Lack of evidence that progesterone in ovulatory cycles causes breast cancer.

A recent Perspective article asserted that progesterone secretion during ovulatory cycles is the cause of breast cancer. However, we challenge most of the evidence developed in this publication. First, there is a lack of evidence that progesterone is mutagenic for breast cells. Cause of a cancer should mean initiation by mutation, as opposed to promotion. Second, subclinical ovulatory disturbances occur rather frequently in normal-length menstrual cycles. Third, the authors attribute a potential carcinogenic effect to progesterone secreted during menstrual cycles but not to progesterone during pregnancy. They did not discuss breast cancer evidence from progesterone/progestin therapeutics. They argue that in genetic primary amenorrhea, a hypothetic lower risk of breast cancer could be due to the lack of progesterone, despite the progesterone/progestin in hormone replacements these women receive. Fourth, they advocate a regulatory effect of progesterone on several genes potentially involved in cancer genesis. In particular, they attribute a lower risk of breast cancer in women with Mayer-Rokitansky-Küster-Hauser syndrome to a defect in the progesterone-stimulated Wnt4 gene. However, this defect is only present in a small subset. Thus, the postulated progesterone breast cancer risk is unconvincing, which we discuss point by point in this commentary.

Menopause hormone treatment after cancer.

Regular improvement in survival of women after treatment for cancer has been reached in these last years. Menopause hormone therapy (MHT) remains the most efficient treatment to alleviate climacteric symptoms and improve quality of life in symptomatic women. The long-term effects of estrogen deficiency can be, at least partially, prevented by MHT. However, using MHT in an oncologic context can be associated with contraindications. Patients who have experienced breast cancer frequently face severe climacteric symptoms, but results from randomized trials are not in favor of using MHT in these women. Three randomized trials are available in women treated by MHT after ovarian cancer, and report better survival rates in the active group of treatment, suggesting that, at least in serous high-grade ovarian carcinoma, MHT could be allowed. No robust data are available for MHT after endometrial carcinoma. According to various guidelines, MHT could be possible in low grades with good prognosis. Progestogen, however, is not contraindicated and can help to alleviate climacteric symptoms. Squamous cell cervical carcinoma is not hormone-dependent and therefore patients can be treated with MHT without restrictions, whereas cervical adenocarcinoma is likely to be estrogen-dependent, despite lack of robust data, and thus only progesterone or progestin might be potentially used. It is possible that, in future, better molecular characterization of genomic profiles of various cancers may allow MHT to be used with some patients.

Menopausal symptoms in epithelial ovarian cancer survivors: a GINECO VIVROVAIRE2 study.

OBJECTIVE: We have previously shown that epithelial ovarian cancer (EOC) and its treatments have negative effects on long-term quality of life (QoL) and fatigue. The present multicenter study investigated the main menopausal symptoms and gynecological management of EOC survivors (EOCS). METHODS: 166 patients with relapse-free ≥3 years after the end of treatment attended a consultation with a gynecologist, including a questionnaire related to vasomotor symptoms (VMS) and sexuality, a clinical examination, a blood sample and an osteodensitometry. QoL, fatigue, insomnia and mood disorders were measured with validated questionnaires and correlated to VMS. VMS and QoL were assessed according to natural menopause (NM) or surgical menopause (SM). RESULTS: Mean age at the survey was 62 [21-83] years and stage III/IV (48%). Mean delay since the end of treatment was 6 years. Fifty-nine patients (36%) had SM. Half of patients reported VMS. Seventy-two percent of EOCS with SM had VMS compared to 41% with NM (P < .001). VMS were not associated with poor global QoL, fatigue, insomnia or mood disorders. Two-thirds of EOCS reported a decrease in libido. Patients with SM showed a greater decrease in libido than NM (P < .02). Fourteen percent of them had osteoporosis and 50% osteopenia. Among the 85 patients with VMS, 80 did not receive HRT after cancer treatment. At the time of the survey, only 7 (4%) patients were receiving hormone replacement therapy (HRT). CONCLUSIONS: VMS and sexual disorders are frequently reported by EOCS, particularly among patients with SM. Most EOCS with menopausal symptoms could benefit from HRT to improve these symptoms.

