Vitamin C and E antioxidant supplementation may significantly reduce pain symptoms in endometriosis: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: The primary challenge encountered by individuals diagnosed with endometriosis is the experience of pain. Emerging research indicates that oxidative stress is implicated in the initiation of pain associated with endometriosis. Vitamins C and E are known for their antioxidative properties. The primary objective of this study is to assess the efficacy of antioxidant supplementation, consisting of these vitamins, in the management of pain associated with endometriosis. METHODS: A comprehensive search was conducted on the ClinicalTrials.gov, Scopus, Europe PMC, and Medline databases up until August 23rd, 2023, utilizing a combination of relevant keywords. This review incorporates literature that examines the relationship between antioxidant supplementation and pain in endometriosis. We employed fixed-effect models to analyze the risk ratio (RR) and present the outcomes together with their corresponding 95% confidence intervals (CI). RESULTS: A total of five RCTs were incorporated. The results of our meta-analysis indicated that antioxidant supplementation with vitamin C and E combination was associated with higher proportion of endometriosis patients reporting reduced chronic pelvic pain (RR 7.30; 95%CI: 3.27-16.31, p<0.00001, I2 = 0%), alleviations of dysmenorrhea (RR 1.96; 95%CI: 1.25-3.07, p = 0.003, I2 = 39%), and dyspareunia (RR 5.08; 95%CI: 2.10-12.26, p = 0.0003, I2 = 0%) than patients only receiving placebo. CONCLUSIONS: This study suggests the potential ability of vitamin C and E in alleviating pain symptoms experienced by individuals with endometriosis.

An effective non-hormonal option with high tolerability for mild to moderate symptoms of vaginal dryness associated with menopause.

OBJECTIVES: The efficacy and tolerability of a non-hormonal pessary (that forms an oil-in-water emollient with the vaginal fluid) were assessed for the treatment of symptoms of vaginal dryness associated with menopause. STUDY DESIGN: Seventy-nine postmenopausal women (mean age 60.8 ± 6.5 years) with mild to moderate symptoms of vaginal dryness (including dyspareunia) were enrolled in this open-label, prospective, post-market clinical follow-up trial, conducted in 2022 by one research center in Germany. The investigational pessary was applied for the first 7 days once daily and the subsequent 31 days twice a week, at bedtime. A treatment-free period of 6 days completed the trial. MAIN OUTCOME MEASURES: During the trial, participants filled out questionnaires that enabled the calculation of a total severity score for subjective symptoms of atrophy-related vaginal dryness and impairment of daily as well as sexual life. Furthermore, vaginal health index and safety were studied. RESULTS: A rapid and significant reduction in the severity scores for symptoms was observed over the 38-day course of treatment and beyond. Quality of life assessed by DIVA (day-to-day impact of vaginal aging) questionnaire, dyspareunia and vaginal health index also clearly improved. The tolerability was mainly rated as "good to very good" by the investigator and 94.9 % of participants. The vast majority were very satisfied with the simple and pleasant handling. No serious adverse events occurred. CONCLUSION: Overall, the presented data suggest that the investigated non-hormonal pessary is an effective and well tolerated treatment option for vaginal symptoms associated with dryness, thus improving quality of life for women, even those who are sexually active.

Comparison of the effect of noninvasive radiofrequency with vaginal estrogen and vaginal moisturizer in the treatment of vulvovaginal atrophy in postmenopausal women: a randomized clinical trial.

OBJECTIVE: To compare the effect of noninvasive radiofrequency (RF) with vaginal estrogen (E), and vaginal moisturizer (M) on improving vulvovaginal atrophy (VVA) in women with genitourinary syndrome of menopause. METHODS: A total of 32 postmenopausal women who met the inclusion criteria were randomized into three intervention arms to receive one of the following treatments: three sessions of noninvasive RF therapy (RF arm); intravaginal estriol cream 1 mg applied daily for 2 weeks, followed by 1 mg applied two times weekly or 1 mg of estradiol vaginal fast-dissolving film applied daily for 2 weeks, followed by 1 mg applied two times weekly (E arm); and intravaginal moisturizer two times a week (M arm). Assessments at baseline and after 4 months were conducted using Vaginal Health Index score, Vaginal Maturation, visual analog scale for VVA symptoms (dyspareunia, dryness, and burning), and Menopause Rating Scale (MRS) for urogenital symptoms. Vaginal wall biopsies were administered to participants who consented, pretreatment and posttreatment (at baseline and after 4 months of follow-up). RESULTS: After 4 months, the Vaginal Health Index showed an increase of 6.6 points in mean total score in the RF arm, also in the E arm (+7.3 points), with no significant improvement in the M arm (+1.5 points) (interaction effect: RF, E ≠ M, P < 0.001). Regarding vaginal maturation, there was a significant increase in superficial cells in the E arm (+31.3), with no significant changes in the RF (+9.3) and M (-0.5) arms (interaction effect: E ≠ M, P < 0.001). Vaginal pH decreased significantly in the E arm (-1.25), with a similar response in the RF arm (-1.7), with no significant improvement in the M arm (-0.25) (interaction effect: RF, E ≠ M, P < 0.001).There was a significant improvement in the MRS score for VVA symptoms in the three intervention arms, with no predominance of any arm, whereas the improvement in the total MRS score for urogenital symptoms showed a predominance of the RF arm (ΔRF: -7.8; ΔE: -3.5; ΔM: -2.3; RF ≠ E, M). According to histopathologic analysis, there was no statistically significant increase in glycogenation ( P = 0.691) or epithelial cone height ( P = 0.935), despite an increase in the median delta (difference between pretreatment and posttreatment) in the three intervention arms (glycogenation: RF arm Δ = +118.4%; E arm Δ = +130.9%; M arm Δ = +24.9%; epithelial cone height: RF arm Δ = +33.5%; E arm Δ = +18.6%; M arm Δ = +22.3%). CONCLUSION: The effect of noninvasive RF on the treatment of vulvovaginal symptoms of genitourinary syndrome of menopause was similar to vaginal estrogen, except for hormonal cytology, and superior to vaginal moisturizer, with improvement in some histomorphometric parameters. These findings are promising, especially for the population that cannot or prefers not to use vaginal estrogen therapy.

