A new insight on evaluation of the fertility and pregnancy outcome in patients with primary Sjögren syndrome: a propensity score matched study in multi-IVF centers

BackgroundPrimary Sjögren syndrome (pSS) is often related to adverse neonatal outcomes. But it’s currently controversial whether pSS has an adverse effect on female fertility and clinical pregnancy condition. More importantly, it’s unclear regarding the role of pSS in oocyte and embryonic development. There is a lack of comprehensive understanding and evaluation of fertility in pSS patients.ObjectiveThis study aimed to investigate oocyte and embryonic development, ovarian reserve, and clinical pregnancy outcomes in Primary Sjögren syndrome (pSS) patients during in vitro fertilization (IVF) treatment from multi-IVF centers.MethodsWe performed a muti-central retrospective cohort study overall evaluating the baseline characteristics, ovarian reserve, IVF laboratory outcomes, and clinical pregnancy outcomes between the pSS patients and control patients who were matched by Propensity Score Matching.ResultsFollowing PSM matching, baseline characteristics generally coincided between the two groups. Ovarian reserve including anti-müllerian hormone (AMH) and antral follicle counting (AFC) were significantly lower in the pSS group vs comparison (0.8 vs. 2.9 ng/mL, P < 0.001; 6.0 vs. 10.0, P < 0.001, respectively). The pSS group performed significant reductions in numbers of large follicles, oocytes retrieved and MII oocytes. Additionally, pSS patients exhibited obviously deteriorate rates of oocyte maturation, 2PN cleavage, D3 good-quality embryo, and blastocyst formation compared to comparison. As for clinical pregnancy, notable decrease was found in implantation rate (37.9% vs. 54.9%, P = 0.022). The cumulative live birth rate (CLBR) following every embryo-transfer procedure was distinctly lower in the pSS group, and the conservative and optimal CLBRs following every complete cycle procedure were also significantly reduced in the pSS group. Lastly, the gestational weeks of the newborns in pSS group were distinctly early vs comparison.ConclusionPatients with pSS exhibit worse conditions in terms of female fertility and clinical pregnancy, notably accompanied with deteriorate oocyte and embryo development. Individualized fertility evaluation and early fertility guidance are essential for these special patients.

Personalized embryo transfer guided by rsERT improves pregnancy outcomes in patients with repeated implantation failure

IntroductionEmbryo implantation requires synchronous communication between the embryo and maternal endometrium. Inadequate maternal endometrial receptivity is one of the principal causes for embryo implantation failure [especially repeated implantation failure (RIF)] when biopsied good-quality euploid embryos are transferred. An RNA-seq-based endometrial receptivity test (rsERT) was previously established to precisely guide successful embryo implantation. In this study, we aimed to evaluate the effect of personalized embryo transfer (pET) via rsERT on the clinical outcomes in patients with RIF.MethodsA total of 155 patients with RIF were included in the present retrospective study and were divided into two groups: 60 patients who underwent rsERT and pET (Group rsERT) and 95 patients who underwent standard frozen embryo transfer (FET) without rsERT (Group FET). Reproductive outcomes were compared for patients who underwent rsERT-guided pET and standard FET.ResultsForty percent (24/60) of the patients who underwent rsERT were receptive, and the remaining 60% (36/60) were non-receptive. The positive human chorionic gonadotropin (β-hCG) rate (56.3% vs. 30.5%, P = 0.003) and clinical pregnancy rate (43.8% vs. 24.2%, P = 0.017) were significantly higher in Group rsERT patients than in FET group patients. Additionally, Group rsERT patients also showed a higher implantation rate (32.1% vs. 22.1%, P = 0.104) and live birth rate (35.4% vs. 21.1%, P = 0.064) when compared with FET patients, although without significance. For subpopulation analysis, the positive β-hCG rate, clinical pregnancy rate, implantation rate, and live birth rate of receptive patients were not statistically significant different from those of non-receptive patients.ConclusionsThe rsERT can significantly improve the pregnancy outcomes of RIF patients, indicating the clinical potential of rsERT-guided pET.

