RESUMEN
BACKGROUND: Safe and effective long-acting injectable agents for preexposure prophylaxis (PrEP) for human immunodeficiency virus (HIV) infection are needed to increase the options for preventing HIV infection. METHODS: We conducted a randomized, double-blind, double-dummy, noninferiority trial to compare long-acting injectable cabotegravir (CAB-LA, an integrase strand-transfer inhibitor [INSTI]) at a dose of 600 mg, given intramuscularly every 8 weeks, with daily oral tenofovir disoproxil fumarate-emtricitabine (TDF-FTC) for the prevention of HIV infection in at-risk cisgender men who have sex with men (MSM) and in at-risk transgender women who have sex with men. Participants were randomly assigned (1:1) to receive one of the two regimens and were followed for 153 weeks. HIV testing and safety evaluations were performed. The primary end point was incident HIV infection. RESULTS: The intention-to-treat population included 4566 participants who underwent randomization; 570 (12.5%) identified as transgender women, and the median age was 26 years (interquartile range, 22 to 32). The trial was stopped early for efficacy on review of the results of the first preplanned interim end-point analysis. Among 1698 participants from the United States, 845 (49.8%) identified as Black. Incident HIV infection occurred in 52 participants: 13 in the cabotegravir group (incidence, 0.41 per 100 person-years) and 39 in the TDF-FTC group (incidence, 1.22 per 100 person-years) (hazard ratio, 0.34; 95% confidence interval, 0.18 to 0.62). The effect was consistent across prespecified subgroups. Injection-site reactions were reported in 81.4% of the participants in the cabotegravir group and in 31.3% of those in the TDF-FTC group. In the participants in whom HIV infection was diagnosed after exposure to CAB-LA, INSTI resistance and delays in the detection of HIV infection were noted. No safety concerns were identified. CONCLUSIONS: CAB-LA was superior to daily oral TDF-FTC in preventing HIV infection among MSM and transgender women. Strategies are needed to prevent INSTI resistance in cases of CAB-LA PrEP failure.

Healthcare providers who use controlling or coercive strategies may compel short-term enactment of HIV and sexually transmitted infection prevention behaviors but may inadvertently undermine their client's motivation to maintain those behaviors in the absence of external pressure. Autonomous motivation refers to the self-emanating and self-determined drive for engaging in health behaviors. It is associated with long-term maintenance of health behaviors. We used structural equation modeling to investigate whether autonomy support was associated with increased odds of therapeutic serum levels of pre-exposure prophylaxis, through a pathway that satisfies basic psychological needs for autonomous self-regulation and competence regarding pre-exposure prophylaxis use. We also investigated whether autonomy support was associated with decreased odds of condomless anal intercourse via the same psychological needs-satisfaction pathway of autonomous self-regulation and competence regarding condom use. We tested these two theorized pathways using secondary data from a longitudinal sample of Black men who have sex with men from across three cities in the US (N = 226). Data from the sample fit the theorized models regarding the pathways by which autonomy support leads to the presence of therapeutic PrEP levels in serum (χ2 = 0.56; RMSEA = 0.04; CFI = .99, TLI = 0.98) and how it also leads to decreased odds of condomless anal intercourse (χ2 = 0.58; RMSEA = 0.03; CFI = 0.99; TLI = 0.98). These findings provide scientific evidence for the utility of self-determination theory as a model to guide intervention approaches to optimize the implementation and impact of PrEP for Black men who have sex with men.

Alcohol-using Black MSM (Men who have sex with men) are disproportionately impacted by HIV in the U.S.-particularly in the southern U.S.-despite the availability of antiretroviral therapy (ART). The purpose of this study was to summarize the current evidence on alcohol use and ART adherence among Black MSM in the U.S. and in the South and to identify future research needs. A systematic review was conducted using eight databases to identify relevant peer-reviewed articles published between January 2010 and April 2021. The authors also snowballed remaining studies and hand-searched for additional studies. Including both quantitative and qualitative studies, five published studies examined alcohol and ART adherence among Black MSM in the U.S. The search identified 240 articles, the study team reviewed 114 in full-text and determined that only five met the inclusion criteria. Three of the five included studies identified alcohol use as a barrier to ART adherence. In conclusions, the general lack of literature on HIV disparities among alcohol-using Black MSM in the U.S. (specifically in the South) indicates a critical need for research on this population's unique risks and needs to inform the development of tailored interventions.

