Brief Summary
The mission of 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.

Study Arms (3)
Mild-to-Moderate Asthma
Those with mild-to-moderate persistent asthma as defined by the NAEPP EPR-3 guidelines.
Severe Asthma
Major Criteria: (1 required) 1. Treatment with oral corticosteroids for at least 6 of the previous 12 months 2. Treatment with high-dose inhaled corticosteroids (ICS) for at least 10 of the previous 12 months Minor Criteria: (2 required) 1. Daily treatment with an asthma controller medication in addition to ICS, or 2. Asthma symptoms requiring short-acting bronchodilator use on a daily or near daily basis, or 3. Persistent airway obstruction with baseline FEV1 \<80% predicted, or 4. ≥ 1 urgent visits for asthma in the previous 12 months, or 5. ≥ 3 systemic corticosteroid bursts in the previous 12 months, or 6. Prompt deterioration with a reduction in oral or inhaled corticosteroid dose, or 7. A near-fatal asthma event (i.e., intubation) in the past
Healthy Controls
Those without asthma or other chronic lung disease.
Eligibility Criteria
A diverse sample of subjects with asthma is needed to gain better understanding of asthma and its endotypes. SARP will therefore enroll subjects 6 years and older with a physician diagnosis of asthma. The target recruitment goal for each center is 75% adults (age 18 and older) and 25% children age 6-17 years. Within the pediatric age group, an attempt will be made to enroll equal numbers of children 6-11 and 12-17 years of age. Similarly, an attempt will be made to enroll at least 50% females and 30% minorities.
You may qualify if:
- 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,
- 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.
- 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.
