RESUMO

Uptake of PrEP remains suboptimal, especially in the Southern United States. Same-day or "Rapid PrEP Initiatives" (RPIs) in sexual health centers (SHCs) could facilitate access and overcome barriers to PrEP. We studied the adaptation of an RPI from Denver, Colorado to an SHC in New Orleans, Louisiana. Through focus group discussions (FGDs) with local SHC staff and PrEP providers, we developed a preliminary RPI model. In 5 FGDs with SHC clients referred for or taking PrEP, we gathered adaptation recommendations and feedback on model acceptability, feasibility, and utility. Providers and clients voiced unanimous support for the RPI. Clients favored the ease of same-day PrEP initiation and emphasized a desire for navigational support, financial counseling, and integration of PrEP care with their other clinical needs. Clients recommended that SHC providers discuss PrEP and HIV with all patients, regardless of providers' perception of risk. Next steps include small-scale implementation and evaluation.


Client Perspectives on the Development of a Same-Day PrEP Initiation Protocol at a Sexual Health Center in New Orleans, LouisianaUptake of PrEP remains low, especially in the Southern United States. Same-day or "Rapid PrEP Initiatives" (RPIs) in sexual health centers (SHCs) could facilitate access and overcome barriers to PrEP. RPIs provide eligible clients with an opportunity to start PrEP on the same day they receive screening for sexually transmitted infections.

RESUMO

Background: Novel HIV pre-exposure prophylaxis (PrEP) methods including a potential future HIV vaccine, will increase prevention options for adolescent girls and young women (AGYW) at high risk of HIV infection in Eastern and Southern Africa, yet data on AGYW's preferences for various PrEP methods is limited. We investigated preferences for five biomedical PrEP methods (oral, injectable, vaginal ring, implant, HIV vaccine) among 14-24-years-old AGYW in Kampala, Uganda. Methods: From January to December 2019, we conducted a mixed methods study including 265 high-risk AGYW. After receiving two education sessions on the five PrEP methods, participants were asked about their "most preferred PrEP method." Multinomial logistic regression (oral PrEP as reference category) was used to determine participant characteristics associated with method preference. Results are presented as adjusted relative risk ratios (aRRR) with 95% confidence intervals (CI). In-depth interviews were conducted with 20 selected participants to examine reasons influencing PrEP preferences and suggestions for method improvements. Transcripts were analyzed thematically. Results: Participants preferred methods were: HIV vaccine (34.7%), oral PrEP (25.7%), injectable PrEP (24.9%), PrEP implant (13.6%), and vaginal ring (1.1%). Preference for injectable PrEP increased with every year of age (aRRR 1.22; 95% CI 1.04-1.44) and among participants with chlamydia or gonorrhoea (aRRR 2.53; 95% CI 1.08-5.90), while it was lower among participants having sexual partner(s) living with HIV or of unknown HIV status (aRRR 0.30; 95% CI 0.10-0.91). Preference for PrEP implants also increased with age (aRRR 1.42; 95% CI 1.14-1.77) and was strong among participants having ≥10 sexual partners in the past 3 months (aRRR 3.14; 95% CI 1.16-8.55), while it was lower among those with sexual partner(s) living with HIV or of unknown HIV status (aRRR 0.25; 95% CI 0.07-0.92). PrEP method preference was influenced by product attributes and prior experiences with similar product forms commonly used in health care. Conclusion: AGYW have varied preferences for biomedical PrEP method and those with higher sexual behavioral risk prefer long-acting methods. As we anticipate more available PrEP options, oral PrEP use should be supported among AGYW, especially for those with sexual partners living with HIV or of unknown HIV status.

