IHDIP: a controlled randomized trial to assess the security and effectiveness of the incremental hemodialysis in incident patients.

Background: Most people who make the transition to renal replacement therapy (RRT) are treated with a fixed dose thrice-weekly hemodialysis réegimen, without considering their residual kidney function (RKF). Recent papers inform us that incremental hemodialysis is associated with preservation of RKF, whenever compared with conventional hemodialysis. The objective of the present controlled randomized trial (RCT) is to determine if start HD with one sessions per week (1-Wk/HD), it is associated with better patient survival and other safety parameters.

Rationale and design of DiPPI: A randomized controlled trial to evaluate the safety and effectiveness of progressive hemodialysis in incident patients.

Introduction: Progressive haemodialysis (HD) is a starting regime for renal replacement therapy (RRT) adapted to each patient's necessities. It is mainly conditioned by the residual renal function (RRF). The frequency of sessions with which patients start HD (one or two sessions per week), is lower than that for conventional HD (three times per week).

Change from three times a week on-line hemodiafiltration to short daily on-line hemodiafiltration.

Background: Daily dialysis has shown excellent clinical results because a higher frequency of dialysis is more physiologic. On-line hemodiafiltration (OL-HDF) is a HDF technique that combines diffusion with high convection in which the dialysis fluid itself is used as a reinfusion solution. The aim of this study was to demonstrate the beneficial effect of the more effective dialysis schedule (daily dialysis) with the dialysis modality that offers the highest uremic toxin removal (on-line HDF).

Osteocalcin and myoglobin removal in on-line hemodiafiltration versus low- and high-flux hemodialysis.

Background: Removal of medium and large solutes is poor with low-flux (LF-HD) and limited with high-flux hemodialysis (HF-HD) and on-line hemodiafiltration (OL-HDF). In clinical practice, there are few in vivo solute markers. Osteocalcin is a protein with a molecular mass of 5,800 daltons, and myoglobin is a large molecule with a molecular mass of 17,200 daltons.