Pregnancy outcomes and complications after renal transplantation

Introduction. Chronic kidney disease (CKD) in pregnancy poses certain risks of both gestational complications and adverse perinatal outcomes, which increase with the decline of renal function.Aim to access pregnancy outcomes in patients who underwent nephrotransplantation.Materials and methods. Retrospective study of pregnant women who gave birth at Academician V.I. Kulakov National Medical Research Center for Obstetrics, Gynecology and Perinatology in the period from 2005 to 2021: 102 pregnancies in 97 patients were analyzed: five recipients had two successful pregnancies.Results. The average age of pregnant women was 31 ± 4.03 years. In equal proportions, patients underwent related or cadaveric kidney transplantation – 52% (n = 53) and 48% (n = 49) of cases, respectively. The average delivery time was 35.5 ± 2.7 weeks. The average weight of newborns was 2545 ± 655 grams. Premature birth (PB) occurred in 47.1%, the average period of birth was 33.4 ± 2.87 weeks, of which early birth (&lt;32 weeks) was 22.5%. The average period of pregnancy after transplantation was 5 ± 3.31 (1–18) years, this period was not associated with obstetric complications or deterioration of graft function. A significant increase in the following parameters was noted during pregnancy: serum creatinine level (p = 0.006), proteinuria (p = 0.003). The glomerular filtration rate also decreased significantly by the end of pregnancy (p = 0.011). Preeclampsia was the leading cause of decreased graft function during pregnancy (32.4%).Conclusions. In general, pregnancy outcomes after nephrotransplantation are favorable, but there is an increased risk of preeclampsia, preterm birth, including operative delivery, urinary tract infection and anemia.

The safety and efficacy of tumor necrosis factor-alpha inhibitor on pregnancy outcomes in patients with unexplained recurrent miscarriage

ObjectivesAlthough tumor necrosis factor-alpha inhibitor (TNFi) treatment may improve pregnancy outcomes in unexplained recurrent miscarriage (URM) patients, evidence for its efficacy and safety is still insufficient. The goal of this study was to evaluate the efficacy and safety of TNFi on pregnancy outcomes in patients with URM. MethodsThis retrospective study was conducted at a single institution in China, involving 121 patients treated with TNFi for URM from 2019 to 2022. Patients enrolled were divided into treatment group (receiving TNFi and heparin therapy) and control group (receiving heparin therapy). The outcome variables were the 24-week live birth rate, miscarriage rate, ectopic pregnancy rate, neonatal outcomes, and adverse events. ResultsIn our study, patients receiving TNFi treatment exhibited a significant increase in live birth rates, achieving 71.2 % compared to the 50.9 % observed in the control group (OR 2.507, 95 % CI: 1.127–5.579). Concurrently, there was a discernible reduction in the miscarriage rate within the TNFi-treated group, marking 24.2 %, in contrast to 43.6 % in the control group (OR 0.387, 95 % CI: 0.170–0.884). Subgroup analyses further illuminated that those under the age of 35 benefitted remarkably from TNFi treatment, with live birth rates soaring to 62.5 % (OR 2.525, 95 % CI: 1.041–6.125). For patients with a history of two miscarriages, the TNFi regimen significantly augmented the live birth rate to 58.9 % (OR 3.044, 95 % CI: 1.039–8.921). Patients with a normal weight range registered a 58.4 % live birth rate post-TNFi treatment (OR 4.261, 95 % CI: 1.539–11.397). Notably, an evident interaction between BMI and TNFi treatment was identified, suggesting a potential modulatory role of BMI on the therapeutic efficacy of TNFi. About safety assessments, neither the TNFi-treated group nor the control manifested any significant disparities in liver function abnormalities, platelet count anomalies, or other pregnancy-related complications. ConclusionsTNFi, alongside basic therapy, notably enhances the live birth rate in URM patients under 35, with two prior miscarriages or a normal BMI, without increasing adverse event risk. Further prospective studies are essential to validate these observations.

Eculizumab for paroxysmal nocturnal hemoglobinuria: Two cases of successful pregnancy outcomes

Key Clinical MessageParoxysmal nocturnal hemoglobinuria is a rare disease with the incidence ranging from 0.08 to 0.57 per 100,000 person‐years. Up to 25% of cases in women are detected during pregnancy. We report two cases of successful pregnancy outcomes in patients treated with eculizumab, pointing out the importance of interdisciplinary approach in these high‐risk pregnancies.

