NCT02437448

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.

Sampling MethodProbability 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:

You may qualify if:

  • Clinical symptoms consistent with IPF
  • Age 40 through 80 years
  • 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.
  • Extent of fibrotic changes (honeycombing, reticular changes) greater than extent of emphysema on HRCT scan
  • No features supporting an alternative diagnosis

You may not qualify if:

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