Streptococcal Toxic Shock Syndrome: A Case Report.

Area of Science:

• Infectious Diseases
• Critical Care Medicine
• Toxicology

Background:

• Streptococcal toxic shock syndrome (STSS) is a severe complication of Group A Streptococcus (GAS) infection, characterized by high mortality.
• Prompt diagnosis, intensive care, and surgical intervention are crucial for managing STSS patients.

Observation:

• A 65-year-old male with hypertension, diabetes, and peripheral arterial disease presented with leg pain, swelling, and fever.
• Initial diagnosis of cellulitis and UTI evolved into progressive multi-organ dysfunction, necessitating vasopressors, mechanical ventilation, and renal replacement therapy.
• Group A Streptococcus (Streptococcus pyogenes) was identified in blood cultures, leading to a diagnosis of STSS.

Findings:

• The patient received antibiotics, immunoglobulins, hemoperfusion, and corticosteroids, resulting in clinical improvement and resolution of the skin lesion.
• Despite the typically high mortality rate associated with STSS, this patient survived due to aggressive and multimodal treatment.
• The combination of immunoglobulin and hemoperfusion may have contributed to the favorable outcome.

Implications:

• This case underscores the importance of high clinical suspicion for STSS, particularly in diabetic patients with skin lesions.
• Prompt and intensive management, potentially including novel therapies like immunoglobulin and hemoperfusion, is vital for improving survival rates in STSS.
• Close surveillance and rapid treatment are essential once STSS is diagnosed.
