Limpaphayom, Dr. Sukanya Chaikittisilpa Vietnam: Dr Mai Thi Cong Danh Background The Asia-Pacific region contains more than 50% of the world’s population and is made up of ethnically diverse populations representing a wide range of socioeconomic and educational circumstances. Within this region there are large differences in accessibility to information about the menopause, to health care services and to health care professionals with an interest in menopause The availability of some investigations generally considered desirable for menopausal women e.g. mammogram and bone mineral density, is limited in many regions Decision-making regarding the menopause Each woman should be given the opportunity to participate in the decision-making process with respect to menopause management including hormone replacement therapy (HRT). Prior to the start of HRT, a woman’s health care provider should inform her about the risks and benefits of therapy, its potential general side effects, and side-effects that may specifically apply to her situation. This should be repeated at each of her periodically scheduled follow-up visits during therapy. Use of HRT should be individualized. Treatment goals should take into account symptoms that may impact quality of life e.g. decreased sexual function and insomnia. When counselling patients, risks should be conveyed in absolute numbers rather than percentages to avoid unnecessary alarm. Adapted from Asian Guidelines 2006 Recommendations: Healthy Lifestyle Any physical activity is better than being sedentary. Regular exercise reduces total and cardiovascular mortality. Better metabolic profile, balance, muscle strength, cognition and quality of life are observed in physically active persons. Heart events, stroke, fractures and breast cancer are significantly less frequent. Benefits far overweigh possible adverse consequences: the more, the better, but too much may cause harm. Injury to the musculo-articulo-skeletal system should be avoided. Optimal exercise prescription is at least 30 minutes of moderate-intensity exercise, at least three times weekly. Two additional weekly sessions of resistance exercise may provide further benefit. IMS Recommendations 2007 Obesity (body mass index >30 kg/m2) affects significant segments of the population and is becoming an increasing problem in postmenopausal women. Weight loss of only 5–10% is sufficient to improve many of the abnormalities associated with the insulin resistance syndrome associated with obesity. The basic components of a healthy diet are: four to five servings/day of fruits and vegetables, whole grain fibres, fish twice a week, and low total fat. Consumption of salt should be limited and the daily amount of alcohol should not exceed 20 g for women. Smoking and tobacco chewing should be strongly discouraged. Lifestyle modifications include socializing, and being physically and mentally active. Adapted from IMS Updated Recommendations 2007 Indications for Hormone Replacement Therapy (HRT) HRT is recommended as the primary and most important option to alleviate menopausal symptoms (vasomotor symptoms, sleep disturbances associated with vasomotor symptoms, and urogenital complaints). When hormones are considered solely for the treatment of vulvovaginal symptoms, primary consideration should be given to the use of topical vaginal products. HRT remains an option for the prevention of osteoporosis. When prescribing solely for the prevention of osteoporosis, HRT should be considered along with non-oestrogen medications for women at significant risk of osteoporosis. By decreasing menopausal symptoms, HRT may improve the overall healthrelated quality of life. IMS Recommendations 2007 HRT Dosage recommendation The lowest effective dose consistent with treatment goals should be used. Lower doses than the presently used standard doses should be considered, such as daily oral doses of 0.3 mg conjugated estrogens or 0.25- 0.5 mg micronized 17ß-estradiol, tibolone 1.25 mg, transdermal 0.025 mg 17ßestradiol, or the equivalent. Doses higher than those conventionally used for menopause management should be considered for women with premature menopause Duration of therapy From available evidence, there is no reason to place mandatory limits on the duration of treatment. HRT should be given for as long as the benefits outweigh the risks. Risks/benefits should be periodically assessed. The greatest benefits of HRT occur when it is initiated during the menopausal transition or in the early menopause. Rationale for adjunctive progestogen In women with a uterus, oestrogen therapy causes a dose- and durationdependent increase in the risk of endometrial cancer. The primary menopause-related indication for progestogen therapy is endometrial protection from unopposed oestrogen. Ordinarily, postmenopausal women without a uterus should not be prescribed progestogen. Oestrogen therapy should usually be given continuously, e.g. without a drugfree interval. Adjunctive progestogen may be given continuously or