About this study

Official title: Department of Critical Care Medicine, Taichung Veterans General Hospital

A prospective observational study. Enrolled participants admitted to ICU due to pneumonia and respiratory failure need mechanical ventilator support. Investigators collected the residual specimens, such as sputum from endotrachea aspiration, bronchoalveolar lavage fluid in those participants as the usual care in the ICU. Those residual samples were sent to extract RNA and sequence by using high-throughput sequencing (next-generation sequencing) method.

Investigators will compared the microbiome feature between lower respiratory tract and stool specimens in those participants diagnosed as pneumonia with respiratory failure.

Being tested
16s RNA sequence of sputum, bronchoalveolar lavage fluid (options), stool
Keywords
Microbiota, Respiratory Failure, Pneumonia, Lower Respiratory Tract Infection

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • 16s RNA sequence of sputum, bronchoalveolar lavage fluid (options), stoolDiagnostic test

    We will check the microbiome in lower respiratory samples (sputum and bronchoalveolar lavage fluid) and stool by using 16S RNA sequencing

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The dynamics of the airway bacterial microbiome in the lower respiratory tract specimens in the setting of pneumonia accompanied by respiratory failure at the onset of, and day 3 and day 7 (or before extubation)

    Uses high-throughput sequencing (next-generation sequencing) to sequence the 16S rRNA sequence of bacteria in residual samples

    Measured: Compared the dynamic change of mirobiome at the baseline (onset of respiratory failure within 48 hours)m day 3 and day 7

Secondary outcomes (2)
  1. The dynamics of the gut bacterial microbiome in the stool specimens in the setting of pneumonia accompanied by respiratory failure at the onset of, and day 3 and day 7 (or before extubation)

    uses high-throughput sequencing (next-generation sequencing) to sequence the 16S

    Measured: Compared the dynamic change of mirobiome at the baseline (onset of respiratory failure within 48 hours)m day 3 and day 7

  2. The association of the microbiome between lower respiratory tracts and stool specimens in pneumonic patient with respiratory failure

    Uses high-throughput sequencing (next-generation sequencing) to sequence the 16S

    Measured: Compared the association of mirobiome at the baseline (onset of respiratory failure within 48 hours)m day 3 and day 7

Questions about this trial

What is this clinical trial studying?

An observational study of Microbiota and Pneumonia, Bacterial, run by Taichung Veterans General Hospital at 1 site in Taiwan.

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 3 inclusion and 3 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 16 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. 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?

The dynamics of the airway bacterial microbiome in the lower respiratory tract specimens in the setting of pneumonia accompanied by respiratory failure at the onset of, and day 3 and day 7 (or before extubation) (time frame: Compared the dynamic change of mirobiome at the baseline (onset of respiratory failure within 48 hours)m day 3 and day 7). 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 16 Sep 2019.