Systemic lupus erythematosus and menopause.

Estrogen has been known for a long time to be a trigger on auto-immunity and may influence the course of lupus. Women experiencing systemic lupus are at high risk for premature ovarian insufficiency if using cyclophosphamide, of osteoporosis, arterial ischemic diseases and venous thrombosis at young age. In about 30% of them, an antiphospholipid/anticoagulant antibody can occur which is associated with very high risk of thrombosis. However, the severity of the disease may vary and some women with lupus could benefit from a menopausal hormone therapy (MHT). As a consequence, management of menopause symptoms needs to evaluate carefully the condition of the patient, her lupus history and cardiovascular risk. We will describe the effect of lupus on menopause, of menopause on lupus and report in detail the literature available on MHT and the risk of lupus or the risk of flares in women with lupus. Some other options than MHT for the management of climacteric symptoms will be discussed.

Long-term fatigue and quality of life among epithelial ovarian cancer survivors: a GINECO case/control VIVROVAIRE I study.

BACKGROUND: Few data are available on long-term fatigue (LTF) and quality of life (QoL) among epithelial ovarian cancer survivors (EOCS). In this case-control study, we compared LTF, symptoms and several QoL domains in EOCS relapse-free ≥3 years after first-line treatment and age-matched healthy women. PATIENTS AND METHODS: EOCS were recruited from 25 cooperative GINECO centers in France. Controls were randomly selected from the electoral rolls. All participants completed validated self-reported questionnaires: fatigue (FACIT-F), QoL (FACT-G/O), neurotoxicity (FACT-Ntx), anxiety/depression (HADS), sleep disturbance (ISI), and physical activity (IPAQ). Severe LTF (SLTF) was defined as a FACIT-F score <37/52. Univariate and multivariate logistic regressions were conducted to analyze SLTF and its influencing factors in EOCS. RESULTS: A total of 318 EOCS and 318 controls were included. EOCS were 63-year-old on average, with FIGO stage I/II (50%), III/IV (48%); 99% had received platinum and taxane chemotherapy, with an average 6-year follow-up. There were no differences between the two groups in socio-demographic characteristics and global QoL. EOCS had poorer FACIT-F scores (40 versus 45, P < 0.0001), lower functional well-being scores (18 versus 20, P = 0.0002), poorer FACT-O scores (31 versus 34 P < 0.0001), and poorer FACT-Ntx scores (35 versus 39, P < 0.0001). They also reported more SLTF (26% versus 13%, P = 0.0004), poorer sleep quality (63% versus 47%, P = 0.0003), and more depression (22% versus 13%, P = 0.01). Fewer than 20% of EOCS and controls exercised regularly. In multivariate analyses, EOCS with high levels of depression, neurotoxicity, and sleep disturbance had an increased risk of developing SLTF (P < 0.01). CONCLUSION: Compared with controls, EOCS presented similar QoL but persistent LTF, EOC-related symptoms, neurotoxicity, depression, and sleep disturbance. Depression, neuropathy, and sleep disturbance are the main conditions associated with severe LTF.

Progesterone, progestins and the breast in menopause treatment.

Breast cancer is the main risk associated with menopause hormone therapy (MHT). It is a hormone-dependent cancer. In postmenopausal women, about 80% of cases are estradiol receptor-positive. In cohort studies only estradiol receptor-positive breast cancers are promoted by MHT. Different levels of risk with estrogen-only treatment and combined treatment with estrogen + progestin are shown in randomized trials and observational studies. Several non-randomized studies show a lower risk with progesterone and retroprogesterone than with synthetic progestins. Progesterone and progestin are non-selective ligands for the progesterone receptor and bind also with other steroid receptors, with agonistic or antagonistic effects according to the structure of the molecule. Their half-life and metabolism are also different, progesterone being rapidly degraded with a short half-life. These aspects will be discussed in this review.

Migraine, hormones and the menopausal transition.

