STUDY OF THE ENDOMETRIAL GLANDULAR COMPONENT IN WOMEN WITH FERTILITY AND POST-COVID SYNDROME IN ANAMNESIS

The aim. To increase the effectiveness of the endometrial endometrial glandular component study in women with infertility and post-COVID syndrome. Materials and methods. A study was conducted at the State institution "Carpathian Human Reproduction Centre" of the Ministry of Health of Ukraine in the period from 2022 to the end of the first half-year of 2024. There were included 80 women in the experimental group and 40 women in the control group. The selection criterion for the study group was the presence of documented post-COVID syndrome (COVID-19 symptoms lasted longer than 12 weeks). The selection criterion for the control group was the absence of confirmed SARS-CoV-2 virus in the anamnesis. The following characteristics were common for both groups: diagnosed infertility, age – 25-42 years, written informed consent of the patient to participate in the study. The criteria for exclusion from the study for patients of both groups were: detection of human immunodeficiency virus, viral hepatitis, other sexually transmitted infections, tuberculosis of the genitourinary system, malignant diseases, mental disorders that make communication with person impossible or the awareness of written consent is questioned. General clinical and laboratory examinations and transvaginal sonographic examination of the pelvic organs were performed in the middle stage of proliferation and the middle stage of secretion according to the calendar calculation the menstrual cycle. A visually guided diagnostic office hysteroscopy was performed with the collection of biological material from the most changed areas (biopsies were collected in the middle stage of proliferation and the middle stage of secretion in different menstrual cycles). A routine staining of samples with hematoxylin-eosin, morphometry of the endometrial glandular component, optical determination of the number of glands and measurement of the diameter of the lumen of the studied glands, considering the possible measurement error, glandular-stromal ratio, functional activity of the glands, were performed. A histochemical PAS-reaction to identify the glycoproteins of gland secretions and immunohistochemical staining of the glandular epithelium to express the receptivity of the glands to estrogen and progesterone were carried out. The results. After conducting the PAS-reaction, a higher secretion was noted in the glands than in the stroma of the endometrium during the period of the implantation window in both cohorts. No statistically significant difference between the groups in the amount of glycogen of the middle proliferative phase in the glands (p=0.315) or stroma (p=0.486). Glycogen in this phase was visualized of very small granules and coarse granules, without their formation in clusters. A decrease in secretion was established in 16 (40%) patients of the control group and 49 (61.3%) women of the experimental group in the middle secretory phase, which was statistically significant (p=0.028). A decrease in the expression level of the progesterone receptor in the middle secretory phase was found to be significantly more pronounced in the experimental group than in the control group (р=0.044). Conclusions. In the middle secretory phase, a decrease in the secretion of glycogen by the endometrial glands and a decrease in the level of expression of the progesterone receptor in endometrial biopsies were detected by the routine histological, histochemical techniques and immunohistochemical stude in women with infertility and a history of post-COVID syndrome.

The HYsteroscopic Miscarriage MaNagement (HYMMN) pilot randomized-controlled trial

ObjectiveTo evaluate the feasibility of performing a full-scale, adequately powered, multi-center randomized controlled trial (RCT) assessing the effectiveness of office hysteroscopy (OH) for the treatment of retained pregnancy tissue (RPT) after miscarriage, compared with standard treatment (ST) (expectant/medical/surgical), on future pregnancy outcome. Study designSingle-center pilot RCT performed at Birmingham Women’s Hospital, UK. Patients opting for non-surgical miscarriage management at ≤14 weeks gestation who wanted to conceive as soon as possible were recruited and offered a transvaginal ultrasound scan (TVUS) eight weeks later to check for the presence of RPT. Patients with RPT were randomized in a 1:1 ratio using a computer-generated online random allocation sequence to either OH (performed using the TruClear 5.0 hysteroscopic tissue retrieval system) or ST (the type of which was recommended based on symptoms, urinary pregnancy test and scan findings). Results158 participants were approached for inclusion into the trial, of which 149 (94.3%) agreed. Of the 126 that underwent TVUS, RPT were diagnosed in 42 patients (33.3%). 21 patients were randomized to OH, of whom 18 underwent the procedure because three fell pregnant after their TVUS. OH was deemed acceptable to all patients without any serious complications. 21 patients were randomized to ST where 16 patients (76%) were recommended expectant management and five (24%) were recommended surgical management. 115 patients (91%) were able to provide pregnancy data, however, the study was not powered to show a clinically significant difference. ConclusionA full-scale, adequately powered, randomized clinical trial investigating OH against ST for the treatment of RPT following miscarriage is clinically relevant and feasible owing to high rates of participation, acceptability and satisfaction and low rates of attrition associated with the proposed interventions.

