Longitudinal profile of estrogen-related thrombotic biomarkers after cessation of combined hormonal contraceptives.

ABSTRACT: The persistence of risk of venous thromboembolism (VTE) due to combined hormonal contraceptives (CHCs), after their cessation, is unknown but important to guide clinical practice. The objective of this prospective cohort study was to define the time until normalization of estrogen-related thrombotic biomarkers after CHC cessation. We enrolled women aged 18 to 50 years who had decided to stop their CHC, excluding those with a personal history of VTE, anticoagulation, or pregnancy. The study started before cessation of CHC, with 6 visits afterwards (at 1, 2, 4, 6, and 12 weeks after cessation). Primary outcomes were normalized sensitivity ratios to activated protein C (nAPCsr) and to thrombomodulin (nTMsr), with sex hormone-binding globulin (SHBG) as a secondary end point. We also included control women without CHC. Among 66 CHC users, from baseline until 12 weeks, average levels of nAPCsr, nTMsr, and SHBG decreased from 4.11 (standard deviation [SD], 2.06), 2.53 (SD, 1.03), and 167 nmol/L (SD, 103) to 1.27 (SD, 0.82), 1.11 (SD, 0.58), and 55.4 nmol/L (SD, 26.7), respectively. On a relative scale, 85.8%, 81.3%, and 76.2% of the decrease from baseline until 12 weeks was achieved at 2 weeks and 86.7%, 85.5%, and 87.8% at 4 weeks after CHC cessation, respectively. Levels were not meaningfully modified throughout the study period among 28 control women. In conclusion, CHC cessation is followed by a rapid decrease in estrogen-related thrombotic biomarkers. Two to 4 weeks of cessation before planned major surgery or withdrawal of anticoagulants in patients with VTE appears sufficient for the majority of women. The trial is registered at www.clinicaltrials.gov as #NCT03949985.

[News on progestatives in gynaecology]. / Actualités sur les progestatifs en gynécologie.

Progesterone (P4), a steroid primarily secreted by the corpus luteum, placenta and adrenal glands, plays an essential role on female reproductive function. Progestins (PS) are synthetic analogues of P4 with specific steroid receptor affinities. A progestin-only-pill (POP) with an antimineralocorticoid effect was recently marketed with a tolerance and safety profile superior to existing POPs. In contrast, PS with antiandrogenic properties used at high doses for the treatment of hirsutism have been associated with an increased meningioma risk. New clinical and fundamental data open paths for research into the therapeutic use of P4 in cognition, neuroprotection and bone.

La progestérone (P4), stéroïde sécrété principalement par le corps jaune, le placenta et les glandes surrénales, joue un rôle essentiel dans le contrôle de la fonction reproductive de la femme. Les progestatifs de synthèse (PS) sont des analogues avec des affinités spécifiques sur les divers récepteurs stéroïdiens. Une pilule progestative (POP) aux effets antiminéralocorticoïdes a récemment été commercialisée avec un profil de tolérance et de sécurité supérieur aux POP existants. En revanche, des PS aux propriétés antiandrogènes utilisés en forte dose pour le traitement de l'hirsutisme ont été associés à un risque accru de méningiome. De nouvelles données cliniques et fondamentales ouvrent de nouvelles voies de recherche sur l'utilisation thérapeutique de la P4 dans les champs de la cognition, de la neuroprotection et de l'os.

Migraine in relation with endometriosis phenotypes: Results from a French case-control study.

