Congenital Lobar Emphysema in Children: Case Series

Recurrent wheezing is very common in infants. When these symptoms appear early without a free interval, a pulmonary malformation should be investigated. Congenital lobar emphysema is a rare abnormality of the lower respiratory tract. Here, we report a case series of six cases of congenital lobar emphysema between 2015 and 2023. Clinical and radiological data were collected according to an operating sheet previously established in our pediatric pneumo-allergology unit. They all had recurrent wheezing and dyspnea. Chest radiography and chest CT were consistent with the diagnosis of congenital lobar emphysema. All patients had lobectomy without complications.

Congenital pulmonary malformations: metabolomic profile of lung phenotype in infants

BACKGROUND

The main hydrosoluble metabolites in three different human congenital pulmonary malformations are described by nuclear magnetic resonance (NMR) spectroscopy.

METHODS

Bronchogenic cyst (BC), congenital lobar emphysema (CLE) and intrapulmonary sequestration (IPS), were analyzed with respect to a control sample. The extracted metabolites were submitted to high-resolution (1)H NMR-spectroscopy.

RESULTS

Congenital lung malformations showed free choline, phosphocoline and myoinositol high levels. IPS and CLE were found increased in lactic acid/glucose ratio. Lactic acid and glucose values resulted to be more elevated in control sample.

CONCLUSIONS

Congenital lung lesions showed different metabolomic profiles useful for early diagnosis.
