Effect of oxidative stress on antioxidant enzyme activities, homocysteine and lipoproteins in chronic kidney disease

Our aim was to determine the association of paraoxonase (PON1), superoxide dismutase (SOD) and catalase (CAT) activities and malondialdehyde (MDA) concentration, with lipoprotein and homocysteine (Hcy) concentrations in chronic kidney disease (CKD). We examined 60 patients with CKD (35 men and 25 wo...

Zusammenfassung:Our aim was to determine the association of paraoxonase (PON1), superoxide dismutase (SOD) and catalase (CAT) activities and malondialdehyde (MDA) concentration, with lipoprotein and homocysteine (Hcy) concentrations in chronic kidney disease (CKD). We examined 60 patients with CKD (35 men and 25 women), aged 52.7 -/+ 3.1 years, and 60 age-, sex- and body mass index (BMI)-matched control subjects. Serum PON1 activity, levels of lipoproteins, Hcy and MDA were evaluated; SOD and CAT activities in erythrocytes were also investigated. Levels of MDA, lipoprotein (a) (Lp(a)) and Hcy were significantly higher, while PON1 activity was lower in CKD than in controls (p0.05). Levels of high-density lipoprotein cholesterol (HDL-C) and apolipoprotein A-I (ApoA-I) were lower in CKD than in controls (p
