Serogroup B meningococcal disease is the commonest cause of meningitis and septicaemia in high-income countries. Assessment of new serogroup B meningococcal vaccines is hampered by a scarcity of data on the burden of disease in survivors. We aimed to estimate the disease burden in children having survived serogroup B meningococcal disease.
In this case-control study, we recruited children from the UK National Meningococcal Registry between May, 2008, and September, 2010. Eligible children were survivors who had had serogroup B meningococcal disease confirmed by culture or PCR and were aged 1 month to 13 years at disease. Age-matched and sex-matched controls were recruited through the family doctor of the children who had the meningococcal disease. Physical, psychological, neurocognitive, and educational outcomes were assessed through a standardised interview with validated instruments. We did matched analyses using generalised estimating equations (GEE). Researchers were masked to the children's serogroup B meningococcal status.
Of the 537 children who had serogroup B meningococcal disease and were available for recruitment, 245 were assessed. 328 controls were also recruited; 221 controls were matched with a case and 107 were additional unmatched controls. The mean age was 6·5 (SD 2·8) years in children with serogroup B meningococcal disease and 6·9 (2·9) in controls. In the full sample, children who had serogroup B meningococcal disease were more likely than controls to have bilateral sensorineural hearing loss of 40 dB or more (unmatched 11 [5%] of 232 children with meningococcal disease vs three [<1%] of 318 controls; matched odds ratio [OR] 4·8, 95% CI 1·3 to 17·4, p=0·02), lower full-scale IQ (matched mean 99·5 for children with meningococcal disease and 107·2 for controls; matched coefficient -7·6, 95% CI -9·9 to -5·4, p<0·0001), and psychological disorders (61 [26%] of 235 children with meningococcal disease vs 33 (10%) of 322 controls; matched full sample OR 2·6, 1·6 to 4·2, p<0·0001). Disabling amputations were noted in three (1%) of 239 children who had serogroup B meningococcal disease compared with none of the 322 controls. Children with meningococcal disease were also more likely to have deficits in executive function and multiple aspects of memory. Deficits were identified in 87 (36%) of 244 children with serogroup B meningococcal disease and 49 (15%) of 328 controls (matched OR 2·7, 1·8 to 4·1, p<0·0001). Major disabling deficits were identified in 21 (9%) of 244 children with meningococcal disease compared with six (2%) of 328 controls (matched OR 5·0, 2·0 to 12·6, p=0·001). No significant differences were noted in attentional function or post-traumatic stress disorder between children with serogroup B meningococcal disease and controls.
Most children survive serogroup B meningococcal disease without major sequelae. However, about a tenth have major disabling deficits and more than a third have one or more deficits in physical, cognitive, and psychological functioning, with the additional burden of memory deficits and executive function problems. These findings should help to guide assessments of new vaccines and suggest that all survivors of serogroup B meningococcal disease should be screened for psychological disorders and cognitive deficits in addition to hearing loss.

[Show abstract][Hide abstract] ABSTRACT: Incidence of invasive meningococcal disease is low in Germany at 0.5 cases/100,000 inhabitants. Serogroup B (MenB) is most common, causing 70% of cases, with highest incidence in infants (5.9/100,000). In 2013, a MenB vaccine was licensed in Europe. To assess pediatricians’ attitudes towards MenB vaccination and its potential use in Germany we conducted a nationwide cross-sectional survey among 5677 pediatricians. Of 3107 participants (response: 55%), 79.1% would recommend a MenB vaccination to parents, with 66.7% favoring a schedule at 6, 8 and 12 months over 2, 3, 4 and 12 months (13.4%). Administration separately from other vaccines was preferred (63.2%); 38.5% feared that a recommendation would lead to refusal of other recommended vaccinations. In conclusion, pediatricians showed distinct preferences regarding possible integration of MenB vaccination into the existent immunization schedule. As physicians play a crucial role in the implementation, findings will be useful in decision-making regarding potential introduction.
