Participants' accrual and delivery of HIV prevention interventions among men who have sex with men in sub-Saharan Africa: a systematic review

Understanding the Stigma Experience of Men Living with HIV in Sub-Saharan Africa: A Qualitative Meta-synthesis

Men living with HIV (MLWH) in sub-Saharan Africa experience poor health outcomes and increased AIDS-related deaths due to stigma influencing testing and treatment uptake and adherence. PRISMA 2020 was used to report a meta-synthesis of the stigma experiences of MLWH in SSA. With the help of an expert librarian, a search of six databases was formulated and performed to examine the available qualitative and mixed method studies with qualitative results relevant to the research question. Studies focused on adult men living with HIV, with five studies specifically examining the HIV experience of men who have sex with men. Study themes were synthesized to describe MLWH's perceived, internalized, anticipated, enacted, and intersectional stigma experiences. Most studies included masculinity as a key theme that affected both testing and treatment adherence upon diagnosis. Future research is needed to better understand subpopulations, such as men who have sex with men living with HIV, and what interventions may be beneficial to mitigate the disparities among MLWH in SSA.

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.

Determinants and acceptability of HIV self-testing among vulnerable groups in sub-Saharan Africa: A scoping review protocol

INTRODUCTION

HIV self-testing (HIVST) is where individuals collect their specimens and perform the HIV test privately. HIVST has improved testing uptake and coverage, especially among vulnerable groups of sub-Saharan Africa (SSA). Vulnerable groups include key populations such as men who have sex with men, sex workers, people who inject drugs, lesbian, gay, bisexual and transgender persons and young women. However, little is known about the determinants and acceptability of HIVST among these groups in SSA. Therefore, this scoping review aims to explore the determinants and acceptability of HIVST among vulnerable groups in SSA.

METHODS

A scoping review will be conducted using the Arksey and O'Malley framework and further refined by Levac framework. The review will follow a six-step approach: (1) identifying the research question, (2) identifying relevant studies, (3) study selection eligibility, (4) charting the data, (5) collating, summarising and reporting the results and (6) consultation. A comprehensive search strategy will be developed, and the following electronic databases will be searched: MEDLINE, Embase, Global Health and the Cochrane Library. Grey literature will also be searched, including conference abstracts and reports. Eligibility criteria will include studies conducted in SSA, published between 2010 and 2023, focusing on vulnerable groups and exploring the determinants and acceptability of HIVST. Two independent reviewers will screen identified studies' titles, abstracts and full texts. Any disagreements will be resolved through discussion or consultation with a third reviewer. Data extraction will be conducted using a standardised form.

ETHICS AND DISSEMINATION

This review, not requiring ethical approval, aims to inform policy and intervention design to boost HIV testing adoption within vulnerable communities. We plan to disseminate our findings via a peer-reviewed journal, policy briefs, conference presentations and stakeholder engagement.

Acceptability and accessibility of HIV testing and treatment among men who have sex with men in Botswana

Background: Although HIV testing and treatment are the cornerstones of a comprehensive prevention strategy, their acceptability and accessibility are complex within the healthcare system.Methods: We used Aday and Andersen's conceptual framework of access to healthcare services to explore factors influencing acceptability and accessibility of HIV testing and treatment among men who have sex with men (MSM) in Botswana. A qualitative descriptive study was conducted, using purposive sampling to recruit 20 MSM. Semi-structured interviews were conducted in Setswana and English. All data were audio-recorded, transcribed, translated into English, where necessary, and analysed using thematic analysis.Findings: This study found that acceptance of HIV testing and treatment was largely positive among MSM. Motivators were the expansion of HIV services, free healthcare services and the perceived risk of contracting HIV. Although perceptions of accessibility to HIV testing and treatment were positive, there were some concerns about privacy and confidentiality, perceived barriers and fear of positive diagnosis, making MSM reluctant to access HIV testing and treatment.Conclusion: This study highlights the need for novel approaches to increase the acceptability and accessibility of HIV testing and treatment. Barriers to accessing HIV services should be addressed to achieve satisfactory health outcomes, and sustainable HIV prevention barriers to accessing HIV should be addressed among MSM.

