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 H-1 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.