Migraine is a common, disabling and incapacitating headache disorder that may be triggered by many factors, such as hormones especially during the perimenopausal period, where large alterations in estradiol levels can occur. The evidence implies that hormonal fluctuations are one of the important triggers of migraine. During reproductive life and during hormonal contraception, the course of migraine can be impacted. Different types of migraine with and without aura can be variously influenced by hormones. Migraine can constitute a risk factor for stroke and this must be taken in account for menopause hormone therapy. Hormone therapy is a possible approach to prevent migraine that happens during the menopause transition. Scarce data on the various regimens and types of hormone therapy are available. Transdermal estradiol displays a more favorable profile on migraine than oral estrogens because it may provide more constant levels of estrogens.

Progesterone, progestins and the endometrium in perimenopause and in menopausal hormone therapy.

It is well established that unopposed estrogen for hormone therapy in postmenopausal women (MHT) induces a dose-related stimulation of the endometrium associated with an increased risk of hyperplasia and endometrial cancer. Progesterone acts physiologically to counteract the proliferative effects of estradiol during the menstrual cycle. In MHT, progestogens protect the endometrium against the proliferative effects of estrogens in women with a uterus. Recent data suggest that, whereas micronized progesterone is apparently safer for the breast, it could be less efficient than synthetic progestin on the endometrium. An update on progestogen and endometrial safety in MHT is the subject of this review.

Hereditary angioedema with normal C1 inhibitor and factor XII mutation: a series of 57 patients from the French National Center of Reference for Angioedema.

Hereditary angioedema (HAE) is a rare disease associated with either a quantitative or qualitative deficiency in C1-inhibitor (C1-INH) or normal C1-INH. HAE with normal C1-INH is associated in 20% of cases with mutations in the gene for factor XII (FXII) or FXII-HAE. A recent review described 41 families, including 14 German and 15 Spanish families. We have constructed a register of French patients and their characteristics. A national survey was launched through the French National Center of Reference for Angioedema (CREAK) to study the clinical, biological and therapeutic characteristics of patients with HAE linked to a mutation of FXII gene. Fifty-seven patients were identified from 24 different families. In most cases they were young women (mean age at diagnosis: 31 years, mean age at first symptom: 21 years, female/male ratio: 76%). Twenty-one per cent of the patients experienced angioedema attacks only during pregnancy or when on oestrogen contraception. Sixty-three per cent had attacks at all times, but they were more severe during these same periods. Male carriers of the mutation were more frequently asymptomatic than females (P = 0·003). C1-INH concentrate and icatibant were both effective for treating attacks. The prophylactic use of tranexamic acid led to a 64% decrease in the number of attacks. This is one of the largest series reported of HAE patients with FXII mutation. The therapeutic management appeared to be identical to that of HAE with C1-INH deficiency.

Deletion of CPEB1 Gene: A Rare but Recurrent Cause of Premature Ovarian Insufficiency.

CONTEXT: Premature ovarian insufficiency (POI) may be secondary to chemotherapy, radiotherapy, or environmental factors. Genetic causes are identified in 20-25% of cases, but most POI cases remain idiopathic. OBJECTIVE: This study aimed to identify new genes involved in POI and to characterize the implication of CPEB1 gene in POI. DESIGN AND SETTING: This was a case report and cohort study replicate conducted in academic medical centers. PATIENTS AND METHODS: A deletion including CPEB1 gene was first identified in a patient with primary amenorrhea. Secondly, 191 sporadic POI cases and 68 familial POI cases were included. For each patient, karyotype was normal and FMR1 premutation was excluded. Search for CPEB1 deletions was performed by quantitative multiplex PCR of short fluorescent fragments or DNA microarray analysis. Gene sequencing of CPEB1 was performed for 95 patients. RESULTS: We identified three patients carrying a microdeletion in band 15q25.2. The proximal breakpoint, for the three patients, falls within a low-copy repeat region disrupting the CPEB1 gene, which represents a strong candidate gene for POI as it is known to be implicated in oocyte meiosis. No mutation was identified by sequencing CPEB1 gene. Therefore, heterozygous deletion of CPEB1 gene leading to haploinsufficiency could be responsible for POI in humans. CONCLUSION: Microdeletions of CPEB1 were identified in 1.3% of patients with POI, whereas no mutation was identified. This microdeletion is rare but recurrent as it is mediated by nonallelic homologous recombination due to the existence of low-copy repeats in the region. This result demonstrates the importance of DNA microarray analysis in etiological evaluation and counseling of patients with POI.

