Extragenital Chlamydia and Gonorrhea Among Community Venue-Attending Men Who Have Sex with Men - Five Cities, United States, 2017.

Sexually transmitted diseases (STDs) disproportionately affect gay, bisexual, and other men who have sex with men (MSM) in the United States (1). Because chlamydia and gonorrhea at extragenital (rectal and pharyngeal) anatomic sites are often asymptomatic, these anatomic sites serve as a reservoir of infection, which might contribute to gonococcal antimicrobial resistance (2) and increased risk for human immunodeficiency virus (HIV) transmission and acquisition (3). To ascertain prevalence of extragenital STDs, MSM attending community venues were recruited in five U.S. cities to provide self-collected swabs for chlamydia and gonorrhea screening as part of National HIV Behavioral Surveillance (NHBS). Overall, 2,075 MSM provided specimens with valid results, and 13.3% of participants were infected with at least one of the two pathogens in at least one of these two extragenital anatomic sites. Approximately one third of participating MSM had not been screened for STDs in the previous 12 months. MSM attending community venues had a high prevalence of asymptomatic extragenital STDs. The findings underscore the importance of sexually active MSM following current recommendations for STD screening at all exposed anatomic sites at least annually (4).

Prevalence of hepatitis C infection, screening and associated factors among men who have sex with men attending gay venues: a cross-sectional survey (PREVAGAY), France, 2015

BackgroundOver the last 20 years, Hepatitis C virus (HCV) infection prevalence has dramatically increased among HIV-infected men who have sex with men (MSM) in many countries worldwide. It is suspected that this increase is primarily driven by sexual behaviours linked to blood exposure. Monitoring these behaviours is crucial to understand the drivers of the epidemic. This study assessed the prevalence of chronic HCV infection among MSM attending gay venues and associated chronic HCV risk factors. HCV screening and associated factors were described.MethodsThe cross-sectional survey PREVAGAY, based on time-location sampling, was conducted in 2015 among MSM attending gay venues in 5 French metropolitan cities. A self-administered questionnaire was completed and capillary whole blood on dried blood spots (DBS) collected. Possible factors associated with chronic HCV prevalence and with HCV screening in the previous year were investigated using Poisson regression.ResultsChronic HCV infection prevalence from DBS analysis was 0.7% [IC95%: 0.3–1.5] in the study’s 2645 participants and was 3.0% [1.5–5.8] in HIV-positive MSM. It was significantly higher in those who reported the following: (lifetime) slamming (with or without the sharing of injection equipment); (during the previous year) fisting and chemsex, unprotected anal intercourse with casual partners, using gay websites and/or of mobile-based GPS applications, and having more than 10 sexual partners.Only 41.3% [38.2–44.5] of the participants reported HCV screening during the previous year. Screening was significantly more frequent in MSM under 30 years of age, those who were HIV-positive, those vaccinated against hepatitis B and meningococcus C, and those who reported the following (during the previous year): more than 10 sexual partners, at least one sexually transmitted infection and fisting.ConclusionChronic HCV infection prevalence in MSM attending gay venues was significantly higher in HIV-positive MSM and in those with risky sexual behaviours. Reflecting current screening recommendations for specific populations, previous HCV screening was more frequent in HIV-positive individuals and those with risky sexual behaviours. Nevertheless, HCV screening coverage needs to be improved in these populations. Comprehensive medical management, which combines screening and linkage to care with prevention strategies, is essential to control HCV among MSM.

Prevalence and factors associated with gonorrhea infection with respect to anatomic distributions among men who have sex with men.