Effect of baseline prolactin levels on the pregnancy outcomes after fresh embryo transfer.

There is clinical disagreement on whether to treat hyperprolactinemia with medication before embryo transfer. The aim of this study is to identify the impact of basal prolactin (PRL) levels on pregnancy outcomes in fresh embryo transfer cycles. This retrospective study involved 2,648 women who underwent basal PRL level testing and fresh embryo transfer between January 2015 and December 2020 at our Hospital's Department of Assisted Reproduction. Basal PRL levels can be classified into three categories:<30 (n=2339), 30‑60 (n=255), and ≥60 (n=54) µg/l. Pregnancy outcome was defined as the primary outcome measure, and the live birth rate was defined as the second outcome measure. Subsequently, univariate and multivariable logistic regression analysis was used to reveal the association between basal PRL levels and pregnancy outcomes after considering several potential confounding factors. Elevated basal PRL levels were found not a risk factor for pregnancy outcomes in patients receiving good-quality embryo transfer (p>.05). For pregnancy or not, female age (OR: 1.03; 95% CI: 1.01-1.05), embryos transferred (OR: 0.52; 95% CI: 0.41-0.65), and normal fertilization rate (OR: 0.68; 95% CI: 0.48-0.97) were found to be an independent risk factor. For ongoing pregnancy or not, female age (OR: 1.07; 95% CI: 1.03-1.11), embryos transferred (OR: 0.57; 95% CI: 0.37-0.88), and menstrual cycle (OR: 1.76; 95% CI: 1.22-2.54) were also independent risk factors. There is no adverse impact on pregnancy outcomes during embryo transfer cycles with good-quality embryos when PRL levels are elevated.

COVID-19-associated morbidity and mortality outcomes in pregnant patients admitted to intensive care unit

Background: Our study aimed to evaluate the clinical characteristics and maternal-fetal outcomes of pregnant women admitted to the ICU due to COVID-19 pneumonia. Materials and Methods: Demographic data, presenting complaints, laboratory values, pregnancy outcomes, delivery method, and ICU mortality were recorded. Results: A total of 10 pregnant patients were admitted to the intensive care unit of our hospital due to SARS-COV-2 infection during the 2-year period. Arterial blood oxygen saturation values measured at admission to the ICU were higher in the surviving patients. Six of the 10 patients died. Only one of the 7 patients requiring invasive mechanical ventilation survived. Conclusions: We found that COVID-19-infected pregnant women with severe symptoms have several maternal morbidities and poor obstetric outcomes, such as prolonged intensive care unit stay, increased mortality, neonatal deaths, and caserean section.

Pregnancy Outcomes in Patients with Prosthetic Heart Valves in Saudi Arabia

Background: Pregnancies in women with heart prostheses are high-risk pregnancies with increased maternal and fetal adverse outcomes. Advances in prosthetic heart valve design and anticoagulation have improved these outcomes over the past decades. Objectives: To study the pregnancy outcomes in pregnancies with heart prostheses and to compare these outcomes between mechanical and biosynthetic heart prostheses in Saudi patients. Methods: In this single centered retrospective study conducted at King Saud Medical City (KSUMC) between January 2011 and February 2020, we have reviewed all pregnant women’s heart prostheses. Fetal and maternal data were obtained, and outcomes were compared between pregnancies with mechanical heart prostheses and bioprostheses. Results: A total of 111 pregnancies were reviewed. A total of 51.4% of pregnancies had bioprostheses, 48.6% had mechanical prostheses, and 64.0% of participants were obese. The majority of the participants had a parity in the range of 2-9 (N=107, 96.4%). The most frequent type of rheumatic heart disease was mitral regurgitation (N=49, 44.1%), followed by mitral stenosis (N=32, 28.8%). There was no maternal mortality and no structural valve failure. There was a high rate of hospital admission in both groups, up to 55% of pregnancies. The rates of abortion, postpartum hemorrhage and transfusions were higher than those in general pregnancies; however, there was no difference in maternal and fetal complications between the two types of prostheses, i.e., bioprostheses and mechanical. Conclusion: Although women with prosthetic heart valves have higher rates of adverse outcomes, they generally tolerate pregnancy well. There was no difference in adverse outcomes between bioprosthetic and mechanical prostheses

