Mueck AO, Römer T. Choice of progestogen for endometrial protection in combination with transdermal estradiol in menopausal women. Horm Mol Biol Clin Investig 2018; 37:hmbci-2018-0033. [PMID: 30063464 DOI: 10.1515/hmbci-2018-0033] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2018] [Accepted: 06/18/2018] [Indexed: 01/14/2023]
Abstract
Transdermal estradiol (TE) application (using gels, patches or a novel spray) is now a preferred route of hormone therapy (HT) in menopausal women, because various risks such as venous thromboembolism, stroke and unwanted hepatic effects can be reduced compared with oral HT. However, in the presence of an intact uterus, concurrent administration of progestogen is needed for endometrial protection. Due to the variety of progestogens available and differences in their clinical effects, the selection of the most appropriate substance and dosing for individual combination therapy can be difficult. This is especially true for TE gels and the novel spray because no fixed combination products are commercially available, meaning all progestogens must be added separately, and even for patches only two transdermal synthetic progestogens are available. The aim of this review was to summarize data on the endometrial effects of the different progestogens and to provide practical recommendations for the choice of progestogen (type and dosing), with a focus on endometrial protection when using TE, especially when using the novel estradiol (E2) spray.

Abstract
BACKGROUND Several evaluations of the cost-effectiveness (CE) of menopausal hormone therapy (MHT) have been reported. The aim of this study was to systematically and critically review economic evaluations of MHT since 2002, after the Women's Health Initiative (WHI) trial results on MHT were published. METHODS The inclusion criteria for the review were: CE analyses of MHT versus no treatment, published from 2002-2016, in healthy women, which included both symptom relief outcomes and a range of longer term health outcomes (breast cancer, coronary heart disease, stroke, fractures and colorectal cancer). Included economic models had outcomes expressed in cost per quality-adjusted life year or cost per life year saved. MEDLINE, EMBASE, Evidence-Based Medicine Reviews databases and the Cost-Effectiveness Analysis Registry were searched. CE evaluations were assessed in regard to (i) reporting standards using the CHEERS checklist and Drummond checklist; (ii) data sources for the utility of MHT with respect to menopausal symptom relief; (iii) cost derivation; (iv) outcomes considered in the models; and (v) the comprehensiveness of the models with respect to factors related to MHT use that impact long term outcomes, using breast cancer as an example outcome. RESULTS Five studies satisfying the inclusion criteria were identified which modelled cohorts of women aged 50 and older who used combination or estrogen-only MHT for 5-15 years. For women 50-60 years of age, all evaluations found MHT to be cost-effective and below the willingness-to-pay threshold of the country for which the analysis was conducted. However, 3 analyses based the quality of life (QOL) benefit for symptom relief on one small primary study. Examination of costing methods identified a need for further clarity in the methodology used to aggregate costs from sources. Using breast cancer as an example outcome, risks as measured in the WHI were used in the majority of evaluations. Apart from the type and duration of MHT use, other effect modifiers for breast cancer outcomes (for example body mass index) were not considered. CONCLUSIONS This systematic review identified issues which could impact the outcome of MHT CE analyses and the generalisability of their results. The estimated CE of MHT is driven largely by estimates of QOL improvements associated with symptom relief but data sources on these utility weights are limited. Future analyses should carefully consider data sources and the evidence on the long term risks of MHT use in terms of chronic disease. This review highlights the considerable difficulties in conducting cost-effectiveness analyses in situations where short term benefits of an intervention must be evaluated in the context of long term health outcomes.

