AbstractAnemia is a common clinical problem in critically ill patients and is associated with substantial red blood cell (RBC) transfusion requirements. However, RBC transfusion has significant risks, including adverse effects on the immune system. Although a low hemoglobin concentration may be tolerable, it may not be optimal for the critically ill patient. Thus, alternative therapies that can increase hemoglobin and avoid complications of RBC transfusion are desirable. Critically ill patients appear to have anemia identical to the anemia of chronic inflammatory disease with blunted erythropoietin production. Results of a recent randomized controlled trial in critically ill patients demonstrated that recombinant human erythropoietin (r-HuEPO, epoetin alfa) significantly reduced (by approximately 50%) the number of RBC units transfused (P <.002) and significantly increased hematocrit (P <.01) compared with placebo. There was no increase in mortality or adverse clinical events with therapy. Epoetin alfa may be an effective therapeutic approach to anemia in critically ill patients, decreasing the need for transfusion and achieving higher hemoglobin concentrations than generally attained with transfusion.Copyright 2001 by W.B.
