Baby lung tests after bronchiolitis: clues to asthma?
NCT ID NCT00676351
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study followed 29 infants who had bronchiolitis in their first year to see if their lung function changes over time and whether that leads to asthma. Researchers measured breathing using special tests and also did allergy skin tests. However, many families dropped out, so the results are limited. The study suggests more research is needed to confirm any link.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If completed with more participants, this could help identify early signs of asthma in children who had bronchiolitis.
- What could go wrong
- The study was small (29 infants) and many dropped out, so results are incomplete. It only observed lung function and did not test any treatment.
