Spectrum of symptoms in women diagnosed with endometriosis during adolescence vs adulthood

Characteristics and Preoperative Management of Adolescent Patients with Pathology-Confirmed Endometriosis: A Multi-Institutional Study

STUDY OBJECTIVE

This multi-institutional, observational, retrospective cohort study aimed to characterize the demographics and preoperative medical management of patients with pathology-confirmed endometriosis.

METHODS

We reviewed patients <22 years at 8 tertiary care pediatric hospitals in the Midwestern United States who underwent diagnostic laparoscopy and had biopsy-confirmed endometriosis. Patients were identified through pathology records. Demographics, medical history, clinical symptoms, and prior medical management were extracted. Descriptive statistics were computed.

RESULTS

Among 305 patients, median age at first presentation to pediatric and adolescent gynecology (PAG) was 15.6 years (interquartile range: 14.2-17.1). Most patients were White (83.3%) and most had commercial insurance (70.5%). Only 4.3% had a diagnosis of endometriosis prior to their initial presentation to PAG. Common symptoms included progressive dysmenorrhea (76.7%), heavy menstrual bleeding (50.8%), missed school/activities due to dysmenorrhea (55.1%). Patients sought care for their symptoms from a range of providers in addition to PAG, including primary care/adolescent medicine (75.1%), gastroenterology (18.7%), adult gynecology (22.3%), and physical therapy (13.4%). Nearly all patients (92.8%) tried oral hormonal menstrual suppression prior to laparoscopy. Hormonal management included combined oral contraception (62.3%), medroxyprogesterone acetate injection (15.7%), ≤5mg daily norethindrone (14.8%), >5mg daily norethindrone (13.4%), hormonal intrauterine system (13.1%), and contraceptive implant (5.3%).

CONCLUSIONS

Patients with pathology-proven endometriosis typically presented with progressive dysmenorrhea, missed school or activities, and heavy menstrual bleeding. They sought care from a variety of providers and while most tried hormonal management of symptoms, the method used varied.

Plasma metabolites associated with endometriosis in adolescents and young adults

STUDY QUESTION

What are the plasma metabolomics profiles associated with endometriosis in adolescents and young adults?

SUMMARY ANSWER

Our findings show dysregulation of plasma metabolomic profiles in adolescents and young adults with endometriosis, revealing systemic elevation of fatty acyls and ceramides in endometriosis cases compared to controls.

WHAT IS KNOWN ALREADY

Endometriosis is a gynecologic disease often presenting with severe pelvic pain impacting around 200 million reproductive-aged women worldwide. However, little is known about the pathophysiology and molecular features of endometriosis diagnosed during adolescence and young adulthood.

STUDY DESIGN, SIZE, DURATION

We conducted a cross-sectional analysis including 190 laparoscopically confirmed endometriosis cases and 120 controls who participated in The Women's Health Study: From Adolescence to Adulthood, which enrolled participants from 2012 to 2018. Control participants were females without a diagnosis of endometriosis enrolled from the same clinics as the cases or recruited from the general population. Among the cases, 81 had blood samples collected before and after surgery.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Plasma metabolites were measured in blood collected at enrollment using liquid chromatography-tandem mass spectrometry, and a total of 430 known metabolites were evaluated in our analysis. We used linear regression adjusting for age at blood draw, BMI, hormone use, and fasting status at blood draw. Metabolite set enrichment analysis (MSEA) was used to identify metabolite classes. Number of effective tests (NEF) and false discovery rate (FDR) were used for multiple testing correction.

MAIN RESULTS AND THE ROLE OF CHANCE

The median age was 17 years for endometriosis cases and 22 years for controls. The majority of endometriosis cases had rASRM stage I or II (>95%). We identified 63 plasma metabolites associated with endometriosis (NEF < 0.05). Endometriosis cases had higher levels of plasma metabolites associated with proinflammatory response [e.g. eicosatrienoic acid (β = 0.61, 95% CI = 0.37, 0.86)], increased oxidative stress response [e.g. xanthine (β = 0.64, 95% CI = 0.39, 0.88)], and downregulation of metabolites related to apoptosis [glycocholic acid (β = -0.80, 95% CI = -1.04, -0.56)]. MSEA revealed increased fatty acyls (FDR = 2.3e-4) and ceramides (FDR = 6.0e-3) and decreased steroids and steroid derivatives (FDR = 1.3e-4) in endometriosis cases compared to controls. When we examined the changes in plasma metabolite profiles before and after surgery among endometriosis cases, 55 endometriosis-associated metabolites significantly changed from before to after surgery. MSEA revealed steroids and steroid derivatives (FDR = 8.1e-4) significantly increased after surgery, while fatty acyls (FDR = 1.2e-4) significantly decreased after surgery. Ceramides did not change from pre- to post-surgery and were elevated in post-surgical blood compared to controls (FDR = 3.9e-3).

LIMITATIONS, REASONS FOR CAUTION

Our study population mainly consists of self-reported non-Hispanic, white individuals and endometriosis cases with superficial peritoneal lesions only, so the generalizability may be limited. Furthermore, despite our large study population of adolescents and young adults with endometriosis, sample size was limited to conduct detailed stratified analyses of plasma metabolomic profiles, especially by post-surgical pelvic pain outcomes.

WIDER IMPLICATIONS OF THE FINDINGS

Our study includes the utilization of state-of-the-art metabolomics technology with high reproducibility to comprehensively investigate the metabolites that were associated with endometriosis diagnosed in adolescents and young adults. Our results suggest a positive impact of endometriosis-related surgery for some, but not all, on systemic metabolic dysregulation in young patients with endometriosis. These results warrant further investigation on whether and how persistent systemic changes despite treatment may lead to long-term chronic disease risk among those diagnosed with endometriosis.

Noninvasive Diagnosis of Endometriosis in Adolescents and Young Female Adults: A Systematic Review

STUDY OBJECTIVES

Our aim was to review the evidence concerning the noninvasive diagnosis of endometriosis in adolescents.

METHODS

A systematic review was written following the SWiM reporting guidelines. The study research was made across three databases (MEDLINE/PubMed, Scopus, and Web of Science) to identify articles about the adolescent population and the diagnosis of endometriosis through noninvasive methods. The search included the keywords "endometriosis," "adolescents," "diagnosis," "ultrasound," and "MRI." Only English-language articles were considered, and those published prior to 2000 were excluded. The established outcomes focused on clinical symptoms, ultrasound (US), and magnetic resonance imaging (MRI) findings suggestive of endometriosis.

RESULTS

We included 26 articles, mostly comprising case series and cross-sectional studies. The pooled analysis involved 2,299 female adolescents (age range 8-25 years old) with clinically suspected, imaged, and/or surgically confirmed endometriosis. The most frequently reported symptom was dysmenorrhea, followed by chronic pelvic pain. Among adolescents clinically suspected of endometriosis undergoing ultrasound (US), 32.8% exhibited at least one sign of endometriosis. Of the 167 patients with ultrasound-diagnosed endometriosis, 48.5% had deep infiltrating endometriosis (DIE), and 45.5% had an endometrioma detected. Three studies assessed MRI findings, revealing that 49.8% presented with signs of endometriosis.

CONCLUSIONS

Dysmenorrhea and chronic pelvic pain stand out as key symptoms of adolescent endometriosis. Although their diagnostic accuracy varies, US and MRI have emerged as valuable tools for diagnosing the disease. While the US may have limitations, especially in detecting subtle lesions, MRI shows promise, even in cases with normal previous ultrasounds. Early recognition and proactive diagnosis are crucial for improving the management of endometriosis in adolescents.

Endometriosis in Adolescents: A Closer Look at the Pain Characteristics and Atypical Symptoms: A Prospective Cohort Study

Background/Objectives: Endometriosis affects up to 10% of women of reproductive age and about 47% of adolescents with pelvic pain. Symptoms include dysmenorrhea, dyspareunia, and chronic pelvic pain (CPP). Adolescents often present atypical symptoms that can make endometriosis more difficult to diagnose. This study aimed to compare characteristics of pain, atypical symptoms, and the effects of hormonal treatments between adolescents and adults with endometriosis. Methods: A total of 238 women with endometriosis were included: 92 aged 12-18 (group A) and 146 over 18 (group B). Data on menarches, cycle length, comorbidities, dysmenorrhea, dyspareunia, CPP, analgesic use, pain characteristics, atypical symptoms, and endometrioma size were recorded. The efficacy, compliance, and side effects of hormonal treatments were also assessed. Quality of life (QoL) was measured using the SF-12 questionnaire at baseline and after six months of therapy. Results: Adolescents had earlier menarche (p < 0.001), longer menstrual periods (p < 0.001), and higher analgesic use (p = 0.001) compared to adults. Dysmenorrhea was more frequent (p = 0.01), lasted longer (p < 0.001), and was associated with higher pain scores (p < 0.001) in adolescents. CPP was more common in adolescents (p < 0.001), often described as "confined" (p = 0.04) and "oppressive" (p = 0.038), while adults reported it as "widespread" (p = 0.007). Headaches (p < 0.001) and nausea (p = 0.001) were also more frequent in adolescents. Both groups showed significant improvement in QoL with hormonal treatment (p < 0.001) and reported minimal side effects. Conclusions: Adolescents with endometriosis often present with earlier menarche, longer menstrual periods, more severe dysmenorrhea, and atypical symptoms. Hormonal contraceptives and dienogest are effective and safe treatments that improve pain and QoL.

MRI for endometriosis in adolescent patients

Endometriosis, a chronic condition that often starts in adolescence, can have a significant impact on quality of life due to symptoms of dysmenorrhea and pelvic pain. Although laparoscopy with direct visualization and pathologic correlation is the reference standard for the diagnosis of endometriosis, some authors have called for a greater emphasis on clinical diagnosis - including imaging. Magnetic resonance imaging (MRI) provides highly reproducible, large field of view, multiplanar, and multiparametric imaging of pelvic endometriosis and is well tolerated in adolescent patients. As such, pediatric radiologists need to be familiar with the manifestations of endometriosis on MRI and how these findings may differ from those seen in adult populations.

