Hepatitis C treatment and behavioural risk among men who have sex with men with HIV: comparing interferon and direct-acting antiviral eras.

Little is known about the effect of HCV treatment on sexual risk behaviour among men who have sex with men (MSM) with HIV by treatment type (IFN-based vs DAA-based). MSM with HIV and recently acquired HCV infection enrolled in the observational MOSAIC cohort. Using data from 2009-2018, we evaluated risk behaviour through a validated HCV risk score (where ≥2 indicated high risk) and its individual risk behaviours. Levels of risk behaviour before, during and after treatment were modelled for each treatment episode using linear and logistic regression with Generalized Estimating Equations adjusting for DAA availability and number of re-infections. 140 MSM with a median age of 45 years (interquartile range=40-49) yielded 180 treatment episodes (n=131 IFN-based, n=49 DAA-based). Adjusted mean risk score before, during and after treatment was 2.4 (95% confidence interval (CI)=2.1-2.6), 0.9 (95%CI=0.8-1.0) and 1.7 (95%CI=1.5-1.8), respectively. Before treatment, no differences in mean HCV risk score or proportion of specific behaviours were found between the regimen groups. During treatment, MSM treated with DAAs had a higher average risk score and proportion of receptive condomless anal sex, sharing toys and unprotected fisting than those treated with IFN. After treatment, the proportion sharing straws were significantly higher in MSM treated with DAAs than IFN. MSM treated with DAAs, compared to IFN, had higher levels of HCV-related risk behaviour during treatment. The higher risk of HCV re-infection in the DAA-era underscores the need for ongoing HCV testing and behavioural interventions against HCV.

Risk of Clade II Mpox Associated with Intimate and Nonintimate Close Contact Among Men Who Have Sex with Men and Transgender Adults - United States, August 2022-July 2023.

A global outbreak of clade II mpox associated with sexual contact, disproportionately affecting gay, bisexual, and other men who have sex with men (MSM), has been ongoing since May 2022. Information on types of contact most associated with transmission is limited. This report used data from a multijurisdictional vaccine effectiveness case-control study of sexually active persons aged 18-49 years who identified as MSM or transgender, collected during August 2022-July 2023. Odds of mpox associated with selected types of intimate and nonintimate close contact with a person with mpox were estimated. Among 457 case-patients and 1,030 control patients who met minimum data requirements, 150 (32.8%) case-patients and 57 (5.5%) control patients reported close contact with a person with mpox and were included in this analysis. Adjusted odds of mpox were 5.4 times as high among those who reported having condomless receptive anal sex with a person with mpox, compared with participants who reported close contact with a person with mpox and no condomless receptive anal sex with that person (OR = 5.4; p = 0.031). Although the mpox vaccine is highly effective, vaccination coverage remains low; a multifaceted approach to prevention remains important and should include vaccination promotion, safer sex practices, and increasing awareness that mpox continues to circulate.

Campylobacter spp. in men who have sex with men: A systematic review.

Campylobacter spp. has been reported to be a sexually transmissible enteric infection in men who have sex with men (MSM) since the 1980s causing an acute severe diarrhoeal illness and rarely an acute demyelinating polyneuropathy (Guillain-Barré syndrome). The aim of this review was to explore the factors seen in MSM with Campylobacter spp. We conducted a systematic review following PRISMA guidelines by searching 7 bibliographical databases in August 2024 for manuscripts in English. Initial screening was conducted by a primary author and then two authors conducted independent full-text reviews to determine the final eligible manuscripts. We only included manuscripts which explored factors seen in MSM with Campylobacter spp.. Two authors independently used the Joanna Briggs Institute critical appraisal tools to assess risk for bias. This review was registered with PROSPERO (CRD42023464803). 25 manuscripts met the inclusion criteria that included 265 MSM with Campylobacter spp.. This review has highlighted demographic factors (living with HIV, living in urban MSM districts, HIV negative MSM using HIV-PrEP), biological factors (antimicrobial resistant Campylobacter spp., having a concurrent or previous sexually transmitted infection [Neisseria gonorrhoeae, Chlamydia trachomatis, Herpes simplex virus, Hepatitis C, Mpox] current/previous enteric infection including non-pathogenic parasites [Shigella spp., Giardia duodenalis, Cryptosporidium, Entamoeba histolytica, Salmonella spp., Entamoeba hartmanii, Entamoeba coli, Endolimax nana, Iodamoeba butchlii]) and behavioural factors (condomless receptive anal sex, oral-anal sex, oral genital sex, multiple/new sexual partners, using sex on premises venues and the internet to meet sexual partners) seen in MSM with Campylobacter spp. This review has highlighted some important demographic, biological and behavioural risk factors seen in MSM with Campylobacter spp.. These data can be used to inform future public health interventions and clinical guidelines.

