HIV incidence in a multinational cohort of men and transgender women who have sex with men in sub-Saharan Africa: Findings from HPTN 075

Interest in I-PrEP and Willingness to Participate in Clinical Trials Among Men and Transfeminine Persons Who have Sex with Men in Sub-Saharan Africa: Quantitative and Qualitative Findings from HPTN 075

This study explored interest in injectable PrEP (I-PrEP) and willingness to participate in clinical trials testing new biomedical HIV prevention strategies among men and transfeminine persons who have sex with men (MSM & TGP), using data collected in the HIV Prevention Trials Network (HPTN) 075 study, which took place at sites in Kenya, Malawi, and South Africa. Data result from a survey among 267 18-44 years old HIV negative participants, complemented with semi-structured interviews with 80 purposively recruited persons. Correlations coefficients were calculated to identify demographic and psychosocial factors associated with interest in I-PrEP. Qualitative interviews were analyzed using concept-driven and subsequent data-driven coding. Most surveyed participants expressed an interest in I-PrEP. Quantitatively, only being interested in other HIV prevention measures was associated with interest in I-PrEP. Qualitatively, most participants preferred I-PrEP to O-PrEP and remained interested in I-PrEP despite barriers such as the somewhat invasive nature of the procedure and potential side effects of I-PrEP. Interest in I-PrEP was driven by the possibility of avoiding sexual or HIV stigma. Access to healthcare and altruism-such as assisting in the development of new HIV prevention methods-positively impacted willingness to participate in clinical trials. With I-PrEP favored by most participants, it is potentially a critical tool to prevent HIV infection among MSM & TGP in sub-Saharan Africa, with the mitigation of stigma as a major advance. Recruitment of MSM & TGP in biobehavioral clinical trials seems feasible, with altruistic reasons and receiving I-PrEP and free medical care as major motivators.

Latent class analysis of barriers to HIV testing services and associations with sexual behaviour and HIV status among adolescents and young adults in Nigeria

INTRODUCTION

Adolescents and young adults (AYA) face multiple barriers to accessing healthcare services, which can interact, creating complex needs that often impact health behaviours, leading to increased vulnerability to HIV. We aimed to identify distinct AYA subgroups based on patterns of barriers to HIV testing services and assess the association between these barrier patterns and sexual behaviour, socio-demographics, and HIV status.

METHODS

Data were from Nigeria's AIDS Indicator and Impact Survey (NAIIS, 2018) and included 18,612 sexually active AYA aged 15-24 years who had never been tested for HIV and reported barriers to accessing HIV testing services. A Latent class analysis (LCA) model was built from 12 self-reported barrier types to identify distinct subgroups of AYA based on barrier patterns. Latent class regressions (LCR) were conducted to compare the socio-demographics, sexual behaviour, and HIV status across identified AYA subgroups. Sex behaviour characteristics include intergenerational sex, transactional sex, multiple sex partners, condom use, and knowledge of partner's HIV status.

RESULTS

Our LCA model identified four distinct AYA subgroups termed 'low-risk perception' (n = 7,361; 39.5%), 'consent and proximity' (n = 5,163; 27.74%), 'testing site' (n = 4,996; 26.84%), and 'cost and logistics' (n = 1,092; 5.87%). Compared to adolescents and young adults (AYA) in the low-risk perception class, those in the consent and proximity class were more likely to report engaging in intergenerational sex (aOR 1.17, 95% CI 1.02-1.35), transactional sex (aOR 1.50, 95% CI 1.23-1.84), and have multiple sex partners (aOR 1.75, 95% CI 1.39-2.20), while being less likely to report condom use (aOR 0.79, 95% CI 0.63-0.99). AYA in the testing site class were more likely to report intergenerational sex (aOR 1.21, 95% CI 1.04-1.39) and transactional sex (aOR 1.53, 95% CI 1.26-1.85). AYA in the cost and logistics class were more likely to engage in transactional sex (aOR 2.12, 95% CI 1.58-2.84) and less likely to report condom use (aOR 0.58, 95% CI 0.34-0.98). There was no significant relationship between barrier subgroup membership and HIV status. However, being female, aged 15-24 years, married or cohabiting, residing in the Southsouth zone, and of Christian religion increased the likelihood of being HIV infected.

