Shifting the landscape: Dominant C-terminal rare missense FOXL2 variants in non-syndromic primary ovarian failure etiology.

Pathogenic germline variants in the FOXL2 gene are associated with Blepharophimosis, Ptosis, and Epicanthus Inversus syndrome (BPES) in humans, an autosomal dominant condition. Two forms of BPES have emerged: (i) type I (BPES-I), characterized by ocular signs and primary ovarian failure (POI), and (ii) type II (BPES-II) with no systemic associations. This study aimed to compare the distribution of FOXL2 variants in idiopathic POI/DOR (diminished ovarian reserve) and both types of BPES, and to determine the involvement of FOXL2 in non-syndromic forms of POI/DOR. We studied the whole coding region of the FOXL2 gene using next-generation sequencing in 1282 patients with non-syndromic POI/DOR. Each identified FOXL2 variant was compared to its frequency in the general population, considering ethnicity. Screening of the entire coding region of the FOXL2 gene allowed us to identify 10 different variants, including nine missense variants. Of the patients with POI/DOR, 14 (1%) carried a FOXL2 variant. Significantly, six out of nine missense variants (67%) were overrepresented in our POI/DOR cohort compared to the general or specific ethnic subgroups. Our findings strongly suggest that five rare missense variants, mainly located in the C-terminal region of FOXL2 are high-risk factors for non-syndromic POI/DOR, though FOXL2 gene implication accounts for approximately 0.54% of non-syndromic POI/DOR cases. These results support the implementation of routine genetic screening for patients with POI/DOR in clinical settings.

Epigenetic/circadian clocks and PCOS.

Polycystic ovary syndrome (PCOS) affects 6-20% of reproductive-aged women. It is associated with increased risks of metabolic syndrome, Type 2 diabetes, cardiovascular diseases, mood disorders, endometrial cancer and non-alcoholic fatty liver disease. Although various susceptibility loci have been identified through genetic studies, they account for ∼10% of PCOS heritability. Therefore, the etiology of PCOS remains unclear. This review explores the role of epigenetic changes and modifications in circadian clock genes as potential contributors to PCOS pathogenesis. Epigenetic alterations, such as DNA methylation, histone modifications, and non-coding RNA changes, have been described in diseases related to PCOS, such as diabetes, cardiovascular diseases, and obesity. Furthermore, several animal models have illustrated a link between prenatal exposure to androgens or anti-Müllerian hormone and PCOS-like phenotypes in subsequent generations, illustrating an epigenetic programming in PCOS. In humans, epigenetic changes have been reported in peripheral blood mononuclear cells (PBMC), adipose tissue, granulosa cells (GC), and liver from women with PCOS. The genome of women with PCOS is globally hypomethylated compared to healthy controls. However, specific hypomethylated or hypermethylated genes have been reported in the different tissues of these women. They are mainly involved in hormonal regulation and inflammatory pathways, as well as lipid and glucose metabolism. Additionally, sleep disorders are present in women with PCOS and disruptions in clock genes' expression patterns have been observed in their PBMC or GCs. While epigenetic changes hold promise as diagnostic biomarkers, the current challenge lies in distinguishing whether these changes are causes or consequences of PCOS. Targeting epigenetic modifications potentially opens avenues for precision medicine in PCOS, including lifestyle interventions and drug therapies. However, data are still lacking in large cohorts of well-characterized PCOS phenotypes. In conclusion, understanding the interplay between genetics, epigenetics, and circadian rhythms may provide valuable insights for early diagnosis and therapeutic strategies in PCOS in the future.

Stratification of the risk of ovarian dysfunction by studying the complexity of intermediate and premutation alleles of the FMR1 gene.

FMR1 premutation female carriers are at risk of developing premature/primary ovarian insufficiency (POI) with an incomplete penetrance. In this study, we determined the CGG repeat size among 1095 women with diminished ovarian reserve (DOR) / POI and characterized the CGG/AGG substructure in 44 women carrying an abnormal FMR1 repeat expansion number, compared to a group of 25 pregnant women carrying an abnormal FMR1 CGG repeat size. Allelic complexity scores of the FMR1 gene were calculated and compared between the two groups. In the DOR/POI cohort, 2.1% of women presented with an intermediate repeat size and 1.9% with a premutation. Our results suggest that the risk of POI is highest in the mid-range of CGG repeats. We observed that the allelic score is significantly higher in POI women compared to the pregnant women group (p-value = 0.02). We suggest that a high allelic score due to more than 2 AGG interspersions in the context of an intermediate number of repetitions could favor POI. Larger studies are still needed to evaluate the relevance of this new tool for the determination of the individual risk of developing POI in women with abnormal number of CGG repeats.