Two-year efficacy and safety of relugolix combination therapy in women with endometriosis-associated pain: SPIRIT open-label extension study.

STUDY QUESTION: What is the efficacy and safety of long-term treatment (up to 2 years) with relugolix combination therapy (CT) in women with moderate to severe endometriosis-associated pain? SUMMARY ANSWER: For up to 2 years, treatment with relugolix CT improved menstrual and non-menstrual pain, dyspareunia, and function in women with endometriosis; after an initial decline of <1%, the mean bone mineral density (BMD) remained stable with continued treatment. WHAT IS KNOWN ALREADY: Endometriosis is a chronic condition characterized by symptoms of dysmenorrhea, non-menstrual pelvic pain (NMPP), and dyspareunia, which have a substantial impact on the lives of affected women, their partners, and families. SPIRIT 1 and 2 were phase 3, randomized, double-blind, placebo-controlled studies of once-daily relugolix CT (relugolix 40 mg, oestradiol 1 mg, norethisterone acetate 0.5 mg) in premenopausal women (age 18-50 years) with endometriosis and moderate-to-severe dysmenorrhea and NMPP. These trials demonstrated a significant improvement of dysmenorrhea, NMPP, and dyspareunia in women treated with relugolix CT, with minimal decline (<1%) in BMD versus placebo at 24 weeks. STUDY DESIGN, SIZE, DURATION: Patients participating in this open-label, single-arm, long-term extension (LTE) study of the 24-week SPIRIT pivotal studies (SPIRIT 1 and 2) received up to an additional 80 weeks of once-daily oral relugolix CT treatment between May 2018 and January 2023. PARTICIPANTS/MATERIALS, SETTING, METHODS: Premenopausal women with confirmed endometriosis and moderate to severe dysmenorrhea and NMPP who completed the 24-week pivotal studies (SPIRIT 1 and 2 trials; Giudice et al., 2022) and who met all entry criteria were eligible to enrol. Two-year results were analysed by treatment group based on original randomization in pivotal studies: relugolix CT, delayed relugolix CT (relugolix 40 mg monotherapy for 12 weeks, followed by relugolix CT), or placebo→relugolix CT (placebo for 24 weeks followed by relugolix CT). The primary endpoints of the LTE study were the proportion of dysmenorrhea and NMPP responders at Week 52 and Week 104/end-of-treatment (EOT). A responder was a participant who achieved a predefined, clinically meaningful reduction from baseline in Numerical Rating Scale (NRS) scores (0 = no pain, 10 = worst pain imaginable) for the specific pain type with no increase in analgesic use. The predefined clinically meaningful threshold for dysmenorrhea was 2.8 points and for NMPP was 2.1 points. Secondary efficacy endpoints included change from baseline in Endometriosis Health Profile-30 (EHP-30) pain domain scores, a measure of the effects of endometriosis-associated pain on daily activities (function), NRS scores for dysmenorrhea, NMPP, dyspareunia, and overall pelvic pain, and analgesic/opioid use. Safety endpoints included adverse events and changes in BMD. MAIN RESULTS AND THE ROLE OF CHANCE: Of 1261 randomized patients, 1044 completed the pivotal studies, 802 enrolled in the LTE, 681 completed 52 weeks of treatment, and 501 completed 104 weeks of treatment. Demographics and baseline characteristics of the extension population were consistent with those of the original randomized population. Among patients randomized to relugolix CT at pivotal study baseline who continued in the LTE (N = 277), sustained improvements in endometriosis-associated pain were demonstrated through 104 weeks. The proportion of responders at Week 104/EOT for dysmenorrhea and NMPP was 84.8% and 75.8%, respectively. Decreases in dyspareunia and improvement in function assessed by EHP-30 pain domain were also sustained over 2 years. At Week 104/EOT, 91% of patients were opioid-free and 75% of patients were analgesic-free. Relugolix CT over 104 weeks was well tolerated with a safety profile consistent with that observed over the first 24 weeks. After initial least squares mean BMD loss <1% at Week 24, BMD plateaued at Week 36 and was sustained for the duration of 104 weeks of treatment. Efficacy and safety results were generally consistent in women in the placebo→relugolix CT and delayed relugolix CT groups. LIMITATIONS, REASONS FOR CAUTION: The study was conducted as an open-label study without a control group over the 80 weeks of the extension period. Of the 802 patients who were enrolled in this LTE study, 681 patients (84.9%) and 501 patients (62.5%) of patients completed 52 and 104 weeks of treatment, respectively. In addition, there currently are no comparative data to other hormonal medications. Finally, a third (37.4%) of the study population terminated participation early. WIDER IMPLICATIONS OF THE FINDINGS: In conclusion, relugolix CT offers an additional option to help address an important unmet clinical need for effective, safe, and well-tolerated medical treatments for endometriosis that can be used longer-term, reducing the need for opioids and improving quality of life. The findings from this study may help support the care of women with endometriosis seeking longer-term effective medical management of their symptoms.

