The impact of endometriosis on depressive and anxiety symptoms and quality of life: a systematic review

Endo Belly: A Mixed Methods Exploration of Body Image, Disordered Eating, and Psychopathology in Endometriosis

OBJECTIVE

There is increasing interest in the impact of endometriosis on body image, however, there is minimal understanding of the presence and nature of disordered eating. As body image dissatisfaction is elevated in this population and a risk factor for eating disorders, it is likely that disordered eating is also elevated which has important clinical implications for prevention and intervention. The current study aimed to explore the relationships between endometriosis, body image flexibility, eating disorder psychopathology, negative affect, and self-criticism using a mixed-methods design.

METHOD

People (n = 179) with endometriosis, over the age of 18 years, and living in Australia were recruited using social media. Quantitative measures included the Body Image Acceptance and Action Questionnaire, Eating Disorder Examination Questionnaire 7-item Short Form, Depression Anxiety and Stress Scales, and the Inadequate Self subscale of the Forms of Self-Criticising/Attacking and Self-Reassuring Scale. Participants were also asked two open-ended questions that enabled reflexive thematic analysis of the impact endometriosis has on body image and eating, using Braun and Clarke's six phase process.

RESULTS

Participants were mostly female, heterosexual, White, and had a mean age of 30. The sample demonstrated high levels of eating disorder psychopathology, negative affect, and self-criticism, and low body image flexibility. Thematic analysis yielded three main themes, that were highly consistent with quantitative findings: Body disappointment, Food as an enemy, and Stolen identity and joy.

CONCLUSIONS

This study highlights the need for prevention and intervention efforts focused on reducing eating disorder psychopathology and body image concerns experienced by individuals with endometriosis.

Predictors of anxiety in endometriosis patients

PURPOSE

To evaluate the main factors influencing anxiety in endometriosis patients presenting to an endometriosis centre in Germany.

METHODS

One hundred and eighty-two patients were asked to complete the German version of the STAI (state anxiety and trait anxiety) questionnaire prior to examination for diagnosis and treatment of pelvic pain or suspected endometriosis. Typical endometriosis symptoms, main complaints, operations, type of endometriosis and planned treatment were analyzed as influencing factors of anxiety in endometriosis patients. We performed linear multiple regression analyses using the forward stepwise method to test which characteristics associated with endometriosis symptoms were associated with trait anxiety and state anxiety.

RESULTS

Analysis of the STAI results showed that higher levels of trait anxiety were found in patients with ovarian endometriosis: t (177) = 3.06, p = 0.003 and in patients with symptoms of dyspareunia: t (177) = 2.36, p < 0.020). On the other hand, patients with recurrent endometriosis showed lower levels of trait anxiety: t (177) = - 2.39, p = 0.018. Significantly higher levels of state anxiety were found in patients with persistent endometriosis: t (177) = - 2.45, p = 0.015 and in women with endometriosis who were indicated for surgical therapy: t (177) = 3.89, p < 0.001.

CONCLUSIONS

We were able to show that higher levels of ongoing anxiety in endometriosis patients are associated with dyspareunia and ovarian endometriosis, which may have a negative impact on partnership and desire to have children. On the other hand, patients with persistent endometriosis or a type of disease that requires surgery have higher levels of immediate situational anxiety.

Perceived effectiveness of endometriosis therapies on fatigue: an international survey