Evaluation of Vaginoscopic versus Traditional Office Hysteroscopy in Nulliparous Infertile Patients (prospective Cohort study)

Evaluation of Vaginoscopic versus Traditional Office Hysteroscopy in Nulliparous Infertile Patients (prospective Cohort study)

A Deeper Look at Office Hysteroscopy in Asymptomatic Postmenopausal Patients: indications and outcomes of 822 Cases.

Study ObjectiveThis study aims to assess the prevalence of malignancy and other endometrial pathologies in asymptomatic postmenopausal women referred for office hysteroscopy, identify main referral indications, and assess their relationship with the risk of malignancy.Secondary objectives included evaluating the association between ultrasound variables and malignancy risk and assessing procedure validity, which encompasses duration, feasibility and patient comfort during office hysteroscopy. DesignRetrospective analysis. SettingThe study was conducted at the Department of Gynecology, Division of Gynaecology and Obstetrics, University Medical Centre Ljubljana, Slovenia's largest tertiary care center. ParticipantsThe cohort consisted of 822 asymptomatic postmenopausal women referred for office hysteroscopy, excluding those with postmenopausal bleeding within the last year. InterventionsParticipants underwent office hysteroscopy with or without biopsy. Measurements and Main ResultsThe main indication for hysteroscopy was ultrasound abnormalities alone, with remaining indications including a combination of ultrasound and clinical findings. Among the cohort, 97.4% exhibited benign findings, while 2.6% were diagnosed with cancer or precancerous lesions. The analysis revealed that patients with indications based on ultrasound and clinical findings suggestive of malignancy had a higher risk of malignancy compared to those with ultrasound alone. In 387 patients with documented ultrasound variables, inhomogeneous endometrial appearance (OR: 8.2, 95% CI: 2.4-27.9, p<0.001) and significant liquid content within the uterine cavity (OR: 10.2, 95% CI: 3.6-28.9, p<0.001) exhibited strong associations with malignancy. Analysis of the procedure revealed a high feasibility rate (87.8%), with a median duration of 13,7 minutes and a median VAS pain score after the procedure of 3/10. ConclusionsThe prevalence of endometrial cancer and precancerous lesions in asymptomatic postmenopausal patients is likely low, with most intrauterine pathologies being benign. Our study demises the utility of routine endometrial surveillance for this population in the absence of specific risk factors. A holistic approach, considering individualized assessments and factors beyond endometrial thickness, is crucial in interpreting ultrasonic findings.

Experience of Using Biomodeling in Training Obstetricians and Gynecologists in the Technique of Office Hysteroscopy

The leading place in the structure of gynecological diseases is occupied by intrauterine pathology, the "gold standard" of treatment of which is therapeutic hysteroscopy. Conducting hysteroscopy in outpatient conditions in the absence of anesthesia significantly reduces the workload of the inpatient unit, but requires high-quality training of specialists due to the labor intensity of the manipulation and the lack of opportunity to acquire skills intraoperatively. The use of biomodels for training allows specialists to master this technique in a short time.

The efficacy of early office hysteroscopy in preventing intrauterine adhesions after abortion: a randomized controlled trial

