Abstract

Objectives: To evaluate serum levels of zonulin and interleukin 6 (IL-6) in type 2 diabetes mellitus (T2DM) patients complicated by diabetic retinopathy and to investigate the effect of intestinal permeability on diabetic retinopathy (DR) progression. Materials and Methods: Eighty-nine patients with T2DM and 30 healthy controls aged between 18 and 80 years were enrolled. T2DM patients were grouped as without DR (n=30), with non-proliferative DR (n=29), and with prolif erative DR (n=30). Serum zonulin and IL-6 levels were measured with the ELISA method. Results: Zonulin levels showed no statistical difference by pairwise comparisons of groups, but IL-6 levels were significantly increased in non-proliferative and prolifera tive DR groups compared to the HC and without DR groups. Zonulin level was correlated with body mass index and IL-6 level; IL-6 level was correlated with duration of diabetes, fasting blood glucose and HbA1c. While duration of diabetes and serum IL-6 levels had an independent effect on DR development, zonulin had no effect. Conclusions: Serum zonulin levels cannot be used as a biomarker for the progression of the diabetic retinopathy complication.

Özet

Amaç: Diyabetik retinopati komplikasyonuna sahip tip 2 diyabetes mellitus (T2DM) hastalarında serum zonulin ve interlökin 6 (IL-6) düzeylerini değerlendirmek ve bağırsak geçirgenliğinin diyabetik retinopati (DR) ilerlemesi üzerindeki etkisini araştırmaktır. Gereç ve Yöntem: 18 ile 80 yaş aralığında T2DM hastalığına sahip 89 kişi ve 30 sağlıklı kontrol çalışmaya dahil edildi. T2DM hastaları DR bulunmayan (n=30), proliferatif olmayan DR (n=29) ve proliferatif DR (n=30) olarak gruplandırıldı. Serum zonulin ve IL-6 seviyeleri ELISA yöntemi ile ölçüldü. Bulgular: Zonulin düzeyleri, grupların ikili karşılaştırma larında istatistiksel bir fark göstermezken; IL-6 düzeyleri, sağlıklı kontrol ve DR bulunmayan gruplara kıyasla proli feratif olmayan ve proliferatif DR gruplarında önemli ölçüde arttı. Zonulin düzeyi, vücut kitle indeksi ve IL-6 seviyesi ile korelasyon mevcut iken IL-6 düzeyi diyabet süresi, açlık kan şekeri ve HbA1c ile korelasyon mevcuttu. Diyabet süresi ve serum IL-6 düzeylerinin DR gelişimi üzerinde bağımsız bir etkiye sahip olduğu, zonulinin etkisi olmadığı gözlenmiştir. Sonuç: T2DM’ta diyabetik retinopati komplikasyonunun ilerlemesi için serum zonulin düzeylerinin bir biyobelirteç olarak kullanılamayacağı sonucuna varıldı.