NOBOX gene variants in premature ovarian insufficiency: ethnicity-dependent insights.

PURPOSE: Premature ovarian insufficiency (POI) affects approximately 1% of women before the age of 40. Genetic contribution is a significant component of POI. The NOBOX gene was considered one of the major genetic causes of POI. However, the pathogenicity and the penetrance of NOBOX variants remain unclear. METHODS: We studied the whole coding region of the NOBOX gene by next generation sequencing in a cohort of 810 patients with POI, and we compared the frequency of each identified NOBOX variant to the general population taking into account the ethnicity of each individual. RESULTS: Screening of the whole coding region of the NOBOX gene allowed us to identify 35 different variants, including 5 loss-of-function variants. In total, 171 patients with POI (25%) carried out at least one NOBOX variant. Regarding missense variants, we observed a significant overrepresentation of the most frequent ones in our 810 POI patients as compared to the general, except for p.(Arg117Trp). However, taking into account the ethnic origin of the individuals, we observed no significant OR difference for p.(Arg44Leu) and p.(Arg117Trp) in African subgroup and for p.(Asp452Asn) in European subgroup. CONCLUSION: This population study suggests that the p.(Arg44Leu) variant could be considered benign variant and that the p.(Asp452Asn) and p.(Arg117Trp) variants could be considered moderate risk pathogenic variants with probably partial and very low penetrance and/or expressivity. In contrast, p.(Gly91Trp) and p.(Gly152Arg) variants could be considered pathogenic variants with a moderate functional impact.

18F-fluorocholine PET/CT detects parathyroid gland hyperplasia as well as adenoma: 401 PET/CTs in one center.

BACKGROUND: During the past decade, 18F-fluorocholine (FCH) PET/CT has been continuously performed at Tenon Hospital (Paris, France) for the detection of hyperfunctioning parathyroid glands (PT). METHODS: A cohort of 401 patients, deliberately referred for HPT since September 2012, has been analyzed. The aim of this real-life retrospective study was to determine the diagnostic utility of FCH in this setting, overall and in subgroups according to the type of hyperparathyroidism (HPT), the context of FCH in the imaging work-up and in the patient's history: initial imaging or persistence or recurrence after previous parathyroidectomy (PTX). The influence of the histologic type of resected PTs, hyperplasia or adenoma, on the preoperatory detection on FCH PET/CT has been studied as well. RESULTS: Four hundred one FCH PET/CTs were included in the cohort, performed in 323 patients with primary HPT (pHPT), including 18 with familial HPT (fHPT), and in 78 patients with secondary renal HPT (rHPT). The overall positivity rate in the 401 FCH PET/CTs was 73%. The PTX rate was twice greater in patients whose FCH PET/CT was positive than negative (73% vs. 35%). Abnormal PT(s) were pathology proven in 214 patients: only hyperplastic gland(s) in 75 cases and at least one adenoma in 136 cases; FCH PET/CT sensitivity was 89% and 92%, respectively. Similarly, there was no significant difference in patient-based sensitivity whether FCH PET/CT was performed as 1st line or later in the imaging work-up, or indicated for initial imaging or for suspicion of persistent or recurrent HPT. Gland-based sensitivity was significantly lower for hyperplasia than for adenoma (72% and 86%, respectively). The lowest gland-based sensitivity value was 65%, observed in case of hyperplasia and when FCH was performed late in the imaging work-up. FCH PET/CT correctly showed multiglandular HPT (MGD) in 36/61 proven cases, 59%. Results of ultrasonography (US) and 99mTc-sestaMIBI (MIBI) imaging were available in 346 and 178 patients, respectively. For both modalities, the corresponding sensitivity values were significantly less than those of FCH PET/CT (e.g., overall gland-based sensitivity 78% for FCH, 45% for US, 30% for MIBI) and MGD was detected in 32% of cases by US and 15% by MIBI. CONCLUSIONS: Although FCH PET/CT has been performed since 2017 as 1st line imaging for HPT at Tenon Hospital (Paris, France), a large majority of patients underwent prior US and/or MIBI in their preoperative work-up. Therefore, a selection bias is very likely, as most patients referred to FCH PET/CT had non-conclusive or discordant results of US and MIBI, explaining the low performance of those modalities in the present cohort compared to published results. Nevertheless, the superiority of FCH PET/CT over US and MIBI in detecting abnormal PTs reported in various comparative studies is definitely confirmed in this larger real-life cohort. The detection with FCH PET/CT of hyperplastic PTs was somewhat lower than that of adenomas but was better than using US or MIBI. The present results lead to recommend FCH PET/CT as the first line imaging modality in HPT when it is widely available or, if less available, at least in HPT with predominance of hyperplasia and/or MGD.

