Abstract
The following Consensus Statement is endorsed by The International Menopause Society, The North American Menopause Society, The Endocrine Society, The European Menopause and Andropause Society, The Asia Pacific Menopause Federation, The International Osteoporosis Foundation and The Federation of Latin American Menopause Societies.
1. Introduction
The publication of the Global Consensus on Menopausal Hor-mone Therapy in 2013 by leading global menopause societies succeeded in presenting guidelines in a troubled therapeutic area that are helpful to both health-care providers and potential users of menopausal hormone therapy (MHT). The revised statement is aimed at updating and expanding the areas of consensus. The revised statement is presented in bullet-point format to facilitate ease of use. The revised statement contains only areas of consensus and does not replace the more detailed and fully referenced rec-ommendations of the individual societies (referenced at the end of the document). Hopefully, this statement will enable health-care providers to offer those women in midlife, who may benefit from MHT, the opportunity to make an informed decision.
2. Section A: benefit/risk profile of MHT
– MHT, including tibolone and the combination of conjugated equine estrogens and bazedoxifene (CE/BZA), is the most effec-tive treatment for vasomotor symptoms (VMS) associated with menopause at any age, but benefits are more likely to outweigh risks if initiated for symptomatic women before the age of 60 years or within 10 years after menopause.
– If MHT is contraindicated or not desired for treatment of VMS, selective serotonin reuptake inhibitors and serotonin-norepinephrine reuptake inhibitors such as paroxetine, escitalo-pram, venlafaxine and desvenlafaxine, which have been shown to be effective in randomized controlled trials (RCTs), may be considered. Gabapentin may also be considered.
– Quality of life, sexual function and other menopause-related com-plaints, such as joint and muscle pains, mood changes and sleep disturbances, may improve during MHT.
– MHT, including tibolone and CE/BZA, is effective in the prevention of bone loss in postmenopausal women.
– MHT has been shown to significantly lower the risk of hip, verte-bral and other osteoporosis-related fractures in postmenopausal women.
– MHT is the only therapy available with RCT-proven efficacy of fracture reduction in a group of postmenopausal women not selected for being at risk of fracture and with mean T-scores in the normal to osteopenic range.
– MHT, including tibolone, can be initiated in postmenopausal women at risk of fracture or osteoporosis before the age of 60 years or within 10 years after menopause.
– Initiation of MHT after the age of 60 years for the indication of fracture prevention is considered second-line therapy and requires individually calculated benefit/risk, compared to other approved drugs. If MHT is elected, the lowest effective dose should be used.
– MHT, including tibolone, is effective in the treatment of vulvo-vaginal atrophy (VVA), now also considered as a component of the genitourinary syndrome of menopause (GSM). Local low-dose estrogen therapy is preferred for women whose symptoms are limited to vaginal dryness or associated discomfort with inter-course or for the prevention of recurrent urinary tract infections. Ospemifene, an oral selective estrogen receptor modulator, is also licensed in some countries for the treatment of dyspareunia attributed to VVA.
– RCTs and observational data as well as meta-analyses provide evidence that standard-dose estrogen-alone MHT may decrease the risk of myocardial infarction and all-cause mortality when initiated in women younger than 60 years of age and/or within 10 years of menopause.
– Data on estrogen plus progestogen MHT initiated in women younger than age 60 years or within 10 years of menopause show a less compelling trend for mortality benefit, and evidence on car-dioprotection is less robust with inconsistent results compared to the estrogen-alone group.
– The risk of venous thromboembolism (VTE) and ischemic stroke increases with oral MHT, although the absolute risk of stroke with initiation of MHT before age 60 years is rare. Observational stud-ies and a meta-analysis point to a probable lower risk of VTE and possibly stroke with transdermal therapy (0.05 mg twice weekly or lower) compared to oral therapy.
– The risk of breast cancer in women over 50 years of age associ-ated with MHT is a complex issue with decreased risk reported from RCTs for estrogen alone (CE in the Women’s Health Ini-tiative (WHI)) in women with hysterectomy and a possible increased risk when combined with a progestin (medroxypro-gesterone acetate in the WHI) in women without hysterectomy. The increased risk of breast cancer thus seems to be primarily, but not exclusively, associated with the use of a progestin with estrogen therapy in women without hysterectomy and may be related to the duration of use.
– The risk of breast cancer attributable to MHT is rare. It equates to an incidence of <1.0 per 1000 women per year of use. This is similar or lower than the increased risk associated with common factors such as sedentary lifestyle, obesity and alcohol consump-tion. The risk may decrease after treatment is stopped, but data are inconsistent.
– Women experiencing a spontaneous or iatrogenic menopause before the age of 45 years and particularly before 40 years are at a higher risk for cardiovascular disease and osteoporosis and may be at increased risk of affective disorders and dementia. In such women, MHT reduces symptoms and preserves bone den-sity. Observational studies that suggest MHT is associated with reduced risk of heart disease, longer lifespan, and reduced risk of dementia require confirmation in RCTs. MHT is advised at least until the average age of menopause.
– MHT initiated in early menopause has no substantial effect on cognition, but, based on observational studies, it may prevent Alzheimer’s disease in later life. In RCTs, oral MHT initiated in women aged 65 or older also has no substantial effect on cogni-tion and increases the risk of dementia.
– MHT may be beneficial in improving mood in early post-menopausal women with depressive and/or anxiety symptoms. MHT may also be beneficial for perimenopausal women with major depression but antidepressant therapy remains first-line treatment in this setting.
3. Section B: general principles governing the use of MHT
– The option of MHT is an individual decision in terms of qual-ity of life and health priorities as well as personal risk factors such as age, time since menopause and the risk of VTE, stroke, ischemic heart disease and breast cancer. MHT should not be recommended without a clear indication for its use.
– Consideration of MHT for symptom relief or osteoporosis pre-vention should be a part of an overall strategy including lifestyle recommendations regarding diet, exercise, smoking cessation and safe levels of alcohol consumption for maintaining the health and quality of life of peri- and postmenopausal women.
– MHT includes a wide range of hormonal products and routes of administration, including tibolone (where available) or CE/BZA, with potentially different risks and benefits. However, evidence regarding differences in risks and benefits between different products is limited.
– The type and route of administration of MHT should be consistent with treatment goals, patient preference and safety issues and should be individualized. The dosage should be titrated to the lowest appropriate and most effective dose.
– Duration of treatment should be consistent with the treatment goals of the individual, and the benefit/risk profile needs to be individually reassessed annually. This is important in view of new data indicating longer duration of VMS in some women.
– Estrogen as a single systemic agent is appropriate in women after hysterectomy but concomitant progestogen is required in the presence of a uterus for endometrial protection with the excep-tion that CE can be combined with BZA for uterine protection.
– The use of continuous testosterone therapy, either alone or with MHT, is supported in carefully selected postmenopausal women with sexual interest/arousal disorder (in countries with regula-tory approval).
– The use of custom-compounded hormone therapy is not recom-mended because of lack of regulation, rigorous safety and efficacy testing, batch standardization, and purity measures.
– Current safety data do not support the use of systemic MHT in breast cancer survivors, although discussions, in selected women and in conjunction with each woman’s oncologist, may occur for compelling reasons after non-hormonal or complementary options have been unsuccessful.
