title: Alterations of erythropoiesis in chronic uremic patients treated with intermittent hemodialysis.
abstract: The in vitro growth of the blood burst-forming cells (BFU-E) of 9 chronic uremic patients, treated with intermittent hemodialysis three times a week has been studied at the time of maximum and minimum level of retained nitrogen catabolites. The effect of uremic sera on the vitro growth of normal BFU-E was also studied. The in vitro growth of blood BFU-E was shown to be greatly reduced in all uremic patients and dialysis did not modify their growth. The sera of uremic patients significantly inhibited the in vitro growth of normal blood BFU-E when it was taken at the time of maximum retention of nitrogen catabolites. However, inhibition of normal BFU-E growth was not seen when uremic sera were taken at the time of minimum retention of nitrogen catabolites. These data seem to indicate a long lasting suppression of BFU-E in chronic uremia due to serum inhibitor/s.
