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.


Study Type: Observational
Study Design: Observational Model: Case Control
Time Perspective: Prospective

Further study details as provided by National Jewish Health:

Primary Outcome Measures:
  • 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 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • 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 ] [ Designated as safety issue: No ]

Estimated Enrollment: 40
