Knowledge and willingness to use pre-exposure prophylaxis among men who have sex with men in Northeastern Brazil

Few studies evaluate knowledge and willingness to use pre-exposure prophylaxis (PrEP) among men who have sex with men (MSM) in middle-income countries. Brazil added PrEP to public drug formularies in December 2017, but little is known about local knowledge and attitudes about PrEP among MSM outside metropolitan areas in Southern Brazil. The cross-sectional HIV Surveillance Survey Project in Brazil estimates HIV and STD prevalence among MSM in 12 state capitals. Among 32 participants at the Salvador, Bahia study site, we used qualitative interviews to assess knowledge, willingness, and barriers to PrEP use among MSM; few MSM had previous knowledge of PrEP and were willing to use PrEP. Clinical, behavioural, social, and structural factors influencing participants’ knowledge and willingness to take PrEP included concerns about efficacy and side effects, access to culturally congruent services for MSM, and stigma. Some participants reported that learning about PrEP online positively influenced their willingness to use PrEP. Participants’ opinions about PrEP’s contribution to risk compensation varied. Interventions to provide culturally congruent care and destigmatise PrEP for MSM at high risk for HIV acquisition, particularly those conducted collaboratively with Brazil’s civil society movement, may enhance the public health effort to expand access to PrEP in Brazil.     

Modeling the Impact of PrEP Programs for Adolescent Sexual Minority Males Based on Empirical Estimates for the PrEP Continuum of Care

PurposePre-exposure prophylaxis (PrEP)—an effective and safe intervention to prevent HIV transmission—was recently approved by the Food and Drug Administration for use by adolescents. Informed by studies of sexual behavior and PrEP adherence, retention, and promotion, we model the potential impact of PrEP use among at-risk adolescent sexual minority males.MethodsWe simulate an HIV epidemic among men who have sex with men (MSM) aged 13–39. We assume adult MSM ages 19–39 have had PrEP available for 3 years with 20% coverage among eligible MSM based on the Centers for Disease Control and Prevention guidelines. PrEP interventions for ages 16–18 are then simulated using adherence and retention profiles drawn from the ATN113 and Enhancing Preexposure Prophylaxis in Community studies across a range of uptake parameters (10%–100%). Partnerships across age groups were modeled using parameterizations from the RADAR study. We compare the percent of incident infections averted (impact), person-years on PrEP per infection averted (efficiency), and changes in prevalence over 10 years.ResultsAs compared to no PrEP use, baseline PrEP adherence and retention among adolescent sexual minority males drawn from the ATN113 and Enhancing Preexposure Prophylaxis in Community studies averted from 2.8% to 41.0% of HIV infections depending on the fraction of eligible adolescent sexual minority males that initiated PrEP at their annual health-care visit. Improved adherence and retention achieved with an array of focused interventions from real-world settings increased the percent of infections averted by as much as 26%–70%.ConclusionsEmpirically demonstrated improvements in the PrEP continuum of care in response to existing interventions can substantially reduce incident HIV infections among adolescent sexual minority males.     

Qualitative investigation of factors impacting pre‐exposure prophylaxis initiation and adherence in sexual minority men

IntroductionMen who have sex with men continue to account for the majority of new HIV infections in the United States. Many of those with new infections are unaware that they have HIV. Preventative measures continue to be essential in reducing new infections, with pre‐exposure prophylaxis (PrEP) being widely recommended.ObjectivesThe overall aim of this qualitative study is to explore the impact of stigma, patient–provider dynamics and patient perception of PrEP on men''s engagement with PrEP in a primary care setting.MethodsThe Consensual Qualitative Research Methodology (Hill, 2012) was used to explore the experiences of 14 men receiving care for PrEP at a Family Medicine clinic in the Midwest. Semistructured interviews were conducted to allow for depth of understanding of individuals'' experience.ResultsFour major domains were identified: motivation to pursue PrEP, barriers and adherence to care, beliefs about how PrEP is perceived by others and experiences discussing sexual health and PrEP with providers.ConclusionIt is important to better understand factors contributing to the pursuit of and adherence to HIV prevention measures and HIV care. Further, health systems and providers are encouraged to consider opportunities in terms of how their practice can destigmatize PrEP use and offer a welcoming environment for those pursuing HIV prevention.Patient or Public ContributionPatients were involved in the study through their participation in semistructured interviews, which provided the data analysed for this study. There was no additional participation beyond the one‐time interview or follow‐up poststudy. Their interviews helped contribute to our better understanding of the needs and experiences of those receiving PrEP‐related care.     

