Notificações de sífilis gestacional e congênita: uma análise epidemiológica

Abstract

Syphilis is an infectious disease that remains as one of the major reporting aggravations to be addressed globally. In the maternal-infant context it is related to deleterious effects from the vertical transmission and exposes the mother-child binomial to risks such as abortion and perinatal death. Thus, effective actions to control the disease must be performed in prenatal care, in a timely manner, to ensure the prevention of the congenital form of the disease. In this sense, this research aims to analyze the reports of gestational and congenital syphilis and the factors related to vertical transmission. This is a cross-sectional, epidemiological, epidemiological approach to secondary data, conducted in 2016. The sample was composed of eligibility criteria and totaled 129 reports of syphilis in pregnant women and 132 reports for congenital syphilis in the period Between June 2011 and December 2015, in the Municipality of Natal / RN. Data collection occurred between May and August through the Database of the Notification of Injury Information System. Data were analyzed by descriptive and inferential statistics. The Chi-square, T-Student, and Fisher tests were used to verify the associations between the variables of interest. The research received a favorable opinion by the Ethics Committee of the Federal University of Rio Grande do Norte under number 1,449,134 and Certificate of Presentation for Ethical Appraisal 53305315.3.0000.5537. In the period under investigation, there was an increase in reported cases in the year 2012. The registered maternal profile indicates women with a mean age of 24.78 years, browns (70.5%), living in the urban area (95.3%) of the Municipality from Natal. The prenatal analysis identified a predominance of maternal diagnosis in the third gestational trimester (69%) and presence of non-treponemal reactive tests in 94.6% of the women at the time of delivery. Regarding maternal treatment, only 1.6% of these women were registered with an adequate treatment regimen and 16.3% of the partners were treated concomitantly with the pregnant women. In the outcomes related to the children, 78.8% were registered as asymptomatic, however, this variable presented statistical significance when related to the titration of the non-treponemal maternal test and to the pre-delivery treatment. In the spatial analysis by geo - referencing, the predominance of cases in Quintas and Felipe Camarão neighborhoods, both assisted by the Sanitary District West of the municipality, was identified. The results point, moreover, to important gaps in the epidemiological surveillance processes regarding the filling of notifications regarding unknown and blank information. The analysis of the notification of gestational and congenital syphilis made it possible to conclude that vertical transmission was related to loss of diagnostic and therapeutic opportunities. The development of strategies for early detection and adherence to treatment of the disease should be adopted, with a view to strengthening care and breaking down the vertical syphilis transmission chain. The need for professional qualification for notification of the disease and extension in the provision of information to epidemiological surveillance is emphasized, in order to allow the continuity of the analysis to the disease.
