Comparative analysis of endometrial, vaginal, and gut microbiota in patients with and without adenomyosis.

INTRODUCTION: Alterations in microbiota composition have been implicated in a variety of human diseases. Patients with adenomyosis present immune dysregulation leading to a persistent chronic inflammatory response. In this context, the hypothesis that alterations in the microbiota may be involved in the pathogenesis of adenomyosis, by affecting the epigenetic, immunologic, and biochemical functions of the host, has recently been postulated. The aim of the present study was to compare the microbiota composition in the vagina, endometrium, and gut of individuals with and without adenomyosis. MATERIAL AND METHODS: Cross-sectional study including 38 adenomyosis patients and 46 controls, performed between September 2021 and October 2022 in a university hospital-based research center. The diagnosis of adenomyosis was based on sonographic criteria. Fecal, vaginal, and endometrial samples were collected. Study of the microbiota using 16S rRNA gene sequencing. RESULTS: Patients with adenomyosis exhibited a significant reduction in the gut microbial alpha diversity compared with healthy controls (Chao1 p = 0.012, Fisher p = 0.005, Observed species p = 0.005). Beta-diversity analysis showed significant differences in the compositions of both gut and vaginal microbiota between adenomyosis patients and the control group (Adonis p-value = 0.001; R2 = 0.03 and Adonis p-value = 0.034; R2 = 0.04 respectively). Specific bacterial taxa were found to be either overrepresented (Rhodospirillales, Ruminococcus gauvreauii group, Ruminococcaceae, and Actinomyces) or underrepresented in the gut and endometrial microbiota of adenomyosis patients compared with controls. Distinct microbiota profiles were identified among patients with internal and external adenomyosis phenotypes. CONCLUSIONS: The study revealed reduced gut microbiota diversity in adenomyosis patients, accompanied by distinct compositions in gut and vaginal microbiota compared with controls. Overrepresented or underrepresented bacterial taxa were noted in the gut and endometrial microbiota of adenomyosis patients, with variations in microbiota profiles among those with internal and external adenomyosis phenotypes. These findings suggest a potential association between microbiota and adenomyosis, indicating the need for further research to comprehensively understand the implications of these differences.

Risk factors for irreversible unilateral loss of renal function in patients with deep endometriosis.

Deep endometriosis (DE) can be more aggressive than other types of endometriosis, and may even lead to irreversible severe complications such as complete unilateral loss of renal function. We aimed to describe the clinical and radiologic characteristics of DE patients diagnosed with irreversible unilateral loss of renal function due to unilateral ureteral stenosis and evaluate risk factors for developing this loss. This retrospective cohort study included 436 patients who underwent laparoscopic DE surgery. We evaluated two groups of patients according to preserved (Non-Renal Loss Group; n = 421) or irreversible unilateral damaged renal function (Renal Loss Group; n = 15). Preoperative epidemiologic variables, clinical characteristics, radiologic findings and surgical treatments of all the patients were collected. The Renal Loss Group had a higher infertility rate and a higher proportion of asymptomatic patients. The following radiological variables showed statistically significant differences between the two groups: mean endometrioma diameter, the presence of intestinal DE and negative sliding sign. Multivariate analysis showed that infertility, being asymptomatic, having intestinal DE or torus uterinus/uterosacral ligament DE and a negative sliding sign significantly increased the risk of loss of renal function. Therefore, among patients with these clinical and/or radiological variables, severe urinary tract obstruction should be specifically ruled out.

Adenomyosis is an independent risk factor for complications in deep endometriosis laparoscopic surgery.

