Di Nardo G, et al. - The clinicians aimed to examine whether allergic proctocolitis (a cause of self-limiting rectal bleeding in infants) could predispose to the development of functional gastrointestinal disorders (FGIDs) later in childhood. For the development of FGIDs in children, allergic proctocolitis was identified as a new risk factor. The data suggested that infection, as well as a transient early-life allergic inflammatory trigger, could induce persistent digestive symptoms, supporting the existence of “postinflammatory” FGIDs.
