Antierythropoietin antibody-induced pure red cell aplasia: posttransplant evolution.

ABSTRACT

Pure red cell aplasia is a rare complication of recombinant human erythropoietin (rHuEPO) treatment, which physicians should consider once the more frequent causes of hyporegenerative anemia have been excluded. To our knowledge, no pediatric cases have been described. In our patient, cyclosporin A treatment enabled a reduction in the number of transfusions and the risk of hyperimmunization. After transplantation, our patient's hemoglobin level has remained normal and stable.
