Intestinal fatty acid binding protein is a disease biomarker in paediatric coeliac disease and Crohn's disease.

Background: There is a clinical need to develop biomarkers of small bowel damage in coeliac disease and Crohn's disease. This study evaluated intestinal fatty acid binding protein (iFABP), a potential biomarker of small bowel damage, in children with coeliac disease and Crohn's disease.

Methods: The concentration iFABP was measured in plasma and urine of children with ulcerative colitis, coeliac disease, and Crohn's disease at diagnosis and from the latter two groups after treatment with gluten free diet (GFD) or exclusive enteral nutrition (EEN), respectively.

Dietary triggers of gut inflammation following exclusive enteral nutrition in children with Crohn's disease: a pilot study.

Background: The anti-inflammatory effect of exclusive enteral nutrition on the gut of children with Crohn's disease is rapidly lost after food reintroduction. This study assessed disease dietary triggers following successful treatment with exclusive enteral nutrition.

Methods: Nutrient intake, dietary patterns and dietary biomarkers in faeces (gluten immunogenic peptides, undigestible starch, short chain fatty acids) were assessed in 14 children with Crohn's disease during early food reintroduction, following exclusive enteral nutrition.

The reduction of faecal calprotectin during exclusive enteral nutrition is lost rapidly after food re-introduction.

Background: Faecal calprotectin decreases during exclusive enteral nutrition in children with active Crohn's disease. It is unknown how faecal calprotectin changes during food re-introduction and the influence of maintenance enteral nutrition.

Aims: To study changes to faecal calprotectin during exclusive enteral nutrition and at food reintroduction, and explore associations with maintenance enteral nutrition.
