Abstract

Purpose
Group A streptococcus (GAS) is a common pathogen in pediatric patients and often causes acute pharyngotonsillitis and skin and soft tissue infections. In addition, bacteremia with significant morbidity and mortality can also occur. This study was conducted to describe the clinical manifestations and treatment outcomes of pediatric GAS bacteremia patients in Korea.
Methods
This was a single-center, retrospective study. From January 2000 to December 2016, pediatric patients aged ≤18 years with GAS bacteremia were studied. Clinical manifestations, underlying diseases, intensive care unit stay, and antibiotic susceptibility were evaluated.
Results
During the study period, 19 patients had GAS bacteremia. Ten (53%) were male, and the median age was 7.4 years (range, 0.3–17.4 years). Fourteen (74%) had chronic underlying diseases. Five (26%) were immunocompromised (leukemia and chronic kidney disease). Eight (42%) had lymphatic or vascular malformations, of which seven had lesions with signs of inflammation. Three (16%) developed pneumonia, and two of them received ventilator care. The 30-day mortality rate was 6% (1/19), and the cause of death was bacteremic pneumonia. All GAS isolates were sensitive to penicillin. Fifteen (79%) were sensitive to both erythromycin and clindamycin.
Conclusions
This study identified various clinical manifestations of GAS bacteremia. GAS should be considered as a potential pathogen that can cause bacteremia and result in a serious clinical course.
