RESUMEN

ABSTRACT: Black women are essential to ending the HIV epidemic in the United States; yet prevention, access, testing, and structural racism affect how HIV disproportionately affects them. Limited public health research focuses on Black women attending Historically Black Colleges and Universities (HBCUs) and the ability to address HIV prevention, such as pre-exposure prophylaxis (PrEP) uptake. PrEP is a once-daily oral pill used to prevent HIV transmission and has suboptimal uptake within the Black community. This generic qualitative descriptive analysis identifies the barriers and facilitators of PrEP uptake among Black women attending an HBCU using the health belief model. Overall, 22 Black college women participated in a 60-minute focus group. Emergent categories were as follows: (a) Barriers-stigma, cost, and side effects; (b) Facilitators-PrEP's effectiveness, exposure to HIV, and unprotected sex. Our findings can inform future efforts to increase PrEP uptake among Black women attending an HBCU.

RESUMEN

ABSTRACT: In the U.S. South, over half of new HIV diagnoses occur among Black Americans with research lagging for women who face increased HIV rates and low PrEP uptake, among other health inequities. Community engaged research is a promising method for reversing these trends with established best practices for building infrastructure, implementing research, and translating evidence-based interventions into clinical and community settings. Using the 5Ws of Racial Equity in Research Framework (5Ws) as a racial equity lens, the following paper models a review of a salon-based intervention to improve PrEP awareness and uptake among Black women that was co-developed with beauty salons, stylists, and Black women through an established community advisory council. In this paper we demonstrate how the 5Ws framework was applied to review processes, practices, and outcomes from a community-engaged research approach. The benefits of and challenges to successful collaboration are discussed with insights for future research and community impact.

RESUMEN

To maximise the benefits of HIV self-testing (HIVST), it is critical to support self-testers in the testing process and ensure that they access appropriate prevention and care. To summarise systems and tools supporting HIVST (hereafter, 'support systems') and categorise them for future analysis, we synthesised the global data on HIVST support systems and proposed a typology. We searched five databases for articles reporting on one or more HIVST support systems and included 314 publications from 224 studies. Across 189 studies, there were 539 reports of systems supporting HIVST use; while across 115 studies, there were 171 reports of systems supporting result interpretation. Most commonly, these were pictorial instructions, followed by in-person demonstrations and in-person assistance while self-testing or reading self-test results. Less commonly, virtual interventions were also identified, including online video conferencing and smartphone apps. Smartphone-based automated result readers have been used in the USA, China, and South Africa. Across 173 studies, there were 987 reports of systems supporting post-test linkage to care; most commonly, these were in-person referrals/counselling, written referrals, and phone helplines. In the USA, Bluetooth beacons have been trialled to monitor self-test use and facilitate follow-up. We found that, globally, HIVST support systems use a range of methods, including static media, virtual tools, and in-person engagement. In-person and printed approaches were more common than virtual tools. Other considerations, such as linguistic and cultural appropriateness, may also be important in the development of effective HIVST programs.

RESUMEN

Monoclonal antibodies have widespread applications in disease treatment and antigen detection. They are traditionally produced using mammalian cell expression system, which is not able to satisfy the increasing demand of these proteins at large scale. Baculovirus expression vector system (BEVS) is an attractive alternative platform for the production of biologically active monoclonal antibodies. In this chapter, we demonstrate the production of an HIV-1 broadly neutralizing antibody b12 in BEVS. The processes including transfer vector construction, recombinant baculovirus generation, and antibody production and detection are described.

RESUMEN

ABSTRACT: Speed of processing (SOP) cognitive training may improve indicators of the quality of life (QoL) in people living with HIV. In this 2-year, longitudinal, randomized, controlled trial, 216 participants ages 40 years and older with HIV-associated neurocognitive disorder or borderline HIV-associated neurocognitive disorder were assigned to one of three groups: (a) 10 hr of SOP training (n = 70); (b) 20 hr of SOP training (n = 73), or (c) 10 hr of internet navigation control training (a contact control group; n = 73). Participants completed several QoL measures at baseline, posttest, and Year 1 and Year 2 follow-ups. Using linear mixed-effect models, no strong pattern of training effects across QoL outcomes was apparent, with small-magnitude, nonsignificant, between-group differences in depression, locus of control, and Medical Outcomes Study-HIV scales. In conclusion, despite prior work showing some transfer of SOP cognitive training improving QoL, that was not observed. Implications for research and practice are posited.

