Advancing Prevention of Pulmonary Fibrosis

This study plans to learn more about pulmonary fibrosis and how it develops. We want to determine if the disease can be detected early, before the lung is permanently scarred.

This study will enroll participants who are not currently diagnosed with pulmonary fibrosis, but who have family members with pulmonary fibrosis. Because there is an increased risk within affected families, this cohort will allow us to learn how pulmonary fibrosis develops, and how the lungs change over time.

Treatment and study plan

Sample collection

Other

Blood, Urine, Nail, Hair, Saliva, optional Stool

questionnaires

Other

SF-36, Food Frequency, Pulmonary Fibrosis Study questionnaire, COVID questionnaire

High resolution CT scan of the chest

Radiation

Upon enrollment, all participants will undergo single prone volumetric thoracic chest CT scan. This will be performed at full inspiration using a 64-slice CT scanner.

Pulmonary Function Test

Diagnostic Test

All recruited participants will undergo a pre-bronchodilator spirometry test and a lung diffusion capacity test, both in accordance with ATS guidelines. Exercise capacity (maximum physical exertion) will be assessed by performing a 6-minute walk test, also according to ATS guidelines.

Primary outcomes

  1. Screen all subjects for early Idiopathic Pulmonary Fibrosis (IPF) with High Resolution CT Scan of the Chest

    Time frame: Baseline

    All subjects will be screened with a high resolution CT scan to identify early signs of lung fibrosis. CT scans will be evaluated by study radiologists.