CONCLUSIONS

Patterns of barriers to HIV testing are linked with differences in sexual behaviour and sociodemographic profiles among AYA, with the latter driving differences in HIV status. Findings can improve combination healthcare packages aimed at simultaneously addressing multiple barriers and determinants of vulnerability to HIV among AYA.

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

BACKGROUND

In South Africa, extragenital etiological sexually transmitted infection (STI) screening among men who have sex with men (MSM) is not routinely available. We aimed to determine the prevalence of STI pathogens at rectal and pharyngeal sites, syphilis seroprevalence, and associated risk factors among a selection of high-risk MSM without symptomatic urethritis attending a men's health clinic in Johannesburg, South Africa.

METHODS

A cross-sectional study was conducted in 2022. Enrolled clients self-reported demographic, sexual behavioral risks, and clinical information. Client or clinician-collected rectal and pharyngeal swabs were tested for Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma genitalium, and Trichomonas vaginalis. C. trachomatis-positive rectal samples were reflex tested for lymphogranuloma venereum. Blood specimens were screened for syphilis. Univariate and multivariate regression models were used to determine factors independently associated with the presence of an extragenital STI or syphilis.

RESULTS

Among the 97 participants (median age, 29 years), 24.7% had an extragenital STI and 9.4% had high nontreponemal antibody titers (rapid plasma reagin ≥1:16). Rectal STIs were detected in 26.4% participants: N. gonorrhoeae (14.3%), C. trachomatis (9.9%), and M. genitalium (5.5%). Pharyngeal STIs were less prevalent (4.1%). Overall, the prevalence of any STI was 41%. Sex under the influence of drugs (adjusted odds ratio, 4.94; 95% confidence interval, 1.56-15.69) and engaging in condomless receptive anal intercourse with a casual partner (adjusted odds ratio, 8.36; 95% confidence interval, 1.73-40.28) were independent risk factors for having an extragenital STI.

CONCLUSIONS

The high burden of extragenital STIs and active syphilis in asymptomatic MSM underscores the importance of routine etiological screening in this key population, as the syndromic approach would not enable detection or treatment of these infections.

Health status of transgender people globally: A systematic review of research on disease burden and correlates

BACKGROUND AND OBJECTIVES

Transgender and gender diverse (trans) health research has grown rapidly, highlighting the need to characterize the scientific evidence base. We conducted a systematic review of peer-reviewed research on disease burden and correlates in trans adolescents and adults over a 20-month period to identify knowledge gaps and assess methodological characteristics including measurement of gender identity, community engagement, and study quality.

DATA SOURCES, ELIGIBILITY CRITERIA, AND SYNTHESIS METHODS

We searched seven databases using terms related to (a) transgender populations and (b) health or disease. Eligible studies were in English, French, or Spanish and reported original quantitative data on mental health or substance use conditions, infectious diseases, or non-communicable conditions in at least 25 trans individuals aged 15+. Quality assessment was performed in duplicate on a 10% sample of articles and findings were summarized using narrative synthesis.

RESULTS

The 328 included studies were conducted in 45 countries, with most from North America (54%) and limited research from South Asia (3%), Sub-Saharan Africa (3%), and the Middle East and North Africa (2%). Most studies used cross-sectional designs (73%) and convenience sampling (65%). Only 30% of studies reported any form of community engagement. Mental health and substance use disorders were the most studied area (77% of studies) and non-communicable conditions the least (16%). Available data indicated that trans populations experience high disease burden with considerable heterogeneity within and across settings. Of 39 articles assessed for quality, 80% were rated as fair, 18% as poor, and 3% as good quality.

