In vivo effects of recombinant human erythropoietin on bone marrow hematopoiesis in patients with chronic renal failure.
Eur J Med Res. 1998 Dec 16; 3(12):564-70.EJ

Abstract

Studies of hemopoietic progenitors and precursors in bone marrow before and after two months of recombinant human erythropoietin (rhEpo) therapy in 12 patients with uremic anemia are the subject of this investigation caried out in order to have a better insight into the effect of Epo in vivo. Eight patients were on hemodialysis and four others were predialysis patients with chronic renal failure. The starting dose of rhEpo was 30-50 U/kg bw and was increased by 50 percent every four weeks. The mean hemoglobin values rose from 6.08 +/- 1.03 to 9.8 +/- 1.98 g/dl at the time of study. The number of bone marrow derived erythroid colonies, both early (BFU-E) and late (CFU-E) were found to be higher than subnormal values, found before the therapy. The percentage of erythroid progenitors in cell cycle increased to higher than normal values for BFU-E and to normal values for CFU-E. At the same time granulocytic progenitors (CFU-GM) decreased to the range of normal values (67.3 per 10 superset5 cells). Slightly increased Epo levels (approx. 30mU/ml) during the replacement therapy were optimal for correction of anemia. The rhEpo therapy induced an increase of percentage of erythroblasts and the decrease of myeloid to erythroid ratio (M/E) in the bone marrow. Only in predialysis patients in whom the target hemoglobin values were achieved by rhEpo therapy at the time of the study the percentage of erythroblasts in the bone marrow increased to normal values. Increase of erythroblasts in bone marrow in patients under two months of substitutive therapy with rhEpo with the increase of both, early and late erythroid progenitors we have observed, is significant indicating the stimulative effect of rhEpo on all subsets of erythropoiesis leading to normalization of erythropoiesis at all levels. No stimulative effect of rhEpo replacement therapy on granulopoiesis was observed.