Graphical abstract

Abstract

Current endometriosis treatments primarily focus on pain management, despite many patients also experiencing fatigue, which significantly impacts their quality of life. This study aimed to evaluate the perceived effectiveness of endometriosis treatments in managing fatigue. An international anonymous survey was conducted using the Qualtrics platform, with participants (aged 16 years and over) and a self-reported diagnosis of endometriosis. The survey collected demographic information, the brief fatigue inventory, and perceived impact of treatments on fatigue over the past 5 years. Ethical approval was granted by the Edinburgh Medical School Research Ethics Committee. Data analysis was performed using R, with results presented as medians and interquartile ranges. From 12 April to 25 May 2023, 2,907 responses were collected. Our results showed that fatigue was significantly worsened during menstruation (median: -2, IQR: -3 to -1) and slightly worsened during ovulation (median: -1, IQR: -2 to 0). Analysis revealed limited associations between common medical treatments, such as analgesics or hormonal therapy, and improvements in fatigue symptoms. Use of gonadotrophin-releasing hormone (GnRH) agonists was linked to a worsened fatigue, reported by 54% users. Surgical interventions and changes in rest patterns showed minimal improvement, while other behavioural modifications showed little to no effect. These findings suggest that current endometriosis treatments are largely ineffective in addressing fatigue. Limitations of this study include recall bias and confounding factors, which may influence perceived effectiveness of endometriosis therapies on fatigue. This underscores the need for more comprehensive management strategies to better support patients experiencing endometriosis-associated fatigue.

Lay summary

Endometriosis is a common chronic pain condition affecting 180 million women worldwide. Many women with endometriosis also report that fatigue significantly impacts their quality of life. Despite this, fatigue management has been largely neglected, and there are limited studies that have evaluated the benefit of current endometriosis treatments on fatigue. This international survey aimed to evaluate the perceived effectiveness of various therapies for endometriosis on fatigue, including pain medication, hormonal medication, surgery and behavioural changes. Pain medication and most hormonal therapies provided limited relief. However, gonadotrophin-releasing hormone (GnRH) agonists worsened fatigue in more than half of the users. These results suggest that existing endometriosis treatments are largely ineffective in addressing fatigue, highlighting the need for improved strategies to address this symptom to enhance quality of life for women with endometriosis.

Analysis of the Biopsychosocial Impacts Associated with Endometriosis to Improve Patient Care

Endometriosis is a non-malignant, inflammatory condition that impacts individuals across various hormonal stages, including before their first menstruation, throughout their reproductive years, and after menopause. This condition arises when tissue resembling the uterine lining grows outside the uterus, resulting in inflammation and a range of symptoms, such as dysmenorrhea, pain during intercourse, chronic discomfort, and challenges with fertility. This review provides a comprehensive analysis of the medical strategies implemented to address the pathology of endometriosis, highlighting its significant impact on the quality of life of the individuals affected by this condition. Endometriosis can influence various aspects of life, including physical health, emotional well-being, social interactions, and professional performance. Usually, to assess the quality of life in women with endometriosis, validated instruments, such as different questionnaire types, are used to measure the physical, psychological, social, and reproductive health impacts. To improve the quality of life of the women experiencing endometriosis, several supportive strategies are proposed. The findings underscore the necessity of managing endometriosis through a multidisciplinary approach that encompasses both medical and surgical interventions, lifestyle modifications, and psychological support.

Effect of Endometriosis on Disease-Specific Quality of Life

OBJECTIVE

To evaluate disease-specific quality of life (QOL) in women with endometriosis and assess concurrent validity of the Endometriosis Impact Questionnaire (EIQ).

DESIGN

Observational, cross-sectional design.

SETTING

Online survey.

PARTICIPANTS

Women ages 18 to 49 years who self-reported a diagnosis of endometriosis.

MEASUREMENT

Disease-specific QOL was measured with the EIQ and the Endometriosis Health Profile-5 (EHP-5). Health-related QOL was measured with two WHOQOL-BREF questions.

RESULTS

There were 413 participants with complete data included in the analysis. Mean (SD) age at participation was 33.9 (7.1) years and at diagnosis was 28.9 (7.0) years. Responses to the EIQ demonstrated that endometriosis had the greatest effect on QOL through physical-psychosocial symptoms and fertility problems. Lifestyle behaviors related to alcohol and tobacco use were the least affected by endometriosis. Scores on the EHP-5 demonstrated similar results, with social support, self-image, and feelings of control being most impacted. Health-related QOL was also found to be impaired. Participants rated their overall QOL as neither poor nor good and their overall satisfaction with their health as dissatisfied. Concurrent validity for the EIQ was acceptable. Women who reported worse disease-specific QOL on the EIQ also had worse disease-specific QOL on the EHP-5 (p ˂ .01) and worse health-related QOL on the WHOQOL-BREF questions (p ˂ .01).

