Only one study to date has focused on people living with HIV (PLWH) who refused to participate in a HIV cure/remission-related clinical trial (HCCT)-"decliners" hereafter-that included analytical treatment interruption (ATI). Exploring why these persons refuse may provide valuable information to ensure more ethical recruitment and support in HCCTs within the bigger picture of improving HIV cure research. The qualitative component of the AMEP-EHVA-T02/ANRS-95052 study, called AMEP-Decliners, documented the experiences of French PLWH who refused to participate in EHVA-T02/ANRS-VRI07, a phase II randomized, placebo-controlled HCCT with ATI. AMEP-Decliners comprised semi-structured individual interviews with six decliners in two HIV care sites in France between September 2022 and March 2023. The interviews documented their expectations regarding HCCTs, reasons for refusal, and perceived factors that might have led them to participate. Audio files were transcribed, and an inductive thematic analysis was performed. Surprisingly, the main reason for refusal was not ATI but the trial monitoring. Besides the frequency of appointments, respondents emphasized the incompatibility with their active life. One underlying reason for refusal was that participating would have meant "break[ing] the carefree attitude about the disease," reflecting the substantial psychological burden associated with participation. Finally, respondents perceived that the trial's clinical team did not sufficiently recognize their "normal life" and the level of commitment required to participate, leading them to call for greater involvement by the team: "they have to make an effort too." Results from decliners' discourses highlighted that two levels of commitment to participation must be considered when developing HCCTs: psychological burden and logistical constraints. We suggest allowing home examinations and flexible appointment times, prioritizing face-to-face invitations in order to address the psychological burden associated with HCCT participation, and explaining the reasons for monitoring constraints when they cannot be alleviated. Further studies are necessary to confirm our results.

Chemsex is mostly approached through the prism of risk-taking, neglecting the pleasure and social linking dimensions. However, feedback from the field and few studies highlights a diversity of chemsex practices and relationships to chemsex (RtC). Using Q-methodology, we identified the main RtC and their divergences and convergences, to help develop tailored prevention and care programs. Q-methodology enables the exploration of complex subjective structures and provides a multifaceted picture of a phenomenon. In 2019-2020, we asked 126 men who have sex with men living in France and practicing chemsex to rank order 37 statements. RtC were defined through by-person factor analysis and interpreted using a holistic process. Five RtC emerged, highlighting various motivations for practicing chemsex, relationships to substance use and to sexuality, and regulation strategies implemented: (1) From compensation to fulfillment; (2) The pleasure-seeking manager; (3) Between addiction and management; (4) From curiosity to the destruction of sexuality; and (5) From the hope of compensation to disillusion. Respondents all agreed on two statements: the need to first accept oneself as a drug user in order to be able to manage drug use, and the possibility of harm reduction during chemsex sessions. Our results are the first to elicit the main RtC and the intricacies between the dimensions at stake. The five analysis-based narratives derived from RtC might facilitate discussion during interviews or support groups on chemsex, and could serve as a standardized survey tool. Our findings advocate longitudinal studies to identify factors associated with shifting from one RtC to another., (© 2024.

Background: Understanding the reasons for and consequences of bodyweight change in people living with HIV initiating antiretroviral therapy (ART) is crucial to optimising long-term health and wellbeing. We aimed to examine bodyweight trends and associated factors among individuals with well estimated dates of HIV-1 seroconversion., Methods: In this cohort study, we pooled retrospective data from clinical records of participants in CASCADE aged 16 years and older recruited from clinics in France, Greece, the Netherlands, Spain, Sweden, the UK, and Canada. All participants had well estimated dates of HIV-1 seroconversion, seroconverted between Jan 1, 2007, and Dec 31, 2022 (HIV-1 positive antibody test within 12 months of an HIV-1 negative antibody test, or other laboratory evidence of seroconversion), initiated ART within 1 year of seroconversion, and were previously ART-naive. Participants were followed up to the time of data pooling (May 31, 2023). We modelled bodyweight changes after ART initiation by ART class, BMI categories, and other demographic characteristics using linear mixed models., Findings: Of 15 755 potentially eligible participants, 5698 met inclusion criteria. Of those, 5148 (90·3%) were assigned male at birth, 517 (9·1%) were assigned female at birth, and 33 (0·6%) had sex not known. 2778 (48·8%) participants initiated integrase strand transfer inhibitor (INSTI)-based ART regimens, 1809 (31·7%) initiated protease inhibitor-based regimens, and 1111 (19·5%) initiated non-nucleoside reverse transcriptase inhibitor (NNRTI)-based regimens. The majority of participants were men who have sex with men (MSM; 4519 [79·3%]). Median age at seroconversion was 33·7 years (IQR 26·9-43·2). Bodyweight changes differed significantly by ART class within all baseline BMI categories (BMI <18·5 kg/m 2 p=0·026, BMI 18·5-24·9 kg/m 2 p<0·0001, BMI 25·0-29·9 kg/m 2 p=0·0021, and BMI ≥30·0 kg/m 2 p=0·0033; ART class and BMI interaction p=0·011). Participants with BMI less than 30 kg/m 2 on regimens including both INSTI and tenofovir alafenamide gained 4·76 kg (95% CI 4·05-5·46) or more at 3 years. Of those with baseline BMI 18·5-24·9 kg/m 2 , 31·3% (95% CI 29·5-33·1) on INSTI-based regimens, 25·3% (23·0-27·7) on protease inhibitor-based regimens, 20·4% (18·8-22·9) on NNRTI-based regimens, 37·4% (33·9-40·9) on tenofovir alafenamide-based regimens, and 38·4% (34·6-42·1) on tenofovir alafenamide and INSTI-based regimens had gained more than 10% of their baseline bodyweight at 3 years. The greatest 3-year bodyweight gains by individuals on INSTI-based regimens and with BMI 18·5-24·9 kg/m 2 were in women (5·63 kg [95% CI 4·92-6·35]), and people originating from sub-Saharan African (5·76 kg [5·06-6·46]), compared with MSM (3·82 kg [3·50-4·13])., Interpretation: Our findings suggest a direct effect of INSTIs and tenofovir alafenamide on bodyweight gain, rather than a return to health effect. Given the known risk for cardiometabolic disease, bodyweight management needs to be part of the overall care of individuals prescribed these drugs., Funding: ViiV Healthcare UK, Janssen Pharmaceutica, and Merck Sharp & Dohme., Competing Interests: Declaration of interests DC reports personal fees from Pfizer (2022) for a lecture outside the submitted work.

People living with HIV (PLHIV) are at greater risk of illness and death from vaccine-preventable diseases. This study aimed to identify the predictors associated with the recommended vaccination schedule for this group. This was a single-center cross-sectional study conducted in a large Brazilian municipality, evaluating the vaccination statuses of 645 PLHIV for nine immunizers. The primary outcome was the adequacy of the vaccination schedule. The vaccination status was assessed for the diphtheria/tetanus, hepatitis B, hepatitis A, measles/mumps/rubella, yellow fever, 13- and 23-valent pneumococcal, meningococcal C, and HPV vaccines. Those who had received all of the recommended vaccinations in accordance with the schedule established by the government at the time of the assessment, without any delays, were classified as having received an "adequate schedule". The independent variables included sociodemographic, clinical-epidemiological, and social vulnerability factors, analyzed by multiple logistic regression with adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs). Only 47 individuals (7.3%) had an adequate vaccination schedule for all vaccines. The vaccines with the highest adequacy rate were diphtheria and tetanus (533; 82.6%), and the one with the lowest rate was measles/mumps/rubella (MMR) (243; 37.7%). The main predictors of a complete vaccination schedule were the age group, place of clinical follow-up, and where they received their last doses of vaccines. Educational interventions for PLHIV and health professionals are needed to improve the vaccination coverage in this group.

This is a quasi-experimental study that assessed PLHIV vaccination coverage before and after health professionals participated in a training course on PLHIV immunization. The vaccination coverage of 645 PLHIV was assessed in the pre-intervention phase. The vaccine with the best coverage was diphtheria and tetanus (82.64%) and the one with the lowest rate of adequately vaccinated was measles, mumps, and rubella (38.27%). Individuals aged between 30 and 39 years had a 74.00% (1-0.26) lower chance of having the full vaccination schedule when compared to those aged between 10 and 19 years, and among those over 40 years, the chance was 87.00% (1-0.13) lower. Those who were vaccinated in Specialized Care Services (SCS) were 5.77 times more likely to be adequately vaccinated when compared to those who were vaccinated in other health services. Regarding the entire vaccination schedule evaluated, the number of adequately vaccinated increased from 47 (7.29%) to 76 (11.78%). Interventions targeting health professionals were effective in increasing vaccination coverage among PLHIV; however, the achieved coverage remained below the desired level. It is necessary to act on health professionals' knowledge and other aspects to effectively increase vaccination coverage.

