Background Whoonga is a smoked heroin-based street drug that first emerged in South Africa a decade ago. While previous scientific reports suggest that use is growing and youth are particularly vulnerable, trajectories of initiation are not well characterized. Methods In 2015, 30 men undergoing residential addiction treatment for this smoked heroin drug in KwaZulu-Natal, South Africa participated in semi-structured interviews about their experiences using the drug. Interview data were coded using qualitative content analysis. Results Participant trajectories to initiating smoked heroin were “vertical” in the context of marijuana use or “horizontal” in the context of other hard drug use. Participants reporting vertical trajectories began smoking heroin as youth at school or in other settings where people were smoking marijuana. Several participants with horizontal trajectories started smoking heroin to address symptoms of other drug or alcohol addiction. Social influences on initiation emerged as an overarching theme. Members of participants’ social networks who were smoking or distributing heroin figured prominently in initiation narratives. Surprisingly, references to injection drug use were absent from initiation narratives. Participants reported people who smoke heroin differ from those who inject heroin by race. Conclusion Consistent with theories implicating social and structural influences on substance use initiation, people who started smoking heroin had social contacts who smoked heroin and frequented places where substance use was common. Smoked heroin initiation for several participants with horizontal trajectories may have been averted if they accessed evidence-based treatments for stimulant or alcohol use disorders. With increasing reports of heroin use across Africa, a coordinated approach to address this growing epidemic is needed. However, because smoked heroin and injection heroin use occur in distinct risk environments, interventions tailored to people who use smoked heroin will be needed to prevent smoked heroin use, prevent transition to injection use, and mitigate other social harms.

There is a high prevalence of stimulant use among HIV-infected individuals, which is associated with suboptimal antiretroviral therapy (ART) adherence, HIV treatment interruptions, detectable HIV viral load, and transmission of HIV via increased sexual risk behavior. Contingency management (CM) is an initially effective treatment for stimulant use. However, the effects of CM are not sustained after the active intervention has ended. One potential contributor to the intractability of existing treatments may be a lack of attention to replacement activities or the role of depressed mood. Behavioral activation (BA) is an evidence-based approach for depression that involves identifying and participating in pleasurable, goal-directed activities. As a potential approach to address the CM rebound effect - informed by our formative qualitative research with the participant population - we conducted an open pilot trial of an intervention combining CM-BA for HIV-infected individuals with stimulant use disorder. Participants completed weekly BA therapy sessions (10–16 sessions) and thrice-weekly toxicology screenings (12 weeks); contingencies were rewarded for negative toxicology tests to support reengagement into positive life activities. Major assessments were conducted at baseline, 3-, and 6-months. Toxicology screening was repeated prior to the 6-month assessment. Eleven participants with stimulant use disorder enrolled; 7 initiated treatment and completed the full intervention. The mean age was 46 (SD = 5.03) and 14% identified as a racial/ethnic minority. Of the completers, the mean change score in self-reported stimulant use within the past 30 days (within-person change; reduction in self-reported stimulant use) was 4.14 days at 3 months and 5.0 days at 6 months [Cohen’s d = 0.89]. The mean change score in weekly toxicology screens (reduction in positive toxicology screens) was .71 at 3 months and 1 at 6 months [Cohen’s d = 1.05]. Exit interviews indicated that the integrated intervention was well received and acceptable. This study provides preliminary evidence that a combined CM-BA intervention for this population was feasible (100% retention at 6-months), acceptable (100% of intervention sessions attended; participants rated the intervention ‘acceptable’ or ‘very acceptable’), and may be an option to augment the potency and sustained impact of CM for this population. Future pilot testing using a randomized controlled design is warranted.

PURPOSE: There have been significant biomedical improvements in the treatment and prevention of HIV over the past few decades. However, new transmissions continue to occur. Alcohol use is a known barrier to medication adherence and consistent condom use and therefore may affect treatment as prevention (TasP) efforts. The purpose of this study was to further explore how alcohol is associated with condom use and sexual transmission behavior in three international cities. METHOD: HIV Prevention Trials Network 063 was an observational mixed-methods study of HIV-infected patients currently in care in Rio de Janeiro, Brazil; Chiang Mai, Thailand; and Lusaka, Zambia. Across these three global cities, 80 qualitative interviews were conducted from 2010 to 2012. From these interviews, quotes related to substance use, almost all of which were alcohol, were analyzed using thematic analysis to identify how the use was related to sexual transmission behaviors. RESULTS: Overall, the theme that alcohol impairs cognitive abilities emerged from the data and included the following subthemes: expectancies, impaired decision-making, loss of control, and less concern for others. Themes specific to international settings and risk subgroups were also identified. CONCLUSION: Our analysis identified how alcohol influences sexual transmission behavior in HIV patients in three international settings. These findings may provide direction for content development for future secondary prevention interventions to effectively implement TasP internationally.

