Brief Summary
The mission of the SARP is to improve the understanding of severe asthma through integrated study of its clinical and biological features and to evaluate their changes over time. The ultimate goal of these efforts is to promote better treatments for severe asthma.

Outcome Measures
Primary Outcomes (1)
Pulmonary function test results
Pulmonary function test results include forced expiratory volume in one second (FEV1) and forced vital capacity (FVC).
36 months after enrollment
Secondary Outcomes (1)
Frequency of severe asthma exacerbations
36 months after enrollment
Study Arms (2)
Asthmatics
Subjects with active asthma.
Healthy Controls
Subjects without any known pulmonary disease.
Eligibility Criteria
The target study population will is 80% adults (age 18 and older) and 20% children age 6-17 years, 50% females, and 30% minorities. Approximately 100 Healthy Control patients, matching the demographic characteristics of the asthma patients, will also be recruited in order to generate reference data for biospecimens collected from asthmatic patients.
You may qualify if:
- Physician diagnosis of asthma,
- Age 6 years and older
- Evidence of historical reversibility, including either:
- FEV1 bronchodilator reversibility ≥ 12%, or
- Airway hyperresponsiveness reflected by a methacholine PC20 ≤16 mg/mL.
You may not qualify if:
- Pregnancy during the characterization phase,
- Current smoking,
- Smoking history \> 10 pack years if ≥30 years of age, or smoking history \> 5 pack years if \<30 years of age (Note: if a subject has a smoking history, no smoking within the past year),
- Other chronic pulmonary disorders associated with asthma-like symptoms, including (but not limited to) cystic fibrosis, chronic obstructive pulmonary disease, chronic bronchitis, vocal cord dysfunction (that is the sole cause of respiratory symptoms and at the PI's discretion), severe scoliosis or chest wall deformities that affect lung function, or congenital disorders of the lungs or airways,
- History of premature birth before 35 weeks gestation,
- Unwillingness to receive an intramuscular triamcinolone acetonide injection,
- Evidence that the participant or family may be unreliable or poorly adherent to their asthma treatment or study procedures,
- Planning to relocate from the clinical center area before study completion,
- Any other criteria that place the subject at unnecessary risk according to the judgment of the Principal Investigator and/or attending physician(s) of record, or
- Currently participating in an investigational drug trial for asthma therapies.
- Healthy Controls:
- History of chronic diseases that affect the lungs,
- A history suggestive of allergic rhinitis, eczema or chronic sinusitis,
- An improvement in FEV1 of more than 12% following 4 puffs of albuterol,
- Smoking history \> 10 pack years if ≥30 years of age, or smoking history \> 5 pack years if \<30 years of age, or any smoking within the past year,
- +3 more criteria
