Özet

Amaç: Çalışmanın amacı yaşa bağlı ve diabetik katarakt gelişiminde muhtemel antioksidan sistem, lipid peroksidasyonu ve sialik asit ilişkisini araştırmak. Gereç ve Yöntem: Çalışmaya kan ve ön kamara sıvısı alınan 25 yaşa bağlı kataraktlı (grup 1), 25 diabetik kataraktlı (grup 2) hasta ve 24 eş yaşta sağlıklı kontrol grubu alınmıştır (grup 3). Serumda, sialik asit (SA), malondialdehit (MDA) konsantrasyonları, Katalaz (CAT) ve superoksit dismutaz (SOD) aktiviteleri, ön kamara sıvısında ise SA ve CAT aktiviteleri bakılmıştır. Bulgular: Grup 2 hastalarında serum SA ve MDA konsantrasyonları grup 1 (p 0.01). Ön kamara örneklerinde ise grup 2 hastalarında grup 1 ile karşılaştırıldığında yüksek ortalama SA konsantrasyonu ve düşük CAT aktivitesi tespit edilmiştir (p 0.01). Tartışma: Artmış oksidatif stres ve azalmış antioksidan enzim aktivitesinin yaşa bağlı ve diabetik katarakt gelişiminde rol oynadığını düşünmekteyiz.Artmış sialik asit seviyeleri ise katarakt gelişimi ile ilgili gözükmektedir.

Abstract

Purpose: To investigate the possible relationship of agerelated nuclear and diabetic cataract development with antioxidant system, lipid peroxidation and sialic acid levels in serum and aqueous humour. Materials and Methods: Blood and humour aqueous samples of 25 patients with age-related cataract (Group 1), 25 patients with diabetic cataract (Group 2), and 24 age-matched controls (Group 3) without cataract were included. Sialic acid (SA) and malondialdehyde (MDA) concentrations, and catalase (CAT) and superoxide dismutase (SOD) activities were detected in serum samples. Aqueous samples were analysed to detect only SA levels and CAT activity. Results: Group 2 patients had significantly higher serum SA and MDA concentrations as compared to group 1 (p<0.001 for both) and group 3 (p<0.0001, and p<0.001 respectively) and lower serum CAT and SOD activities than group 3 (p<0.001 and p<0.01 respectively). Serum CAT activity was also significantly lower in group 2 than group 1 (p<0.01), and SOD activities were not different between the groups 2 and 1 (p>0.05). In case of aqueous samples, group 2 patients had higher mean concentration of SA, and lower levels of CAT activity as compared to group 1 (p<0.001 for both) .Group 1 patients also had significantly decreased CAT activity when compared to group 3 (p<0.01). But SA levels were not different between groups 1 and 3 (p>0.05). Conclusions: Increased oxidative stress and decreased antioxidant enzyme activities may have a role in the development of age-related and diabetic cataract. Increased sialic acid levels seem to be associated with cataract development in diabetics.
