In this study, the effect of GCT on the thiol/disulfide balance was investigated. Methods: One-hundred women that underwent a 50 g GCT at 24–28 weeks of gestation (63 positive and 37 negative results) were evaluated in terms of thiol/disulfide in serum samples at test hours 0 and 1. Results: Compared to the baseline values (hour 0), after the glucose load (hour 1), the thiol and native thiol/total thiol (p &lt; 0.0001) of the GCT-positive women were reduced whereas the values of glucose, disulfide, disulfide/native thiol, disulfide/total thiol (p &lt; 0.0001) and total thiol increased (p = 0.018). Conclusion: In GCT-positive pregnant individuals, the glucose load increases oxidative stress by changing the thiol/disulfide homeostasis. Such an effect is not observed in healthy pregnancies. © 2018, © 2018 Taylor &amp; Francis Group, LLC.</dc:description><dc:publisher>Taylor and Francis Ltd</dc:publisher><dc:date>2018</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/ebyu/14308</dc:identifier><dc:identifier>https://doi.org/10.1080/15513815.2018.1453002</dc:identifier><dc:identifier>1551-3815</dc:identifier><dc:language>en</dc:language><dc:relation>Fetal and Pediatric Pathology</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/14308</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
