Visual analogue scale (VAS) measurement of antiretroviral adherence in people living with HIV (PLWH): a meta-analysis

Tailoring a Skills-Based Serostatus Disclosure Intervention for Transgender Women in South Africa: Protocol for a Usability and Feasibility Study

BACKGROUND

Transgender women have few interventions to support their HIV prevention and treatment outcomes in South Africa. Further, increased focus should be on intervention development that will reduce HIV transmission within HIV-discordant partnerships, especially for transgender women who navigate gender, sexuality, and relationship stigma. The Speaking Out and Allying Relationships (SOAR) intervention has been developed for sexual minority men to address these outcomes in South Africa. It is a behavioral intervention that is delivered in groups via videoconference to develop coping skills to manage HIV-related stress, assist with disclosure to partners, and establish and maintain safer sex practices with partners. Tailoring SOAR may be feasible for transgender women to support their HIV care while reducing transmission within their relationships.

OBJECTIVE

This study aims to (1) adapt SOAR for transgender women and test its usability, then (2) assess its feasibility.

METHODS

To achieve aim 1, we will use a human-centered design approach to tailor the existing SOAR intervention for transgender women. Interviews and a survey will be administered to transgender women (N=15) to assess intervention preferences. Findings will be used to tailor content like roleplays, scenarios, and media to align with transgender women's lived experiences navigating HIV and relationships. Afterward, we will conduct a usability test with 7 (47%) of the 15 participants to determine intervention understanding and satisfaction. Participants will be transgender women living with HIV and in a relationship with a man who has unknown HIV status or is HIV-negative. All participants will be recruited using community-based approaches. In aim 2, we will examine SOAR feasibility using a 1-arm pilot study. Transgender women (N=20) will be recruited using aim 1 methods and eligibility criteria, with participants completing feasibility surveys and interviews, as well as behavioral and biomedical assessments.

RESULTS

Intervention adaptation began in May 2023 with interviews. Feasibility pilot testing was conducted with 14 transgender women, with study completion in January 2025.

CONCLUSIONS

Transgender women need more intervention options that engage their relationships since these can present barriers to HIV treatment outcomes like hindering viral suppression in South Africa. Delivering an existing yet tailored intervention via videoconference expands its reach to transgender women and allows them to engage with others and learn new skills in a secure setting like their homes. SOAR has the potential to improve relationship dynamics and reduce violence, which will in turn enhance HIV treatment and prevention engagement.

Multilevel Intervention to Support Tailored and Responsive HIV Pre-Exposure Prophylaxis Care in Rural North Carolina: Protocol for a Randomized Controlled Trial

BACKGROUND

While access to pre-exposure prophylaxis (PrEP) is an important tool for reducing HIV incidence in the United States, disparities in uptake by race, sex, socioeconomic status, and geography persist. In 2018, the US South accounted for more than half of all new HIV diagnoses but only one-third of PrEP users. PrEP use in North Carolina (NC) similarly lags, with uptake being the lowest among young, sexual and gender minority populations, who account for nearly two-thirds of the state's incident infections. The PrEP-to-need ratio, a metric of PrEP equity that measures PrEP uptake relative to new HIV diagnoses, highlights disparities in PrEP uptake among specific demographic groups such as women and Black, Hispanic, and Southern people, indicating that these groups are underserved relative to their epidemic need. Despite behavioral risk overlap of incident sexually transmitted infections (STIs) and HIV, in NC, PrEP is only offered at a few primarily urban health department-affiliated STI clinics. The lack of robust health care infrastructure in these areas presents challenges for HIV prevention services.

OBJECTIVE

This protocol describes a randomized controlled trial of a multilevel PrEP intervention recruiting from rural and periurban STI clinics.

METHODS

This trial aims to enroll up to 336 participants and randomly assign them 1:1 to either the intervention or control group. The intervention consists of access to a digital health app, linkage to a remote PrEP navigator, and the option of referral to telehealth-based PrEP services. Persons randomly assigned to the control condition will receive an enhanced standard of care, including access to a limited version of the digital health app. All participants will be followed up on quarterly for at least 3 months. The primary outcome is the initiation of PrEP within 3 months of an index STI clinic visit; secondary outcomes evaluate PrEP care engagement and adherence, incident HIV and bacterial STI infections, PrEP stigma, and cost-effectiveness. Binary outcome analyses will estimate the proportion of participants achieving an event (eg, PrEP uptake) in each arm and a probability difference and the corresponding 95% CI to compare the intervention versus control arm at each time point. Continuous end points will use nonparametric Wilcoxon rank sum tests comparing the intervention and control groups.

RESULTS

Enrollment opened on August 31, 2023, at 15 health departments in NC and subsequently expanded to 21 facilities in 20 counties by July 2024. Completion of the enrollment and data collection phases is expected by May 2025. Results will be published thereafter.

CONCLUSIONS

This study directly addresses multiple barriers to PrEP use in rural and periurban areas of the Southeastern United States and can inform policy and programming that seek to expand PrEP access and promote use in underserved communities.

Developing and Implementing Provider-Training and Evidence-Based Tools to Support Pre-exposure Prophylaxis (PrEP) Decision-Making and Increase PrEP Adherence Among Young Men Who Have Sex With Men: Protocol for the PrEP Choice Longitudinal Cohort Study

BACKGROUND

Despite the availability of highly effective HIV pre-exposure prophylaxis (PrEP), uptake and adherence to PrEP among young men who have sex with men (YMSM) remains low, limiting its impact on the prevention of HIV infection. Strategies that incorporate an array of prevention options and provide YMSM and their providers with tailored education and support tools, including tools to support shared decision-making, are needed.

OBJECTIVE

The goals of the Centers for Disease Control and Prevention (CDC)-funded PrEP Choice study include the development and deployment of CDC guideline-consistent PrEP provider training and the implementation of evidence-based provider- and client-facing PrEP education and support tools. Under this initiative, the CDC funded 2 research projects, Florida State University (the Expanding PrEP in Communities of Color [EPICC] project), and Columbia University (the mChoice project).

METHODS

Providers from both projects will complete the PrEP Choice online training, which was developed to educate providers on PrEP options and how to engage clients in open discussions around sexual health and PrEP options. EPICC project providers will also attend online tailored motivational interviewing (TMI) training sessions, and mChoice project providers will view a training video on cultural competency and humility in PrEP care. Following training, each project will enroll a cohort of 400 participants receiving care from study providers and follow them for 12-18 months. Participants will complete online surveys every 3 months and provide biomarkers to assess PrEP adherence. Electronic health record (EHR) data will be collected every 6 months to provide additional information on clinic attendance, PrEP prescriptions, and HIV/sexually transmitted infection (STI) testing. Each project will provide cohort participants with a unique digital health tool to support the PrEP choice and ongoing adherence. The study will assess the effectiveness of training and educational and support tools in practice and the critical factors associated with the successful uptake of and adherence to PrEP by participants. The study will also monitor patterns of PrEP use among YMSM, including types of PrEP and switching between types.

RESULTS

Formative work to develop and prepare the tools for implementation was completed in 2023. The EPICC project began provider training in early 2024, and the mChoice project began in spring 2024. Cohort enrollment for both projects began after provider training began.

CONCLUSIONS

Given the changing PrEP landscape, implementation of provider education and tools to maximize uptake and adherence is needed. By delivering culturally competent and interactive provider training on PrEP options, the study will help providers counsel and guide participants on the effective and safe use of PrEP. The digital health tools created will support participant adherence to help them optimize PrEP benefits. Through the cohort design, the PrEP Choice study will provide real-world data about PrEP use that will be critical for informing future guidelines and tools.

Evaluation of a Cohort-Based Healthy Aging With HIV Wellness Pilot Intervention: "People Aging and Thriving With HIV" in Colorado

ABSTRACT

The aging population of people living with HIV (PLWH) face unique health and social challenges. We piloted a community-based wellness program, People Aging and Thriving with HIV (PATH2Wellness), aiming to improve health outcomes through physical activity, nutritional counseling, and social support within Colorado Health Network, a statewide AIDS service organization. Participants ages 50+ were recruited into three cohorts between September 2020 and December 2021. Weekly step counts and psychosocial measures were collected. Overall, while there were no statistically significant improvements in step count or secondary outcomes (including depression, social connectedness, self-reported physical function, and quality of life [all p ≥ .55]), participants noted a high level of satisfaction. Ongoing feedback led to modifications for program improvement; as such, PATH2Wellness shows promise in improving mental health and social connectedness, and findings underscore the importance of tailored programs for older PLWH, suggesting avenues for research and program development.

A Stepped-Wedge, Cluster-Randomized, Multisite Study of Text Messaging Plus Peer Navigation to Improve Adherence and Viral Suppression Among Youth on Antiretroviral Therapy

BACKGROUND

To address the need for improved virologic suppression among youth living with HIV (YLH) on antiretroviral treatment (ART), we evaluated peer navigation plus TXTXT daily text message ART reminders.

SETTING

YLH aged 15-24 years on ART for at least 3 months at 6 research sites in 4 Nigerian cities.

METHODS

Using a stepped-wedge design, cluster 1 was nonrandomized, whereas clusters 2 and 3 were randomized to sequences of routine care (control period) and 48 weeks of the combination intervention (intervention period). The primary end point was viral suppression (HIV-1 RNA <200 copies/mL) at week 48 of the intervention. Secondary end points included adherence measured by self-report ( 90% considered adherent). Post hoc analysis assessed virologic control at <50 copies per milliliter and <1000 copies per milliliter. Generalized estimating equations determined the difference between intervention and control periods in the intention-to-treat population.

RESULTS

We enrolled 558 YLH and followed 541 over time, mean age 18 years, 53.8% female, 71.7% perinatally infected, and 38.6% virologically nonsuppressed at enrollment. For the primary end point, the intervention periods displayed a small, nonsignificant increase in viral suppression < 200 copies per milliliter [odds ratio (OR) = 1.16 (0.88-1.54), P = 0.297]. There was a significant effect of the combination intervention on virologic control <1000 copies per milliliter (OR = 1.42 [1.03-1.94], P = 0.030). Self-reported adherence also improved (OR = 2.07 [1.46-2.95], P < 0.001).

CONCLUSIONS

Peer navigation plus daily text message ART reminders demonstrated limited benefit among ART-experienced, predominantly perinatally infected YLH, with no significant effect on viral suppression below 200 copies per milliliter despite improvement in self-reported adherence.

