Positive STEPS: Enhancing Medication Adherence and Achieving Viral Load Suppression in Youth Living with HIV in the United States - Results from a Stepped-Care Randomized Controlled Efficacy Trial.

In the U.S. and worldwide, there is a significant number of young people acquiring and living with HIV. Antiretroviral therapy (ART) has led to significant reductions in HIV-related illnesses and deaths, allowing young people living with HIV to manage their condition as a chronic disease. Ensuring high levels of ART adherence is vital for treatment success. Despite this, to the best of our knowledge, there are no efficacious behavioral interventions for improving ART adherence and viral suppression among youth in the U.S. We conducted a multicity, randomized controlled trial-in Boston, MA Providence, RI and Chicago, IL- to examine the efficacy of an stepped-care, behavioral and technology-based intervention, "Positive STEPS," compared to a standard of care (SOC) control, for improving ART adherence and viral suppression among youth living with HIV ages 16 to 29 years. Positive STEPS included: Step-1: TXTXT, an evidence-based, daily two-way personalized text message reminder to take ART medications; and Step-2: only participants with <90% adherence anytime between weeks 5 and 12 post-randomization to the Positive STEPS arm, would then receive five 50-minute sessions of manualized individual adherence counseling. If their adherence remained at 90% or higher, then they did not progress to Step-2. Adherence was measured via Wisepill, an electronic medication monitoring device, and self-report. Participants were followed for 12-months and completed biospecimen collection (HIV plasma RNA viral load testing) and a quantitative assessment battery at baseline, and at their 4-, 8-, and 12-month follow-up visits. Between March 2018 to March 2023, 123 participants were randomized (Positive STEPS = 63; SOC control = 60). Intention-to-treat analyses showed a significant positive main effect for the Positive STEPS arm, which increased the mean log ART adherence by 18.7% relative to the SOC control at the 4-month visit (coefficient=0.187, p=0.021). For the time effect, a significant overall increase in ART adherence across the subsequent follow-up visits was observed, with increased mean log ART adherence by 27.8% (p<0.01) at 8 months and 30.1% at 12 months (p<0.01), relative to the SOC control. With respect to our viral suppression outcome, the analysis revealed a significant negative main effect for the Positive STEPS arm at the 4-month visits (odds ratio [OR]=0.264, p=0.023), indicating that the odds of having an unsuppressed virus were 74% lower in the Positive STEPS arm compared to the SOC control; the interaction term revealed that this effect was maintained through the12-month visit. These findings on the efficacy of Positive STEPS to enhance ART adherence and viral suppression among youth living with HIV represents the first behavioral intervention for youth to show significant and sustained effects on both behavioral (Wisepill and self-report) and biomedical (HIV viral load) outcomes related to ART adherence. The intervention not only demonstrated remarkable efficacy when compared to the SOC control, but also showed maintenance of gains over a 12 month period. Effectiveness and implementation science approaches to testing Positive STEPS in real world settings is recommended.

Specialty Pharmacy Services Compared to Community-Based Pharmacy Services on HIV Viral Load

