Plasma transcobalamins in haematological disorders.
Plasma UBBC-B12 and transcobalamins were measured in 112 patients suffering from different haematological disorders. The data showed different patterns of changes in plasma transcobalamin profile in different haematological disorders. Plasma UBBC-B12 and transcobalamins were significantly higher than normal in untreated chronic myeloid leukaemia, acute promyelocytic leukaemia, nutritional megaloblastic anaemia and in refractory anaemias with hypercellular marrow. Normal levels of these proteins were noted in chronic lymphatic leukaemias, in primary and secondary hypereosinophilic states and in multiple myeloma. Subnormal levels of these proteins were observed in hypoplastic anaemia and acute lymphoblastic leukaemia. Chronic myeloid leukaemia patients during blast crisis and acute myeloid leukaemia patients except those suffering from acute promyelocytic leukaemia showed varying pattern of plasma transcobalamins depending on type of blast crisis or FAB subtype of AML. The significance of these changes in plasma transcobalamins have been discussed along with the experience of other workers in this field.
