Comparing Hemodiafiltration with and Without Hemoadsorption

Goals: The aim of the study is to assess the efficacy and safety of the combination of HDF + HA compared to HDF. To do this, we will evaluate the elimination of a wide range of molecular weight molecules, including small protein-bound solutes. Design: Prospective, single-center study. Each patient underwent two dialysis sessions with routine dialysis parameters in which HDF or HDF + HA treatment modality will be compared. Study subjects: 20 patients, stable on a thrice-weekly hemodialysis program, will be included. Local Ethics Committee will approve the study and patients will give informed consent. Interventions: Prospective collection of two dialysis sessions. The only difference among the sessions in each patient will be add or no sorbent cartridge. One session with FX60 Cordiax, helixone, Fresenius Medical Care in postdilution on-line hemodiafiltration and another session with the same dialyzer plus HA 130 cartridge. The order of these treatment sessions was randomly. Blood samples for analyses were taken for each patient in the same dialysis session of the week.