RESUMO

INTRODUCTION: Despite the widespread use of pre-exposure prophylaxis (PrEP) in preventing human immunodeficiency virus (HIV) transmission, scant information on HIV drug resistance mutations (DRMs) has been gathered over the past decade. This review aimed to estimate the pooled prevalence of pre-exposure prophylaxis and its two-way impact on DRM. METHODS: We systematically reviewed studies on DRM in pre-exposure prophylaxis according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis 2020 guidelines. PubMed, Cochrane, and SAGE databases were searched for English-language primary studies published between January 2001 and December 2023. The initial search was conducted on 9 August 2021 and was updated through 31 December 2023 to ensure the inclusion of the most recent findings. The registration number for this protocol review was CRD42022356061. RESULTS: A total of 26,367 participants and 562 seroconversion cases across 12 studies were included in this review. The pooled prevalence estimate for all mutations was 6.47% (95% Confidence Interval-CI 3.65-9.93), while Tenofovir Disoproxil Fumarate/Emtricitabine-associated drug resistance mutation prevalence was 1.52% (95% CI 0.23-3.60) in the pre-exposure prophylaxis arm after enrolment. A subgroup analysis, based on the study population, showed the prevalence in the heterosexual and men who have sex with men (MSM) groups was 5.53% (95% CI 2.55-9.40) and 7.47% (95% CI 3.80-12.11), respectively. Notably, there was no significant difference in the incidence of DRM between the pre-exposure prophylaxis and placebo groups (log-OR = 0.99, 95% CI -0.20 to 2.18, I2 = 0%; p = 0.10). DISCUSSION: Given the constrained prevalence of DRM, the World Health Organization (WHO) advocates the extensive adoption of pre-exposure prophylaxis. Our study demonstrated no increased risk of DRM with pre-exposure prophylaxis (p > 0.05), which is consistent with these settings. These findings align with the previous meta-analysis, which reported a 3.14-fold higher risk in the pre-exposure prophylaxis group than the placebo group, although the observed difference did not reach statistical significance (p = 0.21). CONCLUSIONS: Despite the low prevalence of DRM, pre-exposure prophylaxis did not significantly increase the risk of DRM compared to placebo. However, long-term observation is required to determine further disadvantages of extensive pre-exposure prophylaxis use. PROSPERO Number: CRD42022356061.

RESUMO

This protocol presents a multilevel cluster randomized study in 24 communities in Cape Town, South Africa. The study comprises four specific aims. Aim 1, conducted during the formative phase, was to modify the original Couples Health CoOp (CHC) intervention to include antiretroviral therapy/pre-exposure prophylaxis (ART/PrEP), called the Couples Health CoOp Plus (CHC+), with review from our Community Collaborative Board and a Peer Advisory Board. Aim 1 has been completed for staging the trial. Aim 2 is to evaluate the impact of a stigma awareness and education workshop on community members' attitudes and behaviors toward young women and men who use AODs and people in their community seeking HIV services (testing/ART/PrEP) and other health services in their local clinics. Aim 3 is to test the efficacy of the CHC+ to increase both partners' PrEP/ART initiation and adherence (at 3 and 6 months) and to reduce alcohol and other drug use, sexual risk and gender-based violence, and to enhance positive gender norms and communication relative to HIV testing services (n = 480 couples). Aim 4 seeks to examine through mixed methods the interaction of the stigma awareness workshop and the CHC+ on increased PrEP and ART initiation, retention, and adherence among young women and their primary partners. Ongoing collaborations with community peer leaders and local outreach staff from these communities are essential for reaching the project's aims. Additionally, a manualized field protocol with regular training, fidelity checks, and quality assurance are critical components of this multilevel community trial for successful ongoing data collection.

