Our comments were published in a letter to the Editor (see Hardy JF, Belisle S, Van der Linden P. Combined blood substitute and eryth-ropoietin therapy in a severely injured Jehovah’s witness. N Engl J Med 2002;347(9):696- 697). It is interesting to note that the rise in hemoglobin concentration reported in this patient with high-dose erythropoietin therapy is not supported by the data presented in the article by Gannon et al., lending further support to our comments.
