Laparoscopic removal of heterotopic cesarean scar pregnancy

ObjectiveTo present the laparoscopic management of heterotopic cesarean scar pregnancy and discuss other treatment options. DesignSurgical video article. The Institutional Ethics Committee approved the video reproduction. SettingTertiary referral university hospital PatientA 29-year-old woman with spontaneous heterotopic cesarean scar pregnancy presented for vaginal spotting. Ultrasound revealed two gestational sacs at 7 weeks and 6 days of gestation with fetal cardiac activity. One sac was in a normal intrauterine location and the other in a previous cesarean section scar. InterventionsScar pregnancy was excised laparoscopically while preserving intrauterine pregnancy. No additional measures were taken to reduce bleeding. The bladder was filled with 150 cc isotonic to determine its boundaries. The peritoneum was dissected away from the cervix. After removing the ectopic pregnancy material, the myometrial defect was excised. The uterine wall was closed in three layers using 2-0 V-LocTM sutures. Main outcome measuresOngoing intrauterine pregnancy after laparoscopic removal of cesarean scar pregnancy and term delivery. ResultsThe procedure was completed in 67 min. Total blood loss was <100 cc. Ongoing pregnancy follow-up was uneventful. Delivery was planned for the 37th-38th weeks. Although instructed to visit immediately after experiencing pain, the patient arrived after the 38th week and reported having pain for 2 days. During cesarean section, a rupture was observed at the previous incision site, which was fortunately incomplete. A healthy male baby (weight, 3210 g; Apgar score, 9/10) was delivered. ConclusionsThe most common approach for heterotopic scar pregnancy is embryo reduction with potassium chloride injection. However, the mass persists in the scar area, resulting in complications associated with excessive bleeding during cesarean section in approximately half cases. Moreover, almost all published cases of embryo reduction resulted in premature births before week 36. Considering the present case, laparoscopic surgery may be appropriate for managing heterotopic cesarean scar pregnancy by preserving intrauterine pregnancy.

Pregnancy and fetal outcomes following paternal exposure to glatiramer acetate

Objectives This study aimed to examine pregnancy and fetal outcomes following paternal exposure to glatiramer acetate (GA). Methods Pregnancy reports of paternal GA-exposure at time of conception from 2001 to 2022 were extracted from Teva Global Pharmacovigilance database. Pregnancy reports obtained prior to (prospective) or after (retrospective) knowledge of the pregnancy outcome were included. The primary endpoint was major congenital malformation (MCM) in the offspring according to the US Metropolitan Atlanta Congenital Defects Program (MACDP) and European Surveillance of Congenital Anomalies and Twins (EUROCAT) classification. Other pregnancy and fetal outcomes, including spontaneous abortion, pregnancy termination, fetal death, preterm birth, and low birth weight, were assessed. Results A total of 466 paternal GA-exposed pregnancies were retrieved, 232 prospective cases and 234 retrospective cases. Of 349 (74.9%) pregnancies with known outcomes, 316 (90.5%) were live births, 28 (8.0%) were spontaneous abortions, 3 (0.9%) were elective pregnancy terminations, and 2 (0.6%) were stillbirths. In prospective live birth cases, there were 7/111 (6.3%) preterm births and 5/115 (4.3%) neonates with a low birth weight. The prevalence of total MCM among prospective cases was 1.7% (2 cases of 116 live births and fetal death/stillbirth), which is slightly lower than the background rates from MACDP (3%) and EUROCAT (2.1%). Conclusions This study did not indicate an increase in the rate of adverse pregnancy and fetal outcomes after paternal exposure to GA. These results provide additional information regarding pregnancy outcomes following paternal exposure to GA for healthcare professionals, male patients and their female partners who are considering pregnancy while their male partner is using GA.

