Socioeconomic status and treatment outcomes for individuals with HIV on antiretroviral treatment in the UK: cross-sectional and longitudinal analyses

High Prevalence of Posttraumatic Stress Disorder Symptoms Found in Well-Treated People with HIV after the Introduction of Patient-Reported Outcome Measures

People with HIV (PWH) are at greater risk of experiencing mental health problems, such as depression and post-traumatic stress disorder (PTSD). The purpose of our study was to determine the prevalence of posttraumatic stress disorder PTSD in PWH. PWH in care Amsterdam University Medical center (Amsterdam UMC) with access to the electronic patient portal were offered patient-reported outcome measures (PROMs) between May 2022 and May 2023, including the PC-PTSD-5 screen for PTSD as part of routine clinical care. Risk factors for a clinically relevant PC-PTSD-5 score were determined using univariate and multiple logistic regression analyses. Of 2476 PWH included, 1384 (55.9%) had access to the electronic patient portal of whom 474 (34.2%) completed the PC-PTSD-5. PWH without access to the patient portal were more often female, born in low- and middle-income countries, acquired HIV more often via heterosexual contact, and had worse HIV-related outcomes compared to those with access. Of 474 PWH who completed the PC-PTSD-5 screening question, 62 (13.1%) reached the threshold for clinically relevant PTSD. Age less than 50 years (OR 2.29, 95% CI: 1.21-4.35), and having originated from low- or middle-income countries (OR 2.02, 95% CI: 1.09-3.76) were associated with PTSD. Our findings show that 13% of PWH with a well-controlled HIV infection with access to the electronic patient portal at Amsterdam UMC experienced clinically relevant PTSD complaints.

Employment Status and HIV Viral Load in Chilean Adult Population: A Propensity Score Analysis

We set out to investigate the potential impact of unemployment on HIV viral load in individuals living with HIV at the biggest HIV-related healthcare centre in Chile. We analysed a cross-sectional dataset of 803 adults living with HIV on antiretroviral therapy. The main exposure was employment status. The outcome, detectable HIV viral load, was operationalised using a cut-off of HIV viral load at 20 copies/mL. We applied a propensity score method, the inverse probability of treatment weighting to control for measured confounders. We found that 219 (27.3%) of participants were unemployed. Being unemployed was associated with increased odds of being detectable (OR = 1.78, 95%CI = 1.18-2.71) compared to being employed. Additionally, we found that those unemployed and non-adherents have higher odds of being detectable (OR = 2.53, 95%CI = 1.18-5.41). Unemployment status may influence HIV viral load. However, further research is needed to determine and understand the social structure behind those relationships in the Chilean people living with HIV.

"How well do we know our patients?": Further validation of a complexity rating scale for HIV

BACKGROUND

Despite advances in the management and treatment of HIV, identifying risks for disengagement are essential to maximize positive outcomes. The current study investigated the validity of the Clinical Complexity Rating Scale for HIV (CCRS-HIV), a risk-prediction tool, by assessing agreement between patient and clinician scores of patient complexity.

METHODS

207 patients completed the patient version of the CCRS-HIV (CCRS-HIVP), and six Attending Medical Officers (AMOs) caring for those individuals completed the original clinician version (CCRS-HIVC). Kappa statistics, sensitivity and specificity were used to assess patient-clinician agreement.

RESULTS

Patient-clinician agreement was highest for problematic crystal methamphetamine use (86%), polypharmacy (84%) and other physical health concerns (67%). Cut-offs of 40 and 45 for the total CCRS-HIV score were identified as most appropriate, with high sensitivity (79.31% and 76.0% respectively).

CONCLUSIONS

Overall agreement between the clinician and patient complexity scores was high. These findings provide further evidence of the validity of the scale. The study demonstrates that the unique role of AMOs at the center contributes to them knowing their patients well, allowing them to manage and refer when required for interdisciplinary care which likely contributes to their ongoing engagement in care and may account for the high level of agreement.

The Contribution of Socioeconomic Factors to HIV RNA Suppression in Persons With HIV Engaged in Care in the NA-ACCORD

INTRODUCTION

Socioeconomic status (SES) influences well-being among people living with HIV (people with HIV [PWH]); when individual-level SES information is not available, area-level SES indicators may be a suitable alternative. We hypothesized that (1) select ZIP code-level SES indicators would be associated with viral suppression and (2) accounting for ZIP code-level SES would attenuate racial disparities in viral suppression among PWH.

SETTING

The NA-ACCORD, a collaboration of clinical and interval cohorts of PWH, was used.