Pituitary surgery outcome in patients 75 years and older: a retrospective study.

BACKGROUND: As the population ages, the number of elderly patients with an indication for pituitary surgery is rising. Information on the outcome of patients aged over 75 is limited. This study reports a large series assessing the feasibility of surgical resection in this specific age range, focusing on surgical complications and postoperative results. METHODS: A retrospective cohort study of patients with pituitary adenomas and Rathke's cleft cysts was conducted. All patients were aged 75 years or over and treated by a single expert neurosurgical team. A control population included 2379 younger adult patients operated by the same surgeons during the same period. RESULTS: Between 2008 and 2022, 155 patients underwent surgery. Indication was based on vision impairment in most patients (79%). Median follow-up was 13 months (range: 3-96). The first surgery was performed with an endoscopic transsellar approach, an extended endonasal transtuberculum approach and a microscopic transcranial approach in 96%, 3%, and 1% of patients, respectively. Single surgery was sufficient to obtain volume control in 97% of patients. From Kaplan-Meier estimates, 2-year and 5-year disease control with a single surgery were 97.3% and 86.2%, respectively. Resection higher than 80% was achieved in 77% of patients. No vision worsening occurred. In acromegaly and Cushing's disease, endocrine remission was obtained in 90% of non-invasive adenomas. Surgical complications were noted in 5% of patients, with 30-day mortality, hematoma, cerebrospinal fluid leak, meningitis, and epistaxis occurring in 0.6%, 0.6%, 1.9%, 0.6%, and 1.3% respectively. New endocrine anterior deficits occurred in only 5%, while no persistent diabetes insipidus was noted. Compared with younger patients, the complication rate was not statistically different. CONCLUSIONS: Surgery beyond the age of 75, mainly relying on an endoscopic endonasal transsellar approach, is effective and safe, provided that patients are managed in tertiary centers.

Multiple endocrine neoplasia type 1 or 4: detection of hyperfunctioning parathyroid glands with 18F-fluorocholine PET/CT. Illustrative cases and pitfalls.

18F-fluorocholine (FCH) PET/CT is now well established to detect the hyperfunctioning parathyroid glands (HFPTG) in a case of sporadic primary hyperparathyroidism (pHPT), but only limited evidence is available about the utility of FCH PET/CT to detect the HFPTG in patients with multiple endocrine neoplasia (MEN) type 1 or 4. The pHPT in this context frequently consists in a multiglandular disease with small hyperplastic glands rather than adenomas, which is challenging for imaging modalities. The data of patients with MEN1 or MEN4 after parathyroidectomy referred to FCH PET/CT for presurgical localization of HFPTG were retrospectively reviewed, including follow-up after parathyroidectomy, in search for diagnostic performance and for potential pitfalls. In the present cohort, 16 patients referred to FCH PET/CT as part of their initial pHPT work-up were subsequently operated, 44 abnormal parathyroid glands (PT) were resected, of which 32 (73%) had been detected on FCH PET/CT and 2 considered as equivocal foci. Nine patients referred to FCH PET/CT for recurrent pHPT who were subsequently operated, 14 abnormal PT were resected, all had been detected on FCH PET/CT. FCH PET/CT permitted a unilateral approach for PTx in 4 of them. In one patient with MEN4 and pHPT, the HFPTG could not be visualized on FCH PET/CT but was localized by ultrasonography. Several causes of false positive or false negative results, incidental finding and pitfalls are listed and discussed. FCH PET/CT has a positive benefit/risk ratio in the detection of HFPTG in case of MEN1 (the data in MEN4 being currently very limited) with the most effective detection rate of current imaging modalities for HFPTG, few pitfalls, and an adequate impact on patient management compared to sesta MIBI SPECT and ultrasonography.

Prevalence of lifetime eating disorders in infertile women seeking pregnancy with pulsatile gonadotropin-releasing hormone therapy.