Challenges recruiting and retaining people at risk for HIV who use methamphetamine in a randomized PrEP adherence trial in Seattle, WA.

Methamphetamine is associated with increased HIV risk and suboptimal adherence to pre-exposure prophylaxis (PrEP). Interventions to support PrEP adherence for people who use methamphetamine are needed. We evaluated peer navigation to support adherence among people initiating PrEP who use methamphetamine. The HIV Prevention in Methamphetamine Users (HMU!) study enrolled participants from May 2018-January 2022 in Seattle, WA, and followed them for 6 months. Surveys collected sociodemographic, drug use, and sexual behavior data at enrollment, month 3, and month 6. Dried blood spots (DBS) were collected at months 1, 3, and 6 to measure PrEP adherence. We enrolled 21 participants of a target sample of 40, of whom 20 were prescribed PrEP. Nine participants (43%) received peer navigation and 12 (57%) received standard of care or text messaging. At baseline, most participants reported at least weekly methamphetamine use (17, 81%) and condomless receptive anal intercourse (CRAI) (16, 76%). One-third reported CRAI with a partner with HIV. Among those who provided a DBS, 78% and 50% had results commensurate with ≥4 pills/week at the month 3 and 6 visit, respectively. More than half of those prescribed PrEP completed a month 6 visit (11, 55%). Retention was not associated with peer support compared to standard of care or text messaging (p = .20). We enrolled half our target sample size despite extensive recruitment efforts. As expected, participants had challenges with PrEP adherence and persistence. While peer navigation interventions should be studied further, additional interventions are likely needed to support PrEP uptake, adherence, and persistence among people who use methamphetamine.

Hepatitis C virus infection is uncommon at baseline and during follow-up among individuals using PrEP in the Dutch national PrEP programme between 2019 and 2022

ObjectivesStudies showed that men who have sex with men (MSM), including those using pre-exposure prophylaxis (PrEP), are at increased risk of hepatitis C virus (HCV) infection. We evaluated HCV prevalence...

Incidence and prevalence of hepatitis C and B infections among men who have sex with men and transgender women enrolled in a United States HIV vaccine trial.

Rising hepatitis C and B virus (HCV and HBV) rates have been reported in men who have sex with men (MSM) and transgender women (TGW). This study characterizes HCV and HBV infections longitudinally among 2,496 MSM/TGW aged 18-50 years and at risk for HIV acquisition enrolled in an HIV-1 vaccine trial in 18 U.S. cities between 2009-2013. Participants completed behavioral surveys, HIV testing, and blood collection over 24 months. Of the 2,397 participants who consented for future testing, 1,792 (74.8%) had available paired stored blood samples at baseline and a later timepoint (Month 24 [N = 999]; if unavailable, M12 [N = 775] or M15 [N = 18]). Among 1,792 participants, 98.1% were MSM, 0.8% were TGW, and the median age was 30 years (IQR 24, 40). Participants reported a median number of 3 male sex partners (IQR 1,5) within the past 3 months. Condomless insertive anal sex was reported by 55.8% and condomless receptive anal sex by 46.7%.1.3% reported injection drug use. During follow-up, 1.4% reported pre-exposure prophylaxis (PrEP) use. At baseline 11/1792 (0.61%) participants had HCV infection (HCV AB positive, RNA detectable), with all having persistent detectable RNA and chronic HCV infection at follow-up. Phylogenetic analysis showed no clusters of HCV infection. 8 participants had HCV AB positive, RNA undetectable at baseline and follow-up, representing past HCV infection with clearance; only 2 acquired HCV, which cleared over 12-24 months. At baseline, 2 participants (2/1792 = 0.11%) had positive HBsAg, indicating chronic HBV infection. Over 12-24 months, 4 (4/1790, 0.22%) developed HBsAg positivity; these participants had HBcAB positivity at baseline, thereby likely representing reactivation. There were no new HBV infections during follow-up. Among 1,792 men who have sex with men and transgender women aged 18-50 years and at risk for HIV acquisition enrolled in a U.S. HIV-1 vaccine trial, incident hepatitis C infection rates were extremely low, with no cases of incident hepatitis B infection. These rates of incident HCV infection and HBSAg positivity are lower than previously reported among MSM/TGW.

