RESUMO
BACKGROUND: Stigmatization may prompt gay, bisexual, queer and other men who have sex with men (GBQMSM) to avoid or delay HIV testing. There has been little attention to GBQMSMs' perspectives about how stigma may influence their decisions about whether, where, and how often to get tested for HIV. METHODS: We conducted nine focus groups with 64 adult GBQMSM in Metropolitan Detroit, including HIV-negative men and people living with HIV (PLWH). Data were thematically analyzed deductively and inductively in three rounds. RESULTS: Three themes emerged regarding whether to get tested: (1) Perceived promiscuity, risk perceptions and HIV testing; (2) Fearing sexual rejection; and (3) Fearing friend and family member distancing and rejection. Themes concerning where to get tested included: (4) Conflating HIV testing and diagnosis; and (5) Seeking privacy and safety at specialized services. As for how often to get tested, themes included: (6) Reducing contact with healthcare providers due to intersectional stigma; (7) Responsibility and regular testing; and (8) HIV stigma and testing as routine care. Black participants articulated themes (3), (4), and (6) with greater frequency than other participants. Framing HIV testing as a personal responsibility may have created a "new stigma," with unintended consequences not observed with "routine healthcare" messaging. CONCLUSIONS: GBQMSMs' perspectives indicate the potential for new foci for HIV testing promotion interventions based on stigma-related issues that they deem important. There is a need for interventions to challenge the "promiscuity" stereotype, and to reduce the sexual stigmatization of GBQMSM living with HIV/AIDS-especially online. Provider stigma requires both intervention and continued availability of specialized services. Future stigma-reduction interventions for Black GBQMSM could focus on building family support/acceptance, awareness of multiple testing options, and integrating LGBTQ-related issues into initiatives for racial justice in health care.

Prior research with male couples has focused on how sexual agreements can influence relationship dynamics, sexual risk taking, and health promoting behaviors. Little is known about the association between sexual agreements and the experience or perpetration of intimate partner violence (IPV) in this population. Our study sought to evaluate these associations using dyadic data from a sample of 386 male couples residing in the U.S. Both partners independently reported on their relationship characteristics, sexual agreements, and specific acts reflecting physical, emotional, controlling, and monitoring IPV in separate surveys. Participants were more likely to have experienced IPV in the past year if they were in a relationship for ≥ 3 years versus < 3 years (aOR = 1.62, 95% CI = 1.03-2.53). Among 278 couples who had formulated sexual agreements, men who concurred with their partners on being in an "open" relationship were less likely to have experienced IPV versus those in a "closed" relationship (aOR = 0.47, 95% CI = 0.25-0.89). However, participants were more likely to have experienced IPV if their partners believed they had previously broken their sexual agreement (aOR = 2.79, 95% CI = 1.03-7.52). The verbal explicitness and duration of sexual agreements were not associated with either experiencing or perpetrating IPV in the past year. However, increasing levels of depressive symptomatology were associated with a greater likelihood of both experiencing and perpetrating IPV. Our findings highlight the need to prioritize dyadic interventions for male couples that focus on skills building around enhancing mutual communication and negotiating sexual agreements to reduce IPV.

BACKGROUND: The past decade has seen increasing attention directed to the development of HIV prevention interventions for male couples, driven by epidemiological data indicating that main or primary - rather than causal - partnerships account for a substantial number of HIV infections in this population. Couples HIV testing and counseling (CHTC) has emerged as a standard of care in the US. This protocol describes a study that aims to evaluate the efficacy of two adjunct components to CHTC - communication training (CT) videos and a substance use module (SUM) - to reduce drug use and sexual HIV transmission risk behavior. METHODS: Eligible couples must include one participant who is aged 17-29, HIV-negative, and reports recent drug use. Both partners must be aged 17 or older, identify as cismale (assigned male sex at birth and currently identify as male gender), and communicate in English. Couples are randomized post-baseline to one of four conditions (CHTC as usual, CHTC plus CT video; CHTC + SUM and CHTC + CT video + SUM) in a full-factorial design. Follow up assessments are completed at 3-, 6-, 9- and 12-months post baseline. DISCUSSION: Results of this trial will enhance the application of CHTC. If found effective, adjunct components would comprise a brief and scalable drug use intervention that could be readily integrated into existing HIV testing settings. TRIAL REGISTRATION: ClinicalTrials.gov Protocol Registration; NCT05000866 ; completed August 3, 2021; https://register.clinicaltrials.gov/ Protocol version 1.0; September 1, 2021.

