Abstract
OBJECTIVE To evaluate effectiveness of a standardized patient actor (SP) training intervention to improve quality of preexposure prophylaxis (PrEP) services for adolescent girls and young women (AGYW) in Kenya. DESIGN Cluster randomized trial and mystery shopper evaluation. METHODS Twelve of 24 maternal child health and family planning facilities were randomized to SP training. Providers at intervention facilities participated in 2-day training in adolescent health, PrEP guidelines, values clarification, and communication skills, followed by role-playing and de-briefing with trained actors. Control facilities received standard national training. The primary outcome was quality of care, assessed by unannounced SPs (USPs) or "mystery shoppers" blinded to intervention arm. Quality was measured in two domains: guideline adherence and communication skills. Intent to treat analysis compared postintervention quality scores by randomization arm, clustering on facility, and adjusting for baseline scores and USP. RESULTS Overall, 232 providers consented to USP visits, and 94 providers completed the training. Following training, USPs posed as AGYW seeking PrEP in 142 encounters (5-6 encounters per site). The mean quality score was 73.6% at intervention sites and 58.4% at control sites [adjusted mean difference = 15.3, 95% confidence interval (CI): 9.4-21.1, P < 0.001]. Mean guideline adherence scores were 57.2% at intervention sites and 36.2% at control sites (adjusted mean difference = 21.0, 95% CI: 12.5-29.4, P < 0.001). Mean communication scores were 90.0% at intervention sites and 80.5% at control sites (adjusted mean difference = 9.5, 95% CI: 5.5-13.6, P < 0.001). CONCLUSIONS SP training significantly improved quality of PrEP care for AGYW in Kenya. Incorporating SP training and unannounced SP evaluation could improve PrEP uptake among AGYW.

Abstract
Pharmaceutical drugs, including vaccines, pre- and post-exposure prophylactics, and chronic drug therapies, are crucial tools in the prevention and treatment of infectious diseases. These drugs have the ability to increase survival and improve patient quality of life; however, infectious diseases still accounted for more than 10.2 million deaths in 2019 before the COVID-19 pandemic. High mortality can be, in part, attributed to challenges in the availability of adequate drugs and vaccines, limited accessibility, poor drug bioavailability, the high cost of some treatments, and low patient adherence. A majority of these factors are logistical rather than technical challenges, providing an opportunity for existing drugs and vaccines to be improved through formulation. Injectable controlled-release drug delivery systems are one class of formulations that have the potential to overcome many of these limitations by releasing their contents in a sustained manner to reduce the need for frequent re-administration and improve clinical outcomes. This review provides an overview of injectable controlled drug delivery platforms, including microparticles, nanoparticles, and injectable gels, detailing recent developments using these systems for single-injection vaccination, long-acting prophylaxis, and sustained-release treatments for infectious disease.

Abstract
Incidence estimation of HIV infection can be performed using recent infection testing algorithm (RITA) results from a cross-sectional sample. This allows practitioners to understand population trends in the HIV epidemic without having to perform longitudinal follow-up on a cohort of individuals. The utility of the approach is limited by its precision, driven by the (low) sensitivity of the RITA at identifying recent infection. By utilizing results of previous HIV tests that individuals may have taken, we consider an enhanced RITA with increased sensitivity (and specificity). We use it to propose an enhanced estimator for incidence estimation. We prove the theoretical properties of the enhanced estimator and illustrate its numerical performance in simulation studies. We apply the estimator to data from a cluster-randomized trial to study the effect of community-level HIV interventions on HIV incidence. We demonstrate that the enhanced estimator provides a more precise estimate of HIV incidence compared to the standard estimator.

Abstract
Condoms continue to be used by many gay, bisexual, and other men who have sex with men (GBM) to reduce the risk of HIV transmission. However this is impacted by condom failure events, defined here as condom breakage and slippage. In a prospective, observational cohort study of 343 HIV serodiscordant male couples recruited through high HIV caseload clinics and hospitals between 2012 and 2016 in Australia, Brazil, and Thailand, condom failure rates and associated factors were analysed, including with the study partner versus other sexual partners. There were 717 reported instances of condom failure from an estimated total of 25,831 sex acts with condoms, from over 588.4 participant years of follow up. Of the HIV-negative partners (n = 343) in the study, more than a third (n = 117, 36.7%) reported at least one instance of condom failure with any partner type during study follow-up. Condom failure with their study partner was reported by 91/343 (26.5%) HIV-negative partners, compared with 43/343 (12.5%) who reported condom failure with other partners. In total, there were 86 events where the HIV-negative partner experienced ano-receptive condom failure with ejaculation, representing 12.0% of all failure events. In multivariable analysis, compared to Australia, HIV-negative men in Brazil reported a higher incidence risk rate of condom failure (IRR = 1.64, 95%CI 1.01-2.68, p = 0.046) and HIV-negative men who reported anal sex with other partners reported an increased risk of condom failure compared with men who only had sex with their study partner (IRR = 1.89, 95%CI 1.08-3.33, p = 0.025). Although at least one event of condom failure was reported by a significant proportion of participants, overall condom failure events represented a small proportion of the total condom protected sex acts.

Abstract
Sexual minority men (SMM) are disproportionately affected by HIV. Although pre-exposure prophylaxis (PrEP) is an effective way of reducing HIV incidence, PrEP use has remained relatively low. Social support may be one effective factor in increasing PrEP use among SMM, but the association between social support and PrEP use/adherence is not well understood. The objective of this paper was to summarize the current literature on the association of social support and PrEP use among SMM in the United States. A systematic search was conducted using six different databases MEDLINE / PubMed, PsycINFO, Cochrane CENTRAL, Google Scholar, Embase, and Web of Science using terms established from keywords and medical subject headings (MeSH) terms before being adapted to each database. Data were extracted for key study factors (e.g., study population, geographic location, study design) and main findings. This search produced eleven articles: ten manuscripts and one conference abstract. Of these, two were randomized control trials, two were interventions, three were qualitative, and four were cross-sectional. The studies were widespread across the country, but most were in major metropolitan areas. From the articles included in this review, findings were inconsistent in the association between social support; some studies showed null findings, others that only certain sources of social support were significant, and others that there was a significant association between social support and PrEP use. This review highlights the complexity of the relationship between social support and PrEP use among SMM, indicating the need for further research to identify specific types and sources of support that effectively enhance PrEP uptake and adherence. Targeted interventions based on these insights could significantly reduce HIV incidence in the population.

Abstract
BACKGROUND Latino, Latina, and Latinx (Latino/a/x) individuals remain disproportionately impacted by HIV, particularly sexual minority men and transgender women. Pre-exposure prophylaxis (PrEP) is an effective means of biomedical HIV prevention, but awareness and uptake remain low among marginalized Latino/a/x populations. Social marketing campaigns have demonstrated promise in promoting PrEP in other populations but are poorly studied in Latino/a/x sexual minority men and transgender women. OBJECTIVE This study aims to (1) adapt and pilot a PrEP social marketing campaign tailored to Latino/a/x populations with a focus on sexual minority men and transgender women through community-based participatory research (CBPR) and (2) evaluate the reach and ad performance of the adapted PrEP social marketing campaign. METHODS We used the ADAPT-ITT (assessment, decision, adaptation, production, topical experts-integration, training, and testing) framework for adapting evidence-based interventions for new settings or populations. This paper presents how each phase of the ADAPT-ITT framework was applied via CBPR to create the PrEPárate ("Be PrEPared") campaign. Key community engagement strategies included shared ownership with community partners, focus groups to guide content, crowdsourcing to name the campaign, design by local Latino/a/x artists, and featuring local influencers as the faces of PrEPárate. We evaluated campaign reach and advertisement performance using social media platform metrics (paid and organic reach, impressions, unique clicks, and click-through rates [CTR]) and website use statistics from Google Analytics. RESULTS The PrEPárate campaign ran in Cook County, Illinois, from April to September 2022. The campaign reached over 118,750 people on social media (55,750 on Facebook and Instagram [Meta Platforms Inc] and 63,000 on TikTok [ByteDance Ltd]). The Meta ads performed over the industry benchmark with ads featuring local transgender women (2% CTR) and cisgender sexual minority men (1.4% CTR). Of the different Grindr (Grindr Inc) ad formats piloted, the interstitial Grindr ads were the highest performing (1183/55,479, 2.13% CTR). YouTube (Google) ads were low performing at 0.11% (153/138,337) CTR and were stopped prematurely, given limits on sexual education-related content. In the first year, there were 5006 visitors to the website. CONCLUSIONS Adaptation of an existing evidence-based intervention served as an effective method for developing a PrEP social marketing campaign for Latino/a/x audiences. CBPR and strong community partnerships were essential to tailor materials and provide avenues to systematically address barriers to PrEP access. Social marketing is a promising strategy to promote PrEP among underserved Latino/a/x populations.

