Abstract
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.

Men Who Have Sex with Both Men and Women in West Africa: Factors Associated with a High Behavioral Risk of Acquiring HIV from Male Partners and Transmission to Women (CohMSM ANRS 12324-Expertise France). ARCHIVES OF SEXUAL BEHAVIOR 2024; 53:757-769. [PMID: 37973698 PMCID: PMC10844348 DOI: 10.1007/s10508-023-02715-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Revised: 09/13/2023] [Accepted: 09/21/2023] [Indexed: 11/19/2023]
Abstract
HIV is highly prevalent in men who have sex with men (MSM) in West Africa. Many MSM in the region also have sex with women (MSMW). Accordingly, they are a potential bridge subpopulation for HIV transmission to women. We aimed to evaluate the proportions and characteristics of West African MSMW at high behavioral risk of acquiring HIV from male partners and transmitting it to female partners (HBRMF). The cohort ANRS-12324 CohMSM Study included 630 HIV-negative MSM in Burkina Faso, Cote d'Ivoire, Mali, and Togo. Among MSMW (i.e., with ≥ 1 female partner) in the cohort, HBRMF was identified using trajectory models based on seven at-risk sexual practices with male and female partners, including inconsistent condom use, multiple partnerships, and receptive same-sex anal intercourse. To assess the relevance of using trajectory models, we compared the proportions of participants who seroconverted during the cohort follow-up among those at HBRMF and those not at HBRMF. Factors associated with HBRMF were identified using a generalized estimation equation logistic regression model accounting for longitudinal data. Approximately half (47%) of the 304 MSMW (22% of all CohMSM study participants) were at HBRMF. This group accounted for 75% of the 28 HIV seroconversions observed during follow-up (p = 0.001). HBRMF was positively associated with being aged < 25 years (aOR 95% CI 1.67 [1.23-2.27]), being sexually attracted only to men (1.97 [1.38-2.78]), feelings of loneliness (1.92 [1.38-2.65]), and homonegative violence score (1.22 [1.05-1.41]). HBRMF was negatively associated with having had both stable and casual female partners in the previous 6 months (0.34 [0.20-0.60] vs. only a stable female partner). HBRMF tended to be negatively associated with having ≥ 4 sexual intercourses with female partners in the previous four weeks (0.54 [0.27-1.06] vs. no intercourse). Establishing official relationships with women might be a strategy for young and/or stigmatized MSMW to comply with social pressure to display a heterosexual lifestyle. However, this seems to increase the risk of HIV transmission to female partners. In the present study, almost half of MSMW were at HBRMF. This result stresses the need to adapt HIV research and prevention to MSMW and their female partners.

Abstract
Transgender women (TGW) and men who have sex with other men (MSM) often encounter disparities in accessing HIV testing, leading to delayed diagnoses and worse prognoses. We analysed barriers and facilitators for accessing HIV rapid testing by TGW and MSM in Brazil, 2004-2023. Citations were included whether the study population consisted of individuals aged ≥18y old, and studies addressed HIV testing and have been conducted in Brazil. The study protocol was based on Joanna Briggs' recommendations for scoping reviews. We included 11 studies on TGW and 17 on MSM. The belief that one is not at risk of contracting HIV infection, fear expressed in different ways (e.g. lack of confidentiality) and younger age were the main barriers. Feeling at risk for HIV infection, curiosity, and favourable characteristics of the setting where the testing takes place were cited as the main facilitators. Barriers and facilitators specifically for HIV self-testing included, respectively, concerns about conducting the test alone vs. autonomy/flexibility. Brazil is unlikely to achieve the UN' 95-95-95 goal without minimising testing disparities. Combating prejudice against TGW and MSM in testing settings, along with educational campaigns and transparent protocols to ensure confidentiality, can help increase HIV testing among these populations.

Abstract
Young men who have sex with men (YMSM) in Nigeria are ten times more likely to be living with HIV-1 than other young men. Due to stigma and criminalization of same-sex sexual behavior, YMSM sexual networks are likely to overlap with those of the general population, leading to a generalized HIV-1 epidemic. Due to limited research on social/sexual network dynamics related to HIV-1 in Nigeria, our study focused on YMSM and sought to assess the feasibility and acceptability of collecting social and sexual network data in Network Canvas from individuals newly diagnosed with HIV-1 in Ibadan, Nigeria. The Network Canvas software was piloted at three sites in Ibadan, Nigeria to collect social/sexual network data from 151 individuals newly diagnosed with HIV-1. Our study sample included 37.7% YMSM; participants reported a mean of 2.6 social alters and 2.6 sexual alters. From the 151 egos and 634 alters, 85 potential unique individuals (194 total) were identified; 65 egos/alters were collapsed into 25 unique individuals. Our success collecting network data from individuals newly diagnosed with HIV-1 in Ibadan demonstrates clear feasibility and acceptability of the approach and the use of Network Canvas to capture and manage these data.

Abstract
Bimonthly long-acting injectable pre-exposure prophylaxis (LAI-PrEP) can become an important additional tool for HIV prevention among West African men who have sex with men (MSM). The objective was to explore the perceived added value of LAI-PrEP as an HIV prevention tool among MSM in Burkina Faso, Côte d'Ivoire, Mali, and Togo. We conducted eight focus group discussions among 62 HIV-negative MSM between April and May 2021. Participants were recruited via local community-based clinics. Data collection and analysis were guided by grounded theory and community-based participatory approaches. Participants were generally knowledgeable about HIV, and explained particular barriers for HIV prevention in their communities (e.g., denial of HIV). The added value of LAI-PrEP relative to condoms was similar to oral pre-exposure prophylaxis (PrEP) in terms of perceived advantages (e.g., improved sexual satisfaction) or disadvantages (e.g., no protection against other sexually transmitted infections). Compared with oral PrEP, LAI-PrEP was perceived to provide better protection against HIV and to be more convenient (e.g., no need to be mindful of intake and less risk for stigma). Concerns included fear of needles, doubts about efficacy, potential side effects, and difficulties for ensuring timely injections (e.g., when traveling abroad). The results demonstrate that injectable PrEP can be of particular interest to subgroups of West African MSM, although existing HIV prevention tools such as condoms and oral PrEP will remain valuable alongside of, or instead of, LAI-PrEP. Increasing awareness about HIV and tackling discrimination based on sexual orientation continue to be crucial factors to be addressed for HIV prevention.

Abstract
Our objective was to assess factors associated with health-related quality of life (HRQoL) among men who have sex with men (MSM) living with or those not living with HIV in Nigeria. A cross-sectional subset of adult MSM in the ongoing TRUST/RV368 HIV prevention and treatment study were recruited and completed the World Health Organization quality of life in HIV infection (WHOQOL-BREF) questionnaire. The tool comprises physical health, psychological health, social relationships and environmental health domains from which scores were extracted. T-tests were used to compare mean HRQoL scores between participants living with or those not living with HIV and among persons living with HIV who had been on antiretroviral therapy for ≥1 year or <1 year. Of 322 study participants, 186 (57.8%) were living with HIV. The mean scores were significantly lower for participants living with HIV as compared to those not living with HIV in physical health, psychological health and social relationship domains. Among persons living with HIV and taking ART, scores were significantly lower for those whose duration was <1 year as compared to ≥1 year regarding physical health and psychological health. Strategies to improve HIV prevention and early detection and linkage to HIV care may improve HRQoL.

