Abstract

Abstract With a national prevalence of 0.9%, Burundi is close to achieving UNAIDS’ 2025 targets. Despite this, different types of crises periodically disrupt its HIV health services. The community-based program EPIC measured the impact of the COVID-19 health crisis on people living with HIV (PLHIV) in Burundi in 2021. Specifically, it assessed ART interruption and associated factors since the beginning of the pandemic. The study questionnaire was administered to PLHIV in three cities between October and November 2021. Participants were recruited using convenience sampling. Logistic regression models helped identify factors associated with ART interruption. Of the 317 respondents, 37 (11.7%) reported interruption. The majority (79.2%) self-identified as belonging to key populations. Interruption was significantly associated with: fewer HIV medical follow-up visits (adjusted Odds Ratio, aOR = 7.80, p = 0.001) and forced HIV status disclosure (aOR = 4.10, p = 0.004). It was inversely associated with multi-month ART dispensing (aOR = 0.36, p = 0.017) since the beginning of the pandemic and the perception of not having been sufficiently informed by the HIV medical team about the risk of COVID-19 infection (aOR = 0.11, p

Abstract

BackgroundInformation 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. ObjectiveThis 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. MethodsA 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. ResultsFrom 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). ConclusionsThe 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.

Abstract

International audience; Background HIV pre-exposure prophylaxis (PrEP) data in men who have sex with men (MSM) in west Africa are essential to guide its large-scale implementation. We assessed the uptake of event-driven and daily PrEP, HIV incidence, and changes over time in sexual behaviours and prevalence of bacterial sexually transmitted infections (STIs) in MSM in Burkina Faso, Côte d'Ivoire, Mali, and Togo. Methods We did a prospective cohort study from Nov 20, 2017, to April 14, 2020, in four community-based clinics in Abidjan (Côte d'Ivoire), Bamako (Mali), Lomé (Togo), and Ouagadougou (Burkina Faso). Participants were MSM aged 18 years or older at substantial risk of HIV infection. Participants could choose between event-driven (2+1+1 dosing) and daily oral PrEP (tenofovir disoproxil fumarate 300 mg plus emtricitabine 200 mg), switch regimen, and discontinue or restart PrEP. We compared HIV incidence in this study with that of the same cohort before the availability of PrEP (CohMSM). Statistical analysis included the Kaplan-Meier method and mixed-effects regression models. This study is registered with ClinicalTrials.gov, NCT03459157. Findings We followed up 598 participants for a total of 743•6 person-years. At enrolment, 445 (74%) of 598 participants chose event-driven PrEP and 153 (26%) of 598 chose daily PrEP. 60 (13%) of 445 and 65 (42%) of 153 partici pants switched PrEP regimen at least once (p

Abstract

BACKGROUND: Sexual transmission of hepatitis C virus (HCV) is uncommon, yet documented among men who have sex with men (MSM), primarily among those with human immunodeficiency virus (HIV). METHODS: In the HIV Prevention Trials Network 078 study (HPTN 078), which assessed an integrated strategy to achieve HIV viral suppression, 1305 MSM were screened across 4 geographically diverse US cities. At screening, demographic/behavioral/psychosocial questionnaires were completed, along with HIV and HCV testing. Multivariable logistic regression was used to evaluate associations with HCV antibody positivity. RESULTS: Among the 1287 (99%) of the MSM with HCV antibody results, the median age was 41, 69% were black, 85% had a high school education or more, 35% were employed, 70% had HIV, and 21% had undergone substance use counseling. The median lifetime number of male sexual partners was 17 (interquartile range, 6–50), and 246 (19%) were HCV antibody positive. HCV antibody positivity was high in MSM with HIV (20%) and MSM without HIV (17%) (P = .12) and was higher in those receiving substance use counseling (36%) than in those who had not (15%) (P ≤ .01). Substance use counseling (odds ratio, 2.51; 95% confidence interval, 1.80–3.51) and unstable housing (2.16; 1.40–3.33) were associated with HCV antibody positivity. CONCLUSIONS: Nearly 1 in 5 MSM screened for HPTN 078 have been infected with HCV. The prevalence is high regardless of HIV status and is high even in those who did not undergo substance use counseling. In HIV burden networks, high HCV infection prevalence may occur in MSM without HIV. As implementation of preexposure prophylaxis expands and condom use declines, routine HCV counseling and screening among MSM are important.

Abstract

International audience; Objective: The study aimed to explore longitudinal interactions between homonegativity and sexual behaviors with female partners among HIV-negative West African men who have sex with men and women (MSMW).Design and method: The community-based cohort CohMSM ANRS 12324 - Expertise France enrolled MSM in Togo, Burkina Faso, Côte d'Ivoire and Mali. Sociobehavioral data were collected every 6 months. Using 30-month follow-up data, a multiprobit analysis was performed to investigate the relationship between psychosocial and behavioral variables ex-ante (t - 1) and ex-post (t).Results: MSMW (n = 326) accounted for half of all participants in CohMSM. They reported inconsistent condom use with women in 39% of visits. Perceived and internalized homonegativity at t - 1 tended to lead to sexual violence toward women at t (P < 0.1), which was associated with inconsistent condom use with them at t (P < 0.05).Conclusion: Given the high HIV prevalence in West African MSM, widespread condom-less sex with women in MSMW, and the aggravating effect of social and internalized homonegativity, more research in the MSMW subpopulation is needed to assess the risk of HIV bridging to women and to design support activities.

Abstract

International audience; Background: In West Africa, few HIV services target men who have sex with men (MSM). In 2015, the interventional cohort CohMSM started offering a community-based prevention package for MSM. Participants expressed interest in pre-exposure prophylaxis (PrEP) and their eligibility was demonstrated. In 2017, PrEP was added to services already offered as part of a new program, CohMSM-PrEP, which recruited CohMSM participants and new participants. We aimed to determine whether the introduction of PrEP as an additional prevention tool influenced the type of participant signing up for CohMSM-PrEP.Methods: CohMSM-PrEP recruited HIV-negative MSM in community-based clinics in Mali, Cote d'Ivoire, Burkina Faso, and Togo. Quarterly follow-up included free clinical examinations, PrEP, HIV/sexually transmitted infection screening, peer education, condoms, and lubricants. Sociobehavioral data were collected every 3 months using face-to-face questionnaires. Our outcome was participant type: new participants vs CohMSM participants. Logistic regression was performed to identify the factors associated with being a new participant.Results: Of the 524 MSM included in CohMSM-PrEP, 41% were new participants. After adjustment, multivariate analysis showed they were more socioeconomically disadvantaged with financial insecurity, social isolation-including isolation within the MSM community-and riskier sexual practices.Conclusion: The introduction of PrEP as an additional prevention tool and the use of peer-based outreach services over time influenced the type of participant signing up for a community-based HIV prevention cohort in West Africa. Adding these elements to existing interventions in Sub-Saharan Africa could be the key to reaching MSM marginalized from HIV prevention and care programs.

Abstract

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.
