Everyday Discrimination and HIV Testing Among Partnered Latino/x Sexual Minority Men in the United States: A Stratified Analysis by Birth Location.

We examined the association between everyday discrimination and HIV testing patterns-current (≤ 6 months), recent (7-12 months), and delayed (> 12 months or never tested)-among partnered Latino/x sexual minority men (SMM). Multinomial regression analyses revealed that in the full sample (N = 484) experiencing discrimination based on sexual orientation and race/ethnicity attributions concurrently (vs. no discrimination) was associated with higher odds of delayed (vs. current) HIV testing (AOR = 2.6, 95% CI [1.0, 6.7]). Similarly, in the subset of Latino/x SMM born outside the mainland U.S. (n = 209), experiencing concurrent sexual orientation- and race/ethnicity-based discrimination (vs. no discrimination) was associated with higher odds of recent (AOR = 12.4, 95% CI [1.3, 115.7]) and delayed HIV testing (AOR = 7.3, 95% CI [1.6, 33.0]), compared with current testing. Findings suggest that addressing discrimination may improve HIV testing uptake among partnered Latino/x SMM, particularly those born outside the U.S.

Individual and Health System Factors for Uptake of Pre-exposure Prophylaxis Among Young Black and Latino Gay Men.

BACKGROUND: Young Black and Latino men who have sex with men (YBLMSM) have the highest rates of new HIV infections in the USA and use PrEP at lower rates than White MSM. OBJECTIVE: To explore YBLMSM's perspectives and experiences of PrEP use to identify factors enabling or impeding uptake. DESIGN: Qualitative study using semi-structured interviews conducted between August 2015 and April 2016. PARTICIPANTS: Black and Latino MSM, 18-20 years of age, who live, socialize, or work in the Bronx, and were fluent in English or Spanish. APPROACH: We used a thematic analysis to identify themes related to not taking PrEP and PrEP uptake. KEY RESULTS: Half the participants (n = 9) were currently using PrEP, a majority had Medicaid (n = 13), all reported having a PCP, all identified English as their primary language (n = 15), and all identified as gay. Salient themes included concerns over-side effects, stigma related to HIV and sexuality, mistrust of medical providers, provider's refusal to prescribe PrEP, and insurance and cost. CONCLUSIONS: Modifiable barriers for PrEP uptake and persistence were reported by most participants, with an emphasis on PrEP misinformation and the pervasiveness of intersectional stigma, providers' low awareness, and hesitant attitudes towards PrEP and barriers created by insurance companies. Supportive infrastructures for PrEP providers and patients are needed.

History of Incarceration is Associated with Unmet Socioeconomic Needs and Structural Discrimination among Young Black Sexual Minority Men (SMM) in the United States.

There is a dearth of research on incarceration among young Black sexual minority men (SMM). The current study aimed to assess the prevalence and association between unmet socioeconomic and structural needs and history of incarceration among young Black SMM. Between 2009 and 2015, young Black SMM (N = 1,774) in Dallas and Houston Texas were recruited to participate in an annual, venue-based, cross-sectional survey. We found that 26% of the sample reported any lifetime history of incarceration. Additionally, participants with unmet socioeconomic and structural needs (unemployment, homelessness, financial insecurity and limited educational attainment) were more likely to have a history of incarceration. It is imperative that interventions are developed to address the basic, social, and economic needs of young Black SMM with a history of incarceration or who are at risk for incarceration.

Optimizing Respondent-Driven Sampling Survey to Identify Factors Associated With HIV Risk Behaviors Among Student MSM Aged 15 to 19.

Male homosexual behavior dominates the mode of HIV infection among students in China. This study aims to identify factors associated with HIV risk behaviors among male students who have sex with men (student MSM) aged 15 to 19 in China. The online sampling used the standard respondent-driven sampling (RDS) method, with recruitment support from community-based organizations (CBOs) in Tianjin and Guangzhou. Multivariate logistic regression models were performed to identify factors associated with multiple HIV risk behaviors. A total of 449 subjects were recruited in this study, including 206 in Tianjin and 243 in Guangzhou. The presence of multiple HIV risk behaviors among student MSM, in many cases, was found to positively correlate with parental or friends' awareness of their same-sex sexual behavior or sexual orientation, with some geographical differences. The prevalence of HIV risk behaviors among student MSM aged 15 to 19 was high and associated with the disclosure of their sexual orientation or their sex with males to parents and friends. These findings highlight the importance of addressing social support in HIV prevention among student MSM when delivering HIV-related education or services.

Achieving the "Ending the HIV Epidemic in the U.S." incidence reduction goals among at-risk populations in the South.

