Uterine bleeding is a common reason why women discontinue menopausal hormone therapy (HT). This systematic review compared bleeding profiles reported in studies for continuous-combined HT approved in North America and Europe for moderate to severe vasomotor symptoms in postmenopausal women with a uterus. Non-head-to-head studies showed that uterine bleeding varies by formulation and administration route, with oral having a better bleeding profile than transdermal formulations. Cumulative amenorrhea over a year ranged from 18 to 61% with oral HT and from 9 to 27% with transdermal HT, as reported for continuous-combined HT containing 17β-estradiol (E2)/progesterone (P4) (56%), E2/norethisterone acetate (NETA) (49%), E2/drospirenone (45%), conjugated equine estrogens/medroxyprogesterone acetate (18-54%), ethinyl estradiol/NETA (31-61%), E2/levonorgestrel patch (16%), and E2/NETA patch (9-27%). Amenorrhea rates and the mean number of bleeding/spotting days improved over time. The oral E2/P4 combination was amongst those with lower bleeding rates and may be an appropriate alternative for millions of women seeking bioidentical HT and/or those who have bleeding concerns with other HT.

The US Preventive Services Task Force (USPSTF) Draft Recommendation statement on Menopausal Hormone Therapy: Primary Prevention for Chronic Diseases, released in May 2017, perpetuates a major disconnect between the primary population affected, women within roughly 10 years of menopause, and the data cited. Furthermore, major elements of the evidence relied upon have been misinterpreted or misstated, particularly in regard to coronary heart disease and breast cancer, for which there is no statistically significant evidence of harm. As currently drafted, the recommendations reiterate the USPSTF statements of 2012, 2005 and 2002, and will perpetuate egregious harm to the public health. In an attempt to avoid that outcome and to facilitate a return to rational discourse regarding menopausal hormone therapy, an ad hoc group of experts in menopausal health submitted this comprehensive response to the USPSTF.

Prior to 1996, the use of postmenopausal estrogen was not believed to increase the risk of venous thrombosis. Subsequent studies, particularly the prospective, randomized, double-blind, clinical trial of the Women's Health Initiative, have clearly shown an increase in the incidence and risk of venous thrombosis in postmenopausal women using conjugated equine estrogens with or without medroxyprogesterone acetate. The risk of venous thrombosis in postmenopausal women is also increased by obesity and age. Oral hormone therapy has been used principally for management of menopausal symptoms. Transdermal estrogens have not been used as extensively in the United States but have a significant use in Europe. Recent observational studies have indicated no increased risk of venous thrombosis with use of transdermal estrogens. Norpregnane derivatives have been associated with an increased risk of venous thrombosis, suggesting that progestins may contribute to the increased risk in postmenopausal women using estrogen plus progestin therapy.

Premature menopause and bilateral oophorectomy in young women are associated with an increased incidence of cardiovascular disease, myocardial infarction and overall mortality. Observational studies suggest an interval of 5-10 years between loss of ovarian function and the increased risk of cardiovascular disease. This finding is consonant with a published autopsy study of women who had undergone bilateral oophorectomy. The progression of atherosclerosis is retarded with the use of estrogen replacement therapy in non-human primates and women. Hormone therapy reduced the incidence of cardiovascular disease in women following bilateral oophorectomy. These findings support the use of hormone therapy in young women who have lost ovarian function.

Objective: To evaluate the efficacy of two ultra-low-dose 17beta-estradiol plus norethisterone acetate (NETA) treatment regimens for relieving menopausal symptoms., Design: A total of 577 postmenopausal women were enrolled, in three treatment groups in a double-blind, randomized, placebo-controlled study of 0.5 mg 17beta-estradiol + 0.1 mg NETA or 0.5 mg 17beta-estradiol + 0.25 mg NETA or placebo. Participants returned at weeks 4, 8, 12 and 24 for climacteric complaint evaluation based on a daily diary vasomotor symptom record. Patients were assessed by the Greene Climacteric Scale and urogenital symptoms were also evaluated., Results: Treatment with ultra-low-dose 0.5 mg 17beta-estradiol + 0.1 mg NETA (0.1 Group) or 0.5 mg 17beta-estradiol + 0.25 mg NETA (0.25 Group) effectively reduced the severity and number of hot flushes within the initial weeks of therapy. Compared to placebo, a rapid, statistically significant decrease in the frequency and severity of hot flushes was achieved by week 3, followed by further improvement which continued throughout the study. There were no statistically significant differences between the active treatment arms., Conclusions: The data show that both ultra-low-dose regimens are effective in reducing the severity and number of hot flushes compared to placebo, with good safety profiles.