Abstract
OBJECTIVE Our objective was to review the involved mechanisms and propose actions for controlling/treating abnormal uterine bleeding during climacteric hormone therapy. METHODS A systemic search of the databases SciELO, MEDLINE, and Pubmed was performed for identifying relevant publications on normal endometrial bleeding, abnormal uterine bleeding, and hormone therapy bleeding. RESULTS Before starting hormone therapy, it is essential to exclude any abnormal organic condition, identify women at higher risk for bleeding, and adapt the regimen to suit eachwoman's characteristics. Abnormal bleeding with progesterone/progestogen only, combined sequential, or combined continuous regimens may be corrected by changing the progestogen, adjusting the progestogen or estrogen/progestogen doses, or even switching the initial regimen to other formulation. CONCLUSION To diminish the occurrence of abnormal bleeding during hormone therapy (HT), it is important to tailor the regimen to the needs of individual women and identify those with higher risk of bleeding. The use of new agents as adjuvant therapies for decreasing abnormal bleeding in women on HT awaits future studies.

Abstract
BACKGROUND Reduced circulating estrogen levels around the time of the menopause can induce unacceptable symptoms that affect the health and well-being of women. Hormone therapy (both unopposed estrogen and estrogen/progestogen combinations) is an effective treatment for these symptoms, but is associated with risk of harms. Guidelines recommend that hormone therapy be given at the lowest effective dose and treatment should be reviewed regularly. The aim of this review is to identify the minimum dose(s) of progestogen required to be added to estrogen so that the rate of endometrial hyperplasia is not increased compared to placebo. OBJECTIVES The objective of this review is to assess which hormone therapy regimens provide effective protection against the development of endometrial hyperplasia or carcinoma. SEARCH METHODS We searched the Cochrane Menstrual Disorders and Subfertility Group trials register (searched January 2012), The Cochrane Library (Issue 1, 2012), MEDLINE (1966 to January 2012), EMBASE (1980 to January 2012), Current Contents (1993 to May 2008), Biological Abstracts (1969 to 2008), Social Sciences Index (1980 to May 2008), PsycINFO (1972 to January 2012) and CINAHL (1982 to May 2008). Attempts were made to identify trials from citation lists of reviews and studies retrieved, and drug companies were contacted for unpublished data. SELECTION CRITERIA Randomised comparisons of unopposed estrogen therapy, combined continuous estrogen-progestogen therapy, sequential estrogen-progestogen therapy with each other or placebo, administered over a minimum period of 12 months. Incidence of endometrial hyperplasia/carcinoma assessed by a biopsy at the end of treatment was a required outcome. Data on adherence to therapy, rates of additional interventions, and withdrawals owing to adverse events were also extracted. DATA COLLECTION AND ANALYSIS In this update, 46 studies were included. Odds ratios (ORs) were calculated for dichotomous outcomes. The small numbers of studies in each comparison and the clinical heterogeneity precluded meta-analysis for many outcomes. MAIN RESULTS Unopposed estrogen is associated with increased risk of endometrial hyperplasia at all doses, and durations of therapy between one and three years. For women with a uterus the risk of endometrial hyperplasia with hormone therapy comprising low-dose estrogen continuously combined with a minimum of 1 mg norethisterone acetate (NETA) or 1.5 mg medroxyprogesterone acetate (MPA) is not significantly different from placebo at two years (1 mg NETA: OR 0.04; 95% confidence interval (CI) 0 to 2.8; 1.5 mg MPA: no hyperplasia events). AUTHORS' CONCLUSIONS Hormone therapy for postmenopausal women with an intact uterus should comprise both estrogen and progestogen to reduce the risk of endometrial hyperplasia.