Time to Diagnose Endometriosis: Current Status, Challenges and Regional Characteristics-A Systematic Literature Review

BACKGROUND

Endometriosis diagnosis reportedly faces delays of up to 10 years. Despite growing awareness and improved guidelines, information on the current status is limited.

OBJECTIVES

To systematically assess the published evidence on the status of time to diagnosis in individuals with endometriosis, with respect to the definition of time to diagnosis, geographical location and patient characteristics.

SEARCH STRATEGY

MEDLINE (via PubMed) and Embase were searched for publications reporting time to diagnosing endometriosis since 2018. No restrictions to population or comparators were applied. All publications were screened by two independent reviewers.

SELECTION CRITERIA

Search results were limited to primary publications of randomised controlled trials, non-randomised trials and observational studies. Case reports, secondary publications and grey literature were excluded. No restrictions were made regarding language, provided that an English title and abstract were available.

DATA COLLECTION AND ANALYSIS

Publications were assessed with respect to time to diagnosis, diagnostic methods, study type, study country and potential bias.

MAIN RESULTS

The 17 publications eligible for inclusion in this literature review were all observational studies. The publications reported diagnosis times between 0.3 and 12 years, with variations depending on the definition of time to diagnosis (overall, primary, or clinical), geographical location and characteristics of the included study population. Evidence was of poor to good quality overall.

CONCLUSIONS

Diagnostic delay is still present, primarily driven by physicians, and this review underscores the need for standardised definitions, increased awareness and targeted diagnostic interventions.

Menstrual Disorders in Adolescence: Diagnostic and Therapeutic Challenges

Background: Adolescence is the period of life between the ages of 10 and 19. This period is essentially dominated by puberty. The first menstruation, called menarche, occurs, on average, at the age of 12-13. The period after menarche, especially the first 2 years, is characterized by anovulatory cycles, which can be accompanied by menstrual irregularities. This review aims to describe the current status of the diagnostic and therapeutic challenges of the physiological and pathological causes of menstrual irregularities in adolescence and evaluates the benefits from interdisciplinary collaboration to ensure optimal care. Methods: A systematic literature search was conducted in the PubMed database in April 2024 using the following term: "menstrual disorder adolescence". A total of 1724 abstracts were screened, and relevant articles from the last 10 years were included. In addition, a supplementary topic-relevant literature search of the guidelines of the European Society of Human Reproduction and Embryology (ESHRE) and the guidelines of the Arbeitsgemeinschaft der wissenschaftlichen medizinischen Fachgesellschaft (awmf) was carried out. Results: In addition to cycle irregularities that occur physiologically as a result of anovulatory cycles in the context of the immaturity of the hypothalamic-pituitary-gonadal axis, there are other cycle abnormalities that can be classified as pathological and need to be recognized and treated. Conclusions: Increasing awareness of the various specialist disciplines of physiological and pathological cycle abnormalities in adolescence and interdisciplinary cooperation between them can have a positive influence on the quality of life of adolescent women with cycle abnormalities.

Prevalence of Temporomandibular Disorders in Adult Women with Endometriosis

Background/Objectives: The prevalence of endometriosis varies between 10% and 18%, while temporomandibular disorders (TMDs) concern between 29 and 34% of the general population. Both conditions share similar etiological factors and symptoms such as widespread, chronic pain. Therefore, both are qualified as Chronic Overlapping Pain Conditions. Even though TMDs and endometriosis appear to be comorbidities, up until now, no research has examined how the incidence rates compare between them. Thus, this study aimed to analyze the prevalence of TMD symptoms in women with endometriosis in the Polish population. Methods: 163 adult women with endometriosis, aged 32.41 ± 6.76 years, completed an anonymous online survey regarding their medical history and TMD symptoms. The participants were screened for TMD symptoms using two questionnaires-3Q/TMD and TMD Pain Screener (part of the DC/TMD protocol). The history mainly consisted of a chronology of symptoms' appearance, medical consultations, and final confirmation of the diagnosis, to establish delay time. Results: The analysis revealed that 77.3% of women with endometriosis showed TMD symptoms, and 49.08% of the whole studied population showed important pain levels. Then, the sample was divided into two groups according to the 3Q/TMD questionnaire-a TMD and an nTMD group. The results showed significantly higher pain levels in the TMD group (r = 0.721) compared to non-symptomatic subjects. The mean patients' delay time (T1) was 2.81 ± 4.40 years, and the mean doctors' delay (T2) was 5.32 ± 5.65 years. Conclusions: The results provide a new insight into the relationship between endometriosis and TMD. The prevalence of the latter condition was found to be high, creating a strong recommendation for the use of TMD screening tools in this particular population.

Managing the neuroinflammatory pain of endometriosis in light of chronic pelvic pain

INTRODUCTION

Endometriosis affects 5% to 10% of reproductive age women and may be associated with severely painful and debilitating symptoms as well as infertility. Endometriosis involves hormonal fluctuations, angiogenesis, neurogenesis, vascular changes and neuroinflammatory processes. The neuroinflammatory component of endometriosis makes it a systemic disorder, similar to other chronic epithelial inflammatory conditions.

AREAS COVERED

Inflammatory mediators, mast cells, macrophages, and glial cells play a role in endometriosis which can result in peripheral sensitization and central sensitization. There is overlap between chronic pelvic pain and endometriosis, but the two conditions are distinct. Effective treatment is based on a personalized approach using a variety of pharmacologic and other treatment options.

EXPERT OPINION

Hormonal therapies are a first-line approach, but endometriosis is a challenging condition to manage. 'Add-back' hormonal therapy has been effective. Painful symptoms are likely caused by the interplay of multiple factors and there may be a neuropathic component. Analgesics and anticonvulsants may be appropriate. A holistic approach and multimodal treatments are likely to be most effective. In addition to pharmacologic treatment, there are surgical and alternative medicine options. Endometriosis may also have a psychological component.

Dysmenorrhea and Endometriosis in Adolescents

Endometriosis is a chronic disorder often beginning in adolescence. Despite the high prevalence of the disease and the symptom burden, adolescents may experience suboptimal management and a delay in diagnosis. The symptoms and laparoscopic findings in adolescents with endometriosis may differ from that of adults. This article aims to equip readers with the tools necessary to diagnose and manage endometriosis in adolescents.

Understanding diagnostic delay for endometriosis: A scoping review using the social-ecological framework

Diagnostic delay for endometriosis is a well-established phenomenon. Despite this, little is known about where in the health care system these delays occur or why they occur. Our review is the first attempt to synthesize and analyze this international evidence. A systematic scoping review with a pre-specified protocol incorporated the literature on diagnostic delay for endometriosis using the social-ecological theoretical framework. Four databases (PubMed, MEDLINE, EMBASE, PsychINFO) were searched from inception to September 2023. The search yielded 403 studies, 23 of which met the inclusion criteria. Most were from high-income country researchers. The average diagnostic delay reported across studies was 6.8 years (range 1.5-11.4 years) but this masked the very wide differences reported between countries. Considering the impact on individuals and the health system, addressing diagnostic delay for endometriosis must remain a priority for researchers, health care providers and policy makers.

Prevalence of sleep disturbances in endometriosis patients: a systematic review and meta-analysis

Objective

This study systematically analyzes the prevalence of sleep disturbance in patients with endometriosis.

Methods

The PubMed, Web of Science, Embase, Wanfang, China National Knowledge Internet Database (CNKI), China Science and Technology Journal Database were searched from their establishment to January 2024, using the search terms endometriosis and sleep disturbance to collect relevant literature on the prevalence of sleep disturbance in patients with endometriosis. Two researchers independently screened the literature, extracted data, and evaluated the risk of bias. The prevalence of sleep disorders in patients with endometriosis was systematically analyzed using Stata17.0 software.

Results

Sixteen studies with 2573 participants were included. The prevalence of sleep disturbance in patients with endometriosis was 70.8% (95% confidence interval: 60.7%~80.9%). The said prevalence was higher in China than in Iran and the European countries (78.2 vs. 57.6 vs. 64.4, Q=9.27, P=0.010) and increased significantly since 2018 (79.0 vs. 61.3, Q=3.97, P=0.046). This prevalence was significantly higher in the cohort study than that in cross-sectional and case-control studies (84.0 vs. 74.0 vs. 59.5, Q=7.16, P=0.028).

Conclusion

The prevalence of sleep disturbance is high in patients with endometriosis, particularly in China and its prevalence has increased significantly in recent years. Appropriate interventions are recommended to effectively prevent or minimize sleep disturbances in patients with endometriosis.

Endometriosis risk and hormonal contraceptive usage: A nationwide cohort study

OBJECTIVE

To investigate whether an early need of hormonal contraceptive (HC), or a failure to find a suitable method, are warning signs for endometriosis.

DESIGN

A retrospective cohort study.

SETTING

Sweden.

POPULATION

The cohort consisted of 720 805 women aged 12-27 years during the period 2005-2017. All women, regardless of whether they received a diagnosis of endometriosis or not (reference group), were included.

METHODS

We used data from Swedish national registers. Risks are expressed as crude and adjusted hazard ratios (HRs and aHRs, respectively) with 95% confidence intervals (95% CIs), adjusted for age, education level, civil status, parity, country of birth, and diagnoses of infertility, dysmenorrhea or depression.

MAIN OUTCOME MEASURES

A diagnosis of endometriosis between 12 and 27 years of age.