Abstract
Key populations (KPs) are particularly vulnerable to HIV infection and efforts to prevent HIV infections among KPs have been less successful, largely due to existing laws and legislation that classify the groups as illegal. Understanding the HIV infection pathway and the burden of HIV infection among Female Sex Workers (FSWs), Transgender people (TG), Men who have sex with Men (MSM), People who Inject Drugs (PWID), and Prison Inmates (PIs) is critical to combatting the HIV epidemic globally. This study aims to estimate HIV prevalence and model the risk factors of HIV positivity rate among the aforementioned KPs in Sierra Leone. This study used Time Location Sampling, Respondent Driven Sampling (RDS), and Conventional cluster Sampling designs to generate a representative sample of FSWs, MSM, TG, PI, and PWID. HIV prevalence and the corresponding 95% confidence intervals among each KP were estimated by adjusting for sampling weight using the logit-transformed confidence intervals. To determine correlates of HIV test positivity among KPs, a multivariable modified Poisson regression model that adjusts for RDS survey weights was used and sensitivity analysis was conducted using a multivariable logistic regression model with cluster robust standard errors. The prevalence of HIV among FSWs in the six regional headquarter towns was estimated to be 11.8% (95% CI: 7.9-17.1); MSM was 3.4% [95% CI: 1.9-5.8]; TGs was 4.2% (95% CI: 2.9-6.1); PWIDs was 4.2% (95% CI: 2.7-6.4) and PI was 3.7% (95% CI: 1.4-9.6). The correlates of HIV test positivity among KPs and PIs include HIV-related knowledge, marital status, district, income, age and sex of KP, level of education, alcohol intake, injecting drugs, and use of lubricants. HIV prevalence is relatively high among FSWs, MSMs, PWID, and TGs as compared to the previous estimate of the general population. There is a need to scale up and strengthen evidence-based HIV prevention interventions such Pre-Exposure Prophylaxis and needle and syringe exchange programmes targeting KPs, including prison inmates. Government must scale up both non-clinical and clinical routine HIV and STI testing and counseling services at the correctional center and drop-in centers for KPs screening/testing, and ensure that services are responsive to the needs of KP.

Abstract
BACKGROUND Preexposure prophylaxis (PrEP) is effective in preventing human immunodeficiency virus (HIV) infection among sexual and gender minorities (SGMs). We evaluated the characteristics associated with engagement in 7 steps of the PrEP cascade among SGMs in Nigeria. METHODS Sexual and gender minorities without HIV from the Abuja site of TRUST/RV368 cohort who were surveyed on awareness of and willingness to use PrEP were approached for PrEP initiation upon availability of oral daily PrEP. To understand gaps in the uptake of oral daily PrEP, we categorized the HIV PrEP cascade as (i) education about PrEP, (ii) interest in PrEP, (iii) successful contact, (iv) appointment scheduled, (v) appointment attendance, (vi) PrEP initiation, and (vii) plasma protective levels of tenofovir disoproxil fumarate. Multivariable logistic regression models were used to determine factors associated with each of the 7 steps in the HIV PrEP cascade. RESULTS Of 788 participants, 718 (91.1%) showed interest in taking oral daily PrEP every day and/or after a sexual act, 542 (68.8%) were successfully contacted, 433 (54.9%) scheduled an appointment, 409 (51.9%) attended a scheduled appointment, 400 (50.8%) initiated oral daily PrEP, and 59 (7.4%) had protective levels of tenofovir disoproxil fumarate. Of initiators of PrEP, 23 (5.8%) seroconverted at a rate of 13.9 cases/100 person-years. Better social support, larger network density, and higher education were associated with engagement in 4 to 5 components of the cascade. CONCLUSIONS Our data highlight a gap between willingness and actual PrEP use. Despite PrEP's effectiveness in preventing HIV, the optimal impact of PrEP for SGMs in sub-Saharan Africa will require multifaceted approaches that combine social support, education, and destigmatization.

Clin Infect Dis 2023; 77:606-614. [PMID: 37052469 DOI: 10.1093/cid/ciad221] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Revised: 04/03/2023] [Accepted: 04/11/2023] [Indexed: 04/14/2023] Open
Abstract
BACKGROUND Data on human immunodeficiency virus (HIV) seroconversion among men who have sex with men (MSM) using pre-exposure prophylaxis (PrEP) in West Africa are needed. This study aimed to document HIV seroconversion and associated determinants, PrEP adherence, plasma drug concentrations, and HIV drug resistance in MSM using event-driven or daily PrEP in Burkina Faso, Côte d'Ivoire, Mali, and Togo. METHODS A prospective cohort study was conducted in 2017-2021 among HIV-seronegative MSM aged 18 or over who were at high risk of HIV infection. Participants could choose between event-driven and daily PrEP, switch regimens, and discontinue or restart PrEP. The determinants of HIV incidence were investigated using a multivariate mixed-effects Poisson regression analysis. RESULTS A total of 647 participants were followed for a total time of 1229.3 person-years. Of 5371 visits, event-driven PrEP was chosen in 3873 (72.1%), and daily PrEP in 1400 (26.1%). HIV incidence was 2.4 per 100 person-years (95% confidence interval [CI] 1.5-3.6) for event-driven PrEP, and 0.6 per 100 person-years (95% CI .1-2.3) for daily PrEP (adjusted incidence rate ratio 4.40, 95% CI 1.00-19.36, P = .050). Adequate adherence was lower with event-driven than daily PrEP (44.3% vs 74.9%, P < .001). Plasma drug concentrations were undetectable in 92 (97.9%) of the 94 measures taken for 23 participants who seroconverted. Only 1 participant had resistance to PrEP drugs. CONCLUSIONS HIV seroconversions mainly occurred in participants who chose event-driven PrEP. The study's data highlighted major difficulties with adherence to this regimen. Improving adherence to event-driven PrEP constitutes a major research and public health priority in this context.

Abstract
BACKGROUND People living with HIV are vulnerable to cardiometabolic diseases. We assessed the prevalence of cardiometabolic risk factors (CMRF) and associations with sexual stigma and depression among sexual and gender minorities (SGM) in Abuja and Lagos, Nigeria. METHODS The TRUST/RV368 study enrolled SGM between March 2013 and February 2020. Participants were assessed for depression, sexual stigma, and CMRF. Robust multinomial logistic regression was used to estimate adjusted odds ratio (aORs) and 95% confidence intervals (CIs) for associations of depression, sexual stigma, and other factors with increasing numbers of CMRF. RESULTS Among 761 SGM, the mean age was 25.0 ± 6.0 years; 580 (76%) identified as cisgender men, 641 (84%) had ≥1 CMRF, 355 (47%) had mild-severe depression, and 405 (53%) reported moderate-high sexual stigma. Compared with individuals without depression, those with mild (aOR 8.28; 95% CI: 4.18 to 16.40) or moderate-severe depression (aOR 41.69; 95% CI: 9.60 to 181.04) were more likely to have 3-5 CMRF. Individuals with medium (aOR 3.17; 95% CI: 1.79 to 5.61) and high sexual stigma (aOR 14.42; 95% CI: 2.88 to 72.29) compared with those with low sexual stigma were more likely to have 3-5 CMRF. Participants age 25-34 years were less likely to have 3-5 CMRF (aOR 0.41; 95% CI: 0.23 to 0.73) compared with participants age younger than 25 years. CONCLUSION CMRF increased with severity of depression and sexual stigma, potentially predisposing SGM living with HIV to cardiometabolic diseases. Integrating interventions that address depression and sexual stigma in HIV care programs for SGM may improve cardiometabolic outcomes.

Abstract
INTRODUCTION In sub-Saharan Africa, as in the rest of the world, men who have sex with men (MSM) are at greater risk of HIV infection than the general population. Bisexuals are often perceived to be more at risk than exclusive gay men. PURPOSE OF RESEARCH We propose a review of epidemiological surveys conducted in sub-Saharan Africa since 2005 to provide an overview of knowledge on HIV exposure among gay/bisexual men. RESULTS We reviewed 355 publications and identified 62 measures of the association between bisexuality and HIV prevalence and 8 measures of the association between bisexuality and incidence. Except for 4 of 62 measures, the HIV prevalence observed among bisexuals was equal to or lower than that observed among exclusive gay men. In terms of incidence, all but one of the identified studies observed lower or equal HIV incidence among bisexuals. From a behavioural perspective, most studies found no difference in condom use. Bisexuals may have less frequent sex and consistently less receptive anal sex. They mainly started their sexual lives with men later, had fewer partners, and were less likely to know their HIV status. CONCLUSIONS Bisexuals are less likely to be at risk of HIV than exclusive gay men, partly because of behavioural differences. Prevention and treatment programs for MSM must take the specificities of bisexuals into account and design differentiated services.

