Development of extraintestinal manifestations in pediatric patients with inflammatory bowel disease

In our large cohort of pediatric IBD patients, 6% had at least 1 EIM before diagnosis of IBD. At least 1 EIM will develop in 29% within 15 years of diagnosis. The incidence of EIMs both before and after diagnosis of IBD differs by type of EIM and may be slightly higher in girls, but is independent of the type of IBD, age at diagnosis, and race/ethnicity.