Potential risk of gestational diabetes mellitus in females undergoing in vitro fertilization: a pilot study

BackgroundMost of the cases of hyperglycemia during pregnancy are attributed to gestational diabetes mellitus (GDM) (75–90%). Women diagnosed with GDM are at an increased risk for complications during pregnancy and delivery. This observational prospective study aimed to investigate the potential risk of GDM among Egyptian females following in vitro fertilization (IVF) pregnancies compared to spontaneous pregnancies (SC).MethodsThis prospective cohort study included normoglycemic females without any history of dysglycemia before this conception. Subjects were divided according to the type of conception into two age and BMI-matched groups: (IVF group): 55 pregnant females conceived by IVF, and (SC group) spontaneous pregnancy: 55 pregnant females conceived spontaneously. A one-step oral glucose tolerance test (OGTT) was performed at gestational weeks 20 and 28 for all study subjects.ResultsThe incidence of GDM was statistically significantly higher in the IVF group compared to the spontaneous pregnancy (SC) group (20 and 5.5%, respectively), p = 0.022 at week 28. On comparing the incidence of GDM on early screening at week 20 in both groups, the incidence of GDM in the IVF group was significantly higher (16.4%) compared to (3.6%) in the spontaneous pregnancy (SC) group, p = 0.026.ConclusionsIVF may have an increased potential risk for GDM. Moreover, the diagnosis of GDM may occur early (week 20), highlighting the need for precise and early screening for GDM in IVF pregnancies.

Predictive models of miscarriage on the basis of data from a preconception cohort study

To use self-reported preconception data to derive models that predict the risk of miscarriage. Prospective preconception cohort study. Not applicable. Study participants were female, aged 21-45 years, residents of the United States or Canada, and attempting spontaneous pregnancy at enrollment during 2013-2022. Participants were followed for up to 12 months of pregnancy attempts; those who conceived were followed through pregnancy and postpartum. We restricted analyses to participants who conceived during the study period. On baseline and follow-up questionnaires completed every 8 weeks until pregnancy, we collected self-reported data on sociodemographic factors, reproductive history, lifestyle, anthropometrics, diet, medical history, and male partner characteristics. We included 160 potential predictor variables in our models. The primary outcome was a miscarriage, defined as pregnancy loss before 20 weeks of gestation. We followed participants from their first positive pregnancy test until miscarriage or a censoring event (induced abortion, ectopic pregnancy, loss of follow-up, or 20 weeks of gestation), whichever occurred first. We fit both survival and static models using Cox proportional hazards models, logistic regression, support vector machines, gradient-boosted trees, and random forest algorithms. We evaluated model performance using the concordance index (survival models) and the weighted F1 score (static models). Among the 8,720 participants who conceived, 20.4% reported miscarriage. In multivariable models, the strongest predictors of miscarriage were female age, history of miscarriage, and male partner age. The weighted F1 score ranged from 73%-89% for static models and the concordance index ranged from 53%-56% for survival models, indicating better discrimination for the static models compared with the survival models (i.e., the ability of the model to discriminate between individuals with and without miscarriage). No appreciable differences were observed across strata of miscarriage history or among models restricted to ≥8 weeks of gestation. Our findings suggest that miscarriage is not easily predicted on the basis of preconception lifestyle characteristics and that advancing age and a history of miscarriage are the most important predictors of incident miscarriage.

Naissances vivantes après cancer du sein parmi les femmes désirant un enfant

Introduction: In France, the breast cancer is the most common cancer among women under the age of 40. From 38 to 70 % of women have not fulfilled their parental plans at the time of diagnosis. The gonadotoxicity of the treatments and the follicular physiological decline linked to age can become an obstacle to this project.Methods: 386 patients treated for breast cancer at the Centre Georges François Leclerc in Dijon between January 2011 and December 2018 were identified. 192 patients aged under 39 met the inclusion criteria. We excluded metastatic cancers, cancer in situ and pregnant patients at diagnosis. A total of 124 patients agreed to participate in the study. The included patients filled out a self-questionnaire. Data were collected from the patient’s electronic medical. The primary endpoint of this study was the live birth rate.Result: Among women who desired a child after breast cancer, the overall rate of live births was 36.2 % (21/58). Most achieved pregnancies were spontaneous (90.5 %). No factor was significantly associated with the absence of obtaining birth. Fertility was preserved by oocyte cryopreservation in 13.8 % of patients (17/124). The median time to conception in patients who received chemotherapy was 8 months [1.0-60.0] vs 2 months [1.0-7.0] in women who did not receive chemotherapy.Discussion: The non-negligible proportion of live births following spontaneous pregnancy after breast cancer allows us to be reassuring for patients. However, the emergence of new chemotherapy protocols whose consequences on long-term gonadotoxicity are still not well known requires further studies and prompts the promotion of fertility preservation as a precautionary measure.