OBJECTIVES: Relationships between weight and fertility are well known. The aim of this study is to assess the prevalence of lifetime eating disorder (ED) in a sample of infertile women seeking a specific infertility treatment, pulsatile gonadotropin-releasing hormone (pGnRH) treatment, and to compare it to the prevalence of lifetime ED in a sample of infertile women seeking other types of assisted reproductive technology (ART) treatments. DESIGN: Non-randomized, observational study including infertile female patients. Two-group design including consecutive women treated with GnRH pump (pGnRH) or with other types of ART. SETTING: Multi-centric infertility centers, France METHODS: Twenty one consecutive women treated with pGnRH treatment were compared to 21 consecutive women receiving other types of infertility treatment. Diagnosis of ED was based on DSM-IV and the Composite International Diagnostic Interview (CIDI). RESULTS: Twenty patients (95.2%) from the sample of women treated with pulsatile GnRH treatment and 5 patients (23.8%) from the patients receiving other types of infertility treatment met the criteria of lifetime ED diagnosis (p < 0.000). CONCLUSION: This study highlights the fact that the prevalence of ED is considerably higher in women receiving GnRH pulsatile treatment, when compared to women receiving other kinds of infertility treatment. In our study population ED were under-diagnosed, particularly in women receiving pulsatile GnRH treatment. Fertility clinicians should use reliable diagnostic tools to identify promptly ED in women presenting with hypothalamic amenorrhea and difficulties in conceiving. Level III: Evidence obtained from well-designed cohort or case-control analytic studies.

Mutations involving the SRY-related gene SOX8 are associated with a spectrum of human reproductive anomalies.

SOX8 is an HMG-box transcription factor closely related to SRY and SOX9. Deletion of the gene encoding Sox8 in mice causes reproductive dysfunction but the role of SOX8 in humans is unknown. Here, we show that SOX8 is expressed in the somatic cells of the early developing gonad in the human and influences human sex determination. We identified two individuals with 46, XY disorders/differences in sex development (DSD) and chromosomal rearrangements encompassing the SOX8 locus and a third individual with 46, XY DSD and a missense mutation in the HMG-box of SOX8. In vitro functional assays indicate that this mutation alters the biological activity of the protein. As an emerging body of evidence suggests that DSDs and infertility can have common etiologies, we also analysed SOX8 in a cohort of infertile men (n = 274) and two independent cohorts of women with primary ovarian insufficiency (POI; n = 153 and n = 104). SOX8 mutations were found at increased frequency in oligozoospermic men (3.5%; P < 0.05) and POI (5.06%; P = 4.5 × 10-5) as compared with fertile/normospermic control populations (0.74%). The mutant proteins identified altered SOX8 biological activity as compared with the wild-type protein. These data demonstrate that SOX8 plays an important role in human reproduction and SOX8 mutations contribute to a spectrum of phenotypes including 46, XY DSD, male infertility and 46, XX POI.

How can we make pregnancy safe for women with Turner syndrome?

Pregnancy is a crucial issue in patients with Turner syndrome (TS). Although natural pregnancies have been reported in 4-7% of TS patients, most women will need assisted reproductive technologies (ART) with oocyte donation. The main issue is the maternal mortality rate that is higher than in the general population. It is related to cardiovascular anomalies and particularly aortic dissection. TS, per se, is not a contraindication for pregnancy, but a multidisciplinary screening is mandatory before initiating a pregnancy. It includes repeated aortic diameters evaluation, blood pressure measurement and biological testing evaluating thyroid and liver functions, as well as blood glucose level. In order to make the pregnancy safe, contraindications of pregnancy should be respected and identification of high-risk patients for cardiovascular events should be performed. Hypertension and pre-eclampsia prevention may benefit from beta-blockers and aspirin, respectively. Collaborations between endocrinologists, cardiologists, and obstetricians are mandatory during pregnancy and even in the postpartum period. Counseling the patients about the risks of pregnancy, screening them and spreading the international guidelines to physicians taking care of patients with TS are the three pillars of a safe pregnancy.

An Application of NGS for Molecular Investigations in Perrault Syndrome: Study of 14 Families and Review of the Literature.