BackgroundPeople with human immunodeficiency virus (PWH) on antiretroviral therapy (ART) with viral load (VL) suppression eliminate the risk of sexual transmission. Many factors including decreased ART adherence and/or medication access barriers decrease the success of treatment as an HIV prevention strategy. ART access may be enhanced with specialty pharmacy services, but the impact compared to community-based practices is variably reported. ObjectivesCompare the impact of specialty vs community pharmacies on medication adherence via VL assessment. MethodsThis retrospective cohort medical record study investigated whether the use of specialty pharmacies compared to community-based practices significantly improves VL suppression. Patients included were enrolled in the Ryan White HIV/AIDS Program (May 31, 2022-May 30, 2023) at an HIV/Infectious Diseases academic medical center clinic. An undetectable VL was defined as the most recent HIV VL being <50 copies/mL or suppressed as <200 copies/mL. Demographic data collected included age range, race, ethnicity and patient reported gender identity. Pharmacy type was determined via review of prescription refill history linked to the medical record. Results1631 PWH were eligible,179 were excluded and 1452 were included in the analysis. 91.3% were virologically suppressed (N=1326) with an undetectable VL in 83.3% (N=1210). When adjusting for age, self-reported gender identity, race, and ethnicity, PWH using specialty pharmacy services were more likely to have a suppressed (AOR 1.469 95% CI 1.007-2.142) and undetectable VL (AOR 1.396, 95% CI 1.051-1.854), respectively, compared to the use of community-based practices. ConclusionsThe use of specialty compared to community-based pharmacies had a significant, yet modest association with VL suppression in PWH enrolled in Ryan White HIV/AIDS services in this single-academic medical center retrospective analysis. Further studies are needed to determine if mail order services, specifically, without specialty service support, are sufficient for high rates of virologic control.

Examining the Accuracy of Self-Reported Antiretroviral Therapy Adherence Using a Visual Analog Scale Among Opioid-Dependent People Living with HIV.

Evidence indicates that regular assessment of antiretroviral therapy (ART) adherence is necessary to promote adherence and achieve viral suppression. Self-reported adherence using a visual analog scale (VAS) has been used extensively to measure ART adherence. However, less is known about the accuracy of the VAS for measuring ART adherence among opioid-dependent people living with HIV. In this study, we aimed to evaluate the accuracy of the VAS in measuring ART adherence in opioid-dependent people living with HIV who are enrolled in a methadone maintenance program (MMP). This study was conducted within a larger randomized controlled trial among opioid-dependent people living with HIV (N = 109) who were enrolled in an inner-city MMP. Self-reported VAS ART adherence data were compared to pharmacy refill data, which is a more objective measure. Self-reported VAS ratings and pharmacy refill behavior were significantly correlated at the 6-month post-intervention mark (r = 0.349, p = 0.006) but not at any other time point (i.e., pre-intervention, post-intervention, 3-months, and 9-months post-intervention). Based on the pharmacy refill data, participants did not consistently adhere to their ART medication but self-reported high adherence on the VAS. The self-report VAS may not be an accurate measure for assessing ART adherence among opioid-dependent persons living with HIV and enrolled in a MMP. Based on our findings, it may be more accurate to use pharmacy refill information or other objective measures to quantify ART adherence over extended periods for this patient population.

The prevalence of antiretroviral drug interactions with other drugs used in women living with HIV and its association with HIV drug change and patient compliance

BackgroundDrug-drug interactions (DDIs) between antiretroviral therapy (ART) and commonly used co-medications in HIV patients, especially women, impact treatment efficacy and patient safety.ObjectiveThis study aimed to study the prevalence and types of drug-drug interactions (DDIs) between antiretroviral therapy drugs (ARTs) and comedications among a female population with HIV. Additionally, the study investigates the association of these DDIs with ART medication changes and treatment adherence.MethodsThis cross-sectional study included 632 adult women living with HIV (WLHIV). Data was retrospectively extracted from patient files. Drug.com interaction checker website was used to assess DDIs between ART and non-ART medications. Changes to the ART regimen previously attributed to ART side effects or patient non-adherence were considered drug changes.ResultsA total of 429 WLHIV (mean age: 44.05 ± 9.50) were eligible. The prevalence of DDIs between ART and non-ART medications was 21.4%, with 4.7% minor, 18.4% moderate, and 8.9% major interactions. The highest prevalence of DDI was among cardiovascular medication users (71.7%), followed by central nervous system drugs (69.2%). Changing medications resulted in a decrease in DDIs, with significant reductions in total and minor interactions. Participants without DDIs had better adherence to ART. DDI between ART and non-ART medications was significantly associated with ART drug change, even after accounting for side effects attributed to ARTs, indicating an independent twofold association (OR = 1.99, CI 1.04–3.77). Moreover, further adjustments for HIV viral load and CD4 + cell count did not change the significance of the association (OR = 2.01, CI 1.03–3.92).ConclusionDDIs in WLHIV impact adherence to ART. Altering ART may not be directly related to ART side effects, but rather primarily due to interactions with non-ART medications. Modifying non-ART drug regimens can reduce the likelihood of DDIs.