The efficacy of estrogen with or without a progestogen as hormone replacement therapy (HRT) for menopausal symptoms is well-established. Recent large-scale randomized studies with combined estrogen/progestogen therapy (EPT) have raised a number of safety issues, specifically the potential risk for coronary heart disease. Subsequent analyses and other studies have indicated that HRT may be cardioprotective in younger postmenopausal women. A new continuous EPT combines natural 17beta-estradiol (E2) 1 mg with the novel progestin, drospirenone (DRSP) either 0.5 or 2 mg. DRSP has a physiological profile closer to that of natural progesterone than any other synthetic progestin. This paper reviews recent clinical trial data demonstrating the efficacy and safety of combined DRSP/E2 therapy as EPT in postmenopausal women. DRSP/E2 provides symptomatic relief of vasomotor symptoms and improvement in genitourinary atrophy. DRSP/E2 protects against endometrial hyperplasia and reduces the risk of osteoporosis. Combined DRSP/E2 therapy has a favorable impact on cholesterol and triglyceride levels, and decreases blood pressure in women with elevated blood pressure. The favorable efficacy and safety profile of DRSP/E2, and potential for long-term health benefits, represents a new option for the effective management of menopause and its clinical sequelae.

Objectives: To systematically review methods used to report data on bleeding patterns among postmenopausal women enrolled in clinical trials of continuous combined hormone replacement therapy (HRT); and to propose the use of standardized terms, definitions, and methods for collecting and reporting bleeding data in such trials., Methods: A MEDLINE search identified 18 published reports of bleeding patterns among postmenopausal women enrolled in prospective clinical trials that included a continuous combined HRT treatment arm. Only two of these trials were not randomized. Methods for collecting and analyzing bleeding pattern data were collated from these published reports and examined for consistency., Results: Comparisons across studies revealed little consistency in definitions and indices utilized to report bleeding patterns among postmenopausal women administered continuous combined HRT regimens in clinical trials. While a majority of the trials incorporated definitions established by the World Health Organization for the evaluation of bleeding with hormonal contraception, a number of the studies expanded on these definitions to reflect additional dimensions of bleeding such as volume. Indices calculated from daily bleeding data to describe bleeding patterns in treatment groups were highly variable among studies., Conclusion: Inconsistencies among clinical trials in bleeding pattern definitions and indices limit understanding and comparison of typical bleeding patterns with continuous combined HRT regimens. Standardized definitions, data collection procedures, and indices are proposed to enhance understanding of bleeding patterns with hormone therapy and enrich the quality of patient counselling on HRT.

Objective: This study was designed to compare the bleeding profiles of conjugated equine estrogens 0.625 mg in combination with 2.5 mg medroxyprogesterone acetate (Prempro; CEE/MPA group), the most widely prescribed continuous combined hormone replacement therapy (CCHRT) in the United States, with 17beta-estradiol 1 mg combined with 0.5 mg norethindrone acetate (Activella; E(2)/NETA group), a newly available CCHRT preparation, over a 6-month period., Design: This study was a prospective, randomized, multicenter, double-blind, controlled trial. A total of 438 healthy postmenopausal women were randomized and received treatment (Activella n = 217, Prempro n = 221). Each woman recorded bleeding diaries daily. Total cholesterol, triglycerides, and endometrial biopsies were obtained at screening and end-of-trial visits., Results: The more favorable bleeding profile was found in the E(2)/NETA (Activella) group. The differences in bleeding patterns were most marked in the first 3 months of treatment in women who were 1-2 years from last menses, with no bleeding in 71.4% vs. 40.0%; ( p = 0.005) and with no bleeding and no spotting in 54.8% vs. 17.1%; (p = 0.001). Triglycerides fell by 8.5% in the E(2)/NETA group and increased by 11.7% in the CEE/MPA group (p < 0.001). Total cholesterol declined by 9.1% and 6.9%, respectively., Conclusion: The most important factor in the continuation of HRT is uterine bleeding. E(2)/NETA has significantly less bleeding than the most commonly prescribed CCHRT CEE/MPA, therefore; E(2)/NETA should be associated with improved continuation rates. The patient taking E(2)/NETA will receive effective treatment for her menopausal symptoms with less bleeding.