Abstract
Introduction Transgender and gender‐diverse communities in Zambia are highly vulnerable and experience healthcare differently than cisgender persons. The University of Maryland, Baltimore (UMB) supports projects in Zambia to improve HIV case‐finding, linkage and antiretroviral treatment (ART) for Zambia's transgender community. We describe programme strategies and outcomes for HIV prevention, testing and ART linkage among transgender communities. Methods UMB utilizes a differentiated service delivery model whereby community health workers (CHWs) recruited from key populations (KPs) reach community members through a peer‐to‐peer approach, with the support of local transgender civil society organizations (CSOs) and community gatekeepers. Peer CHWs are trained and certified as HIV testers and psychosocial counsellors to offer counselling with HIV testing and prevention services in identified safe spaces. HIV‐negative people at risk of HIV infection are offered pre‐exposure prophylaxis (PrEP), while those who test positive for HIV are linked to ART services. CHWs collect data using the standardized facility and community tools and a dedicated DHIS2 database system. We conducted a descriptive analysis examining HIV testing and prevention outcomes using proportions and comparisons by time period and geographic strata. Results From October 2020 to June 2021, across Eastern, Lusaka, Western and Southern Provinces, 1860 transgender persons were reached with HIV prevention messages and services. Of these, 424 (23%) were tested for HIV and 78 (18%) tested positive. Of the 346 HIV‐negative persons, 268 (78%) eligible transgender individuals were initiated on PrEP. ART linkage was 97%, with 76 out of the 78 transgender individuals living with HIV initiating treatment. Programme strategies that supported testing and linkage included peer CHWs, social network strategy testing, same‐day ART initiation and local KP CSO support. Challenges included non‐transgender‐friendly environments, stigma and discrimination, the high transiency of the transgender community and the non‐availability of transgender‐specific health services, such as hormonal therapy. Conclusions Peer KP CHWs were able to reach many members of the transgender community, providing safe HIV testing, PrEP services and linkage to care. Focusing on community gatekeepers and CSOs to disburse health messages and employ welcoming strategies supported high linkage to both PrEP and ART for transgender people in Zambia.

Abstract
Sexual minority men (SMM) in Nigeria have been disproportionately affected by HIV. Pre-exposure prophylaxis (PrEP) reduces risk for HIV acquisition among SMM by over 90%. The current study investigated the association between demographics, socioeconomic marginalization, sexual health and willingness to use long-acting injectable (LAI-) PrEP and preferences for other PrEP modalities in a sample of HIV-negative SMM in Nigeria. Between March and June 2019, SMM residing in Abuja, Delta, Lagos, and Plateau completed a quantitative survey. To examine willingness to use LAI-PrEP and PrEP modality preferences, multivariable binomial and multinomial logistic regression models were fit. We found that 88% were willing to use LAI-PrEP and 44% preferred LAI-PrEP to other PrEP modalities. Participants who reported interest in LAI-PrEP were more likely to be single, engage in inconsistent condom use, and report having a primary care provider. Compared to participants who preferred daily oral PrEP, participants who preferred other PrEP modalities had higher odds of having some university education/university degree or higher and reporting low financial hardship. It is imperative that SMM in Nigeria are prioritized for access to new HIV prevention interventions, as they bear a disproportionate burden of HIV and are especially vulnerable to HIV infection.

Abstract
IMPORTANCE Nigeria has the fourth-largest HIV epidemic globally, yet high levels of social stigma inhibit HIV testing among Nigerian youths and young men who have sex with men (MSM). OBJECTIVE To report pilot data from iCARE Nigeria (Intensive Combination Approach to Roll Back the Epidemic in Nigerian Adolescents), a combination intervention using social media and peer navigation to promote HIV testing and linkage to care among high-risk youths and young men (hereinafter referred to as young men), including predominantly young MSM. DESIGN, SETTING, AND PARTICIPANTS This nonrandomized controlled study assessed an organizational and community-level 12-month, preintervention-postintervention pilot trial of a combination intervention designed to increase HIV testing uptake, increase the rate of identified seropositive cases, and improve linkage to care among young men, including MSM, using social media outreach and peer navigation. Data were collected from June 1, 2019, to May 30, 2020. Participants were young men aged 15 to 24 years in the city of Ibadan, Nigeria, and surrounding areas. Frequencies and percentages were examined, and a Fisher exact test was used to evaluate outcomes compared with historical surveillance data. Linkage to care was defined as 2 clinic visits, including HIV confirmation, within 2 months of a positive rapid test result. INTERVENTION Four peer navigators conducted social media outreach promoting sexual health and guiding individuals to HIV counseling and rapid testing in clinical, community, or home-based settings. MAIN OUTCOMES AND MEASURES Primary outcomes included the number of young men tested for HIV at university-based iCARE catchment clinics or by iCARE peer navigators in the community, the postintervention HIV seroprevalence of these groups, and linkage to care of participants diagnosed with HIV infection. RESULTS A total of 339 participants underwent testing for HIV (mean [SD] age, 21.7 [1.9] years), with 283 (83.5%) referred through social media. The main referral sources for social media were WhatsApp (124 [43.8%]), Facebook (101 [35.7%]), and Grindr (57 [20.1%]). Regarding testing location, participants chose home (134 [39.5%]), community-based (202 [59.6%]), or clinic (3 [0.9%]) settings. Eighty-six participants reported no prior HIV testing. Thirty-six participants (10.6%) were confirmed as HIV seropositive; among those, 18 (50.0%) reported negative test results within the past year, and 31 (86.1%) were linked to care. In two 6-month follow-up periods, the intervention increased HIV testing by 42% and 31%, respectively, and seroprevalence increased compared with historical trends with odds ratios of 3.37 (95% CI, 1.43-8.02; P = .002) and 2.74 (95% CI, 1.10-7.11; P = .02), respectively. CONCLUSIONS AND RELEVANCE These findings suggest that use of iCARE Nigeria was associated with increased HIV testing and linkage to care in a high-risk, difficult-to-reach population, making it a promising combination intervention for young MSM.

Abstract
Young men who have sex with men (YMSM) under 25 years old are among the few populations with increasing numbers of new HIV infections in parts of the world where HIV incidence is declining overall. In this systematic review, we synthesize the literature on HIV prevalence among MSM in Latin America and the Caribbean focusing on YMSM. Results were stratified according to study population sampling method used (probability and non-probability based). Forty-seven studies from 17 countries were published in the last 10 years. Among studies using probability-based sampling method (N = 21), HIV prevalence among MSM ranged from 1.2 to 32.6%. HIV prevalence tended to increase over time in studies sampling at different time points. HIV prevalence among YMSM exceeded 5.0% in more than a half of studies (51%; N = 22/43). Our review corroborates the high and potentially rising incidence of HIV among YMSM and characterizes the region's greatest challenge to ending the epidemic.

Abstract
Transgender women (TW) and men who have sex with men (MSM) in Kenya are disproportionately affected by human immunodeficiency virus (HIV) and would benefit substantially from pre-exposure prophylaxis (PrEP). We conducted focus group discussions (FGDs) with healthcare providers (HCPs) and TW/MSM leadership and in-depth interviews (IDIs) with PrEP-experienced MSM and TW to learn about perceived and actual barriers to PrEP programming. Eleven HCP and 10 TW/MSM leaders participated in FGDs before PrEP roll-out (January 2018) and 12 months later. Nineteen PrEP end-users (11 MSM and 8 TW) participated in IDIs. Topic guides explored PrEP knowledge, HIV acquisition risk, gender identity, motivation for PrEP uptake and adherence and PrEP-dispensing venue preferences. Braun and Clarke thematic analysis was applied. Four themes emerged: limited preparedness of HCPs to provide PrEP to TW and MSM, varied motivation for PrEP uptake and persistence among end users, lack of recognition of TW by HCPs and suggestions for PrEP programming improvement from all stakeholders. Providers' reluctance to prescribe PrEP to TW and distrust of TW towards providers calls for interventions to improve the capacity of service environments and staff HIV preventive care. Alternative locations for PrEP provision, including community-based sites, may be developed with TW/MSM leaders.

