N2 - OBJECTIVES: The aim of this study was to investigate a possible association between extraintestinal manifestations (EIM) and a more severe disease course in pediatric onset inflammatory bowel disease (pIBD).METHODS: This study compares the disease course of pIBD patients (IBD diagnosis <15 years of age) with and without EIM in a population-based cohort from Denmark. Patients diagnosed with pIBD between 1998 and 2008 were included in the study and followed until December 31, 2014. Data on phenotype, treatment, relapses, and the temporal relationship between IBD relapses and activity of EIM were collected at end of follow-up by manual revision of patient charts.RESULTS: Of 333 pIBD patients, 14 (4.2%) had EIM at time of diagnosis and 47 (14.1%) developed EIM during follow-up. Median follow-up time was 9.6 years for patients with EIM and 8.8 years for patients without. In ulcerative colitis, EIM were associated with an increased risk of biological treatment and surgery (hazard ratio: 2.6; 95% confidence interval [CI]: 1.3-5.5, P = 0.008 and 2.9 [95% CI: 1.1-7.7, P = 0.03], respectively). In Crohn disease, EIM were associated with an increased relapse rate (1.3 [95% CI: 1.1-1.5], P = 0.001). Lastly, we found a positive temporal relationship between relapse of IBD and EIM activity.CONCLUSION: The presence of EIM is associated with a more severe disease course in pIBD. This should be considered when deciding treatment options, as a more aggressive treatment approach could be warranted in patients with EIM. However, prospective studies are needed to fully evaluate this.
