Int J Mol Sci 2024; 25:6473. [PMID: 38928175 PMCID: PMC11203696 DOI: 10.3390/ijms25126473] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2024] [Revised: 05/29/2024] [Accepted: 06/05/2024] [Indexed: 06/28/2024] Open
Abstract
Endometriosis (EM), a chronic condition in endometrial tissue outside the uterus, affects around 10% of reproductive-age women, significantly affecting fertility. Its prevalence remains elusive due to the surgical confirmation needed for diagnosis. Manifesting with a range of symptoms, including dysmenorrhea, dyschezia, dysuria, dyspareunia, fatigue, and gastrointestinal discomfort, EM significantly impairs quality of life due to severe chronic pelvic pain (CPP). Psychological manifestations, notably depression and anxiety, frequently accompany the physical symptoms, with CPP serving as a key mediator. Pain stems from endometrial lesions, involving oxidative stress, neuroinflammation, angiogenesis, and sensitization processes. Microbial dysbiosis appears to be crucial in the inflammatory mechanisms underlying EM and associated CPP, as well as psychological symptoms. In this scenario, dietary interventions and nutritional supplements could help manage EM symptoms by targeting inflammation, oxidative stress, and the microbiome. Our manuscript starts by delving into the complex relationship between EM pain and psychological comorbidities. It subsequently addresses the emerging roles of the microbiome, inflammation, and oxidative stress as common links among these abovementioned conditions. Furthermore, the review explores how dietary and nutritional interventions may influence the composition and function of the microbiome, reduce inflammation and oxidative stress, alleviate pain, and potentially affect EM-associated psychological disorders.

Abstract
Endometriosis (EM) is a gynecological inflammatory disease often accompanied by stress, chronic pelvic pain (CPP), anxiety, and depression, leading to a diminished quality of life. This review aims to discuss the relationship between systemic and local inflammatory responses in the central nervous system (CNS), focusing on glial dysfunctions (astrocytes and microglia) as in critical brain regions involved in emotion, cognition, pain processing, anxiety, and depression. The review presents that EM is connected to increased levels of pro-inflammatory cytokines in the circulation. Additionally, chronic stress and CPP as stressors may contribute to the dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, depleting the production of inflammatory mediators in the circulatory system and the brain. The systemic cytokines cause blood-brain barrier (BBB) breakdown, activate microglia in the brain, and lead to neuroinflammation. Furthermore, CPP may induce neuronal morphological alterations in critical regions through central sensitization and the activation of glial cells. The activation of glial cells, particularly the polarization of microglia, leads to the activation of the NLRP3 inflammasome and the overproduction of inflammatory cytokines. These inflammatory cytokines interact with the signaling pathways involved in neural plasticity. Additionally, persistent inflammatory conditions in the brain lead to neuronal death, which is correlated with a reduced volume of key brain regions such as the hippocampus. This review highlights the involvement of glial cells in the pathogenesis of the mental comorbidities of EM (i.e., pain, anxiety, and depression) and to discuss potential therapeutic approaches for targeting the inflammation and activation of microglia in key brain regions.

Abstract
BACKGROUND Many studies have found an association between mood-disorder-related traits and endometriosis and adenomyosis. However, the cause-effect relationship remains unclear. AIMS We conducted Mendelian randomisation analyses to evaluate any causal relationship between mood disorders and endometriosis as well as different sites of endometriosis. METHOD Summary-level statistics for mood-disorder-related traits and endometriosis (8288 cases, 68 969 controls) in European populations were derived from large-scale data-sets of genome-wide association studies. A two-sample Mendelian randomisation was performed using the inverse-variance weighted and weight median methods. Further sensitivity analyses, including heterogeneity, pleiotropy and leave-one-out analyses, were conducted to test the consistency of the results. RESULTS Genetically determined mood swings (odds ratio = 2.557, 95% CI: 1.192-5.483, P = 0.016) and major depression (odds ratio = 1.233, 95% CI: 1.019-1.493, P = 0.031) were causally associated with an increased risk of endometriosis. Mood swings (odds ratio = 4.238, 95% CI: 1.194-15.048, P = 0.025) and major depression (odds ratio = 1.512, 95% CI: 1.052-2.173, P = 0.025) were also causally associated with the risk of adenomyosis. Sensitivity analyses confirmed the reliability of the results. CONCLUSIONS Our results suggest that mood-disorder-related traits increase the risk of endometriosis and adenomyosis. This study provides new insights into the potential pathogenesis of endometriosis and adenomyosis, and highlights the importance of preventing endometriosis and adenomyosis in patients with mood-disorder-related traits.

Abstract
Studies have shown that the occurrence and development of endometriosis are closely linked to long-term psychological stress. The specific contribution of chronic stress to the metabolic adaptations in patients with endometriosis is still unknown. Lesions were removed from ten endometriosis patients during an operation, and the participants were divided into two groups using a psychological questionnaire. An mRNA Human Gene Expression Microarray analysis was applied to compare the mRNA expression profiles between the chronic stress group and the control group. In addition, the reliability of the mRNA Human Gene Expression Microarray analysis was verified by using research on metabolites based on both the liquid chromatography (LC-MS/MS) technique and quantitative reverse transcription polymerase chain reaction (RT-PCR). A microarray analysis of significantly up-regulated, differentially expressed genes between the chronic stress and the control groups showed genes that were principally related to metabolism-related processes and immune-related processes, such as the immune response process, negative regulation of T cell proliferation, the leucine metabolic process, and the L-cysteine metabolic process (p < 0.05). LC-MS showed that the differential metabolites were primarily concerned with arginine and proline metabolism, D-glutamine and D-glutamate metabolism, aspartate metabolism, glycine, serine metabolism, and tyrosine metabolism (p < 0.05). The possibility of chronic stress blocks the endometriosis immune response through metabolic reprogramming. Chronic stress reduces the supply of energy substrates such as arginine and serine, down-regulates T immune cell activation, and affects the anti-tumor immune response, thereby promoting the migration and invasion of endometriosis lesions in patients with chronic stress.

Efficacy of an environmental enrichment intervention for endometriosis: a pilot study. Front Psychol 2023; 14:1225790. [PMID: 37885745 PMCID: PMC10598732 DOI: 10.3389/fpsyg.2023.1225790] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2023] [Accepted: 09/11/2023] [Indexed: 10/28/2023] Open
Abstract
Introduction We have previously shown that Environmental Enrichment (EE), a multi-modal psychosocial intervention consisting of increased social interaction, novelty, and open spaces, improved disease presentation, anxiety, and immune-related disturbances in the rat model of endometriosis. However, there is a knowledge gap regarding the effects of EE interventions in patients with this painful, inflammatory chronic disease. Aim To adapt and test the efficacy of an EE intervention on pelvic pain, mental health, perceived stress, quality of life, and systemic inflammation in endometriosis patients through a randomized clinical trial (RCT). Materials and methods A multidisciplinary team with expertise in physiology, neuroscience, psychology, and women's health adapted and implemented a two-arm RCT comparing an EE intervention with a wait-list control group. Six EE modules administered on alternate weeks were provided to patients in the intervention (N = 29); controls received education only. Survey data and biospecimens were collected at baseline, end-of-study, and 3-months post-intervention to assess pain (Brief Pain Inventory, BPI), endometriosis-related quality of life-QoL (Endometriosis Health Profile-30, EHP30), anxiety (Generalized Anxiety Disorder 7, GAD7), depression (Patient Health Questionnaire for Depression 8, PHQ8), pain catastrophizing (Pain Catastrophizing Score, PCS), stress (Perceived Stress Scale-14, PSS14), and saliva cortisol levels (AM, PM). Results Compared to the wait-list controls, participants in the EE intervention showed significantly decreased GAD-7 scores at the end of the intervention and 3-month follow-up. Depression, perceived stress, and QoL improved at the 3-month follow-up compared to baseline. While pain levels did not improve, they significantly correlated with anxiety, depression, QoL and pain catastrophizing scores. Conclusion This pilot RCT demonstrated significant improvements in anxiety and depressive symptoms, QoL, and perceived stress, supporting enriched environments as an integrative psychosocial intervention to be used as adjuvant to the standard of care for endometriosis pain.

Abstract
Women experience chronic pain more often than men with some pain conditions being specific to women while others are more prevalent in women. Prolactin, a neuropeptide hormone with higher serum levels in women, has recently been demonstrated in preclinical studies to sensitize nociceptive sensory neurons in a sexually dimorphic manner. Dysregulation of prolactin and prolactin receptors may be responsible for increased pain especially in female predominant conditions such as migraine, fibromyalgia, and pelvic pain. In this review, we focus on the role of prolactin in endometriosis, a condition characterized by pelvic pain and infertility that affects a large proportion of women during their reproductive age. We discuss the symptoms and pathology of endometriosis and discuss how different sources of prolactin secretion may contribute to this disease. We highlight our current understanding of prolactin-mediated mechanisms of nociceptor sensitization in females and how this mechanism may apply to endometriosis. Lastly, we report the results of a systematic review of clinical studies conducted by searching the PubMed and EMBASE databases to identify association between endometriosis and blood levels of prolactin. The results of this search strongly indicate that serum prolactin levels are increased in patients with endometriosis and support the possibility that high levels of prolactin may promote pelvic pain in these patients and increase vulnerability to other comorbid pain conditions likely by dysregulating prolactin receptor expression. Targeting of prolactin and prolactin receptors may improve management of pain associated with endometriosis.