Chronic urticaria and hormones: Is there a link?

BACKGROUND: While the role of oestrogens in bradykinin angioedema (AE) has been clearly demonstrated, scarce data are available about the role of sex hormones in chronic urticaria (CU). OBJECTIVES: To gather information from a population of women with various forms of CU [chronic spontaneous urticaria (CSU), including a subtype of isolated histaminic AE and a classic subtype of association of wheals and AE, and exclusive inducible urticaria (IU)] about the impact of sex hormones and reproductive factors on their symptoms. METHODS: This was a cross-sectional study comprising interviews of 200 women consulting for CU at nine centres throughout France between May and July 2013. The dermatologists filled in an online questionnaire on the impact of reproductive factors (puberty, contraception and pregnancy) and hormonal treatments on the course of CU, including CSU and IU, in the presence of the women. RESULTS: Most of the women did not experience CU before puberty and if so, puberty did not influence the course of CU. Only 16 women had experienced a pregnancy during CU which caused a worsening of symptoms in four. Hormonal contraception was associated with aggravation in a minority of women, mostly women with CSU (10%). Women with isolated histaminic AE did not exhibit any female sex hormone dependency. CONCLUSIONS: It would appear that sex hormones act as a trigger in only a small subset of women with CU. Nevertheless, this should be taken into account to improve patient management.

Treatment of symptoms of the menopause: an Endocrine Society Clinical Practice Guideline

OBJECTIVE: The objective of this document is to generate a practice guideline for the management and treatment of symptoms of the menopause. PARTICIPANTS: The Treatment of Symptoms of the Menopause Task Force included six experts, a methodologist, and a medical writer, all appointed by The Endocrine Society. EVIDENCE: The Task Force developed this evidenced-based guideline using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system to describe the strength of recommendations and the quality of evidence. The Task Force commissioned three systematic reviews of published data and considered several other existing meta-analyses and trials. CONSENSUS PROCESS: Multiple e-mail communications, conference calls, and one face-to-face meeting determined consensus. Committees of The Endocrine Society, representatives from endorsing societies, and members of The Endocrine Society reviewed and commented on the drafts of the guidelines. The Australasian Menopause Society, the British Menopause Society, European Menopause and Andropause Society, the European Society of Endocrinology, and the International Menopause Society (co-sponsors of the guideline) reviewed and commented on the draft. CONCLUSIONS: Menopausal hormone therapy (MHT) is the most effective treatment for vasomotor symptoms and other symptoms of the climacteric. Benefits may exceed risks for the majority of symptomatic postmenopausal women who are under age 60 or under 10 years since the onset of menopause. Health care professionals should individualize therapy based on clinical factors and patient preference. They should screen women before initiating MHT for cardiovascular and breast cancer risk and recommend the most appropriate therapy depending on risk/benefit considerations. Current evidence does not justify the use of MHT to prevent coronary heart disease, breast cancer, or dementia. Other options are available for those with vasomotor symptoms who prefer not to use MHT or who have contraindications because these patients should not use MHT. Low-dose vaginal estrogen and ospemifene provide effective therapy for the genitourinary syndrome of menopause, and vaginal moisturizers and lubricants are available for those not choosing hormonal therapy. All postmenopausal women should embrace appropriate lifestyle measures.

A Commentary on a recent update of the ovarian cancer risk attributable to menopausal hormone therapy.

The incidence of ovarian cancer is tenfold lower than that of breast cancer. The goal of the recently published meta-analysis by Beral and colleagues, using 'individual participant datasets from 52 epidemiological studies', was to provide an updated assessment of the effect of menopausal hormone therapy (MHT) on ovarian cancer risk. The relative risk generated from the cited prospective studies was significantly increased but the relative risk from the retrospective studies was not. This is quite unusual since retrospective studies usually display higher levels of relative risk. No further increase was observed with increasing duration. Moreover, a number of the studies could not be adjusted for important ovarian cancer risk factors. From the meta-analysis, it can be calculated that the absolute excess risk of 5 years of MHT for a 50-year-old UK woman is 1 in 10 000 per year, indicating a very low risk. We conclude that this meta-analysis mostly reflects the previously published data from the Million Women Study, from which the majority of this new publication is derived.

