Evaluation of the Dialyzer Vitamin E Coated Effect Inflammatory State of Patients in ESRD and Its Clinical Benefits in Terms of Anemia

Coordinator : Pr JP.CRISTOL Montpellier hospital university Rational : The hemodialyzed patients are subject to inflammation due to their pathologies and to the technique. The VIE dialyzer polysulfon coated to vitamin E has been shown to have a favourable action on inflammation and anemia. The investigators want to highlight the influence of vitamine E graft using as controlled dialyzer a similar polysulfon from the same manufacturer without vitamin E.

Medical device : ViE High flux dialyzer -> vitamin E coated polysulfone membrane manufactured by Asahi Kasei Medical, with CE mark and intended for use in hemodialysis for the patient suffering from acute or chronic renal failure Controlled medical device : Leoceed H high flux dialyzer : polysulfone membrane manufactured by Asahi Kasei Medical, with CE mark and intended for use in hemodialysis for patient suffering from acute or chronic renal failure Objectives : To assess the benefits of a vitamin E coated polysulfone membrane on the micro-inflammatory state of chronic dialysis patients Primary end point : Evolution of the well-known inflammatory marker : High sensibility-CRP Secondary end point : Evolution of the following inflammatory markers : IL-6, TNFa, fibrinogen, antibodies anti- LDLox Evolution of Hemoglobin and ERI Evolution of Nutritional parameters : albumin and pre albumin Study design : Prospective multicenter controlled and randomized protocol study Duration : 12 months Number of patients : 120 patients : 60 patients per group 120 patients : 60 patients per group Adult ESRD patient, whatever the origin, treated by HD, thrice a week for about 4 hours and hemo dynamically well balanced Inclusion criteria : Dialyzed patient on synthetic high flux dialyzer for 3 months Patient with a vascular access allowing a blood flow rate ≥ 250 ml/min Patient with micro inflammation, i.e an average CRP between 5 and 20 mg/L on the two last check-up of CRP Patient informed of the study and having signed the inform consent. Exclusion criteria : Underage patient Subjects who are pregnant or planning to become pregnant during the study Patient with an infection influencing the Hb level