Vaccination coverage against hepatitis A virus (HAV), hepatitis B virus (HBV), and human papillomaviruses (HPV) is insufficient among men who have sex with men (MSM), partly because of their high prevalence of vaccine hesitancy (VH) specific to these vaccines. This study aimed to investigate determinants of specific VH in MSM, focusing on characteristics of their sexual activity, propensity to use prevention tools and medical care, disclosure of sexual orientation to health care professionals (HCPs), and perceived stigmatization. A cross-sectional electronic survey (February - August 2022) collected perceptions of HBV, HAV, and HPV, and of their respective vaccines among 3,730 French MSM and enabled the construction of a specific VH variable. Using agglomerative hierarchical cluster analysis, we constructed a typology of MSM sexual and prevention practices. We identified three MSM clusters (low- (C1, 24%), moderate- (C2, 41%), and high- (C3, 35%) "sexual activity/medical engagement") that showed an increasing gradient in the use of medical prevention with regular medical care and exposure to high-risk sexual practices. A multiple ordinal logistic regression showed that overall specific VH was higher in the C1 cluster and in men who had not informed their physician of their sexual orientation. This typology could usefully help to adapt vaccination communication strategies for MSM prevention program according to patients' profiles. HCPs should be encouraged and trained to ask men about their sexual practices and to provide appropriate vaccination recommendations nonjudgmentally.

The HIV epidemics in Cambodia is concentrated in key populations (KPs). Pre-exposure prophylaxis (PrEP) has been officially approved in the country since 2019. However, its use may still be controversial after a PrEP clinical trial was interrupted in Cambodia after being deemed unethical in 2004. In this context, it was necessary to evaluate PrEP acceptability and administration preferences of KPs in Cambodia, with a view to increasing roll-out and uptake. We conducted a qualitative study in 2022 comprising six focus groups and four semi-structured individual interviews with transgender women, men who have sex with men, male entertainment workers, venue-based female entertainment workers (FEW), street-based FEW, and PrEP users who participated in a PrEP pilot study that started in 2019. Overall, KPs positively perceived PrEP, with some reservations. They preferred daily, community-based PrEP to event-driven, hospital-based PrEP, and highlighted that injectable PrEP would be a potential option if it became available in Cambodia. We recommend (i) proposing different PrEP regimens and PrEP delivery-models to broaden PrEP acceptability and adherence in Cambodia (ii) increasing the number of community-based organisations and improving the services they offer, (iii) rolling out injectable PrEP when it becomes officially available, and (iv) improving PrEP side effects information.

Objectives: Although oral pre-exposure prophylaxis (PrEP) for HIV is being rolled out in West Africa, data on sexually transmitted infections (STIs) in PrEP users are scarce. We assessed the prevalence, incidence and determinants of bacterial STIs in men who have sex with men (MSM) taking PrEP in Burkina Faso, Côte d'Ivoire, Mali and Togo., Methods: A prospective cohort study among MSM initiating PrEP as part of a comprehensive HIV prevention package was conducted between 2017 and 2021 in community-based clinics in the four study countries. Molecular screening for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) was performed at months 0, 6 and 12. Serological testing for syphilis was performed every 3 months over the first year of follow-up. Determinants of CT and/or NG incidence were identified using Poisson generalised linear mixed models., Results: A total of 598 participants with a median age of 24.7 years were included. Prevalence of CT and/or NG was 24.4% (95% CI 21.0 to 28.1), 22.4% (95% CI 18.4 to 26.8) and 29.0% (95% CI 24.2 to 34.1) at months 0, 6 and 12, respectively. The prevalence of syphilis ranged from 0.2% (95% CI 0.0 to 0.9) at month 0 to 0.8% (95% CI 0.2 to 2.4) at month 12. Ninety incident CT and/or NG infections occurred during a total follow-up time of 280.6 person-years (incidence rate 32.1 per 100 person-years, 95% CI 25.8 to 39.4). Three incident syphilis infections were detected during a total follow-up time of 459.7 person-years (incidence rate 0.7 per 100 person-years, 95% CI 0.1 to 1.9). CT and/or NG incidence was associated with condomless insertive anal sex (adjusted incidence rate ratio 1.96, 95% CI 1.04 to 3.71, p=0.038)., Conclusions: CT and NG were frequent but syphilis was very infrequent in MSM using HIV PrEP in West Africa. HIV programme managers should integrate STI services into PrEP programmes., Competing Interests: Competing interests: CL has received a travel grant and fees for a meeting from Gilead Sciences.

Introduction: Given the high infection rate of sexually transmitted infections (STI) among migrant women sex workers (WSWs), it is necessary to understand how to improve prevention, information and care for this vulnerable population. Community health workers (CHWs), by linking community to health services, are positioned to improve health outcomes in migrant communities. This article aims to describe a pilot innovative intervention performed by CHWs to improve sexual health in migrant WSWs., Methods: This one-year intervention study used a respondent-driven sampling (RDS) to recruit a representative cohort of migrant WSWs in Marseille, France. Four CHWs were recruited from different communities and participated in all stages of the research. They performed individual and group interventions of prevention, support in care and empowerment. Data on participant characteristics, type of intervention and adherence to the intervention were reported via questionnaires given to participants. Simultaneously, semi-structured interviews and informal interviews of migrant WSW, CHWs and care providers were carried out., Results: A total of 132 migrant WSWs were included in the cohort. Very few of them knew about PrEP (12%) or already used HIV post-exposure treatment (9%). Migrant WSWs were often victims of rape or racism, 15 and 21%, respectively. In two-thirds of cases the level of health literacy was low. Participants suffered from a combination of vulnerability factors: difficulties with access to social rights, food or housing. Only 13% reported having benefited from medical follow-up or assistance by an NGO in the 3 months prior to the program. By 3 months, more than one third of the participants had been tested for HIV (35%) and 63% knew about PrEP. A total retention rate of 70% was reported in the cohort after 6 months., Conclusion: CHWs enabled to improve care access for migrant WSWs by improving the collaboration between care and social actors at a local level. Through these "bring-back-to" interventions for this hard-to-reach population, CHWs enabled an optimization of the care pathway. Our results also highlight the importance of a population-based approach for individual and group support of empowerment interventions in order to strengthen their capacity for action., 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 © 2024 Mosnier, Hoyer, Artigas, Regnault, Richard, Michels, Mosnier, Inegbeze, Robledo, Spire, Vandentorren, Lescaudron, Eldin and Roux.)

Introduction: In a context of declining condom use and high sexually transmitted infection (STI) incidence, the diffusion of "treatment as prevention" (Tasp) and more recently pre-exposure prophylaxis (PrEP) may have changed the sexual behaviour of newly diagnosed men who have sex with men (MSM) with HIV., Methods: Six hundred and nine MSM were enrolled and followed annually between 2014 and 2021 in the ANRS PRIMO Cohort (ClinicalTrials.gov:NCT03148964) from the time of HIV seroconversion. We studied changes over calendar time in sexual behaviour before and after HIV diagnosis. Factors associated with inconsistent condom use (ICU) after HIV diagnosis, PrEP use by partner(s) and bacterial STI acquisition were studied in random-effects models., Results: In the 6 months preceding HIV diagnosis, the number of sexual partners decreased from a median of 10 (IQR: 4-19) in 2014 to 6 (3-11) in 2021. After HIV diagnosis, ICU increased from 57.1% (16/28) of visits in 2014 up to 84.2% (229/272) in 2020-2021. Up to 25% (63/229) of MSM with HIV in recent years reported the use of PrEP by their partner(s) as the reason for ICU; these MSM were less frequently in a stable relationship, had a higher number of sexual partners and higher education level than those who did not report the use of PrEP by their partner(s). STI incidence after HIV diagnosis increased between 2014 and 2016 and remained high afterwards. STI risk was no longer associated with PrEP use by partners after adjustment for the number of partners and calendar period. ICU, age below 35 years, not being in a stable relationship, higher number of sexual partners were independently associated with an increased risk of STI., Conclusions: Implementation of TasP and more recently PrEP has led to major changes in the sexual behaviour of MSM with HIV. ICU has become overwhelmingly prevalent, PrEP use by the partner increasingly being the reported reason for ICU, behind TasP, which remains the main reason. Characteristics of MSM at the time of diagnosis of HIV have changed, with fewer number of sexual partners today than in 2014, which must lead to broaden the indications for PrEP prescription. STIs incidence remains high in MSM with HIV and requires improvements in screening and prevention methods such as pre- or post-exposition antibiotics or vaccines., (© 2024 The Authors.

