Bariatric surgery for spontaneous ovulation in women living with polycystic ovary syndrome: the BAMBINI multicentre, open-label, randomised controlled trial.

BACKGROUND: Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility. Obesity exacerbates the reproductive complications of PCOS; however, the management of obesity in women with PCOS remains a large unmet clinical need. Observational studies have indicated that bariatric surgery could improve the rates of ovulatory cycles and prospects of fertility; however, the efficacy of surgery on ovulation rates has not yet been compared with behavioural modifications and medical therapy in a randomised trial. The aim of this study was to compare the safety and efficacy of bariatric surgery versus medical care on ovulation rates in women with PCOS, obesity, and oligomenorrhoea or amenorrhoea. METHODS: In this multicentre, open-label, randomised controlled trial, 80 women older than 18 years, with a diagnosis of PCOS based on the 2018 international evidence-based guidelines for assessing and managing PCOS, and a BMI of 35 kg/m2 or higher, were recruited from two specialist obesity management centres and via social media. Participants were randomly assigned at a 1:1 ratio to either vertical sleeve gastrectomy or behavioural interventions and medical therapy using a computer-generated random sequence (PLAN procedure in SAS) by an independent researcher not involved with any other aspect of the clinical trial. The median age of the entire cohort was 31 years and 79% of participants were White. The primary outcome was the number of biochemically confirmed ovulatory events over 52 weeks, and was assessed using weekly serum progesterone measurements. The primary endpoint included the intention-to-treat population and safety analyses were per-protocol population. This study is registered with the ISRCTN registry (ISRCTN16668711). FINDINGS: Participants were recruited from Feb 20, 2020 to Feb 1, 2021. 40 participants were assigned to each group and there were seven dropouts in the medical group and ten dropouts in the surgical group. The median number of ovulations was 6 (IQR 3·5-10·0) in the surgical group and 2 (0·0-4·0) in the medical group. Women in the surgical group had 2.5 times more spontaneous ovulations compared with the medical group (incidence rate ratio 2·5 [95% CI 1·5-4·2], p<0·0007). There were more complications in the surgical group than the medical group, although without long-term sequelae. There were 24 (66·7%) adverse events in the surgical group and 12 (30·0%) in the medical group. There were no treatment-related deaths. INTERPRETATION: Bariatric surgery was more effective than medical care for the induction of spontaneous ovulation in women with PCOS, obesity, and oligomenorrhoea or amenorrhoea. Bariatric surgery could, therefore, enhance the prospects of spontaneous fertility in this group of women. FUNDING: The Jon Moulton Charity Trust.

Functional hypothalamic amenorrhea: gut microbiota composition and the effects of exogenous estrogen administration.

Functional hypothalamic amenorrhea (FHA) is characterized by estrogen deficiency that significantly impacts metabolic, bone, cardiovascular, mental, and reproductive health. Given the importance of environmental factors such as stress and body composition, and particularly considering the importance of estrogens in regulating the gut microbiota, some changes in the intestinal microenvironment are expected when all of these factors occur simultaneously. We aimed to assess whether the gut microbiota composition is altered in FHA and to determine the potential impact of hormonal replacement therapy (HRT) on the gut microbiota. This prospective observational study included 33 patients aged 18-34 yr with FHA and 10 age-matched healthy control women. Clinical, hormonal, and metabolic evaluations were performed at baseline for the FHA group only, whereas gut microbiota profile was assessed by 16S rRNA gene amplicon sequencing for both groups. All measurements were repeated in patients with FHA after receiving HRT for 6 mo. Gut microbiota alpha diversity at baseline was significantly different between patients with FHA and healthy controls (P < 0.01). At the phylum level, the relative abundance of Fusobacteria was higher in patients with FHA after HRT (P < 0.01), as was that of Ruminococcus and Eubacterium at the genus level (P < 0.05), which correlated with a decrease in circulating proinflammatory cytokines. FHA is a multidimensional disorder that is interconnected with dysbiosis through various mechanisms, particularly involving the gut-brain axis. HRT appears to induce a favorable shift in the gut microbiota in patients with FHA, which is also associated with a reduction in the systemic inflammatory status.NEW & NOTEWORTHY Our study marks the first comprehensive analysis of gut microbiota composition in FHA and the impact of HRT on it, along with biochemical, anthropometric, and psychometric aspects. Our results indicate distinct gut microbiota composition in patients with FHA compared with healthy individuals. Importantly, HRT prompts a transition toward a more beneficial gut microbiota profile and reduced inflammation. This study validates the concept of FHA as a multifaceted disorder interlinked with dysbiosis, particularly involving the gut-brain axis.

Characteristics of bone mineral density in patients with functional hypothalamic amenorrhoea and its association with reproductive hormones and body composition.

