BACKGROUND: Darunavir/cobicistat/emtricitabine/tenofovir alafenamide (D/C/F/TAF) fixed-dose combination (FDC) was developed as a once-daily, complete antiretroviral (ARV) regimen therapy to address the need for simplified protease inhibitor-based ARV regimens. This study assessed the swallowability and acceptability for long-term use of scored placebo tablets matching the D/C/F/TAF FDC tablets in children living with HIV-1. METHODS: This study (NCT04006704) was a Phase 1, open-label, randomized, single-dose, 2-period, 2-sequence crossover study in children living with HIV-1, aged ≥6 to <12 years and weighing ≥25 to <40 kg, on a stable ARV regimen for ≥3 months. Participants were asked to swallow whole (size, 21 × 11 × 7 mm) and split matching placebo D/C/F/TAF tablets. Swallowability of the matching placebo D/C/F/TAF tablets (primary endpoint) was assessed by observers. Acceptability of taking matching placebo D/C/F/TAF tablets and current ARVs was evaluated by participants using a 3-point questionnaire. Participants rated the acceptability for long-term daily use of the placebo D/C/F/TAF tablets, and observers assessed how easily caregivers could split a scored tablet by hand, using 3-point questionnaires. RESULTS: Among the 24 participants who enrolled and completed the study, 95.8% (23/24) were able to swallow the whole and split matching placebo D/C/F/TAF tablets after 1 or 2 attempts. Most participants (>70%) rated the acceptability of tablets for long-term daily use as acceptable or good to take. Breaking the tablets was considered easy or OK by 79.2% (19/24) of caregivers. CONCLUSION: Scored D/C/F/TAF FDC tablets are swallowable - with whole favoured over split - and considered at least acceptable for long-term daily intake in children living with HIV-1 aged ≥6 to <12 years. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04006704.

BACKGROUND: Recently, injectable cabotegravir/rilpivirine (ICAB/RPV) became available for HIV treatment. However, there are no real-life data on the impact of switching to ICAB/RPV on sleep disturbances (SD). Therefore, we aimed at assessing and investigating this aspect in our cohort. METHODS: A SD multidimensional assessment (Epworth Sleepiness scale, Insomnia severity Index, Berlin Questionnaire, and Pittsburg Sleep Quality Index, PSQI) was performed to all people who consented before starting ICAB/RPV and 12 wk after the switch. Demographics, life-style habits, laboratory, and clinical data were collected from medical health records. RESULTS: To June 2023, 46 people were included, 76.1% males, with a median age of 48.5 (IQR: 41-57), 50% had multimorbidity, 13% was on polypharmacy. Median age with HIV and CD4 + T cell count nadir were 10 (5-19.5) years and 360 (205-500) cell/mm3, respectively. The reason to start a long-acting strategy was person's choice in all cases. Baseline antiretroviral regimens were mostly: tenofovir alafenamide/emtricitabine/rilpivirine (39.1%) and dolutegravir/lamivudine (32.6%). No significant changes were observed in any of the scores for each questionnaire, but for a worsening PSQI. 37% people reported a subjectively improved sleep quality, even if statistically significant changes were not observed in almost all the sleep parameters. CONCLUSIONS: To the best of our knowledge, this is the first study exploring impact of switching to ICAB/RPV on SD. Despite integrase inhibitor have been associated with SD, we did not observed a negative impact on sleep quality after the switch to ICAB/RPV. More studies and with larger number of people are necessary to confirm our results.