HIV Risk Behaviors and the Use of Geosocial Networking Dating Apps among Men Who have Sex with Men and Transgender Women in Lima, Peru: a Cross-Sectional Study.

Geosocial networking dating apps (GSN apps) are an increasingly widespread technology used by populations throughout the world to facilitate sexual encounters. Studies from a variety of settings suggest a possible association between GSN app use and HIV risk behaviors, including among sexual and gender minority populations such as men who have sex with men (MSM) and transgender women (TW). However, it remains unclear to what extent GSN apps play a causal role. We explored the relationship between GSN app use and sexual risk behaviors among MSM and TW in Lima, Peru by analyzing data from a multi-site cross-sectional survey assessing both general and partner-specific sexual behaviors. We performed bivariate analysis to estimate the association of GSN app use with different individual and partner-specific factors, then fit multivariable regression models adjusting for age and education. Among 741 total participants (698 MSM, 43 TW), 64% met at least one sex partner in the prior three months using a GSN app. GSN app users were significantly more likely to report engaging in HIV risk behaviors in general, including condomless receptive anal sex, group sex, transactional sex, and sex under the influence of alcohol or drugs. Having condomless anal sex with a given partner was not associated with meeting that partner via GSN app. These findings highlight GSN app users as a particularly vulnerable subpopulation among MSM and TW in Lima. GSN apps could provide a useful vehicle for targeted HIV prevention efforts for priority populations in Peru.

Racial/Ethnic Disparities in Club Drug Use, Situational Club Drug Use during Sex, and Sexual Risk Behaviors among Alcohol-Using Men Who Have Sex with Men (MSM) in San Francisco

Background Club drug use—including 3,4-Methylenedioxymethamphetamine, ketamine, crack/cocaine, hallucinogens, gamma hydroxybutyrate, volatile nitrites, and methamphetamine—has been linked to sexual risk behaviors among MSM. Few studies examine how the use of club drugs and the association between club drug use during sex and sexual risk may differ by race/ethnicity. Methods Using data from a cross-sectional study among alcohol-using MSM in San Francisco (n = 252), we examined the associations between the interaction of race/ethnicity and club drug use during sex, and the following behavioral outcomes: any condomless anal intercourse (CAI), insertive CAI, receptive CAI, and any serodiscordant sex in the past six months. All models controlled for income, HIV status, relationship status, age, and current use of a biomedical HIV prevention tool (i.e., Pre-Exposure Prophylaxis [PrEP] or antiretroviral therapy). Results There were significant racial differences in club drug use (p < 0.001) and club drug use during sex (p = 0.01). Asian/Pacific Islander (API) and Latino participants reported using club drugs the most at 78.8% and 79%, respectively. Among users of club drugs, club drug use during sex was most common among Black (100%), and Latino MSM (93%). Significant interactions between race/ethnicity and club drug use during sex were observed for CAI (p = 0.02), insertive CAI (p = 0.01), and receptive CAI (p = 0.01). API participants who used club drug during sex had higher odds of reporting CAI (aOR = 15.27, CI = 1.50–155.34), insertive CAI (aOR = 21.11, CI = 2.04–218.10), and receptive CAI (aOR = 21.11, CI = 2.04–218.10). Conclusions Given the differing rates of club drug use during sex by race/ethnicity and the role race/ethnicity plays in modifying the relationships between club drug use during sex and sexual risk behaviors, culturally-tailored interventions may be needed to address the needs of ethnically-diverse, club drug-using MSM.

Factors Associated with Having both Male and Female Recent Sexual Partnerships Among Men Who Have Sex with Men in Harare and Bulawayo, Zimbabwe.

