Abstract

This review describes the evolving role of oral hormone therapy (HT) for treating menopausal symptoms and preventing osteoporosis, focusing on conjugated estrogens/bazedoxifene (CE/BZA). Estrogens alleviate hot flushes and prevent bone loss associated with menopause. In nonhysterectomized women, a progestin should be added to estrogens to reduce the risk of endometrial cancer. Use of HT declined since the Women's Health Initiative (WHI) studies showed that HT does not prevent coronary heart disease (CHD) and that conjugated estrogens/medroxyprogesterone acetate increased the risk of invasive breast cancer after nearly 5 years of use. However, re-analyses of the WHI data suggest that some risks (eg, CHD, all-cause mortality) may be reduced when HT is initiated in women <60 years of age and <10 years since menopause, compared with later. CE/BZA is the first menopausal HT without a progestogen for nonhysterectomized women. Instead, BZA, a selective estrogen receptor modulator, in combination with CE, protects against estrogenic effects on uterine and breast tissue. Data from 5 large, randomized clinical trials show that CE/BZA reduces hot flush frequency/severity, prevents bone loss, reduces bone turnover, improves the vaginal maturation index and ease of lubrication, and improves some measures of sleep and menopause-specific quality of life. In studies of up to 2 years, there was no increase in endometrial hyperplasia, vaginal bleeding, breast density, or breast pain/tenderness compared with placebo. Venous thromboembolism and stroke are risks of all estrogen-based therapies. The choice of HT should be individualized, with consideration of the risk/benefit profile and tolerability of therapy, as well as patient preferences.

摘要

本综述描述了口服激素疗法(HT)在治疗更年期症状和预防骨质疏松症方面不断演变的作用,重点关注共轭雌激素/巴多昔芬(CE/BZA)。雌激素可缓解潮热,并预防与更年期相关的骨质流失。对于未行子宫切除术的女性,应在雌激素中添加孕激素以降低子宫内膜癌风险。自妇女健康倡议(WHI)研究表明HT不能预防冠心病(CHD),且共轭雌激素/醋酸甲羟孕酮在使用近5年后会增加浸润性乳腺癌风险以来,HT的使用量有所下降。然而,对WHI数据的重新分析表明,与绝经10年后开始使用HT相比,在60岁以下且绝经不到10年的女性中开始使用HT,某些风险(如CHD、全因死亡率)可能会降低。CE/BZA是首款用于未行子宫切除术女性的不含孕激素的更年期HT。相反,选择性雌激素受体调节剂巴多昔芬(BZA)与CE联合使用,可预防雌激素对子宫和乳腺组织的影响。5项大型随机临床试验的数据表明,CE/BZA可降低潮热频率/严重程度,预防骨质流失,减少骨转换,改善阴道成熟指数和润滑程度,并改善一些睡眠指标和更年期特定生活质量指标。在长达2年的研究中,与安慰剂相比,子宫内膜增生、阴道出血乳腺密度或乳腺疼痛/压痛均未增加。静脉血栓栓塞和中风是所有基于雌激素疗法的风险。HT的选择应个体化,需考虑治疗的风险/获益情况、耐受性以及患者偏好。
