NCT01408680

Brief Summary

The investigators believe that relieving the oxidative stress experienced by hemodialysis patients may help improve cardiovascular health. In this study, the investigators hypothesize that administration of coenzyme Q10, as a targeted antioxidant therapy, will ameliorate the excessive oxidative stress experienced by hemodialysis patients. This will lead to improvements in biomarkers of:

  • oxidative stress status
  • inflammatory status
  • endothelial dysfunction

Outcome Measures

Primary Outcomes (3)

  • Change from Baseline in Oxidative Stress Status at 1 month

    We will examine whether administration of coenzyme Q10 will ameliorate the excessive oxidative stress burden as evidenced by changes in serum biomarkers of oxidative stress at the 1-month visit.

    1 month

  • Change from Baseline in Oxidative Stress Status at 2 months

    We will examine whether administration of coenzyme Q10 will ameliorate the excessive oxidative stress burden as evidenced by changes in serum biomarkers of oxidative stress at the 2-month visit.

    2 months

  • Change from Baseline in Oxidative Stress Status at 4 months

    We will examine whether administration of coenzyme Q10 will ameliorate the excessive oxidative stress burden as evidenced by changes in serum biomarkers of oxidative stress at the 4-month visit.

    4 months