INTRODUCTION: Antiretroviral medication coverage remains sub-optimal in much of the United States, particularly the Sothern region, and Non-Hispanic Black or African American persons (NHB) continue to be disproportionately impacted by the HIV epidemic. The "Ending the HIV Epidemic in the U.S." (EHE) initiative seeks to reduce HIV incidence nationally by focusing resources towards the most highly impacted localities and populations. This study evaluates the impact of hypothetical improvements in ART and PrEP coverage to estimate the levels of coverage needed to achieve EHE goals in the South. METHODS: We developed a stochastic, agent-based network model of 500,000 individuals to simulate the HIV epidemic and hypothetical improvements in ART and PrEP coverage. RESULTS: New infections declined by 78.6% at 90%/40% ART/PrEP and 94.3% at 100%/50% ART/PrEP. Declines in annual incidence rates surpassed 75% by 2025 with 90%/40% ART/PrEP and 90% by 2030 with 100%/50% ART/PrEP coverage. Increased ART coverage among NHB MSM was associated with a linear decline in incidence among all MSM. Declines in incidence among Hispanic/Latino and White/Other MSM were similar regardless of which MSM race group increased their ART coverage, while the benefit to NHB MSM was greatest when their own ART coverage increased. The incidence rate among NHB women declined by over a third when either NHB heterosexual men or NHB MSM increased their ART use respectively. Increased use of PrEP was associated with a decline in incidence for the groups using PrEP. MSM experienced the largest absolute declines in incidence with increasing PrEP coverage, followed by NHB women. CONCLUSIONS: Our analysis indicates that it is possible to reach EHE goals. The largest reductions in HIV incidence can be achieved by increasing ART coverage among MSM and all race groups benefit regardless of differences in ART initiation by race. Improving ART coverage to > 90% should be prioritized with a particular emphasis on reaching NHB MSM. Such a focus will reduce the largest number of incident cases, reduce racial HIV incidence disparities among both MSM and women, and reduce racial health disparities among persons with HIV. NHB women should also be prioritized for PrEP outreach.

Prevalence of Mollicutes among men who have sex with men and transgender women aged 15 to 19 years in Salvador, North-eastern Brazil.

BACKGROUND: Some species of Mollicutes have been associated with different pathologies of the urogenital tract in humans, with a high prevalence among adult men who have sex with men (MSM) and transgender women (TGW). However, few studies have been performed to investigate its prevalence among adolescents. In this study, we estimated the initial prevalence of Mycoplasma genitalium (MG), Mycoplasma hominis (MH), Ureaplasma urealyticum (UU), and Ureaplasma parvum (UP); the rate of misdiagnosis at different anatomical sites; and the associated factors with positive tests for Mollicutes among MSM and TGW aged 15 to 19 years enrolled in the PrEP1519 study. METHODS: PrEP-1519 is the first study to investigate the effectiveness of pre-exposure prophylaxis for human immunodeficiency virus among adolescent MSM and TGW aged 15 to 19 in Latin America. Oral, anal, and urethral swabs were taken from 246 adolescents upon enrolment in the study to detect MG, MH, UU, and UP by quantitative polymerase chain reaction (qPCR). Bivariate and multivariate analyses were conducted by Poisson regression and 95% confidence intervals (95% CI) were estimated. RESULTS: The prevalence of Mollicutes was 32.1%. UU was the most prevalent species (20.7%), followed by MH (13.4%), MG (5.7%), and UP (3.2%); 67.3% of the positive samples would have been missed if only urethral samples had been taken. Receptive anal sex (prevalence ratio [PR] = 1.79; 95% CI = 1.07-3.01) and clinical suspicion of sexually transmitted infection (PR = 1.62; 95% CI = 1.01-2.61) were factors associated with the detection of Mollicutes in general. Group sex (PR = 1.98; 95% CI = 1.12-3.50) and receptive anal sex (PR = 2.36; 95% CI = 0.95-5.86) were associated with the detection of Mycoplasma spp. No sociodemographic, clinical, or behavioural variable was significantly associated with the detection of Ureaplasma spp. CONCLUSIONS: A high prevalence of Mollicutes was observed among adolescent MSM and TGW, especially at extragenital sites. Further research is required to understand the epidemiological profile of high-risk adolescents in different regions and contexts, and to investigate the pathogenesis of Mollicutes in the oral and anal mucosa before routine screening can be recommended in clinical practice.

Socio-Ecological Influences on HIV Care Engagement: Perspectives of Young Black Men Who Have Sex with Men Living with HIV in the Southern US.

Young Black men who have sex with men (MSM) living with HIV evidence the lowest rates of linkage to care and viral suppression of all US MSM. Kentucky, identified by the US Department of Health and Human Services as a "hot spot" state with elevated HIV incidence compared to the rest of the country, exhibits similar racialized outcomes. Structural, interpersonal, and individual drivers of engagement along the HIV care continuum among people living with HIV have been identified, primarily through quantitative designs. However, the mechanisms by which these factors shape HIV care engagement, and the ways they may combine or reinforce each other, as well as from the lived experience of young Black MSM living with HIV, have been studied to a lesser extent. In this study, a purposive sample of n = 29 HIV-positive young Black MSM (age M = 25 years old; 38% retained in care) residing in Kentucky participated in in-depth interviews. Factors that were most influential on engagement varied along the continuum, with health insurance status and knowledge of HIV being relatively more influential to diagnosis, and housing stability, psychological processes, and interpersonal relationships being more influential on retention. For some participants, barriers to care at multiple levels had a mutually influencing and intensifying impact on care engagement. Additional efforts to center the voices of young Black MSM living with HIV will help illuminate acceptable and sustainable interventions for increasing their care engagement and narrowing persistent racial disparities in HIV morbidity and mortality.