Abstract
BACKGROUND Endometriosis is a complex disease that affects approximately 10% of women of childbearing age. It is characterized by the presence of endometrial-like tissue outside the uterus and often results in symptoms such as pelvic pain and infertility. This condition may disturb mental health and decrease both the mental and physical health related quality of life of women. The aim of this study was to assess the emotional state and the intimate relational aspect of life in Lebanese women living with endometriosis. METHODS This is a case-control study that included 317 women (65 participants with endometriosis and 252 controls (1:3 ratio)). Participants completed an online survey that included questions related to endometriosis, Sexual Satisfaction Scale for Women, Couple Satisfaction Index, Perceived Partner Responsiveness Scale and the Depression, Anxiety and Stress Scale. RESULTS A significantly higher mean sexual satisfaction score was found in women without endometriosis compared to those with endometriosis (90.83 vs. 83.42; p = 0.006). No significant difference was found in terms of couple satisfaction, depression, anxiety, stress, and perceived partner responsiveness between the two groups. Higher couple satisfaction (Beta = 1.30) and perceived partner responsiveness (Beta = 0.16) were significantly associated with higher sexual satisfaction, whereas higher depression (Beta=-1.70) and having endometriosis compared to not (Beta=-6.51) were significantly associated with lower sexual satisfaction. CONCLUSION This study validated the link between endometriosis and sexual satisfaction and invalidated the association between endometriosis and emotional state, as well as couple satisfaction and perceived partner responsiveness. Greater sexual satisfaction was, however, linked to greater perceived partner responsiveness and greater couple satisfaction, as well as decreased signs of depression, anxiety, and stress. More research is warranted to better understand how Lebanese women are coping with the disease and how clinicians may help them further.

Abstract
Introduction We have previously shown that Environmental Enrichment (EE)-consisting of social support, novelty, and open spaces-decreased disease progression and anxiety in a rat model of endometriosis. We developed a novel EE intervention to be tested in a pilot randomized clinical trial (RCT) in patients with endometriosis, a painful, stressful disease. Objective To translate and evaluate the feasibility and acceptability of an adapted EE intervention as an adjuvant to standard-of-care for endometriosis patients. Methods Feasibility was assessed through recruitment, enrollment, and adherence rates. Acceptability was evaluated through a post-intervention survey and focus group discussion 3-months after the end of the intervention. Results Of the 103 subjects recruited, 64 were randomized to the intervention group and 39 to the control group. At the start of the intervention, the study groups consisted of 29 (intervention) and 27 (control) subjects. Enrollment rates were 45.3% and 69.2%, and adherence rates were 41.4% and 100% for the intervention and control groups, respectively. Delays resulting from natural events (earthquakes, the COVID-19 pandemic) impacted enrollment and adherence rates. The most common reasons for missing an intervention were period pain (39.1%) and work-study (34.8%). There was high acceptability (>80%) of the intervention's logistics. The majority (82.4%) of subjects would continue participating in support groups regularly, and 95.7% would recommend the intervention to other patients. Conclusions We showed that EE could be translated into an acceptable integrative multi-modal therapy perceived as valuable among participants who completed the intervention. High attrition/low adherence indicates that additional refinements would be needed to improve feasibility. Acceptability data indicate that EE has the potential to be integrated into the clinical management of patients with endometriosis and other inflammatory, painful disorders. Studies are ongoing to assess the efficacy of EE in improving pain symptoms, mental health, and quality of life (QoL).

Sci Rep 2022; 12:19122. [PMID: 36352037 PMCID: PMC9645754 DOI: 10.1038/s41598-022-21173-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2022] [Accepted: 09/23/2022] [Indexed: 11/11/2022] Open
Abstract
Endometriosis is a complex and chronic disease, whose multifactorial nature has encouraged a deep investigation on the role of lifestyle factors. A strong association between alcohol intake and endometriosis risk has already been shown. We aimed to confirm this association, considering the updated literature. 23 eligible studies were identified through comprehensive literature search of PubMed and EMBASE (May 2012-October 2021). A borderline statistical significance was found comparing any alcohol consumption with no consumption (unadjusted OR 1.14; 95% CI: 0.99-1.31, p = 0.06), in contrast with a previous meta-analysis. However, we confirmed the significant association between moderate alcohol intake and endometriosis (unadjusted OR 1.22, 95% CI: 1.03-1.45, p = 0.02), also performing a sensitivity analysis (unadjusted OR 1.27, 95% CI: 1.04-1.54). Our partly divergent evidence reflects the tough challenge of isolating the impact of specific factors on the natural history of multifactorial diseases. Indeed, on one hand alcohol could be adopted by patients as a self-management therapy and on the other, it could favor the disease, promoting positive feedback with inflammatory mediators and oxidative stress. Our study encourages further investigation on the role of modifiable lifestyle factors and highlights the opportunity to adopt them to prevent or at least limit endometriosis progression.

Abstract
High-fat diet (HFD) is associated with gut microbiome dysfunction and mental disorders. However, the time-dependence as to when this occurs is unclear. We hypothesized that a short-term HFD causes colonic tissue integrity changes resulting in behavioral changes. Rats were fed HFD or low-fat diet (LFD) for a month and gut microbiome, colon, and behavior were evaluated. Behavioral despair was found in the HFD group. Although obesity was absent, the HFD group showed increased percent weight gain, epididymal fat tissue, and leptin expression. Moreover, the HFD group had increased colonic damage, decreased expression of the tight junction proteins, and higher lipopolysaccharides (LPS) in serum. Metagenomic analysis revealed that the HFD group had more Bacteroides and less S24-7 which correlated with the decreased claudin-5. Finally, HFD group showed an increase of microglia percent area, increased astrocytic projections, and decreased phospho-mTOR. In conclusion, HFD consumption in a short period is still sufficient to disrupt gut integrity resulting in LPS infiltration, alterations in the brain, and behavioral despair even in the absence of obesity.

Abstract
Introduction Endometriosis is a chronic gynecological disorder characterized by the growth of endometrial glands and stroma outside the endometrial cavity producing inflammation and pain. Previously we demonstrated that modulation of the hypothalamic pituitary adrenal (HPA) axis exacerbates the development and severity of this condition. A physically active lifestyle has been shown to confer health benefits in many chronic conditions by potentially acting as a stress buffer, thus we hypothesized that voluntary physical exercise can “realign/reset” the HPA axis resulting in reduced endometriosis symptoms in an animal model. Methods Endometriosis was induced in female Sprague Dawley rats by implanting uterine tissue next to the intestinal mesentery on day 0. Sham controls received sutures only. One group of endometriosis animals had access to a running wheel for 2 weeks prior to endometriosis induction until time of sacrifice at day 60. Sham and endometriosis controls received no exercise. All animals were examined for developed vesicles which were collected and measured. Uterine tissue was analyzed for cellular infiltration. Brain, liver, spleen, adrenal glands, leg muscles, and fat were collected, along with peritoneal fluid and blood. Results Endometriosis animals developed vesicles in 86.96% of the implants with significantly increased mesenteric fat compared to sham (p < 0.05). Exposure to exercise significantly decreased the size (p < 0.01) and number (p < 0.05) of vesicles that developed, as well as the mesenteric fat (p < 0.01). Exercised animals had higher levels of lactoferrin in peritoneal fluid, and decreased serum fractalkine and leptin. Exercise significantly increased estrogen alpha receptor expression levels (p < 0.01), while significantly decreasing estrogen receptor beta expression (p < 0.01) and macrophage infiltration (p < 0.05) in vesicles compared to non- exercised animals. Conclusions Our results suggest that voluntary physical activity might protect against endometriosis and alleviate the associated inflammation via immune modulation of the HPA axis. This offers the potential for further exploration of exercise as a complementary therapy in endometriosis patients.

Front Endocrinol (Lausanne) 2022; 13:1035158.

Abstract
BACKGROUND Epithelial-mesenchymal transition (EMT) is a complex event that drives polar epithelial cells transform from adherent cells to motile mesenchymal cells, in which are involved immune cells and stroma cells. EMT plays crucial roles in migration and invasion of endometriosis. The interaction of endometrial implants with the surrounding peritoneal micro-environment probably affects the development of peritoneal endometriosis. To date, very few studies have been carried out on peritoneal endometriosis sub-type classification and micro-environment analysis based on EMT. The purpose of this study is to investigate the potential application of EMT-based classification in precise diagnosis and treatment of peritoneal endometriosis. METHOD Based on EMT hallmark genes, 76 peritoneal endometriosis samples were classified into two clusters by consistent cluster classification. EMT scores, which calculated by Z score of 8 epithelial cell marker genes and 8 mesenchymal cell marker genes, were compared in two clusters. Then, immune scores and the abundances of corresponding immune cells, stroma scores and the abundances of corresponding stroma cells were analyzed by the "xCell" package. Futhermore, a diagnostic model was constructed based on 9 diagnostic markers which related to immune score and stroma score by Lasso-Logistic regression analysis. Finally, based on EMT classification, a total of 8 targeted drugs against two clusters were screened out by drug susceptibility analysis via "pRRophetic" package. RESULTS Hallmark epithelial-mesenchymal transition was the mainly enriched pathway of differentially expressed genes between peritoneal endometriosis tissues and endometrium tissues. Compared with cluster 2, EMT score and the abundances of most infiltrating stroma cell were significantly higher, while the abundances of most infiltrating immune cells were dramatically less. The diagnostic model could accurately distinguish cluster 1 from cluster 2. Pathway analysis showed drug candidates targeting cluster 1 mainly act on the IGF-1 signaling pathway, and drug candidates targeting cluster 2 mainly block the EGFR signaling pathway. CONCLUSION In peritoneal endometriosis, EMT was probably promoted by stroma cell infiltration and inhibited by immune cell infiltration. Besides, our study highlighted the potential uses of the EMT classification in the precise diagnosis and treatment of peritoneal endometriosis.

