Streptococcal Toxic Shock Syndrome: A Case Series Emphasizing the Urgency of Recognition and Tailored Treatment

Abstract

Background

Streptococcal toxic shock syndrome (TSS) is a rare but lethal condition associated with Streptococcus Pyogenes Group A (GAS). With rising incidence and high mortality, timely recognition and management are crucial. This case series presents two adult TSS cases caused by invasive GAS, highlighting the importance of early identification and multidisciplinary management.

Case Presentations

The first case involves a 42-year-old male who presented with fever, dizziness, and a tender, erythematous olecranon following an elbow laceration. Despite negative imaging for necrotizing fasciitis, a positive throat swab for GAS prompted immediate broad-spectrum antibiotics and aggressive resuscitation. Clindamycin and intravenous immunoglobulin were administered. The patient developed TSS and acute kidney injury, requiring intensive care and hemodialysis. The second case features a previously healthy 43-year-old female presenting with systemic symptoms and a rash, without trauma history. Positive GAS blood cultures confirmed TSS, leading to similar management and subsequent renal complications requiring hemodialysis.

Why Should an Emergency Physician Be Aware of This?

These cases highlight the evolving epidemiology of invasive GAS infections and the associated risk of TSS. Early identification and appropriate tailored treatment are essential to reduce morbidity and mortality, especially given the recent surge in invasive GAS. Clinical vigilance for skin changes and thorough laboratory investigations, including non-sterile site cultures, are critical. Early identification enables the use of adjunctive treatments like clindamycin and IVIG, and facilitates appropriate de-escalation of antibiotics. Prompt consultation with infectious disease, intensive care, and surgical teams is necessary to ensure optimal treatment.
