Abstract: OBJECTIVE:: To update for both clinicians and the lay public the evidence-based position statement published by The North American Menopause Society (NAMS) in March 2007 regarding its recommendations for menopausal hormone therapy (HT) for postmenopausal women, with consideration for the therapeutic benefit-risk ratio at various times through menopause and beyond. DESIGN:: An Advisory Panel of clinicians and researchers expert in the field of women's health was enlisted to review the March 2007 NAMS position statement, evaluate new evidence through an evidence-based analysis, and reach consensus on recommendations. The Panel's recommendations were reviewed and approved by the NAMS Board of Trustees as an official NAMS position statement. The document was provided to other interested organizations to seek their endorsement. RESULTS:: Current evidence supports a consensus regarding the role of HT in postmenopausal women, when potential therapeutic benefits and risks around the time of menopause are considered. This paper lists all these areas along with explanatory comments. Conclusions that vary from the 2007 position statement are highlighted. Addenda include a discussion of risk concepts, a new component not included in the 2007 paper, and a recommended list of areas for future HT research. A suggested reading list of key references is also provided. CONCLUSIONS:: Recent data support the initiation of HT around the time of menopause to treat menopause-related symptoms; to treat or reduce the risk of certain disorders, such as osteoporosis or fractures in select postmenopausal women; or both. The benefit-risk ratio for menopausal HT is favorable close to menopause but decreases with aging and with time since menopause in previously untreated women.

Abstract: OBJECTIVE: To determine the effects of lower doses of conjugated estrogens (CE) alone or in combination with medroxyprogesterone acetate (MPA) on body weight and to evaluate the influence of body mass index (BMI) on the effect of lower-dose CE or CE/MPA on vasomotor symptoms, vaginal atrophy, bone mineral density (BMD), endometrial safety, and side effects such as endometrial bleeding and breast pain. DESIGN: In this large clinical trial [the Women's Health, Osteoporosis, Progestin, Estrogen (Women's HOPE) study], 2,673 healthy, postmenopausal women with intact uteri were randomized for 1 year of CE 0.625, CE 0.625/MPA 2.5, CE 0.45, CE 0.45/MPA 2.5, CE 0.45/MPA 1.5, CE 0.3, CE 0.3/MPA 1.5 (all doses mg/d), or placebo. Weight, BMI, number and severity of hot flushes, vaginal atrophy (as determined by the vaginal maturation index), bleeding profiles, breast pain, and endometrial biopsies were evaluated. A subset of 822 women was randomized into a 2-year substudy to evaluate changes in BMD with lower-dose CE or CE/MPA regimens. RESULTS: After 1 year of treatment, a small but significant (P < 0.05) gain in body weight from baseline was observed in all arms of the study, the largest increase in body weight occurring in the placebo group [1.15 +/- 0.21 (SE) kg]. Body mass index had no significant effect on changes from baseline for vasomotor symptoms, bleeding patterns, vaginal atrophy, BMD, endometrial safety, or breast pain when analyzed both by analysis of covariance with baseline BMI as covariate or when participants were grouped into BMI less than 25 kg/m and BMI of 25 kg/m or greater. In placebo-treated women, vaginal atrophy was significantly greater (P < 0.05) in women with a BMI less than 25 kg/m compared with a BMI of 25 kg/m or greater. CONCLUSIONS: Lower- and standard-dose regimens of CE or CE/MPA are not associated with greater weight gain than placebo. In addition, BMI does not seem to influence effects of these regimens on vasomotor symptoms, vaginal atrophy, bleeding profiles, BMD, endometrial safety, or breast pain.