BACKGROUND: The approval of long-acting pre-exposure prophylaxis PrEP (LA-PrEP) in the United States brings opportunities to overcome barriers of oral PrEP, particularly among sexual and gender minority communities who bear a higher HIV burden. Little is known about real-time decision-making among potential PrEP users of LA-PrEP post-licensure. METHODS: We held focus group discussions with people assigned male at birth who have sex with men in Baltimore, Maryland to explore decision-making, values, and priorities surrounding PrEP usage. A sexual and gender minority-affirming health center that provides PrEP services supported recruitment. Discussions included a pile-sorting activity and were audio-recorded. Recordings were transcribed and analyzed iteratively, combining an inductive and deductive approach. RESULTS: We held five focus groups from Jan-June 2023 with 23 participants (21 cisgender men who have sex with men, two transgender women who have sex with men; mean age 37). Among participants, 21 were on oral PrEP, one was on injectable PrEP, and one had never taken PrEP. Most had never heard about LA-PrEP. When making decisions about PrEP, participants particularly valued efficacy in preventing HIV, side effects, feeling a sense of security, and ease of use. Perceptions varied between whether oral or injectable PrEP was more convenient, but participants valued the new opportunity for a choice in modality. Factors influencing PrEP access included cost, individual awareness, provider awareness, and level of comfort in a healthcare environment. Participants emphasized how few providers are informed about PrEP, placing the burden of being informed about PrEP on them. Comfort and trust in a provider superseded proximity as considerations for if and where to access PrEP. CONCLUSIONS: There is still low awareness about LA-PrEP among sexual and gender minority communities; thus, healthcare providers have a critical role in influencing access to LA-PrEP. Despite this, providers are still vastly underinformed about PrEP and underprepared to support clients in contextualized ways. Clients are more likely to engage in care with affirming providers who offer non-judgmental conversations about sex and life experiences. Provider education in the United States is urgently needed to better support clients in choosing a PrEP modality that is right for them and supporting adherence for effective HIV prevention.

Pre-exposure prophylaxis (PrEP) decreases the risk for HIV transmission in high-risk populations. PrEP has been available in Denmark since 2019 and consists of antiretroviral drugs in a combination tablet taken daily or on demand. The effect of this prophylaxis in Denmark is summarized in the review. PrEP is indicated in men and transgender persons with unprotected anal intercourse with multiple male partners in the latest 12 weeks or recent diagnoses of syphilis, chlamydia, or gonorrhoea. PrEP is provided by infectious disease specialists. Continued implementation could significantly reduce HIV transmission and potentially end the epidemic in Denmark.

The efficacy of 400mg efavirenz (EFV) once daily is reported to be similar to that of 600mg EFV. However, EFV-related toxic and side effects of 400mg EFV are significantly reduced. Here, the feasibility of reducing EFV to 400mg once a day in HIV-infected/AIDS patients was evaluated. Fifty patients were included. Patients were given 3TC+TDF+400mg EFV (n=25) or 3TC+TDF+600mg EFV (n=25). The proportion of patients with HIV RNA < 40 copies/mL and the adverse events served as the primary and secondary outcomes, respectively. HIV inhibition rates of the 3TC+TDF+400mg EFV group and 3TC+TDF+600mg EFV group were both 56.52% at week 24 and respectively 100%, 91.3% at week 48. During 48 weeks, 27 cases of adverse events were reported in the 3TC+TDF+400mg EFV group, lower than those in the 3TC+TDF+600mg EFV group, which had 39 cases. Compared with the 3TC+TDF+400mg EFV group, the incidence of transaminase, dizziness, hyperlipidemia and rashes all increased in the 3TC+TDF+600mg EFV group (P>0.05). No serious adverse events of the central nervous system occurred. The incidence of depression, sleep disturbance, and vertigo were similar (P>0.05). The efficacy of 400mg EFV is comparable to 600mg EFV. However, patients receiving 400mg EFV have fewer adverse events.

