ABSTRACT
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. STUDYDESIGN:
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.
