Predicting erythroid response to recombinant erythropoietin plus granulocyte colony-stimulating factor therapy following a single subcutaneous bolus in patients with myelodysplasia

Abstract

We randomized 21 patients with low-risk myelodysplastic syndromes (MDS) to receive a single subcutaneous bolus of recombinant erythropoietin (epoietin) +/- granulocyte-colony stimulating factor (G-CSF), or placebo and monitored erythropoietic response over 7 days. In this small study, the reticulocyte response at day 7 was highly predictive of subsequent response to a therapeutic trial of epoietin + G-CSF.