BackgroundIntrauterine adhesions (IUA) are a challenging clinical problem in reproductive infertility. The most common causes are intrauterine surgery and abortions. We aimed to investigate whether early second-look office hysteroscopy can prevent IUA.MethodsA single-center, prospective, two-armed, randomized controlled trial was designed to explore the efficacy of early office hysteroscopy after first-trimester induced abortion (suction dilatation and curettage [D&C]) and to further analyze fertility outcomes. Women aged 20–45 years undergoing suction D&C and desiring to conceive were recruited. Between October 2019 and September 2022, 66 women were enrolled, of whom 33 were allocated to group A (early hysteroscopy intervention). The women in intervention group A were planned to receive 2 times of hysteroscopies (early and late). In group B, women only underwent late (6 months post suction D&C) hysteroscopy.ResultsThe primary outcome was the IUA rate assessed using office hysteroscopy 6 months after artificial abortion. Secondary outcomes included menstrual amount/durations and fertility outcomes. In intervention group A, 31 women underwent the first hysteroscopy examination, and 15 completed the second. In group B (late hysteroscopy intervention, 33 patients), 16 completed the hysteroscopic exam 6 months after an artificial abortion. Twenty-one women did not receive late hysteroscopy due to pregnancy. The IUA rate was 16.1% (5/31) at the first hysteroscopy in group A, and no IUA was detected during late hysteroscopy. Neither group showed statistically significant differences in the follow-up pregnancy and live birth rates.ConclusionsEarly hysteroscopy following suction D&C can detect intrauterine lesions. IUA detected early by hysteroscopy can disappear on late examination and become insignificant for future pregnancies. Notably, the pregnancy outcomes showed a favorable trend in the early hysteroscopy group, but there were no statistically significant differences.Trial registrationClinicalTrials.gov, ID: NCT04166500.

Hysteroscopic Endometrial Fundal Incision versus Hysteroscopy Only in Oocyte Recipients: A Randomized Controlled Trial Assessing The Reproductive Outcomes.

Endometrial scratching (ES) remains controversial regarding its potential effectiveness in improving pregnancy rates. The objective of the present study was to assess the impact of endometrial fundal incision (EFI) during hysteroscopy on reproductive outcomes in a population of oocyte recipients. A randomized controlled trial was conducted between 2020 and 2023 at the Third Department of Obstetrics and Gynecology, School of Medicine, Faculty of Health Sciences, Aristotle University of Thessaloniki and "Assisting Nature Centre of Reproduction and Genetics". The study population consisted of women who underwent hysteroscopy randomly assigned in a 1:1 ratio to either EFI (one to three months before embryotransfer with donor oocytes) or no intervention throughout office hysteroscopy. Clinical pregnancy and live birth rates were the primary outcomes. After the exclusion of patients with intraoperative diagnosed endometrial pathology, a total of 124 women underwent randomization. The pregnancy test was positive in 79% (n=49/62) of the women in the EFI compared to 59.7% (n=37/62) in the hysteroscopy-only group (P=0.019), while the live birth rates did not differ between the two groups (58.1%, n=36/62 vs. 51.6%, n=32/62, P=0.470). EFI during hysteroscopy seems to improve pregnancy rates in oocyte recipients without intrauterine pathology, while live birth rates are not affected by the EFI. These results should be interpreted with caution before the implementation of EFI in the routine in vitro fertilization (IVF) practice (registration number: NCT04580056).

P-302 Oral ofloxacin combined with vaginal metronidazole for chronic endometritis: a prospective open-label cohort study

