Meningite por Haemophilus influenzae tipo b em cidades do estado do Paraná, Brasil

Abstract: Objective: during the second half of 1996, the municipalities of Londrina and Curitiba (State of Paraná, Brazil) included Haemophilus influenzae type b (Hib) vaccine into their routine vaccination regimen, approximately 30 months before its introduction into the National Immunization Program. The present study aimed at verifying the incidence of meningitis caused by Hib among children in Londrina, Curitiba, and in the remaining municipalities of the State, before and after the introduction of this vaccine into… Show more

“…In Curitiba, southern Brazil, the incidence of meningitis dropped from 35.5 to 9.7x10 5 (72% reduction), one year after the introduction of the vaccine. 13 In Salvador, northeastern Brazil, similar results were found (69% reduction) after the first year of vaccination. 12 There was a significant reduction in the number of probable acute bacterial meningitis (pABM) cases in the post-vaccine period, most likely due to the implementation of the surveillance system as well as to the accuracy of diagnostic tests.…”

“…6 The Hib vaccine was incorporated into the national immunization program (PNI) in mid 1999, and publications addressing the impact of vaccination are still scarce. 12,13 The present study is aimed at identifying the impact of Hib vaccination on the incidence of meningitides among underfives in the State of Goiás, in Central Brazil, two years after the introduction of the conjugate vaccine.…”

“…O predomínio do sexo masculino é mais evidente nos levantamentos de sepse e MB durante o período neonatal, particularmente quando causada por bacilos gram-negativos, em relação aos cocos gram-positivos. Este fato sugere a participação de uma base genética, ligada ao cromossomo X, na suscetibilidade à infecção; entretanto, outros fatores devem ser também importantes, pois o predomínio diminui muito ou desaparece após o período neonatal 16 e, dos três agentes mais comuns de MB em lactentes, apenas o Hib parece predominar no sexo masculino 13,20,21 .…”

“…São o Haemophilus influenzae b (Hib), a Neisseria meningitidis (meningococo) e o Streptococcus pneumoniae (pneumococo). A importância relativa de cada um deles varia de acordo com a área geográfica, com a situação endêmica no momento do estudo 4,5 e, mais recentemente, com a porcentagem das crianças menores de 5 anos vacinadas contra a infecção pelo Hib [7][8][9][10][11][12][13] .…”

“…Dados de vigilância nesses países detectaram declínio superior a 80% na meningite por Hib logo após a introdução da vacina 14,26,29,33 . Na América Latina, avaliações do impacto da vacinação nas meningites foram realizadas em Cuba, Colômbia, Uruguai, Chile e Brasil 31 , mostrando que as taxas de incidência de meningite por Hib no período pós-vacinal declinaram de 40 a 95%, comparadas ao período pré-vacinação, conforme mostrado na Tabela 1 22,[34][35][36][37][38][39][40][41][42] .…”
