Resistance to recombinant human erythropoietin is a common condition in dialyzed patients with chronic kidney disease and is associated with more hospitalizations, increased mortality and frequent blood transfusions. The main cause of hyporesponsiveness to recombinant human erythropoietin in these patients is iron deficiency. However, a high proportion of patients does not respond to treatment,...

Numerous uremic patients on hemodialysis have pulmonary hypertension attributable to the presence of arteriovenous fistulas, vascular calcification, and endothelial dysfunction due to alterations in the balance between vasoconstrictive and vasodilatory substances. For these reasons, the effects of recombinant human erythropoietin, a drug widely used in patients on dialysis, on the pulmonary cir...

Onceweekly epoetin beta is highly effective in treating anaemic patients with lymphoproliferative malignancy and defective endogenous erythropoietin production. Br J Haematol 2003, in press. 13.

To determine if erythropoietin affects megakaryocytopoiesis, we measured acetylcholinesterase (AchE) activity, a marker of the murine megakaryocytic lineage, after the addition of human recombinant erythropoietin to serumless murine bone marrow cultures. Erythropoietin increased AchE activity substantially. Moreover, when the hormone was added to serumless cultures of 426 isolated single megaka...

Anaemia is a common problem in end stage kidney disease. Recombinant human erythropoietin (rHuEPO) is commonly used in management of such patients to maintain optimal hemoglobin levels and to minimise transfusion requirements. Acquired pure red cell aplasia (PRCA) is a rare complication of erythropoietin therapy due to development of anti-erythropoietin antibodies (anti-EPOabs). We report a pat...

Recently, a novel recombinant human erythropoietin (epoetin delta, Dynepo) has been marketed in the European Union for the treatment of chronic kidney disease, cancer patients receiving chemotherapy, and so forth. Epoetin delta is engineered in cultures of the human fibrosarcoma cell line HT-1080 by homologous recombination and "gene activation." Unlike recombinant erythropoietins produced in o...

We have used recombinant human erythropoietin (r-HuEPO) in children with chronic renal failure. There was significant improvement in anemia and wellbeing, along with regression of left ventricular mass and no change in the rate of decline of renal function. It is safe and effective in the pre-dialysis as well as the hemodialysis period. Considering the benefits of r-HuEPO, transplantation i...

OBJECTIVE The goal was to examine biochemical, neurophysiologic, anatomic, and clinical changes associated with erythropoietin administration to neonates with hypoxic-ischemic encephalopathy (HIE). METHODS We conducted a prospective case-control study with 45 neonates in 3 groups, a normal healthy group (N = 15), a HIE-erythropoietin group (N = 15; infants with mild/moderate HIE who received ...

The formation of red blood cells (RBCs) in the bone marrow is regulated by erythropoietin in response to a cascade of events. Anemia in the intensive care unit can be caused by a host of factors. Patients in the intensive care unit may have decreased RBC production and a blunted response to erythropoietin. Administration of recombinant human erythropoietin may stimulate erythropoiesis, increase...