While HIV infections among men who have sex men (MSM) have started to decline in the United States, Black MSM continue to experience disproportionate rates of HIV infection. The purpose of this secondary analysis is to examine risk perception and its influence on PrEP adherence among Black MSM from HPTN 073. Risk perception was measured using the adapted Perceived Vulnerability to HIV Scale. The associations between risk perception and PrEP adherence were tested using generalized estimation equation model for time-variant repeated measures. Risk perception was not significantly associated with PrEP adherence. These findings suggest an there was no risk compensation among PrEP users, and inconsistency in perceived risk for HIV. Future studies should investigate the rationale for long term adherence to PrEP among Black MSM.

Black gay, bisexual, and other Black sexual minority men (BSMM) continue to experience some of the largest sexual health disparities in the U.S. Engaging BSMM in PrEP is crucial to improving sexual health outcomes and reducing disparities. However, knowledge of the profiles of sexual risk and PrEP initiation among this group is limited. This study used latent class analysis toâ¯identify HIV risk andâ¯PrEPâ¯initiation patterns among BSMM in the HPTN 073 Study (n = 226). Guided by current Centers for Disease Control screening guidelines, latent class indicators included relationship status, condom use, number of sexual partners, substance use, sexually transmitted infection (STI) history, and partner HIV status. Age and PrEP initiation were used in a multinomial regression to identify correlates of class membership. Three latent classes were identified: Single, Condomless Partners, Single, Multiple Partners, and Serodiscordant Partners. Single, Condomless Partners had the highest conditional probabilities of having greater than three male partners, substance use before sex, and receiving an STI diagnosis. Serodiscordant Partners had a 100% conditional probability of condomless sex and having a male partner living with HIV. BSMM who initiated PrEP were less likely to be classified as Single, Condomless Partners than Serodiscordant Partners (AOR = 0.07, 95% CI = 0.02, 0.66). Findings support the need for culturally relevant tailored and targeted messaging for BSMM with multiple sexual risk indicators.

Accurate HIV risk assessment among men who have sex with men (MSM) is important to help providers assess risk, and target HIV prevention interventions. We sought to develop an evidence-based HIV risk assessment tool for US MSM that is inclusive of Black MSM. Data from four large longitudinal cohorts of MSM were used to develop (EXPLORE), and validate (VAX004, HPTN061, and HVTN505). These data included visits in which participants self-reported HIV risk behavior and underwent HIV testing. We developed a pooled logistic model for incident HIV infection based on self-reported risk behaviors during the 6 months before each study visit. A total of 4069 MSM were used for the development cohort, and 8047 MSM in the three validation cohorts through 2013. The final model includes age (< 35, ≥ 35); Black race and Latino ethnicity; numbers of HIV-negative anal sex partners; number of insertive or receptive anal intercourse episodes; having 1 HIV-negative partner only; self-reported substance use; and bacterial sexually transmitted infection diagnosis. The model showed good discrimination in internal validation (C-statistic = 79.5). The external validation cohorts also showed good discrimination, with C-statistics of 73.1, 71.0, 71.9 in VAX004, HPTN061, and HVTN505 respectively, and acceptable calibration. We developed and validated an HIV risk assessment tool for MSM, which showed good predictive ability, including among the largest cohort of HIV-uninfected Black MSM in the US. This tool is available online (mysexpro.org) and can be used by providers to support targeting of HIV prevention interventions such as pre-exposure prophylaxis for MSM.

Sexual and gender identity have frequently been assessed in public health research as static states. However, a substantial and growing body of evidence indicates that both identities may have greater potential for change over time than once supposed. Despite this evidence, research into adult identity change remains relatively limited. Using longitudinal data from 1553 Black men who have sex with men (BMSM) aged 18-68 years and recruited from study locations in six major cities across the country, we examined changes in sexual and gender identities over a period of 12 months. The results showed that sexual and gender identity did indeed change among adult BMSM. Additionally, we explored internalized homophobia (IH) as a potential driver of identity change and found that IH significantly impacts the degree and direction of change, with individuals who reported higher baseline IH more likely to demonstrate a shift toward a heterosexual/straight identity at 6 and 12 months. The results are discussed in light of what is known and unknown regarding identity change, and potential avenues for future research are explored.

