Caring for the renal failure patient: optimizing iron therapy.

The effectiveness of anemia management in patients with end stage renal disease (ESRD) has increased over the past 4 years. However, approximately 26% of treated patients still do not meet the minimum hemoglobin (Hgb) value of 11 g/dl that is recommended by the K/DOQI Clinical Practice Guidelines (National Kidney Foundation [NKF], 2001). One of the main obstacles to good patient outcome may be iron deficiency, which is common in both the predialysis and dialysis period. Since iron is needed for Hgb synthesis, iron depletion exacerbated anemia and reduces the response to recombinant erythropoietin (rEPO) therapy. Health care providers can significantly improve patient outcome by addressing iron deficiency more rigorously. A good starting point is the establishment of an iron deficiency management protocol that includes early evaluation of iron status and aggressive iron therapy. Iron therapy, in turn, can be optimized by administering safe and effective iron supplements and by implementing maintenance iron regimens to prevent the recurrence of iron deficiency. By making these simple improvements to their treatment approach, clinicians can enhance the effectiveness of anemia management in patients with ESRD.