To better understand male and female sexual partnerships among men who have sex with men (MSM), we used data from a 2019 biobehavioral survey among MSM in Harare and Bulawayo, Zimbabwe to conduct bivariate analyses and multivariable logistic regression to determine whether sociodemographic characteristics and HIV-related factors were associated with having both male and female sexual partnerships within the last 6 months. Of included MSM (N = 1143), 31% reported both male and female partnerships in the last 6 months. Being married/cohabiting (adjusted odds ratio (aOR) = 8.58, 95% confidence interval (CI) = 4.92-14.95) or separated/divorced/widowed (aOR = 1.96, 95% CI = 1.24-3.08) vs. being single, and hazardous alcohol consumption (aOR = 1.58, 95% CI 1.19-2.09) were associated with higher odds of having both male and female recent partnerships. Being aged 35 + vs. 18-24 (aOR = 0.50, 95% CI = 0.31-0.81), condomless receptive anal intercourse at last sex with the main male partner (aOR = 0.43, 95% CI = 0.26-0.74), and positive HIV status (aOR = 0.46, 95% CI = 0.31-0.67) were associated with lower odds of recent male and female partnerships. MSM in Harare who reported harassment/abuse (aOR = 3.16, 95% CI = 1.72-5.79) had higher odds of both male and female partnerships than MSM in Bulawayo reporting harassment/abuse. The prevalence of both male and female recent partnerships (31%) was lower among MSM in this survey than in other biobehavioral surveys of MSM in sub-Saharan Africa. Findings suggest that MSM with recent male and female partnerships compared to MSM with only male recent partners have lower odds of positive HIV status and participate in behaviors that lower HIV risk; however, the direction of these relationships cannot be determined due to the cross-sectional nature of the data. The findings also suggest a possible connection between experiences of stigma of MSM behavior and not having both male and female partnerships that warrants further exploration. Accessible, stigma-free HIV testing and education programming that considers the potential overlap between the MSM and general populations via both male and female partnerships and the associated behaviors could be a key component of HIV elimination in Zimbabwe.

Extragenital Sexually Transmitted Infections Among High-Risk Men Who Have Sex With Men in Johannesburg, South Africa.

In South Africa, extragenital etiological sexually transmitted infection (STI) screening among men who have sex with men (MSM) is not routinely available. We aimed to determine the prevalence of STI pathogens at rectal and pharyngeal sites, syphilis seroprevalence, and associated risk factors among a selection of high-risk MSM without symptomatic urethritis attending a men's health clinic in Johannesburg, South Africa. A cross-sectional study was conducted in 2022. Enrolled clients self-reported demographic, sexual behavioral risks, and clinical information. Client or clinician-collected rectal and pharyngeal swabs were tested for Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma genitalium, and Trichomonas vaginalis. C. trachomatis-positive rectal samples were reflex tested for lymphogranuloma venereum. Blood specimens were screened for syphilis. Univariate and multivariate regression models were used to determine factors independently associated with the presence of an extragenital STI or syphilis. Among the 97 participants (median age, 29 years), 24.7% had an extragenital STI and 9.4% had high nontreponemal antibody titers (rapid plasma reagin ≥1:16). Rectal STIs were detected in 26.4% participants: N. gonorrhoeae (14.3%), C. trachomatis (9.9%), and M. genitalium (5.5%). Pharyngeal STIs were less prevalent (4.1%). Overall, the prevalence of any STI was 41%. Sex under the influence of drugs (adjusted odds ratio, 4.94; 95% confidence interval, 1.56-15.69) and engaging in condomless receptive anal intercourse with a casual partner (adjusted odds ratio, 8.36; 95% confidence interval, 1.73-40.28) were independent risk factors for having an extragenital STI. The high burden of extragenital STIs and active syphilis in asymptomatic MSM underscores the importance of routine etiological screening in this key population, as the syndromic approach would not enable detection or treatment of these infections.

Gender Identity Stigma in Transgender Women Is Higher After Gender-Affirming Vaginoplasty.