Abstract
Background The influence of lifestyle factors on the quality of life, incidence and tumor recurrence has been evaluated in several studies and is gaining increasing importance in cancer research. However, the extent of the influence of such lifestyle factors on the quality of life of cancer patients remains largely unclear, as does the number of patients actually pursuing these lifestyle changes. The purpose of this study was to examine the prevalence and predictors of lifestyle changes in patients with gynecological cancer.
Methods The survey consisted of a pseudonymous questionnaire that was conducted from January to May 2014 via a telephone interview with 141 patients with a gynaecological malignancy who had undergone surgery at our Department of Gynaecology and Obstetrics. Lifestyle factors (diet, physical activity, stress level, alcohol and nicotine consumption) prior to and after the diagnosis of cancer were evaluated. Results 89% (n = 125) of the patients reported lifestyle changes after being diagnosed with cancer. There was a significant association between the implementation of lifestyle changes and age as well as the use of complementary medicine. Nutrition: 66% of the patients (n = 93) consumed more fruit and vegetables and 65% ate less meat (n = 92). Physical activity: 37% (n = 52) reported no change in their exercise routine, 36% (n = 51) described a decrease, 27% (n = 38) an increase in their physical activity. Subjective feeling of stress: 77% of the patients (n = 108) described a reduction in their perceived level of stress. Nicotine consumption: 63% (n = 12) of the 19 patients who were smokers at the time of the diagnosis quit or reduced smoking thereafter. Alcohol consumption: 47% (n = 61/129) of the patients reduced their alcohol consumption. Conclusions Most of the patients from our study group implemented lifestyle changes after being diagnosed with cancer. Prospective randomized trials are needed in order to determine the benefit of lifestyle changes (physical activity, dietary habits and stress reduction) for cancer survivors. The potential impact of lifestyle on the quality of life and the trajectory of the disease should be discussed with all oncological patients.

Abstract
Objective: To describe the impact of menstrual and pelvic health disorders on a sample of Barbadian women living with one or more disorders. Design and methods: Responses from a survey taken online by a sample of women living in Barbados (⩾18 years) were assessed. Variables collected included, age, disorder(s) diagnosed, and symptoms. The Work Productivity and Activity Impairment (WPAI) Questionnaire: Specific Health Problem, was administered to measure impact on work and other activities. T-tests, chi- square tests, odds ratios, ANOVA, and multivariate analysis were conducted to estimate the associations between patient characterization, disorder characteristics and outcomes. Results: A total of 247 unique responses were received and after data were reviewed 192 responses (77.7%) from this convenience sample were analyzed. Polycystic Ovary Syndrome was the most frequently reported diagnosis (34.7%). The most frequently reported symptom was fatigue (53%). There was an OR of 2.17 (95% CI 0.54–8.74) of missing work due to menorrhagia and 2.60 (95% CI: 1.31–5.17) of missing work if diagnosed with endometriosis. The WPAI revealed endometriosis to be the condition with the most substantial impact on work in the subgroup of persons with one diagnosis, with presenteeism of 49.2%, absenteeism of 13.3% and an impact on other activities of 56.4%. Conclusion: Pelvic and menstrual disorders have a significant impact on productivity and other activities of Barbadian women. More research is necessary to elucidate the impacts of menstrual and pelvic disorders and treatments on patient outcomes.

Abstract
Endometriosis is a complex disease characterized by inflammation and the growth of endometrial- like glands and stroma outside the uterine cavity. The pathophysiology of endometriosis is not entirely understood, however, with a prevalence of ~10% of women in their reproductive years, the disease symptoms significantly affect the quality of life of millions of women globally. Metabolomic studies have previously identified specific metabolites that could be a signature of endometriosis. This approach could potentially be used as a non-invasive tool for early diagnosis and provide a better understanding of endometriosis pathophysiology. This review aims to provide insight as to how endometriosis affects the metabolome by reviewing different studies that have used this approach to design follow-up studies. The search query included the term 'endometriosis' in combination with 'metabolomics', 'lipidomics', or 'sphingolipidomics' published between 2012 and 2020. We included studies in humans and animal models. Most studies reported differences in the metabolome of subjects with endometriosis in comparison to healthy controls and used samples taken from serum, endometrial tissue, follicular fluid, urine, peritoneal fluid, or endometrial fluid. Statistically significant metabolites contributed to group separation between patients and healthy controls. Reported metabolites included amino acids, lipids, organic acids, and other organic compounds. Differences in methods, analytical techniques, and the presence of confounding factors can interfere with results and interpretation of data. Metabolomics seems to be a promising tool for identifying significant metabolites in patients with endometriosis. Nonetheless, more investigation is needed in order to understand the significance of the study results.
Lay summary
Endometriosis is a chronic disease affecting the quality of life in one out of every ten women during their reproductive years, causing pain and infertility. It is characterized by inflammation and growth of tissue like the endometrium (uterus lining) outside the uterine cavity. Studies have searched for a predictor of endometriosis-associated changes by observing small molecules necessary for metabolism on a large scale (metabolomics). Metabolomics could serve to resolve one of the biggest challenges that patients with endometriosis face: a delay in diagnosis. In this review, the authors summarize identified potential biomarkers from various bodily fluids and tissues that are characteristic of metabolic processes observed in endometriosis. Biomarkers include cell growth, cell survival, high energy demand, oxidative stress, and fatty acid levels. A metabolomics approach offers promise as a non-invasive tool to identify significant metabolite changes in patients with endometriosis, potentially leading to earlier diagnoses and new opportunities for back-translational strategies.

Abstract
Endometriosis in adolescence represents a specific variant of the disease with its own characteristics and, in some cases, even a possibly different pathogenesis. It has its own clinical presentation, diagnostic and therapeutic modalities. The condition is not rare as once thought and certainly deserves attention in view of increasing evidence of its likely progressive nature. Numerous theories for Its pathogenesis have been formulated and they have been divided into two main categories: the 'in-situ' and the 'transplantation' hypotheses. Clinical manifestations include as the prevailing symptom a persistent chronic pelvic pain, despite medical treatment, manifested under various forms: dysmenorrhea, acyclic chronic pain, acute abdominal pain and migraines. These symptoms can substantially affect the quality of life on an adolescent. At histopathology, adolescent endometriosis is characterized by a high proportion of subtle, clear, red or vesicular implants and by the rarity of deep nodules. Frequently, the picture includes ovarian endometriomas. In some adolescent girls, lesions may regress or even disappear, probably through immune suppression; in others, chronic stress, unhealthy diet or lifestyle such as high-fat diet, may accelerate lesional progression and cause symptoms. Classically, management of adolescent endometriosis has been centered on attempts to treat dysmenorrhea; today both medical and surgical modalities have the potential to improve quality of life, alleviate symptoms, prevent the development of more severe disease and minimize risks for future fertility in adolescents. Nonetheless, at present, medical treatments are considered the first line of interventions in treating young women.

Abstract
Introduction: Monitoring the impact of natural disasters such as pandemics on health and wellbeing is a public health priority. Stress is proven to affect pain intensity and quality of life of endometriosis patients. A cross-sectional study was conducted to determine whether the measures implemented to mitigate COVID-19 infections had a substantial impact on risk behaviors, endometriosis symptoms, stress, and access to healthcare. Methods: Electronic questionnaires that measured COVID-19 impact and peri-traumatic stress were disseminated through social media over June–September 2020 and completed by 82 adult patients with endometriosis living in Puerto Rico. Descriptive data analysis and correlations were done in quantitative data and systematic analysis of free text was done on qualitative responses. Results: Participants self-reported worsening of endometriosis symptoms and high levels of peri-traumatic stress, as well as changes in risk behaviors (exercise, nutrition, sedentarism, sleep) during the pandemic in comparison to the previous months. They also reported substantial barriers in access to medical appointments, scheduled procedures, and prescriptions. Electronic health modalities (telemedicine, mobile apps) were considered acceptable alternatives for gynecologic care during natural disasters. Conclusion: The COVID-19 pandemic negatively impacts the health and wellbeing of endometriosis patients while imposing substantial restrictions on access to health care. These timely insights will guide the development and implementation of plans to address barriers to health care and minimize long-term detrimental effects of natural disasters on the health of those living with stress-related disorders such as endometriosis.