RESUMO

BACKGROUND: Ukraine has implemented ambitious HIV-prevention programs since 1999 and began offering preexposure prophylaxis (PrEP) in 2017. Little is known about PrEP uptake and persistence in this setting. SETTING: We analyzed data from 40 facilities providing PrEP in 11 oblasts (regions) of Ukraine between October 2020 and February 2022. METHODS: We estimated the time between PrEP visits and conducted Kaplan-Meier analyses to estimate retention on PrEP stratified by sex, age, and key populations (KPs): men who have sex with men (MSM), people who inject drugs (PWID), sex workers (SW), discordant couples, and others vulnerable to HIV acquisition (DC/other). We used Cox regression to estimate the risk of PrEP discontinuation by KP group and sex, adjusting for age. RESULTS: Overall, 2033 clients initiated PrEP across regions; the majority (51%) were DC/other, 22% were MSM, 22% were PWID, and 5% were SW. The overall 3-month persistence was 52.3% (95% confidence interval [CI]: 49.9% to 54.8%) and was lowest among MSM (46.7%; 95% CI: 41.9% to 52.2%) and SW (25.9%; 95% CI: 18.2% to 36.9%) (P < 0.05 for differences by KP group). After adjusting for age, PrEP discontinuation was not statistically significantly different across groups, although female PWID tended to have the lowest discontinuation risk (adjusted hazard ratio [aHR] 0.59; 95% CI: 0.31 to 1.11) while male SW tended to have the highest risk (aHR 1.87, 95% CI: 0.57 to 6.11) compared with females in the DC/other group. CONCLUSION: Three-month PrEP persistence was low across KP groups, especially in SW. Further research examining the barriers and enablers of persistence by KPs is needed.

RESUMO

BACKGROUND: Acute HIV infection during pregnancy and in the postpartum period increases the risk of vertical transmission. The World Health Organization (WHO) has recommended preexposure prophylaxis for pregnant and postpartum women at risk of acquiring HIV. However, there are significant gaps between the actual practice and the ideal goal of preexposure prophylaxis implementation among pregnant and postpartum women. Therefore, it is important to determine what influences women's implementation of preexposure prophylaxis during pregnancy and in the postpartum period. This review aims to aggregate barriers and facilitators to preexposure prophylaxis implementation among pregnant and postpartum women. METHODS: A range of electronic databases, including PubMed, CINAHL Plus with Full Text, Embase, and Web of Science, were searched for potentially relevant qualitative studies. The search period extended from the establishment of the databases to March 16, 2023. This review used the ENTREQ (Enhancing transparency in reporting of qualitative research synthesis) statement to guide the design and reporting of qualitative synthesis. The methodological quality of the included studies was assessed using the Joanna Briggs Institute Critical Appraisal Checklist. The JBI meta-aggregation method was applied for guiding the data extraction, and the JBI ConQual method was applied for guiding the evaluation of the level of evidence for the synthesis. RESULTS: Of retrieved 2042 studies, 12 met the inclusion criteria. The total population sample included 447 participants, including 231 pregnant and postpartum women, 21 male partners, 75 healthcare providers (HCPs)/healthcare workers (HCWs), 18 policymakers, 37 mothers, and 65 women of childbearing age. A total of 149 findings with credibility ratings of "unequivocal" or "equivocal" were included in this meta-synthesis. Barriers and facilitators to preexposure prophylaxis implementation were coded into seven categories, including three facilitator categories: perceived benefits, maintaining relationships with partners, and external support, and four barriers: medication-related barriers, stigma, barriers at the level of providers and facilities, and biases in risk perception. CONCLUSION: This systematic review and meta-synthesis aggregated the barriers and facilitators of preexposure prophylaxis implementation among pregnant and postpartum women. We aggregated several barriers to maternal preexposure prophylaxis implementation, including medication-related factors, stigma, barriers at the level of providers and facilities, and risk perception biases. Therefore, intervention measures for improving preexposure prophylaxis services can be developed based on these points. PROSPERO NUMBER: CRD42023412631.

