Body Composition Monitor Among Daily Home Dialysis With Low Flow Dialysate

The fluid overload measured by the Body Composition Monitor (BCM Fresenius Medical Care) is a new independent risk factor of mortality. This risk has already been described in intermittent hemodialysis patients and peritoneal dialysis patients but never evaluated in Daily Home Dialysis with low dialysate flow. The investigator propose a first study measuring the state of hydration by impedancemetry (BCM) in this population. The aim of this work is to to analyze hydration status in a representative sample of prevalent Daily Home Dialysis with low-flow Dialysate patients. Secondary objectives are to identify associations between hydration status and patient characteristics and treatment practice in order to find out which conditions should alert the clinician to potential fluid overload, to compare these results with the peritoneal dialysis population and in center hemodialysis population, to evaluate the correlation between impedancemetry and blood pressure in this population, to assess the nutritional status and evaluation of a new method of measurement of kt / V based on impedancemetry, without recourse to a blood test.