Estetrol is a weak estrogen antagonizing estradiol-dependent mammary gland proliferation.

Estetrol (E4) is a natural estrogen produced exclusively by the human fetal liver during pregnancy. Its physiological activity remains unknown. In contrast to ethinyl estradiol and estradiol (E2), E4 has a minimal impact on liver cell activity and could provide a better safety profile in contraception or hormone therapy. The aim of this study was to delineate if E4 exhibits an activity profile distinct from that of E2 on mammary gland. Compared with E2, E4 acted as a low-affinity estrogen in both human in vitro and murine in vivo models. E4 was 100 times less potent than E2 to stimulate the proliferation of human breast epithelial (HBE) cells and murine mammary gland in vitro and in vivo respectively. This effect was prevented by fulvestrant and tamoxifen, supporting the notion that ERα (ESR1) is the main mediator of the estrogenic effect of E4 on the breast. Interestingly, when E4 was administered along with E2, it significantly antagonized the strong stimulatory effect of E2 on HBE cell proliferation and on the growth of mammary ducts. This study characterizes for the first time the impact of E4 on mammary gland. Our results highlight that E4 is less potent than E2 and exhibits antagonistic properties toward the proliferative effect of E2 on breast epithelial cells. These data support E4 as a potential new estrogen for clinical use with a reduced impact on breast proliferation.

[Evaluation of theoretical teaching of the French diploma of medical gynecology]. / Enseignement théorique du Diplôme d'études spécialisées de gynécologie médicale en France: évaluation nationale.

OBJECTIVES: As far as the reform of the "Diplômes d'études spécialisées" (DES) is approaching, a first national evaluation of the Medical Gynecology diploma was necessary. The objective was to evaluate the practices of the theoretical teaching with the whole students, by receiving their opinions and their wishes of changing, and by proposing some improving measures. PATIENTS AND METHODS: The self-evaluation form made by members of the Association of residents (AIGM) and the Teacher's College (CNEGM) was submitted to the students during the national teaching session of June 2014. RESULTS: Fifty-six results were gathered among 145 students enrolled at the DES (38.6 %). Twelve half days of national theoretical training are yearly scheduled. The accordance of the national theoretical training to the level of the students was assessed on average at 7.8 (VAS from 0 to 10). The scientific and pedagogical skills of the speakers are evaluated at 8.9 and 7.8. The theoretical training of the diploma was considered as satisfying for 76.6 % of the respondents. DISCUSSION AND CONCLUSION: Despite a globally satisfying evaluation, some points can be improved in the organization of the diploma. The introduction of courses about establishment, medical acts and imaging, the implementation of gradual progress teaching, the development of hands-on training and practical works, reciprocal evaluation of the students and the teachings/teachers, should be set up.

Chikungunya virus and West Nile virus infections imported into Belgium, 2007-2012.

Arboviral infections are emerging among tourists travelling to (sub)tropical regions. This study aims to describe the importation of chikungunya virus (CHIKV) and West Nile virus (WNV) into Belgium over a 6-year period from 2007 to 2012. Clinical samples were obtained from travellers presenting at the outpatient clinic of the Institute of Tropical Medicine (ITM), Antwerp, Belgium or submitted to the Central Laboratory for Clinical Biology of the ITM. Testing was performed by serology and/or by real-time reverse transcriptase-polymerase chain reaction. A total of 1288 returning travellers were investigated for CHIKV infection resulting in 34 confirmed and two probable diagnoses (2·80%). Out of 899 patients, four confirmed and one probable imported WNV infections were diagnosed (0·55%). No locally acquired cases have been registered in Belgium until now and the geographical origin of the imported infections reflects the global locations where the viruses are circulating.

Prevention of diseases after menopause.