The use of recreational drugs while having sex is associated with increased HIV incidence among men who have sex with men (MSM). Taking a daily antiretroviral pill, or pre-exposure prophylaxis (PrEP) is a biomedical intervention to prevent HIV. However, the efficacy of PrEP is closely tied with high levels of adherence. While PrEP has the potential to reduce HIV acquisition, the use of recreational drugs may impede adherence. We explored perceptions of PrEP utilization and regimen preferences among 40 HIV-negative, MSM who reported concurrent recreational drug use and condomless anal sex with a man. Semi-structured qualitative interviews were conducted and the data were analyzed using a qualitative descriptive approach. Participants perceived that it would be challenging to take PrEP while high on crystal meth, crack, powder cocaine, ecstasy and/or GHB. However, men identified strategies for using PrEP when they were not high on these drugs, including taking the pill when they started their day and integrating PrEP into an established routine, such as when taking other medications or preparing for sex. PrEP regimen preferences seemed to be shaped by the frequency in which participants used drugs and their ability to plan for sex. Taking PrEP everyday was appealing for those who regularly engaged in sexualized recreational drug use. Accounts depict these sexual interactions as frequent but unpredictable. A daily regimen would allow them to be prepared for sex without having to plan. An event-driven regimen was acceptable to men who occasionally used recreational drugs in the context of sex. For this group, sex usually occurred was generally prearranged. Patterns of sex and recreational drug use figured largely into participants' framings of how they would use PrEP. These behaviors will likely play a role in the uptake of and adherence to PrEP among this population.

Adolescents are disproportionately impacted by HIV in the United States. Optimal effects from antiretroviral therapy (ART) can be achieved through stringent adherence to a daily medication regimen; for adolescents, this may be interrupted due to complex barriers unique to this age group. We previously conducted formative qualitative interviews with HIV-infected adolescents to identify key barriers facing adolescents regarding ART adherence and potential strategies to address these barriers. These data were used to inform an ART adherence intervention designed to overcome difficulties unique to HIV-infected adolescents (e.g., internalized stigma and HIV-related shame, disclosure to sexual partners, social life, and extracurricular activities at school, etc.). The resulting intervention—“Positive Strategies To Enhance Problem-solving Skills (Positive STEPS)”—combines five individual counseling sessions with daily text message reminders. We conducted a pilot randomized controlled trial of the intervention against a standard of care control and report on the feasibility of procedures and participant acceptability of the intervention in terms of content, structure, and format. ART adherence was measured in both arms through Medication Event Monitoring System pill caps and self-report. Feasibility and acceptability of the Positive STEPS intervention was evidenced by 90% retention for the intervention sessions; 100% completion of the four-month assessment; and positive responses on postintervention evaluation forms (all intervention participants rated Positive STEPS as “acceptable” or “very acceptable”) and brief exit interviews. At the 4-month assessment visit, the change in ART adherence among the intervention group [mean change score = 13%, standard deviation (SD) = 29.5] was significantly higher compared with the standard of care group (mean change score = −26%, SD = 26.0; Cohen's d effect size = 1.43, confidence interval = 0.17–2.49, p = 0.02). Future testing of the intervention in a fully powered randomized controlled trial to determine efficacy is warranted.

Men who have sex with men (MSM) of color are disproportionately affected by HIV in the United States. Pre-exposure prophylaxis (PrEP) using antiretroviral medications is a newer biomedical prevention modality with established efficacy for reducing the risk of acquiring HIV. We conducted formative qualitative research to explore audience reactions and receptivity to message concepts on PrEP as part of the development of prevention messages to promote PrEP awareness among black and Latino MSM in the United States. In 2013, 48 black and 42 Latino (total study sample = 90) mixed HIV serostatus MSM from Chicago, Ft. Lauderdale, and Kansas City participated in either an individual interview or focus group discussion. Men were recruited online and at community-based organizations in each city. We elicited feedback on the comprehensibility, credibility, and relevance of two draft messages on PrEP. The messages included efficacy estimates from iPrEx, a phase III clinical trial to ascertain whether the antiretroviral medication tenofovir/emtricitabine disoproxil fumarate (commercially known as Truvada

In this commentary, we take the recent introduction of methadone treatment in response to emerging problems of HIV linked to heroin addiction in Kenya as a case for reflecting on the social science of implementation science. We offer a framework of 'evidence-making intervention' which we hold as distinct from mainstream 'evidence-based intervention' approaches. Whilst accepting that interventions are shaped in their contexts, evidence-based intervention approaches tend to imagine a stable intervention object with universal effect potential. By contrast, an evidence-making intervention approach investigates how an intervention, and the knowledge which constitutes it, is made locally, through its processes of implementation. Drawing on qualitative research generated in Kenya prior to (2012-2013) and during (2014-2015) the implementation of methadone treatment, we explore the making of 'methadone promise' as a case of evidence-making intervention. We show how enactments of methadone promise make multiple methadones, through which a binary is negotiated between the narratives of methadone as hope for addiction recovery and methadone as hope for HIV prevention. Addiction recovery narratives predominate, despite methadone's incorporation into policy via its globally supported HIV prevention evidence-base. Key practices in the making of methadone promise in Kenya include its medicalization, and renaming, as 'medically assisted treatment' - or simply 'MAT' - which distance it from prior constitutions elsewhere as a drug of substitution, and the visualisation of its effects wherein unhealthy people can be seen and shown to have become well. We also show how actors seek to protect the story of methadone promise from counter narratives, including through mass media projects. We conclude that there is no single biomedical object of methadone intervening on a single biological body across contexts, and no single universe of evidence. By giving weight to local rather than outside expert knowledge, and by tracing how the meaning of intervention is made locally through its implementation, we can make visible the multiple enactments of an intervention and how these shape local ecologies of care, including in ways beyond those foreseen by an intervention's evidencing elsewhere.

