Prevalence of fibromyalgia and quality of life in women with and without endometriosis

Sexual Function of Patients with Deep Endometriosis after Surgical Treatment: A Systematic Review

OBJECTIVE

 To review the current state of knowledge on the impact of the surgical treatment on the sexual function and dyspareunia of deep endometriosis patients.

DATA SOURCE

 A systematic review was conducted in accordance with the Meta-Analysis of Observational Studies in Epidemiology (MOOSE) guidelines. We conducted systematic searches in the PubMed, EMBASE, LILACS, and Web of Science databases from inception until December 2022. The eligibility criteria were studies including: preoperative and postoperative comparative analyses; patients with a diagnosis of deep endometriosis; and questionnaires to measure sexual quality of life.

STUDY SELECTION

 Two reviewers screened and reviewed 1,100 full-text articles to analyze sexual function after the surgical treatment for deep endometriosis. The risk of bias was assessed using the Newcastle-Ottawa scale for observational studies and the Cochrane Collaboration's tool for randomized controlled trials. The present study was registered at the International Prospective Register of Systematic Reviews (PROSPERO; registration CRD42021289742).

DATA COLLECTION

 General variables about the studies, the surgical technique, complementary treatments, and questionnaires were inserted in an Microsoft Excel 2010 (Microsoft Corp., Redmond, WA, United States) spreadsheet.

SYNTHESIS OF DATA

 We included 20 studies in which the videolaparoscopy technique was used for the excision of deep infiltrating endometriosis. A meta-analysis could not be performed due to the substantial heterogeneity among the studies. Classes III and IV of the revised American Fertility Society classification were predominant and multiple surgical techniques for the treatment of endometriosis were performed. Standardized and validated questionnaires were applied to evaluate sexual function.

CONCLUSION

 Laparoscopic surgery is a complex procedure that involves multiple organs, and it has been proved to be effective in improving sexual function and dyspareunia in women with deep infiltrating endometriosis.

Comparing the quality of life of endometriotic patients' before and after treatment with normal and infertile patients based on the EHP30 questionnaire

OBJECTIVE

This study aimed to determine the quality of life (QOL), in patients with endometriosis ± infertility (B and C groups) and compare those to healthy women, and also infertile groups without endometriosis as a control groups (A and D), considering the fact that endometriosis and infertility reduces the quality of life in patients.

METHODS

The present prospective comparative study was carried out between January 2018 and September 2020. A total of 400 women were included (100 women in each group). The participants filled in a validated questionnaire of quality of life, Endometriosis Health Profile-30 (EHP-30), and a visual analog scale of pain used, at the first visit, and 3 months after the medical or surgical treatment in the endometriosis group without infertility, additionally.

RESULTS

The majority of the patients were married, categorized in the middle-class of socio-economic state and housewives. They were of Persian descent. BMI was high in the infertile groups; however, the time of infertility was not different between the two groups of B and C (P = 0.054). The mean score of QOL was significantly lower in B, C, and D groups in comparison to the healthy women as the control group (A) (P < 0.001). Moreover, the infertile group (B), in comparison to endometriosis ± infertility groups (C and D), had the lowest mean score of QOL (P < 0.001). In each group, those who were older and had better educational level reported a better quality of life than other participants in that group. Social support plays a very important role in reducing the endometriosis related pain symptoms both before and after treatment. Three months after the treatment of endometriosis (D), a significant improvement was observed in all the aspects of QOL-related endometriosis. Nonetheless, the improvement of the quality of life in the surgical group was significantly higher than that in the medical treatment. The mean visual analog score of pain decreased from 62.22 ± 22.78, to 5.15 ± 2.73 following the surgical treatment (P < 0.001).

CONCLUSION

The lowest quality of life belonged to the infertile group, followed by the endometriosis group. The quality of life of the endometriosis group improved after the treatment. Thus, endometriotic patients' treatment in terms of improvement of quality of life should be considered by all professional health care teams.