Effects of individual drug and combination antiretroviral therapy on trophoblast proliferation

BackgroundCombination antiretroviral therapy (cART) has been reported to reduce perinatal transmission of human immunodeficiency virus (HIV) and improve maternal survival outcomes. Recent studies have associated in-utero exposure to cART drugs with adverse outcomes such as pre-eclampsia, preterm delivery, low birth weight and small-for-gestational-age births. However, the exact molecular mechanisms underlying cART-induced adverse pregnancy outcomes remain poorly defined. ObjectivesTo investigate the effects of cART drugs on trophoblast proliferation in the HTR-8/SVneo cell line. Study designHTR-8/SVneo cells were exposed to tenofovir (0.983–9.83 µM), emtricitabine (0.809–8.09 µM) and efavirenz (0.19–1.09 µM), the individual drugs of the first-line single tablet cART regimen termed ‘Atripla’, and zidovudine (1.12–1.12 µM), lamivudine (0.65–6.5 µM), lopinavir (0.32–3.2 µM) and ritonavir (0.69–6.9 µM), the individual drugs of the second-line single tablet cART regimen termed ‘Aluvia’. The cells were treated for 24, 48, 72 and 96 h, and trophoblast proliferation was assessed using a colorimetric 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltretrazolium bromide assay. ResultsTwo-way analysis of variance showed a significant dose-dependent decrease (p < 0.05) in trophoblast proliferation in response to individual and combined drug components of first- and second-line antiretroviral therapy. ConclusionsFirst- and second-line cART drugs inhibit trophoblast proliferation, and may contribute to placenta-mediated adverse pregnancy outcomes in patients with HIV.

Effects of magnesium sulfate combined with labetalol on inflammatory stress and pregnancy outcome of patients with gestational hypertension.

Gestational hypertension (GH) is a common disorder during pregnancy that can cause adverse pregnancy outcomes. In the present study, magnesium sulfate (MgSO4) combined with labetalol was used for clinical treatment. Randomized controlled trial was conducted in 100 patients with GH, documented in the Department of Obstetrics and Gynecology (Taicang TCM Hospital) grouped into the experimental (Expt) and control (Ctrl) groups (n=50 cases/group). The Ctrl group was treated with MgSO4, whereas the Expt group was treated with MgSO4 + labetalol. The systolic blood pressure (SBP) and diastolic blood pressure (DBP) in the Expt group were not significantly different from those in the Ctrl group (P>0.05). By contrast, the SBP and DBP were significantly lower after treatment than those before treatment in both groups (P<0.05). Whole blood viscosity, plasma viscosity and hematocrit were significantly lower in the Expt group compared with those in the Ctrl group after treatment (P<0.05). High mobility group box-1 protein, homocysteine and serum cystatin C levels in the Expt group were also markedly lower than those in the Ctrl group after treatment (P<0.05). In the Expt group, the rate of spontaneous vaginal delivery was much higher, whereas the rates of cesarean section and postpartum hemorrhage were markedly lower than those in the Ctrl group (P<0.05). The occurrence of fetal intrauterine distress, placental abruption, neonatal asphyxia, premature birth and neonatal death were also significantly lower in the Expt group than those in the Ctrl group (P<0.05). In conclusion, MgSO4 + labetalol could improve inflammatory stress and the hemodynamics of patients with GH, and may have a marked antihypertensive effect. Thus, it may improve pregnancy outcome and reduce perinatal complications.

OA22 Pregnancy in connective tissue diseases: a 30 year follow-up study of 465 pregnancies from a Spanish monocentric registry