There is growing evidence that sexual behaviors among male couples are strongly shaped by emotional and quality characteristics of the relationship, and that the labels that men attach to their relationships may indicate how men perceive and engage in risk taking. There has been a lack of attention to how male couples label their relationships, and how discordant understandings of relationship labels may shape HIV risk behavior. Using data from a sample of 804 partnered men who have sex with men, this analysis examines associations between discordant relationship labeling and participation in HIV testing and sexual behavior. Men who labeled their relationship differently from their partners were less likely to have been recently tested for HIV and more likely to engage in sexual risk. The results underscore the need to develop interventions that provide spaces and skills for men to learn how to effectively navigate HIV risks in their relationships.

Partnered men who have sex with men are not immune to the risk of HIV. Analyzing dyadic data from 360 male couples recruited from April 2016 to June 2017, we examined how relationship characteristics might influence HIV testing behavior and perceptions of partners' HIV testing. Increasing levels of mutual trust were associated with lower odds of both partners (versus neither) having been tested in the past year (aOR = 0.91, 95% CI 0.83-0.99), but increasing levels of communal coping were associated with higher odds (aOR = 1.06, 95% CI 1.02-1.10). Only one partner was more likely to be correct about whether or not his partner had been tested in the past year (versus both) if someone had broken their sexual agreement (aOR = 2.60, 95% CI 1.17-5.76). Increasing differences in trust (aOR = 1.10, 95% CI 1.01-1.20) were also associated with higher odds of only one partner being correct. Dyadic HIV prevention efforts should incorporate skills building around negotiating sexual agreements and constructive communication.

Use of Pre-exposure prophylaxis (PrEP) for HIV prevention by men who have sex with men (MSM) may be impacted by relationship dynamics. We assessed perceived partner support of PrEP use and benefit of PrEP by relationship characteristics among male couples. Baseline data from a randomized control trial of video-based HIV counseling and testing among male couples in the U.S. were used in adjusted multilevel regression models to assess individual and dyadic characteristics. Among 659 participants, 73.3% thought their partner would be supportive of their PrEP use; 26.7% reported their partner would not support PrEP use, which was significantly associated with intimate partner violence (IPV) (p = 0.008). Most (57.7%) did not believe PrEP would be beneficial to them or their partner. Couples with a sexual agreement allowing outside partners were significantly associated with higher perceived support of partners for PrEP (p < 0.001) and benefit of PrEP use (p < 0.001). Perceived partner support of PrEP was high but perceived benefit of PrEP was low, both shaped by relationship dynamics that highlight the need for tailored dyadic interventions. The association between perceived PrEP support and IPV points to the need to integrate relationship contexts in HIV prevention programs.

Transgender youth have low rates of engagement in HIV prevention, shaped in part by experiences of transphobia and lack of access to culturally competent care. Project Moxie tested the feasibility of an intervention that provides home-based HIV self-testing coupled with video-chat counseling. A diverse sample of 202 binary and nonbinary transgender youth (TY) were recruited online, and randomized 2:1 to receive the intervention or a control condition of only home-based HIV self-testing. TY were willing to order HIV self-testing kits and report their results. Half of those in the intervention arm opted to use the video-chat counseling and, among those who did, levels of satisfaction were high. Project Moxie demonstrates the ability to recruit TY online and provide them with access to home HIV testing. Further work is required to develop online interventions for youth who do not wish to receive counseling through video-chat formats.

