Covert multi-focal infective arthritis

Six patients with pre-existing rheumatic joint disease presented with overwhelming septicaemia but without overt signs of joint inflammation. Joint aspirates demonstrated multifocal staphylococcal infective arthritis. Despite intensive care all six died from the infection or its immediate sequelae. The contrast between this clinical entity and classical infective arthritis, presenting with one or more swollen, tender joints, is discussed.
