An Association Between the Intestinal Permeability Biomarker Zonulin and the Development of Diabetic Retinopathy in Type II Diabetes Mellitus.
Objectives: Increased intestinal permeability (IP) and gut microbiota dysbiosis have been implicated in low-grade chronic inflammation, which is an important factor in the pathogenesis of diabetic retinopathy (DR). This study aims to demonstrate the relationship between the IP biomarker zonulin and DR in patients with type 2 diabetes mellitus (T2DM).
Materials and methods: This study was conducted with a total of 89 T2DM patients, including 33 non-DR, 28 with non-proliferative DR (NPDR), and 28 with proliferative DR (PDR), and 32 healthy controls. Zonulin levels were determined from blood samples using an enzyme-linked immunosorbent assay kit.
Results: There was no difference between the four groups in terms of age (p=0.236), gender (p=0.952), and body mass index (p=0.134) of the participants. Zonulin levels were significantly higher in the PDR group compared to the other three groups, as well as in the non-DR and NPDR groups compared to the control group. In multivariate logistic regression analysis, zonulin was found to be an independent predictor of DR (odds ratio: 1,781, 95% confidence interval: 1,122-2,829, p=0.014).
Conclusion: Our study showed that elevated zonulin levels may play a significant role in the development of DR, particularly during the transition to the proliferative stage. This suggests that regulation of IP could be one of the targets of DR treatment. More studies are needed to determine whether a eubiotic gut microbiota and IP have a direct relationship with DR.
期刊介绍:
The Turkish Journal of Ophthalmology (TJO) is the only scientific periodical publication of the Turkish Ophthalmological Association and has been published since January 1929. In its early years, the journal was published in Turkish and French. Although there were temporary interruptions in the publication of the journal due to various challenges, the Turkish Journal of Ophthalmology has been published continually from 1971 to the present. The target audience includes specialists and physicians in training in ophthalmology in all relevant disciplines.
