Pre-exposure prophylaxis

The FDA's approval of long-acting injectable cabotegravir pre-exposure prophylaxis (LAI PrEP) as an alternative to daily oral PrEP represents a crucial development in HIV prevention, particularly for American Black cisgender women who face high HIV-1 risks. Yet, uptake may be hindered by racial and gender inequities. Addressing these requires learning from the roll-out of oral PrEP, creating culturally tailored PrEP campaigns, and enhancing provider training to meet Black women's needs. Tools for discussing PrEP within personal relationships and product preference research tailored to Black women's needs are essential for effective LAI PrEP delivery...

INTRODUCTION: Following HIV testing services (HTS), the World Health Organization recommends prompt linkage to prevention and treatment. Scale-up of effective linkage strategies is essential to achieving the global 95-95-95 goals for maintaining low HIV incidence by 2030 and reducing HIV-related morbidity and mortality. Whereas linkage to care including same-day antiretroviral therapy (ART) initiation for all people with HIV is now routinely implemented in testing programmes, linkage to HIV prevention interventions including behavioural or biomedical strategies, for HIV-negative individuals remains sub-optimal...

OBJECTIVES: Although oral pre-exposure prophylaxis (PrEP) for HIV is being rolled out in West Africa, data on sexually transmitted infections (STIs) in PrEP users are scarce. We assessed the prevalence, incidence and determinants of bacterial STIs in men who have sex with men (MSM) taking PrEP in Burkina Faso, Côte d'Ivoire, Mali and Togo. METHODS: A prospective cohort study among MSM initiating PrEP as part of a comprehensive HIV prevention package was conducted between 2017 and 2021 in community-based clinics in the four study countries...

BACKGROUND: Community pharmacies are ideal venues for pre-exposure prophylaxis (PrEP) delivery. Pharmacists and pharmacy-based PrEP delivery programs have the potential to improve access. OBJECTIVES: This study elicited preferences for attributes of a hypothetical community pharmacy-based PrEP delivery program among US men who have sex with men (MSM) and assessed predictors of their preferences. METHODS: Data were collected via a cross-sectional anonymous survey of US MSM, who were aged 18-65 years, not transgender, reported HIV status negative/unknown, and PrEP eligible...

INTRODUCTION: Women with cardiovascular disease may be at increased risk of hypertensive disorders of pregnancy (HDP). We aimed to: (1) Investigate the occurrence of HDP in a cohort of pregnant women with cardiovascular disease and compare it with the occurrence in the general population. (2) Assess the association between maternal cardiovascular risk and risk of HDP. MATERIAL AND METHODS: We reviewed clinical data on a cohort of 901 pregnancies among 708 women with cardiovascular disease who were followed at the National Unit for Pregnancy and Heart Disease and gave birth at Oslo University Hospital between 2003 and 2018...

Short- and long-term impacts of the climate crisis continue to be felt across the public health landscape. Many individuals marginalized by the climate crisis also navigate a higher likelihood of exposure to HIV. By understanding this relationship, we can better position HIV prevention, and pre-exposure prophylaxis (PrEP) programs specifically, to meet user needs in communities experiencing the effects of the climate crisis. In support, we propose four recommendations for mitigating the impact of the climate crisis on those who may benefit from PrEP: (1) leverage existing and emerging research and lived experience to intentionally target and appropriately reach individuals affected by the climate crisis who may need or want PrEP; (2) emphasize the need for more climate-resilient PrEP products within the research and development pipeline; (3) build a continued understanding of the role of the climate crisis-HIV relationship in product introduction through national collaboration; and (4) strengthen the integration of PrEP service delivery and response to intimate partner violence...

INTRODUCTION: Pre-exposure prophylaxis (PrEP) is an effective method for prevention of HIV transmission. Female sex workers (FSW) in Malaysia are at substantially increased risk of acquiring HIV compared to the general female population, yet little is known about this population's current HIV prevention practices or acceptance of PrEP. This study aims to inform the culturally relevant implementation of PrEP through the qualitative exploration of (1) the potential need for PrEP in this population and (2) the factors that determine FSW willingness to use oral PrEP...

Transmasculine people (TM) constitute an invisibilized group within the transgender population. Little is known about their relationship to sexuality in transgender medicine. Their presence and needs are still unacknowledged within HIV prevention research and services. Pre-exposure prophylaxis (or PrEP) is an oral medication that prevents HIV in HIV-negative individuals at risk of infection with the virus. This paper proposes to bring TM back into the focus of PrEP research by questioning how they navigate and situate themselves in relation to existing PrEP categorization and services, and how they think about and (re)shape the meanings of PrEP...

BACKGROUND: Men who have sex with men (MSM) in British Columbia (BC) are disproportionately affected by infectious syphilis and HIV. In this study, we developed a co-interaction model and evaluated the impact and effectiveness of possible interventions among different MSM subgroups on the syphilis epidemic. METHODS: We designed a deterministic compartmental model, which stratified MSM by HIV status and HIV pre-exposure prophylaxis (HIV-PrEP) usage into (1) HIV-negative/unaware MSM (HIV-PrEP not recommended, not on HIV-PrEP), (2) HIV-negative/unaware MSM with HIV-PrEP recommended (not on HIV-PrEP), (3) HIV-negative/unaware MSM actively on HIV-PrEP, and (4) MSM diagnosed with HIV...