Gender affirmation may reduce stigma and gender-based discrimination that drive increased behaviors that can lead to HIV in transgender women (TW). For many TW, vaginoplasty is gender affirming, yet has not been previously evaluated with regard to likelihood of HIV. This pilot study of TW aimed to evaluate the influence of gender-affirming vaginoplasty on stigma and the drivers of HIV acquisition. Adult TW without HIV were recruited. Interviewer-administered surveys were used to assess demographics, gender identity stigma, psychosocial factors, importance of and satisfaction with gender affirmation, and behaviors that increase the likelihood of HIV in TW who had either undergone gender-affirming vaginoplasty (TWWV) or who had not (TWWOV). Statistical analysis was conducted using descriptive statistics, Fisher's exact tests, and Wilcoxon rank-sum tests. Thirty TW without HIV (19-83 years old) participated (TWWV = 10; TWWOV = 20). The majority identified with ethnic minority groups (n = 21, 70%) and on gender-affirming hormone therapy (n = 25, 83%). Gender identity stigma (38.0; 32.15, p = .03) and social oppression (53.6; 39.4, p = .05) scores were significantly higher among TWWV compared with TWWOV. Satisfaction with body (3.10; 1.95, p = .01), appearance (3.10; 2.10, p = .02), and femininity (3.40; 2.25, p = .001) were higher among TWWV than TWWOV. Present (n = 8, 27%) and past (n = 16, 53%) survival sex work, multiple sex partners (n = 16, 53%), and receptive condomless anal intercourse (n = 10, 33%) were reported but did not vary significantly between groups. Behaviors that may lead to HIV acquisition and their underlying drivers, including gender identity stigma, are present after gender-affirming vaginoplasty. As this procedure continues to increase among TW, interventions to mitigate chances of HIV acquisition are critically needed in this population.

Latent Class Analysis of Online Platforms for Partner-Seeking and Sexual Behaviors Among Men Who Have Sex with Men from Central Kentucky.

Little is known whether engagement in sexual behaviors associated with potential HIV risks differs by subgroups of men who have sex with men (MSM), who are distinct regarding patterns of use of online tools for partner-seeking. Using latent class analysis, we revealed four classes of app-using MSM (n = 181, 18-34 y.o., 82.4% identified as White and non-Hispanic) residing in Central Kentucky: the Grindr/Tinder class; the Poly App Use class of MSM-oriented apps; the General Social Media class, and the Bumble class. Unadjusted penalized logistic regressions showed associations of the Poly App Use class with increased numbers of receptive anal sex partners and reporting condomless receptive anal sex. Adjusting for other covariates, poly app users versus others were more likely to be older (25-34 vs. 18-24, AOR = 3.81, 95%CI = 1.70-9.03), to report past six-month illicit drug use (AOR = 2.93, 95%CI = 1.25-7.43) and to have ever used pre-exposure prophylaxis (AOR = 2.79, 95%CI = 1.10-7.12). Poly app users had behavior profiles associated with an elevated HIV risk and also reported HIV-related protective behaviors likely indicating increased risk awareness among this class. Our findings warrant differentiation of behavior profiles by patterns of app use and suggest not to generalize sexual behaviors associated with potential HIV risks to all app-using MSM.

Effectiveness of Linkage to Care and Prevention Interventions Following HIV Self-Testing: A Global Systematic Review and Meta-analysis.