Abstract
BACKGROUND Despite the development of a safe and efficacious hepatitis B vaccine in 1982, the hepatitis B virus (HBV) remains a public health burden in sub-Saharan Africa. Due to shared risk factors for virus acquisition, men who have sex with men (MSM) and transgender women (TGW) living with HIV are at increased risk of HBV. We estimated the prevalence of HBV and associated factors for MSM and TGW living with or without HIV in Nigeria. METHODS Since March 2013, TRUST/RV368 has recruited MSM and TGW in Abuja and Lagos, Nigeria using respondent driven sampling. Participants with HIV diagnosis, enrollment as of June 2015, and available plasma were selected for a cross-sectional study and retrospectively tested for hepatitis B surface antigen and HBV DNA. Logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for factors associated with prevalent HBV infection. RESULTS A total of 717 MSM and TGW had a median age of 25 years (interquartile range [IQR]: 21-27), 5% self-reported HBV vaccination, 61% were living with HIV, 10% had prevalent HBV infection and 6% were HIV-HBV co-infected. HIV mono-infected as compared to HIV-HBV co-infected had a higher median CD4 T cell count [425 (IQR: 284-541) vs. 345 (IQR: 164-363) cells/mm3, p = 0.03] and a lower median HIV RNA viral load [4.2 (IQR: 2.3-4.9) vs. 4.7 (IQR: 3.9-5.4) log10copies/mL, p < 0.01]. The only factor independently associated with HBV was self-report of condomless sex at last anal intercourse (OR: 2.2, 95% CI: 1.3, 3.6). HIV infection was not independently associated with HBV (OR: 1.0, 95% CI: 0.7-1.6). CONCLUSION HBV prevalence was moderately high but did not differ by HIV in this cohort of MSM and TGW. Recent condomless sex was associated with elevated HBV risk, reinforcing the need to increase communication and education on condom use among key populations in Nigeria. Evaluating use of concurrent HIV antiretroviral therapy with anti-HBV activity may confirm the attenuated HBV prevalence for those living with HIV.

Costs of implementing community-based intervention for HIV testing in sub-Saharan Africa: a systematic review. Implement Sci Commun 2021; 2:73. [PMID: 34225820 PMCID: PMC8259076 DOI: 10.1186/s43058-021-00177-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2020] [Accepted: 06/22/2021] [Indexed: 12/20/2022] Open
Abstract
Background Community-based interventions (CBIs) are interventions aimed at improving the well-being of people in a community. CBIs for HIV testing seek to increase the availability of testing services to populations that have been identified as at high risk by reaching them in homes, schools, or community centers. However, evidence for a detailed cost analysis of these community-based interventions in sub-Saharan Africa (SSA) is limited. We conducted a systematic review of the cost analysis of HIV testing interventions in SSA. Methods Keyword search was conducted on SCOPUS, CINAHL, MEDLINE, PsycINFO, Web of Science, and Global Health databases. Three categories of key terms used were cost (implementation cost OR cost-effectiveness OR cost analysis OR cost-benefit OR marginal cost), intervention (HIV testing), and region (sub-Saharan Africa OR sub-Saharan Africa OR SSA). CBI studies were included if they primarily focused on HIV testing, was implemented in SSA, and used micro-costing or ingredients approach. Results We identified 1533 citations. After screening, ten studies were included in the review: five from East Africa and five from Southern Africa. Two studies conducted cost-effectiveness analysis, and one study was a cost-utility analysis. The remainder seven studies were cost analyses. Four intervention types were identified: HIV self-testing (HIVST), home-based, mobile, and Provider Initiated Testing and Counseling. Commonly costed resources included personnel (n = 9), materials and equipment (n = 6), and training (n = 5). Cost outcomes reported included total intervention cost (n = 9), cost per HIV test (n = 9), cost per diagnosis (n = 5), and cost per linkage to care (n = 3). Overall, interventions were implemented at a higher cost than controls, with the largest cost difference with HIVST compared to facility-based testing. Conclusion To better inform policy, there is an urgent need to evaluate the costs associated with implementing CBIs in SSA. It is important for cost reports to be detailed, uniform, and informed by economic evaluation guidelines. This approach minimizes biases that may lead decision-makers to underestimate the resources required to scale up, sustain, or reproduce successful interventions in other settings. In an evolving field of implementation research, this review contributes to current resources on implementation cost studies.

Abstract
Gay and bisexual men (GBM) who report engagement in transactional sex are at increased risk for HIV acquisition. The current study aimed to assess the prevalence of transactional sex and its association with demographic characteristics, social marginalization, HIV sexual risk behaviors, psychosocial health problems, and access to healthcare services among a multi-site sample of GBM in Nigeria. Bivariate and multivariable logistic regression were used to examine factors associated with engagement in transactional sex in the previous 3 months. More than a third (39.6%) of the participants reported engagement in transactional sex in the previous 3 months. In the multivariable model, factors associated with engagement in transactional sex included: reporting a monthly income of 30,000 Naira [adjusted odds ratio (aOR) 1.98; 95% CI: 1.12 to 3.35], compared to 30,000 or more Naira monthly income, reporting 4 or more receptive anal sex acts in the previous 30 days (aOR 2.45; 95% CI: 1.31 to 4.57) compared to reporting none, and having depressive symptoms (aOR 1.82; 95% CI: 1.06 to 3.14). There is an urgent need for interventions that address the economic disenfranchisement and psychosocial problems experienced by GBM in Nigeria, which has implications for sexual health.

HIV pre-exposure prophylaxis for men who have sex with men in west Africa: a multicountry demonstration study. Lancet HIV 2021; 8:e420-e428. [PMID: 34048794 DOI: 10.1016/s2352-3018(21)00005-9] [Citation(s) in RCA: 31] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2020] [Revised: 01/12/2021] [Accepted: 01/15/2021] [Indexed: 11/22/2022]
Abstract
BACKGROUND HIV pre-exposure prophylaxis (PrEP) data in men who have sex with men (MSM) in west Africa are essential to guide its large-scale implementation. We assessed the uptake of event-driven and daily PrEP, HIV incidence, and changes over time in sexual behaviours and prevalence of bacterial sexually transmitted infections (STIs) in MSM in Burkina Faso, Côte d'Ivoire, Mali, and Togo. METHODS We did a prospective cohort study from Nov 20, 2017, to April 14, 2020, in four community-based clinics in Abidjan (Côte d'Ivoire), Bamako (Mali), Lomé (Togo), and Ouagadougou (Burkina Faso). Participants were MSM aged 18 years or older at substantial risk of HIV infection. Participants could choose between event-driven (2+1+1 dosing) and daily oral PrEP (tenofovir disoproxil fumarate 300 mg plus emtricitabine 200 mg), switch regimen, and discontinue or restart PrEP. We compared HIV incidence in this study with that of the same cohort before the availability of PrEP (CohMSM). Statistical analysis included the Kaplan-Meier method and mixed-effects regression models. This study is registered with ClinicalTrials.gov, NCT03459157. FINDINGS We followed up 598 participants for a total of 743·6 person-years. At enrolment, 445 (74%) of 598 participants chose event-driven PrEP and 153 (26%) of 598 chose daily PrEP. 60 (13%) of 445 and 65 (42%) of 153 participants switched PrEP regimen at least once (p<0·0001). 159 participants (27%) were lost to follow-up. Overall HIV incidence was 2·3 per 100 person-years (95% CI 1·3-3·7; adjusted incidence rate ratio 0·21, 95% CI 0·12-0·36 compared with CohMSM). Adherence was optimal in 802 (41%) of 1946 measures with event-driven PrEP and in 394 (71%) of 554 measures with daily PrEP (p<0·0001). Coverage of sex acts with PrEP only and PrEP and condom decreased during follow-up (p=0·039 if PrEP only; p=0·0025 if PrEP and condom). The frequency of condomless anal sex remained stable (p=0·96). The number of male sexual partners (p<0·0001) and number of sex acts with casual male partners (p=0·0014 for 1-4 sex acts in previous 4 weeks; p=0·030 for ≥5 sex acts) decreased. The prevalence of gonorrhoea, chlamydia, and syphilis remained stable. INTERPRETATION PrEP availability helped prevent HIV infection and did not lead to an increase in risky sexual behaviours or other STIs. PrEP should be urgently implemented in west Africa. Retention in care and PrEP adherence require special attention to ensure PrEP reaches its full prevention potential. FUNDING ANRS and Expertise France.

Abstract
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. Trial registration ClinicalTrials.gov, number NCT02626286 (December 10, 2015).

