Wheezing on admission: a marker for bronchiolitis severity and asthma development
摘要
Supervised clustering of bronchiolitis patients, according to their clinical characteristics at hospital admission, helps predict short-term hospital outcomes and the risk of developing childhood respiratory illness. Thus, we evaluated the use of wheezing status for stratifying bronchiolitis patients.
MethodsA prospective cohort study was conducted involving 668 previously healthy, full-term Chilean infants ( < 2 years old) hospitalized with bronchiolitis. Patients categorized based on their wheezing status at hospital admission were monitored during hospitalization and followed for 4 years after discharge.
ResultsWheezing children presented a more severe illness requiring more oxygen during their hospital stay. Upon discharge, they were more likely to develop preschool wheezing at 12 months and asthma at 4 years of age. Among the non-wheezing, those with RSV had more severe disease. Risk factors exclusively associated with persistent asthma development for the wheezing were clinical bacterial coinfection, parental asthma history, and having had a severe bronchiolitis episode. Risk factors exclusive for non-wheezing were maternal smoking during pregnancy and severe retractions.
ConclusionBronchiolitis patients can be categorized based on their wheezing status at hospital admission, helping predict short-term clinical outcomes and identify infants at risk of developing severe short- and long-term respiratory illnesses.
ImpactStratifying viral bronchiolitis patients using a simple bedside strategy based on their wheezing status at hospitalization can help improve individual-based clinical decisions during hospitalization and enable early identification of infants with a higher risk of developing severe respiratory illnesses and long-term associated diseases. Viral bronchiolitis patients can be stratified based on their hospitalized wheezing status. Wheezing patients exhibited similar clinical patterns during hospitalization and long-term clinical outcomes upon discharge. Wheezing infants were more likely to develop preschool wheezing and asthma.