Objective: Women who have ever used estrogen replacement therapy (ERT), even at a low dose, have an increased incidence of endometrial cancer. The addition of a progestin to ERT reduces the incidence of endometrial cancer. The duration of progestin administration is more important than the dose., Design: A MEDLINE review of the literature was performed using the search terms endometrial cancer, epidemiology, and hormone replacement therapy (HRT)., Results: Women who have ever used ERT have an increased incidence of endometrial cancer. The use of HRT for more than 5 years, with a progestin use of <10 days per cycle, has a relative risk = 1.8. Continuous combined HRT, or sequential or cyclic HRT with >10 days of progestin per cycle, appears to decrease the incidence of endometrial cancer to that found in nonusers of HRT., Conclusions: The use of HRT in postmenopausal women with a uterus reduces the incidence of endometrial cancer. The duration of progestin administration should be 14 days or more per cycle based on recent epidemiologic data.

Objective: To analyze the effects of two continuous combined hormone replacement regimens on bleeding profiles in postmenopausal women, based on progestin dose and time since the patient's last spontaneous menstrual period., Methods: A randomized, double-masked, multicenter trial was conducted in 1724 women recruited from 99 sites. Six hundred seventy-eight women received a continuous regimen of oral conjugated equine estrogens (CEE), 0.625 mg/day, combined with medroxyprogesterone acetate (MPA), 2.5 or 5.0 mg/day, for 1 year., Results: After 1 year, no bleeding was reported by over 89% of women. More women in the 5.0 mg/day MPA group than in the 2.5 mg/day MPA group reported no bleeding (93.8% versus 89.5%; P<.089). Of those women who had had their last menstrual period 3 years ago or less, a significantly higher percentage in the 5.0 mg/day MPA group (72.4%) did not experience bleeding after three cycles compared with the 2.5 mg group (59.0%; P<.001). Although the percentage of patients without bleeding was also higher in the 5.0 mg/day MPA group after six cycles and 1 year, the differences between groups were not statistically significant. Of the women who had their last menstrual period more than 3 years ago, 94.7% of those in the 5.0 mg/day MPA group and 90.7% of those in the 2.5 mg/day MPA group reported no bleeding at 1 year., Conclusion: A continuous combined regimen of CEE plus 5.0 mg MPA may be more suitable for women closer to the onset of menopause or for women starting therapy who are unwilling to tolerate irregular bleeding. The improved bleeding profile with CEE and 5.0 mg/day MPA is likely to enhance compliance with hormone replacement therapy.

Objective: To identify the lowest effective continuous dose of norethindrone acetate that significantly reduces 12-month incidence of endometrial hyperplasia associated with unopposed 17beta-estradiol (E2), 1 mg., Methods: In a double-masked, randomized, multicenter study, 1176 healthy postmenopausal women 45 years of age or older without evidence of endometrial abnormalities were given 12 months of treatment with unopposed E2, 1 mg, or continuous-combined regimens of E2, 1 mg, and norethindrone acetate, 0.1 mg, 0.25 mg, or 0.5 mg. Endometrial histology was evaluated at the end of the treatment period., Results: Continuous-combined E2-norethindrone acetate regimens significantly reduced 12-month incidence of endometrial hyperplasia compared with unopposed E2 1 mg (P <.001). Endometrial hyperplasia occurred in 14.6% of women treated with unopposed E2 1 mg, whereas in all continuous-combined groups, the rate decreased to less than 1%. Among patients who received E2-norethindrone acetate 0.1 mg, incidence was 0.8%; among those who received 0.25 mg and 0.5 mg, it was 0.4%., Conclusion: Continuous norethindrone acetate at doses as low as 0.1 mg combined with E2 1 mg effectively negated risk for endometrial hyperplasia associated with unopposed E2 1 mg, at least for the first year of therapy.

