ABSTRACT

Objetivou-se levantar a prevalência de marcadores sorológicos da Hepatite B em usuários do Laboratório Central do Piauí-Brasil, no período de 2006 a 2009. Trata-se de um levantamento epidemiológico, descritivo, com coleta retrospectiva, realizado em 2010. Dos 69.377 exames analisados, foram diagnosticados 746 casos de Hepatite B aguda. A prevalência foi de 2,0% para o HBsAg, 55% Anti-HBs, 2,5% Anti-HBc IgM, 10% Anti-HBc Total, 48,5% HBeAg. Observou-se predominância do sexo masculino e da faixa etária de 20 a 39 anos nos resultados positivos. As prevalências dos marcadores sorológicos encontradas foram mais altas que as exibidas nos registros oficiais do Estado e Ministério da Saúde, sugerindo a necessidade de revisão dos bancos de dados para correção das inconsistências.


The study surveyed the prevalence of serum markers for Hepatitis B in users of Piauí State Central Laboratory between 2006 and 2009. This descriptive epidemiological study, with retrospective data collection, was conducted in 2010. In the 69,377 tests examined 746 cases of acute Hepatitis B infection were diagnosed. The prevalences were: HBsAg, 2.0%; Anti-HBs, 55%; Anti-HBc (IgM), 2.5%: Anti-HBc (Total), 10%; and HBeAg, 48.5%. Males and the 20-39 year age range predominated in the positive results. The prevalences of serum markers found were higher than those shown in official state and Ministry of Health records, suggesting the need to review the databases to correct shortcomings.

Se observó predominancia del sexo masculino y de la franja etaria de 20-39 años en los resultados positivos. La prevalencia de marcadores serológicos obtenidos fueron superiores a los indicados en las actas oficiales del Estado y Ministerio de la Salud, lo que sugiere la necesidad de revisar las bases de datos para corregir las inconsistencias.

ABSTRACT

The present paper reports a laboratory investigation performed between the years of 2000 and 2002 to stydy a virological surveillance program introduced in the state of Piauí to support an epidemiological survey of the disease. Dengue virus type 3 (DENV-3) existence in the state was detected in May 2002 when a high number of dengue cases due to DENV-1 and DENV-2 were reported. An assessment on the population knowledge about the disease and its transmission showed that almost 50 percent of the population were still unaware of the epidemiological features of dengue.