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.

Influence of Stigma on Engagement in HIV Care and Adherence to Antiretroviral Therapy in Specialized HIV Clinics Targeting Men Who Have Sex with Men and Transgender Women in Lima, Peru

HIV stigma is a social determinant of health that can influence multiple health outcomes, including adherence to antiretroviral therapy (ART), engagement in HIV care, and viral suppression levels in people with HIV (PWH). In Peru, where the HIV epidemic is concentrated in men who have sex with men (MSM) and transgender women (TGW), stigma may play an important role in healthcare engagement. To understand the relationship between stigma and two outcome variables, ART adherence and engagement in HIV care in 400 MSM and TGW, we assessed factors from the Behavioral Model for Vulnerable Populations at two HIV clinics that tailor services for sexual and gender minorities. While some predisposing, need, and enabling resource factors were associated with optimal (≥ 90%) ART adherence or engagement in HIV care, none of the stigma subscales were correlated, suggesting that when LGBTQ-affirming care is provided to MSM/TGW, stigma may not influence HIV-related outcomes.

Perceived sensitivity to medicines and medication concerns beliefs predict intentional nonadherence to antiretroviral therapy among young people living with HIV

Objective: Among the sources of antiretroviral therapy (ART) nonadherence are patient decisions to skip or stop taking their medications, often stemming from medication beliefs and concerns about side- effects. While individuals who perceive greater sensitivity to medicines may be prone to medication concerns, understanding how these factors contribute to HIV treatment adherence requires further research. The current study tested the direct and indirect effects of perceived sensitivity to medicines on intentional nonadherence to ART, and whether medication concerns mediate this association.

Methods: A sample of 418 younger (< 36 years of age) people living with HIV was recruited through community outreach to complete assessments of perceived sensitivity to medicines, medication concerns beliefs, adherence assessed by unannounced phone- based pill counts and HIV viral load, as well as monthly follow- up assessments of intentional nonadherence over a 15- month period.

Results: Analyses at baseline and prospective Poisson regression models conducted over 15- months converged to show that perceived sensitivity to medicines significantly predicted intentional nonadherence to ART through medication concerns.

Conclusions: These findings suggest that people who perceive greater sensitivity to medicines are prone to greater medication concerns that are related to intentional nonadherence. Cognitive behavioral interventions are needed to resolve medication concerns and reduce intentional nonadherence among people receiving ART.

Main Partner Relationships and the HIV Care Cascade: Examining the Predictive Utility of Sexual Agreements, Partner Concordance, and Drug Use Among Sexual Minority Men Living With HIV in the USA

BACKGROUND

The past 15 years have seen increasing attention to relationship factors among sexual minority male (SMM) couples at high risk for HIV infection. Research has largely focused on HIV prevention outcomes. Outcomes relevant to SMM living with HIV have received relatively less attention.

PURPOSE

This study evaluated associations between relational covariates (relationship status, sexual agreements, and seroconcordance) and HIV care cascade outcomes (having a current antiretroviral therapy [ART] prescription, ART adherence, viral load (VL) testing, and VL detectability) above and beyond cannabis and stimulant drug use.

METHODS

Adult SMM (n = 36,874) living with HIV in the USA were recruited between November 1, 2017 and March 15, 2020 through social networking applications. They completed a cross-sectional survey online.

RESULTS

Nonmonogamous SMM with serodiscordant partners were most likely to have an ART prescription. Those with seroconcordant partners (regardless of sexual agreements) were least likely to be adherent. While relational covariates were not associated with VL testing, SMM in nonmonogamous relationships with serodiscordant partners were significantly more likely to have an undetectable VL. Those in monogamous relationships with seroconcordant partners were significantly less likely to have an undetectable VL.

CONCLUSIONS

SMM with seroconcordant partners and monogamous sexual agreements may experience diminished interpersonal motivation for HIV care engagement. HIV care cascade retention messages that emphasize the prevention of onward transmission may have limited relevance for these SMM. Novel intervention strategies are needed to enhance HIV care outcomes in this population, ideally ones that incorporate attention to drug use.

Changes in Adherence and Viral Load Suppression Among People with HIV in Manila: Outcomes of the Philippines Connect for Life Study

The Philippines HIV epidemic is among the fastest growing globally. Infections among men who have sex with men are rising at an alarming rate, necessitating targeted evidence-based interventions to retain people living with HIV in care, support adherence, and reach viral suppression. We conducted a 48-week prospective cohort study of 462 participants in which we provided a mobile health (mHealth) adherence support intervention using the Connect for Life platform. We observed an improvement in adherence, with the proportion of participants taking more than 95% of their antiretroviral therapy (ART) doses increasing from 78.6% at baseline to 90.3% at 48 weeks. Among treatment experienced participants, adherence improved significantly (McNemar's test = 21.88, P < 0.001). Viral load suppression did not change, with 92.6% suppression at baseline and 92.0% at 48 weeks. Illicit drug use was associated with reduced adherence (aOR = 0.56, 95%CI 0.31-1.00, P = 0.05) and being on second-line therapy was associated with poor viral load suppression (aOR = 0.33, 95%CI 0.14-0.78, P = 0.01). Quality of life improved following ART initiation, from a mean of 84.6 points (of a possible 120) at baseline to 91.01 at 48 weeks. Due to technical issues, fidelity to the intended intervention was low, with 22.1% (102/462) of participants receiving any voice calls and most others receiving a scaled-back SMS intervention. The mHealth intervention did not have any observed effect on adherence or on viral load suppression. While evidence of effectiveness of mHealth adherence interventions is mixed, these platforms should continue to be explored as part of differentiated treatment support services.

The three-item patient-reported instrument for retrospective adherence in resource constrained settings: reliability, validity and potential utility

INTRODUCTION

Patient-report instruments remain the most feasible and sustainable approaches for monitoring medication adherence in clinical settings. However, questions of their reliability and validity persist. Studies suggest that the 3-item instrument for retrospective adherence (IRA) developed by Wilson et al. offers a viable option for clinically monitoring medication adherence. Here we report the reliability and validity of the IRA among patients recruited from community-based HIV clinics and antiretroviral therapy (ART) dispensaries in a resource constrained township in Cape Town, South Africa.

METHODS

Women (n = 794) and men (n = 228) receiving ART completed the IRA at three time points: (a) in a face-to-face administration at enrollment (b) in1-week phone interview and (c) 1-month phone interview. Participants also provided contemporaneous blood samples for HIV viral load testing as a clinical outcome and unannounced phone-based pill counts as an objective assessment of ART adherence.

RESULTS

The IRA was internally consistent and showed evidence of time stability. The IRA also demonstrated validity with respect to pill count adherence, correlates of adherence, and HIV viral load. Response operating curve analysis yielded an area under the curve of 0.646, using 75% adherence as the cut-off, with 0.637 sensitivity and 0.567 specificity.

CONCLUSIONS

The IRA demonstrated reliability, construct validity and criterion validity in a resource constrained setting, supporting use of the IRA in research and clinical care.

Effects of Telephone-Based Brief Motivational Interviewing on Self-Management, Medication Adherence, and Glycemic Control in Patients with Uncontrolled Type 2 Diabetes Mellitus in a Rural Community in Thailand

Introduction

Owing to the increased prevalence of type 2 diabetes mellitus (T2DM) and the high proportion of patients with uncontrolled T2DM, effective interventions for disease management are needed.

Objective

The study aim was to test the effects of brief motivational interviewing (MI) on patients' self-management, medication adherence, and glycemic control.

Methods

A single-group repeated measures trial was used to examine the effects of usual care only and usual care plus telephone-based brief MI. Participants were 29 patients with uncontrolled T2DM recruited from a rural primary care setting in Nakhon Sawan, Thailand. Participants received usual care during the first 4 weeks, followed by usual care plus brief MI during weeks 4-8. Outcomes of self-management, medication adherence, fasting blood sugar (FBS) levels, and hemoglobin A1c (HbA1c) levels were assessed at baseline, 4 weeks, and 8 weeks. Data were analyzed using descriptive statistics, one-way repeated measures analysis of variance, and Friedman test.

Results

Significant changes in self-management (p < 0.001), medication adherence (p < 0.001), and FBS (p < 0.05) were observed over the 8-week study. In multiple comparisons, self-management was the only parameter significantly different across baseline, 4, and 8 weeks (p <0.05, <0.001, and <0.001, respectively); medication adherence was significantly different between 4 and 8 weeks (p < 0.05), and between baseline and 8 weeks (p < 0.001); and FBS was significantly different between 4 and 8 weeks (p < 0.05). HbA1c declined over the 8-week study, but not significantly.

Conclusion

An intervention combining telephone-based brief MI with usual care significantly increased self-management, medication adherence, and glycemic control (ie, FBS) after 4 weeks, whereas usual care only significantly increased self-management. Phone-based brief MI may be an effective way for healthcare providers to remotely enhance patients' self-management and glycemic control, thus reducing barriers related to time and geographic location.

Socio-ecological Barriers to Viral Suppression Among Transgender Women Living with HIV in San Francisco and Los Angeles, California

Troubling disparities in viral suppression persist among transgender (trans) women living with HIV in the US. We utilized baseline data from a randomized controlled trial of a behavioral intervention among trans women living with HIV in San Francisco and Los Angeles, to identify the socio-ecological correlates of biologically confirmed viral suppression (< 200 HIV-1 RNA copies/mL). Among 253 participants, the mean age was 43 (SD = 11), 46% identified as Black or African American and 35% were virally non-suppressed. In adjusted Poisson regression models, the following barriers to viral suppression were identified: injection drug use [adjusted risk ratio (aRR) 0.78, 95% CI 0.65-0.93, Z = - 2.64, p = 0.008], methamphetamine use (aRR 0.65, 95% CI 0.51-0.83, Z = - 3.45, p = 0.001), amphetamine use (aRR 0.62, 95% CI 0.44-0.87, Z = - 2.75, p = 0.006), homelessness (aRR 0.79, 95% CI 0.63-0.98, Z = - 2.06, p = 0.039), and sex work (aRR 0.60, 95% CI 0.41-0.86, Z = - 2.77, p = 0.009). These findings underscore the importance of interventions that address the socio-ecological barriers to viral suppression among trans women in urban settings.

