Redox State in the Course of Chronic Renal Insufficiency and Hemodialysis: Implications in Morbimortality


The influence of hemodialysis on oxidative stress, endothelial activation, inflammation and on the redox state of lymphocytes should be clarified as well as the putative relationships between all these parameters.

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Non-Randomized
    • Intervention Model: Parallel Assignment
    • Masking: None (Open Label)
  • Study Primary Completion Date: April 2012

Detailed Description

Up to now, no anti-oxydative treatment has been able to reduce the mortality of the patients with Kidney Failure. Thus it is necessary to have a better knowledge of oxydative stress mechanisms in patients with KF in order to find more efficacious treatments. The influence of hemodialysis upon oxidative stress is not well known.

Clinical Trial Outcome Measures

Primary Measures

  • This study should allow to clarify the redox state some plasma by quantification of thiols membranous on the surface of lymphocytes at the hemodialysis and insufficient renal chronic not dialysed patients.
    • Time Frame: 48 months

Secondary Measures

  • This study should allow to estimate in a forward-looking longitudinal plan the possible involvement of the parameters of the redox state and the morbidity and the cardiovascular and global mortality in 2 years in 2 studied populations.
    • Time Frame: 48 months
