    The role of dynamic thiol/disulfide homeostasis for the evaluation of oxidative stress in endometriosis patients
    (MARMARA UNIV, FAC MEDICINE, 2022-01-01) Topbas Selcuki, Nura Fitnat; Yalcin Bahat, Pinar; Kaya, Cihan; Neselioglu, Salim; Bagci, Kubra; Goksu, Mustafa; Kabakci, Merle; Erel, Ozcan
    Objective: To evaluate the role of oxidative stress in endometriosis patients by determining dynamic thiol/disulfide homeostasis and ischemia modified albumin (IMA) levels. Patients and Methods: This prospective case-controlled study was conducted at a tertiary gynecology clinic in Istanbul, Turkey. 86 patients previously diagnosed with endometriosis and persistent endometriomas were included in the study group. 60 patients who visited the clinic during the study period for routine gynecological control were included in the control group. Thiol/disulfide parameters and IMA levels were determined from the serum samples. Results: When the thiol/disulfide parameters were compared between the study and the control group no significant difference was observed (p=0.49). Mean disulfide level in the control group was 18.58 +/- 5.73 mu mol/L, and in the study group was 18.61 +/- 7.37 mu mol/L. Levels were statistically similar in both groups (p=0.98). In addition, there were no differences between the groups in terms of IMA and albumin levels. Conclusion: The results of this study revealed no significant difference in the dynamic thiol/disulfide homeostasis among the endometriosis patients. Although, it has been accepted as a potential oxidative stress marker in other chronic inflammatory diseases, its use in determining the systemic oxidative stress level in endometriosis patients is limited.

    Laparoscopic endometrioma resection increases peri-implantation endometrial HOXA-10 and HOXA-11 mRNA expression
    (ELSEVIER SCIENCE INC, 2015-01-01) Celik, Onder; Unlu, Cihat; Otlu, Baris; Celik, Nilufer; Caliskan, Eray
    Objective: To determine whether laparoscopic endometrioma resection alters peri-implantation endometrial HOXA-10, HOXA-11, LIF, ITGB3 and ITGAV mRNA expression. Design: Case-control study. Setting: Medical school. Patient(s): Twenty infertile patients with uni-or bilateral endometrioma, five infertile patients having nonendometriotic benign ovarian cyst, and five fertile control subjects. Intervention(s): Mid-luteal-phase endometrial sampling was performed at the time of surgery. Second endometrial biopsies were obtained 3 months after laparoscopic endometrioma resection during the mid-luteal phase of the cycle. Main Outcome Measure(s): Endometrial HOXA-10, HOXA-11, LIF, ITGAV, and ITGB3 mRNA expressions were evaluated with the use of reverse-transcription polymerase chain reaction. Result(s): Significantly decreased endometrial ITGAV mRNA expression was noted in biopsies obtained from endometrioma and nonendometriotic cyst groups before surgery. Trends toward decreased endometrial HOXA-10, HOXA-11, LIF, and ITGB3 mRNA expressions were noted in the endometrioma and nonendometriotic cyst groups before surgery compared with the fertile subjects. However, the differences failed to show statistical significance. Compared with preoperative values, significantly increased HOXA-10 (12.1-fold change) and HOXA-11 (17.2-fold change) mRNA expressions were noted in endometrial biopsies obtained from subjects who were undergoing endometrioma surgery. Fold change in endometrial ITGAV mRNA after endometrioma surgery was found to be 30.1 and indicated a positive regulation. However, this fold increase was statistically insignificant. Expressions of these endometrial receptivity markers did not change significantly after surgical removal of nonendometriotic benign ovarian cysts. Conclusion(s): Laparoscopic endometrioma resection increases peri-implantation endometrial HOXA-10 and HOXA-11 mRNA expression, suggesting an improvement in endometrial receptivity.

    Ovarian cystectomy in endometriomas: Combined approach
    (GALENOS YAYINCILIK, 2014-01-01) Unlu, Cihat; Yildirim, Gazi
    Endometrioma is one of the most frequent adnexal masses in the premenopausal population, but the recommended treatment is still a subject of debate. Medical therapy is inefficient and can not be recommended in the management of ovarian endometriomas. The general consensus is that ovarian endometriomas larger than 4 cm should be removed, both to reduce pain and to improve spontaneous conception rates. The removal of ovarian endometriomas can be difficult, as the capsule is often densely adherent. While the surgical treatment of choice is surgical laparoscopy, for conservative treatment, the preferred method is modified combined cystectomy. Cystectomy can be destructive for the ovary, whereas ablation may be incomplete, with a greater risk of recurrence. To the best of our knowledge, the modified combined technique seems to be more efficient in the treatment of endometriomas.
