About this trial
This is a one-year longitudinal, observational study of 250 urban children and adolescents with asthma and 60 without asthma, ages 6-17 years old.
Participants with asthma will require daily controller therapy with inhaled corticosteroids ICS (at least Step 2 therapy). Those without asthma cannot have used asthma medications in the year prior to enrollment and cannot demonstrate bronchodilator reversibility at baseline. Phenotypic characteristics will be established at baseline, and the participants will be seen at scheduled visits over 12 months. Each participant will be asked to monitor and self-report cold symptoms and will be asked to complete up to three cold visits

Trial groups
Trial outcomes
Primary outcomes
Asthma disease activity measured by the number of exacerbations during the 12-month observation period
Secondary outcomes
Childhood Asthma Severity Index (CASI)
measured on a scale from 0 to 20 with smaller scores indicate a better outcome.
Modified Rhinitis Symptom Utility Index (MRSUI)
measured by assessing the frequency and severity (degree of bothering: not bothered, somewhat bothered, bothered a lot) of the participant's (1) stuffy or blocked nose, (2) runny nose, (3) sneezing, (4) itchy, watery eyes, and (5) itchy nose or throat over the preceding 14-day period
Wisconsin Upper Respiratory Symptom Survey for Kids (WURSS-K)
measured on a scale from 0 to 42 with higher scores indicating a worse outcome (high symptoms and high functional impairment)
Quality of life measured by the pediatric patient-reported (ages 8-17) or proxy-reported (ages 6-7) Patient-Reported Outcomes Measurement Information System (PROMIS) Asthma Impact Short Forms
The outcome measure is a score on a scale from 8 - 40 with higher scores indicating a worse outcome (more severe asthma symptoms).
