Patients with kidney disease—even without anemia—may benefit from iron treatment

New research indicates that treating iron deficiency, even in the absence of anemia, may benefit patients with kidney disease. The findings appear in an upcoming issue ofJASN.

Iron deficiency occurs in 30% to 45% of patients with chronic(CKD), and because iron is important for the production of red blood cells (or erythropoiesis), low levels can lead to anemia.

Clinical trials in patients withandhave shown that boosting patients' iron levels improves their cardiovascular health regardless of whether patients have anemia. Roberto Pecoits-Filho, MD, Ph.D., Murilo Guedes, MD (Arbor Research Collaborative for Health, in Ann Arbor, Michigan), and their colleagues looked to see if this might also be true in the Chronic Kidney Disease Outcomes and Practice Patterns Study (CKDopps), an observational study of patients with advanced non-dialysis CKD.

Among 5,145 patients with CKD from Brazil, France, the United States, and Germany who were followed for a median of 3 years, there were 47 deaths per 1,000 patients each year, and there were 48 major cardiovascular events per 1,000 patients each year. Iron deficiency was linked with higher risks of death and cardiovascular events, in patients with and without anemia.

"Intervention studies addressing the impact of iron deficiency treatment beyond its erythropoietic effects are necessary to challenge the anemia-focused paradigm of iron deficiency management in CKD, potentially fostering more optimal strategies for improving patient outcomes," said Dr. Pecoits-Filho. He noted that randomized controlledare needed to establish the role of iron treatment, even in the absence of anemia, in patients with CKD.
