Abstract

Purpose: Chronic renal failure (CRF) is associated with numerous complications (atherosclerosis and related cardiovascular disturbances), which may partly result from increased oxidant stress and/or decreased antioxidant activity. The aim of this study was to investigate whether hemodialysis patients with advanced CRF have increased lipid peroxidation (LP) in plasma and red blood cells (RBC) and to evaluate the activity of the antioxidant enzymes (superoxide dismutase-SOD and glutathione peroxidase- GPx) in RBC and serum. Methods: We measured the erythrocyte and plasma malondialdehyde (MDA) levels that reflecting, the lipid peroxidation and the erythrocyte and serum GPx and erythrocyte SOD enzyme activities that reflecting the antioxidant protection system in 52 CRF patients having hemodialysis treatment and in 40 controls. Results: For CRF group both plasma and erythrocyte MDA leves were significantly higher compared to controls (p<0.001). Whereas both serum and eryhtrocyte SOD and GPx were significantly lower for CRF group compared to controls (p<0.001). Conclusion: According to results of this study oxidative stress is increased and antioxidant enzyme activities are decreased in hemodialysis patients, these alterations should be considered in the treatment of these patients.

Özet

Amaç: Kronik böbrek yetmezliği (KBY) oksidan stres artışı ve/veya antioksidan aktivitenin azalması nedeniyle gelişebilen çeşitli komplikasyonlarla (ateroskleroz ve kardiyovasküler bozukluklar) birliktedir. Bu çalışmada ileri kronik böbrek yetmezlikli hemodiyaliz hastalarında lipid peroksidasyonu artışı olup olmadığını araştırmak ve antioksidan enzim aktivitelerini değerlendirmek amaçlandı. Gereç ve Yöntem: Hemodiyaliz tedavisi gören 52 KBY hastası ve 40 sağlıklı kontrol grubunda; lipid peroksidasyonunun bir göstergesi olan malondialdehit (MDA) eritrosit ve plazma düzeyleri, antioksidan savunma sisteminin göstergeleri olan enzimlerden glutatyon peroksidaz'ın (GPx) eritrosit ve serum, süperoksit dismutaz'ın (SOD) eritrosit aktiviteleri ölçüldü. Bulgular: KBY hasta grubunda, hem plazma hem de eritrosit MDA seviyelerinin kontrol grubuna göre önemli oranda arttığı görüldü (p<0.001). Bununla beraber KBY grubunda, hem serum hemde eritrosit SOD ve GPx düzeyleri kontrol grubuna göre anlamlı ölçüde azaldığı tespit edildi (p<0.001). Sonuç: Bu çalışman sonucunda, hemodiyaliz hastalarında oksidatif stresin önemli ölçüde arttığı buna karşın antioksidan enzim aktivitelerinde azalma olduğu ve bu durumun tedavide dikkate alınması gerektiği kanaatine varıldı.
