Active Syphilis

Background Syphilis in Peru is heavily concentrated in men who have sex with men (MSM) and transgender women (TGW). The aim of the present study was to understand the risk factors for active syphilis infection among MSM and TGW in Peru. Methods: Independent correlates suggestive of active syphilis infection were examined to better understand risk factors for syphilis in MSM and TGW, with separate analyses conducted based on location and among TGW. In 2011, 5101 MSM and TGW completed both self-report surveys and HIV and syphilis testing in five Peruvian cities. Results: Overall, 261 (5.1%) MSM and TGW met the criteria for active syphilis, with higher prevalence in Lima than elsewhere (7.0% vs 3.0%) and in TGW than in MSM (10.7% vs 4.2%). Significant independent correlates of active syphilis infection differed greatly by location. In Lima, they included being HIV-infected (aware or unaware of status), being a TGW, being a high school graduate, engaging in receptive anal intercourse, no recent sex with a female partner and having had any symptomatic sexually transmissible infection, including syphilis, in the previous 6 months. Outside Lima, the independent correlates included being HIV-infected and unaware of status, engaging in recent sex work, no recent sex with a female partner and age 35–44 years. Among TGW, independent correlates of active syphilis included being HIV-infected (aware or unaware of status), a recent syphilis diagnosis in the previous 6 months and recent drug use. Conclusion: The findings of the present study support the need not only for combined HIV and syphilis screening, but also for increased screening and treatment of syphilis in MSM and TGW populations. Stratified analyses suggest different syphilis epidemics throughout the country and in TGW, yet being HIV-infected and aware were consistently associated with active syphilis, suggesting higher syphilis risk in HIV-infected MSM and TGW.

Objective. To investigate factors associated with HIV infection and the frequency and willingness of male circumcision among men who have sex with men (MSM) in Chengdu city, China.Methods. A cross-sectional survey provided information on participants' demographics, risk behaviors, circumcision, and uptake of HIV prevention services.Results. Of 570 participants, 13.3% were infected with HIV and 15.9% with syphilis. An estimated 43.0% of respondents reported having unprotected receptive anal intercourse, and 58.9% reported having ≥2 male sexual partners in the past 6 months. Multivariable logistic regression revealed that syphilis, more male sex partners, predominantly receptive anal intercourse, and exclusively receptive male sex were associated with HIV infection. Higher level of education and peer education service were inversely associated with HIV infection. Nearly a fifth (18.0%) of participants were circumcised. More than half of uncircumcised participants expressed willingness to be circumcised.Conclusion. This study reveals a high prevalence of HIV and syphilis among MSM in Chengdu province of China. The frequency of unprotected receptive anal intercourse and multiple male sexual partnerships highlight the urgency for an effective comprehensive HIV prevention strategy. Although the willingness to accept male circumcision (MC) is high, further research is needed to assess the protective effective of MC among MSM.

Despite widespread prevalence of lubricant use and rectal douching for receptive anal intercourse (RAI) among men who have sex with men (MSM), research evaluating the association of these behaviors with sexually transmitted infections (STIs) is limited. This is an observational analysis of a longitudinal cohort of predominantly Black/Latino MSM in Los Angeles. Every six months from August 2014 to January 2018, participants received STI screening and surveys evaluating lubricant use, douching, substance use, and sexual risk behaviors. General estimating equations evaluated the association between consistent lubricant use and douching for RAI with positive rectal Neisseria gonorrhoeae, Chlamydia trachomatis, and/or syphilis (positive STI). Among 313 participants across 552 study visits, 16.5% (91/552) had positive STI. Consistent lubricant use was reported in 52.7% (243/552) and rectal douching in 57.6% (318/552) of study visits. Consistent lubricant use was associated with STI diagnosis (adjusted OR [AOR] 1.81; 95% CI 1.11–2.96; p = 0.018). Each episode of rectal douching before RAI was associated with 2% increased odds of positive STI (AOR 1.02; 95% CI 1.00–1.04; p = 0.041). Among this cohort of HIV-positive and high-risk HIV-negative MSM, lubricant use and douching was common and independently associated with an STI, suggesting the utility of prevention messaging around barrier methods/condoms for sexual encounters involving douching/lubricant use.