Vaginal atrophy and genital pain in women on depot medroxyprogesterone acetate contraceptive injection.

Depot medroxyprogesterone acetate causes a hypo-estrogenic state in over half of users although clinical vaginal atrophy causing superficial dyspareunia is thought rarely to occur. This is a case series of ten women using depot medroxyprogesterone acetate who presented with superficial dyspareunia and clinical vaginal atrophy. The women were treated with vaginal estriol cream and their contraception was discontinued or changed. All patients had either a complete resolution of symptoms or a substantial improvement at follow-up, and the clinical and laboratory findings of vaginal atrophy had resolved. This case series demonstrates that vaginal atrophy may occur more frequently than previously thought.

Hormonal Medications for Genitourinary Syndrome of Menopause.

Genitourinary syndrome of menopause is a common, under-reported, and undertreated chronic progressive condition requiring long-term treatment. Hypoestrogenism in the urogenital tissues is associated with bothersome dyspareunia, vulvovaginal symptoms, overactive bladder, and frequent urinary tract infections. Vaginal hormone therapies, including vaginal estrogen and intravaginal dehydroepiandrostenedione, are safe and effective and improve symptoms and clinical findings. Systemic hormone therapy treats vulvovaginal atrophy less effectively than vaginal hormone therapies with increased stress and urge urinary incontinence. Oral ospemifene effectively treats vaginal dryness and dyspareunia. Clinicians need to ask about symptoms of genitourinary syndrome of menopause, confirm the diagnosis, and suggest appropriate treatment options.

Pilot study of treatment of patients with deep infiltrative endometriosis with methotrexate carried in lipid nanoparticles.

OBJECTIVE: Previously, lipid nanoparticles (LDE) injected in women with endometriosis were shown to concentrate in the lesions. Here, the safety and feasibility of LDE carrying methotrexate (MTX) to treat deep infiltrating endometriosis was tested. DESIGN: Prospective pilot study. SETTING: Perola Byington Hospital Reference for Women's Health. SUBJECTS: Eleven volunteers (aged 30-47 years, BMI 26.15 ± 6.50 kg/m2) with endometriosis with visual analog scale pelvic pain scores (VAS) > 7 and rectosigmoid lesions were enrolled in the study. INTERVENTION: Three patients were treated with LDE-MTX at single intravenous 25 mg/m2 dose of MTX and eight patients with two 25 mg/m2 doses with 1-week interval. MAIN OUTCOME MEASURES: Clinical complaints, blood count, and biochemistry were analyzed before treatment and on days 90, 120, and 180 after LDE-MTX administration. Endometriotic lesions were evaluated by pelvic and transvaginal ultrasound (TVUS) before treatment and on days 30 and 180 after LDE-MTX administration. RESULTS: No clinical complaints related with LDE-MTX treatment were reported by the patients, and no hematologic, renal, or hepatic toxicities were observed in the laboratorial exams. FSH, LH, TSH, free T4, anti-Müllerian hormone, and prolactin levels were also within normal ranges during the observation period. Scores for deep dyspareunia (p < 0.001), chronic pelvic pain (p = 0.008), and dyschezia (p = 0.025) were improved over the 180-day observation period. There was a non-significant trend for reduction of VAS scores for dysmenorrhea. Bowel lesions by TVUS were unchanged. No clear differences between the two dose levels in therapeutic responses were observed. CONCLUSION: Results support the safety and feasibility of using LDE-MTX in women with deep infiltrating endometriosis as a novel and promising therapy for the disease. More prolonged treatment schemes should be tested in future placebo-controlled studies aiming to establish the usefulness of this novel nanomedicine approach.

Managing Menopausal Symptoms: Common Questions and Answers.

Menopausal symptoms are widespread and significantly impact quality of life. Common symptoms of menopause are vasomotor (i.e., hot flashes and night sweats) and genitourinary (e.g., vulvovaginal irritation and dryness, dyspareunia, urinary problems), although women may also experience changes in sexual function, mood, and sleep. Estrogen-containing hormone therapy is effective treatment for vasomotor symptoms. Nonhormonal medications for vasomotor symptoms include selective serotonin reuptake inhibitors, serotonin-norepinephrine reuptake inhibitors, and gabapentin. Selective serotonin reuptake inhibitors should not be administered to women taking tamoxifen. Cognitive behavior therapy and clinical hypnosis are effective for short-term reduction of vasomotor symptoms and associated sleep disturbances, but data are lacking to support the effectiveness of other nonpharmacologic treatments such as herbal or botanicalsupplements, exercise, and acupuncture. Hormone-free vaginal moisturizers are noninferior to estrogen-based therapies for treating genitourinary syndrome of menopause. Other treatment options for vaginal dryness and dyspareunia associated with menopause include ospemifene and intravaginal dehydroepiandrosterone. Management of menopausal symptoms should involve shared decision-making that is informed by the best available evidence and individual risks and preferences.