Abstract Background/Aims Pregnancy in patients with connective tissue diseases (CTDs) are known to be at high risk for the occurrence of adverse pregnancy outcomes. We aimed to evaluate pregnancy outcomes in patients with systemic lupus erythematosus (SLE), systemic sclerosis (SSc), primary Sjögren’s syndrome (pSS) and undifferentiated connective tissue disease (UCTD). Methods A retrospective and descriptive study was conducted from 1990 to 2020. All data were collected from the medical records of women of childbearing age with SLE, SSc, SS and UTCD enrolled in our clinic at the time of their pregnancy and childbirth. The obstetric, maternal and fetal outcomes were collected and compared regarding diagnosis and adverse outcomes. Results The study group included 295 patients: 125 patients (42%) with SLE; 50 patients (17%) with SSc; 80 patients (27%) with pSS; 40 patients (14%) with UCTD. A total of 465 pregnancies were registered. The mean age at delivery was 31.5±8.5 years and the mean duration of disease was 7.2±5.6 years. Pregnancy loss occurred in 21% of patients, live births in 66% of pregnancies, preterm delivery in 8%, postpartum haemorrhage in 6%, preeclampsia in 5%, placental abnormalities in 4%, ectopic pregnancy in 3%, and premature rupture of membranes in 2%. Treatment with hydroxychloroquine (HCQ) was received in 115 pregnancies in SLE (59%), 21 pregnancies in SSc (24%) 62 pregnancies in pSS (52%) and 32 pregnancies in UCTD (49%). Exposure to corticosteroids and biologics during pregnancy was 23 (18.4%), 6 (12%), 15 (19%) and 3 (7.5%), respectively. Patients with SLE had a higher risk of fetal morbidity, including abortion (p = 0.03), mean abortion rate (p = 0.03), preeclampsia (p = 0.04), ectopic pregnancy (p = 0.03), preterm delivery (p = 0.02) and postpartum haemorrhage (p = 0.01) than patients without SLE. The multivariate model found an association between unfavourable pregnancy outcomes and disease activity (OR 2.4; 95% CI 1.3-7.2; p 0.003), whilst HCQ during pregnancy (OR 0.23; 95% CI 0.03-0.82) had a protective effect. Conclusion 66% of pregnancies in patients with autoimmune diseases resulted in live births. Patients with SLE had higher rates of fetal and maternal morbidity than SSc, pSS and UCTD. Disease activity was associated with unfavourable pregnancy outcomes. Exposure to HCQ had a protective effect during pregnancy. Disclosure C. Sieiro Santos: None. P. Pérez García: None. J.

The Inflammatory State of Follicular Fluid Combined with Negative Emotion Indicators can Predict Pregnancy Outcomes in Patients with PCOS.

Polycystic ovary syndrome (PCOS) is a complex endocrine disorder syndrome with an incidence of 6% to 10% in women of reproductive age. Women with PCOS not only exhibit abnormal follicular development and fertility disorders, but also have a greater tendency to develop anxiety and depression. Our aim was to evaluate the ability of inflammatory factors in follicular fluid to predict embryonic developmental potential and pregnancy outcome and to construct a machine learning model that can predict IVF pregnancy outcomes based on indicators such as basic sex hormones, embryonic morphology, the follicular microenvironment, and negative emotion. In this study, inflammatory factors (CRP, IL-6, and TNF-α) in follicular fluid samples obtained from 225 PCOS and 225 non-PCOS women were detected via ELISA. For patients with PCOS, the levels of CRP and IL-6 in the follicular fluid in the pregnant group were significantly lower than those in the nonpregnant group. For non-patients with PCOS, only the level of IL-6 in the follicular fluid was significantly lower in the pregnant group than in the nonpregnant group. In addition, for both PCOS and non-patients with PCOS, compared with those in the pregnant group, patients in the nonpregnant group showed more pronounced signs of anxiety and depression. Finally, the factors that were significantly different between the two subgroups (pregnancy and nonpregnancy) of patients with or without PCOS were identified by an independent sample t test first and further analysed by multilayer perceptron (MLP) and random forest (RF) models to distinguish the two clinical pregnancy outcomes according to the classification function. The accuracy of the RF model in predicting pregnancy outcomes in patients with or without PCOS was 95.6% and 91.1%, respectively. The RF model is more suitable than the MLP model for predicting pregnancy outcomes in IVF patients. This study not only identified inflammatory factors that can affect embryonic development and assessed the anxiety and depression tendencies of PCOS patients, but also constructed an AI model that predict pregnancy outcomes through machine learning methods, which is a beneficial clinical tool.