Abstract
BACKGROUND HIV preexposure prophylaxis (PrEP) has proven to be efficacious and effective in preventing HIV infections, but few studies have reported its impact in the real world. METHODS We conducted an ecological analysis and compared the trends in HIV PrEP prescriptions with the trends in age-adjusted HIV diagnosis rates in New York City (NYC). Joinpoint regression analyses were used to identify any temporal trends in HIV diagnosis rates in NYC. RESULTS The number of people filling at least one PrEP prescription in NYC increased from 2551 in 2014 to 35 742 in 2022. The overall age-adjusted HIV diagnosis rate steadily decreased from 48.1 per 100 000 in 2003 to 17.1 per 100 000 in 2022. After the rollout of PrEP, accelerated decreases were detected in some subpopulations including white men [2014-2019 annual percentage change (APC): -16.6%; 95% confidence interval (CI) -22.7 to -10.0], Asian/Pacific Islander men (2016-2022 APC: -9.8%), men aged 20-29 years (2017-2020 APC: -9.4%) and 40 -49 years (2014-2020 APC: -12.2%), Latino/Hispanic people aged 40-49 years (2015-2020 APC: -13.0%), white people aged 20-29 years (2012-2022 APC: -11.4%) and 40-49 years (2014-2018 APC: -27.8%), and Asian/Pacific Islander people aged 20-29 years (2017-2022 APC: -13.0%). CONCLUSION With a high coverage, PrEP can have a long-term impact in reducing HIV infections in a population, but if preexisting social determinants that contribute to racial, ethnic, and gender inequities are not well addressed, the implementation of PrEP can exacerbate these inequalities.

Abstract
Uptake of pre-exposure prophylaxis medication (PrEP) to prevent HIV among people who inject drugs (PWID) remains extremely low in the United States. West Virginia's rising HIV incidence and highest drug overdose rate in the nation makes it an important locus for opioid use and HIV risk interaction. In this pilot study we pioneered the use of Cultural Theory among PWID to understand HIV-related risk perception arising from four contrasting modes of social organization. Carried out during an HIV outbreak, we explored PrEP uptake qualitatively as a window onto risk perception. Of the 26 interviewees, 18 were HIV- and despite the medication's free availability from the health center where recruitment took place, none had taken PrEP, half considering they were not at risk. Intimate couples who showed characteristics of 'enclaves' considered the boundary around themselves protective against HIV, creating a safe space or 'invisible risk group'. Higher HIV risk was perceived among those who were housed compared to those living homeless. Beliefs about the causation of the local HIV outbreak and the validity of scientific research corresponded with characteristics of the contrasting modes of social organization and the approach is promising for informing public health interventions among PWID.

Lancet HIV 2024:S2352-3018(24)00130-9. [PMID: 39008999 DOI: 10.1016/s2352-3018(24)00130-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Revised: 05/14/2024] [Accepted: 05/16/2024] [Indexed: 07/17/2024]
Abstract
BACKGROUND Data characterising the long-term use and safety of emtricitabine plus tenofovir disoproxil fumarate as daily oral pre-exposure prophylaxis (PrEP) are scarce and there are uncertainties regarding the value of routine HIV-1 RNA testing during oral PrEP follow-up. METHODS The DISCOVER trial was a randomised, controlled, phase 3 trial in which cisgender men and transgender women aged 18 years and older with a high likelihood of acquiring HIV were recruited from 94 clinics in Europe and North America and randomly assigned to receive either emtricitabine plus tenofovir disoproxil fumarate (200/25 mg) tablets daily, with matched placebo tablets, or emtricitabine plus tenofovir alafenamide (200/300 mg) tablets daily, with matched placebo tablets, for at least 96 weeks. After completion of the trial, participants were offered enrolment in this 48-week open-label extension study of emtricitabine plus tenofovir alafenamide. In participants diagnosed with HIV during the randomised and open-label phases of the study, we characterised HIV-1 test results and measured HIV-1 RNA viral load retrospectively when available. Adherence based on tenofovir diphosphate concentrations in dried blood spots and genotypic resistance were assessed in participants diagnosed with HIV. Safety assessments included adverse events, laboratory parameters, and, in a subset of participants, bone mineral density. HIV-1 incidence in participants initially randomly assigned to receive emtricitabine plus tenofovir alafenamide was estimated using a Poisson distribution. Changes from baseline in safety endpoints were described in participants assigned to received emtricitabine plus tenofovir alafenamide and in those who switched from emtricitabine plus tenofovir disoproxil fumarate during the open-label phase. This trial is registered with ClinicalTrials.gov, NCT02842086, and is ongoing. FINDINGS Between Sept 13, 2016, and June 30, 2017, 5399 participants were enrolled and randomly assigned in DISCOVER. 2699 were assigned to receive emtricitabine plus tenofovir disoproxil fumarate and 2700 were assigned to receive emtricitabine plus tenofovir alafenamide, of whom 2693 and 2694, respectively, received at least one dose of study drug. 2115 (79%) assigned to emtricitabine plus tenofovir disoproxil fumarate switched to emtricitabine plus tenofovir alafenamide in the open-label phase, and 2070 (77%) continued with emtricitabine plus tenofovir alafenamide in the open-label phase. As of data cutoff (Dec 10, 2020), after 15 817 person-years of follow-up, 27 new HIV-1 diagnoses were observed across the total study period, with three occurring during the open-label phase. In participants who were initially assigned to emtricitabine plus tenofovir alafenamide, the incidence was 0·13 per 100 person-years (95% CI 0·061-0·23; ten of 2670). Stored plasma samples were available for 23 of 27 participants, including 22 with incident infection. In four (17%) of 23 participants, retrospective testing detected HIV-1 RNA before serological HIV-1 test positivity; one was a suspected baseline infection. Of the three incident cases, all three were non-adherent to PrEP and none developed drug resistance. Among participants taking emtricitabine plus tenofovir alafenamide for up to 144 weeks, markers of glomerular filtration and proximal renal tubule dysfunction (β2-microglobulin to creatinine ratio and retinol-binding protein to creatinine ratio) improved or remained stable at 144 weeks compared with baseline, bone mineral density in hip and lumbar spine increased or remained stable from baseline to week 144 (n=191), cholesterol and glucose concentrations remained stable, and median bodyweight increased by less than 1 kg per year. In participants who switched from emtricitabine plus tenofovir disoproxil fumarate during the open-label phase (2115 [79%] of 2693), markers of glomerular filtration and proximal renal tubule dysfunction improved or remained stable, bone mineral density increased, cholesterol concentrations increased, glucose concentrations were similar, and median bodyweight increased more compared with those who remained on emtricitabine and tenofovir alafenamide. INTERPRETATION Routine HIV-1 RNA testing for follow-up of individuals on daily oral PrEP provides modest additional clinical benefit. Long-term use of emtricitabine and tenofovir alafenamide as daily oral PrEP is safe and well tolerated and can be an especially appropriate choice for people with bone or renal morbidities.

Abstract
Men who have sex with men (MSM) are vulnerable to HIV infection. Although daily oral pre-exposure prophylaxis (PrEP) prevents HIV among MSM, its usage remains low. We conducted virtual in-depth interviews (IDIs) and focus groups (FGs) with Black, Hispanic/Latino, and White MSM consisting of current PrEP users and those aware of but not currently using PrEP. We delved into their preferences regarding six emerging PrEP products: a weekly oral pill, event-driven oral pills, anal douche/enema, anal suppository, long-acting injection, and a skin implant. Our mixed methods analysis involved inductive content analysis of transcripts for thematic identification and calculations of preferences. Among the sample (n = 98), the weekly oral pill emerged as the favored option among both PrEP Users and PrEP Aware IDI participants. Ranking exercises during FGs also corroborated this preference, with the weekly oral pill being most preferred. However, PrEP Users in FGs leaned toward the long-acting injectable. Conversely, the anal suppository and douche/enema were the least preferred products. Overall, participants were open to emerging PrEP products and valued flexibility but expressed concerns about limited protection for products designed solely for receptive sex. Public health practitioners should tailor recommendations based on individuals' current sexual behaviors and long-term vulnerability to infection.

Abstract
Sexual minority young men experience a high HIV incidence. Parent-based interventions are promising for prevention efforts, but further research is needed to identify specific, replicable parental behaviors associated with improved sexual health outcomes for sexual minority young men. We assessed parental behaviors in the domains of facilitating access to condoms, providing instruction in condom use, and supporting HIV testing, and tested whether parental behaviors were associated with sons' condom use self-efficacy and intentions to get tested for HIV. Data came from the baseline assessment of a pilot trial of a parent-based HIV prevention program, and participants were dyads (n = 61) of sexual minority young men (M. age: 16.87; 46% racial/ethnic minority) and their parents (M. age: 44.31; 26% racial/ethnic minority). Parents and sons reported on parental behaviors in each domain. Results indicated that parents' facilitation of access to condoms was associated with sons' condom use self-efficacy, and parents' facilitation of HIV testing was associated with sons' HIV testing intentions. Findings were robust across both parent and son reports of parental behaviors. Parental condom use instruction was unrelated to sons' condom use self-efficacy. Findings suggest that parent-based HIV prevention programs for sexual minority young men should encourage parents to provide instrumental assistance to their sons in accessing condoms and HIV testing. There is a need for further research to identify underlying mechanisms.