IntroductionGonorrhea (GC) infection caused by Neisseria gonorrhoeae has been steadily increasing in Thailand over the last decade. Men who have sex with men (MSM) are at high risk for gonorrhea infection.Materials and methodsIn this study, we determined the prevalence of and risk factors associated with gonococcal infections by three anatomical sites among MSM. We have conducted a cross-sectional analysis of a sexually transmitted disease (STD), gonorrhea among MSM attending two STD clinics in Khon Kaen, Thailand. We included 358 MSM over 18 years of age. Data were collected using self-administered questionnaire. In each participant, an oropharyngeal, anorectal, and endourethral swab were tested with culture and nucleic acid amplification test (NAAT). However, 267 urine samples were tested by both methods. Factors associated with gonorrhea infections were assessed using univariate and multivariate logistic regression.ResultsOne hundred and ninety-five out of 358 (54.47%) MSM tested were found to be positive for gonorrhea using a porA gene targeted NAAT by Real-time PCR with TaqMan probes, but there was no positive result by culture. The gonorrheal prevalence for male genital site, anal, and oropharyngeal, were 34.73% (95%CI 33.07, 45.08), 29.01% (95%CI 24.61, 34.33), and 27.93% (95%CI 23.35, 32.89), respectively, while 5.9% (21/355) were positive for gonococcal infection in all anatomic sites (oropharynx + anus + urethra) of one participant. Previous history of diagnosed STDs was a significant factor associated urethral gonorrhea (odds ratio = 3.52, 95%CI 1.87–6.66, P Value< 0.001). In addition, having more than one partner was increased urethral gonorrhea (adjusted odds ratio = 2.26, 95%CI 1.10–4.68, P Value = 0.026). 100% of condom use was found decreasing urethral infection (adjusted odds ratio = 0.39, 95%CI 0.15–0.99, P Value = 0.046).ConclusionsThe most common anatomic site of gonorrhea infection was male genital site, and the independent risk factors were having history of diagnosed STDs and having more than one partner in the past 3 months, but 100% condom use was a protective factor of this infection.

Primary Incidence of Hepatitis C Virus Infection Among HIV-Infected Men Who Have Sex With Men in San Diego, 2000-2015.

BackgroundLittle is known about the hepatitis C virus (HCV) epidemic among HIV-infected men who have sex with men (HIV+ MSM) in the United States. In this study, we aimed to determine the incidence of primary HCV infection among HIV+ MSM in San Diego, California.MethodsWe performed a retrospective cohort analysis of HCV infection among HIV+ MSM attending 2 of the largest HIV clinics in San Diego. Incident HCV infection was assessed among HIV+ MSM with a negative anti-HCV test and subsequent HCV test between 2000 and 2017, with data censored to 2015. HCV reinfection was assessed among HIV+ MSM successfully treated for HCV between 2008 and 2015. Infection/reinfection rates were calculated using person-time methods.ResultsAmong 3068 initially HCV-seronegative HIV+ MSM, 178 new infections occurred over 15 796 person-years, giving an incidence of 1.13 per 100 person-years (/100py; 95% confidence interval [CI], 0.97–1.31). Incidence was stable from 2000 to 2014 (0.83/100py; 95% CI, 0.41–1.48), with an increase to 3.01/100py (95% CI, 1.97–4.42) in 2015 (P = .02). Among 43 successfully treated patients, 3 were reinfected.ConclusionsHCV incidence is high among HIV+ MSM in San Diego, with evidence suggesting a recent increase in 2015. Strong HCV testing guidelines and active prevention efforts among HIV+ MSM are urgently needed that include rapid diagnosis, treatment, and risk reduction.

HIV and syphilis and sexual risk behaviours among men who have sex with men attending university in China: a systematic review and meta-analysis.

Five databases were searched for student MSM information in English and Chinese language publications. Meta-analyses were performed to calculate the pooled prevalence of HIV and syphilis, pooled mean age at first anal intercourse (AFAI) and the rate of other HIV-related behaviours among MSM attending university in China. Univariate meta-regression and subgroup analysis were conducted to explore potential sources of heterogeneity. Publication bias was measured using Egger's test. Thirty-three articles representing 31 studies were included in the analysis. The pooled HIV prevalence was 4.1% (95% CI 3.1-5.0%). The estimated AFAI was 18.7 years, but 37.5% of students had their first anal intercourse before 18 years of age. Most (88.2%) had their first sexual intercourse with a male partner. Of the MSM attending university, 4.2% of MSM engaged in commercial sex (either selling or buying sex), 10.3% had ever engaged in group sex, 13.1% had had sex with a female partner in the past month and 10.1% had ever used drugs. Most (77.7%) sought sex partners via geosocial networking gay apps or the Internet, and 42.9% had ever tested for HIV. There was a tendency for an increase in lifetime HIV testing rate from 32% in 2005-07 to 53% in 2014-16. This review found high HIV prevalence, early AFAI and a high prevalence of sexual risk behaviours among MSM attending university in China. Interventions aimed at increasing HIV testing and reducing sexual risk behaviours are urgently needed among this young population.

Predicting STI Diagnoses Amongst MSM and Young People Attending Sexual Health Clinics in England: Triage Algorithm Development and Validation Using Routine Clinical Data

BackgroundSexual health (SH) services increasingly need to prioritise those at greatest risk of sexually transmitted infections (STIs). We used SH surveillance data to develop algorithms to triage individuals attending SH services within two high-risk populations: men who have sex with men (MSM) and young people (YP). MethodsSeparate multivariable logistic regression models for MSM and YP were developed using surveillance data on demographics, recent sexual history, prior STI diagnoses and drug/alcohol use from five clinics in 2015–2016 to identify factors associated with new STI diagnoses. The models were prospectively applied in one SH clinic in May 2017 as an external validation. Findings9530 YP and 1448 MSM SH episodes informed model development. For YP, factors associated with new STI diagnosis (overall prevalence: 10.6%) were being of black or mixed white/black ethnicity; history of chlamydia diagnosis (previous year); and multiple partners/new partner (previous 3-months). The YPs model had reasonable performance (c-statistic: 0.703), but poor discrimination when externally validated (c-statistic: 0.539). For MSM, being of South Asian ethnicity; being born in Europe (excluding the UK); and condomless anal sex or drug use (both in previous 3-months) were associated with STI diagnosis (overall prevalence: 22.0%). The MSM model had a c-statistic of 0.676, reducing to 0.579 on validation. InterpretationSH surveillance data, including limited behavioural data, enabled triage algorithms to be developed, but its implementation may be problematic due to poor external performance. This approach may be more suitable to self-triage, including online, ensuring patients are directed towards appropriate services. FundingNIHR HTA programme (12/191/05).

Sexual behaviours and sexually transmitted infection outcomes in a cohort of HIV-negative men who have sex with men attending sexual health clinics in England.

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.

HIV Testing With and Without a Clinical Consultation Among Men Who Have Sex With Men: A Randomized Controlled Trial

Increasing the frequency of HIV testing among men who have sex with men (MSM) maximizes the preventive effect of antiretroviral therapy, by reducing time to diagnosis and treatment. Melbourne Sexual Health Centre, Australia. This randomized controlled trial evaluated whether access to testing, without seeing a clinician would increase testing frequency. MSM attending for HIV testing between July 2014 and April 2015 were randomized in 1:1 ratio to the intervention arm (access to HIV and syphilis testing at 300 pathology centers, without requiring consultations) or the control arm (consultation at every test), without blinding. The primary outcome was the incidence of HIV testing over 12 months. Of 443 men referred, 422 were randomized, 3 HIV positives at baseline were excluded, and 419 were analyzed. Of 208 control, 202 (97.1%) and 200 (94.8%) of 211 intervention group members were followed to 12 months. The intervention group had 453 tests in 205.6 person-years, incidence rate was 2.2 (95% confidence interval [CI]: 2.0 to 2.4) tests per year. The control group had 432 tests during 204.0 person-years, incidence rate was 2.1 (95% CI: 1.9 to 2.3) tests per year, and incidence rate ratio was 1.04 (95% CI: 0.89 to 1.2; P = 0.63). The annual rate of consultations was as follows: intervention, 1.61 (95% CI: 1.44 to 1.79); controls, 2.12 (95% CI: 1.92 to 2.33); rate ratio, 0.76 (95% CI: 0.65 to 0.88; P = 0.0001). There was no difference in quality of life scores (P = 0.61). MSM permitted HIV and syphilis testing outside of clinical consultations did not test more frequently than controls but had 24% fewer consultations, reducing service demand. ACTRN12614000760673.

Time location sampling in men who have sex with men in the HIV context: the importance of taking into account sampling weights and frequency of venue attendance.

