Prevalence of chronic endometritis in infertile women undergoing hysteroscopy and its association with intrauterine abnormalities: A Cross-Sectional study.

OBJECTIVE: Chronic endometritis (CE) is an inflammatory condition with several different risk factors. We aimed to examine whether intrauterine abnormalities, such as endometrial polyps, submucosal myomas, intrauterine adhesions, or a septate uterus, were associated with an increased likelihood of developing chronic endometritis. METHODS: A cross-sectional study was conducted on 335 infertile women who underwent hysteroscopy surgery at the Ayatollah Taleghani Hospital Infertility Center, affiliated by Shahid Beheshti University of Medical Sciences, in 2022. All participants in the study underwent hysteroscopic surgery, which allowed for direct visualization of the intrauterine cavity, and endometrial biopsies were taken for further analysis. To characterize endometritis, plasma cell infiltration was assessed. Patients with ≥5 plasma cells observed in 10 high-power fields were defined as having chronic endometritis. RESULTS: Endometritis was observed in 51.3% of the patients, totaling 172 individuals. Logistic regression analysis revealed that patients with endometrial polyps had 5.2 times higher odds of developing endometritis compared to patients without polyps (95% CI = 2.9, 9.2) (p-value <0.001). Similarly, patients with intrauterine adhesions had a significant increase in the odds of endometritis (OR = 4.6, 95% CI = 2.1, 10.1) (p-value <0.001). CONCLUSIONS: Treatment or removal of endometrial abnormalities through hysteroscopic procedures may help to reduce the risk of chronic endometritis and improve fertility outcomes. Further research is necessary.

Comparison In Vitro Fertilization Outcomes between DouStim and Minimal Stimulation Protocols in Poor Ovarian Responders: A Randomized Clinical Trial.

BACKGROUND: Various protocols have been approved to improve the response rate leading to successful fertilization in poor ovarian responders (PORs). The application of double ovarian stimulation (DuoStim) in the follicular and luteal phases of the same ovarian cycle has been shown as an intriguing option to achieve more oocyte retrievals in the shortest time. The aim of the current study is to compare the outcomes of different protocols, minimal stimulation (MS) and Duostim. MATERIALS AND METHODS: This randomized clinical trial was performed on 42 in vitro fertilization (IVF) candidates with POR diagnosis. Patients were classified into two equal groups and treated with the DuoStim protocol and MS protocol. The IVF outcomes, including retrieved follicles, oocytes, metaphase II (MII) oocytes and embryos, were compared between these groups. RESULTS: The patients' characteristics including age, anti-mullerian hormone (AMH), follicle stimulating hormone (FSH), luteinizing hormone (LH), and antral follicle count (AFC) were collected and compared. It showed there was no significant difference between the two groups baseline characteristics (P>0.05). We observed that the DuoStim protocol resulted in a significantly higher score in comparison with the MS protocols , including the number of follicles (6.23 ± 2.93 vs. 1.77 ± 1.66, P<0.001), retrieved oocytes (3.86 ± 2.57 vs. 1.68 ± 1.58, P=0.002), MII oocytes (3.36 ± 2.42 vs. 1.27 ± 1.27, P=0.001) and obtained embryos (2.04 ± 1.64 vs. 0.77 ± 0.86, P=0.003). CONCLUSION: The DuoStim protocol is a favourable and time saving plan that is associated with more oocytes in a single stimulation cycle. The DuoStim protocol significantly can result in more frequent MII oocytes and embryos. We figured that the higher number of oocytes and embryos might have led to a higher rate of pregnancy (registration number: IRCT20200804048303N1).

Severe early ovarian hyperstimulation syndrome following GnRH agonist trigger and freeze-all strategy in GnRH antagonist protocol; case report and literature review.