Deep endometriosis (DE) occurs in 15-30% of patients with endometriosis and is associated with concomitant adenomyosis in around 25-49% of cases. There are no data about the effect of the presence of adenomyosis in terms of surgical outcomes and complications. Thus, the aim of the present study was to evaluate the impact of adenomyosis on surgical complications in women with deep endometriosis undergoing laparoscopic surgery. A retrospective cohort study including women referred to the endometriosis unit of a referral teaching hospital. Two expert sonographers preoperatively diagnosed DE and adenomyosis. DE was defined according to the criteria of the International Deep Endometriosis Analysis group. Adenomyosis was considered when 3 or more ultrasound criteria of the Morphological Uterus Sonographic Assessment group were present. Demographical variables, current medical treatment, symptoms, DE location, surgical time, hospital stay and difference in pre and post hemoglobin levels were collected. The Clavien-Dindo classification was used to assess surgical complications, and multivariate analysis was performed to compare patients with and without adenomyosis. 157 DE patients were included into the study; 77 (49.05%) had adenomyosis according to transvaginal ultrasound (TVS) and were classified in the A group, and 80 (50.95%) had no adenomyosis and were classified in the noA group. Adenomyosis was associated with a higher rate of surgical complications: 33.76% (A group) vs. 12.50% (noA group) (p < 0.001). Multivariate analysis showed a 4.56-fold increased risk of presenting complications in women with adenomyosis (CI 1.90-11.30; p = 0.001) independently of undergoing hysterectomy. There was a statistically significant association between the number of criteria of adenomyosis present in each patient and the proportion of patients presenting surgical complications (p < 0.001). Adenomyosis is an independent preoperative risk factor for surgical complications in DE surgery after adjustment for known demographic, clinical and surgical risk factors.

Impact of SARS-COV2 Pandemic on Patients with Endometriosis and Their Health Care.

Background: Endometriosis is a debilitating chronic inflammatory disease. The current SARS-COV2 pandemic has had an impact on the management of these patients. Tele-health care has been a relevant tool. The aim of this study was to analyze the impact of the SARS-COV2 pandemic on the perceived clinical health status and the type of care received in patients with endometriosis. Materials and Methods: We evaluated 945 premenopausal women treated at the Hospital Clinic of Barcelona between October 1 and December 31, 2020. Five hundred forty-nine women had endometriosis, and 396 had other benign gynecological diseases. An online health survey was sent to these patients. Clinicopathological features data were recorded. Results: Compared to patients with other benign gynecological diseases, a higher proportion of patients with endometriosis reported worsening of their symptoms (148/549, 27% vs. 85/396, 21.5%) and concern about their disease (515/549, 93.8% vs. 342/396, 86.4%), and more frequently received tele-health care (73.8% vs. 54.0%) during the pandemic. Patients with endometriosis and "significant" pelvic pain reported more concern and worsening than patients without "significant" pelvic pain, and evaluated the assistance received poorly. Multivariate analysis showed pelvic pain, limitation in usual activity, and sadness as risk factors of perception of disease worsening. Awaiting surgery and the feeling of sadness were risk factors of concern. Conclusions: Patients with endometriosis, and especially patients with "significant" pelvic pain, reported greater concern and the perception of worsening during the SARS-COV2 pandemic. Tele-health is a useful tool in patients with endometriosis, and face-to-face visit should be considered in those reporting "significant" pelvic pain.

Assessment of Quality of Life, Sexual Quality of Life, and Pain Symptoms in Deep Infiltrating Endometriosis Patients With or Without Associated Adenomyosis and the Influence of a Flexible Extended Combined Oral Contraceptive Regimen: Results of a Prospective, Observational Study.

BACKGROUND: The quality of life of women with deep infiltrating endometriosis (DIE) is impaired and may improve with combined oral contraceptives (COCs). AIM: To compare the overall and sexual quality of life of patients diagnosed with DIE with or without associated adenomyosis (AD) with that of healthy controls and determine the influence of a COC containing 2 mg dienogest/30 µg ethinyl estradiol on these aspects. METHODS: We enrolled 42 women diagnosed with DIE; 31 diagnosed with DIE + AD by transvaginal ultrasound, and 39 non-AD/DIE controls. All patients were interviewed regarding pain symptoms (dysmenorrhea, dyspareunia, dyschezia, and dysuria), heavy menstrual bleeding using the Pictorial Blood Loss Assessment Chart, quality of life using the Short Form-36 questionnaire (SF-36), and sexual quality of life using the Sexual Quality of Life-Female questionnaire (SQOL-F) and the Brief Profile of Female Sexual Function (B-PFSF) before starting COCs and after 12 months of treatment. OUTCOMES: There was significant improvement in overall and sexual quality of life after treatment in DIE and DIE + AD patients. RESULTS: Non-AD/DIE controls showed significantly higher scores in the B-PFSF, the SQOL-F and the SF-36 questionnaires (P < .05) at baseline versus the other groups. DIE + AD patients showed poorer quality of sexual life and greater intensity in pain symptoms compared with DIE patients. After 12 months of treatment, there was a significant improvement in overall and sexual quality of life in the DIE and DIE + AD groups, with improvement in sexual quality of life being slightly greater in DIE + AD patients compared with DIE patients. Pain symptoms also decreased in both groups. CLINICAL IMPLICATIONS: Patients with DIE + AD showed greater impairment in overall and sexual quality of life compared with patients with isolated DIE which seems to improve with a COC containing 2 mg dienogest/30 µg ethinyl estradiol. STRENGTHS & LIMITATIONS: Strengths include the long-term follow up, assessment of the impact of two associated conditions, and administration of the same COC in all patients. Limitations include the relatively small sample size, and the fact that we did not assess the effectiveness of a flexible extended COC regimen containing 2 mg dienogest/30 µg ethinyl estradiol since the groups were different at baseline. CONCLUSION: Patients diagnosed with DIE with or without AD have a decreased quality of life which may improve with a COC containing 2 mg dienogest/30 µg ethinyl estradiol. Further research is needed to confirm our results. Alcalde AM, Martínez-Zamora MÁ, Gracia M, et al.

