RESUMO

OBJECTIVE: The available epidemiological and clinical evidence from the currently ongoing monkeypox (MPX) outbreak in non-endemic areas suggests an important factor of sexual transmission. However, limited information on the behaviour and experiences of individuals with an MPX infection has to date been provided. We aimed to describe the initial phase of the MPX outbreak in Belgium, and to provide a more in-depth description of sexual behaviour and transmission contexts. METHODS: We used routine national surveillance data of 139 confirmed MPX cases with date of symptom onset until 19 June 2022, complemented with 12 semistructured interviews conducted with a subsample of these cases. RESULTS: Sexualised environments, including large festivals and cruising venues for gay men, were the suspected exposure setting for the majority of the cases in the early outbreak phase. In-depth narratives of sexual behaviour support the hypothesis of MPX transmission through close physical contact during sex. Despite awareness of the ongoing MPX outbreak, low self-perceived risk of MPX acquisition and confusing initial signs and symptoms for other STIs or skin conditions delayed early detection of an MPX infection. In addition, we describe relevant contextual factors beyond individual behaviour, related to sexual networks, interpersonal interactions and health systems. Some of these factors may complicate early MPX detection and control efforts. CONCLUSION: Our results highlight the role of sexual contact and networks in the transmission of MPX during the early phase of the outbreak in Belgium. Risk communication messages should consistently and transparently state the predominant sexual transmission potential of MPX virus, and prevention and control measures must be adapted to reflect multilevel factors contributing to MPX transmission risk.

RESUMO

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.

RESUMO

Several countries in the European Union (EU) and European Economic Area (EEA) established and/or scaled up HIV pre-exposure prophylaxis (PrEP) programmes between 2016 and 2023. Data on PrEP programmes' performance and effectiveness in reaching those most in need will be needed to assess regional progress in the roll-out of PrEP. However, there is a lack of commonly defined indicators for routine monitoring to allow for minimum comparability. We propose a harmonised PrEP monitoring approach for the EU/EEA, based on a systematic and evidence-informed consensus-building process involving a broad and multidisciplinary expert panel. We present a set of indicators, structured along relevant steps of an adapted PrEP care continuum, and offer a prioritisation based on the degree of consensus among the expert panel. We distinguish between 'core' indicators deemed essential for any PrEP programme in the EU/EEA, vs 'supplementary' and 'optional' indicators that provide meaningful data, yet where experts evaluated their feasibility for data collection and reporting as very context-dependent. By combining a standardised approach with strategic opportunities for adaptation and complementary research, this monitoring framework will contribute to assess the impact of PrEP on the HIV epidemic in Europe.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

Understanding the pathways that expose women to HIV transmission are vital in improving HIV prevention, especially among a "hidden" group of women without pre-established known risk for HIV. We investigated the pathways which place certain women at greater risk for HIV in a qualitative exploratory study with theoretical sampling using an emergent theory study design in an urban setting in Indonesia. We conducted semi-structured interviews with 47 HIV-infected women, one focus group discussion with five young women who occassionally engage in sex work, participant observation at six sex work venues and two midwife clinics, and 11 informal interviews with midwives, nurses, and obstetricians. Our research found that many women not characterized as belonging to a "high-risk group" or "key population" were nevertheless at increased risk for HIV. A history of sexual abuse, premarital sex, divorce, or involvement in sex work, often precipitated by poverty coupled with discriminatory public health policies further heightened women's exposure to HIV. While reaching at-risk populations is a key strategy in HIV prevention, a novel and more tailored approach is needed to reach more hidden categories of women with less apparent risk behavior yet considerable risk for HIV infection.

RESUMO

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.