A Human Rights Case Study on Access to Pre-exposure Prophylaxis for Female Sex Workers in South Africa

This paper examines the extent to which access to HIV preventive medicines such as pre-exposure prophylaxis (PrEP) are ensured under the International Covenant on Economic, Social and Cultural Rights. There is a lack of human rights-focused research on access to HIV preventive medicines for vulnerable populations such as female sex workers in HIV-endemic countries. To help fill this gap, I utilized a case study approach to critically examine the rollout of PrEP for female sex workers in South Africa, drawing on the country’s Bill of Rights, health care policies, and PrEP implementation. My analysis found that (1) PrEP rollout was largely physically and economically inaccessible for female sex workers outside of urban centers; (2) the dissemination of PrEP information specific to female sex workers was limited both virtually and in clinics, reducing the medicine’s acceptability; and (3) South Africa’s overburdened public health care system and continued criminalization of sex work limited the accessibility and quality of HIV prevention services, contributing to weak uptake of PrEP among female sex workers. To remedy these issues, state leaders should prioritize PrEP counseling and socially acceptable information dissemination; expand comprehensive, coherent, and coordinated sexual health services for female sex workers; increase the financial resources available for programs specific to female sex workers; and decriminalize sex work.     

Connecting the Dots: Examining Transgender Women’s Utilization of Transition-Related Medical Care and Associations with Mental Health,Substance Use,and HIV

Findings on access to general healthcare for transgender people have emerged, but little is known about access to transition-related medical care for transwomen (i.e., hormones, breast augmentation, and genital surgery). Transgender women have low access to general medical care and are disproportionately at risk for substance use, mental illness, and HIV. We conducted an analysis to determine if utilization of transition-related medical care is a protective factor for health risks to transgender women and to investigate if care differs by important demographic factors and HIV status. A secondary analysis was conducted using data from a 2010 HIV surveillance study using respondent-driven sampling to recruit 314 transwomen in San Francisco. Survey-corrected logistic regression models were used to estimate odds ratios for six psychosocial health problems—binge drinking, injection drug use, anxiety, depression, suicidal ideation, and high-risk intercourse—comparing various levels of utilization of transition-related medical care. Odds ratios were also calculated to determine if utilization of transition-related medical care was related to less overlap of risk domains. We found that Latina and African American transwomen had significantly lower estimated utilization of breast augmentation and genital surgery, as did transwomen who identified as transgender rather than female. Overall, utilization of transition-related medical care was associated with significantly lower estimated odds of suicidal ideation, binge drinking, and non-injection drug use. Findings suggest that utilization of transition-related medical care may reduce risk for mental health problems, especially suicidal ideation, and substance use among transwomen. Yet, important racial/ethnic and gender identity disparities in utilization of transition-related medical care need to be addressed.     

