| icterohemolytic anaemia | <haematology> A hereditary disorder that leads to a chronic haemolytic anaemia due to an abnormality in the red blood cell membrane. This disorder is caused by a defective gene. Red cells are resistant to stress and rupture easily. Infants may appear jaundiced and pale. Fatigue, weakness and shortness of breath are other symptoms that may be seen in older patients. The spleen may also be enlarged. Treatment includes splenectomy (removal of the spleen). After this is accomplished the life-span of the red blood cells returns to normal. (27 Sep 1997) |
|---|---|
| dyshemopoietic anaemia | Any anaemia resulting from defective function of the bone marrow. (05 Mar 2000) |
| infectious anaemia | Anaemia developing as a complication of infection; probably results from depressed formation and short survival of erythrocytes and abnormal iron metabolism. (05 Mar 2000) |
| infectious anaemia virus, equine | A species of lentivirus, subgenus equine lentiviruses (lentiviruses, equine), causing acute and chronic infection in horses. It is transmitted mechanically by biting flies, mosquitoes, and midges, and iatrogenically through unsterilised equipment. Chronic infection often consists of acute episodes with remissions. (12 Dec 1998) |
| intertropical anaemia | An obsolete term for anaemia occurring in hookworm disease, chiefly necatoriasis. (05 Mar 2000) |
| iron deficiency anaemia | Hypochromic microcytic anaemia characterised by low serum iron, increased serum iron-binding capacity, decreased serum ferritin, and decreased marrow iron stores. Synonym: hypoferric anaemia. (05 Mar 2000) |
| isochromic anaemia | Any anaemia in which the concentration of haemoglobin in the erythrocytes is within the normal range, i.e., the mean corpuscular haemoglobin concentration is from 32 to 36%. Synonym: isochromic anaemia. (05 Mar 2000) |
| osteosclerotic anaemia | Anaemia due to compromise of erythropoiesis due to osteosclerosis. (05 Mar 2000) |
| ovalocytic anaemia | Anaemia characterised by elliptical erythrocytes (ovalocytes) resembling those observed normally in camels; 1 to 15% of erythrocytes in nonanaemic persons may be oval, but greater proportions are observed in certain patients with microcytic anaemia. See: elliptocytosis. Synonym: cameloid anaemia, ovalocytic anaemia. (05 Mar 2000) |
| target cell anaemia | Any anaemia with a conspicuous number of target cells in the peripheral blood; characteristic of the thalassaemias and also found in several haemoglobinopathies. (05 Mar 2000) |
| Ehrlich's anaemia | <haematology> This form of anaemia occurs when the bone marrow ceases sufficient red and white blood cell production. It may be induced by exposures to high levels of toxic chemicals, radiation and certain drugs. It is generally unresponsive to specific therapy, often accompanied by granulocytopenia and thrombocytopenia, in which the bone marrow may not necessarily be hypocellular or hypoplastic but fails to produce adequate numbers of peripheral blood elements. The term actually is all inclusive and most probably encompasses several clinical syndromes. Origin: Gr. Haima = blood (29 Sep 1997) |
| elliptocytary anaemia | Anaemia with elliptocytosis; a heterogeneous group of inherited anaemias having in common elliptical red cells on blood smear. The defect may reside in dysfunction or deficiency of proteins of the red cell membrane skeleton. Synonym: elliptocytotic anaemia. (05 Mar 2000) |
| elliptocytic anaemia | Anaemia characterised by elliptical erythrocytes (ovalocytes) resembling those observed normally in camels; 1 to 15% of erythrocytes in nonanaemic persons may be oval, but greater proportions are observed in certain patients with microcytic anaemia. See: elliptocytosis. Synonym: cameloid anaemia, ovalocytic anaemia. (05 Mar 2000) |
| elliptocytotic anaemia | Anaemia with elliptocytosis; a heterogeneous group of inherited anaemias having in common elliptical red cells on blood smear. The defect may reside in dysfunction or deficiency of proteins of the red cell membrane skeleton. Synonym: elliptocytotic anaemia. (05 Mar 2000) |
| toxic anaemia | Any anaemia resulting from the destructive effects of a chemical, metabolic poison, bacterial toxin, venom, and similar materials. (05 Mar 2000) |
