Chronic Non-inflammatory Pains in Rheumatopediatrics

Juvenile idiopathic arthritis is the most frequent pathology in paediatric rheumatology clinic. Pain is an important symptom in paediatric rheumatology. It is actually poorly studied and is not evaluate in disease activity score like the Juvenile Arthritis Disease Activity Score (JADAS). It is source of handicap, social and psychological distress and greatly contribute to poor quality of life. Chronic pain is frequently multifactorial, even in inflammatory disease. In adult population, rheumatologists have shown an association between inflammatory disease like spondylarthritis or rheumatology polyarthritis and fibromyalgia. There is no specific data on chronic pain in juvenile idiopathic arthritis. Pain is mostly evaluated by the Visual Analogue Scale (VAS) with no evaluation of pain repercussion on daily life or its chronicity. This study's primary objective is to determine the frequency of chronic pain and its relationship with disease activity. Secondaries objectives are to determine repercussion of pain in daily life, and risk factor of chronic pain. To responded to this objective, we will conduct a transversal study in a paediatric rheumatology refence centre in Necker-Enfants malades Hospital. We will include all patients between 12 and 18 years old followed in our centre for any type of juvenile idiopathic arthritis. Patients will be evaluated as usual by their paediatrics rheumatologist during a follow-up consultation or hospitalisation with the used of the clinical JADAS. Patient accepting to participate the study will be given a paper questionnaire evaluating chronic pain, its repercussion, anxiety (by the used of the Revised Children's Manifest Anxiety Scale (RCMAS score)), depression (by the used of the Children's Depression Inventory (CDI score)), Sleepiness (by the used of the Pediatric Daytime Sleepiness Scale (PDSS score)) and quality of life (by the used of the measurement model for the Pediatric Quality of Life inventory (PedQL score)).