Objective. To classify the infection risk of human papillomavirus (HPV) among human immunodeficiency virus- (HIV-) negative men who have sex with men (MSM) using group-based trajectory modeling (GBTM). Methods. This study collected data on demographic and sexual behavior characteristics by questionnaires at semiannual visits from March 1st, 2016 to December 31th, 2017. Researchers collected anal exfoliated cells to finish HPV testing and blood samples to finish HIV testing at baseline and follow-up visits. Accumulative infection numbers of different types of HPV as the primary outcome and the follow-up visits as the independent predicator to build a GBTM model. Results. There were 500 potentially eligible HIV-negative participants at baseline, 361 (72.2%) of whom were included in this study after screening. Three trajectory groups were identified as the best-fitted GBTM model. Trajectory 1, defined as decreased group (DG) accounted for 44.6% (161/361) of the sample, showed a declining pattern with visits. Trajectory 2, defined as flat group (FG) accounted for 49.6% (179/361) of the sample, showed a flat pattern with visits. Trajectory 3, regarded as the increased group (IG) accounted for 5.8% (21/361) of the sample, showed an uptrend. Compared to the DG, risk factors for the FG included receptive anal intercourse (AOR, 2.24; 95% CI, 1.36-3.71), occasional condom use in anal sex during the past six months (AOR, 1.90; 95% CI, 1.16-3.14), experience of transactional sex with males in the past year (AOR, 3.60; 95% CI, 1.12-11.54), and substance use (AOR, 1.81; 95% CI, 1.08-3.04). Risk factors for the IG included receptive anal intercourse (AOR, 2.81; 95% CI, 1.04-7.70), occasional condom use in anal sex during the past six months (AOR, 3.93; 95% CI, 1.40-11.01), and history of other STIs (AOR, 5.72; 95% CI, 1.40-23.46). Conclusion. The MSM data in this study showed three distinct developmental trajectories (DG, FG, and IG) of HPV infection among HIV-negative MSM, with receptive anal intercourse and occasional condom use in anal sex during the past six months being the risk factors associated with FG and IG.

Background Hepatitis A is a fecal-oral infection caused by hepatitis A virus (HAV). Men who have sex with men (MSM) and transgender women (TW) have been reported as target groups for HAV infection. This study aimed to determine the seroprevalence, risk factors, and circulating strains associated with HAV infection among MSM and TW in Central Brazil. Methods A cross-sectional study was conducted from November 2011 to September 2013. Serum samples were collected from 425 individuals for anti-HAV antibody testing and HAV molecular characterization. Of them, 149 (35.1%) participants were self-identified as transgender women. Statistical analysis was performed to evaluate the risk factors of HAV seropositivity. Results The seroprevalence of HAV exposure was 69.7% (95% Confidence Interval: 65.3–74.0%). Serological evidence of HAV was significantly higher in participants who self-identified as transgender women (83.2%) than MSM (62.3%). Increasing age, non-white race, and lower monthly household income were independently associated with HAV exposure among MSM. Only lower monthly household income was independently associated with HAV exposure among TW. One anti-HAV IgM positive sample, from a transgender woman (0.2%), was detected and classified as subgenotype IA. Conclusions High HAV prevalence was observed, markedly among TW. Considering the risky sexual behaviors this population is exposed to, HAV vaccination and prevention programs targeting this population should be considered to prevent outbreaks and the burden of the disease.

Abstract Background Syphilis control among men who have sex with men (MSM) would be improved if we could increase the proportion of cases who present for treatment at the primary stage rather than at a later stage, as this would reduce their duration of infectivity. We hypothesized that MSM who practiced receptive anal intercourse were more likely to present with secondary syphilis, compared to MSM who did not practice receptive anal intercourse. Methods In this retrospective analysis of MSM diagnosed with primary or secondary syphilis at Melbourne Sexual Health Centre between 2008 and 2017, we analyzed associations between the stage of syphilis (primary vs secondary) and behavioral data collected by computer-assisted self-interviews. Results There were 559 MSM diagnosed with primary (n = 338) or secondary (n = 221) syphilis. Of these, 134 (24%) men reported not practicing receptive anal sex. In multivariable logistic regression analysis, MSM were more likely to present with secondary rather than primary syphilis if they reported practicing receptive anal intercourse (adjusted odds ratio 3.90; P < .001) after adjusting for age, human immunodeficiency virus status, and condom use. MSM with primary syphilis who did not practice receptive anal intercourse almost always (92%) had their primary syphilis lesion on their penis. Conclusions The finding that MSM who practiced receptive anal intercourse more commonly presented with secondary syphilis—and hence, had undetected syphilis during the primary stage—implies that anorectal syphilis chancres are less noticeable than penile chancres. These men may need additional strategies to improve early detection of anorectal chancres, to reduce their duration of infectivity and, hence, reduce onward transmission. Men who practiced receptive anal intercourse (AI) were more likely to present with secondary syphilis, compared to men who exclusively practiced insertive AI. Hence, men who practice receptive AI may need additional strategies to detect anal chancres, to reduce transmission.