Objective: To investigate the incidence of uterine bleeding during 12 months of treatment with 17beta-estradiol (E2) 1 mg, unopposed or in combination with three doses of norethindrone acetate., Methods: This study was a prospective, double-masked, randomized, multicenter trial. A total of 1176 healthy postmenopausal women age 45 years and older without evidence of endometrial abnormalities were randomly assigned to receive either unopposed E2 1 mg, or continuous-combined formulations of E2 1 mg and norethindrone acetate 0.1 mg, 0.25 mg, or 0.5 mg. Any spotting or bleeding episodes during the treatment period were recorded in a daily diary and reported by weekly telephone calls., Results: The incidence of bleeding was low in the combination groups, even during the initial 3 months of treatment (24-28%), after which it decreased with increasing doses of norethindrone acetate. Conversely, the incidence of bleeding increased over time with unopposed E2 1 mg. After the initial 3 months, the incidence of bleeding among the combination groups was lowest in the norethindrone acetate 0.5 mg group. Among women initiating therapy close to menopause, fewer reported bleeding with norethindrone acetate 0.5 mg than with the other combination groups. There was a significantly (P<.05) lower discontinuation rate due to bleeding in the norethindrone acetate 0.5 mg group compared with all other treatment groups., Conclusion: Continuous-combined formulations of E2 1 mg with norethindrone acetate 0.1, 0.25, or 0.5 mg are associated with a low incidence of uterine bleeding. After the initial 3 months of treatment, bleeding profiles improved with increasing doses of norethindrone acetate.

Objective: Our purpose was to evaluate the efficacy and safety of 3 dosages of Esclim, delivering 0.025 mg, 0.050 mg, or 0.100 mg 17beta-estradiol per 24 hours, in the treatment of moderate to severe vasomotor symptoms., Study Design: In this double-blind, placebo-controlled, parallel-group, multicenter trial, 196 highly symptomatic menopausal women received 12 weeks of continuous unopposed treatment with 1 of the 3 dosages of Esclim or a matching placebo patch., Results: The reduction in frequency of moderate to severe vasomotor symptoms was statistically significant compared with placebo (P <.05) from week 2 onward in the Esclim 50 and 100 groups and from week 3 onward in the Esclim 25 group. Symptom severity was also reduced. Estrogen-related adverse events, particularly metrorrhagia and endometrial hyperplasia, were less frequent in the Esclim 25 group than in the higher-dosage groups., Conclusion: All 3 dosages of Esclim were effective in the treatment of vasomotor symptoms. The efficacy and safety of Esclim 25 indicate a good risk-benefit ratio.

Objectives: The study retrospectively determined in postmenopausal women the cumulative amenorrhea patterns with continuous conjugated equine estrogens (CE) with or without continuous medroxyprogesterone acetate (MPA), and withdrawal bleeding patterns with cyclic therapy., Methods: During a 1-year, prospective trial, all patients took CE. Groups A and B also took continuous MPA 2.5 and 5 mg, respectively, C and D took MPA 5 and 10 mg for the last 14 cycle days, respectively, and E took placebo to match MPA., Results: By cycle 7, 40.4, 52.6 and 53.8% of women in Groups A, B and E, respectively, became amenorrheic. Percentages increased at each subsequent cycle. Of the remaining women in Groups A and B, 42.1 and 46.2%, respectively, experienced only spotting at cycle 7. In Groups C and D, 80 and 65.9%, respectively, had a mean change of equal to or less than 3 days in the onset of withdrawal bleeding/spotting from cycle to cycle for all 13 evaluable cycles., Conclusions: Amenorrhea is often desirable, and a continuous combined daily regimen of CE 0.625 mg + MPA 2.5 or 5 mg, which resulted in progressive increases in amenorrheic frequency during the 1-year treatment period, may promote compliance. In some women, however, the cyclic regimens, which produced fairly predictable withdrawal bleeding, may be preferable.