HIV Testing, Knowledge and Willingness to Use PrEP Among Partnered Men Who Have Sex With Men in South Africa and Namibia

There is strong evidence that gay, bisexual and other men who have sex with men (GBMSM) in African countries experience high prevalence of HIV. However, missing from the literature is an understanding of the HIV risk behaviors and prevention needs of partnered GBMSM in African countries. The Together Tomorrow project sampled 440 partnered GBMSM (220 couples) in South Africa and Namibia. Prevalence of HIV was high at 42%, with 33% of men in sero-discordant relationships. Despite high levels of HIV testing in the past 6 months (65%), condom use with main and outside sex partners was low. Men reported low levels of willingness to use pre-exposure prophylaxis (PrEP) (16%). HIV testing in the past 12 months and willingness to use PrEP were significantly associated with recent binge drinking and substance use. Men in sero-discordant relationships, those with sexual agreements and those who had experienced any form of IPV were all less likely to report that they had recently tested for HIV. There is a need to develop interventions that meet the unique needs of African partnered GBMSM and tackle stigma and discrimination as drivers of HIV risk in these settings.

Adherence to quarterly HIV prevention services and its impact on HIV incidence in men who have sex with men in West Africa (CohMSM ANRS 12324 - Expertise France)

Background

Access to tailored HIV prevention services remains limited for West African MSM. We assessed adherence to quarterly HIV prevention services and its impact on HIV incidence in MSM followed up in four cities in Burkina Faso, Côte d’Ivoire, Mali, and Togo.

Methods

We performed a prospective cohort study between 2015 and 2018. HIV-negative MSM aged over 18 benefited from quarterly medical visits which included a clinical examination, HIV testing, screening and treatment for other sexually transmitted infections, peer-led counselling and support, and the provision of condoms and lubricants. Determinants of adherence to quarterly follow-up visits and incident HIV infections were identified using generalized estimating equation models and Cox proportional hazard models, respectively.

Results

618 MSM were followed up for a median time of 20.0 months (interquartile range 15.2–26.3). Overall adherence to quarterly follow-up visits was 76.5% (95% confidence interval [CI] 75.1–77.8), ranging from 66.8% in Abidjan to 87.3% in Lomé (p < 0.001). 78 incident HIV infections occurred during a total follow-up time of 780.8 person-years, giving an overall incidence of 10.0 per 100 person-years (95% CI 8.0–12.5). Adherence to quarterly follow-up visits was not associated with the risk of incident HIV infection (adjusted hazard ratio 0.80, 95% CI 0.44–1.44, p = 0.545).

Conclusions

Strengthening HIV prevention services among MSM in West Africa, including the use of PrEP, will be critical for controlling the epidemic, not only in this key population but also in the general population. Quarterly follow-up of MSM, which is essential for PrEP delivery, appears feasible.

The feasibility of recruiting and retaining men who have sex with men and transgender women in a multinational prospective HIV prevention research cohort study in sub-Saharan Africa (HPTN 075)

INTRODUCTION

Men who have sex with men (MSM) and transgender women (TGW) in sub-Saharan Africa (SSA) are profoundly affected by HIV with high HIV prevalence and incidence. This population also faces strong social stigma and legal barriers, potentially impeding participation in research. To date, few multi-country longitudinal HIV research studies with MSM/TGW have been conducted in SSA. Primary objective of the HIV Prevention Trials Network (HPTN) 075 study was to assess feasibility of recruiting and retaining a multinational prospective cohort of MSM/TGW in SSA for HIV prevention research.

METHODS

HPTN 075, conducted from 2015 to 2017, was designed to enroll 400 MSM/TGW at four sites in SSA (100 per site: Kisumu, Kenya; Blantyre, Malawi; Cape Town, South Africa; and Soweto, South Africa). The number of HIV-positive persons was capped at 20 per site; HIV-positive persons already in care were excluded from participation. The one-year study included five biobehavioural assessments. Community-based input and risk mitigation protocols were included in study design and conduct.