RESUMEN

The magnitude of the HIV-1 epidemic in Nigeria is second only to the subtype C epidemic in South Africa, yet the subtypes prevalent in Nigeria require further characterization. A panel of 50 subtype G and 18 CRF02_AG Nigerian HIV-1 pseudoviruses (PSV) was developed and envelope coreceptor usage, neutralization sensitivity and cross-clade reactivity were characterized. These PSV were neutralized by some antibodies targeting major neutralizing determinants, but potentially important differences were observed in specific sensitivities (eg. to sCD4, MPER and V2/V3 monoclonal antibodies), as well as in properties such as variable loop lengths, number of potential N-linked glycans and charge, demonstrating distinct antigenic characteristics of CRF02_AG and subtype G. There was preferential neutralization of the matched CRF/subtype when PSV from subtype G or CRF02_AG were tested using pooled plasma. These novel Nigerian PSV will be useful to study HIV-1 CRF- or subtype-specific humoral immune responses for subtype G and CRF02_AG.

RESUMEN

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.

RESUMEN

BACKGROUND: Rural African people living with HIV face significant challenges in entering and remaining in HIV care. In rural Uganda, for example, there is a threefold higher prevalence of HIV compared to the national average and lower engagement throughout the HIV continuum of care. There is an urgent need for appropriate interventions to improve entry and retention in HIV care for rural Ugandans with HIV. Though many adults living with HIV in rural areas prioritize seeking care services from traditional healers over formal clinical services, healers have not been integrated into HIV care programs. The Omuyambi trial is investigating the effectiveness of psychosocial support delivered by traditional healers as an adjunct to standard HIV care versus standard clinic-based HIV care alone. Additionally, we are evaluating the implementation process and outcomes, following the Consolidated Framework for Implementation Research. METHODS: This cluster randomized hybrid type 1 effectiveness-implementation trial will be conducted among 44 traditional healers in two districts of southwestern Uganda. Healers were randomized 1:1 into study arms, where healers in the intervention arm will provide 12 months of psychosocial support to adults with unsuppressed HIV viral loads receiving care at their practices. A total of 650 adults with unsuppressed HIV viral loads will be recruited from healer clusters in the Mbarara and Rwampara districts. The primary study outcome is HIV viral load measured at 12 months after enrollment, which will be analyzed by intention-to-treat. Secondary clinical outcome measures include (re)initiation of HIV care, antiretroviral therapy adherence, and retention in care. The implementation outcomes of adoption, fidelity, appropriateness, and acceptability will be evaluated through key informant interviews and structured surveys at baseline, 3, 9, 12, and 24 months. Sustainability will be measured through HIV viral load measurements at 24 months following enrollment. DISCUSSION: The Omuyambi trial is evaluating an approach that could improve HIV outcomes by incorporating previously overlooked community lay supporters into the HIV cascade of care. These findings could provide effectiveness and implementation evidence to guide the development of policies and programs aimed at improving HIV outcomes in rural Uganda and other countries where healers play an essential role in community health. TRIAL REGISTRATION: ClinicalTrials.gov NCT05943548. Registered on July 5, 2023. The current protocol version is 4.0 (September 29, 2023).

