This review summarizes quantitative preference elicitation methods (PEM) and how they can be applied to improve the delivery and uptake of HIV prevention and treatment interventions.Recent findings: PEM are increasingly applied in HIV implementation research; however, discrete choice experiments (DCEs) have predominated. Beyond DCEs, there are other underutilized PEM that may improve the reach and effectiveness of HIV prevention and treatment interventions among individuals by prioritizing their barriers to engagement and determining which attributes of interventions and delivery strategies are most valued. PEM can also enhance the adoption and sustained implementation of strategies to deliver HIV prevention and treatment interventions by assessing which attributes are the most acceptable and appropriate to key stakeholders.Summary: Greater attention to and incorporation of patient's and stakeholders' preferences for HIV prevention and treatment interventions and their delivery has the potential to increase the number of persons accessing and retained in HIV prevention and treatment services.","PeriodicalId":10949,"journal":{"name":"Current Opinion in HIV and AIDS","volume":"18 1","pages":"32-45"},"PeriodicalIF":4.1,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9772083/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10141862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Against the backdrop of the impact of NGOs, is the recognition of the unique role that local NGOs bring to the HIV response, drawing from their deep understanding of the context and knowledge of local health problems.Recent findings: The Centre for Infectious Disease Research in Zambia (CIDRZ) is one such NGO. Through various implementation science research and programs, CIDRZ has supported the Zambian government's HIV response. As Zambia moves closer to epidemic control, understanding reasons for patient disengagement from care and patient preferences for HIV care demonstrated by CIDRZ have contributed to global and national HIV treatment and care guidelines.Summary: This paper offers a case study for how NGOs like CIDRZ can serve as health system-wide catalyst to identify, integrate, and scale up evidence-based practices for HIV prevention, care, and treatment. It draws from the public health literature, CIDRZ extensive program and research experience and implementation science theory, to illustrate key strategies that can be deployed by local NGOs to spark innovation, quality improvement, and support governments to achieve and sustain HIV epidemic control.","PeriodicalId":10949,"journal":{"name":"Current Opinion in HIV and AIDS","volume":"18 1","pages":"52-56"},"PeriodicalIF":4.1,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10129226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To improve the effectiveness of HIV prevention and treatment service implementation, we need to understand what drives human behaviour and decision-making around HIV service use. This review highlights current thinking in the social sciences, emphasizing how understanding human behaviour can be leveraged to improve HIV service delivery.Recent findings: The social sciences offer rich methodologies and theoretical frameworks for investigating how factors synergize to influence human behaviour and decision-making. Social-ecological models, such as the Behavioural Drivers Model (BDM), help us conceptualize and investigate the complexity of people's lives. Multistate and group-based trajectory modelling are useful tools for investigating the longitudinal nature of peoples HIV journeys. Successful HIV responses need to leverage social science approaches to design effective, efficient, and high-quality programmes.Summary: To improve our HIV response, implementation scientists, interventionists, and public health officials must respond to the context in which people make decisions about their health. Translating biomedical efficacy into real-world effectiveness is not simply finding a way around contextual barriers but rather engaging with the social context in which communities use HIV services.","PeriodicalId":10949,"journal":{"name":"Current Opinion in HIV and AIDS","volume":"18 1","pages":"46-51"},"PeriodicalIF":4.1,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9799045/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10141867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review article synthesizes recent evidence on stigma and its implications for HIV service design and delivery. Given the intersectional nature of stigma, we will focus on HIV stigma as well as related forms of stigma based on one's race, sexual identity, gender identity and other identities.Recent findings: Stigma remains a barrier to achieving equity in HIV services. Individualistic measures of stigma remain influential and are associated with barriers to accessing HIV health services. Recent work also highlights stigma measured at a structural level and its impact on HIV services contexts. Individuals situated at intersections of marginalized identities continue to face greatest injustices, and although intersectional approaches have been adapted to design services at a micro level, few focus on structural change. Recent evidence for mitigating stigma indicates some success for psychosocial interventions that target internalized stigma. Furthermore, community-led approaches show promise in addressing stigma that manifests in HIV health services settings.Summary: Interventions that address individual-level stigma and structural stigma are needed.

