- Abstract
Objectives: We aimed to assess the awareness, willingness to use and use of doxycycline post-exposure prophylaxis (doxyPEP) among men who have sex with men (MSM) and transgender women (TGW) in Belgium. Additionally, we aimed to identify factors associated with doxyPEP use and concerns regarding antimicrobial resistance (AMR)., Methods: Cross-sectional online survey among MSM and TGW in Belgium in April 2024. Participants were recruited through sexual networking applications and social media of community-based organisations. Numerical variables were compared with Wilcoxon rank-sum test and categorical variables with χ
2 or Fisher's exact tests. Factors associated with doxyPEP use were assessed using logistic regression. Willingness to use doxyPEP and concerns about side effects/AMR were assessed before and after presenting a brief paragraph on the potential effects of doxyPEP on AMR., Results: 875 individuals initiated the survey. Almost all identified as men (860/875, 98.3%) with a median age of 40 years (IQR 32-48), 40.4% (n=352/875) had heard of doxyPEP and 9.4% (n=82/875) had used it, among whom the majority used it within the previous 6 months (70/81, 86.4%). In multivariable logistic regression, doxyPEP use was associated with reporting ≥1 sexually transmitted infection (STI) in the previous 12 months, engagement in chemsex, HIV status and pre-exposure prophylaxis use, and education level.About 80% of the participants initially reported being willing to use doxyPEP, and about 50% reported being concerned about side effects. After reading about the potential effects of doxyPEP on AMR, willingness to use decreased to 60% and concerns of side effects/AMR increased to around 70%., Conclusions: Approximately 1 in 10 MSM in Belgium reported using doxyPEP. A recent history of STIs and STI risk factors were positively associated with doxyPEP use. Importantly, concerns about AMR and side effect influenced willingness to use doxyPEP. If doxyPEP is introduced, informing patients about doxyPEP benefits and risks is crucial to enable informed decision-making., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

- Abstract
Background: Since June 2017, oral pre-exposure prophylaxis (PrEP) has been reimbursed in Belgium for people at substantial risk of HIV. To inform the national PrEP programme, we described sociodemographic characteristics of PrEP users, PrEP dispensing practices, testing for HIV and sexually transmitted infections (STIs; gonorrhoea, chlamydia and syphilis), and incidence of HIV and STIs., Methods: Analysis of routinely collected social health insurance claims data from all individuals who were dispensed at least one PrEP prescription between June 2017 and December 2019. Using logistic regression adjusted for age, we examined associations between sociodemographic characteristics and having been dispensed PrEP only once in the first six months of PrEP use., Results: Overall, 4559 individuals were dispensed PrEP. Almost all PrEP users were male (99.2%, 4522/4559), with a median age of 37 years (IQR 30-45). A minority were entitled to an increased healthcare allowance (11.4%, 514/4559). 18% (657/3636) were dispensed PrEP only once in the first six months of PrEP use. PrEP users younger than 25 years, unemployed, entitled to an increased healthcare allowance, and who initiated PrEP between January 2019 and June 2019 were more likely to have had no PrEP dispensing after initiation compared to their counterparts. The testing rates for bacterial STIs and HIV were 4.2 tests per person-year (95% CI 4.1-4.2) and 3.6 tests per person-year (95% CI 3.5-3.6), respectively. Twelve individuals were identified to have seroconverted during the study period, resulting in an HIV incidence rate of 0.21/100 person-years (95% CI 0.12-0.36). The incidence of bacterial STIs was 81.2/100 person-years (95% CI 78.7-83.8)., Conclusions: The study highlights challenges in PrEP persistence and a high incidence of bacterial STIs among individuals receiving PrEP. Tailored prevention support is crucial for individuals with ongoing HIV risk to optimise PrEP effectiveness. Integrated STI testing and prevention interventions within PrEP care are necessary to mitigate STI acquisition and transmission among PrEP users., (© 2024. The Author(s).)

- Abstract
Introduction: In Belgium, oral HIV pre-exposure prophylaxis (PrEP) is primarily provided in specialized clinical settings. Optimal implementation of PrEP services can help to substantially reduce HIV transmission. However, insights into implementation processes, and their complex interactions with local context, are limited. This study examined factors that influence providers' adaptive responses in the implementation of PrEP services in Belgian HIV clinics., Methods: We conducted a qualitative multiple case study on PrEP care implementation in eight HIV clinics. Thirty-six semi-structured interviews were conducted between January 2021 and May 2022 with a purposive sample of PrEP care providers (e.g. physicians, nurses, psychologists), supplemented by 50 hours of observations of healthcare settings and clinical interactions. Field notes from observations and verbatim interview transcripts were thematically analysed guided by a refined iteration of extended Normalisation Process Theory., Results: Implementing PrEP care in a centralized service delivery system required considerable adaptive capacity of providers to balance the increasing workload with an adequate response to PrEP users' individual care needs. As a result, clinic structures were re-organized to allow for more efficient PrEP care processes, compatible with other clinic-level priorities. Providers adapted clinical and policy norms on PrEP care (e.g. related to PrEP prescribing practices and which providers can deliver PrEP services), to flexibly tailor care to individual clients' situations. Interprofessional relationships were reconfigured in line with organizational and clinical adaptations; these included task-shifting from physicians to nurses, leading them to become increasingly trained and specialized in PrEP care. As nurse involvement grew, they adopted a crucial role in responding to PrEP users' non-medical needs (e.g. providing psychosocial support). Moreover, clinicians' growing collaboration with sexologists and psychologists, and interactions with PrEP users' family physician, became crucial in addressing complex psychosocial needs of PrEP clients, while also alleviating the burden of care on busy HIV clinics., Conclusions: Our study in Belgian HIV clinics reveals that the implementation of PrEP care presents a complex-multifaceted-undertaking that requires substantial adaptive work to ensure seamless integration within existing health services. To optimize integration in different settings, policies and guidelines governing PrEP care implementation should allow for sufficient flexibility and tailoring according to respective local health systems., (© 2024 The Author(s).

- Abstract
Background: Guidelines recommend screening for Neisseria gonorrhoeae and Chlamydia trachomatis at three anatomical sites (urethra, anus, and pharynx) every 3 months (3 × 3) in men who have sex with men (MSM) and transgender women taking HIV pre-exposure prophylaxis (PrEP). We present the first randomised controlled trial to compare the effect of screening versus non-screening for N gonorrhoeae and C trachomatis on the incidence of these infections in MSM and transgender women taking PrEP., Methods: A multicentre, randomised, controlled trial of 3 × 3 screening for N gonorrhoeae and C trachomatis versus non-screening was done among MSM and transgender women taking PrEP in five HIV reference centers in Belgium. Participants attended the PrEP clinics quarterly for 12 months. N gonorrhoeae and C trachomatis was tested at each visit in both arms, but results were not provided to the non-screening arm, if asymptomatic. The primary outcome was incidence rate of N gonorrhoeae and C trachomatis infections in each arm, assessed in the per-protocol population. Non-inferiority of the non-screening arm was proven if the upper limit of the 95% CI of the incidence rate ratio (IRR) was lower than 1·25. This trial is registered with ClinicalTrials.gov, NCT04269434, and is completed., Findings: Between Sept 21, 2020, and June 4, 2021, 506 participants were randomly assigned to the 3 × 3 screening arm and 508 to the non-screening arm. The overall incidence rate of N gonorrhoeae and C trachomatis was 0·155 cases per 100 person-days (95% CI 0·128-0·186) in the 3 × 3 screening arm and 0·205 (95% CI 0·171-0·246) in the non-screening arm. The incidence rate was significantly higher in the non-screening arm (IRR 1·318, 95% CI 1·068-1·627). Participants in the non-screening arm had a higher incidence of C trachomatis infections and symptomatic C trachomatis infections. There were no significant differences in N gonorrhoeae infections. Participants in the non-screening arm consumed significantly fewer antimicrobial drugs. No serious adverse events were reported., Interpretation: We failed to show that non-screening for N gonorrhoeae and C trachomatis is non-inferior to 3 × 3 screening in MSM and transgender women taking PrEP in Belgium. However, screening was associated with higher antibiotic consumption and had no effect on the incidence of N gonorrhoeae. Further research is needed to assess the benefits and harms of N gonorrhoeae and C trachomatis screening in this population., Funding: Belgian Health Care Knowledge Centre., Competing Interests: Declaration of interests We declare no competing interests., (Copyright © 2024 Elsevier Ltd.