RESUMO

INTRODUCTION: Globally, transgender ('trans') women experience extreme social and economic marginalisation due to intersectional stigma, defined as the confluence of stigma that results from the intersection of social identities and positions among those who are oppressed multiple times. Among trans women, gender-based stigma intersects with social positions such as engagement in sex work and substance use, as well as race-based stigma to generate a social context of vulnerability and increased risk of HIV acquisition. In Brazil, trans women are the 'most at-risk' group for HIV, with 55 times higher estimated odds of HIV infection than the general population; further, uptake of HIV testing and pre-exposure prophylaxis (PrEP) among trans women is significantly lower than other at-risk groups. Through extensive formative work, we developed Manas por Manas, a multilevel intervention using HIV prevention strategies with demonstrated feasibility and acceptability by trans women in Brazil, to address intersectional stigma and increase engagement in the HIV prevention continuum. METHODS AND ANALYSIS: We are conducting a two-arm randomised wait-list controlled trial of the intervention's efficacy in São Paulo, Brazil, to improve uptake of HIV testing and PrEP among transgender women (N=400). The primary outcomes are changes in HIV testing (self-testing and clinic based), changes in PrEP uptake and changes in PrEP persistence at baseline and follow-up assessment for 12 months at 3-month intervals. ETHICS AND DISSEMINATION: This study was approved by University of California, San Francisco Institutional Review Board (15-17910) and Comissão Nacional de Ética em Pesquisa (Research Ethics National Commission, CAAE: 25215219.8.0000.5479) in Brazil. Participants provided informed consent before enrolment. We are committed to collaboration with National Institutes of Health officials, other researchers, and health and social services communities for rapid dissemination of data and sharing of materials. The results will be published in peer-reviewed academic journals and scientific presentations. TRIAL REGISTRATION NUMBER: NCT03081559.

RESUMO

BACKGROUND: In Kenya, 65% of sexually active unmarried women use modern contraceptives, a population at increased risk of HIV acquisition compared to other populations. Anchoring HIV prevention services, including pre-exposure prophylaxis (PrEP), to trusted contraceptive delivery settings offers opportunities to efficiently reach this important population. In Kenya, almost half (40%) of women accessing contraception services do so outside traditional healthcare facilities, such as retail pharmacies. Thus, integrating PrEP services into retail pharmacies may increase options for reaching adolescent girls and young women (AGYW) who could benefit from PrEP. Efforts are underway to define care pathways for pharmacy-delivered PrEP services in Kenya, including unsupported and supported models with nurse navigators. METHODS: The AGYW Pharmacy PrEP study is an unblinded 2-arm cluster-randomized controlled trial in Kisumu, Kenya. The objective is to determine the effect that unsupported versus supported pharmacy-delivered PrEP services has on PrEP initiation, persistence, and adherence among AGYW seeking contraception. Twenty retail pharmacies offering pharmacy provider-led PrEP delivery will be randomized 1:1 to either receive or not receive a nurse navigator to support PrEP delivery. Eligible AGYW (n = 1900 total, n = 950/arm) will be ≥ 15 years old, purchasing a method of contraception at the pharmacy. Trained pharmacy provider will offer eligible AGYW either daily oral PrEP or the monthly DPV vaginal ring. The primary trial outcomes are PrEP initiation (use of PrEP at 1 month), persistence (use of PrEP at 10 months), and adherence (quantified by levels of TFV or DPV in hair samples). Additionally, several secondary (STI incidence, PrEP method selection, predictors of PrEP adherence) and exploratory outcomes (HIV incidence, quality of care, contraceptive method mix) will be explored. DISCUSSION: We hypothesize pharmacy-delivered PrEP services supported with nurse navigator, versus delivered by pharmacy providers alone, will improve PrEP outcomes among AGYW seeking contraception. Our results will help policy makers better understand how to potentially implement this novel differentiated service model for PrEP and prime pharmacies for the delivery of new PrEP agents in the pipeline (e.g., long-acting injectables and multi-purpose technologies). The study was initiated on May 13, 2023, and is expected to be completed by February 2025. TRIAL REGISTRATION: ClinicalTrials.gov (NCT05467306), with registration on July 20, 2022.