RESULTS

During this period, 3268 women were diagnosed with endometriosis (0.45%). Women who started HC at the ages of 12-14 years had a higher risk of receiving the diagnosis (aHR 2.53, 95% CI 2.21-2.90) than those who began at age 17 years or older. Having tried more types of HCs was associated with a twofold increased risk of endometriosis (more that three types of HC, aHR 2.31, 95% CI 1.71-3.12). Using HC for more than 1 year was associated with a decreased risk of endometriosis (>1 year, aHR 0.53, 95% CI 0.48-0.59). Women with endometriosis more commonly had dysmenorrhea, depression or infertility.

CONCLUSIONS

The use of HCs at an early age and a failure to find a suitable HC were identified as warning signs of later receiving an endometriosis diagnosis. A longer duration of HC usage reduced the risk of receiving the diagnosis.

Subgroups of pelvic pain are differentially associated with endometriosis and inflammatory comorbidities: a latent class analysis

ABSTRACT

Chronic pelvic pain is heterogeneous with potentially clinically informative subgroups. We aimed to identify subgroups of pelvic pain based on symptom patterns and investigate their associations with inflammatory and chronic pain-related comorbidities. Latent class analysis (LCA) identified subgroups of participants (n = 1255) from the Adolescence to Adulthood (A2A) cohort. Six participant characteristics were included in the LCA: severity, frequency, and impact on daily activities of both menstruation-associated (cyclic) and non-menstruation-associated (acyclic) pelvic pain. Three-step LCA quantified associations between LC subgroups, demographic and clinical variables, and 18 comorbidities (10 with prevalence ≥10%). Five subgroups were identified: none or minimal (23%), moderate cyclic only (28%), severe cyclic only (20%), moderate or severe acyclic plus moderate cyclic (9%), and severe acyclic plus severe cyclic (21%). Endometriosis prevalence within these 5 LCA-pelvic pain-defined subgroups ranged in size from 4% in "none or minimal pelvic pain" to 24%, 72%, 70%, and 94%, respectively, in the 4 pain subgroups, with statistically significant odds of membership only for the latter 3 subgroups. Migraines were associated with significant odds of membership in all 4 pelvic pain subgroups relative to those with no pelvic pain (adjusted odds ratios = 2.92-7.78), whereas back, joint, or leg pain each had significantly greater odds of membership in the latter 3 subgroups. Asthma or allergies had three times the odds of membership in the most severe pain group. Subgroups with elevated levels of cyclic or acyclic pain are associated with greater frequency of chronic overlapping pain conditions, suggesting an important role for central inflammatory and immunological mechanisms.

Adolescent dysmenorrhoea in general practice: tensions and uncertainties

This Perspectives article reflects on findings from our systematic review about adolescent dysmenorrhoea Q, drawing on sociology of diagnosis theory. We consider tensions and uncertainties between presentation with symptoms of dysmenorrhoea and processes of symptom categorisation and diagnosis in adolescents, tracing these through research and clinical guidance, considering possible implications for clinical practice. We argue that challenges in distinguishing between primary and secondary dysmenorrhoea in research translate into challenges in differentiation in clinical practice. We argue that framing this distinction as clear cut and straightforward belies the well-documented challenges in diagnosis of endometriosis, and that not recognising uncertainty and complexity inherent in this task may benefit neither clinicians nor patients.

Transgender and non-binary people's experience of endometriosis

There is a lack of research on gender diverse people's experiences with endometriosis. We explored the experience of 11 transgender and non-binary people with endometriosis using phenomenology. We collected data through multiple interviews and diaries and constructed two themes using hermeneutic analysis: (1) Unhomelikeness of Living with Endometriosis and being Gender Diverse, and (2) Towards a Homelikeness of Living with Endometriosis as a Gender Diverse Individual, which we discussed in relation to Svenaeus Phenomenology of Medicine. Unhomelikeness is an experience of disconnection with our bodies and being-in-the-world as a result of living with a chronic disease. We show how gender diverse people with endometriosis may have additional layers of unhomelikeness due to further diagnostic delays, endometriosis symptoms that may trigger gender dysphoria and experiences with treatment that are not inclusive of their gender identity. We advocate for additional support and awareness for gender diverse people with endometriosis.

Plasma proteins and persistent postsurgical pelvic pain among adolescents and young adults with endometriosis

BACKGROUND

Noninvasive biomarkers that predict surgical treatment response would inform personalized treatments and provide insight into potential biologic pathways underlying endometriosis-associated pain and symptom progression.

OBJECTIVE

To use plasma proteins in relation to the persistence of pelvic pain following laparoscopic surgery in predominantly adolescents and young adults with endometriosis using a multiplex aptamer-based proteomics biomarker discovery platform.

STUDY DESIGN

We conducted a prospective analysis including 142 participants with laparoscopically-confirmed endometriosis from the Women's Health Study: From Adolescence to Adulthood observational longitudinal cohort with study enrollment from 2012-2018. Biologic samples and patient data were collected with modified World Endometriosis Research Foundation Endometriosis Phenome and Biobanking Harmonization Project tools. In blood collected before laparoscopic ablation or excision of endometriosis, we simultaneously measured 1305 plasma protein levels, including markers for immunity, angiogenesis, and inflammation, using SomaScan. Worsening or persistent postsurgical pelvic pain was defined as having newly developed, persistent (ie, stable), or worsening severity, frequency, or persistent life interference of dysmenorrhea or acyclic pelvic pain at 1-year postsurgery compared with presurgery. We calculated odds ratios and 95% confidence intervals using logistic regression adjusted for age, body mass index, fasting status, and hormone use at blood draw. We applied Ingenuity Pathway Analysis and STRING analysis to identify pathophysiologic pathways and protein interactions.

RESULTS

The median age at blood draw was 17 years (interquartile range, 15-19 years), and most participants were White (90%). All had superficial peritoneal lesions only and were treated by excision or ablation. One-year postsurgery, pelvic pain worsened or persisted for 76 (54%) of these participants with endometriosis, whereas pelvic pain improved for 66 (46%). We identified 83 proteins associated with worsening or persistent pelvic pain 1-year postsurgery (nominal P<.05). Compared with those with improved pelvic pain 1-year postsurgery, those with worsening or persistent pelvic pain had higher plasma levels of CD63 antigen (odds ratio, 2.98 [95% confidence interval, 1.44-6.19]) and CD47 (odds ratio, 2.68 [95% confidence interval, 1.28-5.61]), but lower levels of Sonic Hedgehog protein (odds ratio, 0.55 [95% confidence interval, 0.36-0.84]) in presurgical blood. Pathways related to cell migration were up-regulated, and pathways related to angiogenesis were down-regulated in those with worsening or persistent postsurgical pelvic pain compared with those with improved pain. When we examined the change in protein levels from presurgery to postsurgery and its subsequent risk of worsening or persistent postsurgical pain at 1-year follow-up, we observed increasing levels of Sonic Hedgehog protein from presurgery to postsurgery was associated with a 4-fold increase in the risk of postsurgical pain (odds ratio [quartile 4 vs 1], 3.86 [1.04-14.33]).

CONCLUSION

Using an aptamer-based proteomics platform, we identified plasma proteins and pathways associated with worsening or persistent pelvic pain postsurgical treatment of endometriosis among adolescents and young adults that may aid in risk stratification of individuals with endometriosis.

Altered Monocyte and Lymphocyte Phenotypes Associated with Pathogenesis and Clinical Efficacy of Progestogen Therapy for Peritoneal Endometriosis in Adolescents

Background: Immunological imbalances characteristic of endometriosis may develop as early as the primary manifestations of the disease in adolescence. Objective: To evaluate subpopulation dynamics of monocytes and lymphocytes in peripheral blood and peritoneal fluid of adolescents with peritoneal endometriosis at diagnosis and after 1-year progestogen therapy. Methods: This study included 70 girls, 13-17 years old, diagnosed laparoscopically with peritoneal endometriosis (n = 50, main group) or paramesonephric cysts (n = 20, comparison group). Phenotypes of monocytes and lymphocytes of the blood and macrophages of the peritoneal fluid were analyzed by flow cytometry at diagnosis and during progestogen therapy. Results: Differential blood counts of CD16+ (p < 0.001) and CD86+ (p = 0.017) monocytes were identified as independent risk factors for peritoneal endometriosis in adolescents. During the treatment, cytotoxic lymphocytes CD56dimCD16bright (p = 0.049) and CD206+ monocytes (p < 0.001) significantly increased while CD163+ monocytes decreased in number (p = 0.017). The CD56dimCD16bright blood counts before (p < 0.001) and during progestogen therapy (p = 0.006), as well as CD206+ blood counts during the treatment (p = 0.038), were associated with the efficacy of pain relief after 1-year progestogen therapy. Conclusions: Adolescents with peritoneal endometriosis have altered counts of pro- and anti-inflammatory monocytes and lymphocytes both before and after 1-year progestogen therapy, correlating with treatment efficacy and justifying long-term hormonal therapy.

Effects of the gut microbiota and its metabolite short-chain fatty acids on endometriosis

In recent years, a growing body of research has confirmed that the gut microbiota plays a major role in the maintenance of human health and disease. A gut microbiota imbalance can lead to the development of many diseases, such as pregnancy complications, adverse pregnancy outcomes, polycystic ovary syndrome, endometriosis, and cancer. Short-chain fatty acids are metabolites of specific intestinal bacteria and are crucial for maintaining intestinal homeostasis and regulating metabolism and immunity. Endometriosis is the result of cell proliferation, escape from immune surveillance, and invasive metastasis. There is a strong correlation between the anti-proliferative and anti-inflammatory effects of short-chain fatty acids produced by gut microbes and the development of endometriosis. Given that the mechanism of action of gut microbiota and Short-chain fatty acids in endometriosis remain unclear, this paper aims to provide a comprehensive review of the complex interactions between intestinal flora, short-chain fatty acids and endometriosis. In addition, we explored potential microbial-based treatment strategies for endometriosis, providing new insights into the future development of diagnostic tests and prevention and treatment methods for endometriosis.

