Effects of ranibizumab and zoledronic acid on endometriosis in a rat model.

Arch Gynecol Obstet 2021 Jun 3. Epub 2021 Jun 3.

Gynecology and Obstetrics, Balikesir University, Balikesir, Turkey.

Purpose: To investigate the histological efficacy of ranibizumab and zoledronic acid in an experimentally induced endometriosis model as compared with danazol, buserelin acetate and dienogest.

Methods: Endometrial implants were introduced in 52 female Wistar albino rats, which were then randomly divided into six groups. The animals were, respectively, given dienogest, danazol, buserelin acetate, zoledronic acid, ranibizumab and 0.9% NaCl. After 4 weeks, the volumes and histopathological properties of the implants were evaluated and the implants were excised completely at the third laparotomy. A histopathological scoring system was used to evaluate the preservation of epithelia. Endometrial explants were evaluated immunohistochemically.

Results: Among the groups, the histological score was significantly lower in the zoledronic acid and ranibizumab groups compared with the controls (p < 0.001). There were no significant differences regarding ellipsoidal volume levels between groups (p > 0.05). However, there was a statistically significant difference regarding cell numbers according to the degree of Bcl-2, NF-κB, and CD31 staining (p < 0.001). There was no statistically significant difference in Bcl-2, CD31, or NF-κB staining in the binary comparisons between the other groups (p > 0.05). For Bcl-2 staining, the staining rate of the group treated with zoledronic acid was significantly lower compared with the dienogest and danazol groups (p < 0.05). The staining rates of CD31 and NF-κB were significantly lower in the zoledronic acid and ranibizumab groups compared with the controls (p < 0.05).

Conclusion: According to these results, zoledronic acid and ranibizumab may be putative candidates for the treatment of endometriosis.

The effect of the birth method on changes of the prepartum and postpartum dimensions of perineal body.

Eur J Obstet Gynecol Reprod Biol 2021 May 5;262:36-39. Epub 2021 May 5.

Ministry of Health Ankara City Hospital, Department of Obstetrics and Gynecology, Turkey.

Objective: The perineal body is critical for maintaining the integrity of the pelvic floor, especially in females as it can be injured during vaginal delivery. This study aimed to evaluate the effect of childbirth on perineal body dimensions by using a transperineal 2D ultrasound.

Study Design: This prospective cohort study was performed in a tertiary obstetric care center. A total of 172 term pregnant women who delivered either by cesarean section or vaginal delivery were enrolled in the study. All demographic data and information were collected prospectively. The perineal body was measured in length, height, perimeter, and area. Mode of delivery was classified into four categories, including prelabor cesarean section, cesarean section during the first stage of labor, the first vaginal delivery, and more than one previously vaginal delivery. A postpartum evaluation was performed after 6 weeks.

Results: Among the 172 women, 40 (23.3 %) had a history of cesarean section (CS) and they delivered with scheduled CS, 40 (23.3 %) women delivered by primary CS during active labor, 48 (27.9 %) women had the first vaginal delivery, 44 (25.6 %) women who delivered vaginally had a history of at least one vaginal delivery. The postpartum perineal body measurements were significantly lower in terms of length, perimeter, and area in all pregnancy groups.

Conclusion: Pregnancy and delivery change perineal body dimensions, significantly. Cesarean section does not completely protect against changes in perineal body morphology.

Ovarian reserve in patients with ankylosing spondylitis.

Arch Gynecol Obstet 2021 01 8;303(1):189-193. Epub 2020 Oct 8.

Department of Obstetrics and Gynecology Ankara, Çubuk Halil Şıvgın Hospital, Çubuk, Turkey.

Purpose: The aim of this study was to determine the autoimmune effects of ankylosing spondylitis (AS) on the fertility potential of women by evaluating ovarian reserves of AS patients.

Methods: A total of 104 patients, 52 in the AS group (study group) and 52 in the control group were included in the study. Ovarian reserve was evaluated by serum anti-Müllerian hormone (AMH) levels, antral follicle count (AFC) and baseline serum follicle-stimulating hormone (FSH) levels.

Results: The mean serum AMH levels were significantly lower in the study group when compared to the controls (2.203 ± 1.110 vs. 1.188 ± 0.891, p < 0.001). In addition, the mean AFC was also significantly lower in the study group. (10.67 ± 1.81 vs. 9.54 ± 2.50, p = 0.009). Mean FSH levels were calculated to be 6.72 ± 1.14 in the study group and 7.21 ± 1.22 in the control group. The difference was not statistically significant (p = 0.781).

Conclusion: This study shows that AS like several other autoimmune conditions has an adverse effect on the female fertility potential. Therefore, an early start and long-term management of AS patients who have fertility desire is recommended. Serum AMH levels can be used in monitoring ovarian reserve and in early detection of reproductive decline of AS patients.

Clinicaltrial Number: NCT04209881.

Human Menopausal Gonadotropin Commenced on Early Follicular Period Increases Live Birth Rates in POSEIDON Group 3 and 4 Poor Responders.

Reprod Sci 2021 02 24;28(2):488-494. Epub 2020 Aug 24.

Human menopausal gonadotropin (hMG) has LH activity, and it may have beneficial effects in terms of oocyte quality and endometrial receptivity similar to recombinant LH supplementation. The aim of this study was to assess the effects of hMG, and its commencement time on the outcome of assisted reproductive technology (ART) cycles of POSEIDON group 3 and 4 poor responders. Data of 558 POSEIDON group 3 and 4 poor responders who underwent ART treatment following a GnRH antagonist cycle at a university-based infertility clinic between January 2014 and December 2019 were reviewed. hMG was commenced at the early follicular phase or mid-follicular phase in the study groups. The control group did not receive hMG stimulation. Live birth rate (LBR) was the main outcome measure. The mean duration of stimulation was significantly shorter in early follicular hMG group than in mid-follicular hMG group (11.9 ± 3.6 days vs. 12.8 ± 4 days, respectively; P = 0.027). The mean numbers of oocytes retrieved and MII oocytes were comparable between the groups. The LBRs per embryo transfer in early follicular hMG, mid-follicular hMG, and control groups were 21.9%, 11.7%, and 11.6%, respectively (P = 0.035). In conclusion, there is a significant association between the commencement time of hMG and live birth chance in ART cycles of POSEIDON group 3 and 4 poor responders. Early initiation of hMG together with rFSH seems to be beneficial in this specific population.