Over 38.4million people were living with HIV globally in 2021. The HIV continuum includes HIV testing, diagnosis, linkage to combined antiretroviral therapy (cART), and retention in care. An important innovation in the HIV care continuum is HIV self-testing. There is a paucity of evidence regarding the effectiveness of interventions aimed at linking self-testers to care and prevention, including pre-exposure prophylaxis (PrEP). To bridge this gap, we carried out a global systematic review and meta-analysis to ascertain the effectiveness of interventions post-HIV self-testing regarding: (1) linkage to care or ART, (2) linkage to PrEP, and (3) the impact of HIV self-test (HIVST) interventions on sexual behaviors. We searched PubMed, Web of Science, SCOPUS, Cochrane Library, CINAHL Plus (EBSCO), MEDLINE (Ovid), Google Scholar, and ResearchGate. We included only published randomized controlled trials (RCTs) and quasi-experiment that compared HIVST to the standard of care (SoC). Studies with sufficient data were aggregated using meta-analysis on RevMan 5.4 at a 95% confidence interval. Cochrane's Q test was used to assess heterogeneity between the studies, while Higgins and Thompson's I2 was used to quantify heterogeneity. Subgroup analyses were conducted to identify the source of heterogeneity. Of the 2669 articles obtained from the databases, only 15 studies were eligible for this review, and eight were included in the final meta-analysis. Overall, linkage to care was similar between the HIVST arm and SoC (effect size: 0.92 [0.45-1.86]; I2: 51%; p: 0.04). In the population subgroup analysis, female sex workers (FSWs) in the HIVST arm were significantly linked to care compared to the SoC arm (effect size: 0.53 [0.30-0.94]; I2: 0%; p: 0.41). HIVST interventions did not significantly improve ART initiation in the HIVST arm compared to the SoC arm (effect size: 0.90 [0.45-1.79]; I2: 74%; p: < 0.001). We found that more male partners of women living with HIV in the SoC arm initiated PrEP compared to partners in the HIVST arm. The meta-analysis showed no difference between the HIVST and SoC arm regarding the number of clients (effect size: - 0.66 [1.35-0.02]; I2: 64%; p: 0.09) and non-clients FSWs see per night (effect size: - 1.45 [- 1.45 to 1.38]; I2: 93%; p: < 0.001). HIVST did not reduce the use of condoms during insertive or receptive condomless anal intercourse among MSM. HIVST does not improve linkage to care in the general population but does among FSWs. HIVST intervention does not improve linkage to ART nor significantly stimulate healthy sexual behaviors among priority groups. The only RCT that linked HIVST to PrEP found that PrEP uptake was higher among partners of women living with HIV in the SoC arm than in the HIVST arm. More RCTs among priority groups are needed, and the influence of HIVST on PrEP uptake should be further investigated.

Changes in Inflammatory Cytokine Levels in Rectal Mucosa Associated With Neisseria gonorrheae and/or Chlamydia trachomatis Infection and Treatment Among Men Who Have Sex With Men in Lima, Peru.

Neisseria gonorrheae and Chlamydia trachomatis are associated with mucosal inflammation and human immunodeficiency virus 1 (HIV-1) transmission. We assessed levels of inflammatory cytokines in men who have sex with men (MSM) with and without rectal gonorrhea and/or chlamydia in Lima, Peru. We screened 605 MSM reporting condomless receptive anal intercourse for rectal N. gonorrheae/C. trachomatis using nucleic acid testing. We identified 101 cases of gonorrhea and/or chlamydia and randomly selected 50 N. gonorrheae/C. trachomatis positive cases and matched 52 negative controls. We measured levels of IL-1β, IL-6, IL-8, and TNF-α in rectal secretions. Tests for HIV-1, rectal N. gonorrheae/C. trachomatis, and mucosal cytokines were repeated after 3 and 6 months. Cytokine levels in cases and uninfected controls were compared using Wilcoxon rank-sum tests and linear regression. MSM with gonorrhea/chlamydia had elevated levels of all cytokines in rectal mucosa compared with matched controls (all P values <.001). Following antibiotic treatment there were no significant differences in cytokine levels at 3- or 6-month follow-up evaluations (all P values >.05). Rectal gonorrhea/chlamydia infection is associated with transient mucosal inflammation and cytokine recruitment. Our data provide proof of concept for rectal sexually transmitted infection screening as an HIV prevention strategy for MSM. Clinical Trials Registration. NCT03010020.

Risky sexual practices and hepatitis C viremia among HIV-positive men who have sex with men in Taiwan.

