Menopause impacts 25 million women world wide each year, and the World Health Organization estimates 1.2 billion women will be postmenopausal by 2030. Menopause has been associated with symptoms of hot flashes, night sweats, dysphoric mood, sleep disturbance, and conditions of cardiovascular disease, depression, osteoporosis, osteoarthritis, depression, dementia, and frailty. Conventional hormone replacement therapy results in increased thrombotic events, and an increased risk of breast cancer and dementia as evidenced in large prospective clinical trials including Heart and Estrogen/Progestin Replacement Study I and the Women's Health Initiative. A possible mechanism for these adverse events is the unfavorable net effects of conjugated equine estrogens and medroxyprogesterone acetate on the hemostatic balance and inflammatory and immune factors. Physiologic sex steroid therapy with transdermal delivery for peri/postmenopausal women may offer a different risk/benefit profile, yet long-term studies of this treatment model are lacking. The objective of this study was to examine the long-term effects of compounded bioidentical transdermal sex steroid therapy including estriol, estradiol, progesterone, DHEA, and testosterone on cardiovascular biomarkers, hemostatic, inflammatory, immune signaling factors; quality-of-life measures; and health outcomes in peri/postmenopausal women within the context of a hormone restoration model of care. A prospective, cohort, closed-label study received approval from the Human Subjects Committee. Recruitment from outpatient clinics at an academic medical center and the community at large resulted in three hundred women giving signed consent. Seventy-five women who met strict inclusion/exclusion criteria were enrolled. Baseline hormone evaluation was performed along with baseline experimental measures. Following this, women received compounded transdermal bioidentical hormone therapy of BiEst (80%Estriol/20%Estradiol), and/or Progesterone for eight weeks to meet established physiologic reference ranges for the luteal phase in premenopausal women. The luteal phase hormone ratios were selected based on animal and epidemiologic studies demonstrating favorable outcomes related to traumatic, ischemic, or neuronal injury. Follow-up testing was performed at eight weeks and adjustment to hormone regimens were made including addition of androgens of DHEA and Testosterone if indicated. Experimental subjects were monitored for 36 months. Baseline, 2-month, and annual values were obtained for: blood pressure, body mass index, fasting glucose, Homeostasis Metabolic Assessment of Insulin Resistance (HOMA-IR), fasting triglycerides, total Factor VII, Factor VIII, fibrinogen, Antithrombin III, Plasminogen Activator Inhibitor1(PAL-1), C-reactive protein (CRP), Interleukin-6 (IL-6), Matrix Metalloproteinase-9 (MMP-9), Tumor Necrosis Factor-alpha (TNF), Insulin-like Growth Factor (IGF-1), and sex steroid levels. Psychosocial measures included: Greene Climacteric Scale, Visual Analog Pain Scale, Hamilton Anxiety Scale, Hamilton Depression Scale, Holmes Rahe Stress Scale, Job Strain, and Home Strain. Health outcome measures included the number of prescribed medications used, number of co-morbidities, and endometrial thickness in postmenopausal women with intact uteri. Subjects receiving compounded transdermal bioidentical hormone therapy showed significant favorable changes in: Greene Climacteric Scale scores, Hamilton Anxiety Scale, Hamilton Depression Scale, Visual Analog Pain Scale, fasting glucose, fasting triglycerides, MMP-9, C-reactive Protein, fibrinogen, Factor VII, Factor VIII, Insulin-Like Growth Factor 1, and health outcomes of co-morbidities and a number of prescribed medications. Antithrombin III levels were significantly decreased at 36 months. All other measures did not exhibit significant effects. Administration of compounded transdermal bioidentical hormone therapy in doses targeted to physiologic reference ranges administered in a daily dose significantly relieved menopausal symptoms in peri/postmenopausal women. Cardiovascular biomarkers, inflammatory factors, immune signaling factors, and health outcomes were favorably impacted, despite very high life stress, and home and work strain in study subjects. The therapy did not adversely alter the net prothrombotic potential, and there were no associated adverse events. This model of care warrants consideration as an effective and safe clinical therapy for peri/postmenopausal women especially in populations with high perceived stress and a history of stressful life events prior to, or during the menopausal transition.