Antiretroviral therapy non-adherence and its relationship with cognitive impairment, alcohol use disorder, and depression in adolescents living with HIV

OBJECTIVE

We aimed to compare antiretroviral non-adherence in the behaviourally infected (BIAs) and congenitally infected adolescents (CIAs) and explore its associations with depression, cognitive impairment, and alcohol use disorder (AUD) in adolescents living with HIV(ALWHIV) in Botswana.

METHODS

This study was a cross-sectional, comparative, multi-center research that involved collecting samples from different HIV clinics in Botswana. Of the 622 ALWHIV, 223 were identified as BIAs and 399 as CIAs. They were evaluated using various tools such as MINI-KID for psychiatric disorders, DSM-5 for AUD, CAT-rapid for cognitive assessment, and Visual Analogue Scale (VAS) for non-adherence (the outcome). The data were analysed using both bivariate and multivariate regression analyses.

RESULTS

The participants' mean age (SD) was 17.7(1.60). The CIAs were more likely to have cognitive impairment (t -7.25; p < 0.01), while the BIAs had more depression (χ2 = 5.86; p = 0.016) and AUD (χ2 = 4.39; p = 0.036) and were more likely to be non-adherent (t = 3.14; p = 0.002). In the CIA group, cognitive impairment (AOR = 2.86; 95% CI:1.77-4.64) (AOR = 2.79; 95%CI:1.73-4.48) and depression (AOR = 2.69; 95%CI:1.48-4.90 were associated with ART non-adherence. In the BIA group, depression (AOR = 2.55; 95%CI:1.27-5.16), AUD (AOR = 2.58; 95%CI:1.21-5.49) and struggling to accept status (AOR = 2.54; 95%CI:1.41-4.56) predicted non-adherence to treatment.

CONCLUSION

The two groups of adolescents differ regarding ART non-adherence and associated psychosocial issues, indicating the need for differentiated care to address non-adherence in the ALWHIV, especially in high-burden, resource-constrained settings, such as Botswana.

A randomized stepped wedge trial of an intensive combination approach to roll back the HIV epidemic in Nigerian adolescents: iCARE Nigeria treatment support protocol

BACKGROUND

Nigeria is one of six countries with half the global burden of youth living with HIV. Interventions to date have been inadequate as AIDS-related deaths in Nigeria's youth have remained unchanged in recent years. The iCARE Nigeria HIV treatment support intervention, a combination of peer navigation and SMS text message medication reminders to promote viral suppression, demonstrated initial efficacy and feasibility in a pilot trial among youth living with HIV in Nigeria. This paper describes the study protocol for the large-scale trial of the intervention.

METHODS

The iCARE Nigeria-Treatment study is a randomized stepped wedge trial of a combination (peer navigation and text message reminder) intervention, delivered to youth over a period of 48 weeks to promote viral suppression. Youth receiving HIV treatment at six clinical sites in the North Central and South Western regions of Nigeria were recruited for participation. Eligibility criteria included registration as a patient at participating clinics, aged 15-24 years, on antiretroviral therapy for at least three months, ability to understand and read English, Hausa, Pidgin English, or Yoruba, and intent to remain a patient at the study site during the study period. The six clinic sites were divided into three clusters and randomized to a sequence of control and intervention periods for comparison. The primary outcome is plasma HIV-1 viral load suppression, defined as viral load ≤ 200 copies/mL, in the intervention period versus the control period at 48 weeks of intervention.

DISCUSSION

Evidence-based interventions to promote viral load suppression among youth in Nigeria are needed. This study will determine efficacy of a combination intervention (peer navigation and text message reminder) and collect data on potential implementation barriers and facilitators to inform scale-up if efficacy is confirmed.

The correlation between Th17/Treg immune dysregulation and the disease severity in chronic spontaneous urticaria patients

OBJECTIVE

Chronic spontaneous urticaria (CSU) has a profound impact on the sleep quality, productivity and overall quality of life of affected individuals. This study aimed to investigate the correlation between serum Th17/Treg immune dysregulation and the severity of CSU in patients.

METHODS

Clinical baseline data of 120 CSU patients and matched healthy controls were recorded. The pruritus level, disease severity, and quality of life of CSU patients were assessed using the visual analogue scale, weekly Urticaria Activity Score and chronic urticaria quality of life questionnaire, respectively. The Th17/Treg cell ratio was detected by flow cytometry. ELISA was used to measure the levels of serum Th17 cytokines (IL-17, IL-21) and Treg cytokines (TGF-β1, IL-35). Pearson's correlation analysis was conducted to examine the associations between these indicators.

RESULTS

No significant differences were identified in terms of sex, age, and BMI between the two groups. However, CSU patients exhibited a significant increase in the Th17 cell ratio, as well as the elevated serum levels of TGF-β1, IL-17 and, IL-21. Conversely, the proportion of Treg cells and the levels of IL-35 were remarkably decreased in CSU patients. Peripheral blood Th17 cells were negatively correlated with Treg cells. The severity of pruritus, life quality, and disease severity in CSU patients were positively correlated to Th17 cell ratio, and inversely correlated with Treg cell proportion.

CONCLUSIONS

A positive correlation was found between the percentage of peripheral blood Th17 cell in CSU patients and the pruritus level, life quality, and disease severity. In constrast, there was a negative correlation between the proportion of peripheral blood Treg cells and these clinical parameters.

Examining Recruitment Strategies in the Enrollment Cascade of Youth Living With HIV: Descriptive Findings From a Nationwide Web-Based Adherence Protocol

BACKGROUND

Digital strategies and broadened eligibility criteria may optimize the enrollment of youth living with HIV in mobile health adaptive interventions. Prior research suggests that digital recruitment strategies are more efficient than traditional methods for overcoming enrollment challenges of youth living with HIV in the United States.

OBJECTIVE

This study highlights the challenges and strategies that explain screening and enrollment milestones in a national web-based adherence protocol for youth living with HIV.

METHODS

Baseline data from a national web-based HIV adherence protocol for youth living with HIV, collected from July 2018 to February 2021, were analyzed. A centralized recruitment procedure was developed, which used web-based recruitment via Online Master Screener; paid targeted advertisements on social media platforms (eg, Facebook and Reddit) and geosocial networking dating apps (eg, Grindr and Jack'd); and site and provider referrals from Subject Recruitment Venues and other AIDS service organizations, website referrals, and text-in recruitment.

RESULTS

A total of 3 distinct cohorts of youth living with HIV were identified, marked by changes in recruitment strategies. Overall, 3270 individuals consented to screening, 2721 completed screening, 581 were eligible, and 83 completed enrollment. We examined sociodemographic and behavioral differences in completing milestones from eligibility to full enrollment (ie, submitting antiretroviral therapy and viral load data and completing the baseline web-based survey). Those with the most recent viral load tests >6 months ago were half as likely to enroll (odds ratio 0.45, 95% CI 0.21-0.94). Moreover, eligible participants with self-reported antiretroviral therapy adherence (SRA) between 50% and 80% were statistically significant (P<.001 to P=.03) and more likely to enroll than those with SRA >80%.

CONCLUSIONS

The findings add to our knowledge on the use of digital technologies for youth living with HIV before and during the COVID-19 pandemic and provide insight into the impact of expanding eligibility criteria on enrollment. As the COVID-19 pandemic continues and the use of and engagement with social media and dating apps among youth living with HIV changes, these platforms should continue to be investigated as potential recruitment tools. Using a wide variety of recruitment strategies such as using social media and dating apps as well as provider referral mechanisms, increasing compensation amounts, and including SRA in enrollment criteria should continue to be studied with respect to their ability to successfully recruit and enroll eligible participants.

Adherence to anti-retroviral therapy, decisional conflicts, and health-related quality of life among treatment-naïve individuals living with HIV: a DEARS-J observational study

BACKGROUND

Supporting people living with HIV using anti-retroviral therapy (ART) is important due to the requirement for strict medication adherence. To date, no data from longitudinal studies evaluating adherence by treatment-naïve people living with HIV are currently available. We investigated the adherence of treatment-naïve people living with HIV over time and examined the relationships among decisional conflicts, adherence, and health-related quality of life (HRQL).

METHODS

The survey items included adherence (visual analogue scale [VAS]), decisional conflict (decisional conflict scale [DCS]), and HRQL (Medical Outcomes Study HIV Health Survey [MOS-HIV]). The DCS and MOS-HIV scores and the VAS and MOS scores were collected electronically at the ART initiation time point and at 4-, 24-, and 48-week post-treatment time points.

RESULTS

A total of 215 participants were enrolled. The mean DCS score was 27.3 (SD, 0.9); 23.3% of participants were in the high-score and 36.7% in the low-score groups. The mean adherence rates at 4, 24, and 48 weeks were 99.2% (standard error [SE], 0.2), 98.4% (SE, 0.4), and 96.0% (SE, 1.2), respectively. The least-square means of the MOS-HIV for the DCS (high vs. low scores) were 64.4 vs. 69.2 for general health perceptions and 57.7 vs. 64.0 for HRQL, respectively.

CONCLUSION

Adherence among treatment-naïve people living with HIV was maintained at a higher level, and HRQL tended to improve with ART. People with high levels of decisional conflict tended to have lower HRQL scores. Support for people living with HIV during ART initiation may be related to HRQL.

Relationship Power, Antiretroviral Adherence, and Physical and Mental Health Among Women Living with HIV in Rural Kenya

Little is known about the association of gender-based power imbalances and health and health behaviors among women with HIV (WWH). We examined cross-sectional baseline data among WWH in a cluster-randomized control trial (NCT02815579) in rural Kenya. We assessed associations between the Sexual Relationship Power Scale (SRPS) and ART adherence, physical and mental health, adjusting for sociodemographic and social factors. SRPS consists of two subscales: relationship control (RC) and decision-making dominance. Women in the highest and middle tertiles for RC had a 7.49 point and 8.88 point greater Medical Outcomes Study-HIV mental health score, and a 0.27 and 0.29 lower odds of depression, respectively, compared to women in the lowest tertile. We did not find associations between SPRS or its subscales and ART adherence. Low sexual relationship power, specifically low RC, may be associated with poor mental health among WWH. Intervention studies aimed to improve RC among WWH should be studied to determine their effect on improving mental health.

The effectiveness of psychoeducation and problem-solving on depression and treatment adherence in adolescents living with HIV in Botswana: an exploratory clinical trial

BACKGROUND

This study aimed to explore the effectiveness of psychological interventions (PI): psychoeducation, problem-solving, and rehearsal strategies on depression and adherence in HIV-infected adolescents in Botswana.

