Reproductive BioMedicine Online (RBMO) Partnership

Reproductive BioMedicine Online (RBMO) is delighted to welcome the World Endometriosis Society (WES) as a new Affiliated Society of the journal.

The World Endometriosis Society is a global organisation with a mission to advance evidence-based standards and innovations for education, advocacy, clinical care, and research in endometriosis, adenomyosis, and related disorders.

RBMO is proud to collaborate with WES, to provide an international platform for the research, innovative thought and activities of its members, in pursuit of a shared goal to further the management, classification, diagnosis, and ultimately the prevention of endometriosis.

RBMO Co-Chief Editor Prof. Juan García-Velasco says of the new partnership “We at RBMO are very enthusiastic about the potential to work together with WES and their members. The impact of endometriosis and adenomyosis on reproduction, general health, and wellbeing across women’s lives are still a matter of investigation, with best clinical approaches advancing and evolving. RBMO will provide a strong platform for these papers to be published and discussed among colleagues working with the same focus.”

WES President, Prof. Stacey Missmer comments “WES leadership and our members are excited to partner with RBMO to continue our mission of encouraging novel and impactful discoveries and disseminating their findings to raise knowledge, awareness, and attention for maximum benefit to all who are impacted by endometriosis or adenomyosis.”

RBMO Co-Chief Editor Prof. Nick Macklon says: “We very much look forward to establishing our relationship with WES and working together to highlight the Societies’ reproductive health initiatives and publications.”

Together with journal publisher Elsevier, Reproductive BioMedicine Online and the World Endometriosis Society look forward to expanding the opportunities to support Society members and authors in improving the quality of life of endometriosis patients.

Introduction:
Endometriosis is characterized by endometrial-type glands and stroma growing outside of the uterine cavity, evading the typical cell-intrinsic and cell-extrinsic safeguards (including immune surveillance) that should prevent cells from surviving at ectopic locations. Chronic inflammation and dysregulation in the immune response contribute to the pathogenesis of endometriosis, however, little is understood regarding how immune dysregulation contributes to the extensive heterogeneity that characterizes endometriosis.

Aim:
This research seeks to phenotype the immune repertoire in endometriosis and explore the dysregulation in the molecular signals in the tissue microenvironment that influences immune cell recruitment and function.

Materials and Methods:
Single cell RNA sequencing was applied to >370,000 cells from endometriosis, eutopic endometrium, unaffected ovary and endometriosis-free peritoneum. All specimens were subjected to pathology review and genotyping for somatic variants in commonly mutated genes.

Results:
Endometriosis patients could be stratified into ‘immune-hot’ or ‘immune-cold’ subgroups based on the presence of lymphoid aggregates and germinal centers proximal to lesions. B-cells and plasma cells were particularly enriched in endometriosis. Elevated autoreactive antibodies, B-cell survival and recruitments signals and an interferon signature are seen in endometriosis.

Conclusion and impact:
Extensive heterogeneity in immune responses to endometriosis may explain, at least in part, the heterogenous presentations and symptoms associated with disease. Ongoing experiments are exploring the therapeutic potential of the anti-CD20 monoclonal antibody for patients with elevated B-cell dysfunction. This research is providing clinically relevant insights into the role of B-cells in the pathogenesis of endometriosis and potential targets for both diagnosis and therapeutics.

Rodolphe Maheux Award 2023 presented to Scott MacKenzie

The 2023 Rodolphe Maheux Award for best Clinical Abstract was presented to Scott MacKenzie at the closing ceremony of the 15th World Congress on Endometriosis for his work on how Genome-wide association reveals a locus in Neuregulin 3 associated with gabapentin efficacy in women with chronic pelvic pain.

Introduction:
Chronic pelvic pain (CPP) in women with no obvious pelvic pathology has few evidence-based treatment options. Our recent multicentre randomised controlled trial (GaPP2) in women with CPP showed that gabapentin did not relieve pain and was associated with higher rates of side-effects than placebo. However, the data suggest that subgroups of women could benefit from gabapentin.

Aim:
To identify if common genetic variants are associated with gabapentin response in women with CPP with no obvious pelvic pathology.

Materials and Methods:
We conducted a genome-wide association study of gabapentin response, using participants from GaPP2. Two phenotypes were investigated: gabapentin analgesic response (≥30% reduction in worst and/or average pain), and side-effect burden (≥3 side-effects reported). Standard genetic quality control was conducted followed by imputation to HRC reference panel. Frequentist association analysis was conducted in SNPTEST including autosomes and chromosome X.

