Serious group A streptococcal diseases in children
Insights
Group A Streptococcus infections can be severe in children. Patients without underlying health issues had a higher survival rate (93%) compared to those with pre-existing conditions (54%).
Area of Science:
- Pediatrics
- Infectious Diseases
- Microbiology
Background:
- Streptococcus pyogenes (Group A Streptococcus) is a significant bacterial pathogen.
- Group A Streptococcus can cause a range of severe infections, including septicemia, meningitis, and pneumonia.
Purpose of the Study:
- To describe the clinical characteristics and outcomes of invasive Group A Streptococcus infections in pediatric patients.
- To identify factors influencing survival in children with these infections.
Main Methods:
- Retrospective case series describing 40 pediatric patients diagnosed with invasive Group A Streptococcus infections.
- Analysis of patient demographics, clinical presentations, underlying conditions, treatments, and outcomes.
Main Results:
- Overall survival rate was 71% (25/27) in patients without underlying disease versus 54% (7/13) in those with underlying disease.
- Nine survivors without prior health issues experienced prolonged and complicated illness courses.
- Septicemia without a clear source was observed in some severe cases.
Conclusions:
- Group A Streptococcus can cause severe, rapidly progressive infections in children, even with antibiotic sensitivity.
- Underlying health conditions significantly impact survival rates.
- Prompt diagnosis and management are crucial for improving outcomes in invasive streptococcal infections.
Abstract:
The illnesses of 40 patients with diagnoses of septicemia, cellulitis with bacteremia, pneumonia empyema, and meningitis caused by Streptococcus pyogenes, Group A, are described. Twenty-five of 27 patients (93%) without underlying disease survived, whereas only seven of 13 children (54%) with underlying disease survived. Nine of the 25 patients who were otherwise normal and who survived these infections had prolonged, complicated illnesses. Four of these patients, and one who died, had septicemia without a focus of infection at the time of admission. Streptococcus pyogenes, Group A, although very sensitive to penicillin G and other antibiotics, can cause both severe and rapidly progressive disease in children.
