Characteristics of women with endometriosis from the USA and Puerto Rico

Multicenter evaluation of blood-based biomarkers for the detection of endometriosis and adenomyosis: A prospective non-interventional study

OBJECTIVE

To evaluate blood-based biomarkers to detect endometriosis and/or adenomyosis across nine European centers (June 2014-April 2018).

METHODS

This prospective, non-interventional study assessed the diagnostic accuracy of 54 blood-based biomarker immunoassays in samples from 919 women (aged 18-45 years) with suspicion of endometriosis and/or adenomyosis versus symptomatic controls. Endometriosis was stratified by revised American Society for Reproductive Medicine stage. Symptomatic controls were "pathologic symptomatic controls" or "pathology-free symptomatic controls". The main outcome measure was receiver operating characteristic-area under the curve (ROC-AUC) and Wilcoxon P values corrected for multiple testing (q values).

RESULTS

CA-125 performed best in "all endometriosis cases" versus "all symptomatic controls" (AUC 0.645, 95% confidence interval [CI] 0.600-0.690, q < 0.001) and increased (P < 0.001) with disease stage. In "all endometriosis cases" versus "pathology-free symptomatic controls", S100-A12 performed best (AUC 0.692, 95% CI 0.614-0.769, q = 0.001) followed by CA-125 (AUC 0.649, 95% CI 0.569-0.729, q = 0.021). In "adenomyosis only cases" versus "symptomatic controls" or "pathology-free symptomatic controls", respectively, the top-performing biomarkers were sFRP-4 (AUC 0.615, 95% CI 0.551-0.678, q = 0.045) and S100-A12 (AUC 0.701, 95% CI 0.611-0.792, q = 0.004).

CONCLUSION

This study concluded that no biomarkers tested could diagnose or rule out endometriosis/adenomyosis with high certainty.

Patient experiences of endometriosis diagnosis: A mixed methods approach

OBJECTIVE

To examine patient-described experiences of endometriosis diagnosis.

DESIGN

Mixed-methods study.

SETTING

Online patient-led endometriosis support groups.

POPULATION OR SAMPLE

People with endometriosis aged over 18.

METHODS

A survey with qualitative and quantitative questions was distributed through online patient-led endometriosis support groups. Descriptive statistics were used to analyse quantitative data, and thematic analysis was used for qualitative responses. Quantitative and qualitative data were triangulated to examine patient experiences of endometriosis diagnosis across age groups.

MAIN OUTCOME MEASURES

Experiences of endometriosis diagnosis among people with endometriosis.

RESULTS

A total of 2017 people with endometriosis from 63 countries responded to the questionnaire. Patients experienced an average delay of 3.7 years between symptom onset and first presentation of symptoms to a physician (the care-seeking delay) and an average delay of 5.8 years between first presentation of symptoms to a physician and diagnosis of endometriosis (the healthcare-related delay). Patients experienced an average total diagnostic delay of 9.6 years. Participants aged over 35 at the time of the study reported significantly longer times to receive an endometriosis diagnosis (mean 10.7, 95% confidence interval [CI] 10.2-11.2) compared with participants age 18-24 (6.8, 95% CI 6.1-7.5 years). The qualitative analysis identified the following themes: physicians normalised endometriosis symptoms, patients felt their symptoms were ignored by physicians because they were considered unreliable, and participant character attributes (e.g. age, appearance, weight or physical ability) led to clinician dismissal.

CONCLUSIONS

People with endometriosis of all age groups reported pervasive negative healthcare experiences during their adolescence. Patients experience delays in seeking care and in receiving a diagnosis once presenting for care.

The effect of endometriosis on anxiety and the Quality of Life in women

This descriptive and cross-sectional study was conducted with 420 women. The data were collected by using the "Descriptive Information Form", "SF-36 Quality of Life Scale (QoLS)" and "State Anxiety Inventory (SAI)". The data were evaluated with Mann-Whitney U-test, Student's t-test and Pearson correlation analysis. Endometriosis had been diagnosed in 12.1% of the women. The score medians obtained by the women with endometriosis from the pain and physical role difficulty sub-dimensions of the QoLS were found to be significantly lower than those obtained by women without endometriosis. The presence of endometriosis was found not to affect the state anxiety in the women. A weak or moderately significant negative relationship was found between the number and onset time of the symptoms and certain sub-dimensions of the QoLS in the women with endometriosis.

