The present study aimed to provide evidence on whether children at risk of gastrointestinal inflammation have increased measurements of faecal calprotectin (FC). FC was measured in 232 children; 55 children (n = 11 treatment naïve) with juvenile idiopathic arthritis (JIA), 63 with coeliac disease (CD); 17 with new diagnosis before and after treatment on gluten-free diet and 114 controls. None of the treatment-naive children with JIA had raised FC. Four JIA patients on treatment had a raised FC but in all cases a repeat test was normal. In newly diagnosed patients with CD, the median (interquartile range) FC was higher 36.4 (26-61) than that in controls 25.0 (23-41) mg/kg (P = 0.045) but this significantly decreased 25 (25-25) mg/kg (P = 0.012) after 6 months on gluten-free diet. Random measurements of FC are not raised in children with JIA or CD. A significant elevation of FC in these groups is not explained by their diagnosis and therefore needs further investigation.
