A picture of medically assisted reproduction activities during the COVID-19 pandemic in Europe

STUDY QUESTION: How did coronavirus disease 2019 (COVID-19) impact on medically assisted reproduction (MAR) services in Europe during the COVID-19 pandemic (March to May 2020)? SUMMARY ANSWER: MAR services, and hence treatments for infertile couples, were stopped in most European countries for a mean of 7 weeks. WHAT IS KNOWN ALREADY: With the outbreak of COVID-19 in Europe, non-urgent medical care was reduced by local authorities to preserve health resources and maintain social distancing. Furthermore, ESHRE and other societies recommended to postpone ART pregnancies as of 14 March 2020. STUDY DESIGN, SIZE, DURATION: A structured questionnaire was distributed in April among the ESHRE Committee of National Representatives, followed by further information collection through email. PARTICIPANTS/MATERIALS, SETTING, METHODS: The information was collected through the questionnaire and afterwards summarised and aligned with data from the European Centre for Disease Control on the number of COVID-19 cases per country. MAIN RESULTS AND THE ROLE OF CHANCE: By aligning the data for each country with respective epidemiological data, we show a large variation in the time and the phase in the epidemic in the curve when MAR/ART treatments were suspended and restarted. Similarly, the duration of interruption varied. Fertility preservation treatments and patient supportive care for patients remained available during the pandemic. LARGE SCALE DATA: N/A. LIMITATIONS, REASONS FOR CAUTION: Data collection was prone to misinterpretation of the questions and replies, and required further follow-up to check the accuracy. Some representatives reported that they, themselves, were not always aware of the situation throughout the country or reported difficulties with providing single generalised replies, for instance when there were regional differences within their country. WIDER IMPLICATIONS OF THE FINDINGS: The current article provides a basis for further research of the different strategies developed in response to the COVID-19 crisis. Such conclusions will be invaluable for health authorities and healthcare professionals with respect to future similar situations.peer-reviewe