Objective: We evaluated bleeding as a predictor of endometrial hyperplasia in postmenopausal women receiving conjugated estrogens (Premarin) alone or with medroxyprogesterone acetate., Study Design: This study was a retrospective assessment of bleeding and endometrial histologic data gathered during the prospective Menopause Study Group trial., Results: Approximately 20% of women (n = 57) who received unopposed conjugated estrogens for 1 year had endometrial hyperplasia. These women (n = 56) had more bleeding days than did women who did not have hyperplasia (p < 0.001). For users of unopposed conjugated estrogens, the predictive value of amenorrhea to indicate a nonhyperplasia diagnosis was 95%. Irregular bleeding did not appear to be indicative of hyperplasia when continuous or cyclic medroxyprogesterone acetate was added to conjugated estrogens., Conclusion: Unanticipated prolonged bleeding in postmenopausal women receiving unopposed estrogen is suggestive of endometrial hyperplasia. Some irregular bleeding is anticipated in women who receive conjugated estrogens plus medroxyprogesterone acetate as they acclimate to therapy, and this was not associated with hyperplasia.

Objective: To compare the bleeding patterns obtained with two continuous combined and two sequential regimens of conjugated estrogens with medroxyprogesterone acetate (MPA) and conjugated estrogens alone., Methods: This was a 1-year double-blind, randomized study done with 1724 postmenopausal women at 99 sites in the United States and Europe. All five treatment groups received 0.625 mg/day of conjugated estrogens. Groups A and B also took continuous daily doses of 2.5 and 5.0 mg of MPA, respectively. Groups C and D took 5.0 and 10.0 mg of MPA, respectively, for the last 14 days of each 28-day cycle. Group E took continuous daily doses of placebo to match MPA., Results: The two continuous combined regimens (A and B) produced amenorrhea in 61.4 and 72.8%, respectively, of all evaluable cycles. Generally, the incidence of amenorrhea increased and irregular bleeding decreased with longer duration of treatment. In addition, amenorrhea occurred for at least the last seven consecutive cycles of the treatment year for about 40% of the patients taking the lower-dose continuous combined regimen (A), about 50% of the patients taking the higher-dose continuous combined regimen (B), and about 50% of the patients taking conjugated estrogens alone. About 5% of the patients who took either of the sequential regimens (C or D) had amenorrhea during that time. Most of the cycles (81.3 and 77.0% in groups C and D, respectively) for patients taking the sequential conjugated estrogens-MPA regimens had regular withdrawal bleeding or withdrawal spotting. There was no bleeding or spotting in 75.5% of the cycles for patients who took conjugated estrogens alone., Conclusions: Approximately half of the women who took the continuous combined conjugated estrogens-MPA regimens had amenorrhea, and the incidence tended to increase during the study. Women who took the sequential regimens had good cycle control with minimal irregular bleeding. More than half of those who took conjugated estrogens alone had amenorrhea.

The pharmacokinetics of three transdermal estradiol (E2) replacement regimens were studied following establishment of steady-state dynamics. Oestrogel 3.0 mg, Oestrogel 1.5 mg, and Estraderm transdermal delivery system 4 mg (0.05 mg/day) were administered for 14 days each to 15 postmenopausal volunteers, with a 14-day washout period between each regimen. The percutaneous E2 pharmacokinetics were compared with an oral micronized E2 preparation. Venous samples were obtained at 0, 1, 2, 4, 8, 12, and 24 hours on 3 sequential days 11 days after initial application of the Oestrogel and the transdermal delivery system, and at the same times after oral E2 ingestion. All three percutaneous regimens provided nearly constant serum E2 and estrone (E1) levels throughout their use. The mean serum E2 levels were 102.9 +/- 39.9, 68.1 +/- 27.4, and 41.1 +/- 13.5 pg/mL for Oestrogel 3.0 mg, Oestrogel 1.5 mg, and Estraderm, respectively. Oral E2 resulted in a mean serum E2 level of 114.0 +/- 65.2 pg/mL with marked peak and nadir values. The E1/E2 ratio was comparable with all three percutaneous regimens (1.08-1.33) and was significantly lower than that found with oral Estrace (5.05).

Recent observational studies have indicated no increased risk of venous thrombosis with use of transdermal estrogens. Norpregnane derivatives have been associated with an increased risk of venous thrombosis, suggesting that progestins may contribute to the increased risk in postmenopausal women using estrogen plus progestin therapy.