BACKGROUND: The HIV Prevention Trials Network (HPTN) Study 073 (HPTN 073) assessed the feasibility, acceptability, and safety of preexposure prophylaxis (PrEP) for black men who have sex with men (BMSM). The purpose of this analysis was to characterize the relationship between PrEP uptake and use and incident sexually transmitted infections (STIs) among participants enrolled in HPTN 073. METHODS: A total of 226 human immunodeficiency virus (HIV)-uninfected BMSM were enrolled in 3 US cities; all participants received client-centered care coordination (C4) and were offered daily oral PrEP. Participants were followed for 12 months with STI testing (rectal and urine nucleic acid amplification test for gonorrhea and chlamydia, rapid plasma reagin for syphilis) conducted at baseline, week 26, and week 52. Logistic regression was used to examine associations between STI incidence and PrEP uptake. Generalized estimating equations were used to evaluate associations between age, PrEP acceptance, sexual behaviors, and incident STIs. RESULTS: Baseline STI prevalence was 14.2%. Men aged <25 years were more likely to have a baseline STI (25.3% vs 6.7%; odds ratio [OR], 4.39; 95% confidence interval [CI:, 1.91, 10.11). Sixty participants (26.5%) acquired ≥1 STI during follow-up; the incidence rate was 34.2 cases per 100 person-years (95% CI, 27.4, 42.9). In adjusted analyses, baseline STI diagnosis (OR, 4.23; 95% CI, 1.82, 9.87; P < .001) and additional C4 time (OR, 1.03; 95% CI, 1.00, 1.06; P = .027) were associated with having an incident STI. STI incidence was not associated with PrEP acceptance or adherence. CONCLUSIONS: While we found higher rates of STIs in younger BMSM, overall rates of STI were lower than in prior PrEP trials, with no increase over time. BMSM with STIs at PrEP initiation may require additional interventions that target STI acquisition risk. CLINICAL TRIALS REGISTRATION: NCT01808352.

Daily oral tenofovir disoproxil fumarate (TDF)-emtricitabine (FTC) is a safe and effective intervention for HIV preexposure prophylaxis (PrEP). We evaluated the performance of a qualitative assay that detects 20 antiretroviral (ARV) drugs (multidrug assay) in assessing recent PrEP exposure (detection limit, 2 to 20 ng/ml). Samples were obtained from 216 Black men who have sex with men (208 HIV-uninfected men and 8 seroconverters) who were enrolled in a study in the United States evaluating the acceptability of TDF-FTC PrEP (165 of the uninfected men and 5 of the seroconverters accepted PrEP). Samples from 163 of the 165 HIV-uninfected men who accepted PrEP and samples from all 8 seroconverters were also tested for tenofovir (TFV) and FTC using a quantitative assay (detection limit for both drugs, 0.31 ng/ml). HIV drug resistance was assessed in seroconverter samples. The multidrug assay detected TFV and/or FTC in 3 (1.4%) of the 208 uninfected men at enrollment, 84 (40.4%) of the 208 uninfected men at the last study visit, and 1 (12.5%) of the 8 seroconverters. No other ARV drugs were detected. The quantitative assay confirmed all positive results from the multidrug assay and detected TFV and/or FTC in 9 additional samples (TFV range, 0.65 to 16.5 ng/ml; FTC range, 0.33 to 14.6 ng/ml). Resistance mutations were detected in 4 of the 8 seroconverter samples. The multidrug assay had 100% sensitivity and specificity for detecting TFV and FTC at drug concentrations consistent with daily PrEP use. The quantitative assay detected TFV and FTC at lower levels, which also might have provided protection against HIV infection.

