Abstract
BACKGROUND Recurrent pregnancy loss (RPL) is a common pregnancy complication that brings great pain to pregnant women and their families. Genetic factors are an important cause reason of RPL. However, clinical research on monogenic diseases with recurrent miscarriage is insufficient. CASE PRESENTATION Here we reported a Chinese family with RPL and genetic analysis of the abortion and parents. A paternally inherited heterozygous missense variant c.1415T > G (p.V472G) and a maternally inherited heterozygous nonsense variant c.2314del (p.M772*) in TMEM67 gene were identified by trio-exome sequencing. c.2314del (p.M772*) generated a premature stop codon and truncated protein, was classified as "pathogenic". c.1415T > G (p.V472G) located in extra-cellular region, was classified as "likely pathogenic". Biallelic variants in TMEM67 gene cause lethal Meckel syndrome 3, consistent with the proband's prenatal phenotype. CONCLUSION The current study of the Chinese family expands the pathogenic variant spectrum of TMEM67 and emphasizes the necessity of exome sequencing in RPL condition.

Type and Location of Adenomyosis in Women with Recurrent Pregnancy Loss: A Transvaginal Ultrasonographic Assessment. Reprod Sci 2024:10.1007/s43032-024-01541-8. [PMID: 38619796 DOI: 10.1007/s43032-024-01541-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2023] [Accepted: 04/02/2024] [Indexed: 04/16/2024]
Abstract
The current knowledge on adenomyosis as a risk factor for RPL is very scant. Overall 120 women were included in this retrospective observational study. They were divided in three groups each of which consisted of 40 subjects: Group 1: women with RPL who were diagnosed to have adenomyosis on transvaginal ultrasound (TVS); Group 2: patients with RPL without ultrasonographic findings of adenomyosis; Group 3: patients with ultrasound diagnosis of adenomyosis without RPL and at least one live birth pregnancy. The copresence of endometriosis was also investigated. Among women with RPL, patients with adenomyosis (Group 1) had higher number of pregnancy losses (p = 0.03) and lower age at first pregnancy loss (p = 0.03) than women without adenomyosis (Group 2). Moreover, they had more frequently primary RPL (p = 0.008). Adenomyosis of the inner myometrium was found more frequently (p = 0.04) in patients of Group 1 than in patients of Group 3 in which adenomyosis was mainly in the outer myometrium (p= 0.02). No differences were found in the severity of adenomyosis between these two groups of women. TVS findings for endometriosis were observed more frequently in women with adenomyosis without RPL (Group 3) than in the other two groups of patients. Adenomyosis can be a factor involved in RPL. Differences in adenomyosis localization are associated with different risks for RPL. Patients with RPL should be investigated for the presence of adenomyosis and also for the type and localization of the disease in the different myometrial layers.

Abstract
Multiple factors contribute to recurrent pregnancy loss (RPL). This review highlights the latest international guidelines for RPL workup, including immunological testing, by the American Society for Reproductive Medicine (ASRM), the European Society of Human Reproduction and Embryology (ESHRE), and the Royal College of Obstetricians and Gynaecologists (RCOG). These three societies recommend testing for antiphospholipid syndrome. ESHRE and RCOG also recommend thyroid peroxidase antibody testing, whereas ASRM does not. All guidelines advise against testing of natural killer cells, cytokines, antinuclear antibodies, human leukocyte antigen (HLA) compatibility, anti-HLA antibodies, and anti-sperm antibodies. However, when following ASRM, ESHRE or RCOG diagnostic guidelines, over 50% of cases have no identifiable cause. Genetic testing of products of conception (POC) can improve our understanding of unexplained RPL as aneuploidy is a common cause of RPL. Based on studies reporting results from chromosomal microarray analysis (CMA) of POC, we propose a novel algorithm for RPL evaluation. The algorithm involves following evidence-based societal guidelines (published by ASRM, ESHRE, or RCOG), excluding parental karyotyping, in combination with CMA testing of miscarriage tissue. When utilizing this new evaluation algorithm, the number of unexplained cases of RPL decreases from over 50% to less than 10%. As a result, most patients are provided an explanation for their loss and healthcare costs are potentially reduced. Patients with an otherwise negative workup with euploid POC, are classified as "truly unexplained RPL". These patients are excellent candidates for enrollment in randomized, controlled trials examining novel immunological testing and treatment protocols.

