The Effect of On-line Hemodiafiltratrion on Nutritional Status and Body Composition

Hemodialysis treatment thrice weekly with the high-flux FX-100 dialyzer (Fresenius Medical Care, Bad Homburg, Germany; membrane: Helixone®; surface: 2.2 m2; UF coefficient: 73 ml/h mm Hg; ß2-microglobulin-sieving coefficient: 0.8; albumin-sieving coefficient: 0.001), including a minimum target dialysis dose (Kt/Vurea) ≥1.2 and a session length of 3.0 to 6.0 h. Hemodialysis treatments were performed with the 5008 hemodialysis system (Fresenius Medical Care).

Post-dilution on line-hemodiafiltration treatment thrice weekly with the high-flux FX-100 dialyzer (Fresenius Medical Care, Bad Homburg, Germany; membrane: Helixone®; surface: 2.2 m2; UF coefficient: 73 ml/h mm Hg; ß2-microglobulin-sieving coefficient: 0.8; albumin-sieving coefficient: 0.001), including a minimum target dialysis dose (Kt/Vurea) ≥1.2 and a session length of 3.0 to 6.0 h. Post-dilution on line-hemodiafiltration treatments were performed with the 5008 hemodialysis system (Fresenius Medical Care), with automatic adjustment of the substitution fluid flow rate for maximising substitution volume while simultaneously avoiding haemoconcentration and filter clotting.