CONCLUSIONS AND IMPLICATIONS

Geographic, gender-specific, and topical gaps remain in trans health, but we found more research from African countries, with transmasculine people, and on non-communicable conditions than previous syntheses. Areas for growth in trans health research include community engagement, non-binary health, chronic and age-related conditions, and health determinants.

Awareness and willingness to use pre-exposure prophylaxis for HIV prevention among men who have sex with men in Rwanda: findings from a web-based survey

Introduction

Pre-exposure Prophylaxis (PrEP) is a daily pill aimed at reducing HIV transmission risk when taken as prescribed. It's highly recommended for high-risk Men who have sex with Men (MSM). This study aimed to assess PrEP awareness and willingness to use it among Rwandan MSM, a critical aspect given PrEP's proven effectiveness. The findings are expected to inform policy decisions and further advance the implementation of PrEP strategies.

Methods

This is a cross-sectional study design that utilized a web-based survey conducted between April and June 2019 to assess awareness and willingness to use PrEP among sexually active MSM in Rwanda. A snowball sampling technique was used to recruit participants via social media such as WhatsApp and e-mail. Eligibility criteria included being sexually active, aged ≥18 years, self-identifying as MSM, residing in Rwanda, self-reported engagement in receptive or insertive anal sex in the last 12 months, and self-reported HIV-negative serostatus. We assessed two primary outcomes: PrEP awareness (having ever heard of PrEP) and willingness to use PrEP within one month of completing the survey. Multivariable logistic regression was performed to identify participant characteristics associated with PrEP awareness and willingness to use it.

Results

Out of 521 participants, the majority (73%) demonstrated awareness of PrEP. Factors linked to PrEP awareness included residing outside the capital, Kigali, being in the 18-29 age group, having higher education levels, perceiving a benefit from PrEP, and engaging in vaginal sex with a woman while using a condom in the last year. Additionally, 96% of participants expressed a strong willingness to use PrEP.

Conclusion

Rwandan MSM exhibits a high level of PrEP awareness, notably associated with factors like location, age, education, perceived benefits, and condom use. The study also revealed a strong willingness to use PrEP, indicating promising prospects for its adoption among this group. These findings highlight the need for targeted awareness campaigns, personalized interventions, and comprehensive sexual health education to promote PrEP adoption and strengthen HIV prevention efforts among Rwandan MSM.

Comparison of Empirically Derived and Model-Based Estimates of Key Population HIV Incidence and the Distribution of New Infections by Population Group in Sub-Saharan Africa

BACKGROUND

The distribution of new HIV infections among key populations, including female sex workers (FSWs), gay men and other men who have sex with men (MSM), and people who inject drugs (PWID) are essential information to guide an HIV response, but data are limited in sub-Saharan Africa (SSA). We analyzed empirically derived and mathematical model-based estimates of HIV incidence among key populations and compared with the Joint United Nations Programme on HIV/AIDS (UNAIDS) estimates.

METHODS

We estimated HIV incidence among FSW and MSM in SSA by combining meta-analyses of empirical key population HIV incidence relative to the total population incidence with key population size estimates (KPSE) and HIV prevalence. Dynamic HIV transmission model estimates of HIV incidence and percentage of new infections among key populations were extracted from 94 country applications of 9 mathematical models. We compared these with UNAIDS-reported distribution of new infections, implied key population HIV incidence and incidence-to-prevalence ratios.

RESULTS

Across SSA, empirical FSW HIV incidence was 8.6-fold (95% confidence interval: 5.7 to 12.9) higher than total population female 15-39 year incidence, and MSM HIV incidence was 41.8-fold (95% confidence interval: 21.9 to 79.6) male 15-29 year incidence. Combined with KPSE, these implied 12% of new HIV infections in 2021 were among FSW and MSM (5% and 7% respectively). In sensitivity analysis varying KPSE proportions within 95% uncertainty range, the proportion of new infections among FSW and MSM was between 9% and 19%. Insufficient data were available to estimate PWID incidence rate ratios. Across 94 models, median proportion of new infections among FSW, MSM, and PWID was 6.4% (interquartile range 3.2%-11.7%), both much lower than the 25% reported by UNAIDS.

