Effects of the recombinant human erythropoietin (rHuEPO) administration on hematologic parameters, red cell creatine and 2,3-diphosphoglycerate contents, in patients affected by end-stage renal disease.

Abstract Twenty patients with renal failure and severe anemia (hemoglobin range 6.6–8.7 g dl ) on thrice-weekly maintenance hemodialysis were treated with recombinant human erythropoietin (rHuEPO). After three months of intravenous (iv) therapy the hemoglobin increase averaged 2 g dl , and was steadily maintained even after two months of subcutaneous (sc) therapy. The significant increase of macrocyte counts, determined by an automated red blood cell counter after both steps of therapy, suggested the release of young red cells (large cells) into blood circulation. This assumption may be supported by the significant increase of the red cell creatine contents. 2,3-diphosphoglycerate (2,3-DPG) levels of the erythrocytes did not significantly change after rHuEPO administration.