Sex between men is the most frequent mode of HIV transmission in industrialised countries. Monitoring risk behaviours among men who have sex with men (MSM) is crucial, especially to understand the drivers of the epidemic. A cross-sectional survey (PREVAGAY), based on time-location sampling, was conducted in 2015 among MSM attending gay venues in 5 metropolitan cities in France. We applied the generalised weight share method (GWSM) to estimate HIV seroprevalence for the first time in this population, taking into account the frequency of venue attendance (FVA). Our objectives were to describe the implementation of the sampling design and to demonstrate the importance of taking into account sampling weights, including FVA by comparing results obtained by GWSM and by other methods which use sample weights not including FVA or no weight. We found a global prevalence of 14.3% (95% CI (12.0-16.9)) using GWSM and an unweighted prevalence of 16.4% (95% CI (14.9-17.8)). Variance in HIV prevalence estimates in each city was lower when we did not take into account either the sampling weights or the FVA. We also highlighted an association of FVA and serological status in the most of investigated cities.

P245 Monitoring the uptake and early impact of targeted hpv vaccination among men who have sex with men (msm) attending gum and hiv clinics in england

IntroductionMSM are at high risk for HPV infection and associated disease (genital warts and anal, oropharyngeal, and penile cancers). Additionally, MSM will receive little or no herd protection from the existing national vaccination programme for females. Following Joint Committee on Vaccination and Immunisation (JCVI) advice, a targeted HPV MSM vaccination pilot was introduced in GUM and HIV clinics across England from June 2016. We present plans for monitoring vaccination uptake and surveillance of infection and early disease outcomes.MethodsUptake (of three doses over a two year period) will be monitored via two existing surveillance and reporting systems: the Genitourinary medicine clinic activity dataset (GUMCADv2) and the HIV and AIDS reporting system (HARS). A seroprevalence study conducted in selected clinics for validation of these data will be considered in due course.Early impact of targeted HPV vaccination of MSM on the epidemiology of HPV infection will be detected by HPV DNA testing of rectal swabs (residual specimens following chlamydia testing) from MSM attending selected GUM clinics, starting with largely baseline collection in 2017.Expected early effects on genital warts diagnoses will be monitored (via GUMCADv2). A decline in HPV-associated cancers is not expected to be seen for some years.DiscussionA comprehensive surveillance strategy has been established to evaluate targeted HPV vaccination of MSM at GUM/HIV clinics. During the pilot, uptake will be the main outcome measure available, and surveillance systems will be established and baseline data collected to evaluate the outcomes of national implementation on infection and disease.

P071 PRE PREP PREP

IntroductionSexual health of MSM has worsened over the last decade and with NHS PREP provision on the horizon we needed to assess the current sexual health of MSM attending our small integrated sexual health clinic to ascertain who may be eligible for PREP.MethodsRetrospective case notes review of all MSM attending as a new or rebook attendance in 2015.Results140 attendances of MSM in 2015 were analysed. 136/140 (97%) had a HIV test. 36/140 (26%) were diagnosed with an STI of which 10 were rectal STIs. 62/140 (44%) had a previous STI. Documented recent unprotected anal sex occurred in 80/140 (57%), 3 patients were in a sero-discordant relationship- all had partners with an undetectable viral load. Recreational drugs were used by 9/140 (6%) of which 4 patients were engaged in chem-sex.80/140 (57%) patients would fulfil the baseline criteria for PREP.DiscussionMSM in our clinic have a high rate of STIs and more than half have had recent unprotected anal sex. There is a low rate of recreational drug use. Over half would be eligible for PREP if they continued in engage in unprotected sex. Repeated attendances through 2015 will be analysed to assess behaviour change.

O01 Recent trends in HIV diagnoses and tests among men who have sex with men attending sexual health clinics in england