Uterine infusion strategies for infertile patients with recurrent implantation failure: a systematic review and network meta-analysis

BackgroundIntra-uterine infusion treatments were reported to be beneficial to embryo implantation and pregnancy outcomes, and considered as potential therapies for infertile patients with recurrent implantation failure (RIF). Nevertheless, their efficiencies were controversial and there lack of consensus on which intrauterine treatment is the most effective.MethodsAll prospective trials (in Chinese or English) were searched in Databases PubMed, Cochrane, Web of Science, and CNKI from July 2013 to July 2023. We included studies that investigated various uterine infusions, including chorionic gonadotropin, granulocyte colony-stimulating factor, monocytes, platelet-rich plasma, etc. during IVF treatment and reported subsequent pregnancy outcomes.ResultsWe finally included 56 researches, including 40 randomized controlled trials, 14 non-randomized controlled trials, and 3 prospective cohort studies. This study included a total of 11 uterine perfusion methods: Placebo, Human Chorionic Gonadotropin (HCG), Granulocyte Colony-Stimulating Factor (G-CSF), platelet-rich plasma (PRP), Peripheral Blood Mononuclear Cell (PBMC), Growth hormone (GH), dexamethasone (DEX), Embryo culture supernatant (ESC), PRP combined with G-CSF (PRP + G-CSF), RPR combined with subcutaneous injection of G-CSF (RPR + G-CSFsc), G-CSF combined with subcutaneous injection of AXaIU (G-CSF + AXaIUsc). Intrauterine infusion of HCG, PBMC, G-CSF, and PRP significantly improves pregnancy outcomes in patients with repeated implantation failure compared with blank controls or placebo, and PRP improved the clinical pregnancy and live birth most. GH and ESC infusion might improve the pregnancy outcomes, but uterine infusion of DEX was shown with high miscarriage. The combination therapy did not show a significant advantage over the mono-therapy.ConclusionsIntrauterine infusion of HCG, PBMC, G-CSF, and PRP are promising strategies for improving pregnancy outcomes for infertile patients with recurrent implantation failure. Among these treatments, PRP may be the best. More researches are required to explore the effect of drug combinations and less commonly used drugs as well.Trial registrationOur study was registered in PROSPERO and the ID was CRD42023467188.

Risk Factors for Adverse Pregnancy Outcomes in Patients with Antiphospholipid Syndrome

Risk Factors for Adverse Pregnancy Outcomes in Patients with Antiphospholipid Syndrome

Effect of extended precision nursing on neurobehavioral function and pregnancy outcome in patients with threatened abortion.

This study aimed to assess the impact of continuous precision nursing on neurobehavioral function and pregnancy outcomes in patients experiencing threatened abortion. A total of 130 patients with early threatened abortion admitted to our hospital between October 2020 and January 2023 were selected and categorized into 2 groups based on intervention methods. The control group received routine nursing intervention, whereas the observation group received continuous precision nursing intervention. Changes in affective status scores, SF-36 scores, knowledge mastery scores, and satisfaction scores in the neurobehavioral function test before and after intervention were recorded in both groups. Additionally, pregnancy outcomes, obstetric adverse reaction rates, and neonatal conditions were documented. Following intervention, scores for tension-anxiety, depression-dejection, anger-hostility, vigor-activity, fatigue-inertia, and confusion-bewilderment gradually decreased in both groups, with significantly lower scores observed in the observation group compared to the control group (P < .05). SF-36 scores in 8 dimensions, including physical functioning, role-physical, bodily pain, and overall health rating, showed a gradual increase in both groups, with the observation group scoring higher than the control group (P < .05). Knowledge mastery and satisfaction scores also increased significantly after intervention, with the observation group surpassing the control group (P < .05). The observation group exhibited lower rates of abortion and premature birth, along with a higher rate of full-term pregnancy compared to the control group, with statistically significant differences (P < .05). Furthermore, the observation group displayed lower rates of adverse reactions and low birth weight infants, with significant differences compared to the control group (P < .05). No significant differences were observed in neonatal mortality and neonatal intensive care unit transfer rates between the observation and control groups (P > .05). Continuous precision nursing contributes to improved pregnancy outcomes for patients with threatened miscarriage within the first 12 weeks of pregnancy. This comprehensive care approach is associated with enhanced knowledge retention, protection of neurological function, and an overall improvement in quality of life.