METHODS

Participants with ≥1 viral load measurement and ≥1 US residential 5-digit ZIP code(s) between 2010 and 2018 were included. In this serial cross-sectional analysis, multivariable logistic regression models were used to quantify the annual association of race and ethnicity with viral suppression, in the presence of SES indicators and sex, hepatitis C status, and age.

RESULTS

We observed a dose-response relationship between SES factors and viral suppression. Lower income and education were associated with 0.5-0.7-fold annual decreases in odds of viral suppression. We observed racial disparities of approximately 40% decreased odds of viral suppression among non-Hispanic Black compared with non-Hispanic White participants. The disparity persisted but narrowed by 3%-4% when including SES in the models.

CONCLUSIONS

ZIP code-based SES was associated with viral suppression, and accounting for SES narrowed racial disparities in viral suppression among PWH in the NA-ACCORD. Inclusion of ZIP code-level indicators of SES as surrogates for individual-level SES should be considered to improve our understanding of the impact of social determinants of health and racial disparities on key outcomes among PWH in North America.

How can HIV self-testing facilitate increased access to HIV testing among multiply marginalised populations? Perspectives from GBMSM and trans women in England and Wales

BACKGROUND

HIV self-testing (HIVST) may facilitate marginalised populations' uptake of HIV testing, but whether the extent of marginalisation challenges individual uptake of HIVST remains under-researched. We aim to explore the perspectives of multiply marginalised cis-gender gay, bisexual and other men who have sex with men (GBMSM) and trans women on whether HIVST might increase their uptake of HIV testing.

METHODS

We reanalysed qualitative interview data from SELPHI (the UK's largest HIVST randomised trial) collected between 2017 and 2020 from marginalised populations, defined as people self-identifying as non-heterosexual, transgender, non-White ethnicity and/or with low educational attainment. Thirty-eight interviews with multiply marginalised individuals were thematically examined using the framework method. We specifically focussed on kit usability (a function of the interaction between blood-based HIVST kits and users), perspectives on how HIVST can improve access to HIV testing and suggestions on need-based scale-up of HIVST.

RESULTS

HIVST kits were considered usable and acceptable by multiply marginalised GBMSM and trans women. The majority of interviewees highlighted multi-levelled barriers to accessing HIV testing services due to structural and social marginalisation. Their multiply marginalised identities did not impede HIVST uptake but often form motivation to self-test. Three potential roles of HIVST in the HIV testing landscape were identified: (1) alternation of HIVST and facility-based testing, (2) integration of HIVST into sexual health services and (3) substituting facility-based testing with HIVST in the future. Perceived beneficiaries of HIVST included trans communities, individuals with undisclosed sexuality and people with physical disabilities.

DISCUSSION

HIVST can facilitate marginalised populations' access and uptake of HIV testing by alternating with, integrating into and substituting for facility-based services in the UK. Marginalised identities did not present challenges but rather opportunities for person-centred scale-up of HIVST. Future implementation programmes should ensure equitable access to HIVST among trans people, men unable to disclose their sexuality, and perhaps people with physical disabilities.

Factors associated with antiretroviral treatment adherence among people living with HIV in Guangdong Province, China: a cross sectional analysis

BACKGROUND

Understanding factors associated with antiretroviral treatment (ART) adherence is crucial for ART success among people living with HIV (PLHIV) in the "test and treat" era. Multiple psychosocial factors tend to coexist and have a syndemic effect on ART adherence. We aimed to explore factors associated with ART adherence and the syndemic effect of multiple psychosocial factors on ART adherence among PLHIV newly starting ART in Guangdong Province, China.

METHODS

Newly diagnosed PLHIV from six cities in Guangdong Province were recruited between May 2018 and June 2019, and then followed up from May 2019 to August 2020. Baseline and follow-up data were collected from a questionnaire and the national HIV surveillance system, the follow-up data of which were analyzed in this study. A Center for Adherence Support Evaluation (CASE) index > 10 points was defined as optimal ART adherence, which was measured via participants' self-reported adherence during follow-up survey. Multivariable logistic regression was used to identify factors associated with ART adherence. Exploratory factor analysis (EFA) and multi-order latent variable structural equation modeling (SEM) were performed to explore the syndemic effect of multiple psychosocial factors on ART adherence.