RESULTS

Of 624 persons screened, 401 were enrolled. One in five participants was classified as transgender. Main reasons for ineligibility included: (a) being HIV positive after the cap was reached (29.6%); (b) not reporting anal intercourse with a man in the preceding three months (20.6%); and (c) being HIV positive and already in care (17.5%). Five (1.2%) participants died during the study (unrelated to study participation). 92.9% of the eligible participants (368/396) completed the final study visit and 86.1% participated in all visits. The main, overlapping reasons for early termination included being (a) unable to adhere to the visit schedule, predominantly because of relocation (46.4%), and (b) unable to contact the participant (32.1%). Participants reported strong motivation to participate and few participation barriers. Four participants reported social harms (loss of confidentiality and sexual harassment by study staff) that were successfully addressed.

CONCLUSIONS

HPTN 075 successfully enrolled a multinational sample of MSM/TGW in SSA in a prospective HIV prevention research study with a high retention rate and few documented social harms. This supports the feasibility of conducting large-scale research trials in this population to address its urgent, unmet HIV prevention needs.

Strategies to improve access for MSM in low-income and middle-income countries

PURPOSE OF REVIEW

HIV prevention and treatment interventions for MSM are not well studied or reported from low-income and middle-income countries (LMIC) in comparison to those targeting gender-conforming populations. Some evidence-based strategies to engage MSM in appropriate healthcare have recently reported on their experiences and impact. Novel recruitment strategies have been developed for treatment and preexposure prophylaxis (PrEP) for MSM, leveraging new community engagement strategies and social media technologies.

RECENT FINDINGS

Despite publication of several new guidelines, there is little recent evidence available to guide MSM health programs in LMIC, highlighting the need for ongoing research and publication. Some important PrEP pilot study results have recently been published, such as the PrEP Brazil and Princess PrEP programmes, which could guide the scale-up of MSM PrEP. The novel use of technology and online platforms to strengthen MSM health delivery and support is particularly important.

SUMMARY

Providing healthcare to MSM requires consideration of context, broad stakeholder engagement, implementation of best practice guidelines and ongoing situational assessment and integration of novel community engagement methods that are evidence-based. Implementation of improved antiretroviral programmes and the access to PrEP for MSM are vital.

HIV prevalence, testing and treatment among men who have sex with men through engagement in virtual sexual networks in Kenya: a cross-sectional bio-behavioural study

INTRODUCTION

In Kenya, men who have sex with men (MSM) are increasingly using virtual sites, including web-based apps, to meet sex partners. We examined HIV testing, HIV prevalence, awareness of HIV-positive status and linkage to antiretroviral therapy (ART), for HIV-positive MSM who solely met partners via physical sites (PMSM), compared with those who did so in virtual sites (either solely via virtual sites (VMSM), or via both virtual and physical sites (DMSM)).

METHODS

We conducted a cross-sectional bio-behavioural survey of 1200 MSM, 15 years and above, in three counties in Kenya between May and July 2019, using random sampling of physical and virtual sites. We classified participants as PMSM, DMSM and VMSM, based on where they met sex partners, and compared the following between groups using chi-square tests: (i) proportion tested; (ii) HIV prevalence and (iii) HIV care continuum among MSM living with HIV. We then performed multivariable logistic regression to measure independent associations between network engagement and HIV status.

RESULTS

177 (14.7%), 768 (64.0%) and 255 (21.2%), of participants were classified as PMSM, DMSM and VMSM respectively. 68.4%, 70.4% and 78.5% of PMSM, DMSM and VMSM, respectively, reported an HIV test in the previous six months. HIV prevalence was 8.5% (PMSM), 15.4% (DMSM) and 26.7% (VMSM), p < 0.001. Among those living with HIV, 46.7% (PMSM), 41.5% (DMSM) and 29.4% (VMSM) were diagnosed and aware of their status; and 40.0%, 35.6% and 26.5% were on antiretroviral treatment. After adjustment for other predictors, MSM engaged in virtual networks remained at a two to threefold higher risk of prevalent HIV: VMSM versus PMSM (adjusted odds ratio 3.88 (95% confidence interval (CI) 1.84 to 8.17) p < 0.001); DMSM versus PMSM (2.00 (95% CI 1.03 to 3.87), p = 0.040).

CONCLUSIONS

Engagement in virtual networks is associated with elevated HIV risk, irrespective of individual-level risk factors. Understanding the difference in characteristics among MSM-seeking partners in different sites will help HIV programmes to develop subpopulation-specific interventions.
