Abstract | OBJECTIVE: Increased cardiovascular risk in hemodialysis patients may be related to augmented oxidative stress and inflammation, for which no proven beneficial therapies are available. STUDY DESIGN: SETTING: Outpatient dialysis center. PATIENTS: MAIN OUTCOME MEASURES: Plasma concentrations of interleukin-6 (IL-6) and protein carbonyl content were determined by enzyme-linked immunosorbant assay. C-reactive protein was measured by nephelometry. The F(2) isoprostanes were measured by gas chromatography-mass spectrometry. Erythrocyte DHA content was measured by gas chromatography. RESULTS: Sixty-three patients were enrolled, and 57 completed the study. No serious adverse events were attributed to either active treatment or placebo. In the treatment group, but not in the placebo group, there were significant decreases in IL-6 (21.4 +/- 3.5 to 16.8 +/- 3.7 pg/mL), white blood cell (WBC) count (7.4 +/- 0.3 to 6.9 +/- 0.4 10(3)/microL), and neutrophil fraction of WBCs (4.8 +/- 0.3 to 4.4 +/- 0.3 10(3)/microL), at P < .05 for all. There were no significant changes in plasma concentrations of CRP, F(2) isoprostanes, or carbonyls in either group. CONCLUSION:
