The definition blood doping was introduced by the media in the 1970s to describe the use of blood transfusion to increase red cell mass artificially, and in turn to enhance both maximal oxygen uptake and performance in endurance sports. Since the late 1980s blood doping is no longer achieved by autologous transfusion but instead through administration of recombinant human erythropoietin (rHuEpo).

This study appraised the veracity of claims that athletes can evade doping controls by injecting microdoses of recombinant human erythropoietin (rHuEPO), which rapidly disappear from the circulation. We confirmed that microdosing can reduce the window of detection to as little as 12-18 hours post-injection, suggesting that authorities must adopt appropriate counter measures.

We report the efficacy, tolerability and cost of erythocytoapheresis plus recombinant human erythropoietin (rHuEPO) in three patients with severe hereditary hemochromatosis (HH). Results indicate that this regimen could be a valid therapeutic alternative in complicated HH patients. Its cost, however, limits its use to patients whose clinical conditions prevent a proper phlebotomy regimen.

Myasthenia gravis (MG) is an autoimmune disorder characterized by weakness and fatigability of skeletal muscles. Erythropoietin (EPO) is a cytokine required to maintain erythroid cells. Recombinant human EPO (rHuEPO) was found to act also on immune cells. Beneficial effects of rHuEPO therapy have been demonstrated in several experimental autoimmune models. We have tested the effect of rHuEPO on...

Recombinant human erythropoietin (rHuEPO), such as the approved agents epoetin alfa and epoetin beta, has been used successfully for over 20 years to treat anemia in millions of patients. However, due to the relatively short half-life of the molecule (approximately 8 hours), frequent dosing may be required to achieve required hemoglobin levels. Therefore, a need was identified in some anemic pa...

The invention of recombinant human erythropoietin (rHuEpo) for the treatment of renal anaemia was a hallmark in the care of patients with renal insufficiency. Recently published guidelines (European Best Practice Guidelines, NKF-DOQI) have set the target haemoglobin to be reached by treatment with rHuEpo to >11 g/dl. Normalizing haemoglobin levels may reduce morbidity and mortality and improve ...

Patients with hemolytic-uremic syndrome (HUS) can rapidly develop profound anemia as the disease progresses, as a consequence of red blood cell (RBC) hemolysis and inadequate erythropoietin synthesis. Therefore, RBC transfusion should be considered in HUS patients with severe anemia to avoid cardiac or pulmonary complications. Most patients who are Jehovah's Witnesses refuse blood transfusion, ...

Paroxysmal nocturnal hemoglobinuria (PNH) is characterized by intravascular hemolysis leading to anemia and other clinical manifestations. Transfusions are often required to support hemoglobin at tolerable levels. A PNH patient with aplastic anemia was treated with the complement inhibitor eculizumab, followed by concurrent treatment with recombinant human erythropoietin (rHuEpo). Eculizumab al...

In an attempt to reduce or eliminate homologous red blood cell transfusion requirements during allogeneic bone marrow transplantation (BMT), we instituted a novel program whereby recombinant human erythropoietin was administered to pairs of BMT donors and recipients. Eleven recipients and their HLA-matched donors were enrolled. Donors treated with recombinant human erythropoietin (rHuEPO) were ...