INTRODUCTION: Some African countries plan to introduce and scale-up new long-acting pre-exposure prophylaxis methods (LA-PrEP), like the monthly dapivirine vaginal ring (PrEP ring) and injectable cabotegravir. National costed implementation plans, roadmaps for successful product implementation, are often overlooked. International stakeholders engaged in oral PrEP planning, introduction and scale-up are an information resource of lessons learned to advise LA-PrEP planning. We consulted such international stakeholders and synthesised oral PrEP lessons to inform the development of a costed rollout plan template for LA-PrEP. METHODS: From selected global health organisations (five international nongovernmental, four donor, four university/research and two multilateral), we interviewed 27 representatives based in America, Europe, Asia and Africa about strategic content and approaches for LA-PrEP policy, programming and implementation. We conducted a thematic analysis of the interview data for implementation considerations. RESULTS: From the consultations, we identified six implementation themes for LA-PrEP introduction and scale-up: (1) ethically increasing choice and avoiding coercion; (2) de-stigmatising PrEP by focusing on preference rather than risk-based eligibility; (3) integrating LA-PrEP into services that are more woman-oriented, couple-oriented and family-oriented, and providing private spaces for LA-PrEP delivery; (4) de-medicalising delivery of relatively safe products (eg, PrEP ring); (5) constructing multilevel, nuanced communication strategies to address measured and perceived product efficacy and effectiveness; and (6) devising product-agnostic, modular approaches to service delivery. Despite the widespread emphasis on integration, few stakeholders offered empirical examples of successful integration approaches and frameworks. CONCLUSIONS: Lessons learnt from stakeholder participants suggest standardised and modular processes can improve efficiencies in LA-PrEP planning and implementation. Tiered communication strategies addressing product efficacy and effectiveness will improve clients' and providers' efficacy in making informed decisions. Integration is important for LA-PrEP delivery, but data on empirical integration approaches and frameworks is minimal: further research in this discipline is needed.

OBJECTIVES: We aimed to develop a guidance on the use of pre-exposure prophylaxis (PrEP) for HIV tailored to the Belgian context. METHODS: Different aspects of PrEP care were judged by an expert group of nine Belgian clinicians, seeking consensus for areas of controversies. RESULTS: PrEP should be considered in HIV negative patients at high risk of acquiring HIV. Currently, only oral tenofovir/emtricitabine is available in Belgium for PrEP, which can be used daily, or also event-driven in cisgender men and trans women who are not taking exogenous estradiol-based hormones. Personal counselling directed at medication adherence and sexual health should have a central role in PrEP care. At the initial assessment clinicians should give attention to symptoms of an acute HIV infection, the patients' immunization status and renal function. A regular follow-up must be set up to diagnose HIV seroconversion, treat sexually transmitted infections, and manage side effects of PrEP. CONCLUSION: The Belgian guidance on the use of PrEP provides a point of reference for standard PrEP care in Belgium and will be periodically updated.

GSK2838232 (GSK8232) is a second-generation maturation inhibitor (MI) developed for the treatment of HIV with excellent broad-spectrum virological profiles. The compound has demonstrated promising clinical results as an orally administered agent. Additionally, the compound's physical and pharmacological properties present opportunities for exploitation as long-acting parenteral formulations. Despite unique design constraints including solubility and dose of GSK8232, we report on three effective tunable drug delivery strategies: active pharmaceutical ingredient (API) suspensions, ionic liquids, and subdermal implants. Promising sustained drug release profiles were achieved in rats with each approach. Additionally, we were able to tune drug release rates through a combination of passive and active strategies, broadening applicability of these formulation approaches beyond GSK8232. Taken together, this report is an important first step to advance long-acting formulation development for critical HIV medicines that do not fit the traditional profile of suitable long-acting candidates.

Lamivudine (3TC)/dolutegravir (DTG) single tablet regimen (STR) has shown long-term efficacy and tolerability in people living with HIV (PLWH). Dolutegravir has been approved for use in children, while data on the efficacy of 3TC plus DTG in maintaining virological suppression in this population are still under evaluation. In this case series, we describe three children with perinatally acquired HIV who maintained virological suppression after switching antiretroviral therapy to DTG/3TC. We present three case reports of three children enrolled in the Italian Register for HIV Infection in Children: a 9-year-old boy, a 10-year-old girl, and a 2-year-old girl with perinatally acquired HIV who immediately started antiretroviral therapy with a three-drug regimen upon diagnosis, which occurred at delivery, after 6 months of life, and after 2 years of life, respectively. They achieved and maintain virological suppression after 1, 6, and 7 months of therapy, respectively; then a switch strategy was performed with a two-drug regimen with DTG/3TC STR at the age of 7 years for the first child and at the age of 9 years for the second, while the third was switched to a DTG plus 3TC not STR, owing to weight requirements, at the age of 2 years and 10 months. All children maintained virological suppression at last follow-up visit (January 2024), showing an excellent growth curve and maintaining good adherence and tolerability to DTG plus 3TC. A two-drug regimen with DTG/3TC demonstrated efficacy in maintaining virological suppression in a switch strategy in these children, with important advantages such as better tolerability and comfort of taking a single tablet once daily.