Understanding the risk behaviors associated with sexually-transmitted hepatitis C virus (HCV) infection among men who have sex with men (MSM) may inform the public health policies and interventions aiming to achieve HCV microelimination. HIV-positive MSM who had one of the following conditions were enrolled to undergo face-to-face questionnaire interviews to collect information on their sexual practices in the past 12 months: (1) elevation of aminotransferases in the past 6 months; (2) acquisition of sexually transmitted infections in the past 6 months; and (3) previous HCV infections. Plasma HCV RNA were tested at enrolment and every 3 months during follow-up. Baseline characteristics and risky behaviors were compared to identify factors associated with HCV viremia between HCV-viremic MSM and HCV-aviremic MSM in multivariate analysis. Among 781 MSM with a median age of 36 years, 57 (7.3%) had HCV viremia and 724 (92.7%) no HCV viremia during follow-up. A high proportion (38.9%) of the participants reported having used recreational drugs in the past 12 months, with 34.4% of them having slamming, but only 4.8% reported having shared their injection equipment. In multivariate analysis, use of recreational drugs (adjusted odds ratio [aOR], 2.14; 95% CI, 1.16-3.96), having participated in group sex (aOR, 2.35; 95% CI 1.24-4.40) and having had condomless receptive anal intercourse (aOR, 1.97; 95% CI 1.07-3.62) were significantly associated with HCV viremia. Among high-risk HIV-positive MSM, use of recreational drugs and risky sexual contacts were associated with HCV viremia, suggesting the mucosal contacts as the major route of HCV transmission.

Correlates of HIV Infection among Men who have Sex with Men in Mvita Sub-County, Mombasa County, Kenya

Purpose: The broad objective of the study was to determine the correlates of HIV infection among men who have sex with men in Mvita sub-county, Mombasa County, by December 2020.&#x0D; Methodology: Descriptive cross-sectional study design using quantitative methods was used to collect data from a study population which included 121 HIV positive and 119 HIV negative MSM. The respondent-driven sampling (RDS) was used to obtain the sample of respondents while chi-square and multivariable logistic regression were used to identify the variables which were associated with HIV infection. Data generated from the questionnaires was collected, cleaned, coded and analyzed using STATA software Version 17. Level of significance was fixed at p=0.05, with a 95% confidence interval.&#x0D; Findings: Majority of the MSM (51%) were between 19-29 years, were single (71%), were christian (60%) had attained primary education (45%), were working (63%), 55% had an income of less than Ksh. 5000 but only 38% were married to a female. Majority (91%) of HIV negative MSM accessed PEP/PrEP and only 70% used PEP/PrEP for HIV prevention. However, majority (60%) of HIV positive MSM had anal sex with multiple casual male partners, 49% sometimes had condomless insertive anal sex while 49% had condomless receptive anal sex. HIV positive MSM also had anal sex more than once while high on alcohol (41%), always used drugs before engaging in anal sex (33%) and were non-adherent to ARVs, PrEP/PEP due to lack of transport (66%), alcohol use (24%), and drug use (15%), among other factors.&#x0D; Unique Contribution to Theory, Practice and Policy: From the study findings, the Government/NGO must address the MSM issues for instance, by increasing the number of HIV programmes targeting MSM, adequately funding them and actively engaging the MSM in running the them. Also, by sensitizing the communities, human right groups, religious leaders, politicians and other stake holders on matters pertaining MSM and lobbying for the review of the laws that criminalizes same sex relationship.

Adult Attachment Anxiety Is Protective Against the Effects of Internalized Homophobia on Condomless Sex Among Young Sexual Minority Men: The P18 Cohort Study

ABSTRACT Internalized homophobia, or the internalization of negative attitudes toward one’s sexual minority identity, is associated with sexual risk behaviors among young sexual minority men (YSMM). However, the formation and maintenance of secure or insecure socio-emotional bonds with friends, family members, and intimate partners (i.e., adult attachment) may mitigate or exacerbate the negative effects of exposure to internalized homophobia. Nevertheless, little is known about how adult attachment influences the association between internalized homophobia and sexual risk behaviors (e.g., condomless anal sex) among YSMM. Thus, this study examined the potential moderating effect of adult attachment on the association between internalized homophobia and condomless anal sex (CAS) behaviors (i.e., insertive CAS and receptive CAS) among a sample of N = 268 YSMM who participated in the study between June 2015-March 2017 using zero-inflated Poisson regression models. We found that adult attachment anxiety, but not adult attachment avoidance, significantly moderated the association between internalized homophobia and receptive CAS behaviors such that those higher on adult attachment anxiety and internalized homophobia had fewer receptive CAS events over the preceding 30 days as compared to those lower on adult attachment anxiety and internalized homophobia. Research efforts should focus on unpacking the complex associations between adult attachment, internalized homophobia, and sexual risk behaviors among YSMM.