Depression is linked to a range of poor HIV-related health outcomes. Minorities and men who have sex with men (MSM), suffer from high rates of depression. The current study examined the relationship between depressive symptoms and social network characteristics among community-recruited Black MSM in HPTN 061 from 6 US cities. A social network inventory was administer at baseline and depression was assessed with the CES-D at baseline, 6, and 12-months. At baseline, which included 1167 HIV negative and 348 HIV positive participants, size of emotional, financial, and medical support networks were significantly associated with fewer depressive symptoms. In longitudinal mixed models, size of emotional, financial, and medical support networks were significantly associated with fewer depressive symptoms as was the number of network members seen weekly. In the multivariate analyses, size of medical appointment network remained statistically significant (aOR 0.89, CI 0.81-0.98). These findings highlight the importance of network support of medical care on depression and suggest the value of support mobilization.

Little is known about HIV treatment optimism and risk behaviors among Black men who have sex with men (BMSM). Using longitudinal data from BMSM in the HPTN 061 study, we examined participants' self-reported comfort with having condomless sex due to optimistic beliefs regarding HIV treatment. We assessed correlates of treatment optimism and its association with subsequent risk behaviors for HIV acquisition or transmission using multivariable logistic regression with generalized estimating equations. Independent correlates of treatment optimism included age ≥35 years, annual household income <$20,000, depressive symptoms, high HIV conspiracy beliefs, problematic alcohol use, and previous HIV diagnosis. Treatment optimism was independently associated with subsequent condomless anal sex with a male partner of serodiscordant/unknown HIV status among HIV-infected men, but this association was not statistically significant among HIV-uninfected men. HIV providers should engage men in counseling conversations to assess and minimize willingness to have condomless sex that is rooted in optimistic treatment beliefs without knowledge of viral suppression.

Characterization of structural barriers that impede the receipt of HIV prevention and care services is critical to addressing the HIV epidemic among Black men who have sex with men (BMSM). This study investigated the utilization of HIV prevention and general care services among a non-clinic-based sample of BMSM who reported at least one structural barrier to engagement in care. Proportions of participants who had received HIV prevention services and general care services in different settings were compared using Fisher's exact test and correlates of service receipt were assessed using logistic regression. Among 75 BMSM, 60% had accessed a community-based clinic, 21% had accessed a primary care setting, and 36% had accessed an acute care setting in the last 6 months. Greater proportions of participants who had accessed community-based clinics received HIV prevention services during these visits (90%) compared to those who had accessed primary care (53%) and acute care (44%) settings (p = .005). Opportunities for BMSM to receive HIV prevention interventions differed by care setting. Having access to health care did not necessarily facilitate the uptake of HIV prevention interventions. Further investigation of the structurally rooted reasons why BMSM are often unable to access HIV prevention services is warranted.

OBJECTIVES: We assessed the relation of childhood sexual abuse (CSA), intimate partner violence (IPV), and depression to HIV sexual risk behaviors among Black men who have sex with men (MSM). METHODS: Participants were 1522 Black MSM recruited from 6 US cities between July 2009 and December 2011. Univariate and multivariable logistic regression models were used. RESULTS: Participants reported sex before age 12 years with someone at least 5 years older (31.1%), unwanted sex when aged 12 to 16 years (30%), IPV (51.8%), and depression (43.8%). Experiencing CSA when aged 12 to 16 years was inversely associated with any receptive condomless anal sex with a male partner (adjusted odds ratio [AOR] = 0.50; 95% confidence interval [CI] = 0.29, 0.86). Pressured or forced sex was positively associated with any receptive anal sex (AOR = 2.24; 95% CI = 1.57, 3.20). Experiencing CSA when younger than 12 years, physical abuse, emotional abuse, having been stalked, and pressured or forced sex were positively associated with having more than 3 male partners in the past 6 months. Among HIV-positive MSM (n = 337), CSA between ages 12 and 16 years was positively associated with having more than 3 male partners in the past 6 months. CONCLUSIONS: Rates of CSA, IPV, and depression were high, but associations with HIV sexual risk outcomes were modest.

In The HIV Prevention Trials Network 061 study, 155 human immunodeficiency virus (HIV)-infected men reported no prior HIV diagnosis; 83 of those men had HIV RNA levels of <1000 copies/mL at enrollment. Antiretroviral drug testing revealed that 65 of the 83 (78.3%) men were on antiretroviral treatment. Antiretroviral drug testing can help distinguish between newly diagnosed and previously diagnosed HIV infection.