Endometriosis: A multimodal imaging review

Endometriosis is a chronic inflammatory disorder characterized endometrial-like tissue present outside of the uterus, affecting approximately 10% of reproductive age women. It is associated with abdomino-pelvic pain, infertility and other non - gynecologic symptoms, making it a challenging diagnosis. Several guidelines have been developed by different international societies to diagnose and classify endometriosis, yet areas of controversy and uncertainty remains. Transvaginal ultrasound (TV-US) is the first-line imaging modality used to identify endometriosis due to its accessibility and cost-efficacy. Enhanced sonographic techniques are emerging as a dedicated technique to evaluate deep infiltrating endometriosis (DIE), depending on the expertise of the sonographer as well as the location of the lesions. MRI is an ideal complementary modality to ultrasonography for pre-operative planning as it allows for a larger field-of-view when required and it has high levels of reproducibility and tolerability. Typically, endometriotic lesions appear hypoechoic on ultrasonography. On MRI, classical features include DIE T2 hypointensity, endometrioma T2 hypointensity and T1 hyperintensity, while superficial peritoneal endometriosis (SPE) is described as a small focus of T1 hyperintensity. Imaging has become a critical tool in the diagnosis, surveillance and surgical planning of endometriosis. This literature review is based mostly on studies from the last two decades and aims to provide a detailed overview of the imaging features of endometriosis as well as the advances and usefulness of different imaging modalities for this condition.

Clinical Diagnosis and Early Medical Management for Endometriosis: Consensus from Asian Expert Group

This work provides consensus guidance regarding clinical diagnosis and early medical management of endometriosis within Asia. Clinicians with expertise in endometriosis critically evaluated available evidence on clinical diagnosis and early medical management and their applicability to current clinical practices. Clinical diagnosis should focus on symptom recognition, which can be presumed to be endometriosis without laparoscopic confirmation. Transvaginal sonography can be appropriate for diagnosing pelvic endometriosis in select patients. For early empiric treatment, management of women with clinical presentation suggestive of endometriosis should be individualized and consider presentation and therapeutic need. Medical treatment is recommended to reduce endometriosis-associated pelvic pain for patients with no immediate pregnancy desires. Hormonal treatment can be considered for pelvic pain with a clinical endometriosis diagnosis; progestins are a first-line management option for early medical treatment, with oral progestin-based therapies generally a better option compared with combined oral contraceptives because of their safety profile. Dienogest can be used long-term if needed and a larger evidence base supports dienogest use compared with gonadotropin-releasing hormone agonists (GnRHa) as first-line medical therapy. GnRHa may be considered for first-line therapy in some specific situations or as short-term therapy before dienogest and non-steroidal anti-inflammatory drugs as add-on therapy for endometriosis-associated pelvic pain.

Ibero-American Endometriosis Patient Phenome: Demographics, Obstetric-Gynecologic Traits, and Symptomatology

Background: An international collaborative study was conducted to determine the demographic and clinical profiles of Hispanic/Latinx endometriosis patients from Latin America and Spain using the Minimal Clinical Questionnaire developed by the World Endometriosis Research Foundation (WERF) Endometriosis Phenome and Biobanking Harmonization Project (EPHect). Methods: This is a cross-sectional study to collect self-reported data on demographics, lifestyle, and endometriosis symptoms of Hispanic/Latinx endometriosis patients from April 2019 to February 2020. The EPHect Minimal Clinical Questionnaire (EPQ-M) was translated into Spanish. Comprehension and length of the translated survey were assessed by Spanish-speaking women. An electronic link was distributed via social media of endometriosis patient associations from 11 Latin American countries and Spain. Descriptive statistics (frequency, means and SD, percentages, and proportions) and correlations were conducted using SPSSv26. Results: The questionnaire was completed by 1,378 participants from 23 countries; 94.6% had self-reported diagnosis of endometriosis. Diagnostic delay was 6.6 years. Most participants had higher education, private health insurance, and were employed. The most common symptoms were back/leg pain (85.4%) and fatigue (80.7%). The mean number of children was 1.5; 34.4% had miscarriages; the mean length of infertility was 3.7 years; 47.2% reported pregnancy complications. The most common hormone treatment was oral contraceptives (47.0%). The most common comorbidities were migraines (24.1%), polycystic ovary syndrome (PCOS) (22.2%), and irritable bowel syndrome (21.1%). Most participants (97.0%) experienced pelvic pain during menses; for 78.7%, pain was severe; 86.4% reported dyspareunia. The mean age of dysmenorrhea onset was 16.2 years (SD ± 6.1). Hormone treatments were underutilized, while impact was substantial. Pain catastrophizing scores were significantly correlated with pain intensity (p < 0.001). Conclusion: This is the first comprehensive effort to generate a clinical-demographic profile of Hispanic/Latinx endometriosis patients. Differences in clinical presentation compared to other cohorts included higher prevalence and severity of dysmenorrhea and dyspareunia and high levels of pain catastrophizing. Though future studies are needed to dissect the impact of race and ethnicity on pain and impact, this profile is the first step to facilitate the recognition of risk factors and diagnostic features and promote improved clinical management of this patient population. The EPHect questionnaire is an efficient tool to capture data to allow comparisons across ethnicities and geographic regions and tackle disparities in endometriosis research.

