Inflammatory Bowel Disease Across the Age Continuum: Similarity and Disparity
- 72 Downloads
To identify similarities and differences between the pediatric-onset and adult-onset Inflammatory Bowel Disease (IBD) based cohorts and further characterize the pediatric cohort.
A retrospective analysis of pediatric patients attending the tertiary referral care gastroenterology center from 2004 to 2016 was conducted. All the patients were clinically evaluated, investigated and followed up at the centre.
Sixty five patients with pediatric IBD were compared with 216 patients with adult-onset IBD. The Ulcerative colitis: Crohn’s disease (UC:CD) ratio was higher in adult-onset population (2.29:1 vs. 1.7:1). Predominant symptoms in pediatric UC were diarrhea and passage of blood in stools; whereas those in pediatric CD were abdominal pain and failure to gain weight. Ulcerative proctitis was less common (2.4% vs. 18.8%; p = 0.009) and an extensive disease (pancolitis) was more common in the pediatric population (73.1% vs. 30.2%; p < 0.00001). Adult CD had higher L3 (33.3% vs. 46.1%; p = 0.28) disease; whereas in pediatric CD, L1 disease (37.5% vs. 32.3%; p = 0.65) was predominant. There was no difference with respect to penetrating and stricturing complications of CD in adults vs. children (20.8% vs. 23.1%; p = 0.974). 5-ASA agents were used more commonly in the pediatric IBD population (96.9% vs. 79.9%; p = 0.0034) as compared to adults whereas corticosteroids (87.5% vs. 76.9%; p = 0.28) and infliximab (25% vs. 9.2%; p = 0.054) were used more frequently in the pediatric CD subgroup as compared to adult CD subgroup.
IBD has significant disease heterogeneity according to the age of onset. Pediatric IBD has distinctive features that set it apart from adult-onset IBD.