Correlates of oral pre-exposure prophylaxis cessation among men who have sex with men in China: implications from a nationally quantitative and qualitative study. BMC Public Health 2024; 24:1765. [PMID: 38956521 PMCID: PMC11221119 DOI: 10.1186/s12889-024-19182-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2023] [Accepted: 06/18/2024] [Indexed: 07/04/2024] Open
Abstract
BACKGROUND Several studies have demonstrated the population-level effectiveness of oral PrEP in reducing the risk of HIV infection. However, oral PrEP utilization among MSM in China remains below 1%. While existing literature has primarily focused on oral PrEP preference and willingness, there is limited exploration of the underlying factors contributing to oral PrEP cessation in China. This study aims to fill this gap by investigating the factors associated with oral PrEP cessation among MSM in China. METHODS Assisted by MSM community organizations, we collected 6,535 electronic questionnaires from 31 regions across China, excluding Taiwan, Hong Kong, and Macau. The questionnaire focused on investigating MSM's awareness, willingness, usage, and cessation of oral PrEP. Additionally, 40 participants were randomly chosen for key informant interviews. These qualitative interviews aimed to explore the reasons influencing MSM discontinuing oral PrEP. RESULTS We eventually enrolled 6535 participants. Among the 685 participants who had used oral PrEP, 19.70% (135/685) ceased oral PrEP. The results indicated that individuals spending > ¥1000 on a bottle of PrEP (aOR = 2.999, 95% CI: 1.886-4.771) were more likely to cease oral PrEP compared to those spending ≤ ¥1000. Conversely, individuals opting for on-demand PrEP (aOR = 0.307, 95% CI: 0.194-0.485) and those using both daily and on-demand PrEP (aOR = 0.114, 95% CI: 0.058-0.226) were less likely to cease PrEP compared to those using daily PrEP. The qualitative analysis uncovered eight themes influencing oral PrEP cessation: (i) High cost and low adherence; (ii) Sexual inactivity; (iii) Lack of knowledge about PrEP; (iv) Trust in current prevention strategies; (v) Poor quality of medical service and counseling; (vi) PrEP stigma; (vii) Partner and relationship factors; (viii) Access challenges. CONCLUSIONS The cessation of oral PrEP among MSM in China is associated with various factors, including the cost of oral PrEP medication, regimens, individual perception of HIV risk, stigma, and the quality of medical services. It is recommended to provide appropriate regimens for eligible MSM and develop tailored combinations of strategies to enhance PrEP awareness and acceptance among individuals, medical staff, and the MSM community. The findings from this study can support the refinement of HIV interventions among MSM in China, contributing to efforts to reduce the burden of HIV in this population.

Abstract
Background HIV Vaccine Trials Network (HVTN) 704/085, a placebo-controlled clinical trial assessing the efficacy of VRC01 broadly neutralizing antibody infusion for HIV prevention, offered oral preexposure prophylaxis (PrEP) as the standard of prevention at no cost to participants. Methods We characterized features of- identified factors associated with- PrEP initiation and discontinuation, and the effects of PrEP initiation on HIV incidence. Results Of 2221 participants, 31.8% initiated oral PrEP during study follow-up, with the highest proportion of PrEP initiations in Brazil (83.2%) and the United States (US) (54.2%). Prior PrEP use was associated with PrEP initiation (hazard ratio [HR], 2.22 [95% confidence interval {CI}, 1.25-3.95]). Participants from Switzerland (HR, 0.5 [95% CI, .3-1.0]) and Peru (HR, 0.08 [95% CI, .06-.1]) had lower likelihood of PrEP initiation compared to the US, while participants from Brazil had higher likelihood (HR, 2.6 [95% CI, 2.0-3.3]). In the US, PrEP initiation was lower in areas with higher unmet need for PrEP (HR, 0.9 per 5 units [95% CI, 0.8-1.0]). PrEP initiators had 58% less risk of acquiring HIV than PrEP noninitiators. Among PrEP initiators, 34.4% discontinued PrEP during study follow-up. Brazil had 63% less likelihood of PrEP discontinuation than the US (HR, 0.37 [95% CI, .22-.60]). Conclusions When included as standard of prevention in HVTN 704/085, oral PrEP utilization patterns mirrored those observed in real-life settings. Variable effects of oral PrEP on HIV outcomes in clinical trials may be expected based on regional differences in oral PrEP use.

Abstract
Background Simplified hepatitis C virus (HCV) testing integrated into existing HIV services has the potential to improve HCV diagnoses and treatment. We evaluated the cost-effectiveness of integrating different simplified HCV testing strategies into existing HIV pre-exposure prophylaxis (PrEP) and treatment services among men who have sex with men (MSM) in Taiwan. Methods Mathematical modeling was used to assess the cost-effectiveness of integrating simplified HCV tests (point-of-care antibody, reflex RNA, or immediate point-of-care RNA) with HCV treatment into existing HIV prevention and care for MSM from a healthcare perspective. The impact of increasing PrEP and HIV treatment coverage among MSM in combination with these HCV testing strategies was also considered. We reported lifetime costs (2022 US dollars) and quality-adjusted life years (QALYs) and calculated incremental cost-effectiveness ratios (ICERs) with a 3% annual discounting rate. Findings Point-of-care HCV antibody and reflex RNA testing are cost-effective compared to current HCV testing in all PrEP and HIV treatment coverage scenarios (ICERs <$32,811/QALY gained). Immediate point-of-care RNA testing would be only cost-effective compared to the current HCV testing if coverage of HIV services remained unchanged. Point-of-care antibody testing in an unchanged HIV services coverage scenario and all simplified HCV testing strategies in scenarios that increased both HIV PrEP and treatment coverage form an efficient frontier, indicating best value for money strategies. Interpretation Our findings support the integration of simplified HCV testing and people-centered services for MSM and highlight the economic benefits of integrating simplified HCV testing into existing services for MSM alongside HIV PrEP and treatment. Funding This study was made possible as part of a research-funded PhD being undertaken by HJW under the UNSW Sydney Scientia scholarship and was associated with the Rapid Point of Care Research Consortium for infectious disease in the Asia Pacific (RAPID), which is funded by an NHMRC Centre for Research Excellence.

Abstract
INTRODUCTION We used a Programme Science platform, to generate evidence to support the implementation of programmes for sex workers in Africa. Female sex workers are estimated to make up 1.6% (1.3%-1.8%) of the population of women aged 15-49 years in Zimbabwe. We highlight how programme science can be used to help distinguish between when, where and with whom programmes need to be implemented and discuss two case studies that exemplify implementing better (Case study 1 (1 June 2019-30 June 2021) Optimizing implementation of a risk differentiated microplanning intervention) and implementing differently (Case study 2 (1 October 2016-30 September 2022) Reorientating implementation of DREAMS for young women selling sex). METHODS Zimbabwe's nationally scaled programme for sex workers was established in 2009 in partnership with sex workers to provide comprehensive services for sex workers and generate evidence for programme design, implementation and scale up. Since inception, comprehensive data have been collected from all sex workers seeking services. As the scope of service provision has expanded so has the scope of data collection and analysis. At enrolment, sex workers are assigned an alphanumeric unique identifier which links consultations within and across programme sites. We conduct descriptive analyses of the Key Population (KP) programme data to guide programme implementation and redesign, embedding programmatic qualitative enquiry as required. RESULTS Two case studies describing different approaches to programme optimization are presented. In the first, an optimization exercise was used to strengthen programme implementation ensuring that the KP programme got back on track after SARS-COV-2. In the second, an in-depth review of research and programme data led to a re-orientation of the DREAMS programme to ensure that young women at the highest risk of HIV acquisition were enrolled and had access to DREAMS social support interventions in turn strengthening their uptake of HIV prevention. CONCLUSIONS Optimizing and sustaining HIV care and treatment programmes requires effective delivery with sufficient scale and intensity for population impact. Our programme science approach guided the scale up of the KP programme in Zimbabwe, providing evidence to support strategy, implementation and ongoing management, and importantly helping us distinguish between when we needed to just implement, implement better or implement differently.

Longitudinal evolution of the HIV effective reproduction number following sequential expansion of treatment as prevention and pre-exposure prophylaxis in British Columbia, Canada: a population-level programme evaluation. Lancet HIV 2024; 11:e461-e469.