RESUMO

BACKGROUND: Increased pre-exposure prophylaxis (PrEP) use is urgently needed to substantially decrease HIV incidence among Black sexual minority men. Low perceived risk for HIV (PRH) is a key unaddressed PrEP barrier for Black sexual minority men. Peers and smartphone apps are popular intervention tools to promote community health behaviors, but few studies have used these together in a multicomponent strategy. Therefore, we designed a multicomponent intervention called POSSIBLE that used an existing smartphone app called PrEPme (Emocha Mobile Health, Inc) and a peer change agent (PCA) to increase PRH as a gateway to PrEP. OBJECTIVE: This paper aims to describe the feasibility and preliminary impact of POSSIBLE on PRH and willingness to accept a PrEP referral among Black sexual minority men. METHODS: POSSIBLE was a theoretically guided, single-group, 2-session pilot study conducted among Black sexual minority men from Baltimore, Maryland between 2019 and 2021 (N=69). POSSIBLE integrated a PCA and the PrEPme app that allows users to self-monitor sexual risk behaviors and chat with the in-app community health worker to obtain PrEP service information. PRH was assessed using the 8-item PRH scale before and after baseline and follow-up study visits. At the end of each study visit, the PCA referred interested individuals to the community health worker to learn more about PrEP service options. RESULTS: The average age of participants was 32.5 (SD 8.1, range 19-62) years. In total, 55 (80%) participants were retained for follow-up at month 1. After baseline sessions, 29 (42%) participants were willing to be referred to PrEP services, 20 (69%) of those confirmed scheduled appointments with PrEP care teams. There were no statistically significant differences in PRH between baseline and follow-up visits (t122=-1.36; P=.17). CONCLUSIONS: We observed no statistically significant improvement in PRH between baseline and month 1. However, given the high retention rate and acceptability, POSSIBLE may be feasible to implement. Future research should test a statistically powered peer-based approach on PrEP initiation among Black sexual minority men.

RESUMO

An estimated 1.2 million people in the United States have human immunodeficiency virus (HIV) infection per US Centers for Disease Control and Prevention 2021 data. The highest risk of HIV transmission occurs during injection drug use with needle sharing and during sexual activity, most significantly in condomless, receptive anal intercourse. Preexposure prophylaxis (PrEP) for the prevention of HIV infection is part of a larger biobehavioral strategy that uses antiretroviral medication, an oral formulation taken daily or during anticipated exposure events, or an injectable formulation administered every 8 weeks. PrEP consists of 3 possible regimens: emtricitabine/tenofovir disoproxil fumarate, emtricitabine/tenofovir alafenamide, or injectable cabotegravir. Primary care clinicians are strategically positioned to provide PrEP education and access.

RESUMO

Introduction. ListerineÒ is a bactericidal mouthwash widely used to prevent oral health problems such as dental plaque and gingivitis. However, whether it promotes or undermines a healthy oral microbiome is unclear.Hypothesis/Gap Statement. We hypothesized that the daily use of Listerine Cool Mint would have a significant impact on the oropharyngeal microbiome.Aim. We aimed to assess if daily usage of Listerine Cool Mint influenced the composition of the pharyngeal microbiome.Methodology. The current microbiome substudy is part of the Preventing Resistance in Gonorrhoea trial. This was a double-blind single-centre, crossover, randomized controlled trial of antibacterial versus placebo mouthwash to reduce the incidence of gonorrhoea/chlamydia/syphilis in men who have sex with men (MSM) taking HIV pre-exposure prophylaxis (PrEP). Fifty-nine MSM taking HIV PrEP were enrolled. In this crossover trial, participants received 3 months of daily Listerine followed by 3 months of placebo mouthwash or vice versa. Oropharyngeal swabs were taken at baseline and after 3 months use of each mouthwash. DNA was extracted for shotgun metagenomic sequencing (Illumina Inc.). Non-host reads were taxonomically classified with MiniKraken and Bracken. The alpha and beta diversity indices were compared between baseline and after each mouthwash use. Differentially abundant bacterial taxa were identified using ANOVA-like differential expression analysis.Results. Streptococcus was the most abundant genus in most samples (n = 103, 61.7 %) with a median relative abundance of 31.5% (IQR 20.6-44.8), followed by Prevotella [13.5% (IQR 4.8-22.6)] and Veillonella [10.0% (IQR 4.0-16.8)]. Compared to baseline, the composition of the oral microbiome at the genus level (beta diversity) was significantly different after 3 months of Listerine (P = 0.006, pseudo-F = 2.29) or placebo (P = 0.003, pseudo-F = 2.49, permutational multivariate analysis of variance) use. Fusobacterium nucleatum and Streptococcus anginosus were significantly more abundant after Listerine use compared to baseline.Conclusion. Listerine use was associated with an increased abundance of common oral opportunistic bacteria previously reported to be enriched in periodontal diseases, oesophageal and colorectal cancer, and systemic diseases. These findings suggest that the regular use of Listerine mouthwash should be carefully considered.

