Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The human microbiota, a collection of microorganisms mostly settled in the gastrointestinal tract, plays a major role in the maintenance of the hosts' health and in development of disease as well. Exposure to different conditions early in life contributes to distinct "pioneer" bacterial communities, which shape the newborn infants' development and influence their later physiological, immunological and neurological homeostasis. Newborn infants with congenital malformations of the gastrointestinal tract (CMGIT), necrotizing enterocolitis (NEC), and spontaneous intestinal perforation (SIP) commonly require abdominal surgery and enterostomy. While intestinal microbiota has been extensively studied in infants with anatomically uninterrupted intestine, the knowledge of longitudinal intestinal colonization in this population is scarce.

This is an exploratory, observational, and longitudinal prospective study, primarily aimed to determine longitudinally the colonization of the proximal remnant intestine, in newborn infants with enterostomy after surgery (three weeks) for CMGIT, NEC and SIP. The secondary aim is to explore the associations of the colonization with the mode of delivery, gestational age, postnatal age, duration of fasting, type of enteric feeding, antimicrobial therapy, H2-receptor antagonist therapy, and length of proximal remnant intestine.

Newborn infants with enterostomy

Infants with enterostomy after surgery due to congenital malformations of the gastrointestinal tract, necrotizing enterocolitis, and spontaneous intestinal perforation

Exposure(s) of interest: enterostomy

Intervention Type PROCEDURE

Newborn infants with congenital malformations of the gastrointestinal tract, necrotizing enterocolitis, and spontaneous intestinal perforation commonly require surgery and enterostomy. In these infants samples of the enterostomy effluent will be collected and DNA extracted for microbiota identification.