Assessment of Sexual Quality of Life and Satisfaction in Couple Relationships Among Women With Deep Infiltrating Endometriosis and Adenomyosis.

Adenomyosis and endometriosis are similar gynecological diseases that decrease sexual quality of life and, in the case of endometriosis, satisfaction in couple relationships. This study aimed to assess sexual quality of life and couple satisfaction in women diagnosed with adenomyosis (AD) or deep infiltrating endometriosis (DIE). The study population included three groups of couples: one composed of 58 couples in which the woman was diagnosed with AD by transvaginal ultrasound (AD group), a second group comprising 55 couples in which the woman was diagnosed with isolated DIE by transvaginal ultrasound (DIE group), and a third group composed of 60 couples in which the women did not have AD or endometriosis (non-AD/DIE group). All women completed the Sexual Quality of Life-Female (SQOL-F) questionnaire, and all the couples completed the Dyadic Adjustment Scale (DAS). Sexual quality of life was significantly worse in women with AD or DIE compared with non-AD/DIE controls. Dyadic adjustment was significantly worse in the AD and DIE groups compared with the non-AD/DIE group. AD and DIE may impair quality of sexual life and couple relationships. Clinicians should be aware of this issue when treating women with AD or DIE.

Management of symptomatic uterine fibroids after ulipristal acetate suspension and identification of high risk patients for surgery at 6-months of follow-up.

OBJECTIVE: The use of ulipristal acetate (UPA) was indicated for the treatment of uterine fibroids. Following UPA suspension in March 2020, some patients presented worsening and required surgery. We aimed to identify patients at high-risk for undergoing surgery after UPA suspension. METHODS: We evaluated 85 women receiving intermittent UPA treatment until March 2020. Following UPA suspension, patients received other medical treatments or surgery. The clinico-pathological features were recoded and a quality of life health survey was completed by patients at the time of UPA suspension and at 6-months thereafter. RESULTS: After the suspension of UPA, 17 of the 85 patients receiving intermittent UPA (20%) required surgery, and 68 (80%) required other medical treatments. Patients who underwent surgery were younger and had greater fibroid volume. CONCLUSIONS: In our series, 20% of clinically stable patients receiving intermittent UPA required surgery following UPA suspension. These women should be considered for future medical strategies.

Long-term Follow-up of Sexual Quality of Life after Laparoscopic Surgery in Patients with Deep Infiltrating Endometriosis.

STUDY OBJECTIVE: We performed a long-term follow-up to quantify the impairment of sexual quality of life (SQL) and health-related QL (HRQL) in sexually active women after laparoscopic excision of deep infiltrating endometriosis (DIE). DESIGN: Prospective case-control study. SETTING: Hospital Clinic of Barcelona. PATIENTS: A total of 193 patients (after dropout and exclusions) were divided into 2 groups: one hundred twenty-nine premenopausal women with DIE (DIE group) and 64 healthy women who underwent tubal ligation (C group). INTERVENTIONS: All patients underwent laparoscopic surgery: laparoscopic endometriosis surgery in the DIE group and laparoscopic tubal ligation in the C group. All women were followed for at least 36 months, and they completed the Medical Outcomes Study 36-item short form questionnaire to assess their HRQL and 3 self-administered questionnaires that evaluate different aspects of SQL: the generic Sexual Quality of Life-Female questionnaire, the Female Sexual Distress Scale to evaluate "sexually related distress," and the Brief Profile of Female Sexual Function to screen hypoactive sexual desire disorder. The patients with DIE as well as the controls completed the 4 questionnaires before surgery, and the patients with DIE also completed the questionnaires at 6 and 36 months after surgery. MEASUREMENTS AND MAIN RESULTS: A comparison of the patients and controls before surgery showed a statistically significant impairment in SQL and HRQL among the patients with DIE. A statistically significant improvement in SQL and HRQL was observed in the DIE group 6 months after surgery, with scores being similar to those of the C group. An evaluation 36 months after surgery showed that SQL and HRQL were better than presurgical SQL and HRQL in the DIE group, with a slight reduction compared with the 6-month evaluation. CONCLUSION: SQL and HRQL improved in patients with DIE undergoing complete laparoscopic endometriosis resection and were comparable to those of healthy women at 6 months after surgery, showing a slight reduction at 36 months of follow-up.

