Summary

Current hemodialysis techniques fail to efficiently remove protein-bound uremic toxins (such as p-cresyl sulfate (p-CS) or indoxyl sulfate (IS)) due to their strong binding to serum albumin. The accumulation of these toxins in end-stage renal failure patients on hemodialysis is strongly suspected to contribute to the significant morbidity and mortality observed in this population.

Pre-clinical studies conducted previously showed that medium-chain fatty acids (such as sodium octanoate and decanoate), which are natural ligands of albumin, can effectively displace the binding of uremic toxins on serum albumin and thus promote their elimination during a hemodialysis session.

Medialipide® 20% (Braun) is an emulsion of medium chain triglycerides (MCT) (6 to 12 carbons) used in parenteral nutrition. Medialipide® constitutes a relevant clinical formulation for the administration of octanoate and decanoate because it contains 94% of sodium octanoate and decanoate.

In this study, a proof of concept intervention will be carried out to study the effect on the clearance uremic toxins clearance of the perfusion of Medialipide® emulsion (as a sodium octanoate and decanoate donor) in patients during their hemodialysis session compared to a control situation Sodium chloride (NaCl) 0,9%).

Conditions

Interventions

DRUG

Medialipide 20% perfusion

Each patient will receive during a 4 hours hemodialysis session a perfusion of Medialipide 20% at a rate of 0,11 g/kg/h. Medialipide will be perfused using the venous line connected to the hemodialysis machine.

DRUG

NaCl 0,9%

Each patient will receive during a 4 hours hemodialysis session a perfusion of NACL 0,9% with a volume corresponding to the one of Medialipide 20%. NaCl 0,9% will be perfused using the venous line connected to the hemodialysis machine.

BIOLOGICAL

Blood sample

Serial biological sampling for the measurement of different blood concentrations : electrolytes, serum protein , albumin, renal function (urea, creatinine), hemoglobin, hematocrit, liver test, lipid test, ketone bodies, 6 uremic toxins (including IS and p-CS), sodium octanoate and decanoate.