METHODS

Fifty adolescents living with HIV were randomized into control (n = 25) and intervention groups (n = 25), the latter being exposed to five weeks of PI sessions. The PHQ-9 and visual analog scale (VAS) were used to measure the outcomes: depression and adherence at pre-intervention, 5- and 24 weeks post-intervention.

RESULTS

The participants' mean age (SD) was 17.38 years (1.1), the two groups being similar in socio-demographic variables: gender (χ² = 2.22; p = 0.135) and age (U = 285, z =  - 0.55, p = 0.579). The intervention group scored significantly lower on depressive symptoms (PHQ-9 [F (1,50) = 12.0, p = 0.001, ƞ_p² = 0.20]) and higher on adherence score (VAS [F (1,50) = 13.5, p = 0.001, ƞ_p² = 0.22]) than the control group after 5 weeks. The post-hoc analysis showed that the significant improvements in depressive symptoms (z =  - 4.03, p < 0.01, r [effect size] = 0.88) and adherence (z =  - 4.05, p < 0.01, r = 0.88) at post-test in the intervention group were maintained at 24 weeks. This project was registered with ClinicalTrials.gov (NCT05482217).

CONCLUSION

The 5-week PI showed promising effectiveness in addressing depression and adherence in adolescents living with HIV in Botswana.

Is self-reported adherence a valid measure of glycaemic control among people living with diabetes in rural India? A cross-sectional analysis

BACKGROUND

Visual analogue scale (VAS) is one of the simplest to measure medication adherence. It has neither been widely used for Non communicable diseases (NCD) nor validated for in the Indian setting. We examined the validity of self-reported medication adherence measures in relation to HbA1C in a rural population with diabetes mellitus (DM).

METHODS

Participants with DM was administered VAS, Diabetes Self-Management Questionnaire (DMSQ) and assessed for missed pills. Descriptive statistics and logistic regression analysis were done.

RESULTS

We recruited 1347 participants and 84% of them reported being 100% adherent as per VAS and 83.8% stated that they did not miss any pills. However, 58.2% of participants who reported having 100% adherence had poor glycaemic control, as did 58.1% of those who did not miss any pills. None of the diabetic self-care measures was significantly associated with glycaemic control.

CONCLUSION

We found a lack of association between self-reported adherence measures and glycaemic control in participants with DM suggesting that self-reported adherence scales may not be valid in this population.

Implementation of a Nurse-Delivered Cognitive Behavioral Therapy for Adherence and Depression of People Living with HIV in Korea

BACKGROUND

Cognitive behavioral therapy for adherence and depression (CBT-AD) performed by clinical psychologists is an effective treatment for improving the depression in people living with HIV (PLWH). However, because access to clinical psychologists is limited in most clinics, CBT-AD is rarely performed for PLWH in Korea. This pilot study evaluates whether CBT-AD can be effectively performed by a nurse trained and supervised by a clinical psychologist, with a view to the wider provision of CBT-AD.

MATERIALS AND METHODS

One clinical psychologist developed manuals, educated and supervised one nurse. PLWH with depression or adherence to self-reported antiretroviral therapy <90% were enrolled, and CBT-AD was conducted once weekly for 12 sessions. PLWH were assessed for adherence by visual analog scale, Beck depression inventory (BDI) for depression, PozQoL for quality of life, and Berger's 40-item stigma scale for stigma at baseline, after the 6th, 12th session, at 4-, and 8-months after CBT-AD. Acceptability for PLWH and feasibility for providers were evaluated through surveys.

RESULTS

Five male PLWH have completed the study protocols (mean age 29.2 years). All study participants showed improving depression (mean BDI at baseline 33.0 ± 7.0, and after the 12th session 13.4 ± 3.5), and the effect was maintained at the 8-month follow-up (BDI 15.4 ± 6.4). Quality of life showed a tendency to improve (mean PozQoL at baseline 28.0 ± 7.7, after 12th session 36.8 ± 4.4, and at the 8-month follow-up 38.2 ± 7.9), but stigma did not show clear improvement (Berger's 40-item stigma scale at baseline 121.0 ± 3.9, after 12th session 107.6 ± 8.8. and at the 8-month follow-up 107.6 ± 5.0). All study participants received great help from CBT-AD and expressed their desire to continue. All providers agreed that nurse-delivered CBT-AD could be implemented in routine clinical practice.

CONCLUSION

Our findings suggest that a nurse-delivered CBT-AD could be feasible and acceptable for PLWH through structured interventions. It has been shown to have the potential to help PLWH, especially for their depression and quality of life.

Comparing dedicated and designated approaches to integrating task-shared psychological interventions into chronic disease care in South Africa: a three-arm, cluster randomised, multicentre, open-label trial

BACKGROUND

Community health workers (CHWs) are increasingly providing task-shared psychological interventions for depression and alcohol use in primary health care in low-income and middle-income countries. We aimed to compare the effectiveness of CHWs dedicated to deliver care with CHWs designated to deliver care over and above their existing responsibilities and with treatment as usual for patients with a chronic physical disease.

METHODS

We did a three-arm, cluster randomised, multicentre, open-label trial done in 24 primary health-care clinics (clusters) within the Western Cape province of South Africa. Clinics were randomly assigned (1:1:1) to implement dedicated care, designated care, or treatment as usual, stratified by urban-rural status. Patients with HIV or type 1 or type 2 diabetes were eligible if they were 18 years old or older, taking antiretroviral therapy for HIV or medication to manage their diabetes, had an Alcohol Use Disorders Identification Test (AUDIT) score of eight or more or a Center for Epidemiologic Studies Depression Scale score of 16 or more, and were not receiving mental health treatment. In the intervention arms, all participants were offered three sessions of an evidence-based psychological intervention, based on motivational interviewing and problem-solving therapy, delivered by CHWs. Our primary outcomes were depression symptom severity and alcohol use severity, which we assessed separately for the intention-to-treat populations of people with HIV and people with diabetes cohorts and in a pooled cohort, at 12 months after enrolment. The Benjamini-Hochberg procedure was used to adjust for multiple testing. The trial was prospectively registered with the Pan African Clinical Trials Registry, PACTR201610001825403.

FINDINGS

Between May 1, 2017, and March 31, 2019, 1340 participants were recruited: 457 (34·1%) assigned to the dedicated group, 438 (32·7%) assigned to the designated group, and 445 (33·2%) assigned to the treatment as usual group. 1174 (87·6%) participants completed the 12 month assessment. Compared with treatment as usual, the dedicated group (people with HIV adjusted mean difference -5·02 [95% CI -7·51 to -2·54], p<0·0001; people with diabetes -4·20 [-6·68 to -1·72], p<0·0001) and designated group (people with HIV -6·38 [-8·89 to -3·88], p<0·0001; people with diabetes -4·80 [-7·21 to -2·39], p<0·0001) showed greater improvement on depression scores at 12 months. By contrast, reductions in AUDIT scores were similar across study groups, with no intervention effects noted.

INTERPRETATION

The dedicated and designated approaches to delivering CHW-led psychological interventions were equally effective for reducing depression, but enhancements are required to support alcohol reduction. This trial extends evidence for CHW-delivered psychological interventions, offering insights into how different delivery approaches affect patient outcomes.

A Systematic Review of Digital Interventions to Improve ART Adherence among Youth Living with HIV in sub-Saharan Africa

An estimated 3.4 million youth aged 15-24 years live with human immunodeficiency virus (HIV), a majority of whom reside in sub-Saharan Africa (SSA). Youth living with HIV (YLHIV) generally maintain lower levels of antiretroviral therapy (ART) adherence compared to other age groups, which has negative impacts on long-term clinical outcomes. Given expanding mobile phone and Internet usage among youth in SSA, and a need for strategies to increase ART adherence, this review systematically assessed whether digital interventions could be used to improve YLHIV ART adherence in SSA. PRISMA 2020 guidelines were followed, and PubMed and Scopus databases were searched using terms to reflect the population of interest and different digital intervention strategies to improve ART adherence. Experimental or quasi-experimental studies in SSA evaluating the quantitative effect of digital interventions on YLHIV ART adherence were included. 3849 articles and abstracts, and 122 full texts were screened by two researchers (KG and RM). A third researcher (AC) resolved conflicts. Data were extracted from six eligible articles published between 2017 and 2021. Interventions from included studies lasted 13-96 weeks and took place in Kenya, Nigeria, Uganda, and Zimbabwe. Two of the six studies found significant intervention-related improvements in viral suppression. Of these two studies, one used short message service (SMS) for appointment and daily adherence reminders, and the other combined weekly SMS reminders with phone calls, support groups, home visits, and clinic-based counseling. The four remaining studies, using SMS and Internet-based interventions, did not find any significant adherence-related improvements. This review provides mixed evidence for using digital interventions to improve ART adherence among YLHIV in SSA. Given the relative novelty of using digital interventions in this context, further research is required to evaluate their effectiveness in improving youth ART adherence.

Nonadherence by Serum Drug Analyses in Resistant Hypertension: 7-Year Follow-Up of Patients Considered Adherent by Directly Observed Therapy

Background Measurement of serum concentrations of drugs is a novelty found useful in detecting poor drug adherence in patients taking ≥2 antihypertensive agents. Regarding patients with treatment-resistant hypertension, we previously based our assessment on directly observed therapy. The present study aimed to investigate whether serum drug measurements in patients with resistant hypertension offer additional information regarding drug adherence, beyond that of initial assessment with directly observed therapy. Methods and Results Nineteen patients assumed to have true treatment-resistant hypertension and adherence to antihypertensive drugs based on directly observed therapy were investigated repeatedly through 7 years. Serum concentrations of antihypertensive drugs were measured by ultra-high-performance liquid chromatography-tandem mass spectrometry from blood samples taken at baseline, 6-month, 3-year, and 7-year visits. Cytochrome P450 polymorphisms, self-reported adherence and beliefs about medicine were performed as supplement investigations. Seven patients (37%) were redefined as nonadherent based on their serum concentrations during follow-up. All patients reported high adherence to medications. Nonadherent patients expressed lower necessity and higher concerns regarding intake of antihypertensive medication (P=0.003). Cytochrome P450 polymorphisms affecting metabolism of antihypertensive drugs were found in 16 patients (84%), 21% were poor metabolizers, and none were ultra-rapid metabolizers. Six of 7 patients redefined as nonadherent had cytochrome P450 polymorphisms, however, not explaining the low serum drug concentrations measured in these patients. Conclusions Our data suggest that repeated measurements of serum concentrations of antihypertensive drugs revealed nonadherence in one-third of patients previously evaluated as adherent and treatment resistant by directly observed therapy, thereby improving the accuracy of adherence evaluation.