OBJECTIVE: Bone mineral density (BMD) is typically reduced in patients with female athlete triad (FAT) and anorexia nervosa (AN). However, bone health in most patients with functional hypothalamic amenorrhoea (FHA), who may not suffer from severe energy deficiency, has not received adequate attention in clinical practice. This study aimed to investigate BMD and its association with clinical and endocrine features in individuals with FHA and to provide clinical evidence for improving bone loss and preventing osteoporosis in FHA. DESIGN: To assess the bone status of patients with FHA and investigate its association with various clinical and endocrinological characteristics. PATIENTS: We retrospectively analysed 80 patients with FHA who attended the Obstetrics and Gynecology Hospital of Fudan University from January 2022 to March 2023. MEASUREMENTS: The levels of reproductive hormones, including luteinising hormone (LH), follicle-stimulating hormone, oestradiol (E2 ) and total testosterone (TT), were examined at the time of initial diagnosis, and a body composition analyser was used to measure body fat percentage (BF%), lean body mass (LBM) and segmental muscle/fat. Dual-emission X-ray absorptiometry was used to measure lumbar spine BMD and femoral neck BMD in patients with FHA, and the Z score was calculated. RESULTS: The study cohort consisted of 80 female patients with FHA. The average age of the patients was 24.64 ± 6.02 years, and their body mass index (BMI) was 19.47 ± 2.86 kg/m2 . The duration of weight loss was 12 (6, 24) months, while the duration of oligo/amenorrhoea was 12 (4.5, 24) months. The mean degree of weight loss was 18.39 ± 9.53%. Low BMD were present in 15% of patients with FHA at the lumbar spine and/or femoral neck; 12.5% and 10% had low bone mass at the lumbar spine and femoral neck, respectively. The low bone mass group experienced a longer period of weight loss than the normal group [24 (16.5, 60) vs. 12 (4.5, 24) months, p = .037]. In addition, the abnormal group had a lower BMR (basal metabolic rate, BMR) [1158 ± 85 vs. 1231 ± 91 kcal/day, p = .011] and lower bone mineral content [2.15 ± 0.26 vs. 2.43 ± 0.31 kg, p = .009] than the normal group. Both LBMD and femoral neck BMD (Fn BMD) were positively correlated with BMI, BF%, LBM, and regional muscle/fat mass (all p < .05). There was also a positive correlation between LBMD and basal LH levels (p = .009) and waist-to-hip ratio (p = .034), whereas Fn BMD was positively correlated with TT levels (p = .029). Multiple linear regression analysis showed that LBM was positively associated with LBMD (ß = .007, 95% confidence interval [CI] = 0.004-0.009, p < .001), while trunk muscle mass was positively associated with Fn BMD (ß = .046, 95% CI = 0.013-0.080, p = .008). CONCLUSION: Fifteen percent of the patients with FHA exhibited low bone mass, a condition associated with prolonged weight loss. The basal LH and TT levels showed positive correlations with LBMD and Fn BMD, respectively. Meanwhile, BMR levels, BMI, BF%, and muscle mass were all positively correlated with LBMD and Fn BMD. Clinically, we should be attentive to suboptimal bone health in patients with FHA and take early screening, diagnosis and intervention measures, especially appropriate muscle mass gain, to prevent the onset of osteoporosis and fragility fractures in the long term.

Proposal for targeted, neo-evolutionary-oriented, secondary prevention of early-onset endometriosis and adenomyosis. Part I: pathogenic aspects.

The potential for repeated ovulation and menstruation is thought to have provided a Darwinian advantage during the Palaeolithic. Reproductive conditions remained relatively stable until the pre-industrial era, characterized by late menarche, very young age at first birth, multiple pregnancies, and prolonged periods of lactational amenorrhoea. For hundreds of thousands of years, menstruators experienced few ovulatory cycles, even though they were genetically adapted to ovulate and menstruate every month. In the post-industrial era, the age at menarche gradually declined, the age at first birth progressively increased, and breastfeeding became optional and often of short duration. This created a mismatch between genetic adaptation and socio-environmental evolution, so that what was initially a probable reproductive advantage subsequently contributed to increased susceptibility to diseases associated with lifetime oestrogen exposure, such as ovarian, endometrial and breast cancer and, hypothetically, also those associated with the number of ovulatory menstruations, such as endometriosis and adenomyosis. The incidence of endometriosis shows a steep and progressive increase around the age of 25 years, but given the consistently reported delay in diagnosis, the actual incidence curve should be shifted to the left, supporting the possibility that the disease has its roots in adolescence. This raises the question of whether, from an evolutionary point of view, anovulation and amenorrhoea should not still be considered the physiological state, especially in the postmenarchal period. However, an increase in the frequency of endometriosis in recent decades has not been demonstrated, although this deserves further epidemiological investigation. In addition, as endometriosis occurs in a minority of individuals exposed to retrograde menstruation, other important pathogenic factors should be scrutinised. Research should be resumed to explore in more detail the transtubal reflux of not only blood, but also endometrial cells, and whether they are systematically present in the peritoneal fluid after menstruation. If repetitive ovulatory menstruation during the early reproductive years is shown to increase the risk of endometriosis and adenomyosis development and progression in susceptible individuals, hormonal interventions could be used as secondary prevention in symptomatic adolescents.