Guideline No. 449: Diagnosis and Impact of Endometriosis - A Canadian Guideline

OBJECTIVE

To provide a contemporary approach to the understanding of the impact and methods for the diagnosis of endometriosis in Canada.

TARGET POPULATION

Individuals, families, communities, health care providers, and health care administrators who are affected by, care for patients with, or manage delivery of services for endometriosis.

OPTIONS

The diagnosis of endometriosis is facilitated by a detailed history, examination, and imaging tests with providers who are experienced in endometriosis care. Surgical evaluation with pathology confirms a diagnosis of endometriosis; however, it is not required for those whose diagnosis was confirmed with imaging.

OUTCOMES

There is a need to address earlier recognition of endometriosis to facilitate timely access to care and support. Education directed at the public, affected individuals and families, health care providers, and health care administrators are essential to reduce delays in diagnosis and treatment.

BENEFITS, HARMS, AND COSTS

Increased awareness and education about the impact and approach to diagnosis may support timely access to care for patients and families affected by endometriosis. Earlier and appropriate care may support a reduced health care system burden; however, improved clinical evaluation may require initial investments.

EVIDENCE

Each section was reviewed with a unique search strategy representative of the evidence available in the literature related to the area of focus. The literature searches for each section of this guideline are listed in Appendix A and include information from published systematic reviews described in the text.

VALIDATION METHODS

The recommendations were developed following two rounds of review by a national expert panel through an iterative 2-year consensus process. Further details on the process are shared in Appendix B. The authors rated the quality of evidence and strength of recommendations using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. See Appendix C (Table C1 for definitions and Table C2 for interpretations of strong and conditional recommendations).

INTENDED AUDIENCE

This guideline is intended to support health care providers and policymakers involved in the care of those impacted by endometriosis and the systems required to support them.

Plasma microRNA expression in adolescents and young adults with endometriosis: the importance of hormone use

Introduction

Prior studies have investigated the diagnostic potential of microRNA (miRNA) expression profiles for endometriosis. However, the vast majority of previous studies have only included adult women. Therefore, we sought to investigate differential expression of miRNAs among adolescents and young adults with endometriosis.

Methods

The Women's Health Study: from Adolescence to Adulthood (A2A) is an ongoing WERF EPHect compliant longitudinal cohort. Our analysis included 64 patients with surgically-confirmed endometriosis (96% rASRM stage I/II) and 118 females never diagnosed with endometriosis frequency matched on age (median = 21 years) and hormone use at blood draw. MicroRNA measurement was separated into discovery (10 cases and 10 controls) and internal replication (54 cases and 108 controls) phases. The levels of 754 plasma miRNAs were assayed in the discovery phase using PCR with rigorous internal control measures, with the relative expression of miRNA among cases vs. controls calculated using the 2-ΔΔCt method. miRNAs that were significant in univariate analyses stratified by hormone use were included in the internal replication phase. The internal replication phase was split 2:1 into a training and testing set and utilized FirePlex miRNA assay to assess 63 miRNAs in neural network analyses. The testing set of the validation phase was utilized to calculate the area under the curve (AUC) of the best fit models from the training set including hormone use as a covariate.

Results

In the discovery phase, 49 miRNAs were differentially expressed between endometriosis cases and controls. The associations of the 49 miRNAs differed by hormone use at the time of blood draw. Neural network analysis in the testing set of the internal replication phase determined a final model comprising 5 miRNAs (miR-542-3p, let-7b-3p, miR-548i, miR-769-5p, miR-30c-1-3p), yielding AUC = 0.77 (95% CI: 0.67-0.87, p < 0.001). Sensitivity in the testing dataset improved (83.3% vs. 72.2%) while the specificity decreased (58.3% vs. 72.2%) compared to the training set.

Conclusion

The results suggest that miR-542-3p, let-7b-3p, miR-548i, miR-769-5p, miR-30c-1-3p may be dysregulated among adolescent and young adults with endometriosis. Hormone use was a significant modifier of miRNA dysregulation and should be considered rigorously in miRNA diagnostic studies.

Altered Glycolysis, Mitochondrial Biogenesis, Autophagy and Apoptosis in Peritoneal Endometriosis in Adolescents

Energy metabolism plays a pivotal role in the pathogenesis of endometriosis. For the initial stages of the disease in adolescents, this aspect remains unexplored. The objective of this paper was to analyze the association of cellular and endosomal profiles of markers of glycolysis, mitochondrial biogenesis, apoptosis, autophagy and estrogen signaling in peritoneal endometriosis (PE) in adolescents. We included 60 girls aged 13-17 years in a case-control study: 45 with laparoscopically confirmed PE (main group) and 15 with paramesonephric cysts (comparison group). Samples of plasma and peritoneal fluid exosomes, endometrioid foci and non-affected peritoneum were tested for estrogen receptor (Erα/β), hexokinase (Hex2), pyruvate dehydrogenase kinase (PDK1), glucose transporter (Glut1), monocarboxylate transporters (MCT1 and MCT2), optic atrophy 1 (OPA1, mitochondrial fusion protein), dynamin-related protein 1 (DRP1, mitochondrial fission protein), Bax, Bcl2, Beclin1, Bnip3, P38 mitogen-activated protein kinase (MAPK), hypoxia-inducible factor 1 (Hif-1α), mitochondrial voltage-dependent anion channel (VDAC) and transforming growth factor (TGFβ) proteins as markers of estrogen signaling, glycolysis rates, mitochondrial biogenesis and damage, apoptosis and autophagy (Western-Blot and PCR). The analysis identified higher levels of molecules associated with proliferation (ERβ), glycolysis (MCT2, PDK1, Glut1, Hex2, TGFβ and Hif-1α), mitochondrial biogenesis (OPA1, DRP1) and autophagy (P38, Beclin1 and Bnip3) and decreased levels of apoptosis markers (Bcl2/Bax) in endometrioid foci compared to non-affected peritoneum and that in the comparison group (p < 0.05). Patients with PE had altered profiles of ERβ in plasma and peritoneal fluid exosomes and higher levels of Glut1, MCT2 and Bnip3 in plasma exosomes (p < 0.05). The results of the differential expression profiles indicate microenvironment modification, mitochondrial biogenesis, estrogen reception activation and glycolytic switch along with apoptosis suppression in peritoneal endometrioid foci already in adolescents.

"SO FAR AWAY" How Doctors Can Contribute to Making Endometriosis Hell on Earth. A Call for Humanistic Medicine and Empathetic Practice for Genuine Person-Centered Care. A Narrative Review

"SO FAR AWAY" * How Doctors Can Contribute to Making Endometriosis Hell on Earth [* by Knopfler M. In Dire Straits. Brothers in Arms. Vertigo Records, U.K., 1985].

Abstract

The distance physicians may create within the relationship with their patients by not having a humanistic approach to their practice may strongly influence clinical outcomes. The purpose of this paper is to convey the well-known narrative of patient dissatisfaction into pro-action by discussing the aspects of dehumanization, which may occur in the relationship between physicians and women with endometriosis. Eight dimensions of dehumanization are examined and related to everyday scenarios occurring in endometriosis care settings and the possible downstream consequences on patients' clinical outcomes are described. Objectification, which may come across as minimization of pain, may not only increase patients' perception of pain but also lead to undertreatment of unrecognized forms of endometriosis, especially among adolescents. Passivity, that is not favoring shared decision-making nor self-management, may compromise adherence to treatment, reducing patients' trust in physicians and quality of life. The same consequences may result from homogenization, that is giving for granted that all patients have the same access to care. Both isolation, ie not practicing therapeutic empathy, and loss of meaning, ie not supporting patients in the re-definition of their life plans, may affect women's psychological wellbeing and further increase pain perception. Ignoring women's personal journey by not providing clear information on the consequences endometriosis may have on their lives may favor women's self-silencing. Not promoting an un-biased communication and not setting aside scientific polarization are the main features of dislocation, which may jeopardize patient empowerment. Lastly, having a reductionist approach to the body may contribute to chronicization of pain, thus compromising quality of life. This considered, taking time to listen to women with endometriosis and tailoring decisions on the basis of their individual needs should be fostered as a moral duty. Physicians should always keep in mind that they are not only deliverers of treatment; they are a form of treatment themselves.

Menstrual symptoms and subjective well-being among postmenarchal adolescents

BACKGROUND

Menstrual symptoms are predominantly studied among adults but may occur directly after menarche. Adolescent menstrual healthcare, however, faces specific obstacles and more research into menstrual symptoms as a determinant of adolescent well-being is therefore advocated.

OBJECTIVE

This study aimed to investigate menstrual symptoms and their impact on everyday life and well-being among postmenarchal adolescents.

STUDY DESIGN

A survey was delivered to a random sample of 1644 schoolgirls, drawn from a population-based project involving 116 lower secondary education schools (7th and 8th grade) in Stockholm, Sweden. Menstrual symptoms (ie, dysmenorrhea, heavy bleeding, irregular periods, mood disturbance, other general symptoms) were investigated through multiple choice questions and defined according to their impact on everyday life as mild (seldom affected), moderate (affected but possible to cope) and severe (affected and difficult to cope). Subjective well-being was measured with the World Health Organization Five Well-Being index. Postmenarchal respondents were eligible for analysis; those with incomplete outcome data or using hormonal contraception were excluded. The frequency and severity of symptoms across different postmenarchal years (1st, 2nd, 3rd, 4th, or 5th+ year after menarche) were studied with Chi-square and Kendall's tau statistics. Analysis of variance was used to study the association between menstrual symptoms and World Health Organization Five Well-Being index scores. A composite menstrual health index variable was obtained through principal component analysis and used to study the overall impact of menstrual symptoms on well-being in regression analyses.