Sexual agreements are an important HIV risk reduction strategy enacted by men in male-male partnerships. Greater levels of relationship quality have been associated with sexual agreement formation and adherence. However, current evidence supporting the associations between relationship quality and sexual agreements for male dyads is based primarily on the responses of just one partner. Understanding that relationship quality and decisions about sexual agreements are inherently influenced by both partners, the present analysis uses dyadic-level data to examine the sexual agreements among 199 HIV serodiscordant and seroconcordant male dyads (n = 398 individuals). Specifically, the analysis examines measures of love, trust, and conflict style as they relate to (1) the type of agreement established, (2) concordance in agreement reporting, (3) satisfaction with the agreement, and (4) broken agreements. A discrepancy in love between partners was associated with the type of agreement established, whether they reported the same agreement type, and whether one of the partners reported a broken agreement, but it was not associated with either partner's satisfaction with the agreement. A discrepancy in trust was associated with agreement concordance and agreement breaks, but it was not associated with the type of agreement established or satisfaction with the agreement. Lastly, a discrepancy in conflict style was associated with each of the agreement outcomes. Future research and intervention efforts should focus on understanding the behavioral and communication skills necessary for couples to make successful sexual agreements.

Gay, bisexual and other men who have sex with men (GBMSM) experience greater health disparities, and concern about other health conditions may decrease engagement in HIV prevention. This study assessed perceived threat and impact of HIV relative to other health concerns among GBMSM. Data were from a national online survey of GBMSM conducted between August and September 2015. Participants ranked concern about contracting HIV and impact of HIV on their health compared with other health conditions. The association of HIV threat and impact with recent condomless anal sex (CAS) and HIV testing were assessed using regression models. Among 466 participants, threat and impact of HIV were ranked lower compared to cancer, Alzheimer's and heart disease. Concern about getting HIV was associated with greater odds of recent HIV testing (adjOR 1.1, 95%CI 1.02-1.18) and lower CAS (adjOR 0.86, 95%CI 0.78-0.94). Among GBMSM, other health conditions may be perceived as a greater threat and higher impact on health compared with HIV. Integrating complex health care concerns with HIV prevention strategies may increase engagement in prevention.

The American Men's Internet Survey (AMIS) is conducted annually with 10,000 men age 15 + who have sex with men (MSM). Modeling was used with 39,863 AMIS surveys from 4 cycles between December 2013 to February 2017 to identify temporal trends in sexual behavior, substance use, and testing behavior (within 12 months preceding interview) stratified by participants' self-reported HIV status. HIV-negative/unknown status MSM had significant increases in condomless anal intercourse (CAI), marijuana use, use of other illicit substances, sexually transmitted infection (STI) diagnoses, and HIV or STI testing (testing only increased among MSM age 25 +). HIV-negative/unknown status MSM had significant decrease in CAI with an HIV-positive or unknown status partner. HIV-positive MSM had significant increases in CAI, methamphetamine use, and STI diagnoses/testing. Although encouraging, the few indicators of improvement in HIV/STI sexual health practices are not consistently seen across sub-groups of MSM and may be counteracted by growing proportions of MSM engaging in CAI and acquiring STIs.

HIV/AIDS-related research requires recruitment of representative samples of MSM; yet, we know little about the comparative yield, diversity and cost-benefit tradeoffs between different recruitment venues. We compared 11 recruitment venues used for nine HIV prevention-related focus groups with MSM in Metropolitan Detroit. Of the 64 participants, 24 were clients recruited via an HIV/AIDS-focused nonprofit, 20 from Grindr advertisements, 6 from university-student email lists, and 5 from flyers/palmcards. Significantly more African-American, low-income and HIV-positive participants were recruited via the nonprofit. The best cost-benefit tradeoffs were for organizational Facebook posts, email groups, personal networking, and nonprofit recruitment. Grindr increased the size of the sample, though at greater expense. Facebook and Scruff advertisements and gay bar outreach represented greater costs than benefits. Only 11.6% of Grindr respondents attended the focus groups. A mix of online and offline recruitment venues can generate a large and diverse sample of MSM, but venue performance is uneven.