- Abstract
In Belgium, migrants from Sub-Saharan Africa (SSA) accounted for 45% of new heterosexual HIV infections in 2021, while only 1.5% of PrEP starters were of SSA descent. We explored the acceptance of PrEP and barriers towards PrEP uptake and use among SSA migrant and diaspora communities in Belgium using a participatory action research approach. Trained community researchers (CRs), involved in all phases of the study, co-designed and moderated group discussions (GDs) while simultaneously providing information on HIV and PrEP during workshops. Extensive summaries and field notes were analysed using reflexive thematic analysis. CRs were involved in data analysis, interpretation and reporting. We conducted seven GDs with 51 participants. We identified five major themes: (1) Participants had limited PrEP knowledge, which created feelings of surprise and annoyance about not being informed. This was partly explained by (2) the taboo and stigma that surrounds sexuality and HIV, which could shape PrEP acceptance. (3) Participants shared feelings of otherness due to experiences of racism and discrimination, also in relationship to HIV prevention. (4) PrEP was considered a high-threshold prevention tool, because of its perceived side-effects and its specialized service delivery. (5) Despite nuanced opinions about PrEP, all participants agreed that PrEP promotion should be mainstreamed, so everyone can make an informed decision. In conclusion, PrEP seemed acceptable among our participants. Our qualitative study provides insights into the intersecting barriers to accessing HIV services, showing that SSA diaspora communities are 'hardly reached' rather than 'hard to reach' by PrEP promotion messages., (© 2023.

- Abstract
In Belgium, HIV pre-exposure prophylaxis (PrEP) services are mainly provided through specialised HIV clinics. To optimise PrEP uptake and retention in care, we require insights into users' perspectives on PrEP care. We aimed to elicit experiences with, and preferences for, PrEP service delivery among PrEP users in Belgium, including willingness to involve their family physician (FP) in PrEP care. We adopted a sequential mixed-methods design. We used a web-based longitudinal study among 326 PrEP users that consisted of two questionnaires at six-month intervals, and complemented this with 21 semi-structured interviews (September 2020-January 2022). We conducted descriptive analyses and logistic regression to examine factors associated with willingness to involve their FP in PrEP care. Interviews were analysed using thematic analysis. Survey respondents reported high satisfaction with care received in HIV clinics [median score 9 (IQR 8-10), 10='very satisfied']. Interviews revealed the importance of regular HIV/STI screening, and the expertise and stigma-free environment of HIV clinics. Yet, they also contextualised service delivery barriers reported in the questionnaire, including the burden of cost and challenges integrating PrEP visits into their private and professional lives. Although 63.8% (n = 208/326) of baseline respondents preferred attending an HIV clinic for PrEP follow-up, 51.9% (n = 108/208) of participants in the follow-up questionnaire reported to be willing to have their FP involved in PrEP care. Participants reporting trust in FPs' PrEP and sexual health expertise, or who didn't feel judged by their FP, were more likely to be willing to involve them in PrEP care. Therefore, we recommend a differentiated PrEP service delivery approach, including involving FPs, to make PrEP care more client-centred., (© 2023.

- Abstract
Bimonthly long-acting injectable pre-exposure prophylaxis (LAI-PrEP) can become an important additional tool for HIV prevention among West African men who have sex with men (MSM). The objective was to explore the perceived added value of LAI-PrEP as an HIV prevention tool among MSM in Burkina Faso, Côte d'Ivoire, Mali, and Togo. We conducted eight focus group discussions among 62 HIV-negative MSM between April and May 2021. Participants were recruited via local community-based clinics. Data collection and analysis were guided by grounded theory and community-based participatory approaches. Participants were generally knowledgeable about HIV, and explained particular barriers for HIV prevention in their communities (e.g., denial of HIV). The added value of LAI-PrEP relative to condoms was similar to oral pre-exposure prophylaxis (PrEP) in terms of perceived advantages (e.g., improved sexual satisfaction) or disadvantages (e.g., no protection against other sexually transmitted infections). Compared with oral PrEP, LAI-PrEP was perceived to provide better protection against HIV and to be more convenient (e.g., no need to be mindful of intake and less risk for stigma). Concerns included fear of needles, doubts about efficacy, potential side effects, and difficulties for ensuring timely injections (e.g., when traveling abroad). The results demonstrate that injectable PrEP can be of particular interest to subgroups of West African MSM, although existing HIV prevention tools such as condoms and oral PrEP will remain valuable alongside of, or instead of, LAI-PrEP. Increasing awareness about HIV and tackling discrimination based on sexual orientation continue to be crucial factors to be addressed for HIV prevention.

- Abstract
Introduction: Daily and event-driven oral pre-exposure prophylaxis (PrEP) reduce the risk of HIV acquisition. PrEP use can vary over time, yet little is known about the trajectories of PrEP use irrespective of the chosen PrEP regimens among men who have sex with men (MSM)., Methods: Using data from a mobile, web-based diary application collected daily from 17 August 2015 until 6 May 2018, we analysed PrEP use and sexual behaviour in two large cohorts, AMPrEP (Amsterdam, the Netherlands) and Be-PrEP-ared (Antwerp, Belgium). In both cohorts, participants could choose between daily and event-driven oral PrEP every 3 months. We used group-based trajectory modelling to identify trajectories of PrEP use over time and their determinants. In addition, we estimated the incidence rate of chlamydia, gonorrhoea and syphilis within these trajectories., Results: We included 516 MSM (n = 322 AMPrEP; n = 194 Be-PrEP-ared), of whom 24% chose event-driven PrEP at PrEP initiation. Participants contributed 225,015 days of follow-up (median = 508 days [IQR = 429-511]). Four distinct PrEP use trajectories were identified: ≤2 tablets per week ("low frequency," 12% of the total population), 4 tablets per week ("variable," 17%), "almost daily" (31%) and "always daily" (41%). Compared to participants with "low frequency" PrEP use, participants with "variable" (odds ratio [OR] = 2.18, 95% confidence interval [CI] = 1.04-4.60) and "almost daily" PrEP use were more often AMPrEP participants (OR = 2.64, 95% CI = 1.27-5.49). "Almost daily" PrEP users were more often employed (OR = 6.76, 95% CI = 2.10-21.75) and were younger compared to participants with "low frequency" PrEP use. In addition, the number of days on which anal sex occurred was lower among participants with "low frequency" PrEP use compared to the other groups (all p<0.001). Compared to "low frequency" PrEP users, the incidence rates of chlamydia and gonorrhoea were higher for participants with "almost daily" and "always daily" PrEP use., Conclusions: We uncovered four distinct PrEP use trajectories, pointing to different patterns of PrEP use in practice beyond the two-regimen dichotomy. These trajectories were related to sexual behaviour and rates of sexually transmitted infection. Tailoring PrEP care according to different PrEP use patterns could be an important strategy to improve efficient PrEP delivery., (© 2023 The Authors.

- Abstract
Starting and stopping oral HIV pre-exposure prophylaxis (PrEP) in a way that compromises its effectiveness should be avoided. Between September 2020 and June 2021, we assessed self-perceived and actual knowledge of effectively starting and stopping oral PrEP through an online survey among 206 PrEP users assigned male at birth in Belgium. We examined associations between incorrect start-and-stop knowledge and socio-demographics, sexual behaviour and PrEP use, using bi- and multi-variable logistic regression. The majority of men (84.9%) perceived their start-and-stop knowledge as 'very good', but only 62.1% of all men correctly indicated how to effectively start and stop with PrEP. Using PrEP daily [adjusted OR 2.12, 95% CI (1.06-4.28), p = 0.034] was significantly associated with incorrect start-and-stop knowledge. To enable PrEP users to effectively use PrEP, they need to be better informed about how to start and stop use, irrespective of the dosing regimen., (© 2022.