Association of ART regimen and adherence to viral suppression: an observational study of a clinical population of people with HIV

Adherence to antiretroviral therapy (ART) is essential for the effective management of HIV, which includes keeping the HIV viral load undetectable. This study aimed to determine whether certain ART medications are more “forgiving” of poor adherence in achieving viral suppression. We identified subgroups of ART medication usage and determined the extent to which ART adherence is associated with viral suppression across those subgroups. Data came from claims and clinical records (2017–2019) of 3,552 HIV-positive adult members of a Medicaid managed care plan. Pharmacy fill data were examined to characterize ART medications using latent class analysis (LCA), which captures the complexity of real-world ART usage (i.e., multiple medications, ART switching). LCA yielded five ART medication patterns over three years, mostly characterized by recent medications and formulations of ART, though they varied in number of tablets and in medication class. Mixed effects logistic regression models were estimated to determine whether odds of viral suppression differed by ART adherence level. After adjusting for covariates, those with at least 90% adherence (i.e., 90 to < 95%) did not significantly differ from those with 95% adherence or greater in terms of viral suppression, which corroborates existing clinical recommendations. These findings can inform provider-patient communication for people with HIV, especially those who have difficulty maintaining adherence. This includes those experiencing unstable housing, mental health conditions, or substance use.

Level of option B+PMTCT drug adherence with male partner involvement and associated factors among breastfeeding women until 18 months in North Gojjam Zone, Amhara region, Northwest Ethiopia, 2022: a multicentre cross-sectional study

BackgroundAdherence to option B+antiretroviral therapy medication is crucial for the effective implementation of the Prevention of Mother-to-Child Transmission (PMTCT) programme. Ethiopia has adopted the WHO’s target of achieving over 95%...

Highly active antiretroviral therapy adherence among HIV-POSITIVE women in Southern Ethiopia.

Adherence to Highly Active Antiretroviral Therapy (HAART) medication is the major predictor of HIV/AIDS treatment success. Poor adherence to HAART creates the risk of transmitting HIV, deteriorating health conditions, treatment failure, increased occurrences of drug-resistant HIV, morbidity and mortality. The objective of the study was to explore and describe factors influencing HAART adherence among HIV-positive women in Southern Ethiopia. A hospital-based descriptive cross-sectional survey was used among 220 randomly selected respondents. Data was collected with a structured interview guide after each respondent had given consent to take part in the study. The collected data was entered into and analyzed by using the Statistical Package for Social Sciences (SPSS) software program version 27. The level of self-reported adherence (measured by dose) to HAART in the past 30days was found to be 82.7%. In multivariate analysis, the divorced/separated HIV-positive women had poor adherence to their HAART medication as compared to those who were married [AOR: 2.94, 95% CI: (1.02-8.44)]. Respondents who used reminders in their medication were 75% less likely to be poorly adherent to their HAART medication than those who did not use reminders [AOR: 0.25, 95% CI: (0.06-0.97)]. Those who self-reported depression, perceived stigma, and low perceived susceptibility had poor adherence to their HAART than those who did not report depression, perceived stigma, and low perceived susceptibility [AOR:2.34, 95% CI: (1.01-5.42)], [AOR:2.37, 95% CI: (1.06-5.34)], and [AOR: 4.1, 95% CI: (1.53-11.1)] respectively. HIV-positive women who self-reported low perceived severity were poorly adherent to HAART than those who self-reported high perceived severity [AOR: 2.92, 95% CI: (1.14-7.47)]. Factors including being divorced/separated, not using reminders, depression, perceived stigma, perceived susceptibility, and perceived severity negatively impact HIV-positive women's adherence to HAART.

