Characteristics of polymeric formula and route of delivery of exclusive enteral nutrition have no effect on disease outcome and weight gain in pediatric Crohn's disease.

BACKGROUND & AIMS: This study aimed to evaluate the effect of the route of exclusive enteral nutrition (EEN) delivery (orally or via nasogastric (NG) tube) and type of polymeric formula (with taste vs tasteless and isocaloric vs hypercaloric) on the disease outcome and nutritional status in children with Crohn's disease (CD).

METHODS

This was a single center retrospective study which included all CD patients whose active disease at diagnosis was treated with EEN in the period from October 2007 to November 2017. All patients received polymeric formula orally or through a NG tube, which was based on the physicians and child's preference.

RESULTS

A total of 92 CD patients were included in the study (mean age 13.6 ± 3.0 years; 45.7% female). Overall, 42 (45.7%) patients received EEN via NG tube until the end of the EEN period. Remission was achieved in 71 (77.2%) children. There was no difference in the EEN failure status, remission duration, inflammatory markers, and weight gain at the end of the EEN period between oral intake and NG tube groups. None of the factors including age, disease location, type of formula (with taste vs tasteless and isocaloric vs hypercaloric) and mode of delivery (orally vs through NG tube for the whole duration of EEN) demonstrated an association with EEN failure.

CONCLUSION

This study failed to demonstrate an effect of the route of EEN delivery and the characteristics of the polymeric formula on the outcome of treatment in pediatric patients with CD.