Topical estrogens for the treatment of superficial dyspareunia related to genitourinary syndrome of menopause in women with a history of endometriosis: A clinical dilemma.

Estrogen withdrawal, which occurs with the cessation of ovulation, causes genitourinary syndrome of menopause in up to 50-85% of women. Symptoms may profoundly impact quality of life and sexual function, interfering with enjoyment of sex in up to three out of four individuals. Topical estrogens have been found to provide symptom relief with minimal systemic absorption and appear to be superior to systemic therapy as what regards genitourinary symptoms. However, conclusive data on their appropriateness in postmenopausal women with a history of endometriosis is not available and the hypothesis that exogenous estrogen stimulation may reactivate endometriotic foci or even promote their malignant transformation is still open. On the other hand, endometriosis affects around 10% of premenopausal women, many of which may be exposed to an acute hypoestrogenic depletion even before spontaneous menopause occurs. This considered, excluding on principle patients with a history of endometriosis from first-line treatment for vulvovaginal atrophy would mean excluding a considerable percentage of the population from adequate care. More robust evidence is urgently needed in these regards. Meanwhile, it would appear reasonable to tailor the prescription of topical hormones in these patients, taking into account the entity of symptoms and the impact such symptoms have on patients' quality of life, as well as the form of endometriosis and the possible risks hormonal may entail. Moreover, the application of estrogens on the vulva instead of the vagina could be efficacious, while outweighing the possible biological cost of hormonal treatment in women with a history of endometriosis.

Gonadotropin-releasing hormone analogues for endometriosis.

BACKGROUND: Endometriosis is a common gynaecological condition affecting 6 to 11% of reproductive-age women and may cause dyspareunia, dysmenorrhoea, and infertility. One treatment strategy is medical therapy with gonadotrophin-releasing hormone analogues (GnRHas) to reduce pain due to endometriosis. One of the adverse effects of GnRHas is a decreased bone mineral density. In addition to assessing the effect on pain, quality of life, most troublesome symptom and patients' satisfaction, the current review also evaluated the effect on bone mineral density and risk of adverse effects in women with endometriosis who use GnRHas versus other treatment options. OBJECTIVES: To assess the effectiveness and safety of GnRH analogues (GnRHas) in the treatment of painful symptoms associated with endometriosis and to determine the effects of GnRHas on bone mineral density of women with endometriosis. SEARCH METHODS: We searched the Cochrane Gynaecology and Fertility (CGF) Group trials register, CENTRAL, MEDLINE, Embase, PsycINFO and the trial registries in May 2022 together with reference checking and contact with study authors and experts in the field to identify additional studies. SELECTION CRITERIA: We included randomised controlled trials (RCTs) which compared GnRHas with other hormonal treatment options, including analgesics, danazol, intra-uterine progestogens, oral or injectable progestogens, gestrinone and also GnRHas compared with no treatment or placebo. Trials comparing GnRHas versus GnRHas in conjunction with add-back therapy (hormonal or non-hormonal) or calcium-regulation agents were also included in this review.  DATA COLLECTION AND ANALYSIS: We used standard methodology as recommended by Cochrane. Primary outcomes are relief of overall pain and the objective measurement of bone mineral density. Secondary outcomes include adverse effects, quality of life, improvement in the most troublesome symptoms and patient satisfaction.  Due to high risk of bias associated with some of the studies, primary analyses of all review outcomes were restricted to studies at low risk of selection bias. Sensitivity analysis including all studies was then performed. MAIN RESULTS: Seventy-two studies involving 7355 patients were included. The evidence was very low to low quality: the main limitations of all studies were serious risk of bias due to poor reporting of study methods, and serious imprecision.  Trials comparing GnRHas versus no treatment  We did not identify any studies. Trials comparing GnRHas versus placebo There may be a decrease in overall pain, reported as pelvic pain scores (RR 2.14; 95% CI 1.41 to 3.24, 1 RCT, n = 87, low-certainty evidence), dysmenorrhoea scores (RR 2.25; 95% CI 1.59 to 3.16, 1 RCT, n = 85, low-certainty evidence), dyspareunia scores (RR 2.21; 95% CI 1.39 to 3.54, 1 RCT, n = 59, low-certainty evidence), and pelvic tenderness scores (RR 2.28; 95% CI 1.48 to 3.50, 1 RCT, n = 85, low-certainty evidence) after three months of treatment. We are uncertain of the effect for pelvic induration, based on the results found after three months of treatment (RR 1.07; 95% CI 0.64 to 1.79, 1 RCT, n = 81, low-certainty evidence). Besides, treatment with GnRHas may be associated with a greater incidence of hot flushes at three months of treatment (RR 3.08; 95% CI 1.89 to 5.01, 1 RCT, n = 100, low-certainty evidence). Trials comparing GnRHas versus danazol For overall pain, for women treated with either GnRHas or danazol, a subdivision was made between pelvic tenderness, partly resolved and completely resolved. We are uncertain about the effect on relief of overall pain, when a subdivision was made for overall pain (MD -0.30; 95% CI -1.66 to 1.06, 1 RCT, n = 41, very low-certainty evidence), pelvic pain (MD 0.20; 95% CI -0.26 to 0.66, 1 RCT, n = 41, very low-certainty evidence), dysmenorrhoea (MD 0.10; 95% CI -0.49 to 0.69, 1 RCT, n = 41, very low-certainty evidence), dyspareunia (MD -0.20; 95% CI -0.77 to 0.37, 1 RCT, n = 41, very low-certainty evidence), pelvic induration (MD -0.10; 95% CI -0.59 to 0.39, 1 RCT, n = 41, very low-certainty evidence), and pelvic tenderness (MD -0.20; 95% CI -0.78 to 0.38, 1 RCT, n = 41, very low-certainty evidence) after three months of treatment. For pelvic pain (MD 0.50; 95% CI 0.10 to 0.90, 1 RCT, n = 41, very low-certainty evidence) and pelvic induration (MD 0.70; 95% CI 0.21 to 1.19, 1 RCT, n = 41, very low-certainty evidence), the complaints may decrease slightly after treatment with GnRHas, compared to danazol, for six months of treatment. Trials comparing GnRHas versus analgesics  We did not identify any studies. Trials comparing GnRHas versus intra-uterine progestogens We did not identify any low risk of bias studies. Trials comparing GnRHas versus GnRHas in conjunction with calcium-regulating agents There may be a slight decrease in bone mineral density (BMD) after 12 months treatment with GnRHas, compared to GnRHas in conjunction with calcium-regulating agents for anterior-posterior spine (MD -7.00; 95% CI -7.53 to -6.47, 1 RCT, n = 41, very low-certainty evidence) and lateral spine (MD -12.40; 95% CI -13.31 to -11.49, 1 RCT, n = 41, very low-certainty evidence).  AUTHORS' CONCLUSIONS: For relief of overall pain, there may be a slight decrease in favour of treatment with GnRHas compared to placebo or oral or injectable progestogens. We are uncertain about the effect when comparing GnRHas with danazol, intra-uterine progestogens or gestrinone. For BMD, there may be a slight decrease when women are treated with GnRHas, compared to gestrinone. There was a bigger decrease of BMD in favour of GnRHas, compared to GnRHas in conjunction with calcium-regulating agents. However, there may be a slight increase in adverse effects when women are treated with GnRHas, compared to placebo or gestrinone. Due to a very low to low certainty of the evidence, a wide range of outcome measures and a wide range of outcome measurement instruments, the results should be interpreted with caution.