更年期每年影响全球2500万女性,世界卫生组织估计,到2030年将有12亿女性进入绝经后期。更年期与潮热、盗汗、烦躁情绪、睡眠障碍以及心血管疾病、抑郁症、骨质疏松症、骨关节炎、抑郁症、痴呆症和身体虚弱等状况有关。大型前瞻性临床试验(包括心脏与雌激素/孕激素替代研究I和妇女健康倡议)表明,传统激素替代疗法会导致血栓形成事件增加,以及患乳腺癌和痴呆症的风险增加。这些不良事件的一个可能机制是结合马雌激素和醋酸甲羟孕酮对止血平衡以及炎症和免疫因子产生不利的净效应。为围绝经期/绝经后女性提供经皮给药的生理性甾体激素疗法可能具有不同的风险/获益情况,但缺乏对这种治疗模式的长期研究。本研究的目的是在激素恢复护理模式的背景下,研究复方生物等效经皮甾体激素疗法(包括雌三醇、雌二醇、孕酮、脱氢表雄酮和睾酮)对围绝经期/绝经后女性心血管生物标志物、止血、炎症、免疫信号因子、生活质量指标和健康结局的长期影响。一项前瞻性队列封闭标签研究获得了人类受试者委员会的批准。从一所学术医疗中心的门诊诊所和广大社区招募了300名签署同意书的女性。75名符合严格纳入/排除标准的女性被纳入研究。进行了基线激素评估以及基线实验测量。在此之后,女性接受了为期八周的复方经皮生物等效激素疗法,即BiEst(80%雌三醇/20%雌二醇)和/或孕酮,以达到绝经前女性黄体期既定的生理参考范围。黄体期激素比例是根据动物和流行病学研究选定的,这些研究表明与创伤性、缺血性或神经元损伤相关的良好结局。在八周时进行了随访检测,并根据需要调整激素方案,包括添加脱氢表雄酮和睾酮等雄激素。对实验对象进行了36个月的监测。获取了以下指标的基线、2个月和年度值:血压、体重指数、空腹血糖、胰岛素抵抗稳态代谢评估(HOMA-IR)、空腹甘油三酯、总因子VII、因子VIII、纤维蛋白原、抗凝血酶III、纤溶酶原激活物抑制剂1(PAI-1)、C反应蛋白(CRP)、白细胞介素-6(IL-6)、基质金属蛋白酶-9(MMP-9)、肿瘤坏死因子-α(TNF)、胰岛素样生长因子(IGF-1)以及甾体激素水平。心理社会指标包括:格林更年期量表、视觉模拟疼痛量表、汉密尔顿焦虑量表、汉密尔顿抑郁量表、霍尔姆斯-拉赫压力量表、工作压力和家庭压力。健康结局指标包括所使用的处方药数量、合并症数量以及子宫完整的绝经后女性的子宫内膜厚度。接受复方经皮生物等效激素疗法的受试者在以下方面显示出显著的有利变化:格林更年期量表评分、汉密尔顿焦虑量表、汉密尔顿抑郁量表、视觉模拟疼痛量表、空腹血糖、空腹甘油三酯、MMP-9、C反应蛋白、纤维蛋白原、因子VII、因子VIII、胰岛素样生长因子1,以及合并症和处方药数量等健康结局。抗凝血酶III水平在36个月时显著降低。所有其他指标未显示出显著影响。以每日剂量靶向生理参考范围给药的复方经皮生物等效激素疗法显著缓解了围绝经期/绝经后女性的更年期症状。尽管研究对象生活压力、家庭和工作压力都非常大,但心血管生物标志物、炎症因子、免疫信号因子和健康结局都受到了有利影响。该疗法未对血栓形成的净潜能产生不利改变,也没有相关不良事件。这种护理模式值得考虑作为围绝经期/绝经后女性的一种有效且安全的临床疗法,尤其是在那些在绝经前或绝经过渡期间感知压力高且有应激性生活事件史的人群中。
