title: Ultrasound Detection of Salmonella Septic Arthritis in a Rheumatoid Arthritis Patient on Anti-TNF Treatment.
abstract: We report a case of Salmonella septic arthritis detected by ultrasound in a 40-year-old man with rheumatoid arthritis while he was on anti-tumor necrosis factor-α monoclonal antibody certolizumab. An aspirate of his left elbow joint showed Salmonella enteritidis infection that was sensitive to ceftraixone. This was preceded by a brief episode of loose stools following a visit to the Far East. He was treated with antibiotics and made a good recovery. There have only been a few case reports of Salmonella septic arthritis in a rheumatoid arthritis patient on anti-tumor necrosis factor treatment but none previously in association with certolizumab.