FMR1 allelic complexity in premutation carriers provides no evidence for a correlation with age at amenorrhea.

BACKGROUND: Premutations in the Fragile X Messenger Ribonucleoprotein 1 (FMR1) gene, defined as between 55 and 200 CGGs, have been implicated in fragile X-associated primary ovarian insufficiency (FXPOI). Only 20% of female premutation carriers develop early ovulatory dysfunction, the reason for this incomplete penetrance is unknown. This study validated the mathematical model in premutation alleles, after assigning each allele a score representing allelic complexity. Subsequently, allelic scores were used to investigate the impact of allele complexity on age at amenorrhea for 58 premutation cases (116 alleles) previously published. METHODS: The allelic score was determined using a formula previously described by our group. The impact of each allelic score on age at amenorrhea was analyzed using Pearson's test and a contour plot generated to visualize the effect. RESULTS: Correlation of allelic score revealed two distinct complexity behaviors in premutation alleles. No significant correlation was observed between the allelic score of premutation alleles and age at amenorrhea. The same lack of significant correlation was observed regarding normal-sized alleles, despite a nearly significant trend. CONCLUSIONS: Our results suggest that the use of allelic scores combination have the potential to explain female infertility, namely the development of FXPOI, or ovarian dysfunction, despite the lack of correlation with age at amenorrhea. Such a finding is of great clinical significance for early identification of females at risk of ovulatory dysfunction, enhancement of fertility preservation techniques, and increasing the probability for a successful pregnancy in females with premutations. Additional investigation is necessary to validate this hypothesis.

Primary amenorrhea in myotonic dystrophy type 1: Initial presentation versus incidental finding on whole genome sequencing.

Myotonic dystrophy type 1 is an autosomal dominant condition due to a CTG repeat expansion in the myotonic dystrophy protein kinase (DMPK) gene. This multisystem disorder affects multiple organ systems. Hypogonadism in males affected by myotonic dystrophy is commonly reported; however, the effect on female hypogonadism remains controversial. A 19-year-old female was referred to our genetics clinic due to primary amenorrhea without any family history of similar symptoms. Initial genetics evaluation identified a variant of uncertain significance in IGSF10, c.2210T>C (p.Phe737Ser). Follow-up genetic evaluation via whole genome sequencing identified at least 100 CTG repeats in the DMPK gene, thus resulting in the diagnosis of myotonic dystrophy type 1. The patient remains otherwise asymptomatic from myotonic dystrophy. This is the first report that demonstrates primary amenorrhea as a possible presenting feature of myotonic dystrophy type 1, thus providing evidence supporting female hypogonadism in myotonic dystrophy type 1.

Relugolix combination therapy in Black/African American women with symptomatic uterine fibroids: LIBERTY Long-Term Extension study.

BACKGROUND: In the LIBERTY Long-Term Extension study, once-daily relugolix combination therapy (40 mg relugolix, estradiol 1 mg, norethindrone acetate 0.5 mg) substantially improved uterine fibroid-associated heavy menstrual bleeding throughout the 52-week treatment period in the overall study population. OBJECTIVE: Black or African American women typically experience a greater extent of disease and symptom burden of uterine fibroids vs other racial groups and have traditionally been underrepresented in clinical trials. This secondary analysis aimed to assess the efficacy and safety of relugolix combination therapy in the subgroup population of Black or African American women with uterine fibroids in the LIBERTY Long-Term Extension study. STUDY DESIGN: Black or African American premenopausal women (aged 18-50 years) with uterine fibroids and heavy menstrual bleeding who completed the 24-week randomized, placebo-controlled, double-blind LIBERTY 1 (identifier: NCT03049735) or LIBERTY 2 (identifier: NCT03103087) trials were eligible to enroll in the 28-week LIBERTY Long-Term Extension study (identifier: NCT03412890), in which all women received once-daily, open-label relugolix combination therapy. The primary endpoint of this subanalysis was the proportion of Black or African American treatment responders: women who achieved a menstrual blood loss volume of <80 mL and at least a 50% reduction in menstrual blood loss volume from the pivotal study baseline to the last 35 days of treatment by pivotal study randomized treatment group. The secondary outcomes included rates of amenorrhea and changes in symptom burden and quality of life. RESULTS: Overall, 241 of 477 women (50.5%) enrolled in the LIBERTY Long-Term Extension study self-identified as Black or African American. In Black or African American women receiving continuous relugolix combination therapy for up to 52 weeks, 58 of 70 women (82.9%; 95% confidence interval, 72.0%-90.8%) met the treatment responder criteria for reduction in heavy menstrual bleeding (primary endpoint). A substantial reduction in menstrual blood loss volume from the pivotal study baseline to week 52 was demonstrated (least squares mean percentage change: 85.0%); 64.3% of women achieved amenorrhea; 59.1% of women with anemia at the pivotal study baseline achieved a substantial improvement (>2 g/dL) in hemoglobin levels; and decreased symptom severity and distress because of uterine fibroid-associated symptoms and improvements in health-related quality of life through 52 weeks were demonstrated. The most frequently reported adverse events during the cumulative 52-week treatment period were hot flush (12.9%), headache (5.7%), and hypertension (5.7%). Bone mineral density was preserved through 52 weeks. CONCLUSION: Once-daily relugolix combination therapy improved uterine fibroid-associated heavy menstrual bleeding in most Black or African American women who participated in the LIBERTY Long-Term Extension study. The safety and efficacy profile of relugolix combination therapy in Black or African American women was consistent with previously published results from the overall study population through 52 weeks. Findings from this subanalysis will assist shared decision-making by helping providers and Black or African American women understand the efficacy and safety of relugolix combination therapy as a pharmacologic option for the management of uterine fibroid-associated symptoms.

