Children (age <18 years) attending clinics in 3 paediatric gastroenterology referral centres in the UK in whom clinical assessment indicates that IBD is a possibility
Diagnostic Test: Intervention group
This group will provide a stool sample that will be analysed for VOCs and followed up after 3 months
- VOCs [ Time Frame: Visit 1-1day ]
For the VOCS identified by GCMS, consistent with our findings in adults (Ahmed 2016), we anticipate identifying a small number of VOCs that can be used to diagnose IBD and distinguish IBD from other common pathologies including functional abdominal conditions.
For the results generated by the GC-sensor (Odoreader©), we will compare the faecal VOC profile in children in whom IBD is confirmed with that in children with alternative diagnoses according to the advanced statistical methods required for determining and comparing VOC profiles.
- Underlying disease [ Time Frame: Visit 1-1 day ]Similar analyses as for the primary outcome will be used for the secondary outcomes. To shed light on underlying disease mechanisms in pIBD and other common conditionse will use existing KEGG databases to determine the source of faecal VOCs identified by GCMS, which will include bacteria, fungi, host tissues and metabolism (http://www.genome.jp/kegg/kegg2.html).
- Sub-group analysis [ Time Frame: Visit 1-1 day ]We will fully explore the data from our non-IBD children to identify characteristic faecal VOC profiles in common diagnostic groups (e.g. functional abdominal pain, coeliac disease) and also demographic and environmental factors (e.g. age, sex, diet) using the approaches described above.