Abstract
Endometriosis is a chronic inflammatory condition, which is distinguished by the presence of the endometrial-like glands and stroma outside the uterine cavity. Pain and infertility are the most commonly expressed symptoms, occurring in 60% and 40% of cases, respectively. Women with endometriosis, especially those with pelvic pain, also have a greater vulnerability to several psychiatric disorders. There is, in particular, a tendency to contract affective or anxiety disorders as well as panic-agoraphobic and substance use disorders. Endometriosis with pelvic pain, infertility and psychic vulnerability usually leads to disability and a markedly lower quality of life for women of reproductive age. Thus, the burden of endometriosis is not limited to the symptoms and dysfunctions of the disease; it extends to the social, working and emotional spheres, leading to a severe impairment of global functioning. An analysis of scientific literature revealed a close relationship between specific temperamental traits, the expression of several psychiatric symptoms, chronicity of pain, risk of substance use and lower probability of a positive outcome. Endometriosis symptoms and the impact of related psychological consequences, increased vulnerability and the possible onset of psychiatric symptoms may influence coping strategies and weaken resilience, so triggering a vicious cycle leading to a marked deterioration in the quality of life. A multidisciplinary approach consisting of a medical team composed of gynecologists, psychologists, psychiatrists, experts in Dual Disorder, algologists and sexologists, would guarantee the setting of a target and taking the best decision on a personalized treatment plan. That approach would allow the prompt detection of any psychopathological symptoms and improve the endometriosis-related physical symptoms, bringing a healthier quality of life and a greater likelihood of a positive outcome.

Abstract
INTRODUCTION Endometriosis is a chronic inflammatory gynecologic disease affecting 5-10% of women of reproductive age of all ethnicities. Symptoms of this painful condition impact the physical, mental health, and quality of life of patients. Stigma is a social determinant of health documented to negatively impact people living with chronic conditions and have been associated with social exclusion, high levels of stress, and interference with medical care. The purpose of this study was to document stigma experiences among Latina women living with endometriosis. METHODS A qualitative design using focus groups was implemented. Thematic analysis was conducted for data interpretation. A total of 50 women participated in five focus groups. RESULTS The main theme "changuería" emerged as a label applied across multiple contexts and interactions in the lives of participants, suggesting that stigmatization is an ever-present barrier among women living with endometriosis. Participants reported that relatives, partners and health professionals perceive pain during menstruation as something women should be able to manage, producing a sense of inability to disclose the extent of suffering. CONCLUSION These results highlight the importance of addressing stigma as a way to foster healthcare seeking and minimize its impact on physical, mental health, and wellbeing.

Abstract
We previously demonstrated the negative impact of stress in an animal model of endometriosis. Although its role is unclear, altered levels of vitamin D (VitD) have been found in patients with this condition. VitD signaling through the VitD receptor (VDR) has anti-proliferative properties and induces an anti-inflammatory phenotype in macrophages. We hypothesized that stress impacts the vitamin D-VDR system, influencing macrophage behavior and the local inflammatory milieu in endometriosis. Endometriosis was surgically induced in female Sprague-Dawley rats, which were then exposed to uncontrollable, controllable, or no stress for 10 days. Sham controls received sutures only. VitD levels were measured by ELISA; cytokine levels by multiplex assay and PCR; and VDR expression and macrophage numbers assessed by immunohistochemistry and immunofluorescence. VDR expression in patient samples was assessed by immunohistochemical staining of a tissue microarray. Serum VitD levels were higher in endometriosis animals compared with sham (p < 0.01) with no significant effect of stress. Uncontrollable stress increased macrophage infiltration (p < 0.01) and VDR expression in vesicles, which were attenuated by controllable stress. Macrophage infiltration correlated with vesicle area (p < 0.05), and peritoneal vitamin D levels correlated with vesicle VDR expression (r = 0.81, p < 0.01). Decreased expression of chemokine ligand 2 (p < 0.05) and TGFβ was observed in endometriosis with uncontrollable stress, whereas IL12 increased with controllable stress. Differential expression of VDR was observed in patient tissues. Stress exacerbates development of cysts in endometriosis through mechanisms that include macrophage recruitment, cytokine changes, and a potentially perturbed VitD:VDR axis, suggesting an impact on the local inflammatory environment.

Abstract
OBJECTIVE To compare the risk of ectopic pregnancy among women with and women without antidepressant prescriptions around conception and examine whether this risk differs by prepregnancy depression status. METHODS We conducted a cohort study of all pregnancies between November 1, 2008, and September 30, 2015, identified in the nationwide (American) IBM® MarketScan® Databases. At least one day's supply of antidepressants in the 3 weeks after a woman's last menstrual period defined active antidepressant use around conception. At least one depression diagnosis in the year before the last menstrual period defined prepregnancy depression. Relative risk (RR) of ectopic pregnancy was estimated using unadjusted and inverse probability of treatment (IPT)-weighted log-binomial models. RESULTS Of the 1,703,245 pregnancies, 106,788 (6.3%) women had a prepregnancy depression diagnosis. Among women with a depression diagnosis, 40,287 (37.7%) had an active antidepressant prescription around conception; the IPT-weighted risk of ectopic pregnancy was similar among women who did and did not fill an antidepressant prescription around conception (IPT-weighted RR = 1.01; 95% CI, 0.93 to 1.10). Overall, the risk of ectopic pregnancy was higher among women who had a prepregnancy depression diagnosis than women who did not have a prepregnancy depression diagnosis (IPT-weighted RR = 1.09; 95% CI, 1.04 to 1.15). CONCLUSIONS This study's findings suggest that women who have a prepregnancy depression diagnosis are at a slightly increased risk of ectopic pregnancy, and among women who have a prepregnancy depression diagnosis, the use of antidepressants around conception does not increase the risk of ectopic pregnancy.

Psychiatric comorbidity among women with endometriosis: nationwide cohort study in Sweden. Am J Obstet Gynecol 2020; 223:415.e1-415.e16. [PMID: 32112731 DOI: 10.1016/j.ajog.2020.02.033] [Citation(s) in RCA: 34] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2019] [Revised: 02/13/2020] [Accepted: 02/14/2020] [Indexed: 12/18/2022]
Abstract
BACKGROUND Endometriosis is a common gynecologic condition affecting women of reproductive age. It has been linked with greater rates of depression and anxiety in small, cross-sectional, and clinical studies. Other studies have reported that women with endometriosis have increased risk of bipolar disorder. These reports suggest that psychiatric disorders might be more common among women with endometriosis, contributing to increased burden of mental ill-health in this population of women. However, this hypothesis has not been adequately studied. OBJECTIVES In this population-based study, we investigated the overall psychiatric comorbidity among women with endometriosis, and the role of familial liability. STUDY DESIGN Several Swedish national registers were linked and used to follow all women born in Sweden in 1973-1990 for diagnosed psychiatric disorders and endometriosis from age 14 years until year 2016. Sibling comparison analyses were performed in a subsample of 173,650 families. RESULTS After adjustment for birth characteristics and education, women with endometriosis had an increased risk of being later diagnosed with depressive-, anxiety and stress-related disorders, alcohol/drug dependence, and attention-deficit hyperactivity disorder compared with the general population and with their sisters without endometriosis. The adjusted hazard ratios ranged from 1.56 (95% confidence interval, 1.29-1.88) for depressive disorders to 1.98 (95% confidence interval, 1.34-2.93) for attention-deficit hyperactivity disorder in the sibling analysis. Also, women with previous affective psychotic disorders, depressive-, anxiety and stress-related disorders, eating disorders, personality disorders, and attention-deficit hyperactivity disorder were more likely to be later diagnosed with endometriosis. The adjusted hazard ratios ranged from 1.51 (95% confidence interval, 1.30-1.76) for depressive disorders to 1.93 (95% confidence interval, 1.47-2.52) for personality disorders. CONCLUSION These findings reveal a high degree of comorbidity between endometriosis and many psychiatric disorders that was not entirely explained by shared familial confounding. Clinical practice may consider psychosocial support to women with endometriosis and treating them from a multidisciplinary perspective.

Abstract
Endometriosis is a condition in which tissue similar to the womb lining begins to grow in other sites, such as the ovaries or fallopian tubes. Endometriosis can cause pelvic pain, adhesion formation, and infertility. Here, we investigated the relationship between deterioration of endometriosis and inflammation of intraperitoneal adipose tissue in mice. We created a mouse model of endometriosis, then subjected these mice to stress loading. In the experimental mice, we measured protein expression levels of prostaglandin-E2, monocyte chemoattractant protein-1, and tumor necrosis factor-α using ELISA kits. We used quantitative real-time polymerase chain reaction to measure mRNA expression levels of inflammation-related enzymes and cytokines in lesions and adipose tissues. This study sugest that endometriotic lesions may progress in the presence of psychological stress in the presence of endometriosis. In addition, inflammation of the adipose tissue around the uterus may be involved in the development of endometriosis. However, this needs further consideration. Reducing or avoiding stress as much as possible may prevent the progression of endometriosis.

Abstract
The use of Shi Xiao San (SXS), composed of Pollen Typhae Angustifoliae and Faeces Trogopterori, can be traced back to the Song dynasty. Traditionally, SXS has been used to treat irregular menstruation, pelvic pain, progressive dysmenorrhea, and postpartum lochiorrhea. The management of adenomyosis (AM) is challenging and to the best of our knowledge there are currently no effective therapeutic strategies. Therefore, the aim of the present study was to investigate the effect of SXS on the development of adenomyosis in a mouse model. AM was induced in 60 neonatal female ICR mice by administering tamoxifen; 10 randomly selected mice were used for model identification via histopathological examination and 10 mice treated with the solvent alone were used as the normal controls. A total of sixty days after birth, the mice treated with AM were randomly divided into four groups and administered one of the following treatments: Low-dose SXS (55 mg/kg); high-dose SXS (110 mg/kg); danazol (1 mg/20 g body weight); or no treatment (model group); at the same time, the normal control group received no treatment. After 2 months of treatment, hotplate and tail-flick tests were used to assess the response to noxious thermal stimuli in the mice, and plasma samples were collected to measure corticosterone levels. Hematoxylin and eosin staining scores of myometrial infiltration and the number of AM nodules were evaluated. Furthermore, the expression of genes associated with AM-related pain was also analyzed. The results from the present study indicated that treatment with SXS decreased myometrial infiltration, alleviated generalized hyperalgesia, and lowered plasma corticosterone levels in mice with induced AM. These findings suggest that SXS effectively attenuated the development of AM, and may serve as a promising treatment approach for AM treatment.