Deficits in volumetric bone mineral density, bone microarchitecture, and estimated bone strength in women with atypical anorexia nervosa compared to healthy controls.

OBJECTIVE: Anorexia nervosa is associated with low bone mineral density (BMD) and deficits in bone microarchitecture and strength. Low BMD is common in atypical anorexia nervosa, in which criteria for anorexia nervosa are met except for low weight. We investigated whether women with atypical anorexia nervosa have deficits in bone microarchitecture and estimated strength at the peripheral skeleton. METHOD: Measures of BMD and microarchitecture were obtained in 28 women with atypical anorexia nervosa and 27 controls, aged 21-46 years. RESULTS: Mean tibial volumetric BMD, cortical thickness, and failure load were lower, and radial trabecular number and separation impaired, in atypical anorexia nervosa versus controls (p < .05). Adjusting for weight, deficits in tibial cortical bone variables persisted (p < .05). Women with atypical anorexia nervosa and amenorrhea had lower volumetric BMD and deficits in microarchitecture and failure load versus those with eumenorrhea and controls. Those with a history of overweight/obesity or fracture had deficits in bone microarchitecture versus controls. Tibial deficits were particularly marked. Less lean mass and longer disease duration were associated with deficits in high-resolution peripheral quantitative computed tomography (HR-pQCT) variables in atypical anorexia nervosa. DISCUSSION: Women with atypical anorexia nervosa have lower volumetric BMD and deficits in bone microarchitecture and strength at the peripheral skeleton versus controls, independent of weight, and particularly at the tibia. Women with atypical anorexia nervosa and amenorrhea, less lean mass, longer disease duration, history of overweight/obesity, or fracture history may be at higher risk. This is salient as deficits in HR-pQCT variables are associated with increased fracture risk. PUBLIC SIGNIFICANCE: Atypical anorexia nervosa is a psychiatric disorder in which psychological criteria for anorexia nervosa are met despite weight being in the normal range. We demonstrate that despite weight in the normal range, women with atypical anorexia nervosa have impaired bone density, structure, and strength compared to healthy controls. Whether this translates to an increased risk of incident fracture in this population requires further investigation.

Prevalence and risk factors associated with low bone mineral density in Asian adolescents with anorexia nervosa and atypical anorexia nervosa.

OBJECTIVE: This retrospective study aimed to evaluate the prevalence and risk factors for low bone mineral density (BMD) at diagnosis in Asian adolescent females with anorexia nervosa (AN) and atypical AN. METHOD: We analyzed the BMD results for 213 patients between 10 and 18 years of age, with AN and atypical AN receiving care at a pediatric hospital in Singapore. We used linear regression analyses to determine if type of eating disorder, premorbid weight, and duration of amenorrhea were risk factors for low BMD. For a subset of patients with repeat BMD evaluation, we used paired t-tests to assess the impact of weight or menstrual restoration on the change in BMD. RESULTS: The prevalence of BMD height-for-age Z-scores <-2 at presentation was higher in patients with AN (13.0%) than atypical AN (2.3%) (p = .034). In multivariate regression, a diagnosis of atypical AN was protective against low BMD at the lumbar spine (B = 0.394, p = .009) and total body less head (B = 0.774, p = .010). Duration of amenorrhea was not associated with BMD across all sites. For those with repeat BMD measures, there was significantly less deterioration in the BMD Z-scores for patients with weight or menstrual restoration (R = -0.22 ± 0.59, NR = -0.69 ± 0.43, p = .029). CONCLUSIONS: Duration of amenorrhea was not associated with BMD in this sample. A diagnosis of AN was correlated with lower BMD than atypical AN. Further research is needed to better understand the relationship between amenorrhea, weight status, and bone health in Asian adolescents with eating disorders. PUBLIC SIGNIFICANCE: In this sample, 13% of Asian adolescents with AN and 2.3% of Asian adolescents with atypical AN have low BMD. In our study population, duration of amenorrhea was not correlated with BMD. Among adolescents with AN, a history of being underweight at the highest pre-morbid BMI, is correlated with low BMD. It is important for physicians to take a thorough weight history in evaluating bone health in this population.

