Insights

Group A Streptococcus central nervous system infections in children are rare but increasing. This study found a significant rise in cases, with many requiring intensive care and some experiencing long-term effects or death.

Area of Science:

  • Pediatric Infectious Diseases
  • Neurology
  • Microbiology

Background:

  • Group A Streptococcus (GAS) is a common pathogen, typically causing pharyngitis or skin infections.
  • Central nervous system (CNS) infections are uncommon but serious complications of GAS.
  • Recent trends in pediatric CNS infections due to GAS require investigation.

Purpose of the Study:

  • To analyze the incidence and characteristics of CNS infections caused by GAS in children.
  • To identify trends and risk factors associated with these rare infections.
  • To report clinical outcomes, including sequelae and mortality.

Main Methods:

  • A multicenter retrospective study was conducted across 52 hospitals in Spain.
  • Data were collected from 2019 to 2023, identifying pediatric cases of CNS infections due to GAS.
  • Statistical analysis was performed to assess trends and significance.

Main Results:

  • A total of 32 pediatric cases of GAS CNS infections were identified.
  • A significant increase in incidence was observed from October 2022 onwards (1.1% to 5.9%, P = 0.002).
  • Half of the patients required pediatric intensive care unit (PICU) admission, 12.5% had sequelae, and the mortality rate was 6.2%. Mastoiditis was the most common primary infection.

Conclusions:

  • Pediatric CNS infections caused by GAS, while rare, show an increasing trend.
  • These infections are associated with significant morbidity, including PICU admission and sequelae.
  • Prompt recognition and management are crucial given the potential for severe outcomes.
