Early onset inflammatory bowel disease: manifestations, genetics and diagnosis

Özet

Crohn’s disease and ulcerative colitis are immunologically mediated chronicinflammatory conditions, collectively referred to as inflammatory boweldiseases (IBD). While most studies have described the condition in the adultpopulation, recent evidences suggest that IBD in children may represent anetiologically distinct disease from the adult onset IBD. Since a significantproportion of patients diagnosed with IBD demonstrate their clinicalmanifestations during childhood, knowledge about the disease progression,severity and diagnosis in this particular patient population is crucial. Therefore,in the present study, the clinical manifestations, recent advancements in thegenetics of early onset IBD and the clinical approach to diagnoses of IBD inchildren are described.