- Abstract
Background: Tailoring pre-exposure prophylaxis (PrEP) service delivery is key to scaling-up PrEP uptake. Optimal implementation of tailored services requires, among other things, insights into patterns of PrEP use, sexual behaviours and condom use over time., Methods: Between September 2020 and January 2022, we conducted a web-based, longitudinal study among PrEP users in Belgium. In three questionnaire rounds every six-months, we assessed PrEP and condom use, and sex with steady, casual and anonymous partners in the preceding three months. Based on the patterns of PrEP use in the preceding three months, we identified distinct PrEP use categories. We investigated differences in baseline socio-demographics and sexual behaviours by PrEP use category using Fisher's exact and one-way ANOVA tests. Patterns in PrEP and condom use over time were examined using descriptive analyses and visualised in alluvial diagrams., Results: In total, 326 participants completed the baseline questionnaire, and 173 completed all three questionnaires. We identified five distinct PrEP use categories: daily (≥ 90 pills), almost daily (75-89 pills), long period (> 7 consecutive days and < 75 pills) with or without additional short period use, short period (1-7 consecutive days and < 75 pills) and no PrEP use (0 pills). During the study, percentages of individuals in each PrEP use category varied, but did not change significantly over time. At baseline, daily and almost daily users were more likely to report five or more casual sex partners, ten or more anonymous sex partners and anal sex on a weekly basis with casual or anonymous partners compared to those using PrEP for long or short periods. Up to 12.6% (n = 16/127) of participants reporting anal sex with casual or anonymous partners, indicated always using condoms and PrEP with these partners. One in three (n = 23/69) participants who reported anal sex with steady partners had condomless anal sex and did not use PrEP with these partners; with casual or anonymous partners less than 3% reported this., Conclusions: Our findings show that there is little variation in PrEP use over time and that PrEP use was associated with sexual behaviours, which could be taken into account when designing tailored PrEP care., (© 2023.

- Abstract
Introduction: West African men who have sex with men (MSM) remain at substantial risk of contracting HIV. Pre-exposure prophylaxis (PrEP) can be an effective game-changer in reducing the number of HIV infections in MSM communities. To optimize the roll-out of PrEP, we need to better understand how we can increase its uptake. The objective of this study was to explore the perceptions of West African MSM toward PrEP and their proposed strategies to overcome barriers to PrEP uptake within their communities., Methods: Between April 2019 and November 2021, we conducted 12 focus group discussions with 97 MSM not taking PrEP, and 64 semi-structured interviews with MSM taking PrEP, in Burkina Faso, Côte d'Ivoire, Mali, and Togo. Data collection and analysis were guided and conducted by local research teams, enabling a community-based participatory approach. A coordinating researcher collaborated with these local teams to analyze the data guided by a grounded theory approach., Results: The results show that participants were generally positive toward PrEP and that MSM communities have become more aware of PrEP for the study. We identified three main strategies for increasing PrEP uptake. First, participants proposed to raise awareness and improve knowledge of HIV as they considered the self-perceived risk of MSM in their communities to be low. Second, because of existing misconceptions and false information, participants proposed to improve the dissemination of PrEP to allow for informed choices, e.g., via peers or PrEP users themselves. Third, as oral PrEP also entails a risk of being associated with HIV or homosexuality, strategies to avoid stigmatization (e.g., hiding pills) were deemed important., Discussion: These findings indicate that the roll-out of oral PrEP and other future PrEP modalities should be accompanied by raising awareness and improving knowledge on HIV, and wide dissemination of information that focuses on the health-promoting aspect of these tools. Tailored delivery and long-acting PrEP modalities will be important to avoid potential stigmatization. Sustained efforts to prevent discrimination and stigmatization based on HIV status or sexual orientation continue to be highly important strategies to address the HIV epidemic in West Africa., Competing Interests: The Institute of Tropical Medicine received fees from ViiV and GSK for advisory board meetings attended by TR. The remaining authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Reyniers, Babo, Ouedraogo, Kanta, Ekon Agbégnigan, Rojas, Eubanks, Anoma, Dah, Mensah, Dembélé Keita, Spire, Vuylsteke and Laurent.)

- Abstract
Background: PrEP uptake is low among non-Belgian men and transwomen who have sex with men, although the HIV epidemic among men who have sex with men in Belgium is diversifying in terms of nationalities and ethnicity. We lack an in-depth understanding of this gap., Methods: We conducted a qualitative study using a grounded theory approach. The data consists of key informants interviews and in-depth interviews with migrant men or transwomen who have sex with men., Results: We identified four underlying determinants which shape our participants' experiences and contextualize the barriers to PrEP use. These include (1) the intersectional identities of being migrant and men and transwomen who have sex with men, (2) migration related stressors, (3) mental health and (4) socio-economic vulnerability. Identified barriers include: the accessibility of services; availability of information, social resources and providers' attitudes. These barriers influence PrEP acceptance and mediated by individual agency this influences their PrEP uptake., Conclusion: An interplay of several underlying determinants and barriers impacts on PrEP uptake among migrant men and transwomen who have sex with men, illustrating a social gradient in access to PrEP. We need equitable access to the full spectrum of HIV prevention and care for all priority populations, including undocumented migrants. We recommend social and structural conditions that foster exercising these rights, including adapting PrEP service delivery, mental health and social support., (© 2023. The Author(s).)

- Abstract
Incidence rates of sexually transmitted infections (STIs) are rising among men who have sex with men (MSM). Since the rollout of HIV pre-exposure prophylaxis (PrEP), promoting condom use to prevent the spread of STIs has become more challenging. Using a mixed-method design, we explored MSM PrEP users' attitudes toward STIs, condoms, and condom use with nonsteady partners to prevent STIs. We triangulated data from 22 in-depth interviews conducted at a large HIV/STI clinic between August 2021 and January 2022 and an online survey among 326 PrEP users between September 2020 and January 2022. Interviews were analyzed iteratively using a thematic analysis approach. We used bivariate and multi-variate ordered logistic regression to analyze the online survey data. Themes identified in the qualitative data influencing condom use decisions to prevent STIs were as follows: (1) awareness (i.e., perceived severity of and susceptibility to STIs, condom counseling), (2) motivation (i.e., concerns about STIs, sexual pleasure and protection of own health), and (3) perceived social norms and practices (e.g., reduced condom use at community level). Overall, 10.7% of survey respondents consistently used condoms with nonsteady partners. Survey respondents who reported high or moderate levels of willingness to use condoms to prevent acquiring STIs were significantly more likely to use condoms for anal sex with nonsteady partners; those who initiated PrEP 6-12 months ago were less likely to use condoms. We found a wide variation in attitudes toward condom use for the prevention of STIs among MSM using PrEP. We recommend client-centered approaches, taking into account PrEP users' values and priorities toward STI prevention to help reduce the spread of STIs.

