Septic scarlet fever due to Streptococcus pyogenes cellulitis
The Quarterly Journal of Medicine
|November 1, 1988
Summary
Severe Streptococcus pyogenes Group A infections caused septic scarlet fever and cellulitis in three healthy adults. Despite prompt antibiotic treatment, two patients died, highlighting a rare and aggressive post-antibiotic era presentation.
Area of Science:
- Infectious Diseases
- Bacteriology
- Clinical Medicine
Background:
- Streptococcus pyogenes (Group A Streptococcus) is a significant human pathogen.
- Scarlet fever and cellulitis are common Streptococcus pyogenes infections.
- Septic presentations are typically associated with specific risk factors.
Observation:
- Three healthy young adults presented with severe cellulitis.
- The cellulitis was associated with scarlet fever and signs of severe toxaemia.
- Blood cultures were positive for Streptococcus pyogenes Group A (serotype M1/T1/OF-).
Findings:
- Two of the three patients experienced fatal outcomes despite prompt antibiotic therapy.
- This represents a rare and aggressive clinical presentation of Streptococcus pyogenes infection.
- Such severe cases of cellulitis with scarlet fever, toxaemia, and septicaemia are unreported in the post-antibiotic era.
Implications:
- This case series underscores the potential for severe, life-threatening Streptococcus pyogenes infections even in healthy individuals.
- It highlights the need for heightened clinical suspicion for aggressive disease in patients presenting with cellulitis and scarlet fever.
- Further research into the virulence factors of specific Streptococcus pyogenes strains (e.g., M1/T1/OF-) may be warranted.