Drug use typology, demographic covariates, and associations with condomless anal sex: A latent class analysis among a U.S. national cohort of men who have sex with men.

Prior research has shown that men who have sex with men (MSM) who use drugs are at increased risk of sexually transmitted infections (STI) and Human Immunodeficiency Virus (HIV). Often, MSM who use drugs use multiple substances at once and research has indicated that certain substances are used in combination more frequently. As a vulnerable population, it is important to understand the various ways in which this population uses drugs in order to structure prevention, harm reduction, and treatment programs to their needs. Data for this analysis were taken from a cohort of geographically diverse U.S. national sample of cisgender men who have sex with men (n = 6111). After assessing prevalence of drug use in the sample, we used iterative latent class analysis to determine substance use classes for 10 substances. After a model was selected, class assignments were examined for association with mean number of insertive and receptive condomless anal sex (CAS) partners in the past three months. The final model indicated six latent classes: class 1="cannabis use" (n=1,996), class 2="diverse use" (n=299), class 3="cocaine and inhalant use" (n=421), class 4="methamphetamine, GHB, and inhalant use" (n=345), class 5="no use" (n=2431), class 6="sedative use" (n=619). Age, race, annual income, residence in EHE jurisdictions, past history of houselessness, and past history of incarceration was significantly associated with membership in some classes. In outcome modeling, participants best assigned to Class 4 had the highest mean number of insertive (Mean=9.70, 95% CI: 5.92 - 13.47) and receptive (Mean=8.71, 95% CI: 6.75 - 10.66) condomless anal sex (CAS) partners in the prior three months. The six heterogenous classes may indicate discrete typologies of use behavior corresponding to different settings or activities, which may themselves differ by regional HIV incidence trends and participant demographics. Programs seeking to address substance use among MSM may be well served to tailor toward these divergent clusters of substance use.

Inadequate performance of a risk score to predict asymptomatic Neisseria gonorrhoeae and Chlamydia trachomatis infection among cisgender men who have sex with men

ObjectivesEpidemiological treatment of persons who are sexual contacts to partners with Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) often results in treatment of uninfected persons, which may increase the risk...

Incidence of abnormal anal cytology in HIV-infected and HIV-uninfected men who have sex with men.

Anal cytology is used in the prevention of anal cancer, which disproportionally affects men who have sex with men (MSM). Data on the incidence of cytologic abnormalities in these individuals are scant. MSM with baseline negative anal cytology and at least one further adequate cytology were included. Incidence rate for positive atypical squamous cells of undetermined significance (ASC-US+) was calculated. Kaplan-Meier curves were compared by log-rank test according to HIV status, baseline high-risk human papillomavirus (HPV) (high-risk HPV-negative, HPV16-positive, other high-risk HPV-positive [non-HPV16]) and high-risk HPV persistence (positive from baseline to the first ASC-US+or last visit for those who remained cytologically negative). Cox univariate and multivariate analyses were performed. A total of 250 MSM were included: 52/153 (34.0%) HIV-uninfected MSM had an ASC-US+report at follow-up (incidence: 13.1 × 100 person-years; 95% CI, 9.8-17.2); 48/97 (49.5%) HIV-infected MSM developed cytologic abnormalities (incidence: 16.0 × 100 person-years; 95% CI, 11.8-21.2). ASC-US+incidence in HIV-uninfected and HIV-infected MSM did not differ significantly (p=.32). Kaplan-Meier curves did not differ significantly according to baseline high-risk HPV. Differences were significant between those with and without persistent high-risk HPVs, both among HIV-uninfected (p=.03) and HIV-infected MSM (p=.008). Age (adjusted hazard ratio [aHR], 0.98; 95% CI, 0.96-0.99), high-risk HPV persistence (aHR, 1.57; 95% CI, 1.02-2.39), and condomless receptive anal sex (aHR, 1.99; 95% CI, 1.31-3.03) were predictors for incident ASC-US+. Despite the limited number of subjects, in our study HIV-uninfected and HIV-infected MSM have a similar ASC-US+incidence. Occurrence of ASC-US+ was significantly affected by age, high-risk HPV persistence, and condomless receptive anal sex. The assessment of HPV persistence might identify those MSM at higher risk for anal lesions.