RESUMO

Long-acting injectable PrEP, particularly cabotegravir (CAB-LA), has the potential to enhance HIV prevention in Asia, and was the topic of a roundtable held in Singapore in June 2023. Despite proven efficacy, CAB-LA's impact in Asia is hindered by regulatory, manufacturing, and cost barriers. There is an urgent need to address these challenges to expedite CAB-LA's introduction and scale-up, including collaborative research, streamlined regulatory processes, and increased manufacturing capacity. We call for better preparedness in long-acting PrEP in research and implementation science, product licensing and accessibility, and capacity readiness for scale-up, to meet the significant demand among key populations in Asia.

RESUMO

This article aims to discuss the expectations of Homosexual Men, Bisexual Men and a Transgender Woman, who use or want to use an oral pre-exposure prophylaxis (PrEP) for the human immunodeficiency virus (HIV) about PrEP modalities. Sixteen PrEP users, who are followed up in the BCN Checkpoint, were interviewed,. The interviews were audio-recorded, subjected to thematic categorical analysis within the theoretical framework from the praxiographic perspective. They are all adapted to the use of daily oral and event-based PrEP. In relation to the new PrEP modalities (monthly pill; intramuscular injection every two months; subcutaneous injection every six months), they are all very receptive to these possibilities, but they lack information on the specificities of each and specific assessment of their needs. Comments about the use of oral PrEP are positive, and expectations regarding the new PrEP modalities are visibly high. However, the most important thing for the interviewees is the guarantee that they will have follow-up appointments to continue taking care of their affective-sexual health, which is not dependent on the type of PrEP modalities.


Este artículo tiene como objetivo discutir las concepciones de los Hombres Gay, Hombres Bisexuales y una Mujer Transgénero que usan o quieren usar profilaxis previa a la exposición por el virus de la inmunodeficiencia humana oral (PrEP) sobre nuevas vías de administración. Fueron entrevistados 17 usuarios del BCN Checkpoint. Las entrevistas fueron grabadas en audio, sometidas a análisis categorial temático teniendo en cuenta la perspectiva praxeográfica. Todos están adaptados al uso de la PrEP diaria y a demanda. En relación con las nuevas vías de administración (PrEP inyección intramuscular cada dos meses; pastilla mensual; inyección subcutánea cada seis meses) todos son muy receptivos a esas posibilidades, pero les falta información sobre las especificidades de cada una de ellas y una evaluación específica de sus necesidades. Tanto la satisfacción con el uso de PrEP oral, como las expectativas sobre las nuevas vías de administración son positivas. Sin embargo, lo más importante para los/a entrevistados/a es la garantía de que tendrán seguimiento para continuar cuidando de la salud afectivo-sexual, lo que no depende del tipo de vía de administración.

