| pure red cell 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) |
| pure red cell aplasia | A transitory arrest of red blood cell production which may occur in the course of a haemolytic anaemia, often preceded by infection, or as a complication of certain drugs; if the arrest persists anaemia may result. See: congenital hypoplastic anaemia. (05 Mar 2000) |