CONCLUSION

Empirically derived and model-based estimates of HIV incidence confirm dramatically higher HIV risk among key populations in SSA. Estimated proportions of new infections among key populations in 2021 were sensitive to population size assumptions and were substantially lower than estimates reported by UNAIDS.

Awareness and Willingness to Use HIV Infection Pre-Exposure Prophylaxis among Rwandan Men Who Have Sex with Men: Findings from a Web-based Survey

Introduction

Pre-exposure Prophylaxis (PrEP) is a daily pill intended to reduce the risk of acquiring Human Immunodeficiency Virus (HIV) when taken as prescribed. It is strongly recommended for Men who have sex with Men (MSM) at high risk of HIV transmission to minimize infection risk. Despite its proven effectiveness, there is a lack of information about awareness and willingness to use PrEP among Rwandan MSM. In the context of HIV acquisition, the purpose of this study was to ascertain the awareness and willingness to use PrEP among high-risk Rwandan MSM. The findings of this research will provide valuable perspectives to mold policy and direct the effective execution of PrEP within the country.

Method

This is a cross-sectional study design that utilized a web-based survey conducted between April and June 2019 to assess awareness and willingness to use PrEP among sexually active MSM in Rwanda. A snowball sampling technique was used to recruit participants who were contacted via social medial such as WhatsApp and e-mail. To be eligible, participants were supposed to be sexually active, aged ≥18 years, self-identify as MSM, residence in Rwanda, self-reported engagement in receptive or insertive anal sex in the last 12 months, and self-reported HIV-negative sero-status. We assessed two primary outcomes: PrEP awareness (having ever heard of PrEP) and willingness to use PrEP within one month of completing the survey. Multivariable logistic regression was performed to identify participant characteristics associated with PrEP awareness and willingness to use it.

Results

Among the 521 participants included in the analysis, 63% were aged below 24 years. The majority (73%) demonstrated awareness of PrEP. Factors associated with PrEP awareness included residing outside of the capital, Kigali, as opposed to living in Kigali (adjusted odds ratio [aOR] 2.35, 95% confidence interval [CI] 1.40-3.97), being in the age groups 18-24 years (aOR 2.28, 95% CI: 1.03-5.01) or 25-29 years (aOR 3.06, 95% CI 1.35-6.93) compared to those aged 30 or older, having higher education levels, such as completing secondary education (aOR 1.76, 95% CI 1.01-3.06) or university education (aOR 2.65, 95% CI 1.18-5.96) in contrast to having no education. Lastly, perceiving a benefit from PrEP (aOR 9.52, 95% CI 4.27-21.22), and engaging in vaginal sex with a woman using a condom in the last 12 months (aOR 1.82, 95% CI 1.14-2.91) versus not. Impressively, 96% of participants expressed a strong willingness to use PrEP.

Conclusion

Among Rwandan MSM, there is a high level of awareness of PrEP, notably associated with factors such as residing outside Kigali, younger age, higher education, perceived benefits of PrEP and condom use during vaginal sex in the past year. Furthermore, a significant portion of participants demonstrated an intense desire to use PrEP, suggesting promising possibilities for its extensive implementation among this group of people. The findings from this study emphasize the importance of implementing highly focused awareness campaigns, personalized intervention, and comprehensive sexual health education programs in order to enhance the adoption of PrEP and bolster HIV prevention initiatives among the Rwandan population of MSM.

