Genitourinary Syndrome of Menopause

Introduced in 2014, genitourinary syndrome of menopause (GSM) describes a variety of unpleasant genital, sexual and urinary symptoms that can either be isolated or coexisting and are not related to other medical conditions. GSM is a chronic and progressive condition that requires early recognition and appropriate management to preserve urogenital health. Despite the importance of early detection and treatment, the condition is consistently underdiagnosed and undertreated. Herein, we emphasize how to diagnose GSM in postmenopausal, hypoestrogenic, and hypoandrogenic women and summarize evidence-based treatments focusing on prescription treatments and adjunctive therapies.

Using menopausal hormone therapy after a cancer diagnosis in Ireland

BACKGROUND

Menopause may cause a constellation of symptoms that affect quality of life. Many women will have menopause induced or exacerbated by treatment for cancer whether that be through surgery, chemotherapy, radiotherapy, or anti-endocrine therapy. As treatments advance, the number of people living with and beyond a cancer diagnosis is set to increase over the coming years meaning more people will be dealing with the after effects of cancer and its treatment.

AIMS

This review aims to summarise available data to guide clinicians treating women with menopausal symptoms after the common cancer diagnoses encountered in Ireland. The use of menopausal hormone therapy is discussed as well as non-hormonal and non-pharmacological options.

CONCLUSIONS

Managing menopausal symptoms is an important consideration for all physicians involved in the care of people living with and beyond a cancer diagnosis. High-quality data may not be available to guide treatment decisions, and, thus, it is essential to take into account the impact of the symptoms on quality of life as well as the likelihood of recurrence in each individual case.

Hormone replacement therapy - Current recommendations

Menopause is a major life event that can affect women in several ways. Its onset marks the end of the reproductive life cycle, and its impact can be both short and long term. Menopause is often a gradual process, preceded by a transitional period known as perimenopause. The average age of menopause in the UK is 51. The clinical manifestations of menopause result from the eventual exhaustion of oocytes within the ovaries. This leads to a chronic hypo-estrogenic state, which in the short term causes menopausal symptoms and over a long term, has an impact on bone and cardiovascular health. There has been a steep drop in the prescription of hormone replacement therapy (HRT) following the publication of the Women's Health Initiative Study and the Million Women Study. It is currently estimated that approximately a million women in the UK are taking HRT for control of their menopausal symptoms. This review summarises the current recommendations for HRT use in menopausal women. The benefits of HRT in improving the symptoms of menopause are discussed as well as the potential role of HRT in managing long-term sequelae is covered. Evidence pertaining to the potential risks associated with HRT is also be reviewed.

Urogenital atrophy: The 'unknown factors' challenging current practice

Urogenital atrophy occurs as a result of the effect of estrogen deficiency on the tissue quality in the vulva, vagina, urethra and bladder. It is a common consequence of the menopause, with possibly up to 80% of women experiencing symptoms. Despite a number of different diagnostic methods, there is no validated objective method by which to confirm the diagnosis in clinical practice and research settings. Education, for women and clinicians, is called for to support diagnosis and treatment. However, before this can be of global benefit, development of an accessible and reproducible diagnostic test is required. Current assessment methods include routine history and clinical examination, with the clinician's opinion based on their subjective observations. A vaginal smear to assess the ratio of superficial to parabasal cells and measurement of the pH of the vaginal secretions is more commonly used in research settings. A number of formulae have been postulated to facilitate the diagnosis including the Vaginal Health Index, the Vulval Health Index, the Genitourinary Syndrome of the Menopause assessment tool, the Genital Health Clinical Evaluation and vaginal biopsy and assessment of the vaginal microbiome. However, none of these potential methods of assessment has been validated. This article focuses on what we do not know about urogenital atrophy including the prevalence, the most appropriate terminology, aetiology, pathogenesis and the most objective and reproducible method of assessment.

A Pilot Randomized, Double-blind, Placebo-controlled Clinical Trial on the Efficacy and Safety of a Transdermal Gel that Delivers CO2 in the Treatment of Vulvovaginal Atrophy

This prospective study aimed to assess the efficacy of a transdermal CO2 gel in promoting regeneration in the vulvovaginal area in postmenopausal women experiencing symptoms as part of genitourinary syndrome of menopause (GSM). Transdermal carboxytherapy refers to the application of CO2 through the skin's superficial layer, which is intended to increase oxygenation (through the Bohr effect) and angiogenesis, thus helping to reduce symptoms of GSM. In this study, 20 women with moderate or severe signs or symptoms of vulvovaginal atrophy were randomized to receive either transdermal CO2 therapy (n=10) or a placebo gel (ultrasound gel, n=10). The gels (transdermal CO2 gel or the placebo) were applied by the patients at home. The gels were applied in two treatment cycles (10 days of total treatment). Each cycle involved daily applications of the gel to the vulvovaginal area, from Monday to Friday, with no application on weekends. The Female Sexual Function Index (FSFI) and Day-to-Day Impact of Vaginal Aging (DIVA) questionnaires were used to gather standardized information, and biopsy samples were obtained from the vagina and vulva for histological analysis, both on the first day of treatment and 10 days after the final application of gel. Patients who received the transdermal CO2 gel showed significant improvements on the FSFI and DIVA questionnaires and the biopsies revealed that the CO2 gel had a regenerative effect on vulvovaginal tissues.