The Impact of Latent Cytomegalovirus Infection on Spontaneous Abortion History and Pregnancy Outcomes in Romanian Pregnant Women.

Serum samples from 806 pregnant women (28.29 ± 4.50 years old) who came for a consultation at the Timisoara Clinical Emergency City Hospital between 2008 and 2010 were tested for anti-CMV IgM/IgG antibodies, and data about demography, obstetrical history, pregnancy complications, birth, and neonate were collected. The data were compared between the groups with and without latent CMV infection, and statistical significance was calculated. We did not find a difference regarding cesarean section (OR = 0.916, p = 0.856), placental abruption (OR = 1.004, p = 1.00), pregnancy-induced hypertension rate (OR = 1.078, p = 1.00), secondary sex ratio (0.882, p = 0.857), APGAR score (p = 0.225), gestational age at birth (p = 0.434), or birth weight (p = 0.365). A borderline significant difference was found regarding the presence of miscarriage history: OR = 8.467, p = 0.051. The presence of latent CMV infection does not affect the likelihood of complications in healthy women. A borderline significantly higher prevalence of miscarriage history was found in women with latent CMV infection.

Association of Serum Proteins Electrophoretic Pattern and Serum Hormones in Women with Spontaneous Pregnancy Loss.

Pregnancy is the state of carrying a developing embryo or fetus within a female body. Once pregnancy is established, a range of endocrinological events appear in its maintenance, finally helping in the successful pregnancy. The complications which are usually observed in pregnancy are gestational diabetes, preeclampsia, preterm labor, and spontaneous pregnancy loss or miscarriage, while 10%-15% of clinically recognized pregnancies terminate into spontaneous miscarriage. Thus, many attempts have been made by different researchers for the diagnosis of high-risk pregnancy on altered protein pattern using placental villous tissue or follicular fluid, but these are difficult to obtain and results of different studies are not constant. This study was designed to identify the association (if any) among serum protein(s) electrophoretic pattern and different serum hormones in normal pregnant women (controls) and gestational age-matched women with spontaneous pregnancy loss (cases). This study was carried out for 1½ year from October 2018 to March 2020 and included 120 participants (60 normal pregnant women and 60 women with spontaneous pregnancy loss) between 20 and 45 years of age with no mean age difference. The electrophoresis of serum was carried out using slab gel electrophoretic unit and serum thyroid-stimulating hormone (TSH), total tri-iodothyronine (TT3), total thyroxine (TT4), prolactin, and beta human chorionic gonadotropin (β-hCG) levels were analyzed using TSOSH AIA analyzer at Adesh University, Bathinda. Significant variations in the expression of proteins with molecular weight around ~150 kDa, ~50 kDa, and ~25 kDa were observed in normal pregnant women and women with spontaneous pregnancy loss. However, the protein band of ~50 kDa was found to be highly expressed in the serum of 1st and 2nd trimester women experiencing spontaneous pregnancy loss. Therefore, selected protein band of ~50 kDa was further processed by ECI-mass spectrophotometry QUAD time of flight and 365 different proteins were found, out of these; 34 proteins were found to be unidentified protein products (Verified using NCBI data base). Further, TT3, total proteins, β-hCG, and prolactin level were found to be low, whereas, TSH was found to be high in women experiencing spontaneous pregnancy loss. However, difference in the level of β-hCG in the 1st trimester and TT4 among normal pregnant women and women with spontaneous pregnancy loss was observed to be statistically insignificant. This study indicated that the evaluation of serum protein variations along with hormonal profile may provide valuable information about high-risk pregnancy. Moreover, the differential expression of proteins in women with spontaneous pregnancy loss can be further explored to develop potential biomarker for the early identification of high-risk pregnancy and appropriate preventive measure.

The late effects of haematopoietic stem cell transplants in paediatric patients: a 25 year review.

