Uncovering moderators of pain perception by women with endometriosis from Latin America and Spain: the roles of sociodemographics, racial self-identity, and pain catastrophizing

ABSTRACT

A cross-sectional multinational collaborative study on women with endometriosis from Latin America and Spain uncovered high levels of painful symptomatology and high pain catastrophizing scores. Associations between pain perception/catastrophizing and race/ethnicity have been documented. This study was conducted to uncover factors moderating pelvic pain severity, including socioeconomic variables, self-identified race, and pain catastrophizing in women with endometriosis from Latin America and Spain, a population encompassing diverse racial and sociocultural contexts. Self-reported data on demographics, clinical history, Ob-Gyn history, pelvic pain intensity, and pain catastrophizing were collected with the Spanish World Endometriosis Research Foundation (WERF) Endometriosis Phenome Project (EPhect) Clinical Questionnaire (ECQ). Multiple logistic regression was conducted to analyze effects of self-identified race, demographic clusters (defined as countries with similar racial population distribution), socioeconomic factors, and pain catastrophizing on reporting severe vs moderate-mild levels of dysmenorrhea, dyspareunia, and pelvic pain. Self-identified race did not affect the likelihood of reporting severe pelvic pain; however, there were significant differences in reporting severe dysmenorrhea at worst among demographic clusters. Older age was associated with severe dyspareunia at worst and recent pelvic pain. Pain catastrophizing score was highly predictive of reporting most types of severe pelvic pain, regardless of race and demographic cluster. These results negate a role of racial categories as moderator of pain in women from Latin America and Spain and support integration of pain catastrophizing assessments and psychological interventions into the pain management plan to enhance therapeutic outcomes and QoL for patients with endometriosis.

In the thicket of fears, doubts, and murky facts: some reflections on treatment modalities for endometriosis-associated pain

Endometriosis-associated pain can be managed by either surgery or hormonal therapy. The final decision as to which treatment modality to take is based on efficacy and possible complications of different treatment modalities, risk of recurrence, and the patient's wishes and preferences. But in the thicket of fears, doubts, and murky facts, the choice may ultimately be the trade-off between irrational fears and ignorance versus scientific evidence. We elaborate some pros and cons of the two treatment modalities and highlight some notable downsides of hormonal therapy, in particular the possible yet unquantified risk of long-term hormonal therapy for malignant transformation, perhaps with the only exception of combined oral contraceptives. Thus, when discussing with patients, we advocate the approach of discussing the advantages and disadvantages of all treatment options in detail, accounting for the known pros and cons with a full understanding of the predictive irrationality of human beings. For endometriosis-associated pain, surgery is definitely not a failure of medicine but, rather, a viable option, especially given the recently surfaced undercurrent of wariness and dissatisfaction with the current hormonal drugs among patients with endometriosis. Above all, there is a pressing need to fill the knowledge gap of perioperative interventions intended to reduce the risk of recurrence and to fulfill the demand for the development of safe and efficacious non-hormonal therapeutics.

Reoperation and pain-related outcomes after hysterectomy for endometriosis by oophorectomy status

BACKGROUND

More research is needed that compares the outcomes between those who underwent a hysterectomy for endometriosis with conservation of one or both ovaries and those who underwent a hysterectomy with bilateral salpingo-oophorectomy.

OBJECTIVE

This study aimed to compare the rate and types of reoperations (primary outcome) and use of other pain-related health services (secondary outcomes) among people who underwent a hysterectomy with conservation of both ovaries, those who underwent a hysterectomy with unilateral salpingo-oophorectomy, and those who underwent a hysterectomy with bilateral salpingo-oophorectomy.

