NEW ORLEANS—Intravenous (IV) iron and erythropoietin are equally effective for treating anemia in most hemodialysis patients, British researchers concluded in a poster presentation at the American Society of Nephrology’s Kidney Week 2017 meeting.
In a randomized controlled trial, Damien Ashby, PhD, and colleagues at Imperial College Renal and Transplant Centre in London studied 194 stable HD patients who became moderately anemic (hemoglobin level 90-104 g/L). They randomly assigned patients to treatment with either IV iron (1 g divided over 5 consecutive sessions [IVFE group]) or increased erythropoietin (starting 3000 units per week or median increase of 50% [EPO group]). They followed up patients for as long as 18 months.
Dr Ashby’s team observed a positive hemoglobin response (an increase of at least 5 g/L by 2 months) in 54 (71.1%) of 76 IVFE patients and 62 (73.8%) of 84 EPO patients, a between-group difference that was not statistically significant.
In the IVFE group, compared with non-responders, lower hepcidin levels and lower mean cell volume predicted a positive hemoglobin response. In the EPO-treated patients, only low C-reactive protein predicted a positive hemoglobin response.
Ferritin levels did not predict hemoglobin response in either group.