Impact of postmenopausal vaginal discomfort on sex and relationships in Brazil: the CLOSER survey

OBJECTIVE

The CLOSER (CLarifying Vaginal Atrophy's Impact On SEx and Relationships) survey investigated how postmenopausal vaginal atrophy (VA) affects relationships between Brazilian women and male partners.

METHODS

Postmenopausal women (age 55-65 years) with VA, and male partners of women with the condition, completed an online survey on the impact of VA and local estrogen treatment on intimacy and relationships.

RESULTS

A total of 360 women and 352 men from Brazil were included. Women (83%) and men (91%) reported that they were comfortable discussing VA with their partners. Women's key source of information on VA was health-care providers (HCPs), but 44% felt that not enough information is available. VA caused 70% of women to avoid sexual intimacy and resulted in less satisfying sex. VA had a negative impact on women's feelings and self-esteem. Women (76%) and men (70%) both reported that treatment with vaginal estrogen improved their sexual relationship, primarily by alleviating women's pain during sex. Women (56%) and men (59%) felt closer to each other after treatment.

CONCLUSIONS

VA had a negative impact on sexual relationships for both women and men in Brazil, and reduced women's self-confidence. Vaginal hormone therapy improved couples' sexual relationships. A proactive attitude of HCPs is essential to educate women on VA and the potential benefits of treatment.

Modern management of genitourinary syndrome of menopause

The genitourinary syndrome of menopause (GSM) is the accepted term used to describe the broad spectrum of genitourinary tract symptoms and signs caused by the loss of endogenous sex steroids that occurs at the time of and after the menopause. Global improvements in healthcare have resulted in an ageing population. Today, women are spending 40% of their lives in the postmenopausal state, and with 50–70% of postmenopausal women reporting symptomatic GSM, safe and efficacious treatments are needed for this troublesome condition. This article reviews current evidence for non-pharmacological and pharmacological treatments with a focus on novel and minimally invasive procedures such as energy-based devices (CO₂ laser, YAG laser), hyaluronic acid, dehydroepiandrosterone, and selective oestrogen receptor modulators.

Implications of the Pharmacovigilance Risk Assessment Committee recommendations for the treatment of genitourinary syndrome

The European Medicines Agency's Pharmacovigilance Risk Assessment Committee has issued statements regarding limiting the use of high-dose oestradiol creams by women experiencing the genitourinary syndrome of menopause, and such statements carry much medicolegal weight. Although a low dose is most often used, some clinicians opt to use higher dose creams with close monitoring of the patient. The committee should publish the evidence behind these statements or amend its official position.

Does age at the start of treatment for vaginal atrophy predict response to vaginal estrogen therapy? Post hoc analysis of data from a randomized clinical trial involving 205 women treated with 10 μg estradiol vaginal tablets

OBJECTIVE

Local estrogen therapy (ET) can improve vaginal atrophy symptoms and associated cellular changes in postmenopausal women. This study evaluated whether age at the start of treatment influences response.

METHODS

This post hoc analysis used data from a double-blind, randomized, placebo-controlled trial (NCT00108849), which treated 205 postmenopausal women aged ≥45 years with 10 μg vaginal ET for 52 weeks.Women aged <60 or ≥60 years at treatment start were evaluated according to the following: vaginal maturation index (assessed by vaginal cytology samples), vaginal pH, and most bothersome symptom (both graded on four-point scales). Covariance analysis aimed to evaluate mean change differences between groups from baseline-week 52.

RESULTS

Vaginal ET improved vaginal maturation index (for all cell layers), vaginal pH, and symptom scores for both age groups. However, cytological profiles were significantly different in the <60 (n = 143) versus ≥60 years group (n = 55, estimated effect: -3.7, P  = 0.0003 [parabasal cells]; 5.8, P  = 0.0002 [intermediate cells]), indicating reduced cellular responsiveness to treatment among older women. Treatment effect on vaginal pH was less for older women, with a between-group difference of -0.19 (standard error = 0.05; P  = 0.0003).

CONCLUSIONS

Findings suggest that treatment may be initiated at any age since low-dose vaginal ET improved symptoms and signs of vaginal atrophy in both younger (<60 years) and older (≥60 y) women. The stronger response observed in younger women supports current clinical recommendations to start treatment early. Continued treatment may be important to avoid recurrence of vaginal atrophy.

Genitourinary syndrome of menopause

Genitourinary syndrome of menopause affects approximately 50% of women post-menopause and is under-reported. This review of the condition including established and newer treatment options aspires to empower clinicians to ask about symptoms and be more proactive in their management.