RESUMO

To evaluate the effect of physical distancing and school reopening in Brussels between August and November 2020, we monitored changes in the number of reported contacts per SARS-CoV-2 case and associated SARS-CoV-2 transmission. The second COVID-19 pandemic wave in Brussels was the result of increased social contact across all ages following school reopening. Physical distancing measures including closure of bars and restaurants, and limiting close contacts, while primary and secondary schools remained open, reduced social mixing and controlled SARS-CoV-2 transmission.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: An unprecedented epidemic of Ebola virus disease (EVD) affected Guinea in 2014 and 2015. It weakened the already fragile Guinean health system. This study aimed to assess the effects of the outbreak on Prevention of Mother-to-Child Transmission of HIV (PMTCT) services in 2014. METHODS: We conducted a cross-sectional retrospective study. Data was collected from 60 public health centers (30 in the EVD affected areas and 30 in the unaffected areas). The comparison of PMTCT indicators between the period before Ebola (2013) and during Ebola (2014) was done using the t- test for the means and the Chi-square test for the proportions. RESULTS: This study showed a substantial and significant reduction in the mean number of antenatal care visits (ANC) in the affected localities, 1617 ± 53 in 2013 versus 1065 ± 29 in 2014, p = 0.0004. This would represent 41% drop in health facilities' performance. On the other hand, in the unaffected localities, the fall was not significant. The same observations were made about the number of HIV tests performed for pregnant women and the number of HIV positive pregnant women initiating ARVs. The study also noted an increase in the proportion of women tested HIV+ but who did not receive ARVs (12% in 2013 versus 44% in 2014) and HIV+ pregnant women who delivered at home (18% in 2014 versus 7% in 2013). CONCLUSION: This study showed that PMTCT services, which are one of the key services to improve maternal and child health, were affected in Guinea during this Ebola outbreak in 2014 compared to 2013.

RESUMO

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.

RESUMO

OBJECTIVE: To report on the results of three size estimations of the populations of female sex workers (FSW) in five cities in Côte d'Ivoire and on operational lessons learned, which may be relevant for key population programmes in other parts of the world. METHODS: We applied three methods: mapping and census, capture-recapture and service multiplier. All were applied between 2008 and 2009 in Abidjan, San Pedro, Bouaké, Yamoussoukro and Abengourou. RESULTS: Abidjan was the city with the highest number of FSW by far, with estimations between 7880 (census) and 13 714 (service multiplier). The estimations in San Pedro, Bouaké and Yamoussoukro were very similar, with figures ranging from 1160 (Yamoussoukro, census) to 1916 (San Pedro, capture-recapture). Important operational lessons were learned, including strategies for mapping, the importance of involving peer sex workers for implementing the capture-recapture and the identification of the right question for the multiplier method. CONCLUSIONS: Successful application of three methods to estimate the population size of FSW in five cities in Côte d'Ivoire enabled us to make recommendations for size estimations of key population in low-income countries.

RESUMO

OBJECTIVE: Community ART groups (CAG), peer support groups involved in community ART distribution and mutual psychosocial support, were piloted to respond to staggering antiretroviral treatment (ART) attrition in Mozambique. To understand the impact of CAG on long-term retention, we estimated mortality and lost-to-follow-up (LTFU) rates and assessed predictors for attrition. METHODS: Retrospective cohort study. Kaplan-Meier techniques were used to estimate mortality and LTFU in CAG. Individual- and CAG-level predictors of attrition were assessed using a multivariable Cox proportional hazards model, adjusted for site-level clustering. RESULTS: Mortality and LTFU rates among 5729 CAG members were, respectively, 2.1 and 0.1 per 100 person-years. Retention was 97.7% at 12 months, 96.0% at 24 months, 93.4% at 36 months and 91.8% at 48 months. At individual level, attrition in CAG was significantly associated with immunosuppression when joining a CAG, and being male. At CAG level, attrition was associated with lack of rotational representation at the clinic, lack of a regular CD4 count among fellow members and linkage to a rural or district clinic compared with linkage to a peri-urban clinic. CONCLUSIONS: Long-term retention in this community-based ART model compares favourably with published data on stable ART patients. Nevertheless, to reduce attrition, further efforts need to be made to enroll patients earlier on ART, promote health-seeking behaviour, especially for men, promote a strong peer dynamic to assure rotational representation at the clinic and regular CD4 follow-up and reinforce referral of sick patients.