Abstract Study question Does oral ofloxacin 2x200 mg for 10 days combined with vaginal metronidazole 1x500 mg for 10 days reduce the activity of chronic endometritis? Summary answer The investigated antibiotics may be beneficial in some cases of chronic endometritis, except in cases of concomitant endometrial polyp, where they adversely affect treatment outcome. What is known already Chronic endometritis (CE) is characterized by the presence of atypical plasma cell infiltrates (CD138 positive) in the endometrial stroma. CE may adversely affects fertility by reducing endometrial receptivity, impairing decidualization and uterine contractility, thus increasing the risk of recurrent pregnancy loss and implantation failure. Some idiopathic infertility cases are attributed to CE. The diagnostics of CE is challenging because the clinical evaluation is nonspecific and the immunohistochemical criteria are not consistent between research centers. Literature data suggested that successful treatment of CE with antibiotics could improve live birth rates, but a preferred treatment regimen has not been identified. Study design, size, duration A prospective cohort study included women undergoing office hysteroscopy (OH) at a tertiary referral center in 2021-2023. Women diagnosed with CE were assigned, based on their preference, to the intervention arm of ofloxacin 2x200 mg orally for 10 days + metronidazole 500 mg vaginally for 10 days or to the control arm (no antibiotics). 100 women underwent repeated hysteroscopy after 3 cycles, of which 77 received antibiotics and 23 were controls. Participants/materials, setting, methods Women aged 18-45 who met eligibility criteria for OH were included. Karl Storz 5.0 mm Bettocchi® operating sheath with a 2.9 mm 30° telescope and a 5Fr working channel was used. Endometrial lesions or biopsy specimens were collected with grasping forceps, blunt scissors or bipolar needle electrode. Saline was used as the dilating medium. Tissue samples were subjected to histopathological examination. Plasma cells were detected by immunohistochemical staining with Monoclonal Mouse Anti-Human CD138 antibodies. Main results and the role of chance The most common findings identified at hysteroscopy were endometrial polyps (43%), polypoid endometrium (38%), micropolyps (23%), focal (27%) and diffuse hyperemia (18%) and cesarean scar defect (14%). CE was defined as the presence of &amp;gt; 2 plasma cells/mm2. The Mann-Whitney U test showed a significantly higher plasma cell count (PCC) in the presence of a cesarean scar defect than in other cases (23 vs. 18/mm2, p = 0.031) and a tendency towards a lower PCC in micropolyps (9 vs. 21/mm2, p = 0.063). The correlation of hysteroscopic findings with CE activity was weaker than expected. Using repeated measures ANOVA, no difference in PCC between primary and follow-up hysteroscopy was found in either arm (p = 0.8), while post-hoc tests showed that the mean PCC decreased from 12 to 5/mm2 (p = 0.02) in the intervention arm, and from 14 to 6 (p = 0.23) in the control arm. On follow-up hysteroscopy, polyp remission was observed significantly more often in the control arm than in the intervention arm (61% vs. 27%, pChi2=0.02), in which de novo polyp was observed in 4%. In polypoid endometrium, the remission rate was similar in both arms (19% vs. 22%), and the rate of de novo lesions was significantly lower in interventional arm (16% vs. 39%, pChi2=0.035). Limitations, reasons for caution The limitations include the small sample size, the CE definition based on the number of plasma cells calculated using the Receiver Operating Characteristic curve for the purposes of the study, and the empirical selection of antibiotic therapy. Wider implications of the findings Due to the weak correlation of hysteroscopic findings with CE activity, the diagnostics and treatment of CE based on clinical evaluation of the uterine cavity is not justified. Poorly selected antibiotic therapy may adversely affect the outcomes of treatment. Trial registration number 1072.6120.322.2020

Hysteroscopic evaluation of endometrial changes and fallopian tubal functions in women using progestin-only contraceptives

The purpose of this prospective study was to investigate whether office hysteroscopy (OH) can be used to assess the mechanisms of action of progestogen-only contraceptives (POCs), diagnose possible local causes of abnormal uterine bleeding (AUB), and support the treatment plan of symptomatic patients using POCs compared with those who do not use hormones. The study included 140 women who were divided into two groups. Group A consisted of 70 women who used POCs, whereas group B consisted of 70 women who did not use hormones. They were successively examined using transvaginal ultrasonography (TVS), OH, and endometrial sampling. The TVS results were consistent with those of OH and histopathology. The changes in endometrial thickness and vasculature, as well as fallopian tube (FT) functions, were significantly more pronounced in POC users than in non-POC users. There was a significant reduction in the peristalsis of the proximal part of the FT, as well as a reduction in the bubble flow test in group A compared with group B. In addition, the combination of peristalsis and the bubble flow test (Darwishscope test) was significantly lower in group A. It was concluded that using OH as a simple diagnostic tool in women with POCs would contribute to a better understanding of the mechanisms of endometrial and FT effects and explain some local endometrial causes of AUB. This ensures that the combination of TVS and OH would limit routine endometrial sampling in POCs users.