Evaluation of the SF-36 questionnaire for assessment of the quality of life of endometriosis patients undergoing treatment: A systematic review and meta-analysis

Endometriosis has a negative influence on the physical, psychological, and social aspects of a patient's life; therefore, it affects the health-related quality of life (HRQoL). The current review aimed to investigate the efficiency of a 36-item generic questionnaire survey (SF-36) for patients with endometriosis who were undergoing medical or surgical treatment. A search strategy including the key words ‘endometriosis’, ‘quality of life’ (QOL), and ‘questionnaire SF-36’ was applied using the PubMed/MEDLINE, EMBASE, and Cochrane databases in order to include articles that evaluated the QOL among women with endometriosis using the SF-36. Only articles that included interviews of patients both before and after surgical or medical endometriosis treatment or those articles that compared study groups were considered. The qualitative analysis was based on 37 articles, whereas the quantitative analysis utilized 14 articles. The research participants included 11,101 women, among whom 6,888 patients were diagnosed with endometriosis. The analysis recorded 17 studies dealing with all types of endometriosis, 9 studies dealing with deep infiltrative endometriosis (DIE), and 9 studies dealing with bowel endometriosis or DIE with bowel involvement. QOL was evaluated using only SF-36 in 12 studies that collectively included 1,912 women and using SF-36 in association with other questionnaires in 25 studies that collectively included 8,022 women. For patients with endometriosis, physical functioning [odds ratio (OR), 78.87; 95% confidence interval (CI), 68.97-88.77; I²=98.77%; P≤0.001] was the most affected life parameter. This parameter showed the highest improvement after surgical intervention (OR, 63.39; 95% CI, 48.71-78.07; I²=97.65%; P≤0.001) or hormonal treatment (OR, 38.65; 95% CI, 14.39-62.91; I²=38.65%; P≤0.001). The 36-item survey generic questionnaire seems to be an efficient tool for assessment of the QOL of life of women with endometriosis who are undergoing surgical or medical treatment. It can be applied before and after the procedure, and it can also be used for comparing study groups.

Sleep disturbances, fatigue and psychological health in women with endometriosis: a matched pair case-control study

RESEARCH QUESTION

What are the associations between endometriosis, pelvic pain symptoms, fatigue and sleep? Psychological health and quality of life in endometriosis patients with good versus bad quality of sleep were also examined.

DESIGN

This matched pair case-control study included 123 consecutive endometriosis patients and 123 women without a history of endometriosis (matched to patients for age and body mass index). Endometriosis-related pelvic pain severity was rated on a 0-10 numerical rating scale. Fatigue was measured on a 1-5 Likert scale. Women also completed a set of self-report questionnaires for assessing sleep disturbances (Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, Insomnia Severity Index), psychological health (Hospital Anxiety and Depression Scale) and quality of life (Short Form-12).

RESULTS

Painful endometriosis had an impact on fatigue (P = 0.006; η²_p = 0.041) and sleep (P < 0.001; η²_p = 0.051). Women with painful endometriosis reported significantly greater fatigue, poorer quality of sleep, higher daytime sleepiness and more severe insomnia than women without significant pain symptoms and controls. Poorer quality of sleep among endometriosis patients was associated with greater fatigue (P < 0.001; η²_p = 0.130), poorer psychological health (P < 0.001; η²_p = 0.135), and lower quality of life (P < 0.001; η²_p = 0.240).

CONCLUSIONS

Pelvic pain (rather than endometriosis in itself) is associated with fatigue and sleep disturbances, with poor sleep having a detrimental impact on women's psychological health and quality of life.

Does Endometriosis Disturb Mental Health and Quality of Life? A Systematic Review and Meta-Analysis

INTRODUCTION

This study aimed to evaluate whether endometriosis could disturb the mental health and health-related quality of life (HRQoL) of patients and to provide a new prospective for further treatment of endometriosis.