Background: The presence of untreated sexually transmitted infections (STIs) significantly increases the chance of acquiring HIV. In Brazil, testing for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) among Pre-Exposure Prophylaxis (PrEP) users is insufficient, and syndromic treatment is a priority in clinical practice. Multi-site testing for CT/NG improves thescreening of asymptomatic cases and ensures timely treatment. Therefore, it is essential for HIV prevention. This study aims to test the importance of two-site testing for better screening of these pathogens and to determine whether the presence of symptoms is an indicator of CT/NG infection., Methods: This is a cross-sectional study carried out in four public infectious diseases clinics in São Paulo State, Brazil between January of 2022 and March of 2023. All participants had an anal swab and a first-pass or mid-stream urine collected for CT/NG analysis by Polymerase chain reaction (PCR). Data about sociodemographic, sexual behavioural and clinical aspects were collected. Pathway analysis was used to examine the direct and indirect relationships between variables according to the theoretical model., Results: We screened 171 PrEP users which had two samples collected, resulting in 342 samples. Comparing the anatomic sites, the urine samples showed lower sensitivity for CT and NG than anal samples. Gonorrhoea was directly linked to lower age (β= -0.161, p = 0.001). Time of PrEP use was directly associated with CT infection (β = 0.202; p = 0.042) and inversely associated with dysuria (β= -0.121, p = 0.009). Lower occurrence of yellow-green secretion was linked to detection of CT (β= -0.089, p = 0.005) and NG (β= -0.048, p = 0.002) infections. Foul-smelling discharge was directly associated with CT (β = 0.275, p = 0.004) and NG (β = 0.295, p = 0.037) infection., Conclusion: The symptoms are a bad indicator of CT and NG infection, and the screening must be done in more than one site since most of the positive results would be missed if only urines were tested. In the case of testing only one anatomical site, specifically the urethra, the CT/NG incidence and prevalence would be underestimated. The two-sites testing improves detection rates of CT/NG, and PrEP follow-up benefits people offering STI testing., (© 2024. The Author(s).)

HIV is highly prevalent in men who have sex with men (MSM) in West Africa. Many MSM in the region also have sex with women (MSMW). Accordingly, they are a potential bridge subpopulation for HIV transmission to women. We aimed to evaluate the proportions and characteristics of West African MSMW at high behavioral risk of acquiring HIV from male partners and transmitting it to female partners (HBRMF). The cohort ANRS-12324 CohMSM Study included 630 HIV-negative MSM in Burkina Faso, Cote d'Ivoire, Mali, and Togo. Among MSMW (i.e., with ≥ 1 female partner) in the cohort, HBRMF was identified using trajectory models based on seven at-risk sexual practices with male and female partners, including inconsistent condom use, multiple partnerships, and receptive same-sex anal intercourse. To assess the relevance of using trajectory models, we compared the proportions of participants who seroconverted during the cohort follow-up among those at HBRMF and those not at HBRMF. Factors associated with HBRMF were identified using a generalized estimation equation logistic regression model accounting for longitudinal data. Approximately half (47%) of the 304 MSMW (22% of all CohMSM study participants) were at HBRMF. This group accounted for 75% of the 28 HIV seroconversions observed during follow-up (p = 0.001). HBRMF was positively associated with being aged < 25 years (aOR 95% CI 1.67 [1.23-2.27]), being sexually attracted only to men (1.97 [1.38-2.78]), feelings of loneliness (1.92 [1.38-2.65]), and homonegative violence score (1.22 [1.05-1.41]). HBRMF was negatively associated with having had both stable and casual female partners in the previous 6 months (0.34 [0.20-0.60] vs. only a stable female partner). HBRMF tended to be negatively associated with having ≥ 4 sexual intercourses with female partners in the previous four weeks (0.54 [0.27-1.06] vs. no intercourse). Establishing official relationships with women might be a strategy for young and/or stigmatized MSMW to comply with social pressure to display a heterosexual lifestyle. However, this seems to increase the risk of HIV transmission to female partners. In the present study, almost half of MSMW were at HBRMF. This result stresses the need to adapt HIV research and prevention to MSMW and their female partners., (© 2023. The Author(s).)

Community-based research, that is, the meaningful involvement of affected populations in the production of scientific knowledge that concerns them, is a political struggle and an ethical necessity. Coalition PLUS, an international network of organizations (most of them NGOs) fighting against HIV and hepatitis, created a community-based research laboratory (CBRL) composed of people from more than sixteen countries and various disciplinary fields. The objectives of the CBLR are to build research capacity, ensure collaboration with local and international academic research centers, and develop international research projects. The CBRL acts as a bridge between different partners, reconciling sometimes divergent interests, and must provide mediation and support to promote dialogue, transparency, and a relationship of trust between the communities and academic researchers. However, the need for scientific legitimacy obliges us to continuously seek a balance between responding to the needs of the field and using rigorous scientific methods, while optimizing and prioritizing existing resources. The permanent quest for this balance has led the CBRL to reorganize its mode of operation to optimize existing synergies with academic research laboratories, with a view to asserting its scientific legitimacy and continuing to contribute to social transformation through community-based research that is both innovative and of high quality. This paper provides a critical reflection on the issues, challenges, practices, and solutions of community-based research within the Coalition PLUS network.

The Groupe de r&#233;flexion avec les associations de malades (GRAM)&#8212;a joint scientist/association think tank at the French National Institute of Health and Medical Research (INSERM)&#8212;has reflected, on the basis of internal surveys and the experiences of its members, on focus points concerning good practice to help partners involved in participatory research projects. In this article, we list these focus points and highlight the need to afford partners opportunities for dialogue, in order to give good chances of success to participatory research projects, in both the interest of associations and researchers.

In developed countries, vaccinations against hepatitis B (HBV), hepatitis A (HAV), and human papillomavirus (HPV) are often recommended to men who have sex with men (MSM) because of the risky sexual practices in which some engage. Vaccine coverage against these diseases is not optimal in France, probably due in part to vaccine hesitancy (VH). The overall aim of this survey among MSM was to estimate the prevalence of different grades of VH for these vaccines as well as of general VH (toward any vaccine). The specific objectives were to study the sociodemographic correlates of MSM specific and general VH and its association with vaccine uptake. A cross-sectional electronic survey (February-August 2022) collected information from 3,730 French MSM about their perceptions of HBV, HAV, and HPV and their related vaccines, to construct "specific VH" variables. Information about their past vaccination behaviors for any vaccine was used to construct a "general VH" variable, based on the World Health Organization definition. Almost 90% of MSM showed moderate or high specific VH for HBV, HAV, and/or HPV, and 54% general VH. A higher education level and comfortable financial situation were associated with lower grades of specific and general VH. Younger age was associated with less frequent specific VH and more frequent general VH. Specific VH, versus general, was more strongly associated with frequent self-reported non-vaccination against these three disease. Addressing their concerns about vaccines, improving their knowledge of vaccine-preventable sexually transmitted infections, and motivating them to get vaccinated are public health priorities.

Background: Information concerning the impact of the COVID-19 health crisis on populations most affected by HIV and hepatitis C virus (HCV; or key populations [KP]), and those working with these populations in community settings, is limited. Community-based organizations working in the field of HIV and viral hepatitis are well placed to identify and meet the new needs of KP owing to the health crisis., Objective: This study aims to describe the development and implementation of an exploratory and descriptive multicountry, community-based research program, EPIC (Enquêtes Pour évaluer l'Impact de la crise sanitaire covid en milieu Communautaire), within an international network of community-based organizations involved in the response to HIV and viral hepatitis. The EPIC program aimed to study the impact of the COVID-19 health crisis on KP or people living with HIV or HCV and people working with these populations at the community level (community health workers [CHWs]) and to identify the key innovations and adaptations in HIV and HCV services., Methods: A general protocol and study documents were developed and shared within the Coalition PLUS network. The protocol had a built-in flexibility that allowed participating organizations to adapt the study to local needs in terms of the target population and specific themes of interest. Data were collected using surveys or interviews., Results: From July 2020 to May 2022, a total of 79 organizations participated in the EPIC program. Across 32 countries, 118 studies were conducted: 66 quantitative (n=12,060 among KP or people living with HIV or people living with HCV and n=811 among CHWs) and 52 qualitative (n=766 among KP or people living with HIV or people living with HCV and n=136 among CHWs)., Conclusions: The results of the EPIC program will provide data to describe the impact of the health crisis on KP and CHWs and identify their emerging needs. Documentation of innovative solutions that were put into place in this context may help improve the provision of services after COVID-19 and for future health crises., International Registered Report Identifier (irrid): DERR1-10.2196/45204., (©Rosemary M Delabre, Marion Di Ciaccio, Nicolas Lorente, Virginie Villes, Juliana Castro Avila, Adam Yattassaye, César Bonifaz, Amal Ben Moussa, Ingrid-Zaïre Sikitu, Niloufer Khodabocus, Rosa Freitas, Bruno Spire, Maria Amélia Veras, Luis Sagaon-Teyssier, Gabriel Girard, Perrine Roux, Annie Velter, Valérie Delpech, Jade Ghosn, Lucas Riegel, Daniela Rojas Castro.

Most domestic servants (DS) in Mali are very young female migrants living in precarious conditions. We aimed to understand their living and working conditions in relation to their general and sexual health. Seven focus groups (53 participants) were conducted by the DS community-based organization ADDAD. Narratives were thematically analyzed using an inductive method. The dominant emerging theme was DS' strong dependence on their employers. Employers' attitudes regarding DS workload, the provision of food, water and hygiene products, housing conditions, and healthcare cover, appeared decisive for DS' physical and mental health, and the type of healthcare they used (self-medication, traditional care, healthcare facilities). Psychological, physical and sexual violence in employers' households was frequent. HIV/STI prevention knowledge was poor. These results highlight the serious risks for DS in terms of HIV/STI and unwanted pregnancies. DS were interested in receiving healthcare from ADDAD; this was motivated by the organization's trusting and understanding community-based environment, and DS' fear of discrimination in healthcare facilities. This study highlights the relevance of tackling the defense of rights and sexual health promotion for DS at the community level. Its findings can help identify research questions to evaluate the extent to which DS constitute a key HIV population.

Objectives: Recently acquired HIV is a critical time when people may experience debilitating symptoms and is when they are most likely to pass HIV on. Qualitative research offers insights into lived experiences and a deeper understanding of the contextual factors underlying HIV acquisition. We aimed to synthesize qualitative literature on recently acquired HIV., Design: Systematic review and textual narrative synthesis., Methods: We searched MEDLINE, CINAHL Plus, PsycINFO and Sociology Database. Articles were screened, and two authors completed full text review and data extraction. Quality appraisal was conducted (Critical Appraisal Skills Programme Qualitative Studies Checklist) and certainty of findings graded (GRADE-CERQual)., Results: We reviewed 1890 articles (1554 following de-duplication), excluding 1539. Fifteen articles were included and an additional article was included after updating the search. We identified 15 themes, three of which we have high confidence in: recent acquisition of HIV facilitates understanding of circumstances of HIV acquisition; indeterminate HIV tests generate uncertainty and anxiety; and people with recently acquired HIV are motivated to reduce risk of onward transmission., Conclusions: Our findings highlight the importance of continued research into recently acquired HIV, as well as the need for support to manage the emotional impact of indeterminate test results and negotiate risk reduction. We found no studies exploring sexual risk in the context of recently acquired HIV, or use of pre-exposure prophylaxis or treatment as prevention. The literature is primarily focused on HIV acquisition from an individual and behavioural perspective, neglecting important aspects of lived experience such as immediate ART, stigma, and health and wellbeing., (Copyright © 2023 The Author(s).

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.

Background: Partner notification interventions are complex and assessing their effectiveness is challenging. By reviewing the literature on the effectiveness of partner notification interventions, our aim was to evaluate the choice, collection, and interpretation of outcomes and their impact on study findings., Methods: We conducted a systematic review of individual-level randomised controlled trials evaluating the effectiveness of partner notification interventions for bacterial STIs, HIV or sexually transmitted HCV in high-income countries since 2000. Partner notification interventions included assisted patient referral interventions and expedited treatment. The content analysis was carried out through a narrative review., Results: In the 9 studies that met the inclusion criteria, 16 different outcomes were found. In most studies, one or two outcomes assessing partner notification practices were associated with an outcome reflecting STI circulation through index case reinfections. These outcomes assessed the main expected effects of partner notification interventions. However, partner notification is composed of a succession of actions between the intervention on the index case and the testing and/or treatment of the notified partners. Intermediate outcomes were missing so as to better understand levers and barriers throughout the process. Potential changes in participants' sexual behaviour after partner notification, e.g. condom use, were outcomes reported in only two studies assessing interventions including counselling. Most outcomes were collected through interviews, some weeks after the intervention, which might lead to desirability and attrition biases, respectively. Assessment of the effectiveness of partner notification interventions on partner testing/treatment was limited by the collection of data from index cases. Few data describing index cases and their partners were provided in the studies. Additional data on the number and type of exposed partners and the proportion of partners already aware of their infection before being notified would help to interpret the results., Conclusions: These insights would help to understand why and under what conditions the intervention is considered effective and therefore can be replicated or adapted to other populations and contexts., (© 2023.

Background: Data on human immunodeficiency virus (HIV) seroconversion among men who have sex with men (MSM) using pre-exposure prophylaxis (PrEP) in West Africa are needed. This study aimed to document HIV seroconversion and associated determinants, PrEP adherence, plasma drug concentrations, and HIV drug resistance in MSM using event-driven or daily PrEP in Burkina Faso, Côte d'Ivoire, Mali, and Togo., Methods: A prospective cohort study was conducted in 2017-2021 among HIV-seronegative MSM aged 18 or over who were at high risk of HIV infection. Participants could choose between event-driven and daily PrEP, switch regimens, and discontinue or restart PrEP. The determinants of HIV incidence were investigated using a multivariate mixed-effects Poisson regression analysis., Results: A total of 647 participants were followed for a total time of 1229.3 person-years. Of 5371 visits, event-driven PrEP was chosen in 3873 (72.1%), and daily PrEP in 1400 (26.1%). HIV incidence was 2.4 per 100 person-years (95% confidence interval [CI] 1.5-3.6) for event-driven PrEP, and 0.6 per 100 person-years (95% CI .1-2.3) for daily PrEP (adjusted incidence rate ratio 4.40, 95% CI 1.00-19.36, P = .050). Adequate adherence was lower with event-driven than daily PrEP (44.3% vs 74.9%, P < .001). Plasma drug concentrations were undetectable in 92 (97.9%) of the 94 measures taken for 23 participants who seroconverted. Only 1 participant had resistance to PrEP drugs., Conclusions: HIV seroconversions mainly occurred in participants who chose event-driven PrEP. The study's data highlighted major difficulties with adherence to this regimen. Improving adherence to event-driven PrEP constitutes a major research and public health priority in this context., Competing Interests: Potential conflicts of interest. G.

Background: The World Health Organization recommends pre-exposure prophylaxis (PrEP) for all populations at substantial risk of HIV infection. However, at-risk women very rarely use PrEP in France-this represents a critical issue among migrant women sex workers (MWSWs). Previous studies on PrEP use among women sex workers or migrants focused on individual or social determinants of motivation. However, operational studies in real-word settings using a holistic population approach to maximize PrEP adherence among MWSWs are lacking., Objective: FASSETS (ie, "Favoriser l'Accès à la Santé Sexuelle des Travailleuses du Sexe"; English: "facilitate the access to Sexual Health in women sex workers") is a participative, multilevel, mixed methods study aiming to improve global knowledge of and access to sexual health care and PrEP among MWSWs through targeted empowerment strategies., Methods: This study comprises several phases: (1) phase 1: an initial qualitative study combining semistructured interviews, informal interviews, and participative observations will be performed among MWSWs, local community nongovernmental organizations, and institutions providing sexual reproductive health services to identify the determinants of PrEP access among MWSWs and for respondent-driven sampling (RDS); (2) phase 2: the size of the hidden MWSW population is estimated in Marseille through capture-recapture (the RDS survey will serve as "recapture"); (3) phase 3: a longitudinal cohort will be formed through RDS to represent the MWSW population with a goal of 150 inclusions-this cohort will be followed up for 12 months, and sequential questionnaires exploring medical history; knowledge of sexual health, HIV, and sexually transmitted infections; migration route; and current living conditions will be administered at inclusion (month 0) and months 3, 6, and 12 to measure the following interventional phase's outcomes; and (4) phase 4: an interventional study with community empowerment actions about sexual health and PrEP will be conducted with community health workers; standardized questionnaires and semistructured interviews, observations, and focus groups will highlight MWSWs' experiences with empowerment resources, concerns about sexual health, and especially PrEP use or uptake, and we will evaluate whether and how community-adapted empowerment actions conducted by community health workers are effective in increasing access to sexual health, prevention and screening of sexually transmitted infections, and PrEP knowledge and access among MWSWs., Results: Recruitment commenced on March 1, 2022. We estimate the follow-up period to end on September 30, 2023., Conclusions: This multiphase study will provide robust evidence about the magnitude of the MWSW population in Marseille (the second largest town in France) and their current conditions of living, access to and knowledge of sexual health, and PrEP access. Using a mixed methods analysis, we will investigate whether individual and collective community health empowerment approaches can facilitate access to PrEP and its initiation, use, and adherence in this vulnerable population., International Registered Report Identifier (irrid): DERR1-10.2196/42844., (©Emilie Mosnier, Fernanda Artigas, Elodie Richard, Maxime Hoyer, David Michels, Stephanie Vandentorren, Gabriel Girard, Nicolas Nagot, Hippolyte Regnault, Marine Mosnier, Grâce Inegbeze, Perrine Roux, Bruno Spire, Carole Eldin.

Gundo-So is a community-based programme developed by and for women living with HIV (WLHIV) in Mali through the ARCAD-Santé-PLUS association. It provides support, co-constructed with WLHIV, to develop strategies on whether or not to disclose their status. The aim of the ANRS-12373 research is to evaluate the impact of this programme in the short and medium term. As part of this research, semi-structured interviews were conducted with participants (14). These interviews were analysed thematically. Three themes are presented here: positive feedback from the programme, which enabled them to be listened to and supported them both psychologically and financially. The impact of the programme on the participants' social network is also described, in terms of the links made with peers met during the programme. Finally, a new perspective on issues such as disease management, which improved through the contribution of knowledge, and also through the development of psychosocial resources. The programme enabled participants to acquire psychosocial skills, the ability to effectively self-manage their condition, and strategies on whether or not to disclose their HIV status. Participants' empowerment and social support in relation to the disease were developed through the programme, particularly through the links created with other women living with HIV.

