Outcomes
Primary outcome [1] 238281 0
Change in highly sensitive C reactive protein (hsCRP) as measured in plasma at baseline, 1 hour into the dialysis session, at 4 hours at the end of the dialysis session, 2 hours after the dialysis session and at 24 hours after dialysis.
Timepoint [1] 238281 0
Plasma highly sensitive C reactive protein (hsCRP) will be measured at baseline, 1 hr into dialysis, at 4 hours at the end of dilalysis, 2 hours post dialysis and 24 hours post dilalysis. HsCRP is measured by standard laboratory assay.
Primary outcome [2] 238282 0
Inflammatory cytokines (tumor necrosis factor (TNF), interleukin 6 (IL6)) will be measured at baseline, 1 hr into dialysis, at 4 hours at the end of dilalysis, 2 hours post dialysis and 24 hours post dilalysis..Cytokines measured by enzyme linked immunoabsorbent assay (ELISA).
Timepoint [2] 238282 0
Inflammatory cytokines will be measured at baseline, 1 hr into dialysis, at 4 hours at the end of dilalysis, 2 hours post dialysis and 24 hours post dilalysis.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants were recruited from the dialysis service.
Patients were randomly assigned to receive either dialysis with a continuous insulin infusion or to a conventional dialysis session and then subsequently switched over to the opposite treatment, with at least one week between each study. Allocation was concealed with a third party off site advising the dialysis nurses which treatment option was allocated.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization was achieved by use of a computerized randomization plan generator (www.randomization.com).
Masking / blinding
Blinded (masking used)