STUDY DESIGN

This was a population-based, retrospective cohort study of 4489 patients aged 19 to 50 years in British Columbia, Canada, who underwent a hysterectomy for endometriosis between 2001 and 2016. Index surgeries were classified as hysterectomy alone (conservation of both ovaries), hysterectomy with unilateral salpingo-oophorectomy, or hysterectomy with bilateral salpingo-oophorectomy. Reoperation rate was the primary outcome. Secondary outcomes (measured at 3-12 months and 1-5 years after hysterectomy) included physician visits for endometriosis and pelvic pain, prescriptions filled for opioids, and use of hormonal suppression medications and hormone replacement therapy.

RESULTS

Reoperation rates were low across all groups, with 89.5% of all patients remaining reoperation free by the end of follow-up (median of 10 years; interquartile range, 6.1-14.3 years). Patients who underwent a hysterectomy alone were more likely to undergo at least 1 reoperation when compared with those who underwent a hysterectomy with bilateral salpingo-oophorectomy (13% vs 5%; P<.0001), most commonly an oophorectomy or adhesiolysis. When oophorectomy as reoperation was removed in a sensitivity analysis, this difference was partially attenuated (6% of hysterectomy alone group vs 3% of hysterectomy with bilateral salpingo-oophorectomy group undergoing at least 1 reoperation). All groups were very similar in terms of rates of physician visits for endometriosis or pelvic pain and the number of days of opioid prescriptions filled. Furthermore, the rate of hormonal suppression medication use was similar among the groups, whereas the rate of prescriptions filled for hormone replacement therapy after hysterectomy with bilateral salpingo-oophorectomy was 60.6% of patients who filled at least 1 prescription at 3 to 12 months after index surgery.

CONCLUSION

Patients who underwent a hysterectomy with bilateral salpingo-oophorectomy had a lower reoperation rate than those who underwent a hysterectomy with conservation of one or both ovaries. However, there was little difference between the groups for the secondary outcomes measured, including physician visits for endometriosis and pelvic pain, opioid use, and use of hormonal suppression medications, suggesting that persistent pelvic pain after hysterectomy for endometriosis may not differ substantively based on ovarian conservation status. One limitation was the inability to stratify patients by stage of endometriosis or to determine the impact of endometriosis stage or the presence of adnexal disease or deep endometriosis on the outcomes. Moreover, hormone replacement therapy prescriptions was not filled by about 40% of patients after hysterectomy with bilateral salpingo-oophorectomy, which may have significant health consequences for these individuals undergoing premature surgical menopause. Therefore, strong consideration should be given to ovarian conservation at the time of hysterectomy for endometriosis.

Endometriosis and Sexual Functioning: How Much Do Cognitive and Psycho-Emotional Factors Matter?

Women with endometriosis often suffer from genito-pelvic pain. The objective of the present study was to analyze the relationship between cognitive and psycho-emotional factors and sexual functioning of women with endometriosis, comparing women with and without endometriosis. A total of 87 women with endometriosis (EG) and 100 women without endometriosis (CG) completed a socio-demographic questionnaire; the short-form of McGill Pain Questionnaire (SF-MPQ); the Female Sexual Functioning Index (FSFI); the Sexual Distress Scale (SDS); the Symptoms Checklist (SCL-90-R); the Toronto Alexithymia Scale (TAS-20); the Positive and Negative Affects Scale (PANAS); the Sexual Dysfunctional Belief Questionnaire (SDBQ); the Sexual Modes Questionnaire (SMQ); and the Questionnaire of Cognitive Schema Activation in Sexual Context (QCSASC). EG obtained worse scores than CG in SF-MPQ, Pain subscale of FSFI, and SDS. EG reached higher scores than CG on almost all scales of SCL-90-R and lower scores in the “Identifying Feelings” scale of TAS-20. Furthermore, EG reported more negative emotions toward sexuality than CG (PANAS) higher scores on the “Affection Primacy” scale of SDBQ and the “Helpless” sexual cognitive schema of QCSASC than CG. No significant differences were found in SMQ. Sexual health professionals should address psychological, emotional, and cognitive factors since they seem involved in patients’ sexual experiences.