Adolescents and young adults (ages 13-24) in the USA are frequently exposed to violence in their community and home. While studies have examined the prevalence and impact of violence exposure among adolescents, there is a lack of data focusing specifically on adolescent men of color who have sex with men. Eight demonstration sites funded through a Special Projects of National Significance (SPNS) Initiative recruited 363 HIV-positive racial/ethnic minority young men who have sex with men (YMSM) for a longitudinal study between 2006 and 2009. Over two-thirds of participants (83.8%) had witnessed community violence, 55.1% in the prior three months. Witnessing violence committed with a deadly weapon was significantly associated with being African-American, having ever used drugs, and drinking alcohol in the prior two weeks. Fear of violence in the community was significantly associated with depressive symptomatology, having less than a high school degree, not possessing health insurance, and site of enrollment. Having been emotionally or physically abused by a parent or caretaker was significantly associated with depressive symptomatology, attempting suicide, site of enrollment, and increased age. Witnessing violence with a deadly weapon was significantly associated with alcohol and drug use but not with high-risk sexual behaviors. As this was one of the first studies on the prevalence and correlates of violence exposure among racial/ethnic minority YMSM living with HIV, the findings can be used to inform the development of culturally appropriate resilience-focused interventions to address the aftereffects of violence exposures and help develop social support systems outside of the family.

INTRODUCTION: HPTN 083 demonstrated the superiority of long-acting cabotegravir (CAB-LA) versus daily oral emtricitabine/tenofovir disoproxil fumarate (TDF/FTC) as pre-exposure prophylaxis (PrEP) among cisgender men and transgender women who have sex with men (MSM/TGW). HPTN 083 provided the first opportunity to understand experiences with injectable PrEP in a clinical trial. METHODS: Participants from two US sites (Chicago, IL and Atlanta, GA) and one international site (Rio de Janeiro, Brazil) were purposively sampled for individual qualitative interviews (N = 40), between November 2019 and March 2020, to explore trial experiences, barriers to adherence and other factors that may have impacted study implementation or outcomes. The blinded phase ended early due to efficacy; this analysis includes interviews conducted prior to unblinding with three groups defined by adherence (i.e. injection visit attendance): adherent (n = 27), non-adherent (n = 12) and early discontinuers (n = 1). Data were organized using NVivo software and analysed using content analysis. RESULTS: Participants (mean age: 27) were primarily cisgender MSM (90%) and Black/African American (60%). Reasons for trial enrolment and PrEP use included a preference for using HIV prevention medication versus treatment in the event of HIV acquisition; the ability to enhance health via study-related education and services; access to a novel, convenient HIV prevention product at no cost; and contributing to MSM/TGW communities through research. Participants contrasted positive experiences with study staff with their routine clinical care, and emphasized increased scheduling flexibility, thorough communication, non-judgemental counselling and open, affirming environments (e.g. compassion, less stigma) as adherence facilitators. Injection experiences were positive overall; some described early injection-related anxiety, which abated with time and when given some measure of control (e.g. pre-injection countdown), and minimal injection site discomfort. Some concerns and misperceptions about injectable PrEP were reported. Barriers to adherence, across all adherence categories, included structural factors (e.g. financial constraints, travel) and competing demands (e.g. work schedules). CONCLUSIONS: Respondents viewed injectable PrEP trial participation as a positive experience and a means of enhancing wellbeing. Study site flexibility and affirming clinic environments, inclusive of non-judgemental counselling, were key facilitators of adherence. To support injection persistence, interventions that address structural barriers and promote flexible means of injection delivery may be most effective.

Recent findings highlight the continued rise in cases of HIV infection among racial/ethnic minority young men who have sex with men (YMSM). In adults, disclosure of HIV status has been associated with decreased sexual risk behaviors but this has not been explored among YMSM. In this study of 362 HIV-infected racial/ethnic minority YMSM, rates of disclosure were high, with almost all disclosing their status to at least one person at baseline. The majority had disclosed to a family member, with higher disclosure rates to female relatives compared with males. After adjustment for site, disclosure to sex partners and boyfriends was associated with an increase in condom use during both oral and anal sex. Future studies should consider skills training to assist youth in the disclosure process, facilitate how to determine who in their family and friend social network can be safely disclosed to and support family-based interventions.