Stage II endometrial cancer: The diagnostic power of hysteroscopic excisional biopsy and MRI in the pre-operative cervical stroma assessment

Introduction/backgroundStage II Endometrial cancer (EC) accounts only for 12% of cases. Recent evidences redraw the weight of radicality in this stage as it would seem to have no impact on survival outcomes claiming for radicality when free surgical margins are not ensured to be achieved by simple hysterectomy. Thus, an accurate pre-operative evaluation might be crucial. This study aims to estimate the diagnostic power of Hysteroscopic excisional biopsy (HEB) of cervical stroma alone and combined with Magnetic resonance imaging (MRI) to predict the stage and concealed parametrial invasion in patients with preoperative stage II EC. MethodologyFrom January 2019 to November 2023, all patients evaluated at the Department of Gynaecology Oncology of Humanitas, Istituto Clinico Catanese, Catania, Italy, with a diagnosis of EC and evidence of cervical stromal diffusion on preoperative MRI and/or office hysteroscopy evaluation, considered suitable for laparoscopic modified type B hysterectomy, were consecutively included in the study. These underwent endometrial and cervical hysteroscopy excisional biopsy (HEB) for histological evaluation before definitive surgery. The data obtained were compared with the definitive histological examination (reference standard). ResultsSixteen patients met the including/excluding criteria and were considered into the study. Stage II endometrial cancer were confirmed in 3 cases (18.7%). We reported 2 (12,5%) parametrial involvement (IIIB), 4 (25%) cases of lymph nodes metastasis (IIIc), 7 (43,7%) cases of I stage. MRI had a sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy (95% CIs) of 71%, 44%, 50%, 66% and 56.2 % respectively.HEB showed sensitivity, specificity, PPV, NPV and accuracy (95 % CI) of 85 %, 89 %, 85 %, 88 % and 87 % respectively. Comparing HEB + MRI to HEB alone, no statistical differences were noted in all fields. Considering parametrial invasion, MRI had better sensitivity but there were no statistical differences to HEB in other fields, showing both a worthy NPV. ConclusionHEB was accurate in all fields for cervical stroma assessment and had a fine NPV to exclude massive cervical involvement up to parametrial. Considering the new FIGO staging a preoperative molecular and histological evaluation of the cervical stroma may be useful. Operative hysteroscopy seems to be a feasible and accurate method for this purpose.

Feasibility of Office-Based Operative Hysteroscopy by a Tissue Removal System Without Anesthesia

To investigate the feasibility of operative hysteroscopy by a hysteroscopic tissue removal system (HTRS) without anesthesia in women with endometrial polyps (EP) or retained products of conception (RPOC). Prospective observational cohort study. University-affiliated Department of Obstetrics and Gynecology. Consenting women aged >18 years diagnosed with EP or RPOC from 9/2022 to 8/2023 confirmed by a prior office hysteroscopy. Office-based vaginoscopic operative hysteroscopy without anesthesia using the Mini-Elite Truclear HTRS. Oral misoprostol was prescribed for cervical ripening. The patients rated intraoperative and 5-minute postoperative pain levels on a visual analog scale, with mild pain defined as a score of 0 to 4, moderate as 5 to 7, and severe as 8 to 10. A successful procedure was defined as complete removal of the pathology. Fifty patients were included in this pilot study, and 47 (94.0%) procedures were completed successfully, including 21/24 (87.5%) cases of EP and all cases of RPOC (26/26, p = .06). No intra- or postoperative complications occurred. The intraoperative pain levels were rated as mild, moderate, and severe by 26 (52.0%), 16 (32.0%) and 8 (16.0%) patients, respectively. Severe intraoperative pain was more common in nulliparous women and those >10 years from their last vaginal delivery and was not associated with patient age, menopausal status, presence of abnormal uterine bleeding, or pathology size. Severe postoperative pain, reported by 5 (10.0%) patients, was significantly associated with removal of EP compared with RPOC, longer operative time, and nulliparity or >10 years from the last vaginal delivery. The procedure was considered acceptable by 46 (92.0%) patients, and 45 (90.0%) would recommend it to a friend/relative. Office-based operative hysteroscopy by the HTRS is successful and well tolerated by most women, especially for RPOC removal.