National guidelines recommend annual human immunodeficiency virus (HIV)/sexually transmitted disease testing for sexually active men who have sex with men (MSM) and vaccination against human papillomavirus for MSM through age 26. A 2012 online survey of 2,794 MSM found that 51%, 36%, and 14% reported receiving human immunodeficiency virus testing, sexually transmitted disease testing, and human papillomavirus vaccination, respectively.

DR3 (TRAMP, LARD, WSL-1, TNFRSF25) is a death-domain-containing tumor necrosis factor (TNF)-family receptor primarily expressed on T cells. TL1A, the TNF-family ligand for DR3, can costimulate T cells, but the physiological function of TL1A-DR3 interactions in immune responses is not known. Using DR3-deficient mice, we identified DR3 as the receptor responsible for TL1A-induced T cell costimulation and dendritic cells as the likely source for TL1A during T cell activation. Despite its role in costimulation, DR3 was not required for in vivo T cell priming, for polarization into T helper 1 (Th1), Th2, or Th17 effector cell subtypes, or for effective control of infection with Toxoplasma gondii. Instead, DR3 expression was required on T cells for immunopathology, local T cell accumulation, and cytokine production in Experimental Autoimmune Encephalomyelitis (EAE) and allergic lung inflammation, disease models that depend on distinct effector T cell subsets. DR3 could be an attractive therapeutic target for T cell-mediated autoimmune and allergic diseases.

BACKGROUND: A heightened proinflammatory state has been hypothesized to enhance human immunodeficiency virus type 1 (HIV-1) transmission - both susceptibility of HIV-1-exposed persons and infectiousness of HIV-1-infected persons. METHODS: Using prospective data from heterosexual African couples with HIV-1 serodiscordance, we conducted a nested case-control analysis to assess the relationship between cytokine concentrations and the risk of HIV-1 acquisition. Case couples (n = 120) were initially serodiscordant couples in which HIV-1 was transmitted to the seronegative partner during the study; control couples (n = 321) were serodiscordant couples in which HIV-1 was not transmitted to the seronegative partner. Differences in a panel of 30 cytokines were measured using plasma specimens from both HIV-1-susceptible and HIV-1-infected partners. Plasma was collected before seroconversion for cases. RESULTS: For both HIV-1-infected and HIV-1-susceptible partners, cases and controls had significantly different mean responses in cytokine panels (P < .001, by the Hotelling T(2) test), suggesting a broadly different pattern of immune activation for couples in which HIV-1 was transmitted, compared with couples without transmission. Individually, log10 mean concentrations of interleukin 10 (IL-10) and CXCL10 were significantly higher for both HIV-1-susceptible and HIV-1-infected case partners, compared with HIV-1-susceptible and HIV-1-infected control partners (P < .01 for all comparisons). In multivariate analysis, HIV-1 transmission was significantly associated with elevated CXCL10 concentrations in HIV-1-susceptible partners (P = .001) and with elevated IL-10 concentrations in HIV-1-infected partners (P = .02). CONCLUSIONS: Immune activation, as measured by levels of cytokine markers, particularly elevated levels of IL-10 and CXCL1, are associated with increased HIV-1 susceptibility and infectiousness.