A rare, large single centre study covering all long-term health outcomes of paediatric allogeneic HSCT survivors, to provide comprehensive local data, and identify gaps and future directions for improved care. To document endocrine sequelae and other late effects of all HSCT recipients. Retrospective review. Royal Children's Hospital Melbourne. 384 children and adolescents received HSCT. 228 formed the study cohort; 212 were alive at commencement of data accrual. None. Incidence of endocrinopathies; fertility, growth, bone and metabolic status; subsequent malignant neoplasms (SMNs). Gonadotoxicity was more common in females (p<0.001). Total body irradiation (TBI) conditioning was more toxic than chemotherapy alone. All females receiving TBI or higher cyclophosphamide equivalent doses (CED) developed premature ovarian insufficiency (POI) . In males, impaired spermatogenesis +/- testicular endocrine dysfunction was associated with increasing testicular radiation exposure. Preservation of gonadal function was associated with younger age at HSCT. Of sexually active females, 22% reported spontaneous pregnancies. Short stature was common, with growth hormone axis disruption in 30% of these. Of patients exposed to thyroid radiation 51% developed nodules, 30% malignant. Metabolic disturbances included hypertension, dyslipidemias, with both excess and underweight reported. Fragility fractures occurred in 6%; avascular necrosis in 6%. 13% developed SMNs, risk continuing to rise throughout follow-up. We confirm gonadal dysfunction, multiple endocrine and metabolic abnormalities, thyroid cancer and SMNs, as common sequelae of HSCT, and identify gaps in management - particularly the need for informed fertility counselling and pretreatment fertility preservation, evaluation and management of bone health, and underline need for early lifestyle modification, long-term surveillance, and prospective planned studies aimed at reducing complication risk.

Obstetric and maternal outcomes of IVF and oocyte donation pregnancies among women ages 40–45—a large cohort study

PurposeTo analyze the perinatal and maternal outcomes of women ranging in age from 40 to 45 years who gave birth after in vitro fertilization or oocyte donation, compared to spontaneous conception.MethodsThis retrospective cohort study used electronic data from a national healthcare service from 2000 through 2019. Three groups were compared: spontaneous pregnancy (SC), in vitro fertilization (IVF) utilizing autologous oocytes, and pregnancies resulting from oocyte donation (OD). The primary study outcomes were preterm labor (PTL) before 37 weeks of gestation, and infants classified as small for gestational age (SGA).ResultsThe cohort included 26,379 SC, 2237 IVF pregnancies, and 300 OD pregnancies for women ages 40–45 years at delivery. Women with OD or IVF had a higher incidence of PTL < 37 weeks compared to women with SC (19.7% vs. 18% vs. 6.9%, p = 0.001), PTL < 34 (7% vs. 4.5% vs. 1.4%, p = 0.001), PTL < 32 (3.7 vs. 2.1 vs. 0.6, p = 0.001). A multivariable logistic regression for PTL < 37 weeks demonstrated that age (OR = 1.18) and hypertensive diseases (OR = 3.4) were statistically significant factors. The OD group had a lower rate of SGA compared to SC (1% vs. 4.3%, p = 0.001), while the IVF group had a higher rate of SGA compared to SC (9.1% vs. 4.3%, p = 0.001). Hypertensive diseases in pregnancy were significantly higher among the OD group and the IVF group compared to SP pregnancies (3.3% vs. 1%, p = 0.002; 2.3% vs. 1%, p = 0.001, respectively).ConclusionsWomen ages 40–45 undergoing IVF or OD have a greater risk of PTL, possibly due to higher rates of hypertensive disorders of pregnancy.