Perrault syndrome (PS) is a rare autosomal recessive condition characterized by deafness and gonadic dysgenesis. Recently, mutations in five genes have been identified: C10orf2, CLPP, HARS2, HSD17B4, and LARS2. Probands included are presented with sensorineural deafness associated with gonadic dysgenesis. DNA was sequenced using next-generation sequencing (NGS) with a panel of 35 deafness genes including the five Perrault genes. Exonic variations known as pathogenic mutations or detected with <1% frequency in public databases were extracted and subjected to segregation analysis within each family. Both mutations and low coverage regions were analyzed by Sanger sequencing. Fourteen female index patients were included. The screening in four cases has been extended to four family members presenting with PS phenotype. For four unrelated patients (28.6%), causative mutations were identified: three homozygous mutations in C10orf2, CLPP, and HARS2, and one compound heterozygous mutation in LARS2. Three additional heterozygous mutations in LARS2 and HSD17B4 were found in three independent familial cases. All these missense mutations were verified by Sanger sequencing. Familial segregation analyses confirmed the molecular diagnosis in all cases carrying biallelic mutations. Because of NGS, molecular analysis confirmed the clinical diagnosis of PS in 28.6% of our cohort and four novel mutations were found in four Perrault genes. For the unsolved cases, exome sequencing should be performed to search for a sixth unknown PS gene.

Intraadrenal corticotropin in bilateral macronodular adrenal hyperplasia.

BACKGROUND: Bilateral macronodular adrenal hyperplasia is a rare cause of primary adrenal Cushing's syndrome. In this form of hyperplasia, hypersecretion of cortisol suppresses the release of corticotropin by pituitary corticotrophs, which results in low plasma corticotropin levels. Thus, the disease has been termed corticotropin-independent macronodular adrenal hyperplasia. We examined the abnormal production of corticotropin in these hyperplastic adrenal glands. METHODS: We obtained specimens of hyperplastic macronodular adrenal tissue from 30 patients with primary adrenal disease. The corticotropin precursor proopiomelanocortin and corticotropin expression were assessed by means of a polymerase-chain-reaction assay and immunohistochemical analysis. The production of corticotropin and cortisol was assessed in 11 specimens with the use of incubated explants and cell cultures coupled with hormone assays. Corticotropin levels were measured in adrenal and peripheral venous blood samples from 2 patients. RESULTS: The expression of proopiomelanocortin messenger RNA (mRNA) was detected in all samples of hyperplastic adrenal tissue. Corticotropin was detected in steroidogenic cells arranged in clusters that were disseminated throughout the adrenal specimens. Adrenal corticotropin levels were higher in adrenal venous blood samples than in peripheral venous samples, a finding that was consistent with local production of the peptide within the hyperplastic adrenals. The release of adrenal corticotropin was stimulated by ligands of aberrant membrane receptors but not by corticotropin-releasing hormone or dexamethasone. A semiquantitative score for corticotropin immunostaining in the samples correlated with basal plasma cortisol levels. Corticotropin-receptor antagonists significantly inhibited in vitro cortisol secretion. CONCLUSIONS: Cortisol secretion by the adrenals in patients with macronodular hyperplasia and Cushing's syndrome appears to be regulated by corticotropin, which is produced by a subpopulation of steroidogenic cells in the hyperplastic adrenals. Thus, the hypercortisolism associated with bilateral macronodular adrenal hyperplasia appears to be corticotropin-dependent. (Funded by the Agence Nationale de la Recherche and others.).

Spontaneous fertility and pregnancy outcomes amongst 480 women with Turner syndrome.