Results:
93 participants provided salivary samples for genotyping (82 passed quality control) and 5,522,729 SNPs were tested for association (n=29 ≥30% vs. n=42 <30% reduction in worst and/or average pain scores). One genome-wide significant association with gabapentin analgesic response was identified, rs4442490, an intron variant located in Neuregulin 3 (NRG3) at 10q23.1 (p=2.11×10−8; OR=18.82 (95%CI 4.86–72.83);
MAF=0.42). NRG3 is expressed predominantly in brain tissues and involved in nervous system maintenance/repair. No SNPs reached genome-wide significance for gabapentin side-effect burden.

Conclusion and impact:
A locus in NRG3 is associated with gabapentin efficacy in women with CPP with no obvious pelvic pathology, highlighting the possibility of a precision medicine approach to symptom management.

15th World Congress on Endometriosis, 2023

Registration during the opening day of the congress; the excitement was palpable. Over 1100 delegates from over 50 countries attended this brilliant congress, all with a common goal of improving endometriosis care for those living with the condition.

Dr Mathew Leonardi, Assistant Professor in Obstetrics & Gynaecology from McMaster University chaired the incredibly well attended pre-congress meeting in diagnosing and staging endometriosis with ultrasound. His clear message of “Diagnosis is therapy” was present throughout the full conference.

Below, the amazing Alison Deslandes, Specialist Obstetrics and Gynaecological sonographer from the University of Adelaide, scanning our volunteer patient. A live, in-real time ultrasound scan demonstrating the importance of diagnosis of endometriosis to allow those living with the condition feel more empowered about their care.

The art exhibition offered a very thought-provoking visual representation of endometriosis, the condition affecting 1 in 10 women and those assigned female at birth (of reproductive age).

EXPPECT PhD student Katherine Edgley presenting her 2 posters at the congress. One on high adherence to using smartwatches in combination with daily self-reports in patients with endometriosis.

The other, on managing pain and fatigue in endometriosis by exploring the role of physical activity, sleep and diurnal rhythms through smartwatch data.

World Congress on Endometriosis provided a fantastic networking opportunity for the clinicians of the future. Below we see 5th year University of Edinburgh medical student Kevin Kuan who has an interest in endometriosis care and was able to have the opportunity to present 2 posters, outlining his research into improving outcomes for those living with endometriosis.

World congress was a mammoth team effort including volunteers from all backgrounds who wanted to help at such a pivotal event for those suffering from endometriosis and clinicians wishing to improve endometriosis-related care. Below we have Ann Doust, Research Portfolio Manager to Professor Andrew Horne; the excitement did not dwindle as the week progressed.

Professors Philippa Saunders, Andrew Horne and Luk Rombauts giving a true Scottish welcome to delegates attending the conference.

A group of dedicated endometriosis specialists took on the huge challenge of cycling from Endometriosis UKs headquarters in London all the way to Edinburgh to attend the World Congress on Endometriosis, raising an incredible £10,835 in the process.

Professor John Cryan from University College Cork gave an amazing keynote on the gut brain axis. “An evidence base for the role of the gut microbiome in endometriosis is poised to change the way we understand & treat it. Unlike the genome, the microbiome is modifiable”.

The audience was captivated during one of the many talks given in the main auditorium.

Specialist Research Nurse Priscilla Fernandez from University of Edinburgh presented on the important topic of the Nurse Specialist role in research highlighting the importance of multidisciplinary team working and how it benefits patients seeking new treatment options.

Dr Lucy Whitaker Clinical Lecturer in Obstetrics & Gynaecology from University of Edinburgh presented on an exploratory open label study (EPiC1) of Dichloroacetate (DCA) to treat endometriosis associated pain. EPiC2 to start recruitment during the autumn of 2023.

The main auditorium, full of delegates from different disciplines, with one common objective of helping those with endometriosis.

Reframing Endometriosis: Power, Politics and Potential Futures


British Academy/Wellcome Trust Conferences bring together scholars and specialists from around the world to explore themes related to health and wellbeing.

Endometriosis is a common yet poorly understood condition. Media and academic discourse often highlight failures in diagnosis as emblematic of gender biases in health. This conference focuses on practices of exclusion in past and present approaches to endometriosis as well as potential inclusive futures.

It is the first academic conference to bring together UK and internationally based endometriosis social science and humanities researchers alongside, and in conversation with, prominent (bio)medical researchers, third sector representatives and independent researchers and authors.

The way endometriosis is categorised is central to how it is understood and experienced. Speakers will discuss the historical legacies of endometriosis as a ‘wandering womb’ induced ‘hysteria’ and ‘career women’s disease’. They will consider intersecting systems of power and the marginalisation of gendered, racialised, and disabled bodies. And they will explore the socio-cultural-political implications of the latest medical research suggesting endometriosis is a systemic (whole body), rather than a solely gynaecological, disease.

For Registration and more information, see the conference website: Reframing Endometriosis: Power, Politics and Potential Futures | The British Academy