High rate of uncontrolled hypertension among adults receiving integrated HIV and hypertension care with aligned multi-month dispensing in Malawi: results from a cross-sectional survey and retrospective chart review.

People living with HIV have high rates of hypertension. Integrated HIV and hypertension care with aligned multi-month dispensing of medications (MMD) could decrease the burden of care for individuals and health systems. We sought to describe hypertension control and evaluate its association with different durations of MMD among Malawian adults receiving integrated care with aligned dispensing of antiretroviral therapy (ART) and antihypertensive medication. We conducted a cross-sectional survey and retrospective chart review of adults (≥18 years) receiving integrated HIV and hypertension care on medications for both conditions for at least 1 year, with aligned MMD at seven clinics in Malawi. Data were collected from July 2021 to April 2022 and included socio-demographics, clinical characteristics, antihypertensive medications and up to the three most recent blood pressure measurements. Bivariate analyses were used to characterize associations with hypertension control. Uncontrolled hypertension was defined as ≥2 measurements ≥140 and/or ≥90 mmHg. Chart reviews were conducted for a random subset of participants with uncontrolled hypertension to describe antihypertensive medication adjustments in the prior year. We surveyed 459 adults receiving integrated care with aligned dispensing (58% female; median age 54 years). Individuals most commonly received a 3-month aligned dispensing of ART and antihypertensive medications (63%), followed by every 6 months (16%) and every 4 months (15%). Hypertension control was assessed in 359 respondents, of whom only 23% had controlled hypertension; 90% of individuals in this group reported high adherence to blood pressure medications (0-1 missed days/week). Control was more common among those with longer aligned medication dispensing intervals (20% among those with 1- to 3-month dispensing vs. 28% with 4-month dispensing vs. 40% with 6-month dispensing, p = 0.011). Chart reviews were conducted for 147 individuals with uncontrolled hypertension. Most had high self-reported adherence to blood pressure medications (89% missing 0-1 days/week); however, only 10% had their antihypertensive medication regimen changed in the prior year. Uncontrolled hypertension was common among Malawian adults receiving integrated care with aligned MMD and was associated with shorter refill intervals and few antihypertensive medication escalations. Integrated care with aligned MMD is promising, but further work is needed to understand how to optimize hypertension outcomes.

Antiretroviral Therapy and Cardiovascular Risk in People With HIV in the United States-An Updated Analysis.

Several antiretroviral therapy (ART) medications have been associated with increased cardiovascular risk, but less is known about the safety of modern ART. We sought to compare the risk of major adverse cardiac events (MACEs) among different ART regimens. Using insurance claims databases from 2008 to 2020, we identified adults aged <65 years who newly initiated ART. We compared non-nucleoside reverse transcriptase inhibitor (NNRTI)-based regimens to protease inhibitors (PI)- and integrase inhibitors (INSTI)-based regimens. We used propensity score-weighted Kaplan-Meier functions to estimate the 6, 12, 18, 24, 36, and 48 months' risk and risk differences (RD) of MACE. Among 37 935 ART initiators (median age, 40 years; 23% female; 26% Medicaid-insured), 45% started INSTI-, 16% PI-, and 39% NNRTI-based regimens. MACE occurred in 418 individuals (1.1%) within 48 months after ART initiation. Compared to NNRTI initiators, the risk of MACE was higher at 12 months (RD, 0.50; 95% CI, 0.14-0.99), 18 months (RD, 0.53; 95% CI, 0.11-1.06), and 24 months (RD, 0.62; 95% CI, 0.04-1.29) for PI initiators, and at 12 (RD, 0.20; 95% CI, 0.03-0.37) and 18 months (RD, 0.31; 95% CI, 0.06-0.54) for INSTI initiators; the precision of estimates was limited for longer duration of follow-up. Among ART initiators, PI-based and INSTI-based regimens were associated with higher short-term risk of MACE compared to NNRTI-based regimens. The pattern of association between INSTIs and PIs with excess risk of MACE was similar.