Information, Motivation and Behavioral Skills as Mediators Between Sexual Minority Stigma and Condomless anal Sex Among Black South African Men Who have Sex with Men

We assessed pathways between sexual minority stigma and condomless anal intercourse (CAI) among two samples of Black South African men who have sex with other men (MSM). Two cross-sectional surveys were conducted in Tshwane, South Africa; one among 199 Black MSM and another among 480 Black MSM. Men reported on external and internalized experiences of sexual minority stigma, mental health, alcohol use, information-motivation-behavioral skills (IMB) model constructs, and CAI. Structural equation modeling was used to test whether external and internalized stigma were directly and indirectly associated with CAI. In both studies, external stigma and internalized stigma were associated with CAI through IMB model constructs. These results suggest a pathway through which stigma contributes to HIV risk. For HIV prevention efforts to be effective, strengthening safer sex motivation and thus decreasing sexual risk behavior likely requires reducing sexual minority stigma that MSM experience and internalize.

The social and sexual lives of Black sexual minority men 30 years of age and older in South Africa

Background

Black sexual minority men (SMM) ages 30 and older are under-represented in HIV studies in sub-Saharan Africa, despite being at increased risk of HIV infection and contributing to potential onward HIV transmission. To better understand the social and sexual lives of older Black South African SMM, we conducted in-depth interviews with SMM who were > 30 years old.

Methods

From March–September 2016, we recruited a convenience sample of 37 SMM ages 30 and older by partnering with an LGBTQ+ organization in Tshwane, Pretoria. Men were interviewed about various aspects of their lives, including their sexual orientation, social connectedness, experiences with stigma and perspectives on participating in research.

Results

Participants described their experiences with their sexual identities, cultural and social implications of disclosure, and their perspective on South Africa’s political perspectives on the LGBTQ+ community. Men described how these experiences influence their trust in research and comfort participating in studies.

Conclusions

Inferences drawn from these findings provide direction on how to improve middle-aged SMM’s representation in research, such as recruiting a higher proportion of older and middle-aged SMM to serve as seed participants and building stronger community partnerships to disseminate study findings to settings where data collection is conducted.

A qualitative study of how stigma influences HIV services for transgender men and women in Nigeria

INTRODUCTION

Transgender men and women in Nigeria experience many barriers in accessing HIV prevention and treatment services, particularly given the environment of transphobia (including harassment, violence and discrimination) and punitive laws in the country. HIV epidemic control in Nigeria requires improving access to and quality of HIV services for key populations at high risk, including transgender men and women. We assessed how stigma influences HIV services for transgender people in Lagos, Nigeria.

METHODS

In-depth interviews (IDIs) and focus group discussions were conducted with transgender men (n = 13) and transgender women (n = 25); IDIs were conducted with community service organization (CSO) staff (n = 8) and healthcare providers from CSO clinics and public health facilities (n = 10) working with the transgender population in March 2021 in Lagos. Content analysis was used to identify how stigma influences transgender people's experiences with HIV services.

RESULTS AND DISCUSSION

Three main findings emerged. First, gender identity disclosure is challenging due to anticipated stigma experienced by transgender persons and fear of legal repercussions. Fear of being turned in to authorities was a major barrier to disclose to providers in facilities not affiliated with a transgender-inclusive clinic. Providers also reported difficulty in eliciting information about the client's gender identity. Second, respondents reported lack of sensitivity among providers about gender identity and conflation of transgender men with lesbian women and transgender women with being gay or men who have sex with men, the latter being more of a common occurrence. Transgender participants also reported feeling disrespected when providers were not sensitive to their pronoun of preference. Third, HIV services that are not transgender-inclusive and gender-affirming can reinforce stigma. Both transgender men and women spoke about experiencing stigma and being refused HIV services, especially in mainstream public health facilities, as opposed to transgender-inclusive CSO clinics.

CONCLUSIONS

This study highlights how stigma impedes access to appropriate HIV services for transgender men and women, which can have a negative impact along the HIV care continuum. There is a need for transgender-inclusive HIV services and competency trainings for healthcare providers so that transgender clients can receive appropriate and gender-affirming HIV services.