- Abstract
Introduction: The number of individuals initiating antiretroviral pre-exposure prophylaxis (PrEP) is increasing, but we do not fully understand who is coming forward for PrEP, how they use it and how they are followed-up. The objective of this study was to examine PrEP user profiles, dynamics in PrEP use and follow-up over time., Methods: We conducted a cohort analysis of longitudinally collected clinical record and questionnaire data among PrEP users at an HIV centre in Antwerp, Belgium, between June 2017 and March 2020. PrEP follow-up and user profiles were examined using descriptive analyses and bivariate logistic regression. We compared early adopting PrEP users (started before June 2018) with late users. We also calculated the probabilities of switching between daily and on-demand PrEP, and interruption, using a naïve estimator., Results and Discussion: We included 1347 PrEP users in the analysis. After 12 months, retention in care was 72.3%. Median time between PrEP visits was 98 days (IQR 85-119 days). At screening visit, early adopting PrEP users (starting June 2017-May 2018) were significantly more likely to report one or more sexually transmitted infection in the prior 12 months, having used drugs during sex, a higher number of sexual partners and a history of paid sex and PrEP use prior to initiation, compared with PrEP users who initiated later (starting June 2018-February 2020). When taking PrEP daily, the probability of staying on daily PrEP at the next visit was 76%, while this was 73% when taking PrEP on-demand. Those using on-demand PrEP had a higher probability (13%) of interrupting PrEP care than daily PrEP users (7%), whereas those returning to PrEP care would mostly re-start with on-demand (35% vs. 13% for daily)., Conclusions: The majority of PrEP users in this sample remained in care after 12 months. The probability of remaining on the same PrEP regimen at the subsequent visit was high. Though, we observed a diversity of transitions between regimens and interruptions in between visits. Our findings reaffirm the need to provide tailored PrEP services, counselling PrEP users across their life course., (© 2022 The Authors.

- Abstract
Since the start of the SARS-CoV-2 pandemic, levels of loneliness have increased among the general population and especially among sexual minorities, such as gay men and other men who have sex with men, who already experienced more problems with social isolation before the pandemic. We analyzed how the disruption of the social network and social support structures by containment measures impact loneliness among gay and other men having sex with men. Our sample consisted of gay and other men having sex with men who had in person communication with family as well as heterosexual friends and homosexual friends before the lockdown (N = 461). Multivariate regression analyses were performed with social provisions (social interaction and reliable alliance) and loneliness as dependent variables. A change from in-person communication with gay peers before the pandemic to remote-only or no communication with gay peers during the pandemic, mediated by change in social integration, was related to an increased feeling of loneliness during the pandemic compared with before the pandemic. There were some unexpected findings, which should be interpreted in the specific social context of the SARS-CoV-2 pandemic. On average, social integration and reliable alliance among MSM increased during the lockdown, even though in-person communication decreased and loneliness increased. Our results show it is critical to maintain a view of social support and social loneliness as lodged within larger social and cultural contexts that ultimately shape the mechanisms behind them.

- Abstract
We examined PrEP awareness, willingness to take it and early PrEP use among men who have sex with men (MSM) at increased risk of HIV acquisition in Belgium. This analysis of the Belgian EMIS online data of 2017-2018 adopts a cascade approach, with the following steps quantified as conditional probabilities: being eligible for, aware of, willing to take PrEP, and PrEP use. One out of three MSM was eligible to use PrEP according to the operationalized Belgian reimbursement criteria. PrEP awareness was lower among socioeconomically vulnerable MSM, MSM living outside large cities, MSM who were less open about their sexuality and those who did not identify as gay or homosexual. A lack of PrEP knowledge, a higher self-efficacy regarding safe sex, having a steady partner and reporting more symptoms of depression were related to unwillingness to use PrEP. Among those willing to take PrEP, less than one third were actually using PrEP. Not using PrEP was associated with living in small cities and experiencing financial problems., (© 2021.

- Abstract
Background: In high income countries, racialized/ethnic minorities are disproportionally affected by COVID-19. Despite the established importance of community involvement in epidemic preparedness, we lack in-depth understanding of these communities' experiences with and responses to COVID-19. We explored information and prevention needs, coping mechanisms with COVID-19 control measures and their impact on lived experiences among selected racialized/ethnic minority communities., Methods: This qualitative rapid assessment conducted in Antwerp/Belgium used an interpretative and participatory approach. We included migrant communities with geographic origins ranging from Sub-Saharan Africa, North-Africa to the Middle East, Orthodox Jewish communities and professional community workers. Data were collected between May 2020-May 2021 through key informant-, in-depth interviews and group discussions (N = 71). Transcripts were analyzed inductively, adopting a reflexive thematic approach. A community advisory board provided feedback throughout the research process., Results: Participants indicated the need for tailored information in terms of language and timing. At the start of the epidemic, they perceived official public health messages as insufficient to reach all community members. Information sources included non-mainstream (social) media and media from home countries, hampering a nuanced understanding of virus transmission mechanisms and local and national protection measures. Participants felt the measures' most negative impact on their livelihoods (e.g. loss of income, disruption of social and immigration support). Economic insecurity triggered chronic stress and fears at individual and family level. High degrees of distrust in authorities and anticipated stigma were grounded in previously experienced racial and ethnic discrimination. Community-based initiatives mitigated this impact, ranging from disseminating translated and tailored information, providing individual support, and successfully reaching community members with complex needs (e.g. the elderly, digitally illiterate people, those with small social networks or irregular legal status)., Conclusion: Study participants' narratives showed how coping with and responding to COVID-19 was strongly intertwined with socio-economic and ethnic/racial characteristics. This justifies conceptualizing COVID-19 a social disease. At the same time, communities demonstrated resilience in responding to these structural vulnerabilities. From a health equity perspective, we provide concrete policy recommendations grounded in insights into communities' structural vulnerabilities and resilience., (© 2022. The Author(s).)

- Abstract
The COVID-19 pandemic most likely had a negative impact on mental health. Sexual minorities are at higher risk for adverse mental outcomes such as depression, anxiety and suicidal ideation. Such mental health disparities may have exacerbated during the COVID-19 pandemic, due to restricted real-life social contact. The study aim was to examine changes in depression, anxiety and suicidal ideation among Belgian sexual minority adults between the periods before and during the first COVID-19 lockdown. We conducted an online survey, which was disseminated by community organizations throughout Belgium in April 2020. The questionnaire included two-item Generalized-Anxiety-Disorder (GAD-2) and Patient-Health-Questionnaire (PHQ-2) measures. To assess how such symptoms and other factors (e.g., loneliness) had changed, we asked to what extent these occurred before and since the lockdown. We included 965 fully completed questionnaires in the analysis. The proportions of participants screening positive for depression and anxiety were significantly higher during the lockdown than before the lockdown, based on their reported symptoms for these periods: 29.3%% vs. 13.5% ( p < 0.001), and 37.1% vs. 25.7% ( p < 0.001) respectively. Lonely and young participants were more likely to acquire depression. About one in five participants reported suicidal ideation. Our findings suggest that the COVID-19 pandemic has exacerbated already existing mental health disparities between sexual minority adults and the general population. These exacerbations may be the result of increased loneliness and social isolation. The results highlight the need for stimulating and strengthening social connectedness within the LGBTQI community during and in the aftermath of the COVID-19 pandemic, and the need for maintaining mental health services for such groups during pandemic restrictions., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Reyniers, Buffel, Thunnissen, Vuylsteke, Siegel, Nöstlinger and Wouters.)

- Abstract
Introduction: In Belgium, the provision of pre-exposure prophylaxis (PrEP) for HIV prevention is centralized in specialized HIV clinics. Engaging family physicians in PrEP care could help scale-up its delivery and reach underserved populations. The objective of this study was to gain insight into family physicians' self-perceived roles in providing PrEP., Methods: We conducted 16 online group discussions with a total of 105 Flemish family physicians, between November 2020 and February 2021. A brief online questionnaire assessed their socio-demographics and experience with sexual health. We analyzed verbatim transcribed data using a grounded theory approach., Results: Despite limited awareness and experience, participants reported a high willingness to be more actively involved in PrEP care. Four potential roles for the family physician in PrEP care were identified: acting as low-threshold entry point for advice; opportunistic case finding of PrEP candidates; initiating appropriate care for PrEP-eligible clients; and ensuring high-quality follow-up care for PrEP users. Participants framed each of these roles within their current activities and responsibilities as primary care providers. Yet, participants differed in their views on the concrete operationalization of these roles, and in the extent of their involvement in PrEP. Particular challenges were a lack of experience with antiretrovirals, perceived limited exposure to clients at high HIV risk, and a lack of expertise and resources to conduct time-intensive risk assessments and counseling related to PrEP., Conclusion: Belgian family physicians demonstrated a keen willingness to be involved in PrEP care, but had differing views on the practical implementation into their practices. Providing tailored training on sexual health and PrEP, and investing in collaboration between primary and secondary care, could optimize the integration of PrEP in the primary care practice., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Vanhamel, Reyniers, Wouters, van Olmen, Vanbaelen, Nöstlinger, Mieghem, Landeghem, Rotsaert, Laga and Vuylsteke.)

