Brief Summary:
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.

1 Asthma subjects
Children with asthma undergoing clinically indicated bronchoscopy at National Jewish Health.
2 Non-asthma subjects
Children with other respiratory diseases than asthma undergoing clinically indicated bronchoscopy at National Jewish Health.

Primary Outcome Measures :
  1. 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 ]

Secondary Outcome Measures :
  1. 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 ]
