The transcobalamins in polycythaemia vera.
Scand J Haematol. 1977 Nov; 19(5):453-62.SJ

Abstract

The unsaturated B12 binding capacity (UBBC) of the serum and the binding capacity of each of the 3 vitamin B12 binders--the transcobalamins (TC) I, II and III were determined in 21 patients with polycythaemia vera (PV) during the course of the disease and following treatment, using the recently described charged cellulose filter technique. High serum UBBC due to elevated serum TCIII was found in all patients. TCI was moderately elevated in patients who had leucocytosis with a shift to the left. The changes in serum TCIII and UBBC correlated with the activity of the disease. Chemotherapy resulted in a decrease in TCIII and UBBC. The decrease in TCIII and UBBC folowing chemotherapy may be observed before a decrease in the haematocrit and the leucocyte count occurs. Activation of the disease may be assessed by the elevation of TCIII and UBBC. The onset of acute myeloblastic crisis in 1 patient was associated with a decrease in TCIII and TCI levels and a rise in serum TCII. The determination of TCIII and UBBC may be helpful in differentiating true from secondary polycythaemia.