Abstract
BACKGROUND Treatment as prevention and pre-exposure prophylaxis (PrEP) are key strategies in the control of HIV/AIDS. We aimed to characterise the longitudinal effects of antiretroviral therapy (ART), followed by treatment as prevention and the addition of PrEP, on the HIV effective reproduction number (Re) in British Columbia, Canada. METHODS This population-level programme evaluation used data from the Drug Treatment Program of the British Columbia Centre for Excellence in HIV/AIDS (Vancouver, British Columbia, Canada). We also used estimates of HIV incidence and prevalence from the Public Health Agency of Canada, data on the number of new HIV diagnoses per year from the British Columbia Centre for Disease Control, and mortality data from the British Columbia Vital Statistics Agency. Data were obtained from 1985 until 2022, depending on the database source. Outcomes were the annual HIV prevalence, HIV incidence, number of new HIV diagnoses, number of people living with HIV on ART, HIV/AIDS-related and all-cause mortality rates, the HIV incidence-to-all-cause-mortality ratio, and Re. We calculated the modified effective reproduction number (Rme) using two thresholds of viral suppression and compared these values with Re. FINDINGS We found a 95% decline in HIV/AIDS-related mortality and a 91% decrease in HIV incidence over the study period. The Re progressively declined from 1996 to 2022; however, from 1996 to 2017, Rme remained stable (>1) when calculated for people living with HIV with unsuppressed viraemia, suggesting that treatment as prevention reduces HIV incidence by decreasing the pool of individuals who are potentially able to transmit the virus. From 2018 to 2022, a decline in the estimated Re and Rme (<1) was observed regardless of whether we considered all people living with HIV or only those who were virologically unsuppressed. This finding suggests that PrEP decreases HIV incidence by reducing the number of susceptible individuals in the community, independently of viral suppression. INTERPRETATION Our results show the synergy between generalised treatment as prevention and targeted PrEP in terms of decreasing HIV incidence. These findings support the incorporation of longitudinal monitoring of Re at a programmatic level to identify opportunities for the optimisation of treatment-as-prevention and PrEP programmes.

Abstract
OBJECTIVE We assessed the association and concordance between self-reported oral pre-exposure prophylaxis (PrEP) intake in a diary app and intraerythrocytic drug metabolite concentrations. DESIGN AMPrEP was a prospective demonstration study providing daily and event-driven PrEP to MSM in Amsterdam, the Netherlands (2015-2020). METHODS Participants could record their PrEP intake in a diary app. Dried blood spots (DBS) were taken at 6, 12, 24, and 48 months and analysed for tenofovir diphosphate (TFV-DP) and emtricitabine triphosphate (FTC-TP) concentrations. We included TFV-DP measurements preceded by diary completion on at least 90% of days in the 6 weeks prior. We examined the association between self-reported PrEP intake (i.e. number of pills) and TFV-DP concentrations using tobit regression with a random intercept per participant. We also calculated concordance between categorized PrEP intake (i.e. <2, 2-3, 4-6 or 7 pills per week) and categorized TFV-DP concentrations (i.e. <350, 350-699,700-1249 or ≥1250 fmol/punch) using weighted Cohen's kappa. Last, we calculated concordance between self-reported recent PrEP intake (yes/no, in past 2 days) and quantifiability of FTC-TP (yes/no) using Cohen's kappa. RESULTS Seven hundred and fifty-nine DBS measurements from 282 MSM were included. Self-reported PrEP intake was strongly and positively associated with TFV-DP concentration ( β = 0.77, 95% CI = 0.70-0.84, P < 0.0001). Concordance between categorized PrEP intake and TFV-DP concentration was moderate ( κ = 0.44, 95% CI = 0.39-0.50). Concordance between self-reported recent PrEP intake and FTC-TP quantifiability was perfect ( κ = 0.83, 95% CI 0.76-0.90). CONCLUSION Self-reported PrEP intake in a diary app is strongly correlated with actual use, and therefore reliable for comparing PrEP adherence between groups. Still, suboptimal criterion validity according to clinically relevant categories warrants caution when assessing 6-week reported adherence for individuals.

Abstract
This scoping review aimed to review and summarize the evidence related to the attitudes toward human immunodeficiency virus (HIV) pre-exposure prophylaxis (PrEP)/postexposure prophylaxis (PEP) among people at risk of HIV, health care workers (HCWs), and the general population in India. A literature search of PubMed, Embase, Scopus, and PsycINFO was conducted from January 1, 2002, to February 1, 2024. The search field contained a combination of keywords and MeSH terms such as: HIV, PrEP, PEP knowledge, awareness, willingness, and practice. Studies published in English language, conducted in India, and having reported at least one prespecified outcome related to PrEP or PEP were included. Of 599 studies identified, 48 were included (PrEP, n = 17 studies; PEP, n = 31 studies). Among the people at risk of HIV, awareness about PrEP was very low (17% or less). However, willingness to use PrEP and interest in knowing more or obtaining PrEP were reported to be high (84-95%). Among the health care professionals, the knowledge and awareness of PEP and its dosing schedule varied from 20% to 96%. The uptake to prevent this occupational hazard was reported to be poor (12-36%). This scoping review highlighted critical research gaps related to PrEP and PEP in India, related to PrEP adherence, outcomes related to nonoccupational PEP, HCW readiness to provide PrEP, etc. Overall, this study indicated the need to design policies and implement interventions aimed toward improving the knowledge, awareness, and uptake of PrEP/PEP in India. An increased focus on improving PrEP/PEP access in India through government schemes at a lower cost is imperative.

Willingness to Use Long-Acting Injectable Cabotegravir and Associated Factors Among Men Who Have Sex with Men in Guangxi, China. ARCHIVES OF SEXUAL BEHAVIOR 2024; 53:2795-2806. [PMID: 38849704 DOI: 10.1007/s10508-024-02886-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Revised: 04/10/2024] [Accepted: 04/30/2024] [Indexed: 06/09/2024]
Abstract
Cabotegravir (CAB-LA), the first long-acting injectable pre-exposure prophylaxis (PrEP), has been approved for use in the USA and is not currently on the market in China. However, willingness to use CAB-LA and associated factors among men who have sex with men (MSM) have not yet been evaluated in China. A cross-sectional study was conducted in Guangxi, China, in 2022 recruiting 1,006 MSM. Their mean age was 30.2 years, 74.2% had college or above education, and 48.6% had a monthly income between 3,000 and 5,999 Chinese yuan (CNY). Most (73.4%) had previously heard of PrEP while few (8.3%) had ever used this type of preventative medication. Willingness to use CAB-LA was 79.8% and was positively associated with eight variables: younger age, being married to a woman, having a low monthly income, having six or more male partners in the past six months, having only regular male partners in the past month, having a high perceived risk of HIV infection, and history of using PrEP. Ten other variables were not significantly associated with willingness to use CAB-LA. Among 894 participants who were willing to use or did not definitely reject using CAB-LA, the main concerns about CAB-LA were its side effects (90.2%), efficacy (63.6%), and high cost (58.2%). Only 14.7% were willing to pay more than 1,200 CNY (~US$180) every two months to use CAB-LA. The preferred injection places were centers for disease control facilities, hospitals, and social organizations. Many (89.0%) said that they would recommend CAB-LA to their male sexual partners. We conclude that willingness to use CAB-LA was high among MSM in Guangxi. However, implementation of CAB-LA faces tough challenges due to its high cost and the low use of PrEP. Peer education may play a large role in the implementation of CAB-LA in China.

Abstract
Pre-exposure prophylaxis (PrEP) use may be associated with risk compensation. We enrolled and provided PreP to sexual and gender minorities (SGM) in Abuja, Nigeria between April 2018 and May 2019. Behavioral information and samples for urogenital and anorectal Chlamydia trachomatis and Neisseria gonorrhoeae sexually transmitted infections (STIs) were collected at baseline. Blood samples for PrEP assay and self-reported adherence were collected at three-monthly follow-up visits. STIs were detected using Aptima Combo2 assay. We estimated the odds ratios (ORs) of PCR-diagnosed bacterial STIs and self-reported behavioral outcomes (condomless anal intercourse [CAI] and concurrent sexual relationships) with conditional logistic regression. Of 400 SGM who initiated PrEP, 206 were eligible for analysis, and had a median age of 24 years (IQR 22-27). In multivariable analysis, participants in the PrEP period had decreased odds of CAI (adjusted OR: 0.49, 95% CI 0.28, 0.84). PrEP use was not associated with risk compensation.

Abstract
OBJECTIVES HIV pre-exposure prophylaxis (PrEP) is effective in preventing HIV, but some seroconversions occur due to poor adherence or PrEP discontinuation. Our objective was to estimate the incidence of PrEP discontinuation and describe the reasons and factors associated with discontinuations. METHODS A retrospective cohort was conducted in three French hospitals between January 2016 and June 2022. PrEP users who attended at least twice within 6 months during study period were included and followed up until December 2022. The incidence rate of PrEP discontinuation was estimated by censoring lost to follow up individuals. Factors associated with PrEP discontinuations were identified using a multivariate Cox model. RESULTS A total of 2785 PrEP users were included, with 94% men and 5% transgender people. Median age was 35 years. By December 2022, 653 users had stopped PrEP (24%). The incidence rate was 10.8 PrEP discontinuations for 100 person-years (PY). The main causes of discontinuation were being in a stable relationship (32%), and not judging the treatment useful anymore (12%). Individuals who discontinued PrEP were younger [<29, HR = 1.45 (1.17-1.80)], and more likely to be women [HR = 2.44 (1.50-3.96)] or sex workers [HR = 1.53 (0.96-2.44)]. They were more likely to report PrEP side effects [HR = 2.25 (1.83-2.77)] or ≥2 sexually transmitted infections [HR = 1.87 (1.53-2.27)] during the last year. CONCLUSION The incidence of PrEP discontinuations was quite low compared to rates observed in other cohorts. Users who stopped PrEP were sometimes still exposed to HIV, emphasizing the need for targeted interventions to prepare and support PrEP discontinuations and limit seroconversion risk.