METHODS

A comprehensive literature review was conducted among 4 international databases (PubMed, Embase, Web of Science, and Cochrane Library) and 2 of the largest Chinese databases (the China National Knowledge Infrastructure and Wangfang). The Newcastle-Ottawa Scale was used to assess the quality of the included articles. Six effect sizes were synthesized through a meta-analysis, and a subgroup analysis was performed to identify potential moderating factors, including types of control groups, methods of assessment, number of study groups, and origin of the study. Potential publication bias was examined using a funnel plot.

RESULTS

This meta-analysis pooled 44 articles from 4 continents and 13 countries and compared 6 types of main effect sizes (the odds ratio [OR] for depression, the OR for anxiety, the standardized mean difference [SMD] for depression, the SMD for anxiety, the SMD for the physical component summary [PCS] and the SMD for the mental component summary [MCS]) between endometriosis patients and controls. Except for the SMD for depression, all other effect sizes revealed statistically significant differences between the study group and the controls. The main effect size outcomes of the subgroup analysis were also similar. The type of control group (I2 = 35% in non-endometriosis control groups for the SMD of anxiety; I2 = 47% in non-endometriosis control groups for the MCS of the 36-Item Short Form Health Survey) and the continent of origin (I2 = 0% in studies from South America for the OR of depression; I2 = 47% in studies from Europe for the SMD of anxiety) may influence heterogeneity in this analysis. Additionally, depression and anxiety symptoms in patients seemed to be more apparent compared with healthy controls when the sample was smaller and when a questionnaire was used. The publication bias of the articles was acceptable.

CONCLUSION

Endometriosis can disturb mental health (specifically depression and anxiety) and decrease both the mental and physical HRQoL of patients. There may be some moderating factors that we were unable to identify in the subgroup analysis, but more research is necessary to develop proper management and improve the prognosis of endometriosis patients.

Loss of HDAC3 results in nonreceptive endometrium and female infertility

Endometriosis is a disease in which tissue that normally grows inside the uterus grows outside the uterus and causes chronic pelvic pain and infertility. However, the exact mechanisms of the pathogenesis of endometriosis-associated infertility are unknown. Epigenetic dysregulation has recently been implicated in infertility. Here, we report a reduction of histone deacetylase 3 (HDAC3) protein amounts in eutopic endometrium of infertile women with endometriosis compared to a control group. To investigate the effect of HDAC3 loss in the uterus, we generated mice with conditional ablation of Hdac3 in progesterone receptor (PGR)-positive cells (Pgr^cre/+Hdac3^f/f ; Hdac3^d/d ). Loss of Hdac3 in the uterus of mice results in infertility due to implantation failure and decidualization defect. Expression microarray and ChIP-seq analyses identified COL1A1 and COL1A2 as direct targets of HDAC3 in both mice and humans. Reduction of HDAC3 abrogated decidualization in a primary culture of human endometrial stromal cells (hESCs) similar to that observed in infertile patients with endometriosis. Whereas attenuation of HDAC3 resulted in p300 recruitment to Col1a1 and Col1a2 genes in the uterus of mice as well as hESCs, inhibition of p300 permitted hESCs to undergo decidualization. Collectively, we found attenuation of HDAC3 and overexpression of collagen type I in the eutopic endometrium of infertile patients with endometriosis. HDAC3 loss caused a defect of decidualization through the aberrant transcriptional activation of Col1a1 and Col1a2 genes in mice and COL1A1 and COL1A2 genes in humans. Our results suggest that HDAC3 is critical for endometrial receptivity and decidualization.

Systematic review of quality of life measures in patients with endometriosis

OBJECTIVES

Endometriosis and quality of life has been the subject of much research, however, there is little consensus on how best to evaluate quality of life in endometriosis, resulting in many and diverse scales being used. In our study, we aim to identify quality of life scales used in endometriosis, to review their strengths and weaknesses and to establish what would define an ideal scale in the evaluation of endometriosis-related quality of life.

MATERIALS AND METHODS

A search of the MEDLINE and EMBASE databases was carried out for publications in English and French for the period from 1980 to February 2017, using the words 'endometriosis' and 'quality of life'. Publications were selected if they reported on quality of life in patients with endometriosis and specified use of a quality of life scale. A quantitative and a qualitative analysis of each scale was performed in order to establish the strengths and weaknesses for each scale (systematic registration number: PROSPERO 2014: CRD42014014210).