An emerging HIV epidemic can be seen among men who have sex with men (MSM) in Vietnam. There are currently no evidence-based behavioral sexual risk reduction interventions for MSM in this setting. Between October 2012 and June 2013, 100 high-risk MSM from Ho Chi Minh City were enrolled in an open pilot trial to assess feasibility and acceptability of a group-based, manualized sexual risk reduction intervention, and to preliminarily examine changes in primary and secondary outcomes. Participants completed a behavioral assessment battery and HIV testing at baseline, 3, and 6 months post-baseline. Over 80.0 % of the sample was

Men who have sex with men (MSM) are at increased risk for HIV infection in India, particularly those who engage in transactional sex with other men (i.e., male sex workers; MSW). Despite the need, HIV prevention efforts for Indian MSW are lacking. As in other settings, MSW in India increasingly rely on the use of mobile phones for sex work solicitation. Integrating mobile phone technology into an HIV prevention intervention for Indian MSW may mitigate some of the challenges associated with face-to face approaches, such as implementation, lack of anonymity, and time consumption, while at the same time proving to be both feasible and useful. This is a pilot randomized controlled trial to examine participant acceptability, feasibility of study procedures, and preliminary efficacy for reducing sexual risk for HIV. MSW (N = 100) were equally randomized to: (1) a behavioral HIV prevention intervention integrating in-person and mobile phone delivered HIV risk reduction counseling, and daily, personalized text or voice messages as motivating "cognitive restructuring" cues for reducing condomless anal sex (CAS); or (2) a standard of care (SOC) comparison condition. Both groups received HIV counseling and testing at baseline and 6-months, and completed ACASI-based, behavioral and psychosocial assessments at baseline, 3, and 6 months. Mixed-effects regression procedures specifying a Poisson distribution and log link with a random intercept and slope for month of follow-up was estimated to assess the intervention effect on the primary outcomes: (1) CAS acts with male clients who paid them for sex, and (2) CAS acts with male non-paying sexual partners-both outcomes assessed over the past month. The intervention was both feasible (98% retention at 6-months) and acceptable (>96% of all intervention sessions attended); all intervention participants rated the intervention as "acceptable" or "very acceptable." A reduction in the reported number of CAS acts with male clients who paid them for sex in the past month was seen in both study conditions. MSW in the intervention condition reported a faster rate of decline in the number of CAS acts with male clients in the past month from the baseline to both the 3-month (B = -1.20; 95% CI -1.68, -0.73; p

Pre-exposure prophylaxis (PrEP) is efficacious for HIV prevention when taken consistently; however, barriers to PrEP use are poorly understood among individuals who could benefit from PrEP, including men who have sex with men (MSM) who engage in transactional sex (i.e., sex exchanged for money or drugs). Two hundred and thirty-seven HIV-uninfected, PrEP-naive MSM reporting concurrent substance dependence and sexual risk completed a questionnaire on PrEP use barriers. Barriers to PrEP use for MSM who engaged in recent transactional sex (22 %) versus those who had not were compared using an ecological framework. Individual (e.g., HIV stigma, substance use) and structural (e.g., economic, healthcare) barriers did not differ (p > 0.05). MSM who recently engaged in transactional sex were more likely to report that anticipated stigma from primary and casual partners would be barriers to PrEP use. Assessing recent transactional sex may help identify men who may need additional counseling to avoid anticipated stigma so they can integrate PrEP into their lives.

Men who have sex with men (MSM) in India are a hidden and largely understudied population, and have an HIV prevalence 17 times higher than that of the general Indian population. Experiences of social marginalization and negative psychosocial conditions occur concurrent to HIV risk among Indian MSM. To better understand the contextual variables driving HIV risk and inform intervention development, five focus groups (n = 46) and nine key informant interviews were conducted with 55 MSM in Chennai in 2010. NVivo software was used to code the transcripts, and data were analyzed using qualitative descriptive analysis methodology. Participants described sources of psychological distress and low self-worth related to gender non-conformity and sexual minority status. These included stigma from society, pressure to marry, lack of familial acceptance, childhood sexual abuse, and the imperative to keep sexual minority status a secret. Participants' personal evaluations revealed that self-acceptance may be an important resilience factor that can shield these psychosocial and HIV risk factors. In promoting health-seeking behavioral changes for Indian MSM at an individual level, our findings point to the potential strength of strategies that focus on self-acceptance of one's sexual minority identity to foster better psychosocial and overall health.

Young adults in South Africa are at the epicenter of the HIV epidemic. The prevalence of HIV among young people in the province of KwaZulu-Natal (KZN) is particularly high. This study characterizes inkwari (Zulu word for raves or weekend-long parties) in eThekwini District, KZN and explored how these place-based dynamics shape the risk environment for the young adult attendees. In 2011, 13 qualitative interviews were conducted with men and women between 18 and 30 years-old who reported unprotected sex with at least one casual partner in the prior 3 months and attended an inkwari in the same time period. Interviews were analyzed using qualitative content analysis. Nine key informant interviews helped to triangulate these data. Five women and eight men were interviewed and the mean age was 25 years (SD 3.24). Ten reported meeting a sexual partner at an inkwari. Inkwari were characterized as sexualized settings with limited adult supervision. Participants attended inkwari to socialize with peers, use drugs and alcohol, and meet sexual partners. Sexual and physical violence also occurred at inkwari. Given the convergence of social, sexual, and substance- using networks at inkwari, further inquiry is needed to determine how this place may potentiate HIV transmission risk in an endemic setting.

