Improving global estimates of syphilis in pregnancy by diagnostic test type: A systematic review and meta‐analysis

Abstract: Background“Probable active syphilis,” is defined as seroreactivity in both non-treponemal and treponemal tests. A correction factor of 65%, namely the proportion of pregnant women reactive in one syphilis test type that were likely reactive in the second, was applied to reported syphilis seropositivity data reported to WHO for global estimates of syphilis during pregnancy.ObjectivesTo identify more accurate correction factors based on test type reported.Search StrategyMedline search using: “Syphilis [Mesh] and… Show more

“…To estimate burden of active, transmissible syphilis, a standard syphilis test type correction factor was applied to adjust for syphilis test positivity that could be due to previously treated syphilis consistent with global CS estimation methods [1,17]. Lastly, we applied the previous estimate that untreated cases of maternal syphilis among women in ANC4 and not in ANC4, incurred a 52% risk of adverse birth outcomes (ABOs) and a 21% risk of stillbirth, to estimate the total number of ABOs and stillbirths that were due to CS and could have been avoided with maternal syphilis screening and treatment in 2016-2017 amongst these CD2030 countries [1,13,16].…”

“…[2][3][4][5] A forma mais comum de transmissão da sífilis ocorre pela via sexual, denominada sífilis adquirida, e verticalmente, a sífilis congênita, que passa da mãe infectada para o feto. 3,4,6 Existem ainda outras formas de transmissão, como a via indireta por objetos contaminados, tatuagem e por transfusão sanguínea. [6][7][8] A penicilina é o medicamento de primeira escolha para o tratamento da doença, por se tratar de um medicamento seguro e de baixo custo, além de seu uso ser permitido em gestantes, no caso de sífilis congêni-ta.…”