RESULTS

A total of 734 (68.53%) follow-up participants were finally included in this study among the 1071 baseline participants, of whom 91.28% (670/734) had self-reported optimal ART adherence. Unemployment (aOR = 1.75, 95%CI: 1.01-3.02), no medication reminder (aOR = 2.28, 95%CI: 1.09-4.74), low medication self-efficacy (aOR = 2.28, 95%CI: 1.27-4.10), low social cohesion (aOR = 1.82, 95%CI: 1.03-3.19), no social participation (aOR = 5.65, 95%CI: 1.71-18.63), and ART side effects (aOR = 0.46, 95%CI: 0.26-0.81) were barriers to optimal ART adherence. The EFA and second-order latent variable SEM showed a linear relationship (standardized coefficient = 0.43, P < 0.001) between ART adherence and the latent psychosocial (syndemic) factor, which consisted of the three latent factors of medication beliefs and self-efficacy (standardized coefficient = 0.65, P < 0.001), supportive environment (standardized coefficient = 0.50, P < 0.001), and negative emotions (standardized coefficient=-0.38, P < 0.01). The latent factors of medication beliefs and self-efficacy, supportive environment, and negative emotions explained 42.3%, 25.3%, and 14.1% of the variance in the latent psychosocial factor, respectively.

CONCLUSIONS

About nine out of ten PLHIV on ART in Guangdong Province self-reported optimal ART adherence. However, more efforts should be made to address barriers to optimal ART adherence.

Latent Constructs of Economic Marginality Associated with Sexual Behavior, Healthcare Access and HIV Outcomes Among Transgender and Nonbinary People in Three U.S. Cities

Transgender and nonbinary people (TNB) in the U.S. experience high HIV prevalence and diverse economic hardships. Yet a comprehensive understanding of how multiple, simultaneously occurring hardships-termed economic marginality-are together associated with healthcare and HIV outcomes is needed. Leveraging survey data from a sample of 330 TNB people in three U.S. cities, we conducted an exploratory mixed-source principal component analysis of latent factors of economic experience, then estimated their associations with sexual behavior, access to healthcare, HIV status, and HIV testing frequency. Two factors emerged: a traditional socioeconomic factor related to income, education, and employment (SES), and one related to housing precarity and (lack of) assets (Precarity). Higher Precarity scores were associated with sexual behavior, cost-based healthcare avoidance, discrimination-based healthcare avoidance, and more frequent HIV testing. Findings highlight the importance of understanding profiles of economic marginalization among trans and nonbinary people and can inform efforts to address upstream, structural factors shaping healthcare access and HIV outcomes in this key population.

Sociodemographic and health systems determinants of antiretroviral therapy adherence among human immunodeficiency virus-positive patients in the Volta Region of Ghana: A multi-centre study

Objectives

Optimal adherence to antiretroviral therapy is required for viral load suppression. This study investigated the sociodemographic (age, sex, marital status, level of education, monthly income, settlement type, distance to the antiretroviral therapy-providing site, ethnicity) and health system (antiretroviral therapy-providing site) determinants of antiretroviral therapy adherence among human immunodeficiency virus-positive patients in the Volta Region, Ghana.

Methods

A cross-section design was adopted, collecting data from 1729 human immunodeficiency virus patients and analysing them using STATA version 17 at level 0.05.

Results

Antiretroviral therapy adherence was poor (51.2%). Being divorced (Adjusted odds ratio (AOR) = 0.65), widow (AOR = 0.58), cohabiting (AOR = 0.22), Ewe (AOR = 3.7), Ga/Dangbe (AOR = 2.27), living in a rural area (AOR = 1.54) and an urban area (AOR = 0.64), having a monthly income of GH₵1000 or less (AOR = 3.21), covering a distance of 51 km and above to the antiretroviral therapy centre (AOR = 1.79), receiving antiretroviral therapy from Ketu South Municipal Hospital (AOR = 0.09), Hohoe Municipal Hospital (AOR = 0.03), Ho Municipal Hospital (AOR = 0.02) and Ho Teaching Hospital (AOR = 0.09) were the determinants of antiretroviral therapy adherence.

Conclusion

Antiretroviral therapy adherence was low. Interventions to improve antiretroviral therapy adherence should target these significant determinants.

The Positive Impact of Foods Support on Loss to Follow Up Among Children and Adolescents on HIV Antiretroviral Therapy in a District Hospital in East Cameroon

Introduction

The pediatric HIV treatment coverage in Cameroon remains low at 35%. The high loss to follow up (LTFU) remains a major factor to this dismal performance which is related to the lack of implementation of effective interventions to improve retention in care. This study assessed the impact of foods support (FS) on LTFU among children and adolescents in a rural district hospital in eastern Cameroon.

