    Receptivity-based uterine fibroid surgery: an updated systematic review of the evidence
    (IMR PRESS, 2022-01-01) Celik, Onder; Koc, Onder; Yurci, Arzu; Ersahin, Aynur; Celik, Nilufer; Tanilir, Fatma; Gurkan, Naziye; Ozyurt, Ramazan; Ozcil, Mustafa Dogan; Duran, Bulent; Unlu, Cihat
    Background: Analyzing expression patterns of receptivity genes is a minimally invasive diagnostic method to identify the underlying cause of subfertility in women with uterine fibroid with a history of implantation failure or recurrent pregnancy loss. This updated systematic review was designed to determine the molecular and genetic changes in the endometrium of women with fibroid and how myomctomy affect the outcome of spontaneous or assisted conception treatment. We also discussed the extent to which we should consider the effects of fibroids on endometrial receptivity when deciding whether or not to perform myomectomy. Methods: A total of 184 articles reached as a result of PubMed research and meeting the selection criteria, were evaluated. Of these, 28 full text articles on uterine leiomyoma and endometrium, leiomyoma and receptivity, fibroid and implantation, myomectomy and implantation, fibroid and genes, fibroid surgery and receptivity, fibroid and uterine peristalsis, fibroid and immune cell were evaluated. Results: The endometrium of subfertile women with fibroid appears to have a disease specific pattern according to the type of the fibroid. The response of the endometrium to a fibroid may vary depending on whether the fibroid is close or far from it. Leiomyomas that contribute to subfertility must be near to or in contact with the endometrium, as is the case for Types 0, 1 and 2 leiomyomas. The proximity to the endometrial cavity makes the effect of fibroid on the endometrium more pronounced. While Type 3 fibroid causes subfertility similar to submucosal fibroids, the subfertility-producing effects of Type 4 fibroids have not been clearly clarified. However, the fact that the fibroid is far from the cavity should not mean that it has no effect on the endometrium. The mechanical stress created by a Type 4 fibroid that is not connected to the endometrium may be converted into biological signal and disrupt receptivity. Data on whether myomectomy restores impaired receptivity are mostly based on clinical observations, and studies evaluating endometrial receptivity before and after myomectomy are very few. Conclusions: Analysis of receptivity genes in subfertile women with fibroid may assist the clinician in deciding whether or not to perform myomectomy. If it is determined whether fibroids affect receptivity other than their mechanical effects, the indications for myomectomy may expand or narrow.

    Comparison of endometrial prostanoid profiles in three infertile subgroups: the missing part of receptivity?
    (ELSEVIER SCIENCE INC, 2020-01-01) Keles, Irem Demiral; Ulgen, Ege; Erkan, Melike Belkiz; Celik, Saliha Esin; Aydin, Yasemin; Onem, Ayse Nur; Kandemir, Hulya; Arslanoglu, Tugce; Apak, Mustafa Resat; Sezerman, Ugur; Yeh, John; Buyru, Faruk; Bastu, Ercan
    Objective: To study the prostanoid profile of the endometria of patients with recurrent implantation failure (RIF), unexplained infertility (UIF), and recurrent miscarriages (RM), and to compare them with the endometria of healthy fertile controls. Design: Prospective cohort study. Setting: University hospital. Patient(s): Fifteen patients with RIF, 18 patients with UIF, 16 patients with RM, and 23 fertile controls were recruited. Intervention(s): Endometrial samples were taken during the window of implantation. After tissue homogenization and extraction, analysis with ultra-performance liquid chromatography diode array detector electrospray ionisation tandemmass spectrometrywas performed. Main Outcome Measures: Concentrations of prostaglandin (PG) D1, PGE1, PGF1 alpha, 6-ketoPGF1 alpha GD2, PGE2, PGF2 alpha, 15-deoxy-Delta 12,14-PGJ2, PGD3, PGE3, PGF3 alpha, thromboxane B2, 13,14-dihydro-PGE1, 13,14-dihydro-PGF1 alpha, 13,14-dihydro-PGF2 alpha, 13,14dihydro-15-keto-PGE1, 13,14-dihydro-15-keto-PGE2, and 13,14-dihydro-15-keto-PGF2 alpha were assessed. Result(s): Comparison of the endometria of patients with UIF and the controls showed no statistically significant differences. When the endometria of patients with RIF were compared with the controls, thromboxane B2 (TXB2) was found significantly higher (843.1 pg/mg vs. 133.5 pg/mg). When the endometria of patients with RM were compared with controls, 13,14-dihydro-15-keto PGF2 alpha and TXB2 were found significantly higher (3907.30 pg/mg vs. 17.80 pg/mg and 858.7 pg/mg vs. 133.5 pg/mg respectively). Conclusion(s): We identified increased endometrial presence of TXB2 in patients with RM and RIF, and 13,14-dihydro-15-keto PGF2 alpha in patients with RM. Although common ground is observed for RM and RIF, prostanoids, on the other hand, might make their own contribution to endometrial receptivity as important as genes and proteins. Attempts to normalize the prostaglandin profile of the endometrium via enzymatic activity can open new therapeutic options. (C) 2019 by American Society for Reproductive Medicine.