Investigating the efficacy of ultrasound-guided ethanol retention technique for endometrioma sclerotherapy and its effect on pro-inflammatory cytokine levels: A single-arm clinical trial.

BACKGROUND: Endometriosis is a chronic inflammatory disease affecting about 10% of women of reproductive age. Endometrioma is the most common presentation of endometriosis in ovaries. OBJECTIVES: Herein, the authors study the effect of the ultrasound-guided ethanol retention technique for endometrioma sclerotherapy and its effect on the plasma levels of pro-inflammatory cytokines. MATERIALS AND METHODS: Each endometrioma was aspirated and washed with 0.9% saline until clearance and then 2/3 of the cyst volume was filled with ethanol 98%. Patients were followed for 3 months. After that, changes in their cyst diameter, dyspareunia, dysmenorrhea, and antral follicular count were assessed. Also, the sera levels of Interleukin 1ß (IL-ß), IL-6, and IL-8 were assayed before and after the treatment. The primary sera levels were also compared with a control group. RESULTS: In the treatment and control groups, 23 and 25 individuals (respectively) with a matched mean age (p-value = 0.680) were enrolled in the study. Among the laboratory variables, IL-1ß (p-value = 0.035), as well as AMH (p-value = 0.002), were lower, and IL-6 (p-value = 0.011) was higher in the endometriosis group compared to the controls. Following the treatment, dysmenorrhea, dyspareunia, and the mean diameter of all cysts were significantly (p-values < 0.001) decreased in the treatment group. Also, right (p-value = 0.022) and left (p-value = 0.002) ovaries' antral follicular counts were increased following the treatment. No significant change was found among any of the investigated laboratory levels (p-value > 0.05). CONCLUSION: Ethanol retention method is proven to be safe and could improve the clinical status of patients with endometrioma. Although further studies are necessary.

Pharmacokinetics, safety and preliminary pharmacodynamic evaluation of DARE-VVA1: a soft gelatin capsule containing tamoxifen for the treatment of vulvovaginal atrophy.

