项目摘要
Project Abstract
The interstitial lung diseases (ILDs) are a family of closely related lung conditions characterized by alveolar
inflammation, injury, and/or fibrosis not due to infection or neoplasia. Idiopathic pulmonary fibrosis (IPF), a
fibrotic ILD affects nearly 1 in 200 older adults and carries a poor prognosis. Therapeutic options are limited,
and to date no study has tested interventions that prevent the development of a fibrotic ILD. We are conducting
studies that are preparatory to and requisite for future clinical trials of preventative IPF and ILD interventions.
To move toward this goal, in the previous award period, we established the construct validity of a novel
quantitative computed tomographic (CT)-based measure, termed high attenuation areas (HAAs), as an
imaging biomarker of early, mild alveolar inflammation, injury, and fibrosis in a large cohort of community
dwelling adults enrolled in the Multi-Ethnic Study of Atherosclerosis (MESA), an ongoing NHLBI-funded
prospective cohort study of 6,814 adults age 45 and older at enrollment in 2000 through 2002. These data
strongly support HAA as a novel and relevant quantitative biomarker of the earliest biological changes in the
lung parenchyma that later lead to ILD, yet additional work is required to move these findings into future clinical
trials and into the clinic. In the current application, we propose to examine the pulmonary histopathology and
biology of HAA in first-degree relatives of adults with clinically diagnosed ILD. To achieve these goals, we will
initiate the Families At-Risk for ILD (FAR-ILD) study, a prospective study of adults with ILD and their first-
degree relatives designed to identify adults with subclinical ILD and those at-risk for incident ILD. We will also
use the MESA cohort to develop a clinical prediction model for incident radiologic ILD. Our study will provide
strong evidence that will inform future studies of preventative interventions for adults at high risk of ILD. Our
results will also help identify potential targetable pathways for prevention in at-risk adults and inform future
phase 2 trial of a preventative intervention, such as pirfenidone, nintedanib, or N-acetylcysteine (which may be
effective in subsets of individuals), or perhaps by targeting a pathway identified through our study of the
biology of early subclinical ILD.
项目摘要
间质性肺疾病(ILD)是一组密切相关的肺部疾病,其特征在于肺泡上皮细胞(肺泡上皮细胞)的过度增殖。
特发性肺纤维化(IPF)是指非感染或瘤形成引起的炎症、损伤和/或纤维化。
纤维化ILD影响近1/200的老年人,预后不良。治疗选择有限,
到目前为止,还没有研究测试预防纤维化ILD发展的干预措施。
为未来预防性IPF和ILD干预措施的临床试验做准备和必要的研究。
为了实现这一目标,在上一个奖项期间,我们建立了小说的结构效度
基于定量计算机断层扫描(CT)的测量,称为高衰减区域(哈斯),作为
一个大型社区队列中早期轻度肺泡炎症、损伤和纤维化的影像学生物标志物
一个正在进行的NHLBI资助的多种族动脉粥样硬化研究(梅萨)的居住成年人
2000年至2002年,对6,814名年龄在45岁及以上的成年人进行了前瞻性队列研究。
强烈支持HAA作为一种新的和相关的定量生物标志物的最早的生物学变化,
肺实质,后来导致ILD,但需要额外的工作,以将这些发现转移到未来的临床
在本申请中,我们提出检查肺组织病理学,
临床诊断为ILD的成人一级亲属中HAA的生物学。为了实现这些目标,我们将
启动ILD高危家庭(FAR-ILD)研究,这是一项针对ILD成人患者及其首次发病的前瞻性研究。
旨在识别亚临床ILD成人患者和有ILD事件风险的患者。我们还将
使用梅萨队列来开发偶发放射学ILD的临床预测模型。我们的研究将提供
强有力的证据,将为未来的ILD高危成人预防性干预研究提供信息。
研究结果还将有助于确定潜在的有针对性的预防途径,
预防性干预的II期试验,如吡非尼酮、尼达尼布或N-乙酰半胱氨酸(可能
在个体的子集中有效),或者也许通过靶向通过我们的研究确定的途径,
早期亚临床ILD的生物学。