RESUMEN

Background: Community Client Led Anti-retroviral therapy Delivery (CCLAD) Model has been associated with increased community participation and ownership, which leads to better treatment outcomes with reduced workload and increased client satisfaction of health services. Aim: To explore the barriers to enrolment of eligible clients into CCLAD in selected health facilities in Kasese District, Uganda. Materials & methods: Analytical cross-sectional study utilizing mixed method approach was conducted among 384 PLWHIV attending public health facilities of Kasese District. Sampling was done by simple random sampling method. Data was collected using researcher-administered questionnaire method and interview guide. Results: Most of the respondents 253(65.9%) had not yet enrolled into CCLAD. This was due to some client-related factors such as non-disclosure of HIV sero-status (p=0.040), person to whom HIV sero-status was disclosed to (p=0.009), not having ever heard about CCLAD (p=0.000), incorrect description of CCLAD (p=0.000), limited knowledge of advantages of CCLAD (p=0.000) or disadvantages of CCLAD (p=0.003). Other barriers were; failure to have access to organizations or groups that support PLWHIV to get treatment (p=0.025) and duration of ART refills [AOR=1.637, 95% CI (0.820 - 3.270)]. Conclusion: Adoption of CCLAD model among PLWHIV in Kasese District is still low.

RESUMEN

HIV infection is one of the most acute problems of our time, characterized by slow development, prolonged course, and numerous clinical manifestations. Currently, there is a large number of drugs acting on different processes of human immunodeficiency virus replication, which constitute the group of highly active antiretroviral therapy (HAART). This article shows a theoretical review of modern HAART and analyzes the prescribed treatment regimens for patients with HIV infection. The study revealed two most common combinations: nucleoside reverse transcriptase inhibitors + protease inhibitors; nucleoside + non-nucleoside reverse transcriptase inhibitors.

RESUMEN

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.

RESUMEN

INTRODUCTION: Assisted partner services (APS), or exposure notification and HIV testing for sexual partners of persons diagnosed HIV positive (index clients), is recommended by the World Health Organization. Most APS literature focuses on outcomes among index clients and their partners. There is little data on the benefits of providing APS to partners of partners diagnosed with HIV. METHODS: We utilized data from a large-scale APS implementation project across 31 facilities in western Kenya from 2018 to 2022. Females testing HIV positive at facilities were offered APS; those who consented provided contact information for all male sexual partners in the last 3 years. Male partners were notified of their potential HIV exposure and offered HIV testing services (HTS). Males newly testing positive were also offered APS and asked to provide contact information for their female partners in the last 3 years. Female partners of male partners (FPPs) were provided exposure notification and HTS. All participants with HIV were followed up at 12 months post-enrolment to assess linkage-to antiretroviral treatment (ART) and viral suppression. We compared HIV positivity, demographics and linkage outcomes among female index clients and FPPs. RESULTS: Overall, 5708 FPPs were elicited from male partners, of whom 4951 received HTS through APS (87% coverage); 291 FPPs newly tested HIV positive (6% yield), an additional 1743 (35.2%) reported a prior HIV diagnosis, of whom 99% were on ART at baseline. At 12 months follow-up, most FPPs were taking ART (92%) with very few adverse events: <1% reported intimate partner violence or reported relationship dissolution. FPPs were more likely than female index clients to report HIV risk behaviours including no condom use at last sex (45% vs. 30%) and multiple partners (38% vs. 19%). CONCLUSIONS: Providing HIV testing via APS to FPP is a safe and effective strategy to identify newly diagnosed females and achieve high linkage and retention to ART and can be an efficient means of identifying HIV cases in the era of declining HIV incidence. The high proportion of FPPs reporting HIV risk behaviours suggests APS may help interrupt community HIV transmission via increased knowledge of HIV status and linkage to treatment.

