[Reactive arthritis induced by Clostridium difficile enteritis]. / Monoarthrite associée à une entérocolite à Clostridium difficile.

ABSTRACT

This article reports the case of an acute monoarthritis of the ankle occurring in a HLA-B27 positive female patient who presented with diarrhea and fever. We retained the hypothesis of a Clostridium difficile colitis, as she had previously received an antibiotic treatment. The culture of the synovial fluid remained sterile, which postulated that this arthritis was reactive. The diagnosis was confirmed by the presence of toxins A and B in the stool and positive culture. The outcome was satisfactory with metronidazole therapy.
