The Changes of Clinical Markers, beta2-microglobulin and Oxidized LDL, after Converting to On-line Hemodiafiltration from High-flux Hemodialysis

Purpose : Hemodiafiltration with the on-line regeneration of ultrafiltrate (on-line hemodiafiltration, OL- HDF) provides better clearance of both small and large solutes than high-flux hemodialysis (HFHD) and may reduce inflammation and oxidative stress. The purpose of this observational study was to ascertain whether OL-HDF improves clinical markers after switching from HFHD to OL-HDF in patients with end-stage renal disease. Methods : Fourteen stable patients on HFHD for at least 6 months were switched to OL-HDF. We observed changes in subjective symptoms, the levels of hemoglobin, erythropoietin dose, Kt/V, URR, beta 2-microglobulin, plasma oxidized LDL (OxLDL) and CRP for twelve-months period. Results : There were improvements in subjective symptoms including fatigue, anorexia, insomnia and itching sensation (p
