ABSTRACT
The purpose of this work was to study the effects of correcting anemia on the distribution and partition of body fluids in dialyzed uremic subjects. We studied nine (7 m, 2 f) patients before and three months after the start of i.v. treatment with rHu-EPO, measuring total body water (TBW) with 3H2O, extracellular fluid volume (ECFV) with 35SO4 and plasma volume (PV) with 125I-SA. The intracellular water (ICW) and the interstitial fluid volumes (IFV) were derived by calculation from those measurements. The total blood volume (TBV) was calculated from the PV and the packed cell volume (PCV). Mean TBW, 482 +/- 45 (M +/- SD) ml/kg/bw and ECFV, 168 +/- 27.5 ml were significantly lower in patients than in nine matched normal controls, while the mean ICW (315 +/- 43 ml/kg) was similar. PCV before the start of rHu-EPO was 17.2 +/- 2.9% and had risen significantly to 31.3 +/- 4.8% (p = 0.000) after three months of therapy. Body weight (58 +/- 13 kg), TBW, ECFV and ICW did not change. TBV before rHU-EPO was 68.7 +/- 7.5 ml/kg and remained nearly unchanged, while PV fell significantly from 57 +/- 9 to 48 +/- 8 ml/kg (p < 0.025), with the calculated IFV rising from 111 +/- 25 to 127 +/- 27 (p = 0.000). The PV/IFV ratio decreased from 0.53 +/- 0.12 to 0.38 +/- 0.09 (p = 0.001). The decrease in PV/IFV ratio was paralleled by simultaneous increase in PCV in all but one patient.(ABSTRACT TRUNCATED AT 250 WORDS)
