Maximizing the erythropoietin response: iron strategies.
Anemia is a significant cause of morbidity and lowers the quality of life of patients suffering from chronic kidney disease (CKD). Iron deficiency is the most important cause of erythropoietin (EPO) hyporesponsiveness in CKD. EPO administration significantly increases the costs of CKD management. It follows that paramount importance must be given to enhancing responsiveness to EPO thereby ensuring that the patient derives maximum benefit. Intravenous iron (IVI) administration has been used for decades to replenish body iron stores. Multiple preparations of Iron are available in the market. However, IVI administration is fraught with dangers like adverse drug reactions, susceptibility to infection, and, as recently postulated, direct cellular toxicity. Traditional approaches to IVI administration have focused on multiple administrations of lower doses for fear of adverse reactions. However, recent studies have demonstrated that higher doses can be safely administered in a single infusion, thereby reducing hospitalization costs and patient inconvenience. Newer preparations of IVI are relatively safer, easier to administer and efficacious. Preparations like Iron sucrose, ferumoxytol, ferric carboxymaltose and iron isomaltoside do not require test doses and allow higher doses to be administered at a time with cost and effect benefits.