Hypothalamic-Pituitary-Adrenal Axis Responses in Women with Endometriosis-Related Chronic Pelvic Pain. Reprod Sci 2020; 27:1839-1847.

Abstract
Some chronic pain conditions and comorbidities suppress the hypothalamic-pituitary-adrenal (HPA) axis and response to dynamic testing. We measured HPA axis responses to corticotropin-releasing hormone (CRH) administration in relation to chronic pelvic pain and endometriosis. In a cross-sectional study of women (n = 54) with endometriosis-associated chronic pelvic pain (n = 22), chronic pelvic pain alone (n = 12), or healthy volunteers (n = 20), adrenocorticotropic-releasing hormone (ACTH) and cortisol levels were measured at 0, 15, 30, and 45 min after intravenous ovine CRH administration. ACTH and cortisol delta (peak-baseline) and area under the curve (AUC) were compared by study group and assessed for association with race and menstrual and non-menstrual pain severity. HPA axis responses did not differ among the racially diverse groups or in those with pain compared with healthy volunteers. However, when stratified by race, ACTH delta (129.9 ± 130.7 vs. 52.5 ± 66.0 pg/mL; p = 0.003), ACTH AUC (4813 ± 4707 vs. 2290 ± 2900 min*pg/mL; p = 0.013), and cortisol delta (26.3 ± 21.5 vs. 13.2 ± 9.7 μg/mL; p = 0.005) were significantly higher in black (n = 10) than predominately white (non-black) subjects (n = 44; 39/44 white). In analyses among primarily white (non-black) women, greater menstrual pain severity was associated with blunted ACTH delta (p = 0.015) and cortisol delta (p = 0.023), and greater non-menstrual pain severity with blunted cortisol delta (p = 0.017). Neuroendocrine abnormalities in women with chronic pelvic pain may differ by pain manifestations and may vary by race. The higher HPA axis response in black women merits investigation in pelvic pain studies stratified by race. In white (non-black) women experiencing pain, a blunted response was related to pain severity suggesting pain affects women independently of endometriosis lesions.

Abstract
There is strong evidence from humans and animal models showing that abnormal functioning of the hypothalamic-pituitary-adrenal (HPA) axis and/or the inflammatory response system disrupts feedback regulation of both neuroendocrine and immune systems, contributing to disease. Stress is known to affect the physiology of pelvic organs and to disturb the HPA axis leading to chronic, painful, inflammatory disorders. A link between stress and disease has already been documented for many chronic conditions. Endometriosis is a complex chronic gynecological disease associated with severe pelvic pain and infertility that affects 10% of reproductive-aged women. Patients report the negative impact of endometriosis symptoms on quality of life, work/study productivity, and personal relationships, which in turn cause high levels of psychological and emotional distress. The relationship between stress and endometriosis is not clear. Still, we have recently demonstrated that stress increases the size and severity of the lesions as well as inflammatory parameters in an animal model. Furthermore, the "controllability" of stress influences the pathophysiology in this model, offering the possibility of using stress management techniques in patients. The crosstalk between stress-inflammation-pain through HPA axis activity indicates that stress relief should alleviate inflammation and, in turn, decrease painful responses. This opens up the opportunity of altering brain-body-brain pathways as potential new therapeutic option for endometriosis. The goal of this review is to gather the research evidence regarding the interaction between stress (psychological and physiological) and the development and progression of endometriosis on the exacerbation of its symptoms with the purpose of proposing new lines of emerging research and possible treatment modalities for this still incurable disease.

Abstract
BACKGROUND A large body of research highlights the importance of early-life environmental impact on the health outcome in adulthood. However, whether early-life adversity (ELA) has any impact on the development of endometriosis is completely unclear. In this study, we tested the hypothesis that ELA, as manifested by neonatal separation, can accelerate the progression of endometriosis in mouse through activation of the adrenergic receptor β2 (ADRB2) signaling pathway, leading to increased angiogenesis and progression of endometriotic lesions. METHODS Eight female Balb/C mice, in late pregnancy, were used used for this study, which later gave birth to 22 female newborn pubs. Eleven additional female Balb/C mice were also used as donors of uterine tissues. The 22 newborn pubs were randomly divided into 2 equal-sized groups, maternal separation (MS) and no separation (NS). Pubs in the MS group were separated from their dams for 3 h/day from postnatal day (PND) 1 to 21, while those in the NS control remained in the home cage with their dams. In adulthood (8-week old), 3 mice in each group were randomly selected to undergo a battery of behavior tests. The remaining 8 mice in each group were induced with endometriosis by intraperitoneal injection of uterine fragments from donor mice. Four weeks after the induction, all mice were sacrificed and their endometriotic lesions were excised for quantification and then prepared for immunohistochemistry analysis. RESULTS We confirmed that MS during infancy resulted in anxiety and depression-like behaviors as previously reported. We also found that in MS mice the lesion weight was increased by over 2 folds and generalized hyperalgesia was also significantly increased as compared with NS mice. Immunostaining analysis demonstrated that MS accelerated the development of endometriosis likely through decreased dopamine receptor D2 (DRD2) expression and activation of the ADRB2/cAMP-response element binding protein (CREB) signaling pathway, leading to increased angiogenesis and progression of endometriotic lesions. CONCLUSIONS Exposure of female mouse pups to ELA such as MS during their infancy period accelerates the progression of endometriosis, possibly through altered neuronal wiring and hyperactivity of the hypothalamic-pituitary-adrenal axis.

Abstract
We tested the hypothesis that enriched environment (EE), consisting of enlarged space, and increased physical activity and social interactions, hinders the development of endometriosis through attenuated adrenergic signaling, enhanced autophagy, and reduced leptin levels. Two mouse experiments were performed. In Experiment 1, 40 female Balb/C mice were randomly divided into four equal-sized groups, the SE (standard environment), EE, p-EE (EE instituted after endometriosis induction), and the d-EE (SE housing but received uterine fragments from EE donors) groups. Housing intervention was initiated 3 weeks before the induction of endometriosis and continued for 3 weeks after induction. In Experiment 2, 20 female mice were randomly divided into SE and EE groups, and the plasma leptin levels were measured. We measured lesion weight and hotplate latency and performed Masson trichrome staining as well as immunohistochemistry analysis of β2 adrenergic receptor (ADRB2), dopamine receptor D2 (DRD2), vascular endothelial growth factor (VEGF), and microtubule-associated protein light chain 3 (LC3). We found that EE reduced the lesion weight by 40.8% as compared with SE mice, but the reduction in p-EE and d-EE mice did not reach statistical significance. EE significantly reduced staining levels of ADRB2 and VEGF as well as the extent of lesional fibrosis but increased staining levels of LC3 and DRD2 in lesions as compared with the SE group. EE mice had reduced plasma leptin levels as compared with SE mice. Thus, EE decelerates the development of endometriosis and fibrogenesis and improved generalized hyperalgesia, possibly through increased DRD2 expression but decreased expression of ADRB2 and VEGF as well as enhanced autophagy and reduced leptin level.

Short treatment with antalarmin alters adrenal gland receptors in the rat model of endometriosis. PLoS One 2020; 15:e0227456.

Abstract
Endometriosis is a chronic inflammatory disorder in which endometrial tissue is found outside the uterine cavity. Previous reports suggest that there is a dysregulation of the hypothalamic pituitary adrenal axis during the progression of endometriosis. Our previous report showed that a short-term treatment with antalarmin, a corticotrophin releasing hormone receptor type 1 (CRHR1) antagonist decreases the number and size of endometriotic vesicles in the auto-transplantation rat model of endometriosis. Our current goal was to examine the mRNA expression of intra-adrenal receptors to better understand the mechanisms of the hypothalamic pituitary adrenal (HPA) axis involvement in endometriosis. We used two groups of female rats. The first received sham surgery or endometriosis surgery before collecting the adrenals after 7 days of the disease progression. The second group of animals received endometriosis surgery and a treatment of either vehicle or antalarmin (20 mg/kg, i.p.) during the first 7 days after endometriosis induction and then the disease was allowed to progress until day 60. Rats with sham surgery served as controls. Results showed that the mRNA expression of the mineralocorticoid (MRC2) receptor was lower in the rats after 7 days of endometriosis surgery and in rats with endometriosis that received antalarmin. In addition, the CRHR1 was significantly elevated in animals that received antalarmin and this was counteracted by a non-significant elevation in CRHR2 mRNA. The glucocorticoid receptor mRNA within the adrenals was not affected by endometriosis or antalarmin treatment. This report is one of the first to explore intra-adrenal mRNA for receptors involved in the HPA axis signaling as well as in the sympatho-adrenal signaling, calling for additional research towards understanding the role of the adrenal glands in chronic inflammatory diseases such as endometriosis.

