Abstract

The existence of oxidative stress in uremia is well proved but the relative importance of uremic status versus the role of free iron in exacerbating oxidative stress in patients with uremia is not been clarified. Serum creatinine, free iron both in ferrous and ferric state, protein thiols, lipid hydroperoxides levels were estimated by spectrophotometric methods. The study groups comprised of patients with chronic kidney disease on conservative management, on hemodialysis with and without iron supplementation, and compared with healthy controls. Free iron levels were higher in patients with chronic kidney disease on conservative management, hemodialysis patients with and without iron supplementation. Hemodialysis cases with iron supplementation had significantly higher free iron levels as compared to hemodialysis cases without iron supplementation. The levels of lipid hydroperoxides were higher and protein thiols were lower in patient groups. Creatinine correlated positively with free iron and lipid hydroperoxides, and negatively with protein thiols. In conclusion, uremia per se may be responsible for enhanced oxidative stress in patients with chronic kidney disease
