项目摘要

DESCRIPTION (provided by applicant): Exogenous estrogens, a heterogeneous group of estrogenic compounds that includes conjugated equine estrogen (CEE), estradiol (E2), and esterified estrogen (EE), are a controversial and potentially harmful pharmaceutical therapy that nonetheless continues to be used by peri- and post-menopausal women. Venous thrombosis (VT) may be one of the most serious side-effect of short-term estrogen use. It has been demonstrated that CEE, historically the most commonly prescribed estrogen, and EE, have differential effects on VT risk. Estradiol is the second most commonly prescribed oral estrogen in the US and its association with VT risk is not known. This application is a competing renewal to support novel work investigating estrogens and pharmacogenetic risk factors for VT in peri- and post-menopausal women in a population-based, case-control study at Group Health. The recent change in the preferred formulary estrogen at Group Health to E2 provides us with a unique opportunity to characterize the VT risk associated with this commonly used oral estrogen. As our primary aim in this renewal, we hypothesize that VT risk is greater in users of oral E2 compared with non-users of estrogen and, moreover, VT risk is greater in oral E2 users compared with oral CEE users or compared with oral EE users. As a secondary aim, we will use laboratory-based measures to characterize the clotting propensity of oral E2, oral CEE, and non-users of estrogen among healthy subjects. An additional aim is to determine which newly identified genetic risks of thrombosis from the growing literature are modified by estrogen use. The setting for the study is Group Health, a large integrated healthcare organization in Washington State. The study population will include peri- and post-menopausal Group Health members 30 to 89 years of age who experienced an incident VT, either deep vein thrombosis or fatal or non-fatal pulmonary embolism. This application will support the identification and the abstraction of medical record data VT cases and their matched controls that occur through 2013. Blood will be collected and DNA abstracted from those who consent. Data on the safety of oral estrogen products are limited and hinder women and their physicians from making evidence-based decisions when choosing an estrogen product to treat vasomotor symptoms of menopause. This competing renewal is designed to expand research using this unique and valuable resource that has already produced important epidemiologic information and will likely provide high-quality data to begin to address important public health questions of women's health. PUBLIC HEALTH RELEVANCE: Data on the safety of oral estrogen products are limited and hinder women and their physicians from making evidence-based decisions when choosing an estrogen product to treat vasomotor symptoms of menopause. Venous thrombosis may be the most serious side-effect of short-term estrogen use yet virtually nothing is known about the risks of oral estradiol, the second most commonly used estrogen. We propose an extension of our population-based, case-control study in post-menopausal women to examine risks of venous thrombosis associated with oral estradiol and other estrogens.
描述(由申请人提供):外源性雌激素是一组异质性雌激素化合物,包括结合马雌激素(CEE)、雌二醇(E2)和酯化雌激素(EE),是一种有争议且可能有害的药物治疗,但仍继续被绝经期和绝经后妇女使用。静脉血栓形成(VT)可能是短期使用雌激素最严重的副作用之一。它已被证明,CEE,历史上最常用的处方雌激素,和EE,对VT风险有不同的影响。雌激素是美国第二常用的口服雌激素,其与VT风险的关系尚不清楚。该申请是一项竞争性更新,旨在支持在Group Health进行的一项基于人群的病例对照研究中,研究绝经后和绝经后妇女中VT的雌激素和药物遗传学风险因素的新工作。最近在集团健康的首选处方雌激素E2的变化为我们提供了一个独特的机会,以表征与这种常用的口服雌激素相关的VT风险。作为本次更新的主要目的,我们假设口服E2使用者的VT风险高于非雌激素使用者,此外,口服E2使用者的VT风险高于口服CEE使用者或口服EE使用者。作为次要目的,我们将使用基于实验室的措施来表征健康受试者中口服E2、口服CEE和非雌激素使用者的凝血倾向。另一个目的是确定从越来越多的文献中新发现的血栓形成的遗传风险被雌激素的使用所改变。这项研究的背景是集团健康,一个大型综合医疗保健组织在华盛顿州。研究人群将包括30 - 89岁的绝经期和绝经后健康组成员,他们发生了VT事件,无论是深静脉血栓形成还是致死性或非致死性肺栓塞。该应用程序将支持识别和提取2013年之前发生的VT病例及其匹配控制的医疗记录数据。将从同意的人身上采集血液和DNA。关于口服雌激素产品安全性的数据是有限的,这阻碍了妇女和她们的医生在选择雌激素产品治疗更年期血管痉挛症状时做出基于证据的决定。这一竞争性更新旨在利用这一独特而宝贵的资源扩大研究,该资源已经产生了重要的流行病学信息,并可能提供高质量的数据,以开始解决妇女健康的重要公共卫生问题。公共卫生相关性:关于口服雌激素产品安全性的数据是有限的,这阻碍了妇女和她们的医生在选择雌激素产品治疗更年期血管痉挛症状时做出基于证据的决定。静脉血栓形成可能是短期使用雌激素最严重的副作用,但实际上对口服雌二醇(第二种最常用的雌激素)的风险一无所知。我们建议扩展我们在绝经后妇女中进行的以人群为基础的病例对照研究,以检查与口服雌二醇和其他雌激素相关的静脉血栓形成风险。