Abstract
Clinical studies clearly indicate that endometriosis is a condition associated with high levels of chronic stress. The stress intensity correlates with pain severity and disease extension. However, it is unknown whether chronic stress represents a primary cause of endometriosis and, therefore, if avoiding or treating chronic stress may reduce the risk of developing endometriosis. Repeated, uncontrolled stress either before or after experimental endometriosis induction promotes disease mechanisms and accelerates lesion growth in rodents. Furthermore, patients with endometriosis have a heightened risk of other inflammatory and immune-related diseases, many of which have also been associated with stress. Here, we review the latest evidences regarding the relationship between chronic stress and endometriosis and discuss the potential bidirectional aspect of such association. Further research may clarify if endometriosis is a cause and/or a consequence of stress and whether stress-reducing therapies are effective to mitigate symptoms and slow down the development of endometriotic lesions.

Abstract
INTRODUCTION Endometriosis is defined as the presence of endometrial-like tissue outside the uterus, associated with chronic and inflammatory reaction. Symptoms range from dysmenorrhea, dyspareunia, chronic pelvic pain, unexplained infertility to asymptomatic. The patients' quality of life is affected by anxiety, depression and stress. We aimed to verify the prevalence and levels of psychological stress among women with endometriosis. EVIDENCE ACQUISITION The systematic review followed the PRISMA statement and the MOOSE guideline. Databases searched were MEDLINE, EMBASE, PsychNET and SciELO. The risk of bias was assessed with a modified Newcastle-Ottawa Scale. The meta-analysis of proportions used inverse variance method for pooling and random-effects model. For the stress levels we used the restricted maximum likelihood estimator for summary effects. Heterogeneity was assessed through I2 and Q statistics. Publication bias was assessed through funnel plots. Meta-regression adopted a mixed-effects model, considering patient age, endometriosis staging, stress assessment tool and data collection as categorical moderators. EVIDENCE SYNTHESIS We included 15 studies encompassing 4,619 women with endometriosis. The overall prevalence of mild/high stress was 68% (95%CI:57%-79%), I2=98% and τ2=0.0228. The mean level of stress was 41.78% (95%CI =34.05%-49.51%), I2=99.9% and τ2=83.35. Meta-regression showed relationship with endometriosis staging. CONCLUSIONS This is the first meta-analysis exploring the association between endometriosis and psychological stress. The interdisciplinary management of the disease should expand the mental health support in this patient care, beyond pain management. Finally, the attitude of the medical team acknowledging the patients' psychological stress may positively affect their treatment.

Abstract
Endometriosis is a gynecological condition affecting 10% of women in reproductive age. High rates of depression and anxiety are observed in these patients. The mechanisms underlying endometriosis-induced behavioral alterations are still elusive. Animal models provide a useful tool to study the temporal sequence and biological pathways involved in this disease and comorbid states. Here, we sought to characterize time-related behavioral alterations in rats submitted to endometriosis model (EM) induced by peritoneal auto-transplantation of uterine tissues weekly for three weeks. Corticosterone stress reactivity, oxidative stress markers - reduced glutathione (GSH), lipid peroxidation, activity of superoxide dismutase (SOD) and myeloperoxidase (MPO) - and brain-derived-neurotrophic factor (BDNF) levels in the hippocampus were also evaluated. We observed a progressive increase in anxiety-like behavior from 14th to 21st days post-EM. Despair-like behavior was observed from the 14th day post-EM on, while anhedonia and apathetic-like behaviors accompanied by increased corticosterone stress response were detected on 21 days post-EM. Increased pain sensitivity was observed from the 7th day post-EM and was accompanied by increased endometrioma weight. The pro-oxidative alterations, decreased GSH and increased SOD activity were observed on 21 days post-EM, except for lipid peroxidation that was altered from the 14th day. Decreased BDNF also occurred on the 21st day. Therefore, this study demonstrates that EM is related to several features of clinical depression and proposes the contribution of hippocampal oxidative state and neurotrophic support for the emergence of these changes. Our results support the use of this model as a useful tool to test new strategies for endometriosis-related neuropsychiatric symptoms.

Abstract
Endometriosis is mainly characterized by the presence of endometrial tissue exterior to the uterus, however, the exact pathophysiology of this disease still remains uncertain. Moreover, the incidence significantly contributes to infertility among women and hence, a novel treatment for endometriosis is widely investigated. Naringenin is a plant-derived flavonoid having anti-proliferative, anti-inflammatory, and anti-angiogenic properties in chronic and metabolic diseases. The current study was planned with an objective to demonstrate the anti-endometriotic therapeutic potential of naringenin in rats and to examine its impact on various cellular aspects with a view to define the mechanism involved. The endometrial lesion volumes, weight, serum TNF-α level and the histopathologic scores were significantly reduced in the naringenin- treated group as compared to the endometriotic control group. Naringenin ameliorated the expression of prognostic markers (TAK1, PAK1, VEGF and PCNA) involved in development and progression of endometriotic cells. Naringenin caused dose-dependent loss of mitochondrial membrane potential, induced apoptosis and inhibited proliferation in these cells. Further, a significant increase in level of Nrf2 and its downstream molecules (NQO1, HO-1) was found in endometriotic lesion, with a subsequent decrease in its repressor molecule Keap-1. Naringenin significantly modulated the expression of Nrf2 and its effector molecules downstream. It also inhibited the invasion of endometrial cells by reducing the expression of MMP-2 and MMP-9 in in-vitro primary culture. We conclude that naringenin may have a therapeutic potential in the treatment of endometriosis via induction of ROS-mediated apoptosis and its anti-invasive effects.

Abstract
INTRODUCTION Endometriosis is a gynecological disease with a severe impact on quality of life. The aim of this study is to assess mental health status in a group of women with endometriosis, investigating their clinical history, pain symptoms and systemic comorbidities. METHODS An observational cross-sectional study was performed on a group of Italian Caucasian women with endometriosis (n = 134). All patients filled the 'Patient Health Questionnaire' (PHQ), a self-administered screening tool for mental health disorders. The characteristics of endometriosis, pain symptoms and their severity, the presence and types of comorbid systemic disorders were added into the same survey. RESULTS According to PHQ algorithms, 59% of patients were affected by at least one psychiatric disorder, with a significant correlation with pain symptoms (p = 0.0026). Patients with severe pain showed a higher incidence of multiple psychiatric disorders (p = 0.026) and somatoform disorder than those with mild pain (p = 0.0009). There was no correlation between the presence of psychiatric disorders and age, BMI, parity, infertility, need for surgery, number of intervention, localization of endometriotic lesions and systemic comorbidities. DISCUSSION Women with endometriosis showed a high frequency of PHQ results positive for psychiatric disorders, with a significant association with pain severity.

Abstract
Endometriosis is a disorder in which endometrial tissue is found outside the uterus causing pain, infertility and stress. Finding effective, non-hormonal and long-term treatments for endometriosis still remains one of the most significant challenges in the field. Corticotropin releasing hormone (CRH) is one of the main signaling peptides within the hypothalamic pituitary adrenal (HPA) axis released in response to stress. CRH can affect nervous and visceral tissues such as the uterus and gut via activation of two types of CRH receptors: CRHR1 and CRHR2. Our aim was to determine if blocking CRHR1 with antalarmin will reduce endometriosis progression. In experiment 1 we induced endometriosis in female rats by suturing uterine horn tissue next to the intestinal mesentery and allowed to progress for 7 days. We determined that after 7 days, there was a significant increase in CRHR1 within endometriotic vesicles as compared to normal uterus. In Experiment 2, we induced endometriosis and administered either antalarmin (20 mg/kg, i.p.) or vehicle during the first 7 days after surgery. A separate group of sham surgery rats served as non-endometriosis controls. Endometriosis was allowed to progress until 60 days after surgery, at which time rats were tested for anxiety behaviors. At the time of sacrifice, endometriotic vesicles, uterus and blood were collected. Treatment with antalarmin significantly reduced the size (67% decrease) and number (30% decrease) of endometriotic vesicles. Antalarmin also prevented the increase in CRH and CRHR1 mRNA within endometriotic vesicles but not of glucocorticoid receptor. Endometriosis did not change anxiety behaviors in the open field and zero-maze tests and prior antalarmin administration did not modify this. Our data provides the first in-vivo demonstration for use of CRHR1 antagonist for the treatment of endometriosis opening the possibility for further exploring CRH signaling as a treatment target for this debilitating disease.

Abstract
Endometriosis is a chronic estrogen-dependent disease in which pelvic pain is the dominant symptom. The negative effects of endometriosis on the life of women with this disease can be a cause of stress. Stress levels can be measured in different ways, mostly reflecting acute stress responses. Hair cortisol measurements are a reflection of long-term systematic cortisol levels. In this study a first attempt is made to measure cortisol levels in hair of endometriosis patients in comparison with healthy controls. Moreover, it is explored whether chronic pain symptoms as well as different aspects of Health Related Quality of Life (HRQoL) are associated with hair cortisol levels in women with endometriosis. Results show that the mean hair cortisol level is significantly higher in women with endometriosis compared to healthy controls (p = 0.018). There is a positive correlation between hair cortisol level and HRQoL in patients but not in controls (Rho 0.426). The level of hair cortisol does not correlate with the reported pain intensity in patients (Rho -0.082). These results are indicative of an altered HPA-axis function in endometriosis patients, possibly caused by higher chronic stress level in these patients. Moreover, a potential explanation for the positive correlation of cortisol with the HRQoL in these patients is that patients with a high HRQoL have an adequate stress response by increasing their cortisol levels as a response to physical and emotional stress induced by the endometriosis.