- Abstract
Background: Men who have sex with men (MSM) using pre-exposure prophylaxis (PrEP) recurrently infected with STIs are playing a pivotal role in contemporary Sexually transmitted infections (STI) epidemics. Our aim was to assess whether these individuals had more Mycoplasma genitalium ( M. genitalium ) infections and more resistance to macrolides and fluoroquinolones of M. genitalium compared to those who were not recurrently infected with STIs., Methods: The study was performed on 179 Belgian MSM PrEP users that were followed up for 18 months. STIs including M. genitalium were detected quarterly. Detection of resistance-associated mutations (RAMs) to macrolides and fluoroquinolones was performed via Sanger sequencing of the 23S rRNA gene and parC gene (conferring mutations at position 83/87 in ParC). Differences in M. genitalium positivity rate and presence of RAMs between both groups were assessed using mixed-effects logistic regression., Results: A total of 91 new M. genitalium infections were detected among 70 participants. MSM experiencing recurrent STIs have significantly more M. genitalium infections compared to those without (11.7% vs. 4.7% OR: 2.69). Importantly, the prevalence of RAMs to macrolides (95.2% vs. 77.4%) and fluoroquinolones (35.7% vs. 12.9%) was much higher among individuals with recurrent STIs. The difference was only statistically significant for macrolides (OR 5.83, p = .036)., Conclusions: MSM recurrently infected with STIs play a central role in the emergence of antimicrobial resistance in M. genitalium . The use of macrolides and fluoroquinolones should preferably be minimized in this population in order to avoid further emergence of multi-resistant M. genitalium .

- Abstract
Background: Men who have sex with men (MSM) experiencing recurrent sexually transmitted infections (STIs) may play a crucial role in the STI epidemic. However, there is limited understanding of what kind of behavior leads to recurrent STIs., Methods: A total of 179 MSM using preexposure prophylaxis were followed up for 18 months and were screened quarterly for chlamydia, gonorrhea, and syphilis from 2015 to 2018 in Belgium. Participants were stratified into 3 different groups (no STI, one STI episode, recurrent STI episodes during the study). Sociodemographic and sexual behavioral characteristics were compared between the 3 groups, and significant associations with recurrent STI were explored using multivariate logistic regression models., Results: A total of 62.0% (n = 111/179) of participants experienced at least one STI during the study, and more than 1 in 3 became reinfected with an STI at another visit (n = 66/179 [36.9%]). Participants experiencing recurrent STIs reported the highest frequency of sexualized drug use (86.4%) compared with participants experiencing one (60.0%) or no STI (47.1%). Therefore, sexualized drug use was highly associated with recurrent STIs (adjusted odds ratio [aOR]. 4.35). Other factors associated with recurrent STIs were being younger than 40 years (aOR, 3.29), had a high number (>4) of nonsteady partners with whom receptive (aOR, 1.17) or insertive (aOR, 1.12) condomless anal intercourse occurred in the last 3 months., Conclusions: Sexualized drug use was the greatest risk factor for having recurrent STIs. Tailoring prevention and care, including specialized services tackling problematic drug use in a sexual context, may help to curb the STI epidemic among MSM., Competing Interests: Conflict of Interest and Sources of Funding: The authors do not have any conflicts of interest.

- Abstract
Objectives: To examine changes in the occurrence of physical sex with non-steady partners among men who have sex with men (MSM) in Belgium during the first weeks of the COVID-19 lockdown and associations with sociodemographic factors, sexual practices, drug, alcohol and pre-exposure prophylaxis (PrEP) use. A secondary objective was to explore changes in PrEP use and the need for PrEP follow-up., Methods: A cross-sectional online survey. The questionnaire was available in Dutch, French and English, between April 10 and 27 (2020), and disseminated via sexual health and lesbian, gay, bisexual, trans, queer or intersex organisations throughout Belgium. Eligibility criteria included being 18 years or older, not being exclusively heterosexual and living or being born in Belgium., Results: The sample included 694 MSM. Physical sex with non-steady partners decreased from 59.1% to 8.9% during the first weeks of the lockdown. Those who had sex with non-steady partners were significantly more likely to be HIV positive, to use PrEP or to have engaged in sexual practices such as group sex, chemsex and sex work before the lockdown, compared with their counterparts. Among those who used PrEP before the lockdown, 47.0% stopped using PrEP, 19.7% used event-driven PrEP and 33.3% used daily PrEP during the lockdown. Almost two-thirds of PrEP users had a PrEP care appointment in the weeks before the lockdown and a minority received follow-up elsewhere or online. Some PrEP users had concerns regarding their follow-up., Conclusions: MSM in our survey substantially reduced sexual contact with non-steady partners during the first weeks of the COVID-19 lockdown, suggesting that the risk for HIV and STI transmission in this period was low. We recommend ensuring access to sexual health services, such as HIV testing and follow-up for PrEP for the small group having multiple sex partners and engaging in sexual practices such as chemsex, or group sex, even in times of a pandemic threat., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

- Abstract
Background: Pre-exposure prophylaxis (PrEP) efficacy for HIV prevention is highly correlated with the degree of adherence. The objective of this analysis was to identify PrEP users who did not correctly take their dose in high HIV exposure situations and to explore potential predictors of this behavior., Methods: Study participants completed a personal Web-based diary during their entire follow-up, providing daily information on pill intake and sexual activity. They also completed a sociobehavioral questionnaire. The association between the number of unprotected high HIV exposure sex days (as a measure for suboptimal adherence) and potential predicting factors was examined using a logistic regression, followed by a negative binomial regression model. We also constructed a risk index score for predicting poor adherence., Results: A total of 40.8% of participants did not correctly use PrEP in at least one situation of high HIV exposure during follow-up. Not having a HIV-negative steady partner, reporting more than 10 occasional or more than 10 anonymous partners, using chemsex drugs, receiving money for sex, and a history of more than one sexually transmitted infection were significantly associated with unprotected high HIV exposure sex. The risk index score yielded a poor discriminative power (area under the curve 0.62 and 0.64)., Conclusions: We observed a high proportion of suboptimal adherence. Even if none of the participants acquired HIV during the study, tailored adherence support is needed to specific men who have sex with men such as those taking chemsex drugs and those engaging in paid sex., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2021 Wolters Kluwer Health, Inc.

