Changes in Pulmonary Function and Controlled Ventilation-High Resolution CT of Chest After Antibiotic Therapy in Infants and Young Children with Cystic Fibrosis
2015
Overview
Background
Infants with cystic fibrosis (CF) develop early progressive lung disease which may be asymptomatic. Infant pulmonary function tests (IPFT) and controlled ventilation-high resolution computed tomography (CV-HRCT) of chest can detect early asymptomatic lung disease. It is not well established that these objective measures can detect changes in lung disease after clinical interventions.
Objective
The purpose of this study was to evaluate usefulness of IPFT and CV-HRCT to detect changes in lung disease after intravenous (IV) antibiotic therapy in infants with early CF-related lung disease.
Study Design
IPFTs and CV-HRCT done before and after 2 weeks of IV antibiotics in infants at our institution over the last 12 years were compared. CV-HRCTs were compared using the modified Brody scoring system.
Results
The sample included 21 infants, mean age 85.2 ± 47.6 weeks. Mean change in weight was 0.4 ± 0.38 kg (
p
= 0.001). Significant changes in IPFT included mean % predicted FEV
0.5
(+13.5 %,
p
= 0.043), mean %FEF
25–75
(+30.2 %,
p
= 0.008), mean %RV/TLC (−11.2 %,
p
= 0.008), and mean %FRC/TLC (−4.5 %,
p
= 0.001). Total Brody scores improved from a median of 10 to 5 (
p
< 0.001) as did mean scores for airway wall thickening (
p
= 0.050), air trapping (
p
< 0.001), and parenchymal opacities (
p
= 0.003).
Conclusion
IPFT and CV-HRCT can be used as objective measures of improvement in lung disease for infants with CF treated with antibiotics.