Efficacy of a Telehealth Delivered Couples' HIV Counseling and Testing (CHTC) Intervention to Improve Formation and Adherence to Safer Sexual Agreements Among Male Couples in the US: Results from a Randomized Control Trial

This paper reports the results of a randomized controlled trial (RCT) to assess the efficacy of Nexus, a telehealth delivered intervention that combines Couples' HIV counseling and testing (CHTC) with home-based HIV-testing, examining the impact of the intervention on the couples' formation and adherence to safer sexual agreements. Between 2016 and 2018, 424 couples were recruited online from the U.S and randomized to the intervention arm (a telehealth delivered CHTC session with two home HIV-testing kits) or a control arm (two home HIV-testing kits), with study assessments at baseline, 3 and 6 months. Outcomes were the formation and adherence to safer sexual agreements, dyadic discordance in sexual agreements, breakage of sexual agreements, and perceptions of PrEP. Couples in the intervention arm had significantly greater odds of reporting a safer sexual agreement (3 months OR 1.87, p-value 0.005, and 6 months OR 1.84, p-value 0.007), lower odds of reporting discordant sexual agreements at 6 months (OR 0.62, p-value 0.048), and a significantly lower odds of reporting breaking their sexual agreement (3 months OR 0.51, p-value 0.035, and 6 months OR 0.23, p-value 0.000). By 6 months, couples in the intervention arm were less likely to say PrEP was beneficial to one (RRR 0.33, P = 0.000) or both of them (RRR 0.29, P = 0.000) than being beneficial to neither of the partners. The high levels of acceptability and efficacy of the intervention demonstrate strong potential for the scale-up of this efficacious intervention that is delivered through a low-cost telehealth platform.

Believing That It Is Hazardous to Mix Alcohol With Medicines Predicts Intentional Nonadherence to Antiretrovirals

BACKGROUND

Drinking alcohol is a robust predictor of medication nonadherence. In addition to the impact of intoxication on adherence, individuals who believe that it is hazardous to mix medications with alcohol (ie, interactive toxicity beliefs) may forgo taking their medications when drinking. Previous research suggests that alcohol-related intentional nonadherence is a direct result of interactive toxicity beliefs. This study prospectively tested the association between alcohol interactive toxicity beliefs and intentional nonadherence to HIV treatment [ie, antiretroviral therapy (ART)].

METHODS

Four hundred eight people living with HIV completed comprehensive baseline assessments and 15-month attributions for ART nonadherence.

RESULTS

One in 5 participants reported foregoing taking their ART when drinking out of concern for hazardous mixing of alcohol and ART. Poisson regression models predicting the number of months that participants were intentionally nonadherent to ART because they were drinking was predicted by alcohol-ART interactive toxicity beliefs.

CONCLUSIONS

Beliefs that it is hazardous to drink alcohol when taking medications explains intentional nonadherence and should be directly addressed in adherence improvement interventions for people living with HIV who drink alcohol.

A skills-based sero-status HIV disclosure intervention for sexual minority men in South Africa: A protocol for intervention adaptation and pilot randomized controlled trial (Preprint)

Background

Gay, bisexual, and other men who have sex with men (GBMSM) living with HIV have low antiretroviral treatment adherence in South Africa due to limited skills in managing disclosure and prevention behaviors with sexual and romantic partners. As a result, there is a high HIV transmission risk within HIV-discordant partnerships, but an existing intervention may address these outcomes, if adapted effectively. Healthy Relationships (HR) is a behavioral intervention that was originally delivered in groups and in person over 5 sessions to develop coping skills for managing HIV-related stress and sexually risky situations, enhance decision-making skills for HIV disclosure to partners, and establish and maintain safer sex practices with partners. HR effectively improves prevention behaviors but has yet to be tailored to a non-US context.

Objective

We aim to adapt HR into a new culturally grounded intervention entitled Speaking Out & Allying Relationships for GBMSM and then assess its feasibility in Eastern Cape, South Africa.

Methods

The study will have 2 aims. For aim 1—adaptation—we will use a human-centered design approach. Initial intervention tailoring will involve integrating Undetectable=Untransmittable and pre-exposure prophylaxis education, developing intervention content for a videoconference format, and designing role-plays and movies for skill building based on preliminary data. Afterward, interviews and surveys will be administered to GBMSM to assess intervention preferences, and a focus group will be conducted with health care providers and information technology experts to assess the intervention’s design. Finally, a usability test will be performed to determine functionality and content understanding. Participants will be GBMSM living with HIV (n=15) who are in a relationship and health care providers and information technology (n=7) experts working in HIV care and programming with this population. For aim 2, we will examine the feasibility of the adapted intervention by using a pilot randomized control design. There will be 60 individuals per arm. Feasibility surveys and interviews will be conducted with the intervention arm, and behavioral and biomedical assessments for relationship and treatment adherence outcomes will be collected for both arms. All participants will be GBMSM living with HIV who are in a relationship with an HIV-negative or unknown status partner.

Results

Intervention adaptation began in August 2021. Initial tailoring and the refining of GBMSM intervention preferences were completed in December 2021. Usability and feasibility assessments are due to be completed by March 2022 and February 2024, respectively.

Conclusions

GBMSM need efficacious interventions that tackle partnership dynamics, HIV prevention, and treatment outcomes for antiretroviral treatment adherence and viral suppression in South Africa. Harnessing everyday technology use for social networking (eg, videoconferences), Undetectable=Untransmittable education, and pre-exposure prophylaxis to update an existing intervention for South African GBMSM has the potential to strengthen relationship communication about HIV treatment and prevention and, in turn, improve outcomes.

Adherence monitoring methods to measure virological failure in people living with HIV on long-term antiretroviral therapy in Uganda

Appointment keeping and self-report within 7-day or and 30-days recall periods are non-objective measures of antiretroviral treatment (ART) adherence. We assessed incidence of virological failure (VF), predictive performance and associations of these adherence measures with VF among adults on long-term ART. Data for persons initiated on ART between April 2004 and April 2005, enrolled in a long-term ART cohort at 10-years on ART (baseline) and followed until December 2021 was analyzed. VF was defined as two consecutives viral loads ≥1000 copies/ml at least within 3-months after enhanced adherence counselling. We estimated VF incidence using Kaplan-Meier and Cox-proportional hazards regression for associations between each adherence measure (analyzed as time-dependent annual values) and VF. The predictive performance of appointment keeping and self-reporting for identifying VF was assessed using receiver operating characteristic curves and reported as area under the curve (AUC). We included 900 of 1,000 participants without VF at baseline: median age was 47 years (Interquartile range: 41-51), 60% were women and 88% were virally suppressed. ART adherence was ≥95% for all three adherence measures. Twenty-one VF cases were observed with an incidence rate of 4.37 per 1000 person-years and incidence risk of 2.4% (95% CI: 1.6%-3.7%) over the 5-years of follow-up. Only 30-day self-report measure was associated with lower risk of VF, adjusted hazard ratio (aHR) = 0.14, 95% CI:0.05-0.37). Baseline CD4 count ≥200cells/ml was associated with lower VF for all adherence measures. The 30-day self-report measure demonstrated the highest predictive performance for VF (AUC = 0.751) compared to appointment keeping (AUC = 0.674), and 7-day self-report (AUC = 0.687). The incidence of virological failure in this study cohort was low. Whilst 30- day self-report was predictive, appointment keeping and 7-day self-reported adherence measures had low predictive performance in identifying VF. Viral load monitoring remains the gold standard for adherence monitoring and confirming HIV treatment response.

Assessing the Prevalence of Diabetes Distress and Determining Its Psychosocial Predictors Among Saudi Adults With Type 2 Diabetes: A Cross-Sectional Study

In recent years, the global burden of diabetes distress has increased significantly worldwide, imposing mental health issues on patients and the healthcare system. Hence, this study aimed to estimate the prevalence of diabetes distress and determine its psychosocial predictors among Saudi adults with type 2 diabetes mellitus (T2DM). This cross-sectional, observational study was conducted at Diabetes Clinics, Tertiary Care Academic Medical Center, King Saud University Medical City, Riyadh, Saudi Arabia. The survey questionnaire was distributed to 423 participants. The sample size was 384, where the prevalence of diabetes distress was 48.5%. Based on 5% precision and a confidence interval of 95%, the response rate was 78.25% (334 respondents), among which 61.4% of respondents were females, the remaining 38.6% were males, and the mean age was 56.39 years. The mean scores for the Saudi Arabian Diabetes Distress Scale-17 (SADDS-17) subdomains including emotional burden, physician-related distress, regimen-related distress, and interpersonal distress were 2.63 ± 1.29, 2.31 ± 1.44, 2.48 ± 1.16, and 2.23 ± 1.24, respectively. Based on the World Health Organization Quality of Life Assessment Instrument, Short Version (WHOQOL-BREF) transformed scores, the quality of life was recorded as 62.7%. There was a statistically significant positive correlation between the Hospital Anxiety and Depression Scale (HADS) score (r = 0.287, p < 0.01) and the total SADDS-17 scores. The Patient Health Questionaire (PHQ) 15 scores showed significant positive correlations with the total SADDS-17 scores (r = 0.288, p < 0.01) and each of the four subdomains. Our present study revealed that diabetes distress prevalence is alarmingly high among patients in Saudi Arabia, Riyadh. Our findings provide evidence that physical symptoms, quality of life, depression, and anxiety are the notable predictors of diabetes distress.

Subjective well-being and COVID-19 prevention practices among people living with HIV in Cape Town, South Africa

COVID-19 poses significant threats to the health of people with underlying chronic conditions, including people living with HIV. The association between subjective well-being and practicing COVID-19 preventive behaviours among people living with HIV is yet to be empirically tested. The objective of the current study was to test the hypothesis that subjective well-being would be associated with engaging in greater COVID-19 preventive behaviours. A sample of 200 women and 72 men (mean age 38.1, SD = 10.4) receiving HIV treatment at a clinic in Cape Town, South Africa completed interview administered surveys of health behaviours and three dimensions of subjective well-being: emotional, social and psychological well-being. Hierarchical regression models were performed to test subjective well-being as predictors of COVID-19 preventive behaviours adjusting for age, sex, education, TB history, antiretroviral therapy adherence, and concern about contracting COVID-19. Results showed that psychological well-being, along with concerns over COVID-19, predicted greater COVID-19 preventive behaviours over and above the other variables in the model, accounting for 9.2% of the variance. Results support incorporating interventions to foster psychological well-being into existing clinical services for people living with HIV to improve clusters of health behaviours.