Abstract: OBJECTIVE: To evaluate the efficacy of lower doses of conjugated equine estrogens (CEE) plus medroxyprogesterone acetate (MPA) for relieving vasomotor symptoms and vaginal atrophy. DESIGN: A randomized, double-blind, placebo-controlled trial (the Women's Health, Osteoporosis, Progestin, Estrogen study). SETTING: Study centers across the United States. PATIENT(S): Two thousand, six hundred, seventy-three healthy, postmenopausal women with an intact uterus, including an efficacy-evaluable population (n = 241 at baseline).Intervention(s): Patients received for 1 year (13 cycles; in milligrams per day) CEE, 0.625; CEE, 0.625 and MPA, 2.5; CEE, 0.45; CEE, 0.45 and MPA, 2.5; CEE, 0.45 and MPA, 1.5; CEE, 0.3; CEE, 0.3 and MPA, 1.5; or placebo. MAIN OUTCOME MEASURE(S): Number and severity of hot flushes and Papanicolaou smear with vaginal maturation index (VMI) to assess vaginal atrophy. RESULT(S): In the efficacy-evaluable population, reduction in vasomotor symptoms was similar with CEE of 0.625 mg/d and MPA of 2.5 mg/d (the most commonly prescribed doses) and all lower combination doses. CEE of 0.625 mg/d alleviated hot flushes more effectively than the lower doses of CEE alone. VMI improved in all active treatment groups. CONCLUSION(S): Lower doses of CEE plus MPA relieve vasomotor symptoms and vaginal atrophy as effectively as commonly prescribed doses.

Abstract: INTRODUCTION: Arzoxifene, a benzothiophene estrogen agonist/antagonist, is being developed for prevention and treatment of osteoporosis and for risk reduction of invasive breast cancer in postmenopausal women. METHODS: The effects of arzoxifene 20 mg/d on bone mineral density (BMD), uterine safety, and overall safety were studied in the FOUNDATION study, a 2-yr randomized, placebo-controlled trial including 331 postmenopausal women with normal to low bone mass. RESULTS: Compared to placebo, arzoxifene significantly increased lumbar spine (+2.9%) and total hip (+2.2%) BMD. Arzoxifene decreased biochemical markers of bone metabolism compared to placebo. Changes in breast density were neutral or slightly decreased in the arzoxifene vs. placebo group. There was no evidence of endometrial hyperplasia or carcinoma in the arzoxifene group as assessed by central review of baseline and follow-up endometrial biopsies. There was no significant change between the groups in endometrial thickness assessed by transvaginal ultrasound. The incidence of uterine polyps and vaginal bleeding was not significantly different between the groups. Vulvovaginal mycotic infection was the only adverse event significantly increased in the arzoxifene vs. placebo group. Hot flushes were not significantly different between the groups. CONCLUSION: In postmenopausal women with normal to low bone mass, arzoxifene 20 mg/d increased BMD at the spine and hip and had a neutral effect on the uterus and endometrium.

Abstract: The double-blind, randomized raloxifene alendronate comparison trial was the first study designed to compare two osteoporosis therapies head-to-head for fracture risk reduction. The original protocol planned to treat 3000 postmenopausal women with alendronate 10 mg/day (ALN) or raloxifene 60 mg/day (RLX) for 5 years, and to recruit women (50-80 years old) with a femoral neck bone mineral density (BMD) T-score between -2.5 and -4.0, inclusive, no prevalent vertebral fractures, and no prior bone-active agent use. The trial was stopped early, due to difficulty in finding treatment-naïve women to meet enrollment goals within the planned timeline, resulting in insufficient power to show non-inferiority between therapies in the primary endpoint (number of women with >or=1 new osteoporotic vertebral or nonvertebral fracture). Except for vertebral fractures, fracture analyses were based upon 1412 of the 1423 women randomized (mean age of 66 years). After 312+/-254 days (mean+/-SD), 22 women in the ALN group and 20 in the RLX group had new vertebral or nonvertebral fractures. Four women in the ALN group and none in the RLX group had moderate/severe vertebral fractures, a pre-specified endpoint (P=0.04). Lumbar spine, femoral neck, and total hip BMD were increased from baseline at 2 years in each group (P<0.001), with greater increases in the ALN group (each P<0.05). Similar numbers of women in each group had >or=1 adverse event and discontinued due to an adverse event. The only adverse events with an incidence that differed between groups were colonoscopy, diarrhea, and nausea; each was more common with ALN treatment (each P<0.05). One woman in each group had a venous thromboembolic event. One case of breast cancer occurred in each group. In summary, as this trial was terminated early, there was insufficient power to compare the fracture risks between alendronate and raloxifene. Safety profiles were as expected from clinical trial and post-marketing reports. TRIAL REGISTRATION: ClinicalTrials.gov Identifier NCT00035971.
