Low Hemoglobin Levels and Hypo-Responsiveness to Erythropoiesis-Stimulating Agent Associated With Poor Survival in Incident Japanese Hemodialysis Patients

Although erythropoiesis-stimulating agents (ESAs) are effective at treating anemia, the association between hemoglobin (Hb) levels and survival is still unclear, especially for the incident Japanese hemodialysis (HD) population. The Japan Erythropoietin Treatment (JET) Study is an open multi-center, prospective, observational study designed to evaluate the relationship between the maintenance of Hb levels and new HD patient prognosis after the first administration of epoetin beta. Landmark analyses were performed to examine the relationship between Hb levels at 6 months and survival. Among a total of 10,310 patients, 6631 completed the initial 6 months of epoetin beta treatment (induction phase) and were followed up for a further 2.5 years (maintenance phase). Three-year survival rate of patients with
