The purpose of this study is to determine Fractional exhaled Nitric-Oxide (FeNO)levels and blood cytokines during acute bronchiolitis, and to seek for correlation between these markers and future development of asthma.

Acute Bronchiolitis

Study Type: Observational [Patient Registry]
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Target Follow-Up Duration: 7 Years
Official Title: FeNO and Cytokines in RSV and Non RSV Bronchiolitis in Relation to Future Asthma

Further study details as provided by Tel-Aviv Sourasky Medical Center:

Primary Outcome Measures:
  • Physician diagnosed asthma [ Time Frame: At the age of 4 years ]
    Modification of The International Study of Asthma and Allergies in Childhood (ISAAC) questionnaires

Secondary Outcome Measures:
