Objectives To examine whether rectal gonorrhoea (RG; Neisseria gonorrhoeae) can be used as a lead indicator of trends in HIV diagnosis in men who have sex with men (MSM). Methods: Data from a metropolitan sexual health centre in Victoria, Australia, on RG and HIV tests in HIV-negative MSM from January 2006 to December 2011 were examined. Results: Allowing RG a 12-month lead over HIV showed no concordance in proportion positive (r = 0.27; P-value = 0.28). Conclusions: The data do not support use of RG trends as a lead indicator of trends in HIV among MSM.

ObjectiveIn 2017, there was an outbreak of invasive meningococcal disease (IMD) serogroup C among men who have sex with men (MSM) in Victoria, Australia. A government-funded free meningococcal (MenACWY) vaccination programme targeting all MSM living in Victoria was launched between December 2017 and December 2018. The aim of this study was to examine the vaccine uptake among MSM attending a sexual health clinic in Melbourne.MethodsThis was a retrospective clinical audit of MSM attending the Melbourne Sexual Health Centre (MSHC) during the vaccination programme. We calculated the proportion of MSM who received the meningococcal vaccine on their first visit and at any time during the programme. We performed univariable and multivariable logistic regression to identify the factors associated with the vaccine uptake on the first visit.ResultsOf the 10 370 MSM who attended MSHC, 55.5% received the vaccine on their first visit and 67.4% at any time during the programme. MSM had higher odds of receiving the vaccine on the first visit if they were aged 16–25 years (adjusted OR (aOR) 1.21; 95% CI 1.08 to 1.35) or 26–35 years (aOR 1.17; 95% CI 1.07 to 1.29) in comparison with MSM older than 35 years; were HIV-negative and not on pre-exposure prophylaxis (aOR 1.80; 95% CI 1.56 to 2.09); had more than four male partners in the last 12 months (aOR 1.16; 95% CI 1.06 to 1.27); had male partners only (aOR 2.24; 95% CI 1.96 to 2.55); or were born overseas (aOR 1.11; 95% CI 1.03 to 1.21).ConclusionsTwo-thirds of the MSM attending a sexual health clinic received at least one dose of meningococcal vaccine. The vaccination programme coincided temporally with a dramatic reduction in the incidence of IMD. Vaccination should be further promoted among MSM and men who have sex with both men and women.

ObjectiveTo better understand rectal STI screening practices for Black gay, bisexual and other men who have sex with men (BGBMSM).FindingsAlthough 15% of BGBMSM lab tested positive for a rectal STI, the majority of these (94%) were asymptomatic. Though all participants reported their status as HIV negative/unknown, 31 of 331 (9.4%) tested positive on HIV rapid tests. Neither condomless anal intercourse nor the number of male sex partners was associated with rectal STI or HIV diagnosis, although rectal STI diagnosis was positively related to testing HIV positive.ConclusionsFindings suggest that substantial numbers of BGBMSM have asymptomatic STIs but are not tested—an outcome that is likely a strong driver of onward HIV acquisition. Therefore, we must address the asymptomatic STI epidemic among GBMSM in order to reduce HIV transmission, as well as temper STI transmission, among this key population.

Men who have sex with men (MSM) attending sexual health (SH) clinics are at high risk for HIV acquisition and are disproportionately affected by sexually transmitted infections (STIs). We collected standardised behavioural data from MSM attending clinics to characterise sexual behaviours and identify predictors for HIV and STIs. In 2012–2013, HIV-negative MSM attending five SH clinics in England reported sexual behaviours in the previous three months via a self-administered questionnaire. Behaviours were linked to the individual’s clinical records using national surveillance. The prevalence and incidence of bacterial STIs (gonorrhoea, Chlamydia, lymphogranuloma venereum and syphilis) and incidence of HIV were calculated. Adjusted odds ratios and hazard ratios with 95% confidence interval (CI) were reported for significant predictors. Of 1278 HIV-negative MSM, 54% were of white ethnicity and UK-born and 43% were 25–34 years old. Almost all men reported at least one partner in the last three months. Half reported condomless anal sex and 36% condomless receptive anal intercourse (CRAI). Incidence of bacterial STIs was 46/100 (95%CI 39–54) person years (py) and of HIV was 3.1/100 (95%CI 1.7–5.6) py. A STI at baseline and CRAI with increasing numbers of partners were associated with both incident infections. In this cohort of MSM high-risk behaviours and STIs were prevalent. Engagement in CRAI increased the likelihood of subsequent infection, while men diagnosed with a bacterial STI were at increased risk of a future STI. Clinical and behavioural risk assessments to determine an individual’s risk of infection could allow a more nuanced prevention approach that has greater success in reducing transmission.

Asymptomatic Men

BackgroundIn a previous study of men attending Melbourne Sexual Health Centre who had Neisseria gonorrhoeae detected by urine Aptima Combo 2 (AC2) testing, 11% were asymptomatic. This study aimed to determine whether N. gonorrhoeae can be cultured from asymptomatic men screening positive for N. gonorrhoeae by nucleic acid amplification testing (NAAT) of urine.MethodsBetween 1 July 2017 and 31 March 2019, all men attending Melbourne Sexual Health Centre were tested for N. gonorrhoeae by AC2 testing of urine whether urethral symptoms were reported or not. NAAT-positive men were recalled and a urethral swab performed for gonococcal culture using modified Thayer-Martin media with determination of minimum inhibitory concentrations (MICs) by agar dilution.ResultsThere were 1001 cases (860 individuals) positive for N. gonorrhoeae by urine AC2: 892 (89%) reported urethral symptoms; 109 (11%) did not. Twenty-five asymptomatic cases were excluded because of antibiotic use at or following screening. Of the remaining 84 asymptomatic men, 41 (49%) had a urethral swab performed a median of 5 days after screening. Twenty-one men had urethral discharge at the return visit, 11 of whom reported the discharge at the return visit. Of the 41 men who were swabbed, 31 (76%; 95% CI 60% to 88%) were culture positive for N. gonorrhoeae. Among the 21 men who subsequently developed discharge, 19 (90%; 95% CI 70% to 99%) were culture positive. Among the 20 men who remained asymptomatic, 12 (60%; 95% CI 36% to 81%) were culture positive. MIC profiles were obtained from all isolates.ConclusionsGonorrhoea was isolated in most but not all asymptomatic men screening positive for N. gonorrhoeae by urine NAAT. Clinicians should consider performing urethral culture in such men to ensure optimal surveillance for antimicrobial resistance. Isolation of N. gonorrhoeae by culture in men without discharge indicates these are true infections with viable organisms.

Background Sexually transmissible infections (STIs) have been increasing in men who have sex with men (MSM) in recent years; however, few studies have investigated the prevalence or antimicrobial resistance in rectal Mycoplasma genitalium in this group. This study aimed to determine the prevalence and predictors of rectal M. genitalium in MSM attending an urban sexual health service in Sydney, Australia, namely the Sydney Sexual Health Centre (SSHC), as well as estimate the rate of macrolide resistance. Methods: A prospective cross-sectional analysis was conducted of rectally asymptomatic MSM having a rectal swab collected as part of their routine care. Participants self-collected a rectal swab to be tested for M. genitalium and completed a 14-item questionnaire that provided information on behavioural risk factors. The prevalence of rectal M. genitalium was determined and multivariate analysis was performed to assess the associations for this infection. Positive specimens then underwent testing for macrolide-resistant mutations (MRMs) using the ResistancePlus MG assay (SpeeDx, Eveleigh, NSW, Australia). Results: In all, 742 patients were consecutively enrolled in the study. The median age was 31 years (interquartile range 27–39 years), with 43.0% born in Australia. Overall, 19.0% of men were bisexual, 22.9% were taking pre-exposure prophylaxis (PrEP) and 4.3% were HIV positive. The prevalence of rectal M. genitalium was 7.0% (95% confidence interval (CI) 5.3–9.1) overall and 11.8% in those taking PrEP. On multivariate analysis, PrEP use was significantly associated with having rectal M. genitalium (odds ratio 2.01; 95% CI 1.09–3.73; P = 0.01). MRMs were detected in 75.0% (36/48; 95% CI 60.4–86.4%) of infections. Conclusion: Rates of rectal M. genitalium infection were high among asymptomatic MSM attending SSHC and MRMs were detected in 75% of infections. PrEP use was found to be significantly associated with rectal M. genitalium infection. These data contribute to the evidence base for screening guidelines in MSM.

ObjectiveLondon has one of the highest identified prevalence of chemsex (sexualised recreational drug use) among men who have sex with men (MSM) in Europe. We examine MSM’s patterns of chemsex and its association with HIV/STI risk behaviours, STI diagnoses and sexual healthcare-seeking behaviours, including if HIV testing behaviour met UK national guidelines (three monthly if engaging in chemsex).MethodsCross-sectional survey data from 2013 (n=905) and 2016 (n=739) were collected using anonymous, self-administered questionnaires from MSM recruited in commercial gay venues in London, UK. Descriptive and multivariable analyses, stratified by self-reported HIV status, were conducted. Adjusted prevalence ratios (aPR) with 95% CIs were calculated.ResultsComparing the 2013 and 2016 surveys, chemsex prevalence in the past year remained stable, in both HIV-negative/unknown-status MSM (20.9% in 2013 vs 18.7% in 2016, p=0.301) and HIV-positive MSM (41.6% in 2013 vs 41.7% in 2016, p=0.992). Combined 2013–2016 data showed that compared with other MSM, those reporting chemsex were more likely to report HIV/STI risk behaviours, including condomless anal intercourse with serodifferent HIV-status partners (HIV-negative/unknown-status men: aPR 2.36, 95% CI 1.68 to 3.30; HIV-positive men: aPR 4.19, 95% CI 1.85 to 9.50), and STI diagnoses in the past year (HIV-negative/unknown-status men: aPR 2.10, 95% CI 1.64 to 2.69; HIV-positive men: aPR 2.56, 95% CI 1.57 to 4.20). 68.6% of HIV-negative/unknown-status men reporting chemsex attended sexual health clinics and 47.6% had tested for HIV more than once in the past year.ConclusionsChemsex in London MSM remained stable but high, particularly among HIV-positive men. Irrespective of HIV status, chemsex was associated with engagement in HIV/STI risk behaviours. Frequency of HIV testing in the past year among HIV-negative/unknown-status men was below national recommendations. Promoting combination prevention strategies, including three monthly HIV/STI testing, access to pre-exposure prophylaxis/antiretroviral treatment and behavioural interventions among MSM reporting chemsex, remains vital to address sexual health inequalities in MSM.

Abstract Background The “Undetectable = Untransmittable” (“U=U”) campaign is gaining traction, but prior studies from 2012–2017 have shown that the proportion of gay and bisexual men who have sex with men (GBMSM) who are aware of or have perceived accuracy of U=U is low. We report findings from a survey administered to GBMSM in 2018 to understand whether the landscape is changing with respect to U=U message dissemination. Methods GBMSM were recruited on gay dating apps to complete a 96 question survey. Survey data were collected in April-August of 2018. Collected data elements included demographic information, HIV status, ART and PrEP use, and beliefs and opinions regarding HIV transmission. Results 969 GBMSM completed the survey; of whom, 678 had analyzable data (241 had never had anal sex with a man and 54 were missing ≥1 of the variables used in the analysis). Average age was 43 years, 65% were white, 15% black, 15% white, and 15% were HIV-infected (of whom 92% were on anti-retrovirals). Of the 85% who were HIV-uninfected, 39% were on PrEP. In response to the statement that a person with an undetectable viral load cannot transmit HIV to an HIV-uninfected person, 24% strongly agreed. Among HIV-negative GBMSM, 33% of those on PrEP agreed and 12% of those not on PrEP agreed. Among those living with HIV, 42% agreed. A multivariable logistic regression was run to explain correlates of strong agreement with U=U, using the following variables: age, education, being Black, being Hispanic, relationship status, number of lifetime male sexual partners, condom use with most recent anal sex, HIV status, PrEP use, and attitudes about living with HIV. Variables associated with strong agreement with U=U were living with HIV (AOR = 1.63, P < 0.001), taking PrEP (AOR = 2.85, P < 0.001), most recent encounter’s condom use (AOR = 2.22, P = 0.003), and having positive attitudes about living with HIV (AOR= 1.93, P < 0.001). Table 1 shows percentages for each of these variables (bivariate relationships) strongly agreeing with U=U. Conclusion Now that U=U has been scientifically proven, the challenge is public awareness. U=U awareness seems to be improving among GBMSM, with HIV-negative GBMSM making the greatest strides. Education around U=U and PrEP efficacy may help reduce guilt around HIV transmission and alleviate HIV stigma. Disclosures All authors: No reported disclosures.

The Impact

Background: A recent audit indicated that a substantial proportion of men who have sex with men (MSM) were not screened for rectal gonorrhoea and chlamydia at the Melbourne Sexual Health Clinic, Melbourne, Australia. In response, screening guidelines for MSM were introduced at the clinic using a computer reminder. The aim of this study was to evaluate the impact of the guidelines and alert on screening MSM for gonorrhoea and chlamydia. Methods: The medical records of MSM were reviewed for gonorrhoea and chlamydia screening by site (pharyngeal, urethral and rectal), four months before the implementation of the guidelines and alert (July to October 2002), and one year thereafter (beginning November 2002). Results: After the introduction of the guidelines there was a significant increase in rectal chlamydia testing (55% to 67%, P < 0.001), and significant reduction in pharyngeal chlamydia and gonorrhoea testing (65% to 28%, P < 0.001, and 83% to 76%, P = 0.015 respectively). The proportion of tests that were positive by any site did not change (7% to 7%). Conclusions: The introduction of a computer reminder for new guidelines was temporally associated with screening that conformed more closely to clinical guidelines.

‘Fuckbuddies’ are a type of regular sexual partner with whom men have ongoing sexual contact, generally in the absence of romantic attachment. We surveyed 989 men who have sex with men (MSM) at the Melbourne Sexual Health Centre, Australia, with the aim of determining the frequency of ‘fuckbuddy’ partnerships among sexual health clinic attendees and assessing their sexual risk. The majority (60%) of 1139 regular partnerships were described as ‘fuckbuddies’. Most MSM (63%) with a ‘fuckbuddy’ had multiple ‘fuckbuddies’. MSM with ‘fuckbuddies’ were more likely to also have casual sexual partners (odds ratio [OR] 5.7; 95% confidence interval 3.6–8.9) and had more casual sexual partners (median of 4 versus 1, p < 0.001) and more rectal chlamydia (12.4% versus 5.7%; adjusted OR 2.3; p < 0.05) than MSM without ‘fuckbuddies’, and this risk persisted after adjusting for total numbers of sexual partners. Our findings suggest that patients with ‘fuckbuddies’ are at particular risk of sexually transmitted infections. We argue that clinicians should specifically ask about ‘fuckbuddy’ partnerships as part of their risk assessment during patient interviews, as these patients may benefit from HIV prevention strategies such as pre-exposure prophylaxis (PrEP).

ObjectivesThe incidence of Neisseria gonorrhoeae and its antimicrobial resistance is increasing in many countries. Antibacterial mouthwash may reduce gonorrhoea transmission without using antibiotics. We modelled the effect that antiseptic mouthwash may have on the incidence of gonorrhoea.DesignWe developed a mathematical model of the transmission of gonorrhoea between each anatomical site (oropharynx, urethra and anorectum) in men who have sex with men (MSM). We constructed four scenarios: (1) mouthwash had no effect; (2) mouthwash increased the susceptibility of the oropharynx; (3) mouthwash reduced the transmissibility from the oropharynx; (4) the combined effect of mouthwash from scenarios 2 and 3.SettingWe used data at three anatomical sites from 4873 MSM attending Melbourne Sexual Health Centre in 2018 and 2019 to calibrate our models and data from the USA, Netherlands and Thailand for sensitivity analyses.ParticipantsPublished available data on MSM with multisite infections of gonorrhoea.Primary and secondary outcome measuresIncidence of gonorrhoea.ResultsThe overall incidence of gonorrhoea was 44 (95% CI 37 to 50)/100 person-years (PY) in scenario 1. Under scenario 2 (20%–80% mouthwash coverage), the total incidence increased (47–60/100 PY) and at all three anatomical sites by between 7.4% (5.9%–60.8%) and 136.6% (108.1%–177.5%). Under scenario 3, with the same coverage, the total incidence decreased (20–39/100 PY) and at all anatomical sites by between 11.6% (10.2%–13.5%) and 99.8% (99.2%–100%). Under scenario 4, changes in the incidence depended on the efficacy of mouthwash on the susceptibility or transmissibility. The effect on the total incidence varied (22–55/100 PY), and at all anatomical sites, there were increases of nearly 130% and large declines of almost 100%.ConclusionsThe effect of mouthwash on gonorrhoea incidence is largely predictable depending on whether it increases susceptibility to or reduces the transmissibility of gonorrhoea.
