Brief Summary:
The aim of the study is to answer the question whether a disease specific profile of breath in patients with idiopathic lung fibrosis can be detected by an untargeted metabolomic study using exhaled breath analysis by mass spectrometry.

Condition or disease Intervention/treatment
Idiopathic Lung Fibrosis Idiopathic Pulmonary Fibrosis Other: No intervention

Study Type : Observational
Estimated Enrollment : 50 participants
Observational Model: Case-Control
Time Perspective: Prospective
Official Title: Exhaled Breath Analysis by Secondary Electrospray Ionization - Mass Spectrometry (SESI-MS) in Patients With Pulmonary Fibrosis
Study Start Date : June 2015
Estimated Primary Completion Date : October 2020
Estimated Study Completion Date : March 2021

Group/Cohort Intervention/treatment
Idiopathic lung fibrosis
20 IPF patients
Other: No intervention
20 subjects with no apparent lung disease and normal lung function testing. Matched for gender, age and smoking history.
Other: No intervention

Primary Outcome Measures :
  1. IPF-specific mass spectrometric profile of volatile organic compounds of exhaled breath analysis (markers of IPF in exhaled breath) [ Time Frame: 1 day ]

Biospecimen Retention:   None Retained
Exhaled breath

Accepts Healthy Volunteers:   Yes
Sampling Method:   Probability Sample
Study Population
Confirmed diagnosis of idiopathic pulmonary fibrosis based on clinical, radiologic and/or pathologic data without evidence or suspicion of an alternative diagnosis that may contribute to their interstitial lung disease. Patients must fulfill all of the following criteria:

Inclusion Criteria:

  1. Clinical symptoms consistent with IPF
  2. Age 40 through 80 years
  3. Diagnosis of UIP or IPF by HRCT and surgical lung biopsy as outlined in table 1. Only patients fulfilling the category "YES" will be included in the study.
  4. Extent of fibrotic changes (honeycombing, reticular changes) greater than extent of emphysema on HRCT scan
  5. No features supporting an alternative diagnosis

Exclusion Criteria:

  1. Acute exacerbation within the last 6 weeks.
  2. Any relevant lung disease other than pulmonary fibrosis.
  3. Acute inflammatory disease (e.g. common cold) within the last 6 weeks.
  4. Acute or chronic hepatic disease.
  5. Renal failure or renal replacement therapy.