Associations between low body weight, weight loss, and medical instability in adults with eating disorders.

OBJECTIVE: The physical complications of atypical anorexia nervosa remain understudied, with most studies completed in adolescents. This study seeks to examine the impact of various weight measures as predictors of medical instability in a large cohort of adult eating disorder patients. METHODS: In this retrospective cohort study, the impact of admission body mass index (BMI), weight suppression, and recent weight loss (the rate of weight loss within the last 12 months) toward the development of medical complications of malnutrition were examined. Multivariable logistic regression assessed the association of binary clinical outcomes of interest with recent weight loss and weight suppression (adjusting for age, admission BMI, gender, and purging behaviors). Odds ratios (OR) and 99% confidence intervals were reported. RESULTS: Greater recent weight loss increased the odds of developing low prealbumin and reduced hand grip strength. A greater weight suppression was associated with increased likelihood of amenorrhea, reduced systolic blood pressure, nadir hemoglobin, and weekly weight gain upon nutritional rehabilitation. Lower admission BMI was predictive of all the medical outcomes examined, with the exception of bradycardia, and was generally the strongest predictor based on standardized coefficients. DISCUSSION: Recent weight loss and weight suppression are predictive of some of the physiologic changes of malnutrition, although low BMI is seemingly the greatest predictor for the development of these complications. These findings suggest that some patients with aggressive weight suppression and/or acute weight loss would benefit from medical stabilization, although this needs to be further defined. PUBLIC SIGNIFICANCE: In adults, low BMI seems to be a better predictor of medical complications than weight suppression or aggressive recent weight loss. In adults, greater weight suppression is associated with increased likelihood of amenorrhea, reduced systolic blood pressure, nadir hemoglobin, and weight gain upon nutritional rehabilitation.

Cardiac involvement and its clinical significance in patients with anorexia nervosa.

Cardiac complications are a major concern in patients with anorexia nervosa (AN) which contribute to morbidity and mortality. However, limited information exists regarding risk factors for the development of these complications. Our objective was to investigate the prevalence and associated risk factors of cardiac involvement among children and adolescents with AN admitted to a tertiary pediatric hospital. We collected demographic, clinical, and laboratory data from individuals with AN hospitalized between 2011 and 2020 in Schneider Children's Medical Center in Israel. Diagnosis was based on established criteria (DSM-5). Patients with other co-morbidities were excluded. Cardiac investigations included electrocardiograms (ECG) and echocardiograms. We conducted correlation tests between cardiac findings and clinical and laboratory indicators. A total of 403 AN patients (81.4% were females) with a median age of 15 ± 2 years were included in the study. Sinus bradycardia was the most common abnormality, observed in 155 (38%) participants. Echocardiogram was performed in 170 (42.2%) patients, of whom 37 (22%) demonstrated mild cardiac aberrations. Among those aberrations, 94.6% could be attributed to the current metabolic state, including pericardial effusion (15.3%) and valve dysfunction (8.8%). Systolic or diastolic cardiac dysfunction, tachyarrhythmias, or conduction disorders were not observed. Patients with new echocardiographic aberration had significantly lower body mass index (BMI) at admission, and the prevalence of amenorrhea and hypotension was higher in this group. CONCLUSIONS: The prevalence of cardiac involvement, except for sinus bradycardia, was notably low in our cohort. The presence of cardiac aberrations is correlated with several clinical variables: lower body mass index (BMI) and the presence of amenorrhea and hypotension at admission. Patients presenting with these variables may be at high risk for cardiac findings per echocardiography. Dividing the patients into high and low risk groups may enable targeted evaluation, while avoiding unnecessary cardiac investigations in low-risk patients. WHAT IS KNOWN: • Cardiac involvement in anorexia nervosa (AN) patients is a major concern, which contributes to morbidity and mortality. • It is unknown which patients are prone to develop this complication. WHAT IS NEW: • Cardiac complications in our cohort are less frequent compared to previous studies, and it is correlated with lower body mass index (BMI) at admission, and the prevalence of amenorrhea and hypotension.

Body weight variation is not an independent factor in the determination of functional hypothalamic amenorrhea in anorexia nervosa.

