RESUMO
INTRODUCTION: Reactive arthritis due to Clostridium difficile infection is uncommon. CASE REPORTS: We report two cases of reactive arthritis associated with C. difficile infection that occurred in a 40-year-old woman and a 47-year-old man. The literature review between 1976 (date of first reported case) and 2016 retrieved 54 observations (including our two cases). Reactive arthritis occurs most frequently in young subjects after a variable time frame according to C. difficile infection, involving one or several articulations. The issue is generally favourable with or without anti-inflammatory treatment. CONCLUSION: The increasing incidence of C. difficile infection makes more likely the occurrence of this related reactive arthritis. Therefore physicians should consider it in differential diagnosis of bacterial infections capable of causing reactive arthritis.