Cell signalling and serum marker of cell proliferation in adenomyosis

L’adénomyose est une pathologie chronique bénigne de l’utérus caractérisée par une infiltration du myomètre par du tissu endométrial composé de glandes et de stroma avec une hypertrophie et une hyperplasie des cellules musculaires lisses adjacentes. Cette maladie fréquente de la femme en âge de procréer cause des symptômes invalidants comme des dysménorrhées, des saignements utérins anormaux et une infertilité. L’adénomyose utérine est souvent associée à d’autres pathologies gynécologiques bénignes œstrogéno-dépendantes comme les léiomyomes utérins et l’endométriose. Les options thérapeutiques médicamenteuses sont purement symptomatiques et non-curatives et l’adénomyose reste une cause majeure d’hystérectomie. Les mécanismes physiopathologiques qui aboutissent au développement de l’adénomyose sont probablement multifactoriels et ne sont que partiellement compris actuellement. Selon la théorie la plus communément admise, l’adénomyose trouve son origine dans la couche basale de l’endomètre avec une invagination de cellules entre les faisceaux musculaires et/ou le long de vaisseaux lymphatiques. De multiples facteurs pourraient être impliqués dans l’initiation de cette invasion, notamment une résistance à l’action de la progestérone, une production intra-lésionnelle d’œstrogènes par activation de l’aromatase, des anomalies myométriales prédisposant à l’invasion, des lésions tissulaires induites par la grossesse, l’accouchement, le dyspéristaltisme utérin ou iatrogènes et des anomalies de l’endomètre le prédisposant à l’invasion. Dans un premier temps nous détaillons, dans un article de revue, les traitements médicamenteux actuellement utilisés pour traiter les symptômes causés par l’adénomyose et discutons les mécanismes physiopathologiques qui pourraient être la cible de nouveaux traitements médicamenteux. Ensuite, nous exposons les résultats de l’étude in vitro des voies de signalisation cellulaires des mitogen-activated protein kinases (MAPKs) et phosphatidylinositol 3 kinase/Akt/mammalian target of rapamycin (PI3K/mTOR/Akt) dans les cellules musculaires lisses utérines issues de femmes avec de l’adénomyose et de témoins sans adénomyose. Nous montrons une augmentation de la prolifération des cellules myométriales avec une activation in vitro de la voie MAPK/ERK chez les femmes avec de l’adénomyose en comparaison avec les témoins. L’activation de la voie PI3K/mTOR/Akt n’est pas significativement différente. La production de dérivés réactifs de l’oxygène et leurs voies de détoxification ne sont pas différentes dans les cellules myométriales de femmes avec de l’adénomyose et celles de témoins, ce qui suggère une activation de la voie des MAPK/ERK indépendante des dérivés réactifs de l’oxygène. Nos résultats montrent que des inhibiteurs des protéines kinases et le rapanalogue temsirolimus contrôlent la prolifération des cellules myométriales in vitro, ce qui suggère une implication des voies de signalisation MAPK/ERK et PI3K/mTOR/Akt dans la prolifération des cellules musculaires lisses dans l’adénomyose et les léiomyomes. Finalement, nous avons étudié l’ostéopontine comme biomarqueur sérique dans une cohorte de femmes en âge de procréer opérées pour des pathologies gynécologiques bénignes. La présence d’endométriose a été déterminée chirurgicalement et les lésions endométriosiques ont été confirmées histologiquement et classées en lésions superficielles, endométriomes ou lésions invasives profondes. La présence d’adénomyose a été déterminée par imagerie par résonance magnétique préopératoire et deux types d’adénomyose ont été caractérisés : l’adénomyose diffuse, l’adénomyose focale avec ou sans lésions diffuses associées. L’ostéopontine sérique est diminuée en cas d’adénomyose focale et de lésions d’endométriose profonde en comparaison avec des témoins sains et augmentée dans l’endométriose superficielle en comparaison avec l’endométriose profonde. (...)Adenomyosis is chronic benign uterine disease characterized by myometrial infiltration by endometrial tissue – both glands and stroma – with hypertrophy and hyperplasia of surrounding smooth muscle cells. This frequent disease occurring in reproductive age women causes invalidating symptoms such as dysmenorrhoea, abnormal uterine bleeding and infertility. Adenomyosis is frequently associated with other estrogen-dependant gynaecologic diseases such as uterine leiomyomas and endometriosis. Medical treatments are non-curative and act purely by alleviating symptoms and adenomyosis remains a major cause of hysterectomy. Physiopathological mechanisms underlying the disease are probably multifactorial and currently not fully elucidated. According to the most widely accepted theory adenomyosis originates from the basal layer of the endometrium which invaginates between smooth muscle cell bundles and/or along lymphatic vessels. Multiple factors could be implicated in triggering this invasion, amongst others resistance to progesterone, intra-lesional production of estrogens through aromatase activation, myometrial anomalies predisposing to invasion, tissue lesions induced by pregnancy, labour, uterine dysperistaltism or iatrogenic and endometrial anomalies predisposing to invasion. First, in a clinical review article, we detail current medical therapies used to alleviate adenomyosis-associated symptoms and discuss physiopathological mechanisms that could be targets for novel medical treatments. We then describe an in vitro study on the activation of the mitogen-activated protein kinases (MAPKs) and phosphatidylinositol three kinase/mammalian target of rapamycin/Akt (PI3K/mTOR/Akt) signalling pathways in uterine smooth muscle cells derived from women with adenomyosis and from adenomyosis-free controls. We show an increased proliferation of uterine smooth muscle cells related to the in vitro activation of the MAPK/ERK pathway in women with adenomyosis compared to controls. The activation of PI3K/mTOR/Akt was not significantly different. The production of reactive oxygen species and their detoxification enzymes were not different in uterine smooth muscle cells of women with adenomyosis compared to controls suggesting a reactive oxygen species independent activation of the MAPK/ERK pathway. Our results also show that inhibitors of protein kinases and the rapanalogue temsirolimus control the in vitro proliferation of uterine smooth muscle cells suggesting an implication of both MAPK/ERK and PI3K/mTOR/Akt in the proliferation of uterine smooth muscle cells in adenomyosis and leiomyomas. Finally, we studied osteopontin as a serum biomarker in a cohort of reproductive-age women undergoing surgery for benign gynaecological conditions. The presence of endometriosis was determined surgically and endometriosis lesions were confirmed histologically and classified into superficial lesions, endometriomas and deep infiltrating lesions. The presence of adenomyosis was determined by magnetic resonance imaging before surgery and women were classified according to two types of adenomyosis: diffuse adenomyosis, focal adenomyosis with or without associated diffuse lesions. Osteopontin levels were decreased in case of focal adenomyosis and deep infiltrating endometriosis compared to disease-free women and increased in superficial endometriosis compared to deep infiltrating endometriosis. Osteopontin, a secreted glycoprotein implicated in inflammation and in tumor-metastasis, is not a biomarker of disease severity in endometriosis and adenomyosis but could reflect events implicated in peritoneal dissemination of endometriosis lesions