STUDY QUESTION: What are the prevalence and the outcomes of spontaneous pregnancies (SP) in a large cohort of French women with Turner syndrome (TS)? SUMMARY ANSWER: Amongst 480 women with TS, 27 women (5.6%) had a total of 52 SP, with 30 full-term deliveries for 18 women. WHAT IS KNOWN ALREADY: Primary ovarian insufficiency is a classic feature of TS. So far, few studies have evaluated the rate of SP in these patients. STUDY DESIGN, SIZE, DURATION: The French Ministry of Health set up a National Reference Centre for Rare Growth Disorders (CRMERC), including TS. We studied a cohort of adult TS patients from seven endocrine units (Saint-Antoine, Pitié-Salpêtrière, Bicêtre, Lyon, Marseille, Brest, Reims Hospitals) belonging to this centre, between January 1999 and January 2014. PARTICIPANTS/MATERIALS, SETTING, METHODS: A total of 480 adult patients with TS were included. The patients' clinical characteristics, karyotypes and reproductive histories had been collected, after informed consent, in a web database called CEMARA. Our reference population was issued from a database belonging to the French Health Ministry, collecting pregnancy outcomes in the French general population. In order to find predictive characteristics of SP, TS with spontaneous pregnancies were compared with non-pregnant TS patients from our cohort. MAIN RESULTS AND THE ROLE OF CHANCE: There were 27 patients (5.6%) who had a total of 52 SP. The two predictive factors which correlated with occurrence of a SP were spontaneous menarche and mosaic karyotype. The median delay to conception was 6 months (range 0-84). Miscarriage occurred in 16 pregnancies, 30.8% versus 15% in the general French population (P < 0.01). The remaining pregnancy outcomes were legal abortion (n = 2), medical interruption (n = 3), intrauterine fetal death (n = 1) and delivery at term (n = 30). Caesarean section rates were higher than in the general population, respectively 46.7% versus 21% (P < 0.001). Pregnancy-induced hypertensive disorders (PHDs) occurred in four cases (13.3%), including two cases of mild pre-eclampsia (6.7%). Neither aortic root dilatation nor aortic dissection were observed. The median birthweight was 3030 g (range 2020-3460). Two cases of TS were identified in the 17 daughters issued from this cohort. LIMITATIONS, REASONS FOR CAUTION: It would have been interesting to evaluate AMH levels and SP occurrence, as a predictive factor. Unfortunately, hormonal measurements were missing for some patients. Prospective studies are necessary to display prognostic values of AMH for SP and thus better target fertility preservation programmes in TS patients. WIDER IMPLICATIONS OF THE FINDINGS: This study suggests that pregnancy outcomes in SPs are more favourable than those after oocyte donation in TS patients. However, the risk of fetal chromosomal abnormalities remains high. Our study will be useful in order to give patients with TS, their families, paediatricians and physicians involved in reproduction, better counselling concerning their fertility.

Toward a multi-country monitoring system of reproductive health in the context of endocrine disrupting chemical exposure.

BACKGROUND: Worrying trends regarding human reproductive endpoints (e.g. semen quality, reproductive cancers) have been reported and there is growing circumstantial evidence for a possible causal link between these trends and exposure to endocrine disrupting chemicals (EDCs). However, there is a striking lack of human data to fill the current knowledge gaps. To answer the crucial questions raised on human reproductive health, there is an urgent need for a reproductive surveillance system to be shared across countries. METHODS: A multidisciplinary network named HUman Reproductive health and Global ENvironment Network (HURGENT) was created aiming at designing a European monitoring system for reproductive health indicators. Collaborative work allowed setting up the available knowledge to design such a system. Furthermore we conducted an overview of 23 potential indicators, based upon a weight of evidence (WoE) approach according to their potential relation with EDC exposure. RESULTS: The framework and purposes of the surveillance system are settled as well as the approach to select suitable reproductive indicators. The indicators found with the highest scores according to the WoE approach are prostate and breast cancer incidence, sex ratio, endometriosis and uterine fibroid incidence, indicators related to the testicular dysgenesis syndrome, precocious puberty incidence and reproductive hormone levels. CONCLUSION: Not only sentinel health endpoints, but also diseases with high burdens in public health are highlighted as prior indicators in the context of EDC exposure. Our work can serve as a basis to construct, as soon as possible, the first multi-country reproductive monitoring system.

The CORALIE study: improving patient education to help new users better understand their oral contraceptive.

OBJECTIVES: Combined oral contraceptives (COCs) are the most widely used contraceptive method in Europe. Paradoxically, rates of unintended pregnancy and abortion are still remarkably high. A lack of knowledge about COCs is often reported to lead to poor adherence, suggesting an unmet need for adequate contraceptive counselling. Our objective was to investigate the impact on the knowledge level of users of a structured approach to deliver contraceptive information for a first COC prescription. METHODS: The Oral Contraception Project to Optimise Patient Information (CORALIE) is a multicentre, prospective, randomised study conducted in France between March 2009 and January 2013. The intervention involved providing either an 'essential information' checklist or unstructured counselling to new COC users. The outcome measure was a questionnaire that assessed whether the information provided to the new user by the gynaecologist had been correctly understood. RESULTS: One hundred gynaecologists and an expert committee used the Delphi method to develop an 'essential information' checklist, after which 161 gynaecologists were randomised to two groups. Group I (n = 81) used the checklist with 324 new COC users and group II (n = 80) delivered unstructured information to 307 new COC users. The average score for understanding the information delivered during the visit was significantly higher in women in group I than in the women in group II, even after adjustment for age and previous history of pregnancy: 16.48/20 vs 14.27/20 (p < 0.0001). CONCLUSION: Delivering structured information for a first COC prescription is beneficial for understanding contraception. Our tool could ultimately contribute to increased adherence and should be investigated in a prospective study of long-term outcomes.