cyclically, e.g. for 12 days each month. Long-cycle adjunctive progestogen therapy, such as continuous oestrogen with adjunctive progestogen every 3–6 months for 12–14 days, is not recommended because the safety of long-cycle regimens has not been sufficiently documented. There are insufficient safety data to support the use of a progestin-containing intrauterine device or the safety of ultra-low doses of oestrogen therapy without adjunctive progestogen. IMS recommendations 2007 Vaginal Oestrogen Therapy Oestrogen therapy improves urogenital changes of the menopause. When prescribing solely for atrophic symptoms, local low dose vaginal products are the treatment of choice. Most vaginal oestrogens produce minimal rises in serum oestradiol and the potential for endometrial proliferation with long-term use seems very low Current data are insufficient to make a recommendation regarding endometrial protection for durations of use of oestrogens greater than 1 year. Adapted from Suckling J et al Cochrane Review 2003 Androgen Therapy Menopausal women (especially after bilateral oophorectomy) complaining of distressing low sexual desire (hypoactive sexual desire disorder) and/or unexplained tiredness persisting after adequate oestrogenization may be counselled about the possibility of testosterone supplementation The long-term safety of androgen treatment has not been adequately studied It is noted that at present few if any testosterone preparations suitable for treatment of postmenopausal women are available in the Asia-Pacific region Alternatives to hormone therapy Women who wish to avoid HRT, or in whom HRT is contraindicated, may choose therapies other than hormonal preparations to relieve their menopausal symptoms. These include SSRIs, SNRIs, clonidine, gabapentin, complementary and alternative medicines The degree of symptom relief is lower than that attained with HRT and there may be side-effects. Long-term safety and efficacy data are lacking. Women choosing to use complementary and alternative medicines to relieve menopausal symptoms should be made aware that the efficacy is less than that of HRT and quality control is questionable. Premature menopause (under age 40 years) Women with premature menopause have special needs and may require additional counselling Whenever possible, the ovaries should be conserved in premenopausal women having hysterectomy for benign disease Doses higher than those conventionally used for menopause management should be considered for women with premature menopause HRT is recommended at least until the age of normal spontaneous menopause, after which the woman should be managed according to normal guidelines for a postmenopausal woman After surgical menopause, oestrogen as well as androgen therapy can be considered Recommended Initial Assessment for peri- or postmenopausal women The Consensus group emphasized the need to educate all healthcare professionals and postmenopausal women regarding the management of the menopause including HRT. Initial assessment by any practicing healthcare professional should include: History: symptoms general medical history gynaecological history family history (especially malignancy) sexual history risk factors for menopause related diseases such as osteoporosis Examination: general, including weight, height, blood pressure breast, pelvic examinations Investigations: Advised only Pap or cervical smear, Complete blood count, Fasting blood sugar, Fasting Lipid profile Other investigations: to be ordered on a case to case basis could include: Liver function tests, thyroid function tests, mammography, bone mineral density, pelvic ultrasonography Recommended Management at Follow-Up History: including response to treatment, side-effects and related problems Examination: Blood pressure, weight, height, breast and pelvic examination Investigations: Fasting lipid profile, Fasting blood glucose, pap or cervical smear (as per local guidelines) Other investigations: to be ordered on a case-to-case basis could include liver function tests, thyroid function tests, mammography, bone mineral density, pelvic ultrasonography Frequency of Follow-Up In rural areas in many Asia-Pacific countries, there is a lack of state-of-the art medical facilities and instrumentation, such as equipment for mammography and bone mineral density. Therefore, while encouraging medical surveillance to the fullest extent possible, the Consensus Group considered it inappropriate to provide generally applicable guidance on frequency of medical assessments prior to and during HRT. Whenever possible, at least annual re-assessment is advised. Menopause specific issues: Osteoporosis HRT is effective in preventing the bone loss associated with the menopause and decreases the incidence of all osteoporosis related fractures, including vertebral and hip fractures, even in patients at low risk for fractures. HRT is indicated for the prevention of bone loss in women with premature menopause and secondary amenorrhoea. HRT is indicated in postmenopausal women in