Reductions in human immunodeficiency virus (HIV) incidence with pre-exposure prophylaxis (PrEP) for men who have sex with men (MSM) will require significant coverage of those at risk. We propose a simplified framework, similar to the HIV care continuum, to achieve protection with PrEP as follows: 1. At-risk MSM; 2. Awareness of and willingness to take PrEP; 3. Access to healthcare; 4. Receiving a prescription; and 5. Adhering to effective PrEP. We evaluated the PrEP care continuum on an Atlanta cohort of MSM and projected how many MSM might achieve protection from HIV. Even with optimistic estimates, few Atlanta MSM (15%) are projected to achieve protection from HIV with PrEP given the significant barriers described. Each continuum step represents an important point for intervention that could substantially increase the overall effectiveness of PrEP. In addition, novel strategies for PrEP delivery are needed to achieve the necessary effectiveness for Atlanta MSM at risk of HIV.

BACKGROUND: The commercial Kalon HSV-2 IgG ELISA is currently recommended for research use in sub-Saharan Africa because of its superior accuracy compared to other serologic assays. However, there are no data on key precision parameters of Kalon such as inter-operator variation, repeatability, and reproducibility, thus contributing to a barrier for its acceptance and use in clinical trials in sub-Saharan Africa. We evaluated the analytical and field precision of the Kalon HSV-2 IgG ELISA. METHODS: A total of 600 HIV-infected and uninfected serum samples from South Africa and Zambia, previously tested by the gold standard University of Washington HSV western blot (UW-WB), were tested using Kalon by two technologists in an United States reference laboratory. Aliquots of 183 samples were retested using Kalon by an on-site technologist in a South African laboratory and a Zambian laboratory. RESULTS: Intra-assay variation was below 10 %. Intra-assay, intra-laboratory, and inter-laboratory correlation and agreement were significantly high (p < 0.01). In comparison to the UW-WB, accurate performance of Kalon was reproducible by each operator and laboratory. Receiver operating characteristic curve analysis indicated high selectivity of Kalon in the overall study population (area under the curve = 0.95, 95%CI = 0.92-0.97). DISCUSSION: Kalon is a robust assay with high precision and reproducibility. Accordingly, operator errorlikely does not contribute to the variability observed in Kalon's specificity throughout sera from sub-Saharan Africa. CONCLUSIONS: In populations with optimal diagnostic accuracy, Kalon is a reliable stand-alone method for on-site HSV-2 IgG antibody detection.

Recent data suggest that infection with human immunodeficiency virus type 1 (HIV-1) subtype C results in prolonged high-level viremia (>5 log10 copies/mL) during early infection. We examined the relationship between HIV-1 subtype and plasma viremia among 153 African seroconverters. Mean setpoint viral loads were similar for C and non-C subtypes: 4.36 vs 4.42 log10 copies/mL (P = .61). The proportion of subtype C-infected participants with viral loads >5 log10 copies/mL was not greater than the proportion for those with non-C infection. Our data do not support the hypothesis that higher early viral load accounts for the rapid spread of HIV-1 subtype C in southern Africa.