Walking and perceived lack of safety: Correlates and association with health outcomes for people living with HIV in rural Zambia

INTRODUCTION

Geographic inaccessibility disproportionately affects health outcomes of rural populations due to lack of suitable transport, prolonged travel time, and poverty. Rural patients are left with few transport options to travel to a health facility. One common option is to travel by foot, which may present additional challenges, such as perceived lack of safety while transiting. We examined the correlates of perceived lack of safety when walking to a health facility and its association with treatment and psychosocial outcomes among adults living with HIV.

METHODS

Data were collected from 101 adults living with HIV in Eastern Province, Zambia. All participants were receiving antiretroviral therapy at one of two health clinics. Perceived lack of safety was measured by asking respondents whether they felt unsafe traveling to and from the health facility in which they were receiving their HIV care. Outcomes included medication adherence, perceived stress, hope for the future, and barriers to pill taking. Linear and logistic regression methods were used to examine the correlates of perceived safety and its association with health outcomes.

RESULTS

Being older, a woman, having a primary education, living farther from a health facility, traveling longer to reach a health facility, and owing money were associated with higher likelihood of feeling unsafe when traveling by foot to health facility. Perceived lack of safety was associated with medication nonadherence, higher level of stress, lower level of agency, and more barriers to pill taking.

CONCLUSIONS

Perceived lack of safety when traveling by foot to a health facility may be a barrier to better treatment and psychosocial outcomes, especially among rural patients. Practitioners and policymakers should consider implementation of differentiated HIV service delivery models to reduce frequent travel to health facilities and to alleviate ART patients' worry about lack of safety when traveling by foot to a health facility.

Stronger Together: Results from a Randomized Controlled Efficacy Trial of a Dyadic Intervention to Improve Engagement in HIV Care Among Serodiscordant Male Couples in Three US Cities

Engagement in HIV care and a high level of antiretroviral therapy (ART) adherence for people living with HIV is crucial to treatment success and can minimize the population burden of the disease. Despite this, there is a critical gap in HIV prevention science around the development of interventions for serodiscordant male couples. This paper reports on the results of a randomized controlled trial to assess the efficacy of Stronger Together, a dyadic counseling intervention aimed at increasing engagement in and optimizing HIV care among serodiscordant male couples in Atlanta, GA, Boston, MA, and Chicago, IL. Between 2014 and 2017, 159 male serodiscordant couples (total N = 318) in Atlanta, GA, Boston, MA, and Chicago, IL were enrolled and equally randomized to either the Stronger Together intervention arm (a three-session dyadic intervention involving HIV testing and adherence counseling) or a standard of care (SOC) control arm. Couples completed individual study assessments via an audio computer assisted self-interviewing (ACASI) system at baseline, 6, 12 and 18 months. Primary outcomes included being prescribed and currently taking ART, and fewer missed doses of ART in the past 30 days; because the trial was not powered to examine viral suppression, we examined this as an exploratory outcome. Longitudinal data analysis was by an intention-to-treat approach. Participants ages ranged from 18 to 69 (mean = 35.9), and are predominantly white (77.5%), and college educated (68.4% earned a college degree or higher). Participants randomized to the Stronger Together arm had a significantly greater odds of being prescribed and currently taking ART over time than those in the SOC arm (at 12 months OR 2.75, 95%CI 1.35-4.67, p-value 0.020, and at 18 months OR 2.91, 95%CI 1.61-4.88, p-value 0.013). Similarly, those in the Stronger Together arm had a significantly lower odds of missing a dose of ART in the past 30 days over time compared to those in the SOC arm (at 12 months OR 0.28, 95%CI 0.09-0.81, p-value 0.019, and at 18 months OR 0.25, 95%CI 0.07-0.82, p-value 0.023). Among male couples in serodiscordant relationships, the Stronger Together intervention resulted in significantly improved HIV treatment outcomes at both 12 and 18 months of follow-up. This trial is the first to date to demonstrate evidence of efficacy for a dyadic counseling intervention and has the potential to fill a critical gap in secondary HIV prevention interventions for serodiscordant male couples.

Effect of Text Messaging Plus Peer Navigation on Viral Suppression Among Youth With HIV in the iCARE Nigeria Pilot Study

BACKGROUND

Consistent with the global trend, youth with HIV (YWH) in Nigeria have high rates of viral nonsuppression. Hence, novel interventions are needed.

SETTING

Infectious Diseases Institute, College of Medicine, University of Ibadan, Nigeria.

METHODS

In a single-arm trial, participants aged 15-24 years received 48 weeks of a combination intervention, comprising daily 2-way text message medication reminders plus peer navigation. The primary outcome measure was viral suppression less than 200 copies/mL. The secondary outcome measures included self-reported adherence on a visual analog scale and medication possession ratio, each dichotomized as ≥90% (good) or <90% (poor) adherence. The outcomes were analyzed using McNemar test. Retention in care, intervention feasibility and acceptability, and participants' satisfaction were also assessed.

RESULTS

Forty YWH (50% male participants) were enrolled: mean age 19.9 years (SD = 2.5), 55% perinatally infected, and 35% virologically suppressed at baseline. Compared with baseline, the odds of virologic suppression was higher at 24 weeks (odds ratio = 14.00, P < 0.001) and 48 weeks (odds ratio = 6.00, P = 0.013). Self-reported adherence (≥90%) increased from baseline at 24 weeks (63%, P = 0.008) and 48 weeks (68%, P = 0.031). Medication possession ratio ≥90% increased at weeks 24 and 48 (85% and 80%, respectively), achieving statistical significance at 24 weeks alone (P = 0.022). Retention in care at 48 weeks was 87.5%. All (37/37) participants at week 48 were fully or mostly satisfied with the intervention.

CONCLUSION

Daily 2-way text message reminders plus peer navigation is a promising combination intervention to improve viral suppression among YWH in Nigeria.

Patient-reported outcomes for HIV: the future of long-acting injectables and antiretroviral therapy evaluations

Patient-reported outcomes (PROs) are an increasingly important aspect of patient care, as they offer a perspective from the patient themselves in the treatment and management of a particular disease state. They have a potential role in helping clinicians select an appropriate drug regimen in human immunodeficiency virus-1 (HIV-1)-infected individuals, as well as those with HIV/hepatitis C (HCV) co-infection. They can also provide insight for individuals receiving long-acting (LA) injectable antiretroviral therapy (ART). Studies found from PROs that participants on an LA injectable ART regimen reported greater preference and treatment satisfaction compared with those on an oral ART regimen. Some additional studies have also used PROs to evaluate the switch to single-tablet regimens and compare different ART in treating HIV-1. Current PROs and how they can be improved for LA injectables were also discussed.

Perceived sensitivity to medicines and the experience of side-effects: understanding intentional medication nonadherence among people living with HIV

Patient initiated decisions to forgo taking medications (i.e. intentional nonadherence) pose significant challenges to managing chronic health conditions. Identifying factors and their underlying mechanisms that impede medication adherence is essential to designing treatment improvement interventions. This study tested a conceptual model that posits the effects of perceived sensitivity to medicines on adherence can be explained by the experience of side-effects, leading to intentionally nonadherent behaviors. Patients receiving HIV care in the southern United States (N = 209) completed measures of perceived sensitivity to medicines, antiretroviral therapy (ART) side-effects, intentional nonadherence and overall adherence. Patients also provided consent to access their electronic medical records to collect subsequent reports of HIV viral load tests. Results indicated that more than one in four participants were intentionally nonadherent to ART. Mediation modeling showed that perceived sensitivity to medicines was associated with greater experience of ART side-effects and intentional nonadherence, which impacted overall ART adherence and HIV viral load. There were also significant indirect effects of perceived sensitivity to medicines on HIV viral load through side-effects and intentional nonadherence. Patients with increased perceived sensitivity to medicines are at risk for poor treatment outcomes and these negative outcomes are partly explained by experiencing greater side-effects and intentional nonadherence.

HIV Testing, Knowledge and Willingness to Use PrEP Among Partnered Men Who Have Sex With Men in South Africa and Namibia

There is strong evidence that gay, bisexual and other men who have sex with men (GBMSM) in African countries experience high prevalence of HIV. However, missing from the literature is an understanding of the HIV risk behaviors and prevention needs of partnered GBMSM in African countries. The Together Tomorrow project sampled 440 partnered GBMSM (220 couples) in South Africa and Namibia. Prevalence of HIV was high at 42%, with 33% of men in sero-discordant relationships. Despite high levels of HIV testing in the past 6 months (65%), condom use with main and outside sex partners was low. Men reported low levels of willingness to use pre-exposure prophylaxis (PrEP) (16%). HIV testing in the past 12 months and willingness to use PrEP were significantly associated with recent binge drinking and substance use. Men in sero-discordant relationships, those with sexual agreements and those who had experienced any form of IPV were all less likely to report that they had recently tested for HIV. There is a need to develop interventions that meet the unique needs of African partnered GBMSM and tackle stigma and discrimination as drivers of HIV risk in these settings.

Defining the optimal cut-point of self-reported ART adherence to achieve viral suppression in the era of contemporary HIV therapy: a cross-sectional study

BACKGROUND

When considering adherence to antiretroviral therapy (ART) for HIV, many different cut-points are used. The primary goals of this study were to identify a level of self-reported medication adherence that best distinguished HIV viral suppression from non-suppression, and to compare the ability of a single-item and a 3-item adherence questionnaire to predict HIV viral suppression.

METHODS

This cross-sectional analysis included 380 persons with HIV (PWH) from the Florida Cohort study who completed a self-reported ART adherence measure within 30-days of having an HIV viral load test. We used Receiver Operating Characteristic (ROC) curve analyses and ROCContrast to compare the ability of a single-item and a 3-item self-reported adherence measure to predict HIV viral suppression (defined as ≤ 200 copies/mL). We used the Youden index and chi square statistics to assess specific cut-points, and repeated the analysis with a different definition of HIV viral suppression (≤ 1000 copies/mL).

