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.

Secondary
| 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. | Single time point |