OBJECTIVE: Functional hypothalamic amenorrhea (FHA) is one of the foremost manifestations in anorexia nervosa (AN), but a subset of patients have menses despite marked weight loss and underweight. The aim of our study was to investigate parameters potentially influencing FHA in AN. DESIGN AND METHODS: In this observational retrospective study, we selected 114 female patients with AN who completed a 12 months semi-residential rehabilitation program and a subsequent 12 months outpatient follow-up. We divided our sample into three groups: "Group 0" patients who experienced FHA and recovered their menses, "Group 1" persistent FHA, "Group 2" never experienced FHA, and looked for clinical and hormonal correlations. RESULTS: At the enrollment, the BMI was higher in Group 2 than in Group 1 (p = 0.0202), but the last follow-up weight was higher in Group 1 (p < 0.0001) despite persistent amenorrhea. At logistic regression, the higher BMI at which patients experienced amenorrhea was the main prediction factor for persistent FHA. Notwithstanding comparable leptin levels at admission, they improved significantly at discharge only in Groups 0 and 2 (p = 0.0054 and p = 0.0104, respectively). FT3 at admission was significantly higher in Group 2 than in Group 0 (p = 0.0249). CONCLUSIONS: FHA does not correlate strictly with body weight variations in AN patients, indicating a multifactorial origin, likely including an individual predisposition. Higher FT3 levels identify patients who continue having menses at extremely low BMI. AN patients with persistent FHA constitute a subgroup in whom estroprogestins should be considered after significant weight recovery to prevent prolonged tissue hypoestrogenism.

Chorioretinal biomarkers in hypothalamic amenorrhea.

PURPOSE: The aim of our study was to evaluate changes in the retinal and choriocapillaris circulations in patients with hypothalamic amenorrhea. METHODS: Prospective, cross-sectional observational study on 25 patients (50 eyes) diagnosed with hypothalamic amenorrhea and 25 age-matched healthy women. Optical coherence tomography angiography (OCTA) was used to evaluate the vessel density (VD) of superficial capillary plexus (SCP), deep capillary plexus (DCP), and choriocapillaris VD layers in whole 6.4 × 6.4-mm image and in fovea grid-based image. In patients' group, systemic parameters were collected: body mass index (BMI), endometrial rhyme thickness, follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin, insulin, and cortisol. RESULTS: SCP and DCP did not show any statistical difference when comparing patients and controls (all p > 0.05). Differently, choriocapillaris VD in the whole region showed a non-significant tendency toward higher values in the patients group in both eyes (p = 0.038 for right eye [RE], p = 0.044 for left eye [LE]). Foveal choriocapillaris VD was higher in hypothalamic amenorrhea women vs. healthy controls (66.0 ± 2.4 vs. 63.7 ± 6.6%, p = 0.136 for RE; 65.0 ± 2.4 vs. 61.6 ± 7.0%, p = 0.005 for LE). Focusing on correlation with systemic parameters, SCP and DCP foveal density had a medium/high effect size with endometrial rhyme, along with DCP in the fovea area vs. cortisol and SCP in the whole area vs. FSH. CONCLUSION: When comparing hypothalamic amenorrhea patients to healthy subjects, OCTA detected changes in the choriocapillaris layer, showing increased VD in the early stage of the systemic pathology, suggesting that microvascular "compaction" could be a first phase of hypoestrogenism adaptation.

The impact of COVID-19 on menstrual cycle's alterations, in relation to depression and sleep disturbances: a prospective observational study in a population of medical students.

BACKGROUND: The sars-Cov-2 pandemic has determined psychological stress, particularly in the young population of medical students. We studied the impact of the pandemic on menstrual cycle alteration in relation to psychological stress, presence of depression, sleep disturbances and post-traumatic stress, on a population of medical students. METHODS: 293 female students at the Faculty of Medicine and Psychology of the Sapienza University of Rome (23.08 years old ± 3.8) were enrolled. In March 2021, one year after quarantine, a personal data sheet on menstrual cycle, examining the quality of the menstrual cycle during the pandemic, compared to the previous period. Concomitantly, the Beck Depression Inventory and the Impact of Event Scale have been administered. A Pearson chi-square test was assessed to evaluate the difference between the characteristics of the menstrual cycle and the scores obtained with the questionnaires. RESULTS: A statistically significant association between menstrual alterations and stress during pandemic had been found. The onset of depressive symptoms and sleep disturbances was observed in 57.1% and in 58.1% of young women with cycle's alterations, respectively. Amenorrhea was three times more common in female students with depressive symptoms, premenstrual syndrome had a significant correlation with both depression and sleep disturbances. The pandemic has been related to menstrual alterations, with depressive symptoms and sleep disorders. Amenorrhea is connected to depression, as observed on the functional hypothalamic amenorrhea. CONCLUSIONS: The pandemic affected the menstrual cycle as well as the depressive symptoms and sleep. Practical implications of the study lead to the development of strategies for psychological intervention during the pandemic experience, in order to help medical trainees, with specific attention to women's needs. Future studies should analyze the impact of other types of social stress events, on sleep, depression and the menstrual cycle beside the pandemic.

Menstrual cycle characteristics, perceived impact on performance, and barriers to communication: Perspectives of high-performance adolescent athletes in Singapore.