- Abstract
Introduction: This study produces an estimate of the proportion of eligible PrEP users among people of Sub-Saharan African background based on the Belgian PrEP eligibility criteria and examines associations with socio-economic and demographic characteristics., Methods: We performed logistic regression analysis on data of a representative community-based survey conducted among Sub-Saharan African communities (n = 685) living in Antwerp., Results: Almost a third (30.3%) of the respondents were eligible to use PrEP. Those who were male, single, lower educated, undocumented, and had experienced forced sex were more likely to be eligible for PrEP use. The findings highlight the importance of taking intra-, interpersonal and structural HIV risk factors into account., Conclusions: The study shows high unmet PrEP needs in this population, especially among those with high vulnerability for HIV acquisition. A better understanding of barriers to PrEP use in this population group is needed to allow for equitable access., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Introduction: Daily and event-driven PrEP are both efficacious in reducing the risk for HIV infection. However, the practice of event-driven PrEP (edPrEP) is less well studied, in particular when provided as an alternative to daily PrEP. We studied regimen preferences and switches, and sexually transmitted infection (STI) incidence., Methods: We analysed pooled data from two prospective cohort studies among MSM: Be-PrEP-ared, Belgium and AMPrEP, the Netherlands. In both projects, participants could choose between daily and edPrEP at three-monthly study visits, when they were also screened for sexually transmitted infections including hepatitis C (HCV). We assessed the proportion choosing each regimen, and the determinants of choosing edPrEP at baseline. Additionally, we compared the incidence rates (IRs) of HCV, syphilis and chlamydia or gonorrhoea between regimens using Poisson regression. The study period was from 3 August 2015 until 24 September 2018., Results and Discussion: We included 571 MSM, of whom 148 (25.9%) chose edPrEP at baseline. 31.7% of participants switched regimen at least once. After 28 months, 23.5% used edPrEP. Older participants (adjusted odds ratio (aOR) = 1.38 per 10 years, 95% confidence interval (CI) = 1.15 to 1.64) and those unemployed (aOR = 1.68, 95% CI = 1.03 to 1.75) were more likely to initially choose edPrEP. IR of HCV and syphilis did not differ between regimens, but the IR of chlamydia/gonorrhoea was higher among daily users (adjusted incidence rate ratio = 1.61, 95% CI = 1.35 to 1.94)., Conclusions: A quarter of participants chose edPrEP at baseline and at 28 months this proportion was similar. Although the IR of HCV and syphilis were similar in the two regimens, the lower incidence of chlamydia and gonorrhoea among edPrEP users may suggest that less frequent STI testing of this group could be considered., (© 2021 The Authors.

- Abstract
Pre-Exposure Prophylaxis (PrEP) is a novel HIV prevention tool. PrEP stigma is a frequently reported barrier, while social disclosure of PrEP use may be an important facilitator. We explored how PrEP users managed PrEP use disclosure using a symbolic interactionist approach. We interviewed 32 participants from two PrEP demonstration projects (Be-PrEP-ared, Antwerp; AMPrEP, Amsterdam). We validated qualitative findings through Be-PrEP-ared questionnaire data. A minority of participants had received negative reactions on PrEP. The way PrEP use was disclosed was highly dependent on the social situation. In a sexual context among MSM, PrEP use was associated with condomless sex. Friends endorsed PrEP use as a healthy choice, but also related it to carelessness and promiscuity. It was seldom disclosed to colleagues and family, which is mostly related to social norms dictating when it is acceptable to talk about sex. The study findings reveal that PrEP stigma experiences were not frequent in this population, and that PrEP users actively manage disclosure of their PrEP user status. Frequent disclosure and increased use may have helped PrEP becoming normalised in these MSM communities. To increase uptake, peer communication, community activism and framing PrEP as health promotion rather than a risk-reduction intervention may be crucial., (© 2021 Foundation for the Sociology of Health & Illness.)

- Abstract
Pre-exposure prophylaxis (PrEP) is a promising strategy to reduce HIV incidence among men who have sex with men (MSM). How and when PrEP is used could in part be influenced by its impact on the sexual well-being of its users. Yet, the impact of PrEP on sexual well-being has received little attention in current literature and is not well-understood. We conducted 43 in-depth interviews (June 2017-June 2018) with HIV-negative MSM who started PrEP within the Amsterdam PrEP study. We used purposive sampling to select participants who (1) reported changes on well-being indicators; (2) switched between PrEP-dosing regimens; (3) neither changed regimens nor changed on well-being indicators. Transcribed interviews were qualitatively analyzed by means of an open-coding process. Results showed that PrEP minimized HIV-related fear, increased self-esteem, and reduced stigma and shame about having condomless anal sex. The psychological relief provided by PrEP also enabled relaxation which reduced pain during anal sex. PrEP use increased the diversity of partner choices and improved the perceived quality of sexual relationships and the ability to develop relationships. Along with this positive impact, almost half of interviewees reported concurrent negative experiences. In some cases, PrEP triggered more extreme sexual behaviors and/or problematic increases in preoccupation with sex and drug use. These were perceived as having a negative impact on sexual relationships, sexual well-being, PrEP adherence, and general health. In conclusion, our findings suggest that PrEP contributes to improvements in sexual well-being that go beyond protection from HIV. Counseling strategies should be devised to help PrEP users mitigate possible co-existing negative consequences of PrEP use.

- Abstract
Background: Bacterial sexually transmitted infections (STIs) are highly prevalent among men who have sex with men who use HIV pre-exposure prophylaxis (PrEP), which leads to antimicrobial consumption linked to the emergence of antimicrobial resistance. We aimed to assess use of an antiseptic mouthwash as an antibiotic sparing approach to prevent STIs., Methods: We invited people using PrEP who had an STI in the past 24 months to participate in this single-centre, randomised, double-blind, placebo-controlled, AB/BA crossover superiority trial at the Institute of Tropical Medicine in Antwerp, Belgium. Using block randomisation (block size eight), participants were assigned (1:1) to first receive Listerine Cool Mint or a placebo mouthwash. They were required to use the study mouthwashes daily and before and after sex for 3 months each and to ask their sexual partners to use the mouthwash before and after sex. Participants were screened every 3 months for syphilis, chlamydia, and gonorrhoea at the oropharynx, anorectum, and urethra. The primary outcome was combined incidence of these STIs during each 3-month period, assessed in the intention-to-treat population, which included all participants who completed at least the first 3-month period. Safety was assessed as a secondary outcome. This trial is registered with Clinicaltrials.gov, NCT03881007., Findings: Between April 2, 2019, and March 13, 2020, 343 participants were enrolled: 172 in the Listerine followed by placebo (Listerine-placebo) group and 171 in the placebo followed by Listerine (placebo-Listerine) group. The trial was terminated prematurely because of the COVID-19 pandemic. 151 participants completed the entire study, and 89 completed only the first 3-month period. 31 participants withdrew consent, ten were lost to follow-up, and one acquired HIV. In the Listerine-placebo group, the STI incidence rate was 140·4 per 100 person-years during the Listerine period, and 102·6 per 100 person-years during the placebo period. In the placebo-Listerine arm, the STI incidence rate was 133·9 per 100 person-years during the placebo period, and 147·5 per 100 person-years during the Listerine period. We did not find that Listerine significantly reduced STI incidence (IRR 1·17, 95% CI 0·84-1·64). Numbers of adverse events were not significantly higher than at baseline and were similar while using Listerine and placebo. Four serious adverse events (one HIV-infection, one severe depression, one Ludwig's angina, and one testicular carcinoma) were not considered to be related to use of mouthwash., Interpretation: Our findings do not support the use of Listerine Cool Mint as a way to prevent STI acquisition among high-risk populations., Funding: Belgian Research Foundation - Flanders (FWO 121·00)., (Copyright © 2021 Elsevier Ltd.

- Abstract
Background: The importance of community involvement in the response against disease outbreaks has been well established. However, we lack insights into local communities' experiences in coping with the current COVID-19 pandemic. This study explored both the impact of, and response to, COVID-19 within the Orthodox Jewish communities of Antwerp (Belgium) during the first lockdown period (March 2020 - May 2020)., Methods: We conducted an explorative qualitative study using a participatory approach. First, we performed a community mapping to identify relevant stakeholders. Through the active involvement of a community advisory board and based on qualitative interviews with key-informants and community members, we elicited lived experiences, attitudes, and perceptions towards COVID-19. Interviews were conducted both face-to-face and using online web conferencing technology. Data were analyzed inductively according to the principles of thematic analysis., Results: Government-issued outbreak control measures presented context-specific challenges to the Orthodox Jewish communities in Antwerp. They related mainly to the remote organization of religious life, and practicing physical distancing in socially and culturally strongly connected communities. Existing community resources were rapidly mobilized to adapt to the outbreak and to self-organize response initiatives within communities. The active involvement of community and religious leaders in risk communication proved to be of great importance to facilitate the coverage and uptake of pandemic control measures while protecting essential community values and traditions. Creating bottom-up and community-adapted communication strategies, including addressing language barriers and involving Rabbis in the dissemination of prevention messages, fostered a feeling of trust in government's response measures. However, unmet information and prevention needs were also identified, such as the need for inclusive communication by public authorities and the need to mitigate the negative effects of stigmatization., Conclusion: The experiences of Orthodox Jewish communities in Antwerp demonstrate a valuable example of a feasible community-centered approach to health emergencies. Increasing the engagement of communities in local decision-making and governance structures remains a key strategy to respond to unmet information and prevention needs.