CONCLUSION

Endometriosis significantly impairs disease-specific QOL in addition to general health-related QOL. The EIQ is a valid measure of disease-specific QOL and can be used to assess the impact of endometriosis on the multiple dimensions of women's lives. It is recommended that providers use this tool to obtain a more in-depth understanding of the effect on QOL and tailor patient-specific care that targets the multidimensions of endometriosis.

Sleep Health and Psychological Wellbeing in Adult Women: A Specific Focus on Endometriosis-A Survey Study

Background: Endometriosis is a chronic, oestrogen-sensitive inflammatory disease, which can have a significant impact on women's wellbeing. Nevertheless, the sleep health of this population has been poorly investigated. This exploratory study aimed at describing sleep health, psychological wellbeing, and prevalence of endometriosis among a sample of female students and at evaluating the impact of endometriosis on sleep health and psychological wellbeing in women suffering from the disease. Methods: Women were recruited with a two-stage procedure in a cross-sectional study using online questionnaires: Insomnia Severity Index, Hospital Anxiety and Depression Scale, and Difficulties in Emotion Regulation Scale-Short form. Furthermore, specific questions were used to measure the five dimensions of sleep health: satisfaction, vigilance, efficiency, duration, and timing. Results: In the first stage of the enrolment procedure, 1068 students (18-45 years old) responded to the questionnaire, and 8.7% reported a physician diagnosis of endometriosis. Additionally, in the second stage of the enrolment procedure, 75 women were recruited through social media and reported a diagnosis of endometriosis. Then, all women with endometriosis (169) were age-matched with 169 women without the disease. Multivariate regression analyses showed a bidirectional association between sleep health and psychological wellbeing in the matched sample. Independent samples t-test showed that women with endometriosis reported more severe insomnia symptoms and lower psychological wellbeing than controls. Statistically significant differences were also found in global sleep health and satisfaction, vigilance, and efficiency. Among women with endometriosis, pain and anxiety symptoms were bidirectionally associated, while sleep health was significantly associated with disease stage and psychological difficulties. Conclusions: Considering and treating sleep difficulties in this population may contribute to an improvement in psychological wellbeing and quality of life.

Understanding Deep Endometriosis: From Molecular to Neuropsychiatry Dimension

Endometriosis is a widely spread disease that affects about 8% of the world's female population. This condition may be described as a spread of endometrial tissue apart from the uterine cavity, but this process's pathomechanism is still unsure. Apart from classic endometriosis symptoms, which are pelvic pain, infertility, and bleeding problems, there are neuropsychiatric comorbidities that are usually difficult to diagnose. In our review, we attempted to summarize some of them. Conditions like migraine, anxiety, and depression occur more often in women with endometriosis and have a significant impact on life quality and pain perception. Interestingly, 77% of endometriosis patients with depression also have anxiety. Neuroimaging gives an image of the so-called endometriosis brain, which means alternations in pain processing and cognition, self-regulation, and reward. Genetic factors, including mutations in KRAS, PTEN, and ARID1A, influence cellular proliferation, differentiation, and chromatin remodeling, potentially exacerbating lesion severity and complicating treatment. In this review, we focused on the aspects of sciatic and obturator nerve endometriosis, the emotional well-being of endometriosis-affected patients, and the potential influence of endometriosis on dementia, also focusing on prolonged diagnosis. Addressing endometriosis requires a multidisciplinary approach, encompassing molecular insights, innovative therapies, and attention to its psychological and systemic effects.

