Mechanisms Underlying Asthma Exacerbations Prevented and Persistent with Immune-Based Therapy: A Systems Approach Phase 1
Study ID: STU 062015-051
Summary
MuPPiTS-1 is a prospective, longitudinal, nested case control study designed to identify changes in gene transcription predictive of and associated with asthma exacerbations in children ages 6 to 17 with difficult-to control, exacerbation-prone asthma. Participants will be followed prospectively for the onset of a cold and a subsequent asthma exacerbation. an internet based asthma and cold symptom diary will be accessed by participants using a hand-held device. When the participant reports development of a cold, a clinic visit will be scheduled as soon as possible (within 48 hours of cold symptom onset) to collect blood and nasal samples. a second clinic visit will occur 4-6 days from the onset of cold symptoms to obtain samples after the initial cold, but prior to the use of systemic corticosteroids. Participants will be followed for up to two colds or for a maximum of 6 months.