Abstract
Objective To establish the effect on bone mineral density (BMD) of long-term (nine years) continuous-combined hormone replacement therapy (ccHRT) with estradiol valerate/medroxyprogesterone acetate (E2V/MPA) and follow-up one year after discontinuation of ccHRT. Study design A total of 279 women were treated with daily dosages of E2V + MPA: 1 mg + 2.5 mg (n = 69), 1 mg + 5 mg (n = 70) or 2 mg + 5 mg (n = 140) (Indivina®, Orion Pharma, Espoo, Finland) for 8.5 years; all subjects received the lowest dosage for the next six months. BMD was measured at baseline, between 6 and 12 months, annually until the end of study and at one-year postdiscontinuation of ccHRT. Main outcome measure Change in BMD during nine years of treatment with ccHRT and at one-year post-discontinuation of ccHRT. Results Progressive increase of vertebral BMD was observed with all dosage regimens throughout nine years, with corresponding reduction in the proportion of women fulfilling criteria for osteoporosis or osteopaenia. Femoral neck BMD reached a peak at about five to six years, whereas in the lumbar spine the BMD increase was sustained until the end of the study treatment. Mean BMD declined after cessation of ccHRT use but remained substantially above baseline levels. In a subset of women (n = 58) there was a rapid (≤4%) loss of vertebral BMD in the year after termination of ccHRT use. These women had lower than average BMD at baseline but no other factor was identified that distinguished them from the overall study population. Conclusions Low-dose ccHRT in postmenopausal women is associated with increases in lumbar spine BMD for at least nine years. These gains are not sustained after cessation of therapy but the rate of BMD loss varies between individuals.

Abstract
As girls with severe cognitive developmental delay progress into puberty and become young women with learning disabilities, concerns about menstruation are common amongst carers and health care professionals are often consulted for advice. Very little, however, has been published on this area to guide the practitioner and studies are almost exclusively confined to the gynaecological literature. We aim to give an account of the various therapeutic options available and current practice within the paediatric endocrinology unit at our institution.

Abstract
OBJECTIVES Current recommendations for hormone therapy (HT) are mainly based on findings from studies using standard dose regimens in older women who had a different health profile from those who start HT soon after the onset of menopause. METHODS We, therefore, reviewed controlled trials assessing the efficacy, safety and tolerability of low-dose oral continuous combined HT (cc-HT) started for treatment of climacteric symptoms. This review is limited to oral cc-HT regimens over sequential regimens as most postmenopausal women prefer not to have a return of uterine bleeding, and to studies of at least 2 years in duration. RESULTS Low-dose cc-HT is effective in alleviating climacteric symptoms and in maintaining bone density over prolonged periods, although no data were available regarding fracture risk. No increased risk of coronary heart disease, venous thrombo-embolism or stroke during the use of low-dose cc-HT was reported in the long-term studies and no definitive evidence for an increased risk of breast cancer was found. Breakthrough bleeding during the first months of use is less common than with standard dose HT and amenorrhoea is achieved in most women over time. These regimens are safe for the endometrium and are well tolerated, with a low incidence of adverse events compared with standard doses. CONCLUSIONS Current evidence from controlled trials indicates that low-dose oral cc-HT appears effective and safe. This makes it a good choice for the alleviation of climacteric symptoms, and for this purpose long-term administration of low-dose cc-HT does not seem to impose serious health risks. However, more long-term study data and direct head-to-head comparisons between various low-dose preparations are needed to support or rectify the safety aspects.

Abstract
Since the results of the women health initiative study showing an overall negative risk-benefit ratio with 0.625 mg of conjugated estrogens plus 2.5mg of medroxyprogesterone acetate, the use of the lowest effective dose of steroids in hormone replacement therapy (HRT) is recommended. A low-dose regimen appears to induce less side effects such as breast tenderness or leg pain than do higher dose preparations. The decrease in hot flashes with low-dose estrogens, range 60-70%, is less than the 80-90% reduction with standard dosing. But this mean that 60-70% of menopausal women do not need higher doses. The same applies to bone preservation which is dose dependent: the number of non-respondant women will be higher than with standard doses. However, randomized double-blind, placebo controls trials have defined positive effects on bone of low doses of HRT with adequate calcium and Vitamin D in elderly women. The use of bone densitometry and of biochemical markers of bone turnover is mandatory in women using low or ultra-low-dose preparations. In spite of the lack of trials conducted with low-dose HRT, this treatment seems to be safer: Beside the low-dose HRT, one must consider some other facts: In the future, it is conceivable that more comprehensive pharmacogenomic studies will lead to effective algorithms for individualizing the right dose of steroids to be used in HRT.

