Diurnal Variation of Uremic Solutes in Peritoneal Dialysis

May 12, 2016 updated by: Universitaire Ziekenhuizen KU Leuven

Diurnal Variation of Mineral Metabolism and Protein Fermentation Metabolites in Peritoneal Dialysis Patients and Healthy Volunteers

Study on the daytime variation of uremic retention solutes and markers of bone-mineral metabolism in patients with end-stage kidney disease treated with peritoneal dialysis

Study Overview

Status

Completed

Detailed Description

Many epidemiological studies have pointed to the association between serum parameters of phosphate metabolism (phosphate, FGF23) and microbiotic protein fermentation (p-cresyl sulphate [PCS], indoxyl sulphate [IS]) on the one hand and increased risk of all-cause and cardiovascular death on the other hand.

Hypothesis: Due to failing feed-back mechanisms, diurnal variation of serum concentrations of serum phosphate and fermentation metabolites will be more pronounced in dialysis patients, especially in those with negligible residual kidney function.

Clinical studies assessing this issue are scarce to non-existing.
