| 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) |
| traumatic anaemia | An acute anaemia caused by fairly sudden and rapid loss of blood, as by traumatic laceration of a relatively large vessel, erosion of an artery in a duodenal ulcer, haemorrhage in an ectopic pregnancy, or the result of such diseases as haemophilia and acute leukaemia. Synonym: traumatic anaemia. (05 Mar 2000) |
| equine infectious anaemia | <veterinary> virology> Viral disease of horses caused by the equine infectious anaemia virus (eiav; infectious anaemia virus, equine). It is characterised by intermittent fever, weakness, and anaemia. Chronic infection consists of acute episodes with remissions. (12 Dec 1998) |
| equine infectious anaemia virus | <virology> A retrovirus, of the Lentivirinae subfamily, and the cause of equine infectious anaemia. Synonym: swamp fever virus. (05 Mar 2000) |
| tropical anaemia | Various syndromes frequently observed in persons in tropical climates, usually resulting from nutritional deficiencies or hookworm or other parasitic diseases. (05 Mar 2000) |
| erythronormoblastic anaemia | Anaemia characterised by the presence of large numbers of nucleated red cells (normoblasts and erythroblasts) in the peripheral blood. Seen especially in newborns with haemolytic anaemia, such as that caused by Rh or ABO incompatibility. Synonym: erythroblastic anaemia. (05 Mar 2000) |