Ovarian hyperstimulation syndrome (OHSS) is characterized by increased vascular permeability, hemoconcentration and fluid leakage to the third space. The vast majority of OHSS cases occur following ovarian stimulation for IVF. This potentially lethal iatrogenic condition is one of the most serious complications of assisted reproductive technologies. We report one case of severe early OHSS after GnRH agonist trigger in a GnRH antagonist protocol and freeze-all approach without the administration of any hCG for luteal-phase support in a 34-year-old case of PCO with 7 years primary infertility. After oocyte retrieval the patient was seen at the emergency unit of the hospital with abdominal distension, pain, anuria, dyspnea, and OHSS symptoms. The diagnosis was OHSS with severe ascitis. She was admitted to the Intensive care unit (ICU). She was managed with oxygen by mask, intravenous fluids, anticoagulant and albumen, we performed a two-time vaginal ascites puncture, resulting in the removal of 7800mL of clear fluid in Intensive Care Unit with full recovery. This case study presents the clinical manifestations, investigation, progress, management, outcome and preventive measures. The patient was managed with no complications. Clinicians have to be aware that even the sequential approach to ovarian stimulation with a freeze-all approach and GNRH analog triggering does not completely eliminate OHSS in all patients.

Comparison of cerclage and pessary in prevention of preterm birth in twin pregnancies.

Background: The preterm labor has increased in multiple pregnancies over the past 2 decades. Preterm labor has led to increase in neonatal mortality rates, long-term morbidity, respiratory distress, and neonatal infections. Thus, this study aimed at investigating the effect of cerclage versus pessary on the prevention of preterm birth in twin pregnancies. Methods: This prospective randomized clinical trial was performed on 50 women pregnant with twins who visited Taleghani hospital in 2016-2018. Their cervical length, which was measured by transvaginal ultrasonography (TVS), was less than 30 millimeters at week 14 of pregnancy. The participants were randomly divided into 2 groups (n=25). They separately underwent cervical pessary and cerclage. McDonald's procedure was performed in cerclage group from 14 to 27 weeks. The suture material was Mersilene Ethicon 5-0 double-armed s14 needle. Ring hodge pessary was also inserted in the vagina of the participants in the pessary group. All the patients were injected 250 mg intramuscular 17 alpha-hydroxyprogesterone caproate weekly from week 16 to week 36. All statistical analyses were performed using SPSS 18 software. Results: The results of this study showed that the mean ± standard deviation (SD) for pregnancy length of the cerclage and pessary groups were 238.6±32.4 and 223.6±16.6, respectively. Also, significant differences were found between the 2 groups (p=0.048). No significant difference was found in pregnancy (p=0.565), length of pessary/cerclage use (p=0.491), and BMI before and after delivery between the cerclage and pessary groups (p>0.05). Conclusion: The use of cerclage in twin pregnancies is recommended to increase the length of pregnancy.

Effect of myo-inositol supplementation on ICSI outcomes among poor ovarian responder patients: A randomized controlled trial.

PURPOSE: This study has evaluated the use of myo-inositol supplementation for improving reproductive outcomes in poor responders undergoing intracytoplasmic sperm injection (ICSI). METHODS: One hundred and twelve poor responder patients were included in the study and randomly categorized into two groups using a permuted block randomization method. Group A included 56 patients who received myo-inositol (4 g) and folic acid (400 µg) daily from one month before starting the ICSI cycle continuing until the ovulation triggering day. Group B included 56 patients consuming only folic acid (400 µg) daily for the same period. The outcome measures were the number of retrieved oocytes, embryo quality, Ovarian Sensitivity Index (OSI: number of oocytes retrieved/total Gonadotropins units × 1000), fertilization, implantation, and ongoing pregnancy rates. RESULTS: No significant difference was observed between the two groups regarding the total dose of gonadotropin used, OSI, and the number of total retrieved and mature oocytes. Grad A embryos and fertilization rate were significantly increased in group A. Implantation and pregnancy rates showed statistically insignificant changes. CONCLUSION: Treatment of poor responders with myo-inositol from one month before starting ICSI cycle continuing until ovulation trigger can improve fertilization rate and embryo quality, and may enhance the cumulative pregnancy rate in poor responders.