The Current Applications of Metabolomics in Understanding Endometriosis: A Systematic Review

Endometriosis is a common gynecological disease that affects approximately 10-15% of reproductive-aged women worldwide. This debilitating disease has a negative impact on the quality of life of those affected. Despite this condition being very common, the pathogenesis is not well understood. Metabolomics is the study of the array of low-weight metabolites in a given sample. This emerging field of omics-based science has proved to be effective at furthering the understanding of endometriosis. In this systematic review, we seek to provide an overview of the application of metabolomics in endometriosis. We highlight the use of metabolomics in locating biomarkers for identification, understanding treatment mechanisms and symptoms, and relating external factors to endometriosis. The literature search took place in the Web of Science, Pubmed, and Google Scholar based on the keywords "metabolomics" AND "endometriosis" or "metabolome" AND "endometriosis". We found 58 articles from 2012 to 2024 that met our search criteria. Significant alterations of lipids, amino acids, as well as other compounds were present in human and animal models. Discrepancies among studies of significantly altered metabolites make it difficult to make general conclusions on the metabolic signature of endometriosis. However, several individual metabolites were elevated in multiple studies of women with endometriosis; these include 3-hydroxybutyrate, lactate, phosphatidic acids, succinate, pyruvate, tetradecenoylcarnitine, hypoxanthine, and xanthine. Accordingly, L-isoleucine and citrate were reduced in multiple studies of women with endometriosis. Including larger cohorts, standardizing testing methods, and studying the individual phenotypes of endometriosis may lead to more separable results.

Current Status of Depression in Patients with Endometriosis and Rheumatoid Arthritis

BACKGROUND

Endometriosis often causes chronic pain and fertility issues, exacerbating the risk of depression and complicating conditions like rheumatoid arthritis, which further impacts quality of life. This study aimed to explore the detection rate of depression in patients with endometriosis and rheumatoid arthritis by using different diagnostic criteria, and to analyze the occurrence and influencing factors.

METHOD

A total of 108 patients with endometriosis combined with rheumatoid arthritis in the First Hospital of Lanzhou University from July 2021 to July 2023 were selected as samples. The internationally accepted Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5), the new depression assessment tool Hamilton Depression Scale (HAMD), and the Self-rating Depression Scale (SDS) were used to detect the incidence of depression in patients with endometriosis and rheumatoid arthritis. On the basis of the DSM-5 results, patients with concurrent depression were categorized into the observation group, and those without depression were categorized into the control group. The patients' clinical data were collected, and the impact factors were analyzed through binary logistic regression.

RESULTS

DSM-5 detected 20 patients with depression, with a detection rate of 18.52%. HAMD detected 21 patients with depression, with a detection rate of 19.44%. SDS detected 18 patients with depression, with a detection rate of 16.67%. The difference in the detection rate of depression in patients with endometriosis combined with rheumatoid arthritis among the three methods was not statistically significant (p = 0.865). Binary logistic regression analysis showed that dysmenorrhea (odds ratio (OR) = 3.589, p = 0.005), dyspareunia (OR = 2.964, p = 0.012), Visual Analog Scale score (OR = 2.545, p = 0.001), Disease Activity Score-28 score (OR = 3.828, p = 0.004), Pittsburgh Sleep Quality Index score (OR = 3.942, p = 0.004), and Health Assessment Questionnaire-Disability Index score (OR = 3.527, p = 0.008) were significant influencing factors for depression.

CONCLUSION

DSM-5, HAMD, and SDS can be used to detect depression in patients with endometriosis and rheumatoid arthritis as effective tools for depression screening. Dysmenorrhea, dyspareunia, Visual Analog Scale (VAS), Rheumatoid arthritis disease activity (DAS28), Pittsburgh Sleep Quality Index (PSQI), and Health Assessment Questionnaire-Disability Index (HAQ-DI) are influencing factors of depression in these patients.

Post-marketing safety concerns with elagolix: a disproportionality analysis of the FDA adverse event reporting system

OBJECTIVE

Elagolix is approved for the treatment of moderate-to-severe pain associated with endometriosis. However, the long-term safety of elagolix in a large sample of real-world patients is unknown.