Abstract
Background Human immunodeficiency virus (HIV) partner notification services (HPN), peer mobilization with HIV self-testing, and acute and early HIV infection (AEHI) screening among gay, bisexual, and other men who have sex with men (GBMSM) and transgender women (TGW) were assessed for acceptability, feasibility, and linkage to antiretroviral therapy (ART) and preexposure prophylaxis (PrEP) services. Methods Between April and August 2019, peer mobilizers mobilized clients by offering HIV oral self-tests and immediate clinic referral for clients with AEHI symptoms. Mobilized participants received clinic-based rapid antibody testing and point-of-care HIV RNA testing. Newly diagnosed participants including those derived from HIV testing services were offered immediate ART and HPN. Partners were recruited through HPN. Results Of 772 mobilized clients, 452 (58.5%) enrolled in the study as mobilized participants. Of these, 16 (3.5%) were HIV newly diagnosed, including 2 (0.4%) with AEHI. All but 2 (14/16 [87.5%]) initiated ART. Thirty-five GBMSM and TGW were offered HPN and 27 (77.1%) accepted it. Provider referral identified a higher proportion of partners tested (39/64 [60.9%] vs 5/14 [35.7%]) and partners with HIV (27/39 [69.2%] vs 2/5 [40.0%]) than index referral. Of 44 enrolled partners, 10 (22.7%) were newly diagnosed, including 3 (6.8%) with AEHI. All 10 (100%) initiated ART. PrEP was initiated among 24.0% (103/429) mobilized participants and 28.6% (4/14) partners without HIV. Conclusions HPN, combined with a peer mobilization-led self-testing strategy and AEHI screening for GBMSM and TGW, appears to be acceptable and feasible. These strategies, especially HPN provider referral, effectively identified undiagnosed HIV infections and linked individuals to ART and PrEP services.

Abstract
BACKGROUND Key populations (KP) including men who have sex with men (MSM), female sex workers (FSW), and their clients are disproportionately affected by HIV in Sub-Saharan Africa. We estimated the evolving impact of past interventions and contribution of unmet HIV prevention/treatment needs of key populations and lower-risk groups to HIV transmission. SETTING Yaoundé, Cameroon. METHODS We parametrized and fitted a deterministic HIV transmission model to Yaoundé-specific demographic, behavioral, HIV, and intervention coverage data in a Bayesian framework. We estimated the fraction of incident HIV infections averted by condoms and antiretroviral therapy (ART) and the fraction of all infections over 10-year periods directly and indirectly attributable to sex within and between each risk group. RESULTS Condom use and ART together may have averted 43% (95% uncertainty interval: 31-54) of incident infections over 1980-2018 and 72% (66-79) over 2009-2018. Most onward transmissions over 2009-2018 stemmed from sex between lower-risk individuals [47% (32-61)], clients [37% (23-51)], and MSM [35% (20-54)] with all their partners. The contribution of commercial sex decreased from 25% (8-49) over 1989-1998 to 8% (3-22) over 2009-2018, due to higher intervention coverage among FSW. CONCLUSION Condom use and recent ART scale-up mitigated the HIV epidemic in Yaoundé and changed the contribution of different partnerships to onward transmission over time. Findings highlight the importance of prioritizing HIV prevention and treatment for MSM and clients of FSW whose unmet needs now contribute most to onward transmission, while maintaining services that successfully reduced transmissions in the context of commercial sex.

Abstract
BACKGROUND Effective condom use is a critical intervention to limit the spread of HIV and other sexually transmitted infections, particularly among individuals in high-risk networks who practice anal sex. We characterized condom failures in cisgender men who have sex with men and transgender women in Nigeria. SETTING The TRUST/RV368 cohort provided condoms, compatible lubricants, and safer sex education to men who have sex with men and transgender women at community-engaged health centers in Abuja and Lagos, Nigeria. METHODS Participants completed structured interview questions about condom usage and failure every 3-6 months. Robust Poisson regression models with generalized estimating equations were used to estimate relative risks and 95% confidence intervals for prespecified factors potentially associated with condom failure in the previous month. RESULTS From September 2013 to September 2019, 2221 of 2737 participants (81.1%) reported condom use for anal sex with a male partner in the last month, and 305 (13.7%) reported condom failure during this time. Multivariate analyses demonstrated an increased risk of condom failure at postenrollment visits, as well as in participants who reported frequent Internet use, 2 or more casual sexual partners, and 2-4 main sexual partners. Those who cohabited with a woman had reduced risk. CONCLUSIONS Condom failure was common in this population despite freely available condoms, compatible lubrication, and education. Increased risk of condom failure over time could reflect message fatigue a ceiling for effective condom use, or new uptake of condoms by inexperienced users.

HIV incidence in a multinational cohort of men and transgender women who have sex with men in sub-Saharan Africa: Findings from HPTN 075. PLoS One 2021; 16:e0247195. [PMID: 33630925 PMCID: PMC7906338 DOI: 10.1371/journal.pone.0247195] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2020] [Accepted: 02/02/2021] [Indexed: 11/19/2022] Open
Abstract
Few studies have assessed HIV incidence in men who have sex with men (MSM) and transgender women (TGW) in sub-Saharan Africa (SSA). We assessed HIV incidence and its correlates among MSM and TGW in SSA enrolled in the prospective, multi-country HIV Prevention Trials Network (HPTN) 075 study, conducted from 2015 to 2017. Participants were enrolled at four sites in SSA (Kisumu, Kenya; Blantyre, Malawi; Cape Town and Soweto, South Africa). Eligible participants reported male sex assignment at birth, were 18 to 44 years of age, and had engaged in anal intercourse with a man in the preceding three months. Participation involved five study visits over 12 months. Visits included behavioral assessments and testing for HIV and sexually transmitted infections. Twenty-one of 329 persons acquired HIV during the study [incidence rate: 6.96/100 person-years (PY) (95% CI: 4.3, 10.6)]. Among TGW, HIV incidence was estimated to be 8.4/100 PY (95% CI: 2.3, 21.5). Four participants were found to have acute HIV infection at their first HIV-positive visit. HIV incidence varied among the four study sites, ranging from 1.3/100 PY to 14.4/100 PY. In multivariate longitudinal analysis, factors significantly associated with HIV acquisition were engagement in unprotected receptive anal intercourse [adjusted hazard ratio (AHR) 5.8, 95% confidence interval (CI): 2.4, 14.4] and incident rectal gonorrhea and/or chlamydia (AHR: 2.7, 95% CI: 1.1, 6.8). The higher HIV incidence in Cape Town compared to Blantyre could be explained by the higher prevalence of several risk factors for HIV infection among participants in Cape Town. Annual HIV incidence observed in this study is substantially higher than reported HIV incidence in the general populations in the respective countries and among MSM in the United States. Intensification of HIV prevention efforts for MSM and TGW in SSA is urgently needed.

Abstract
The Walter Reed Army Institute of Research (WRAIR) supports more than 350,000 people on lifesaving HIV treatment in Kenya, Nigeria, Tanzania, and Uganda through funding from the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR). Here, we review and synthesize the range of impacts WRAIR’s implementation science portfolio has had on PEPFAR service delivery for military and civilian populations since 2003. We also explore how investments in implementation science create institutional synergies within the U.S. Department of Defense, contributing to broad global health engagements and improving health outcomes for populations served. Finally, we discuss WRAIR’s contributions to PEPFAR priorities through use of data to drive and improve programming in real time in the era of HIV epidemic control and public health messaging that includes prevention, the 95-95-95 goals, and comorbidities.

