Effect of short-term partial enteral nutrition on the treatment of younger patients with severe Crohn's disease.

BACKGROUND/AIMS: To analyze the effect of short-term supportive temporary partial enteral nutrition therapy for treating severe pediatric Crohn's disease (CD).

METHODS

We conducted a prospective, open-label study in pediatric patients with CD (n=78) from January 2007 to December 2011. The CD patients were divided into three groups according to disease severity (mild, moderate, and severe). Seventeen patients with severe CD received short-term partial enteral nutrition (SPEN) in addition to their general diet for 4 weeks after the induction of remission with medical treatment. This SPEN group was further divided into two groups by age (<13 years, ≥13 years). Nutritional parameters and Pediatric Crohn's Disease Activity Index scores were analyzed at the initial enrollment and following 1 year of treatment for all groups.

RESULTS

Nutritional status improved substantially after 1 year of treatment in the severe CD group. Nutritional status in the SPEN group improved considerably more than that in the non-SPEN group. Additionally, the <13-year-old group demonstrated better nutritional status improvement than the ≥13-year-old group.

CONCLUSIONS

SPEN may be effective in pediatric patients with severe CD for improving nutritional status and moderating disease severity.