Efficacy of MyPEEPS Mobile, an HIV Prevention Intervention Using Mobile Technology, on Reducing Sexual Risk Among Same-Sex Attracted Adolescent Males: A Randomized Clinical Trial.

Importance: HIV transmission rates in the United States have increased among men who have sex with men. However, there are no published randomized trials examining interventions to reduce sexual risk for HIV acquisition in males younger than 18 years. Objective: To determine the efficacy of MyPEEPS Mobile, a mobile-delivered HIV prevention intervention, to reduce sexual risk behavior in same-sex attracted young males. Design, Setting, and Participants: This was a national randomized clinical trial of the efficacy MyPEEPS Mobile vs a delayed intervention among males aged 13 to 18 years to prevent or reduce sexual risk for HIV acquisition. Study activities were completed through 4 study sites in Birmingham, Alabama; New York, New York; Seattle, Washington; and Chicago, Illinois. Study staff at each site met with participants in person or via video conferencing. Data were collected from June 1, 2018, to April 7, 2020, and analyzed from July to October 2021. Interventions: The MyPEEPS Mobile intervention contains 21 online psychoeducational and skill-building modules, which participants completed over a 3-month period. Participants randomized to the intervention group received access to MyPEEPS Mobile for the first 3 months, while those randomized to the delayed intervention group received access at their 9-month visit after data for the primary efficacy analysis had been collected. Main Outcomes and Measures: The self-reported primary outcome was change in the number of condomless anal sex acts between study conditions. Secondary outcomes were change in the number of sex partners, number of condomless anal sex partners, the number of sex acts while under the influence of substances, preexposure prophylactic uptake, nonoccupational postexposure prophylaxis use, and HIV and sexually transmitted infection testing. Results: In the analytic sample of 763 racially and ethnically diverse study participants, the mean (SD) age was 16.2 (1.4) years; 736 participants (97%) were male, 13 (2%) nonbinary; and 6 (1%) genderqueer; 158 (21%) were Black or African American, 311 (41%) were Hispanic or Latino, and 284 (37%) were White. Overall, 382 were randomized to the intervention group and 381 to the delayed intervention group. At 3-month follow-up, there was a significant reduction in the number of condomless anal sex acts in the intervention group compared with the delayed intervention group (incidence rate ratio [IRR], 0.56; 95% CI, 0.32-0.99); however, there was no significant difference between groups at 6 or 9 months. In subgroup analyses, the intervention effect was pronounced among Black non-Hispanic participants at 3-month follow-up (IRR, 0.19; 95% CI, 0.04-0.94) and 6-month follow-up (IRR, 0.15; 95% CI, 0.03-0.78) compared with the delayed intervention group. There were no significant differences in the change in the number of sex partners, number of condomless anal sex partners, the number of sex acts while under the influence of substances, preexposure prophylactic uptake, nonoccupational postexposure prophylaxis use, and HIV and sexually transmitted infection testing between the intervention and delayed intervention groups. Conclusions and Relevance: In this study, the MyPEEPS Mobile intervention demonstrated a 44% overall reduction in condomless anal sex at 3-month follow-up compared with the delayed intervention group, but not at 6 or 9 months. To our knowledge, MyPEEPS Mobile is the first intervention to demonstrate evidence of short-term efficacy for reducing sexual risk among same-sex attracted young males.

Encuesta en línea de comportamiento sexual y prácticas de prevención del virus de inmunodeficiencia humana en varones gais y hombres que tienen sexo con hombres en Uruguay / Web-based survey on sexual behavior and HIV prevention practices in gay men and men who have sex with men in Uruguay / Pesquisa online de comportamento sexual e práticas de prevenção do Vírus da Imunodeficiência Humana em gays e homens que fazem sexo com homens no Uruguai

Resumen: Introducción: por ser los varones gais y los hombres que tienen sexo con hombres (HSH) una población con mayor incidencia de virus de inmunodeficiencia humana (VIH), ONUSIDA recomienda el monitoreo periódico mediante encuestas que releven información para reportar indicadores de prevención. La implementación de estos estudios en nuestro medio es limitada debido a la complejidad y costos de las metodologías tradicionales. Objetivo: generar información actualizada sobre prevención del VIH, con énfasis en uso de condón y realización de pruebas de tamizaje en gais/HSH de 15 a 49 años en Uruguay, implementando una estrategia metodológica innovadora. Material y método: estudio de corte transversal y analítico, en base a una encuesta online disponible entre octubre y diciembre de 2019. Resultados: se incluyeron 693 varones, 67% de Montevideo y 67% con nivel educativo terciario. Un 17% fue forzado a mantener relaciones sexuales alguna vez, 20% sufrió maltrato por su orientación y 68,4% ocultaba su orientación sexoafectiva en algún grado. Un 57,2% usó condón en la última relación sexual anal casual, observándose un descenso respecto al año 2012 (67,6%), mientras que la tendencia en la cobertura de prueba de VIH (66%) fue creciente comparada con estudios previos. La proporción de positividad de VIH fue de 13,3%. El análisis multivariado mostró que la menor probabilidad de uso de condón se asocia a: pareja estable en el último año, autoidentificación gay, prueba de VIH en el último año y vacunación para virus papiloma humano. La mayor probabilidad de uso se asoció a: participación en actividades de información, relaciones sexuales con personas con ITS/VIH. La menor probabilidad de realización de prueba de VIH se asoció con pareja estable y la mayor con el conocimiento de lugares de acceso a prueba y conocimiento de la profilaxis posexposición. Entre quienes conocían la profilaxis preexposición (375), 46,1% estaba dispuesto a recibirla y 1,3% había accedido. Conclusiones: la persistencia de situaciones de discriminación y violencia hacia varones gais/HSH necesita acciones más efectivas de promoción de derechos. Es necesario integrar innovaciones biomédicas en prevención que se complementen y potencien para el control de la epidemia. El uso de una encuesta en línea fue eficiente en el reclutamiento, aunque con sesgos en la selección, lo que desafía a mejorar esta estrategia metodológica.