Assessment of quality of sexual life in women with adenomyosis.

This study aimed to assess the impact of adenomyosis (AD) on different domains of sexual life. The study population included three groups: one composed of 68 women diagnosed with AD by transvaginal ultrasound, a second group comprised by 65 women diagnosed with isolated deep infiltrating endometriosis by transvaginal ultrasound and a third group including 70 women without AD or/and endometriosis. All participants completed the Brief Profile of Female Sexual Function (B-PFSF), the Female Sexual Distress Scale (FSDS), and the Sexual Quality of Life-Female (SQOL-F) questionnaire. Compared with non-AD/DIE controls, women with AD present significantly lower scores of the B-PFSF and the SQOL-F questionnaires and higher FSDS questionnaire scores (p < .0001). There were no differences between the groups of AD and deep infiltrating endometriosis. Clinicians should be aware that the quality of sexual life may be affected in patients with AD. Early diagnosis and multidisciplinary management would contribute to preventing impairment of sexual quality of life in these patients.

Impact of Adenomyosis on Women's Psychological Health and Work Productivity: A Comparative Cross-Sectional Study.

Background: Quality of life in adenomyosis (AD) patients has been poorly investigated. Previous data suggest that AD has negative impact on the quality of life in these women. Materials and Methods: From September 2018 to December 2019, all consecutive female premenopausal patients aged ≥18 years diagnosed with AD by transvaginal ultrasound (TVU) were invited to participate in a comparative cross-sectional study. The Short Form-36-item (SF-36) health questionnaire and the Hospital Anxiety and Depression Scale (HADS) were administered. Work productivity and activity impairment were assessed using the Work Productivity and Activity Impairment Questionnaire: General Health version (WPAI:GH). Data obtained from these patients were compared with women with normal-appearing myometrium in the TVU recruited during routine gynecological visits. The study was approved by the Clinical Research Ethics Committee of the Hospital Clinic (reference HCB/2018/0919). Results: One hundred three patients with AD and 214 without AD were analyzed. Patients with AD compared to those without AD showed significantly lower scores in all domains of the SF-36 questionnaire and mean (SD) higher scores in the HADS questionnaire for anxiety (10.06 [3.04] vs. 6.92 [2.98], p < 0.001) and depression (6.39 [3.89] vs. 2.74 [2.01], p < 0.002). Significant differences (p < 0.001) were also found for the percentages of absenteeism (12.2% vs. 1.1%), presenteeism (31.1% vs. 11.4%), overall work productivity loss (38.2% vs. 12.4%), and activity impairment (55.7% vs. 9.9%). The presence of AD was associated with higher yearly estimated indirect costs of €5161.32 (€7928.0 vs. €2460.8, p < 0.001). Conclusions: AD negatively affects women's health-related quality of life, psychological health, and work productivity, with impairment at work and daily activities, and higher risk for anxiety and depression.

Accuracy of Transvaginal Ultrasound Compared to Cystoscopy in the Diagnosis of Bladder Endometriosis Nodules.

