PURPOSE: To evaluate total antioxidant status (TAS) in the plasma of pseudoexfoliation glaucoma (PEG) patients and to compare this level with a matching control group. Additionally, we aim to investigate the effect of the combined action of the lysyl oxidase-like 1 (LOXL1) mutation status with TAS level on the development of PEG. METHODS: Plasma samples were obtained from 54 PEG patients and 54 controls of matching age, sex, and ethnicity. TAS in all samples was determined by spectrophotometric and enzyme-linked immunosorbent assay methods. The coding region of LOXL1, where it encompasses both single nucleotide polymorphisms (SNPs; rs1048661 and rs3825942), was sequenced. RESULTS: The mean (±SD) total antioxidant (TAS) value was lower among patients: 0.87 (0.24), range 0.9-1.41 than controls: 1.07 (0.23), range 0.72-1.94, and this difference was statistically significant (p<0.0001: 95%CI: -0.295-0.114). Evaluating the impact of age, sex, and the mutation in addition to the mean TAS value in patients with PEG, a logistic regression analysis was conducted using diseased/not diseased as the outcome of interest (the dependent variable). Results show that, controlling for all other variables, mean TAS value (p<0.0001) and the mutation G/G in rs3825942 (p=0.041) are significant risk factors for PEG. CONCLUSIONS: Our findings provide evidence that TAS decreases in the plasma of PEG patients, suggesting that TAS may have an important role in the pathogenesis of PEG. The combined effect of the "G" allele and the decreased TAS may contribute to the overall pathogenesis of PEG. |
