Exhaled breath volatile organic and inorganic compound composition in end-stage renal disease.

Aims: Patients with end-stage renal disease (ESRD) are characterized by uremia and increased oxidative stress. The aim of this study was to investigate the influence of hemodialysis on breath ammonia and volatile oxidative stress parameters.

Methods: Breath analysis was performed in 18 ESRD patients prior, during, and 30 minutes after a hemodialysis session.

Comparison of the new polyethersulfone high-flux membrane DIAPES HF800 with conventional high-flux membranes during on-line haemodiafiltration.

Background: Current modalities of renal replacement therapy allow only a limited removal of larger, possibly toxic molecules, which accumulate in uraemia. Recently, a haemodiafilter has been made available with the new, high-flux, polyethersulfone-based membrane DIAPES HF800. We performed a study to compare DIAPES HF800 with two conventional high-flux membranes in on-line haemodiafiltration (HDF), with respect to the removal properties for the two marker proteins, beta(2)-microglobulin (beta(2)m, 11.