Social media has been used widely in public health for understanding health risks and intervening to improve health. However, the utilization of social media for HIV prevention and control interventions has not been clearly characterized. We conducted a scoping review on the utilization of social media for HIV prevention and control to identify gaps in the literature and highlight opportunities for future research and intervention. A comprehensive search of seven databases was performed: PubMed, Embase, CINAHL Complete (EBSCO), PsycInfo (EBSCO), Scopus, and WOS (Science Citation Index Expanded (SCI-EXPANDED). The Preferred Reporting Items for Systematic Review and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) was used as a framework. A total of 790 articles were screened at the title and abstract level, and 78 were screened at the full-text level. Twenty-three articles met the eligibility criteria for review. We found that Facebook was still the most common social media service used to reach target populations. Lesbian, gay, bisexual and transgender (LGBT) individuals were the primary groups and were the most common targets of social media-based HIV prevention interventions. Outcomes of social media-based interventions, such as increased HIV testing, social networking and social support, condom use attitudes, behavioral skills, and research participation, were reported. Most social media-based interventions have emphasized HIV prevention, with fewer interventions focused on improving linkage to care and adherence to treatment among people living with HIV. Future studies may benefit from using social media for interventions to improve HIV-related outcomes in high-risk populations. This review highlights the potential and challenges of social media approaches for HIV/AIDS prevention and control.
RESUMO
BACKGROUND: Couples HIV testing and counseling (CHTC) is now a standard of care prevention strategy recommended by the Centers for Disease Control and Prevention for sexual minority men (SMM) in relationships. Despite standard recommendations that couples complete CHTC every 6-12 months, no study has empirically evaluated the effects associated with CHTC retesting. OBJECTIVE: This study aims to understand the benefits associated with continued dyadic engagement in the HIV prevention continuum through routine CHTC retesting, which is of particular importance for emerging-adult SMM in relationships who use drugs. METHODS: Eligible couples for this CHTC retesting trial must already be enrolled in the 4Us trial, where they completed a CHTC session after their baseline survey. The purpose of the original 4Us trial was to test the efficacy of 2 intervention components for CHTC: a communication skills training video and a substance use module. Couples were eligible for the original 4Us trial if they identified as cisgender male, were in a relationship for 3 months or longer, were aged 17 years or older, and communicated in English. At least 1 partner had to be aged 17-29 years, report HIV negative or unknown serostatus, report use of at least 1 drug (cannabis, cocaine or crack, crystal methamphetamine, ketamine, gamma-hydroxybuterate [GHB], psychedelics, ecstasy, prescription medication misuse, opiates, and nitrates) use, and engage in condomless anal sex (CAS) acts with a casual partner or have a main partner who is nonmonogamous or serodiscordant. Those who complete the 4Us 12-month follow-up and remain in a relationship with the partner they participated in 4Us with are offered the opportunity to participate in this CHTC retesting trial. Those consenting are randomized to either CHTC retesting or individual HIV testing. Follow-up assessments are conducted 3 and 6 months after randomization to evaluate the effects of repeat CHTC on 2 primary outcomes: (1) CAS with a casual partner in the absence of preexposure prophylaxis (PrEP), and (2) CAS with a serodiscordant main partner who is not virally suppressed or concurrent CAS between main and casual partners in the absence of PrEP. RESULTS: The CHTC retesting trial launched in January 2023, and enrollment is ongoing. As of February 2024, the study had enrolled 106 eligible participants (n=53 couples). CONCLUSIONS: Findings from this CHTC retesting study will contribute to knowledge about the benefits associated with regular (repeated) CHTC testing versus routine individual HIV testing for SMM in relationships. The results of this trial will inform CHTC retesting guidance. TRIAL REGISTRATION: ClinicalTrials.gov NCT05833074; htps://www.clinicaltrials.gov/study/NCT05833074.

RESUMO
BACKGROUND: Serologic studies indicate that herpes simplex virus (HSV)-1 and HSV-2 infections are highly prevalent among people infected with HIV. As an ulcerative genital disease, HSV may be important to HIV transmission and HIV-comorbidity. Routine clinical care of HSV in this population has not been described. METHODS: Data were abstracted from medical records of HIV-infected individuals by the Adult/Adolescent Spectrum of HIV Disease Project. Clinician-documented HSV diagnosis and HSV treatment, defined as any prescription for acyclovir, valacyclovir, or famciclovir, were the outcomes of interest. We present descriptive statistics and trends in HSV diagnosis and treatment. RESULTS: Between 1989 and 2004, 61,299 people were followed in this study. HSV was diagnosed in 20% of the population, and 32% of the population received HSV antiviral prescriptions. Prescriptions for episodic treatment were given to 28% of patients, and 11% received prescriptions for suppressive therapy. The average annual rate of HSV diagnosis declined by 31% during the course of the study. CONCLUSIONS: Clinically recognized HSV infections were frequent despite declining rates of diagnosis. Providers should have a high index of suspicion for HSV and consider routine screening and suppressive therapy for patients at risk of clinical disease.
