Idiopathic pulmonary fibrosis (IPF) is a progressive, fatal, fibrotic disorder of the lung.
The estimated prevalence is 30-80/100,000 in the United States with incidence estimates
clearly rising. A major challenge in the care of patients with IPF is determining prognosis.
The natural history of IPF is usually one of inexorable decline in lung function, ultimately
resulting in death from respiratory failure. However, longitudinal physiologic decline in IPF
is heterogeneous and difficult to predict in individual patients. While some patients with
IPF may remain stable for years, in others the disease may progress rapidly over a relatively
short time. We hypothesize that peripheral blood biomarkers based on extracellular matrix and
matrix-modifying molecules will improve prognostication in patients with IPF.

Inclusion Criteria:
1. Age 35-80 years, inclusive
2. Diagnosis of IPF by HRCT or surgical lung biopsy

Exclusion Criteria:
1. AE-IPF during the prior year
2. Environmental exposure (occupational, drug, etc.) felt to be the etiology of the
interstitial disease.
3. Diagnosis of collagen-vascular conditions according to published American College of
Rheumatology criteria.
4. Significant airway obstruction (FEV1/FVC ratio < 0.60) or bronchodilator response,
defined as a change in FEV1 ≥ 12% and absolute change > 200 mL OR change in FVC ≥ 12%
and absolute change > 200 mL at baseline
5. Partial pressure of arterial oxygen (PaO2) < 55 mm Hg
6. Evidence of active infection
7. Listed for lung transplantation
8. Myocardial infarction, coronary artery bypass, or angioplasty within 6 months
9. Unstable angina pectoris or congestive heart failure requiring hospitalization or
deteriorating within 6 months
10. Uncontrolled arrhythmia or hypertension
11. Known HIV, hepatitis C, cirrhosis, or chronic active hepatitis
12. Active substance and/or alcohol abuse
13. If you are pregnant or breastfeeding
14. Any condition other than IPF that is likely to result in your death within the next
year
15. Any condition that, in the judgment of the PI, might cause participation in the study
to be detrimental to you or that the PI deems makes you a poor candidate