Abstract
INTRODUCTION Adolescent girls and young women (AGYW) who may benefit from HIV pre-exposure prophylaxis (PrEP) face high levels of common mental disorders (e.g. depression, anxiety). Common mental disorders can reduce PrEP adherence and increase HIV risk, yet mental health interventions have not been well-integrated into PrEP delivery. METHODS We conducted a four-phase human-centred design process, from December 2020 to April 2022, to understand mental health challenges among AGYW in Johannesburg, South Africa and barriers to integrated mental health and PrEP services. In the "Discover" phase, we conducted in-depth interviews with AGYW and key informants (KIs) in Johannesburg. We conducted a rapid qualitative analysis, informed by the Consolidated Framework for Implementation Research (CFIR), to identify facilitators and barriers of integrated mental health and PrEP services and mapped barriers to potential implementation strategies. In the "Design" and "Build" phases, we conducted stakeholder workshops to iteratively adapt an evidence-based mental health intervention, the Friendship Bench, and refine implementation strategies for South African PrEP delivery settings. In the "Test" phase, we piloted our adapted Friendship Bench package. RESULTS Interviews with 70 Discover phase participants (48 AGYW, 22 KIs) revealed the importance of integrated mental health and PrEP services for South African AGYW. Interviewees described barriers and implementation strategies for mental health and PrEP services around the CFIR domains: intervention characteristics (e.g. challenges with AGYW "opening up"); outer Johannesburg setting (e.g. community stigma); inner clinic setting (e.g. judgemental healthcare providers); characteristics of counsellors (e.g. training gaps); and the implementation process (e.g. need for demand creation). The Design and Build workshops included 13 AGYW and 15 KIs. Implementation barriers related to the quality and accessibility of public-sector clinic services, lay counsellor training, and community education and demand creation activities were prioritized. This led to 12 key Friendship Bench adaptations and the specification of 10 implementation strategies that were acceptable and feasible in initial pilot testing with three AGYW. CONCLUSIONS Using a human-centred approach, we identified determinants and potential solutions for integrating mental health interventions within PrEP services for South African AGYW. This design process centred stakeholders' perspectives, enabling rapid development of an adapted Friendship Bench intervention implementation package.

Abstract
INTRODUCTION People with HIV are living longer due to advances in antiretroviral therapy. With improved life expectancy comes an increased lifetime risk of comorbid conditions - such as cardiovascular disease and cancer - and polypharmacy. Older adults, particularly those living with HIV, are more vulnerable to drug interactions and adverse effects, resulting in negative health outcomes. AREA COVERED Antiretrovirals are involved in many potential drug interactions with medications used to treat common comorbidities and geriatric conditions in an aging population of people with HIV. We review the mechanisms and management of significant drug-drug interactions involving antiretroviral medications and non-antiretroviral medications commonly used among older people living with HIV. The management of these interactions may require dose adjustments, medication switches to alternatives, enhanced monitoring, and considerations of patient- and disease-specific factors. EXPERT OPINION Clinicians managing comorbid conditions among older people with HIV must be particularly vigilant to side effect profiles, drug-drug interactions, pill burden, and cost when optimizing treatment. To support healthier aging among people living with HIV, there is a growing need for antiretroviral stewardship, multidisciplinary care models, and advances that promote insight into the correlations between an individual, their conditions, and their medications.

Abstract
Cisgender women and transgender men are less likely to be assessed for PrEP eligibility, prescribed PrEP, or retained in PrEP care. Thus, this pilot PrEP educational intervention was tailored for healthcare providers (HCPs) in obstetrics/gynecology who provide care to cisgender women and transgender men in an academically-affiliated, public hospital women's health clinic. The three-lecture educational curriculum designed for HCPs focused on PrEP eligibility and counseling, formulations and adherence, and prescription and payment assistance programs. Pre- and post-intervention surveys assessed HCP knowledge and barriers to PrEP counseling and prescription. Among n = 49 participants (mean age = 32.8 years; 85.7% cisgender women, mean years practicing = 4.2 years) pre-intervention, 8.7% had prior PrEP training and 61.2% felt very/somewhat uncomfortable prescribing PrEP. Post-intervention, knowledge of PrEP contraindications, eligibility, follow-up care, and assistance programs all increased. HCPs identified key barriers to PrEP care including lack of a dedicated PrEP navigator, culturally and linguistically appropriate patient materials on PrEP resources/costs, and PrEP-related content integrated into EHRs. Ongoing PrEP educational sessions can provide opportunities to practice PrEP counseling, including information on financial assistance. At the institutional level, incorporating PrEP screening in routine clinical practice via EMR prompts, facilitating PrEP medication monitoring, and enhancing telehealth for follow-up care could enhance PrEP prescription.

Abstract
Pre-exposure prophylaxis (PrEP), including daily oral, on-demand, and long-acting injectable (LAI), is a promising HIV prevention intervention for men who have sex with men (MSM). We conducted a systematic review on engagement with the PrEP continuum among MSM in China. A total of 756 studies were initially identified and 36 studies were included (N = 26,021). In the 20 studies (N = 13,886) examining PrEP awareness, 32.4% (95% CI: 25.1-40.7) of MSM were aware of PrEP. In the 25 studies (N = 18,587) examining willingness, 54.5% (95% CI: 41.9-66.5) MSM indicated they were willing to use PrEP. The pooled prevalence of PrEP uptake from 9 studies (N = 6,575) was 4.9% (95% CI: 1.4-15.8%), while pooled estimates of adequate adherence from five studies (N = 2,344) among MSM on PrEP was 40.7% (95% CI: 20.0-65.2%). Subgroup analyses suggested studies conducted after 2015 (versus before) tended to report higher awareness and uptake. Awareness was highest for daily oral PrEP, followed by on-demand, and LAI PrEP; willingness to use was highest for LAI PrEP. The operationalization of willingness and adherence constructs varied across studies and complicated the interpretation of pooled estimates. This review revealed gaps in the PrEP care continuum among MSM in China, with relatively low awareness and uptake (in contrast to willingness and adherence) as the major potential barriers to widespread implementation and the need for a unified approach to defining and measuring PrEP outcomes.

Genotypic cluster analysis of Neisseria gonorrhoeae reveals a spectrum of sexual mixing including among HIV-serodiscordant men who have sex with men. Infect Dis (Lond) 2024:1-10. [PMID: 38907951 DOI: 10.1080/23744235.2024.2339864] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2023] [Accepted: 04/01/2024] [Indexed: 06/24/2024] Open
Abstract
BACKGROUND Men who have sex with men (MSM) are more vulnerable to acquiring sexually transmitted infections (STIs). In 2019, for instance, 74% of European Neisseria gonorrhoeae (Ng) cases among males affected MSM. A recent report by the World Health Organization showed that most of the 2020' interim targets to end STIs by 2030 had not been met. A broadened understanding of STI transmission networks could guide future elimination strategies and reduce the STI burden. Therefore, we used whole-genome sequencing (WGS) to determine Ng-clusters and assess sexual mixing. METHODS WGS was performed on Ng-isolates collected at the Medical University of Vienna, Austria and was used for core genome multi-locus sequencing typing cluster analysis. Epidemiologic and infection-specific details were extracted from medical records. RESULTS Genomic analysis and demographic data were available for 415 isolates, and 43.9% (182/415) were allocated to 31 Ng-clusters. Nine clusters comprised samples from heterosexual individuals only (women N = 4, human immunodeficiency virus (HIV)-negative men N = 49, HIV-positive man N = 1), nine clusters included MSM only (HIV-negative N = 22, HIV-positive N = 13) and 13 clusters included both heterosexuals and MSM (HIV-negative N = 75, HIV-positive N = 18). Current use of HIV pre-exposure prophylaxis (PrEP) was reported by 22.8% of MSM. In multivariate analysis, only 'MSM' predicted clustering with isolates from HIV-positive individuals (adjusted odds ratio 10.24 (95% CI 5.02-20.90)). CONCLUSIONS Sexual mixing of HIV-positive, HIV-negative MSM and non-MSM was frequently observed. Furthermore, HIV-serodiscordant clustering highlights the importance of PrEP rollout to avert HIV transmission. Our findings can inform future STI prevention strategies and continuous surveillance efforts are required to keep up with transmission dynamics.

Abstract
INTRODUCTION Pre-exposure prophylaxis (PrEP) against the human immunodeficiency virus (HIV) is an effective and safe preventive measure. However, it has not reached all target users who could benefit from it. The study aimed to understand the sociodemographic, clinical and behavioral baseline characteristics of PrEP users. As a secondary objective, the use of concomitant medication and drug consumption were described. METHODOLOGY Observational, retrospective and descriptive study of the sociodemographic, clinical and behavioral characteristics of the users who were included in the PrEP program of the Community of Madrid during the first two years of experience. RESULTS Two thousand two hundred fifty-six PrEP users were included, 99.0% men, with a mean age of 36.9 years (SD 8.68). 33.1% presented a sexually transmitted infection (STI) on the first visit, highlighting chlamydiasis and rectal gonococci. 70.4% reported using drugs associated with sex, and 42.4% participated in chemsex sessions in the last 3 months. A high percentage of users with concomitant medication was observed (37.6%), highlighting drugs related to mental health and alopecia. CONCLUSIONS A multidisciplinary approach is required to cover all the needs of PrEP users, including mental health evaluation measures and addiction treatment with the clinical approach.

