Abstract

Abstract: We aimed to evaluate maternal serum thiol/disulphide homeostasis in pregnancies complicated by fetal distress (FD). A total of 100 patients beyond the 34th week of pregnancy were included in this study, and they were divided into two groups. The study group included 50 patients who had been diagnosed with FD; the control group was composed of 50 patients who had shown no signs of FD and who had undergone an elective (previous) caesarean section (CS). The native thiol, total thiol and native thiol/total thiol (%) concentrations were lower in Group 1 patients than Group 2 patients ( p < .001). The disulphide, disulphide/native thiol (%) and disulphide/total thiol (%) concentrations were higher in Group 1 patients than Group 2 patients ( p < .001). This study suggests that maternal thiol/disulphide homeostasis is impaired in pregnancies complicated by FD. IMPACT STATEMENT: What is already known about this subject? Oxidative stress (OS) has previously been investigated in FD. This study reports for the first time a new novel and automatic measurement method. What do the results of this study add? This study shows that the thiol balance shifts in the direction of disulphide in the cases of FD. What are the implications of these findings for clinical practice and further research? Thiol balance can be used for the timely diagnosis of FD.
