ABSTRACT
This study aimed to describe the magnitude, mortality, and case-fatality rate from meningococcal disease and to investigate predictors of death from this cause in the city of São Paulo, Brazil, from 1986 to 2004, using unconditional multiple logistic regression. We analyzed 10,087 cases of meningococcal disease in the city. Mean annual mortality was 1.0/100,000 inhabitants, ranging from 0.2 to 1.8. Case-fatality was 20.5%, with major differences according to age, serogroup, and type of hospital. Predictors of death from meningococcal disease were age, especially the age brackets from one to two years and 40 years and older, and serogroup W. The results can contribute to the elaboration of public policies with a focus on the organization of hospital care and protocols to promote greater treatment effectiveness and application of vaccination strategies that decrease the incidence in groups at greatest risk of death from meningococcal disease.

O estudo objetiva descrever a magnitude, as características da mortalidade e da letalidade por doença meningocócica e investigar preditores de óbito por essa causa, no Município de São Paulo, Brasil, de 1986 a 2004. Utilizou-se a regressão logística múltipla não condicional para a investigação dos preditores de óbitos. Foram estudados 10.087 casos de doença meningocócica no município. A taxa anual média de mortalidade foi de 1,0/100 mil habitantes/ano, variando de 0,2 a 1,8; a letalidade foi de 20,5% com grandes diferenças segundo idade, sorogrupo e tipo de hospital. Os preditores de óbito por doença meningocócica foram idade, especialmente as faixas etárias de um a dois anos e de 40 anos ou mais e o sorogrupo W. Os resultados obtidos podem contribuir para a elaboração de políticas públicas com foco na organização da assistência hospitalar e elaboração de protocolos que promovam a maior efetividade do tratamento e a aplicação de estratégias de vacinação que diminuam a incidência nos grupos de maior risco para óbito por doença meningocócica.

Los objetivos fueron describir la magnitud y las características de la morbilidad y mortalidad por enfermedad meningocócica e investigar los predictores de muerte. Fueron estudiados 10.087 casos de enfermedad meningocócica ocurridos en São Paulo, entre 1986 y 2004. Los predictores de muerte por enfermedad meningocócica se investigaron por regresión logística no condicional. La tasa anual media de mortalidad por enfermedad meningocócica en el periodo del estudio fue de 1,0/100 mil habitantes/año, variando de 0,2 a 1,8, con distribución desigual, afectando fuertemente a los distritos más pobres. La letalidad fue de 20,5% con grandes diferencias según edad, serogrupo y tipo de hospital. Los principales predictores de muerte fueron la edad, especialmente, menores de dos años, y serogrupo W. Los resultados pueden contribuir a la elaboración de las políticas públicas con un enfoque en la organización de la atención hospitalaria y elaboración de protocolos que promuevan una mayor eficacia del tratamiento y la aplicación de las estrategias de vacunación para reducir la incidencia de los grupos con mayor riesgo de muerte por enfermedad meningocócica.
