Background: Darbepoetin alfa is an erythopoietic agent with a 3-fold longer elimination half-life than recombinant human erythropoietin (rHuEPO), which allows less frequent dosing, and hence it maintains an effective hemoglobin control at extended dose intervals compared with rHuEPO. This study assessed the efficacy and safety of unit doses of darbepoetin alfa for the treatment of renal anemia ...

The molecular mechanism of anemia that is hyporesponsive to recombinant human erythropoietin (rHuEPO) in hemodialysis patients without underlying causative factors has not been investigated fully in hematopoietic stem cell system. Circulating CD34+ cells (1 x 10(4)) were isolated from rHuEPO hyporesponsive hemodialysis patients (EPO-H; n = 9), patients who were responsive to rHuEPO (EPO-R; n = ...

BACKGROUND L-carnitine levels decrease rapidly and steadily with duration of hemodialysis, and carnitine depletion can impair response to recombinant human erythropoietin (rHuEPO). The study hypothesis was that L-carnitine supplementation during the first year of hemodialysis would improve this response. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS From October 2006 through March 2010, this ...

BACKGROUND Since only a portion of anemic patients outside the uremia setting benefit from erythropoietin treatment, a reliable means of predicting potential responders and nonresponders would be very useful. MATERIALS AND METHODS We retrospectively reviewed the clinical records of 58 patients with refractory anemia associated with various malignant disorders who had been treated with subcuta...

Recombinant human erythropoietin (rHuEpo) was introduced into clinical practice more than a decade ago, and has been found to be effective in the treatment of several types of anemia, including anemia of end-stage renal failure and cancer-related anemia. No study has suggested that Epo might have an effect on the biology of the disease, nor any survival advantage to cancer patients treated with...

Introduction: Patients with chronic kidney disease (CKD) have increasingly been diagnosed cognitive impairment. Glycogen synthase kinase 3β (GSK3β) is directly causing both phosphorylated tau (pTau) and amyloid β (Aβ) accumulation in Alzheimer’s (AD). GSK3β expression more abundant human platelets than other blood cells. Recombinant erythropoietin (rHuEPO) a common medicine for treating anemia ...

Background: In patients undergoing chemotherapy for cancer, anemia is part of the progression of the disease. Considering the effects of anemia on quality of life of the patients, the prevention and treatment of chemotherapy-induced anemia is crucial. This study was aimed to evaluate the efficacy of recombinant human erythropoietin in reducing the need for blood transfusion in children with sol...

Recombinant human erythropoietin is a glycoprotein hormone that stimulates erythropoiesis. In clonogenic assays of hematopoietic progenitors, high concen-trations of erythropoietin (Epo) increase CFU-E and diminish the number of granulocytes formed per culture plate. Fetal progenitors are more sensitive to these effects of Epo than progenitors from adults. We administered doses 50, 100, 200 IU/...

Previous phase I-II clinical trials have shown that recombinant human erythropoietin (rHuEpo) can ameliorate anemia in a portion of patients with multiple myeloma (MM) and non-Hodgkin's lymphoma (NHL). Therefore, we performed a randomized controlled multicenter study to define the optimal initial dosage and to identify predictors of response to rHuEpo. A total of 146 patients who had hemoglobin...