Often, we expect randomized trial findings to be generalizable across populations and settings where products will be delivered, without consideration of key contextual drivers that could impact effectiveness. Moreover, researchers and policy-makers generally discount products with varied effect sizes across contexts, rather than explicating the drivers of these differences and using them to inform equitable product choice and delivery. We conducted a review of the recent HIV prevention research to advance considerations of context in choices of when, why, and how to implement biomedical HIV prevention products, with a particular focus on daily oral preexposure prophylaxis (PrEP) and the dapivirine vaginal ring (DPV).Recent findings: Findings across recent studies of PrEP and DPV emphasize that products that do not work well in one context might be highly desirable in another. Key contextual drivers of PrEP and DPV effectiveness, use, and implementation include population, health system, cultural, and historical factors. We recommend conceptualization, measurement, and analysis approaches to fully understand the potential impact of context on prevention product delivery. Execution of these approaches has real-world implications for HIV prevention product choice and could prevent the field from dismissing biomedical HIV prevention products based on trial findings alone.Summary: Ending the HIV epidemic will require tailored, person-centered, and equitable approaches to design, implement, and evaluate HIV prevention products which necessitates considerations of context in ongoing research and implementation.","PeriodicalId":10949,"journal":{"name":"Current Opinion in HIV and AIDS","volume":"18 1","pages":"1-11"},"PeriodicalIF":4.1,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9757852/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10129223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the effective use of bNAbs is impacted by the presence of preexisting virological resistance and the potential to develop new resistance during treatment. With several bNAb clinical trials underway, sensitive and scalable assays are needed to screen for resistance. This review summarises the data on resistance from published clinical trials using the bNAbs 10-1074 and 3BNC117 and evaluates current approaches for detecting bNAb sensitivity as well as their limitations.Recent findings: Analyses of samples from clinical trials of 10-1074 and 3BNC117 reveal viral mutations that emerge on therapy which may result in bNAb resistance. These mutations are also found in some potential study participants prior to bNAb exposure. These clinical data are further informed by ex-vivo neutralisation assays which offer an alternative measure of resistance and allow more detailed interrogation of specific viral mutations. However, the limited amount of publicly available data and the need for better understanding of other viral features that may affect bNAb binding mean there is no widely accepted approach to measuring bNAb resistance.Summary: Resistance to the bNAbs 10-1074 and 3BNC117 may significantly impact clinical outcome following their therapeutic administration. Predicting bNAb resistance may help to lower the risk of treatment failure and therefore a robust methodology to screen for bNAb sensitivity is needed.","PeriodicalId":10949,"journal":{"name":"Current Opinion in HIV and AIDS","volume":"17 6","pages":"352-358"},"PeriodicalIF":4.1,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9594129/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10194705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This increased risk is thought to be due to both traditional (for example, smoking, diabetes) and HIV-specific (for example, inflammation, persistent immune activation) risk factors. This review focuses on the potential for statin therapy to mitigate this increased risk.Recent findings: Several randomized clinical trials have demonstrated that statins, a class of lipid-lowering medications, are effective as a primary CVD prevention strategy among people without HIV. Among PWH, statins have been shown to lower cholesterol, exert immunomodulatory effects, stabilize coronary atherosclerotic plaque, and even induce plaque regression.Summary: Prevention of CVD among the aging population of people with controlled, but chronic, HIV is vital. Data exploring primary prevention in this context are thus far limited. The Randomized Trial to Prevent Vascular Events in HIV (REPRIEVE) is ongoing; this trial will inform the field by investigating the effects of pitavastatin calcium as a primary prevention strategy for major adverse cardiovascular events among PWH on antiretroviral therapy (ART) at low-to-moderate traditional CVD risk.","PeriodicalId":10949,"journal":{"name":"Current Opinion in HIV and AIDS","volume":"17 5","pages":"293-300"},"PeriodicalIF":4.5,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/08/40/cohiv-17-293.PMC9415230.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9121707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this review, we will compare back-to-back the immunological and virological features underlying viral suppression in elite controllers and PTCs, and explore their possible contributions to the HIV-1 cure research.Recent findings: HIV-1 control in elite controllers shows hallmarks of an effective antiviral response, favored by genetic background and possibly associated to residual immune activation. The immune pressure in elite controllers might select against actively transcribing intact proviruses, allowing the persistence of a small and poorly inducible reservoir. Evidence on PTCs is less abundant but preliminary data suggest that antiviral immune responses may be less pronounced. Therefore, these patients may rely on distinct mechanisms, not completely elucidated to date, suppressing HIV-1 transcription and replication.Summary: PTCs and elite controllers may control HIV replication using distinct pathways, the elucidation of which may contribute to design future interventional strategies aiming to achieve a functional cure.","PeriodicalId":10949,"journal":{"name":"Current Opinion in HIV and AIDS","volume":"17 5","pages":"325-332"},"PeriodicalIF":4.1,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/ea/79/cohiv-17-325.PMC10004771.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10139683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
