Objectives:
We report on the incidence, clinical characteristics, and bacterial genotype of group A streptococcal (GAS) meningitis in the Netherlands.
Methods:
We assessed the incidence, clinical characteristics, and outcome of patients with GAS meningitis from a nationwide cohort study of adults with community-acquired bacterial meningitis in the Netherlands from 2006 to 2013.
Results:
GAS was identified in 26 of 1322 patients with community-acquired bacterial meningitis (2%); 9 cases (35%) occurred in the first four months of 2013. GAS meningitis was often preceded by otitis or sinusitis (24 of 26 [92%]) and a high proportion of patients developed complications during clinical course (19 of 26 [73%]). Subdural empyema occurred in 8 of 26 patients (35%). Nine patients underwent mastoidectomy and in 5 patients neurosurgical evacuation of the subdural empyema was performed. Five of 26 patients (19%) died and 11 of 21 surviving patient had neurologic sequelae (52%). Infection with the emm1 and cc28 GAS genotype was associated with subdural empyema (both 4 of 6 [67%] vs. 2 of 14 [14%]; P = 0.037).
Conclusions:
GAS meningitis is an uncommon but severe disease. Patients are at risk for empyema, which is associated with infection with the emm1 and cc28 genotype.
