Menopausal Health Diagnosis and Treatment of the Non–Sex-related Symptoms of Vulvovaginal Atrophy Mary Jane Minkin, MD; Marsha K. Guess, MD Vulvovaginal atrophy is a common, chronic disorder that affects many postmenopausal women. Bothersome symptoms, including dryness, itching, irritation, incontinence, and recurrent UTIs, can be safely and effectively managed with the use of local vaginal estrogen therapy. D eclining estrogen levels at menopause may result in symptomatic vulvovaginal atrophy. Up to 45% of postmenopausal women may be affected, but only about one-fourth of symptomatic women seek medical help.1,2 Many women are too embarrassed to report their vulvovaginal symptoms and are unaware that effective, well-tolerated treatments for menopause-related vulvovaginal discomfort are available.1 The term vulvovaginal atrophy, by definition, encompasses the entire vulvar Follow OBG Management on and region, while the term vaginal atrophy is more specific. Both are used frequently in the literature, as are the closely related terms urogenital atrophy and genitourinary atrophy. While all of these terms may be used, this article will refer to the condition discussed herein as vulvovaginal atrophy and aims to review the nonsexual, “bothersome” signs and sympDr Minkin is Clinical Professor in the Department of Obstetrics, Gynecology and Reproductive Sciences and Dr Guess is Assistant Professor in the Section of Urogynecology and Reconstructive Pelvic Surgery at Yale University School of Medicine, New Haven, CT.

Signs and Symptoms of Vulvovaginal Atrophy Genital Signs and Symptoms The diagnosis of vulvovaginal atrophy is typically based on patient-reported symptoms and the results of a physical exam (Tables 1 and 2).3, 4 Vaginal pH and vaginal maturation index may aid in confirming the diagnosis. A vaginal pH test, administered by placing pH paper against the inside wall of the vagina, would reveal a pH of 4.6 or above (nor- Vulvovaginal and Urinary Symptoms of Vulvovaginal Atrophy Table 1.

A normal, premenopausal smear contains at least 15% superficial cells, while a postmenopausal smear from a patient with vulvovaginal atrophy typically contains fewer than 5% superficial cells.3 Urinary Signs and Symptoms As estrogen receptors are also present in the lower urinary tract, urinary symptoms, including symptoms suggestive of overactive bladder (eg, urgency, frequency, and nocturia), are frequently associated with vulvovaginal atrophy (see Table 1). Diminished estrogen causes the urethral mucosa and trigone of the bladder to thin and the supporting tissues and ligaments to weaken.5 A urethral caruncle, a benign, fleshy outgrowth at the urethral meatus, may be evident upon examination.3 Inflammation of the urethral and vulvar tissues may result in dysuria, and urinary incontinence may exacerbate irritation. Additionally, estrogen deprivation and increased vaginal pH may promote recurrent urinary tract infections (UTIs).6 Prior to menopause, estrogen Signs of Vulvovaginal Atrophy General External Internal Pale, dry, shiny appearance Thinning of the vulvar skin Thinning of vaginal epithelium Petechiae Loss of fat pads of mons pubis and labia majora Narrowing and shortening of the vagina Ulcerations Diminished elasticity and turgor of tissue Friability of tissue Receded labia minora, possibly with fusion Receded prepuce Urethral caruncle Diminished rugae Reduced secretions Erythema indicative of inflammation (ie, atrophic vaginitis) Sparse pubic hair Data from Mac Bride3 and the North American Menopause Society.4 34 The Female Patient | Vol 37 november/december 2012 All articles are available online at www.femalepatient.com Minkin and Guess stimulates vaginal epithelial cells to produce large amounts of glycogen. The epithelium is thick and sheds regularly into the vaginal lumen, where the glycogen is released, hydrolyzed to glucose, and metabolized to lactic acid by native lactobacilli. At menopause, decreased estrogen levels reduce the activity of this pathway. Less lactic acid leads to increased pH, loss of lactobacilli, and overgrowth of other species, which may predispose a patient to symptomatic vaginal infections or recurrent UTIs.3 Differential Diagnosis Alternative diagnoses of vulvovaginal atrophy may include infections (eg, Candida vulvovaginitis, bacterial vaginosis, and trichomoniasis), vulvovaginal dermatoses (eg, lichen sclerosis, lichen planus, and lichen simplex chronicus), contact irritation or allergy, cancerous or precancerous lesions, and desquamative inflammatory vaginitis.3, 7 Current Recommendations for the Treatment of Vulvovaginal Atrophy For initial treatment of vulvovaginal atrophy symptoms, the North American Menopause Society (NAMS) recommends nonhormonal vaginal lubricants and moisturizers, as well as continued intercourse to help promote blood flow to the area.4 One commonly used moisturizer, Replens (Lil’ Drug Store Products, Inc, Cedar Rapids, IA), has been shown to decrease or eliminate itching and irritation when applied three times per week.8 NAMS has not issued a statement on the use of alternative therapies, such as phytoestrogens and vitamins. While these