Parents’ Perspectives About Adolescent Boys’ Involvement in Biomedical HIV Prevention Research

Research on the use of pre-exposure prophylaxis (PrEP) among adolescents at high risk for HIV is urgently needed, and parents’ perspectives on these studies are essential for guiding the responsible conduct of adolescent PrEP research. We conducted interviews with 30 parents of adolescent boys (50% known/presumed heterosexual; 50% sexual minority) to understand their views of research risks and benefits and parental permission regarding their son’s involvement in a hypothetical PrEP adherence trial. Parents identified several health and educational benefits of the study and expressed that waiving parental permission would overcome barriers to accessing PrEP, particularly for youth who may benefit most. Among their concerns were medication non-adherence and risk compensation. Parents provided suggestions to facilitate informed, rational, and voluntary participation decisions and protect youth’s safety if parental permission was waived. These findings can inform ways to increase parental trust in PrEP research and create adequate protections for adolescent participants.     

Knowledge and Attitudes About Pre-Exposure Prophylaxis Among Young Adults Experiencing Homelessness in Seven U.S. Cities

Purpose

Evidence suggests that young adults experiencing homelessness (YEH) are at elevated risk of HIV compared to housed youth. Given the limited research on pre-exposure prophylaxis (PrEP) awareness among YEH, this study examined their PrEP knowledge and attitudes.

Experiences of men who have sex with men when initiating,implementing and persisting with HIV pre‐exposure prophylaxis

IntroductionHIV pre‐exposure prophylaxis (PrEP) involves the use of antiretroviral medication in HIV‐negative individuals considered to be at risk of acquiring HIV. It has been shown to prevent HIV and has been available in Wales since July 2017. Measuring and understanding adherence to PrEP is complex as it relies on the simultaneous understanding of both PrEP use and sexual activity. We aimed to understand the experiences of men who have sex with men (MSM) living in Wales initiating, implementing and persisting with HIV PrEP.MethodsWe conducted semistructured interviews with MSM PrEP users in Wales who participated in a cohort study of PrEP use and sexual behaviour. Following completion of the cohort study, participants were invited to take part in a semistructured interview about their experiences of taking PrEP. We aimed to include both individuals who had persisted with and discontinued PrEP during the study. The interview topic guide was informed by the ABC taxonomy for medication adherence and the theory of planned behaviour. We analysed our data using reflexive thematic analysis.ResultsTwenty‐one participants were interviewed, five having discontinued PrEP during the cohort study. The developed themes focused on triggers for initiating PrEP, habitual behaviour, drivers for discontinuation and engagement with sexual health services. Stigma surrounding both PrEP and HIV permeated most topics, acting as a driver for initiating PrEP, an opportunity to reduce discrimination against people living with HIV, but also a concern around the perception of PrEP users.ConclusionThis is the first study to investigate PrEP‐taking experiences incorporating established medication adherence taxonomy. We highlight key experiences regarding the initiation, implementation and persistence with PrEP and describe how taking PrEP may promote positive engagement with sexual health services. These findings may be useful for informing PrEP rollout programmes and need to be explored in other key populations.Patient and Public ContributionPrEP users, in addition to PrEP providers and representatives of HIV advocacy and policy, were involved in developing the topic guide for this study.     

‘I am not a man’: Trans-specific barriers and facilitators to PrEP acceptability among transgender women

ABSTRACT

The frequent conflation of transgender (‘trans’) women with ‘men who have sex with men (MSM)’ in HIV prevention obscures trans women's unique gender identities, social and behavioural vulnerabilities, and their disproportionately high rates of HIV infection. Pre-exposure prophylaxis (PrEP) is an efficacious biomedical HIV prevention approach. However, trans women are underrepresented in PrEP research, and are often aggregated with MSM without consideration for their unique positions within sociocultural contexts. This study examined PrEP acceptability among trans women via three focus groups and nine individual interviews (total N?=?30) in San Francisco. While knowledge of PrEP was low, interest was relatively high once participants were informed. Due to past negative healthcare experiences, ability to obtain PrEP from a trans-competent provider was cited as essential to PrEP uptake and adherence. Participants noted that PrEP could address situations in which trans women experience reduced power to negotiate safer sex, including sex work. Trans-specific barriers included lack of trans-inclusive marketing of PrEP, prioritisation of hormone use, and medical mistrust due to transphobia. Findings underscore the importance of disaggregating trans women from MSM in HIV prevention strategies to mitigate disparate risk among this highly vulnerable population.     