Abstract
OBJECTIVE To compare the metabolic effects of two frequently used continuous hormone replacement therapies. MATERIALS AND METHODS Two hundred and forty-six menopausal women, aged between 41 and 57 years were enrolled in the present study. They were randomized to receive either estrogen + 2.5 mg medroxyprogesterone acetate (CEE/MPA) or 1 mg 17 <beta> estradiol + 0.5 mg norethindrone acetate (E2/NETA). Women in group I (n = 139) and group II (n = 107) were followed up for 1 year and compared with respect to total cholesterol, triglycerides, HDL, LDL, VLDL, weight gain during this period. RESULTS The basal and 12th month weight of the patients of two groups were not statistically different (P = 0.57 and P = 0.17, respectively, in the groups I and II). No changes were detected in the levels of triglycerides, HDL and VLDL, while total cholesterol (P = 0.01) and LDL (P = 0.003) levels significantly decreased in the CEE/MPA group. In group 2, total cholesterol and triglyceride levels showed no significant change, however, levels of HDL cholesterol (P = 0.001) increased and LDL (P = 0.001) and VLDL cholesterol (P = 0.006) decreased significantly. CONCLUSION Administration of E2/NETA regimen has better results on lipid profile when compared to CEE/MPA regimen. No weight gain is recorded in E2/NETA group.

Abstract
OBJECTIVES To study the effect of standard and low-dose estrogen-progestin therapy (EPT), tibolone and raloxifene on the incidence of vaginal spotting/bleeding and endometrial thickness over a 5-year period. METHODS Seven hundred eighty-six postmenopausal women were studied in an open prospective design. Vaginal spotting/bleeding and endometrial thickness as assessed by transvaginal ultrasonography was compared between six categories of women over a 5-year period: three categories in women on continuous combined estrogen-progestin therapy, one category under tibolone, one category under raloxifene and one under no treatment. More specifically, women received tibolone 2.5 mg (N = 204), raloxifene HCl 60 mg (N = 137), conjugated equine estrogens 0.625 mg/medroxyprogesterone acetate 5mg (N = 122), 17beta-estradiol 2mg/norethisterone acetate 1mg (N = 58), 17beta-estradiol 1mg/norethisterone acetate 0.5mg (N = 76) or no therapy (controls, N = 189). Women with suspected endometrial pathology were referred for hysteroscopy. RESULTS Bleeding/spotting incidence was highest among standard dose EPT users (conjugated equine estrogens 0.625 mg/medroxyprogesterone acetate 5mg: 40.1%, 17beta-estradiol 2mg/norethisterone acetate 1mg: 44.8%, p < 0.001 compared to controls). Low-dose EPT associated with lower incidence of spotting/bleeding (34.1%). The incidence under tibolone and raloxifene was 22.5% and 2.9%, respectively, while 3.2% of women not receiving therapy reported vaginal spotting/bleeding. Mean endometrial thickness was not significantly affected in any of the groups studied. The drop-out rate due to spotting/bleeding was higher in the two higher dose EPT regimens. After logistic regression analysis, age at baseline was the only significant predictor of subsequent spotting/bleeding (b = -0.25, S.E. = 0.09, p = 0.006), while menopausal age and pre-treatment serum FSH had marginal significance. CONCLUSIONS EPT, tibolone and raloxifene do not appear to associate with significant changes in endometrial thickness in the majority of cases. The low-dose EPT regimen associated with a decreased incidence of unscheduled spotting/bleeding compared to the standard dose regimens. Tibolone expressed a favorable endometrial profile, as seen in its effect on unscheduled spotting/bleeding and mean endometrial thickness. Raloxifene associated with the lowest incidence in S/B and the lowest drop-out rate.s.

