Staphylococcal toxic shock syndrome: mechanisms and management.

Staphylococcal toxic shock syndrome is a rare complication of Staphylococcus aureus infection in which bacterial toxins act as superantigens, activating very large numbers of T cells and generating an overwhelming immune-mediated cytokine avalanche that manifests clinically as fever, rash, shock, and rapidly progressive multiple organ failure, often in young, previously healthy patients. The syndrome can occur with any site of S. aureus infection, and so clinicians of all medical specialties should have a firm grasp of the presentation and management. In this article, we review the literature on the pathophysiology, clinical features, and treatment of this serious condition with emphasis on recent insights into pathophysiology and on information of relevance to the practicing clinician.