BACKGROUND: As oral PrEP scales up in Nigeria, information about uptake, use pattern and client preference in a real-world, implementation setting is invaluable to guide refining service provision and incorporation of oral PrEP and other prevention measures into routine health services. To add to this body of knowledge, our study examines factors associated with discontinuation of PrEP among HIV negative individuals across two large scale programs in Nigeria. METHODS: Using program implementation data from two large-scale HIV projects in Akwa Ibom and Cross River states in Nigeria between January 2020 and July 2021, we used logistic regression to explore factors associated with early discontinuation (i.e., stopping PrEP within one month of starting) among HIV-negative individuals who initiated PrEP in the programs. RESULTS: Of a total of 26,325 clients; 22,034 (84%) discontinued PrEP within the first month. The odds of PrEP discontinuation were higher among clients who enrolled in community-based distribution sites (aOR 2.72; 95% C.I: 2.50-2.96) compared to those who enrolled in program-supported facilities and never married (aOR 1.76; 95% C.I: 1.61-1.92) compared to married clients. Clients who initiated PrEP because of high-risk sexual behaviour (aOR 1.15, 95% C.I 1.03-1.30) or inconsistent use or non-use of condoms (aOR 1.96, 95% C.I 1.60-2.41) had greater odds of discontinuing PrEPthan those who initiated PrEP because they were in a serodifferent relationship. CONCLUSION: The behavioural and demographic factors associated with early discontinuation of PrEP suggest that risk stratification of pre-initiation and follow up counselling may be helpful in raising continuation rates. On the service delivery side, strategies to strengthen follow-up services provided by community-based distribution sites need to be introduced. Overall, the low continuation rate calls for a review of programmatic approaches in provision of PrEP services in Nigeria.

INTRODUCTION: HIV pre-exposure prophylaxis (PrEP) is effective at reducing HIV transmission. However, PrEP uptake is low for racial and ethnic minorities and women, especially in the Southern US Health care clinicians should be prepared to identify all patients eligible for PrEP, provide counseling, and prescribe PrEP. METHODS: Retrospective analysis of persons newly diagnosed with HIV was conducted at a large public health system from January 2015 to June 2021. Interactions with the health system in the 5 years preceding HIV diagnosis were analyzed, and missed opportunities for HIV prevention interventions, including PrEP and condom use counseling, were identified. RESULTS: We identified 454 patients with a new HIV diagnosis with previous health system interactions. 166(36.6%) had at least 1 identifiable indication for PrEP: 42(9.3%) bacterial STI, 63(13.9%) inconsistent condom use, or 82(18%) injection drug use before HIV diagnosis. Only 7(1.5%) of patients were counseled on PrEP. Most patients (308; 67.8%) had no documented condom use history in the EHR before diagnosis, a surrogate marker for obtaining a sexual history. Patients who exclusively interacted with the emergency care setting did not receive PrEP education and were less likely to receive condom use counseling. CONCLUSION: Missed opportunities to offer HIV prevention before diagnosis were common among patients newly diagnosed with HIV. Most patients did not have sexual history documented in the chart before their HIV diagnosis. Educational interventions are needed to ensure that clinicians are prepared to identify those eligible and discuss the benefits of PrEP.

PURPOSE: To evaluate the real-world rates of non-adherence and non-persistence to antiretroviral therapy (ART) among treatment-naïve adult patients with HIV after a 12-month follow-up period in Belgium. METHODS: A retrospective analysis of longitudinal pharmacy claims was conducted using the Pharmanet database from January 1, 2018, to December 31, 2021. Non-adherence was assessed over 12 months and reported as the proportion of days covered below the 80% threshold. Non-persistence was defined as the first 90-day gap in treatment between the two types of ART dispensed. Poisson regression with robust standard error and Cox proportional hazard models were used to assess the factors associated with non-adherence and non-persistence, respectively. RESULTS: Overall, 2999 patients were initiated on ART between 2018 and 2021. After a 12-month follow-up, the proportions of non-adherence and non-persistence were 35.6% and 15.9%, respectively in 2018, and decreased to 18.7% and 6.8%, respectively in 2021. Non-adherence was higher among women, Brussels residents, and those receiving multiple-tablet regimens (MTRs). Similarly, the prevalence of non-persistence was higher among women and MTR recipients. CONCLUSION: Among treatment-naïve adults with HIV in Belgium, non-adherence, and non-persistence to ART showed improvement over the study period but remained at high levels. Disparities were observed by sex and between geographical regions. Prioritizing strategies targeting women in Brussels and facilitating the transition from MTRs to single-tablet regimens should be emphasized optimize adherence to ART in Belgium.

