In 2009, a large prospective database involving Italian Pediatric Gastroenterologists was established.  A recent study describes the classification (Paris) and phenotype of early-onset pediatric inflammatory bowel disease (EO-IBD) (Inflamm Bowel Dis 2014; 20: 597-605).

In 506 consecutive patients, 224 had Crohn’s disease (CD), 245 ulcerative colitis (UC) and 37 IBD-unclassified.

Key findings:

• 11% were aged 0-5 years, 39% 6-11 years, 50% were 12-18 years.
• UC was more frequently diagnosed in 0-11 years of age whereas as CD was more common in 12-18 years.
• EO-Crohn’s showed more frequent isolated colonic disease
• EO-UC noted 62% with pancolitis compared with 38% in 6-11 years and 31% in 12-18 year group

Take-home message: The authors conclude that “EO-IBD exhibits an extensive phenotype and benefit from aggressive treatment strategies, although surgical risk is similar to later-onset disease. A family history for IBD is not common in EO disease.”