RESUMO

BACKGROUND: Especially in high HIV prevalence contexts, such as Zambia, effective biomedical prevention tools are needed for priority populations (PPs), including key populations (KPs), who are at higher risk. HIV pre-exposure prophylaxis (PrEP) has been scaled up nationally in Zambia, but little is known about barriers to PrEP use among specific PPs to date. METHODS: To understand barriers and facilitators to PrEP use in Zambia, we conducted a qualitative case study of PrEP services to PPs including sero-discordant couples (SDCs), female sex workers (FSWs), and men who have sex with men (MSM) in Livingstone. The study conducted in 2021 included in-depth interviews (n = 43) guided by the socio-ecological model, and focus group discussions (n = 4) with clinic and community-based providers and PrEP-eligible clients including users and non-users across PP groups. We used thematic analysis to analyze data using codes derived both deductively and inductively. RESULTS: We found multilevel barriers and facilitators to PrEP use. Cross-cutting barriers shared across PP groups included amplifying effects of PrEP being mistaken for antiretroviral drugs used to treat HIV, including anticipated stigma, and concerns about side-effects based on both misinformation and experience. In addition, stigmatized identities, particularly that of MSM, served as a barrier to PrEP use. The fear of being mislabeled as having HIV was of greatest concern for FSWs. Facilitators to PrEP use primarily included the importance of confidential, KP-sensitive services, and the role of informed, supportive family, friends, and peers. Participants across all PP groups urged expanded education efforts to increase awareness of PrEP within the general population toward mitigating concerns of being mislabeled as living with HIV. CONCLUSION: To our knowledge, this is the first qualitative study of the PrEP cascade among multiple PPs in Zambia. This study provides important explanation for the low rates of PrEP continuation found in earlier demonstration trials among KPs in Zambia. The study also offers recommendations for programming efforts going forward such as inclusive PrEP awareness campaigns, expanded KP sensitivity training, and related efforts to thwart PrEP stigma while expanding access.

RESUMO

Transgender women are disproportionately impacted by HIV infection. We report herein the findings of a pre-post evaluation of the TransLife Care (TLC) project in Chicago, Illinois, on behaviors associated with HIV transmission among transgender women. Participants who received any TLC component versus those who did not were compared using mixed-effects logistic regression with random intercepts across follow-up time points. Ninety-seven participants aged 18 to 59 (median age 24) enrolled; 76.3% were transgender women of color. There was a decrease in condomless sex without consistent PrEP use at 8 months, which was not significantly different between those who did and did not receive the TLC intervention, controlling for calendar time. Evidence does not indicate that the TLC reduces condomless sex without PrEP protection among urban transgender women. However, given the preponderance of evidence of the influence of structural barriers on condomless sex, future research should continue to test the efficacy of structural interventions.

RESUMO

HIV testing is the point of entry for linkage to treatment and prevention and is critically important to ending the HIV epidemic. HIV self-testing (HST) is an acceptable, user-controlled tool that can address testing barriers, which is especially important for populations who need to test frequently, like women who exchange or trade sex for money or other needed resources (WES) and women who use drugs. HST is feasible and acceptable among WES, but research among WES who also use drugs is limited, particularly in places like Kazakhstan, where HIV rates remain high and where scale-up of HST and pre-exposure prophylaxis (PrEP) is in process. To develop effective programming, there is a need to develop tailored services for WES and/or use drugs that address key barriers. We discuss opportunities to increase HST and linkage to services among WES and/or use drugs in Kazakhstan, with a focus on stigma reduction.

RESUMO

BACKGROUND: Pre-exposure prophylaxis (PrEP) with oral emtricitabine/tenofovir disoproxil (FTC/TDF) proved highly efficient in preventing HIV. Since 09/2019, FTC/TDF-PrEP is covered by health insurances in Germany, if prescribed by licensed specialists. However, methods to longitudinally monitor progress in PrEP implementation in Germany are lacking. METHODS: Utilizing anonymous FTC/TDF prescription data from 2017-2021, we developed a mathematical model to disentangle HIV-treatment from PrEP prescriptions, as well as to translate PrEP prescriptions into number of PrEP users. We used the model to estimate past- and future PrEP uptake dynamics, to predict coverage of PrEP needs and to quantify the impact of COVID-19 on PrEP uptake on a national and regional level. RESULTS: We identified significant (p<0.01) decelerating effects of the first- and second COVID-19-lockdown on PrEP uptake in 04/2020 and 12/2020. We estimated 26,159 (CI: 25,751-26,571) PrEP users by 12/2021, corresponding to 33% PrEP coverage of people in need. We projected 64,794 (CI: 62,956-66,557) PrEP users by 12/2030, corresponding to 81% PrEP coverage. We identified profound regional differences, with high PrEP coverage and uptake in metropoles and low coverage in more rural regions. CONCLUSIONS: Our approach presents a comprehensive solution to monitor and forecast PrEP implementation from anonymous data and highlighted that the COVID-19 pandemic significantly decelerated PrEP uptake in Germany. Moreover, slow PrEP uptake in rural areas indicate that structural barriers in PrEP care, education or information exist that may hamper the goal of ending the AIDS epidemic by 2030.

