Conditions: Bronchiolitis Respiratory Syncytial Virus Infections
Keywords: Infant Respiratory Syncytial Virus Bronchiolitis
Allocation: NON_RANDOMIZED | Intervention model: PARALLEL
Enrollment: 59
Healthy volunteers: yes

Brief summary:
The purpose of this study is to evaluate how two different aerosol medications may improve airway function in infants with respiratory illness. We are using two different medications and comparing the difference in lung function after each medication. We will also be taking a nasal wash sample for VEGF. We will be using this in comparing how infants respond to the aerosol medications as well. We hope to help standardize medications used for infants with bronchiolitis and RSV.

Detailed description:
We hypothesize that VEGF production is higher in children with RSV infection than in children with other viral infections and normal controls. In addition, the degree of VEGF production is related to severity of airway obstruction. We also hypothesize that infants with higher VEGF levels are more likely to improve lung function following racemic epinephrine than albuterol.

Arms:
arm 1: Infants between the ages of 2-24 month, with viral lower respiratory infection defined as first episode of wheezing and shortness of breath preceded by an upper respiratory tract infection, including hospitalized infants arm 2: Healthy infants between the ages of 2-24 month arm 3: Infants 2 months to 24 months who were diagnosed with bronchiolitis received nasal wash only

Interventions: intervention 1: Inhaled primatene will be given as a breathing treatment intervention 2: Nasal Washing
Intervention descriptions: intervention 1: While the research subject is sedated an inhaled mist of primatene mist will be given to the patient. intervention 2: 1-3 mls of normal saline will be instilled into the infant's nose and then aspirated to obtain the nasal fluid, which will be analyzed for VEGF level by ELISA and viral antigens by immunoflourescence