Predictors of Poor Adherence to Antiretroviral Treatment among HIV Positive Patients at Tamale West Hospital, Ghana

Background: Adherence to Antiretroviral therapy is necessary to reduce the viral load of people diagnosed with HIV and help boost the persons’ immunity against opportunistic infections due to the virus. Therefore, this study aimed to assess the level of adherence to ART and its associated factors among HIV clients at the Tamale west hospital. Methods: The current study employed a descriptive study design, and sampled a total of 104 clients receiving ART in the Tamale West Hospital in the Northern Region of Ghana. Results: The results showed that weekly adherence was 94.2%, monthly adherence (76%), quarterly adherence (71%), half yearly adherence (51.9%) and only 33.7% have religiously adhered to ART medication from the initiation of their treatment. The treatment profile of the clients revealed that the majority of them (44.7%) had been receiving antiretroviral therapy (ART) for a duration of 5 years. Additionally, 25.2% had been on ART for 1 year, while 22.3% had been on the treatment for a period ranging from 6 to 10 years. Educational level [(CI: -0.101, 0.001), p&lt;0.052], forgetfulness [(CI: 0.186, 0.581), p&lt;0.001], side effects [(CI: 0.072, 0.400), p&lt;0.005], education on medication [(CI: 0.015, 0.540), p&lt;0.038], confidentiality of services [(CI: 0.012, 0.543), p&lt;0.041], and cost of transportation to treatment centre [(CI: 0.006, 0.167), p&lt;0.035] were significantly associated with treatment adherence to ART among the clients. Conclusions: The adherence rate as determined in the current study did not meet the expected target set by the Ghana National AIDS control programme. A continuous friendly ART services and an intervention to cater for the transport cost of clients would have helped improve adherence among the study clients.

Factors influencing adherence to antiretroviral therapy among young adults in Limpopo province.

South Africa is among the countries with the greatest burden of human immunodeficiency virus (HIV) in the world. The introduction of antiretroviral therapy (ART) has made HIV a manageable chronic health condition with a return to normal life expectancy. Adherence to ART is a prerequisite to realising these benefits. A qualitative study was conducted using individual semi-structured interviews to understand factors influencing adherence to ART among young adults. The study was conducted at three busy primary care clinics around Mankweng Hospital. Participants aged 18-35 years who had been on ART for more than a year were purposefully selected. Open-ended questions were used to explore factors that influence ART. Recorded interviews were transcribed verbatim and translated. The coded transcripts were thematically analysed. Eight major themes were identified to influence ART adherence among young adults: medication-related factors, healthcare system factors, attitudes of healthcare workers, economic factors, disclosure, acceptance, mobile phone reminders and family support. Adherence to ART is a major problem in our communities, and people living with HIV are still finding it challenging to optimally adhere to their ART medication because of the identified factors that influence ART adherence. Family support is a significant factor that was identified to positively influence ART as it leads to disclosure and acceptance of HIV-positive status, better emotional well-being and subsequently improved ART adherence.Contribution:This study underscores the importance of a family-oriented, patient-centred care approach in managing HIV and ART adherence.

Long-acting injectable ART to advance health equity: a descriptive analysis of US clinic perspectives on barriers, needed support and programme goals for implementation from applications to the ALAI UP Project.

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. 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. 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). 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.