nonprescription treatments can provide some relief of symptoms, they do not affect postmenopausal estrogen levels, which are the underlying cause of vulvovaginal atrophy. If nonhormonal interventions have been ineffective or when symptoms of atrophy are severe, NAMS suggests that estrogen be considered as a first-line therapy.4, 9 The American College of Obstetricians and Gynecologists and the Society of Obste- tricians and Gynaecologists of Canada concur with this recommendation. Systemic estrogen is also considered effective for the treatment of dryness, itching, and irritation associated with vulvovaginal atrophy, although it is not FoCUSPOINT If nonhormonal interventions have been ineffective or when symptoms of atrophy are severe, NAMS suggests that estrogen be considered as a first-line therapy. recommended unless the patient is significantly affected by other menopausal symptoms, such as hot flashes and night sweats.9 Over 25% of patients taking systemic estrogen may still experience bothersome vulvovaginal symptoms,10 which may be improved by local vaginal estrogen. Systemic estrogen has no proven benefit for UTI,6 incontinence,11 or overactive bladder symptoms.12 Local Vaginal Estrogen Treatment Options for Local Vaginal Estrogen All available local vaginal estrogen products approved for use in the United States (Estrace, Estring, Premarin, Vagifem; see Table 313-16) are considered effective and well tolerated at their recommended dosage.4 However, patients may wish to consider several factors in choosing a particular formulation, including ease, frequency, and form of administration. The applicators for the creams and the vaginal tablet are narrow enough for most patients. Some studies have used external application of the cream when insertion of the applicator was not possible, although this is not an indicated method of administration. Frequency of administration and The Female Patient | Vol 37 november/december 2012 37 Non-Sex-related Symptoms of Vulvovaginal Atrophy dosage of the creams vary according to the prescribed regimen. The tablet is administered every day for the first 2 weeks and then biweekly thereafter. The ring requires a certain amount of dexterity for insertion but only needs to be replaced every 90 days. If a woman cannot self-insert the ring, she can see her caregiver every 3 months for a replacement, enabling her to receive ongoing local therapy. Finally, if total dosage is a concern, the ultra-low-dose tablet (10 µg estradiol), which replaced the 25-µg formulation, provides the smallest amount of estradiol absorption.17 Anticipated Benefits of Local Vaginal Estrogen Local vaginal estrogen improves patient-reported symptoms of dryness and itchiness and returns the tissues to a healthier state with less paleness and dryness noted on clinical examination. It also restores vaginal pH to premenopausal levels, improves the vaginal maturation index, increases vaginal blood flow, and enhances fluid secretions.4 The effects of estrogen on connective tissue and smooth muscle are not read- Table 3. ily measured, but clinical examination may be used to verify the restoration of normal vaginal elasticity. Urinary symptoms may also improve with local vaginal estrogen administration.12 Vaginal estrogen has been shown to cure or improve urinary incontinence11, 12 and reduce the incidence of UTIs.6 Vaginal estrogen has also been used to treat dysuria resulting from urethral caruncles in postmenopausal women, although no randomized controlled studies to investigate this practice have been conducted. Following and Managing Women on Local Vaginal Estrogen Vulvovaginal atrophy is a chronic condition, and treatment usually must be continued to prevent the return of symptoms, although some women can eventually use less medication. Patients generally see results within 4 to 8 weeks; however, those with severe atrophy may need additional time. The typical follow-up period is 2 to 3 months. Safety data have been gathered up to 1 year, and longer-term data are not currently available.4 We suggest individualized Local Estrogen Therapies for Vulvovaginal Atrophy Product Type of Estrogen Recommended Dosing Regimen Premarin® vaginal cream Conjugated estrogens (625 μg per g cream) 0.5 g cream twice weekly or 0.5–2 g cream daily (21 days on, 7 days off) Estrace® vaginal cream Estradiol (100 μg per g cream) Initial: 2–4 g cream daily (1 or 2 weeks), reduced gradually to half initial dosage (1 or 2 weeks) Maintenance: 1 g, one to three times per week Estring® vaginal ring Estradiol (7.5 μg released per 24 h) 1 ring replaced every 90 days Vagifem® vaginal tablet Estradiol (10 μg per tablet) Initial: 1 vaginal tablet daily (2 weeks) Maintenance: 1 vaginal tablet twice weekly Data from product package inserts.13-16 38 The Female Patient | Vol 37 november/december 2012 Minkin and Guess therapy tailored to the patient’s wants and needs. Local Vaginal Estrogen Use in Breast Cancer Patients Vaginal estrogen therapy may be used with caution in breast cancer patients, in consultation with the patient’s oncologist and according to patient preference.18 Oncologists are often comfortable with therapeutics