RESUMEN

INTRODUCTION: Assisted partner services (APS) is an effective strategy for increasing HIV testing, new diagnosis, and linkage to care among sexual partners of people living with HIV (PLWH). APS can be resource intensive as it requires community tracing to locate each partner named and offer them testing. There is limited evidence for the effectiveness of offering HIV self-testing (HIVST) as an option for partner testing within APS. METHODS: We conducted a cluster randomized controlled trial comparing provider-delivered HIV testing (Standard APS) versus offering partners the option of provider-delivered testing or HIVST (APS+HIVST) at 24 health facilities in Western Kenya. Facilities were randomized 1:1 and we conducted intent-to-treat analyses using Poisson generalized linear mixed models to estimate intervention impact on HIV testing, new HIV diagnoses, and linkage to care. All models accounted for clustering at the clinic level and new diagnoses and linkage models were adjusted for individual-level age, sex, and income a priori. RESULTS: From March to December 2021, 755 index clients received APS and named 5054 unique partners. Among these, 1408 partners reporting a prior HIV diagnosis were not eligible for HIV testing and were excluded from analyses. Of the remaining 3646 partners, 96.9% were successfully contacted for APS and tested for HIV: 2111 (97.9%) of 2157 in the APS+HIVST arm and 1422 (95.5%) of 1489 in the Standard APS arm. In the APS+HIVST arm, 84.6% (1785/2111) tested via HIVST and 15.4% (326/2111) received provider-delivered testing. Overall, 16.7% of the 3533 who tested were newly diagnosed with HIV (APS+HIVST = 357/2111 [16.9%]; Standard APS = 232/1422 [16.3%]). Of the 589 partners who were newly diagnosed, 90.7% were linked to care (APS+HIVST = 309/357 [86.6%]; Standard APS = 225/232 [97.0%]). There were no significant differences between the two arms in HIV testing (relative risk [RR]: 1.02, 95% CI: 0.96-1.10), new HIV diagnoses (adjusted RR [aRR]: 1.03, 95% CI: 0.76-1.39) or linkage to care (aRR: 0.88, 95% CI: 0.74-1.06). CONCLUSIONS: There were no differences between APS+HIVST and Standard APS, demonstrating that integrating HIVST into APS continues to be an effective strategy for identifying PLWH by successfully reaching and HIV testing >95% of elicited partners, newly diagnosing with HIV one in six of those tested, >90% of whom were linked to care.

RESUMEN

INTRODUCTION: Improving the delivery of existing evidence-based interventions to prevent and diagnose HIV is key to Ending the HIV Epidemic in the United States. Structural barriers in the access and delivery of related health services require municipal or state-level policy changes; however, suboptimal implementation can be addressed directly through interventions designed to improve the reach, effectiveness, adoption or maintenance of available interventions. Our objective was to estimate the cost-effectiveness and potential epidemiological impact of six real-world implementation interventions designed to address these barriers and increase the scale of delivery of interventions for HIV testing and pre-exposure prophylaxis (PrEP) in three US metropolitan areas. METHODS: We used a dynamic HIV transmission model calibrated to replicate HIV microepidemics in Atlanta, Los Angeles (LA) and Miami. We identified six implementation interventions designed to improve HIV testing uptake ("Academic detailing for HIV testing," "CyBER/testing," "All About Me") and PrEP uptake/persistence ("Project SLIP," "PrEPmate," "PrEP patient navigation"). Our comparator scenario reflected a scale-up of interventions with no additional efforts to mitigate implementation and structural barriers. We accounted for potential heterogeneity in population-level effectiveness across jurisdictions. We sustained implementation interventions over a 10-year period and evaluated HIV acquisitions averted, costs, quality-adjusted life years and incremental cost-effectiveness ratios over a 20-year time horizon (2023-2042). RESULTS: Across jurisdictions, implementation interventions to improve the scale of HIV testing were most cost-effective in Atlanta and LA (CyBER/testing cost-saving and All About Me cost-effective), while interventions for PrEP were most cost-effective in Miami (two of three were cost-saving). We estimated that the most impactful HIV testing intervention, CyBER/testing, was projected to avert 111 (95% credible interval: 110-111), 230 (228-233) and 101 (101-103) acquisitions over 20 years in Atlanta, LA and Miami, respectively. The most impactful implementation intervention to improve PrEP engagement, PrEPmate, averted an estimated 936 (929-943), 860 (853-867) and 2152 (2127-2178) acquisitions over 20 years, in Atlanta, LA and Miami, respectively. CONCLUSIONS: Our results highlight the potential impact of interventions to enhance the implementation of existing evidence-based interventions for the prevention and diagnosis of HIV.