Methods

This was a retro-prospective study conducted in Abong Mbang District Hospital (ADH) in the East Region of Cameroon. We provided foods kits to children and adolescents initiated on antiretroviral therapy (ART) in this facility during the study and followed them up prospectively (prospective phase). On the other hand, using medical records, we collected retrospectively data for children and adolescents who enrolled on ART in the hospital prior to the study (retrospective phase). We then compared the proportions of children and adolescents LTFU before (no FS) and after (with FS) the study, using the Fisher's exact test, logistic regression, Kaplan-Meier survival curves and Cox proportional-hazards model at 5% significant level.

Results

We found that with FS, the proportion of children and adolescents LTFU was 11 times lower (2.4% vs 26.7%, p=0.014), the mean time of retention in care was 30% higher (17 months vs 12 months, p<0.001) and children and adolescents who did not receive FS were 10 times more likely to be LTFU [aHR=10.3 (4.0-26.2), p<0.001)].

Conclusion

Foods support is an effective intervention in reducing LTFU among children and adolescents on ART. This intervention should be adequately funded to enable a large-scale implementation in the field. This could help to improve the outcome of pediatric ART coverage in resource-limited settings.

All-cause hospitalisation among people living with HIV according to gender, mode of HIV acquisition, ethnicity, and geographical origin in Europe and North America: findings from the ART-CC cohort collaboration

BACKGROUND

Understanding demographic disparities in hospitalisation is crucial for the identification of vulnerable populations, interventions, and resource planning.

METHODS

Data were from the Antiretroviral Therapy Cohort Collaboration (ART-CC) on people living with HIV in Europe and North America, followed up between January, 2007 and December, 2020. We investigated differences in all-cause hospitalisation according to gender and mode of HIV acquisition, ethnicity, and combined geographical origin and ethnicity, in people living with HIV on modern combination antiretroviral therapy (cART). Analyses were performed separately for European and North American cohorts. Hospitalisation rates were assessed using negative binomial multilevel regression, adjusted for age, time since cART intitiaion, and calendar year.

FINDINGS

Among 23 594 people living with HIV in Europe and 9612 in North America, hospitalisation rates per 100 person-years were 16·2 (95% CI 16·0-16·4) and 13·1 (12·8-13·5). Compared with gay, bisexual, and other men who have sex with men, rates were higher for heterosexual men and women, and much higher for men and women who acquired HIV through injection drug use (adjusted incidence rate ratios ranged from 1·2 to 2·5 in Europe and from 1·2 to 3·3 in North America). In both regions, individuals with geographical origin other than the region of study generally had lower hospitalisation rates compared with those with geographical origin of the study country. In North America, Indigenous people and Black or African American individuals had higher rates than White individuals (adjusted incidence rate ratios 1·9 and 1·2), whereas Asian and Hispanic people living with HIV had somewhat lower rates. In Europe there was a lower rate in Asian individuals compared with White individuals.

INTERPRETATION

Substantial disparities exist in all-cause hospitalisation between demographic groups of people living with HIV in the current cART era in high-income settings, highlighting the need for targeted support.

Cognitive impairment in people living with HIV: consensus recommendations for a new approach

Current approaches to classifying cognitive impairment in people living with HIV can overestimate disease burden and lead to ambiguity around disease mechanisms. The 2007 criteria for HIV-associated neurocognitive disorders (HAND), sometimes called the Frascati criteria, can falsely classify over 20% of cognitively healthy individuals as having cognitive impairment. Minimum criteria for HAND are met on the basis of performance on cognitive tests alone, which might not be appropriate for populations with diverse educational and socioeconomic backgrounds. Imprecise phenotyping of cognitive impairment can limit mechanistic research, biomarker discovery and treatment trials. Importantly, overestimation of cognitive impairment carries the risk of creating fear among people living with HIV and worsening stigma and discrimination towards these individuals. To address this issue, we established the International HIV-Cognition Working Group, which is globally representative and involves the community of people living with HIV. We reached consensus on six recommendations towards a new approach for diagnosis and classification of cognitive impairment in people living with HIV, intended to focus discussion and debate going forward. We propose the conceptual separation of HIV-associated brain injury - including active or pretreatment legacy damage - from other causes of brain injury occurring in people living with HIV. We suggest moving away from a quantitative neuropsychological approach towards an emphasis on clinical context. Our recommendations are intended to better represent the changing profile of cognitive impairment in people living with HIV in diverse global settings and to provide a clearer framework of classification for clinical management and research studies.