In Vietnam, the co-occurrence (i.e., “syndemic”) of psychosocial factors (e.g., depression and substance use) may disproportionately burden male sex workers and increase their HIV risk. A comprehensive survey was conducted among 300 male sex workers in Ho Chi Minh City, Vietnam in 2010. We performed logistic regression to examine the association between the syndemic variable – a count score of the number of 5 psychosocial conditions endorsed – and unprotected anal sex (UAS) in the past. One-third of participants reported any UAS, and 42% reported ≥ 2 psychosocial health problems. In multivariable models, experiencing ≥ 4 psychosocial health problems was significantly associated with UAS. Every unit increase in number of psychosocial health problems was associated with a 25%–30% increase in odds of UAS. Understanding the syndemic condition and its association with HIV risk among male sex workers in Vietnam may lead to the development of more effective, comprehensive interventions.

Innovative techniques, potentially using technology, to improve adherence to antiretroviral therapy (ART), may help patients with HIV who struggle with self-care. This qualitative study compared patient and provider participants’ perspectives on ART adherence and text messaging as a tool to promote adherence. Thirteen providers and 14 HIV-infected patients identified four main themes: 1). facilitators and 2). barriers to using text message reminders as a medium for ART medication reminders; 3). framing of text message reminders; and 4). patient responsibility and autonomy in management of their health and wellness. Ease of use, access, convenience, and confidentiality were cited as benefits of a text message based adherence intervention; while access, cost, difficulty manipulating cellular phones, lack of knowledge/education, and confidentiality were cited as potential barriers. Providers, but not patients, also identified patient apathy and time burden as potential barriers to a text message based adherence reminder system. Patients and providers felt that personalization of messages, attention to timing, and confidentiality of messages were key factors for a successful text message based adherence reminder system. Both providers and patients felt that patient responsibility and autonomy over an individual’s own health care is an important issue in adherence to medical care. The majority of patients and providers felt that a text message based adherence reminder system would be beneficial. While patients and providers had many similar views on factors influencing adherence with ART and the use of text messaging to improve adherence, there were some divergent views between the two groups.

An emerging HIV epidemic can be seen among men who have sex with men (MSM) in Vietnam, with prevalence as high as 18%. Transactional sex represents a risk factor for HIV transmission/acquisition among MSM globally, particularly in urban contexts, but remains largely underinvestigated in Ho Chi Minh City (HCMC), Vietnam. In 2010, 23 MSM who reported exchanging sex for money in the last month completed a brief survey and semistructured qualitative interview at The Life Centre, a non-governmental organization in HCMC, to assess sociodemographics, individual- and structural-level HIV risk factors and explore acceptable future prevention interventions. Participants' mean age was 24 years. Equal proportions of respondents self-identified as heterosexual/straight, homosexual/gay, and bisexual. Participants had a mean of 158 male clients in the past year, with a median of 60 male clients in the past year (interquartile range [IQR]=70) and reported inconsistent condom use and inaccurate perceptions of HIV risk. Nearly half of the sample reported engaging in unprotected anal sex with a male partner in the past 12 months and one-third with a male client. Major themes that emerged for HIV prevention interventions with male sex workers were those that: (1) focused on individual factors (drug and alcohol use, barriers to condom use, knowledge of asymptomatic STIs, enhancement of behavioral risk-reduction skills, and addressing concomitant mental health issues); (2) incorporated interpersonal and relational contexts (led by peer educators, built interpersonal skills, attended to partner type and intimacy dynamics); and (3) considered the exogenous environments in which individual choices/relationships operate (stigma of being MSM in Vietnam, availability of alternative economic opportunities, and varied sexual venues). HIV prevention efforts are needed that address the specific needs of MSM who engage in transactional sex in HCMC. Universally, MSM endorsed HIV prevention interventions, suggesting a need and desire for efforts in this context.

Male sex workers (MSW) are a significant but invisible population in India who are at risk for HIV/STI. Few studies from India have documented HIV risk factors and motivations for sex work in this population. Between 2013 and 2014, a community-based convenience sample of 100 MSW in Chennai (south India) completed a baseline risk assessment as part of a behavioral intervention. Participants were ≥18 years, and reported current sex work. We report medians and proportions, and Wilcoxon-Mann-Whitney and chi-square tests are used to examine differences between sex work and sexual behavior measures by income source. Participants were engaged in sex work for 5.0 years (IQR=2.3-10.0), and earned 3,000 (IQR=2000-8000) Rupees (

