PURPOSE: To compare plasma levels of sirtuin 1 (SIRT1) and adiponectin (APN) in patients with primary open-angle glaucoma (POAG), exfoliative glaucoma (XFG), and healthy control subjects. METHODS: This prospective case-control study collected plasma samples from 118 participants. All subjects underwent a comprehensive ophthalmologic examination before the acquisition of a plasma sample. Plasma samples were obtained from 40 POAG, 38 XFG, and 40 healthy control subjects without any evidence of systemic or ocular disease. Serum SIRT1 and APN levels were estimated by an enzyme-linked immunosorbent assay, ELISA (Elabscience, Houston, USA) method. Statistical analysis of results relied on Kolmogorov-Smirnov, Kruskal-Wallis, Chi-square, analysis of variance (ANOVA) tests, and linear regression analysis, where appropriate. RESULTS: A significant decrease in SIRT1 levels was observed in POAG patients compared to healthy controls (p = 0.004, Dunn's test). In contrast, no difference was detected between XFG and POAG patients or healthy controls (p = 0.32 and p = 0.34, respectively, Dunn's test). There was no significant difference in plasma APN levels between the three groups under investigation (p = 0.59, ANOVA). CONCLUSION: Alterations in serum level of SIRT1 may suggest a possible role in POAG via potential effects in neuroprotection and oxidative stress.