- Abstract
There is a need for an in-depth understanding of the impact of PrEP on users' sexual health and behaviour, beyond the focus on 'risk'. This mixed-method study was part of a Belgian PrEP demonstration project following 200 men who have sex with men (MSM) for at least 18 months. Taking a grounded-theory approach, 22 participants were interviewed and their transcripts analysed. The preliminary analysis guided the analysis of the questionnaire data. Overall, PrEP improved sexual health. Participants felt better protected against HIV, which enabled them to change their sexual behaviour. The reduction in condom use was moderated by interviewees' attitudes towards the risk for other STIs. Other changes included having more anal sex and experimentation with new sexual behaviours. While PrEP empowers MSM in taking care of their sexual health, comprehensive sexual health counselling is crucial to provide care for users who feel less in control over their sexual health.

- Abstract
Background: Strengthening HIV prevention is imperative given the continued high HIV incidence worldwide. The introduction of oral PrEP as a new biomedical HIV prevention tool can be a potential game changer because of its high clinical efficacy and the feasibility of its provision to different key populations. Documenting the existing experience with PrEP service delivery in a variety of real-world settings will inform how its uptake and usage can be maximised., Methods: We conducted a scoping review using the five-step framework provided by Arksey and O'Malley. We systematically searched the existing peer-reviewed international and grey literature describing the implementation of real-world PrEP service delivery models reporting on four key components: the target population of PrEP services, the setting where PrEP was delivered, PrEP providers' professionalisation and PrEP delivery channels. We restricted our search to English language articles. No geographical or time restrictions were set., Results: This review included 33 articles for charting and analysing of the results. The identified service delivery models showed that PrEP services mainly targeted people at high risk of HIV acquisition, with some models targeting specific key populations, mainly men who have sex with men. PrEP was often delivered centralised and in a clinical or hospital setting. Yet also community-based as well as home-based PrEP delivery models were reported. Providers of PrEP were mainly clinically trained health professionals, but in some rare cases community workers and lay providers also delivered PrEP. In general, in-person visits were used to deliver PrEP. More innovative digital options using mHealth and telemedicine approaches to deliver specific parts of PrEP services are currently being applied in a minority of the service delivery models in mainly high-resource settings., Conclusions: A range of possible combinations was found between all four components of PrEP service delivery models. This reflects differentiation of care according to different contextual settings. More research is needed on how integration of services in these contexts could be expanded and optimised to respond to key populations with unmet HIV prevention needs in different settings.

- Abstract
Little is known about how interacting psychosocial problems may influence sexual behaviour among men having sex with men taking Pre-exposure prophylaxis (PrEP). This study assessed (1) the prevalence of depression, recreational drug-use and sexual risk behaviour; (2) changes in these psychosocial conditions over time; and (3) the interaction of drug use and depression with sexual risk behaviour. We analysed data of the Belgian Be-PrEP-ared cohort study ( N = 200). We assessed depression using the PHQ-9, recreational drug use and receptive condomless anal intercourse (rCAI) with anonymous partners. Frequencies of psychosocial problems were compared at baseline, 9 and 18 months follow-up (FU). Bivariate associations between depression and drug-use behaviour, and their interaction with rCAI with anonymous sexual partners using was examined using linear regression. Receptive CAI increased from 41% at baseline to 53% at M18 ( p = 0.038). At baseline, we found an interaction effect of poly-drug use and depression, potentiating rCAI with anonymous partners. Participants reporting poly-drug use associated with depression were significant more likely to report this type of sexual risk behaviour than those who did not report this association ( p = 0.030). The high level of intertwined psychosocial problems call for multi-level interventions for those PrEP users experiencing a syndemic burden.

- Abstract
Men who have sex with men (MSM) are at high risk for acquiring HIV in Belgium. This study explores MSMs' hypothetical willingness to use pre-exposure prophylaxis (PrEP), assesses it against formal PrEP eligibility criteria, and identifies factors associated with incongruence between eligibility and willingness. We used data from an online survey of n = 1444 self-reported HIV-negative MSM. Participants were recruited through social media of MSM organizations and dating apps. Univariate analysis described PrEP willingness and eligibility; bivariate analyses examined how specific co-variates (socio-demographic, knowledge-related, and attitudinal and behavioral factors) were associated with eligibility and willingness. About 44% were eligible for PrEP and about 70% were willing to use it. Those who were eligible were significantly more likely be willing to take PrEP ( p < 0.001). Two incongruent groups emerged: 16% of eligible participants were unwilling and 58% of ineligible participants were willing to use PrEP. Factors associated with this incongruence were sexual risk behavior, HIV risk perception, partner status, PrEP knowledge, and attitudinal factors. Because the two groups differ in terms of profiles, it is important to tailor HIV prevention and sexual health promotion to their needs. Among those at risk but not willing to take PrEP, misconceptions about PrEP, and adequate risk perception should be addressed., Competing Interests: The authors declare no conflict of interest. The sponsors had no role in the design, execution, interpretation, or writing of the study.

- Abstract
Introduction: Pre-Exposure Prophylaxis (PrEP) is highly effective in reducing the risk for HIV infection among men who have sex with men (MSM) and may have an important impact in slowing down the HIV epidemic. Concerns remain however about low adherence, increased risk behaviour and reduced condom use when using PrEP. The aim of this study was to assess these factors prospectively among MSM using daily and event-driven PrEP in Belgium., Methods: An open-label prospective cohort study was conducted from October 2017 to May 2018 at the Institute of Tropical Medicine, in Antwerp, Belgium. At enrolment, MSM at high risk for HIV chose between daily or event-driven PrEP. They were allowed to switch regimens or stop taking PrEP at each of their tri-monthly visits. Data were collected on an electronic case report form, web-based diary and self-administered questionnaire. Screening for HIV and other Sexually Transmitted Infections (STIs) was also performed., Results: Two hundred MSM were followed up for a total duration of 318 person-years. At month 18, 75.4% of the participants were on daily and 24.6% were on event-driven PrEP. The mean proportion of covered sex acts by PrEP for the complete follow-up period was 91.5% for all participants, 96.5% for daily and 67.0% for event-driven PrEP use. The number of casual and anonymous sex partners was significantly higher for daily users, as compared with event-driven users, but did not change over time. In contrast, the mean proportion of condomless receptive anal intercourse with casual and anonymous partners increased significantly during follow-up, for both daily and event-driven use (p < 0.0001 for all 4 trends). No new HIV infection was diagnosed during follow-up. The incidence of bacterial STIs was 75.4 per 100 person-years (95% CI 63.8 to 89.1). We did not detect a significant change in N. gonorrhoeae/C. trachomatis incidence over time. The incidence of hepatitis C was 2.9 per 100 person-years., Conclusions: PrEP is an effective and well adopted HIV prevention tool for MSM in Belgium. Participants adapted daily and event-driven regimens to their own needs and were able to adapt their PrEP adherence to risk exposure., (© 2019 The Authors.

