Oxidative Stress and Nucleic Acid Oxidation in Patients with Chronic Kidney Disease

Table 2

Antioxidant therapies to reduce oxidative stress in CKD and HD patients.

StudyIntervention SubjectsEffect

Vitamin E
Boaz et al. (2000) [45]
SPACE study
High-dose alpha-tocopherol (800 IU once daily) or placebo 196 HD patients with preexisting cardiovascular disease followed for a median of 519 days(1) Significant reduction in myocardial infarctions and other cardiovascular events
(2) No significant difference in overall survival
Mann et al. (2004) [46]
HOPE study
Vitamin E, 400 IU once daily993 patients with mild-to-moderate renal insufficiency at high risk for cardiovascular eventsNo apparent effect on cardiovascular outcomes

Acetylcysteine
Tepel et al. (2003) [47]Acetylcysteine, 600 mg twice daily 134 HD patients followed for 2 years(1) Cardiac events reduced by 30% (2) Ischemic stroke reduced by 36%

Vitamin C
Tarng et al. (2004) [48]Vitamin C, 300 mg three times weekly for 8 weeks60 HD patientsMean 8-OH-dG levels decreased significantly in all subjects

Losartan
Kayabasi et al. (2013) [49]Losartan 50–100 mg once daily52 HD patients followed for 3 monthsDecreasing oxidative stress index and increasing plasma thiol groups

Folic acid
Delfino et al. (2007) [50]Folic acid, 10 mg three times weekly for 6 months46 HD patients Effectively lowered plasma Hcy levels

Bardoxolone methyl
Pergola et al. (2011) [51]
BEAM study
Bardoxolone methyl at a target dose of 25, 75, or 150 mg once dailyAdults with CKD Improved estimated glomerular filtration rate at 24 weeks
