NCT00873873

Brief Summary

Distinct patterns of loss in pulmonary function were identified in children with mild to moderate asthma participating in a 10-year observation period during the NHLBI Childhood Asthma Management Program. This loss in pulmonary function is likely related to ongoing inflammation unresponsive to current therapy. This study will measure indicators of airway inflammation which are associated with structural and physiologic changes in the lung and provide insight into mechanisms of asthma progression in adolescence and early adulthood.

Sampling MethodNon-Probability Sample
Study Population

Participants enrolled in CAMPCS/3 from various CAMP sites will be invited to participate in this study.

You may qualify if:

  • Must be enrolled in the CAMPCS/3 study; individuals enrolled in this study will represent four different patterns of asthma progression, as defined by forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC) levels

You may not qualify if:

  • Unwilling to comply with study procedures
  • Physical state does not allow the study procedures to be performed (e.g., low pulmonary function for induced sputum, pregnancy for computerized tomography \[CT\] scan)

Contact the study team to confirm eligibility.

Limitations and Caveats

We had planned to extend invitations to the remaining 55 participants in a streamlined version of this protocol after analyzing the preliminary data and an additional cycle of CAMP was funded in 2007.