The effect of late presentation on HIV related mortality among adolescents in public hospitals of north showa zone Oromiya, Ethiopia; 2022: a retrospective cohort study

BackgroundLate human immunodeficiency virus (HIV) diagnosis is the most prominent cause of HIV/AIDS-related mortality and also increases the risk of transmission and spread of the disease in society. Adolescents are the most vulnerable population’s age group for HIV infection in several settings, but expanding access to early HIV testing remains a challenge. Consequently, a significant proportion of adolescents are still dying of HIV-related causes, and the current study aimed at assessing the effect of late presentation on HIV-related mortality among adolescents living with HIV.MethodsAn institutional-based retrospective cohort study was conducted from August 21–November 21, 2022, at selected public hospitals in the North Showa Zone of Oromiya, Ethiopia. All adolescents living with HIV who had received no ART and presented for ART follow-up at public hospitals from September 1, 2012, to August 31, 2021, were included in the study. Data entry was done by Epi-data version 3.1.1 software and exported to Stata version 16 for further analysis. Both bi-variable and multivariable analyses were performed using the Cox proportional hazard model to compare the HIV-related mortality of early and late-presented adolescents using an adjusted hazard ratio at a 95% confidence interval (CI).ResultsA total of 341 medical records of adolescents were included in the study, contributing an overall incidence rate of 3.15 (95% CI: 2.21–4.26) deaths per 100 person-years of observation throughout the total follow-up period of 1173.98 person-years. Adolescents with late presentation for HIV care had three times the higher hazard of mortality (adjusted hazard ratio (aHR) = 3.00; 95% CI: 1.22–7.37) as compared to those with early presentation for HIV/AIDS care. Adolescents within the age range of 15–19 years old (aHR = 3.56; 95% CI: 1.44–8.77), rural residence (aHR = 2.81; 95% CI: 1.39–5.68), poor adherence to ART (aHR = 3.17; 95% CI: 1.49–6.76), and being anemic (aHR = 3.09; 95% CI: 1.52–6.29) were other independent predictors of HIV-related mortality.ConclusionThe study found a substantial link between HIV late presentation to care and mortality among adolescents. Residence, age, antiretroviral therapy (ART) medication adherence, and anemia status were also found to be other independent predictors of HIV-related mortality. To achieve the ultimate aim of lowering mortality among adolescents living with HIV, rigorous emphasis must be placed on early presentation for HIV/AIDS care. In addition, counseling on adherence and prompt diagnosis and treatment of anemia are highly recommended to reduce mortality.

Study on HIV Status Disclosure and Treatment Adherence Amongst Support Group Members in Mushin Local Government Area (LGA), Lagos State

Human Immunodeficiency Virus (HIV) remains a significant global health concern, particularly in sub-Saharan Africa, where the burden of the epidemic is highest. Lagos State, in Southwest Nigeria, faces a significant challenge with HIV prevalence, particularly in the Mushin Local Government Area (LGA). This study investigates the relationship between HIV status disclosure and adherence to Antiretroviral Therapy (ART) medication among members of the God is Good Support Group in Mushin LGA, Lagos State, Nigeria. The study used a qualitative framework design and conducted semi-structured interviews with twenty members of the support group who were purposely selected due to the specific nature of the target population. Collected data was manually transcribed, while thematic analysis was used to analyze the interview data. The results showed that the majority of participants in the support group had disclosed their HIV status to their partners, and those who hadn&amp;apos;t disclosed often confided in children or close relatives. Participants reported receiving strong support from their confidantes after disclosure. Participants believed that effective treatment adherence is crucial for achieving viral suppression, and a significant majority believed that disclosing their HIV status helped them achieve viral suppression. Most participants had positive experiences disclosing their status to partners, with nearly all reporting supportive partners. Only a small minority reported negative impacts on their sexual life, suggesting that disclosure may not necessarily harm relationships. Based on these findings, the study concludes that there is a high level of disclosure among support group members, and participants with good adherence were more likely to have disclosed their status. Disclosure was associated with achieving viral suppression, potentially due to the support received. The study suggests that strengthening support groups through funding from local, state, and international organizations could be beneficial in encouraging disclosure and improving health outcomes for individuals living with HIV.

