Clinical Trial Summary

Idiopathic juvenile arthritis includes 20% of patients with arthritis with enthesitis or juvenile spondyloarthropathy. This is treated with anti-inflammatory drugs and then followed by biotherapy with DMARDs (Drugs Modifying the Activity of Rheumatic Disease) if the former are insufficient. Methotrexate (MTX) may also be used before these biotherapies. Recently, in adults, a particular profile of intestinal microbiota has been shown to alter the availability of MTX making it in efficient. Knowing that pediatric patients with juvenile spondyloarthropathy have an imbalance of their intestinal flora (dysbiosis) the investigators wanted to explore whether DMARDs could have a similar impact on the microbiota of these young patients and alter the response to treatment.
