Applicability of standardized ultrasound examination to estimate disease activity in combination with JADAS and inflammation markers in JIA patients

Concept

This multicenter, international longitudinal study will recruit JIA patients (according to ILAR classification criteria) with active disease according to JADAS 10 and 27 scoring prior starting recommended treatment. All JIA relevant data (demographics, duration, disease activity, medication usage and treatment efficacy) will be collected and parent/guardian written consent obtained.

At enrolment and during predefined scheduled follow up visits (at 3 months up to 12 months) all JIA patients will be clinically evaluated by JADAS 10 and 27 scoring, examined by ultrasound gray-scale (GS) and Power Doppler (PD) in (44 joints) using OMERACT synovitis scoring system by an expert in pediatric ultrasound.

At each visit blood samples will be obtained for evaluation of inflammatory markers (such as cytokines, chemokines and S100A8, S100A9 and S100A12). In the case of disease worsening, the same parameters will be performed as unscheduled visit.

Objectives

  • to establish minimal corset of representative joints to be assessed by clinical examination and ultrasound to be used as outcome tool in JIA
  • to investigate if joint findings correlate with the panel of laboratory inflammation markers
  • tо evaluate sensitivity and predictive value of the multi-biomarker panel (clinical examination of the joints, ultrasound and inflammatory biomarkers) in JIA patients
  • to test if multi-biomarker panel could be applied in every day clinical practice to predict response to treatment and outcome tool in JIA
  • to improve possibility to achieve optimized personalized tailored treatment

Patient voice

Patient participation from local patient organizations will be crucial to explore which questions of interest have the greatest impact on the patient disease outcomes and treatment response. They should be involved in public engagement and inform wider society using different media if this project meets the needs of JIA patients.