The long-term impact of HIV/AIDS on socio-economic status: a comparative analysis of households headed by HIV-positive and HIV-negative individuals in Western Kenya

HIV/AIDS is known to have adverse effects on individual and family socio-economic status due to the loss of productive time and over-expenditure in treatment. However, empirical data on how HIV/AIDS affects households' socio-economic status are insufficient. We linked socio-economic data from a Health and Demographic Surveillance System (HDSS) that implements an HIV/AIDS Longitudinal bio-behavioural survey (LBBS) to understand the long-term impact of HIV/AIDS on households' socio-economic status between 2010 and 2018. We compared changes in socio-economic status between households headed by HIV-negative and -positive individuals. A logistic regression was used to assess factors that influence socio-economic status. The level of education and household size were not significant predictors of households' socio-economic status. Households headed by HIV-positive individuals could maintain their baseline socio-economic status (unadjusted RRR = 1.17, 95% CI: 1.01, 1.36) but improvement chances were reduced despite a non-significant association (unadjusted RRR = 0.98, 95% CI: 0.80, 1.20). While HIV/AIDS is known to disrupt economic growth, in this setting, being a male household head, old and widowed reduces chances of improved socio-economic status. The elderly people, widows and widowers are disadvantaged. Consequently, there is a need for special programmes, which seek to empower the identified vulnerable groups economically. .

Changing co-morbidity and increasing deprivation among people living with HIV: UK population-based cross-sectional study

BACKGROUND

The great success of HIV treatments means that, increasingly, people living with HIV (PLHIV) are growing old enough to develop age-associated comorbid conditions. We investigated the evolution of comorbid conditions and demographics among PLHIV in England.

METHODS

In a cross-sectional study linking Clinical Practice Research Datalink (CPRD) primary care, hospitalization, death registry and Index of Multiple Deprivation data, we measured the prevalence of 304 individual health conditions, categorized into 47 condition groups (36 non-communicable, 11 communicable). Using logistic regression, we calculated odds ratios (ORs) for the likelihood of each condition and condition group in 2015 versus 2008, adjusting for age, sex and deprivation.

RESULTS

In 2015, there were 964 CPRD-registered PLHIV compared with 1987 in 2008; 62% were male and 38% female in both cohorts. The 2015 cohort was older, with 51.1% aged 45-64 years and 7.2% aged 65-84 years compared with 31.8% and 3.2%, respectively, in 2008. Deprivation was higher in 2015, at 23.9% (quintile 4) and 28.7% (quintile 5) compared with 5.8% and 6.6%, respectively, in 2008. Of 36 non-communicable condition groups, 14 (39%) occurred in ≥ 10% of PLHIV in 2015, of which seven were more likely in 2015 than in 2008: renal-chronic-kidney-disease [odds ratio (OR) = 1.96 (95% CI: 1.33-2.90); endocrine-obesity [OR = 1.76 (1.12-2.77)]; rheumatology [OR = 1.64 (1.30-2.07)]; dermatology [OR = 1.55(1.29-1.85)]; genito-urinary-gynaecological [OR = 1.44(1.18-1.76)]; eyes-ears/nose/throat [OR = 1.31(1.08-1.59)]; and gastro-intestinal conditions [OR = 1.28 (1.04-1.58)]. Two condition groups, respiratory-chronic-obstructive-pulmonary-disease [OR = 0.36 (0.19-0.69)] and endocrine-diabetes [OR = 0.49 (0.34-0.70)], were less likely in 2015. Ten out of 11 communicable infectious condition groups were less likely in 2015.

CONCLUSIONS

Although infections in PLHIV have fallen, chronic non-communicable comorbidity is increasingly prevalent. Alongside the marked increases in deprivation and ageing, this study suggests that socio-economic measures in addition to healthcare provision are needed to achieve holistic health for PLHIV.

Determinants of Successful Human Immunodeficiency Virus Treatment Outcomes: A Linkage of National Data Sources in Malaysia

Background

Concerted efforts have been undertaken to reduce the human immunodeficiency virus (HIV) infection by the year 2030 in Malaysia. A situational analysis of the performance of successful HIV treatment and its determinants is vital; however, this information remains scarce. This study aimed to identify the determinants of undetectable viral load among people living with HIV (PLHIV).