RESULTS

A total of 1538 articles publications were initially identified. After exclusion of duplicates and application of inclusion criteria, 201 studies were selected for analysis. The SF-36, a generic HRQoL measure, was found to be the most frequently used scale, followed by the EHP-30, a measure specific to endometriosis. Both perform well, when compared with other scales, with scale weaknesses offset by strengths. EHP-5 and EQ-5D also showed to be of good quality. All four were the only scales to report on MCID studied in endometriosis patients.

CONCLUSION

For clinical practice, routine evaluation of HRQOL in women with endometriosis is essential both for health-care providers and patients. Both SF-36 and EHP-30 perform better overall with regard to their strengths and weaknesses when compared to other scales.

Comorbid fibromyalgia: A qualitative review of prevalence and importance

Fibromyalgia (FM) may be an unrecognized cause of suffering for persons with an array of medical conditions. This is especially true for illness that is characterized by pain of any nature. Once believed to be a unique diagnosis, FM is recently reported to occur concomitantly with various rheumatic diseases, and importantly adversely impacts global health status. However, there is increasing report of FM associated with other diseases that are not defined by chronic pain. This qualitative review examines the evidence for comorbid FM in illness, and where available the effect of FM on the primary disease. Other than for musculoskeletal disorders, the published literature reporting an association of FM with illness is limited with scanty reports for some neurological, gastrointestinal, mental health and other overlapping pain conditions. Comorbid FM adversely affects both health status and outcome for rheumatic diseases, but with limited study in other diseases. When unrecognized, comorbid FM may be mistaken as poor control of the primary disease, leading to incorrect treatment decisions. FM may be a neglected condition that pervades many conditions and may contribute to the burden of illness. Physicians should be alert to the possibility of comorbid FM, and symptoms of FM should be specifically addressed.

SIGNIFICANCE

Comorbid fibromyalgia (FM) in other medical conditions is largely unrecognized. When reported as accompanying rheumatic diseases, FM adversely affects global health status. With limited reports of comorbid FM with other conditions, neglect to diagnose comorbid FM may misdirect treatments.

KLF10 Mediated Epigenetic Dysregulation of Epithelial CD40/CD154 Promotes Endometriosis

Endometriosis is a highly prevalent, chronic, heterogeneous, fibro-inflammatory disease that remains recalcitrant to conventional therapy. We previously showed that loss of KLF11, a transcription factor implicated in uterine disease, results in progression of endometriosis. Despite extensive homology, co-expression, and human disease association, loss of the paralog Klf10 causes a unique inflammatory, cystic endometriosis phenotype in contrast to fibrotic progression seen with loss of Klf11. We identify here for the first time a novel role for KLF10 in endometriosis. In an animal endometriosis model, unlike wild-type controls, Klf10^−/− animals developed cystic lesions with massive immune infiltrate and minimal peri-lesional fibrosis. The Klf10^−/− disease progression phenotype also contrasted with prolific fibrosis and minimal immune cell infiltration seen in Klf11^−/− animals. We further found that lesion genotype rather than that of the host determined each unique disease progression phenotype. Mechanistically, KLF10 regulated CD40/CD154-mediated immune pathways. Both inflammatory as well as fibrotic phenotypes are the commonest clinical manifestations in chronic fibro-inflammatory diseases such as endometriosis. The complementary, paralogous Klf10 and Klf11 models therefore offer novel insights into the mechanisms of inflammation and fibrosis in a disease-relevant context. Our data suggests that divergence in underlying gene dysregulation critically determines disease-phenotype predominance rather than the conventional paradigm of inflammation being precedent to fibrotic scarring. Heterogeneity in clinical progression and treatment response are thus likely from disparate gene regulation profiles. Characterization of disease phenotype-associated gene dysregulation offers novel approaches for developing targeted, individualized therapy for recurrent and recalcitrant chronic disease.