METHODS

The U.S. Food and Drug Administration Adverse Event Reporting System (FAERS) reports were collected and analyzed from January 2019 to June 2023. Disproportionality analyses, including the reporting odds ratio (ROR), the proportional reporting ratio (PRR), the Bayesian confidence propagation neural network (BCPNN), and the multi-item gamma Poisson shrinker (MGPS) algorithms, were employed in data mining to quantify the signals of elagolix-related adverse events (AEs).

RESULTS

After removing the non-drug-related AE signals, we detected several AE signals such as hot flushes, bone pain, suicidal ideation, depression, and increased liver enzymes, which were known during the clinical trial phase. In addition to this, we detected several unexpected important AEs that were not mentioned in the drug insert, including cystitis interstitial, parosmia, and epiploic appendagitis. The median onset time of elagolix-associated AEs was 28.5 days.

CONCLUSION

Our study provides a comprehensive picture of the safety of elagolix in the post-marketing setting, while also identifying potential new AE signals. These findings emphasize the importance of continued monitoring of the potential risks of elagolix.

The vicious cycle of chronic endometriosis and depression-an immunological and physiological perspective

Endometriosis is a chronic, estrogen-dependent, proinflammatory disease that can cause various dysfunctions. The main clinical manifestations of endometriosis include chronic pelvic pain and impaired fertility. The disease is characterized by a spectrum of dysfunctions spanning hormonal signaling, inflammation, immune dysregulation, angiogenesis, neurogenic inflammation, epigenetic alterations, and tissue remodeling. Dysregulated hormonal signaling, particularly involving estrogen and progesterone, drives abnormal growth and survival of endometrial-like tissue outside the uterus. Chronic inflammation, marked by immune cell infiltration and inflammatory mediator secretion, perpetuates tissue damage and pain. Altered immune function, impaired ectopic tissue clearance, and dysregulated cytokine production contribute to immune dysregulation. Enhanced angiogenesis promotes lesion growth and survival. Epigenetic modifications influence gene expression patterns, e.g., HSD11B1 gene, affecting disease pathogenesis. Endometriosis related changes and infertility lead to depression in diagnosed women. Depression changes lifestyle and induces physiological and immunological changes. A higher rate of depression and anxiety has been reported in women diagnosed with endometriosis, unleashing physiological, clinical and immune imbalances which further accelerate chronic endometriosis or vice versa. Thus, both endometriosis and depression are concomitantly part of a vicious cycle that enhance disease complications. A multidimensional treatment strategy is needed which can cater for both endometrial disease and depression and anxiety disorders.

The impact of vitamin D treatment on pregnancy rate among endometriosis patients: a systematic review and meta-analysis

Background

Vitamin D supplementation is supposed to have an important role in the management of several endometriosis-related aspects, offering potential relief to affected individuals. Herein, the authors aim to evaluate the impact of vitamin D on pregnancy rates and clinical symptoms in women with endometriosis.

Methods

The authors extensively searched PubMed, Cochrane Library, EMBASE, Ovid MEDLINE, and CINAHL from their inception to 20 July 2023.

Results

Three randomized controlled trials involving 167 patients were included in this meta-analysis. The findings demonstrated that vitamin D supplementation exhibits efficacy in alleviating dysmenorrhea associated with endometriosis, as evidenced by a meta-analysis showing a significant reduction in dysmenorrhea (mean difference -1.41, 95% CI -2.61 to -0.22, P = 0.02). However, the impact on dyspareunia was inconclusive, with a non-significant mean difference of -0.2 (95% CI -1.62 to 1.22, P = 0.78). In contrast, dyschezia significantly decreased with vitamin D supplementation (mean difference -1.10, 95% CI -2.22 to 0.02, P = 0.05 However, the meta-analysis did not show a significant effect of vitamin D on chronic pelvic pain associated with endometriosis.

