Predicting Remission in Pediatric Ulcerative Colitis

Trying to offer realistic information to families on the long-term success of infliximab (Remicade) for pediatric ulcerative colitis has been difficult due to a limited amount of data.  In addition, many studies have a number of limitations which can make it difficult to extrapolate to a less-selected population (According to the study which you would never qualify for ).

A recent post hoc analysis (Clin Gastroenterol Hepatol 2013; 11: 1460-65) from 51 children (age 6-17 years) provides some insight into this issue.  The authors used data collected prospectively during the T72 clinical trial (Clin Gastroenterol Hepatol; 10: 391-99 -reviewed in blog post: Infliximab for children with Ulcerative Colitis | gutsandgrowth).


  • Week 8 PUCAI scores best predicted which patients would be in steroid-free remission after 1 year of treatment: 9 of 17 (53%) with scores <10 points were in sustained remission compare with 4 of 20 (25%) with scores ≥10.
  • Week 8 PUCAI outperformed mucosal healing in predicting remission.

Key points:

  • PUCAI may have outperformed mucosal healing because the latter can lag behind clinical response.  Furthermore, mucosal healing is more subjective with less interobserver reliability.
  • In patients with known inflammatory bowel disease, endoscopic assessment remains important in several situations: condition or reason for symptoms is in question (eg. exclude irritable bowel symptoms or medication-induced symptoms), acute severe colitis not responding to 3-day treatment with intravenous steroids to exclude superinfection, and to assess mucosa before major treatment changes “such as when starting or stopping biologics and before referral for colectomy.”
