About this study

Official title: Detection of Mycobacteria in Lungs and Culture Using an Ultra-fast Gas Chromatograph

The Pulmonary Colonization Test is a non-invasive breath test for markers of lower respiratory tract infection, which may predict the probability of mycobacterial organisms in the lower respiratory tract. It consists of:

  • A breath collection apparatus for collection of volatile organic compounds in breath onto a sorbent trap and Tedlar bag, as well as for the collection of a separate sample of room air.
  • Analysis of the volatile organic compounds in breath and room air by short acoustic wave/gas chromatography.
  • Interpretation of the volatile organic compounds with a proprietary algorithm in order to predict the probability of lower respiratory tract colonization and infection.
  • Analysis of the volatile organic compounds in sputum culture by short acoustic wave/gas chromatography.

This study will test the hypothesis that the investigators can identify the presence of mycobacteria in an individual by sampling the breath of patients with active tuberculosis and by sampling "head space" above culture media of sputum provided. This study will test the hypotheses:

  • that the investigators can identify positive cultures for mycobacterium tuberculosis through sampling of the headspace above the cultures prior to standard laboratory culture identification
  • that the investigators can identify control of tuberculosis by sampling exhaled breath

Questions about this trial

What is this clinical trial studying?

An observational study of Pulmonary Tuberculosis, run by Landon Pediatric Foundation at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 Aug 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Identification of tuberculosis from bacterial plates (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Aug 2014.
