Invasive group A streptococcal (GAS) infections in children increased in the latter half of the study. Primary varicella infection was the most common risk factor, with low mortality rates.

Area of Science:

  • Pediatric Infectious Diseases
  • Bacteriology
  • Epidemiology

Background:

  • Invasive group A streptococcal (GAS) infections pose a significant threat to pediatric health.
  • Understanding the clinical spectrum and risk factors is crucial for effective management.

Purpose of the Study:

  • To review clinical features, laboratory findings, and risk factors of invasive GAS infections in children.
  • To analyze trends in invasive GAS infections over a nine-year period.

Main Methods:

  • Retrospective review of medical records of children with positive blood or sterile site cultures for group A beta-hemolytic streptococci.
  • Data analysis included patient demographics, clinical presentations, laboratory results, and outcomes.

Main Results:

  • Forty-one pediatric cases of invasive GAS were identified, with a higher incidence in the second half of the study (1995-1999).
  • Primary varicella infection was the most frequent predisposing factor (27%). Common manifestations included bacteremia, cellulitis, and osteomyelitis.
  • Leukocytosis was observed in 51% of patients; mortality was low (one fatality due to streptococcal toxic shock syndrome).

Conclusions:

  • A rise in invasive GAS diagnoses was noted in the latter study period, though overall bacteremia rates aligned with prior research.
  • Primary varicella infection remains a key risk factor for invasive GAS in children.
  • The low rates of toxic shock syndrome and fatalities in pediatric cases contrast with adult series.