RESUMEN

INTRODUCTION: In Belgium, oral HIV pre-exposure prophylaxis (PrEP) is primarily provided in specialized clinical settings. Optimal implementation of PrEP services can help to substantially reduce HIV transmission. However, insights into implementation processes, and their complex interactions with local context, are limited. This study examined factors that influence providers' adaptive responses in the implementation of PrEP services in Belgian HIV clinics. METHODS: We conducted a qualitative multiple case study on PrEP care implementation in eight HIV clinics. Thirty-six semi-structured interviews were conducted between January 2021 and May 2022 with a purposive sample of PrEP care providers (e.g. physicians, nurses, psychologists), supplemented by 50 hours of observations of healthcare settings and clinical interactions. Field notes from observations and verbatim interview transcripts were thematically analysed guided by a refined iteration of extended Normalisation Process Theory. RESULTS: Implementing PrEP care in a centralized service delivery system required considerable adaptive capacity of providers to balance the increasing workload with an adequate response to PrEP users' individual care needs. As a result, clinic structures were re-organized to allow for more efficient PrEP care processes, compatible with other clinic-level priorities. Providers adapted clinical and policy norms on PrEP care (e.g. related to PrEP prescribing practices and which providers can deliver PrEP services), to flexibly tailor care to individual clients' situations. Interprofessional relationships were reconfigured in line with organizational and clinical adaptations; these included task-shifting from physicians to nurses, leading them to become increasingly trained and specialized in PrEP care. As nurse involvement grew, they adopted a crucial role in responding to PrEP users' non-medical needs (e.g. providing psychosocial support). Moreover, clinicians' growing collaboration with sexologists and psychologists, and interactions with PrEP users' family physician, became crucial in addressing complex psychosocial needs of PrEP clients, while also alleviating the burden of care on busy HIV clinics. CONCLUSIONS: Our study in Belgian HIV clinics reveals that the implementation of PrEP care presents a complex-multifaceted-undertaking that requires substantial adaptive work to ensure seamless integration within existing health services. To optimize integration in different settings, policies and guidelines governing PrEP care implementation should allow for sufficient flexibility and tailoring according to respective local health systems.

RESUMEN

INTRODUCTION: Approval of the first long-acting injectable antiretroviral therapy (LAI ART) medication heralded a new era of HIV treatment. However, the years since approval have been marked by implementation challenges. The "Accelerating Implementation of Multilevel Strategies to Advance Long-Acting Injectable for Underserved Populations (ALAI UP Project)" aims to accelerate the systematic and equitable delivery of LAI ART. METHODS: We coded and analysed implementation barriers according to the Consolidated Framework for Implementation Research (CFIR) domains, desired resources and programme goals from questionnaire short-answer responses by clinics across the United States responding to ALAI UP's solicitation to participate in the project between November 2022 and January 2023. RESULTS: Thirty-eight clinics responded to ALAI UP's solicitation. The characteristics of LAI ART as an innovation (cost, complexity of procurement, dosing interval, limited eligibility) precipitated and interacted with barriers in other CFIR domains. Barriers included obtaining coverage for the cost of medication (27/38 clinics) (outer setting); need for new workflows and staffing (12/38) and/or systems to support injection scheduling/coordination (16/38), transportation and expanded clinic hours (13/38) (inner setting); and patient (10/38) and provider (7/38) education (individuals). To support implementation, applicants sought: technical assistance to develop protocols and workflows (18/38), specifically strategies to address payor challenges (8/38); additional staff for care coordination and benefits navigation (17/38); opportunities to share experiences with other implementing clinics (12/38); patient-facing materials to educate and increase demand (7/38); and support engaging communities (6/38). Clinics' LAI ART programme goals varied. Most prioritized delivering LAI ART to their most marginalized patients struggling to achieve viral suppression on oral therapy, despite awareness that current US Food and Drug Administration approval is only for virally suppressed patients. The goal for LAI ART reach after 1 year of implementation ranged from ≤10% of patients with HIV on LAI ART (17/38) to ≥50% of patients (2/38). CONCLUSIONS: Diverse clinic types are interested in offering LAI ART and most aspire to use LAI ART to support their most vulnerable patients sustain viral suppression. Dedicated resources centred on equity and relevant to context and population are needed to support implementation. Otherwise, the introduction of LAI ART risks exacerbating, not ameliorating, health disparities.

