The complexity of genitourinary syndrome of menopause: number, severity, and frequency of vulvovaginal discomfort symptoms in women enrolled in a randomized trial evaluating treatment for genitourinary syndrome of menopause

Laser for genitourinary syndrome of menopause: what we know and what we need to know

Energy-based treatments, including the fractional CO2 laser, have been widely used for treatment of genitourinary symptoms associated with menopause. With the availability of data from seven double-blind sham-controlled randomized trials, the evidence does not support the fractional CO2 laser as an efficacious treatment for genitourinary syndrome of menopause (GSM). A 2024 meta-analysis of these trials demonstrated that the symptom with greatest absolute improvement was dyspareunia at 16.3%, although not statistically significant. This improvement is far less than previously anticipated based on prospective data that suggested promising improvements of more than 90% satisfaction following laser treatment. Other data, including those from unblinded studies which are subject to a placebo effect, and outcomes that are not participant-reported including the appearance of the vagina on examination and histology, are not reliable in determining efficacy of laser treatment for GSM. While there may be a clinical effect of laser over sham treatments for GSM, the effect is unlikely to be clinically meaningful. Until we define and demonstrate a minimal clinically important difference in a robust and appropriately powered study, the laser should not be used in a clinical context for GSM.

Hyaluronic acid and erbium laser for the treatment of genitourinary syndrome of menopause

OBJECTIVE

This study aimed to evaluate the effect of the vaginal erbium laser (VEL) in association with vaginal hyaluronic acid (HA) in postmenopausal women suffering from genitourinary syndrome of menopause (GSM).

METHODS

One hundred sexually active postmenopausal women were selected and divided into three groups using a block randomization method; 10 women declined to participate. The remaining women received three laser applications at 30-day intervals; 22 women dropped out for personal reasons or protocol violations. Group 1 (n = 25) received VEL treatment (XS Fotona Smooth®; Fotona, Slovenia) alone; Group 2 (n = 22) received daily vaginal HA tablets for 10 days after VEL treatment, followed by a twice a week administration during the follow-up period; and Group 3 (n = 21) received daily HA tablets for 10 days before the first VEL treatment and for 10 days after each laser application, followed by a twice a week administration for the follow-up period. Vaginal dryness and dyspareunia were assessed at the screening visit, before VEL treatment, after 1 and 3 months from the last laser treatment, using the visual analog scale. Data were analyzed using one-way analysis of variance and a linear mixed model for repeated measures. The post-hoc test for the interaction between time and treatment was performed using Bonferroni correction.

RESULTS

A significant (p < 0.001) improvement in both vaginal dryness and superficial dyspareunia was evident, with greater (p < 0.001) improvement in Group 2 and Group 3.

CONCLUSIONS

The results suggest that vaginal HA administration can improve the VEL effects on GSM in postmenopausal women.

Insights into the vulvar component of the genitourinary syndrome of menopause (GSM)

Genitourinary syndrome of menopause is a comprehensive term that groups genital, urinary and sexual signs and symptoms mainly due sex hormone deficiency and aging, with a crucial impact on quality of life of midlife women. While this broad definition captures the common underlying physiopathology and the frequent overlap of symptomatology, improving knowledge about different components of genitourinary syndrome of menopause may be relevant for individualized treatment, with possible implications for efficacy, compliance and satisfaction. This narrative review focuses on the vulvar component of genitourinary syndrome of menopause, highlighting anatomical and functional peculiarities of the vulva that are responsible for some of the self-reported symptoms, as well as specific signs at physical examination. Increasing evidence points towards a pivotal role of vulvar vestibular health in the occurrence of sexual pain, one of the most common and distressing symptoms of genitourinary syndrome of menopause, which should be evaluated with validated scales taking a biopsychosocial perspective. This is an essential step in the recognition of different phenotypes of genitourinary syndrome of menopause and in the assessment of the most effective diagnostic and therapeutic algorithm. Menopausal vulvar health deserves more research into tailored non-hormonal and hormonal treatment options.