IntroductionMen who have sex with men (MSM) remain at highest risk of HIV acquisition in England. We assessed recent national trends in HIV diagnoses and tests among MSM attending specialist sexual health clinics (SHCs) in England.MethodsNumbers of HIV diagnoses and tests in MSM were obtained from GUMCADv2, the national surveillance system for sexually transmitted infections. Trends were stratified by HIV testing history (new/repeat-testers in last 2 years) and service location (London/Outside-London). Student’s t-tests were used to assess the differences in mean numbers of HIV diagnoses and tests between Q4/2014–Q3/2015 and Q4/2015–Q3/2016.ResultsA decline in HIV diagnoses from 515 to 427 (17%) was observed between Q4/2014–Q3/2015 and Q4/2015–Q3/2016 (p=0.05). Greatest declines were in London SHCs (276–209; 24%; p=0.04) and among new-testers (390–308; 21%; p=0.03). In London SHCs, there was a 29% diagnosis decline among new-testers (195–138; p=0.03) with no evidence of a difference in repeat-testers (81–71; p=0.33); HIV tests in repeat-testers increased 15% (9,768–11,270; p=0.02) but remained stable among new-testers (7,166–6,638; p=0.28). In Outside-London SHCs, HIV diagnoses remained stable in new- (194–170; p=0.06) and repeat-testers (44–48; p=0.52) while HIV testing increased 14% in new- (7,679–8,734; p=0.05) and 16% in repeat-testers (7,423–8,602; p=0.02).DiscussionHIV diagnoses among MSM have decreased despite overall increased testing at SHCs. Stable levels of testing in new-testers as well as scale-up of repeat-testing may be contributing to diagnosis declines by earlier identification of undiagnosed infections. Further investigation of treatment and prevention initiatives among new- and repeat-testers in London SHCs is necessary.

Incidence and Predictors of HIV Infection Among Men Who Have Sex with Men Attending Public Sexually Transmitted Disease Clinics, New York City, 2007–2012

We examined five annual cohorts (2007-2011) of men who have sex with men (MSM) attending New York City STD clinics who had negative HIV-1 nucleic acid amplification tests (NAATs) on the day of clinic visit. Annual HIV incidence was calculated using HIV diagnoses within 1year of negative NAAT, determined by matching with the citywide HIV registry. Predictors (demographic; behavioral; bacterial STD from citywide STD registry match) of all new HIV diagnoses through 2012 were calculated from Cox proportional hazards models. Among 10,487 HIV NAAT-negative MSM, 371 had an HIV diagnosis within 1year. Annual incidence was 2.4/100 person-years, and highest among non-Hispanic black MSM (4.1/100 person-years) and MSM aged<20years (5.7/100 person-years). Characteristics associated with all 648 new HIV diagnoses included: black race (aHR 2.2; 95% CI 1.6-3.1), condomless receptive anal sex (aHR 2.1; 95% CI 1.5-2.8), condomless insertive anal sex (aHR 1.3; 95% CI 1.1-1.8), and incident STD diagnosis (aHR 1.6; 95% CI 1.3-1.9). MSM attending STD clinics have substantial HIV incidence and report risk behaviors that are highly associated with HIV acquisition. Increased uptake of effective interventions, e.g., pre- and post-exposure prophylaxis, is needed.

COBA-Cohort: a prospective cohort of HIV-negative men who have sex with men, attending community-based HIV testing services in five European countries (a study protocol).

IntroductionCommunity-based voluntary counselling and testing (CBVCT) services for men who have sex with men (MSM) can reach those most-at-risk and provide an environment for gay men that is likely to be non-stigmatising. Longitudinal data on the behaviour of HIV-negative MSM are scarce in Europe. The aim of this protocol, developed during the Euro HIV Early Diagnosis And Treatment (EDAT) project, is to implement a multicentre community-based cohort of HIV-negative MSM attending 15 CBVCT services in 5 European countries.Research objectives(1) To describe the patterns of CBVCT use, (2) to estimate HIV incidence, and to identify determinants of (3) HIV seroconversion and (4) HIV and/or sexually transmitted infection (STI) test-seeking behaviour.Methods and analysisAll MSM aged 18 years or over and who had a negative HIV test result are invited to participate in the COmmunity-BAsed Cohort (COBA-Cohort). Study enrolment started in February 2015, and is due to continue for at least 12 months at each study site. Follow-up frequency depends on the testing recommendations in each country (at least 1 test per year). Sociodemographic data are collected at baseline; baseline and follow-up questionnaires both gather data on attitudes and perceptions, discrimination, HIV/STI testing history, sexual behaviour, condom use, and pre- and post-exposure prophylaxis. Descriptive, exploratory and multivariate analyses will be performed to address the main research objectives of this study, using appropriate statistical tests and models. These analyses will be performed on the whole cohort data and stratified by study site or country.Ethics and disseminationThe study was approved by the Public Health authorities of each country where the study is being implemented. Findings from the COBA-Cohort study will be summarised in a report to the European Commission, and in leaflets to be distributed to study participants. Articles and conference abstracts will be submitted to peer-reviewed journals and conferences.