Reproductive outcomes of dual trigger therapy with GnRH agonist and hCG versus hCG trigger in women with diminished ovarian reserve: a retrospective study

BackgroundDiminished ovarian reserve (DOR) is one of the obstacles affecting the reproductive outcomes of patients receiving assisted reproductive therapy. The purpose of this study was to investigate whether dual trigger, including gonadotropin‐releasing hormone agonist (GnRHa) and human chorionic gonadotropin (hCG), can improve pregnancy outcomes in patients with DOR undergoing in vitro fertilization (IVF) cycles using mild stimulation protocols.MethodsA total of 734 patients with DOR were included in this retrospective study. Patients were divided into a recombinant hCG trigger group and a dual trigger group (hCG combined with GnRHa) according to the different trigger drugs used. The main outcome measures included the number of oocytes retrieved, the fertilization rate, the number of transferable embryos, the implantation rate, the clinical pregnancy rate, the miscarriage rate, the live birth rate (LBR), and the cumulative live birth rate (CLBR). Generalized linear model and logistic regression analyses were performed for confounding factors.ResultsThere were 337 cycles with a single hCG trigger and 397 cycles with dual trigger. The dual trigger group demonstrated significantly higher numbers of retrieved oocytes [3.60 vs. 2.39, adjusted β = 0.538 (0.221–0.855)], fertilized oocytes [2.55 vs. 1.94, adjusted β = 0.277 (0.031–0.523)] and transferable embryos [1.22 vs. 0.95, adjusted β = 0.162 (-0.005–0.329)] than did the hCG trigger group, whereas no significant difference in the fertilization rate was observed between the two groups. Moreover, the embryo transfer cancellation rate (35.5% vs. 43.9%) was obviously lower in the dual trigger group. Among the fresh embryo transfer cycles, the implantation rate, clinical pregnancy rate, miscarriage rate and live birth rate were similar between the two groups. After controlling for potential confounding variables, the trigger method was identified as an independent factor affecting the number of oocytes retrieved but had no significant impact on the CLBR.ConclusionsDual triggering of final oocyte maturation with hCG combined with GnRHa can significantly increase the number of oocytes retrieved in patients with DOR but has no improvement effect on the implantation rate, clinical pregnancy rate or LBR of fresh cycles or on the CLBR.

Comparing pregnancy outcomes in patients with Systemic Lupus Erythematosus (SLE) and Undifferentiated Connective Tissue Disease (UCTD): a descriptive cohort study

BackgroundFemales diagnosed with systemic lupus erythematosus (SLE) face an elevated risk of adverse pregnancy outcomes (APOs). However, the evidence regarding whether a similar association exists in patients with undifferentiated connective tissue disease (UCTD) is inconclusive. MethodsWe conducted a retrospective review (2006–2019) of pregnancy outcomes among patients with SLE (n = 51) and UCTD (n = 20) within our institution. We examined the occurrence of various APOs, encompassing miscarriage, stillbirth, termination, preterm birth, pre-eclampsia, eclampsia, HELLP syndrome, intrauterine growth restriction, abruption placentae, congenital heart block, or other cardiac abnormalities. ResultsThe mean age at pregnancy was 35 ± 7.0 years for patients with SLE and 35 ± 6.8 years for those with UCTD (p = 0.349). The proportion of Caucasian women was 47% in SLE and 80% in UCTD. Pregnancies in both groups were planned (81% in SLE and 77% in UCTD), and patients presented with inactive disease at conception (96% in SLE and 89% in UCTD). Hydroxychloroquine at conception was utilized by 86% of women with SLE, in contrast to 36% in the UCTD group. Both, SLE and UCTD cohorts exhibited low rates of disease flares during pregnancy and/or puerperium (14% vs. 10%). The incidence of APOs was 15.6% in SLE patients compared to 5% in those with UCTD (Risk difference 19.5%; 95% confidence interval: −3.9 to 43.1; p = 0.4237). ConclusionOur study underscores the importance of strategic pregnancy planning and the maintenance of appropriate treatment throughout pregnancy to ensure optimal disease management and minimize adverse outcomes in both SLE and UCTD pregnancies.

