We used data from the Groupe de pathologie infectieuse pédiatrique and Association clinique et thérapeutique infantile du Val-de-Marne (GPIP/ACTIV) National Survey of Bacterial Meningitis in children and the National Reference Center for Meningococci (CNRM) microbiological data to assess the potential impact of corticosteroids on the immediate management of invasive meningococcal disease (IMD) associated with different genotypes, including highly pro-inflammatory strains of the ST-11 clonal complex (genotype ST-11). ⋯ This study indicates that in the absence of corticosteroids, higher mortality in invasive meningococcal disease is associated with the ST-11 clonal complex strains. This suggests a possible positive effect of corticosteroid therapy depending on the genotype of the strain involved.