Primary Care Physician Attitudes and Intentions Toward the Use of HIV Pre-exposure Prophylaxis in Adolescents in One Metropolitan Region

Purpose

Understanding the attitudes of physicians toward the use of pre-exposure prophylaxis (PrEP) for HIV prevention among youth is critical to improving access to PrEP. We examined PrEP-related attitudes among physicians who provide primary care to 13- to 21-year-old adolescents.

Housing Status and HIV Risk Behaviors Among Transgender Women in Los Angeles

Due to social stigma, lack of social support, and minimal legal employment opportunities, transgender women (transwomen) face elevated rates of unstable housing. This study examined the association between housing status and HIV risk behaviors among 517 transwomen encountered through street outreach. Seven variables (including sociodemographics, HIV status, housing status, and sexual partner type) were used to estimate partial associations during multivariable analyses; housing status was coded trichotomously (housed, marginally housed, and homeless) for these analyses. Results demonstrated that homeless and marginally housed transwomen engaged in significantly higher rates of illicit drug use than housed transwomen; however, marginally housed and housed transwomen engaged in significantly higher rates of illegal hormone injections than homeless transwomen. Rates of sex work were high in the sample as a whole, though sex with an exchange partner was most common among the marginally housed transwomen. Multivariate logistic regression revealed that unstable housing moderated the association between HIV status and engagement in unprotected serodiscordant anal intercourse. The marginally housed transwomen exhibited the greatest risk profile for HIV acquisition or transmission.     

Training health care providers to provide PrEP for HIV serodiscordant couples attending public health facilities in Kenya

ABSTRACT

To catalyse national scale up of PrEP for HIV serodiscordant couples in public health facilities in Kenya, the Partners Scale-Up Project, using a two-day case-based interactive curriculum, trained health care providers working in 24 high volume facilities in central and western Kenya on PrEP service delivery. Using a standardised test with questions about PrEP and antiretroviral-based HIV prevention we assessed gain in knowledge and confidence gain by comparing pre-and post-training test scores. We explored experiences of the training through key informant interviews after clinics started delivering PrEP. Of 716 health care providers trained, 235 (32.9%) were nurses, 144 (20.2%) were clinical officers and 155 (21.7%) were HIV counsellors. There was a significant improvement between the means of pre-test and post-test scores (61.7% (SD 17.4) vs 86.4% (SD 12.7) p?<?0.001). The proportion of those who reported being ‘very comfortable’ providing care to HIV serodiscordant couples increased from 22.8% to 67.3% (p?<?0.001). Key themes that training increasing both knowledge of PrEP and confidence to deliver PrEP to HIV serodiscordant couples emerged from interviews. This short, standardised training resulted in a substantial increase in knowledge of PrEP and in the confidence of the health providers to provide PrEP to HIV serodiscordant couples.

HIV Pre-Exposure Prophylaxis (PrEP) in a Brazilian Clinical Setting: Adherence,Adverse Events,Sexual Behavior,and Sexually Transmitted Infections

Tenofovir/emtricitabine (TDF/FTC) has been used as pre-exposure prophylaxis (PrEP) in preventing HIV infection. PrEP is an effective prevention tool as demonstrated in clinical trials and studies in clinical practice and was incorporated into the Brazilian public health system in December 2017. The present study was a prospective cohort that included 219 PrEP users monitored over a 10 month follow-up period in a capital city in Northeastern Brazil. Data were collected from the PrEP users’ electronic medical records platform made available by the Brazilian Health Ministry. During the observation period, there was good user retention to the prevention program (84%) and there was high adherence to medication (90%). Almost half the users (49%) presented an adverse event, although these were mild and transient, 30 days after starting prophylaxis. There was a significant reduction in creatinine clearance (p?<?.001), from 104.9 to 83.5 mL/min; however, there was no need for drug discontinuation. Throughout the cohort, there was no significant change in the number of sexual partners, but the use of condoms during sexual intercourse decreased (p?<?.001). There was a non-significant increase in the incidence of syphilis (p?=?.08), and there was a 50% decrease in reporting signs and symptoms of sexually transmitted infections. No cases of HIV infection were observed. PrEP proved to be an effective tool in HIV prevention, presenting few complications of adverse events.