BACKGROUND: Studies have shown a significant association between migraine and endometriosis, but no study has explored the relationship between migraine and endometriosis phenotypes: Superficial peritoneal endometriosis, ovarian endometrioma, and deep infiltrating endometriosis. METHODS: We conducted a case-control study using data collected from 314 women aged 18 to 42 years who had undergone surgery for benign gynecological conditions between January 2013 and December 2015. All women completed a self-administered headache questionnaire according to the IHS classification. Cases (n = 182) are women with histologically proven endometriosis and controls are women (n = 132) without endometriosis. Occurrence of migraine was studied according to endometriosis phenotypes. RESULTS: Migraine prevalence in cases was significantly higher compared with controls (35.2% vs. 17.4%, p = 0.003). The risk of endometriosis was significantly higher in migrainous women (OR = 2.62; 95% CI = 1.43-4.79). When we take into account endometriosis phenotypes, the risk of ovarian endometrioma and deep infiltrating endometriosis were significant (OR = 2.78; 95% CI = 1.11-6.98 and OR = 2.51; 95% CI = 1.25-5.07, respectively). In women with endometriosis, the intensity of chronic non-cyclical pelvic pain was significantly greater for those with migraine (visual analogic scale (VAS) = 3.6 ± 2.9) compared with the women without headache (VAS = 2.3 ± 2.8, p = 0.0065). CONCLUSION: Our study shows a significant association between migraine and endometriosis. In clinical practice, women of reproductive age who suffer from migraine should be screened for endometriosis criteria in order to optimise the medical and therapeutic care of this condition.

The effect of mind-body interventions on psychological and pregnancy outcomes in infertile women: a systematic review.

Preliminary evidence suggests that mind-body interventions, including mindfulness-based interventions and yoga, may be effective in reducing mental health difficulties and psychological distress in infertile patients undergoing fertility treatments. We systematically reviewed and synthesized current medical literature of the effectiveness of mind-body interventions in reducing the severity of psychological distress and improving marital function and pregnancy outcomes in infertile women/couple. Databases including PsychINFO, PubMed, EMBASE, and the Cochrane Library were searched for relevant studies. Manual searches were conducted in relevant articles. We included 12 studies that met the inclusion criteria. Four studies were randomized controlled trials (RCT), 4 non-randomized controlled trial (NRCT), and 4 uncontrolled studies (UCT). Participation in a mind-body intervention was associated with reduced anxiety trait and depression scores. The reduction was of low or moderate amplitude in most studies. Our review offers evidence for the effectiveness of mind-body interventions in reducing anxiety state and depression in infertile women and a possible improvement in pregnancy rate. Further RCTs with a precise timing of intervention are needed.

[Contraception and venous thromboembolism]. / Contraception et maladie thromboembolique veineuse.

Combined oral contraceptives remain in 2020 the most used contraceptive method in Switzerland and Europe, and are found in about half of venous thromboembolism (VTE) occurring in women aged up to 50 years. In this narrative review, we describe the determinants of the VTE risk, related to the types of oral contraceptives and to genetic or acquired risk factors of users, while summarizing several current recommendations of prescription for contraceptives. The complex management of contraception at the time of VTE should be discussed with patients, in order to minimize the risks of undesired pregnancy, abnormal uterine bleeding and recurrent VTE.

En 2020, la contraception orale combinée reste la méthode contraceptive la plus utilisée en Suisse et en Europe, et son usage est retrouvé dans environ la moitié des événements de maladie thromboembolique veineuse (MTEV) des femmes de moins de 50 ans. Dans cette revue narrative, nous décrivons les déterminants du risque de MTEV en fonction du type de contraceptif et des facteurs de risque acquis ou génétiques des utilisatrices, en se basant sur les recommandations actuelles de prescription. La gestion de la contraception lors d'un événement de MTEV reste complexe et doit alors être discutée avec la patiente, afin de minimiser les problèmes de grossesse non désirée, de ménorragies et de récidive thromboembolique.

Obstetrical and postpartum complications in women with hereditary fibrinogen disorders: A systematic literature review.

