This preliminary case-control study assessed oxidative stress in 40 women with histologically confirmed endometrioma versus 40 women without laparoscopically confirmed endometriosis by measuring plasma native thiol, total thiol, and disulfide using a fully automatic Erel method for dynamic thiol/disulfide homeostasis, alongside Ca-125, ESR, and CRP. Women with endometrioma had significantly decreased native and total thiol levels and significantly increased disulfide values and higher disulfide/thiol ratios compared with controls, with a positive correlation between native thiol levels and r-ASRM stage. The authors explicitly characterize the work as preliminary. This paper is centrally about endometriosis — it evaluates dynamic thiol/disulfide homeostasis as oxidative stress markers in cases with endometrioma.

Abstract

Objective: This preliminary study aims to use "dynamic thiol/disulfide homeostasis" with the new Erel method to evaluate the effect of oxidative stress in patients with endometrioma. Material and Method: The study group consisted of 40 cases with histologically confirmed endometrioma, and 40 women with no laparoscopically confirmed endometriosis were taken as the control group. Plasma thiol, total thiol (TT), and disulfide (SS) levels were measured with the new, fully automatic method described by Erel and Neselioglu. Serum Ca-125, sedimentation (Sed), C-reactive Protein (CRP), and thiol/disulfide levels were measured. The two groups' plasma thiol, total thiol, and disulfide levels were compared, and the relation between thiol/disulfide homeostasis and stage of the endometriosis, Ca-125, Sed, and CRP was evaluated. Results: In cases with endometrioma, disulfide/native thiol (3,12±2,02, 2,05±1,21, p=0,005) and disulfide/total thiol ratios (3,50±2,52, 2,22±1,36, p=0,006) were significantly increased, native thiol (469,30±126,52, 571,72±125,32 p=0,00) total thiol levels (505,17 ± 133,88, 603,0±134,22 p=0,02) were significantly decreased when compared with the control group. There was a positive correlation between native thiol level and revised American Society for Reproductive Medicine Classification (r-ASRM) (p=0,041). Conclusion: As expected, "dynamic thiol/disulfide homeostasis" with the new Erel method, the significant decrease in total thiol and native thiol levels, which are used as oxidative stress markers, and the increase in disulfide values demonstrated by this study support the hypothesis that oxidative stress plays a role in endometriosis and these markers can be used in the management of endometriosis

Abstract

Objective: This preliminary study aims to use "dynamic thiol/disulfide homeostasis" with the new Erel method to evaluate the effect of oxidative stress in patients with endometrioma.

Material

and Method: The study group consisted of 40 cases with histologically confirmed endometrioma, and 40 women with no laparoscopically confirmed endometriosis were taken as the control group. Plasma thiol, total thiol (TT), and disulfide (SS) levels were measured with the new, fully automatic method described by Erel and Neselioglu. Serum Ca-125, sedimentation (Sed), C-reactive Protein (CRP), and thiol/disulfide levels were measured. The two groups' plasma thiol, total thiol, and disulfide levels were compared, and the relation between thiol/disulfide homeostasis and stage of the endometriosis, Ca-125, Sed, and CRP was evaluated.

Results

In cases with endometrioma, disulfide/native thiol (3,12±2,02, 2,05±1,21, p=0,005) and disulfide/total thiol ratios (3,50±2,52, 2,22±1,36, p=0,006) were significantly increased, native thiol (469,30±126,52, 571,72±125,32 p=0,00) total thiol levels (505,17 ± 133,88, 603,0±134,22 p=0,02) were significantly decreased when compared with the control group. There was a positive correlation between native thiol level and revised American Society for Reproductive Medicine Classification (r-ASRM) (p=0,041).

Conclusion

As expected, "dynamic thiol/disulfide homeostasis" with the new Erel method, the significant decrease in total thiol and native thiol levels, which are used as oxidative stress markers, and the increase in disulfide values demonstrated by this study support the hypothesis that oxidative stress plays a role in endometriosis and these markers can be used in the management of endometriosis Downloads Article Details This work is licensed under a Creative Commons Attribution-NonCommercial 4.0 International License.