OBJECTIVES: To evaluate the accuracy of transvaginal ultrasound (TVUS) in predicting detrusor infiltration and ureteral meatus involvement in patients with bladder endometriosis (BE) to select which cystoscopic procedures could be avoided and, secondarily, to assess the relationship between symptoms and the characteristics of nodules and the association of BE with other forms of endometriosis. METHODS: Patients with BE diagnosed by TVUS were classified according to detrusor infiltration: BE with partial involvement of the muscular layer (group 1) and total muscular layer involvement with bladder protrusion (group 2). We analyzed the accuracy of TVUS compared with subsequently performed cystoscopy, the correlation with symptoms, and the association with other forms of endometriosis. RESULTS: Among the 22 patients included, TVUS showed 9 patients with BE nodules partially affecting the detrusor (group 1) with normal cystoscopic findings (TVUS negative predictive value, 100%). Transvaginal ultrasound detected 13 nodules with total involvement, all visible by cystoscopy (TVUS positive predictive value, 100%). Transvaginal ultrasound also identified ureteral orifices that were free of involvement at greater than 10 mm from the BE nodule in 21 of 22 women (TVUS sensitivity, 95%). Ultrasound criteria for adenomyosis and endometriosis in other locations were present in 20 of 22 patients. CONCLUSIONS: Transvaginal ultrasound can identify the infiltration of BE nodules in the bladder wall and predict cystoscopic findings with great accuracy. Nodules that partially affect the muscular layer have normal cystoscopic findings, thereby obviating the need for this procedure. Bladder endometriosis nodules are commonly associated with other forms of endometriosis and do not usually affect the ureteral meatus.

Impact of endometrioma surgery on ovarian reserve: a prospective, randomized, pilot study comparing stripping with CO2 laser vaporization in patients with bilateral endometriomas.

OBJECTIVE: To assess ovarian reserve through antral follicle count (AFC) and ovarian volume (OV) determination after decapsulation (stripping technique) or CO2 laser vaporization in the surgical treatment of patients with bilateral ovarian endometriomas. METHODS: This prospective, randomized, blinded, self-controlled pilot study was set in a tertiary university hospital between January 2017 and December 2017, and included consecutive patients with bilateral ovarian endometriomas ≥3 cm. The study was registered with ClinicalTrials.gov under the title 'Impact on ovarian reserve according to the type of ovarian endometrioma excision: laser versus conventional cystectomy'; NCT03826355. For each patient, the endometrioma on one side was randomly selected to undergo CO2 laser vaporization and the contralateral endometrioma to undergo laparoscopic decapsulation. RESULTS: A total of 16 patients were included. There were no statistically significant between-group differences in OV and AFC levels at baseline. At the 6-month follow-up, OV and AFC levels were significantly higher in the laser-treated group versus the stripping technique. CONCLUSION: Lower OV and AFC levels following excisional surgery for endometrioma versus CO2 laser vaporization suggest a higher impact on ovarian reserve after the stripping procedure.

Prevalence of fibromyalgia among women with deep infiltrating endometriosis.

OBJECTIVE: To estimate the prevalence of fibromyalgia among women with endometriosis and analyze the effect of fibromyalgia on health-related quality of life (HRQoL). METHODS: An observational case-control study conducted at a tertiary hospital in Barcelona between April 2015 and March 2017 among women with deep infiltrating endometriosis (DIE; n=80), women with superficial endometriosis or ovarian endometrioma (non-DIE; n=76), and control women without endometriosis (n=73). Fibromyalgia was assessed via the London Fibromyalgia Epidemiological Study Screening Questionnaire (LFESSQ). HRQoL was evaluated with the 36-Item Short Form (SF-36) questionnaire. The impact of fibromyalgia and other clinical characteristics was assessed by multivariate regression analysis. RESULTS: More women fulfilled the criteria for fibromyalgia in the DIE group than in the non-DIE and control groups by LFESSQ-4 (31 [39%], 12 [16%], and 6 [8%], respectively; P=0.009) and LFESSQ-6 (22 [28%], 8 [11%], and 4 [5%], respectively; P=0.008). The DIE group reported significantly poorer HRQoL for all SF-36 dimensions. Women with DIE who fulfilled the criteria for fibromyalgia had lower physical component scores (-31.6; 95% confidence interval, -50.8 to -12.3; P=0.003). CONCLUSION: The estimated prevalence of fibromyalgia was higher among women with DIE. Women with DIE and positive fibromyalgia screening had lower HRQoL.

Circulating Neutrophil Extracellular Traps Are Elevated in Patients With Deep Infiltrating Endometriosis.

