M Siguier, J-M Molina
Preexposure prophylaxis of HIV with antiretroviral drugs is a prevention tool available in France since 2016, combined with the prevention methods already used (condoms, post-exposure treatment, rapid treatment of diagnosed HIV infections, etc.). It is targeted at populations at high risk of HIV infection, especially men who have sex with men, for whom traditional prevention methods are insufficient. We collected clinical research data, which resulted in the launch of preexposure prophylaxis in the United States and then elsewhere in the world, safety, tolerability and cost data, as well as ongoing research data (new molecules/methods of administration)...

OBJECTIVES: To review the main factors influencing the costs of nondaily oral preexposure prophylaxis (PrEP) with tenofovir (±emtricitabine). To estimate the cost reductions possible with nondaily PrEP compared with daily PrEP for different populations (MSM and heterosexual populations). DESIGN: Systematic review and data triangulation. METHODS: We estimated the required number of tablets/person/week for dosing regimens used in the HPTN 067/ADAPT (daily/time-driven/event-driven) and IPERGAY (on-demand) trials for different patterns of sexual intercourse...

Background: Nondaily dosing of oral preexposure prophylaxis (PrEP) may provide equivalent coverage of sex events compared with daily dosing. Methods: At-risk men and transgender women who have sex with men were randomly assigned to 1 of 3 dosing regimens: 1 tablet daily, 1 tablet twice weekly with a postsex dose (time-driven), or 1 tablet before and after sex (event-driven), and were followed for coverage of sex events with pre- and postsex dosing measured by weekly self-report, drug concentrations, and electronic drug monitoring...

: The current review re-conceptualizes seek and test strategies, particularly given the changing importance of HIV testing as care continuum entry for persons irrespective of their HIV status. Care continuum entry advances previous seek and test strategies for client engagement with two next-generation functions: use of testing to engage (or re-engage) HIV negative clients in preexposure prophylaxis (PrEP) care; and testing individuals who may already be known positives for care continuum re-entry. We review existing seek and test strategies for most impacted community members with a goal of optimizing care continuum entry as we move towards HIV transmission elimination...

BACKGROUND: Geosocial networking (GSN) smartphone apps are becoming the main venue for sexual encounters among Brazilian men who have sex with men (MSM). To address the increased HIV incidence in this population, preexposure prophylaxis (PrEP) was recently implemented in the Brazilian public health system in the context of combined HIV prevention. OBJECTIVE: This study aimed to describe the characteristics of MSM using GSN apps for sexual encounters, their awareness of prevention strategies, and willingness to use PrEP...

Uptake of preexposure prophylaxis (PrEP) has been slow, but is increasing. Although PrEP is indicated for many patients, it has been concentrated among men who have sex with men (MSM). Awareness of PrEP is limited among non-MSM individuals, and among some MSM. As such, individuals at risk for HIV who are unaware of PrEP must rely on their medical providers to initiate conversations about PrEP. Members of a national professional organization of HIV specialists with prescribing privileges, including physicians, nurse practitioners, and physician assistants, participated in an online survey ( n = 342) to characterize their PrEP prescribing behaviors and the demographic membership of their PrEP patients...

PURPOSE: The aim of this study was to identify sex venue-based networks among men who have sex with men (MSM) to inform HIV preexposure prophylaxis (PrEP) dissemination efforts. METHODS: Using a cross-sectional design, we interviewed MSM about the venues where their recent sexual partners were found. Venues were organized into network matrices grouped by condom use and race. We examined network structure, central venues, and network subgroups. RESULTS: Among 49 participants, the median age was 27 years, 49% were Black and 86% reported condomless anal sex (ncAS)...

Preexposure prophylaxis (PrEP) is a highly effective HIV prevention method; however, it is underutilized among women who are at risk for acquisition of HIV. Women comprise one in five HIV diagnoses in the United States, and significant racial disparities in new HIV diagnoses persist. The rate of new HIV diagnoses among black and African American women in 2015 was 16 times greater than that of white women. These disparities highlight the importance of HIV prevention strategies for women, including the use of PrEP...