The purpose of this study was to examine the menstrual cycle (MC) characteristics, explore the impact on performance, and identify barriers to and facilitators of MC-related communication among high-performance female adolescent athletes in Singapore. Ninety athletes (15.4 ± 1.8 years) from multiple sports completed an online questionnaire. Eighty-four athletes were postmenarcheal (menarcheal age 11.9 ± 1.3 years), including two who were using an oral contraceptive pill (OCP). Secondary amenorrhea, current or history of, was self-reported in 16% of athletes. Sixty-two percent and 67% of non-OCP athletes perceived that the MC affected their ability to train and compete, respectively. Athletes preferred speaking to a parent (85%) and a female figure (67%) about MC-related concerns. Through thematic analysis, three barriers to communication were constructed: (1) pervasive menstrual stigma, (2) constraints of the training environment, and (3) the low value placed on MC-related conversations. Two facilitators of communication were constructed: (1) respect athletes' individual experiences as menstruating girls and (2) foster a safe space for MC-related conversations. Findings demonstrated that menstrual irregularities are common in adolescent athletes and screening for MC disorders, particularly primary amenorrhea should be undertaken in this population, with clear support pathways for management including symptom mitigation. To support athletes in raising MC-related concerns when needed, structured communication pathways that consider individual preferences and involve a (female) point of contact should be established within the training environment. Improving menstrual health literacy among adolescent athletes before any misinformation or negative perceptions are firmly established may contribute to longevity in their athletic careers.

Socioeconomic development predicts a weaker contraceptive effect of breastfeeding.

The contraceptive effect of breastfeeding remains essential to controlling fertility in many developing regions of the world. The extent to which this negative effect of breastfeeding on ovarian activity is sensitive to ecological conditions, notably maternal energetic status, has remained controversial. We assess the relationship between breastfeeding duration and postpartum amenorrhea (the absence of menstruation following a birth) in 17 World Fertility Surveys and 284 Demographic Health Surveys conducted between 1975 and 2019 in 84 low- and middle-income countries. We then analyze the resumption of menses in women during unsupplemented lactation. We find that a sharp weakening of the breastfeeding-postpartum amenorrhea relationship has globally occurred over the time period analyzed. The slope of the breastfeeding-postpartum amenorrhea relationship is negatively associated with development: higher values of the Human Development Index, urbanization, access to electricity, easier access to water, and education are predictive of a weaker association between breastfeeding and postpartum amenorrhea. Low parity also predicts shorter postpartum amenorrhea. The association between exclusive breastfeeding and maintenance of amenorrhea in the early postpartum period is also found in rapid decline in Asia and in moderate decline in sub-Saharan Africa. These findings indicate that the effect of breastfeeding on ovarian function is partly mediated by external factors that likely include negative maternal energy balance and support the notion that prolonged breastfeeding significantly helps control fertility only under harsh environmental conditions.

Prolactin levels in functional hypothalamic amenorrhea: a retrospective case-control study.

PURPOSE: Functional hypothalamic amenorrhea (FHA) is due to hypothalamic dysregulation. Literature lacks data about prolactin in FHA women, although both prolactin levels and FHA are associated with stress. Moreover, polycystic ovarian morphology is common in FHA and there is an association between FHA and polycystic ovary syndrome. Thus, the aim of this study was to assess prolactin levels in FHA patients and controls with a special focus on factors influencing prolactin levels, that could be considered as "sensors" of the hypothalamic-pituitary dysregulation. METHODS: In a retrospective cohort study, 140 women with clearly defined FHA were compared to 70 healthy, normally ovulating women matched for age. The main outcome parameter was prolactin. Factors associated with prolactin levels > 12 µg/L were tested using a multivariable binary logistic regression model. RESULTS: The median prolactin level was 11.5 µg/L (interquartile range, IQR 7.5-14.4), which was similar to the control group (median 10.7, IQR 8.3-14.5; p = 0.065). Only two women had hyperprolactinemia (prolactin > 25 µg/L; 1.4%). In a multivariable binary logistic regression model eating disorder (odds ratio, OR 0.206; p = 0.040), excessive exercise (OR 0.280; p = 0.031) and TSH (OR 1.923; p = 0.020) were significantly associated with prolactin levels > 12 µg/L. CONCLUSION: Women with FHA have similar prolactin levels to healthy age-matched individuals. Eating disorders and excessive exercise where associated with prolactin levels < 12 µg/L, in contrast to TSH.

Menstrual Irregularities and Amenorrhea in Thyroid Eye Disease Patients Treated With Teprotumumab.

PURPOSE: To evaluate the rates of amenorrhea and menstrual irregularities in patients with active thyroid eye disease treated with teprotumumab. METHODS: A retrospective review was conducted of patients with active thyroid eye disease treated between 2020 and 2022 at a single institution. Female thyroid eye disease patients with regular menstruation at baseline who completed 8 infusions of teprotumumab were assessed. Patient-reported irregularities in menstruation or amenorrhea were recorded during routine clinic visits. Two sample t tests were used to assess differences between patients endorsing and denying menstrual irregularities. RESULTS: Twelve patients met the inclusion criteria. The mean age was 38.33 ± 9.6 years (range 25-53 years). The average follow-up after treatment completion was 11.43 months. Nine patients (75%) reported changes from their baseline menstruation. Four patients (33.3%) reported irregularities during treatment only. Three patients (25%) had persistence of irregularities after treatment; these patients regained normal cycles at an average of 3 months following teprotumumab completion. Two patients (16.7%) did not regain their normal cycles at the time of their last follow-up. One 53-year-old patient-reported persistent amenorrhea after treatment completion. One patient-reported menorrhagia at a 4-month follow-up. No significant age difference was found between patients with or without reported menstrual changes ( p = 0.43). CONCLUSION: Abnormalities of menstruation, including amenorrhea, were reported by 75% of patients treated with teprotumumab. These changes reverted to baseline after treatment in most affected patients.

