DESCRIPTION (provided by applicant): Thirty-nine percent of reproductive age women have used a non-steroidal anti-inflammatory drug (NSAID) in the past week, and NSAIDs are the most frequent medication exposure in the first trimester of pregnancy. The safety of NSAID use in early pregnancy is uncertain. Our objective is to examine prospectively the association of NSAID use with spontaneous abortion. We propose to enroll women who are planning a pregnancy and obtain daily diaries of medication use, symptoms (indications) and other key confounders during the period while participants are attempting to conceive. Among the first 1,200 women who become pregnant, we will continue to collect daily diary information through the 12th week of pregnancy, obtain an early pregnancy ultrasound in the sixth week, and conduct an extensive computer assisted telephone interview at 13 weeks. Birth outcomes will be documented for all pregnancies and karyotyping will be done on all losses where a tissue specimen is available. These methods will allow us to answer our primary research questions: (1) Is NSAID use independently associated with increased risk of spontaneous abortion? (2) Does the association of NSAIDs with spontaneous abortion depend on cumulative dose, regular versus episodic use, and/or exposure during critical developmental windows? and these secondary questions: (3) Are common indications for NSAID use independently associated with spontaneous abortion? (4) Does developmental stage attained prior to spontaneous abortion differ between exposed and unexposed pregnancies? The primary tools for the proposed study are already in place including successful approaches to community-based recruitment prior to pregnancy, ultrasound forms and protocols, computer assisted telephone interviews, data management and quality control systems and experienced staff. Costly piloting and implementation phases have been completed. In short, we are fully prepared to efficiently address pressing questions about NSAID exposure in early pregnancy by conducting a large-scale, fully-prospective cohort study. If NSAID use has an adverse effect on early pregnancy outcomes, the public health impact would be substantial. For example, if NSAID exposure increases relative risk by 50 per cent, and 19 per cent of women use NSAIDs during the first trimester of pregnancy (a conservative estimate based on retrospective data), then over 80,000 spontaneous abortions could be attributed to NSAIDs each year in the United States.

描述(申请人提供)：39%的育龄妇女在过去一周内使用过非类固醇抗炎药(NSAID)，非类固醇抗炎药是怀孕前三个月最频繁的药物暴露。在怀孕早期使用非甾体抗炎药的安全性尚不确定。我们的目标是前瞻性地研究非甾体抗炎药的使用与自然流产的关系。我们建议招募计划怀孕的女性，并在参与者试图怀孕期间获得每日用药日记、症状(适应症)和其他关键混杂因素。在最初的1200名怀孕妇女中，我们将继续收集怀孕第12周的每日日记信息，在第6周进行早孕超声波检查，并在第13周进行广泛的计算机辅助电话采访。所有妊娠的出生结局都将被记录下来，如果有组织样本，将对所有丢失的胎儿进行核型分析。这些方法将使我们能够回答我们的主要研究问题：(1)非甾体类抗炎药的使用是否与自然流产风险的增加独立相关？(2)非类固醇抗炎药与自然流产的相关性是否取决于累积剂量、定期与间歇性使用和/或关键发育窗口期间的暴露？还有这些次要问题：(3)非甾体类抗炎药的常见适应症是否与自然流产独立相关？(4)在自然流产之前达到的发育阶段在暴露和未暴露的妊娠之间是否有区别？拟议研究的主要工具已经到位，包括孕前社区招聘的成功办法、超声波表格和方案、计算机辅助电话访谈、数据管理和质量控制系统以及经验丰富的工作人员。耗资巨大的试点和实施阶段已经完成。简而言之，我们已经做好充分准备，通过进行一项大规模的、完全前瞻性的队列研究，有效地解决有关怀孕早期非类固醇抗炎药暴露的紧迫问题。如果非甾体抗炎药的使用对早孕结局有不利影响，公共卫生影响将是巨大的。例如，如果接触非类固醇抗炎药使相对风险增加50%，19%的妇女在怀孕前三个月使用非类固醇抗炎药(基于回顾数据的保守估计)，那么在美国，每年有80,000多例自然流产可归因于非类固醇抗炎药。
