Inflammatory metabolites in exhaled breath condensate characterize the obese respiratory phenotype

In this study we aimed at verifying if NMR-based metabolomics of EBC, combined with orthogonal projections to latent structures-discriminant analysis, could possibly recognize specific biomarkers to map the obese metabolic respiratory phenotype. Obese and lean control subjects could be distinguished in a statistical model presenting high quality parameters (R2 = 0.904 and Q2 = 0.871). Identified airway metabolites linked to the inflammation processes demonstrate that obesity constitutes a specific inflammatory metabolic phenotype (metabotype). It is concluded that the noninvasive EBC matrix is suitable to selectively investigate the obesity-related lung inflammation.
