Is this trial a fit for you?

Likely a good fit

Ideal candidates include patients undergoing diagnostic bronchoscopy for clinical reasons who consent to participate in the study.

Probably not a fit

Patients who do not wish to participate in the proteomic analysis or chart review will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study analyzes bronchoalveolar lavage (BAL) fluid from patients with pneumonia to identify protein and peptide patterns associated with different types of pulmonary diseases. By using advanced proteomic techniques, the research aims to discover biomarkers that can help determine the causes of lung inflammation and infection. Patients undergoing bronchoscopy at the NIH Clinical Center will provide BAL samples, which will be analyzed to improve understanding of the host response to pneumonia and potentially guide treatment options.

Why it matters

Potential benefit: If successful, this study could lead to the identification of specific biomarkers that improve diagnosis and treatment of pneumonia.

How similar studies have gone: While similar studies have explored biomarkers in pneumonia, this approach using advanced proteomic analysis is relatively novel.

Show full inclusion / exclusion criteria
* INCLUSION CRITERIA:
* All eligible patients undergoing diagnostic bronchoscopy who provide consent for proteomic analysis of BAL fluid supernatant and chart review of patient characteristics will be included in this study.
* A parent/guardian may provide consent for a child age 17 or under and a Legally Authorized Representative (LAR) may provide consent for adults unable to consent.

EXCLUSION CRITERIA:

Patients undergoing bronchoscopy but not wanting to participate with either the chart review or the proteomic analysis of BAL fluid supernatant will be excluded.