RESULTS

The mean percent adherence was 92.4% using the single-item score and 90.4% using the 3-item score; 81.6% had viral suppression. The areas under the curve for the single-item and 3-item adherence measures were generally poor overall and not significantly different from each other (0.589 and 0.580, p = 0.67). The Youden index identified cut-points of 93% and 89% as maximizing the sensitivity and specificity for the single-item and 3-item measures, respectively, whereas a cut-point of 80% on the single-item measure was best able to discriminate those with viral suppression (58% vs. 84%, p < 0.001). Results were similar with viral suppression defined as ≤ 1000 copies/mL.

CONCLUSIONS

In this sample of PWH, a single question on medication adherence was as good as a 3-item questionnaire in predicting HIV viral suppression, although neither had good discriminatory ability. A cut-point close to 90% adherence maximized sensitivity and specificity, although viral suppression was very similar for nearly all measures above 80%.

Intimate partner violence is a barrier to antiretroviral therapy adherence among HIV-positive women: Evidence from government facilities in Kenya

INTRODUCTION

Intimate Partner Violence (IPV) is linked to low engagement with HIV management services and adverse clinical outcomes, including poor ART adherence. In sub-Saharan Africa, studies on pregnant/postpartum women and transactional sex workers have produced divergent evidence regarding IPV's association with poor ART adherence. We investigate this association among a broad group of women.

METHODS

We sampled 408 HIV-positive women receiving free ART from different types of HIV clinics at government health facilities, assessing for IPV exposure by a current partner, ART adherence rate, and other factors that affect ART adherence (e.g. education, disclosure). ART adherence rates were measured using the Visual Analogue Scale (VAS); responses were dichotomised at a ≥95% cut-off. Multiple logistic regression models assessed the association between the independent variables and ART adherence.

RESULTS

The participants' mean age was 38.6 (range: 18-69 years). The majority had ever attended school (94%, n = 382), were in monogamous marriages (70%, n = 282), and had disclosed status to partners (94%, n = 380). Overall, 60% (n = 242) reported optimal ART adherence (≥ 95%) in the previous 30 days. The prevalence of IPV by the current partner was 76% (CI95 = 72-80%). Experiencing physical IPV (AOR 0.57, CI95: 0.34-0.94, p = .028), sexual IPV (AOR 0.50, CI95: 0.31-0.82, p = .005), or controlling behaviour (AOR 0.56, CI95: 0.34-0.94, p = .027) reduced the odds of achieving optimal adherence, while a higher education level and having an HIV-positive partner increased the odds.

CONCLUSION

IPV is common and is associated with suboptimal ART adherence rates among a broad group of HIV-positive women. ART programs could consider incorporating basic IPV interventions into regular clinic services to identify, monitor and support exposed women, as they might be at risk of poor ART adherence. Still, there is need for more research on how IPV affects ART adherence.

A Single-Blind, Parallel Design RCT to Assess the Effectiveness of SMS Reminders in Improving ART Adherence Among Adolescents Living with HIV (STARTA Trial)

PURPOSE

The study evaluated the feasibility, acceptability, and efficacy of interactive and tailored short message reminders on antiretroviral therapy adherence among adolescents (15-19 years) living with HIV in southwest Nigeria.

METHODS

The study was a single-blind, parallel-design (ratio 1:1), and multicenter RCT of 209 medication-non-adherent adolescents living with HIV at HIV clinics in two states in southwest Nigeria. The research assessed ART adherence using the visual analog scale, viral suppression, pill count, and ACTG scores; the feasibility of the intervention by the SMS delivery and response (overall and individual) rates; and acceptability using self-report, willingness to continue receiving the intervention, and desire for its scale-up.

RESULTS

A total of 17,690 text messages were sent while 10,119 (57.2%) got delivered to the participants. Out of 9,216 responses that were received from the study participants, 8,781 (95.3%) indicated acceptability of the intervention. The end-of-study log₁₀ of viral load values between control and intervention groups had a mean difference of 0.66 (95% CI 0.26-1.06) and p-value of .001. Also, the unadjusted odds ratio of undetected viral load (≤20 copies/ml) was 1.356 (1.039-1.771) with a p-value of .002. However, the intervention had no effect on subjective measures of antiretroviral therapy adherence.

CONCLUSIONS

The use of interactive and tailored short message reminders to enhance antiretroviral therapy adherence among adolescents has good potential. It seems feasible, highly acceptable, and possibly leads to improved viral load count. It is likely that the associated antiretroviral therapy adherence enhances viral suppression and, therefore, improves outcomes in adolescent HIV.

Brief Enhanced Partner Notification and Risk Reduction Counseling to Prevent Sexually Transmitted Infections, Cape Town, South Africa

BACKGROUND

Evidence-based interventions are needed to stem sexually transmitted infections (STIs). Clinic-delivered counseling remains an important avenue for effective STI prevention.

METHODS

A 3-arm randomized clinical trial compared (a) STI health education control condition, (b) risk reduction counseling, and (c) enhanced partner notification counseling. Men and women (n = 1050) were recruited from an STI clinic in Cape Town, South Africa. After baseline assessments, participants were randomly allocated to receive 1 of the 3 single-session counseling interventions and were followed up for 9 months of behavioral assessments and 12 months of electronic medical records abstraction for STI clinic services.

RESULTS

Sexual risk reduction counseling reported greater condom use than did the other 2 conditions during the 3 and 6 months follow-ups. In addition, women receiving risk reduction counseling were significantly less likely to have returned for STI clinic services but did not differ in the number of STI clinic visits over the year.

CONCLUSIONS

Brief single-session STI prevention counseling demonstrates significant targeted outcomes. The findings suggest that counseling approaches to both increase condom use and enhance partner notification may offer more robust and sustained outcomes and should be tested in future research.

Gender Affirmation through Correct Pronoun Usage: Development and Validation of the Transgender Women's Importance of Pronouns (TW-IP) Scale

Social interactions where a person is addressed by their correct name and pronouns, consistent with their gender identity, are widely recognized as a basic and yet critical aspect of gender affirmation for transgender people. Informed by the Model of Gender Affirmation, we developed a self-report measure of the importance of social gender affirmation, the Transgender Women's Importance of Pronouns (TW-IP) scale, which measures gender affirmation through the usage of correct pronoun by others. Data were from self-administered surveys in two independent samples of transgender women living with HIV in the US (N1 = 278; N2 = 369). Using exploratory factor analysis with data from Study 1 and confirmatory factor analysis with data from Study 2, we obtained a four-item scale with a single-factor structure and strong reliability (α = 0.95). We present evidence of TW-IP's convergent and discriminant validity through its correlations with select mental health and HIV-related measures. Further, scores on TW-IP were linked in expected directions to several hypothesized mental health and HIV care outcomes, demonstrating its predictive validity. The resulting brief measure of importance of pronouns among transgender women shows strong psychometric properties. Validation evidence offers highly promising opportunities for use of the measure in clinical and research settings.

Neurocognitive Functioning is Associated with Self-Reported and Performance-Based Treatment Management Abilities in People Living with HIV with Low Health Literacy

OBJECTIVE

People living with HIV (PLWH) are at higher risk for poorer neurocognitive functioning and health literacy than uninfected persons, which are associated with worse medical outcomes. Aging research suggests that the effect of neurocognitive functioning on health outcomes may be more pronounced in those with low health literacy. We aimed to determine whether low health literacy might amplify the adverse effects of neurocognitive functioning on treatment management outcomes in 171 PLWH aged 40+.

METHOD

In this cross-sectional, observational study, participants completed a well-validated battery of neurocognitive, health literacy, and treatment management measures. A binary health literacy variable (low vs. adequate) was determined via established cut points on the well-validated health literacy tests. Treatment management outcomes included biomarkers of HIV (i.e., CD4 counts and viral load), self-management of HIV disease (i.e., self-reported medication adherence and self-efficacy for HIV disease management), and performance-based health-related decision-making.

RESULTS

Forty-seven percent of the sample met the criteria for low health literacy. Multivariable regressions adjusting for clinicodemographic (e.g., race, socioeconomic status) covariates revealed significant interactions for self-efficacy for HIV disease management and health-related decision-making, such that neurocognitive functioning was associated with these outcomes among those with low, but not adequate health literacy.

CONCLUSIONS

Findings suggest that low health literacy may increase the vulnerability of PLWH to the adverse effects of neurocognitive impairment on health outcomes, or conversely that adequate health literacy may provide a buffer against the health risks associated neurocognitive impairment. Interventions targeting health literacy in PLWH may mitigate the effects of neurocognitive impairment on health outcomes.

One-Way and Two-Way Mobile Phone Text Messages for Treatment Adherence Among Patients With HIV: Protocol for a Randomized Controlled Trial

Background

Incomplete adherence to antiretroviral therapy (ART) is one of the factors that contribute to HIV drug resistance, and it is a major problem for the public health system in controlling the HIV pandemic. There is emerging evidence that SMS can play an important role in health care delivery among patients with HIV on ART, especially in resource-limited settings.

Objective

This paper aims to assess the impact of two-way and one-way SMS text messaging on adherence to HIV treatment. We hypothesized that sending weekly text messages through the one-way and two-way SMS text messaging approach will improve adherence to ART among patients with HIV and improve associated clinical outcomes (quality of life).

Methods

A randomized controlled trial is being carried out among participants with HIV who have been on ART for at least one month from an accredited treatment center, namely the Buea Regional Hospital and Kumba District Hospital of South West Region, Cameroon. Participants with HIV, both male and female, aged 21 years and older make up a sample size of 207. The interventions involved the use of mobile phone text messages. Before commencing the intervention, a focus group discussion was carried out among the participants to understand their perception about the use of SMS-based interventions to improve adherence. A total of 246 participants were randomized to receive either a one-way text message (SMS sent to a recipient without recipient sending a reply) or two-way text message (SMS sent to a recipient and recipient sends a reply) or the control (no SMS, only standard care). Data on adherence and quality of life were collected at baseline and after 6 months and will be analyzed using SPSS version 21, while qualitative data will be analyzed using Atlas.ti 7.5.

Results

Data collection began in September 2019 with focus group discussions and baseline data collection. After 1 month of baseline data collection, the intervention began in October 2019, and postintervention data were collected after 6 months (March 2020). At the end of the study, we will be able to understand the perception of patients toward SMS text messaging–based interventions and also assess the impact of one-way and two-way SMS text messages on treatment adherence among patients with HIV and on associated clinical outcomes (quality of life).