Summary: Introduction: as gay men and men who have sex with men (MSM) constitute a population with a greater incidence of HIV, UNAIDS recommends regular surveillance by means of surveys that provide information that allows reporting prevention indicators. The implementation of these studies is limited in our context given the high complexity and costs of traditional methodologies. Objectives: to generate updated information about HIV prevention, with an emphasis on condom use and to implement screening tests in gay/MSM population between 15 and 49 years old in Uruguay, using an innovative methodological strategy. Method: transversal, analytical study by means of a web-based survey available between October and December 2019. Results: 693 men were included in the study, 67% from Montevideo and 67% of which had university studies. 17% of them had been forced to have sex in the past, 20% had suffered abuse because of their sexual orientation and 68.4% concealed their sex-affective orientation to some extent. 57.2% used condoms in their last casual anal sexual relationship, what evidences a decrease with regard to 2012 (67.6%), whereas a growing tendency in the HIV test coverage (66%) was observed, when compared to previous studies. HIV positivity rate was 13.3%. The multivariate analysis revealed a lower probability of condom use was associated to: a stable partner in the last year, gay self-identification, HIV test in the last year and having the HPV vaccine. The greater likelihood of use was associated to: participating in informative activities, having sex with people with STD/HIV. The lowest probability of having an HIV test was associated to a stable partner and the highest was associated to knowing where they could get tested for HIV and also knowing about the post-exposure prophylaxis. When considering those who knew about the pre-exposure prophylaxis (375), 46.1% was willing to receive it and 1.3% had agreed to it. Conclusions: the continuation of discrimination and violence towards gay men and MSM needs more effective right promoting actions. We need to integrate into prevention biomedical innovations that complement and leverage one another. The web-based survey was effective in terms of recruiting, although there were bias in the selection, what results challenging to improve the methodological strategy.

Resumo: Introdução: como gays e homens que fazem sexo com homens (HSH) são uma população com maior incidência de HIV, o UNAIDS recomenda o monitoramento regular por meio de pesquisas que coletem informações para calcular indicadores de prevenção. A implementação desses estudos em nosso ambiente é limitada devido à complexidade e custo das metodologias tradicionais. Objetivo: gerar informações atualizadas sobre prevenção do HIV, com ênfase no uso de preservativos e testes de triagem em gays/HSH de 15 a 49 anos no Uruguai, implementando uma estratégia metodológica inovadora. Método: estudo transversal e analítico, baseado em questionário online disponível entre outubro e dezembro de 2019. Resultados: foram incluídos 693 homens, 67% de Montevidéu e 67% com nível superior. 17% foram obrigados a ter relações sexuais em algum momento, 20% sofreram maus-tratos devido à sua orientação e 68,4% ocultaram sua orientação sexual-afetiva em algum grau. 57,2% usaram preservativo na última relação anal casual, mostrando um decréscimo em relação a 2012 (67,6%), enquanto a tendência da cobertura do teste anti-HIV (66%) foi de aumento em relação a estudos anteriores. A taxa de positividade do HIV foi de 13,3%. A análise multivariada mostrou menor probabilidade de uso de preservativo associado a: parceiro estável no último ano, autoidentificação gay, teste de HIV no último ano e vacinação para papiloma vírus humano. A maior probabilidade de uso esteve associada a: participação em atividades informativas, relações sexuais com pessoas com IST/HIV. A menor probabilidade de realização do teste anti-HIV foi associada ao parceiro estável e a maior ao conhecimento dos locais de acesso ao teste e conhecimento da profilaxia pós-exposição. Entre os que conheciam a profilaxia pré-exposição (375), 46,1% estavam dispostos a recebê-la, 1,3% já haviam recebido. Conclusões: a persistência de situações de discriminação e violência contra gays/HSH requer ações mais efetivas de promoção de direitos. É necessário integrar inovações biomédicas na prevenção que se complementem e se fortaleçam para o controle da epidemia. A utilização de uma pesquisa online foi eficiente no recrutamento, embora com vieses de seleção, o que desafia a melhorar essa estratégia metodológica.

Expanding syphilis test uptake using rapid dual self-testing for syphilis and HIV among men who have sex with men in China: A multiarm randomized controlled trial.