Anti-Müllerian hormone level measurement in gynaecology: Myths and clinical utility

Anti-Müllerian hormone (AMH) is a glycoprotein implicated in the regulation of the pace of ovarian follicular recruitment and loss and follicle selection in adult females. AMH predicts the magnitude of the response to controlled ovarian stimulation for assisted reproductive techniques and is used to individualize treatments and avoid ovarian hyperstimulation syndrome. In contrast, AMH levels do not seem to be related to fecundability or time to pregnancy and do not predict the results intrauterine inseminations or natural cycle in vitro fertilisation. AMH fluctuates only in a minor way during the menstrual cycle allowing its measure without regard to the menstrual cycle phase. The impact of hormonal treatments such as the oral contraceptive pill is still debated. AMH levels can also be used to study the impact of medical treatments, surgical procedure or environmental factors on ovarian reserve

The role of preventive uterine artery occlusion during laparoscopic myomectomy: a review of the literature

Surgical myomectomy is currently regarded as the standard conservative treatment for patients who wish to preserve their fertility. However, it presents two main problems: the intra- and postoperative risk of bleeding and the risk of recurrence of leiomyomas. Preventive occlusion of uterine arteries was described during laparoscopic myomectomy as one of the procedures addressing these issues

Women's lived experience of endometriosis-related fertility issues.

ObjectiveThe aim of the present study is to conduct a qualitative investigation to provide a deeper understanding of women's views about endometriosis, fertility and their perception of reproductive options.MethodsSemi-structured interviews were conducted by two female psychiatrists, specialized in gynecology and obstetrical consultation-liaison psychiatry, trained in qualitative procedures, with experience in qualitative studies and in psychological support of women attending infertility consultations. No prior relationship with respondents was established before data collection. Interviews were tape-recorded and transcribed. Interviews lasted 45-75 minutes. The transcripts were then analysed using thematic content analysis.ResultsTwenty-nine women were contacted. Twelve agreed to an interview at the hospital's infertility clinic. Eleven women with diverse sociodemographic characteristics were included. The key findings of thematic content analysis can be grouped into four topics: (1) Diagnostic announcement and initial delay; (2) Negative perceptions of initial care: pre-diagnosis phase; (3) Struggle with endometriosis and its treatment; (4) Issues related to health problems, fertility and reproductive options.ConclusionOur analysis of the interviews corroborates the distressing impact of the trivialization of pain and the uncertainty of or the long quest for diagnosis. The findings also stress various associated issues, from the diagnostic delay to the low success rates of fertility treatments. This qualitative analysis contributes to better understand the accumulation of negative emotions within the illness trajectory and the poor dyadic adjustment within the couple

Innovations in classical hormonal targets for endometriosis

Endometriosis is a chronic disease of unknown etiology that affects approximately 10% of women in reproductive age. Several evidences show that endometriosis lesions are associated to hormonal imbalance, including estrogen synthesis, metabolism and responsiveness and progesterone resistance. These hormonal alterations influence the ability of endometrial cells to proliferate, migrate and to infiltrate the mesothelium, causing inflammation, pain and infertility. Hormonal imbalance in endometriosis represents also a target for treatment. We provide an overview on therapeutic strategies based on innovations of classical hormonal mechanisms involved in the development of endometriosis lesions. The development phase of new molecules targeting these pathways is also discussed. Endometriosis is a chronic disease involving young women and additional biological targets of estrogen and progesterone pharmacological manipulation (brain, bone and cardiovascular tissue) need to be carefully considered in order to improve and overcome current limits of long-term medical management of endometriosis
