Markers of Airway Inflammation in BAL Fluid From Children With Asthma

October 19, 2020 updated by: National Jewish Health

Prospective Analysis of Markers of Airway Inflammation and Remodeling in Bronchoalveolar Lavage Fluid From Children With Asthma.

The study compares the biochemical markers in bronchoalveolar lavage samples from asthmatic children to those markers found in non-asthmatic children with other respiratory diseases. The investigators hypothesize that certain markers will be associated specifically with asthma.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Time Frame
The measurement of levels of lipopolysaccharides [LPS], which mediates airway inflammation, in bronchoalveolar lavage [BAL] fluid from children with asthma and comparison to LPS levels in children with non-asthma respiratory diseases
Time Frame: Single time point
Single time point

Secondary Outcome Measures

Outcome Measure
Time Frame
Characterization of the inflammatory cytokine and chemokine profiles in bronchoalveolar lavage [BAL] fluid in children with asthma and comparison to the profile for children with non-asthma respiratory diseases.
Time Frame: Single time point