BACKGROUND: Low syphilis testing uptake is a major public health issue among men who have sex with men (MSM) in many low- and middle-income countries. Syphilis self-testing (SST) may complement and extend facility-based testing. We aimed to evaluate the effectiveness and costs of providing SST on increasing syphilis testing uptake among MSM in China. METHODS AND FINDINGS: An open-label, parallel 3-arm randomized controlled trial (RCT) was conducted between January 7, 2020 and July 17, 2020. Men who were at least 18 years of age, had condomless anal sex with men in the past year, reported not testing for syphilis in the last 6 months, and had a stable residence with mailing addresses were recruited from 124 cities in 26 Chinese provinces. Using block randomization with blocks of size 12, enrolled participants were randomly assigned (1:1:1) into 3 arms: standard of care arm, standard SST arm, and lottery incentivized SST arm (1 in 10 chance to win US$15 if they had a syphilis test). The primary outcome was the proportion of participants who tested for syphilis during the trial period and confirmed with photo verification and between arm comparisons were estimated with risk differences (RDs). Analyses were performed on a modified intention-to-treat basis: Participants were included in the complete case analysis if they had initiated at least 1 follow-up survey. The Syphilis/HIV Duo rapid test kit was used. A total of 451 men were enrolled. In total, 136 (90·7%, 136/150) in the standard of care arm, 142 (94·0%, 142/151) in the standard of SST arm, and 137 (91·3%, 137/150) in the lottery incentivized SST arm were included in the final analysis. The proportion of men who had at least 1 syphilis test during the trial period was 63.4% (95% confidence interval [CI]: 55.5% to 71.3%, p = 0.001) in the standard SST arm, 65.7% (95% CI: 57.7% to 73.6%, p = 0.0002) in the lottery incentivized SST arm, and 14.7% (95% CI: 8.8% to 20.7%, p < 0.001) in the standard of care arm. The estimated RD between the standard SST and standard of care arm was 48.7% (95% CI: 37.8% to 58.4%, p < 0.001). The majority (78.5%, 95% CI: 72.7% to 84.4%, p < 0.001) of syphilis self-testers reported never testing for syphilis. The cost per person tested was US$26.55 for standard SST, US$28.09 for the lottery incentivized SST, and US$66.19 for the standard of care. No study-related adverse events were reported during the study duration. Limitation was that the impact of the Coronavirus Disease 2019 (COVID-19) restrictions may have accentuated demand for decentralized testing. CONCLUSIONS: Compared to standard of care, providing SST significantly increased the proportion of MSM testing for syphilis in China and was cheaper (per person tested).

Association of HIV Preexposure Prophylaxis Use With HIV Incidence Among Men Who Have Sex With Men in China: A Nonrandomized Controlled Trial.

Importance: Evidence on HIV preexposure prophylaxis (PrEP) among Chinese men who have sex with men (MSM) is critical to guide its large-scale implementation in low- and middle-income countries. Objective: To evaluate incident HIV infection, adherence, safety, and changes in sexual behaviors among MSM using daily PrEP (D-PrEP) and event-driven PrEP (ED-PrEP) in 4 cities in China. Design, Setting, and Participants: This nonrandomized controlled trial was conducted among HIV-seronegative MSM from December 11, 2018, to November 30, 2020, in Beijing, Shenyang, Chongqing, and Shenzhen. Participants self-chose D-PrEP or ED-PrEP regimens at baseline and could switch regimens during the 12-month study period. HIV-negative MSM who declined to initiate PrEP (nonusers) in the same cities joined a separate parallel prospective cohort and served as control individuals. Interventions: PrEP consisted of coformulated tenofovir disoproxil fumarate, 300 mg, and emtricitabine, 200 mg. Main Outcomes and Measures: The main outcome was incident HIV infection. Poisson regression was used to obtain the HIV incidence rate ratio (IRR). Results: A total of 1530 MSM were included in the analysis (median age, 30 [IQR, 25-37] years). At baseline, 520 MSM chose D-PrEP (median age, 29 [IQR, 25-35] years) and 503 chose ED-PrEP (median age, 29 [IQR, 25-36] years). The median HIV Risk Index score was 18 (IQR, 12-22) among D-PrEP users and 18 (IQR, 11-22) among ED-PrEP users. Among 507 PrEP nonusers, the median age was 33 (IQR, 27-43) years, and the median HIV Risk Index score was 12 (IQR, 7-18). Although PrEP users had more baseline behaviors associated with HIV risk, the HIV incidence was lower among all PrEP users (adjusted IRR, 0.09 [95% CI, 0.04-0.21]), ED-PrEP users (adjusted IRR, 0.05 [95% CI, 0.01-0.22]), and D-PrEP users (adjusted IRR, 0.12 [95% CI, 0.04-0.33]) compared with PrEP nonusers. There was no difference in HIV incidence between D-PrEP users and ED-PrEP users (IRR, 0.33 [95% CI, 0.06-2.04]). Event-driven PrEP users consumed 40% fewer tablets than D-PrEP users during the study period. Adherence, defined as the proportion of self-reported days with sexual intercourse in which PrEP was taken according to prescription of at least 90%, increased over time among ED-PrEP users (from 57.4% to 77.8%; P < .001 for trend) and decreased over time among D-PrEP users (from 75.1% to 72.1%; P = .02 for trend). Daily PrEP users reported fewer adverse events than ED-PrEP users (193 of 520 [37.1%] vs 241 of 503 [47.9%]). Conclusions and Relevance: The findings of this study suggest that D-PrEP and ED-PrEP regimens are associated with lower incidence of HIV and a good safety profile among high-risk MSM in China.