Impact of the early COVID-19 era on endometriosis patients: Symptoms, stress, and access to care

Introduction:

Monitoring the impact of natural disasters such as pandemics on health and wellbeing is a public health priority. Stress is proven to affect pain intensity and quality of life of endometriosis patients. A cross-sectional study was conducted to determine whether the measures implemented to mitigate COVID-19 infections had a substantial impact on risk behaviors, endometriosis symptoms, stress, and access to healthcare.

Methods:

Electronic questionnaires that measured COVID-19 impact and peri-traumatic stress were disseminated through social media over June–September 2020 and completed by 82 adult patients with endometriosis living in Puerto Rico. Descriptive data analysis and correlations were done in quantitative data and systematic analysis of free text was done on qualitative responses.

Results:

Participants self-reported worsening of endometriosis symptoms and high levels of peri-traumatic stress, as well as changes in risk behaviors (exercise, nutrition, sedentarism, sleep) during the pandemic in comparison to the previous months. They also reported substantial barriers in access to medical appointments, scheduled procedures, and prescriptions. Electronic health modalities (telemedicine, mobile apps) were considered acceptable alternatives for gynecologic care during natural disasters.

Conclusion:

The COVID-19 pandemic negatively impacts the health and wellbeing of endometriosis patients while imposing substantial restrictions on access to health care. These timely insights will guide the development and implementation of plans to address barriers to health care and minimize long-term detrimental effects of natural disasters on the health of those living with stress-related disorders such as endometriosis.

Baseline endometriosis-associated pain burden: Data from 1600+ women enrolled in elagolix clinical trials

Background:

The daily pain burden experienced by women with endometriosis has not been well studied.

Objective:

To characterize baseline pain among women with moderate-to-severe endometriosis-associated pain enrolled in phase 3 studies of elagolix, an oral, nonpeptide gonadotropin-releasing hormone antagonist.

Study design:

Data were pooled from the screening phase of two randomized, double-blind, placebo-controlled clinical trials. After cessation of endometriosis medications, patients entered the screening phase during which symptoms (dysmenorrhea, nonmenstrual pelvic pain, and dyspareunia) and rescue medication use were recorded daily in electronic diaries. Endometriosis-associated pain was also scored using the Numeric Rating Scale (range 0–10). Baseline was defined as the last 35 days during the screening period.

Results:

Endometriosis-associated pain was reported by the 1686 study participants on most days during the baseline interval. Pain was often moderate or severe, with a mean Numeric Rating Scale score of 5.6 ± 1.7. Women reported dysmenorrhea an average of 8.1 ± 3.0 days (97.9% ± 7.0% of menstruating days), nonmenstrual pelvic pain on 20.5 ± 5.4 days (90.3% ± 15.8% of nonmenstruating days), and dyspareunia on 8.7 ± 8.0 days (81.7% ± 29.7% of sexually active days). When they occurred, dysmenorrhea, nonmenstrual pelvic pain, and dyspareunia were frequently moderate or severe in intensity. Women were free of pelvic pain for an average of 2.4 ± 3.9 days during the 35-day evaluation interval.

Conclusion:

Among women with untreated moderate-to-severe endometriosis pain, the daily burden of pain was extensive, both during menstruation and on nonmenstruating days.