In India men who have sex with men and engage in sex work (i.e., male sex workers; MSW) have a high risk of transmitting HIV. Globally, sex workers have become more spatially mobile due to advances in mobile-phone technology. In 2012 in-depth qualitative feedback was garnered from 40 interviews with MSW and four focus groups with 35 key informants (KIs) who had expert knowledge of the local MSW community to inform the design of an HIV-prevention intervention among MSW in Chennai, India. All MSW were recruited during outreach by employees of a Chennai-based organization for MSM (men who have sex with men). The data were analyzed using a descriptive qualitative approach. MSW and KIs discussed the need for intervention content that went beyond basic HIV psychoeducation. They emphasized the importance of addressing psychological distress, alcohol-related risk, and sexual communication skills. Concerns were raised about confidentiality, privacy, and scheduling. Participants endorsed a combination of in-person and mobile-phone-delivered sessions as well as the integration of mobile-phone messaging. These findings served as the basis for the development of a theoretically driven, manual-based intervention incorporating mobile phones. An open pilot assessed the feasibility and acceptability of the intervention with eight MSW. Assessments and HIV testing were administered at baseline, 3, and 6 months post-baseline. Exit interviews were conducted at the conclusion of the intervention. Retention for session attendance and assessment follow-up was 100 %. There was a high level of acceptability for the format, structure, and content. These data show initial promise, feasibility, and acceptability of the intervention.

We examined data derived from a needs assessment of the personal and social characteristics and HIV risk behavior of street-based male sex workers, in Providence, Rhode Island, who engage in transactional sexual intercourse with other men. Substance use, injected drugs, needle sharing, and psychosocial distress were highly prevalent among the sample. History of physical, sexual, and emotional abuse was associated with increased risk of condomless anal sexual intercourse with paying male clients.

There is little data on the burden of HIV and other infections that affect male sex workers (MSW) in Vietnam. We conducted behavioral and biological sexual health surveys with 300 MSW in Ho Chi Minh City. Generalized estimating equation models were built to assess factors associated with HIV, hepatitis C, and other sexually transmitted infections (STI). Of 300 MSW, 19 (6.3 %) were diagnosed seropositive for HIV, 11 (3.7 %) had hepatitis C, and 26 (8.7 %) had at least one prevalent STI. In a multivariable model, opiate use was significantly associated with HIV infection (aOR 6.46, 95 % CI 1.28-32.7) and hepatitis C (aOR = 19.6, 95 % CI 2.35-163.6). Alcohol dependency was associated with increased odds of hepatitis C (aOR = 4.79, 95 % CI 1.02-22.5) and decreased odds of other STI (aOR = 0.30, 95 % CI 0.10-0.97). These findings suggest that MSW in Vietnam would benefit from regular HIV and STI testing, as well as linkage to care and substance use rehabilitation services.

Alcohol and stimulant use are independently associated with increased HIV acquisition among men who have sex with men (MSM). We assessed differences in acceptability and perceived barriers to uptake of pre-exposure prophylaxis (PrEP) among stimulant and alcohol-using MSM in Boston. From September 2012–2013, a quantitative assessment was conducted with 254 MSM respondents who reported recent condomless sex in the context of concurrent stimulant (crack/cocaine and crystal methamphetamine; n = 132) or alcohol use (n = 122). Thirteen (5.1 %) reported previous PrEP use. In multivariable models, stimulant users were more likely to be concerned that substance use would affect PrEP adherence (aRR = 2.79, 95 % CI 1.63–4.77), and were less concerned about HIV stigma as a barrier to PrEP uptake (aRR = 0.52, 95 % CI 0.30–0.90) compared to alcohol users. Barriers to PrEP uptake and adherence differ by type of substance used. Different strategies may be required for PrEP implementation among MSM who use stimulants and alcohol.

In Vietnam, there is an emerging HIV epidemic among men who have sex with men (MSM). Male sex workers (MSWs) engage in high-risk sexual behaviours that make them particularly vulnerable to HIV infection. In 2010, 23 MSM in Ho Chi Minh City (HCMC) who recently received payment for sex with another man completed in-depth qualitative interviews exploring motivations for sex work, patterns of sex work disclosure and experiences of social stigma. Interviews were recorded, transcribed and translated into English and analysed using a qualitative descriptive approach. Low wages, unstable employment, and family remittances were motivating factors for MSM in HCMC to sell sex. Participants described experiences of enacted and felt social stigma related to their involvement in sex work. In response, they utilized stigma management techniques aimed at concealment of involvement in sex work. Such strategies restricted sexual communication with non-paying sex partners and potentially limited their ability to seek social support from family and friends. Departing from decontextualized depictions of sex work disclosure, our findings describe how decisions to reveal involvement in sex work are shaped by social and structural factors such as social stigma, techniques to minimize exposure to stigma, economic imperatives and familial responsibilities.

