Lung function in children with recurrent bronchitis
Insights
Recurrent bronchitis in children often leads to lung function disorders, including increased lung resistance and bronchial hypersensitivity. These early signs may predict future chronic obstructive bronchitis in adults.
Area of Science:
- Pediatric Pulmonology
- Respiratory Medicine
- Child Health
Background:
- Recurrent bronchitis is common in young children, impacting their respiratory health.
- Early identification of lung dysfunction is crucial for preventing long-term respiratory issues.
Purpose of the Study:
- To investigate lung function in children with recurrent bronchitis.
- To identify potential early indicators of chronic obstructive bronchitis.
Main Methods:
- Studied lung mechanics, functional residual capacity, blood gases, and regional lung function in 29 children.
- Assessed lung function parameters in relation to recurrent bronchitis episodes.
Main Results:
- Most children (73%) aged 1-7 years showed functional disorders.
- Common findings included increased lung resistance (22/29), decreased dynamic compliance (15/23), and bronchial hypersensitivity (12/17).
- Regional ventilatory and perfusion malfunctions were also observed.
Conclusions:
- Children with recurrent bronchitis exhibit significant lung function abnormalities.
- These functional disorders may represent early bronchial lesions, potentially leading to chronic obstructive bronchitis in adulthood.
Abstract:
Lung function was studied in 29 children suffering from recurrent bronchitis (average number of bronchitis attacks per year: 4.2 +/- 0.5). Most of them (73%) were 1--7 years old. The date of exploration in relation to the last acute bronchitis was on average 6 weeks. Lung mechanics, residual functional capacity, blood gases and regional lung function were measured. Most of the children were suffering from some kind of functional disorder; alteration of lung mechanics -- increase of lung resistance (22/29) decrease of dynamic compliance (15/23); increase of functional residual capacity (6/10), non specific bronchial hypersensitivity (12/17); regional ventilatory and perfusion malfunction. These functional disorders could be the first evidence of the bronchial lesions which cause chronic obstructive bronchitis in adults.