INTRODUCTION: Hereditary fibrinogen disorders (HFD) are rare quantitative or qualitative fibrinogen anomalies, including afibrinogenaemia (A), hypofibrinogenaemia (H), dysfibrinogenaemia (D) and hypodysfibrinogenaemia (HD). As fibrinogen plays an essential role in pregnancy, we addressed the issue of obstetrical and postpartum complications in women with HFD. METHODS: A systematic literature review, restricted to English manuscripts, was conducted according to the PRISMA guidelines. We searched through the MEDLINE database for English articles, published from January 1985 until November 2018, focusing on pregnancy in A, H, D and HD. A total of 198 articles were identified, 15 articles were added from other sources. Overall, 213 articles were screened and 54 were included in the final analysis. RESULTS: A total of 188 pregnancies from 70 women were analysed. About half of pregnancies resulted in miscarriage; more specifically in 15 (42.9%), 36 (46.8%), 27 (42.9%) and 4 (30.8%) of A, H, D and HD patients, respectively. Preterm complications were also frequent (33.5%). Metrorrhagia, mainly in the first trimester, was observed in 21.7% of the pregnancies. Placenta abruption was reported in 5 (14.3%), 4 (5.2%), 5 (7.9%) and 1 (7.7%) of A, H, D and HD, respectively. A total of 24 (12.7%) deliveries were complicated by postpartum thrombotic events (3.2%) or postpartum haemorrhage (9.6%). A fibrinogen replacement therapy was introduced in 30% of pregnancies, as prophylaxis (81.1%) or on demand (18.9%). CONCLUSION: These results suggest that women with HFD are at high risk of obstetrical and postpartum complications. Prospective international registries may allow to identify more precisely the incidence of obstetrical and postpartum adverse outcomes and their management.

[Hormonal contraception and vascular risk]. / Contraception hormonale et risque vasculaire.

Hormonal contraception and vascular risk. Since the early 1960, it has been well documented that combined hormonal contraceptives (CHC) increase the risk of venous thromboembolism diseases (VTE) and arterial diseases, even if it is an uncommon disease before menopause. Vascular risk is the most important determinant of the benefit/ risk profile of hormonal contraceptive. The most recent pills are associated with a higher risk of VTE than second- generation pill. CHC increase the risk of arterial disease (myocardial infarction or ischemic stroke), especially in women at high vascular risk. This increase does not depend on the generation of CHC. A meticulous research of vascular risk factors, including familial history of VTE, is recommended before prescription. It allows to adapt the contraceptive strategy for every woman according to the bene- fit/risk profile. In context of high vascular risk, low doses of both oral progestin contraceptives and intrauterine levonorgestrel could be safe with respect to VTE risk.

Contraception hormonale et risque vasculaire. La contraception hormonale demeure la contraception la plus utilisée en France. Les événements vasculaires représentent les principaux effets délétères de la contraception estroprogestative ou contraception hormonale combinée. De très nombreuses études épidémiologiques ont analysé le lien entre l'utilisation d'une contraception hormonale et le risque vasculaire. Les pilules les plus récentes sont associées à un risque de thrombose veineuse plus important que les pilules dites de 2e génération, contenant du lévonorgestrel. La contraception hormonale combinée, quel qu'en soit le type, augmente le risque d'accident artériel. Une recherche minutieuse des facteurs de risque, notamment des antécédents familiaux de thrombose, est recommandée avant toute prescription mais aussi lors du suivi. Une stratégie contraceptive doit être proposée et adaptée à chaque situation clinique afin d'en optimiser la balance béné- fice-risque. La contraception combinée est contre-indiquée formellement chez les femmes à haut risque vasculaire quelle que soit la voie d'administration et quel que soit le type d'estrogène ou de progestatif combiné. Dans ce contexte, les contraceptions progestatives - en dehors la contraception injectable - sont, dans la plupart des cas, autorisées.

First mutation in the FSHR cytoplasmic tail identified in a non-pregnant woman with spontaneous ovarian hyperstimulation syndrome.

BACKGROUND: Spontaneous ovarian hyperstimulation syndrome (sOHSS) is a rare event occurring mostly during natural pregnancy. Among described etiologies, some activating mutations of FSH receptor (FSHR) have been identified. CASE PRESENTATION: We report hereby the case of a non-pregnant women with three episodes of sOHSS. Hormonal evaluation was normal and no pituitary adenoma was detected. However, genetic analysis identified a novel heterozygous FSHR mutation (c.1901 G > A). This R634H mutation is the first described in the cytoplasmic tail of the receptor. Functional analysis failed to reveal constitutive activity of the mutant but a decreased cAMP production in response to FSH. The weak activity of this mutant is correlated with a markedly reduced cell surface expression. CONCLUSION: Pathophysiology of non gestationnal sOHSS is still ill established. The molecular characterization of this new mutant indicates that it might not be at play. Therefore, further investigations are needed to improve knowledge of the molecular mechanism of this syndrome.

