Description of intervention(s) / exposure
Measurement of protein binding of small molecular weight toxins in peritoneal dialysis effluent assessed on 2 occasions 1 month apart
Measurement is undertaken with an HPLC assay for simultaneous determination of 4 uraemic solutes:P Cresol,P Cresol Sulphate,Indoxyl Sulphate,3-indole-acteic acid based on methods described by Calaf et al:J Chromatogr B Analyt Technol Biomed Life Sci. 879(23):2281-2286.2011

Outcomes
Primary outcome [1]

0
The degree of protein binding for each of the measured solutes is established by measuring total solute in the PD effluent and then separating protein from the PD effluent and measuring the remaining free level. The difference is the bound solute which is expressed as a percentage of the total

Bovine Serum albumin is added to the PD effluent at a range of concentrations likely to be achievable with wearable sorbent-based recycling PD. Total,bound and free solutes are measured.This enables the development of a binding curve related to protein concentrations