BACKGROUND: Carbamazepine (CBZ) is an antiseizure medication known to induce the expression of cytochrome P4503A metabolic enzymes. Here, we describe a man living with HIV who underwent several changes in the daily dose of CBZ, which resulted in different induction effects on darunavir trough concentrations. METHODS: A 59-year-old man with HIV, successfully undergoing maintenance antiretroviral treatment with darunavir/cobicistat once daily (combined with raltegravir), was prescribed CBZ for recurrent trigeminal neuralgia. Over subsequent months, the patient underwent various changes in the doses (from 200 to 800 mg/d) and trough concentrations (from 3.6 to 18.0 mg/L) of CBZ, guided by clinical response to trigeminal neuralgia. RESULTS: A highly significant inverse association was observed between darunavir trough concentration and both CBZ dose or trough concentration (coefficient of determination >0.75, P < 0.0001). Ultimately, the darunavir dose was increased to 600 mg twice daily with ritonavir and dolutegravir to ensure optimal antiretroviral coverage, anticipating potential further uptitration of CBZ doses. CONCLUSIONS: The impact of CBZ on boosted darunavir exposure seemed to be dose- and concentration-dependent. The management of such drug-drug interactions in daily practice was facilitated through therapeutic drug monitoring. This case underscores the importance of a multidisciplinary approach that incorporates both antiretroviral and nonantiretroviral comedications contributing to the optimal management of polypharmacy in individuals living with HIV.

INTRODUCTION: Adolescent girls and young women (AGYW), a priority population for HIV prevention in Africa, show high interest but difficulty in sustained effective use of pre-exposure prophylaxis (PrEP). With ongoing PrEP scale-up focused on increasing access, it is important to understand what influences AGYW's choice of PrEP delivery platforms. METHODS: The POWER implementation study in Cape Town provided PrEP between 2017 and 2020 to AGYW (16-25 years) from four differentiated delivery platforms: mobile clinic, government facility, courier delivery or community-based youth club. Healthcare providers at government and mobile clinics provided PrEP (initiation and refills) as part of comprehensive, integrated sexual and reproductive health services. Courier and youth club platforms provided light-touch PrEP refill services incorporating rapid HIV self-testing. We conducted in-depth interviews with a purposive sample of AGYW who had ≥3 months of PrEP-use and accessed ≥2 PrEP delivery platforms. The thematic analysis explored AGYW's preferences, decision-making and habits related to PrEP access to inform market segmentation. RESULTS: We interviewed 26 AGYW (median age 20) PrEP-users between November 2020 and March 2021. AGYW PrEP-users reported accessing different services with, 24 accessing mobile clinics, 17 courier delivery, 9 government health facilities and 6 youth clubs for their PrEP refills. Qualitative findings highlighted four potential behavioural profiles. The "Social PrEP-user" preferred PrEP delivery in peer spaces, such as youth clubs or adolescent-friendly mobile clinics, seeking affirmation and social support for continued PrEP use. The "Convenient PrEP-user" favoured PrEP delivery at easily accessible locations, providing quick (courier) or integrated contraception-PrEP refill visits (mobile and government clinic). The "Independent PrEP-user" preferred PrEP delivery that offered control over delivery times that fit into their schedule, such as the courier service. The "Discreet PrEP-user" highly valued privacy regarding their PrEP use (courier delivery) and avoided delivery options where unintentional disclosure was evident (youth club). Comfort with HIV self-testing had minimal influence on PrEP delivery choice. CONCLUSIONS: Market segmentation of AGYW characterizes different types of PrEP-users and has the potential to enhance tailored messaging and campaigns to reach specific segments, with the aim of improving sustained PrEP use and HIV prevention benefits.