Androgenic steroid excess in women.

Excessive use of anabolic-androgenic steroids (AAS) in sport occurs among professional athletes but increasingly also in amateurs. Prevalence of steroid use has been on the rise for a number of years. While the practice involves mostly men, it also occurs in women with an estimated prevalence of 1.6%. Since 2014, a 'steroid passport' has operated for sports people in competition that is based on longitudinal urinary and blood steroid levels, measured by liquid chromatography and mass spectrometry. Androgen excess stimulates muscle growth and improves muscle performance. However, their consumption carries numerous side effects, including myocardial hypertrophy; altered lipid metabolism and pro-thrombotic effects. The excess of AAS is associated with increased risk of atherosclerosis and cardiovascular events. Data for their effects in women is lacking. Perturbations of the menstrual cycle are common in female athletes, with spaniomenorrhea and even amenorrhea. This can be a consequence of gonadotropin insufficiency due to negative caloric balance, but may also be due to endogenous or exogenous hyperandrogenism. The use of AAS is probably underestimated as a public health issue, particularly in women, and thus presents a prevention challenge for healthcare professionals.

Fertility care among people with primary ciliary dyskinesia.

INTRODUCTION: Fertility care is important for people living with primary ciliary dyskinesia (PCD) who are at increased risk of fertility problems. We investigated fertility care in an international participatory study. METHODS: Participants of the COVID-PCD study completed an online questionnaire addressing fertility issues. We used logistic regression to study factors associated with fertility specialist visits. RESULTS: Among 384 respondents (response rate 53%), 266 were adults (median age 44 years, interquartile range [IQR]: 33-54, 68% female), 16 adolescents, and 102 parents of children with PCD. Only half of adult participants (128; 48%) received care from fertility specialists at a median age of 30 years (IQR: 27-33)-a median of 10 years after PCD diagnosis. Only 12% were referred to fertility specialists by their PCD physician. Fertility specialist visits were reported more often by adults with pregnancy attempts (odds ratio [OR]: 9.1, 95% confidence interval [CI]: 3.8-23.6) and among people who reported fertility as important for them (OR: 5.9, 95% CI: 2.6-14.6) and less often by females (OR: 0.4, 95% CI: 0.2-0.8). Only 56% of participants who talked with healthcare professionals about fertility were satisfied with information they received. They expressed needs for more comprehensive fertility information and reported dissatisfaction with physician knowledge about PCD and fertility. CONCLUSION: People with PCD are inconsistently referred to fertility specialists. We recommend care from fertility specialists become standard in routine PCD care, and that PCD physicians provide initial fertility information either at diagnosis or no later than transition to adult care.

Diagnostic and referral pathways in patients with rare lipodystrophy and insulin-resistance syndromes: key milestones assessed from a national reference center.

BACKGROUND: Rare syndromes of lipodystrophy and insulin-resistance display heterogeneous clinical expressions. Their early recognition, diagnosis and management are required to avoid long-term complications. OBJECTIVE: We aimed to evaluate the patients' age at referral to our dedicated national reference center in France and their elapsed time from first symptoms to diagnosis and access to specialized care. PATIENTS AND METHODS: We analyzed data from patients with rare lipodystrophy and insulin-resistance syndromes referred to the coordinating PRISIS reference center (Adult Endocrine Department, Saint-Antoine Hospital, AP-HP, Paris), prospectively recorded between 2018 and 2023 in the French National Rare Disease Database (BNDMR, Banque Nationale de Données Maladies Rares). RESULTS: A cohort of 292 patients was analyzed, including 208 women, with the following diagnosis: Familial Partial LipoDystrophy (FPLD, n = 124, including n = 67 FPLD2/Dunnigan Syndrome); Acquired lipodystrophy syndromes (n = 98, with n = 13 Acquired Generalized Lipodystrophy, AGL); Symmetric cervical adenolipomatosis (n = 27, Launois-Bensaude syndrome, LB), Congenital generalized lipodystrophy (n = 18, CGL) and other rare severe insulin-resistance syndromes (n = 25). The median age at referral was 47.6 years [IQR: 31-60], ranging from 25.2 (CGL) to 62.2 years old (LB). The median age at first symptoms of 27.6 years old [IQR: 16.8-42.0]) and the median diagnostic delay of 6.4 years [IQR: 1.3-19.5] varied among diagnostic groups. The gender-specific expression of lipodystrophy is well-illustrated in the FPLD2 group (91% of women), presenting with first signs at 19.3 years [IQR: 14.4-27.8] with a diagnostic delay of 10.5 years [IQR: 1.8-27.0]. CONCLUSION: The national rare disease database provides an important tool for assessment of care pathways in patients with lipodystrophy and rare insulin-resistance syndromes in France. Improving knowledge to reduce diagnostic delay is an important objective of the PRISIS reference center.