Field evaluation of HIV-1 viral load monitoring in adults and children receiving antiretroviral treatment in Nigeria by dried blood spot testing with RealTime HIV-1 on m2000. J Clin Virol 2021; 135:104694. [PMID: 33476928 DOI: 10.1016/j.jcv.2020.104694] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2020] [Revised: 11/11/2020] [Accepted: 11/15/2020] [Indexed: 10/22/2022]
Abstract
In resource-limited settings, use of dried blood spots (DBS) could be a pragmatic alternative to plasma for VL monitoring in people living with HIV (PLWH). We compared results from DBS to standard plasma VL testing under field conditions in patients receiving antiretroviral therapy (ART). DBS cards were prepared from venous blood (V-DBS), finger-pricks using micro-capillary tubes (M-DBS), and direct spotting (D-DBS). DBS and matched EDTA plasma were tested on the Abbott m2000 platform using the appropriate RealTime HIV-1 quantitative CE protocol. Matched plasma samples were also tested on the Roche COBAS Ampliprep/COBAS TaqMan version 2.0. Diagnostic accuracy indicators (sensitivity, specificity, misclassification rate, and kappa coefficient) for viral failure (VF) based on different VL threshold levels and agreement of absolute VL were calculated. A total of 669 participants provided 2676 samples. V-DBS had a peak sensitivity for VF of 89.1 % [95 % CI: 85.5-92.7] at the 1000 copies/mL threshold and a peak specificity of 97.4 % [95 % CI: 95.9-99.0] at the 5000 copies/mL threshold. The lowest proportion of upward misclassification (patients classified with VF who actually had viral suppression) for V-DBS was 3.1 % [95 % CI: 1.4-4.8] at the 5000 copies/mL threshold, whereas the lowest proportion of downward misclassification (patients classified as undetectable who actually had VF) was 10.9 % [95 % CI: 7.2-14.5] at the 1000 copies/mL threshold. Abbott RealTime HIV-1 VL results from all 3 DBS types for adults and children showed strong correlation with the gold standard plasma-based assay. DBS could be useful for monitoring VL in resource limited settings such as Nigeria.

Abstract
BACKGROUND Across sub-Saharan Africa, men who have sex with men (MSM) and transgender women (TGW) have disproportionately poor HIV treatment outcomes. Stigma and criminalization create barriers to health-care engagement and adherence to antiretroviral therapy (ART), potentially promoting the development of HIV drug resistance (HIVDR). We evaluated transmitted, pre-treatment and acquired HIVDR among MSM and TGW in Lagos and Abuja, Nigeria. METHODS Adults with HIV RNA ≥1,000 copies/ml in the TRUST/RV368 cohort, including incident cases diagnosed via 3-monthly screening, underwent HIVDR testing using the Sanger sequencing method. Major mutations conferring resistance to nucleoside reverse transcriptase inhibitors (NRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs) and protease inhibitors (PIs) were identified from the 2017 IAS-USA list. World Health Organization surveillance drug resistance mutations (SDRMs) were identified in ART-naive participants. RESULTS From March 2013 to June 2017, 415 participants with median age 24 (interquartile range [IQR] 21-27) years, CD4+ T-cell count 370 (IQR 272-502) cells/mm3, and HIV RNA 4.73 (IQR 4.26-5.15) log10 copies/ml underwent HIVDR testing. SDRMs were observed in 36 of 373 ART-naive participants (9.7%, 95% confidence interval [95% CI 6.8, 13.1%]), including 8 of 39 incident cases (20.5%, [95% CI] 9.3, 36.5%). Among 42 ART-experienced participants, NNRTI resistance was detected in 18 (42.9%, 95% CI 27.7, 59.0%) and NRTI resistance in 10 (23.8%, 95% CI 12.0, 39.4%). No PI resistance was detected. CONCLUSIONS The high prevalence of transmitted and acquired drug resistance among Nigerian MSM and TGW living with HIV suggests the need for programmatic solutions to improve uninterrupted access to ART and timely switch to second-line regimens in cases of viral failure.

Abstract
INTRODUCTION Men who have sex with men (MSM), and transgender women (TGW), face specific obstacles to retention in care, particularly in settings with stigmatization such as sub-Saharan Africa. We evaluated the impacts of HIV status and other factors on loss-to-follow-up (LTFU) and visit adherence among MSM and TGW in Abuja and Lagos, Nigeria. METHODS TRUST/RV368 is an open cohort that provides comprehensive and integrated prevention and treatment services for HIV and sexually transmitted infections (STIs) at community venues supportive of sexual and gender minorities. Recruitment began in March 2013 and participants were followed every three months for up to 18 months. LTFU was defined as not presenting for an expected visit in the past 180 days. Visit adherence was calculated as a rate of completed visits adjusted by the number of three-month intervals elapsed since enrolment. HIV and other factors predictive of LTFU and visit adherence were evaluated using Cox proportional hazards and Poisson regression models, respectively. RESULTS A total of 1447 participants who completed enrolment evaluations over two visits as of November 2018 were included in these analyses. Their median age was 24 years (interquartile range [IQR]: 21 to 28) and 53% (n = 766) were living with HIV. LTFU occurred in 56% (n = 808) and visit adherence was 0.62 (95% confidence interval: 0.61 to 0.64) visits per three-month interval. Participants at risk and living with HIV had median follow-up times of 12 months (IQR: 6 to 22), and 21 months (IQR: 12 to 30), respectively (p < 0.01). After controlling for other factors, LTFU was less common among participants living with HIV or other STIs and more common among those who did not own a cell phone, sold sex and had never undergone HIV testing prior to enrolment. These factors had parallel associations with visit adherence. CONCLUSIONS Retention was suboptimal in Nigerian clinics designed to serve MSM and TGW. Particularly high LTFU and low visit adherence among participants at risk for HIV could complicate deployment of HIV prevention interventions. Marketing the benefits of testing, improving access to cell phones and nurturing more trust with clients may improve retention among marginalized communities in Nigeria.

Abstract
INTRODUCTION Screening for acute and early HIV infections (AEHI) among men who have sex with men (MSM) remains uncommon in sub-Saharan Africa (SSA). Yet, undiagnosed AEHI among MSM and subsequent failure to link to care are important drivers of the HIV epidemic. We conducted a systematic review and meta-analysis of AEHI yield among MSM mobilized for AEHI testing; and assessed which risk factors and/or symptoms could increase AEHI yield in MSM. METHODS We systematically searched four databases from their inception through May 2020 for studies reporting strategies of mobilizing MSM for testing and their AEHI yield, or risk and/or symptom scores targeting AEHI screening. AEHI yield was defined as the proportion of AEHI cases among the total number of visits. Study estimates for AEHI yield were pooled using random effects models. Predictive ability of risk and/or symptom scores was expressed as the area under the receiver operator curve (AUC). RESULTS Twenty-two studies were identified and included a variety of mobilization strategies (eight studies) and risk and/or symptom scores (fourteen studies). The overall pooled AEHI yield was 6.3% (95% CI, 2.1 to 12.4; I2 = 94.9%; five studies); yield varied between studies using targeted strategies (11.1%; 95% CI, 5.9 to 17.6; I2 = 83.8%; three studies) versus universal testing (1.6%; 95% CI, 0.8 to 2.4; two studies). The AUC of risk and/or symptom scores ranged from 0.69 to 0.89 in development study samples, and from 0.51 to 0.88 in validation study samples. AUC was the highest for scores including symptoms, such as diarrhoea, fever and fatigue. Key risk score variables were age, number of sexual partners, condomless receptive anal intercourse, sexual intercourse with a person living with HIV, a sexually transmitted infection, and illicit drug use. No studies were identified that assessed AEHI yield among MSM in SSA and risk and/or symptom scores developed among MSM in SSA lacked validation. CONCLUSIONS Strategies mobilizing MSM for targeted AEHI testing resulted in substantially higher AEHI yields than universal AEHI testing. Targeted AEHI testing may be optimized using risk and/or symptom scores, especially if scores include symptoms. Studies assessing AEHI yield and validation of risk and/or symptom scores among MSM in SSA are urgently needed.