Abstract
OBJECTIVES The aim of the study was to confirm the endometrial safety and describe the bleeding profile of continuous combined 1 mg 17beta-oestradiol and 5 mg dydrogesterone in post-menopausal women. METHODS An open, multicentre study was carried out in 290 healthy, non-hysterectomised post-menopausal women receiving oral continuous combined 1 mg 17beta-oestradiol and 5 mg dydrogesterone (Femoston-conti) for 1 year. Aspiration endometrial biopsies were performed at baseline and at the end of the study; those classified as hyperplasia or malignancy were considered treatment failures. RESULTS Only one woman developed simple hyperplasia without atypia at the end of the study; the treatment failure rate was therefore 0.4%. Cross-sectional analysis showed that the percentage of women without bleeding increased from 71% during the first cycle to around 80% by the end of the study. Approximately 50% of the bleeding episodes occurred in the form of spotting; severe bleeding was rare and only seven women withdrew prematurely from the study due to uterine bleeding. Overall, 41% of the women were amenorrhoeic throughout the study. CONCLUSIONS Continuous combined 1 mg 17beta-oestradiol and 5 mg dydrogesterone provides excellent endometrial safety and is associated with an acceptable bleeding profile.

Abstract
OBJECTIVE : To evaluate the effects on monthly bleeding of four different progestogens administered in association with transdermal estradiol in a continuous sequential estrogen-progestin therapy (CS-EPT). DESIGN : This prospective, open, randomized, clinical trial included 100 healthy postmenopausal women. Patients were randomized into four treatment groups, each consisting of 25 women. Treatment consisted of 50 mug/day transdermal 17beta-estradiol for all women combined to receive four different progestogens (group A: medroxyprogesterone acetate, 10 mg/day; group B: nomegestrol acetate, 5 mg/day; group C: dydrogesterone, 10 mg/day; group D: micronized progesterone, 200 mg/day) per os from the 14th to 25th day of each 28-day cycle. The duration of treatment was 12 cycles. Patients were asked to record in a daily diary the occurrence of any vaginal bleeding, the days of application of each patch, the days of assumption of the different progestogens, and the exact moment of bleeding onset. RESULTS : A total of 937 cycles could be evaluated. In 690 cycles (73.6%), regular progestogen-related bleeding was reported. Among the other cycles, we observed 73 episodes of amenorrhea (7.8%, each one lasting one cycle), 78 episodes of irregular bleeding (8.3%), and 96 episodes of spotting (10.2%). Patients receiving nomegestrol acetate had a significantly higher incidence of regular progestogen-associated bleeding in comparison with those receiving medroxyprogesterone acetate or natural progesterone, and patients receiving dydrogesterone had a significantly higher incidence of regular progestogen-associated bleeding in comparison with those receiving natural progesterone. CONCLUSION : Our data suggest that CS-EPT generally leads to regular withdrawal bleeding in women without uterine pathology. Micronized progesterone seems to induce more irregular bleeding episodes.

Abstract
OBJECTIVES To study changes in: (i) the prevalence of hormone-replacement therapy (HRT) and (ii) women's attitudes and knowledge about the climacteric. Design. Cross-sectional comparison was performed on two populations of women both aged 46-62 years and resident in the same urban Swedish population over a period of 6 years. MATERIAL AND METHODS In 1992, a random sample of 5990 women, from five birth cohorts, 46, 50, 54, 58, and 62 years in the city of Göteborg, were assessed using a postal questionnaire technique. In 1998, the same technique was used and a similar questionnaire was sent to another cohort of women (n=5411) of the same ages, resident in the city of Göteborg. The overall response rate was 76%. Information was obtained regarding climacteric symptoms, HRT use, and attitudes and knowledge. RESULTS The prevalence of HRT use with medium-potency estrogens had increased from 13% (1992) to 31% (1998). The highest prevalence was reported in women 54 years of age (46%). The most common reasons why women started HRT were: hot flushes and sweats, depression/irritability, sleeping disturbances, and vaginal dryness. Forty-four percent of the women in this study were prepared to consider extended HRT if the treatment was free from withdrawal bleedings (35%, 1992). Eighty percent believed that the risk of osteoporosis decreased during HRT use (61%, 1992) and 68% thought that the risk of breast cancer increased (58%, 1992). CONCLUSIONS A marked increase in the use of HRT was reported between 1992 and 1998. Women's attitudes to HRT were more positive in 1998 compared to 1992. Knowledge about HRT among women had increased during the same 6-year period.