PURPOSE OF REVIEW: The antiviral agent tenofovir is highly effective for the treatment of HIV and hepatitis B virus infections, and the older prodrug tenofovir disoproxil fumarate (TDF) is also a component of daily preexposure prophylaxis (PrEP) to reduce the risk of HIV infection in high-risk populations. Although TDF is well tolerated, the potential for kidney and bone toxicity has important implications for public health given the large number of individuals exposed to TDF worldwide...

Oral preexposure prophylaxis (PrEP) has been proven to be a safe and effective means of preventing HIV. The purpose of our literature review was to examine primary care provider knowledge and attitudes about prescribing PrEP. PubMed, CINAHL, Web of Science, and Scopus were searched and additional articles were identified through other sources, yielding 11 articles that met inclusion criteria. Overall, there was high variability among providers regarding attitudes, knowledge, and prescriptive practices related to PrEP...

OBJECTIVES: We undertook the economic evaluation of the double-blind randomized ANRS-IPERGAY trial, which showed the efficacy of on-demand preexposure prophylaxis (PrEP) with tenofovir disoproxil fumarate (TDF)-emtricitabine (FTC) in preventing HIV infection among high-risk MSM. DESIGN AND METHODS: The economic evaluation was prospective. Counseling, drugs (TDF-FTC at &OV0556;500.88 for 30 tablets), tests, visits, and hospital admissions were valued based on in-trial use...

Pre-exposure prophylaxis (PrEP) with TDF/FTC significantly reduces the risk for HIV-1 transmission, but, to date, nobody knows if PrEP can still be useful in case of viruses harboring resistances to TDF/FTC or if alternative antiretroviral drugs might be rather proposed in selected cases. We promote the debate by describing a case of an acute infection with multiresistant HIV that occurred in a young girl who started a relationship with an HIV-infected partner who had a known multiresistant HIV.

To ensure the health and safety of persons taking antiretroviral medication for HIV preexposure prophylaxis (PrEP), CDC guidelines recommend initial and follow-up laboratory testing. We assessed the rates of recommended testing using a commercial insurance claims database. Before taking PrEP, 45% of users were tested for HIV, 31% for creatinine, 55% for syphilis, 43% for chlamydia/gonorrhea, and 38% for hepatitis B. By 6 months after PrEP initiation, 38% were tested for HIV, 37% for creatinine, 49% for syphilis, and 39% for chlamydia/gonorrhea...

REVIEW
Iryna B Zablotska, Catherine C O'Connor
PURPOSE OF REVIEW: The aim of this study is to summarise the recent evidence from high-income settings about providers' ability to deliver on the UNAIDS goal of at least three million people at substantial risk of HIV infection with PrEP by 2020, including awareness and knowledge about PrEP, willingness to prescribe PrEP, current levels of prescribing and service delivery models and issues. RECENT FINDINGS: Awareness about PrEP among health providers is growing, but at different pace depending on provider type...

PURPOSE OF REVIEW: HIV prevention approaches that women can use and control are a priority. Results from topical and oral preexposure prophylaxis (PrEP) HIV prevention trials have produced inconsistent results in women. One of the main behavioural factors impacting effectiveness of PrEP has been suboptimal adherence. In this review, we examine biological factors that modulate topical PrEP efficacy, with particular focus on the vaginal microbiome. RECENT FINDINGS: Genital inflammation is an independent risk factor for HIV acquisition in women...

More than 3 decades since its emergence in the United States, HIV continues to spread and disproportionately affect socially marginalized groups. Preexposure prophylaxis (PrEP), a highly effective prevention strategy federally approved since 2012, could fundamentally alter the course of the epidemic. However, PrEP's potential has not been fully realized, in part because health care providers have been slow to adopt PrEP in clinical practice and have been selective in their discussion of PrEP with patients. This nonstandardized approach has constrained PrEP access...

Background: Young men who have sex with men (MSM) are disproportionately impacted by HIV. Preexposure prophylaxis (PrEP) could reduce HIV acquisition among youth, but sub-optimal adherence threatens effectiveness. Optimal metrics of PrEP adherence among adolescents have not been defined. Methods: The ATN 110 and 113 studies provided daily oral PrEP with tenofovir (TFV) disoproxil fumarate/emtricitabine over 48 weeks to a diverse population of MSM (15-22 years). Self-reported adherence was assessed and PrEP drug concentrations measured from hair and dried blood spot (DBS) samples; 23% of participants received Wisepill electronic monitoring devices...
