BACKGROUND Sub-Saharan Africa is the region with the highest HIV burden. Adolescent girls and young women (AGYW) in the age range of 15 to 24 years are twice as likely as their male peers to be infected, making females in sub-Saharan Africa the most at-risk group for HIV infection. It is therefore critical to prioritize access to HIV testing, prevention, and treatment for this vulnerable population. OBJECTIVE Using an implementation science framework, the purpose of this research protocol was to describe the approaches we propose to optimize engagement of AGYW in both the HIV prevention and care continuum and to determine the recruitment and testing strategies that identify the highest proportion of previously undiagnosed HIV infections. METHODS We will compare two seek recruitment strategies, three test strategies, and pilot adaptive linkage to care interventions (sequential multiple assignment randomized trial [SMART] design) among AGYW in the age range of 15 to 24 years in Homa Bay County, western Kenya. AGYW will be recruited in the home or community-based setting and offered three testing options: oral fluid HIV self-testing, staff-aided rapid HIV testing, or referral to a health care facility for standard HIV testing services. Newly diagnosed AGYW with HIV will be enrolled in the SMART trial pilot to determine the most effective way to support initial linkage to care after a positive diagnosis. They will be randomized to standard referral (counseling and a referral note) or standard referral plus SMS text message (short message service, SMS); those not linked to care within 2 weeks will be rerandomized to receive an additional SMS text message or a one-time financial incentive (approximately US $4). We will also evaluate a primary prevention messaging intervention to support identified high-risk HIV-negative AGYW to reduce their HIV risk and adhere to HIV retesting recommendations. We will also conduct analyses to determine the incremental cost-effectiveness of the seek, testing and linkage interventions. RESULTS We expect to enroll 1200 participants overall, with a random selection of 100 high-risk HIV-negative AGYW for the SMS prevention intervention (HIV-negative cohort) and approximately 108 AGYW who are living with HIV for the SMART design pilot of adaptive linkage to care interventions (HIV-positive cohort). We anticipate that the linkage to care interventions will be feasible and acceptable to implement. Lastly, the use of SMS text messages to engage participants will provide pilot data to the Kenyan government currently exploring a national platform to track and support linkage, adherence to treatment, retention, and prevention interventions for improved outcomes. CONCLUSIONS Lessons learned will inform best approaches to identify new HIV diagnoses to increase AGYW’s uptake of HIV prevention, testing, and linkage to care services in a high HIV-burden African setting.

BACKGROUND Gay, bisexual, and other men who have sex with men continue to bear a large burden of the HIV epidemic in the United States and are among the only populations with increasing incidence in recent years. OBJECTIVE The Together 5000 (T5K) Study aimed to enroll a US-based, racially diverse sample of HIV-negative men, transmen, and transwomen who are not on pre-exposure prophylaxis (PrEP) into an observational cohort to inform the design, implementation, scale-up, and evaluation of HIV prevention programs. METHODS We used internet-based strategies to enroll a large, racially diverse national sample of HIV-negative men, transmen, and transwomen aged 16 to 49 years at high risk of HIV acquisition via sexual networking apps. Study participants are contacted every 6 months (in between annual surveys) for a brief survey on HIV testing, HIV diagnosis, and PrEP use (ie, attempts to access, PrEP initiation, and PrEP discontinuation). Participants complete annual self-administered at-home HIV testing and Web-based surveys. Using baseline serologic data and self-reported HIV testing history, we reconstructed a cohort of persons who were HIV negative at 12 months before baseline to estimate HIV incidence leading up to cohort enrollment. RESULTS The study sample included 8777 participants from all 50 US states, Puerto Rico, and Guam; 50.91% (4468/8777) were persons of color and 25.30% (2221/8777) were young individuals aged 16 to 24 years. Per eligibility criteria, all T5K participants reported having sex with >2 male partners in the 90 days before enrollment, self-reported not having been diagnosed with HIV, and were not actively taking PrEP. In addition, 79.39% (6968/8777) reported >2 insertive condomless anal sex (CAS) acts, 61.02% (5356/8777) reported >1 receptive CAS acts in the past 90 days. Furthermore, most (7525/8777, 85.74%) reported never having taken PrEP. In total, 70.25% (6166/8777) were sent a self-administered at-home HIV test kit and 82.29% (5074/6166) of those sent a kit returned a sample for testing. The HIV incidence rate during the 12-month period leading up to enrollment was estimated to be 2.41 (95% CI 2.02-2.90) per 100 person-years. CONCLUSIONS A large, national, and racially diverse fully Web-based cohort of HIV-negative men, transmen, and transwomen at high risk for HIV seroconversion has successfully been recruited into longitudinal follow-up. This cohort is at high risk for HIV acquisition and can provide important insights related to the real-world uptake, impact, and equity of HIV prevention interventions in the United States. Participants can be invited to participate in trials aimed at testing strategies to improve the uptake of and engagement in these interventions. INTERNATIONAL REGISTERED REPORT RR1-10.2196/13715

