Genitourinary Syndrome of Menopause: New Name, Old Problem
Previously known as atrophic vaginitis, vulvovaginal atrophy (VVA), or urogenital atrophy, genitourinary syndrome of menopause (GSM) is a composite of genital, urologic and sexual sequelae of chronic hypoestrogenism. Sexual dysfunction and quality of life impairment are important to identify, as treatment options are available. Incidence is unknown as the syndrome is often underreported by women due to embarrassment, disregard, or a sense of inevitability.
KEY POINTS:
Risk Factors
Lactation
Hyperprolactinemia
Autoimmune disorders
Bilateral oophorectomy
Pelvic radiation
Chemotherapy
Medications including
GnRH agonists (leuprolide, nafarelin)
SERMs (such as tamoxifen)
Aromatase inhibitors,
Danazol
Progestins
Lifestyle risk factors including
Cigarette smoking, Alcohol abuse | Sexual abstinence | Lack of exercise | Lack of vaginal birth
Local Estrogen Treatment Options for Vaginal Atrophy
CLINICAL ACTIONS:
A growing number of estrogen treatment options are available for postmenopausal vaginal atrophy. Vulvovaginal atrophy is a common symptom of atrophic vaginitis (also referred to as the genitourinary syndrome of menopause or GSM) and can occur in both perimenopausal and postmenopausal women. If a patient reports vaginal dryness, consider the following
Establish a diagnosis of postmenopausal atrophy based on thorough history and physical exam
Confirm with an appropriate pelvic/ vaginal exam
Discuss use of estrogen, understanding that for some women based on medical history, systemic estrogen might not be an appropriate option
Even with a personal history of cancer, local estrogen may be an appropriate treatment (see ‘Key Points’ and ‘Related ObG Topics’ below) depending on the clinical scenario
Vaginal estrogens can be prescribed as
A cream inserted twice weekly using an applicator
A tablet inserted with an applicator
A soft gel pellet inserted twice weekly with no applicator (FDA approved May, 2018)
Ring made of silicone elastomere containing a drug core of estradiol hemihydrate (replaced every 3 months)
Local Estrogen Routes and Dosing for GSM
Estradiol-17β ring (releases 7.5 micrograms/d)
Replace every 3 months
Estradiol vaginal tablet (10 micrograms/d)
Place nightly for 2 weeks
Maintenance is one tablet 2 times/week
Note: this is the corrected dose in ACOG PB 141
Estradiol-17β cream (0.1 mg active ingredient/g)
2-4 g/d for 1 to 2 weeks
Gradually reduce to ½ initial dosage for 1 – 2 weeks
Maintenance is 1 g, 1 to 3 times/week
Conjugated estrogen cream (0.625 mg/g)
0.5–2 g/d for 21 days then off for 7 days
In practice during maintenance therapy, most women apply 1 – 3 times /week
Vaginal inserts (4-μg and 10-μg)
1 vaginal insert daily for 2 weeks
Maintenance is 1 insert twice weekly
SYNOPSIS:
Patients may experience vaginal atrophy as itching, dryness or pain during sexual activity. Vaginal estrogen has been shown to improve moderate to severe menopausal vaginal atrophy. Options for topical estrogen treatment are increasing. Women’s healthcare professionals need to confirm appropriate use of estrogen and help patients identify which treatment option will work best for their situation and lifestyle.
