O objetivo deste estudo foi analisar a associação entre as taxas de incidência da sífilis gestacional e da sífilis congênita e a cobertura de pré-natal no período de 2007 a 2017 no Estado da Bahia, Brasil. Trata-se de um estudo ecológico e longitudinal, cujas unidades de análise foram os municípios do Estado da Bahia. Foram utilizados dados secundários, obtidos nas bases de dados dos Sistemas de Informação em Saúde. A análise da associação entre as taxas de incidência e a cobertura do pré-natal foi realizada por meio de dados em painel, utilizando o modelo fixo com resposta binomial negativa, controlada pelas variáveis socioeconômica, demográfica e de tempo. Nas análises multivariadas, a cobertura de pré-natal apresentou associação positiva estatisticamente significante com a taxa de incidência de sífilis gestacional, mas não foi observada associação com a taxa de incidência de sífilis congênita. Tendo como referência o grupo de municípios com cobertura pré-natal < 45%, a taxa de incidência de sífilis gestacional aumentou em 22% e 25%, respectivamente nos municípios com cobertura de pré-natal entre 45%-64,9% (RR = 1,22; IC95%: 1,11-1,33) e ≥ 65% (RR = 1,25; IC95%: 1,10-1,43). Os achados do estudo indicam que, embora a ampliação da cobertura de atenção pré-natal nos municípios baianos tenha contribuído para a melhoria da detecção dos casos de sífilis gestacional, não houve impacto na redução da taxa de incidência de sífilis congênita. A assistência pré-natal prestada apresenta limitações, que devem ser alvo de intervenções que promovam a prevenção e o bloqueio da transmissão vertical da sífilis.

Objetivo: Descrever a completude e as características das notificações de sífilis gestacional e congênita no estado da Bahia, Brasil, no período 2007-2017. Métodos: Estudo ecológico, com dados do Sistema de Informação de Agravos de Notificação (Sinan). Foram calculadas as taxas de incidência para a Bahia e suas macrorregiões de saúde, e o percentual da completude dos dados. Resultados: Foram identificados 15.050 casos de sífilis gestacional e 7.812 de sífilis congênita, no período analisado. A taxa de incidência variou de 1,3 para 15,1 casos em gestantes/1 mil nascidos vivos, e de 0,5 para 6,7 casos em menores de 1 ano/1 mil nascidos vivos. A completude da 'classificação clínica' dos casos de sífilis gestacional apresentou preenchimento variável, entre 58,2% e 67,2%, entre 2007 e 2017. Conclusão: Evidenciou-se aumento nas taxas de incidência, falha no preenchimento das notificações e necessidade de implementação de uma rotina de avaliação da qualidade das informações.

OBJECTIVE: To evaluate the quality of information on gestational syphilis (GS) and congenital syphilis (CS) on the Sistema de Informação de Agravos de Notificação (SINAN-Syphilis Brazil – Notifiable Diseases Information System) by compiling and validating completeness indicators between 2007 and 2018. METHODS: Overall, care, and socioeconomic completeness scores were compiled based on selected variables, by using ad hoc weights assigned by experts. The completeness scores were analysed, considering the region and area of residence, the pregnant woman’s race/colour, and the year of case notification. Pearson’s correlation coefficients were used to validate the scores obtained by the weighted average method, compared with the values obtained by principal component analysis (PCA). RESULTS: Most selected variables presented a good or excellent degree of completeness for GS and CS, except for clinical classification, pregnant woman’s level of education, partner’s treatment, and child’s race/colour, which were classified as poor or very poor. The overall (89.93% versus 89.69%) and socioeconomic (88.71% versus 88.24%) completeness scores for GS and CS, respectively, were classified as regular, whereas the care score (GS-90.88%, and CS-90.72%) was good, despite improvements over time. Differences in the overall, care and socioeconomic completeness scores according to region, area of residence, and ethnic-racial groups were reported for syphilis notifications. The completeness scores estimated by the weighted average method and PCA showed a strong linear correlation (> 0.90). CONCLUSION: The completeness of GS and CS notifications has been improving in recent years, highlighting the variables that form the care score, compared with the socioeconomic scores, despite differences between regions, area of residence, and ethnic-racial groups. The weighted average was a viable methodological alternative easily operationalised to estimate data completeness scores, allowing routine monitoring of the completeness of gestational and congenital syphilis records.

Background Syphilis is among the most common sexually transmitted infections worldwide. When it occurs during pregnancy, it can seriously affect the fetus and newborn`s health. The scarcity of studies on maternal and congenital syphilis in Indigenous Peoples remains an obstacle to its control in these populations. This study aimed to explore the breadth of the literature, map updated evidence, and identify knowledge gaps on maternal and congenital syphilis in Indigenous Peoples worldwide. Methods We conducted a Scoping review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses - Extension for Scoping Reviews. In March 2021, we collected data through a priority search on PubMed, Web of Science, Embase, and SciELO. Results The strategy yielded 24 studies for analysis. Data in the articles were collected from 1989 to 2020, half from 2015 onwards. Studies were in Oceania and the Americas, mainly in South America (66.7%), particularly in Brazil (50.0%). The topics assessed were Data quality related to maternal and congenital syphilis (20.8%); Diagnosis, provision, access, and use of health services (62.5%); Disease frequency and health inequities (54.2%); Determinants of maternal syphilis and congenital syphilis (20.8%); and Outcomes of maternal and congenital syphilis in the fetus (20.8%). The results show that the available literature on maternal and congenital syphilis is sparse and concentrated in some geographic areas; the frequency of these diseases in Indigenous Peoples varies but is generally higher than in the non-indigenous counterparts; the quality of surveillance data and health information systems is poor; multiple healthcare barriers exist; and the diversity of terms to identify Indigenous Peoples is a challenge to mapping scientific outputs on Indigenous Peoples’ health. Conclusions Maternal and congenital syphilis in Indigenous Peoples is a double-neglected condition and research in this area should be given the priority and encouragement it deserves globally. Reliable data and improving access to health care are needed to reduce the burden of syphilis and correctly inform policies and health services response to mitigate ethnic-racial inequalities in maternal and congenital syphilis.
