Questionable recommendation for LPS for IVF/ICSI in ESHRE guideline 2019: ovarian stimulation for IVF/ICSI

Perinatal complications and neonatal outcomes in in vitro fertilization/intracytoplasmic sperm injection: a propensity score matching cohort study

Background

The utilization of in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) has witnessed a significant increase in recent years. However, the comparative perinatal and neonatal outcomes compared to natural pregnancies are unclear. This study aims to compare the outcomes of pregnancies from IVF and ICSI with natural pregnancies.

Methods

This retrospective, propensity score-matched cohort study was conducted at the First People's Hospital of Shangqiu and The First Affiliated Hospital of Xinjiang Medical University, involving 5,628 patients from February 2019 to December 2022. It compared pregnancies achieved through IVF/ICSI with those conceived naturally. The primary outcomes assessed were perinatal complications and neonatal health parameters. Propensity score matching and multivariate logistic regression analysis were employed to adjust for potential confounders and identify independent associations.

Results

After propensity score matching, the IVF/ICSI group demonstrated significantly higher rates of placental adherence (12.1% vs. 7.4%, p < 0.001) and postpartum hemorrhage (11.1% vs. 7.6%, p = 0.002) compared to the NP group. Neonates in the IVF/ICSI group had a lower gestational age (38.21 ± 2.12 weeks vs. 38.63 ± 2.29 weeks, p < 0.001), reduced birth weight (3159.42 ± 722.75 g vs. 3211.31 ± 624.42 g, p = 0.032), and an increased preterm delivery rate (11.2% vs. 8.9%, p = 0.017). Multivariate analysis further confirmed these findings, highlighting the independent associations between IVF/ICSI and these adverse outcomes.

Conclusion

This study suggests a potential correlation between the use of IVF/ICSI and unfavorable perinatal and neonatal outcomes. These findings underscore the critical need for ongoing monitoring and research efforts to enhance the safety and effectiveness of these reproductive technologies.

EFFECTIVENESS OF HORMONAL MONOTHERAPY BEFORE SURGICAL TREATMENT IN PATIENTS WITH EXTERNAL GENITAL ENDOMETRIOSIS

OBJECTIVE

The aim: Evaluation of the effectiveness of hormone therapy before and after surgical treatment in patients with external genital endometriosis (HRT).

PATIENTS AND METHODS

Materials and methods: Bibliographic, information-analytical, clinical-instrumental, laboratory, histomorphological methods were used in the work. The sources of information were data from the scientific literature on the topic of the study, modern guidelines, a review of randomized controlled studies.

RESULTS

Results: All women involved in the study received hormone therapy before and after surgery for 3-6-9 months: 45.0% - only COCs, 25.0% - courses of a-GnRH drugs; 30.0% - only progestogens. Comparative evaluation of the function of the relapse-free course of UHD using the Kaplan-Meier method showed that when using a-GnRH in patients with UHD, the duration of the relapse-free period is higher than for other groups of drugs: the indicator of the function of maintaining remission before surgical treatment decreases from 100% to 0% during the first 6 months in 89.0%, and during 9 months - in 66.0% of patients. Progression of the disease, after surgery and withdrawal of a-GnRH, with a 3-month course occurred - after 3 months - in 45.0%, with a 6-month course - after 9 months - in 33.0%, with a 9-month course - after 12 months - in 12.0% of people. Thus, the average median of the recurrence-free course was ±11.6 months.

CONCLUSION

Conclusions: The most effective hormone therapy in patients with HRT before and after surgical treatment is therapy with drugs of the α-¬HnRH group, courses of at least 6 months.

A NEW APPROACH TO ASSISTED REPRODUCTIVE TECHNOLOGIES PREPARATION IN WOMEN WITH ENDOMETRIOSIS ASSOCIATED INFERTILITY USING PROBIOTICS

OBJECTIVE

Aim: To examine the expression Nlrp3-inflammasome in the blood of women with endometriosis-associated infertility using assisted reproductive technologies with included probiotic and estimate a new approach with included probiotic for preparation to assisted reproductive technologies.

PATIENTS AND METHODS

Materials and methods: For the purpose of the research we examined 30 infertile women. Control group consisted of 10 women with tubal infertility due to an inflammatory process in the anamnesis, in whom, as a result of a complex clinical and laboratory examination, no other diseases were detected and in terms of their health they could be equated with practically healthy women (age from 21 to 42 years, the average age was 29.75 years) and who did not take probiotic. The main group consists from 20 women with external genital endometriosis were included in assisted reproductive technologies. Patients from main group took probiotic produced by Unic Biotech Ltd, India. 1 tablet twice a day with 10×109 Lactobacillus during 1 month in complex preparation (treatment) before assisted reproductive technologies. The indices of Nlrp3 - Inflammasome determined before and after preparation. The study was performer in Bukovinian State Medical University and Centre of Reproductive Medicine. To analyze the expression of the NLPP3-inflammasome gene and determine the relative normalized expression of NLPP3 mRNA, we used the polymerase chain reaction with reverse transcription in real time (RT-PCR). The object for molecular genetic studies by the RT-PCR method was the fraction of mononuclear cells isolated from the whole blood of patients with endometriosis. The value of p (authenticity difference) was determined by Student's table-Fischer. Differences between contrasting averages were considered significant at p <0.05.

RESULTS

Results: Analized the results of our research stated that in main group expression of Nlrp-3 inflammasome was 24,43, which is significantly higher than after preparation (0,70 accordingly). In control group expression of Nlrp3-inflammasome was 0,54. Expression of Nlrp-3 inflammasome increased in patients before preparation more than 34 times compare with patients after preparation accordingly.

CONCLUSION

Conclusions: consequently, after using probiotic, the increased level of Nlrp3-inflammasome sharply decreases, indicating the effectiveness and the possibility of use in the programme for assisted reproductive technologies preparation.