Wahome EW, Graham SM, Thiong’o AN, Mohamed K, Oduor T, Gichuru E, Mwambi J, van der Elst EM, Sanders EJ. Risk factors for loss to follow-up among at-risk HIV negative men who have sex with men participating in a research cohort with access to pre-exposure prophylaxis in coastal Kenya. J Int AIDS Soc 2020; 23 Suppl 6:e25593. [PMID: 33000889 PMCID: PMC7527770 DOI: 10.1002/jia2.25593] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2020] [Revised: 07/07/2020] [Accepted: 07/15/2020] [Indexed: 12/20/2022] Open
Abstract
INTRODUCTION Retention in preventive care among at-risk men who have sex with men (MSM) is critical for successful prevention of HIV acquisition in Africa. We assessed loss to follow-up (LTFU) rates and factors associated with LTFU in an HIV vaccine feasibility cohort study following MSM with access to pre-exposure prophylaxis (PrEP) in coastal Kenya. METHODS Between June 2017 and June 2019, MSM cohort participants attending a research clinic 20 km north of Mombasa were offered daily PrEP and followed monthly for risk assessment, risk reduction counselling and HIV testing. Participants were defined as LTFU if they were late by >90 days for their scheduled appointment. Participants who acquired HIV were censored at diagnosis. Cox proportional hazards models were used to estimate adjusted Hazard Ratio (aHR) of risk factors for LTFU. RESULTS AND DISCUSSION A total of 179 participants with a median age of 25.0 years (interquartile range [IQR]: 23.0 to 30.0) contributed a median follow-up time of 21.2 months (IQR: 6.5 to 22.1). Of these, 143 (79.9%) participants started PrEP and 76 (42.5%) MSM were LTFU, for an incidence rate of 33.7 (95% confidence interval [CI], 26.9 to 42.2) per 100 person-years. Disordered alcohol use (aHR: 2.3, 95% CI, 1.5 to 3.7), residence outside the immediate clinic catchment area (aHR: 2.5, 95% CI, 1.3 to 4.6 for Mombasa Island; aHR: 1.8, 95% CI, 1.0 to 3.3 for south coast), tertiary education level or higher (aHR: 2.3, 95% CI, 1.1 to 4.8) and less lead-in time in the cohort prior to 19 June 2017 (aHR: 3.1, 95% CI, 1.8 to 5.6 for zero to three months; aHR: 2.4, 95% CI, 1.2 to 4.7 for four to six months) were independent predictors of LTFU. PrEP use did not differ by LTFU status (HR: 1.0, 95% CI, 0.6 to 1.5). Psychosocial support for men reporting disordered alcohol use, strengthened engagement of recently enrolled participants and focusing recruitment on areas close to the research clinic may improve retention in HIV prevention studies involving MSM in coastal Kenya. CONCLUSIONS About one in three participants became LTFU after one year of follow-up, irrespective of PrEP use. Research preparedness involving MSM should be strengthened for HIV prevention intervention evaluations in coastal Kenya.

Association of age with healthcare needs and engagement among Nigerian men who have sex with men and transgender women: cross-sectional and longitudinal analyses from an observational cohort. J Int AIDS Soc 2020; 23 Suppl 6:e25599. [PMID: 33000907 PMCID: PMC7527771 DOI: 10.1002/jia2.25599] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2020] [Revised: 07/10/2020] [Accepted: 07/20/2020] [Indexed: 01/02/2023] Open
Abstract
INTRODUCTION Young men who have sex with men (MSM) and transgender women (TGW) face stigmas that hinder access to healthcare. The aim of the study was to understand age-related determinants of healthcare needs and engagement among MSM and TGW. METHODS The TRUST/RV368 cohort provides integrated prevention and treatment services for HIV and other sexually transmitted infections (STIs) tailored to the needs of sexual and gender minorities. MSM and TGW aged ≥16 years in Abuja and ≥18 years Lagos, Nigeria, completed standardized behavioural questionnaires and were tested for HIV, Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) every three months for up to 18 months. Logistic regression was used to estimate adjusted odds ratios (aORs) for associations of age and other factors with outcomes of interest upon enrolment, including HIV care continuum steps - HIV testing, ART initiation and viral suppression <1000 copies/mL. Cox proportional hazards models were used to calculate adjusted hazard ratios (aHRs) for associations with incident infections. RESULTS Between March 2013 and February 2019, 2123 participants were enrolled with median age 23 (interquartile range 21 to 27) years. Of 1745 tested, 865 (49.6%) were living with HIV. HIV incidence was 11.6/100 person-years [PY], including 23.1/100PY (95% CI 15.5 to 33.1) among participants aged 16 to 19 years and 23.8/100 PY (95% CI 13.6 to 39.1) among TGW. Compared to participants aged ≥25 years, those aged 16 to 19 years had decreased odds of prior HIV testing (aOR 0.40 [95% CI 0.11 to 0.92]), disclosing same-sex sexual practices to healthcare workers (aOR 0.53 [95% CI 0.36 to 0.77]) and receiving HIV prevention information (aOR 0.60 [95% CI 0.41 to 0.87]). They had increased odds of avoiding healthcare (aOR 1.94 [95% CI 1.3 to 2.83]) and engaging in transactional sex (aOR 2.76 [95% CI 1.92 to 3.71]). Age 16 to 19 years was independently associated with increased incidence of HIV (aHR 4.09 [95% CI 2.33 to 7.49]), NG (aHR 3.91 [95% CI 1.90 to 8.11]) and CT (aHR 2.74 [95% CI 1.48 to 5.81]). CONCLUSIONS Young MSM and TGW demonstrated decreased healthcare engagement and higher incidence of HIV and other STIs as compared to older participants in this Nigerian cohort. Interventions to address unique obstacles to healthcare engagement by adolescents and young adults are needed to curb the spread of HIV and other STIs among MSM and TGW in Nigeria.

Enrolment characteristics associated with retention among HIV negative Kenyan gay, bisexual and other men who have sex with men enrolled in the Anza Mapema cohort study. J Int AIDS Soc 2020; 23 Suppl 6:e25598. [PMID: 33000884 PMCID: PMC7527767 DOI: 10.1002/jia2.25598] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2020] [Revised: 07/10/2020] [Accepted: 07/20/2020] [Indexed: 12/18/2022] Open
Abstract
INTRODUCTION Most gay, bisexual and other men who have sex with men (GBMSM) live in rights-constrained environments making retaining them in research to be as hard as recruiting them. To evaluate Anza Mapema, an HIV risk-reduction programme in Kisumu, Kenya, we examined the enrolment sociodemographic, behavioural, psychosocial and clinical factors associated with missing two or more follow-up visits for GBMSM participating in Anza Mapema. METHODS Between August 2015 and November 2017, GBMSM were enrolled and followed in a prospective cohort study with quarterly visits over 12 months. At enrolment, men were tested for HIV and sexually transmitted infections and completed questionnaires via audio computer-assisted self-interview. Because the Kenya Ministry of Health recommends HIV testing every three to six months for GBMSM, the retention outcome in this cross sectional analysis was defined as missing two consecutive follow-up visits (vs. not missing two or more consecutive visits). Multivariable logistic regression estimated the adjusted odds ratios (aOR) and 95% confidence intervals (CI) for the associations of the enrolment characteristics with the binary outcome of retention. RESULTS AND DISCUSSION Among 609 enrolled HIV-negative GBMSM, the median age was 23 years (interquartile range, 21 to 28 years), 19.0% had completed ≤8 years of education and 4.1% had resided in the study area <1 year at enrolment. After enrolment, 19.7% missed two consecutive follow-up visits. In the final multivariable model, the odds of missing two consecutive follow-up visits were higher for men who: resided in the study area <1 year at enrolment (aOR, 4.14; 95% CI: 1.77 to 9.68), were not living with a male sexual partner (aOR, 1.59; 95% CI: 1.01 to 2.50), and engaged in transactional sex during the last three months (aOR, 1.70; 95% CI: 1.08 to 2.67). CONCLUSIONS One in five men missed two consecutive follow-up visits during this HIV prevention study despite intensive retention efforts and compensation for travel and participation. Participants with recent community arrival may require special support to optimize their retention in HIV prevention activities. Live-in partners of participants may be enlisted to support greater engagement in prevention programmes, and men who engage in transactional sex will need enhanced counselling and support to stay in longitudinal studies.