Abstract
CONTEXT Implementation of pre-conception care units is still very limited in Italy. Nowadays, the population's awareness of the reproductive risks that can be reduced or prevented is very low. Purpose and main findings: We presented a new personalized multidisciplinary model of preconception care aimed at identifying and possibly reducing adverse reproductive events. We analyzed three cohorts of population: couples from the general population, infertile or subfertile couples, and couples with a previous history of adverse reproductive events. The proposal involves a deep investigation regarding family history, the personal histories of both partners, and reproductive history. PRINCIPAL CONCLUSIONS Preconception care is still neglected in Italy and under-evaluated by clinicians involved in natural or in vitro reproduction. Adequate preconception counseling will improve maternal and fetal obstetrical outcomes.

Liu Z, Wang KH. Effect of basal luteinizing hormone (bLH) level on in vitro fertilization/intra-cytoplasmic injections (IVF/ICSI) outcomes in polycystic ovarian syndrome (PCOS) patients. BMC Pregnancy Childbirth 2023; 23:618. [PMID: 37644399 PMCID: PMC10466855 DOI: 10.1186/s12884-023-05944-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Accepted: 08/22/2023] [Indexed: 08/31/2023] Open
Abstract
OBJECTIVE To evaluate the effect of basal luteinizing hormone (bLH) levels on In Vitro Fertilization/Intra-Cytoplasmic Injections (IVF/ICSI) outcomes in polycystic ovary syndrome (PCOS). METHODS A total of 256 PCOS patients who underwent IVF/ICSI treatment in our center from January 2018 to January 2022 were analyzed retrospectively. The patients were based on the third quartile (12.455) of the basal LH value was taken as the cut-off value and was divided into high and low LH group: high LH group (LH ≥ 12.455 IU / L) and low LH group (LH < 12.455 IU / L) and the OC group was pretreated with oral contraceptives. The outcomes in ovulation induction and embryo transfer cycles of the three groups were then compared. In addition, factors influencing the number of good quality embryos and the early onset LH peak were analyzed. RESULTS Ages, infertility duration, body mass index (BMI), and basal follicle-stimulating hormone (FSH), and progesterone (P), testosterone (T) levels were not significantly different among the three groups (p > 0.05). However,there were significant differences in basal LH and basal E2 between low LH group and high LH group, and there were significant differences in basal LH between high LH group and OC group (p < 0.05). LH on the antagonist day was significantly different between low LH group and high LH group and between high LH group and OC group (p < 0.05). LH on the hCG (human Chorionic Gonadotropin) day there were significant differences between low LH group and OC group, high LH group and OC group (p < 0.05). The Mode of triggering between the three groups had significant differences between the two groups (p < 0.05). In addition, the number of days from gonadotropin (Gn) initiation to antagonist addition were significantly different among the three groups (p < 0.05). In addition, total Gn doses,the number of oocytes retrieved, the number of Gn days, 2pronucleus (2PN) numbers, number of good quality embryos, and number of high risk OHSS (Ovarian Hyper-stimulation Syndrome), cases with OHSS occurrences were not significantly different among the three groups (p > 0.05). Moreover, the cycle and clinical pregnancy outcomes and the cumulative clinical pregnancy rate and the cumulative live birth rate were not significantly different among the three groups (p > 0.05). LH levels on the day of antagonist addition affected the number of good-quality embryos (B < 0, p < 0.05). However, LH levels on the day antagonist was added were not significantly correlated with basal LH levels (Pearson correlation coefficient = 0.259), the ROC curve was constructed for the logistic prediction model of the early onset LH peak, and the AUC value was 0.747, indicating that the logistic combined model we constructed had a good ability to predict the early onset LH peak. CONCLUSION Basal LH levels do not affect the pregnancy outcomes in PCOS patients after antagonist protocols. Besides, LH levels on the day of antagonist addition affect the number of good quality embryos for PCOS patients undergoing IVF /ICSI.