Objective An overview of the current knowledge on the etiology and treatment of vasomotor symptoms in postmenopausal women. Materials and methods Acknowledged experts in the fi eld contributed a brief assessment of their areas of interest which were combined and edited into the fi nal manuscript. Results Women around the world experience vasomotor symptoms as they enter and complete the menopause transition. Vasomotor symptoms, specifi cally hot fl ushes, are caused by a narrowing of the thermoneutral zone in the brain. This effect, although related to estrogen withdrawal, is most likely related to changes in central nervous system neurotransmitters. Peripheral vascular reactivity is also altered in symptomatic women. Estrogen replacement therapy is the most effective treatment for hot fl ushes. Of the other interventions investigated, selective serotonin and selective norepinephrine reuptake inhibitors and gabapentin show effi cacy greater than placebo. Objective monitoring of hot fl ushes indicates a robust improvement with hormone replacement therapy but little to no change with placebo. These data suggest that the subjective assessment of responses to therapy for vasomotor symptom results in inaccurate data. Hot fl ushes have recently been associated with increased cardiovascular risks and a lower incidence of breast cancer, but these data require confi rmation. Conclusions Vasomotor symptoms are experienced by women of all ethnic groups. They are caused by changes in the central nervous system associated with estrogen withdrawal and are best treated with estrogen replacement therapy. Objective monitoring of hot fl ushes indicates that placebo has little to no effect on their improvement. Subjective assessments of hot fl ushes in clinical trials may be inaccurate based on objective measurement of the frequency of hot fl ushes. Based on preliminary reports, women experiencing hot fl ushes have an increased risk of cardiovascular disease and a reduced incidence of breast cancer. [ABSTRACT FROM AUTHOR]

Premature menopause and bilateral oophorectomy in young women are associated with an increased incidence of cardiovascular disease, myocardial infarction and overall mortality, Observational studies suggest an interval of 5-10 years between loss of ovarian function and the increased risk of cardiovascular disease. This finding is consonant with a published autopsy study of women who had undergone bilateral oophorectomy. The progression of atherosclerosis is retarded with the use of estrogen replacement therapy in non-human primates and women. Hormone therapy reduced the incidence of cardiovascular disease in women following bilateral oophorectomy. These findings support the use of hormone therapy in young women who have lost ovarian function. [ABSTRACT FROM AUTHOR]

Objective: This study was undertaken to evaluate the effects on hemostatic factors of a low-dose preparation of levonorgestrel and ethinyl estradiol in a 12-cycle study.Study Design: Thirty healthy women began taking 100 microg levonorgestrel and 20 microg ethinyl estradiol on the first day of the menstrual cycle, continued to take the preparation for the next 21 days, and then took placebo for 7 days. Mean changes in prothrombin time, partial thromboplastin time, and levels of factors VII and X, antithrombin, plasminogen, fibrinogen, protein S, thrombin-antithrombin complexes, and D-dimer were analyzed at baseline and at cycles 3, 6, and 12 with paired Student t tests.Results: Factor X, plasminogen antigen and activity, and D-dimer levels were significantly increased (P Conclusion: The effects on hemostatic factors in healthy women of a monophasic preparation of 100 microg levonorgestrel and 20 microg ethinyl estradiol were similar to those of other low-dose oral contraceptives.

Menopause is merely a clinically discernible clue symbolic of the multitude of changes preceding or following the cessation of menses by many years. Because of the time span involved, separating changes observed in the menopausal transition from other age-related maturational events presents serious methodologic problems. Of the host of psychologic and psychosomatic symptoms, only hot flushes and associated sweats occur more frequently in this epoch, while an interplay between hormonal and age-related maturational events presents serious methodologic problems. Of the host of psychologic and psychosomatic symptoms, only hot flushes and associated sweats occur more frequently in this epoch, while an interplay between hormonal and age-related effects is assumed in atrophic changes involving the genitourinary organs. The relation between menopause and osteoporosis is suggestive but by no means proven, as is the risk for cardiovascular disease. Empiric evidence points to the usefullness of estrogen for the management of vasomotor instability, the symptoms associated with atrophy of the genitourinary tract, and in the prophylaxis of osteoporosis, but not in the treatment of anxiety, depression, and other psychiatric disorders.