INTRODUCTION: Adolescents and young adults (AYA) face multiple barriers to accessing healthcare services, which can interact, creating complex needs that often impact health behaviours, leading to increased vulnerability to HIV. We aimed to identify distinct AYA subgroups based on patterns of barriers to HIV testing services and assess the association between these barrier patterns and sexual behaviour, socio-demographics, and HIV status. METHODS: Data were from Nigeria's AIDS Indicator and Impact Survey (NAIIS, 2018) and included 18,612 sexually active AYA aged 15-24 years who had never been tested for HIV and reported barriers to accessing HIV testing services. A Latent class analysis (LCA) model was built from 12 self-reported barrier types to identify distinct subgroups of AYA based on barrier patterns. Latent class regressions (LCR) were conducted to compare the socio-demographics, sexual behaviour, and HIV status across identified AYA subgroups. Sex behaviour characteristics include intergenerational sex, transactional sex, multiple sex partners, condom use, and knowledge of partner's HIV status. RESULTS: Our LCA model identified four distinct AYA subgroups termed 'low-risk perception' (n = 7,361; 39.5%), 'consent and proximity' (n = 5,163; 27.74%), 'testing site' (n = 4,996; 26.84%), and 'cost and logistics' (n = 1,092; 5.87%). Compared to adolescents and young adults (AYA) in the low-risk perception class, those in the consent and proximity class were more likely to report engaging in intergenerational sex (aOR 1.17, 95% CI 1.02-1.35), transactional sex (aOR 1.50, 95% CI 1.23-1.84), and have multiple sex partners (aOR 1.75, 95% CI 1.39-2.20), while being less likely to report condom use (aOR 0.79, 95% CI 0.63-0.99). AYA in the testing site class were more likely to report intergenerational sex (aOR 1.21, 95% CI 1.04-1.39) and transactional sex (aOR 1.53, 95% CI 1.26-1.85). AYA in the cost and logistics class were more likely to engage in transactional sex (aOR 2.12, 95% CI 1.58-2.84) and less likely to report condom use (aOR 0.58, 95% CI 0.34-0.98). There was no significant relationship between barrier subgroup membership and HIV status. However, being female, aged 15-24 years, married or cohabiting, residing in the Southsouth zone, and of Christian religion increased the likelihood of being HIV infected. CONCLUSIONS: Patterns of barriers to HIV testing are linked with differences in sexual behaviour and sociodemographic profiles among AYA, with the latter driving differences in HIV status. Findings can improve combination healthcare packages aimed at simultaneously addressing multiple barriers and determinants of vulnerability to HIV among AYA.

RESUMO

BACKGROUND: Violence against women and girls (VAWG) is a significant global public health problem and a violation of human rights experienced by one in three women worldwide. This study explores community perceptions of and responses to VAWG and challenges in accessing support services among female violence survivors in Arbaminch City. METHODS: We adopted a phenomenological explorative qualitative study design. A total of 62 participants including female violence survivors, religious leaders, service providers, police, women, and men in participated in interviews, focus group discussions, and observations in August 2022. Participants were selected purposively, and the findings were analyzed thematically. We applied data source and respondent triangulation to increase the findings' trustworthiness. RESULTS: Community perceptions of VAWG, specifically of intimate partner violence (IPV) and non-partner sexual violence (NPSV), varied depending on gender, age, and social position. IPV and NPSV were normalized through tolerance and denial by young and married men, while resistance to all forms of violence was common among women. Survivors of violence responded to the act of violence by leaving their homes, separating from their husbands, or taking harsh actions against their husbands, such as murder. Support for VAWG survivors was available through health care, free legal services, and a temporary shelter. Yet factors ranging from individual to societal levels, such as fear, lack of knowledge, lack of family and community support, and social and legal injustice, were barriers to accessing existing services. Nonetheless, violence survivors desired to speak about their experiences and seek psychosocial support. CONCLUSIONS: Our qualitative evidence gathered here can inform tailored VAWG prevention and response services such as interventions to shift social norms and the perception towards VAWG among different population group through raising awareness in schools, health care settings, faith-based venues, and using social media.