Sex hormone-binding globulin and thrombin generation in women using hormonal contraception.

OBJECTIVES: We investigated the impact of serum sex hormone-binding globulin (SHBG) on thrombin generation (TG) in women according to hormonal contraception. PATIENTS AND METHODS: A cross-sectional study of SHBG and TG measured via calibrated automated thrombography was conducted in 150 healthy women, including 75 users of combined oral contraceptives (COC), 22 users of progestin-only contraceptives (POC) and 53 nonusers. RESULTS: COC but not POC-users had significantly higher SHBG levels compared with nonusers. In hormonal contraceptive users, SHBG was positively associated with both activated protein C (APC) resistance and baseline TG, and protein S and prothrombin were important mediators. CONCLUSION: These data provide further evidence that SHBG may be used as a biomarker in assessing prothrombotic profile of hormonal contraception.

[Hormonal treatments and venous thrombosis in women]. / Traitements hormonaux et risque de thrombose veineuse chez la femme.

Venous thromboembolism is frequently associated with hormonal factors in women. A thorough medical history taking of vascular risks and an individual evaluation of the risk-benefit ratio should precede any prescription of hormonal therapies. In contrary to progestin-only-pills, estroprogestative contraceptives increase 3-6 times the risk of venous thrombosis. In assisted reproductive techniques, venous thrombosis is frequently associated with the occurrence of a severe ovarian hyperstimulation syndrome. Antagonist ovarian stimulation protocols lower the risk of hyperstimulation and should therefore be preferred. Finally, at menopause, hormonal treatments combining transdermal estradiol and micronized progesterone do not seem to increment the risk of thrombosis.

La maladie veineuse thromboembolique est fréquemment associée aux facteurs hormonaux chez la femme. La prescription de toute thérapeutique hormonale sera précédée d'un interrogatoire minutieux à la recherche de facteurs de risque vasculaires et d'une évaluation individuelle de la balance bénéfice-risque. Contrairement à la contraception micro-progestative, la contraception œstroprogestative augmente le risque de thrombose veineuse de 3 à 6 fois. En procréation médicalement assistée, la thrombose veineuse est fréquemment associée à la survenue d'un syndrome d'hyperstimulation ovarienne sévère. Les protocoles de stimulation antagonistes minimisant le risque d'hyperstimulation ovarienne sont donc à privilégier. Enfin, après la ménopause, le traitement hormonal associant de l'œstradiol par voie percutanée et de la progestérone micronisée ne semble pas augmenter le risque de thrombose veineuse.

MR diagnosis of diaphragmatic endometriosis.

PURPOSE: To evaluate magnetic resonance imaging (MRI) for diaphragmatic endometriosis diagnosis. MATERIALS AND METHODS: Over a 2-year period, all diaphragmatic MRI performed in the context of diaphragmatic endometriosis were reviewed. Axial and coronal fat-suppressed T1- and T2-weighted sequences were analyzed by two independent readers for the presence of nodules, plaque lesions, micronodule clustering, or focal liver herniation. MR abnormalities were correlated to surgical findings in women surgically treated. Interobserver agreement was assessed by κ statistics. RESULTS: Twenty-three women with diaphragmatic endometriosis criteria comprised the population; 14 had surgical confirmation and nine had symptoms relief with hormonal treatment. MRI sensitivity was 83 % (19/23; 95 % confidence interval [CI]: 68, 98) for reader 1 and 78 % (18/23; 95 % CI: 61, 95) for reader 2. Kappa value was 0.86 (95 % CI: 0.47, 1.00). Readers 1 and 2 detected 35 and 36 lesions, respectively, all right-sided and agreed for 32 lesions on the type, location, and signal. Lesions were mostly nodules (23/32, 72 %), predominantly posterior (28/32, 87.5 %) and hyperintense on T1 (20/32, 63 %). MRI was negative for both readers in 2 surgically treated patients with small nodules or isolated diaphragmatic holes. CONCLUSION: MRI allows diaphragmatic endometriosis diagnosis with 78 to 83 % sensitivity and excellent interobserver agreement. KEY POINTS: • MRI allows the diagnosis of diaphragmatic endometriosis with up to 83 % sensitivity. • Diaphragmatic endometriosis lesions are better depicted on fat-suppressed T1-weighted sequences. • Diaphragmatic lesions, mostly hyperintense nodules, are right-sided and predominantly posterior. • MRI can help in timely diagnosis of diaphragmatic endometriosis.

