Syphilis infection among homosexual men reporting contact with syphilis: a case control study.

ABSTRACT: High rates of syphilis have been reported among men who have sex with men (MSM) internationally. Guidelines recommend presumptive treatment of sexual contacts of individuals with syphilis at the point of care. The aim of this study was to determine the proportion who were infected with syphilis and the factors predictive of infection among men reporting contact with a man with syphilis.Contacts who were syphilis infected (cases) were compared with those who were uninfected (controls).This study was conducted at the main public sexually transmitted diseases clinic in Victoria, Australia.One hundred and seventy-two MSM presenting as sexual contacts of men with syphilis at a sexual health service in Melbourne, Australia, between July 2007 and October 2011 were assessed for syphilis.Proportion of MSM who are infected with syphilis and factors associated with infection.Of the 172 men who presented reporting contact with syphilis, 26 (15%, 95% CI 10 to 20%) had syphilis. One man had primary syphilis, 4 had secondary syphilis, while the remaining 21 had early latent syphilis. Infection was associated with unprotected anal sex over the prior 3 months (adjusted OR 6.1, 95% CI 1.4 to 26.8).One in seven men presenting as contacts of syphilis had syphilis infection, most of whom were latently infected. Contacts reporting recent unprotected anal sex were more likely to have syphilis.

Project description:BackgroundUntreated male partners are a critical source of maternal re-infection. Contact tracing is a good way to identify infection among partners and reduce risk of mother-to-child transmission related to maternal re-infection. This study aimed to analyze the current situation and related factors of contact tracing of syphilis-seropositive pregnant women and syphilis-infection among their male partners.MethodData of syphilis-seropositive pregnant women and their male partners attending clinic for syphilis-screening were obtained from the Shenzhen Program for Prevention of Congenital Syphilis. Contact tracing rate of syphilis-seropositive pregnant women and syphilis prevalence among male partners were counted, and related factors were also analyzed using a random-effects logistic regression model.ResultOf the 1299 syphilis-seropositive pregnant women, 74.1% (963/1299) had their male partners receiving syphilis-screening and 19.1% (184/963) of male partners were syphilis-infected. For pregnant women, being divorced (adjusted odds ratio [AOR] =0.39; 95%CI: 0.17-0.87), seeking for emergency services at their first antenatal clinics visits (AOR = 0.58; 95%CI: 0.44-0.77), reporting willingness to notify partner(AOR = 7.65; 95%CI: 4.69-12.49), multi-partners (AOR = 1.38; 95%CI:1.03-1.86) and having a history of drug abuse (AOR = 0.37; 95%CI: 0.14-1.00)were independently associated with successful contact tracing. For male partners, of minority ethnicity (AOR = 4.15; 95%CI: 1.66-10.34), age at first sex>20(AOR = 0.57; 95%CI: 0.37-0.87), reporting multi-partners (AOR = 1.60; 95%CI: 1.04-2.46), having a history of drug abuse (AOR = 4.07; 95%CI: 1.31-12.64) were independently associated with syphilis-infection. In addition, pregnant women with TRUST titer ≥1:8 (AOR = 2.81; 95%CI: 1.87-4.21), having a history of adverse pregnancy outcomes (AOR = 1.70; 95%CI: 1.14-2.53), reporting multi-partners (AOR = 0.43; 95%CI: 0.29-0.64) and reporting the current partner as the source of syphilis (AOR = 5.05; 95%CI: 2.82-9.03) were independently associated with partners' syphilis-infection.ConclusionContact tracing is feasible and effective in identifying syphilis-infected partners among syphilis-seropositive pregnant women. Contact tracing is associated with many factors such as women's marital status, services at their first antenatal clinics visit and willingness of partner notification. Partners' ethnicity, age at first sex, multi-partners and history of drug abuse as well as women's levels of TRUST titer were associated with partners' syphilis-infection.
