Accurate phenotyping is essential in pediatric CD, as this affects the management of individual patients. Disease phenotypes differ according to age at disease onset. The Paris classification is a useful tool to capture the variety of phenotypic characteristics of pediatric CD.
Extensive disease and rectal sparing are age-dependent phenotypes in pediatric UC. Rectal sparing, cecal patch, backwash ileitis, and gastric erosions are not uncommon at diagnosis, while gastric ulcerations and erosions in the duodenum or esophagus are. Recognition of atypical phenotypes in pediatric-onset UC is crucial to prevent misclassification of IBD.
The quality of diagnostic workup in paediatric patients with IBD increased steadily between 2004 and 2009. Small-bowel imaging by magnetic resonance imaging superseded the use of small-bowel follow-through. OGD and ileal intubation contributed to a definitive diagnosis of CD.
SUMMARY BackgroundInfliximab is effective for induction and maintenance of remission in children with moderately to severely active Crohn's disease (CD).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