INTRODUCTION: South African men face a substantial burden of HIV and are less likely to test for HIV and initiate antiretroviral therapy if tested positive and more likely to die from AIDS-related causes than women. In addition to condoms and circumcision, guidelines provide for the use of daily oral pre-exposure prophylaxis (PrEP) as an HIV prevention intervention for any men who recognize their need and request PrEP. However, heterosexual men have not been a focus of PrEP programmes, and since its introduction, there is limited literature on PrEP use among men in South Africa. This study explores the experiences, motivators and barriers to oral PrEP use among heterosexual men accessing primary healthcare services in South Africa. METHODS: This study forms part of a mixed-methods implementation science study aimed at generating evidence for oral PrEP introduction and conducted in primary healthcare clinics in South Africa since 2018. Men aged ≥15 years who initiated oral PrEP and enrolled in a parent cohort study were purposefully invited to participate in an in-depth interview (IDI). Between March 2020 and May 2022, 30 men participated in IDIs exploring their motivators for PrEP use, and experiences with accessing health services. Interviews were audio recorded, transcribed and analysed thematically. RESULTS: The final analysis included 28 heterosexual men (18-56 years old). Motivations to initiate PrEP included fear of acquiring HIV, self-perceived vulnerability to HIV and mistrust in relationships; health systems factors which motivated PrEP use included the influence of healthcare providers, educational materials and mobile services. Perceived reduction in HIV vulnerability and changing proximity to partners were reasons for PrEP discontinuation. Side effects, daily-pill burden and stigma were noted as challenges to PrEP use. Health system barriers to PrEP use included limited PrEP availability, school and work demands, and inconsistent mobile clinic schedules. CONCLUSIONS: Our study reports on the experiences of heterosexual men accessing oral PrEP in real-world settings and contributes to the limited literature among this population. We highlight multiple levels which could be strengthened to improve men's PrEP use, including individual support, education among partners and communities, and addressing health system barriers to access.

INTRODUCTION: HPTN 083 demonstrated the superiority of long-acting cabotegravir (CAB-LA) versus daily oral emtricitabine/tenofovir disoproxil fumarate (TDF/FTC) as pre-exposure prophylaxis (PrEP) among cisgender men and transgender women who have sex with men (MSM/TGW). HPTN 083 provided the first opportunity to understand experiences with injectable PrEP in a clinical trial. METHODS: Participants from two US sites (Chicago, IL and Atlanta, GA) and one international site (Rio de Janeiro, Brazil) were purposively sampled for individual qualitative interviews (N = 40), between November 2019 and March 2020, to explore trial experiences, barriers to adherence and other factors that may have impacted study implementation or outcomes. The blinded phase ended early due to efficacy; this analysis includes interviews conducted prior to unblinding with three groups defined by adherence (i.e. injection visit attendance): adherent (n = 27), non-adherent (n = 12) and early discontinuers (n = 1). Data were organized using NVivo software and analysed using content analysis. RESULTS: Participants (mean age: 27) were primarily cisgender MSM (90%) and Black/African American (60%). Reasons for trial enrolment and PrEP use included a preference for using HIV prevention medication versus treatment in the event of HIV acquisition; the ability to enhance health via study-related education and services; access to a novel, convenient HIV prevention product at no cost; and contributing to MSM/TGW communities through research. Participants contrasted positive experiences with study staff with their routine clinical care, and emphasized increased scheduling flexibility, thorough communication, non-judgemental counselling and open, affirming environments (e.g. compassion, less stigma) as adherence facilitators. Injection experiences were positive overall; some described early injection-related anxiety, which abated with time and when given some measure of control (e.g. pre-injection countdown), and minimal injection site discomfort. Some concerns and misperceptions about injectable PrEP were reported. Barriers to adherence, across all adherence categories, included structural factors (e.g. financial constraints, travel) and competing demands (e.g. work schedules). CONCLUSIONS: Respondents viewed injectable PrEP trial participation as a positive experience and a means of enhancing wellbeing. Study site flexibility and affirming clinic environments, inclusive of non-judgemental counselling, were key facilitators of adherence. To support injection persistence, interventions that address structural barriers and promote flexible means of injection delivery may be most effective.