Inhibin A and inhibin B producing ovarian fibrothecoma revealed by suppression of follicle stimulating hormone (FSH) in a post-menopausal woman: report of the first case.

In this report, we describe the first case ever reported in the literature, of an inhibin-A (INHA) and inhibin-B (INHB) producing fibrothecoma. A post-menopausal woman was referred to our unit because of follicle stimulating hormone (FSH) level below the reference interval for postmenopausal women. By contrast luteinizing hormone, hCG, and estradiol levels were within normal range. This discrepancy suggested the secretion of FSH inhibitory factors. INHB and INHA levels were markedly elevated for age, 475 pg/mL and 100 pg/mL, respectively. Ultrasonography and MRI showed a pelvic mass of indeterminate nature. Abnormal inhibin secretion is generally observed in granulosa cell tumors. In this case this etiology was unlikely because of low estradiol and AMH levels. Surgical exploration revealed a 10 cm mass of the left ovary proven histologically to be an ovarian fibrothecoma (OFT). After tumor removal, INHB and INHA levels decreased rapidly. Only three cases of OFT with an important secretion of INHB have been reported to date. INHA secretion has never been associated with OFT. There is a need to develop coupled hormone and imaging strategies to diagnose the source of INH secretion in case of FSH/LH discrepancy.

Loss of glucocorticoid receptor activation is a hallmark of BRCA1-mutated breast tissue.

Glucocorticoids (GCs) regulate cell homeostasis and can affect carcinogenesis. An inherited germline mutation in the BRCA1 gene, a tumor suppressor gene, confers a predisposition to breast and ovarian cancers. BRCA1 participates in the maintenance of genome stability through DNA repair, in cellular homeostasis through gene transcription, and in signaling regulation. The interaction between BRCA1 and the glucocorticoid receptor (GR) signaling pathway was studied in normal breast tissues and triple-negative breast cancers from BRCA1 mutation carriers. A loss of the active Ser211 phosphorylated form of GR was found in the mutant as compared to the non-mutant. In in vitro studies, the BRCA1 status in breast cancer cell lines regulates GC-dependent proliferation/apoptosis and impacts GC-dependent gene expression. The lack of BRCA1 inhibited dexamethasone actions on its target genes' expression and the opposite effect was seen with BRCA1 overexpression. BRCA1 overexpression enhances MAPK p38 phosphorylation, resulting in an amplification of GR phosphorylation on Ser 211 and GR basal expression. Our results indicate that BRCA1 is essential to develop an efficient GC signalization. GR P-Ser211 levels may constitute an important diagnostic factor for screening BRCA1 loss of expression in tumors from BRCA1 mutation carriers as well as in sporadic BRCAness tumors. This marker may help to optimize therapeutic strategies.

Prothrombotic biomarkers during controlled ovarian stimulation for assisted reproductive technology.