Renal safety of tenofovir alafenamide-based antiretroviral therapy in people with HIV: A mini-review

Antiretroviral therapy (ART) has significantly enhanced the outlook for people with HIV(PWH), yet certain ART medications can adversely affect the renal function of these patients. Of particular concern is the nephrotoxicity associated with tenofovir disoproxil fumarate (TDF). Compared to TDF, tenofovir alafenamide (TAF), another prodrug of tenofovir (TFV), results in lower TFV plasma levels, thereby alleviating the TFV-associated mitochondrial toxicity on proximal renal tubular cells. Currently, numerous clinical trials and real-world studies have demonstrated the favorable renal safety profile of ART regimens incorporating TAF for PWH. This paper seeks to consolidate the available evidence regarding the renal safety of TAF-based regimens in PWH, encompassing both the general PWH and those with renal impairment or predisposing factors, in order to offer recommendations and insights for TAF clinical application.

An exploratory study of community violence and HIV care engagement among Black gay and bisexual men

ABSTRACT This study examined the relationship between exposure to community violence and HIV care engagement among 107 Black gay or bisexual men living with HIV in Chicago. Measures assessed the importance of demographic covariates (age, annual income, health insurance status, and years living with HIV), community violence exposures, mental health, social support, in explaining variations in missed doses of antiretroviral therapy (ART) medication and missed HIV care appointments. Results showed that participants who reported higher rates of exposure to community violence were two times more likely to have missed ART doses and HIV care appointments. Participants who reported depression scores were two times more likely to have greater non-ART adherence. Finally, older participants were more likely to report fewer missed ART doses. More research is needed to clarify the mechanisms between age or depression and ART adherence given community violence exposure. Health care providers should screen for depression when attempting to promote better ART adherence and keeping HIV care appointments for Black gay and bisexual men living with HIV. Younger Black gay and bisexual men living with HIV may be more vulnerable than older men for missed ART doses and may require additional screening and follow-up.

AGING WITH HIV: ASSOCIATION OF ART REGIMEN AND ADHERENCE TO VIRAL SUPPRESSION

Abstract Adherence to antiretroviral therapy (ART) is essential to effective management of HIV among an increasing population of older adults. Newer ART regimens are more “forgiving” of poor adherence allowing for viral suppression at lower adherence levels (i.e., &amp;lt; 90%). This is especially promising for some older adults who may struggle with adherence due to high rates of multimorbidity and polypharmacy. We aimed to determine how ART forgiveness varies depending on ART type and adherence. Data came from 2017-2019 claims and clinical records of 1,044 HIV-positive members of a Medicaid managed care plan who were 50 to 65 years of age. Pharmacy fill data were examined on a quarterly basis to characterize ART medications using latent class analysis (LCA), which captures the complexity of real-world ART usage (i.e., multiple medications, ART switching). LCA yielded five distinct ART utilization patterns over three years, mostly characterized by recent medications and formulations of ART, though they varied in number of tablets and in medication class (e.g., boosted protease inhibitors). Logistic regression models adjusting for demographics and health-related covariates revealed that ART medication patterns did not consistently differ in odds of maintaining viral suppression across adherence levels (&amp;lt; 50%, 50% to &amp;lt; 80%, 80% to &amp;lt; 85%, 85% to &amp;lt; 90%, and &amp;gt;=90%). In contrast, other factors, including nadir CD4 count and behavioral health conditions, were related to viral suppression across models. This highlights the importance of life-course illness trajectories when considering disease management and treatment strategies for older adults living with HIV, especially those with difficulty maintaining near-perfect adherence.

Feasibility of Lantern Using WhatsApp to Improve Antiretroviral Therapy Adherence.

