Scientists hunt for clues to tell infection apart from inflammation in Kids' joints
NCT ID NCT03827759
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked for new markers in blood and joint fluid to help doctors tell the difference between septic arthritis (a joint infection) and juvenile idiopathic arthritis (an inflammatory condition) in children. Researchers planned to analyze samples from 100 children under 15 with acute arthritis. The study was terminated early, so results may be limited.