OBJECTIVE: To assess the impact of 3 different ovarian stimulation protocols on surrogate biomarkers of coagulation. DESIGN: Observational multicenter cohort study. SETTING: The study was conducted in assisted reproductive technology (ART) units. PATIENTS: Infertile women undergoing ART in 2017-2019 were included. INTERVENTIONS: None. MAIN OUTCOME MEASURE(S): Our primary outcome was the endogenous thrombin potential (ETP) assessed by the calibrated automated thrombogram. The ETP was measured at baseline (T1), on the day of ovulation triggering (T2), and 7 days after triggering (T3). Three protocols were prescribed according to the standards used and without hormonal before treatment: agonist protocol with human chorionic gonadotropin (hCG) trigger (ag-hCG), antagonist protocol with hCG trigger (atg-hCG), or GnRH agonist trigger. The evolution of ETP was compared among groups using a mixed-effects linear regression model. RESULT(S): Sixty-four women with a mean age of 37.8 years participated in the study: of which 24, 16, 24 received ag-hCG, atg-hCG, and GnRH agonist triggers, respectively. As expected, the mean serum estradiol levels in GnRH agonist trigger were statistically higher at T2 and lower at T3 than that for both ag-hCG and atg-hCG. Overall, the ETP evolution over time was statistically different between the groups. Values were similar between groups at T1 and increased at T2 in each group. The greatest difference occurred between T2 and T3 in each group. The ETP continued to increase at T3 in ag-hCG (+110 nM/L × min) and atg-hCG (+171 nM/L × min), but it remained stable in GnRH agonist trigger (-2 nM/L × min). Sex hormone-binding globulin showed persistent increase at T3 despite the fall in estradiol levels, particularly in the GnRH agonist trigger group. CONCLUSION(S): The ag-hCG and atg-hCG groups were associated with a higher hypercoagulable state at T3 than the GnRH agonist trigger group. However, our results show the persistence of a hypercoagulable state after the GnRH agonist triggering despite a sharp drop in estradiol levels. These findings may support the use of GnRH agonist trigger protocol in patients with high thrombotic risk and gives new insight into the fact that coagulation parameters could be disturbed for long time periods. CLINICAL TRIAL REGISTRATION NUMBER: NCT04188444.

Obstetrical complications in hereditary fibrinogen disorders: the Fibrinogest study.

BACKGROUND: Women with hereditary fibrinogen disorders (HFDs) seem to be at an increased risk of adverse obstetrical outcomes, but epidemiologic data are limited. OBJECTIVES: We aimed to determine the prevalence of pregnancy complications; the modalities and management of delivery; and the postpartum events in women with hypofibrinogenemia, dysfibrinogenemia, and hypodysfibrinogenemia. METHODS: We conducted a retrospective and prospective multicentric international study. RESULTS: A total of 425 pregnancies were investigated from 159 women (49, 95, and 15 cases of hypofibrinogenemia, dysfibrinogenemia, and hypodysfibrinogenemia, respectively). Overall, only 55 (12.9%) pregnancies resulted in an early miscarriage, 3 (0.7%) resulted in a late miscarriage, and 4 (0.9%) resulted in an intrauterine fetal death. The prevalence of live birth was similar among the types of HFDs (P = .31). Obstetrical complications were observed in 54 (17.3%) live birth pregnancies, including vaginal bleeding (14, 4.4%), retroplacental hematoma (13, 4.1%), and thrombosis (4, 1.3%). Most deliveries were spontaneous (218, 74.1%) with a vaginal noninstrumental delivery (195, 63.3%). A neuraxial anesthesia was performed in 116 (40.4%) pregnancies, whereas general or no anesthesia was performed in 71 (16.6%) and 129 (44.9%) pregnancies, respectively. A fibrinogen infusion was administered in 28 (8.9%) deliveries. Postpartum hemorrhages were observed in 62 (19.9%) pregnancies. Postpartum venous thrombotic events occurred in 5 (1.6%) pregnancies. Women with hypofibrinogenemia were at an increased risk of bleeding during the pregnancy (P = .04). CONCLUSION: Compared with European epidemiologic data, we did not observe a greater frequency of miscarriage, while retroplacental hematoma, postpartum hemorrhage, and thrombosis were more frequent. Delivery was often performed without locoregional anesthesia. Our findings highlight the urgent need for guidance on the management of pregnancy in HFDs.

Ulipristal acetate does not impact human normal breast tissue.

