| anaemia, pernicious | A megaloblastic anaemia occurring in children but more commonly in later life, characterised by histamine-fast achlorhydria, in which the laboratory and clinical manifestations are based on malabsorption of vitamin b 12 due to a failure of the gastric mucosa to secrete adequate and potent intrinsic factor. (12 Dec 1998) |
|---|---|
| anaemia, refractory | Anaemia (a shortage of red blood cells) unresponsive to treatment. (12 Dec 1998) |
| anaemia, refractory, with excess of blasts | Chronic refractory anaemia with granulocytopenia, and/or thrombocytopenia. Myeloblasts and progranulocytes constitute 5 to 40 percent of the nucleated marrow cells. (12 Dec 1998) |
| anaemia, sickle cell | A disease characterised by chronic haemolytic anaemia, episodic painful crises, and pathologic involvement of many organs. It is the clinical expression of homozygosity for haemoglobin s. (12 Dec 1998) |
| anaemia, sideroblastic | Anaemia characterised by the presence of erythroblasts containing excessive deposits of iron in the marrow. (12 Dec 1998) |
| angiopathic haemolytic anaemia | A rare postpartum anaemia of unknown aetiology with uraemia and nephrosclerosis; may be a rare complication following use of contraceptive steroids. (05 Mar 2000) |
| antipernicious anaemia factor | <biochemistry> Member of the water soluble B vitamin group, important in the proper function of the nervous system and important in proper carbohydrate, protein and fat metabolism. (27 Sep 1997) |
| aplastic 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) |
| asiderotic anaemia | Yellowing or bleaching of plant tissues due to the loss of chlorophyll or failure of chlorophyll synthesis. Symptomatic of many plant diseases, also of deficiencies of light or certain nutrients. (18 Nov 1997) |
| autoimmune haemolytic anaemia | <haematology> A condition that results from the cellular destruction (haemolysis) of red blood cells due to antibodies formed to components on the surface of the red blood cells. Origin: Gr. Haima = blood (02 Jan 1998) |
| Bartonella anaemia | Anaemia occurring in infection with Bartonella bacilliformis and characterised by an acute febrile anaemia of rapid onset and high mortality. Occurs in central Andean mountains of northern South America; vector is phlebotomine sandfly, Lutzomyia. (05 Mar 2000) |
| Belgian Congo anaemia | A form of anaemia occurring in natives of Zaire (formerly the Belgian Congo), with associated oedema of subcutaneous tissues, depigmented regions in the skin, and various gastrointestinal disturbances; thought to result from deficiencies in nutrition. Synonym: Belgian Congo anaemia. (05 Mar 2000) |
| Biermer's anaemia | <haematology> A form of anaemia (low red blood cell counts) that results when the bone marrow fails to produce adequate numbers of red blood cells due to a deficiency in vitamin B12. Intrinsic factor, necessary for normal B12 absorption, may be the underlying cause for B12 deficiency if is not produced in the gastric glands (in the stomach). Origin: Gr. Haima = blood (27 Sep 1997) |
| brickmaker's anaemia | Anaemia associated with hookworm disease. (05 Mar 2000) |
| cameloid 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) |