Abstract
OBJECTIVES To study whether ageing affects the pharmacokinetics of estradiol valerate (E2V) or medroxyprogesterone acetate (MPA) in postmenopausal women. METHODS Forty-six postmenopausal women from two essentially similar pharmacokinetic studies were divided into three age categories: under 60 years (n = 15), between 60 and 65 years (n = 18) and over 65 years (n = 13). They all were treated for 12 days or 14 days with four galenically identical tablets containing combinations of 1 mg or 2 mg E2V and 2.5 mg or 5 mg MPA. The studies followed an open, randomised cross-over design with no washout between the periods. Serum estradiol and MPA concentrations were measured at steady state on study day 12 or 14 of each period. RESULTS No statistically significant differences were observed in the peak concentration (Cmax), time to peak (t(max)), AUC or elimination half-life for estradiol or MPA between the different age groups. In spite of the lack of statistical significance the AUC was on an average 1.6-fold and Cmax 1.40-fold higher in the oldest group of women than in the youngest group and age was found significant as a continuous variable for AUC and Cmax for MPA but not for estradiol. CONCLUSIONS The results suggest that there would be no significant changes in the pharmacokinetics of estradiol between women under 60 and over 65 years of age. However, a significant trend towards higher MPA concentrations and bioavailability was observed with increasing age. The results suggest that from the pharmacokinetic point of view the relationship between estradiol and MPA dose to be used in elderly could be different from that in younger postmenopausal women, while no pharmacokinetic reasons to use lower estradiol doses in the elderly were observed.