Oral sex practices among men who have sex with men and transgender women at risk for and living with HIV in Nigeria. PLoS One 2020; 15:e0238745. [PMID: 32886722 PMCID: PMC7473579 DOI: 10.1371/journal.pone.0238745] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2020] [Accepted: 08/21/2020] [Indexed: 12/15/2022] Open
Abstract
Background Men who have sex with men (MSM) and transgender women (TGW) are at risk for sexually transmitted infections (STIs), including those of the oropharynx. We estimated the prevalence and factors associated with oral sex practices and characterized oropharyngeal STIs among a cohort of MSM and TGW in Nigeria. Methods From 2013 to 2018, TRUST/RV368 recruited MSM and TGW into HIV/STI diagnosis and treatment at community-based clinics in Nigeria. Participants who completed HIV testing and oral sex questions at enrollment were selected. Cross-sectional analyses with bivariate and multivariable logistic regression models estimated odds ratios (ORs) and 95% confidence intervals (CIs). Oropharyngeal swab testing for Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) began in 2014 and for those with diagnostic results at enrollment, the unadjusted association of oral sex practices with oropharyngeal STIs was conducted. Results A total of 1342 participants had a median age of 25 years (interquartile range: 22–29), 58% were living with HIV, and 69% reported oral sex practices. Factors associated with increased odds of engaging in oral sex included living with HIV (adjusted [a]OR: 1.4, 95% CI: 1.1–1.8), self-identifying as a woman (aOR:1.8, 95% CI: 1.1–2.8), mobile phone ownership (aOR:2.3, 95% CI: 1.3–3.9), receptive anal sex (aOR:1.7, 95% CI:1.3–2.3) and multiple male sexual partners (2 to 4 vs. ≤1, aOR:1.5, 95% CI: 1.0–2.2; 5+ vs ≤1, aOR:2.9, 95% CI:1.9–4.3). Oropharyngeal STI prevalence was 7% (52/752) and higher among those who engaged in oral sex compared to those who did not (unadjusted OR: 2.5, 95% CI:1.2–5.3). Conclusions Oral sex was common and associated with an increased odds of oropharyngeal STIs among MSM and TGW from Nigeria. In the absence of screening and treatment guidelines, condoms continue to be the mainstay for oral STI prevention. A pre-exposure prophylaxis for bacterial STIs would complement current prevention strategies to curb transmission.

Seizing opportunities for intervention: Changing HIV-related knowledge among men who have sex with men and transgender women attending trusted community centers in Nigeria. PLoS One 2020; 15:e0229533. [PMID: 32119701 PMCID: PMC7051043 DOI: 10.1371/journal.pone.0229533] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2019] [Accepted: 02/07/2020] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND Knowledge of HIV risk factors and reduction strategies is essential for prevention in key populations such as men who have sex with men (MSM) and transgender women (TGW). We evaluated factors associated with HIV-related knowledge among MSM and TGW and the impact of engagement in care at trusted community health centers in Nigeria. METHODS The TRUST/RV368 cohort recruited MSM and TGW in Lagos and Abuja, Nigeria via respondent driven sampling. During study visits every three months, participants underwent structured interviews to collect behavioral data, received HIV education, and were provided free condoms and condom compatible lubricants. Five HIV-related knowledge questions were asked at enrollment and repeated after 9 and 15 months. The mean number of correct responses was calculated for each visit with 95% confidence intervals (CIs). Multivariable Poisson regression was used to calculate adjusted risk ratios and CIs for factors associated with answering more knowledge questions correctly. RESULTS From March 2013 to April 2018, 2122 persons assigned male sex at birth were enrolled, including 234 TGW (11.2%). The mean number of correct responses at enrollment was 2.36 (95% CI: 2.31-2.41) and increased to 2.95 (95% CI: 2.86-3.04) and 3.06 (95% CI: 2.97-3.16) after 9 and 15 months in the study, respectively. Among 534 participants who completed all three HIV-related knowledge assessments, mean number of correct responses rose from 2.70 (95% CI: 2.60-2.80) to 3.02 (95% CI: 2.93-3.13) and then 3.06 (95% CI: 2.96-3.16). Factors associated with increased overall HIV-related knowledge included longer duration of study participation, HIV seropositivity, higher education level, and more frequent internet use. CONCLUSIONS There was suboptimal HIV-related knowledge among Nigerian MSM and TGW at that improved modestly with engagement in care. These data demonstrate unmet HIV education needs among Nigerian MSM and TGW and provide insights into modalities that could be used to address these needs.

Abstract
BACKGROUND The HIV epidemic continues to grow among MSM in countries across sub-Saharan Africa including Nigeria. To inform prevention efforts, we used a phylogenetic cluster method to characterize HIV genetic clusters and factors associated with cluster formation among MSM living with HIV in Nigeria. METHODS We analyzed HIV-1 pol sequences from 417 MSM living with HIV enrolled in the TRUST/RV368 cohort between 2013 and 2017 in Abuja and Lagos, Nigeria. A genetically linked cluster was defined among participants whose sequences had pairwise genetic distance of 1.5% or less. Binary and multinomial logistic regressions were used to estimate adjusted odds ratios (AORs) and 95% confidence intervals (CIs) for factors associated with HIV genetic cluster membership and size. RESULTS Among 417 MSM living with HIV, 153 (36.7%) were genetically linked. Participants with higher viral load (AOR = 1.72 95% CI: 1.04-2.86), no female partners (AOR = 3.66; 95% CI: 1.97-6.08), and self-identified as male sex (compared with self-identified as bigender) (AOR = 3.42; 95% CI: 1.08-10.78) had higher odds of being in a genetic cluster. Compared with unlinked participants, MSM who had high school education (AOR = 23.84; 95% CI: 2.66-213.49), were employed (AOR = 3.41; 95% CI: 1.89-10.70), had bacterial sexually transmitted infections (AOR = 3.98; 95% CI: 0.89-17.22) and were not taking antiretroviral therapy (AOR = 6.61; 95% CI: 2.25-19.37) had higher odds of being in a large cluster (size > 4). CONCLUSION Comprehensive HIV prevention packages should include behavioral and biological components, including early diagnosis and treatment of both HIV and bacterial sexually transmitted infections to optimally reduce the risk of HIV transmission and acquisition.

Abstract
Strategies for HIV prevention among infants, children, and adolescents have evolved significantly over the past 20 years. These include the global scale-up of simplified multidrug HIV regimens for pregnant women, leading to impressive reductions in new child HIV infections. However, significant gaps remain, especially in high HIV-burden sub-Saharan African countries. For example, many pregnant women living with HIV (WLHIV) are unable to access and sustain HIV testing and treatment partly due to low agency and harmful gender norms. Among pregnant WLHIV, adolescent girls face an additional layer of societal and health-system barriers in accessing care for themselves and their exposed infants. Legal and structural barriers limit access to HIV prevention-related sexual and reproductive health services among high-risk adolescents, including girls and young men who have sex with men. Key ethical issues underlying HIV prevention gaps for infants, children, and adolescents prevail. This narrative review explores these issues and highlights counter-measures for programming and policy, including gender empowerment, improving access to and appropriateness of critical health services, rights-based policy and legislation, closing research gaps, and considering the values and preferences of young people for HIV prevention and treatment services.

Syphilis associated with recreational drug use, depression and high-risk sexual behaviour in men who have sex with men: a case-control study in China. Sex Transm Infect 2019; 95:267-272. [PMID: 30842346 PMCID: PMC11093516 DOI: 10.1136/sextrans-2018-053878] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2018] [Revised: 01/24/2019] [Accepted: 02/11/2019] [Indexed: 02/01/2023] Open
Abstract
OBJECTIVE We investigated syphilis prevalence among men who have sex with men (MSM) in China, as well as potential risk factors. Our principal hypothesis was that syphilis would be associated with the use of recreational drugs such as methamphetamines. METHODS From April to October 2013, we used several methods to recruit MSM in Qingdao, collecting demographic/behavioural information via self-administrated questionnaires. Trained health workers collected blood for the Treponema pallidum particle assay (TPPA) with positives confirmed by a toluidine red unheated serum test. We used an unmatched case-control study to identify factors that might predict syphilis infection using multivariable logistic regression. RESULTS We recruited 447 MSM who agreed to participate and who completed syphilis testing. Of 71 (15.9%) syphilis-positive MSM, 44 (62.0%) used drugs. Of 376 (84.1%) syphilis-negative MSM, 186 (49.5%) used drugs. We found a positive association with syphilis for any recreational drug use (crude OR (cOR) 1.7, 95 % CI 1.0 to 2.8), frequent methamphetamine use (cOR 2.4, 95% CI 1.1 to 5.3) and multiple drug use (adjusted OR (aOR) 3.4, 95% CI 1.3 to 9.2). Syphilis-positive men were more likely to have a higher physical depression score (aOR 5.2, 95% CI 1.1 to 24.4), be > 30 years old (aOR 2.7, 95% CI 1.5 to 4.8), report a prior STI (aOR 4.1, 95% CI 2.3 to 7.3) and report a sex party experience (aOR 2.2, 95% CI 1.1 to 4.4). CONCLUSIONS Recreational drug use, depression and high-risk sexual behaviours were associated with syphilis infection among MSM in China. Only a multifaceted approach is likely be effective in control of both syphilis and HIV .