Introduction: virological non-suppression is not only associated with increased risk of transmission of the Human Immunodeficiency virus (HIV) to others; perinatally and sexually, but it also decreases the life expectancy among the individuals who are on antiretroviral therapy (ART). This study sought to determine the level of virological non-suppression among ART patients from selected health facilities of a sub-district in uMgungundlovu district. This sub-district has high HIV transmission rates in KwaZulu Natal (KZN) and had one of the highest HIV prevalence in the district in 2018; population weighted HIV prevalence of 36.3% among men and women aged 15-49 years old, which was twice the average national prevalence of 18.8%. Methods: this descriptive, cross-sectional, and quantitative study was conducted among participants who were HIV-positive, 18 years old and above, and initiated on ART between January 2017 and January 2019 at selected PHC facilities of Vulindlela sub district. Health facility treatment registers, patient medical files and face-to-face interviews were used to collect the data and these were captured onto an Excel spreadsheet, cleaned, coded before importation into Epiinfo 17 for statistical analyses. Logistic regression analyses were conducted to investigate the factors associated with virological non-suppression. Results: the study found a majority of participants were females (240/401 (60%)). The mean age of the participants was 38.1 (SD=11.2), with most participants who were between the ages of 29 and 39 years old (167 (41.7%)). Virological non-suppression was observed among 10% (40/401) of participants. The odds of virological non-suppression were higher among participants who were married (aOR 4.76, 95% CI 1.49-15.19; p=0.008). Conclusion: a virological non-suppression of 10% translates to viral suppression of 90%, which is below the target of UNAIDS 95-95-95 strategy. Hiding and skipping medication indicate how non-disclosure continues to hinder HIV treatment adherence. High odds of virological non-suppression among married participants indicate non-disclosure of the positive HIV status, or lack in spousal support.

BACKGROUND: For those HIV seropositive people with high viral loads, the World Health Organization recommends more counseling before changing ART regimens. A high viral load can lead to increased HIV transmission and lower survival rates. Clients with viral loads above 1000 copies/mL should receive enhanced adherence counseling for 3-6 months before switching. Despite enhanced adherence counseling programs, most countries struggle with viral load suppression. Little is known about viral load suppression in Ethiopia and the research area after counseling. OBJECTIVE: This study aims to assess viral load suppression and its predictors among HIV-positive individuals receiving enhanced adherence counseling in Bahir Dar, Northwest Ethiopia, in 2022. METHODS: An institution-based retrospective follow-up study was conducted among randomly selected 546 clients on Enhanced Adherence Counseling at public health facilities in Bahir Dar city. The Epicollect5 mobile application was used to collect the data, which was then exported to Stata version 14 for analysis. A Log-Binomial regression model was fitted for each explanatory variable. Variables having a p-value <0.25 in bivariate analysis were entered into a multivariable Log-Binomial regression model. Finally, an adjusted risk ratio with a 95% confidence interval and a p-value <0.05 was used to measure the strength of the prediction. RESULTS: Following enhanced adherence counseling, 312 (57.1%) people had their viral load suppressed. Absence of recurrent OI (ARR 1.40; CI 1.03-1.91), EAC stay less than 3 months (ARR 1.54; CI 1.19-1.99), EAC stay 3-6 months (ARR 1.38; CI 1.12-1.69), once-daily ARV dose regimen (ARR 1.28; CI 1.03-1.58), baseline viral load of 2879.00 copies/ml (ARR 1.30, CI 1.06-1.60), being orthodox Tewahido Christian (ARR 0.37; CI 0.18-0.75) were significant predictors of viral load suppression after Enhanced Adherence Counseling. CONCLUSION AND RECOMMENDATION: Most importantly, this study found that most people had suppressed viral loads after receiving enhanced adherence counseling. Significant predictors of viral load suppression included recurrent OI, length of stay on EAC, daily ARV dosing regimen, baseline viral load, and religion. Clients with a high baseline viral load and those who experience recurring opportunistic infections should get extra care during EAC sessions.
