E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to compare the effect of N-acetylcysteine (NAC) intravenously administered at each dialysis session (2gram on 3 dialysis sessions per week) to placebo on circulating tissue factor (FT) levels in patients with Chronic Kidney Disease on chronic terminal in hemodialysis after 4 weeks of treatment. The objective is to show a 33% decrease in circulating FT levels in the NAC group compared to the control group |
L’objectif principal est de comparer l’effet que la N-acétylcystéine (NAC) administrée par voie intra veineuse à chaque séance de dialyse (2grammes sur les 3 séances de dialyse par semaine) par rapport au placebo sur les taux de facteur tissulaire (FT) circulant chez les patients insuffisants rénaux chroniques terminaux en hémodialyse chronique après 4 semaines de traitement. l'objectif est de montrer une diminution de 33% du facteur tissulaire circulant dans le groupe NAC comparé au groupe contrôle. |
|
E.2.2 | Secondary objectives of the trial |
To compare pro-coagulant activity and plasma tissue factor expression between the two groups
To compare the rate of erythrocyte GSH between the two groups
To compare the expression of circulating tissue factor after a hemodialysis session between the two groups |
Comparer l’activité pro coagulante et l'expression du facteur tissulaire plasmatique entre les deux groupes
Comparer le taux de GSH érythrocytaire entre les deux groupes
Comparer l’expression du facteur tissulaire circulant après une séance d’hémodialyse entre les deux groupes |

E.5 End points |
E.5.1 | Primary end point(s) |
The circulating tissue factor is measured by ELISA test from the plasma from a blood sample of a 4.5ml citrate tube. The objective of this measure will be to observe a reduction of one third of the rate between the beginning of the treatment and the end of the treatment being 4 weeks. Plasma Circulating Tissue Factor Levels are correlated with Cardiovascular Mortality |
La mesure du facteur tissulaire circulant s’effectue par test ELISA à partir du plasma provenant d’un prélèvement sanguin d’un tube citraté de 4,5ml. L’objectif de cette mesure sera d’observer une diminution d’un tiers du taux entre le début du traitement et la fin du traitement soit 4 semaines. Les taux plasmatiques de facteur tissulaire circulant sont corrélés avec la mortalité cardio-vasculaire |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
The measurement of the tissue coagulant activity test is carried out by activated factor X generation test (fluorometric measurement) from citrated plasma (one tube). measuring the effectiveness of treatment on leukocyte tissue factor, involved in the thrombosis process. |
La mesure du test d’activité pro coagulante du facteur tissulaire s’effectue par test de génération de facteur X activé (mesure fluorimétrique) à partir de plasma citraté (un tube). mesure de l'éfficacité du traitement sur le facteur tissulaire leucocytaire, impliqué dans le processus de thrombose. |