Introduction: Since the advent of HIV pre-exposure prophylaxis (PrEP), stigma has been shown to be a major barrier to its uptake and adherence. It is therefore essential to define the proportion of users who consider that PrEP can negatively impact their image and the factors associated with this perception., Method: We performed a multivariable logistic regression on data from the 2567 participants in the ANRS-PREVENIR study who answered the outcome question., Results: Almost one-third of the sample (comprising mostly cisgender men who have sex with men [94.3%]) considered that taking PrEP could give others a negative image of them. Younger participants (adjusted odds ratio [aOR] 0.98; 95% confidence interval [CI] 0.97-0.99) and more psychologically vulnerable participants (i.e., lower self-esteem score [aOR 0.98; 95% CI 0.96-0.99] and higher depression score [aOR 1.02; 95% CI 1.00-1.03]) were also more likely to have this perception. In contrast, participants encouraged to take PrEP by their main partner (aOR 0.67; 95% CI 0.51-0.88) and friends (aOR 0.79; 95% CI 0.66-0.95), and those who protected themselves more because they had knowledge of their most recent sexual partner's HIV status (aOR 0.83; 95% CI 0.69-0.99) and systematic use of PrEP and/or condoms during intercourse in the previous 3 months (aOR 0.80; 95% CI 0.67-0.96) were less likely to have this perception., Discussion: Given the strong interrelation between stigmatization (real or perceived), risky behaviours and adherence, our results emphasize the need for HIV prevention campaigns to promote a positive image of PrEP users. They also show that stigmatization and its effects need to be fully considered to improve HIV prevention offers to current and potential PrEP users who are most likely to be psychologically vulnerable., (© 2023 The Authors.

Introduction: Despite the availability of pre-exposure prophylaxis (PrEP) and antiretroviral therapy (ART), 21 793 people were newly diagnosed with HIV in Europe in 2019. The Concerted action on seroconversion to AIDS and death in Europe study aims to understand current drivers of the HIV epidemic; factors associated with access to, and uptake of prevention methods and ART initiation; and the experiences, needs and outcomes of people with recently acquired HIV., Methods and Analysis: This longitudinal observational study is recruiting participants aged ≥16 years with documented laboratory evidence of HIV seroconversion from clinics in Canada and six European countries. We will analyse data from medical records, self-administered questionnaires, semistructured interviews and participatory photography. We will assess temporal trends in transmitted drug resistance and viral subtype and examine outcomes following early ART initiation. We will investigate patient-reported outcomes, well-being, and experiences of, knowledge of, and attitudes to HIV preventions, including PrEP. We will analyse qualitative data thematically and triangulate quantitative and qualitative findings. As patient public involvement is central to this work, we have convened a community advisory board (CAB) comprising people living with HIV., Ethics and Dissemination: All respective research ethics committees have approval for data to contribute to international collaborations. Written informed consent is required to take part. A dissemination strategy will be developed in collaboration with CAB and the scientific committee. It will include peer-reviewed publications, conference presentations and accessible summaries of findings on the study's website, social media and via community organisations., Competing Interests: Competing interests: The funders did not participate in the study design and will not intervene in its process, analysis or publication of the findings.

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.

Background: Initiating same-day ART for newly HIV-diagnosed individuals reduces secondary HIV transmissions and the risk of them being lost to follow-up between diagnosis and initiation of ART., Methods: The FAST study was a national, prospective, single-arm study assessing the efficacy, safety and feasibility of bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) in a same-day initiation model. ART had to be started on the first medical appointment, before any laboratory results were available. Participants completed a self-administered questionnaire at each visit including a HIV anxiety 5-point Likert scale. The primary outcome was the proportion of participants in the ITT population with plasma HIV RNA (pVL) < 50 copies/mL at Week (W) 24 using the FDA Snapshot algorithm., Results: Overall, 112 participants were included in the ITT population. During follow-up, seven participants discontinued the study drug but remained on the study, and seven others discontinued follow-up. According to FDA Snapshot analysis, at W24 and W48, 90/112, (80.4%; 95% CI: 71.8-87.3) and 95/112 (84.8%; 95% CI: 76.8-90.9) of participants achieved pVL < 50 copies/mL, respectively. The protocol-defined virological failure (PDVF, 2 consecutive pVL ≥ 50 copies/mL as of W24) was observed in 11/112 (9.8%) at W24 and 14/112 (12.5%) at W48. No emergent resistance-associated mutation was detected in those with PDVF at W24 and W48. BIC/FTC/TAF was well tolerated through to W48, with a low incidence of grade 3-4 adverse events (15/100 person-years). Patient opinion of same-day treatment initiation and continuing BIC/FTC/TAF was very favourable., Conclusions: These results suggest that BIC/FTC/TAF is safe, effective and well accepted for same-day initiation., (© The Author(s) 2023.

Objectives: Our objective was to identify missed opportunities for the use of pre-exposure prophylaxis (PrEP) in people with recently acquired HIV, factors associated with PrEP knowledge, and reasons for not using PrEP., Design: This was a French national cross-sectional multicentre study enrolling people diagnosed with recent HIV (incomplete Western blot or negative HIV test in the previous 6 months) in 28 HIV clinical centres. Data were gathered using a self-administered questionnaire (SAQ)., Method: We analysed missed opportunities for PrEP use via a retrospective prep cascade. Factors associated with prior knowledge of PrEP and reasons for PrEP non-use among those who knew about PrEP were described using univariate and multivariate logistic regression models., Results: Of the 224 eligible patients, 185 completed the SAQ and 168 (91%) were eligible for PrEP. Of these, 90% reported seeing at least one physician during the previous year, 26% received information about PrEP, and 5% used PrEP. Factors independently associated with a higher probability of knowing about PrEP were being a man who has sex with men, being aged 25-30 years (vs older), undergoing HIV screening at least once every semester (vs less often; odds ratio [OR] 4.11; 95% confidence interval [CI] 2.00-8.45), and practicing chemsex (OR 3.19; 95% CI 1.12-9.10). Fear of side effects and a low perceived risk of HIV infection were the two most common reasons for not using PrEP (N = 40 [33.33%] and N = 34 [28.3%], respectively)., Conclusions: We found two gaps in the retrospective PrEP cascade: insufficient provision of PrEP information by healthcare providers (mainly general practitioners) and low PrEP acceptability by informed, eligible patients. More diverse healthcare providers need to be involved in PrEP prescription, and at-risk people need to be sensitized to the risk of HIV infection., (© 2022 The Authors.

Background: Antimicrobial resistance to macrolides and fluoroquinolones in Mycoplasma genitalium (MG) among men who have sex with men (MSM) is worryingly high in high-resource countries. Data in Africa are lacking. We aimed to assess the burden of MG including the presence of resistance-associated mutations (RAMs) in MG among MSM using human immunodeficiency virus preexposure prophylaxis in Burkina Faso, Côte d'Ivoire, Mali, and Togo., Methods: MSM were included in a prospective cohort study (2017-2021). Molecular detection of MG in urine, anorectal, and pharyngeal samples was performed at baseline and after 6 and 12 months. Detection of RAMs to macrolides and fluoroquinolones was performed by sequencing the 23S ribosomal RNA, parC , and gyrA genes. A sample was found to be possibly resistant to fluoroquinolones if alterations were found in ParC position 83/87., Results: Of 598 participants, 173 (28.9%) were positive at least once for MG and global point-prevalence was 19.4%. Interestingly, 238 of 250 (95.2%) infections were asymptomatic and 72 of 138 MG infections with follow-up data (52.2%) cleared during the study. Only 1 macrolide RAM was found (0.6%). Prevalence of fluoroquinolones RAMs was 11.3% overall, ranging from 2.4% in Burkina Faso to 17.5% in Mali., Conclusions: Although MG was highly prevalent in these MSM, macrolide resistance was almost nonexistent. Nevertheless, >10% of the samples were possibly resistant to fluoroquinolones. Heterogeneity in the prevalence of fluoroquinolone RAMs between countries may be explained by different antimicrobial consumption in humans and animals., Competing Interests: Potential conflicts of interest.

