Abstract

Purpose of the study

Little information have been provided till now regarding the effect of high volume HDF (hv-OL-HDF) in respect to standard bicarbonate dialysis (BHD) in medium-long term protein-bound toxins removal.

Procedures

A randomised cross-over multicentre study (REDERT study) was designed to compare the effects of hv-OL-HDF and low-flux BHD on uremic toxins serum levels in 36 chronic dialysis patients followed for 13 months. Group 1 patients were treated with BHD (Treatment A) for 6 months, and afterwards, they were transferred to hv-OL-HDF for a further 6 months (Treatment B). Group 2 patients were treated with Treatment B for 6 months, and afterwards, they were transferred to Treatment A for a further 6 months. Total and free pre-dialysis indoxyl-sulfate (IS) and p-cresyl-sulfate (pCS) were determined starting a midweek dialysis session at baseline and after six months of hv-OL-HDF or BHD. IS and pCS, were simultaneously measured, by liquid chromatography/electrospray ionization-tandem mass spectrometry, Kt/v and pre and post-dialysis b-2microglobulin (b2MG) levels were measured every three months.

Results

Kt/V was significantly increased in hv-OL-HDF (from 1.47 ± 0.24 to 1.49 ± 0.16; p < 0.01) and was reduced in BHD (from 1.51 ± 0.2 to 1.36 ± 0.21; p < 0.001). The mean infusion volume in HDF was 20.9 ± 2.1 L with a mean total convective volume of 23.8 ± 2.3 L and a significant removal of b2MG was obtained in hv-OL-HDF at month 3 and month 6. Both free and total levels of IS and pCS were significantly reduced in hv-OL-HDF at month 6 in respect to BHD.

Conclusions

In the present study we confirm the assumption that post-HDF is an effective technique in small and protein-bound uremic toxins removal.Introduction
