Evaluation of the Efficacy and Tolerability of an Exclusion Diet in Patients With Juvenile Idiopathic Arthritis: Interventional, Exploratory Single-center, Randomized, Controlled, Open-label, add-on Study

Conditions
Summary
The JIA-ED study is a pilot project. Based on experience in another inflammatory disease, a 4-week period was extrapolated as sufficient to assess the effectiveness of the experimental intervention. This observation is supported by literature data showing that, halfway through phase I of the CDED (Crohn Diseasse Exclusion Diet), it is already possible to identify a subset of patients with Crohn's disease who are responsive to the dietary treatment and who also have a higher likelihood of achieving clinical remission by the end of the first phase of the diet itself.
Eligibility
Inclusion Criteria5
- Confirmed diagnosis of juvenile idiopathic arthritis (JIA) in the forms of enthesitis-related arthritis and oligoarticular forms according to the ILAR 2001 criteria (https://medicalcriteria.com/web/reujia/);
- Age between 6 and 18 years (not yet 18);
- Active disease of mild to moderate severity, assessed through the Juvenile - Arthritis Disease Activity Score (JADAS10) tool (Trincianti C. et al., American College Rheumatology, 2021);
- For study groups 2 and 3: failure of ongoing pharmacological therapy at the time of screening, defined as a failure to achieve at least a 20% reduction in JADAS10 values after 3 months of initiating DMARD therapy or biologic medication, or if the disease is inactive on such therapy, a 20% increase in those values;
- Signed informed consent.
Exclusion Criteria4
- Patients requiring systemic immunosuppressive therapy for active uveitis;
- Patients undergoing therapy with systemic corticosteroids (defined as prednisone equivalent >0.5 mg/kg for >7 days) or intra-articular corticosteroids in the 3 months prior to enrollment;
- Patients with fecal calprotectin values > 250 mcg/g at the time of screening;
- Use of antibiotics in the month prior to enrollment.

Interventions
The dietary intervention attempts to induce remission in the first 4-week treatment without any change in the pharmaceutical therapy. In case of worsening or not reaching the outcomes, the patient will be defined as a failure and start rescue therapy with the standard of care.
