Clinical Trial Summary

The aim of this study is to explore if an already established diet with anti-inflammatory effect in paediatric inflammatory bowel disease would have an anti-inflammatory effect in children with JIA. The diet is called specific carbohydrate diet.

Description:

Children classified with JIA, in a low-to-medium disease activity and without having changed DMARD or bDMARD in the last 12 weeks are included. Only motivated children and parents can participate. Before inclusion the family are informed orally about the study plan, the diet and practical issues regarding the study and they receive written information including for example a product list and a recipe booklet. A dietician and the principal investigator follows the child and parents during visits, by mail and phone. After the baseline visit, the family has two weeks to get used to the new diet. At baseline, after two, four and twelve weeks on the diet the child is examined, blood exams are performed and blood is stored at -70, fecal samples and urine is also collected. At inclusion and after four weeks saliva sample for bacteria is collected. The child fills in the child health assessment questionnaire, (CHAQ) for a score of the physical ability and DisabKids for an overall assessment of the childs well-being.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in number of inflamed joints	Physical examination	At baseline compared to four weeks of intervention
Primary	Change in CHAQ, child health assessment questionnaire	A questionnaire for assessment of physical function, min-max, 0-3. A higher score means worse physical function	At baseline compared to four weeks of intervention
Primary	Change in overall well-being	Global assessment visual analogue scale (VAS), for the patient min-max, 0-10 cm. A higher score means worse overall well-being	At baseline compared to four weeks of intervention
Primary	Change in assessment of pain: visual analogue scale	Global assessment visual analogue scale (VAS) for Pain, min-max, 0-10 cm. A higher score means more pain	At baseline compared to four weeks of intervention
Primary	Change in assessment of morning stiffness	Number of minutes	At baseline compared to four weeks of intervention
Secondary	Change in Microbiota in fecal samples	16sSrRNA and Metagenomics	At baseline compared to four weeks of intervention
Secondary	Change in Short chain fatty acids in fecal samples	Analysed, using a HPLC-machine, Agilent technology 1100-series, presented in mg/gr	At baseline compared to four weeks of intervention
