To determine the serum thiol disulfide homeostasis in patients with pseudoexfoliation (PEX) syndrome.
Thirty-five patients with PEX syndrome and forty healthy subjects were included in this observational case-control study. Serum native thiol, total thiol, disulfide, and native thiol/disulfide ratio were determined using a novel and automated assay.
The mean serum total thiol and native thiol levels were significantly lower in patients with PEX syndrome compared to healthy controls (p = 0.001). The mean serum disulfide level was significantly higher in patients with PEX syndrome compared to healthy controls (p = 0.023). The serum native thiol/disulfide ratio was lower in patients with PEX syndrome compared to healthy subjects (16 ± 10.1 vs 22.3 ± 11.5, respectively, p = 0.014).
Our findings provide evidence that the dynamic native thiol/disulfide ratio is lower in PEX syndrome, which shows a reduction in the natural cell reductive capacity reservoir.
确定假性剥脱（PEX）综合征患者的血清硫醇二硫键内稳态。
本观察性病例对照研究纳入了35例PEX综合征患者和40名健康受试者。使用一种新型自动化检测方法测定血清天然硫醇、总硫醇、二硫键以及天然硫醇/二硫键比值。
与健康对照相比，PEX综合征患者的血清总硫醇和天然硫醇平均水平显著降低（p = 0.001）。与健康对照相比，PEX综合征患者的血清二硫键平均水平显著升高（p = 0.023）。与健康受试者相比，PEX综合征患者的血清天然硫醇/二硫键比值更低（分别为16±10.1和22.3±11.5，p = 0.014）。
我们的研究结果表明，PEX综合征患者动态天然硫醇/二硫键比值较低，这表明天然细胞还原能力储备降低。