the age group 50–60 years presenting with a risk for fracture. Potential adverse effects of HRT can be limited by using lower than standard doses or by avoiding oral administration, without compromising the beneficial effect of HRT on bone. The protective effect of HRT on bone mineral density is lost after cessation of therapy at an unpredictable rate. Although some degree of fracture protection may remain after cessation of HRT, the patient at risk for fracture should receive additional therapy with proven bone sparing medication. The continuation of HRT after the age of 60 for the sole purpose of the prevention of fractures should take into account the possible side effects in the individual of the specific dose and method of administration of HRT, compared to other proven therapies. The initiation of HRT for the sole purpose of the prevention of fractures is not recommended after the age of 60 years. IMS recommendations Climacteric 2007 HRT may be recommended as a first-line therapy in postmenopausal women below the age of 60 at risk of osteoporosis-related fractures, in the absence of data for the efficacy and safety of alternative preparations Breast cancer Oestrogen/progestogen therapy for up to 5 years does not add significantly to lifetime risk of breast cancer. Beyond that time, the increase in risk is small, and comparable to other risks such as being obese or drinking more than 2 standard drinks of alcohol per day Oestrogen-only therapy for up to 7 years does not significantly increase breast cancer risk. Young postmenopausal women starting on combined HRT for the first time should be advised that breast cancer risks do not appear to increase in the first 7 years of use. Hysterectomized women on unopposed oestrogen are not at increased risk of breast cancer and some may even have a small reduction in risk. Cardiovascular disease Current evidence supports the cardioprotective effects of HRT when initiated within 5 years of menopause or under age 60. Young healthy postmenopausal women can therefore be started on HRT when clinically warranted without fear of increased cardiovascular disease risk. HRT is not recommended exclusively for primary or secondary prevention of cardiovascular disease. Oral HRT should not be prescribed to women with a previous episode of venous thromboembolism. Women seeking HRT who have potential or confirmed risk factors for venous thromboembolism and stroke need individualized counselling; in these situations, transdermal HRT might be preferable to oral formulations. Colon cancer Evidence supports the fact that combined HRT reduces colorectal cancer risk. However, HRT is not recommended exclusively for prevention of colon cancer. Cognitive impairment and dementia Evidence supports the fact that oestrogen therapy may reduce the risk of Alzheimer’s dementia when initiated near to the time of menopause HRT should not be used exclusively for prevention or treatment of cognitive impairment, Alzheimer’s disease or other forms of dementia. Adapted from IMS Recommendations Menopause in the Asia Pacific region: special considerations Experience of the menopause There is considerable diversity regarding culture, customs and religious practices within the Asia-Pacific region. As a result, the management of the menopause may differ across countries in the Asia-Pacific region and across different areas within a given country or region. In any given country or region, major differences in the experience and the response to the menopause may be found in rural/urban regions, at different educational levels and in different lifestyles. Individualizing menopause management is therefore of special importance. Adapted from Asian Guidelines Climacteric 2006 Menopausal symptoms The prevalence of menopausal symptoms varies within the Asia-Pacific region and is different from that usually reported in predominantly caucasian populations. Whilst vasomotor symptoms are less frequent and intense in the Asia-Pacific region, somatic symptoms (e.g. muscle and joint pain, dizziness, irritability and insomnia) appear to be more common than in predominantly caucasian populations. Cardiovascular disease The prevalence of obesity, diabetes mellitus and hypertension is rapidly increasing in the Asia-Pacific region with a consequent increase in cardiovascular risk. This is a matter of great public health concern. Dietary and lifestyle modification should be promoted as first-line prevention and treatment. The use of HRT may have a beneficial impact on these factors but its role remains to be determined. Use of HRT Low dose HRT is especially appropriate for women in the Asia-Pacific region who in general have a low incidence and severity of vasomotor symptoms Some somatic symptoms commonly experienced by postmenopausal women in the Asia-Pacific region respond to treatment with low dose HRT Resources Resources used in the preparation of this statement include: Guidelines for hormone replacement therapy of Asian women during the menopausal transition and thereafter.