RESULTS

Of 1100 postmenarchal girls (mean age, 14.1±0.7 years), 93.2% reported menstrual symptoms, 81.3% had at least 1 moderate symptom and 31.3% had at least 1 severe symptom. The most frequent symptoms were dysmenorrhea (80.4%) and mood disturbance (81.1%), followed by irregular periods (67.9%), heavy bleeding (60.4%), and other general symptoms (60.4%). Throughout postmenarchal years, there was a significant increase in frequency and severity (P<.001) of dysmenorrhea (τ=0.148), heavy bleeding (τ=0.134), mood disturbance (τ=0.117), and other general symptoms (τ=0.110), but not irregular periods (τ=-0.0201; P=.434). Girls with menstrual symptoms had significantly lower World Health Organization Five Well-Being index scores than those without symptoms (mean difference, -17.3; 95% confidence interval, -22.4 to -12.3). Analysis of variance showed significant associations (P<.001) with World Health Organization Five Well-Being index scores for each of the examined menstrual symptoms. In post hoc pairwise comparisons with peers without symptoms, the greatest reductions in World Health Organization Five Well-Being index score were found among girls with severe symptoms (mean difference for: dysmenorrhea, -20.72; heavy bleeding, -15.75; irregular periods, -13.81; mood disturbance, -24.97; other general symptoms, -20.29), but significant differences were observed even for moderate or mild symptoms. The composite menstrual health index was significantly associated with World Health Organization Five Well-Being index scores in regression analysis, independently of age, age at menarche, body mass index, smoking, physical activity, own and parental country of birth, biparental care, and socioeconomic status.

CONCLUSION

Despite growing awareness about the relevance of menstruation to women's health, unmet menstrual health needs are a potential threat to the well-being of adolescents. Education, screening, and clinical competence are important tools to reduce the burden of menstrual symptoms during adolescence and to prevent long-term consequences. The development of novel person-centered strategies should be a priority for clinical practice and research in adolescent menstrual health.

Deep Infiltrating Endometriosis in Adolescence: Early Diagnosis and Possible Prevention of Disease Progression

Endometriosis has a prevalence of 10% worldwide in premenopausal women. Probably, endometriosis begins early in the life of young girls, and it is commonly diagnosed later in life. The prevalence of deep infiltrating endometriosis (DIE) in adolescence is currently unknown due to diagnostic limits and underestimation of clinical symptoms. Dysmenorrhea is a common symptom in adolescents affected by DIE, often accompanied by dyspareunia and chronic acyclic pelvic pain. Ultrasonography-either performed transabdominal, transvaginal or transrectal-should be considered the first-line imaging technique despite the potential for missed diagnosis due to early-stage disease. Magnetic resonance imaging should be preferred in the case of virgo patients or when ultrasonographic exam is not accepted. Diagnostic laparoscopy is deemed acceptable in the case of suspected DIE not responding to conventional hormonal therapy. An early medical and/or surgical treatment may reduce disease progression with an immediate improvement in quality of life and fertility, but at the same time, painful symptoms may persist or even recur due to the surgery itself. The aim of this narrative review is to report the prevalence of DIE in adolescents, describe the pathogenetic theories and discuss the management in adolescent women, including the challenging road to diagnosis and the treatment alternatives.

Pelvic pain symptoms and endometriosis characteristics in relation to oxidative stress among adolescents and adults with and without surgically-confirmed endometriosis

Background: While the majority of reproductive-aged females will experience pelvic pain during their lives, biological mechanisms underlying pelvic pain are not well understood. We investigated associations between pelvic pain symptoms and oxidative stress among people with and without surgically-confirmed endometriosis. Methods: Using an enzyme-linked immunosorbent assay, we measured 8-Hydroxy-2'-deoxyguanosine (8-OHdG) in urine samples and corrected for creatinine levels in 434 surgically-confirmed endometriosis participants compared to 605 participants never diagnosed with endometriosis. At enrollment, participants reported details of their pelvic pain symptoms. Linear regression was used to compute geometric mean (GM) creatinine-corrected 8-OHdG levels with 95% confidence intervals (CI) among all participants and those with and without endometriosis separately, adjusting for potential confounders. Interactions by surgically-confirmed endometriosis status were tested by Wald statistics. Results: No trends in 8-OHdG were observed among those with or without endometriosis for severity or frequency of dysmenorrhea, acyclic pelvic pain, dyspareunia or pain with bowel movements. Among endometriosis participants, lower 8-OHdG levels were observed for participants with any white, blue/black, or brown lesions (GM=76.7 versus 82.9 ng/mg; p=0.10), which was primarily driven by lower levels of 8-OHdG for any blue/black lesions (GM=72.8 versus 81.6 ng/mg; p=0.05). Conclusion: While no associations were observed between 8-OHdG and pelvic pain symptoms, future research is needed to assess how other pathways of oxidative damage, e.g. through proteins or lipids, may affect endometriosis-associated symptoms. Additionally, further research is needed to understand differences in oxidative stress among endometriosis lesion sub-phenotypes.

Differences in characteristics and use of complementary and alternative methods for coping with endometriosis-associated acyclic pelvic pain across adolescence and adulthood

Introduction

Over four million women in the US alone have been diagnosed with endometriosis. For those living with this disease, surgery and hormonal treatment reduce associated pelvic pain in some, while others continue to experience life impacting pain. Therefore, identification of accessible and cost-effective methods of pain reduction to compliment current treatment is urgently needed. Our objective was to quantify the prevalence of complementary and alternative methods used to manage acyclic pelvic pain and their reported benefit among women of different age groups living with endometriosis.

Methods

We used baseline questionnaire data from laparoscopically-confirmed endometriosis cases who completed a WERF EPHect compliant questionnaire in the longitudinal cohort of The Women's Health Study: From Adolescence to Adulthood (A2A). Participants with acyclic pelvic pain were asked to indicate specific methods or activities that either helped or worsened their pelvic/lower abdominal pain. Differences among age groups [adolescent (<18 years), young adult (18-25 years), and adult (>25 years)] were assessed using Fisher's exact test.

Results

Of the 357 participants included in analysis, sleep for coping was reported more frequently among adolescents (n = 59, 57.3%) compared to young adults (n = 40, 44.0%) and adults (n = 19, 31.1%; p = 0.004). Adolescents also reported more frequent use of music (n = 29, 21.2%) than young adults (n = 10, 7.0%) and adults (n = 7, 9.1%; p = 0.001). Exercise worsened pain most commonly among adolescents (n = 82, 59.9%), followed by younger adults (n = 67, 46.9%), and adults (n = 27, 35.1%; p = 0.002).

Discussion

Our analysis of participants in the A2A cohort showed that the prevalence of complementary and alternative methods used for coping with endometriosis-associated acyclic pelvic pain varied by age group. Future studies should aim to provide information that will further inform decisions in making care plans for managing endometriosis-associated pain that is effective, accessible, and tailored to the preferences of the patient.

Proposal for targeted, neo-evolutionary-oriented secondary prevention of early-onset endometriosis and adenomyosis. Part II: medical interventions

According to consistent epidemiological data, the slope of the incidence curve of endometriosis rises rapidly and sharply around the age of 25 years. The delay in diagnosis is generally reported to be between 5 and 8 years in adult women, but it appears to be over 10 years in adolescents. If this is true, the actual onset of endometriosis in many young women would be chronologically placed in the early postmenarchal years. Ovulation and menstruation are inflammatory events that, when occurring repeatedly for years, may theoretically favour the early development of endometriosis and adenomyosis. Moreover, repeated acute dysmenorrhoea episodes after menarche may not only be an indicator of ensuing endometriosis or adenomyosis, but may also promote the transition from acute to chronic pelvic pain through central sensitization mechanisms, as well as the onset of chronic overlapping pain conditions. Therefore, secondary prevention aimed at reducing suffering, limiting lesion progression, and preserving future reproductive potential should be focused on the age group that could benefit most from the intervention, i.e. severely symptomatic adolescents. Early-onset endometriosis and adenomyosis should be promptly suspected even when physical and ultrasound findings are negative, and long-term ovulatory suppression may be established until conception seeking. As nowadays this could mean using hormonal therapies for several years, drug safety evaluation is crucial. In adolescents without recognized major contraindications to oestrogens, the use of very low-dose combined oral contraceptives is associated with a marginal increase in the individual absolute risk of thromboembolic events. Oral contraceptives containing oestradiol instead of ethinyl oestradiol may further limit such risk. Oral, subcutaneous, and intramuscular progestogens do not increase the thromboembolic risk, but may interfere with attainment of peak bone mass in young women. Levonorgestrel-releasing intra-uterine devices may be a safe alternative for adolescents, as amenorrhoea is frequently induced without suppression of the ovarian activity. With regard to oncological risk, the net effect of long-term oestrogen-progestogen combinations use is a small reduction in overall cancer risk. Whether surgery should be considered the first-line approach in young women with chronic pelvic pain symptoms seems questionable. Especially when large endometriomas or infiltrating lesions are not detected at pelvic imaging, laparoscopy should be reserved to adolescents who refuse hormonal treatments or in whom first-line medications are not effective, not tolerated, or contraindicated. Diagnostic and therapeutic algorithms, including self-reported outcome measures, for young individuals with a clinical suspicion of early-onset endometriosis or adenomyosis are proposed.