that provide a very low, predictable release of estrogen, although no general recommendations can be made in the absence of large, randomized controlled trials. Discussing the Risks and Benefits of Local Vaginal Estrogen Use with Your Patients To provide the patient with a balanced view of the risks and benefits of local vaginal estrogen, the clinician should discuss data pertaining to safety and effectiveness. Many studies performed over the past two decades show that various formulations provide effective relief of vulvovaginal dryness and itching, although the use of moderate to high doses of the conjugated estrogens cream has been associated with endometrial overstimulation, uterine bleeding, breast pain, and perineal pain.19 A low-dose regimen of the conjugated estrogens cream has a better safety profile and, like the tablet and ring, does not require coadministration of progestin.20 Additionally, it may be useful to explain that steady-state plasma estradiol levels on the ultra-low-dose tablet are similar to baseline levels.17 For most women presenting with moderate to severe vulvovaginal atrophy, the potential benefits of low-dose, local vaginal estrogen therapy are significant while the risks appear to be minimal. Increasing Awareness of Vulvovaginal Atrophy: Role of the Clinician A recent international study found that American women are particularly vulnerable to embarrassment in discussing their vulvovaginal discomfort, compared to women in other developed nations.1 Thirty-three percent of surveyed American women aged 55 to 65 years who experienced vaginal discomfort had not discussed the issue with anyone. Of these women, 60% said that talking about their vaginal discomfort made them feel uncomfortable or embarrassed, 52% considered it a private matter, 49% considered it to be a normal part of aging, and 20% preferred if someone else (such as a provider) initiated the conversation. Only 26% of American women who experienced vaginal discomfort as a result of menopause were prescribed treatment. Of this pop- FoCUSPOINT Thirty-three percent of surveyed American women aged 55 to 65 years who experienced vaginal discomfort had not discussed the issue with anyone. ulation, 32% had waited a year or more before seeking treatment, and 11% had waited 3 or more years. All clinicians who routinely care for postmenopausal women should be aware of these communication issues and proactively encourage women to report any present or future vulvovaginal discomfort. The clinician, frequently the ObGyn, plays a key role in identifying those patients with vulvovaginal atrophy who might benefit from treatment and may consider the following: 1.Adding questions about vulvovaginal and urinary symptoms to intake paperwork 2.Direct questioning 3.Reflex questioning based on findings of the physical exam. If using direct or reflex questioning, it The Female Patient | Vol 37 november/december 2012 39 Non-Sex-related Symptoms of Vulvovaginal Atrophy may be useful to ask patients specifically about both vaginal and urinary symptoms, perhaps prefacing these questions with a general statement such as, “Many women experience vaginal dryness or itching, pain with sex or urination, or incontinence around and after menopause.” Routine gynecologic exams help to diagnose patients experiencing these symptoms and provide a venue for encouraging patients to seek treatment, if appropriate. FoCUSPOINTØ Primary care physicians and urologists, in particular, are encouraged to ask women about discomfort in the lower urinary tract and genitalia. ever, that the International Classification of Diseases (ICD) 9 coding does not include this term. Clinicians must instead choose from the ICD-9 codes for “vulvar atrophy” (624.1) or for “postmenopausal atrophic vaginitis” (627.3). It is recommended that the latter code be applied when symptoms are more generalized, despite its false implication that an inflammatory process must be present. Summary Vulvovaginal atrophy is a common, chronic disorder that affects many postmenopausal women. Bothersome sequelae, including dryness, itching, irritation, and incontinence, and recurrent UTIs can be safely and effectively managed with the use of local vaginal estrogen therapy. However, a major challenge still exists in reaching the affected population. ObGyns, as well as primary care physicians and urologists, can help by identifying symptomatic women, addressing their concerns, and counseling them about available treatment options. Acknowledgments Primary care physicians and urologists, in particular, are encouraged to ask women about discomfort in the lower urinary tract and genitalia. If primary care physicians or urologists elicit a history of recurrent UTIs or other urinary complaints, such as urgency or frequency, a physical exam can be performed to evaluate for atrophy and, when indicated, therapy can be initiated. A consultation should be obtained from a urogynecologist, gynecologist, or urologist with an interest in atrophic symptoms if the provider is uncomfortable treating women with these symptoms, for women in whom estrogen is contraindicated or who are refractory to therapy.