     

Readiness for Use of HIV Preexposure Prophylaxis Among Men Who Have Sex With Men in Malawi: Qualitative Focus Group and Interview Study

BackgroundMen who have sex with men (MSM) are a key group for HIV interventions in Malawi considering their high HIV prevalence (17.5% compared to 8.4% among men in the general population). The use of oral preexposure prophylaxis (PrEP) presents a new opportunity for MSM to be protected. We present the findings from a qualitative assessment designed to assess awareness of and willingness and barriers to using PrEP among MSM in Malawi.ObjectiveThe 3 main objectives of this assessment were to determine: (1) awareness of PrEP, (2) factors that influence willingness to use PrEP, and (3) potential barriers to PrEP use and adherence among MSM in order to guide the design and implementation of a PrEP program in Malawi.MethodsAhead of the introduction of PrEP in Malawi, a qualitative study using in-depth interviews (IDIs) and focus group discussions (FGDs) was conducted in October 2018 in Blantyre, Lilongwe, and rural districts of Mzimba North and Mangochi. With support of members of the population, study participants were purposively recruited from 4 MSM-friendly drop-in centers where MSM receive a range of health services to ensure representativeness across sites and age. Participants were asked what they had heard about PrEP, their willingness to use PrEP, their barriers to PrEP use, and their preferences for service delivery. The data were analyzed using a thematic content analysis framework that was predetermined in line with objectives.ResultsA total of 109 MSM were interviewed—13 through IDIs and 96 through FGDs. Most participants were aware of PrEP as a new HIV intervention but had limited knowledge related to its use. However, the majority were willing to use it and were looking forward to having access to it. IDI participants indicated that they will be more willing to take PrEP if the dosing frequency were appropriate and MSM were involved in information giving and distribution of the drug. FGD participants emphasized that places of distribution and characteristics of the service provider are the key factors that will affect use. Knowing the benefits of PrEP emerged as a key theme in both the IDIs and FGDs. Participants highlighted barriers that would hinder them from taking PrEP such as side effects which were cited in IDIs and FGDs. Key factors from FGDs include cost, fear of being outed, drug stockouts, fear of being known as MSMs by wives, and lack of relevant information. FGDs cited stigma from health care workers, forgetfulness, and community associated factors.ConclusionsDespite having inadequate knowledge about PrEP, study participants were largely willing to use PrEP if available. Programs should include an effective information, education, and communication component around their preferences and provide PrEP in MSM-friendly sites.     

Incorporating HIV Pre-Exposure Prophylaxis Care for Patients Seeking Induced Abortion and Pregnancy Loss Management

BackgroundFamily planning clinical encounters are important opportunities for HIV prevention. Our objectives were to 1) estimate the proportion of patients seeking induced abortion and early pregnancy loss management eligible for HIV pre-exposure prophylaxis (PrEP) and 2) compare PrEP eligibility and uptake between patients with unintended and intended pregnancy.MethodsWe conducted a cross-sectional survey and a nested prospective cohort study of patients seeking an induced abortion or early pregnancy loss management. We assessed pregnancy intendedness, PrEP awareness, HIV risk and risk perception, desire for same-day PrEP start, and PrEP continuation at 30 days. We used the χ² and Fisher's exact tests to assess differences between the participants with intended and unintended pregnancy. We had 80% power to detect a 14% difference in PrEP eligibility between the groups.ResultsWe enrolled 250 women. Fifty-six percent (139) had an unintended pregnancy and 44% (110) had an intended pregnancy. PrEP eligibility did not differ significantly between the patients with intended and unintended pregnancy (16% vs. 10%; p = .18). More than one-half (54%, 135/250) were unaware of PrEP before their study visit, and 93% (232/250) considered themselves unlikely to acquire HIV. Of 33 women who were PrEP eligible, 11 accepted same-day start and 1 continued PrEP at 30 days.ConclusionsIntendedness of pregnancy was unrelated to PrEP eligibility in women seeking induced abortion and early pregnancy loss management. Most patients seeking these services are unaware of PrEP. Integrating PrEP into family planning care is likely to increase awareness and uptake of PrEP in women.     

