Özet

Objective: Oxidative stress may change cellular function in multiple pathological conditions, including osteoporosis. We aimed to determine malondialdehyde (MDA) levels, advanced oxidation protein pruducts (AOPP), levels end products of protein oxidation, thiol as known antioxidant, serum paraoxonase 1 (PON1) activities as known lipid antioxidant, induced by reactive oxygen species (ROS) for evaluating oxidative stress in osteoporotic patients. Methods: 59 patients diagnosed with postmenopaual osteoporosis were included in the study and compared with 21 healthy controls. Serum AOPP, MDA, thiol levels and PON1 activity were measured according to an enzymatic spectrophotometric method. Results: The serum MDA, AOPP, and thiol levels was significantly higher in the patient group than controls (p<0.05). PON1 activity was found lower in the patients group than the control group. Conclusion: Increased ROS levels in osteoporotic patients may result in a pro-oxidation environment, which in turn could result in increased MDA, AOPP. As a result, lipid peroxidation and protein oxidation may have a role in the pathogenesis of the osteoporotic patients.

Abstract

Amaç: Oksidatif stres, osteoporozu da içeren pek çok patolojik durumda hücresel fonksiyonları değiştirebilir. Biz bu çalışmada postmenopozal osteoporozlu hastalarda oksidatif stresi değerlendirmek için, reaktif oksijen türleri (ROS) ile indüklenen lipid peroksidasyonu son ürünü malondialdehit (MDA), protein oksidasyonu son ürünü ileri düzey protein oksidasyonu ürünleri (AOPP), antioksidan olarak bilinen Thiol, lipid antioksidanı olarak bilinen serum paraoksonaz 1 (PON 1) aktivitesini belirlemeyi amaçladık. Yöntemler: Bu çalışmaya postmenopozal osteoporoz tanısı konan 59 hasta alındı. 21 sağlıklı kontrol grubuyla karşılaştırması yapıldı. Serum AOPP, MDA, thiol düzeyleri ve PON 1 aktivitesi enzimatik spektrofotometrik metotla ölçüldü. Bulgular: Serum MDA, AOPP ve thiol seviyeleri kontrol grubuna göre hastalarda istatistiksel olarak anlamlı derecede yüksekti (p<0,05). PON 1 aktivitesi kontrol grubuna göre hasta grubunda düşük bulundu. Sonuç: Osteoporozlu hastalarda artmış ROS düzeyleri prooksidan bir durum oluşturarak, AOPP, MDA düzeylerinin yükselmesine neden olur. Sonuç olarak lipid peroksidasyonu ve protein oksidasyonu osteoporoz patogenezinde rol oynayabilir.
