Abstract

AIMS:

Faecal calprotectin, a neutrophil cytosolic protein, is raised in inflammatory bowel disease. We assessed this investigation in evaluating children with chronic intestinal symptoms.

METHODS:

Stool samples from 100 children aged 5-17 years (referrals to the regional paediatric gastroenterology service) were tested using a commercially available kit.

RESULTS:

Calprotectin was higher in inflammatory bowel disease than normal children (p<0.0001) or in those with functional constipation (p<0.0001). The overall specificity for organic bowel disorders was 85%. Calprotectin correlated with C-reactive protein in inflammatory bowel disease (p=0.001), and clinical disease activity in ulcerative colitis (p=0.017), but not with disease activity in Crohn's disease.

CONCLUSION:

Raised faecal calprotectin should prompt further assessment in children with chronic intestinal symptoms, since an organic bowel disorder is likely. However, calprotectin cannot be regarded as a specific test for idiopathic inflammatory bowel disease.
