Men who have sex with men (MSM) who attend group-sex events often engage in risky sexual behaviors that contribute to the high human immunodeficiency virus (HIV) incidence among this population. We conducted an online survey with 211 New York City MSM who attended sex parties in the prior year and asked them to describe their behaviors and perceptions of risk. We compared responses from HIV-positive-undetectable men (n = 36), HIV-negative men on pre-exposure prophylaxis (PrEP; n = 62), and HIV-negative men never on PrEP (n = 113)...

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...

The HPTN 067/Alternative Dosing to Augment Pre-Exposure Prophylaxis Pill Taking (ADAPT) study evaluated daily and non-daily dosing schedules for oral pre-exposure prophylaxis (PrEP) to prevent HIV. A qualitative sub-study including focus groups and in-depth interviews was conducted among men who have sex with men participating in New York City to understand their experience with PrEP and study dosing schedules. The 37 sub-study participants were 68% black, 11% white, and 8% Asian; 27% were of Hispanic/Latino ethnicity...

BACKGROUND: PrEP stigma (i.e., negative attitudes toward PrEP users) has been widely documented and is considered a significant barrier to implementation. However, few studies have examined PrEP stigma using implicit measures designed to reduce demand characteristics in responding. This study examined implicit PrEP- and HIV-related stigma among gay and bisexual men using geospatial social networking applications (i.e., "hookup apps"). METHODS: Participants were presented with four simulated online profiles (pre-tested for comparability) paired with each of the following characteristics: HIV-negative, HIV-positive, on PrEP, or Substance User...

In the U.S., transgender and other gender minority (TG) youth are an at-risk group understudied in HIV prevention and treatment. This study sought to characterize the HIV prevention and care continua in a diverse sample of 181 sexually-active TG ages 16-24 years (mean age = 20.7 years; 76.8% trans feminine; 69.1% youth of color) recruited July-December 2015 in 14 U.S. cities. Overall, 30.9% reported living with HIV, of which 71.4% were on antiretroviral therapy (ART) and 55.0% were medication adherent; 65...

BACKGROUND: Wide-scale implementation of oral tenofovir-based pre-exposure prophylaxis (PrEP) for HIV prevention is now policy in many settings. However, the optimal frequency for monitoring kidney function remains uncertain. We investigated the impact of 6-monthly compared to 3-monthly creatinine clearance (CrCl) monitoring on the identification of moderate kidney dysfunction, defined as CrCl <60 mL/min. METHODS: Data were from two prospective daily oral PrEP studies in Kenya and Uganda: the Partners PrEP Study, a randomized safety and efficacy trial of PrEP that conducted 3-monthly CrCl monitoring (n=4404) and the Partners Demonstration Project (n=954), an open-label delivery study of PrEP that used 6-monthly monitoring...

Debate remains as to the relative HIV transmission contributions from individuals who are recently HIV infected and individuals who have long-term infections. In this study, we examine the relationship between new HIV seroconversions occurring among young Black men who have sex with men (YBMSM) and network proximity to recently or long-term HIV infected individuals. A cohort of YBMSM (N = 618) was generated through respondent driven sampling across three waves. A recent HIV infection was defined as either: 1) a confirmed seroconversion ≤9 months prior to interview date or 2) a laboratory confirmed acute infection; long-term HIV infected individuals were defined as a diagnosis date ≥9 months prior to interview date...

Men who have sex with men (MSM) have a high HIV burden and also often face multiple other challenges accessing HIV services, including legal and social issues. Although Swaziland recently started responding with interventions for MSM, significant gaps still exist both in information and programming. This study aimed to explore the HIV prevention needs of MSM in Swaziland, including factors elevating their risks and vulnerabilities to HIV infection; to find out what HIV prevention strategies exist; and to determine how best to meet the prevention needs of MSM...

HIV testing is the gateway to biomedical means of prevention and treatment. Identifying predictors of HIV testing is important to inform future preventive interventions. Of 444 men who have sex with men without known HIV infection enrolled in a study in Hong Kong, 64% had ever been HIV-tested. Testers were generally older, better educated, had a higher monthly income, and more likely self-identified as gay. Testers often used Internet and frequented saunas for sex networking, compared with non-testers attending bars, massage centres and public toilets...

