Changing patterns of care in the management of anemia

There exists a potential for change in the approach to the management of the patient with chronic disease, specifically, the anemia of chronic disease (ACD). One of the components in the pathophysiology of ACD is inadequate erythropoietin response. Normally, as anemia develops, the erythropoietin level does not begin to increase until the hematocrit level decreases below 35%. However, the increase in the erythropoietin level is blunted in ACD. Increasing the hematocrit level by transfusion or recombinant human erythropoietin (r-HuEPO) treatment can subjectively and objectively improve the ACD patient's symptoms and performance. Although objective data in support of blood transfusions do exist, this treatment can carry risks of acute and chronic reactions, infection, and possibly immunosuppression. Treatment with r-HuEPO is a safer, nontransfusion means of increasing the hematocrit level of the patient with ACD symptoms.