Introduction: The SARS-CoV-2 pandemic led to the implementation of several non-pharmaceutical interventions (NPIs), from closings of bars and restaurants to curfews and lockdowns. Vaccination campaigns started hoping it could efficiently alleviate NPI. The primary objective of the "Indoor Transmission of COVID-19" (ITOC) study is to determine among a fully vaccinated population the relative risk of SARS-CoV-2 transmission during one indoor clubbing event. Secondary objectives are to assess the transmission of other respiratory viruses, risk exposure, and attitudes toward COVID-19 vaccination, health pass, and psychological impact of indoor club closing., Methods and Analysis: Four thousand four hundred healthy volunteers aged 18-49 years and fully vaccinated will be included in Paris region. The intervention is an 8-hour indoor clubbing event with no masks, no social distance, maximum room capacity, and ventilation. A reservation group of up to 10 people will recruit participants, who will be randomized 1:1 to either the experimental group (2,200 volunteers in two venues with capacities of 1,000 people each) or the control group (2,200 volunteers asked not to go to the club). All participants will provide a salivary sample on the day of the experiment and 7 days later. They also will answer several questionnaires. Virological analyses include polymerase chain reaction (PCR) of salivary samples and air of the venue, investigating SARS-CoV-2 and 18 respiratory viruses., Ethics and Dissemination: Ethical clearance was first obtained in France from the institutional review board (Comité de Protection des Personnes Ile de France VII - CPP), and the trial received clearance from the French National Agency for Medicines and Health Products (Agence National de Sécurité du Médicament - ANSM). The trial is supported and approved by The Agence Nationale Recherche sur le SIDA, les hépatites et maladies émergences (ANRS-MIE). Positive, negative, and inconclusive results will be published in peer-reviewed scientific journals., Trial Registration Number: IDR-CB 2021-A01473-38.

We investigated the rate and predictors of ineffective HIV protection in men who have sex with men (MSM) taking pre-exposure prophylaxis (PrEP) in a prospective cohort study from November 2017 to November 2020 in Mali, Côte d'Ivoire, Burkina Faso, and Togo. MSM had to be 18 years or older and at high risk of HIV infection to participate. They also received a comprehensive sexual health prevention package, including PrEP, in community-based clinics as part of the cohort study. Using socio-behavioral/clinical data, HIV protection during their most recent anal intercourse with a male partner was categorized as effective or ineffective (i.e., incorrect PrEP adherence and no condom use). Seventeen percent (500/2839) of intercourses were ineffectively protected for the 520 study participants. Predictors of ineffective HIV protection included being an event-driven user with financial difficulties, having a high alcohol misuse score, and not being a member of a community association. PrEP programs in West Africa must be tailored to socially vulnerable MSM who struggle to adopt PrEP., (© 2022.

Loss to follow-up (LTFU) from HIV pre-exposure prophylaxis (PrEP) care compromises the goal of HIV elimination. We investigated the proportion of LTFU and associated risk factors among men who have sex with men (MSM) enrolled in a PrEP demonstration project in Burkina Faso, Côte d'Ivoire, Mali, and Togo. CohMSM-PrEP, a prospective cohort study, was conducted between November 2017 and June 2021 in community-based clinics. MSM aged 18 years or older at substantial risk of HIV infection received a comprehensive prevention package, including PrEP and peer education. LTFU was defined as not returning to the clinic for six months. Associated risk factors were investigated using a time-varying Cox's model. Of 647 participants followed up for a median time of 15 months, 372 were LTFU (57.5%). LTFU was associated with younger age (adjusted hazard ratio [95% Confidence Interval]; 1.50 [1.17-1.94]), unemployment (1.33 [1.03-1.71]), depression (1.63 [1.12-2.38]), and perceiving no HIV risk with stable male partners (1.61 [1.23-2.10]). Contacting peer educators outside of scheduled visits was protective (0.74 [0.56-0.97]). Our findings show that LTFU from PrEP care in West African MSM is a major challenge to achieving HIV elimination, but that the involvement of peer educators in PrEP delivery helps to limit LTFU by providing users with adequate support.

Background: Multiple barriers compromise pre-exposure prophylaxis (PrEP) engagement (i.e., use and adherence) in men who have sex with men (MSM). In low/middle-income countries, little is known about PrEP engagement in this population. In West Africa, the CohMSM-PrEP study was one of the rare interventions providing PrEP to MSM. We estimated PrEP use and correct adherence rates in CohMSM-PrEP, together with associated factors over time.  METHODS: CohMSM-PrEP recruited MSM in four community-based clinics in Mali, Côte d'Ivoire, Burkina Faso, and Togo. Quarterly follow-up included collecting socio-behavioral data, and providing a comprehensive HIV prevention package, PrEP (daily or event-driven), and peer educator (PE)-led counselling. Using repeated measures, multivariate generalized estimating equations models were used to identify factors associated with self-reported i) PrEP use and ii) correct PrEP adherence during participants' most recent anal intercourse (defined as four pills/week for daily users and 2 + 1 + 1 for event-driven users)., Results: Five hundred twenty participants were included with a median follow-up time of 12 months (IQR 6-21). Of the 2839 intercourses declared over the follow-up period, PrEP use was self-reported for 1996 (70%), and correct PrEP adherence for 1461 (73%) of the latter. PrEP use was higher in participants who also attended participating clinics outside of scheduled visits (adjusted odds ratio (aOR) [95% Confidence Interval, CI], p-value; 1.32[1.01-1.71], 0.040), and in those who practiced condomless anal sex (1.86[1.54-2.24], < 0.001). Correct adherence was higher in those who often contacted PE outside of scheduled visits (2.16[1.01-4.64], 0.047) and in participants who adopted receptive/versatile sexual positions with stable partners (1.36[1.03-1.81], 0.030). Instead, after an interaction effect between financial situation and regimen was tested, it was lower in event-driven users with a difficult/very difficult financial situation (comfortable/just making ends meet & daily, 4.19[2.56-6.86], < 0.001; difficult/very difficult & daily, 6.47[4.05-10.30], < 0.001; comfortable/just making ends meet & event-driven, 1.63[1.22-2.17], 0.001), and in participants who felt alone (0.76[0.58-0.99], 0.042)., Conclusions: Community-based clinic attendance and PE contact outside of scheduled visits were both associated with higher PrEP engagement, but some socially and economically marginalized participants struggled with adherence. As scale-up continues in West Africa, we recommend implementing community-based interventions and providing extra support for vulnerable users to ensure adequate PrEP engagement., (© 2022.

Objective: The present study aimed to understand what factors can lead to late HIV diagnosis of illegal gold miners at French Guiana's border with Brazil., Design: An exploratory qualitative study with in-depth interviews and observations was conducted between November 2019 and February 2020., Setting: The study was conducted in the main medical healthcare service and two non-governmental organisation premises in the Oyapock border region, which is a supply area for illegal gold mining sites., Participants: Fifteen people living with HIV diagnosed with CD4 count <350 cells 10 6 /L were interviewed. Seven women and eight men participated; they were between 31 and 79 years old, and the median time since HIV diagnosis was 6 years. Eight had links to illegal gold mining., Findings: Three key themes for late HIV diagnosis emerged: (1) the presence of economic and political structural factors which constitute risks for this illegal activity, specifically the repression of gold mining sites by French Armed Forces and the distance from healthcare facilities; (2) representations of the body and health, related to the living conditions of this population; prioritisation of health emergencies and long-term self-medication; and (3) gender roles shaping masculinity and heterosexuality contributing to a perception of not being at risk of HIV and delaying testing., Conclusion: This study highlights structural, group-based and individual factors that reduce access to HIV testing and healthcare in general for a population of migrant workers in an illegal gold mining area. Faced with harsh living conditions and state repression, these workers develop a vision of health which prioritises the functionality of the body. Associated with gender roles which are partly shaped both by the mining activity and its geographical location, this vision can lead to late HIV diagnosis., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Background: There are few data available regarding the use of on-demand pre-exposure prophylaxis (PrEP) for HIV prevention. We aimed to assess PrEP effectiveness, adherence, and safety in adults using daily or on-demand PrEP., Methods: We conducted a prospective observational cohort study (ANRS PREVENIR) at 26 sites in the Paris region, France. We enrolled HIV-negative adults (aged ≥18 years) at high risk of HIV infection who were starting or continuing PrEP. PrEP was prescribed as a fixed-dose combination of tenofovir disoproxil and emtricitabine (245 mg and 200 mg, respectively, per pill). PrEP could be prescribed as a daily regimen with one pill per day or, in men who have sex with men (MSM) or in transgender women who have sex with men, as an on-demand regimen following the IPERGAY dosing recommendation. At enrolment and every 3 months thereafter, participants were tested for HIV and provided information regarding the PrEP dosing regimen used. Adherence to PrEP was assessed by self-report and by tenofovir diphosphate concentrations in dried blood spots. The primary outcome of HIV-1 incidence was assessed using Poisson regression among participants who started PrEP. This study is registered with ClinicalTrials.gov, NCT03113123, and EudraCT, 2016A0157744., Findings: Between May 3, 2017, and May 2, 2019, 3082 people were assessed for eligibility and 3065 participants were enrolled. 3056 (99·7%) of 3065 participants reported using PrEP and were included in the analyses. The median age was 36 years (IQR 29-43), 1344 (44·0%) of 3056 participants were PrEP-naive, and 3016 (98·7%) were MSM. At enrolment, 1540 (50·5%) of 3049 participants opted for daily PrEP dosing and 1509 (49·5%) opted for on-demand PrEP dosing; these proportions remained stable during follow-up. Median follow-up was 22·1 months (IQR 15·9-29·7) and incidence of study discontinuation was 17·6 participants (95% CI 16·5-18·7) per 100 person-years. At the data cutoff on Sept 30, 2020, there had been six HIV-1 seroconversions (three participants using daily PrEP and three using on-demand PrEP; all were MSM) over 5623 person-years. Overall HIV-1 incidence was 1·1 cases (95% CI 0·4-2·3) per 1000 person-years, and did not differ between participants using daily PrEP and those using on-demand PrEP (incidence rate ratio 1·00, 95% CI 0·13-7·49; p=0·99). Four participants (two using daily PrEP and two using on-demand PrEP) discontinued PrEP due to treatment-related adverse events (nausea [n=2], vomiting and diarrhoea [n=1], and lumbar pain [n=1])., Interpretation: In this study, which enrolled mainly MSM, HIV-1 incidence on PrEP was low and did not differ between participants using daily PrEP and those using on-demand PrEP. On-demand PrEP therefore represents a valid alternative to daily PrEP for MSM, providing greater choice in HIV prevention., Funding: ANRS/Maladies Infectieuses Emergentes, Gilead Sciences, SIDACTION, and Région Ile de France., Translation: For the French translation of the abstract see Supplementary Materials section., Competing Interests: Declaration of interests J-MM reports receiving support as an advisor for Gilead Sciences, Merck, Janssen, and ViiV; and research grants from Gilead Sciences.