This pilot study tested the feasibility of Lantern program, an adherence program to HIV medications using WhatsApp, a secure social media messaging application from Meta, for a smartphone-based platform to enhance medication-taking adherence of antiretroviral therapy among people living with HIV in Indonesia. Thirty participants were recruited for this 8-week study. We recruited persons if they had taken antiretroviral therapy for at least 3 months prior to the study, had a smartphone, Internet access, and could use Lantern with WhatsApp. Here, we report the results from the focus group discussions, with the participants evaluating the qualitative aspects of the experiences. The WhatsApp platform was found to be safe, practical, and relatively inexpensive and provided confidentiality for the participants. Three themes emerged from the focus groups: the study motivated participants to take their antiretroviral therapy medications on time, they still set medication reminder alarms, and being in the study made them feel supported. The Lantern program indicated good feasibility and acceptability for adherence to antiretroviral therapies among people living with HIV. Future research should examine on how community organizations and healthcare providers can take advantage of the WhatsApp program to improve adherence to antiretroviral therapies.

Antiretroviral Therapy Concealment Behaviors and their Association with Antiretroviral Therapy Adherence among People with HIV: Findings from the Florida Cohort Study.

Little is known about HIV medication concealment behaviors and the effect of medication concealment on antiretroviral therapy (ART) adherence among people with HIV (PWH). This study aims to (1) to describe medication concealment behaviors and factors associated with these behaviors, and (2) assess the association between medication concealment and suboptimal ART adherence. The Florida Cohort Study enrolled adult PWH from community-based clinics around the state from October 2020 to September 2022 (n = 416, 62% aged 50+, 56% male, 44% non-Hispanic Black, 18% Hispanic). Participants responded to questions about sociodemographics, stigma, ART adherence (≥ 85%), symptoms of depression, social networks and disclosure to their networks, and actions to conceal ART to avoid inadvertent disclosure of their HIV status. Analyses were conducted using multivariable logistic regressions models. The most common concealment behavior was hiding ART while having guests over (32%), followed by removing ART labels (26%), and putting ART into a different bottle (16%). Overall, 43% reported ≥ 1 behavior. In multivariable models, depressive symptoms, incomplete disclosure of HIV to close social networks, and not having a close social network were associated with ART concealment. After adjusting for risk factors for suboptimal ART adherence, endorsing hiding medication while having guests was associated with suboptimal ART adherence (aOR 2.87, 95% CI 1.15-7.55). Taking any action and other individual behaviors were not associated. ART concealment behaviors were common but did not consistently negatively influence adherence when accounting for other factors. PWH may want to receive ART medications in ways that ensure privacy and reduce the risk of inadvertent disclosure.

Medication Adherence, Barriers to Adherence and Treatment Satisfaction with Antiretroviral Therapy Among Adolescents Living with HIV in Lagos, Nigeria

Background: The advent of antiretroviral therapy (ART) in controlling Human Immunodeficiency Virus (HIV) disease has been quite effective in ensuring that infected people can enjoy healthy, long, and productive lives. Medication adherence is an essential part of patient care, especially among patients with HIV, as it greatly determines the effectiveness of treatment. Few studies have explored factors influencing medication adherence and treatment satisfaction among adults, with little focus on adolescents. Objectives: To assess medication adherence, treatment satisfaction and factors influencing adherence to ART medication among adolescents living with HIV in Lagos, Nigeria. Methods: This descriptive, cross-sectional study was conducted among diagnosed and registered adolescents aged 10-19 years living with HIV and receiving treatment at eight selected antiretroviral centres in Lagos state, Nigeria. A total of 203 adolescents were recruited in stages, and data were collected using an interviewer-administered semi-structured questionnaire. Results: There was a low level of adherence as only 59/203 (29.1%) of the respondents adhered to ART. Depression, perceived stigma, being away from home, side effects of drugs, pill burden, and forgetfulness were some factors identified as barriers to adherence. The respondents were most satisfied with the effectiveness of the medication and least satisfied with the side effects. Conclusions: Medication adherence among adolescents was relatively low; the level of satisfaction with ART medication is an entity that significantly impacts adherence.
