Syphilis is a chronic infectious disease with its prevalence being described since the 15 th century. Although its etiological agent and also the treatment measures are widely known, syphilis is still a great public health problem worldwide, mainly in countries with limited resources associated to low investments in health primary care. The aim of the present study was to analyze the trend and regional distribution of syphilis in Brazil between 2007 and 2017. This is an ecological study using secondary data from the Brazilian notification system. The Ministry of Health selected 100 municipalities which presented the worse outcomes related to syphilis from the 5,570 Brazilian municipalities as a target for a comprehensive project in order to tackle the prevalence of syphilis, called the "No Syphilis Project". These priority municipalities represent 57.7% of syphilis cases and about one third of the Brazilian population. They were compared with other 189 non-priority municipalities with more than 100 thousand inhabitants among the Brazilian regions (North, Northeast, Southeast, South and Center-West). Polynomial regression methods and Joinpoint analyses were used to analyze the trend, from which the Annual Average Percent Change (AACP) for each time period was calculated. There was a significant growth trend in all regions for the main three forms of syphilis (in pregnancy, congenital and acquired), especially in the South. The ratio between syphilis in pregnancy and congenital syphilis increased in both priority (AAPC: 8.54%; p<0.001) and non-priority municipalities (AAPC: 2.61%; p = 0.005), as well as in the regions, except the Center-West. High growth trends in syphilis prevalence were found in all municipalities, as well as all five regions between 2007 and 2017, showing that the challenge to reduce or even eliminate syphilis in Brazil is still difficult.
Acquired syphilis is a sexually transmitted infection that affects the general population and has been growing in recent years in many countries. A study was developed aiming to analyze the trends of acquired syphilis associated with sociodemographic aspects and primary health care in Brazil, in the period from 2011 to 2019. This study used secondary data from the national notification systems of the 5570 Brazilian cities and a database of 37,350 primary health care teams, as well as socioeconomic and municipal demographic indicators. The trends of acquired syphilis at the municipal level were calculated from the log-linear regression, crossing them with variables of primary health care and sociodemographic indicators. Finally, a multiple model was built from logistic regression. 724,310 cases of acquired syphilis have been reported. In primary care units, 47.8% had partial coverage and 74.1% had health teams with poor or regular scores. 52.6% had rapid test for syphilis partially available. Male and female condoms are available in 85.9% and 62.9% respectively and 54.4% had penicillin available in the health facility. The increase in trends of acquired syphilis was associated with better availability of the rapid test; lower availability of male condoms; lower availability of female condoms; lower availability of benzathine penicillin; partial coverage of the teams in primary health care; limited application of penicillin in primary health care; higher proportion of teams classified as Poor/Regular in primary health care; higher proportion of women aged 10 to 17 years who had children; higher HDI; higher proportion of people aged 15 to 24 years who do not study, do not work and are vulnerable; and population size with more than 100,000 inhabitants. The following variables remained in the multiple model: not all primary health care teams apply penicillin; higher proportion of primary health care teams with poor/regular scores; population size >100000 inhabitants; partially available female condom. Thus, the weakness of primary health care linked to population size may have favored the growth of the acquired syphilis epidemic in Brazilian cities.
OBJETIVO: Analisar o efeito da cobertura de testes rápidos na Atenção Básica sobre a taxa de detecção de sífilis em gestantes no Brasil, nos municípios com mais de 100 mil habitantes. MÉTODOS: A variável dependente foi a taxa de detecção de sífilis em gestantes entre os anos de 2012 e 2018. Como variáveis independentes principais, foram utilizados os métodos de aferição da cobertura de testes rápidos para sífilis na Atenção Básica e, como variáveis de ajuste, alguns indicadores de serviços de saúde e socioeconômicos. Optou-se por um modelo de regressão linear para dados em painel (panel data analysis), considerando o município como unidade de análise e ano como variável de tempo. RESULTADOS: Pelos resultados do modelo final, pode-se inferir que, para um determinado município, à medida que a taxa de testes rápidos aumenta em um ponto para cada mil nascidos vivos, a taxa de detecção de sífilis em gestantes aumenta em média 0,02 casos por mil nascidos vivos (p < 0,001). Esse valor está ajustado para cobertura de Saúde da Família, proporção de UBS por habitante, gastos per capita com saúde e Índice de Desenvolvimento Humano. CONCLUSÕES: Houve uma melhora substancial na quantidade de testes rápidos disponíveis, bem como, o aumento significativo de realização desses testes em gestantes, o que prediz o aumento das taxas de sífilis em gestantes. Contudo, uma hipótese preocupante é que a quantidade de testes realizados em gestantes no período analisado pode ter sido insuficiente para detectar o avanço da epidemia nessa população.
Objetivo: Avaliar os antecedentes epidemiológicos da parceria sexual dos casos de sífilis em gestante notificados no Sistema de Informação de Agravos de Notificação entre 2007 e 2019. Métodos: O estudo, do tipo ecológico, avaliou os dados referentes aos campos parceiro tratado concomitante à gestante, esquema de tratamento prescrito ao parceiro e motivo para o não tratamento do parceiro, contidos na ficha de notificação da sífilis em gestante. Foram incluídos no estudo todos os casos de sífilis em gestante notificados no Sistema de Informação de Agravos de Notificação no período de 2007 a 2019. Realizou-se uma análise de frequência dos campos selecionados. Resultados: No período analisado foram notificados 351.718 casos de sífilis em gestante no Brasil. Nos antecedentes epidemiológicos da parceria sexual, apenas 19,4% dos parceiros foram tratados concomitantemente às gestantes, tento a penicilina G benzatina como esquema de tratamento prescrito em 20,8% dos casos. A perda de contato com a gestante (6,4%) e outros motivos (8,6%) foram as principais razões para o não tratamento da parceria sexual. Todos os campos avaliados apresentaram menos de 50% de preenchimento, sendo motivo para o não tratamento do parceiro o campo com pior percentual de preenchimento. Conclusão: A baixa adesão ao tratamento do parceiro concomitante à gestante, além da baixa qualidade de preenchimento dos campos da ficha de notificação relacionados ao tema, reforça a importância de políticas voltadas à parceria sexual durante o pré-natal das gestantes com sífilis, para a redução efetiva dos casos de sífilis em gestante e congênita.