Is Scientific Medical Literature Related to Endometriosis Treatment Evidence-Based? A Systematic Review on Methodological Quality of Randomized Clinical Trials

Background and objectives: Informed decision-making requires the ability to identify and integrate high-quality scientific evidence in daily practice. We aimed to assess whether randomized controlled trials (RCTs) on endometriosis therapy follow methodological criteria corresponding to the RCTs' specific level in the hierarchy of evidence in such details to allow the reproduction and replication of the study. Materials and Methods: Using the keywords "therapy" and "endometriosis" and "efficacy" three bibliographic databases were searched for English written scientific articles published from 1 January 2008 to 3 March 2018. Only the randomized clinical trials (RCTs) were evaluated in terms of whether they provided the appropriate level of scientific evidence, equivalent to level 1, degree 1b in the hierarchy of evidence. A list of criteria to ensure study replication and reproduction, considering CONSORT guideline and MECIR standards, was developed and used to evaluate RCTs' methodological soundness, and scores were granted. Three types of bias, namely selection bias (random sequence generation and allocation concealment), detection bias (blinding of outcome assessment), and attrition bias (incomplete outcome data) were also evaluated. Results: We found 387 articles on endometriosis therapy, of which 38 were RCTs: 30 double-blinded RCTs and 8 open-label RCTs. No article achieved the maximum score according to the evaluated methodological criteria. Even though 73.3% of the double-blinded RCTs had clear title, abstract, introduction, and objectives, only 13.3% provided precise information regarding experimental design and randomization, and also showed a low risk of bias. The blinding method was poorly reported in 43.3% of the double-blinded RCTs, while allocation concealment and random sequence generation were inadequate in 33.3% of them. Conclusions: None of the evaluated RCTs met all the methodological criteria, none had only a low risk of bias and provided sufficient details on methods and randomization to allow for the reproduction and replication of the study. Consequently, the appropriate level of scientific evidence (level 1, degree 1b) could not be granted. On endometriosis therapy, this study evaluated the quality of reporting in RCTs and not the quality of how the studies were performed.

Medical conditions, pregnancy perspectives and contraceptive decision-making among young people: an exploratory, qualitative analysis

OBJECTIVE

To explore perspectives on family planning among young people who perceive they are infertile or will have difficulty carrying a pregnancy to term owing to medical conditions or procedures.

METHODS

This exploratory analysis examined pregnancy plans and contraceptive behavior among 12 young adults with a diagnosed medical condition or who had undergone a medical procedure associated with impaired fertility, and who had discussed fertility with a healthcare provider. We utilized data from a larger study investigating prospective pregnancy intentions and plans among 50 young (ages 18-24) women and their male partners (n=100).

RESULTS

Medical conditions included endometriosis, polycystic ovary syndrome, and lupus. For some, medical conditions/procedures led to use of no or less effective contraception; perceived risk for pregnancy was low, though seven participants had previously experienced pregnancies. Participants also described how medical conditions altered their timelines for pregnancy and overall desire for children; for example, one participant described continuing an unplanned pregnancy because she feared it would be her only chance to parent.

CONCLUSION

This exploratory analysis suggests that among young people, medical issues perceived to affect fertility and pregnancy may influence pregnancy planning and contraceptive behavior. Young people may lack knowledge about fertility and the impact of a medical condition; thus it is critical that providers clarify the difference between anticipated difficulty conceiving and complete infertility. Tailored contraceptive care is needed for young adults with medical conditions that may affect fertility to ensure they have the necessary information to make informed family planning decisions.

IMPLICATIONS

Medical conditions known to affect fertility may influence young people's family planning desires and behaviors. Understanding how young adults process information about medical conditions' impact on their fertility and change or make plans in response is important in order to best meet their family planning needs.

Comparing the effects of Triptorelin and Calendula officinalis on size and pathology of induced endometriosis in rats

Background:

Endometriosis is defined as the growth of endometrial glands and stoma extra-uterine sites. It is an estrogen-dependent inflammatory disease estimated to affect 10% of women of reproductive age. This study aimed at comparing the effects of Triptorelin and Calendula officinalis on the induced endometriosis in female rats.

Materials and Methods:

In this experimental study in an animal model, 52 rats with induced endometriosis were divided into four groups. The control group was treated with 0.5 mL/kg normal saline orally, the second group with single intramuscular injection of Triptorelin S.R.11.25 (3 mg/kg), the third group with Calendula 1000 mg/kg, and the fourth group with Calendula 2000 mg/kg for 6 weeks. The mean area and volume of endometriosis and pathological scores of endometriotic implants were compared between groups.

Results:

After 6 weeks of treatment, Triptorelin was able to reduce the mean area and volume of endometriotic implants (p < 0.05), but Calendula did not have a significant effect compared to the control group. Mean rank of pathologic score in Triptorelin group had a significant difference with the control group and Calendula 1000 mg/kg (adjusted α < 0.001, adjusted α = 0.004). There was no significant difference in score between the control group and Calendula 1000 mg/kg and 2000 mg/kg.

Conclusion:

Based on our findings in the used doses, Calendula was not effective for the treatment of experimental endometriosis in rats.
