Insights
Children with recurrent pneumonia (RP) and lower FEV1/FEF25-75 lung function may have an increased risk of non-cystic fibrosis (CF) bronchiectasis (BE). Spirometry may aid in early non-CF BE suspicion in pediatric RP cases.
Area of Science:
- Pediatric Pulmonology
- Respiratory Medicine
- Clinical Diagnostics
Background:
- Recurrent pneumonia (RP) is a common cause of pediatric non-cystic fibrosis (CF) bronchiectasis (BE).
- RP can lead to accelerated lung function decline in children.
- Early identification of non-CF BE in children with RP is crucial.
Purpose of the Study:
- To identify clinical factors for early suspicion of non-CF BE in children with RP.
- To analyze demographic, clinical, and lung function data of children with RP.
- To investigate the association between RP and the development of non-CF BE.
Main Methods:
- Retrospective analysis of 42 pediatric patients with RP.
- Inclusion of patients with and without non-CF BE diagnosed via high-resolution computed tomography.
- Recording of demographic, clinical data, and lung function test results (spirometry).
Main Results:
- 42 patients with RP were analyzed; 21 had non-CF BE, 21 did not.
- Chronic rhinosinusitis with post-nasal drip and recurrent wheezing were common in both groups.
- Significantly lower FEV1 and FEF25-75 values were observed in children with non-CF BE compared to those without.
Conclusions:
- Reduced FEV1 and FEF25-75 values are associated with an increased risk of non-CF BE in children with RP.
- Spirometry may be a useful diagnostic tool for early non-CF BE detection in pediatric RP.
- Further research is recommended to confirm the diagnostic utility of spirometry in these cases.
Background:
Recurrent pneumonia (RP) is one of the most frequent causes of pediatric non-cystic fibrosis (CF) bronchiectasis (BE) and a consequent accelerated decline in lung function. The aim of this study was to analyse the clinical records of children with RP in attempt to identify factors that may lead to an early suspicion of non-CF BE.
Methods:
We recorded the demographic and clinical data, and lung function test results of children without CF attending our outpatient RP clinic between January 2009 to December 2013 who had undergone chest high-resolution computed tomography ≥ 8 weeks after an acute pneumonia episode and ≤ 6 months before enrolment.
Results:
The study involved 42 patients with RP: 21 with and 21 without non-CF BE. The most frequent underlying diseases in both groups were chronic rhinosinusitis with post-nasal drip and recurrent wheezing (81 % and 71.4 % of those with, and 85.7 % and 71.4 % of those without BE). FEV1 and FEF25-75 values were significantly lower in the children with non-CF BE than in those without (77.9 ± 17.8 vs 96.8 ± 12.4, p = 0.004; 69.3 ± 25.6 vs 89.3 ± 21.9, p = 0.048). Bronchodilator responsiveness was observed in seven children with BE (33.3 %) and two without (9.5 %; p = 0.13).
Conclusions:
Reduced FEV1 and FEF25-75 values seem associated with an increased risk of developing non-CF BE in children with RP. This suggests a need for further studies to confirm the diagnostic usefulness use of spirometry in such cases.