Analysis of Factors Affecting Fetal Fraction in Cell-Free DNA Test

Background: Noninvasive prenatal testing (NIPT) serves as a screening method to assess the risk of chromosomal abnormalities in the fetus, including trisomy 18, 21, and 13. The reliability and success of this test are influenced by the proportion of circulating cell-free DNA obtained from the feto-placental unit, known as the fetal fraction (FF). Objectives: Our study aims to investigate the fetal and maternal factors affecting FF. Methods: Our research involved 1 150 patients referred for NIPT due to various reasons such as maternal age over 35, high-risk screening tests in the first or second trimester, history of trisomy in previous pregnancies, or patient request. Patients completed a questionnaire providing variables including maternal and fetal age, body mass index (BMI), smoking status, multiple pregnancies, and medication use such as Heparin or enoxaparin. Noninvasive prenatal testing was conducted on blood samples using Ion proton technology by Premaitha of the UK. The results, including fetal sex, trisomy risk, fetal fraction, and abnormal sex chromosomes, were analyzed using IBM SPSS 27 to assess the relationship between FF percentage and other variables. Results: The study included 1150 NIPT cases, with maternal ages ranging from 13 to 48 years, BMI from 15 to 70, and gestational age from 10 to 27 weeks. Among these, 96.4% were singleton pregnancies and 3.6% were twin pregnancies. Spontaneous pregnancies accounted for 88.9%, while 9.2% were IVF and 1.2% were IUI. Fetal sex distribution was 45.9% female and 54.1% male. FF ranged from 4% to 20.7%, with a mean FF of 11.07. No significant correlation was found between maternal age, fetal age, maternal BMI, trisomies, and FF. Conclusions: We can see that maternal age has no significant correlation with the fetal fraction. Although fetal age increases, the fetal fraction does too, but this increase was not significant. Body mass index, the route of pregnancy, and the sex of the fetus had no effect on FF. Despite NIPS being safer and yielding better results, other factors can still influence the outcomes of NIPS. Therefore, this test remains a screening tool, and clinical counseling should be conducted both before and after the test.

Resumption of ovulation in anovulatory women with PCOS and obesity is associated with reduction of 11β-hydroxyandrostenedione concentrations.

Is resumption of ovulation after a 6-month lifestyle intervention in women with PCOS and obesity associated with differential changes in endocrine and metabolic parameters (weight, insulin resistance, anti-Müllerian hormone (AMH), and androgens) compared to women with PCOS who remained anovulatory? Resumption of ovulation after a 6-month lifestyle intervention in women with PCOS and obesity is associated with changes in serum 11β-hydroxyandrostenedione (11OHA4) concentrations. Lifestyle interventions have been shown to reduce clinical and biochemical hyperandrogenism in women with PCOS. Weight loss of 5-10% may reverse anovulatory status, thereby increasing natural conception rates. However, the mechanisms underlying why some women with PCOS remain anovulatory and others resume ovulation after weight loss are unclear. Reproductive characteristics at baseline and a greater degree of change in endocrine and metabolic features with lifestyle intervention may be crucial for ovulatory response. We used data and samples originating from an earlier randomized controlled trial (RCT), which examined the efficacy of a 6-month lifestyle intervention prior to infertility treatment compared to prompt infertility treatment on live birth rate in women with obesity. A total of 577 women with obesity (BMI > 29 kg/m2) were randomized between 2009 and 2012. Anovulatory women with PCOS who were allocated to the intervention arm of the original RCT (n = 95) were included in the current analysis. We defined women as having resumed ovulation (RO+) based on the following criteria: spontaneous pregnancy; or assignment to expectant management; or IUI in natural cycles as the treatment strategy after lifestyle intervention. Steroid hormones were measured using liquid chromatography tandem mass spectrometry. Generalized estimating equations with adjustment for baseline measures and interaction between group and time was used to examine differences in changes of endocrine and metabolic parameters between RO+ (n = 34) and persistently anovulatory women (RO-, n = 61) at 3 and 6 months after intervention. At baseline, the mean ± SD age was 27.5 ± 3.6 years in the RO+ group and 27.9 ± 4.1 years in the RO- group (P = 0.65), and the mean ± SD weights were 101.2 ± 9.5 kg and 105.0 ± 14.6 kg, respectively (P = 0.13). Baseline AMH concentrations showed significant differences between RO+ and RO- women (median and interquartile range [IQR] 4.7 [3.2; 8.3] versus 7.2 [5.3; 10.8] ng/ml, respectively). Baseline androgen concentrations did not differ between the two groups. During and after lifestyle intervention, both groups showed weight loss; changes in 11OHA4 were significantly different between the RO+ and RO groups (P-value for interaction = 0.03). There was a similar trend for SHBG (interaction P-value = 0.07), and DHEA-S (interaction P-value = 0.06), with the most pronounced differences observed in the first 3 months. Other parameters, such as AMH and FAI, decreased over time but with no difference between the groups. No high-resolution transvaginal ultrasonography was used to confirm ovulatory status at the end of the lifestyle program. The small sample size may limit the robustness of the results. Reduction of androgen concentrations during and after lifestyle intervention is associated with recovery of ovulatory cycles. If our results are confirmed in other studies, androgen concentrations could be monitored during lifestyle intervention to provide individualized recommendations on the timing of resumption of ovulation in anovulatory women with PCOS and obesity. The study was supported by a grant from ZonMw, the Dutch Organization for Health Research and Development (50-50110-96-518). The Department of Obstetrics and Gynecology of the UMCG received an unrestricted educational grant from Ferring Pharmaceuticals BV, The Netherlands.