Objectives: We aimed to assess among men who have sex with men (MSM) risk factors for HIV infection, to identify those who require urgent pre-exposure prophylaxis (PrEP) prescription., Methods: All participants enrolled in the placebo arm of the ANRS IPERGAY trial, or infected between screening and day 0, were included. Baseline characteristics were described and HIV incidence rate ratios (RRs) were estimated with their 95% CIs., Results: 203 MSM were included with a median follow-up of 9 months. During the study period, 16 participants acquired HIV infection while not receiving tenofovir disoproxil and emtricitabin (TDF/FTC) over 212.4 person-years (PYs) of follow-up (incidence rate 7.5/100 PYs, 95% CI: 4.3 to 12.2). Being enrolled in Paris was associated with a significant increased risk of HIV infection (RR: 4.1; 95% CI: 1.1 to 28.3). A high number of sexual partners in prior 2 months (≥10 vs < 5) and of condomless receptive anal sex episodes in prior 12 months (>5 vs <5) were strong predictors for HIV acquisition (RR: 10.6 (2 to 260.2) and 3.3 (1.2 to 10.2), respectively). Those who reported more often or only receptive sexual practices were also at increased risk (RR: 9.8 (2.0 to 246.6)). The use of recreational drugs in prior 12 months, especially gamma hydroxybutarate/gamma butyrolactone (RR: 5.9; 95% CI: 2 to 21.7), was associated with a significantly increased risk of HIV acquisition even after adjustment for sexual practices., Conclusions: MSM who have frequent condomless receptive anal sex and multiple partners, or use recreational drugs should be targeted in priority for PrEP prescription especially if they live in an area with a high prevalence of HIV infection., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Objective: High rates of sexually transmitted infections (STIs) have been reported among pre-exposure prophylaxis (PrEP) users. We wished to assess the incidence and risk factors for recurrent STIs., Design: The ANRS IPERGAY trial was a prospective study investigating PrEP among MSM and transgender women in outpatient clinics in France and Canada. In all, 429 participants were enrolled, offered up to 4 years of PrEP and screened for bacterial STIs (syphilis, chlamydia and gonorrhea) at baseline and every 6 months., Methods: STIs incidence was calculated yearly. Cox proportional hazards model regression was used to explore associations between participants characteristics at baseline and recurrent STI during follow-up., Results: Over a median follow-up of 23 months, bacterial STI incidence was 75, 33, 13, 32 and 30 per 100 person-years for all STIs, rectal STIs, syphilis, gonorrhea and chlamydia, respectively. STI incidence significantly increased from the first year to the fourth year of the study (55 vs. 90 per 100 person-years, P  < 0.001). During the study period, 167 participants (39%) presented with more than one bacterial STIs which accounted for 86% of all STIs. Baseline risk factors associated with recurrent STIs in a multivariate analysis were an STI at baseline [hazards ratio: 1.48 (95% confidence interval (CI): 1.06-2.07), P  = 0.02], more than eight sexual partners in prior 2 months [hazards ratio: 1.72 (95% CI: 1.21-2.43), P  = 0.002] and the use of gamma-hydroxybutyrate [hazards ratio: 1.66 (95% CI: 1.16-2.38), P  = 0.005]., Conclusion: STI incidence was high and increased over time. Most STIs were concentrated in a high-risk group that should be targeted for future interventions., (Copyright © 2022 Wolters Kluwer Health, Inc. All rights reserved.)

Combination HIV prevention covers a range of biomedical, behavioral, and socio-structural interventions. Despite the growing availability of pre-exposure prophylaxis (PrEP), it is not always accessible in European Centre for Disease Prevention and Control reporting countries and may not meet the needs of all at-risk populations. Based on the Flash! PrEP in Europe data, multiple correspondence analysis and hierarchical clustering were used to identify patterns in HIV prevention strategies among 9980 men who have sex with men (MSM). PrEP interest was evaluated among four identified clusters: (A) "high condom use, sometimes Treatment as Prevention (TasP)"; (B) "mix of methods, infrequent condom use"; (C) "high condom use, tendency to choose partners based on serological status" and (D) "moderate use of condoms mixed with other prevention strategies". Clusters B and D had higher PrEP interest. These results suggest that MSM use a range of behavioral and biomedical risk reduction strategies that are often combined. On-demand PrEP may meet the needs of MSM who infrequently use condoms and other prevention methods., (© 2022.

Background: Despite great progress in antiretroviral treatment (ART) access in recent decades, HIV incidence remains high in sub-Saharan Africa. We investigated the role of individual and healthcare supply-related factors in HIV transmission risk in HIV-positive adults enrolled in 19 HIV services in the Centre and Littoral regions of Cameroon., Methods: Factors associated with HIV transmission risk (defined as both unstable aviremia and inconsistent condom use with HIV-negative or unknown status partners) were identified using a multi-level logistic regression model. Besides socio-demographic and behavioral individual variables, the following four HIV-service profiles, identified using cluster analysis, were used in regression analyses as healthcare supply-related variables: 1) district services with large numbers of patients, almost all practicing task-shifting and not experiencing antiretroviral drugs (ARV) stock-outs (n = 4); 2) experienced and well-equipped national reference services, most practicing task-shifting and not experiencing ARV stock-outs (n = 5); 3) small district services with limited resources and activities, almost all experiencing ARV stock-outs (n = 6); 4) small district services with a wide range of activities and half not experiencing ARV stock-outs (n = 4)., Results: Of the 1372 patients (women 67%, median age [Interquartile]: 39 [33-44] years) reporting sexual activity in the previous 12 months, 39% [min-max across HIV services: 25%-63%] were at risk of transmitting HIV. The final model showed that being a woman (adjusted Odd Ratio [95% Confidence Interval], p-value: 2.13 [1.60-2.82], p<0.001), not having an economic activity (1.34 [1.05-1.72], p = 0.019), having at least two sexual partners (2.45 [1.83-3.29], p<0.001), reporting disease symptoms at HIV diagnosis (1.38 [1.08-1.75], p = 0.011), delayed ART initiation (1.32 [1.02-1.71], p = 0.034) and not being ART treated (2.28 [1.48-3.49], p<0.001) were all associated with HIV transmission risk. Conversely, longer time since HIV diagnosis was associated with a lower risk of transmitting HIV (0.96 [0.92-0.99] per one-year increase, p = 0.024). Patients followed in the third profile had a higher risk of transmitting HIV (1.71 [1.05-2.79], p = 0.031) than those in the first profile., Conclusions: Healthcare supply constraints, including limited resources and ARV supply chain deficiency may impact HIV transmission risk. To reduce HIV incidence, HIV services need adequate resources to relieve healthcare supply-related barriers and provide suitable support activities throughout the continuum of care., Competing Interests: The authors have declared that no competing interests exist.

Background: Lockdown measures during the first wave of the COVID-19 pandemic in France led to serious public health concerns over people who use illicit drugs, especially in terms of mental health. We assessed changes in cannabis use during the first lockdown in France among daily cannabis users and associated correlates., Methods: CANNAVID is a French, national, cross-sectional web-based survey, conducted from 17 April to 11 May 2020. Daily cannabis users aged ≥ 18 years and living in France were invited to participate through advertisements. Respondents completed an ad hoc questionnaire on a dedicated online platform. We analyzed changes in cannabis use during the first lockdown (i.e., stopped, decreased, unchanged, or increased) and performed a multinomial logistic regression analysis to evaluate correlates of these changes., Results: Of the 4019 participants, 74.0% were men. Median age was 27 years (interquartile range: 22-37). With regard to cannabis use, 293 (7.3%) persons stopped, 1153 (28.7%) decreased, 1146 (28.5%) did not change, and 1427 (35.5%) increased their use during the lockdown. A multinomial logistic regression model revealed several sociodemographic, behavioral and health-related factors associated with changes in cannabis use. Compared with participants with an unchanged level of cannabis use during the lockdown, those who increased and those who stopped cannabis use were more likely to have increased tobacco and alcohol use and to have experienced depression and sleep disorders intensification. Those who stopped cannabis use were also more likely to have increased benzodiazepine use and to have experienced pain increase during lockdown., Conclusions: France's first COVID-19-related lockdown had a differential impact on daily cannabis users' consumption patterns. Most study respondents reported changes to their cannabis consumption pattern. Those who reported a stable cannabis use were more likely to report fewer negative changes. Specific interventions are needed for this population, as well as research to assess the long-term impacts of these changes., (© 2022. The Author(s).)

