Abstract
We report a case of a 55-year-old woman with a history of type 2 diabetes mellitus, Charcot arthropathy and end-stage renal disease, who presented with a syncopal episode after undergoing haemodialysis. She had a history of methicillin-resistant Staphylococcus aureus (MRSA) bacteraemia from an unknown source 3 months earlier, which was treated with an 8-week course of intravenous antibiotics. At the time of presentation to the emergency room, she was found to be in refractory shock. Bedside echocardiogram was performed, which showed moderate pericardial effusion. The effusion was later found to be due to MRSA, which was identified in blood and in pericardial fluid cultures. The patient was successfully treated with intravenous daptomycin for 6 weeks. Acute osteomyelitis of her right foot was the source of the MRSA, for which a right below-knee amputation was ultimately performed.