Barriers and facilitators to uptake and persistence on prep among key populations in Southern Province, Zambia: a thematic analysis. BMC Public Health 2024; 24:1617.

Abstract
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.

Abstract
Background Antiretroviral chemoprophylaxis is a promising strategy for preventing the spread of human immunodeficiency virus (HIV). The knowledge of pre-exposure prophylaxis (PrEP) is required for intervention uptake and adherence to prevent the spread of HIV. This study aimed to decompose education-based inequalities in PrEP knowledge for HIV prevention among reproductive-aged women in Cote d'Ivoire. Methods A cross-sectional study design with a nationally representative sample of 12,934 women aged 15-49 years was analyzed from the 2021 Cote d'Ivoire Demographic and Health Survey. The survey was conducted between September to December, 2021. The outcome variable was the knowledge of PrEP for HIV prevention. Statistical analysis was conducted using percentage, concentration index, and Lorenz curve. The level of significance was set at p<0.05. Results A weighted prevalence of 14.5% (95% CI: 12.5-16.3%) was estimated for PrEP knowledge for HIV prevention. Overall, educated women had a higher knowledge of PrEP for HIV prevention (Conc. Index= 0.225; SE= 0.012; p<0.001). Across the levels of women's characteristics, the results showed higher PrEP knowledge for HIV prevention among educated women. Education (Contri: 40.7327%, Ec: 0.5390), exposure to internet (Contri: 20.1039%, Ec: 0.3484), place of residence (Contri: 12.9801%, Ec: -0.0537), household wealth (Contri: 10.0062%, Ec: 0.0642) and religion (Contri: 5.7509%, Ec: 0.0354) were positive contributors to PrEP knowledge for HIV prevention. On the other hand, age (Contri: -8.8298%, Ec: -0.0950) and region (Contri: -3.5942, Ec: -0.0768) were negative contributors to PrEP knowledge regarding HIV prevention among women of reproductive age in Cote d'Ivoire. Conclusion There is limited knowledge of PrEP for HIV prevention among women in Cote d'Ivoire. Educated women had greater knowledge of PrEP for HIV prevention. The results of this study could guide interventions targeted to enhance the knowledge of PrEP as an HIV prevention option.

Abstract
Background Rising hepatitis C and B virus (HCV and HBV) rates have been reported in men who have sex with men (MSM) and transgender women (TGW). This study characterizes HCV and HBV infections longitudinally among 2,496 MSM/TGW aged 18-50 years and at risk for HIV acquisition enrolled in an HIV-1 vaccine trial in 18 U.S. cities between 2009-2013. Methods Participants completed behavioral surveys, HIV testing, and blood collection over 24 months. Of the 2,397 participants who consented for future testing, 1,792 (74.8%) had available paired stored blood samples at baseline and a later timepoint (Month 24 [N = 999]; if unavailable, M12 [N = 775] or M15 [N = 18]). Results Among 1,792 participants, 98.1% were MSM, 0.8% were TGW, and the median age was 30 years (IQR 24, 40). Participants reported a median number of 3 male sex partners (IQR 1,5) within the past 3 months. Condomless insertive anal sex was reported by 55.8% and condomless receptive anal sex by 46.7%.1.3% reported injection drug use. During follow-up, 1.4% reported pre-exposure prophylaxis (PrEP) use. At baseline 11/1792 (0.61%) participants had HCV infection (HCV AB positive, RNA detectable), with all having persistent detectable RNA and chronic HCV infection at follow-up. Phylogenetic analysis showed no clusters of HCV infection. 8 participants had HCV AB positive, RNA undetectable at baseline and follow-up, representing past HCV infection with clearance; only 2 acquired HCV, which cleared over 12-24 months. At baseline, 2 participants (2/1792 = 0.11%) had positive HBsAg, indicating chronic HBV infection. Over 12-24 months, 4 (4/1790, 0.22%) developed HBsAg positivity; these participants had HBcAB positivity at baseline, thereby likely representing reactivation. There were no new HBV infections during follow-up. Conclusion Among 1,792 men who have sex with men and transgender women aged 18-50 years and at risk for HIV acquisition enrolled in a U.S. HIV-1 vaccine trial, incident hepatitis C infection rates were extremely low, with no cases of incident hepatitis B infection. These rates of incident HCV infection and HBSAg positivity are lower than previously reported among MSM/TGW.

Abstract
SUMMARYThe human immunodeficiency virus (HIV) epidemic remains a formidable global health concern, with 39 million people living with the virus and 1.3 million new infections reported in 2022. Despite anti-retroviral therapy's effectiveness in pre-exposure prophylaxis, its global adoption is limited. Broadly neutralizing antibodies (bNAbs) offer an alternative strategy for HIV prevention through passive immunization. Historically, passive immunization has been efficacious in the treatment of various diseases ranging from oncology to infectious diseases. Early clinical trials suggest bNAbs are safe, tolerable, and capable of reducing HIV RNA levels. Although challenges such as bNAb resistance have been noted in phase I trials, ongoing research aims to assess the additive or synergistic benefits of combining multiple bNAbs. Researchers are exploring bispecific and trispecific antibodies, and fragment crystallizable region modifications to augment antibody efficacy and half-life. Moreover, the potential of other antibody isotypes like IgG3 and IgA is under investigation. While promising, the application of bNAbs faces economic and logistical barriers. High manufacturing costs, particularly in resource-limited settings, and logistical challenges like cold-chain requirements pose obstacles. Preliminary studies suggest cost-effectiveness, although this is contingent on various factors like efficacy and distribution. Technological advancements and strategic partnerships may mitigate some challenges, but issues like molecular aggregation remain. The World Health Organization has provided preferred product characteristics for bNAbs, focusing on optimizing their efficacy, safety, and accessibility. The integration of bNAbs in HIV prophylaxis necessitates a multi-faceted approach, considering economic, logistical, and scientific variables. This review comprehensively covers the historical context, current advancements, and future avenues of bNAbs in HIV prevention.

Abstract
Pre-exposure prophylaxis (PrEP) is a pivotal intervention among HIV prevention strategies. We aimed to narratively revise the topic of HIV acute infection in the setting of PrEP exposure with a focus on diagnostic options, clinical features, and future PrEP perspectives, with a particular focus on users with high adherence to PrEP. We searched the main databases (PubMed, Embase, and Scopus) with the keywords "PrEP" or "Pre-Exposure Prophylaxis" and "HIV" or "PLWH" and "breakthrough" or "acute infection" or "primary infection". We included all randomized clinical trials and non-experimental studies (both case reports and observational studies) ever published. In the present narrative review, we revise the diagnostic challenges related to HIV diagnosis in the setting of PrEP and the clinical characteristics and symptoms of breakthrough infections. We discuss the management of acute HIV infection during PrEP and the new challenges that arise from the use of long-acting drugs for PrEP. Our review underlines that although extremely rare, HIV seroconversions are still possible during PrEP, even in a context of high adherence. Efforts to promptly identify these events must be included in the PrEP follow-up in order to minimize the chance of overlooked HIV breakthrough infections and thus exposure to suboptimal concentrations of antiretrovirals.

Abstract
Pre-exposure prophylaxis (PrEP) of human immunodeficiency virus (HIV) represents the most significant breakthrough in the HIV prevention field over the past decade. PrEP is an effective strategy in preventing the transmission of HIV across all populations, providing high adherence. The current PrEP options include oral daily and on-demand tenofovir-based regimens, long-acting injections of cabotegravir, and a 1-month dapivirine vaginal ring. As a component of a multifaceted prevention approach, extensive deployment of PrEP holds the promise to significantly reduce the global HIV epidemic. Nonetheless, barriers still exist in terms of uptake, adherence, and persistence, while disparities in PrEP accessibility remain a concern.

[PMID: 38851649 DOI: 10.1007/s10461-024-04387-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 05/16/2024] [Indexed: 06/10/2024]
Abstract
Structural racism and discrimination (SRD) is deeply embedded across U.S. healthcare institutions, but its impact on health outcomes is challenging to assess. The purpose of this systematic literature review is to understand the impact of SRD on pre-exposure prophylaxis (PrEP) care continuum outcomes across U.S. populations who could benefit from HIV prevention. Guided by PRISMA guidelines, we conducted a systematic review of the published literature up to September 2023 using PubMed and PsycInfo and included peer-reviewed articles meeting inclusion criteria. At least two authors independently screened studies, performed quality assessments, and abstracted data relevant to the topic. Exposure variables included race/ethnicity and any level of SRD (interpersonal, intra- and extra-organizational SRD). Outcomes consisted of any steps of the PrEP care continuum. A total of 66 studies met inclusion criteria and demonstrated the negative impact of SRD on the PrEP care continuum. At the interpersonal level, medical mistrust (i.e., lack of trust in medical organizations and professionals rooted from current or historical practices of discrimination) was negatively associated with almost all the steps across the PrEP care continuum: individuals with medical mistrust were less likely to have PrEP knowledge, adhere to PrEP care, and be retained in care. At the intra-organizational level, PrEP prescription was lower for Black patients due to healthcare provider perception of higher sex-risk behaviors. At the extra-organizational level, factors such as homelessness, low socioeconomic status, and incarceration were associated with decreased PrEP uptake. On the other hand, healthcare provider trust, higher patient education, and access to health insurance were associated with increased PrEP use and retention in care. In addition, analyses using race/ethnicity as an exposure did not consistently show associations with PrEP continuum outcomes. We found that SRD has a negative impact at all steps of the PrEP care continuum. Our results suggest that when assessing the effects of race/ethnicity without the context of SRD, certain relationships and associations are missed. Addressing multi-level barriers related to SRD are needed to reduce HIV transmission and promote health equity.

