Pre-exposure prophylaxis (PrEP) with daily oral tenofovir/emtricitabine dramatically reduces HIV risk in men who have sex with men (MSM). However, uptake is slow worldwide.We administered anonymous cross-sectional questionnaires to MSM presenting for anonymous HIV testing at a Toronto sexual health clinic at four successive time points during the period 2013-2016. We assessed trends in PrEP awareness, acceptability, and use over time using the Cochran-Armitage Trend Test, and identified barriers to using PrEP by constructing "PrEP cascades" using 2016 data. We assumed that to use PrEP, MSM must (a) be at risk for HIV, (b) be at objectively high risk (HIRI-MSM score ≥ 10), (c) perceive themselves to be at medium-to-high risk, (d) be aware of PrEP, (e) be willing to use PrEP, (f) have a family doctor, (g) be comfortable discussing sexual health with that doctor, and (h) have drug coverage/be willing to pay out of pocket.MSM participants were mostly white (54-59.5%), with median age 31 years (IQR = 26-38). PrEP awareness and use increased significantly over time (both p < 0.0001), reaching 91.3% and 5.0%, respectively, in the most recent wave. Willingness to use PrEP rose to 56.5%, but this increase did not reach statistical significance (p = 0.06). The full cascade, ABCDEFGH, suggested few could readily use PrEP under current conditions (11/400 = 2.8%). The largest barriers, in descending order, were low self-perceived HIV risk, unwillingness to use PrEP, and access to PrEP providers.To maximize its potential public health benefits, PrEP scale-up strategies must address self-perceived HIV risk and increase access to PrEP providers.

Background
HIV post-exposure prophylaxis following sexual exposure (PEPSE) and pre-exposure prophylaxis (PrEP) are used by people at sexual risk of HIV acquisition including men who have sex with men (MSM). Owing to the high risk of HIV seroconversion due to on-going risk behaviours, it is becoming commonplace for HIV-negative MSM requiring PEPSE (e.g. HIV sexual-exposure within 72-hours) to transition immediately to PrEP following the 28-days of PEPSE. We aimed to review how frequently PrEP is discussed and used by MSM following PEPSE.Method
We reviewed the electronic notes of MSM who had accessed PEPSE between January 2018 – November 2020 and collected information on sexual assault, recreational drug use at the time of PEPSE initiation, whether direct transition to PrEP had been discussed, and if PrEP had been initiated after PEPSE.Results
During the study period, 277 MSM accessed PEPSE. The median age was 32 years (IQR 26–43), 17 (6%) started PEPSE following a sexual assault, 36 (13%) were using recreational drugs during sex and 30(11%) had used PrEP previously. Discussion about direct transition to PrEP after PEPSE was documented in 155 (56%) MSM, including 128 (51%) MSM who had never used PrEP before, and 67 (24%) MSM actually transitioned directly from PEPSE to PrEP. Clinicians were more likely to discuss PEPSE to PrEP transition in MSM with prior PrEP use (p<0.0001), and MSM were more likely to transition to PrEP from PEPSE if they had used PrEP previously (p<0.00001).Conclusion
Only 56% of MSM who used PEPSE had a documented discussion about transitioning to PrEP and only a 24% actually transitioned from PEPSE to PrEP. Where indicated, MSM who access PEPSE should have a documented discussion and ideally transition immediately onto PrEP following completion of PEPSE.Pre-exposure prophylaxis