Abstract
BACKGROUND The decline in circulating oestrogen around the time of the menopause often induces unacceptable symptoms that affect the health and well being of women. Hormone replacement therapy (both unopposed oestrogen and oestrogen and progestogen combinations) is an effective treatment for these symptoms. In women with an intact uterus, unopposed oestrogen may induce endometrial stimulation and increase the risk of endometrial hyperplasia and carcinoma. The addition of progestogen reduces this risk but may cause unacceptable symptoms, bleeding and spotting which can affect adherence to therapy. OBJECTIVES The objective of this review is to assess which hormone replacement therapy regimens provide effective protection against the development of endometrial hyperplasia and/or carcinoma with a low rate of abnormal vaginal bleeding. SEARCH STRATEGY We searched the Cochrane Menstrual Disorders and Subfertility Group trials register (searched January 2003), The Cochrane Library (Issue 2, 2003), MEDLINE (1966 to January 2003), EMBASE (1980 to January 2003), Current Contents (1993 to January 2003), Biological Abstracts (1969 to 2002), Social Sciences Index (1980 to January 2003), PsycINFO (1972 to February 2003) and CINAHL (1982 to January 2003). The search strategy was developed by the Cochrane Menstrual Disorder and Subfertility Group. Attempts were also made to identify trials from citation lists of review articles and drug companies were contacted for unpublished data. In most cases, the corresponding author of each included trial was contacted for additional information. SELECTION CRITERIA The inclusion criteria were randomised comparisons of unopposed oestrogen therapy, combined continuous oestrogen-progestogen therapy and sequential oestrogen-progestogen therapy with each other and placebo administered over a minimum treatment period of six months. Trials had to assess which regimen was the most protective against the development of endometrial hyperplasia/carcinoma and/or caused the lowest rate of irregular bleeding. DATA COLLECTION AND ANALYSIS Sixty RCTs were identified. Of these 23 were excluded and seven remain awaiting assessment. The reviewers assessed the thirty included studies for quality, extracted the data independently and odds ratios for dichotomous outcomes were estimated. Outcomes analysed included frequency of endometrial hyperplasia or carcinoma, frequency of irregular bleeding and unscheduled biopsies or dilation and curettage, and adherence to therapy. MAIN RESULTS Unopposed moderate or high dose oestrogen therapy when compared to placebo was associated with a significant increase in rates of endometrial hyperplasia with increasing rates at longer duration of treatment and follow up. Odds ratios ranged from (1 RCT; OR 5.4, 95% CI 1.4 to 20.9) for 6 months of treatment to (4 RCTs; OR 9.6, 95% CI 5.9 to 15.5) for 24 months treatment and (1 RCT; OR 15.0, 95% CI 9.3 to 27.5) for 36 months of treatment with moderate dose oestrogen (in the PEPI trial, 62% of those who took moderate dose oestrogen had some form of hyperplasia at 36 months compared to 2% of those who took placebo). Irregular bleeding and non adherence to treatment were also significantly more likely under these unopposed oestrogen regimens that increased bleeding with higher dose therapy. Although not statistically significant, there was a 3% incidence (2 RCTs) of hyperplasia in women who took low dose oestrogen compared to no incidence of hyperplasia in the placebo group. The addition of progestogens, either in continuous combined or sequential regimens, helped to reduce the risk of endometrial hyperplasia and improved adherence to therapy. At longer duration of treatment, continuous therapy was more effective than sequential therapy in reducing the risk of endometrial hyperplasia. There was evidence of a higher incidence of hyperplasia under long cycle sequential therapy (progestogen given every three months) compared to monthly sequential therapy (progestogen given every month). No increase in endometrial cancer was seen in any of t in any of the treatment groups during the duration (maximum of six years) of these trials. During the first year of therapy irregular bleeding and spotting was more likely in continuous combined therapy than sequential therapy. However, during the second year of therapy bleeding and spotting was more likely under sequential regimens. REVIEWERS' CONCLUSIONS There is strong and consistent evidence in this review that unopposed oestrogen therapy, at moderate and high doses, is associated with increased rates of endometrial hyperplasia, irregular bleeding and consequent non adherence to therapy. The addition of oral progestogens administered either sequentially or continuously is associated with reduced rates of hyperplasia and improved adherence to therapy. Irregular bleeding is less likely under sequential than continuous therapy during the first year of therapy but there is a suggestion that continuous therapy over long duration is more protective than sequential therapy in the prevention of endometrial hyperplasia. Hyperplasia is more likely when progestogen is given every three months in a sequential regimen compared to a monthly progestogen sequential regimen.

Abstract
PURPOSE To examine the factors that influence Hispanic women's decisions to initiate or not initiate hormone replacement therapy (HRT) during menopause to manage symptoms or to prevent longer-term conditions. DATA SOURCES A descriptive study of 51 Hispanic women who completed the Spanish version of the Menopausal Decision-Making Questionnaire (S-MDMQ) to describe their experience with and perceptions about menopause. CONCLUSIONS Most of the low-income Hispanic women in this study would elect not to take HRT; however, they do use exercise, diet, vitamins, and other self-care activities to manage symptoms of menopause. Hispanic women were eager to discuss how to manage their health care during perimenopause and menopause with one another and their health care providers. IMPLICATIONS FOR PRACTICE Nurse practitioners need to understand factors that might influence Hispanic women's decisions regarding management of menopausal symptoms, including the use of HRT, and to be able to assist women in making an individualized personal treatment choice that is culturally acceptable.

Abstract
OBJECTIVE To study the effect of 17beta-estradiol+norethisterone acetate and raloxifene on the endometrium and uterine volume in postmenopausal women. METHODS Patients were randomly assigned to 17beta-estradiol 2 mg+norethisterone acetate 1mg (E2+NETA) daily (n=90) or raloxifene HCl 60 mg (Evista) daily (n=43). Transvaginal sonography was done at baseline and at 6, 12 and 18 months, and at 6 and 12 months in-patients treated with E2+NETA and EVISTA respectively. Patients were asked to record bleeding-spotting episodes. Whenever required patients were referred for hysteroscopy+/-biopsy of the endometrium. RESULTS Patients under E2+NETA had a higher bleeding-spotting incidence (48.6%) compared with EVISTA (7.7%). Endometrial thickness increased significantly under E2+NETA as compared with baseline; however, at end point thickness reverted to baseline values. Evista had a non-stimulatory effect on the endometrium. Changes in uterine volume were not statistically significant. CONCLUSIONS Both treatment regimens provided comparable uterine safety. However, raloxifene exhibited a more favorable safety profile on the uterus as expressed in the bleeding-spotting incidence and the effect on endometrial thickness and uterine volume. Transvaginal sonography appears to be a dependable method for monitoring the effect of treatment on the uterus.