Gonadotropic status in adult women with pituitary stalk interruption syndrome.

OBJECTIVE: Pituitary stalk interruption syndrome (PSIS) is a rare cause of congenital hypopituitarism. Limited data exist on the gonadotropic status and fertility of adult women with PSIS. Our study aims to describe pubertal development and the evolution of gonadotropic function and fertility in adult women with PSIS. DESIGN: A retrospective multicentric French study. METHODS: We described gonadotropic function in 56 adult women with PSIS from puberty onward. We compared live birth rates per woman with PSIS with age-matched controls from the large French epidemiological cohort (CONSTANCES). Additionally, we assessed height, body mass index (BMI), blood pressure, other metabolic parameters, and socioeconomic status. RESULTS AND CONCLUSIONS: Among 56 women with PSIS, 36 did not experience spontaneous puberty. Of these, 13 underwent ovarian stimulation, resulting in 7 women having a total of 11 children. In the subgroup with spontaneous puberty (n = 20), 4 had a total of 8 pregnancies, while 6 developed secondary gonadotropic deficiency. Women with PSIS had fewer children than controls (0.33 vs 0.63, P = .04). Median height was also lower (160.5 vs 165.0 cm, P < .0001). Although mean blood pressure was lower in women with PSIS compared with controls (111.3/65.9 ± 11.2/8.1 vs 118.7/72.1 ± 10.1/7.7 mmHg, P < .001), there were no significant differences in other metabolic parameters, notably BMI and lipid profile. Employment/academic status was not different in the 2 groups, but fewer women with PSIS were in relationships (42% vs 57.6% in controls, P = .02). The fertility prognosis in patients with PSIS needs optimization. Patients should be informed about the likelihood of declining gonadotropic function over time.

Prognostic impact of hypothalamic perforation in adult patients with craniopharyngioma: a cohort study.

CONTEXT: Outcome of craniopharyngioma is related to its locoregional extension, which impacts resectability and the risk of surgical complications. To maximize resection and minimize complications, optic tract localization, temporal lobe extension and hypothalamic involvement are essential for surgical management. OBJECTIVE: To assess the outcome of craniopharyngiomas depending on their relation to the hypothalamus location. METHODS: We conducted a retrospective analysis of 79 patients with a craniopharyngioma who underwent surgery from 2007 to 2022. Craniopharyngiomas were classified in three groups, depending on the type of hypothalamus involvement assessed by preoperative MRI: infra-hypothalamic (type A, n=33); perforating the hypothalamus (type B, n=40); supra-hypothalamic (type C, n=6). Surgical strategy was guided by the type of hypothalamic involvement, favoring endonasal approaches for type A and type B, and transcranial approaches for type C. RESULTS: Long-term disease control was achieved in 33/33 (100%), 37/40 (92%) and 5/6 (83%) patients in type A, B and C respectively. In type B, vision was improved in 32/36 (89%) patients, while hypothalamic function was improved, stable or worsened in 6/40 (15%), 32/40 (80%) and 2/40 (5%) patients respectively. Papillary craniopharyngiomas were found in 5/33 (15%), 9/40 (22%) and 3/6 (50%) patients in types A, B and C respectively. In four patients, BRAF/MEK inhibitors were used, with significant tumor shrinkage in all cases. CONCLUSION: Craniopharyngiomas located below the hypothalamus or perforating it can be safely treated by transsphenoidal surgery. For supra-hypothalamic craniopharyngiomas, postoperative results are less favorable, and documenting a BRAF-mutation may improve outcome, if targeted therapy was efficient enough to replace surgical debulking.
