Resumo: Meningitis is a notifiable disease with high morbidity and mortality, whose main etiology is infectious. It affects people of any age, and particularly children under five years of age. Given this context, this cross-sectional study sought to evaluate the epidemiology of meningitis in children and adolescents in the state of Bahia, Brazil, between 2007 and 2018. Data was collected from the Ministry of Health Information System of Notifiable Diseases (SINAN) database and included all patients aged 0 to 19 years with confirmed meningitis. Macroregion/municipality, gender, age, race/ethnicity, seasonality, etiology, diagnostic methods, and evolution/outcome were the variables studied. A total of 152,422 cases were identified in Brazil, with 8,579 cases in Bahia (5.6% of the country, 27.7% of the Northeast), more frequent in 2007 (18.3%), and decreasing between 2013-2018. The capital, Salvador, accounted for 72.6% of the state’s cases. Male gender (1.5:1), age between five and nine years (28.2%), brown (53.4%) and viral aetiology (57.8%), occurring latter in spring, predominated. Meningococci (9.1%) and pneumococci (3.1%) predominated as isolated agents, while 14% were classified as ‘other bacteria.’ Isolation of meningococcal serogroups (52.1%): A (0.25%), B (12.40%), C (81%), Y (0.25%), W135 (5.5%) and 29E (0.7%). The main diagnostic method was chemocytological. Main outcomes included hospital discharge (83.6%), and death by meningitis (6.6%) and other causes (1.1%). In Bahia, infection by meningitis showed a sharp decline between 2013 and 2017, which may result from vaccination routine; however, the methodology used does not allow us to infer this relationship. Serogroups C and B predominated, but 69% (22/32) of Northeastern cases by serogroup W135 occurred in Bahia.

Estas enfermedades acometen a personas de cualquier edad, aunque son más frecuentes en individuos con menos de 5 años de edad. El objetivo de este estudio fue evaluar la epidemiología de las meningitis en niños y adolescentes en el estado de Bahía (Brasil) entre 2007-2018. Se trata de un estudio de corte transversal, que analizó datos de la base digital del Sistema de Información de Agravios de Notificación del Ministerio de Salud (SINAN) e incluyó a todos los pacientes de 0 a 19 años con meningitis confirmada en Bahía, entre 2007-2018. Las variables estudiadas fueron municipio/macrorregión, sexo, edad, raza, estacionalidad, etiología, métodos diagnósticos y evolución/desenlace. Se produjeron 152.422 casos en Brasil, de los cuales 8.579 fueron en Bahía (5,6% del país, 27,7% del Nordeste), los más frecuentes en 2007 (18,3%), con descenso entre 2013-2018. La capital de Bahía, Salvador, cubrió el 72,6% de los casos del estado. Hubo un mayor predominio en el sexo masculino (1,5:1), con edad entre los 5 y los 9 años (28,2%), raza parda (53,4%) y etiología viral (57,8%), esta última con mayor prevalencia en la primavera. Los agentes aislados fueron meningococos (9,1%), neumococos (3,1%) y “otras bacterias” (14%). El aislamiento de los serogrupos del meningococo (52,1%): A (0,25%), B (12,40%), C (81%), Y (0,25%), W135 (5,5%) y 29E (0,7%). El método diagnóstico principal fue el quimiocitológico. Los desfechos fueron alta hospitalaria (83,6%), muertes por meningitis (6,6%) y otras causas (1,1%). La meningitis en Bahía declinó acentuadamente entre 2013 y 2017, lo que puede apuntar un impacto de la vacunación de rutina, pero la metodología utilizada no permite inferir esa relación. Los serogrupos C y B fueron los más frecuentes, sin embargo, cabe destacar que el 69% (22/32) de los casos nordestinos por el W135 ocurrieron en Bahía.Meningites são doenças de notificação compulsória com alta morbimortalidade, cuja principal etiologia é infecciosa.

A capital, Salvador, abrangeu 72,6% dos casos do estado. Predominaram: sexo masculino (razão 1,5:1), idade entre cinco e nove anos (28,2%), raça parda (53,4%) e etiologia viral (57,8%), esta última com predomínio na primavera. Agentes isolados: meningococos (9,1%), pneumococos (3,1%) e 14% foram “outras bactérias”. Isolamento de sorogrupos do meningococo (52,1%): A (0,25%), B (12,40%), C (81%), Y (0,25%), W135 (5,5%) e 29E (0,7%). O método diagnóstico principal foi o quimiocitológico. Desfechos: alta hospitalar (83,6%), óbitos por meningite (6,6%), por outras causas (1,1%). A meningite na Bahia declinou acentuadamente entre 2013 e 2017, podendo indicar uma consequência da vacinação de rotina, entretanto, a metodologia utilizada não permite confirmar essa relação.