Increase in Hepatitis A Cases Linked to Imported Strains to Rio de Janeiro, Brazil: A Cross-Sectional Study.

This study aims to evaluate the epidemiological and molecular features associated with HAV transmission in adults in Rio de Janeiro during a period of increased registered cases of HAV (2017-2018). Socio-epidemiological data and serum samples from anti-HAV IgM+ individuals were obtained. HAV RNA was RT-PCR amplified and sequenced for further phylogenetic and phylogeographic analyses. From fifty-two HAV IgM+ individuals, most were men (78.85%; p = 0.024), aged 20-30 years old (84.61%; p < 0.001), resided in the Rio de Janeiro north zone (31/52; 59.62%; p = 0.001), and are men who have sex with men (MSM) (57.69%; p = 0.002). Sexual practices were more frequent (96%) than others risk factors (food-borne (44%), water-borne (42.31%), and parenteral (34.62%)). Individuals who traveled to endemic regions had a 7.19-fold (1.93-36.04; p < 0.01) increased risk of HAV. Phylogenetic analysis revealed four distinct clades of subgenotype IA, three of them comprised sequences from European/Asian MSM outbreaks and one from Brazilian endemic strains. Bayesian Inference showed that the imported strains were introduced to Brazil during large mass sportive events. Sexual orientation and sexual practices may play a role in acquiring HAV infection. Public policies targeting key populations must be implemented to prevent further dissemination of HAV and other STIs.

Mapping and size estimation of men who have sex with men in virtual platforms in Delhi, India.

INTRODUCTION: In India, the HIV epidemic is concentrated among Key Populations (KPs), such as men who have sex with men (MSM), who bear a disproportionate burden of HIV disease. Conventional targeted interventions (TI) mitigate HIV transmission among MSM by focusing on physical hotspots. As increasingly, there is a shift within India's MSM community to connect with sex partners online, novel approaches are needed to map virtual platforms where sexual networks are formed. The objective of this study was to estimate the number of MSM in Delhi using virtual platforms to connect for sex and to describe patterns of their use. METHODS: The study was conducted in the state of Delhi among MSM over 18 years of age who used virtual platforms to look for sexual partners. Virtual platforms were identified through community consultations. Size estimation was carried out by enumerating the number of online users, accounting for duplication across sites and time and based on interviews with 565 MSM. RESULTS: 28,058 MSM (95% CI: range 26,455-29,817) use virtual sites to find sexual partners. We listed 14 MSM specific virtual sites, 14 general virtual sites, 19 social networking pages and 112 messenger groups, all used by MSM. Five virtual sites met feasibility criteria to be included in the virtual mapping. Of the MSM on these sites, 81% used them at night and 94% used them on Sundays, making these the peak time and day of use. Only 16% of users were aware of organizations providing HIV services and 7% were contacted by peer educators in the preceding three months. Two-fifths (42%) also visited a physical location to connect with sexual partners in the month prior to the study. DISCUSSION: TI programs that focus on physical hotspots do not reach the majority of MSM who use virtual sites. MSM active on virtual sites have a low awareness of HIV services. Virtual mapping and programmatic interventions to include them must be incorporated into current public health interventions to reach MSM at risk of HIV.

Antimicrobial susceptibility of commensal Neisseria in a general population and men who have sex with men in Belgium.

Non-pathogenic Neisseria are a reservoir of antimicrobial resistance genes for pathogenic Neisseria meningitidis and Neisseria gonorrhoeae. Men who have sex with men (MSM) are at risk of co-colonization with resistant non-pathogenic and pathogenic Neisseria. We assessed if the antimicrobial susceptibility of non-pathogenic Neisseria among MSM differs from a general population and if antimicrobial exposure impacts susceptibility. We recruited 96 participants at our center in Belgium: 32 employees, 32 MSM who did not use antibiotics in the previous 6 months, and 32 MSM who did. Oropharyngeal Neisseria were cultured and identified with MALDI-TOF-MS. Minimum inhibitory concentrations for azithromycin, ceftriaxone and ciprofloxacin were determined using E-tests® and compared between groups with non-parametric tests. Non-pathogenic Neisseria from employees as well as MSM were remarkably resistant. Those from MSM were significantly less susceptible than employees to azithromycin and ciprofloxacin (p < 0.0001, p < 0.001), but not ceftriaxone (p = 0.3). Susceptibility did not differ significantly according to recent antimicrobial exposure in MSM. Surveilling antimicrobial susceptibility of non-pathogenic Neisseria may be a sensitive way to assess impact of antimicrobial exposure in a population. The high levels of antimicrobial resistance in this survey indicate that novel resistance determinants may be readily available for future transfer from non-pathogenic to pathogenic Neisseria.

Decrease in incidence of sexually transmitted infections symptoms in men who have sex with men enrolled in a quarterly HIV prevention and care programme in West Africa (CohMSM ANRS 12324-Expertise France).