Neutrophil extracellular traps (NETs) have been described to be related to the pathogenesis of inflammatory and autoimmune conditions. Endometriosis is currently considered a chronic inflammatory condition. Therefore, we performed a preliminary case-control study to compare the circulating plasma NET levels in patients with surgically confirmed endometriosis (E group, n = 82) and those of patients without surgical findings of endometriosis (C group, n = 35). Venous blood samples were obtained at the time of surgery. Circulating plasma NET levels were assessed as histone-DNA complexes (ie, nucleosomes) by a quantitative sandwich enzyme-linked immunosorbent assay. The results were expressed in arbitrary units. Circulating plasma NET levels were significantly higher in the E group compared with the C group (median [25th; 75th percentiles]): E group: 0.734 [0.484; 1.363]; C group: 0.541 [0.411; 0.653]; P = .005). The subanalysis of E group patients with deep infiltrating endometriosis (DIE group) or without DIE (non-DIE group) showed that plasma NET levels were higher in the DIE group ( P = .02). No differences were observed in NET levels among patients with and without severe pelvic pain or in patients with and without infertility, regardless of the presence of endometriotic lesions. Therefore, our study shows significantly higher NET levels in patients with endometriosis, which seem to be attributed to increased levels in the subgroup of patients with DIE, suggesting that the presence of elevated circulating plasma NET levels may reflect an inflammatory status in this gynecological condition. Further research is warranted to confirm our findings and to assess the exact role of NETs in the pathophysiological mechanisms of endometriosis.

Total Circulating Microparticle Levels After Laparoscopic Surgical Treatment for Endometrioma: A Pilot, Prospective, Randomized Study Comparing Stripping with CO2 Laser Vaporization.

STUDY OBJECTIVE: To evaluate serial generation of microparticles (MPs) after laparoscopic stripping or CO2 laser vaporization in the surgical treatment of patients with ovarian endometrioma (OE). DESIGN: A prospective, randomized, blinded, pilot study (Canadian Task Force classification I). SETTING: Tertiary care university hospital from December 2014 to July 2016. PATIENTS: Thirty women with unilateral OE undergoing laparoscopic surgery. INTERVENTION: Patients were randomly selected to undergo either CO2 laser vaporization (L group) or laparoscopic stripping (S group) of OE. MEASUREMENTS AND MAIN RESULTS: Blood samples were collected before surgery and at 2 hours, 24 hours, 1 month, and 3 months after surgery. An MP generation curve after OE surgery was created. MP generation was greater in the S group than in the L group at all time points evaluated. The MP generation curve showed a significantly higher area under the curve after excisional surgery (p <.05). CONCLUSION: The higher MP levels in the S group suggest an increased inflammation and procoagulant response after this procedure.

Sonographic and hysteroscopic endometrial examination in women treated with ulipristal acetate: Exploratory findings at a tertiary referral center.

OBJECTIVE: Ulipristal acetate (UPA) is a progesterone receptor modulator (PRM) agent that has shown benefits in women with symptomatic uterine fibroids. However, its effects on the endometrium are complex and not fully understood. We describe exploratory findings on macroscopic observation of the endometrium at transvaginal sonography (TVS) and hysteroscopy. The aim of the study is to characterize endometrial patterns commonly observed after UPA treatment. STUDY DESIGN: We performed a prospective longitudinal study at a tertiary referral center with 100 women with symptomatic uterine fibroids who received a 12-week treatment with UPA (5 mg/day). Patients underwent TVS before and after the treatment, and also a hysteroscopy examination was performed. Main outcome was to compare sonographic and hysteroscopic findings to histology after UPA treatment. RESULTS: Twenty one out of 100 (21%) women showed PAEC confirmed by histology after UPA treatment. Ultrasound findings were normal in most women after UPA treatment, but 18/100 (18%) showed an endometrial pattern suggestive of PRM effects (non-uniform, homogeneous endometrium with regular cystic areas). Endometrial thickness ≥16 mm was detected in 6/100 patients (6%), and all of them also presented sonographic PRM pattern. No patient presented malignancy according to histology in this subgroup, and 100% of them had PAEC pattern at histology. Among total patient population showing PAEC at histology, only 33% of these were identified by hysteroscopy, while 57% were identified by TVS with the PRM suggestive pattern. Of note, visibility of endometrium was improved at TVS after UPA. CONCLUSION: Identification of increased endometrial thickness together with the categorized endometrial PRM pattern at TVS may be correlated to benign lesions and may not be a cause of concern. This study is exploratory and further research is necessary to support these conclusions. Nevertheless, TVS seems to be feasible to plan adequate follow-up protocols by avoiding unnecessary interventional procedures such as hysteroscopy.

