Pure Red Cell Aplasia Induced by Antibodies against Human Recombinant Erythropoietin
Human recombinant erythropoietin (epoetin) is a very effective and safe biopharmaceutical. However, in 1998 the incidence of pure red cell aplasia (PRCA) induced by antierythropoietin (anti-EPO) antibodies in patients treated with epoetin started to increase. PRCA is a rare condition of non-regenerative anemia which can be associated with a variety of diseases and is in some cases of immunologi...
متن کاملAnti-erythropoietin (EPO) receptor monoclonal antibodies distinguish EPO-dependent and EPO-independent erythroid progenitors in polycythemia vera.
Erythroid progenitor cells isolated from patients with polycythemia vera (PV) proliferate and differentiate in methylcellulose in the absence of exogenous erythropoietin (EPO). To investigate the potential role of the erythropoietin receptor (EPO-R) in the pathogenesis of PV, we cultured bone marrow-derived or peripheral blood-derived erythroid progenitors in the presence of neutralizing monocl...
متن کاملPure red cell aplasia and anti-erythropoietin antibodies in patients treated with epoetin.
Recombinant human erythropoietin (epoetin) was first used for the treatment of renal anaemia in 1986. During the first 10 years of its use, epoetin-induced antibodies were a rare complication and only three cases of patients with epoetin-induced antibodies associated with pure red cell aplasia (PRCA) were published. Since 1998, however, there has been a significant increase in the number of pat...
متن کاملAutocrine stimulation by erythropoietin (Epo) requires Epo secretion.
Erythropoietin (Epo) autocrine stimulation has been implicated in erythroblastic leukemia. To examine whether this stimulation could occur intracellularly, we developed Epo autocrine models of stimulation in the human pluripotent UT-7 cell line. Retroviral expression of Epo totally abolished the growth factor requirement of UT-7 cells. Autonomous proliferation was not cell density-dependent and...
متن کاملPure red cell aplasia and associated thymoma
Pure red cell aplasia is a rare cause of anemia, caused by an absence of red blood cell precursors in the bone marrow. It is usually a paraneoplastic syndrome, associated most commonly with large-cell granular lymphocyte leukemia but also thymoma. For patients who present both pure red cell aplasia and thymoma, thymectomy leads to an initial remission of the aplasia in 30% of cases. However, su...