Objective: Although men who have sex with men (MSM) are at high risk of STI, their access to tailored healthcare services remains limited in West Africa. We assessed the change in STI symptoms incidence over time among MSM enrolled in a quarterly HIV prevention and care programme in four cities in Burkina Faso, Côte d'Ivoire, Mali and Togo., Methods: We performed a prospective cohort study in MSM followed up between 2015 and 2019. Men aged over 18 who reported anal sex with another man within the previous 3 months were offered quarterly syndromic diagnosis and treatment for STI, as well as HIV testing, peer-led counselling and support. Condoms and lubricants were also provided. The change in STI symptoms incidence during follow-up was investigated using a non-parametric trend test and mixed-effect Poisson regression models., Results: 816 participants were followed for a total duration of 1479 person-years. 198 participants (24.3%) had at least one STI symptom during follow-up. Overall, STI symptoms incidence was 20.4 per 100 person-years (95% CI 18.4 to 22.6), ranging from 15.3 in Abidjan to 33.1 in Ouagadougou (adjusted incidence rate ratio (aIRR) 2.39, 95% CI 1.55 to 3.69, p<0.001). STI symptoms incidence was 16.8 and 23.0 per 100 person-years in HIV-positive and HIV-negative participants, respectively (aIRR 0.77, 95% CI 0.57 to 1.04, p=0.087). STI symptoms incidence decreased significantly from 29.9 per 100 person-years in the first 6 months to 8.6 at 30-35 months of follow-up (aIRR per 6-month increase 0.84, 95% CI 0.77 to 0.92, p<0.001)., Conclusion: STI symptoms incidence decreased over time but the overall burden of STI appeared to be very high in MSM followed up in West Africa. STI services including counselling, diagnosis and treatment should be reinforced. Laboratory tests that allow accurate diagnosis of STI are required. Strengthening STI services will be critical for controlling the HIV and STI epidemics in this vulnerable population and in the general population., Trial Registration Number: NCT02626286., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Observing sexual behaviour change over time could help develop behavioural HIV prevention interventions for female sex workers in Zambia, where these interventions are lacking. We investigated the evolution of consistent condom use among female sex workers and their clients and steady partners. Participants were recruited into an HIV incidence cohort from 2012 to 2017. At each visit, women received HIV counselling and testing, screening for sexually transmitted infections (STIs) and free condoms. Our outcome was reported consistent (100%) condom use in the previous month with steady partners, repeat clients, and non-repeat clients. Consistent condom use at baseline was highest with non-repeat clients (36%) followed by repeat clients (27%) and steady partners (17%). Consistent condom use between baseline and Month 42 increased by 35% with steady partners, 39% with repeat clients and 41% with non-repeat clients. Access to condoms, HIV/STI counselling and testing promoted positive sexual behaviour change., (© 2021.

In 2020, the COVID-19 health crisis affected all regions of the world, not sparing people already vulnerable to other viral epidemics such as HIV or HCV and/or those in precarious or socially marginalized situations. This is particularly the case for drug users or sex workers.Coalition PLUS, a network of associations fighting against HIV and viral hepatitis which defends and promotes the community-based approach, and its partners, have set up a multi-country community-based research project aimed at documenting the impact of the health crisis on the fight against HIV and viral hepatitis (key populations and community workers/activists), as well as the community responses put in place (EPIC survey).The objective of this paper is to reflect on the implementation of this community-based research study during the COVID-19 health crisis, and in particular the unforeseen difficulties to which the community-based research process had to confront and adapt. The goal is to draw lessons on what worked (and what did not work) in order to capitalize on community-based research practices during this pandemic and subsequently, facilitate the implementation of new research projects in similar contexts.

Chemsex-the use of drugs in a sexual context-has been associated with more at-risk sexual practices and substance-related complications in men who have sex with men (MSM). To date, no study has focused on the impact of France's first coronavirus disease 2019 (COVID-19)-related lockdown on the mental health and drug/alcohol use of MSM who practice chemsex. We implemented a web-based survey of 9,488 MSM living in France in June 2020 (after the country's first COVID-19 lockdown). Specifically, we first compared the subpopulation of MSM who self-reported practicing chemsex during their most recent sexual intercourse (defined as "chemsexers") with other MSM, using five outcomes: increased 1/tobacco use, 2/alcohol use, and 3/other psychoactive drug use. 4/using psychotropic medication during the lockdown, and finally 5/psychological distress. We then analyzed the outcomes' associations with the main explanatory variable "chemsexer," after adjusting for all relevant variables. Among 7,195 MSM who had sexual intercourse with a man during the previous 6 months, 359 participants (5%) were identified as "chemsexers." Multivariable analyses showed that during the first lockdown period, chemsexers were significantly more likely than non-chemsexers to have increased their use of tobacco, alcohol, and other psychoactive substances. Chemsexers were also more likely to have used psychotropic medication and to have experienced psychological distress during the previous month. Given the ongoing COVID-19 pandemic in France and worldwide, this finding highlights the need to develop psychosocial interventions and harm reduction services for MSM chemsexers, potentially via mobile health.

Introduction: Transgender identity is poorly accepted in France, and data on living conditions and the daily difficulties transgender people encounter are scarce. This lack of data reinforces their invisibility in social life, contributes to their stigmatisation and probably increases the burden of HIV infection, especially for HIV-positive transgender people (TRHIV). The main objective of the community-based research study ANRS Trans&HIV is to identify personal and social situations of vulnerability in TRHIV, the obstacles they encounter in terms of access to and retention in medical care, and their gender affirmation and HIV care needs., Methods and Analysis: ANRS Trans&HIV is a national, comprehensive, cross-sectional survey of all TRHIV currently being followed in HIV care units in France. TRHIV women are exclusively included in the quantitative component, and TRHIV men in the qualitative component. Data are collected by community-based interviewers and will be analysed to explore patient care pathways and living conditions in the TRHIV population with regard to gender affirmation and HIV. Data collection began in October 2020 and should be completed in December 2021. The statistical analyses techniques used will be adapted to each of the study's objectives and to the type of data collected (cross-sectional ( questionnaires ) and retrospective ( biographical trajectory )). The study's results will provide a greater understanding of TRHIV health needs in order to suggest possible national recommendations for comprehensive HIV and gender affirmation medical care., Ethics and Dissemination: ANRS Trans&HIV was approved by Inserm's Ethical Evaluation Committee (no 20-694 on 12 May 2020) and is registered with the National Commission on Informatics and Liberty under number 2518030720. Potential participants are informed about the study through an information note provided by their attending HIV physician. All results published in peer-reviewed journals will be disseminated to the HIV transgender community, institutional stakeholders and healthcare providers., Trial Registration Number: NCT04849767., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Background: Men who have sex with men (MSM) are at high risk of human papillomavirus (HPV) infection. We assessed (i) the prevalence of high-risk HPV (HR-HPV) infection and associated factors, and (ii) the prevalence of vaccine-preventable HPV infections in MSM in Burkina Faso, Côte d'Ivoire, Mali, and Togo., Methods: A cross-sectional study was conducted in 2017-2018 among MSM ≥18 years old followed in community-based clinics. HPV infection was investigated in oral and anal samples using the e-BRID system. Factors associated with HR-HPV infection were identified using multivariate logistic regressions., Results: Among 631 participants, 425 were HIV-negative and 206 HIV-positive. HR-HPV prevalence ranged from 9.2% to 34.8% in the former, and 33.3% to 71.0% in the latter, according to the study country. In multivariate analysis, HIV infection (adjusted odds ratio (aOR) 3.61, 95% confidence interval (CI) 2.48-5.27) and study country (4.73, 2.66-8.43 for Mali; 3.12, 1.68-5.80 for Burkina Faso; 3.51, 1.92-6.42 for Togo) were associated with HR-HPV infection. Other associated factors were low educational level, self-defined homosexual identity, and condomless anal sex. The prevalence of infections which can be prevented with bivalent, quadrivalent, and nonavalent vaccines was 5.9, 27.1, and 34.6% in HIV-negative participants, and 18.9, 43.7, and 54.9% in HIV-positive participants, respectively., Conclusions: HR-HPV prevalence was very heterogeneous between the study countries in both HIV-negative and HIV-positive MSM. Vaccine-preventable HPV infections predominated. Vaccination should be proposed to young MSM to reduce the burden of HPV infection in this vulnerable population and their female partners in West Africa., (© The Author(s) 2021.
