Septic Knee Arthritis Caused by Group B Salmonella Species in a Patient with Systemic Lupus Erythematosus / 대한정형외과학회잡지

Infection is a leading cause of death in patients with systemic lupus erythematosus (SLE). Insufficiency of the reticuloendothelial system, immunosuppressive therapy and inadequate opsonization are the main predisposing factors for infection. Salmonella infection is one of the most common opportunistic bacterial infections in patients with SLE and it can provoke a bacteremia or a localized infection. We report here on a rare case of septic knee arthritis caused by Group B Salmonella in a SLE patient, and this was treated with arthroscopic irrigation and antibiotics.
