Blood rheology and 2,3-diphosphoglycerate levels after erythropoietin treatment.

چکیده
Twenty-seven transfusion dependent patients with end-stage renal disease on long-term dialysis had blood cell counts, serum chemistries, blood pressure, and whole blood viscosity measured, as well as having transfusion requirements assessed. Three months after the institution of recombinant human erythropoietin (rHU-EPO) (75 u per kg per wk), there was an 88 percent fall in transfusion requirement. After four months, the hematocrit increased from 24 +/- 3.8 to 25.6 +/- 4.2 percent, mean corpuscular volume from 93 +/- 4.9 to 97 +/- 6.6 fl, 2-3-diphosphoglycerate (2,3-DPG) from 13.2 +/- 3.2 to 15.6 +/- 4.3 microM per g of Hb. Whole blood viscosity fell from 14.1 +/- 2.1 to 12.7 +/- 2.3 seconds, and ferritin levels fell from 3282 +/- 3889 to 2131 +/- 2441 ng per ml. In eight patients in whom the dose of rHU-EPO was further increased by up to 50 units per kg three times weekly for three months, the hematocrit rose further to 29.3 +/- 3.0 percent and the rise in hematocrit was accompanied by a further increase in 2,3-DPG to 17.9 +/- 2.8 microM per g of Hb (p < 0.03). There were no major side effects or vascular complications.

The pharmacokinetics of recombinant human erythropoietin (rHuEpo) administered intravenously has been investigated in a group of five patients with chronic renal failure who were dialysis-dependent. The half-life of circulating erythropoietin decreased from 7.9±OA hr (mean ±SO) at the beginning of treatment to 6.2±O.6 hr after 6 weeks and 5A±O.9 hr after 4 months of treatment. In spite of t...
متن کاملErythropoietin concentration during the development and recovery from iron deficiency in the rat.
The concentration of plasma erythropoietin was determined by radioimmunoassay during the progression of and subsequent recovery from iron-deficiency anemia in the rat. During the development of anemia, the plasma erythropoietin level rose as the hemoglobin (Hgb) concentration declined, reaching maximal levels when the Hgb was lowest. During the recovery from iron-deficiency anemia after institu...

Red cell phosphoglycolate phosphatase (PGP) and 2,3-diphosphoglycerate (2,3-DPG) were investigated in normal and anemic patients and rabbits. In hemolytic anemia and blood-loss anemia, characterized by a young red cell population, there was an increase in both phosphoglycolate phosphatase activity and 2,3-diphosphoglycerate levels. In aplastic anemia, the phosphoglycolate phosphatase activity w...
متن کاملAdaptation to Nocturnal Intermittent Hypoxia in Sleep-Disordered Breathing: 2,3 Diphosphoglycerate Levels: A Preliminary Study
The oxygenation of tissues depends on several factors such as blood flow, oxygen carrying capacity of the blood and the affinity of the hemoglobin for oxygen. Patients with an abnormality of one of these factors depend on adjustment in one or more other factors in order to maintain optimal tissue oxygenation. For instance, people who reside at high altitudes have two available modes of compensa...