Evaluation and Management of Endometriosis in the Adolescent

Endometriosis is a chronic condition, with debilitating symptoms affecting all ages. Dysmenorrhea and pelvic pain often begin in adolescence, affecting school, daily activities, and relationships. Despite the profound burden of endometriosis, many adolescents experience suboptimal management and significant delay in diagnosis. The symptomatology and laparoscopic findings of endometriosis in adolescents are often different than in adults, and the medical and surgical treatments for adolescents may differ from those for adults as well. This Narrative Review summarizes the diagnosis, evaluation, and management of endometriosis in adolescents. Given the unique challenges and complexities associated with diagnosing endometriosis in this age group, it is crucial to maintain a heightened level of suspicion and to remain vigilant for signs and symptoms. By maintaining this lower threshold for consideration, we can ensure timely and accurate diagnosis, enabling early intervention and improved management in our adolescent patients.

Epidemiology of endometriosis in Ukraine: results a multicenter study (2019-2021)

OBJECTIVE

Aim: To estimate the prevalence and incidence of endometriosis, and to evaluate risk factors associated with endometriosis in Ukraine.

PATIENTS AND METHODS

Materials and Methods: The multicenter cohort study was performed partly as a cross-sectional study to estimate occurrence of endometriosis, partly as a case-control study to look for factors associated with endometriosis. The study was carried out during the period from January 1st, 2019 to December 31st, 2021.This study included adolescent girls and adult women from 15 Ukrainian regions.

RESULTS

Results: Among 15,458 patients, 4,397 (28.4%) endometriosis were observed. Of all endometriosis cases, 48.5% were peritoneal/superf i cial endometriosis (SPE), 34.6% were ovarian endometriotic cyst/endometrioma (OMA), and 16.9% were deep inf i ltrating endometriosis (DIE). The prevalence of the three types of endometriosis was: SPE, 13.8%; OMA, 9.8%; and DIE, 4.8%. The factors associated with an increased risk for endometriosis include age 23-32 years, parity (small number of births), age of fi rst sexual intercourse <20 years, history of healthcare-associated infection after gynecological surgery (pelvic abscess or cellulitis, salpingitis and oophoritis), history of infertility, early menarche (before the age of 11), dysmenorrhea, dyspareunia, pelvic pain, intermenstrual bleeding, heavy uterine bleeding and dysmenorrhea, and heavy uterine bleeding.

CONCLUSION

Conclusions: Endometriosis is a common gynecological disease in Ukraine and the relative frequency of dif f erent types of endometriosis: the most common were ovarian and peritoneal endometriosis. Healthcare services and public health strategies need to be strengthened to ensure timely endometriosis diagnosis in adolescent girls and adult women and treatment.

Gut Microbiota and Endometriosis: Exploring the Relationship and Therapeutic Implications

Endometriosis is a common inflammatory disease affecting women of reproductive age, characterized by the growth of endometrial tissue beyond the uterus. In addition to gynecological manifestations, many endometriosis patients experience gastrointestinal symptoms, indicating a potential association between gut health and the disease. Recent studies have revealed alterations in the gut microbiota of individuals with endometriosis, including reduced diversity, microbial composition imbalances, and pathogenic bacteria. These changes can disrupt immune function, increase inflammation, and contribute to the chronic inflammatory state observed in endometriosis. Moreover, dysregulation of intestinal permeability may further exacerbate gastrointestinal symptoms in affected individuals. Understanding the role of the gut microbiota and intestinal permeability in endometriosis can provide valuable insights into disease pathogenesis, aid in non-invasive diagnostic approaches, and open new avenues for therapeutic interventions. Probiotics, in particular, have shown promise in improving endometriosis-associated pain symptoms and reducing endometriotic lesions in animal models. This review suggests that additional research and well-designed clinical trials are necessary to validate the potential diagnostic and therapeutic benefits of manipulating the gut microbiota in managing endometriosis and its gastrointestinal symptoms, thereby improving the quality of life for those affected.

Endometriosis and Adolescence: The Impact of Dysmenorrhea

Endometriosis affects approximately 10% of premenopausal women worldwide. Despite its impact on quality of life, the delay in diagnosing this chronic disease is well known. Many patients with endometriosis report having suffered from dysmenorrhea and chronic pelvic pain in adolescence or at a young age. However, this painful symptom is often highly underestimated and considered a normal and transient symptom in young women. The real prevalence of endometriosis in adolescence remains uncertain. Some authors recently described at least one ultrasound feature of endometriosis in 13.3% of a general population of adolescent girls, which increased to 35.3% in young girls with severe dysmenorrhea. Dysmenorrhea is classified as primary dysmenorrhea or secondary dysmenorrhea. Primary dysmenorrhea is defined as a menstrual pain without organic disease, while secondary dysmenorrhea is defined as a menstrual pain associated with organic pelvic pathology. Since endometriosis represents the main cause of secondary dysmenorrhea in adolescents and young women, it is important to determine whether the patient has primary dysmenorrhea or additional suggestive symptoms related to endometriosis. Endometriosis in adolescent patients is a challenging problem with clinical and pathological differences compared with its presentation in premenopausal women. Adolescents and young women with dysmenorrhea and painful symptoms that suggest endometriosis should be referred to dedicated endometriosis centers for an early diagnosis and appropriate medical and surgical management. This paper aims to describe the role of dysmenorrhea in adolescents and the management of these young patients to confirm or exclude endometriosis.

How to Manage Endometriosis in Adolescence: The Endometriosis Treatment Italian Club Approach

The evaluation of endometriosis in an adolescent girl is a challenging topic. The initial stage of the disease and the limited diagnostic instrument appropriate for the youth age and for its typical features can reduce the ability of the gynecologist. At the same time, missing a prompt diagnosis can delay the beginning of specific and punctual management of endometriosis, which could avoid a postponed diagnosis from 6 to 12 years, typical of adolescent girls complaining of dysmenorrhea. This article aimed to answer all the potential questions around the diagnosis and management of endometriosis in adolescents starting from a clinical case looking at the possible solution that is easily reproducible in the clinical practice.

Plasma proteomic profiles of pain subtypes in adolescents and young adults with endometriosis

STUDY QUESTION

What are the similarities and differences in the systemic proteomic profiles by endometriosis-associated pain subtypes among adolescents and young adults with endometriosis?

SUMMARY ANSWER

Endometriosis-associated pain subtypes exhibited distinct plasma proteomic profiles.

WHAT IS KNOWN ALREADY

Endometriosis patients, especially those diagnosed in adolescents and young adults, are often plagued by various pain symptoms. However, it is not clear what biological processes underlie this heterogeneity.

STUDY DESIGN, SIZE, DURATION

We conducted a cross-sectional analysis using data and plasma samples from 142 adolescent or young adult participants of the Women's Health Study: From Adolescence to Adulthood cohort with laparoscopically confirmed endometriosis.

PARTICIPANTS/MATERIALS, SETTING, METHODS

We measured 1305 plasma protein levels by SomaScan. We classified self-reported endometriosis-associated pain into subtypes of dysmenorrhea, acyclic pelvic pain, life impacting pelvic pain, bladder pain, bowel pain, and widespread pain phenotype. We used logistic regression to calculate the odds ratios and 95% confidence intervals for differentially expressed proteins, adjusting for age, BMI, fasting status, and hormone use at blood draw. Ingenuity Pathway Analysis identified enriched biological pathways.

MAIN RESULTS AND THE ROLE OF CHANCE

Our study population consisted mainly of adolescents and young adults (mean age at blood draw = 18 years), with nearly all (97%) scored as rASRM stage I/II at laparoscopic diagnosis of endometriosis, which is a common clinical presentation of endometriosis diagnosed at a younger age. Pain subtypes exhibited distinct plasma proteomic profiles. Multiple cell movement pathways were downregulated in cases with severe dysmenorrhea and life impacting pelvic pain compared to those without (P < 7.5×10-15). Endometriosis cases with acyclic pelvic pain had upregulation of immune cell adhesion pathways (P < 9.0×10-9), while those with bladder pain had upregulation of immune cell migration (P < 3.7×10-8) and those with bowel pain had downregulation (P < 6.5×10-7) of the immune cell migration pathways compared to those without. Having a wide-spread pain phenotype involved downregulation of multiple immune pathways (P < 8.0×10-10).

LIMITATIONS, REASONS FOR CAUTION

Our study was limited by the lack of an independent validation cohort. We were also only able to explore any presence of a pain subtype and could not evaluate multiple combinations by pain subtypes. Further mechanistic studies are warranted to elucidate the differences in pathophysiology by endometriosis-pain subtype.

WIDER IMPLICATIONS OF THE FINDINGS

The observed variation in plasma protein profiles by pain subtypes suggests different underlying molecular mechanisms, highlighting the need for potential consideration of pain subtypes for effectively treating endometriosis patients presenting with various pain symptoms.

Long-Term Follow-Up Result of Connective Tissue Manipulation in Young Women with Primary Dysmenorrhea: Different Intervention Durations

The purpose of this study was to reveal the effect of connective tissue manipulation (CTM) on long-term pain severity, fatigue, sleep quality, premenstrual symptom severity, general health status, anxiety, and depression in women with primary dysmenorrhea (PD). Thirty-five women with PD were divided into two groups. CTM was applied to the participants in each group on the days when they were not on menstruation between two menstrual cycles for the group 1 (n=18) and between three menstrual cycles for the group 2 (n=17). Intensity of menstrual pain, the sleep quality, and fatigue status of the participants during dysmenorrhea were evaluated by the Visual Analog Scale (VAS). Depressive symptoms and anxiety were evaluated using the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI), respectively. Also, the Premenstrual Syndrome Scale (PMSS) and the General Health Questionnaire (GHQ) were used to investigate the severity of premenstrual symptoms and mental health status during menstrual period. A significant decrease in the pain severity and fatigue of the participants was observed in both group 1 and group 2 after treatment, after 3rd, and 6th month follow-up (p=0.001). Also, this decrease lasted for 12th month follow-up after treatment in group 2 (p=0.0001). There was no statistically significant improvement in sleep quality within each group (p>0.05). Moreover, none of the parameters were significantly different between two groups (p>0.05). We can suggest that 2-cycle CTM treatment should be preferred in clinical settings to obtain long-lasting effects for decreasing pain, fatigue, and premenstrual symptoms in women with PD. CLINICAL TRIAL NUMBER: NCT04509934. Registration date: 8 November 2020.

