Hemoglobin control, ESA resistance, and regular low-dose IV iron therapy: a review of the evidence

Abstract

Anemia management in hemodialysis patients has progressed following the introduction of erythropoiesis-stimulating agents (ESAs) and intravenous (IV) iron. However, maintaining a stable hemoglobin (Hb) level can be challenging. Patient comorbidities and variable dosage administrations of ESA therapy can lead to great variability in Hb concentrations over time. Fluctuating Hb levels is associated with increased complications. This article reviews factors that affect Hb control, with a focus on management practices (e.g., regular low-dose administration of IV iron) that can help improve anemia management.
