Reactive Arthritis Induced by Bacterial Vaginosis: Prevention with an Effective Treatment

We report a 42-year-old woman with reactive arthritis induced by bacterial vaginosis who presented with oligoarthritis with an additive form, arthralgia, and enthesitis. She hasn’t had a history of diarrhea or dysuria or vaginal secretion, or sexually transmitted infections (STIs). The laboratory tests were normal except for a high erythrocyte sedimentation rate (ESR). Her pelvic examination revealed homogeneous white grey and malodorous vaginal discharge on the vaginal wall and Pap smear and Gram-stained smear of vaginal swab was consistent with bacterial vaginosis. She responded to metronidazole therapy and her six-month follow up hasn’t shown recurrence of arthritis. As reactive arthritis (ReA) is a paradigm of a rheumatic disease in which the initiating infectious cause is known, so early use of antimicrobial drugs may prevent the development of musculoskeletal symptoms which are triggered by infections.