Ulipristal Acetate Improves Clinical Symptoms in Women with Adenomyosis and Uterine Myomas.

STUDY OBJECTIVE: To study the effects of ulipristal acetate (UPA) on adenomyosis-associated clinical symptoms. DESIGN: A retrospective, single-center observational study (Canadian Task Force classification II-2). SETTING: A university tertiary referral center. PATIENTS: Premenopausal women (163) with adenomyosis and symptomatic uterine myomas (41 patients, A + F group) versus a control group with only myomas (122 patients, F group) treated with the first course of UPA. INTERVENTIONS: This was a retrospective study to assess the effects of a 12-week course of UPA (5 mg/d). MEASUREMENTS AND MAIN RESULTS: Clinical symptoms including bleeding control, amenorrhea, pain outcomes, and self-perceived severity of the disease and quality of life. Amenorrhea was present in 90.4% of the A + F group compared with 77.6% in the F group (p = .0017). Optimal bleeding control was significantly higher in the adenomyosis group (pictorial blood loss assessment chart < 75) than in the F group (90.2% vs 73.8%, p = .028). At the end of the first UPA course, the self-reported visual analog scale scores in the A + F group were significantly higher than in the F group (p = .017), reflecting greater improvement in pain outcomes for women with adenomyosis. UPA treatment improved the quality of life in both study groups. Most of the women rated their global health status as "better" after the first UPA course than before the treatment (A + F group: 67.00% and F group: 80.50%, p = .223). CONCLUSION: Treatment with UPA led to a significant reduction in the clinical symptoms of adenomyosis (bleeding and pain) and achieved a high rate of amenorrhea in a cohort of women with concomitant uterine myomas. Despite the limitations of the study, our results showed that UPA might be a good alternative treatment for adenomyosis.

Endometriotic Pain Is Associated with Adenomyosis but Not with the Compartments Affected by Deep Infiltrating Endometriosis.

BACKGROUND: The identification of presurgical clinical markers may be helpful to allow the staging of endometriosis severity. It has been suggested that pain characteristics orientate the gynecologist about the anatomical involvement of endometriosis. The study was performed to analyze the correlation between pain symptoms and the anatomical location of endometriosis. METHODS: One hundred fifty-five consecutive patients with a complete removal of deep infiltrating endometriosis (DIE) were included. Prior to surgery, data on patient and disease characteristics were obtained. The intensity of the pain symptoms was registered using a Visual Analogue Scale. The endometriotic lesions were categorized according to the Enzian morphological classification. Correlation and multivariate analysis were performed to assess the potential associations between pain characteristics (dysmenorrhea, pelvic pain, dyschezia, dyspareunia or dysuria) and the location of endometriosis or other disease-related characteristics (hematuria, rectal bleeding or adenomyosis). RESULTS: Pelvic pain was significantly associated with the presence of adenomyosis. Dyschezia was correlated with rectal bleeding and dysuria with the presence of hematuria. No relationship was found between other kinds of pain and the morphological location of endometriosis or other disease-related characteristics. CONCLUSION: Our data suggest that pelvic pain is correlated with the presence of adenomyosis in women with DIE. Further studies are required.

Ovarian endometrioma but not deep infiltrating endometriosis is associated with increased serum levels of interleukin-8 and interleukin-6.

Cytokines, and specifically interleukin 6 (IL-6) and interleukin 8 (IL-8), have been associated with the pathogenesis of endometriosis. We studied serum concentrations of IL-6 and IL-8 in patients with deep infiltrating endometriosis (DIE) or ovarian endometriomas (OE), but no other forms of associated endometriosis disease type. We carried out a case-control study including 19 patients with OE alone (OE group), 14 patients with DIE alone (DIE group) and 24 healthy patients without endometriosis (C group). Serum concentrations of IL-6 and IL-8 were measured in the three groups of patients. Serum levels of both IL-6 and IL-8 were significantly higher in the OE group. A high positive correlation was found between serum IL-6 and IL-8 levels in the OE group but not in the DIE and C groups. Serum IL-8 alone achieved the highest predictive value of the presence of OE (adjusted OR: 1.44; sensitivity: 78.2%; specificity: 76.2%). The combination of IL-6 and IL-8 levels did not significantly improve the discrimination between subjects with OE and those with DIE over that of IL-8. OE but not DIE are associated with increased serum levels of IL-6 and IL-8, and thus these may become useful tools for discriminating OE alone from DIE.
