Purpose: We investigated the role of serum uric acid (sUA) and superoxide dismutase (SOD) as predictive factors for mortality in hemodialysis (HD) patients. Methods: SOD, butyrylcholinesterase, and malondialdehyde were estimated spectrophotometrically and the other parameters by standard procedures. High-sensitive C-reactive protein was assayed by a sandwich ELISA method. Results: sUA among survivors (112.1 ± 13.82 μmol/L) was significantly lower than in deceased (160.8 ± 16.81 μmol/L, p < 0.001), while SOD was higher in survivors (31.8 ± 6.61 kU/L) than among deceased (20.2 ± 3.03, p < 0.05). Kaplan-Meier survival curves showed the greatest mortality risk in the highest tertile of basal sUA concentration (≥127.11 μmol/L, p < 0.001), and for SOD in the lowest tertile (≤23.83 kU/L, p < 0.05). Conclusion: Our results suggest that high sUA and low SOD may predict all-cause and cardiovascular mortality in HD patients. © 2012 Springer Science+Business Media, B.V.