OBJECTIVE: Although men who have sex with men (MSM) are at high risk of STI, their access to tailored healthcare services remains limited in West Africa. We assessed the change in STI symptoms incidence over time among MSM enrolled in a quarterly HIV prevention and care programme in four cities in Burkina Faso, Côte d'Ivoire, Mali and Togo. METHODS: We performed a prospective cohort study in MSM followed up between 2015 and 2019. Men aged over 18 who reported anal sex with another man within the previous 3 months were offered quarterly syndromic diagnosis and treatment for STI, as well as HIV testing, peer-led counselling and support. Condoms and lubricants were also provided. The change in STI symptoms incidence during follow-up was investigated using a non-parametric trend test and mixed-effect Poisson regression models. RESULTS: 816 participants were followed for a total duration of 1479 person-years. 198 participants (24.3%) had at least one STI symptom during follow-up. Overall, STI symptoms incidence was 20.4 per 100 person-years (95% CI 18.4 to 22.6), ranging from 15.3 in Abidjan to 33.1 in Ouagadougou (adjusted incidence rate ratio (aIRR) 2.39, 95% CI 1.55 to 3.69, p<0.001). STI symptoms incidence was 16.8 and 23.0 per 100 person-years in HIV-positive and HIV-negative participants, respectively (aIRR 0.77, 95% CI 0.57 to 1.04, p=0.087). STI symptoms incidence decreased significantly from 29.9 per 100 person-years in the first 6 months to 8.6 at 30-35 months of follow-up (aIRR per 6-month increase 0.84, 95% CI 0.77 to 0.92, p<0.001). CONCLUSION: STI symptoms incidence decreased over time but the overall burden of STI appeared to be very high in MSM followed up in West Africa. STI services including counselling, diagnosis and treatment should be reinforced. Laboratory tests that allow accurate diagnosis of STI are required. Strengthening STI services will be critical for controlling the HIV and STI epidemics in this vulnerable population and in the general population. TRIAL REGISTRATION NUMBER: NCT02626286.

Comparison of the patterns of chlamydia and gonorrhoea at the oropharynx, anorectum and urethra among men who have sex with men.

OBJECTIVE: Chlamydia and gonorrhoea are common sexually transmitted infections that infect the oropharynx, anorectum and urethra in men who have sex with men (MSM). This study aimed to examine the pattern of infection at more than one site (multisite) for chlamydia and gonorrhoea among MSM. METHODS: This was a retrospective study of MSM attending the Melbourne Sexual Health Centre for the first time between 2018 and 2019. We included MSM aged ≥16 years who had tested for Neisseria gonorrhoeae and Chlamydia trachomatis at all three sites (oropharynx, anorectum and urethra). We compared infections that occurred at a single site (termed single-site infection) and those that occurred at more than one site (termed multisite infections). RESULTS: Of the 3938 men who were tested for chlamydia and gonorrhoea, 498/3938 men (12.6%, 95% CI 11.5% to 13.6%) had chlamydia at any site, of whom 400/498 (80.3%, 95% CI 78.9% to 81.2%) had single-site chlamydia infection, and 98/498 (19.7%, 95% CI 16.2% to 23.1%) had multisite infections. A similar proportion of men had gonorrhoea at any site (447/3938, 11.4%, 95% CI 10.3% to 12.2%), but among these 447 men, single-site infection was less common (256/447, 57.3%, 95% CI 52.6% to 61.7%, p<0.001) and multisite infection (191/447, 42.7%, 95% CI 38.2% to 47.3%, p<0.001) was more common than chlamydia. There were also marked differences by anatomical site. Urethral infection commonly occurred as single sites (75/122, 61.5%, 95% CI 52.8% to 70.1%) for chlamydia but uncommonly occurred for gonorrhoea (12/100, 12.0%, 95% CI 5.6% to 18.3%, p<0.001). In contrast, anorectal infection uncommonly occurred as multisite infection for chlamydia (98/394, 24.9%, 95% CI 20.6% to 29.1%) but was common (184/309, 59.5%, 95% CI 54.0% to 64.9%, p<0.001) for gonorrhoea. CONCLUSIONS: The markedly different pattern of site-specific infection for chlamydia and gonorrhoea infections among the same MSM suggests significant differences in the transmissibility between anatomical sites and the duration of each infection at each site.

Implementation of a national HIV pre-exposure prophylaxis service is associated with changes in characteristics of people with newly diagnosed HIV: a retrospective cohort study.

OBJECTIVES: To review characteristics of individuals newly diagnosed with HIV following implementation of a national pre-exposure prophylaxis (PrEP) programme (comprehensive PrEP services, delivered in sexual health clinics) to inform future delivery and broader HIV prevention strategies. METHODS: We extracted data from national HIV databases (July 2015-June 2018). We compared sociodemographic characteristics of individuals diagnosed in the period before and after PrEP implementation, and determined the proportion of 'potentially preventable' infections with the sexual health clinic-based PrEP delivery model used. RESULTS: Those diagnosed with HIV before PrEP implementation were more likely to be male (342/418, 81.8% vs 142/197, 72.1%, p=0.005), be white indigenous (327/418, 78.2% vs 126/197, 64.0%, p<0.001), report transmission route as sex between men (219/418, 52.4% vs 81/197, 41.1%, p=0.014), and have acquired HIV in the country of the programme (302/418, 72.2% vs 114/197, 57.9% p<0.001) and less likely to report transmission through heterosexual sex (114/418, 27.3% vs 77/197, 39.1%, p=0.002) than after implementation.Pre-implementation, 8.6% (36/418) diagnoses were 'potentially preventable' with the PrEP model used. Post-implementation, this was 6.6% (13/197), but higher among those with recently acquired HIV (49/170, 28.8%). Overall, individuals with 'potentially preventable' infections were more likely to be male (49/49, 100% vs 435/566, 76.9%, p<0.001), aged <40 years (37/49, 75.5% vs 307/566, 54.2%, p=0.004), report transmission route as sex between men (49/49, 100% vs 251/566, 44.3%, p<0.001), have previously received post-exposure prophylaxis (12/49, 24.5% vs 7/566, 1.2%, p<0.001) and less likely to be black African (0/49, 0% vs 67/566, 11.8%, p=0.010) than those not meeting this definition. CONCLUSIONS: The sexual health clinic-based national PrEP delivery model appeared to best suit men who have sex with men and white indigenous individuals but had limited reach into other key vulnerable groups. Enhanced models of delivery and HIV combination prevention are required to widen access to individuals not benefiting from PrEP at present.

