Previous issue date: 2014-08-18 / Importance: Many efforts have ocurred in identify risk factors and causes of congenital syphilis (CS) persistence along years, and in many cases, the repetition of the condition in the same woman. In Rio Grande do Sul, there are no studies about the reincidence of CS, its causes and outcomes.
Objectives: To investigate the next pregnancies in women who already had syphilis in a previous pregnancy.
Methods: The study sample were women with obstetrical events ocurred in S?o Lucas Hospital (SLH) between may 1997 and december 2004. We included all patients with syphilis before or during pregnancy who had newborns, stillborns or abortions with CS, as patients correctly treated for syphilis before delivery and that had newborns without syphilis. The CS cases were defined according to the Brazilian Ministry of Health (appendix 1). The follow-up period for the subsequent pregnancies was until december 2011. The data were analised in program Epi Info 3.4, using the χ? test or Fisher exact test for associations, and Mann-Whitney-Wilcoxon test for comparison of medians. The level of significance was set at p < 0,05.
Results: We identified 450 women with positive tests for syphilis that had at least one obstetrical event in SLH between may 1997 and december 2004, within 166 had at least one more obstetrical event in the same hospital until december 2011.Cases of CS were 82% in the initial events and 68,5% in the subsequent s (OR 2,09, CI95% 1,3-3,3). Within patients with CS in the initial event, 72% had at least one more pregnancy with CS, against 56,6% of patiens without CS in the initial event(OR 1,97, CI95% 0,9-4,4).
Conclusions: Many cases of CS with adverse outcomes ocurred in the subsequent pregnancies, although less than in the initial events. It is suspected that more uninfected newborns may have been defined as cases of congenital syphilis in subsequent pregnancies, because of the lack of records of maternal history and the absence or inadequacy of prenatal care. It is important to increase surveillance on women who have already had one pregnancy with syphilis. / Import?ncia: Muitos esfor?os t?m ocorrido em identificar os fatores de risco e as causas da persist?ncia da s?filis cong?nita (SC) ao longo dos anos, e muitas vezes a repeti??o de casos em uma mesma mulher. No Rio Grande do Sul, ainda n?o existe um estudo sobre a reincid?ncia da SC, suas causas e seus desfechos.
Objetivos: Investigar as gesta??es subsequentes em mulheres que tiveram s?filis na gesta??o.
Material e m?todos: A popula??o de estudo foram as pacientes atendidas no Centro Obst?trico do HSL cujos eventos obst?tricos ocorreram entre maio de 1997 e dezembro de 2004. Foram inclu?das todas as pacientes que tiveram s?filis antes ou durante a gesta??o e tiveram rec?m-nascidos vivos, abortos ou natimortos com s?filis cong?nita, assim como pacientes adequadamente tratadas para s?filis antes do parto, que deram ? luz rec?m-nascidos vivos sem s?filis cong?nita. Os casos de s?filis cong?nita foram definidos conforme os crit?rios do Minist?rio da Sa?de (anexo 1). O levantamento das gesta??es subsequentes incluiu o per?odo at? dezembro de 2011. Os dados foram analisados no programa Epi Info 3.4, utilizando-se o teste de χ? ou teste exato de Fisher para associa??es, e o teste Mann-Whitney-Wilcoxon para compara??es de medianas. O n?vel de signific?ncia foi estabelecido como p < 0,05.
Resultados: Foram identificadas 450 mulheres com testes positivos para s?filis com pelo menos um evento obst?trico no HSL entre maio de 1997 e dezembro de 2004, das quais 166 tiveram pelo menos mais um evento subsequente no mesmo hospital at? dezembro de 2011. Os casos de SC foram de 82% nos eventos iniciais e 68,5% nos subsequentes (OR 2,09, IC95% 1,3-3,3). Entre as pacientes com SC no evento inicial, 72% tiveram pelo menos mais um evento com SC, contra 56,6% das pacientes sem SC no evento inicial (OR 1,97, CI95% 0,9-4,4).
Conclus?es: Ocorreram muitos de casos de SC com desfechos adversos nas gesta??es subsequentes, embora em menor n?mero do que nas iniciais. Suspeita-se que mais rec?m-nascidos n?o infectados possam ter sido definidos como casos de s?filis cong?nita nas gesta??es subsequentes, em virtude da falta de registros dos antecedentes maternos e da aus?ncia ou inadequa??o do acompanhamento pr?-natal. ? importante aumentar a vigil?ncia sobre as mulheres que j? tiveram uma gesta??o com s?filis.