Women may expect to spend more than a third of their lives after menopause. Beginning in the sixth decade, many chronic diseases will begin to emerge, which will affect both the quality and quantity of a woman's life. Thus, the onset of menopause heralds an opportunity for prevention strategies to improve the quality of life and enhance longevity. Obesity, metabolic syndrome and diabetes, cardiovascular disease, osteoporosis and osteoarthritis, cognitive decline, dementia and depression, and cancer are the major diseases of concern. Prevention strategies at menopause have to begin with screening and careful assessment for risk factors, which should also include molecular and genetic diagnostics, as these become available. Identification of certain risks will then allow directed therapy. Evidence-based prevention for the diseases noted above include lifestyle management, cessation of smoking, curtailing excessive alcohol consumption, a healthy diet and moderate exercise, as well as mentally stimulating activities. Although the most recent publications from the follow-up studies of the Women's Health Initiative do not recommend menopause hormonal therapy as a prevention strategy, these conclusions may not be fully valid for midlife women, on the basis of the existing data. For healthy women aged 50-59 years, estrogen therapy decreases coronary heart disease and all-cause mortality; this interpretation is entirely consistent with results from other randomized, controlled trials and observational studies. Thus. as part of a comprehensive strategy to prevent chronic disease after menopause, menopausal hormone therapy, particularly estrogen therapy may be considered as part of the armamentarium.

Tranexamic acid as maintenance treatment for non-histaminergic angioedema: analysis of efficacy and safety in 37 patients.

Angioedema (AE) is a clinical syndrome characterized by localised swelling lasting several hours. The swelling is often recurring and can be lethal if it is located in the laryngeal region. Much progress has been made recently in the treatment of acute episodes, but no consensus has been reached on maintenance treatment. We have performed a national retrospective observational study to assess the use of tranexamic acid (TA) as maintenance treatment for non-histaminergic AE [hereditary AE (HAE) or idiopathic non-histaminergic AE]. Records for 64 cases were collected from 1 October 2012 to 31 August 2013; 37 of these were included (12 HAE with C1-inhibitor deficiency, six with HAE with normal C1-inhibitor and 19 idiopathic non-histaminergic AE). When treated with TA over six months, the number of attacks was reduced by 75% in 17 patients, 10 patients showed a lower level of reduction and 10 had the same number of attacks. In no instances were symptoms increased. No thromboembolic events were observed, and the main side effects were digestive in nature. Thus, TA, which is well tolerated and inexpensive, appears to be an effective maintenance treatment for some patients with HAE or idiopathic non-histaminergic AE.

Should women suffering from migraine with aura be screened for biological thrombophilia?: results from a cross-sectional French study.

INTRODUCTION: Migraine, particularly migraine with aura (MA), is associated with a higher risk for ischemic stroke (IS). A procoagulant state may predispose to IS. Whether inherited biological thrombophilia are associated with migraine risk remains controversial. OBJECTIVE: To assess the risk of migraine without or with aura related to inherited biological thrombophilia adjusted for the main potential confounders. MATERIAL AND METHODS: A cross-sectional study was conducted in 1456 French women aged 18 to 56years, referred for biological coagulation check-up because of personal or familial venous thrombosis history. Between April 2007 and December 2008, all women answered a self-administered questionnaire to determine whether they had headache. RESULTS: There were 294 (20%) migrainous sufferers (including 71 [5%] with MA), 975 (67%) non migrainous women and 187 (13%) non migrainous headache women. Inherited thrombophilia were detected in 576 (40%) women, including 389 (40%) non migrainous women, 90 (40%) migraine without aura (MWA), 33 (46%) MA women and 64 (34%) non migrainous headache women. Factor V Leiden (FVL) i.e. F5rs6025 or Factor II G20210A (FIIL) i.e. F2rs1799963 mutation was detected in 296 (30%) non migrainous women and in 100 (34%) migrainous women of which 27 had MA. There was a significant association between MA and FVL or FIIL mutations (adjusted OR=1.76 [95% CI 1.02-3.06] p=0.04) whereas this association in MWA and in non migrainous headache women was not significant. There was no significant association between migraine and other biological thrombophilia. CONCLUSION: FVL or FIIL mutations were more likely among patients suffering from MA. Whether biological thrombophilia screening should be systematically performed in women suffering from MA remains to be determined.