Abstract
Aim: The goal of this study was to identify potential risk factors for ectopic pregnancy in women followed in German gynecological practices. Methods: The present study included pregnant women diagnosed with ectopic pregnancy and pregnant women without ectopic pregnancy followed in 262 gynecological practices between January 2012 and December 2016. The effects of demographic and clinical variables on the risk of developing ectopic pregnancy were estimated using a multivariate logistic regression model. Results: This study included 3,003 women with ectopic pregnancy and 97,194 women without ectopic pregnancy. The mean age was 31.4 years (SD=5.9 years) in ectopic pregnancy patients and 31.1 years (SD=5.6 years) in non-ectopic pregnancy patients. Women aged 36–40 (OR=1.12) and 41–45 years (OR=1.46) were at a higher risk of ectopic pregnancy than women aged 31–35 years. Prior ectopic pregnancy was strongly associated with a risk of recurring ectopic pregnancy (OR=8.17). Prior genital surgery (OR=2.67), endometriosis (OR=1.51), and eight other gynecological diseases were also positively associated with ectopic pregnancy (ORs ranging from 1.19 to 2.06). Finally, there was a 1.80-fold increase in women previously diagnosed with psychiatric disorders. Conclusions: Prior ectopic pregnancy and prior genital surgery were strongly associated with ectopic pregnancy in women followed in German gynecological practices. Psychiatric diseases had an additional impact on the risk of ectopic pregnancy.

Abstract
Objective To determine the correlations between coping strategies, depression, stress levels and pain perception in patients with endometriosis. Methods This prospective and exploratory study included 171 women undergoing treatment for endometriosis between April and August 2014. The questionnaires used were Brief COPE, Beck Depression Inventory, Lipp’s Stress Symptom Inventory for Adults and Visual Analogue Scale. Clinical data were collected from electronic medical records. Results Patients with endometriosis who used positive coping strategies had better adaptation to stress (p<0.004) and less depression (p<0.004). The presence and intensity of depression, stress and acyclic pelvic pain were directly associated (p<0.05). The intensity of dysmenorrhea was associated with the degree of depression (p<0.001), whereas acyclic pelvic pain was associated with the degree of depression (p<0.001), stress level (p<0.001) and stress type (p<0.001). Conclusion We found a positive association between coping, depression levels, type and levels of stress and pain intensity in patients with endometriosis. The use of maladaptive coping strategies focused on emotion is correlated with increase in depression and stress.

Abstract
Treatments for endometriosis include pharmacological or surgical procedures that produce significant side effects. We aimed to determine how environmental enrichment (EE) could impact the progression of endometriosis using the autotransplantation rat model. Female rats were exposed to EE (endo-EE: toys and nesting materials, 4 rats per cage, larger area enclosure) or no enrichment (endo-NE: 2 rats per cage) starting on postnatal day 21. After 8 weeks, sham surgery or surgical endometriosis was induced by suturing uterine horn tissue next to the intestinal mesentery, then allowed to progress for 60 days during which EE or NE continued. At the time of killing, we measured anxiety behaviors, collected endometriotic vesicles and uterus, and processed for quantitative real-time polymerase chain reaction for corticotropin-releasing hormone (CRH), urocortin-1, CRH receptors type 1 and type 2, and glucocorticoid receptor (GR). Endometriosis did not affect anxiety-like behaviors, yet rats in enriched conditions showed lower basal anxiety behaviors than the nonenriched group. Importantly, the endo-EE group showed a 28% reduction in the number of endometriosis vesicles and the vesicles were significantly smaller compared to the endo-NE group. Endometriosis increased CRH and GR only in the vesicles of endo-NE, and this increase was dampened in the endo-EE. However, urocortin 1 was increased in the vesicles of the endo-EE group, suggesting different pathways of activation of CRH receptors in this group. Our results suggest that the use of multimodal complementary therapies that reduce stress in endometriosis could be an effective and safe treatment alternative, with minimal side effects.

Abstract
PURPOSE We have previously shown that stress prior to induction worsens clinical presentation and inflammatory parameters in a rat model of endometriosis. This study was designed to examine whether stress during the development of endometriosis can affect the growth of endometriotic implants through nerve growth and immune alterations. METHODS Endometriosis was surgically induced in female Sprague-Dawley rats by suturing uterine horn implants onto the small intestine mesentery. Two weeks later, one group of rats (endo-stress) was subjected to a 10-day swim stress protocol. Controls had no stress (endo-no stress) or sutures only and stress (sham-stress). On day 60, all rats were killed and examined for the presence of endometriotic vesicles. The size of each vesicle was measured. The uterus and colon were removed and assessed for damage, cell infiltration, and expression of nerve growth factor (NGF), its receptors (p75 and Tropomyosin receptor kinase A (Trk-A)/pTrk-A), and calcitonin gene-related peptide, a sensory fiber marker. A differential analysis of peritoneal fluid white blood cell count was performed. RESULTS Stress significantly increased endometriotic vesicle size but not colonic damage and increased infiltration of mast cells. Significantly increased expression of NGF and its receptors was found in the uterus of animals with endometriosis receiving stress. CONCLUSIONS Stress stimulates the development of ectopic endometrial vesicles in an animal model of endometriosis and increases inflammatory cell recruitment to the peritoneum. In addition, stress promotes nerve fiber growth in the uterus.

Abstract
PURPOSE Pain in patients with endometriosis is considered a significant source of stress but does not always correlate with severity of the condition. We have demonstrated that stress can worsen endometriosis in an animal model. Here, we tested the impact of a psychological stress protocol on pain thresholds and pain receptors. METHODS Endometriosis was induced in female rats by suturing uterine horn tissue next to the intestinal mesentery. Sham rats had sutures only. Rats were exposed to water avoidance stress for 7 consecutive days or handled for 5 minutes (no stress). Fecal pellets and serum corticosterone (CORT) levels were measured as an index of anxiety. Pain perception was assessed using hot plate and Von Frey tests. Substance P, enkephalin, endomorphin-2, Mu opioid receptor (MOR), and neurokinin-1 receptor expression in the spinal cord were measured by immunohistochemistry. RESULTS Fecal pellets and CORT were significantly higher in the endo-stress (ES) group than endo-no stress (ENS; P < .01) and sham-no stress groups (SNS; P < .01). The ES rats had more colonic damage ( P < .001 vs SNS; P < .05 vs ENS), vesicle mast cell infiltration ( P < .01 vs ENS), and more severe vesicles than ENS. The ES developed significant hyperalgesia ( P < .05) but stress reversed the allodynic effect caused by endo ( P < .001). The MOR expression was significantly reduced in ENS versus SNS ( P < .05) and more enkephalin expression was found in endo groups. CONCLUSION Animals subjected to stress develop more severe symptoms but interestingly stress seems to have beneficial effects on abdominal allodynia, which could be a consequence of the stress-induced analgesia phenomenon.

Abstract
Mast cells (MC) are hemotopoietically derived tissue immune cells that are ubiquitous in the body, including neuroendocrine organs such as the hypothalamus, pineal, pituitary, ovaries, pancreas and uterus where their action is not well understood. Mast cells have historically been associated with allergies because of their rich content of histamine and tryptase, but more recently with regulation of immunity and inflammation due to their synthesis and release of numerous cytokines and chemokines. Mast cells are located perivascularly and express numerous receptors for diverse ligands such as allergens, pathogens, neurotransmitters, neuropeptides and hormones including acetylcholine, calcitonin gene-related peptide (CGRP), corticosteroids, corticotropin-releasing hormone (CRH), β-endorphin, epinephrine, 17β-oestradiol, gonadotrophins, hemokinin-A (HKA), leptin, melatonin, neurotensin (NT), parathyroid hormone (PTH), substance P (SP) and vasoactive intestinal peptide (VIP). Moreover, MC can synthesize and release most of their neurohormonal triggers, including adrenocorticotropin hormone (ACTH), CRH, endorphins, HKA, leptin, melatonin, NT, SP and VIP. Animal experiments have shown that diencephalic MC increase in number during courting in doves, while stimulation of brain and nasal MC leads to activation of the hypothalamic-pituitary-adrenal (HPA) axis. Recent evidence indicates that MC reactivity exhibits diurnal variations, and it is interesting that melatonin appears to regulate MC secretion. However, the way MC change their phenotype or secrete specific molecules selectively at different pathophysiological settings still remains unknown. Mast cells developed over 500 million years ago and may have served as the original prototype neuroimmunoendocrine cell and then evolved into a master regulator of such interactions, especially as most of the known diseases involve neuroinflammation that worsens with stress.

Abstract
Exposure to chronic stress before and well after the induction of endometriosis is reported to increase lesion sizes in rats, but it is unclear whether stress, exposed shortly after the induction of endometriosis, would also promote the development of endometriosis, nor is it clear what the underlying possible molecular mechanism is. This study was undertaken to test the hypothesis that chronic stress can promote the development of endometriosis. A prospective randomized mouse experiment was conducted that subjected mice with induced endometriosis to predator stress. In addition, a cross-sectional immunohistochemistry study was performed in ectopic and eutopic endometrial tissue samples from age- and roughly menstrual phase-matched women with ovarian endometriomas. It was found that the chronic psychogenic stress induced epigenetic changes in the hippocampus in mouse independent of endometriosis. It was also found that chronic psychogenic stress induced epigenetic changes in the hippocampus of mice with endometriosis, and seemingly activated the adrenergic signalling in ectopic endometrium, resulting in increased angiogenesis and accelerated growth of endometriotic lesions. Thus, chronic psychogenic stress promotes endometriosis development, raising the possibility that the use of anti-depressants in cases of prolonged and intense stress might forestall the negative impact of stress on the development of endometriosis.