Objectives: The only available oral pre-exposure prophylaxis (PrEP) regimens approved in the United States to prevent HIV infection during the period covered by this study were emtricitabine/tenofovir alafenamide (F/TAF) and emtricitabine/tenofovir disoproxil fumarate (F/TDF). Both agents have similar efficacy, however F/TAF exhibits improved bone and renal health safety endpoints over F/TDF. In 2021, the United States Preventive Services Task Force recommended individuals have access to the most medically appropriate PrEP regimen. To understand the impact of these guidelines, the prevalence of risk factors to renal and bone health was evaluated among individuals prescribed oral PrEP. Methods: This prevalence study utilized the electronic health records of people prescribed oral PrEP between January 1, 2015 and February 29, 2020. Renal and bone risk factors (age, comorbidities, medication, renal function, and body mass index) were identified using International Classification of Diseases (ICD) and National Drug Code (NDC) codes. Results: Among 40 621 individuals prescribed oral PrEP, 62% had ≥1 renal risk factor and 68% had ≥1 bone risk factor. Comorbidities were the most frequent (37%) class of renal risk factors. Concomitant medications were the most prominent (46%) class of bone-related risk factors. Conclusions: The high prevalence of risk factors suggests the importance of their consideration when choosing the most appropriate regimen for individuals who may benefit from PrEP.
RESUMEN
Autonomy support is a concept that is derived from self-determination theory. Autonomy refers to the freedom to act as one chooses. The current study aimed to examine if autonomy support was associated with dried blood spot validated pre-exposure prophylaxis (PrEP) adherence, and whether the association was mediated by PrEP adherence goal setting and progress toward PrEP adherence goals. Our sample was drawn from Black men who have sex with men (MSM) from across three cities (Chapel Hill, NC; Los Angeles, CA; and Washington, DC) in the United States between February 2013 and September 2014. We used logistic regression to evaluate associations between study variables and path analysis to test mediation effects. Participants were, on average, 28 [standard deviation (SD) = 1.12] years old and 25% were unemployed. We found that MSM who experienced high autonomy support were more likely to adhere to PrEP [odds ratio (OR) = 1.17; 95% confidence interval: 1.00-1.38]. MSM who set PrEP adherence goals were more likely to adhere to PrEP. Moreover, MSM who reported making progress toward their goals were also more likely to adhere to PrEP. Finally, client perception of coordination quality enhanced the magnitude of the association between goal setting and goal progress and the effect size of goal progress on PrEP adherence. Autonomy support, goal setting, goal monitoring/evaluation, and care coordination quality influenced PrEP adherence among Black MSM. Our findings indicate that while it is important to set goals for PrEP adherence, goal setting may need to be accompanied by progress monitoring to achieve the maximal effect.

BACKGROUND: Black men who have sex with men (MSM) experience disproportionate rates of HIV infection in the USA, despite being no more likely to engage in sexual risk behaviors than other MSM racial/ethnic groups. HIV pre-exposure prophylaxis (PrEP) has been shown to reduce risk of HIV acquisition; however, rates of PrEP use among Black MSM remain low. Clinical, psychosocial, and structural factors have been shown to impact PrEP use and adherence among Black MSM. Care coordination of HIV prevention services has the potential to improve PrEP use and adherence for Black MSM, as it has been shown to improve HIV-related care outcomes among people living with HIV. METHODS: Client-centered care coordination (C4) is a multi-level intervention designed to address clinical, psychosocial, and structural barriers to HIV prevention services for Black MSM within HPTN 073, a PrEP demonstration project among Black MSM in three cities in the USA. The current study examined the implementation process of C4, specifically investigating the activities, cost, time, and outcomes associated with the C4 intervention. RESULTS: On average, participants engaged in five care coordination encounters. The vast majority of care coordination activities were conducted by counselors, averaging 30 min per encounter. The cost of care coordination was relatively low with a mean cost of $8.70 per client encounter. CONCLUSION: Although client-centered care coordination was initially implemented in well-resourced communities with robust HIV research and service infrastructure, our findings suggest that C4 can be successfully implemented in resource constrained communities.