Methods

Newly diagnosed HIV cases (n = 493) registered under the Malaysia HIV/AIDS-related national databases from June 2018 to December 2019 were studied. The deterministic matching method was applied to link the records in two national databases (at Kuala Lumpur and Putrajaya Federal Territories Health Department, JKWPKLP HIV line-listing database and National AIDS Registry). Successful HIV treatment, an outcome variable, was measured by the undetectable viral load < 200 copies/mL after 1 year of antiretroviral therapy initiation. Logistic regression analysis was applied in the current study.

Results

Results showed that 454/493 (92.2%; 95% confidence interval [CI]: 89.8%, 94.6%) PLHIV had successful HIV treatment. Study participants had a mean (SD) age of 30 (8.10) years old, predominantly male (96.1%) and sexually transmission (99.9%). The multiple logistic regression analysis revealed two significant determinants including the timing of ART initiation (AOR = 3.94; 95% CI: 1.32, 11.70; P = 0.014) and establishment of Sexually Transmitted Infection Friendly Clinic (STIFC) (AOR = 3.40; 95% CI: 1.47, 7.85; P = 0.004). Non-significant variables included gender, education level, HIV risk exposure, and co-infections of tuberculosis and Hepatitis C.

Conclusion

JKWPKLP is on the right track to achieving universal treatment as a prevention strategy. Reinforcement of early ART initiation and establishment of STIFC are recommended.

Cognitive performance in a South African cohort of people with HIV and comorbid major depressive disorder

Cognitive performance in people with HIV (PWH) may be affected by brain injury attributable to the infection itself, by other medical and psychiatric comorbidities (including major depressive disorder; MDD), and by psychosocial factors (e.g., education, food insecurity). We investigated effects of these variables on cognitive performance in a South African cohort of PWH with comorbid MDD and incomplete adherence to antiretroviral therapy (ART). We also examined (a) associations of depression severity with cognitive performance, and (b) whether improvement in depression led to improved cognitive performance. Participants (N = 105) completed baseline neuropsychological, psychiatric, and sociodemographic assessments. Subsequently, 33 were assigned to a cognitive-behavioural therapy for ART adherence and depression (CBT-AD) and 72 to standard-of-care treatment. Eight months post-baseline, 81 (nCBT-AD = 29) repeated the assessments. We investigated (a) baseline associations between sociodemographic, medical, and psychiatric variables and cognitive performance, (b) whether, from baseline to follow-up, depression and cognitive performance improved significantly more in CBT-AD participants, and (c) associations between post-intervention improvements in depression and cognitive performance. At baseline, less education (β = 0.62) and greater food insecurity (β = -0.20) predicted poorer overall cognitive performance; more severe depression predicted impairment in the attention/working memory domain only (β = -0.25). From baseline to follow-up, depression decreased significantly more in CBT-AD participants (p = .017). Improvement over time in depression and cognitive performance was not significantly associated except in the attention/working memory domain (p = .026). Overall, factors associated with cognitive performance were unrelated to brain injury. We conclude that clinicians examining PWH presenting with cognitive difficulties must assess depression, and that researchers investigating cognitive impairment in PWH must collect information on psychosocial factors.

Knowledge of viral load, PrEP, and HIV-related sexual risk among men who have sex with men in the Waterloo region

Gay, bisexual, and other men who have sex with men (GBMSM) remain most disproportionately affected by HIV in Canada. HIV-related sexual risk behaviours have been linked to high HIV risk among GBMSM, but prior research has not focused on knowledge of viral load, and the risk it presents for HIV acquisition. The purpose of this study was to explore the relationship between HIV-related sexual risk behaviour and knowledge of viral load among GBMSM. A cross-sectional survey was conducted using a convenience sample of individuals age 16 and older who self-identified as LGBTQ and lived, worked, or resided in the Waterloo region, an urban-rural area in southwestern Ontario ( N = 526). Responses were analyzed from those identifying as GBMSM ( N = 269). Logistic regression models were created to explore sociodemographic, outness, social support, and HIV-related sexual risk variables associated with knowledge of viral load. Multivariable regression models were built to explore the same associations while controlling for confounders. HIV risk was not associated with knowledge of viral load in bivariate or multivariable analyses. Point estimates for low/negligible (odds ratio [OR] 1.10; 95% CI 0.46–2.51) and high risk (OR 1.88; 95% CI 0.68–5.20) suggest trends of higher knowledge with increased HIV risk. Men who engage in sexual risk behaviour may have increased sexual health literacy and awareness of biomedical interventions (e.g., pre-exposure prophylaxis, or PrEP) that reduce HIV risk. Policies are needed that promote acceptance of sexual orientation, improve awareness and access to PrEP, and ensure optimal delivery of HIV education to at-risk groups prior to engagement in higher risk activities.