Correlation between hysteroscopic features and specific microbial species in women with chronic endometritis

Objective and rationaleChronic endometritis (CE) has recently been associated with unexplained infertility and recurrent miscarriages. The current gold standard for CE detection is histopathological examination. However, office hysteroscopy and endometrial cultures are also significant, due to the possible link between CE and various microorganisms. Bacterial colonization of the endometrium has been associated with reduced success rates of in vitro fertilisation embryo transfer. Few studies have tried to correlate CE hysteroscopy findings with pathogenic microorganisms. This prospective cohort study sought to establish whether hysteroscopic diagnostic lesions correlate with specific microbial species. MethodsThe study encompassed women undergoing diagnostic tests for a range of subfertility health issues. 189 women completed the standard office diagnostic hysteroscopy (DH). 181 had also endometrial samples taken for microbial culture investigation. Correlation analysis (χ2 and Fisher's exact test) between hysteroscopic findings suggestive of CE and endometrial cultures was carried out. Logistic regression models were also fitted to measure whether a positive endometrial culture could affect CE conditions. ResultsA significant association of E. coli was observed between the hysteroscopically characterized CE + group with focal hyperplasia, when compared to the non–CE group. Logistic regression analysis revealed that women positive for E. coli were 4.423 times more likely to have focal endometrial hyperplasia. No other significant correlations were identified between DH and positive endometrial cultures. ConclusionsThe presence of E. coli in the endometrium was significantly correlated with focal hyperplasia findings from hysteroscopy, emphasizing the importance of microbial cultures in the diagnosis and targeted treatment of CE in women with subfertility.

Clinical utility of office hysteroscopy following failed invitro fertilization-embryo transfer: A retrospective cohort study.

Despite its widespread use, invitro fertilization (IVF) outcomes are challenged by implantation failure, largely due to factors such as embryo quality and endometrial receptivity. In this study, we investigated the clinical effect of office hysteroscopy (OH) on the subsequent frozen-thawed embryo transfer (FET) in infertile women who experienced a failed IVF-embryo transfer (IVF-ET) cycle. We included 577 infertile women who underwent OH because of a history of failed ET between October 2019 and September 2021. During OH, visible endometrial polyps (EPs) were diagnosed and removed by curette or biopsy forceps; chronic endometritis (CE) was diagnosed by histopathology and immunohistochemistry and treated with oral doxycycline (0.2 g/d) for 14 days. According to the hysteroscopic findings and endometrial pathology with immunohistochemistry, patients were divided into three groups: group A (n = 161) had CE with or without EPs, group B (n = 156) had EPs only, and group C (n = 260) had no CE or EPs. In the following FET cycle, the implantation rates were 47%, 51%, and 45% (P = 0.411); the clinical pregnancy rates were 56%, 62%, and 55% (P = 0.436); the live birth rates were 45%, 51%, and 42% (P = 0.205); and the miscarriage rates were 18%, 16%, and 22% (P = 0.497) in groups A, B, and C, respectively. There were no significant differences among groups (P > 0.05). OH is helpful for diagnosis and treatment of abnormal intrauterine environment in women with a failed IVF cycle and further improves their pregnancy outcome in the following FET.

Outpatient hysteroscopy: Suitable for all? A retrospective cohort study of safety, success and acceptability in Australia.

In Australia, gynaecologists continue to assess and investigate abnormal uterine bleeding with inpatient hysteroscopy despite evidence validating outpatient hysteroscopy services. This retrospective cohort study assessed the safety, success and acceptability of office hysteroscopy in a gynae-oncology rapid-access clinic over six years in Sydney, Australia, and included all women without an age or body mass index (BMI) cut-off using a 'see and treat' concept. A database was created and analysed retrospectively for patients who attended office hysteroscopy service between January 2016 and March 2021 (63 months, 481 eligible). An anonymous modified PAT-32 patient satisfaction questionnaire was also offered to an initial cohort after their procedure to gauge insightful feedback about acceptability. A total of 92% of patients had successful outpatient hysteroscopic access; 24% of cases required hysteroscopy under general anaesthesia (GA) despite pathology in over 50% of cases; 68% of the total were able to be managed with outpatient hysteroscopy and did not require a follow-up GA hysteroscopy. This paper is also the first of its kind to our knowledge to incorporate patients >65 years, those with a BMI >35 and those with a history of cervical stenosis. This study suggests that age and BMI do not impact the success rate of the procedure. This study demonstrates that outpatient hysteroscopy is an acceptable, safe procedure that is well tolerated by patients. Considering our rapid-access hysteroscopy service allowed 68% of the patient cohort to avoid hysteroscopy under GA, we estimate conservatively ~$63 million per year in Australia could be saved by performing office hysteroscopies.