Exploring Patient Adherence to Post-Surgical Follow-Up in Pelvic Endometriosis

Endometriosis is a significant cause of disability that affects 5-10% of reproductive-aged women. Laparoscopy with histological confirmation is the gold standard in establishing the diagnosis as therapeutic management surgery is addressed to a certain category of patients. The objective of this study was to assess patient adherence to follow-up after surgery for endometriosis as the primary endpoint, pain symptoms, quality of life, mental health, and fertility as the secondary endpoints. We have analyzed patients' adherence to follow-up after surgery for endometriosis after 1, 3, 5, and 7 years. Out of the 2538 total number of surgeries, 453 patients replied just to the first questionnaire (group A), 528 to the first and second (group B), and only 356 carried out the entire follow-up schedule. General health was significantly lower for group A (46.6 vs. 56.4) but with no statistical difference in the post-surgical improvement in both groups. Pain level score improvement was lower for group A (10.5 vs. 18.8), which is statistically significant. In this light, laparoscopy still remains the gold standard in diagnosis only. Furthermore, no malignancy was discovered. The mental component was improved by laparoscopy based on SF-36 in group B. Studies on patient preference for surgery versus alternative treatment are needed.

Endometriosis and the Temporomandibular Joint-Preliminary Observations

(1) Background: The complete picture of the disease is not fully recognized and extends far beyond the pelvis. The disease's impacts lead to systemic inflammation, in turn resulting in sensitization to pain. The aim of this study was to check whether statistical correlations exist in women with endometriosis with regard to their experience of pain: headache, pelvic pain, temporomandibular joint pain, along with teeth clenching and the treatment of the disease. We constructed contingency tables, followed by Pearson's chi-square test and Cramer's V coefficient values. (2) Methods: A survey was conducted among 128 women aged 33.43 ± 5.79 with a diagnosis of endometriosis (disease duration 6.40 ± 5.88 years). (3) Results: There was a correlation between the occurrence of pain on the right and left sides of the pelvis and pain on the right and left sides of the temporomandibular joint, p-value = 0.0397, V = 0.2350, and between the presence of pelvic pain and the treatment of endometriosis, p-value = 0.0104, V = 0.3709, and between the presence of pain outside the pelvis and the treatment of endometriosis, p-value = 0.0311, V = 0.4549. There was a highly significant correlation between teeth clenching and temporomandibular joint pain, p-value = 0.0005, V = 0.3695. (4) Conclusions: The study revealed a correlation between pelvic endometriosis symptoms and symptoms in the temporomandibular joint.

Trends in pelvic pain symptoms over 2 years of follow-up among adolescents and young adults with and without endometriosis

ABSTRACT

We described trends in pelvic pain characteristics over 2 years of follow-up among adolescents and adults with and without endometriosis participating in the longitudinal observational cohort of the Women's Health Study: From Adolescence to Adulthood, using data reported at baseline and at years 1 and 2 of follow-up. Participants completed a questionnaire at baseline (between November 2012 and May 2019) and annually thereafter that included validated measures of severity, frequency, and life interference of dysmenorrhea, acyclic pelvic pain, and dyspareunia. Our study population included 620 participants with surgically confirmed endometriosis (rASRM stage I/II = 95%) and 671 community-based and hospital-based controls, with median age = 19 and 24 years, respectively. The proportion reporting hormone use varied across the 3 years ranging from 88% to 92% for cases and 56% to 58% for controls. At baseline, endometriosis cases were more likely to report severe, frequent, and life-interfering dysmenorrhea, acyclic pelvic pain, and dyspareunia compared with controls. Among cases, frequency and severity of dysmenorrhea and dyspareunia were relatively static across 2 years. However, acyclic pelvic pain improved. Severe acyclic pain decreased from 69% at baseline to 46% at year 2. Daily pain decreased from 28% to 14%, and life interference from 68% to 38%. Trends among controls remained fairly stable across 2 years. Among endometriosis cases who completed the questionnaire at all 3 time points, 18% reported persistent, severe acyclic pelvic pain at all 3 time points. Over time, different trends were observed by pelvic pain type among endometriosis cases and controls, supporting the importance of assessing multidimensional features of pelvic pain.

Early noninvasive diagnosis of endometriosis: dysmenorrhea and specific ultrasound findings are important indicators in young women

OBJECTIVES

To diagnose endometriosis in young patients ≤25y with severe dysmenorrhea through specific ultrasonographic examination findings and to correlate the symptoms to its different forms: ovarian, deep infiltrating endometriosis, and adenomyosis.

DESIGN

A retrospective observational study.

SETTING

University Hospital.

PATIENT(S)

Women aged 12-25 years with severe dysmenorrhea and a visual analog scale score ≥7.

INTERVENTION(S)

This study included 371 women aged 12-25 years referred to our gynecological ultrasound (US) Unit between January 2016 and December 2021 with severe dysmenorrhea and a visual analog scale score ≥7. Two dimensional, 3 dimensional, and power Doppler US pelvic examinations (transvaginal or transrectal in presexually active girls) were performed on all patients. Medical history and symptoms were collected routinely for each patient before the scan.

MAIN OUTCOME MEASURE(S)

All possible locations of endometriosis, isolated or combined occurrence, were evaluated, and recorded using an US dedicated mapping sheet. Painful symptoms were evaluated by visual analog scale and correlated to the different endometriosis forms.

RESULT(S)

At least one US endometriosis feature was identified in 131 (35.3%) patients, whereas the US findings of 170 (45.8%) were normal despite the referred dysmenorrhea. Of the 131 patients with endometriosis, ovarian endometrioma was found in 54 (41.2%), and 22 (16.8%) had an isolated endometrioma. Adenomyosis was detected in 67 (51.1%) patients, and 28 (21.4%) showed its isolated indications. Posterior deep infiltrating endometriosis was found in 70 (53.4%) patients, and uterosacral ligament (USL) fibrotic thickening was found in 63 (48.1%). In 23 patients, the USL lesion was completely isolated. The combined occurrence of dysmenorrhea with dyspareunia, bowel symptoms, and heavy menstrual bleeding increases the presence of endometriosis up to 59%, 63%, and 45%, respectively.

CONCLUSION(S)

In young patients with severe dysmenorrhea, the US-based detection rate of pelvic endometriosis was one-third. USL fibrotic thickening and mild adenomyosis are often the only findings, so an accurate pelvic US scan can provide an early diagnosis by identifying small endometriotic lesions. Young patients with dysmenorrhea should be referred to an expert sonographer to minimize the delay between the onset of symptoms and diagnosis.

Endometriosis in Adolescents: Diagnostics, Clinical and Laparoscopic Features

BACKGROUND

The early diagnosis of endometriosis in adolescents is not developed.

OBJECTIVE

We aim to conduct clinical, imaging, laparoscopic and histological analyses of peritoneal endometriosis (PE) in adolescents in order to improve early diagnosis.

METHODS

In total, 134 girls (from menarche to 17 years old) were included in a case-control study: 90 with laparoscopically (LS) confirmed PE, 44 healthy controls underwent full examination and LS was analyzed in the PE group.

RESULTS

Patients with PE were characterized with heredity for endometriosis, persistent dysmenorrhea, decreased daily activity, gastrointestinal symptoms, higher LH, estradiol, prolactin and Ca-125 (<0.05 for each). Ultrasound detected PE in 3.3% and MRI in 78.9%. The most essential MRI signs are as follows: hypointense foci, the heterogeneity of the pelvic tissue (paraovarian, parametrial and rectouterine pouch) and sacro-uterine ligaments lesions (<0.05 for each). Adolescents with PE mostly exhibit initial rASRM stages. Red implants correlated with the rASRM score, and sheer implants correlated with pain (VAS score) (<0.05). In 32.2%, foci consisted of fibrous, adipose and muscle tissue; black lesions were more likely to be histologically verified (0.001).

CONCLUSION

Adolescents exhibit mostly initial PE stages, which are associated with greater pain. Persistent dysmenorrhea and detected MRI parameters predict the laparoscopic confirmation of initial PE in adolescents in 84.3% (OR 15.4; <0.01), justifying the early surgical diagnostics and shortening the time delay and suffering of the young patients.

Exploring the interface between adolescent dysmenorrhoea and endometriosis: a protocol for a cohort and nested case-control study within the QResearch Database

INTRODUCTION

Dysmenorrhoea affects up to 70%-91% of adolescents who menstruate, with approximately one-third experiencing severe symptoms with impacts on education, work and leisure. Dysmenorrhoea can occur without identifiable pathology, but can indicate underlying conditions, including congenital genital tract anomalies or endometriosis. There is a need for evidence about the management and incidence of dysmenorrhoea in primary care, the impact of treatments in adolescence on long-term outcomes and when to consider the possibility of endometriosis in adolescence.

METHODS AND ANALYSIS

This study aims to improve the evidence base for adolescents presenting to primary care with dysmenorrhoea. It comprises three interlinked studies. Using the QResearch Database, the study population includes all female at birth participants aged 10-19 years any time between 1 January 2000 and 30 June 2021. We will undertake (1) a descriptive study documenting the prevalence of coded dysmenorrhoea in primary care, stratified by demographic variables, reported using descriptive statistics; (2) a prospective open cohort study following an index cohort of all adolescents recorded as attending primary care with dysmenorrhoea and a comparator cohort of five times as many who have not, to determine the HR for a diagnosis of endometriosis, adenomyosis, ongoing menstrual pain or subfertility (considered singly and in combination) anytime during the study period; and (3) a nested case-control study for adolescents diagnosed with endometriosis, using conditional logistic regression, to determine the OR for symptom(s) preceding this diagnosis.

