Trace Elements Concentration in Dialysis (EMTDialyse)

September 9, 2021 updated by: Assistance Publique - Hôpitaux de Paris

In hemodialysis population the study team finds high concentrations of toxic trace elements (2 times higher than the general population for cadmium 4 to 13 times for lead). Several recent studies suggest a role of chronic exposure to cadmium in the loss of residual renal function, osteoporosis, graft failure, arteriosclerosis, as well as in excess cardiovascular mortality.

Moreover, in hemodialysis population, a deficit of certain essential trace elements (manganese, selenium, zinc) is observed. For example, in the population undergoing chronic hemodialysis, a zinc deficiency is found in 40 to 78% of cases. Zinc is a cofactor of more than 70 enzymes.

In this observational cohort, the study team seeks to understand the impact of HD and HDF on the serum concentrations of heavy metals and also oligometals, by studying their concentrations in the dialysate during dialysis sessions by inductive coupled plasma mass-spectrometry (ICP-MS).

Detailed Description

Primary objective: Evaluate the trace element concentration (heavy metals Cd and Pb and oligometals: Fe, Zn, Cu, Mn and also Se) in the dialysate before and during dialysis session. By studying the variation in concentration between the initial concentration of trace element in the dialysis fluid and the final concentration after membrane in the dialysate (waste pipe).

Method : Prospective study, in dialysis population, inclusion period will be from September 1, 2021 to January 31, 2022, in Ambroise Paré hospital, Paris, France. Duration of follow-up will be 1 day.

Dialysate samples will be taken in the venous injection site before connecting the patient, at 0 and 10 minutes after disinfection.

After connecting the patients, post-membrane dialysis sample (waste pipe) will be taken at 30, 60, 120 and 180minutes. Trace element dosage will be done by ICP-MS.