Incorporating social determinants of health into the mathematical modeling of HIV/AIDS

Currently, it is estimated that 37.6 million people are living with the HIV/AIDS virus worldwide, placing HIV/AIDS among the ten leading causes of death, mostly among low- and lower-middle-income countries. Despite the effective intervention in the prevention and treatment, this reduction did not occur equally among populations, subpopulations and geographic regions. This difference in the occurrence of the disease is associated with the social determinants of health (SDH), which could affect the transmission and maintenance of HIV. With the recognition of the importance of SDH in HIV transmission, the development of mathematical models that incorporate these determinants could increase the accuracy and robustness of the modeling. This article aims to propose a theoretical and conceptual way of including SDH in the mathematical modeling of HIV/AIDS. The theoretical mathematical model with the Social Determinants of Health has been developed in stages. For the selection of SDH that were incorporated into the model, a narrative literature review was conducted. Secondly, we proposed an extended model in which the population (N) is divided into Susceptible (S), HIV-positive (I), Individual with AIDS (A) and individual under treatment (T). Each SDH had a different approach to embedding in the model. We performed a calibration and validation of the model. A total of 31 SDH were obtained in the review, divided into four groups: Individual Factors, Socioeconomic Factors, Social Participation, and Health Services. In the end, four determinants were selected for incorporation into the model: Education, Poverty, Use of Drugs and Alcohol abuse, and Condoms Use. the section "Numerical simulation" to simulate the influence of the poverty rate on the AIDS incidence and mortality rates. We used a Brazilian dataset of new AIDS cases and deaths, which is publicly available. We calibrated the model using a multiobjective genetic algorithm for the years 2003 to 2019. To forecast from 2020 to 2035, we assumed two lines of poverty rate representing (i) a scenario of increasing and (ii) a scenario of decreasing. To avoid overfitting, we fixed some parameters and estimated the remaining. The equations presented with the chosen SDH exemplify some approaches that we can adopt when thinking about modeling social effects on the occurrence of HIV. The model was able to capture the influence of the employment/poverty on the HIV/AIDS incidence and mortality rates, evidencing the importance of SDOH in the occurrence of diseases. The recognition of the importance of including the SDH in the modeling and studies on HIV/AIDS is evident, due to its complexity and multicausality. Models that do not take into account in their structure, will probably miss a great part of the real trends, especially in periods, as the current on, of economic crisis and strong socioeconomic changes.

Knowledge of viral load, PrEP, and HIV-related sexual risk among men who have sex with men in the Waterloo region

Gay, bisexual, and other men who have sex with men (GBMSM) remain most disproportionately affected by HIV in Canada. HIV-
related sexual risk behaviours have been linked to high HIV risk among GBMSM, but prior research has not focused on knowledge of viral load, and the risk it presents for HIV acquisition. The purpose of this study was to explore the relationship between HIV-related sexual risk behaviour and knowledge of viral load among GBMSM. A cross-sectional survey was conducted using a convenience sample of individuals age 16 and older who self-identified as LGBTQ and lived, worked, or resided in the Waterloo region, an urban-rural area in southwestern Ontario ( N = 526). Responses were analyzed from those identifying as GBMSM ( N = 269). Logistic regression models were created to explore sociodemographic, outness, social support, and HIV-related sexual risk variables associated with knowledge of viral load. Multivariable regression models were built to explore the same associations while controlling for confounders. HIV risk was not associated with knowledge of viral load in bivariate or multivariable analyses. Point estimates for low/negligible (odds ratio [OR] 1.10; 95% CI 0.46–2.51) and high risk (OR 1.88; 95% CI 0.68–5.20) suggest trends of higher knowledge with increased HIV risk. Men who engage in sexual risk behaviour may have increased sexual health literacy and awareness of biomedical interventions (e.g., pre-exposure prophylaxis, or PrEP) that reduce HIV risk. Policies are needed that promote acceptance of sexual orientation, improve awareness and access to PrEP, and ensure optimal delivery of HIV education to at-risk groups prior to engagement in higher risk activities.

Difference in the neurocognitive functions of WLWH and MLWH in an Italian cohort of people living with HIV

Based on the available literature, women living with HIV (WLWH) seem to show greater cognitive and emotional disadvantages than men living with HIV (MLWH). Our aim was to compare the cognitive performance of MLWH and WLWH in an Italian cohort of People Living With HIV (PLWH) and to analyse factors potentially contributing to sex differences in cognitive function. We ran a retrospective, cross-sectional analysis of a monocentric dataset of PLWH who were administered a standardized neuropsychological test battery (SNB) during routine clinical care. We enrolled 161 Italian PLWH who are on combined antiretroviral therapy (cART): 114 (70.8%) MLWH and 47 (29.2%) WLWH.

