We investigated the role of serum uric acid (sUA) and superoxide dismutase (SOD) as predictive factors for mortality in hemodialysis (HD) patients. 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. sUA among survivors (112.1 +/- A 13.82 mu mol/L) was significantly lower than in deceased (160.8 +/- A 16.81 mu mol/L, p lt 0.001), while SOD was higher in survivors (31.8 +/- A 6.61 kU/L) than among deceased (20.2 +/- A 3.03, p lt 0.05). Kaplan-Meier survival curves showed the greatest mortality risk in the highest tertile of basal sUA concentration (a parts per thousand yen127.11 mu mol/L, p lt 0.001), and for SOD in the lowest tertile (a parts per thousand currency sign23.83 kU/L, p lt 0.05). Our results suggest that high sUA and low SOD may predict all-cause and cardiovascular mortality in HD patients.