OBJECTIVE: This study aimed to measure safety, systemic pharmacokinetics and preliminary efficacy of a vaginal tamoxifen capsule (DARE-VVA1) among postmenopausal women with moderate-to-severe vulvovaginal atrophy. METHODS: This was a randomized, placebo-controlled, double-blind, phase 1/2 study of DARE-VVA1, in four doses (1, 5, 10 and 20 mg). RESULTS: Seventeen women were enrolled and 14 completed the 8-week treatment. DARE-VVA1 was safe. All adverse events were of mild or moderate severity and distributed similarly among active and placebo groups. Plasma tamoxifen concentrations were highest among women using DARE-VVA1 20 mg, but the maximum mean (standard deviation) plasma tamoxifen concentrations on day 1 (2.66 ± 0.85 ng/ml) and day 56 (5.69 ± 1.87 ng/ml) were <14% of those measured after one oral tamoxifen dose. Active study product users had significant decreases from pre-treatment baseline in vaginal pH and proportion of vaginal parabasal cells (p = 0.04 for both endpoints), with women randomized to the 10 mg or 20 mg dose experiencing the largest treatment impact. The severity of vaginal dryness and dyspareunia decreased significantly from baseline with active study product use (p = 0.02 for both endpoints). CONCLUSIONS: DARE-VVA1 is safe and results in minimal systemic exposure to tamoxifen. Preliminary efficacy data support further development of this product.

The vagina as source and target of androgens: implications for treatment of GSM/VVA, including DHEA.

The vagina is traditionally thought of as a passive organ in the female reproductive system, serving primarily as a passageway for menstrual blood, sexual intercourse and childbirth. However, recent research has shed light on the vagina's role as an endocrine organ that plays a crucial role in female hormonal balance and overall health. Particularly, growing evidence shows that the human vagina can be considered both as source and target of androgens, in view of the novel concept of 'intracrinology'. Besides the well-known role of estrogens, androgens are also crucial for the development and maintenance of healthy genitourinary tissues in women. As androgen levels decline with age, and estrogen levels fall during the menopausal transition, the tissues in the vagina, together with those in the urinary tract, become thinner, drier and less elastic, leading to a variety of uncomfortable and sometimes painful symptoms, clustered in the genitourinary syndrome of menopause (GSM). Given the lack of testosterone-based or androstenedione-based products approved by regulatory agencies to treat GSM, the possibility of using intravaginal prasterone, which works by providing a local source of dehydroepiandrosterone (DHEA) to the vaginal tissues, appears to be a targeted treatment. Further studies are needed to better assess its safety and efficacy.

Different local estrogen therapies for a tailored approach to GSM.

Local estrogen therapy (LET) is the mainstay of treatment for vaginal dryness, dyspareunia and other urogenital symptoms because it may reverse some pathophysiological mechanisms associated with decreasing endocrine function and increasing aging. Over the years, several vaginal products including different formulations (tablets, rings, capsules, pessaries, creams, gels and ovules) and molecules (estradiol [E2], estriol [E3], promestriene, conjugated equine estrogens and estrone) have been used with superimposable therapeutic results. Low-dose and ultra-low-dose LET is the gold standard due to its minimal systemic absorption, with circulating E2 levels persistently remaining in the postmenopausal range. In healthy postmenopausal women, preference among the various products is presently the main driver and dissatisfaction with LET seems high, namely because of the delayed use in those with severe symptoms of genitourinary syndrome of menopause (GSM). Specific concerns remain in high-risk populations such as breast cancer survivors (BCS), especially those under treatment with aromatase inhibitors. Based on the multitude of symptoms under the umbrella of GSM definition, which includes vulvovaginal atrophy (VVA), it is mandatory to investigate specific effects of LET on quality of life, sexual function and genitourinary conditions by conducting studies with a patient-tailored focus.

Efficacy, tolerability, and endometrial safety of ospemifene compared with current therapies for the treatment of vulvovaginal atrophy: a systematic literature review and network meta-analysis.

IMPORTANCE: Ospemifene is a novel selective estrogen receptor modulator developed for the treatment of moderate to severe postmenopausal vulvovaginal atrophy (VVA). OBJECTIVE: The aim of the study is to perform a systematic literature review (SLR) and network meta-analysis (NMA) to assess the efficacy and safety of ospemifene compared with other therapies used in the treatment of VVA in North America and Europe. EVIDENCE REVIEW: Electronic database searches were conducted in November 2021 in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Randomized or nonrandomized controlled trials targeting postmenopausal women with moderate to severe dyspareunia and/or vaginal dryness and involving ospemifene or at least one VVA local treatment were considered. Efficacy data included changes from baseline in superficial and parabasal cells, vaginal pH, and the most bothersome symptom of vaginal dryness or dyspareunia, as required for regulatory approval. Endometrial outcomes were endometrial thickness and histologic classifications, including endometrial polyp, hyperplasia, and cancer. For efficacy and safety outcomes, a Bayesian NMA was performed. Endometrial outcomes were compared in descriptive analyses. FINDINGS: A total of 44 controlled trials met the eligibility criteria ( N = 12,637 participants). Network meta-analysis results showed that ospemifene was not statistically different from other active therapies in most efficacy and safety results. For all treatments, including ospemifene, the posttreatment endometrial thickness values (up to 52 wk of treatment) were under the recognized clinical threshold value of 4 mm for significant risk of endometrial pathology. Specifically, for women treated with ospemifene, endometrial thickness ranged between 2.1 and 2.3 mm at baseline and 2.5 and 3.2 mm after treatment. No cases of endometrial carcinoma or hyperplasia were observed in ospemifene trials, nor polyps with atypical hyperplasia or cancer after up to 52 weeks of treatment. CONCLUSIONS AND RELEVANCE: Ospemifene is an efficacious, well-tolerated, and safe therapeutic option for postmenopausal women with moderate to severe symptoms of VVA. Efficacy and safety outcomes with ospemifene are similar to other VVA therapies in North America and Europe.

