Temporal distribution of gestational syphilis cases in metropolitan area in Brazilian Amazon

Objective: This study aimed to know the occurrence of gestational syphilis cases in a municipality in the Brazilian Amazon from a historical series of cases. Method: A descriptive cross-sectional analysis with a quantitative approach was carried out from the official gestational syphilis notifications between 2015-2019, in the municipality of Ananindeua, state of Pará, northern Brazil. Results: Notified 421 cases of syphilis in pregnant women in the given period, with prevalence of cases between 2015 and 2016 (43%). In socioeconomic aspects, more than half of the mothers were aged 20-29 years (57%), with schooling below the average level (77.6%), brown race (85.5%). It can also be observed that the majority had the diagnosis notified in the third trimester of pregnancy (77.1%), with the primary syphilis classification (50.3%), being treated with penicillin (79.0%). An analysis of the correlation of congenital syphilis cases of the same period with prenatal performance was made, observing that most mothers performed prenatal (78.6%), but that the moment of diagnosis was the delivery (51.2%), and those who received treatment during pregnancy was inadequate (56.1%), with predominance of untreated partners (61.8%). Conclusion: The study brought information of a serious public health problem in the metropolitan areas of the Brazilian Amazon, with a profile compatible with what is also found elsewhere in the world. Although there is a prenatal care network, there is a lack of early adherence, adequate guidance, broader treatment including partners, and permanent maintenance of preventive actions and therapeutic inputs ensured.