Arsenic Methyltransferase and Apolipoprotein E Polymorphism in Pregnant Women Exposed to Inorganic Arsenic in Drinking Water in Western Romania.

Previous studies have shown that inorganic arsenic (iAs) exposure may be associated with genotoxic and cytotoxic effects. The aim of this study was to evaluate the relationship between several polymorphisms in AS3MT and APOE genes and urinary As and the relationship between these polymorphisms and pregnancy loss. We determined urinary As concentrations and performed genotyping analysis in 50 cases of spontaneous pregnancy loss and 50 controls, matched to cases on gestational age. The most frequently identified AS3MT polymorphisms in both cases and controls were in rs10748835 (80% cases and 68% controls), rs3740400 (78% cases and 64% controls), rs7085104 (74% cases and 48% controls), and rs1046778 (62% cases and 54% controls). We identified 30 different haplotypes in AS3MT SNPs, with four predominant haplotypes (>8%). Cases with Haplotype 1 had four-fold higher urinary DMA and two-fold higher MMA concentration than those without this haplotype, the MMA levels were lower in cases and controls with Haplotype 4 compared to Haplotype 1, and the DMA levels were significantly lower in cases with Haplotype 4 compared to Haplotype 3. Cases with Haplotype 1 had higher levels of all analyzed biomarkers, suggesting that Haplotype 1 may be associated with greater exposure to iAs and tobacco smoke. Our results suggest the importance of the AS3MT gene in iAs metabolism among pregnant women with low-level drinking water iAs exposure.

Medical treatment for early pregnancy loss following in vitro fertilization compared to spontaneous pregnancies.

Misoprostol is a well-studied medical treatment for early pregnancy loss (EPL), with success rates ranging between 70 and 90%. However, treatment failure is associated with major patient discomfort, including the need for surgical intervention to evacuate the uterus. It was previously reported that medical treatment was especially successful among women who conceived after in vitro fertilization (IVF). We aimed to study if there is a difference in rates of medical treatment failures for EPL between pregnancies conceived by IVF and spontaneous pregnancies. In this retrospective cohort study, we included all women who underwent medical treatment for EPL at our institute between 07/2015 and 12/2020. Treatment outcome was compared between IVF and spontaneous pregnancies. Treatment failure was defined as a need for surgical intervention, namely, dilation & curettage (D&C) and/or hysteroscopy, due to retained products of conception, which was defined as a gestational sac or endometrial thickness greater than 15 mm in a TVS scan. Overall, 775 patients were included, of which 195 (169/775 = 25.1%) ultimately required surgical intervention. There was no difference between the study groups in the rate of treatment failure. However, among IVF pregnancies, the rate of emergency D&C was lower (3.6% vs. 9.8%, p = 0.001), compared to spontaneous group. In cases of medical treatment for EPL, IVF pregnancies had no differences in rates of treatment failure compared to spontaneous pregnancies. That being said, IVF pregnancies have lower chances to undergo emergency D&C, compared to spontaneous pregnancies.

Assisted reproductive technologies could be associated with higher risk of parenting difficulties in women with postpartum major depression.