Uterine botulinum toxin injections in severe dysmenorrhea, dyspareunia and chronic pelvic pain: Results on quality of life, pain level and medical consumption.

OBJECTIVE: To evaluate quality of life (Qol), pain level and medical consumption before and after uterine botulinum toxin (BT) injections in severe dysmenorrhea, dyspareunia and chronic pelvic pain. METHODS: This was a before and after study using the database of a pilot study (Open-label non comparative study, on 30 patients, with severe dysmenorrhoea in therapeutic failure) assessing efficacy and cost of uterine injection of BT in women with chronic pelvic pain after failure of conventional treatment (hormonal and analgesics) (CT). Main clinical outcome: Patient Global Impression of Improvement (PGI-I), EuroQol health-related QoL (EQ-5D-5L), EuroQol-visual analogue scale (EQ-VAS), Female Sexual Function Index (FSFI), utility measure of health-related quality of life (also called health state preference values), cost and of health care consumption were collected prospectively and analysed in the two phases (before and after). The two timepoints were 12 months before uterine BT injection, when the patient had been receiving CT, and 12 months after uterine BT injection. RESULTS: Median visual analogue scale scores were significantly improved by BT regarding the patients' main source of pain (31.6 vs 80.55; p < 0.00001). We also noted a significant reduction in the proportion of patients who reported dyspareunia [15 (75%) vs 3 (15%) patients, p = 0.001] and pain during menstruation (p < 0.0001). The PGI-I scale showed a significant increase in the proportion of patients who were satisfied with their treatment after receiving the BT injection. The injection of BT was frequently associated with increase in QoL and a reduction in health care consumption, and cost: 714.82 €+/- €336.43 (BT) versus 1104.16 €+/- €227.37 (CT), which could result in substantial savings approximately (389,34€) per patient. CONCLUSION: This study revealed the clinical effectiveness of BT injections on dysmenorrhea, chronic pelvic pain as well as reduction of cost and health care consumption, in our population, which is innovative since no standard of treatment exists in this domain.

Effects of preoperative intravaginal estrogen on pelvic floor disorder symptoms in postmenopausal women with pelvic organ prolapse.

BACKGROUND: Menopause and the decline in systemic estrogen are associated with the development of pelvic floor disorders, such as prolapse, urinary incontinence, overactive bladder, and vulvovaginal atrophy symptoms. Past evidence suggests that postmenopausal women with symptomatic prolapse gain benefit from the preoperative application of intravaginal estrogen, but it is unknown whether they would experience improvement in other pelvic floor symptoms when treated with intravaginal estrogen. OBJECTIVE: This study aimed to determine the effects of intravaginal estrogen (compared with placebo) on stress and urgency urinary incontinence, urinary frequency, sexual function and dyspareunia, and vaginal atrophy symptoms and signs in postmenopausal women with symptomatic prolapse. STUDY DESIGN: This was a planned ancillary analysis of a randomized, double-blind trial, "Investigation to Minimize Prolapse Recurrence Of the Vagina using Estrogen," which included participants with ≥stage 2 apical and/or anterior prolapse scheduled for transvaginal native tissue apical repair at 3 US sites. The intervention was 1 g conjugated estrogen intravaginal cream (0.625 mg/g) or identical placebo (1:1), inserted nightly for 2 weeks and then twice weekly for ≥5 weeks total before surgery and continued twice weekly for 1 year postoperatively. For this analysis, question responses were compared from participants' baseline and preoperative visits: lower urinary tract symptoms (Urogenital Distress Inventory-6 Questionnaire); sexual health questions, including dyspareunia (Pelvic Organ Prolapse/Incontinence Sexual Function Questionnaire-IUGA-Revised); and atrophy-related symptoms (dryness, soreness, dyspareunia, discharge, and itching; each scored 1-4, 4 being quite a bit bothersome). Masked examiners assessed vaginal color, dryness, and petechiae (each scored 1-3, total range 3-9, with 9 being the most estrogenized appearing). Data were analyzed by intent to treat and "per protocol" (ie, those adherent with ≥50% of expected intravaginal cream use, per objective tube before and after weights). RESULTS: Of 199 participants randomized (mean age of 65 years) and contributing baseline data, 191 had preoperative data. The characteristics were similar between groups. Total Urogenital Distress Inventory-6 Questionnaire scores showed minimal change during this median time of 7 weeks between baseline and preoperative visits, but for those with at least moderately bothersome baseline stress urinary incontinence (32 in the estrogen group and 21 in the placebo group), 16 (50%) in the estrogen group and 9 (43%) in the placebo group showed improvement (P=.78). In addition, 43% of participants in the estrogen group and 31% of participants in the placebo group showed improvement in urgency urinary incontinence (P=.41), and 41% of participants in the estrogen group and 26% of participants in the placebo group showed improvement in urinary frequency (P=.18). There was minimal change in the Pelvic Organ Prolapse/Incontinence Sexual Function Questionnaire-IUGA-Revised scores among sexually active women; dyspareunia rates did not differ between intravaginal estrogen and placebo at the preoperative assessment: 42% and 48%, respectively (P=.49). The maximum score for most bothersome atrophy symptom (among those with baseline symptoms and adherent to study cream) improved slightly more with intravaginal estrogen (adjusted mean difference, -0.33 points; 95% confidence interval, -0.98 to 0.31), but this was not statistically significant (P=.19). However, on examination, among adherent participants, objective signs of atrophy were more improved with intravaginal estrogen treatment (+1.54 vs +0.69; mean difference, 0.85; 95% confidence interval, 0.05-1.65; P=.01). CONCLUSION: Despite objective changes in the vaginal epithelium consistent with increased estrogenization among drug-adherent participants, the results were inconclusive regarding whether 7 weeks of preoperative intravaginal estrogen cream in postmenopausal women with symptomatic pelvic organ prolapse was associated with improved urinary function, sexual function, dyspareunia symptoms, and other symptoms commonly attributed to atrophy. Additional study is needed.