Semi-quantitative metalloproteinase-8 rapid test for the prediction of adverse pregnancy outcomes in patients with preterm premature rupture of membranes

ObjectiveWe aimed to determine whether the semi-quantitative metalloproteinase-8 (MMP-8) bedside test is a worthwhile indicator in reflecting the severity of of intra-amniotic inflammation (IAI) and in predicting adverse pregnancy outcomes. Study DesignThis retrospective cohort study comprised 76 singleton-pregnant women admitted to the Seoul National University Bundang Hospital with a diagnosis of preterm premature rupture of membranes (preterm PROM) between 20 weeks 0 days and 33 weeks 6 days of gestation who underwent trans-abdominal amniocentesis to confirm intra-amniotic infection by positive results for aerobic/anaerobic bacteria, fungi, and genital mycoplasma and evaluate lung maturity. The semi-quantitative MMP-8 rapid test kit employs a colourimetric assay to quantify MMP-8 levels in amniotic fluid (AF), expressing results from 0 to 100 percent. Participants were divided into three groups: group 1, including negative MMP-8 test with colour scale of 0 % (negative, n = 17); group 2, including positive MMP-8 test with colour scale < 51 % (weak positive, n = 21); and group 3, including positive MMP-8 test with colour scale of 51 %–100 % (strong positive, n = 38). ResultsApproximately 78 % (59/76) of the participants showed a positive MMP-8 test result; all culture-proven AF samples (33.3 % [25/75]) yielded positive MMP-8 test, categorizing these patients into either group 2 or group 3. A significant trend was observed where the rate of positive culture-proven samples increased with the progression from group 1 (negative) to group 3 (strong positive). Both white blood cell counts in AF and maternal serum C-reactive protein levels were found to escalate with the progression of test results from negative to strong positive. This progression was associated with an increased risk of spontaneous preterm birth within 48 h, 7 days, and 14 days from amniocentesis and within 34 weeks of gestation. ConclusionThe more the test results progress from negative to strong positive, the shorter the interval from amniocentesis to delivery becomes, and the higher the risk of intra-amniotic infection, spontaneous preterm delivery, and other perinatal complications. This relationship highlights the critical value of the semi-quantitative MMP-8 rapid test in predicting adverse pregnancy outcomes in patients with preterm PROM.

Reproductive factors and subsequent pregnancy outcomes in patients with prior pregnancy loss

BackgroundAt present, individualized interventions can be given to patients with a clear etiology of pregnancy loss to improve the subsequent pregnancy outcomes, but the current reproductive status of the patient cannot be changed. The aim of this study was to investigate the association between female reproductive status and subsequence pregnancy outcome in patients with prior pregnancy loss (PL).MethodsA prospective, dynamic population cohort study was carried out at the Second Hospital of Lanzhou University. From September 2019 to February 2022, a total of 1955 women with at least one previous PL were enrolled. Maternal reproductive status and subsequent reproductive outcomes were recorded through an electronic medical record system and follow-up. Logistic regression was used to evaluate the association between reproductive status and the risk of subsequent reproductive outcomes.ResultsAmong all patients, the rates of subsequent infertility, early PL, late PL, and live birth were 20.82%, 24.33%, 1.69% and 50.77% respectively. In logistic regression, we found that age (OR 1.08, 95% CI 1.04–1.13) and previous cesarean delivery history (OR 2.46, 95% CI 1.27–4.76) were risk factors for subsequent infertility in patients with PL. Age (OR 1.06, 95% CI 1.03–1.10), age at first pregnancy (OR 1.06, 95% CI 1.03–1.10), BMI (OR 1.06, 95% CI 1.02–1.11), previous PL numbers (OR 1.18, 95% CI 1.04–1.57) and without pre-pregnancy intervention (OR 1.77, 95% CI 1.35–2.24) were risk factors for non-live birth. Age (OR 1.06, 95% CI 1.03–1.09), age at first pregnancy (OR 1.06, 95% CI 1.02–1.09), BMI (OR 1.07, 95% CI 1.02–1.11), previous PL numbers (OR 1.15, 95% CI 1.02–1.31) and without pre-pregnancy intervention (OR 2.16, 95% CI 1.65–2.84) were risk factors for PL.ConclusionsThe reproductive status of people with PL is strongly correlated with the outcome of subsequent pregnancies. Active pre-pregnancy intervention can improve the subsequent pregnancy outcome.Trial registrationThis study was registered in the Chinese Clinical Trial Registry with the registration number of ChiCTR2000039414 (27/10/2020).