Controversies and evidence on Chlamydia testing and treatment in asymptomatic women and men who have sex with men: a narrative review

Background

Chlamydia trachomatis (CT) is the most common bacterial sexually transmitted infection (STI) worldwide. CT is mainly asymptomatic. Test-and-treat strategies are widely implemented to prevent transmission and complications. Strategies are not without controversy in asymptomatic women and men who have sex with men (MSM). Concerns are emerging to test and treat asymptomatic persons for urogenital CT (‘Controversy 1’) and pharyngeal or rectal CT (‘Controversy 2’), whereby testing symptomatic persons is not under debate. Opposed views in CT treatment involve using azithromycin versus doxycycline (‘Controversy 3’). The objective of this review is to provide coverage of these public health and clinical controversies by reviewing the current scientific evidence.

Methods

A literature search was performed using PubMed for relevant publications between 2018 and September 2021, and iterative retrieval of additional relevant publications.

Results

Controversy 1. In women, the majority of asymptomatic CT are at the urogenital site, and detections mostly include viable CT. CT easily transmits to a partner and potentially also between the vaginal and rectal areas; the clinical impact of urogenital CT is established, although risks for adverse outcomes are uncertain. Wide-scale testing in asymptomatic women has not resulted in reduced prevalence. In MSM, evidence for the clinical impact of asymptomatic urogenital CT is lacking. Controversy 2. Rectal CT is common in women diagnosed with urogenital CT, but the clinical impact of asymptomatic rectal CT is uncertain. In MSM, rectal CT is common, and most CT infections are at the rectal site, yet the risk of longer term complications is unknown. In both sexes, pharyngeal CT is uncommon and has no documented clinical impact. Controversy 3. In the treatment of rectal CT, doxycycline has superior effectiveness to azithromycin. Evidence has also accumulated on the harms of test-and-treat strategies.

Conclusions

Current practices vary widely, from widescale test-and-treat approaches to more individual patient- and partner-level case management. Choosing which asymptomatic people to test at what anatomic site, and whether to test or not, requires an urgent (re-)definition of the goals of testing and treating asymptomatic persons. Treatment guidelines are shifting toward universal doxycycline use, and clinical practice now faces the challenge of implementation.

Supplementary Information

The online version contains supplementary material available at 10.1186/s12879-022-07171-2.

Test-and-treat is a key strategy in the control of Chlamydia trachomatis (CT). We discuss recent controversies and present scientific evidence regarding urogenital, rectal, and pharyngeal CT test-and-treat strategies in women and in men who have sex with men (MSM). This should inform best practices for the prevention and management of the most common bacterial sexually transmitted infection (STI) worldwide.

Sexual Prejudice and Comfort to Provide Services to Men Who Have Sex with Men Among HIV Healthcare Workers in Western Kenya: Role of Interpersonal Contact

Sexual minority men living in Africa, where many countries criminalize same-sex behavior, are vulnerable to HIV and experience significant barriers to HIV care. Sexual prejudice in healthcare settings is a key contributor to these barriers. Building on social psychological models of prejudice and interpersonal contact at the clinic, we examined the associations between healthcare workers' sexual prejudice and their comfort to provide care to MSM, and assessed the moderating role of workers' prior interpersonal contact with MSM. A cross-sectional survey of 147 healthcare workers varying in level of training and expertise working in HIV care organizations was conducted in western Kenya. Sexual prejudice was negatively associated with comfort to provide care to MSM. Prior interpersonal contact with MSM moderated the association between sexual prejudice and comfort to provide care to MSM among nurses/counselors, such that those with low prior contact and high sexual prejudice were the most uncomfortable providing care to MSM. Interventions are needed to address sexual prejudice and encourage positive forms of interpersonal contact with MSM, especially with nurses and counselors who might have more and varied patient interactions, to improve access to the continuum of HIV prevention and care for MSM in Kenya.