No increased risk of postpartum major depression (PPMD) was reported in women conceiving through assisted reproductive technologies (ART). However, ART may be associated with a higher risk of parenting difficulties in women with PPMD. In 359 women with a PPMD admitted to a Mother-Baby Unit (MBU), ART-women (4.2%) showed a 5-fold higher rate of parenting difficulties than those with spontaneous pregnancy (73.33% vs. 35.17%, multivariate ORa = 5.09 [1.48-17.48] p = 0.01). Specific support for mother-child relationship should be implemented in ART-women with PPMD.

Fertility and sexual activity in patients with Triple A syndrome.

Triple A syndrome, caused by autosomal recessively inherited mutations in the AAAS gene is characterized by alacrima, achalasia, adrenal insufficiency, and neurological impairment. To the best of our knowledge, no patients of both sexes have been reported to have offspring. Our aim was to assess the causes of infertility in male patients with this multisystemic syndrome, and to present a female patient that spontaneously conceived a child. Cross-sectional study. Six males aged 19-48 years were included. Gonadotropins, testosterone, DHEAS, androstenedione, inhibin B, anti-Mullerian hormone measurements and testicular ultrasound were performed. All six male patients had impaired general health and neurological symptoms including erectile and ejaculatory dysfunction. None of them had an offspring. The only demonstrated cause of infertility in our male patients was erectile and ejaculatory dysfunction which precludes sexual intercourse. Our patients had normal libido but were sexually abstinent. Except for low adrenal androgen levels, the concentrations of all measured hormones as well as testicular ultrasound were normal which may indicate the possibility of spermatogenesis in male patients with triple A syndrome. Little is known about fertility in female patients, but based on our observations spontaneous pregnancies seem to be possible. Our results contribute to still scarce knowledge on fertility in patients with Triple A syndrome and as well represents a foundation for further research on causes of infertility and possible treatment options.

HLA-G isoforms, HLA-C allotype and their expressions differ between early abortus and placenta in relation to spontaneous abortions

IntroductionSpontaneous abortion (SAB) affects approximately 10% of clinically recognized pregnancies. Fetal trophobalst invasion and remodeling of maternal spiral arteries is reported to be dependent on crosstalk between HLA-C/HLA-G expressed on extra villous trophoblast (EVTs)and Killer cell Immunoglobin like receptors (KIRs) of decidual NK (dNK). Immune dysfunction in decidua contributes to early miscarriage. MethodologyThe study used mother neonate paired cord blood and term placenta samples (n = 46), elective abortus (n = 17,gestational age = 10–12 weeks of pregnancy) and SAB abortus (n = 24, gestational age = 12–15 weeks of pregnancy) for HLA-G, KIR2D and HLA-C. In addition, term placenta was collected from women with history of spontaneous pregnancy loss (n = 24) and women with history of live birth (n = 32). SSP-PCR was used for genotyping, RT-PCR for gene expression, copy number variation (CNVs) and HLA-C allotyping and ELISA for protein expression studies. ResultsMembrane bound HLA-G4 isoform proportion was higher 39.28%, p = 0.02) in term placenta. SAB abortus had higher proportion of HLA-G3 (50%),while elective abortus exhibited higher proportion of soluble isoforms (HLA-G5, = 5.9, HLA-G6 = 5.9%, HLA-G7 = 11.8%).Higher inhibitory KIR2DL1 content and copy numbers with lower HLA-C2 in SAB contrasted with higher copy numbers of KIR2DS1(p = 0.001), KIR2DS1+/2DL1+- HLA-C2 combined genotype in healthy placenta. Elevated KIR2D protein levels (p = 0.001), and concurrently, HLA-C levels were upregulated in healthy placenta. ConclusionOur data supports lower cognate receptor ligand KIR2DS1+/2DL1+ HLA–C2 together with predominance of HLA-G3 isoform in SAB as confounding factors in spontaneous pregnancy loss. HLA-G isoforms and expression differed between first trimester abortus and term placenta suggesting temporal modulation and marks novelty of the study.