Low clinical impact of HIV drug resistance mutations in oral pre-exposure prophylaxis: a systematic review and meta-analysis. AIDS Res Ther 2024; 21:37. [PMID: 38844950 PMCID: PMC11155065 DOI: 10.1186/s12981-024-00627-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2024] [Accepted: 05/29/2024] [Indexed: 06/10/2024] Open
Abstract
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.

Abstract
This study aimed to characterize the epidemiological aspects of PrEP use and barriers to accessing this prophylaxis. This cross-sectional study was conducted between January 2021 and April 2022, encompassing 140 PrEP users treated at the Testing and Counseling Center (CTA) in Campo Grande, Mato Grosso do Sul. Data on sociodemographic characteristics and factors associated with PrEP discontinuation were obtained using a standardized questionnaire. Most PrEP users were cisgender men (92.00%), predominantly white (51.00%), over 30 years of age (56.50%), homosexual-oriented (76.50%), and had a minimum of 12 years of education (77.50%). Approximately 60.00% admitted to inconsistent condom use in recent sexual encounters, primarily involving anal intercourse. Approximately 88.00% perceived themselves as at risk of contracting STIs in the upcoming year. Regarding new presentation forms, 54.00% indicated a willingness to use "on-demand PrEP," and 92.00% expressed interest in using "injectable PrEP." After 6 months of follow-up, 43.60% (95.00% CI: 35.50-52.00) discontinued PrEP use, primarily due to changes in sexual behavior (38.30%) and difficulties accessing healthcare services (21.28%). This study underscores the need to involve diverse key populations and highlights the significance of PrEP as an ongoing monitoring strategy for HIV/STI prevention in addition to the importance of incorporating new formulations such as daily oral PrEP into the Brazilian National Health System (SUS).

Abstract
New HIV infections disproportionately affect young men who have sex with men (YMSM). PrEP is effective in preventing HIV acquisition; however, adherence is critical and is often suboptimal among YMSM. Interventions addressing the unique PrEP adherence challenges faced by YMSM are needed. We conducted qualitative interviews with 20 HIV-negative, YMSM (ages 15-24) with a PrEP indication and 11 healthcare professionals to inform adaption of a PrEP adherence intervention (Life-Steps for PrEP) for YMSM. We explored environmental, healthcare, and individual factors influencing uptake, adherence, attitudes, and perspectives (including desired modifications) on the Life-Steps intervention. Interviews were analyzed using content analysis. Of YMSM study participants (mean age 21.6) 55% were White, 15% Hispanic, and 5% Black. Most YMSM were PrEP-experienced (70%). Healthcare professionals (6 prescribers, 1 nurse, 2 health educators, 2 other/unspecified) averaged 6.9 years of experience caring for YMSM. All described stigma as a barrier to PrEP; YMSM expressed concern around being perceived as "risky" and concern about inadvertent PrEP disclosure if family/friends found their medication, or if parental insurance was used. Difficulty with planning for potential adherence challenges were identified by both groups. YMSM highlighted benefits of a nurse-led intervention (i.e., adding "legitimacy"), but stressed need for nonjudgmental, "savvy" interventionists. YMSM expressed a desire for comprehensive YMSM-specific sexual health information. These findings informed modification and expansion of Life-Steps content. Results highlight key potential barriers, many of which center around privacy. Content that addresses PrEP stigma, disclosing PrEP use, navigating insurance, and planning ahead in a nonjudgmental environment by trusted providers emerged as important components of a YMSM-focused delivery of Life-Steps for PrEP.

Abstract
BACKGROUND The aim of our study was to evaluate real-world implementation of Slovenia's national HIV PrEP programme, which is fully covered by our national health insurance. METHODS In retrospective cohort study we analysed the data from all men who have sex with men (MSM) who were enrolled in PrEP programme of our clinic between 1 January 2022 and 31 December 2022. RESULTS A total of 190 MSM with an average age of 36.7 years were included in our analysis. 151 (79.5%) decided for event-driven PrEP and 39 (20.5%) opted for daily PrEP. Self-reported adherence was 95%. Among eligibility criteria, unprotected sex was the most common one, followed by one or more STIs in the past, use of chemsex and use of HIV post-exposure prophylaxis in the past. No new cases of HIV infection and no significant deterioration of kidney or liver function were observed during the follow-up. Sixty-seven episodes of STIs were diagnosed and treated. Gonorrhea (32), chlamydia (14), and Mpox (10) were the most common ones. CONCLUSIONS PrEP was successfully implemented into everyday clinical practice, proving to be both safe and effective. High number of diagnosed STIs suggests that the PrEP programme, combined with STI screening and vaccination, provides a strong public health impact among MSM in Slovenia.

Abstract
BACKGROUND Emergency departments (EDs) provide care to patients at increased risk for acquiring HIV, and for many of them, the ED serves as their sole point of entry into the healthcare system. We implemented the HIV PreventED Program to increase access to HIV prevention services for ED patients. SETTING ED in Oakland, CA with an annual census of 57,000 visits. METHODS This cross-sectional study evaluated the first 9 months of the HIV PreventED Program. In this program, a navigator surveyed adult ED patients who tested HIV negative to determine their risk for acquiring HIV infection, incorporating HIV prevention counseling into their assessments. Patients at higher risk for acquiring HIV were referred to outpatient prevention services, if interested. The primary outcome measure was the number and proportion of ED patients at higher risk for acquiring HIV who followed up for outpatient prevention services. RESULTS In this study, 1233 patients who tested HIV negative were assessed by the navigator and received ED-based HIV prevention counseling. Of these, 193 (15.7%) were identified at higher risk and offered an outpatient referral for prevention services, of which 104 accepted (53.9%), 23 (11.9%) attended the referral, and 13 (6.7%) were prescribed preexposure prophylaxis (PrEP). The median time to linkage was 28 days (interquartile range 15-41 days). CONCLUSION A navigator focused on providing ED-based HIV prevention counseling and linkage to outpatient services is feasible. Strategies to more efficiently identify ED patients at higher risk for HIV acquisition, such as automated identification of risk data from the electronic health record, and policies to improve follow-up and the receipt of PrEP, such as same-day PrEP initiation, should be prospectively evaluated.

Abstract
Integrase inhibitors and tenofovir alafenamide have become a mainstay in modern antiretroviral therapy; more recently, they have been implicated as causing increased weight gain beyond what may be expected with the "return to health" phenomenon. Some patients, namely those assigned female at birth, of the black race, or with lower baseline CD4 counts, may be more likely to experience weight gain. This review outlines existing evidence linking the agents to excessive weight as well as ongoing efforts to combat these effects.

Abstract
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.

Abstract
HIV Pre-exposure Prophylaxis (PrEP) uptake among transgender (TG) people and gay men and other men who have sex with men (MSM) remains low, despite South Africa being the first African country to approve PrEP. This mixed-methods study used a two-phase explanatory sequential design: (1) quantitative analysis of cross-sectional surveys followed by (2) qualitative in-depth interviews. This study explored facilitators and barriers to PrEP uptake to identify strategies to increase utilization in these key populations. We conducted 202 cross-sectional surveys and 20 in-depth interviews between July 2021 and March 2022 in Soshanguve, Tshwane, Gauteng. Quantitative data were analyzed using univariate logistic regression; thematic analysis was performed for qualitative data. Findings show high willingness to use PrEP but low PrEP uptake. We outline strategies to facilitate PrEP use: (1) demystify daily PrEP by deploying community-engaged PrEP education campaigns; (2) capitalize on existing peer networks; and (3) expand accessible and culturally responsive PrEP service delivery models. We provide feasible recommendations to close the PrEP uptake gap in these key populations in South Africa.