Abstract
BACKGROUND Progestogens are used clinically for contraception, to control excessive menstrual bleeding, and to prevent estrogen-induced endometrial hyperplasia. A significant problem with progestogen-only methods of contraception is the induction of breakthrough bleeding. METHODS The effects of different progestogens on angiogenesis were examined using two approaches. The mouse sponge angiogenesis assay employed direct delivery of the dose ranges achieved therapeutically. The angiogenic response to long-term intrauterine levonorgestrel exposure, compared with unexposed premenopausal endometrium, was also studied. RESULTS In the mouse sponge assay, norethisterone and medroxyprogesterone acetate stimulated angiogenesis at all doses, but was dose-dependent for levonorgestrel and nomegestrol. Levonorgestrel stimulated angiogenesis in the dose range 100 pmol/l to 10 nmol/l, but not at higher doses. In contrast, nomegestrol acetate stimulated angiogenesis at high, but not low, doses. Expression of acidic and basic fibroblast growth factors, thymidine phosphorylase, vascular endothelial growth factor and adrenomedullin were unaltered in levonorgestrel-exposed endometrium compared with premenopausal controls. Vascular density was increased but endothelial proliferation reduced in levonorgestrel-exposed endometrium. CONCLUSIONS This is the first report of the direct effects of a wide range of doses of different progestogens on angiogenesis; results suggest that vascular targeting may be an effective strategy to deal with progestogen-induced abnormal bleeding.

Abstract
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.

Abstract
OBJECTIVES We compared two different continuous combined hormone replacement therapy (HRT) regimens of estradiol valerate (E(2)V) and medroxyprogesterone acetate (MPA) with a combination of micronized estradiol (E(2)) and norethisterone acetate (NETA) to determine bleeding pattern, control of climacteric symptoms, lipid profile, endometrial and general safety in a 1-year multicenter study. METHODS 440 postmenopausal women were randomized to three treatment groups to receive: 1 mg E(2)V+2.5 mg MPA; 1 mg E(2)V+5 mg MPA; or 2 mg of E(2)+1 mg NETA. After the first 6 months, the E(2)V dose was increased to 2 mg in both E(2)V/MPA groups. Information on bleeding was recorded on diaries by the women and intensity of climacteric symptoms was assessed using VAS scales. Physical and laboratory examinations, endometrial biopsy and vaginal ultrasonography were performed at baseline and follow-up visits. RESULTS Significantly fewer bleeding days were experienced in the first 3 months by women taking E(2)V/MPA compared with women taking E(2)/NETA. When the dose of E(2)V was increased in the E(2)V/MPA groups, an increase in maximum bleeding intensity was observed in the group receiving 2.5 mg of MPA, but not in the group taking 5 mg of MPA. All dose combinations effectively relieved climacteric symptoms and beneficial effects on the lipid profile were seen after 6 months in all groups. Tolerability and endometrial safety were good and no cases of hyperplasia were observed. More women discontinued treatment prematurely in the E(2)/NETA group compared with either of the E(2)V/MPA groups. The overall continuation rates ranged from 70 to 86%. CONCLUSIONS These results confirm that lower dose combinations of continuous combined HRT are usually sufficient to control symptoms or avoid breakthrough bleeding. However, if higher E(2)V dose is needed for symptom control, it should be combined with the higher dose of progestin (5 mg) to avoid bleeding disturbances. Flexible treatment regimens should be available for individualized HRT.