Pregnancies and births in women with previous abdominal myomectomy

Background: Uterine leiomyoma may cause pelvic symptoms and may also interfere with the reproductive desires of many women. Consequently, some women may undergo myomectomy as a fertility sparring method to relieve symptoms or as a method to improve their fertility. Objective: We aimed to assess pregnancies and deliveries in women with previously myomectomy both in spontaneous pregnancies and with use of assisting reproductive techniques. Also, we aimed to asses if the reproductive prognosis differed between different surgical approaches. Study design: In this historical cohort study we collected data regarding myomectomies, pregnancies, use of assisting reproductive techniques and births from national health registries. All Danish women were followed from 1996 through 2017. Results: Of 5.281 women undergoing myomectomy, 97% had one and 3% had two or more myomectomies. Median age at first surgery was 38.5 years (interquartile range 34.1-44.6 years). Of 5.430 myomectomies conducted, 71% were done by laparotomy and 29% by laparoscopy. Of the 5.281 women treated with myomectomy, 1.586 (30%) became pregnant and 1.145 (22%) gave birth. In the entire cohort of 5.281 women, 1.056 (20%) were treated with assisting reproductive techniques. Of these 1.056 women, 659 (62%) got pregnant and 461 (44%) delivered. Median time from surgery to pregnancy was 1.2 years. Significantly more women became pregnant and gave birth when treated with laparotomy as compared to laparoscopy. However, the effect was only significant for women younger than 30 years or older than 40 years at first surgery. Conclusion: As the proportion of women attempting pregnancy was unknown, the overall figure of 30% pregnancy rate is a minimum estimate of the real chance of achieving pregnancy after myomectomy.

Effect of endometrial injury on pregnancy outcomes in infertile women undergoing intrauterine insemination.

One of the most common treatments for infertility is intrauterine insemination (II). The objective of this study was to determine the effect of endometrial injury on pregnancy outcomes in unexplained infertility in women undergoing II. In this randomized clinical trial, 122 women with unexplained infertility who were referred to Shariati Hospital from 2018 to 2020 were enrolled. They underwent ovulation induction using letrozole and gonadotropins. On day 9 of stimulation, they were randomly assigned to two similar groups of the same size. The first group underwent endometrial local injury by pipelle endometrial sampling, and the second group (control group) received no intervention. Only 1 II cycle was performed for each patient. Patients with negative pregnancy outcomes were followed up for 3 months. Endometrial thickness, dominant follicle count, chemical and clinical pregnancy rate, miscarriage rate, and spontaneous pregnancy rate after the II cycle were compared between the two groups. Endometrial thickness, dominant follicle count, chemical and clinical pregnancy rate, and miscarriage rate in the same II cycle were not different between the two groups (p>0.05). However, the spontaneous pregnancy rate after the II cycle was significantly higher in the endometrial injury group (p=0.02). Endometrial injury increases pregnancy rates in later cycles but not in the same II cycle.

Spontaneous heterotopic pregnancy resulting in tubal rupture and complete spontaneous abortion: a case report in Tiko, Cameroon

Introduction and importance: A heterotopic pregnancy (HP) following spontaneous conception is a rare and potentially life-threatening condition. Its diagnosis can be overlooked, hence remaining one of the challenging gyneco-obstetrical emergencies, especially in the low-resource setting. Case presentation: A 24-year-old G2P0010 at 11 weeks of gestation with a history of one induced abortion and a family history of twin pregnancies presented with an acute abdomen, associated with vaginal spotting in an afebrile context. An abdominopelvic ultrasound showed retained products of conception, and the presence of a left adnexal mass suggestive of an extrauterine gestational sac at ~6 weeks of gestation. There was spontaneous expulsion of retained products of conception. The deterioration of the hemodynamic stability of the patient prompted an emergency laparotomy to be done. The patient was transfused, postsalpingectomy counseling done and was discharged on oral analgesics, blood tonics, and antibiotics on day 6 postoperation. Clinical discussion: HP following spontaneous conception is a rare and potentially life-threatening condition. This case reports on the management of spontaneous HP resulting in a ruptured ectopic pregnancy (EP) and a complete spontaneous abortion managed in a low-resource setting. This case emphasizes the importance of a systematic ultrasound to be done for all patients with a clinically confirmed abortion to rule out an associated EP. Conclusion: A spontaneous abortion without signs of peritoneal irritation can be associated with an EP. Ultrasound can help in the early diagnosis, and laparotomy can be life-saving.