The success of global treatment as prevention (TasP) efforts for individuals living with HIV/AIDS (PLWHA) is dependent on successful implementation, and therefore the appropriate contribution of social and behavioral science to these efforts. Understanding the psychosocial context of condomless sex among PLWHA could shed light on effective points of intervention. HPTN 063 was an observational mixed-methods study of sexually active, in-care PLWHA in Thailand, Zambia, and Brazil as a foundation for integrating secondary HIV prevention into HIV treatment. From 2010–2012, 80 qualitative interviews were conducted with PLWHA receiving HIV care and reported recent sexual risk. Thirty men who have sex with women (MSW) and 30 women who have sex with men (WSM) participated in equal numbers across the sites. Thailand and Brazil also enrolled 20 biologically-born men who have sex with men (MSM). Part of the interview focused on the impact of HIV on sexual practices and relationships. Interviews were recorded, transcribed, translated into English and examined using qualitative descriptive analysis. The mean age was 25 (SD = 3.2). There were numerous similarities in experiences and attitudes between MSM, MSW and WSM across the three settings. Participants had a high degree of HIV transmission risk awareness and practiced some protective sexual behaviors such as reduced sexual activity, increased use of condoms, and external ejaculation. Themes related to risk behavior can be categorized according to struggles for intimacy and fears of isolation, including: fear of infecting a sex partner, guilt about sex, sexual communication difficulty, HIV-stigma, and worry about sexual partnerships. Emphasizing sexual health, intimacy and protective practices as components of nonjudgmental sex-positive secondary HIV prevention interventions is recommended. For in-care PLWHA, this approach has the potential to support TasP. The overlap of themes across groups and countries indicates that similar intervention content may be effective for a range of settings.

Men who have sex with men (MSM), including male sex workers (MSW), in Vietnam are at high risk for HIV transmission and acquisition, due to specific psychosocial and contextual factors including stigma and discrimination.1,2 MSW are particularly vulnerable due to the local legal environment, power dynamics (i.e., dependence on sex for livelihood), and individual-level risk.3 However, despite increasing HIV prevalence,4 few HIV prevention interventions have been specifically developed for this population. Identification of HIV prevention strategies that are tailored to the needs of MSW are urgently needed. The iPrEx trial demonstrated the efficacy of taking daily oral pre-exposure prophylaxis (PrEP) to reduce HIV transmission among MSM.5 To date, little research has specifically considered the acceptability of PrEP among MSW in Vietnam. PrEP may be a particularly useful intervention for MSW as it is a user-controlled intervention. Peer educators (PE) are valuable sources of HIV prevention information for MSW in Vietnam,6 and may have a role to play in the development and administration of PrEP interventions. We assessed factors associated with access to PE and the association between contact with a PE and willingness to take PrEP as a potential strategy for implementation of PrEP interventions. In 2010, a behavioral and psychosocial survey was undertaken with 300 MSW in Ho Chi Minh City (HCMC), Vietnam, which assessed past experience with HIV prevention activities and interest in PrEP. The survey was developed following an initial qualitative phase.6 Detailed methods have been described previously.7 Briefly, participants were recruited by PE from a Vietnamese NGO working with MSM, using venue-based sampling stratified on where participants met clients (i.e., street, brothel). Eligible participants were at least 15 years of age, biologically male, Vietnamese citizens who reported exchanging sex for money or goods at least once in the previous month. The survey was anonymous, and participants gave verbal informed consent after receiving information about the study from one of the research staff. Study procedures were approved by the Institutional Review Boards at Beth Israel Deaconess Medical Center and the Ho Chi Minh City Provincial AIDS Committee. The survey contained items pertaining to past participation in HIV prevention programs including if they had received HIV prevention materials (i.e., condoms, personal lubricant, or informational brochures), knowledge of HIV testing and counseling services, HIV/STI testing history, and contact with PE in the previous 12 months. Questions pertaining to willingness to participate in future HIV prevention interventions were adapted from prior studies by our group8 and asked if they would take a daily pill if it would protect against HIV and how likely they were to take the pill if it had side effects. Demographic and behavioral factors were also assessed. Descriptive statistics were calculated for responses regarding past HIV prevention activities and willingness to take PrEP. Logistic regression models were used to analyze the association between demographic and behavioral factors and (1) past contact with a PE; and (2) being at least “somewhat likely” to take a daily pill for HIV prevention if it had side effects. A multivariable model for each outcome was built using backwards elimination starting with all potential covariates, with a p value cutoff of 0.2 to determine the final variables to retain in the model. An alpha level of 0.05 was considered significant. Stata 12.0 (StataCorp, College Station, TX) was used for all analyses. Of 300 participants in the original study, 281 (93.7%) were HIV-uninfected and included in these analyses.9 Table 1 lists the proportion of participants who indicated previous participation in HIV prevention activities and interest in PrEP. More than 2/3 of participants had previous contact with a PE. Most (95.4%) participants indicated that they would take PrEP, although substantially fewer indicated they would take PrEP given side effects (56.7%). Table 1. Proportion of Participants Who Have Participated or Would Participate in HIV Prevention Interventions (N=281) Table 2 displays bivariate and multivariable models assessing factors associated with (1) contact with a PE in the previous year, and (2) being at least “somewhat likely” to take PrEP if it had side effects. MSW who reported previous contact with a PE (AOR 2.28, 95% CI 1.25–4.14) indicated increased willingness to use PrEP. In a multivariable model, older age (AOR 1.09, 95% CI 1.01–1.16) was associated with increased contacts with PE, and identifying as bong lâ (effeminate, AOR 0.29, 95% CI 0.11–0.75), or trai thang (“straight boy”, AOR 0.43, 95% CI 0.23–0.80) versus bong kin (masculine) was associated with decreased contact with PE. Table 2. Bivariate and Multivariable Logistic Regression Models Assessing Factors Associated with Contact with Peer Educator in Last 12 Months and Willingness to Take Pre-Exposure Prophylaxis (PrEP) If It Involved Side Effects Participants who had previous contact with a PE more frequently indicated that they would take PrEP than those who had not. As PrEP becomes available for MSM in Vietnam, PE will likely play a large role in recruiting and educating participants about the efficacy of PrEP, adherence, and safer sex practices, and counseling related to stigma, side effects, and local resources. Training PE may increase the acceptability of PrEP for Vietnamese MSM, and their role in the expansion of PrEP services in Vietnam should be carefully considered. Given the high penetrance of PE in this population, leveraging this existing infrastructure may improve the feasibility and success of future HIV prevention interventions such as PrEP. Strategies to increase access to PE among key subpopulations are important to improve the scope and quality of programs based on this model. In this study, older men were more likely to have been reached by PE in the past year. This could reflect differences in social networks,10 and they are likely to have had more opportunities to be reached by peers, compared to younger men who have recently “come out.” Younger participants are a particularly vulnerable group, and future work should consider how to engage them in HIV prevention services.11 Participants identifying as bong lộ or trai thang versus bong kin less frequently indicated engagement with PE. While bong lộ are more visible than other MSM identities in Vietnam,12 due to this visibility, they may also be more susceptible to stigma and therefore less likely to be willing to engage in peer education services in public settings. Similarly, trai thang may not want to be seen in public or be less willing to engage in peer education since they identify as “straight”.12 Investments should be made to identify strategies to facilitate engagement with PE by bong lộ or trai thang. This study has several potential limitations. Data collection relied on self-report, which could result in under- or over-reporting of sensitive behaviors. Questionnaires were administered by interviewers, which could result in social desirability bias. Finally, questions regarding side effects related to PrEP did not specify the specific side effects may be, or how severe they could be. More in-depth questions could elucidate which side effects would be barriers to taking PrEP among this population. PE may have the ability to access vulnerable hidden populations that are not reached by mainstream HIV prevention messages, which could maximize uptake of interventions such as PrEP. The results of this study indicate that integrating PE into future PrEP interventions may be an effective way to engage MSW in PrEP. The development of interventions that reach MSW and ensuring they are aware of choices and strategies for HIV prevention will be an important component of a comprehensive HIV prevention strategy in for MSW in Vietnam.