Despite advances in treatment, HIV infection remains an important cause of morbidity and mortality, with more than 30 000 new cases diagnosed in the United States each year. There are several interventions traditionally used to prevent HIV transmission, but these vary in effectiveness and there are challenges to their implementation. In 2014, the Centers for Disease Control and Prevention published initial guidance on the use of antiretroviral pre-exposure prophylaxis (PrEP) to prevent transmission of HIV infection in persons at risk based on multiple studies that showed it to be highly efficacious in various populations...

BACKGROUND: There are limited population-level data on the pre-exposure prophylaxis (PrEP) care continuum in eastern Africa. Here, we assessed the PrEP care continuum following PrEP rollout in a Ugandan community with ∼40% HIV seroprevalence. METHODS: We used cross-sectional population-based data collected between September 3 and December 19, 2018 from a Lake Victoria fishing community in southern Uganda to measure levels of self-reported PrEP knowledge, ever use, and discontinuation following 2017 PrEP rollout via a U...

We assessed acceptability of nonoral HIV pre-exposure prophylaxis (PrEP) formulations among transgender women (TW) engaged in street-based sex work in Baltimore, Maryland. In a K -means cluster analysis, TW ( N =36) were partitioned into groups characterized by high interest in long-acting injectable PrEP only ( Injectable Enthusiasts , 36%), high interest in injectables and subdermal implants ( Long-Acting Acceptors , 36%), and low interest across PrEP formulations ( Non-Acceptors , 28%). TW's interest in novel PrEP agents varied widely across formulations (range: 22-66%) and clustered around numerous relational, occupational, and structural factors, highlighting the importance of availing multiple PrEP formulations for this impacted population...

PURPOSE: The objectives of this study were to assess the knowledge of HIV and pre-exposure prophylaxis (PrEP) in transgender adolescents and young adults (AYAs) and to test the acceptability of rapid HIV testing among transgender adolescents in a multidisciplinary gender clinic. METHODS: Participants enrolled on the same day as their mental health or medical appointment in a multidisciplinary gender clinic. They completed survey questions regarding HIV and PrEP knowledge and were also offered an optional same-day, rapid, fourth-generation HIV test...

BACKGROUND: Despite accounting for more than half of new Human Immunodeficiency Virus diagnoses in the United States, the South has fewer than 30% of all pre-exposure prophylaxis users. Pre-exposure prophylaxis access geospatial analyses have focused on drive time but analyses along public transit routes have not been evaluated. Given the proximity to pharmacists and pharmacies, involvement in pre-exposure prophylaxis services may increase access and uptake of this preventative health need...

PURPOSE: In the United States, youth experience suboptimal HIV pre-exposure prophylaxis (PrEP) adherence. One common idea posits that this is due to their developing decision-making skills. However, quantitative evidence of this assumption is limited. We therefore examined whether individual decision-making factors, such as HIV risk perception and sexual behavior, predicted PrEP adherence in a national trial of young sexual and gender minorities (YSGMs). METHODS: In 2019-2021, the Adolescent Medicine Trials Network for HIV Interventions 142 study enrolled 225 PrEP users (ages 16-24) throughout the country...

BACKGROUND: Despite advances in human immunodeficiency virus (HIV) prevention methods, such as the advent of pre-exposure prophylaxis (PrEP), the number of people with newly acquired HIV remains high, particularly in at-risk groups. A prophylactic HIV vaccine could contribute to reduced disease prevalence and future transmission and address limitations of existing options, such as suboptimal long-term adherence to PrEPs. METHODS: This qualitative study aimed to capture perceptions towards and acceptance of prophylactic HIV vaccination in three adult populations in the United States: the general population, 'at-risk' individuals (e...

INTRODUCTION: The government-funded pre-exposure prophylaxis (PrEP) programme was targeted to those aged under 30 years or serodiscordant couples and implemented in September 2018-October 2020 in Taiwan. The study aimed to examine the effectiveness of the programme and the relationship between sexually transmitted disease (STD) and HIV seroconversion. METHODS: This study was a retrospective cohort analysis with questionnaires designed for participants who joined the aforementioned programme in the PrEP-designated hospitals...

BACKGROUND: Pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) prevent HIV among individuals at high risk for acquisition. Pre-existing structural barriers to PrEP/PEP access among rural patients may be exacerbated further if pharmacies do not keep PrEP/PEP in stock, constituting a significant barrier to mitigating the HIV epidemic. OBJECTIVES: To compare PrEP/PEP availability for same-day pickup in rural vs urban Georgia and Pennsylvania pharmacies...

Young MSM (YMSM), aged 15-24, account for nearly half of new HIV infections in Thailand. Pre-exposure prophylaxis (PrEP) is an effective prevention medicine for populations at substantial HIV risk, yet YMSM frequently have suboptimal uptake of and adherence to PrEP. We conducted 35 in-depth interviews with YMSM to explore barriers and facilitators of both PrEP initiation and adherence. Interviews also elicited the perceptions and experiences of healthcare providers (HCPs) working with YMSM at three clinics in Bangkok...

BACKGROUND: Daily oral pre-exposure prophylaxis (PrEP) is an effective HIV prevention option for those who are most vulnerable to HIV infection, especially young women (YW). Objection by or lack of support from male sexual partners has been shown to impact YW's ability to take PrEP consistently. We explored the views of YW, and male partners and male peers of YW in Siaya County, Western Kenya, to illustrate how men influence, and can support, YW in using PrEP. METHODS: We used Photovoice to capture the views of YW ages 18-24 who were currently or previously enrolled in the DREAMS program and with current or previous experience taking PrEP...