Research on the association between viewing condomless sex in sexually explicit media (SEM) and engaging in risk behavior suggests the need for SEM-based safer sex messaging (e.g., PrEP, condom use), though few studies have considered viewer willingness to watch SEM containing HIV/STI prevention messages. Online survey data from a racially diverse sample of 859 men and women were used to investigate factors associated with willingness to watch SEM with safer sex messaging. Analyses were conducted separately for three groups: heterosexual men and other men who only report sex with women, heterosexual women and other women who only report sex with men, and gay, bisexual, and other men who have sex with men...

Oral pre-exposure prophylaxis (PrEP) can prevent HIV transmission. Yet, some may prefer not to take systemic daily medication. MTN-017 was a 3-period, phase 2 safety and acceptability study of microbicide gel applied rectally either daily or before and after receptive anal intercourse (RAI), compared to daily oral tablet. At baseline, cisgender men and transgender women who reported RAI (N = 187) rated the daily oral regimen higher in overall liking, ease of use, and likelihood of future use than the gel regimens...

Men who have sex with men (MSM) account for nearly 70% of new HIV diagnoses, with young black MSM at the highest risk for infection in the United States. Pre-exposure prophylaxis (PrEP) can decrease HIV acquisition in at-risk individuals by over 90%. However, therapeutic efficacy requires a daily pill, posing adherence challenges. Experimental modalities, including injectable PrEP given once every 2 months, may improve adherence among those most in need. To assess interest in and preference for injectable PrEP, an online survey was mounted on two popular MSM sexual networking apps...

Ocimum plants are traditionally used to manage HIV/AIDS in various African countries. The effects of Ocimum labiatum extract on HIV-1 protease (PR) and reverse transcriptase (RT) is presented here along with characterization of an identified bioactive compound, achieved through ¹H- and (13)C-NMR. The extract's effect on HIV-1 replication was assessed by HIV-1 p24 antigen capture. Cytotoxicity of samples was evaluated using tetrazolium dyes and real-time cell electronic sensing (RT-CES). Ocimum labiatum inhibited HIV-1 PR with an IC50 value of 49...

BACKGROUND: It is unknown if extremely early initiation of antiretroviral therapy (ART) may lead to long-term ART-free HIV remission or cure. As a result, we studied 2 individuals recruited from a pre-exposure prophylaxis (PrEP) program who started prophylactic ART an estimated 10 days (Participant A; 54-year-old male) and 12 days (Participant B; 31-year-old male) after infection with peak plasma HIV RNA of 220 copies/mL and 3,343 copies/mL, respectively. Extensive testing of blood and tissue for HIV persistence was performed, and PrEP Participant A underwent analytical treatment interruption (ATI) following 32 weeks of continuous ART...

OBJECTIVE: Although postmenopausal women have behavioral and biological risk factors for HIV infection, the activity of pre-exposure prophylaxis agents in older adults has not been well studied. DESIGN: We used an ex-vivo approach to compare the tissue concentrations of tenofovir diphosphate (TFVdp) and emtricitabine triphosphate (FTCtp) in cervical tissues from premenopausal and postmenopausal women. METHOD: Cervical explants from 16 premenopausal and 11 postmenopausal women were incubated in 10-300 μg/mL tenofovir or emtricitabine for 24 hours...

Combination prevention efforts are now recommended toward reducing HIV incidence among men who have sex with men (MSM). Understanding the perceptions of both MSM and service providers is critical to informing the development of prevention packages and ultimately improving intervention effectiveness. This study assessed the preferences of MSM and health service providers in the administration of HIV-prevention efforts. Qualitative data were gathered from a series of separate MSM and health care provider focus groups in 2 South African cities...

Host genetic variation modifying HIV-1 acquisition risk can inform development of HIV-1 prevention strategies. However, associations between rare or intermediate-frequency variants and HIV-1 acquisition are not well studied. We tested for the association between variation in genic regions and extreme HIV-1 acquisition phenotypes in 100 sub-Saharan Africans with whole genome sequencing data. Missense variants in immunoglobulin-like regions of CD101 and, among women, one missense/5' UTR variant in UBE2V1, were associated with increased HIV-1 acquisition risk (p = 1...

Background: We estimated the HIV incidence reduction in Australia corresponding to achieving the UNAIDS 90-90-90 targets by 2020 and extended targets of 95-95-95 by 2030, in combination with various scale-ups of HIV testing, primary prevention and pre-exposure prophylaxis (PrEP) among high-risk men who have sex with men (MSM). These projections were evaluated against the target of achieving a 90% reduction in HIV incidence by 2030 compared with 2010 levels. Methods: A mathematical model was used to project annual HIV incidence for combinations of HIV care cascade targets, testing frequencies, primary prevention coverages and levels of PrEP scale-up...
