Potential role of the detection of enterobacterial DNA in blood for the management of neonatal necrotizing enterocolitis.

We present three cases of pre-term low-weight infants with suspected necrotizing enterocolitis (NEC) [one eventually recognized as a connatal cytomegalovirus (CMV) infection], microbiologically monitored using a molecular assay detecting bacterial and fungal DNA in blood. The detection of DNA from enteric pathogens in blood was interpreted as a sign of ongoing perforation, and represented a useful complement in the management of the presented cases. Moreover, these cases suggest the opportunity for larger future studies to assess the possible role of a molecular approach in the close monitoring of infants with suspected NEC or with other conditions at-risk for intestinal perforation.