Abstract Introduction Men who have sex with men (MSM) and transgender women (TGW) are two key populations (KPs) in Thailand at high risk for HIV. Uptake and scale‐up of pre‐exposure prophylaxis (PrEP) among them has been slow. We used data from Princess PrEP, Thailand’s largest KP‐led PrEP programme, to operationalize PrEP service cascades. We identified gaps and pointed out where additional data are needed to inform a larger HIV prevention cascade. Methods Numbers of people tested for HIV, tested HIV negative, eligible for PrEP (defined as any of the following in the past three months: condomless sex with partners of unknown/uncertain HIV status or antiretroviral treatment or viral load status, multiple partners, engaging in sex work, sexually transmitted infections, injecting drugs, using amphetamine‐type stimulants, or repeated use of post‐exposure prophylaxis), offered PrEP and accepted PrEP during January to November 2019 were retrieved from Princess PrEP database to inform PrEP service cascades for MSM and TGW. Reasons for not accepting PrEP were documented. Results Of 6287 MSM who received HIV testing in Princess PrEP, 92.3% were HIV negative and 70.2% of them were eligible for PrEP. PrEP was offered to 94.7% of those eligible and 48.0% of those offered accepted it. Among 900 TGW who had HIV testing, 95.3% tested HIV negative and 64.8% of them met PrEP eligibility criteria. Of these, 95.0% were offered PrEP and 43.9% of them accepted it. Among MSM and TGW who met PrEP eligibility criteria, no or low‐HIV‐risk perception was the most common reason provided (46.7% of 2007 MSM and 41.9% of 296 TGW) for not accepting PrEP. Conclusions PrEP service cascades from the Princess PrEP programme identified no or low‐risk perception as key barrier to PrEP acceptance among MSM and TGW who met PrEP eligibility criteria. More implementation research studies are needed to explore PrEP motivation and access in larger communities outside of clinical services. This is to identify gaps and strategies to address them within motivation, access and effective use domains of the HIV prevention cascade.

HIV pre-exposure prophylaxis (PrEP) is now available in the UK. However, some men who have sex with men (MSM) continue to use HIV post-exposure prophylaxis following sexual exposure (PEPSE) and are not using PrEP. It is important to characterize MSM having condomless anal sex who are not using PrEP.In a cross-sectional analysis, we compared the characteristics of MSM who used PEPSE in 2021 with MSM using PEPSE in 2017.Overall, 126 MSM used PEPSE in January to June 2017 and 28 MSM used PEPSE in January to June 2021, a 78% decline in PEPSE use. Those MSM using PEPSE in 2021 were significantly younger (27 vs. 35 years, p < 0.01), more likely to identify as black or from another minority ethnic group [29% (8/28) vs. 8% (10/126); p < 0.01], more likely to attend as a result of a group sex encounter [35% (10/28) vs. 16% (10/126); p = 0.03], more likely to attend following sex involving recreational drug use [32% (9/28) vs. 13% (16/126); p = 0.02], and more likely to initiate PEPSE in the emergency department [35% (10/28) vs. 19% (24/126); p = 0.04] compared with MSM attending in 2017. Those MSM using PEPSE in 2021 were significantly less likely to attend follow-up appointments compared with the 2017 cohort [71% (20/28) vs. 87% (110/126); p < 0.05]. Ninety-five per cent of MSM using PEPSE in 2021 were initiated on PrEP at follow-up.Despite PrEP being readily available, some MSM continue using PEPSE and these MSM are significantly more likely to be younger, from black or minority ethnic groups, to engage in group sex involving recreational drugs and to attend the emergency department for PEPSE compared with MSM attending in 2017. Increasing the accessibility of PrEP for this group of MSM is important in order to optimize HIV prevention strategies.