Abstract
OBJECTIVE To evaluate the effect of preexposure prophylaxis (PrEP) initiation on bacterial sexually transmitted infection (STI) occurrence (overall; chlamydia; gonorrhea; syphilis), in MSM. DESIGN Systematic review and meta-analysis. METHODS Systematic searches were performed in PubMed, Embase, and Scopus without language restrictions until 1 February 2023. We sought studies reporting data for the estimation of incidence rate ratios (IRR), prevalence ratios or cumulative incidence ratios (the latter in equal time periods before and after PrEP initiation) regarding bacterial STI occurrence. Separate analyses were performed overall for any STI, syphilis, chlamydia and gonorrhea (overall; rectal; urethral; pharyngeal for the two latter conditions); ratios greater than unity denoted increase in STI occurrence after PrEP initiation. RESULTS Twenty-three eligible studies with 11 776 participants (age range: 18-71 years) with a median follow-up of 12 months were included. Overall, PrEP initiation was associated with a significant increase in the occurrence of any STI (pooled effect size: 1.15, 95% confidence interval (CI): 1.04-1.26), any gonorrhea (pooled effect size: 1.17, 95% CI: 1.02-1.34), any chlamydia (pooled effect size: 1.31, 95% CI: 1.09-1.58) and rectal chlamydia (pooled effect size: 1.31, 95% CI: 1.05-1.64), whereas a borderline increase was found in urethral chlamydia (pooled effect size: 1.25, 95% CI: 0.99-1.60, P = 0.064). Changes in pharyngeal chlamydia and site-specific gonorrhea occurrence did not reach statistical significance. Syphilis showed virtually no change after PrEP initiation (pooled effect size: 0.99, 95% CI: 0.72-1.37). CONCLUSION These results highlight the need for more comprehensive, accessible STI testing to tackle bacterial STI infections in PrEP users.

A Pilot Randomized Controlled Trial of an mHealth Intervention to Improve PrEP Adherence Among Young Sexual Minority Men. AIDS Behav 2024:10.1007/s10461-024-04374-3. [PMID: 38816592 DOI: 10.1007/s10461-024-04374-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 05/08/2024] [Indexed: 06/01/2024]
Abstract
This randomized controlled study assessed the feasibility, acceptability, and preliminary impact of the PrEP iT! mHealth intervention designed to improve PrEP adherence among young men who have sex with men (YMSM). A national sample of 80 YMSM in the U.S. (Mage = 25 years; 54% racial/ethnic minority), recruited through social media ads, were randomized to either the PrEP iT! or usual PrEP care conditions. Participants completed online surveys and submitted self-collected dried blood sample (DBS) data as measures of PrEP adherence. Differences in PrEP adherence across treatment arms and between participants with high versus low engagement in PrEP iT! were assessed. Retention was high at the three (94%) and six (93%) month assessment, and participants in PrEP iT! reported satisfactory acceptability of the intervention. There were no significant differences in self-reported or DBS-derived PrEP adherence between randomized groups. However, YMSM in the PrEP iT! group with high PrEP adherence (the equivalent of four or more doses/week through self-report and DBS-derived measures) demonstrated significantly higher engagement in the intervention than those with low PrEP adherence (the equivalent of 3 or fewer doses/week). Overall, the PrEP iT! intervention demonstrated strong feasibility and acceptability. The finding that high PrEP iT! intervention engagement was associated with protective levels of PrEP adherence suggests it is a viable adherence support tool that should be further evaluated in definitive trial among YMSM who need basic support, or as part of a more comprehensive adherence support package for those who need greater assistance.Trial registration Clinical Trials # NCT04509076 (registered August 10, 2020).

Cancer in people who identify as lesbian, gay, bisexual, transgender, queer, or gender-nonconforming. Cancer 2024. [PMID: 38818898 DOI: 10.1002/cncr.35355] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2024] [Revised: 04/04/2024] [Accepted: 04/17/2024] [Indexed: 06/01/2024]
Abstract
BACKGROUND Individuals who identify as lesbian, gay, bisexual, transgender, queer, intersex, or gender-nonconforming (LGBTQ+) experience discrimination and minority stress that may lead to elevated cancer risk. METHODS In the absence of population-based cancer occurrence information for this population, this article comprehensively examines contemporary, age-adjusted cancer risk factor and screening prevalence using data from the National Health Interview Survey, Behavioral Risk Factor Surveillance System, and National Youth Tobacco Survey, and provides a literature review of cancer incidence and barriers to care. RESULTS Lesbian, gay, and bisexual adults are more likely to smoke cigarettes than heterosexual adults (16% compared to 12% in 2021-2022), with the largest disparity among bisexual women. For example, 34% of bisexual women aged 40-49 years and 24% of those 50 and older smoke compared to 12% and 11%, respectively, of heterosexual women. Smoking is also elevated among youth who identify as lesbian, gay, or bisexual (4%) or transgender (5%) compared to heterosexual or cisgender (1%). Excess body weight is elevated among lesbian and bisexual women (68% vs. 61% among heterosexual women), largely due to higher obesity prevalence among bisexual women (43% vs. 38% among lesbian women and 33% among heterosexual women). Bisexual women also have a higher prevalence of no leisure-time physical activity (35% vs. 28% among heterosexual women), as do transgender individuals (30%-31% vs. 21%-25% among cisgender individuals). Heavier alcohol intake among lesbian, gay, and bisexual individuals is confined to bisexual women, with 14% consuming more than 7 drinks/week versus 6% of heterosexual women. In contrast, prevalence of cancer screening and risk reducing vaccinations in LGBTQ+ individuals is similar to or higher than their heterosexual/cisgender counterparts except for lower cervical and colorectal cancer screening among transgender men. CONCLUSIONS People within the LGBTQ+ population have a higher prevalence of smoking, obesity, and alcohol consumption compared to heterosexual and cisgender people, suggesting a higher cancer burden. Health systems have an opportunity to help inform these disparities through the routine collection of information on sexual orientation and gender identity to facilitate cancer surveillance and to mitigate them through education to increase awareness of LGBTQ+ health needs.

[PMID: 38575314 PMCID: PMC11187399 DOI: 10.1136/sextrans-2023-055917] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2023] [Accepted: 03/09/2024] [Indexed: 04/06/2024] Open
Abstract
INTRODUCTION The government-funded pre-exposure prophylaxis (PrEP) programme was targeted to those aged under 30 years or serodiscordant couples and implemented in September 2018-October 2020 in Taiwan. The study aimed to examine the effectiveness of the programme and the relationship between sexually transmitted disease (STD) and HIV seroconversion. METHODS This study was a retrospective cohort analysis with questionnaires designed for participants who joined the aforementioned programme in the PrEP-designated hospitals. The questionnaires included sociodemographic factors, sexual risk behaviours, number and types of sexual partners, and usage of narcotics filled in at the beginning of the programme and every 3 months. The McNemar test was used for the paired questionnaire analysis. The HIV seroconversion status among STD-notified patients nationwide was confirmed by using the data linkage method, followed up until October 2021 with stratification of PrEP programme participation or not. RESULTS The programme recruited 2155 people. 11 participants (0.5%) had seroconversion within the programme, while 26 (1.2%) had seroconversion after withdrawing from the programme. Overall, 1892 subjects with repeated questionnaires were included in the analysis for behaviour changes with median follow-up of 289 days. After joining the programme, 94.7% of them claimed that they had sexual behaviours: the rate of those who had condomless sex rose to 5.5% (p<0.001) and the rate of those who used narcotics decreased to 2% (p<0.001), compared with their response in the pre-questionnaire. Notably, the frequency of non-use of narcotics in recent 3 months increased from 16.9% to 38.4% in the pre-questionnaire and post-questionnaire responses, among the 177 who had claimed narcotics usage in recent 12 months (p=0.003). More HIV seroconversion was found among patients with STD who did not join the programme than those who joined the programme (8.7% vs 4.9%, p=0.031). CONCLUSIONS The government-funded programme showed HIV case reduction and positive changes in health behaviours except for condomless sex which had increased prevalence. The reduction of HIV cases was also observed among people with STD. More resources should be allocated to the PrEP programme.

Abstract
For people at risk of HIV infection, pre-exposure prophylaxis (PrEP) can reduce the risk of infection in anticipation of exposure to HIV. The effectiveness of PrEP relies upon a user's adherence to their PrEP regimen. We sought to assess the effect of PrEP adherence interventions compared to usual care or another intervention for people at risk of HIV. We searched electronic databases from 2010 onwards for randomized controlled trials (RCTs) involving persons at risk of HIV randomized to an adherence promoting intervention vs usual care or another intervention. We used network meta-analyses to compare PrEP adherence for all participant populations. Certainty of evidence was assessed using Confidence in Network Meta-Analysis (CINeMA). 21 trials (N = 4917) were included in qualitative analysis (19 in network meta-analyses (N = 4101)). HIV self-testing interventions with adherence feedback elements improved adherence compared to usual care (risk ratio (RR): 1.83, 95%CI 1.19, 2.82). In contrast, HIV self-testing alone was inferior to HIV self-testing with adherence feedback (RR: 0.58, 95%CI 0.37-0.92). Reminders alone also were inferior to HIV self-testing with adherence feedback on adherence (RR: 0.53, 95%CI 0.34-0.84) and had similar effects on adherence as usual care (RR: 0.98, 95%CI: 0.86-1.11). Interventions with only one component were inferior for adherence than those with two components (RR: 0.74, 95%CI 0.62-0.88) and those with three components (RR: 0.78, 95%CI 0.65-0.93). The certainty of evidence was moderate for HIV self-testing plus adherence feedback and interventions with two or three components. When designing future PrEP adherence interventions, we recommend strategies with more than one but no more than three components.
