After 6 weeks, patients will once again undergo bronchoscopy with BAL/biopsies. Cytokine protein arrays will be repeated. Comparisons will then be made intra-group before and after therapy. Additional comparisons of inflammation and bronchial hyper-responsiveness will be made between groups. Randomization will allow the investigators to control for any changes in cytokine patterns due to seasonal affect (if both groups reduce the concentration of Interleukin-5 in a similar pattern, this is more likely seasonal than due to acid suppression).