Menstrual characteristics of atypical anorexia nervosa.

OBJECTIVE: While menstrual irregularities are acknowledged in restrictive-type eating disorders (EDs), the menstrual characteristics specific to atypical anorexia nervosa (AAN) remain inadequately defined. This study aims to compare the menstrual features of anorexia nervosa (AN) and AAN. METHOD: Adolescents diagnosed with AN or AAN who exhibited secondary amenorrhoea at presentation and had their menstrual cycles restored during follow-up were eligible for this study. Clinical and menstrual data at admission and during follow-up were obtained from patient files, and compared between the AN and AAN cohorts. RESULTS: The study included a total of 77 patients (38 with AN and 39 with AAN). The extent of weight loss and the disease duration until the onset of amenorrhoea were comparable in the two groups. However, the duration of illness and the time since the last menstrual period at admission were shorter in the AAN group. Moreover, amenorrhoea manifested at a higher body mass index, and the return of menses occurred more rapidly with less weight gain in the AAN group after the onset of clinical follow-up. Additionally, the AAN group exhibited a shorter overall duration of amenorrhoea. CONCLUSIONS: This study highlights the significance of recognising amenorrhoea in restrictive disorders, even when individuals maintain a normal weight. The faster return of menstrual cycles and shorter duration of amenorrhoea observed in adolescents with AAN emphasise the significance of early diagnosis and prompt initiation of treatment. Regardless of the patient's presenting complaint and weight status, obtaining a comprehensive ED history is essential when addressing concerns regarding amenorrhoea or menstrual irregularities.

Primary amenorrhoea - cytogenetic study in 40 Indian women.

BACKGROUND: Primary amenorrhoea (PA) refers to an ailment when adolescent girls do not attain menarche naturally. It is one of the most common gynaecological disorders specified. Chromosomal abnormalities play a pivotal role in PA. Cytogenetic analysis is an indispensable diagnostic tool to determine the abnormality of the chromosome. In an emerging country like India, cytogenetic analysis is at a nascent stage. There are very few studies on Cytogenetics present in eastern India, including West Bengal. In rural and suburban areas PA sufferers often experience late diagnosis and struggle to access suitable curative management. The aim of the study is to evaluate the various types of chromosomal abnormalities in patients suffering from PA for accurate, better management of the same and further counselling. METHODS: A total of 40 PA cases were referred by obstetricians and gynaecologists to the Department of Genetics of Nirnayan Health Care, Kolkata. To screen the chromosomal abnormalities, human leukocyte culture was accomplished with their peripheral venous blood followed by G-banding and then karyotyping was executed according to ISCN-2020. RESULT: Out of 40 patients, 29 were normal among which 46,XX was found in 70% cases (n = 28) and 46,XX,9qh + in 2.5% (n = 1). The remaining 11 showed different types of abnormalities. 45,X was found in 10% (n = 4), 46,X,i(X)(q10) in 2.5% (n = 1), 46,X,del(X)(p11.2) in 2.5% (n = 1), 46,X,del(X)(p22.1) in 2.5% (n = 1), 46,X,del(X)(q24) in 2.5% (n = 1), 46,XY in 2.5% (n = 1), mos 45,X[22]/46,Xi(X)(q.10)[8] in 2.5% (n = 1) and mos 45,X[16]/46,XY[14] (2.5%) in 2.5% (n = 1). CONCLUSION: This study indicates the importance of chromosomal study which must be included in early diagnosis of PA. Karyotyping at the appropriate phase of life will not only help in the judicial management of this disorder but will also give young girls a better lifestyle.

Primary amenorrhoea is a common gynecological disorder reported in adolescent girls, often linked to chromosomal abnormalities. In Eastern India, including West Bengal, where cytogenetic analysis is still in its nascent stage, late diagnosis and limited access to curative management are prevalent issues. A study conducted from January 2021 to May 2023 at Nirnayan Healthcare, Kolkata aimed to evaluate chromosomal abnormalities in 40 PA cases. Out of these, 28 exhibited normal karyotypes (46,XX); one patient was reported with 46,XX,9qh + which is considered a normal karyotype, while the remaining 11 revealed diverse abnormalities, including 45,X; sex reversal & several structural variations. The study underscores the significance of cytogenetic analysis in the early diagnosis of Primary Amenorrhoea. Early karyotyping not only facilitates judicious management but also ensures a better lifestyle for affected girls.
