OBJECTIVES: HIV pre-exposure prophylaxis (PrEP) is not approved in Switzerland and therefore must be paid for by the users themselves. We conducted a survey to find out whether men who have sex with men (MSM) in Switzerland are already taking PrEP, or are considering using it, and whether it is being taken under medical supervision or not. METHODS: Grindr® is a geosocial networking app for MSM. Between 5 and 24 January 2017, users of the app who were located in Switzerland by a global positioning system (GPS) were asked to participate in a ten-question survey on PrEP use...

BACKGROUND: The risks of HIV transmission associated with the opioid epidemic make cost-effective programs for people who inject drugs (PWID) a public health priority. Some of these programs have benefits beyond prevention of HIV-a critical consideration given that injection drug use is increasing across most United States demographic groups. To identify high-value HIV prevention program portfolios for US PWID, we consider combinations of four interventions with demonstrated efficacy: opioid agonist therapy (OAT), needle and syringe programs (NSPs), HIV testing and treatment (Test & Treat), and oral HIV pre-exposure prophylaxis (PrEP)...

This economic evaluation aims to support policy-making on the combined use of pre-exposure prophylaxis (PrEP) with HIV vaccines in development by evaluating the potential cost-effectiveness of implementation that would support the design of clinical trials for the assessment of combined product safety and efficacy. The target study population is a cohort of men who have sex with men (MSM) in the United States. Policy strategies considered include standard HIV prevention, daily oral PrEP, HIV vaccine, and their combination...

BACKGROUND: Transgender people are disproportionately affected by HIV. Despite their high vulnerability to HIV, lack of adequate epidemiological and surveillance data related to this population in many countries prevents provision of appropriate services. This paper summarizes descriptive findings from a national integrated biological and behavioral survey and discusses policy implications of the findings on HIV prevention among transgender women in Cambodia. METHODS: This cross-sectional study was conducted between December 2015 and February 2016...

CC-chemokine receptor 5 serves as the coreceptor for the HIV-1 R5 strains, which are responsible for the majority of HIV transmissions. A deletion of 32 nucleotides in the gene encoding this receptor (termed CCR5-Δ32) leads to the suppression of CC-chemokine receptor 5 presentation at the cell surface, thus impeding process of HIV entry into the cell. Individuals homozygous for the CCR5-Δ32 allele are resistant to infection with HIV-1 R5 strains, and are extremely rare among HIV-1-infected individuals. We have described a case of person homozygous for CCR5-Δ32, who was infected with subtype B HIV-1...

During the past three decades, non-human primate (NHP) models have gained an increasing importance in HIV basic and translational research. In contrast to natural host models, infection of macaques with virulent simian or simian-human immunodeficiency viruses (SIV, SHIV) results in a disease that closely resembles HIV infection and AIDS. Although there is no perfect animal model, and each of the available models has its benefits and limitations, carefully designed NHP studies with selection of experimental variables have unraveled important questions of basic pathogenesis and have provided the tools to explore and screen intervention strategies...

This study describes the self-reported use of pre-exposure prophylaxis (PrEP) in the personal advertisements of men seeking sex with men in the United States on the online classified advertisement site, Craigslist. Overall self-reported PrEP use was low (0.20%; 95% confidence interval (CI)=0.18-0.22). However, PrEP use in personal ads was described in conjunction with seeking sexual risk behaviours including 'bareback' sex (22.7%; 95% CI=17.7-27.7%) and sex with substance use (26.8%; 95% CI=21.5-32.1%). Only 4...

BACKGROUND: Despite continued reductions in the number of HIV cases reported among San Francisco men who have sex with men (MSM) and the HIV-prevention potential offered by pharmaceutical tools such as pre-exposure prophylaxis (PrEP), there are uncertainties, particularly given reported decreases in consistent condom use. A key uncertainty is what groups of MSM should be targeted. The present study estimates the distribution of behavioral patterns prior to infection among San Francisco MSM newly infected with HIV in 2014...

BACKGROUND: Clinical trials have demonstrated the effectiveness of human immunodeficiency virus (HIV) pre-exposure prophylaxis (PrEP) for reducing HIV acquisition. Understanding how HIV care providers are prescribing PrEP is necessary to ensure success of this prevention strategy. METHODS: During 2013-2014, we surveyed US HIV care providers who also provided care to HIV-negative patients. We estimated percentages who had prescribed PrEP and assessed associations between provider characteristics and PrEP prescribing...

Migrant miners from Mozambique who work in South Africa and their partners are at substantial risk for HIV infection. We conducted a cross-sectional study to assess the willingness of migrant miners and female partners of miners to take short-term pre-exposure prophylaxis (PrEP) for prevention of HIV acquisition. The study was conducted in Gaza Province, Mozambique, between September and October 2015. A total of 131 male miners and female partners of male miners completed a questionnaire. Subsequently, 48 in-depth interviews among male miners and female partners of miners and 3 focus-group discussions (6 participants each) among female partners of miners were conducted...

OBJECTIVE: HIV Pre-exposure prophylaxis (PrEP) decreases risk of HIV acquisition however its efficacy is closely dependent on adherence. There is also concern that the preventive effect of PrEP may be offset by risk compensation, notably an increase in condomless anal sex. DESIGN: Multi-site, open-label demonstration study that recruited people at current or recent risk of HIV infection in Melbourne, Australia. METHODS: Participants were recruited from three general practice clinics and one sexual health clinic in Melbourne and consented to take daily tenofovir/emtricitabine for 30 months...

OBJECTIVES AND DESIGN: Hepatitis C virus (HCV) has been recognised as an emerging sexually transmitted infection (STI) among HIV-positive men who have sex with men (MSM). However, HIV-negative MSM at high risk for HIV might also be at increased risk for HCV. We studied the HCV prevalence in HIV-negative MSM who start pre-exposure prophylaxis (PrEP) in Amsterdam. Phylogenetic analysis was used to compare HCV strains obtained from HIV-negative and HIV-positive MSM. METHODS: At enrolment in the Amsterdam PrEP (AMPrEP) demonstration project, HIV-negative MSM were tested for the presence of HCV antibodies and HCV RNA...

The purpose of our study was to increase the rate of children with appropriate HIV-PEP regimens among those diagnosed with sexual assault in The Children's Hospital of Philadelphia Emergency Department (ED). The outcome measure was the percent of patients receiving correct HIV-PEP. We retrospectively reviewed 97 charts over 31 months to define the baseline rate of children receiving appropriate HIV-PEP regimens (pre QI-implementation period: 2/2012-8/2014). Among children in which HIV-PEP was indicated following sexual assault, 40% received the recommended 28-day course...

Non-medical, community-based workers play a critical role in supporting people living with (or at risk of acquiring) HIV along the care continuum. The biomedical nature of promising advances in HIV prevention, such as pre-exposure prophylaxis and treatment-as-prevention, requires frontline workers to be knowledgeable about HIV science and treatment. This study was developed to: measure knowledge of HIV science and treatment within the HIV non-medical workforce, evaluate workers' familiarity with and attitudes toward recent biomedical interventions, and identify factors that may affect HIV knowledge and attitudes...