The Association Between Homophily on Illicit Drug Use and PrEP Conversations Among Latino Men Who Have Sex with Men Friends: A Dyadic Network and Spatially Explicit Study

Despite the wide availability of PrEP, Latino men who have sex with men (LMSM) continue to experience access barriers. Novel HIV prevention research strategies to increase PrEP uptake and adherence among the high incidence populations, such as LMSM who misuse drugs, include social network analyses. This study identified the associations of drug use homophily within LMSM friendship networks and PrEP promotion conversations and described the physical overlap between geographic drug risk areas with conversations of PrEP promotion. Respondent-driven sampling was used to recruit 10 sociocentric networks. Quadratic assignment procedure (QAP) correlations and multiple regression QAPs were used to identify influences of drug use homophily, and geocoding and visualizations to describe drug use polygons and PrEP conversations. Friendship relationships in which both friends used cocaine or marijuana were more likely to report PrEP-related conversations in the past six months. The likelihood of talking about PrEP in the next six months was higher among dyads with cocaine use homophily and ecstasy use homophily, while lower among dyads with marijuana use homophily. Participants reported using marijuana and cocaine throughout Miami-Dade County while ecstasy polygons were mostly in urban areas. The majority of drug polygons associated with PrEP conversations were located in north and central Miami. Future interventions can consider enrolling entire sociocentric friendship groups, configuring friendship networks to connect those without PrEP information to those with information, and incorporating peer leaders.

     

Factors Associated with Being PrEP-Naïve Among a U.S. National Cohort of Former-PrEP and PrEP-Naïve Participants Meeting Objective Criteria for PrEP Care

There is an urgent need to increase uptake and persistence in HIV pre-exposure prophylaxis (PrEP) in PrEP-eligible candidates. Little is known about the similarities and differences between groups of PrEP-naïve and former users, an important consideration for future interventions. We explored factors associated with being PrEP-naïve in a U.S. national cohort of naïve and former-PrEP users, all of whom met objective criteria for PrEP care at enrollment. Data were derived from the Together 5000 cohort study, an Internet-based U.S. national cohort of cisgender and trans men and trans women who have sex with men. Participants were recruited via ads on men-for-men geosocial networking apps. All participants were not on PrEP at the time of enrollment. We conducted bivariate analysis to explore differences between the two groups and used multivariable logistic regression to assess factors associated with being PrEP-naïve. Of the 6283 participants, 5383 (85.7%) were PrEP-naïve and 900 (14.3%) were former-PrEP users. There were significant differences between PrEP-naïve and former-PrEP users across multiple demographic variables, in addition to PrEP-related and psychosocial variables. Factors associated with being PrEP-naïve included younger age, sexual identity other than gay/queer, lower perception of candidacy for PrEP care, less willingness to take PrEP, lower access to PrEP care, and individual-level barriers such as health- and provider-related concerns. Programs and policies designed to address uptake and persistence of PrEP should be aware of these differences. Providing care in non-traditional LGBTQ-care settings, home-based PrEP interventions, and provision by healthcare providers other than physicians could improve uptake. Future research should investigate mechanisms that can improve uptake and persistence in communities in need of PrEP.