ETHICS AND DISSEMINATION

The project has been independently peer reviewed and received ethics approval from the QResearch Scientific Board (reference OX46 under REC 18/EM/0400).In addition to publication in peer-reviewed academic journals, we will use the combined findings to generate a resource and infographic to support shared decision-making about dysmenorrhoea in community health settings. Additionally, the findings will be used to inform a subsequent qualitative study, exploring adolescents' experiences of menstrual pain.

Gastroenterologist Primer: Endometriosis for Gastroenterologists

BACKGROUND AND AIM

A comprehensive understanding of endometriosis and its common gastrointestinal presentations are critical for gastroenterologists to ensure appropriate and timely screening and diagnosis. Endometriosis is a common inflammatory disease that frequently presents with gastrointestinal symptoms overlapping with irritable bowel syndrome (IBS) and other gastrointestinal disorders. Many endometriosis patients first present to a gastroenterologist or generalist, which may prolong the time to diagnosis and appropriate care.

METHOD AND RESULTS

This review describes the current literature on endometriosis presentation, overlap with gastrointestinal conditions, and standard diagnostic and treatment options for gastroenterologists to consider. For appropriate and swift treatment, gastroenterologists must consider an endometriosis diagnosis in females of menstruating age presenting with pain, bloating, altered stools, and non-gastrointestinal symptoms and refer patients for further evaluation.

Identification of early symptoms of endometriosis through the analysis of online social networks: A social media study

Objective

Endometriosis is a complex full-body inflammation disease with an average time to diagnosis of 7-10 years. Social networks give opportunity to patient to openly discuss about their condition, share experiences, and seek advice. Thus, data from social media may provide insightful data about patient's experience. This study aimed at applying a text-mining approach to online social networks in order to identify early signs associated with endometriosis.

Methods

An automated exploration technique of online forums was performed to extract posts. After a cleaning step of the built corpus, we retrieved all symptoms evoked by women, and connected them to the MedDRA dictionary. Then, temporal markers allowed targeting only the earliest symptoms. The latter were those evoked near a marker of precocity. A co-occurrence approach was further applied to better account for the context of evocations.

Results

Results were visualised using the graph-oriented database Neo4j. We collected 7148 discussions threads and 78,905 posts from 10 French forums. We extracted 41 groups of contextualised symptoms, including 20 groups of early symptoms associated with endometriosis. Among these groups of early symptoms, 13 were found to portray already known signs of endometriosis. The remaining 7 clusters of early symptoms were limb oedema, muscle pain, neuralgia, haematuria, vaginal itching, altered general condition (i.e. dizziness, fatigue, nausea) and hot flush.

Conclusion

We pointed out some additional symptoms of endometriosis qualified as early symptoms, which can serve as a screening tool for prevention and/or treatment purpose. The present findings offer an opportunity for further exploration of early biological processes triggering this disease.

Physiotherapy Management in Endometriosis

Endometriosis is a disease whose underlying cause is the growth of the endometrium outside the uterine cavity. The disease is characterised by unpleasant pain in the pelvic region, irrespective of the phase of the woman's cycle. Physiotherapy in its various forms can be an excellent complement to the gynaecological treatment of endometriosis, by virtue of reducing inflammation, alleviating pain and thus significantly improving women's quality of life. Physiotherapy in endometriosis should include kinesiotherapy, manual therapy including visceral therapy, physical therapy, spa treatment including balneotherapy, and hydrotherapy. The aim of this study is to present the use of physiotherapy as an adjunct therapy in the treatment of endometriosis. A review of the available literature in the Medline, PubMed and Google Scholar databases was performed without being limited by the time frame of available publications on the forms of physiotherapy used in the treatment of endometriosis.

Health-related quality of life in endometriosis: The influence of endometriosis-related symptom presence and distress

This international cross-sectional study examined the relationships between endometriosis-related symptom experience and health-related quality of life (HRQoL) in 318 women with endometriosis. Measures of symptom burden and distress, pain, psychological wellbeing, and HRQoL were collected via an online survey. Age, symptom duration, burden, and distress were associated with lower psychological wellbeing and HRQoL, with small to medium effect sizes. Somatic concern, depression, pain, dysmenorrhea, clitoral pain, dyspareunia, and bloating were found to be significant correlates of HRQoL. The findings highlight the importance of considering a broader range of endometriosis-related symptoms than pain alone and the ongoing need to reduce diagnostic delay in endometriosis.

Impact of Pelvic Floor Physical Therapy on Function in Adolescents and Young Adults with Biopsy-Confirmed Endometriosis at a Tertiary Children's Hospital: A Case Series

STUDY OBJECTIVE

The purpose of this case series is to describe the change in capability to perform self-selected activities in adolescent and young adult patients with chronic pelvic pain and surgically proven endometriosis following pelvic floor physical therapy as part of multidisciplinary treatment.

DESIGN

Retrospective case series SETTING: Tertiary care pediatric hospital PARTICIPANTS: Twenty patients with ages ranging from 14 to 22 years and a median age of 16.5 years with biopsy-confirmed endometriosis INTERVENTION: Pelvic floor physical therapy MAIN OUTCOME MEASURE(S): Patient-Specific Functional Scale (PSFS) outcome measure RESULTS: Patients had a clinically significant functional improvement (median score of 6.0 points on the PSFS outcome measure; interquartile range, 3.8-13.5) over the course of care (median number of 12 visits; range 4-48 visits) (P < .001).

CONCLUSIONS

Patients with chronic pelvic pain and surgically proven endometriosis experienced significant functional improvement after physical therapy treatment. The results of this case series suggest that physical therapy is a viable additional intervention for adolescents and young adults with chronic pelvic pain and endometriosis and warrants further research.

Pathophysiology, diagnosis, and management of endometriosis

Endometriosis affects approximately 190 million women and people assigned female at birth worldwide. It is a chronic, inflammatory, gynecologic disease marked by the presence of endometrial-like tissue outside the uterus, which in many patients is associated with debilitating painful symptoms. Patients with endometriosis are also at greater risk of infertility, emergence of fatigue, multisite pain, and other comorbidities. Thus, endometriosis is best understood as a condition with variable presentation and effects at multiple life stages. A long diagnostic delay after symptom onset is common, and persistence and recurrence of symptoms despite treatment is common. This review discusses the potential genetic, hormonal, and immunologic factors that lead to endometriosis, with a focus on current diagnostic and management strategies for gynecologists, general practitioners, and clinicians specializing in conditions for which patients with endometriosis are at higher risk. It examines evidence supporting the different surgical, pharmacologic, and non-pharmacologic approaches to treating patients with endometriosis and presents an easy to adopt step-by-step management strategy. As endometriosis is a multisystem disease, patients with the condition should ideally be offered a personalized, multimodal, interdisciplinary treatment approach. A priority for future discovery is determining clinically informative sub-classifications of endometriosis that predict prognosis and enhance treatment prioritization.

The Role of Visceral Therapy in the Sexual Health of Women with Endometriosis during the COVID-19 Pandemic: A Literature Review

Patients with endometriosis had limited possibilities for contemporary diagnosis and treatment during the SARS-CoV-2 (COVID-19) pandemic. Surgeries that may have eliminated pain or restored fertility were postponed. Endometriosis may affect the vagina, peritoneum, bladder, or other organs outside the pelvis and impact women's sexual health, especially during pandemics. Holistic care of patients is crucial to improving their lives and sexual health. A scoping review was conducted to analyze the relevant literature in light of our experience in gynecology and physiotherapy during the COVID-19 pandemic.

Endometriosis and Cannabis Consumption During the COVID-19 Pandemic: An International Cross-Sectional Survey

Introduction: Endometriosis affects 1 in 10 women worldwide, with most experiencing difficulties achieving adequate symptom control. These difficulties have been compounded by the onset of the COVID-19 pandemic due to worldwide shifts in health care resource allocation. As cannabis is a relatively common form of self-management in endometriosis, this study aims to explore the impact of the COVID-19 pandemic on cannabis consumption in those with endometriosis. Methods: An anonymous, cross-sectional online international survey was developed and promoted by endometriosis advocacy/support organizations worldwide. Respondents needed to have a diagnosis of endometriosis and be aged between 18 and 55. Results: A total of 1634 responses were received from 46 different countries. The average age of respondents was 30, with a mean diagnosis age of 25. Eight hundred forty-six respondents (51%) reported consuming cannabis in the past 3 months, with 55% of these reporting use for symptom management only. One in five respondents (20%) reported having consumed cannabis previously, the most common reason for discontinuation (65%) was access difficulties during COVID. Those who had legal access were more likely to consume cannabis than those without (p<0.0001) and were more likely to disclose usage to health care professionals (p<0.0001). The most common reasons for consuming cannabis during COVID was increased stress/anxiety (59%) and lack of access to normal medical care (48%). Pre-pandemic, cannabis was mostly consumed at least once a day (61%) and in inhaled forms (51.6%). Consumption increased for most people (57%) during the pandemic. During the pandemic just under a quarter (23%) of respondents changed their mode of consumption, with a reduction in inhaled forms (39.5%) and an increase in consumption of edibles (40%) or oil (25.2%). Conclusions: Cannabis consumption, especially for symptom relief, was relatively common among those with endometriosis, with some people starting their consumption of cannabis due to health care restrictions that occurred due to the COVID-19 pandemic. Difficulties accessing cannabis and unpleasant/unwanted side effects were the most common reasons for lack of current cannabis consumption in those who had previously consumed it. Cannabis consumption may form an important part of endometriosis management especially when access to routine medical care is restricted.