Conclusion

While antioxidant vitamin D supplementation demonstrates general effectiveness in alleviating endometriosis symptoms, such as dysmenorrhea, dyspareunia, and dyschezia, the existing literature lacks direct investigations into the specific impact of vitamin D on enhancing pregnancy rates among endometriosis patients. This observation prompts various hypotheses, suggesting that the positive effects of vitamin D supplementation on endometriosis-related symptoms may indirectly contribute to improved pregnancy outcomes and enhanced fertility.

A Psychological Point of View on Endometriosis and Quality of Life: A Narrative Review

Endometriosis is a chronic gynecological disorder with a multifactorial etiology that has not yet been fully elucidated. What is known, however, are the pathological tissue dynamics that lead to the complex symptoms that women suffer from. The known symptoms are mainly fertility problems and pain. Both dimensions have an impact that varies from case to case, but that is certainly decisive concerning a woman's health, specifically by affecting the overall quality of life (QoL). In this publication, we will deal with the descriptive aspects of endometriosis's pathology and then present a review of the aspects impacting QoL and their psycho-social consequences. Finally, the experience of pain in the context of the mind-brain-body relationship will be discussed, describing the complexity of this dimension and emphasizing the importance of a multi-professional approach that considers the relevance of the contribution that a psychotherapy intervention based on up-to-date neurobiological models can make for women with endometriosis. A review of the literature and current knowledge on the neural and psychological aspects of pain lead to the conclusion that it is of the utmost importance to provide informed psychological support, alongside medical treatments and sexual counseling, to patients with endometriosis.

Translocator protein expression and localization in human endometrium and endometriosis: A potential target for a noninvasive diagnosis?

The limitations of current imaging methods to detect small or superficial endometriotic lesions prompt the search for new molecular targets. TSPO is an 18 KDa protein located in the outer mitochondrial membrane, which can be traced by positron emission tomography (PET) using specific ligands. TSPO is located mostly in neurons and inflammatory sites outside the brain. We hypothesized that it might also be expressed in the human endometrium and endometrial-like tissue, being a target for molecular imaging of endometriosis. This prospective cross-sectional study included 28 women with endometriosis and 11 endometriosis-free controls. Endometriotic lesions (n = 49) and normal peritoneum (n = 13) from endometriosis patients were obtained during laparoscopy, while samples of eutopic endometrium from patients with endometriosis (n = 28) and from control women (n = 11) were collected in the operating room using a flexible device. TSPO mRNA expression was evaluated by quantitative reverse-transcription real-time PCR while protein expression was evaluated by immunohistochemistry with a monoclonal antibody antihuman TSPO. TSPO mRNA expression was detected in an invariable fashion in all tissue types evaluated; however, TSPO protein was found to be more abundant in the glandular epithelium than in the stroma, both in the endometrium and in the endometriotic lesions. Interestingly, hormone therapies did not alter the expression of TSPO, and its presence was mostly negative in tissues adjacent to endometriotic implants. As a proof of concept, the protein expression pattern of TSPO in endometriotic tissue and along the adjacent areas suggests that TSPO-based molecular imaging might be used for noninvasive endometriosis detection.

Endometriosis and mental health disorders: identification and treatment as part of a multimodal approach

Endometriosis is a disease marked by more than just pain and infertility, as it transcends the well-characterized physical symptoms to be frequently associated with mental health issues. This review focuses on the associations between endometriosis and anxiety, depression, sexual dysfunction, and eating disorders, all of which show a higher prevalence in women with the disease. Studies show that pain, especially the chronic pelvic pain of endometriosis, likely serves as a mediating factor. Recent studies evaluating genetic predispositions for endometriosis and mental health disorders suggest a shared genetic predisposition. Healthcare providers who treat women with endometriosis should be aware of these associations to best treat their patients. A holistic approach to care by gynecologists as well as mental health professionals should emphasize prompt diagnosis, targeted medical interventions, and psychological support, while also recognizing the role of supportive relationships in improving the patient's quality of life.
