Abstract

Introduction: The role of oxidative stress and antioxidant capacity in the development of endometrial hyperplasia (EH) is controversial. Aim: The study aimed to evaluate Thiol/disulfide Homeostasis and ischemia modified albumin (IMA) levels in patients with EH without atypia. Materials and Methods: In this prospective case-control study, patients with EH without atypia (HP group) (n=28), patients with nonhyperplasia (proliferative/secretory/irregular proliferative/irregular secretory endometrium) (non-HP group) (n=28), and 28 healthy women (control group) were included. The patient's clinical characteristics, serum Thiol/disulfide parameters, and IMA levels were compared between groups. Results: A total of 84 patients were included in the study. Patients’ mean age, BMI, and mean native thiol (-SH-), total thiol (-SH-+-SS-), disulfide (-SS-), and IMA levels were similar among the three groups. The -SS- /-SH- ratio was higher in the HP group than the non-HP group. -SS- /-SH-+-SS- ratio was higher in the HP group vs. the other two groups. The -SS- /-SH-+-SS ratio was higher in the HP group vs. the non-HP group. -SH-/ -SH-+-SS- ratio was lower in the HP group than in the non-HP group. ET was greater in the HP group than in the non-HP and control groups. ET was also significantly greater in the non-HP group vs. in the control group. -SS-/-SH- ratio was found to be predictive with 64% sensitivity and 68% specificity for EH (area under curve = 0.672, p = 0.01). Conclusion and Suggestions: The dynamic thiol/disulfide balance shifted to the disulfide side in women with endometrial hyperplasia.
