AIM

This study investigated the prevalence of extraintestinal manifestations (EIM) in paediatric coeliac disease and their associations with other disease features.

METHODS

Researchers at the University of Tampere, Finland, compared EIM in 511 children diagnosed with coeliac disease from 2003 to 2014 and 180 diagnosed with functional gastrointestinal disorders from 2007 to 2013. Disease severity and dietary responses were also compared between coeliac children diagnosed by screening (n = 146) or because of EIM (n = 116) or gastrointestinal symptoms (n = 249).

RESULTS

Coeliac patients had more EIM (62%) than those with functional disorders (33%). The most common EIM in coeliac children were poor growth (27%) and anaemia (18%). Children with coeliac disease often showed fatigue (8%) and symptoms affecting the skin (15%), nervous system (9%) and joints (6%). Coeliac patients with EIM as their main clinical presentation had more severe symptoms and histological damage at diagnosis than those with gastrointestinal presentation and screen-detected cases. The subgroups did not differ with regard to other clinical and laboratory parameters and dietary adherence. Concomitant EIM were also common in children diagnosed because of gastrointestinal presentation (60%) and by screening (37%).

CONCLUSION

EIM were common in coeliac disease and associated with more severe clinical and histological presentation.
