometimes occur alone and without a triggering factor. It affects twice as many women as men, specifically women in the childbearing years. Cold antibody hemolytic anemia most commonly affects elderly persons, and warm antibody hemolytic anemia can affect anyone at any age.

Krimer, DVM, DVSc Class of 2003 (Hiers) and Department of Pathology (Latimer, Bain, Krimer), College of Veterinary Medicine, The University of Georgia, Athens, GA 30602-7388 Introduction Immune-mediated hemolytic anemia (IMHA) is an accelerated destruction of red blood cells due to the attachment of immunoglobulin and/or complement to the erythrocyte membrane. It is a common cause of severe anemia and hemolysis in dogs with a mortality rate of over 40%. IMHA can be classified as primary or secondary depending on the cause of the red cell destruction. Secondary IMHA involves hemolysis due to an immunologic reaction to a "non-self" antigen. Possible causes include infection, chemical agents, drugs, or neoplastic disease. Primary IMHA is synonymous with idiopathic and autoimmune-mediated hemolytic anemia (AIHA). There is a true autoantibody specific for the self-antigen of the red cell membrane. Normally the immune system recognizes self-antigen and does not respond to it. This is the principle of self-tolerance. It is thought that when something triggers a change in immunoregulation, such as infection, there may be a loss of self-tolerance and subsequent autoimmune disease. There is a genetic predisposition for the development of AIHA
