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 multi-resistant HIV that occurred in a young girl who started a relationship with a HIV-infected partner who had a known multi-resistant 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...

BACKGROUND: HIV preexposure prophylaxis (PrEP) using daily oral tenofovir-disoproxil-fumarate/emtricitabine (TDF/FTC) is effective for preventing HIV acquisition, but concerns remain about its potential kidney toxicity. This study examined kidney function in individuals using PrEP in real-world clinical settings. SETTING: Demonstration project in two sexually transmitted infection clinics and a community health center. METHODS: We evaluated kidney function among men who have sex with men and transgender women taking TDF/FTC PrEP for up to 48 weeks...

BACKGROUND: Named sex- or needle-sharing partners of HIV-positive individuals are a priority prevention population due to their known HIV exposure. Understanding postexposure and preexposure prophylaxis (PEP and PrEP) awareness and use among them is important for successful interventions. METHODS: Data from notified partners of HIV-positive individuals (New York City, May 2015-April 2017) were analyzed to describe PEP/PrEP awareness, provider discussion, and use by sociodemographic and risk characteristics...

Public health field services for sexually transmitted infections (STIs) have not adequately evolved to address the expanding scale of the STI problem, its concentration among men who have sex with men, the emergence of new communication technologies and the availability of antiretroviral therapy as a cornerstone of human immunodeficiency virus (HIV) prevention. Field services need to modernize. Modernization should seek to expand field services objectives beyond sex partner STI testing and treatment to include: HIV testing of persons with bacterial STI and their partners, including efforts to promote frequent HIV/STI testing; increased condom access; linkage and relinkage to HIV care and promotion of viral suppression; preexposure prophylaxis promotion; linkage to long-acting contraception; and referral for health insurance...

BACKGROUND: Human immunodeficiency virus preexposure prophylaxis (PrEP) uptake remains low in high-risk populations. Sexually transmitted infection (STI) clinics reach PrEP-eligible persons and may be ideal settings to model PrEP implementation. METHODS: Consenting PrEP-eligible patients identified at Chicago Department of Public Health STI Clinics were actively referred to PrEP partner sites between June 1, 2015, and May 31, 2016. Outcomes included successful contact by a partner site, linkage to a partner site, and receipt of a PrEP prescription...

Importance: Adolescents represent a key population for implementing preexposure prophylaxis (PrEP) interventions worldwide, yet tenofovir disoproxil fumarate/emtricitabine (TDF/FTC) for PrEP is only licensed for adults. Objective: To examine the safety of and adherence to PrEP along with changes in sexual risk behavior among adolescent men who have sex with men (MSM). Design, Setting, and Participants: Adolescent Medicine Trials Network for HIV/AIDS Interventions 113 (Project PrEPare) was a PrEP demonstration project that evaluated the safety, tolerability, and acceptability of TDF/FTC and patterns of use, rates of adherence, and patterns of sexual risk behavior among healthy young MSM aged 15 to 17 years...

In the United States, black men who have sex with men (MSM) are the group most affected by the HIV/AIDS epidemic. Pre-exposure prophylaxis (PrEP) is an important new HIV prevention strategy that may help reduce new HIV infections among black MSM. This analysis examined the association between HIV/AIDS conspiracy beliefs and intentions to adopt PrEP among 224 black MSM. The likelihood of adopting PrEP was assessed and more than half (60%) of the study population indicated a high intention to adopt PrEP. HIV/AIDS genocidal and treatment-related conspiracies were assessed using scales previously validated with black MSM...

BACKGROUND: An estimated 1.2 million American adults engage in sexual and drug use behaviors that place them at significant risk of acquiring HIV infection. Engagement in health care for the provision of daily oral antiretroviral medication as preexposure prophylaxis (PrEP), when clinically indicated, could substantially reduce the number of new HIV infections in these persons. However, resources to cover the financial cost of PrEP care are anticipated barriers for many of the populations with high numbers of new HIV infections...

We analyzed the concept of risk compensation and how it has been applied in HIV prevention, paying particular attention to the strategy of HIV preexposure prophylaxis (PrEP). In risk compensation, reduced perceptions of risk after the introduction of a preventative intervention lead to more frequent risk-taking behavior. Such a change may undermine the intervention's protective benefits. We found that many studies purporting to investigate risk compensation do not assess or report changes in perceptions of risk, instead relying on behavioral measures...
