Abstract

Insights

Group A Streptococcus (GAS) meningitis is a severe infection. Key risk factors include varicella, soft tissue infections, and CSF leaks, with young children and hematogenic spread posing higher mortality risks.

Area of Science:

  • Pediatric Infectious Diseases
  • Bacterial Meningitis Research
  • Epidemiology of Streptococcal Infections

Background:

  • Group A Streptococcus (GAS) meningitis is a critical illness with a high mortality rate.
  • Understanding of GAS meningitis remains limited despite its increasing prevalence.

Purpose of the Study:

  • To enhance comprehension of GAS meningitis through a comprehensive review.
  • To identify key risk factors, clinical presentations, and outcomes associated with GAS meningitis.

Main Methods:

  • A systematic literature review of PUBMED and EMBASE was conducted for GAS meningitis cases.
  • Included were case reports and series focusing on pediatric populations.
  • Data on demographics, risk factors, symptoms, treatments, outcomes, and emm types were extracted and summarized.

Main Results:

  • The review encompassed 263 cases of GAS meningitis.
  • Identified risk factors included prior varicella (9.9%), anatomical factors (11.1%), and extracranial infections (53.2%).
  • Infants commonly presented with soft tissue infections (34.5%), while older children (≥3 years) more frequently had ear/sinus infections (50.0%). The overall case fatality rate was 16.2%, with shock being the primary cause of death.

Conclusions:

  • Clinical indicators for GAS meningitis in children include a history of varicella, soft tissue infections, parameningeal infections, and CSF leaks.
  • Young children and cases involving hematogenic spread require vigilant monitoring for shock due to elevated mortality risk.
