BACKGROUND: To characterize the electrophysiologic and neurological outcomes of pediatric patients with central nervous system infections secondary to Streptococcus anginosus group (SAG).
METHODS: We report a retrospective case series of 15 pediatric patients admitted to the pediatric intensive care unit (PICU) with central nervous system infections caused by SAG.
RESULTS: The population was healthy with no significant comorbidities before presentation. Prodromal symptoms had an acute onset (less than four weeks), with most patients experiencing fever (93%), headache (87%), and fatigue (87%). Fourteen patients (93%) had subdural or epidural empyema, while one (7%) had ventriculitis. Nine patients (60%) underwent continuous electroencephalography recording. Seven patients (47%) had seizures, with three patients (20%) having subclinical seizures only. One patient (7%) developed epilepsy. Five patients (33%) had mild to moderate residual deficits on neurological examination at discharge. Neuropsychologic testing revealed emotional dysregulation (e.g., emotional reactivity, anxiety, depression), attention deficits, and difficulty with working memory.
CONCLUSIONS: Among our cohort, patients were previously healthy with acute onset of nonspecific symptoms. Hospitalization was typically complicated by intracranial abscesses and seizures; the prognosis was favorable, with only one third of patients experiencing neurological deficits at discharge. Neuropsychologic data showed notable psychological deficits following PICU admission.
