RESUMO

Objetivos:

Avaliar o impacto global, direto, indireto e a tendência da duração de proteção da vacinação contra o Haemophilus influenzae tipo b (Hib), no estado de São Paulo (ESP) e no município de São Paulo (MSP), na população de 0 - 59 meses, comparando os períodos pré-vacinal (1996 - 1998) e pós-vacinal (2001 - 2009).

Métodos:

estudo com componente descritivo e de cunho analítico, retrospectivo. A população de estudo incluiu os menores de cinco anos residentes no ESP e no MSP. Adotou-se como definição de caso confirmado o menor de cinco anos identificado como positivo para o Hib em cultura e/ou contraimunoeletroforese e/ou látex e/ou RT-PCR, em amostra de LCR e sangue, e/ou vínculo epidemiológico. Os dados foram obtidos a partir do SINAN, SIGH-Web Instituto Adolfo Lutz e Fundação IBGE. As variáveis de estudo incluíram as demográficas, clínicas e relativas ao agente, apresentadas em séries temporais e períodos estabelecidos para parametrização e comparabilidade. O parâmetro das avaliações de impacto foi a magnitude da variação da incidência de meningite causada pelo Hib. Para cada estimativa de impacto construiu-se um Intervalo de Confiança (IC) de 95 por cento a partir do cálculo de Risco Relativo (RR). As estimativas do risco relativo (RR) e os respectivos intervalos de 95 por cento de confiança foram analisados utilizando-se o software R.

Resultados:

nos períodos considerados, foram descritos 1.561 casos confirmados de meningites por Hib no ESP, sendo 27,16 por cento (424/1.561) no MSP, e 80,78 por cento (1.261/1.561) dos casos foram registrados em menores de cinco anos. A maioria dos casos foi confirmada por cultura, com percentual médio de 65 por cento no ESP e 66 por cento no MSP. As taxas médias de incidência de meningites por Hib mais significativas no período pré-vacinal verificaram-se nos menores de um ano (30,56/105- ESP; 32,06/105 - MSP), considerada a faixa etária de maior risco de adoecimento...
ABSTRACT

Objectives:

To evaluate global impact, direct and indirect, as well as the tendency of the duration of vaccine protection against Haemophilus influenzae type b (Hib) in the state of São Paulo (ESP) and in the city of São Paulo (MSP), amongst the population between 0-59 months of age during the periods pre-vaccine (1996-1998) and post vaccine (2001-2009).

Methods:

a retrospective study with a descriptive component and with analytic venue. Studied population included children under five years old, dwelling in ESP and MSP. Criteria adopted as definition of confirmed case was child under five years of age identified as positive for Hib in culture and/or counterimmunelectroforesis and/or latex and/or RT/PCR, in LCR sample and blood. and/or epidemiologic link. Data were obtained from the SINAN, SIGH-Web Instituto Adolfo Lutz and IBGE Foundation. Variables under study included socio-demographic and clinical ones, and those related to the agent; they were presented in temporal series and periods established in order to allow parametric and comparison. Impact evaluation was established upon the variation of incidence magnitude of meningitis caused by Hib. For each impact estimate a Confidence Interval (IC) of 95 per cent from the calculus of Relative Risk (RR). Estimates of relative risk (RR) and the respective intervals of 95 per cent confidence were analyzed employing the R software.

Results:

During the analyzed periods 1561 confirmed cases of meningitis caused by Hib were described in the state of São Paulo, 27.16 per cent of which (424/1561) in MSP; 80.78 per cent (1261/1561) of the registered cases occurred in children under five years of age. The majority of the cases were confirmed by culture, with an average percentage of 65 per cent in ESP and 66 per cent in MSP...
