Abstract

Background: Erythropoiesis-stimulating agent (ESA) resistance remains incompletely understood among hemodialysis (HD) patients. Method: A retrospective, multicenter study was designed to analyze data from 1,934 patients followed for up to two years. The outcome measure was the erythropoietin resistance index (ERI), defined as erythropoietin dosage over a week divided by the post-HD weight and hemoglobin value. Results: Multivariate analysis revealed albumin, Kt/V, transferrin saturation, statin use and male gender to be inversely related to ERI, whereas parathyroid hormone and angiotensin-converting enzyme inhibitors (ACEI)/angiotensin receptor blockers (ARB) use were associated with higher ESA resistance. ERI was statistically lower in patients with higher levels of albumin (p < 0.001) and with higher transferrin saturation levels (p < 0.05). Discussion: The results allow for a better understanding of predictors of erythropoietin resistance among HD patients including not extensively studied factors such as statin and ACEI/ARB use.