Whoonga is a drug cocktail in South Africa rumored to contain illicit drugs and HIV antiretroviral (ARV) medication. Although its use may adversely impact adherence to HIV treatment and may have the potential to generate ARV resistance, there is a paucity of research characterizing whoonga. We learned of whoonga during semi-structured interviews about substance abuse and HIV risk at “club-events” known as inkwaris in an urban township of Durban, South Africa. Whoonga was an emerging theme spontaneously identified as a problem for the community by 17 out of 22 informants. Perceptions of whoonga suggest that it is highly addictive, contains ARVs (notably efavirenz), is used by individuals as young as 14, and poses a threat to the health and safety of those who use it, including increasing the risk of HIV infection. Our informants provide preliminary evidence of the dangers of whoonga and reinforce the need for further study.

Men who have sex with men (MSM) remain at great risk of HIV in the United States, representing 65 % of incident HIV infections. One factor contributing to the high rate of HIV infection among MSM is use of “recreational” drugs that are highly associated with unprotected anal sex. Pre-exposure chemoprophylaxis (PrEP) is a novel biomedical HIV prevention strategy that has the potential to reduce HIV transmission in MSM. Main and casual sex partners play a role in HIV prevention efforts for MSM. The study aimed to qualitatively explore the perceived influences of sexual relationships on promoting and inhibiting PrEP use among high-risk MSM who report regular drug use. Semi-structured qualitative interviews were conducted with 40 participants recruited in Boston, Massachusetts. Data were analyzed using descriptive qualitative analysis. Casual partners presented a distinct set of concerns from primary partnerships. MSM generally viewed main partners as a potential source of support for taking PrEP. Given their informal and often temporary nature, PrEP disclosure to casual partners was considered unnecessary. HIV-related stigma and substance use were also perceived as barriers to discussing PrEP use with casual partners. MSM articulated a high degree of personal agency regarding their ability to take PrEP. Findings suggest that behavioral interventions to improve PrEP utilization and adherence for high-risk MSM should be tailored to sex partner type and the parameters established between sex partners. Approaches to PrEP disclosure and partner engagement should be informed by the relative benefits and limitations characterized by these different types of relationships.

Male sex workers (MSW) in Vietnam face high levels of stigma related to sex work, which may be associated with depression and increased vulnerability to HIV. In 2010, 300 MSW completed a behavioral and psychosocial survey. Multivariable models assessed factors associated with sex work-related stigma and the association between stigma and depression. Factors associated with increased stigma included having disclosed sexual orientation to healthcare workers (b 1.75, 95 % CI 0.69–2.80), meeting clients in the street/park (b 1.42, 95 % CI 0.32–2.52), and having been forced to have sex without a condom (b 2.36, 95 % CI 1.27–3.45). Factors associated with decreased stigma included meeting clients via the telephone or internet (b −1.26, 95 % CI −2.39 to −0.12) and receiving financial support from family or friends (b −1.31, 95 % CI −2.46 to −0.17). Stigma was significantly associated with increased odds of depression (AOR 1.07, 95 % CI 1.01–1.15). Addressing stigma and depression in HIV prevention interventions is crucial for tailoring these programs to MSWs’ needs, and may result in decreased HIV spread.

