| congenital aplastic anaemia | <haematology> A rare inherited type of aplastic anaemia which carries an increased risk to the patient of developing leukaemia. May be treated by bone marrow transplant. Origin: Gr. Haima = blood (13 Nov 1997) |
|---|---|
| congenital dyserythropoietic anaemia | A group of autosomal recessive anaemia's characterised by ineffective erythropoiesis, bone marrow erythroblastic multinuclearity, and secondary haemochromatosis. Three types are described: Type I, macrocytic, megaloblastic anaemia with erythroblastic internuclear chromatin bridges, type II,, normoblastic anaemia with multinucleated erythroblasts, type III, macrocytic anaemia with erythroblastic multinuclearity and gigantoblasts. (05 Mar 2000) |
| congenital hypoplastic anaemia | Congenital nonregenerative, familial hypoplastic, or pure red cell anaemia; erythrogenesis imperfecta; Diamond-Blackfan syndrome; autosomal recessive normocytic normochromic anaemia resulting from congenital hypoplasia of the bone marrow, which is grossly deficient in erythroid precursors while other elements are normal; anaemia is progressive and severe, but leukocyte and platelet counts are normal or slightly reduced; survival of transfused erythrocytes is normal; minor congenital anomalies are found in some patients. Synonym: congenital nonregenerative anaemia, Diamond-Blackfan anaemia, Diamond-Blackfan syndrome, erythrogenesis imperfecta, familial hypoplastic anaemia, pure red cell anaemia. (05 Mar 2000) |
| congenital nonregenerative anaemia | Congenital nonregenerative, familial hypoplastic, or pure red cell anaemia; erythrogenesis imperfecta; Diamond-Blackfan syndrome; autosomal recessive normocytic normochromic anaemia resulting from congenital hypoplasia of the bone marrow, which is grossly deficient in erythroid precursors while other elements are normal; anaemia is progressive and severe, but leukocyte and platelet counts are normal or slightly reduced; survival of transfused erythrocytes is normal; minor congenital anomalies are found in some patients. Synonym: congenital nonregenerative anaemia, Diamond-Blackfan anaemia, Diamond-Blackfan syndrome, erythrogenesis imperfecta, familial hypoplastic anaemia, pure red cell anaemia. (05 Mar 2000) |
| congenital spherocytic 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. Origin: Gr. Haima = blood (27 Sep 1997) |
| ABO haemolytic disease of the newborn | Erythroblastosis foetalis due to maternal-foetal incompatibility with respect to an antigen of the ABO blood group; the foetus possesses A or B antigen which is lacking in the mother, and the mother produces immune antibody which causes haemolysis of foetal erythrocytes. (05 Mar 2000) |
| acquired haemolytic icterus | Icterus and anaemia occuring in association with a moderate degree of splenomegaly, increased fragility of red blood cells, and increased amounts of urobilin in the urine. Synonym: icteroanaemia. Origin: G. Ikteros (05 Mar 2000) |
| beta-haemolytic streptococci | Those that produce active haemolysins (O and S) which cause a zone of clear haemolysis on the blood agar medium in the area of the colony; beta-haemolytic streptococci are divided into groups (A to O) on the basis of cell wall C carbohydrate (see Lancefield classification); Group A (in the strains pathogenic for man) comprises more than 50 types (designated by Arabic numerals) determined by cell wall M protein, which seems to be associated closely with virulence and is produced chiefly by strains with matt or mucoid colonies, in contrast to nonvirulent, glossy colony-producing strains; other surface protein antigens such as R and T (T substance), and the nucleoprotein fraction (P substance) seem to be of less importance. The more than 20 extracellular substances elaborated by strains of beta-haemolytic streptococci include erythrogenic toxin (elaborated only by lysogenic strains), deoxyribonuclease (streptodornase), haemolysins (streptolysins O and S), hyaluronidase, and streptokinase. Synonym: haemolytic streptococci. (05 Mar 2000) |
| complement haemolytic activity assay | Usual screening assay for complement. Dilutions of the serum to be tested are added to antibody-coated erythrocytes and the percentage of lysis is measured. The values are expressed by ch50, haemolytic complement units per milliliter, which is the dilution of serum required to lyse 50 percent of the erythrocytes in the assay. (12 Dec 1998) |
| haemolytic | Destructive to blood cells, resulting in liberation of haemoglobin. Synonym: haematolytic, haemotoxic, haematotoxic, haematoxic. (05 Mar 2000) |
| haemolytic chain | The haemolysis that occurs when complement is activated by the previously formed union of erythrocytes and specific antibody. (05 Mar 2000) |
| haemolytic disease of newborn | <haematology> A condition which develops in the foetus due to an incompatibility between the mother's blood type (RH factor) and the baby's. Maternal antibodies, which enter the foetal circulation during delivery attack the baby's red blood cells leading to haemolysis (rupture of the cells). Symptoms include an infant with an enlarged liver and spleen, swelling, jaundice and anaemia. (27 Sep 1997) |
| haemolytic disease of the newborn | Abnormal breakup of red blood cells in the foetus or newborn. This is usually due to antibodies made by the mother directed against the baby's red cells. It is typically caused by rh incompatibility, that is differences between the mother and baby uinvolving the rh blood group. (12 Dec 1998) |
| haemolytic gas | A poisonous gas, such as arsine, inhalation of which causes haemolysis with haemoglobinuria, jaundice, gastroenteritis, and nephritis. (05 Mar 2000) |
| haemolytic jaundice | <haematology> Haemolytic jaundice is a type of jaundice, where the skin takes on a yellowish hue, which occurs when red blood cells have been destroyed (by haemolysis). (09 Oct 1997) |
