- OBJECTIVES: Joint destruction is a hallmark of juvenile idiopathic arthritis (JIA). Clinical evaluation and radiographic imaging are current methods to identify destruction. Biomarkers could aid an earlier and more sensitive diagnosis. Our aim was to investigate levels of bone and cartilage degradation biomarkers in JIA patients, compared to healthy children or juveniles with knee injuries. METHODS: Triple-paired synovial fluid, plasma and urine samples from 29 JIA patients were compared to 61 plasma samples from healthy children and synovial fluid from 41 knee-injured juveniles. Cartilage biomarkers ARGS neoepitope of aggrecan (ARGS), cartilage oligomeric matrix protein (COMP), type II collagen epitope (C2C), bone biomarkers N-terminal type I collagen cross-linked telopeptide (NTX-I) and tartrate-resistant acid phosphatase 5b (TRAP5b) were analysed by immunoassays. RESULTS: Plasma levels of ARGS, C2C, COMP and TRAP5b were increased in JIA compared to healthy children. Compared to knee-injured juveniles, synovial fluid C2C and TRAP5b were increased in JIA, while ARGS and COMP were decreased. For JIA patients, local (synovial fluid) and systemic (plasma/urine) levels of bone biomarkers correlated positively; age correlated negatively to plasma levels of C2C and TRAP5b; no correlation was found between biomarkers and gender, affected joint count, disease duration or medication. CONCLUSIONS: Elevated levels of destruction biomarkers in JIA compared to healthy children indicate a potential to serve as clinical tools for destructive joint disease. High levels of TRAP5b, NTX-I and collagen II in JIA in contrast to more pronounced aggrecan and COMP degradation in juvenile knee injuries, suggests that JIA patients have a unique biomarker pattern, different from healthy and knee-injured children.