Abstract Introduction Adolescent HIV prevention and treatment is a high priority for youth healthcare in sub-Saharan Africa. Methods This study employed concept mapping to identify factors that impact the implementation of HIV prevention and intervention programs for adolescents in sub-Saharan Africa. Key stakeholders including researchers, policymakers, and non-governmental organization (NGO) personnel constituting membership of the NIH-sponsored Adolescent HIV Prevention and Treatment Implementation Science Alliance responded to the question: “In your experience, what factors have facilitated or hindered implementation of evidence-based HIV prevention or treatment for adolescents in sub-Saharan Africa?” Participants generated statements in response to the focus question, sorted them into thematically relevant groups, and rated each statement on its importance and changeability. Results Through data analyses and participant feedback, 15 distinct themes were derived. “Workforce/Workflow” and “HIV Stigma and Adolescent Development” were rated highest for importance, and “Threshold Conditions for Treatment” and “Structure of Implementation Efforts” were rated most changeable. Conclusions Understanding implementation science determinants and mechanisms can facilitate the uptake of successful implementation and sustainment strategies for the prevention and treatment of HIV in a given context. We placed determinants and mechanisms within the Exploration, Preparation, Implementation, Sustainment (EPIS) framework to provide greater contextual integration with broader theories in implementation science. Implementers across multiple disciplines can use these findings to improve the scale-up of evidence-based practices for adolescent HIV prevention and treatment in sub-Saharan Africa. Implementation approaches that consider the determinants and mechanisms identified in this study and integrated in implementation frameworks will likely have utility for other health conditions and contexts.

Background: HIV testing is an essential gateway to HIV prevention and treatment services. However, HIV testing uptake remains low among men due to stigma, discrimination, and confidentiality concerns. HIV self-testing (HIVST) is an alternative HIV testing method that can address many of these barriers for men. We conducted a systematic review to examine HIVST uptake and intervention strategies among Men in Sub-Saharan Africa.Methods: We used a systematic approach to survey literature published from January 2010 to June 2020 using five electronic databases (PubMed-Medline, CINAHL Complete, PsychINFO, Google Scholar, and Web of Science) and a manual search. Studies were included if they were peer-reviewed, published in English, and examined HIVST willingness, uptake, and/or linkage to care and included men in Sub-Saharan Africa.Results: Sixty-three articles related to HIVST were reviewed. Of the included articles, 37 discussed HIVST uptake/acceptability and 24 discussed intervention strategies. Both oral swab and finger-prick methods had high acceptability with ease of access and availability of the test cited as important by men. Free HIVST kits were preferred by men. Secondary distribution of kits via peers, sexual partners, and female sex workers were successful.Conclusion: HIV self-testing is highly acceptable to men. More efforts are needed to develop policies to implement HIVST programs targeting men in Sub-Saharan Africa, including a focus on linkage to care in sub-Saharan Africa. Future interventions should directly target men independently in tandem with using peers and their romantic partners to promote self-testing among men in sub-Saharan Africa. HIVST kit distribution strategies should be combined with services that can offer confirmatory tests and counseling for men as well as linkage to care.

Two million two hundred thousand adults were newly HIV-infected in 2011, underscoring the urgent need for new, effective ways to prevent incident infections. Recently, the field of HIV prevention has gathered positive results from different strategies, among different populations, and with varying effect sizes, including the treatment of HIV-positive women and men in discordant couples, male circumcision of HIV-negative men in sub-Saharan Africa, a HIV vaccine evaluated in a community-based trial among HIV-negative men and women in Thailand, the use of vaginal gel formulation of TDF for HIV prevention in women in South Africa, pre-exposure prophylaxis (PrEP) with tenofovir disoproxil fumarate (TDF) or emtricitabine and TDF (TDF-FTC) among HIV-1-serodiscordant heterosexual couples from Kenya and Uganda, and PrEP with TDF-FTC among heterosexual men and women in Africa. Of these interventions, PrEP is an attractive policy because it does not directly interferes with the sexual intercourse, providing people a choice on HIV prevention regardless of cultural, religious, or social harnesses.

Compared with women and girls, proportionately fewer men and boys in sub-Saharan Africa receive HIV testing, treatment, and other services. This study determined factors associated with never testing for HIV and examined never testing as a predictor of sexual risk behavior among men in Zambia. The sample included 2,609 men aged 15 to 24 from the 2018 Zambia Demographic and Health Survey. Logistic regression results revealed that compared with men who ever tested for HIV, men who never tested were more likely to be younger, have less education, have no children, be unemployed, and belong to the low wealth bracket. They also had a higher likelihood of not using a condom at last sex but were less likely to have more than five lifetime sexual partners. HIV prevention programs can use sociodemographic characteristics to identify those who have a lower likelihood of testing for HIV. Prevention programs can use sociodemographic characteristics to develop profiles of those who may especially need to be targeted by initiatives to promote HIV testing. Awareness does not always engender behavior change; therefore, in addition to knowledge of HIV status, risk reduction should also be emphasized.

In sub-Saharan Africa, HIV incidence andprevalence remain disproportionately high among women.Vaginal rings (VRs) have been formulated for the deliveryof antiretroviral-based microbicides, and their favorablesafety and tolerability profiles reported in clinical studies.Although the concept of drug release through a VR hasexisted since 1970, and VRs have been marketed since1992 for contraceptive or hormone replacement purposes,VR use as a microbicide delivery system is a novelapplication. This is the first study to evaluate VR adherenceamong African women in the context of its potential use asan HIV prevention method, to examine predictors ofadherence, and to describe clinical or contextual reasonsfor VR removals or nonadherence. This was a randomizedtrial of the safety and acceptability of a placebo VR wornfor 12 weeks in 170 HIV-negative, African women aged18–35 in four clinic sites in South Africa and Tanzania.The findings suggest that adherence to VR use in thecontext of HIV prevention trials in these communitiesshould be high, thereby enabling more accurate assessmentof an active microbicide safety and efficacy.Keywords Vaginal ring ?