KEY POINTS:
During perimenopause and menopause, estrogen levels decline in vaginal tissues
Referred to as vulvovaginal atrophy (VVA), this may result in discomfort or pain during intercourse or general dryness and discomfort
If patient complains of dyspareunia, and clinical examination is consistent with postmenopausal vaginal atrophy / atrophic vaginitis, local estrogen is the first line and most effective treatment
Estrogen treatment may not be appropriate or desired by all patients
Ascertain if estrogen is an appropriate option for the patient
Screen for a history of breast or uterine cancer
History of blood clots
Liver conditions
If patient is appropriate for treatment with local estrogen, offering the spectrum of choices can help a patient identify the product that will work best for them
While there is a theoretical concern regarding systemic estrogen absorption and risk for uterine cancer, based on evidence, professional organizations consider “the addition of progestin for endometrial protection is not needed” (ACOG)
Differentiating factors include
Creams
Can be used on the vulva as well as internally in the vagina
Tablets or caplets
Some can be used during the day
Some tablets may need to be used at night because of the way they dissolve
Applicators
May be an issue of patient preference and warrants discussion
Ring
Benefits include ease of use
For some women, there may be structural issues related to comfort and/or retention (e.g., short or narrow vagina / prolapse)
Make patients aware that there are non-estrogen options available for use by women who are not appropriate candidates for local estrogen including
Prasterone | Ospemifene
Laser Treatments have been advocated as a possible treatment, however VVA not a currently FDA-approved indication
More Follow-Up Data from the Estrogen vs Lubricant RCT
BACKGROUND AND PURPOSE:
RCTs have shown that vaginal estrogen creams and tablets, prasterone and ospemifene will provide relief from postmenopausal vaginal atrophy symptoms, but few studies have looked at sexual health and quality of life issues
Diem et al. (Menopause 2018) compared the efficacy of vaginal estradiol tablets and vaginal moisturizer to treat menopause-related quality of life and mood in women with vulvovaginal symptoms
METHODS:
Secondary data analysis of a 12-week, double-blind, placebo-controlled randomized trial (RCT)
Previous primary results on sexual function and decrease in severity of most bothersome symptoms were recently reported in JAMA Int Med (see summary below in ‘Related ObG Topics’)
Participants: Patients with moderate to severe symptoms of vulvovaginal itching, pain, dryness, irritation, or pain with penetration
Age 45 to 70 years, at least 2 years since last menses, report of at least 1 moderate to severe symptom at least weekly within the past 30 days or
Pain with penetration at least once monthly
Women were randomized to
10 µg estradiol tablet plus placebo gel
vaginal moisturizer plus placebo tablet
dual placebo
Tablets were daily for 2 weeks then twice weekly for remaining 10 weeks
Vaginal gel was used every 3 days for 12 weeks
The Menopause-Specific Quality of Life (MENQOL) questionnaire was used to assess changes in quality of life
Evaluated specifically
Depressive symptoms as measured by Patient Health Questionnaire 8
Anxiety symptoms as measure by the Generalized Anxiety Disorder (GAD-7)
RESULTS:
Vaginal estradiol resulted in a greater improvement in total MENQOL scores, compared to dual placebo
Mean difference between arms -0.3 at 12 weeks; 95% CI, -0.5, 0.0; P = 0.01
A favorable group mean difference was observed for vaginal estradiol for MENQOL sexual function domain
-0.4 at 12 weeks; 95% CI -1.0, 0.1; P = 0.005
A favorable group mean difference for vaginal estrogen was not observed in any of the other domains
Treatment with vaginal moisturizer did not provide greater improvement compared to placebo in total MENQOL scores or any MENQOL domains
Mean difference 0.2 at 12 weeks; 95% CI -0.1, 0.4; P = 0.38
Neither treatment group showed improvement compared with placebo in the Patient Health Questionnaire 8 or Generalized Anxiety Disorder Questionnaire
CONCLUSION:
Treatment with low-dose vaginal estradiol modestly improved menopause-related quality of life and sexual function domain scores in postmenopausal women with moderate-severe vulvovaginal symptoms
Effect on MENQOL score was similar to low-dose oral 17-beta estradiol 0.5mg/day noted in a previous study
The previous paper that reported on this study did not find a significant difference in sexual function using Female Sexual Function Index (FSFI) as the primary measuring tool
FSFI is much more detailed, while MENQOL asks three questions but focuses on whether a woman is bothered by a decrease in sexual deire, vaginal dryness during intercourse and avoiding intimacy
The authors conclude that “multiple approaches to measuring sexual QOL are needed”