RESUMO

BACKGROUND: Women who engage in sex work and use drugs (WSWUD) experience disproportionate HIV risks. Substance use treatment bridge clinics offer an opportunity to increase HIV pre-exposure prophylaxis (PrEP) delivery to WSWUD, but research on best practices is lacking. Therefore, we explored facilitators and barriers to PrEP across the PrEP care continuum in these settings. METHODS: Bridge clinic and affiliated harm reduction health service providers and WSWUD from Boston were recruited using passive and active outreach between December 2021 and August 2022. Participants were invited to take part in semi-structured phone or in-person interviews to explore HIV prevention and PrEP care experiences overall and within bridge clinic settings. Deductive codes were developed based on HIV risk environment frameworks and the Information-Motivation-Behavioral Skills model and inductive codes were added based on transcript review. Grounded content analysis was used to generate themes organized around the PrEP care continuum. RESULTS: The sample included 14 providers and 25 WSWUD. Most WSWUD were aware of PrEP and more than half had initiated PrEP at some point. However, most who initiated PrEP did not report success with daily oral adherence. Providers and WSWUD described facilitators and barriers to PrEP across the steps of the care continuum: Awareness, uptake, adherence, and retention. Facilitators for WSWUD included non-stigmatizing communication with providers, rapid wraparound substance use treatment and HIV services, having a PrEP routine, and service structures to support PrEP adherence. Barriers included low HIV risk perceptions and competing drug use and survival priorities. Provider facilitators included clinical note templates prompting HIV risk assessments and training. Barriers included discomfort discussing sex work risks, competing clinical priorities, and a lack of PrEP adherence infrastructure. CONCLUSION: WSWUD and bridge clinic providers favored integrated HIV prevention and substance use services in harm reduction and bridge clinic settings. Harm reduction and bridge clinic programs played a key role in HIV prevention and PrEP education for WSWUD. Effective behavioral and structural interventions are still needed to improve PrEP adherence for WSWUD.

RESUMO

BACKGROUND: Transgender and nonbinary populations are disproportionately affected by HIV and face barriers to accessing HIV-related services. Pre-exposure prophylaxis (PrEP) may benefit those at risk of HIV acquisition. However, PrEP awareness and uptake, along with potential barriers and facilitators, have not been investigated among transgender and nonbinary individuals living in Canada. SETTING: This study analyzed data from 1965 participants of the 2019 Trans PULSE Canada survey, a national convenience sampling survey of transgender and nonbinary individuals in Canada. METHODS: Data were analyzed to estimate levels of PrEP awareness and uptake and to identify predictors of PrEP awareness among the study population. Prevalence ratios estimated from block-wise modified Poisson regression models were used to assess predictors of PrEP awareness. RESULTS: PrEP awareness, lifetime PrEP use, and current PrEP use were estimated to be 71.0%, 2.2%, and 0.9%, respectively, among the full sample, and 82.3%, 7.3%, and 3.8% among those with indications for PrEP use. Respondents who were aged 45 years or older, transfeminine, Indigenous, living in Atlantic Canada or Quebec, and had high school education or less were significantly less likely to be aware of PrEP. Lifetime sex work, past-year HIV/STI testing, being single or in a nonmonogamous relationship, and higher levels of emotional social support were positively associated with PrEP awareness. CONCLUSIONS: There is a need to improve PrEP awareness and particularly uptake among transgender and nonbinary individuals in Canada. This study revealed inequities in PrEP awareness within this population, which may serve as targets for future public health initiatives.
