[Efficacy of exclusive enteral feeding as primary therapy for paediatric Crohn's disease].
BACKGROUND
The primary nutritional therapy (PNT), which consists in the administration of exclusive enteral formula feeds (polymeric, semi-elemental or elemental formula) for a period of no less than 6-8 weeks, has proven to be effective in inducing clinical remission in children with Crohn's disease. The clinical remission does not always include histological remission or cure of the mucosa. Faecal calprotectin is closely correlated with endoscopic and histological findings but is slightly associated with clinical activity scores.


METHODS
An observational prospective study including all patients under 14 years of age diagnosed with Crohn's disease between January 2002 and October 2007, and who were fed exclusively with polymeric formula (Modulen IBD, Nestle, Vevey, Switzerland) during the onset of the disease. Clinical controls were carried out (weight, height, body mass index [BMI) and the Paediatric Crohn's Disease Activity Index [PCDAI)) and faecal calprotectin was measured at the beginning and at weeks 4 and 8 of treatment. The clinical remission was defined as having a PCDAI less than or equal to 10. Faecal calprotectin values below 50 microg/g faeces were considered as normal.


RESULTS
There were 14 patients (9 males), mean age at diagnosis of 10.74 +/- 2.56 years. At week 4, 71 % of patients (10/14) had achieved clinical remission and a decrease in faecal calprotectin levels that was not significant. After 8 weeks, 85 % of our patients were in clinical remission and faecal calprotectin values had declined significantly without reaching normal levels.


CONCLUSIONS
Primary nutritional therapy administered over a period of 8 weeks is capable of inducing clinical remission and improving the degree of inflammation of the intestinal mucosa.