Abstract
We have recently shown that platelets drive smooth muscle metaplasia (SMM) and fibrogenesis in endometriosis through epithelial-mesenchymal transition (EMT) and fibroblast-to-myofibroblast transdifferentiation (FMT). To see whether this is true in vivo, this prospective, randomized, and serially evaluated mouse investigation was conducted. Endometriosis was induced in female Balb/C mice, which were then randomly divided into two groups: Tanshinone IIA (TAN) and control (CTL) groups. TAN mice were treated with TAN but CTL mice received none. Every week until the 6th week after induction, five mice from each group were killed. Lesion weight was measured and lesion samples were subjected to immunohistochemistry and histochemistry analysis of platelet aggregation (CD41), E-cadherin, TGF-β1, phosphorylated Smad3, α-SMA, collagen I, CCN2, LOX, desmin and SM-MHC, and the extent of fibrosis was evaluated by Masson trichrome staining. It was found that endometriotic lesions exhibited progressive cellular changes consistent with the progressive EMT, FMT, SMM, and fibrogenesis. TAN treatment resulted in significant hindrance of EMT, FMT, SMM and fibrogenesis, and reduced lesion weight (all P-values <0.05). These data corroborate the notion that endometriotic lesions undergo progressive EMT and FMT, giving rise to SMM and ultimately fibrosis. This understanding sheds new light onto the natural history of endometriosis.

Abstract
STUDY QUESTION Does chronic stress in mice accelerate the development of endometriosis, and, if so, through what mechanism? SUMMARY ANSWER Exposure to chronic stress accelerates the development of endometriosis and exacerbates the endometriosis-associated generalized hyperalgesia, most likely through activation of the adrenoceptor β2 (ADRB2) and cAMP responsive element-binding protein (CREB). WHAT IS KNOWN ALREADY Women with endometriosis tend to have higher levels of psychological stress, which is known to impact negatively on health in general and to promote tumor growth and metastasis in particular. Exposure to chronic stress before and after the induction of endometriosis is reported to increase lesion sizes in rodents, but it is unclear whether adrenoceptors are involved or not in the stress-promoted development of endometriosis. STUDY DESIGN, SIZE, DURATION Three independent, prospective, randomized mouse experimentations. A total of 184 virgin female Balb/C mice were used. PARTICIPANTS/MATERIALS, SETTING, METHODS In Experiment 1, the mice were randomly divided into four groups: the control group, which received no stress; the before, after and both groups, which received immobilization stress before, after and both before and after the induction of endometriosis, respectively. In Experiment 2, mice were randomly divided into four groups one day after the induction of endometriosis: phosphate buffer saline (PBS) and propranolol (PROP) groups, which received the mini-pump containing, respectively, PBS only and propranolol (a non-selective ADRB antagonist) but no stress, STR+PROP and STR+PBS groups, which received stress and the mini-pump containing, respectively, propranolol and PBS. The immobilization stress started after the insertion of mini-pumps. In Experiment 3, mice were induced with endometriosis. Three days after the induction, they were randomly divided into four groups: control, ADRAa, ADRB2a, and ADRBa, which received the mini-pump containing solution only, metaraminol (a non-specific α adrenoceptor agonist), tebutaline (a specific ADRB2 agonist), or isoproterenol (a non-specific ADRB agonist), respectively. In all three experiments, the bodyweight and hotplate latency were evaluated before sacrifice 14 days after the induction. In all experimentations, the lesion weight was evaluated and the harvested ectopic endometrial tissue samples were subjected to immunohistochemistry analysis of vascular endothelial growth factor (VEGF), CD31-positive microvessels, proliferating cell nuclear antigen (PCNA), phosphorylated CREB, ADRB1, ADRB2, ADRB3, adrenergic receptor α1 (ADRA1) and ADRA2. MAIN RESULTS AND THE ROLE OF CHANCE Exposure to chronic stress accelerated the development of endometriosis and exacerbated the endometriosis-associated generalized hyperalgesia. This promotional effect is likely to be mediated through the systemic activation of the sympatho-adreno-medullary (SAM) axis, which results in subsequent release of catecholamines. The surging catecholamines may activate ADRB2 and CREB, yielding increased angiogenesis and cellular proliferation in ectopic endometrium in mice with induced endometriosis. In addition, β adrenergic receptor blockade completely abolished the promotional effect of chronic stress, likely through suppression of ADRB2 and CREB activation, thus suppressing angiogenesis and proliferation. Moreover, a non-specific adrenergic β agonist and a specific adrenergic β2 agonist, but not non-specific adrenergic α agonist, acted similarly to chronic stress, accelerating the development of endometriosis and exacerbating the generalized hyperalgesia in mice with pre-existing endometriosis. LARGE SCALE DATA NA. LIMITATIONS, REASONS FOR CAUTION This study is limited by the use of immunohistochemistry analyses only and the lack of molecular data. WIDER IMPLICATIONS OF THE FINDINGS The present study provides the experimental evidence that chronic stress can promote the development of endometriosis through the activation of ADRB2. Given ADRB2 is also expressed in human endometriosis and appears to be functional, and in light of recent awareness that adrenergic signaling plays critical roles in tumorigenesis, it is likely that adrenergic signaling may play important roles in the development of endometriosis and is potentially a target for intervention.

Abstract
The skin is considered the mirror of the soul and is affected by neurohormonal triggers, especially stress. Hair follicles, keratinocytes, mast cells, melanocytes, and sebocytes all express sex and stress hormones implicating them in a local "hypothalamic-pituitary-adrenal axis." In particular, the peptides corticotropin-releasing hormone (CRH) and neurotensin (NT) have synergistic action stimulating mast cells and are uniquely elevated in the serum of patients with skin diseases exacerbated by stress. Addressing the neurohormonal regulation of skin function could lead to new targets for effective treatment of inflammatory skin diseases.

Abstract
BACKGROUND Surgery is currently the mainstay treatment for solid tumors and many benign diseases, including endometriosis, and women tend to receive substantially more surgeries than men mainly because of gynecological and cosmetic surgeries. Despite its cosmetic, therapeutic, or even life-saving benefits, surgery is reported to increase the cancer risk and promotes cancer metastasis. Surgery activates adrenergic signaling, which in turn suppresses cell-mediated immunity and promotes angiogenesis and metastasis. Because immunity, angiogenesis, and invasiveness are all involved in the pathophysiology of endometriosis, it is unclear whether surgery may accelerate the development of endometriosis. OBJECTIVE The objective of the study was to test the hypothesis that surgery activates adrenergic signaling, increases angiogenesis, and accelerates the growth of endometriotic lesions. STUDY DESIGN This was a prospective, randomized experimentation. The first experiment used 42 female adult Balb/C mice, and the second used 90 female adult Balb/C mice. In experiment 1, 3 days after the induction of endometriosis, mice were randomly divided into 3 groups of approximately equal sizes, control, laparotomy, and mastectomy. In experiment 2, propranolol infusion via Alzet pumps was used to forestall the effect of sympathetic nervous system activation by surgery. In both experiments, mice were evaluated 2 weeks after surgery. Lesion size, hotplate latency, and immunohistochemistry analysis of vascular endothelial growth factor, CD31-positive microvessels, proliferating cell nuclear antigen, phosphorylated cyclic adenosine monophosphate-responsive element-binding protein, β2-adrenergic receptor (ADRB)-2, ADRB1, ADRB3, ADRA1, and ADRA2 in ectopic implants. RESULTS Both mastectomy and laparotomy increased lesion weight and exacerbated hyperalgesia, increased microvessel density and elevated the immunoreactivity against ADRB2, phosphorylated cyclic adenosine monophosphate-responsive element-binding protein, vascular endothelial growth factor, and proliferating cell nuclear antigen but not ADRB1, ADRB3, ADRA1, and ADRA2, suggesting activated adrenergic signaling, increased angiogenesis, and accelerated growth of endometriotic lesions. β-Blockade completely abrogated the facilitory effect of surgery, further underscoring the critical role of β-adrenergic signaling in mediating the effect of surgery. CONCLUSION Surgery activates adrenergic signaling, increases angiogenesis, and accelerates the growth of endometriotic lesions in the mouse, but such a facilitory effect of surgery can be completely abrogated by β-blockade. Whether surgery can promote the development of endometriosis in humans warrants further investigation.

Abstract
Studies have examined how endometriosis interacts with the nervous system, but little attention has been paid to opioidergic systems, which are relevant to pain signaling. We used the autotransplantation rat model of endometriosis and allowed to progress for 60 days. The brain was collected and examined for changes in endogenous opioid peptides, mu opioid receptors (MORs), and the N-methyl-d-aspartate subunit receptor (NR1) in the periaqueductal gray (PAG), since both of these receptors can regulate PAG activity. No changes in endogenous opioid peptides in met- and leu-enkephalin or β-endorphin levels were observed within the PAG. However, MOR immunoreactivity was significantly decreased in the ventral PAG in the endometriosis group. Endometriosis reduced by 20% the number of neuronal profiles expressing MOR and reduced by 40% the NR1 profiles. Our results suggest that endometriosis is associated with subtle variations in opioidergic and glutamatergic activity within the PAG, which may have implications for pain processing.