Factors associated with testing positive for syphilis among MSM who present as sexual contacts of syphilis from a clinic-based population.

OBJECTIVES: There has been a significant increase in syphilis in men who have sex with men (MSM) in the UK over the past 20 years. Partner notification strategies have increased the number of MSM attending STI clinics as sexual contacts of syphilis. Current guidelines suggest testing and consideration of presumptive antimicrobial treatment. Syphilis treatment with benzathine penicillin requires clinic resources, is painful and is associated with complications. It is important we consider strategies to rationalise presumptive antimicrobial use and promote antimicrobial stewardship. METHODS: We aimed to determine if there are any factors associated with having syphilis among MSM attending as sexual contacts of syphilis in a cross-sectional study. We examined the clinical records of MSM attending as sexual contacts of syphilis from January to December 2019. RESULTS: Of the 6613 MSM who attended for STI testing, 142 of 6613 (2.1%) presented as sexual contacts of syphilis. The median age was 40 years (IQR=31-51), 43 of 142 (30%) were HIV positive, 38 of 142 (27%) had been diagnosed and treated for syphilis in the past, and 11 of 142 (8%) presented with symptoms (possible lesions of primary or secondary syphilis). Thirteen (9%, 95% CI=4.4 to 13.9) tested positive for syphilis on the day of presentation. MSM who were symptomatic (genital ulcer or body rash), HIV positive or had a history of syphilis were significantly more likely to test positive for syphilis (OR=51.88, 95% CI: 3.01 to 893.14, p=0.007). CONCLUSIONS: We have shown that in our clinic-based population of MSM who presented as sexual contacts of syphilis, the factors associated with testing positive for syphilis were: having HIV, having a history of syphilis or presenting with symptoms (possible lesions of primary or secondary syphilis). These factors could be used to rationalise antibiotic treatment among MSM presenting as sexual contacts of syphilis. Further research is needed to validate this finding in other populations of MSM and people affected by syphilis.

High levels of undiagnosed rectal STIs suggest that screening remains inadequate among Black gay, bisexual and other men who have sex with men.

OBJECTIVE: To better understand rectal STI screening practices for Black gay, bisexual and other men who have sex with men (BGBMSM). FINDINGS: Although 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. CONCLUSIONS: Findings 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.

Sexual behaviours associated with incident high-risk anal human papillomavirus among gay and bisexual men.

OBJECTIVE: High-risk human papillomavirus (HRHPV) causes anal cancer, which disproportionately affects gay and bisexual men (GBM). We examined sexual behaviours associated with incident anal HRHPV in an observational cohort study of GBM in Sydney, Australia. METHODS: GBM aged 35 years and above were enrolled in the Study of the Prevention of Anal Cancer. Detailed information on sexual practices in the last 6 months, including receptive anal intercourse (RAI) and non-intercourse receptive anal practices, was collected. Anal human papillomavirus (HPV) testing was performed at the baseline and three annual follow-up visits. Risk factors for incident HRHPV were determined by Cox regression using the Wei-Lin-Weissfeld method. RESULTS: Between 2010 and 2015, 617 men were recruited and 525 who had valid HPV results at baseline and at least one follow-up visit were included in the analysis. The median age was 49 years (IQR 43-56) and 188 (35.8%) were HIV-positive. On univariable analysis, incident anal HRHPV was associated with being HIV-positive (p<0.001), having a higher number of recent RAI partners regardless of condom use (p<0.001 for both), preference for the receptive position during anal intercourse (p=0.014) and other non-intercourse receptive anal sexual practices, including rimming, fingering and receptive use of sex toys (p<0.05 for all). In multivariable analyses, being HIV-positive (HR 1.46, 95% CI 1.09 to 1.85, p=0.009) and reporting condom-protected RAI with a higher number of sexual partners (p<0.001) remained significantly associated with incident HRHPV. When stratified by recent RAI, non-intercourse receptive anal practices were not associated with incident HRHPV in men who reported no recent RAI. CONCLUSION: GBM living with HIV and those who reported RAI were at increased of incident anal HRHPV. Given the substantial risk of anal cancer and the difficulty in mitigating the risk of acquiring anal HRHPV, HPV vaccination should be considered among sexually active older GBM.