The international community has overcome many obstacles in making HIV antiretroviral (ARV) medication available globally, but ARV resistance in treatment-naive individuals remains an implementation challenge. The subject of many recent reports,1-3 worries abound that pretreatment ARV resistance is related to treatment failure and that further increases in the rates of pretreatment ARV resistance might “jeopardise the global HIV response”.1,2 Largely attributed to transmitted resistance, pretreatment ARV exposure such as inadequate treatment outside of sanctioned care networks is believed to be a contributing factor.3 While investigating HIV-risk behaviour in South Africa,4 we learned of a preventable form of pretreatment ARV exposure that has gone largely unreported and may accelerate rates of pretreatment ARV resistance: the recreational use of ARVs referred to by our informants as “whoonga”. Whereas whoonga has received significant media attention since 2010, the first and only report in the medical literature documenting the recreational use of ARVs appeared years earlier from the United States. In discussions with HIV-infected individuals in Miami about prescription drug diversion, Inciardi and colleagues learned that some individuals abuse efavirenz for its “intoxicating” effects and use ritonavir to enhance the effects of illicit drugs such as methamphetamine and 3,4-methylenedioxymethamphetamine (MDMA/ecstasy).5 Claims about the psychoactive effects of these ARVs are supported by scientific case reports.6,7 Similar ARV abuse patterns in South Africa have been reported in the social science literature and news media. Larkan and colleagues provide an account of individuals smoking efavirenz in Western Cape and summarise media reports that ARVs are combined with illicit drugs such as opiates, methamphetamine, and/or marijuana to make drug cocktails.8 Whoonga, believed to be one such cocktail, brought media attention to the problem of recreational ARV use in Kwazulu-Natal because of its addictive potential, its association with criminal activity, and the challenge it posed to ARV rollout.9 Even local experts who maintain that whoonga is heroin and does not contain ARVs acknowledge that a number of South African drug abusers use ARVs recreationally.10 Although essentially a substance abuse problem, the implications for HIV treatment are broad. For example, diversion of ARVs, in addition to impacting adherence, reduces ARV supply and limits access to treatment. Criminal behaviour related to diversion of ARVs endangers patients and healthcare providers while deterring others from seeking care. Finally, the recreational use of ARVs further stigmatises HIV-infected patients and their communities and may undermine donor willingness to fund ARV treatment.8 In addition to these impacts, when untreated HIV-infected individuals are exposed to ARVs recreationally, they are at risk for acquiring resistance.8 Mutations conferring resistance to non-nucleoside reverse transcriptase inhibitors (NNRTIs) such as efavirenz are among the most common in individuals with pretreatment ARV resistance.1-3 Interestingly, serum concentrations of ARVs including efavirenz have been detected in some HIV-infected individuals with pretreatment ARV resistance who deny prior history of ARV treatment.3 To help explain some of these findings, researchers may wish to inquire specifically about recreational ARV use or use of drug cocktails when assessing pretreatment ARV exposure. Expanding pretreatment ARV resistance screening will help to minimize the risk that this form of pretreatment ARV exposure poses; however, a comprehensive strategy to investigate this problem also involves expanding substance abuse research. Existing substance abuse surveillance methods have not reported on the phenomenon,11,12 and they may need to be improved if we are to understand the extent of pretreatment ARV exposure from recreational ARV use. Systematic research is also needed to explore the chemical makeup of South African street drugs, the abuse liability of ARVs, and the bioavailability and likelihood of developing resistance when ARVs are smoked or otherwise administered inappropriately. Given the high prevalence and complex medical, psychosocial, and political context of HIV in southern Africa, it is important that treatment strategies adapt to emerging issues like recreational ARV use. We may decrease the recreational use of ARVs, decrease drug diversion, and improve adherence to HIV treatment if we avoid ARVs used recreationally when developing ARV treatment guidelines or distribute ARVs to patients in a way that minimizes the potential for misuse. The recreational use of ARVs also serves as a reminder that ARV treatment is not synonymous with HIV treatment and demonstrates the importance of access to effective community-based mental health and substance abuse services.

Men who have sex with men (MSM) in India have an HIV seroprevalence 22 times greater than the country's general population and face unique challenges that may hinder the effectiveness of current HIV prevention efforts. To obtain an understanding of the logistical and sociocultural barriers MSM experience while accessing HIV prevention services, focus groups and key informant interviews were conducted with 55 MSM in Chennai, India. Qualitative data were analyzed using descriptive qualitative content analysis. Sixty-five percent of participants identified as kothi (receptive partners), 9% as panthi (insertive partners), 22% as double decker (receptive and insertive), and 4% did not disclose. Themes included: (a) fatigue with current HIV risk reduction messages; (b) increased need for non-judgmental and confidential services; and (c) inclusion of content that acknowledges individual and structural-level determinants of risk such as low self-esteem, depression, and social discrimination. MSM interventions may benefit from approaches that address multilevel psychosocial factors, including skills building and strategies to foster self-acceptance and increased social support.