BACKGROUND: Antiprogestins are of growing interest for the development of new treatments in the gynecological field. Ulipristal acetate (UPA) is a progesterone receptor (PR) modulator considered for long-term administration in contraception and is currently being registered for the treatment of uterine fibroids. In light of the influences of hormonal dysfunction in breast pathologies, the secondary consequences of chronic UPA therapy need to be established. The aim of this study was to determine UPA actions mediated by PR and glucocorticoid receptor (GR) in normal and transformed breast. METHODS: UPA, progesterone (P) and dexamethasone (DEX) effects were observed on PR and GR responsive genes and on proliferation and apoptosis of normal human breast epithelial (HBE) and breast cancer cells. Human normal breast tissue samples were xenografted in athymic mice and treated with estradiol (E2), or E2 + P, or E2 + P + UPA. RESULTS: Analysis of PR and GR reporter gene transactivation and their respective endogenous target genes indicated that UPA exerted anti-progestational and anti-glucocorticoid activity in both types of cells with a more pronounced effect in cancer cells. When combined with P or DEX, UPA limits the proliferation of HBE cells but increases growth in breast cancer cell lines. UPA administration had no impact on the mitotic index on xenografted human breast tissue exposed to gonadal hormones at similar concentrations to those present in normal women. CONCLUSIONS: Although further clinical trials are required to confirm that the results from our experimental models can be extrapolated to women treated with UPA, they suggest that such treatment would not be deleterious to normal breast tissue at least for a cycle (28 days) of continuous administration.

Management of granulomatous mastitis: a series of 14 patients.

OBJECTIVE: To analyze the history of relapses in idiopathic granulomatous mastitis (IGM) and to define an appropriate therapeutic strategy. The duration and number of relapses are unpredictable, and the roles of surgery and corticosteroids remain controversial. STUDY DESIGN: A series of 14 patients with IGM and a mean follow-up of 61.5 ± 73 (SD) months were retrospectively studied in the Gynecology Unit (Hotel Dieu Hospital, Paris, France). Main outcome measure was number of relapses per year before and following corticosteroid therapy. Comparison of the two groups was performed with matched t-test. RESULTS: A total of 125 episodes were analyzed. Before steroid treatment, 60 recurrences occurred, corresponding to a mean of 4.03 ± 4.22 (SD) relapses per year. After the first treatment with prednisone, patients experienced 47 relapses, representing a mean of 1.11 ± 1.27 (SD) relapses per year (p = 0.0371). CONCLUSIONS: Medical treatment with steroid reduces the duration and number of episodes. It also prevents the need for invasive breast surgery.

Next Generation Sequencing Should Be Proposed to Every Woman With "Idiopathic" Primary Ovarian Insufficiency.

CONTEXT: Primary ovarian insufficiency (POI) affects 1% of women under 40 years of age. POI is idiopathic in more than 70% of cases. Though many candidate genes have been identified in recent years, the prevalence and pathogenicity of abnormalities are still difficult to establish. OBJECTIVE: Our primary objective was to evaluate the prevalence of gene variations in a large prospective multicentric POI cohort. Our secondary objective was to evaluate the correlation between phenotype and genotype. METHODS: Two hundred and sixty-nine well-phenotyped POI patients were screened for variants of 18 known POI genes (BMP15, DMC1, EIF2S2, FIGLA, FOXL2, FSHR, GDF9, GPR3, HFM1, LHX8, MSH5, NOBOX, NR5A1, PGRMC1, STAG3, XPNPEP2, BHLB, and FSHB) by next generation sequencing (NGS). Abnormalities were classified as "variant" or "variant of unknown signification" (VUS) according to available functional tests or algorithms (SIFT, Polyphen-2, MutationTaster). RESULTS: One hundred and two patients (38%) were identified as having at least 1 genetic abnormality. Sixty-seven patients (25%) presented at least 1 variant. Forty-eight patients presented at least 1 VUS (18%). Thirteen patients (5%) had combined abnormalities. NOBOX variants were the most common gene variants involved in POI (9%). Interestingly, we saw no significant differences in the previous family history of POI, ethnic origin, age at onset of POI, primary amenorrhea, or secondary menstrual disturbances between the different genotypes. CONCLUSION: In our study, a high percentage of patients presented gene variants detected by NGS analysis (38%). Every POI patient should undergo NGS analysis to improve medical cares of the patients.