Satisfaction and medication adherence in women with vulvovaginal atrophy: the CRETA.

OBJECTIVE: This study aimed to evaluate the self-reported satisfaction of Spanish postmenopausal women currently treated for vulvovaginal atrophy (VVA) symptoms. METHODS: The CRETA (CRoss sectional European sTudy on Adherence) is a multicenter cross-sectional study conducted in 29 public and private hospitals in Spain, which enrolled postmenopausal women receiving treatment with ospemifene, local hormone therapy (HT) or vaginal moisturizers for VVA. After the prior informed consent of the patients, sociodemographic and treatment perception data were collected using a structured questionnaire. RESULTS: Among 752 women who completed the survey, the satisfaction score was significantly higher for the group treated with ospemifene (mean 8.3 ± 1.4) compared with the local HT group (7.2 ± 1.7) and the vaginal moisturizer group (6.5 ± 2.1) according to a 10-point Likert scale (p < 0.0001). Compared to vaginal moisturizers and local HT, participants treated with ospemifene reported the highest adherence (96.7% vs. 70.2% and 78.6%, respectively) and the lowest number of missed doses in the last month (0.6 ± 1.3 standard deviation [SD] vs. 3.5 ± 4.3 SD and 2.0 ± 2.8 SD, respectively) (p < 0.0001). Ospemifene was significantly perceived as easy to use (83.9% vs. 44.9% and 58.6%, respectively; p < 0.0001), efficacious in reducing the time to relieve symptoms (17.1% vs. 7.0% and 6.7%, p = 0.0005 and p = 0.0006, respectively) and convenient for sexual life (53.1% vs. 25.6% and 42.3%, p < 0.0001 and p = 0.0234, respectively). CONCLUSIONS: Among postmenopausal women with VVA, treatment with ospemifene has the most positive perceptions and the highest overall satisfaction level and could be an optimal therapeutic approach, maximizing patient adherence.

Expert opinion on the treatment of vulvovaginal atrophy with ospemifene based on new evidence.

Vulvovaginal atrophy (VVA) is an underdiagnosed and undertreated chronic condition resulting in physiological and histological changes in the genitourinary tract of postmenopausal women. Treatment of moderate to severe VVA includes local estrogens, dehydroepiandrosterone (DHEA) and oral ospemifene, a third-generation selective estrogen receptor modulator (SERM). Due to venous thromboembolism (VTE) safety concerns classically associated with the SERM class, and as part of its original marketing authorization approval (MAA), the European Medicines Agency (EMA) requested the performance of a 5-year post-authorization safety study (PASS) to study the incidence rate of VTE among women receiving ospemifene. The results have led to important regulatory changes to ospemifene's labeling, extending its indication and eliminating concerted risk management measures. A panel of experts discussed and reached consensus on the impact of these regulatory changes on clinical practice, reflecting on the reassurance of ospemifene's benefit-risk balance and recommending its positioning as a first-line pharmacological treatment option for moderate to severe VVA together with local therapies. In a scenario where different treatments present similar efficacy and safety profiles, a shared decision between clinician and patient, according to her needs and preferences over time, is fundamental to improve adherence and persistence with sequential treatment, contributing to the achievement of health outcomes.

Sequential treatment in vulvovaginal atrophy.

Vulvovaginal atrophy (VVA) is a chronic and progressive disease that affects sexuality and quality of life. VVA is preventable and treatable, but requires long-term and often sequential treatment. Sequential treatment consists of designing a strategy that uses one or more medications for a long enough time to achieve the desired benefits with minimal risk and maximum adherence. Currently available therapeutic options consist of topical over-the-counter products (including non-hormonal lubricants and moisturizers applied to the vagina), systemic hormone therapy and estrogens, and prescribed vaginal dehydroepiandrosterone (DHEA). In addition, we have a selective estrogen receptor modulator, ospemifene, and new energy-based treatments (laser and radiofrequency). There are clear differences between the treatments both in the mechanism of action and in the efficacy. Compliance is very low, and patients complain about the use of the vaginal route, often due to its low efficacy, or express fear of the long-term use of estrogens or the price of the treatments. We believe that, as a first option, and for physiological, preventive and efficacy reasons, we should consider the prescription of treatments that work on estrogen receptors. As a second option, there are vaginal moisturizers, which are effective on symptoms but do not prevent or improve conditions. Finally, techniques using heat, which although each time represent a clearer alternative, but on the other hand are the cost and the long-term safety data, give us a third option. Of course, we consider that vulvar moisturizers and lubricants can be used at any time.