Pre-exposure prophylaxis (PrEP) is currently an important tool for HIV prevention, especially in communities with higher risk of infection, notably men who have sex with men (MSM). To date, PrEP has remained generally unavailable in many cities around the world. In the planning of strategies for PrEP targeting MSM, community assessment is crucial to understand members' responses to the new intervention.Awareness and acceptance are 2 different but intricately linked contexts of PrEP. The aim of this study was to identify the determinants of awareness and acceptance of PrEP among MSM and to delineate their interrelationships in Hong Kong where PrEP services have not been developed.A Web-based questionnaire survey was administered in light of the popularity of the internet as a platform for information and networking in the MSM community. Factors associated with PrEP acceptance and awareness were separately analyzed, and their predictors were subsequently tested by multivariate logistic regression. Associations between acceptance and awareness of PrEP were examined by factor network analysis.Between August and September 2016, results from a total of 453 HIV-negative MSM were analyzed. Half (49.7%, 225/453) of the respondents were aware of PrEP, and 78.3% (355/453) would consider using PrEP when it becomes available. Awareness of PrEP was associated with recent (P=.01) and ongoing (P=.04) use of psychotropic drugs for sex (chemsex). MSM who used online forums to seek sex partners had lower awareness (P=.04) than those visiting physical venues for sex networking. MSM who accepted PrEP were more likely users of internet channels for sex networking (P=.049), especially location-based social network apps (P=.04). MSM accepting PrEP were more concerned about their partners' HIV status (P=.002), history of sexually transmitted infections (P=.01), condom use (P=.02), and HIV testing behavior (P=.02). Multivariate logistic regressions revealed that PrEP awareness was related to one's networking pattern, whereas its acceptance was associated with inclination to self-protect from HIV. Factor network analysis highlighted the importance of chemsex, which was linked by over half of the edges, whereas the rest were contributed by HIV testing behaviors.In Hong Kong, the overall awareness among MSM toward PrEP was only moderate but their acceptance was higher. Targeting MSM with chemsex behaviors through Web-based platforms and parallel development of tailored HIV testing services are important when introducing PrEP in the community.

Abstract Background Oral pre-exposure prophylaxis (PrEP) with tenofovir disoproxil fumarate and emtricitabine (TDF/FTC) has been found to reduce viral acquisition among HIV-negative MSM. This cross-sectional study was conducted before pre-exposure prophylaxis (PrEP) licensure in Israel, and aimed to compare men who have sex with men (MSM) who had heard of PrEP with those who had not, as well as MSM willing to take PrEP with those who were hesitant or not willing to take PrEP. Methods HIV-negative MSM responded anonymously to questionnaires in 2017 regarding their knowledge of and willingness to take PrEP, prior use of PrEP and post-exposure prophylaxis (PEP), and their sexual behaviors. Results Among 1705 participants, 1431 (83.9%) had heard about PrEP. They were older and more often reported being Jewish, having an academic degree, self-identifying as gay/bisexual, being tested for HIV in the last year, participating in group sex, using alcohol or drugs before or during sex, and having prior use of PrEP/PEP compared with MSM who had not heard about PrEP. A total of 760 (44.8%) participants indicated that they would consider taking PrEP, 567 (33.5%) maybe would consider taking PrEP, and 367 (21.7%) would not take PrEP. Those who were willing to take PrEP had a lower level of education, were involved in high-risk sexual behaviors, used alcohol or drugs before or during sex, and had previously used PrEP/PEP compared with participants who maybe would consider taking or would not take PrEP. When participants were asked to indicate if they were willing to take PrEP at different potential efficacies and costs, the willingness to using PrEP increased with the potential efficacy of the drug and adversely related to its cost. Conclusions PrEP awareness was high, and 44.8% indicated willingness to take PrEP, especially those who reported high-risk sexual behaviors. This supports the current policy in Israel to allow PrEP to MSM who are at high-risk. In order to maintain a high level of PrEP-adherence, physicians should consider structural barriers, such as negative stigma of being promiscuous, lack of perceived HIV-risk, difficulties in accessing clinics or paying for PrEP, inability to follow-up or low tolerability of the medication.

In Ireland, men who have sex with men (MSM) have increased HIV risk. Pre-exposure prophylaxis (PrEP), combined with safe sex practices, can reduce HIV acquisition. We estimated MSM numbers likely to present for PrEP by applying French PrEP criteria to Irish MSM behavioural survey data. We adjusted for survey bias, calculated proportions accessing testing services and those likely to take PrEP. We estimated 1-3% of MSM in Ireland were likely to present for PrEP.