- Abstract
Objectives: Pre-exposure prophylaxis (PrEP) users are screened bi-annual for sexually transmitted infections (STIs). A novel device, called the Colli-Pee, collects first-void urine in a standardised way and the collector tube can be easily delivered by regular post to a certified laboratory. The aim of the study was a one-to-one comparison between the STI test results obtained with the urine collected in the clinic, versus urine collected at home in a real-life setting by Men who have Sex with Men (MSM) in Belgium. The user-friendliness and acceptability of the Colli-Pee device by the users was also evaluated., Design: A single-site nested substudy in a prospective PrEP demonstration project (Be-PrEP-ared) among MSM in Belgium., Participants: A total of 473 home-based samples from 213 MSM were received with a mean age of 38.5 years., Interventions: Participants were requested to collect a urine sample at home using the Colli-Pee device and to send it to the laboratory via regular mail., Primary and Secondary Outcome Measures: The presence of Chlamydia trachomatis (CT) , Neisseria gonorrhoeae (NG) , Mycoplasma genitalium (MG) and Trichomonas vaginalis (TV) was determined using molecular amplification assays. Agreement between test results of samples collected at the clinic and collected at home were evaluated using Cohen's kappa statistic., Results: TV was not detected. A very good to almost perfect agreement was found for CT, NG and MG of κ=0.75, 0.87 and 0.85, respectively. Using the Colli-Pee device only one low positive CT and two MG infections were missed, however, three additional CT, two NG and six MG infections were detected., Conclusions: The Colli-Pee device is a feasible and convenient way to collect urine at home for STI testing. This may be particularly relevant for populations that need frequent STI testing, such as PrEP users and patients who prefer home-sampling., Trial Registration Number: NCT02552914; Pre-results., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

- Abstract
Background Since 1 June 2017, oral pre-exposure prophylaxis (PrEP) could be prescribed and reimbursed in Belgium as prophylactic medication for people who are at increased risk of HIV acquisition. The aim of this study was to determine the uptake of daily and event-driven PrEP in Belgium during the first 9 months of roll-out., Methods: Routine aggregated data on the number of reimbursement requests and the number of boxes of Truvada (Gilead Sciences, Cambridge, UK) delivered for PrEP through the Belgian pharmacies were obtained from the National Institute for Health and Disability Insurance. We also collected aggregated data from seven Aids Reference Centres (ARCs) currently providing most of the PrEP care in Belgium., Results: From 1 June 2017 to 28 February 2018, 1352 requests for reimbursement were approved by the National Institute for Health and Disability Insurance. Almost 98% of those who bought at least one box of 30 tablets of emtricitabine 200mg/tenofovir disoproxil fumarate 300mg (FTC/TDF) in a Belgian pharmacy were male, and most (67%) were between 30 and 50 years of age. According to data obtained from ARCs, the proportion of those choosing event-driven PrEP initially ranged between 29% and 73%., Conclusions: The uptake of PrEP in Belgium since the start of the roll-out in June 2017 has been high, and almost entirely limited to men who have sex with men, of whom 43% initially prefer a non-daily regimen. A better understanding is needed as to why other populations, such as sub-Saharan African migrants, are not accessing PrEP, as well as the development of a more sustainable PrEP delivery model.

- Abstract
Background Physicians have a crucial role in the implementation and scale up of pre-exposure prophylaxis (PrEP). The objective of this study is to examine Belgian physicians' PrEP knowledge, concerns, acceptance and their willingness to prescribe PrEP., Methods: A cross-sectional online survey was conducted between March and June 2016. Dissemination targeted Belgian primary care physicians (PCPs) and HIV specialists. Sociodemographic characteristics, experience with HIV and PrEP, self-assessed PrEP knowledge, concerns about PrEP, and PrEP acceptance were stratified according to professional background. Associations with willingness to prescribe PrEP were examined using univariable and multivariable binary logistic regression analyses., Results: In total, 333 completed surveys were included in the analysis. Sixty-two physicians (18.6%) scored their knowledge of PrEP to be good, 263 (79.0%) had an accepting attitude towards PrEP and 198 (59.5%) were willing to prescribe PrEP if approved in Belgium. HIV specialists consistently reported having better knowledge of PrEP, less concerns and a more accepting attitude towards PrEP than PCPs. In multivariable logistic regression analysis, higher PrEP knowledge (OR 2.4; 95%CI: 1.0-5.7) and higher PrEP acceptance (OR: 3.8; 95%CI: 2.1-6.8) remained significantly associated with the willingness to prescribe PrEP., Conclusions: HIV specialists are better prepared to provide PrEP than PCPs in Belgium. Interventions to improve PrEP knowledge and acceptance among all providers are needed. The role of PCPs could be very important in optimising the rollout of PrEP, but additional training and guidelines will be needed.

Background: Daily pre-exposure prophylaxis and event-driven pre-exposure prophylaxis (PrEP) are efficacious in reducing HIV transmission among men who have sex with men (MSM). We analyzed baseline data from a PrEP demonstration project "Be-PrEP-ared" in Antwerp, Belgium, to understand preferences for daily PrEP or event-driven PrEP among MSM at high risk of HIV and factors influencing their initial choice., Methods: Cross-sectional data from an open-label prospective cohort study, using mixed methods. Participants who preregistered online were screened for eligibility and tested for sexually transmitted infections (STIs). Eligible participants chose between daily PrEP and event-driven PrEP and reported on behavioral data through an electronic questionnaire. In-depth interviews were conducted with a selected subsample. Bivariate associations were examined between preferred PrEP regimens and sociodemographic factors, sexual behavior, and STIs at screening., Results: In total, 200 participants were enrolled between October 2015 and December 2016. Self-reported levels of sexual risk-taking before enrollment were high. STI screening revealed that 39.5% had at least 1 bacterial STI. At baseline, 76.5% of participants preferred daily PrEP and 23.5% event-driven PrEP. Feeling able to anticipate HIV risk was the most frequent reason for preferring event-driven PrEP. Regimen choice was associated with sexual risk-taking behavior in the past 3 months. Almost all participants (95.7%) considered it likely that they would change their dosing regimen the following year., Conclusion: Event-driven PrEP was preferred by 23.5% of the participants, which better suits their preventive needs. Event-driven PrEP should be included in PrEP provision as a valuable alternative to daily PrEP for MSM at high risk of HIV.

- Abstract
In many Western countries with good coverage of antiretroviral treatment (ART) programmes the annual number of HIV infections is still high and not (yet) declining among men who have sex with men (MSM). This might indicate that antiretroviral treatment roll-out alone will not turn around the course of the epidemic and that new, additional tools are needed. Antiretrovirals used as prevention tools for people not yet infected with HIV, such as pre-exposure prophylaxis (PrEP) could be such important additional tools. PrEP is a new type of biomedical prevention, which involves the use of antiretrovirals before, during and after (periods of) sexual exposure to HIV. In this review, we will focus on PrEP as a new prevention tool for MSM at high risk in Europe, including its evidence for effectiveness, challenges for implementation, ongoing European demonstration studies; as well as how PrEP relates to other existing prevention tools. In light of European Medicines Agency's recent recommendation for approval of PrEP we briefly review the potential implications., Competing Interests: Competing interests: None declared., (Published by the BMJ Publishing Group Limited.

- Abstract
Background: Although the acute hospital setting is not considered to be an ideal place of death, many people are admitted to hospital at the end of life., Aim: To examine what proportion of terminal hospital admissions among their patients family physicians consider to have been avoidable and/or inappropriate; which patient, family physician and admission factors are associated with the perceived inappropriateness or avoidability of terminal hospital admissions; and which interventions could have prevented them, from the perspective of family physicians., Design: Survey among family physicians, linked to medical record data., Setting: Patients who had died non-suddenly in the acute hospital setting of a university hospital in Belgium between January and August 2014., Results: We received 245 completed questionnaires (response rate 70%) and 77% of those hospital deaths ( n = 189) were considered to be non-sudden. Almost 14% of all terminal hospital admissions were considered to be potentially inappropriate, almost 14% potentially avoidable and 8% both, according to family physicians. The terminal hospital admission was more likely to be considered potentially inappropriate or potentially avoidable for patients who had died of cancer, when the patient's life expectancy at the time of admission was limited, by family physicians who had had palliative care training at basic, postgraduate or post-academic level, and when the admission was initiated by the patient, partner or other family., Conclusion: Timely communication with the patient about their limited life expectancy and the provision of better support to family caregivers may be important strategies in reducing the number of hospital deaths.