Conclusions

The impact of SMS text messaging varies across different settings. The results from this study will determine the perception of patients toward an SMS text messaging–based intervention and its impact on adherence to ART.

HIV Status Disclosure and Sexual Transmission Risks Among People Who Are Living With HIV and Receiving Treatment for Non-HIV Sexually Transmitted Infections, Cape Town, South Africa

BACKGROUND

HIV status disclosure to sex partners potentially reduces the risk of sexually transmitting HIV. However, there is limited information on the associations between HIV status disclosure in types of sexual partnerships and ensuing sexual practices.

METHODS

We examined HIV status disclosure to sex partners among 205 men and women living with HIV and receiving diagnostic and treatment services for a co-occurring sexually transmitted infection (STI) in Cape Town, South Africa. Participants completed partner-by-partner sexual behavior interviews and provided permission to extract recurrent STI clinic visits over the subsequent 12 months.

RESULTS

Three groups were formed on the basis of HIV status disclosure to sex partners: (1) 22% reported only HIV same-status partners, (2) 26% had HIV-negative or unknown HIV status (HIV different status) sex partners to whom they had disclosed their HIV status, and (3) 52% had at least one HIV different-status partner to whom they had not disclosed. There were no associations between HIV status disclosure and demographic characteristics, sexual practices, or recurrent STI clinic visits. Undisclosed HIV status to at least one HIV different-status sex partner was associated with greater alcohol use and less likelihood of receiving antiretroviral therapy; participants who were least likely to disclose their HIV status to partners drank more alcohol and were less likely to be taking antiretroviral therapy.

CONCLUSIONS

High prevalence of partner nondisclosure and lack of significant correlates to HIV status disclosure indicate a need for further research with an eye toward identifying disclosure processes and mechanisms that may ultimately lead to effective interventions.

Magnitude of non-adherence to antiretroviral therapy and associated factors among adult people living with HIV/AIDS in Benishangul-Gumuz Regional State, Ethiopia

Introduction

Following global efforts to increase antiretroviral therapy (ART) access and coverage, Ethiopia has made significant achievement with a 6.3% annual decline in the HIV/AIDS incidence rate between 1990 and 2016. Such success depends not only on access to ART but also on attaining optimum treatment adherence. Emerging studies in Ethiopia has shown the increasing prevalence of poor adherence and lack of the desired viral suppression, but the extent and factors associated with non-adherence to ART are not well known, especially in the current study setup. In this study, we examined the magnitude and factors associated with treatment and non-adherence to ART among people living with HIV in Benishangul-Gumuz Regional State, northwest Ethiopia.

Methods

An institutional facility based cross-sectional descriptive study was carried out among adult people living with HIV/AIDS from mid-December 2016 to February 2017 with only 98.9% response rate. Sociodemographic factors (age, gender, marital status and residential area), economic factors (educational status, income, asset possession, employment status, dietary diversity, nutritional status and food security), and clinical characteristics (CD4 count, duration on ART and history of opportunistic infections) were explanatory variables. ART non-adherence was measured using a visual analogue scale (VAS). We used binary logistic regression and subsequent multivariate logistic regression analysis to determine the factors associated with ART non-adherence.

Result

Overall, 39.7% of the participants were found non-adherent to ART. Strong association was found between non-adherence to ART and young age below 25 years (AOR: 4.30, 95% CI [1.39-3.35]; p = 0.011), urban residential area (AOR: 2.78, CI [1.23-7.09], p = 0.043), lack of employment (AOR: 1.75, 95% CI [1.05-2.91], p = 0.032), food insecurity (AOR: 2.67, 95% CI [7.59-8.97]; p < 0.0001), malnutrition (AOR: 1.55, 95% CI [1.94-2.56]; p = 0.027) and opportunistic infections (AOR: 1.81, 95% CI [1.11-2.97]; p = 0.018).

Conclusion

The prevalence of non-adherence to ART in this study was high. Sociodemographic and economic factors such as young age of below 25 years, urban residential area, lack of employment, food insecurity, malnutrition and opportunistic infections were among the factors associated with non-adherence to ART.

Alcohol-Related Intentional Antiretroviral Nonadherence among People Living with HIV: Test of an Interactive Toxicity Beliefs Process Model

Beliefs that it is harmful to mix medications with alcohol (ie, interactive toxicity beliefs) are a known source of intentional antiretroviral therapy (ART) nonadherence. This study examined a serial process model of alcohol-ART interactive toxicity beliefs, alcohol-ART avoidance behaviors, and ART adherence in the association between alcohol use and HIV viral load. Participants were 198 patients receiving ART from a community clinic in the southeastern United States; 125 reported current alcohol use. Results showed that current alcohol use was associated with detectable HIV viral load, partially accounted for by alcohol-ART interactive toxicity beliefs, alcohol-ART avoidance behaviors, and ART adherence. There was a significant indirect effect of the serial chain of interactive toxicity beliefs-avoidance behaviors-adherence, indicating the 3 intermediating variables partially accounted for the relationship between alcohol use and HIV viral load. Addressing alcohol use as a barrier to ART adherence requires multipronged approaches that address intentional nonadherence.

Treatment Adherence Among Persons Receiving Concurrent Multidrug-Resistant Tuberculosis and HIV Treatment in KwaZulu-Natal, South Africa

BACKGROUND

Success in multidrug-resistant tuberculosis (MDR-TB) and HIV treatment requires high medication adherence despite high pill burdens, frequent adverse events, and long treatment duration, which may jeopardize adherence. We prospectively compared MDR-TB/HIV-coinfected persons to those with MDR-TB alone to determine the impact of concurrent treatment on adherence and outcomes.

METHODS

We assessed medication adherence monthly using 3-day recall, 30-day recall, and visual analog scale and examined adherence to monthly study visits (months 0-12). We determined the proportion of participants fully adherent (no reported missed doses) to MDR-TB vs. HIV treatment by each measure. We assessed the association of medication and clinic visit adherence with MDR-TB treatment success (cure or completion, 18-24 months) and HIV virologic suppression.

RESULTS

Among 200 patients with MDR-TB, 63% were women, median age was 33 years, 144 (72%) were HIV-infected, and 81% were receiving antiretroviral therapy (ART) at baseline. Adherence to medications (81%-98% fully adherent across all measures) and clinic visits (80% missed ≤1 visit) was high, irrespective of HIV status. Adherence to ART was significantly higher than to MDR-TB treatment by all self-reported measures (3-day recall: 92% vs. 84%, respectively; P = 0.003). In multivariable analysis, the adjusted risk ratio of unsuccessful MDR-TB treatment increased with every missed visit: 1.50, 2.25, and 3.37 for unsuccessful treatment, for 1, 2, and ≥3 missed visits.

CONCLUSIONS

Adherence to ART was higher than to MDR-TB treatment among persons with MDR-TB/HIV coinfection. Missed clinic visits may be a simple measure for identifying patients at risk of unsuccessful MDR-TB treatment outcome.

Peritransition Outcomes of Southeast Asian Adolescents and Young Adults With HIV Transferring From Pediatric to Adult Care

PURPOSE

The aim of this article was to study the clinical and social outcomes of health care transition among Asian adolescents and young adults with HIV (AYHIV).

METHODS

AYHIV who transferred from a pediatric to an adult clinic within the past year across five sites in Malaysia, Thailand, and Vietnam had clinical and laboratory evaluations and completed questionnaires about their health, socioeconomic factors, and transition experiences. Multiple logistic regression was used to assess associations with HIV viremia.

RESULTS

Of 93 AYHIV enrolled between June 2016 and April 2017, 56% were female, 87% acquired HIV through perinatal exposure, median age was 20 years (interquartile range [IQR] 18.5-21). Two-thirds were in a formal education program, 43% were employed, 43% of females and 35% of males were sexually active. Median lifetime antiretroviral therapy duration was 6.2 years (IQR 3.3-10.7); 45% had received second-line therapy. Median CD4 was 601 cells/mm³ (IQR 477-800); 82% had HIV-RNA <40 copies/mL. Being in a relationship, a shorter posttransition duration, self-reported adherence of ≥95%, and higher CD4 were inversely associated with HIV viremia. Half felt very prepared for the transfer to adult care, and 20% frequently and 43% sometimes still met with pediatric providers. Two-thirds reported needing to keep their HIV a secret, and 23%-38% reported never or rarely having someone to discuss problems with.

CONCLUSIONS

Asian AYHIV in our cohort were concerned about the negative social impact of having and disclosing HIV, and one-third lacked people they could trust with their personal problems, which could have negative implications for their ability to navigate adult life.

Impact of Medication Regimen Simplification on Medication Adherence and Clinical Outcomes in Patients with Long-Term Medical Conditions

BACKGROUND

This study aims to identify interventions used to reduce medication regimen complexity and to assess their impact on medication adherence and clinical outcomes.

METHODS

A literature search was conducted using pre-defined search terms in three scientific databases, including ScienceDirect, ProQuest and MEDLINE. Original research articles published in English between 2009 and 2020 that assessed the impact of medication regimen simplification on medication adherence in patients with long-term medical conditions were eligible for inclusion. Review articles, meta-analysis studies and conference proceedings were excluded. Data charting was done in an iterative process using a study-specific extraction form.

RESULTS

Of the 684 studies identified through initial searches, 17 studies were included in the review. Nine studies involved simplification of medication regimen related to HIV, while three studies focused on patients with diabetes with or without coronary artery disease. The remaining five studies included medications used among elderly patients or medications related to hypertension, psychiatric disorders, glaucoma and kidney diseases. Three medication regimen simplification strategies were identified; fixed-dose combination (n = 7), once-daily dosing (n = 4) and the combination of both fixed-dose and once-daily dosing (n = 6). Overall, most of the regimen simplification strategies (14 out of 17) were found to be useful in improving medication adherence. There was no assessment of clinical outcomes in four out of 17 studies. Furthermore, more than half of the studies that assessed clinical outcomes did not show any additional impact on clinical outcomes.

CONCLUSION

The findings suggest that there was an equal utilization of the three main approaches of regimen simplifications; fixed-dose combination, once-daily dosing and a combination of both. Overall, most of the regimen simplification strategies were found to be effective in improving medication adherence. However, the associated improvement in medication adherence did not extend to improvement in the clinical outcomes.