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.

Oral lasofoxifene's effects on moderate to severe vaginal atrophy in postmenopausal women: two phase 3, randomized, controlled trials

OBJECTIVE

The aim of this study was to demonstrate whether lasofoxifene improves vaginal signs/symptoms of genitourinary syndrome of menopause.

METHODS

Two identical, phase 3 trials randomized postmenopausal women with moderate to severe vaginal symptoms to oral lasofoxifene 0.25 or 0.5 mg/d, or placebo, for 12 week. Changes from baseline to week 12 in most bothersome symptom, vaginal pH, and percentages of vaginal parabasal and superficial cells were evaluated. These coprimary endpoints were analyzed using analysis of covariance, except superficial cells, which were analyzed by the nonparametric, rank-based Kruskal-Wallis test.

RESULTS

The two studies enrolled 444 and 445 women (mean age, ~60 y), respectively. Coprimary endpoints at week 12 improved with lasofoxifene 0.25 and 0.5 mg/d greater than with placebo ( P < 0.0125 for all). Study 1: most bothersome symptom (least square mean difference from placebo: -0.4 and -0.5 for 0.25 and 0.5 mg/d, respectively), vaginal pH (-0.65, -0.58), and vaginal superficial (5.2%, 5.4%), and parabasal (-39.9%, -34.9%) cells; study 2: most bothersome symptom (-0.4, -0.5), vaginal pH (-0.57, -0.67), and vaginal superficial (3.5%, 2.2%) and parabasal (-34.1%, -33.5%) cells. Some improvements occurred as early as week 2. Most treatment-emergent adverse events were mild or moderate and hot flushes were most frequently reported (lasofoxifene vs placebo: 13%-23% vs 9%-11%). Serious adverse events were infrequent and no deaths occurred.

CONCLUSIONS

In two phase 3 trials, oral lasofoxifene 0.25 and 0.5 mg/d provided significant and clinically meaningful improvements in vaginal signs/symptoms with a favorable safety profile, suggesting beneficial effects of lasofoxifene on genitourinary syndrome of menopause.

Sexual Dysfunction After Menopause: Guidelines for Assessment and Management

Female sexual dysfunction commonly occurs during the menopause transition and post-menopause due to hormonal, physiologic, and psychosocial factors. Sexuality is important to aging women; however, many are reluctant to seek treatment for their sexual concerns. Clinicians should be adept at managing and treating sexual dysfunction in this population. A multi-dimensional treatment approach that addresses modifiable mental, physical, and psychosocial factors is warranted to improve sexual function and quality of life.

Genitourinary Syndrome of Menopause: Pathophysiology, Clinical Presentation, and Differential Diagnosis

Scientific information is incomplete regarding the genitourinary syndrome of menopause. Both the lower genital and urinary tracts are rich in receptors for reproductive hormones and are highly susceptible to waning ovarian hormones at menopause. Symptoms of dryness and pain emerge in late perimenopause, but they can also result earlier from cancer therapies or bilateral oophorectomy. Lower urinary tract symptoms rise in prevalence at midlife and increase further with advancing age. Because ovarian senescence is typically followed by years of aging, some postmenopausal complaints may be attributable to increasing longevity.

Genitourinary Syndrome of Menopause: Does Everyone Have It?

In 2014, the North American Menopause Society and the International Society for the Study of Women's Sexual Health recommended using the term genitourinary syndrome of menopause (GSM) to cover a range of genital and urinary symptoms that might be experienced during and after menopause. The term as currently defined, however, includes symptoms that may not be menopausal symptoms. The term GSM also includes "objective" measures such as vaginal pH that do not relate to symptom severity and are not priorities for clinicians or patients. We question the validity of GSM as a new syndrome and recommend the definition of the syndrome be revised to ensure it more closely reflects the symptoms attributable to menopause and the experience, difficulties, and response to treatment of those affected.
