Metabolomics in necrotizing enterocolitis: the state of the art

Necrotizing enterocolitis (NEC) is a serious inflammation of the bowel that most often affects premature infants. The exact cause of NEC is still poorly understood but investigators believe that these different factors can play an important role: prematurity and immaturity of the intestine of the preterm newborns, differences in the intestinal bacterial colonization and an abnormal immune response. Since the early symptoms of NEC are often rather non-specific, the diagnosis of NEC can be difficult. Therefore, the search for diagnostic biomarkers for NEC remains warranted. This review focuses on the results of recent metabolomics investigations on NEC, providing important contributions to the understanding of the biochemical process characterizing this disease
