Synovial calprotectin: A potentially useful biomarker for the diagnosis of Kingella kingae native arthritis

Anne-Gallë Leroy et al. Clin Case Rep. .

Abstract

Kingella kingae is a bacteria involved in developing arthritis in children. Its diagnosis remains difficult. We report a case for which a new biomarker, calprotectin measured in the synovial fluid, was strongly positive and a specific molecular test was the only way to diagnose it specifically.

Keywords: Kingella kingae; calprotectin; septic native arthritis.