RESUMEN

BACKGROUND: Acquired syphilis continues to affect millions of people around the world. It is crucial to study it in the context of HIV Pre-Exposure Prophylaxis (PrEP) to achieve the goals set out in the 2030 Agenda since the literature suggests increased risk behaviors for sexually transmitted infections. This study aimed to investigate the incidence and factors associated with acquired syphilis among PrEP users. MATERIALS AND METHODS: This retrospective cohort included data on PrEP users from all over Brazil from 2018 to 2020, retrieved from the national antiretroviral logistics system. We calculated the proportion of syphilis before PrEP, the incidence during the user's follow-up, reinfections, and their possible associated factors. We conducted descriptive, bivariate, and multivariate analysis, estimating the crude Relative Risk, adjusted Odds Ratio (aOR), and their respective confidence intervals (95%CI). RESULTS: Most of the 34,000 individuals who started PrEP were male (89.0%), white (53.7%), self-identified as male (85.2%), homosexual, gay, or lesbian (72.2%), and had 12 schooling years or more (67.8%). Of these, 8.3% had syphilis in the six months before starting PrEP, and 4% had it in the first 30 days of using the prophylaxis. We identified a loss-to-follow-up rate of 41.7%, although the loss and the cohort shared similar characteristics. The proportion of missed syphilis tests was high: 33.4% in the 30 days and 38.8% in the follow-up period. In the 19,820 individuals effectively monitored, the incidence of acquired syphilis was 19.1 cases per 100 person-years, and 1.9% of users had reinfection. The rate of missed syphilis tests at the 30-day follow-up was 33.4%, and the total follow-up test period was 38.8%. The multivariate analysis identified female gender (aOR 0.3; 95%CI 0.2-0.5), being white or Black (aOR 0.9; 95%CI 0.7-0.9 and aOR 0.7; 95%CI 0.7-0.99, respectively) as protective factors for syphilis. Being homosexual, gay, lesbian (aOR 2.7; 95%CI 2.0-3.7), or having a history of syphilis in the six months before PrEP (aOR 2.2; 95%CI 1.9-2.5) were risk factors for syphilis during PrEP use. Behaviors related to the risk of syphilis included accepting something in exchange for sex (aOR 1.6; 95%CI 1.3-1.9), irregular condom use (use in less than half of sexual intercourse sessions; aOR 1.7; 95%CI 1.53-2.1) and recreational drug use (poppers; aOR 1.5; 95%CI 1.53-2.1). CONCLUSION: Syphilis in the context of PrEP has high rates and is associated with sociodemographic and behavioral factors. We recommend additional studies targeting prevention in this population to curb these figures.

RESUMEN

Antiretroviral therapy, also known as antiretroviral therapy (ART), has been at the forefront of the ongoing battle against human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDs). ART is effective, but it has drawbacks such as side effects, medication resistance, and difficulty getting access to treatment, which highlights the urgent need for novel treatment approaches. This review explores the complex field of HIV/AIDS treatment, covering both established alternative treatment modalities and orthodox antiretroviral therapy. Numerous reliable databases were reviewed, including PubMed, Web of Science, Scopus, and Google Scholar. The results of a thorough literature search revealed numerous therapeutic options, including stem cell transplantation, immunotherapy, gene therapy, latency reversal agents, and pharmaceutical vaccinations. While gene therapy has promise for altering cellular resistance to infection and targeting HIV-positive cells, immunotherapy treatments seek to strengthen the immune system's ability to combat HIV. Latency reversal agents offer a promising method of breaking the viral latency and making infected cells vulnerable to immune system destruction or antiretroviral drugs. Furthermore, there is potential for improving immune responses against HIV using medical vaccinations. This review stresses the vital significance of ongoing research and innovation in the hunt for a successful HIV/AIDS treatment through a thorough examination of recent developments and lingering challenges. The assessment notes that even though there has been tremendous progress in treating the illness, there is still more work to be done in addressing current barriers and investigating various treatment options in order to achieve the ultimate objective of putting an end to the HIV/AIDS pandemic.
