英文摘要
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.