Global cognitive performance (composite z score) (GCP) was significantly higher in MLWH than WLWH [mean 0.19 (SD 0.85) vs − 0.13 (SD 0.96); p = 0.039]. Moreover, WLWH obtained significantly higher scores on the Zung Depression Scale than MLWH [mean 41.8 (SD 10.9) vs 36.7 (SD 9.2); p = 0.003]. However, there was no statistically significant direct effect between male sex and better GCP (p = 0.692) in the context of a mediation model. On the contrary, the associations between male sex and better GCP were mediated by higher level of education (a*b =  + 0.15, Bootstrap CI95 = 0.05 and 0.27) and a lower Zung depression score (a*b =  + 0.10, Bootstrap CI95 = 0.02 and 0.21).

In conclusion, the global cognitive performance of WLWH is lower than that of MLWH. However, other demographic and clinical factors besides sex might help explain differences in their neurocognitive functions and make it possible for us to monitor them and identify those patients most in need.

Associations with sub-optimal clinic attendance and reasons for missed appointments among heterosexual women and men living with HIV in London

Poor engagement in HIV care is associated with poorer health outcomes and increased mortality. Our survey examined experiential and circumstantial factors associated with clinic attendance among women (n = 250) and men (n = 106) in London with heterosexually-acquired HIV. While no associations were found for women, among men, sub-optimal attendance was associated with insecure immigration status (25.6% vs. 1.8%), unstable housing (32.6% vs. 10.2%) and reported effect of HIV on daily activities (58.7% vs. 40.0%). Among women and men on ART, it was associated with missing doses of ART (OR = 2.96, 95% CI:1.74-5.02), less belief in the necessity of ART (OR = 0.56, 95% CI:0.35-0.90) and more concern about ART (OR = 3.63, 95% CI:1.45-9.09). Not wanting to think about being HIV positive was the top reason for ever missing clinic appointments. It is important to tackle stigma and the underlying social determinants of health to improve HIV prevention, and the health and well-being of people living with HIV.

Patient and Physician Preferences for Regimen Attributes for the Treatment of HIV in the United States and Canada

A long-acting injectable (LAI) antiretroviral therapy (ART) regimen is now available as a treatment option for virologically suppressed adults with HIV-1. This study assessed preference for a LAI regimen using an online survey of virally suppressed people living with HIV (PLWH) and physicians treating HIV in the US and Canada. Preference was elicited in a discrete choice experiment (DCE) with three choice options (switch to a LAI regimen, switch to another daily oral ART regimen, or stay on their current daily oral ART regimen) and four treatment attributes. A total of 553 PLWH and 450 physicians completed the survey. From the DCE results, 59% of PLWH were predicted to prefer a LAI over an alternative oral ART or staying on their current oral treatment, and 55–66% of physicians were predicted to recommend LAI for PLWH, depending on the treatment challenge scenario presented. PLWH indicated LAI would remove daily reminders of HIV (75%) and reduce feelings of being stigmatized (68%). A majority of PLWH and physicians preferred a LAI over oral ART to overcome treatment challenges such as daily pill burden and adherence. These benefits of LAI ART along with preferences of PLWH and physicians can help to inform ART choice.

Factors associated with antiretroviral therapy adherence among people living with HIV in Haiti: a cross-sectional study

BACKGROUND

Socioeconomic, demographic and clinical factors can affect adherence to treatment among people living with HIV (PLH) and potentially have an impact on their prognosis and survival. The main objective of this study was to assess these factors as potential barriers to adherence among patients receiving care in central Haiti.

METHODS

A cross-sectional study was conducted among PLH receiving antiretroviral therapy (ART) at the TB/HIV clinic at St. Therese Hospital in Hinche, Haiti. A total of 426 potential participants were approached during their follow-up visits from June to August 2019, of whom 411 participated in the study. After giving informed consent, study participants completed a structured interview that included the Self-Report Item Scale (SRIS), a standard measure, to assess adherence. Socio-demographic, economic and clinical factors were assessed for their association with adherence.

RESULTS

The 411 participating patients represented 39% of the patient population at the TB/HIV clinic during the timeframe of the study. The mean age was 43.7 years (range: 19-80), 65.5% were female and 78.1% had only achieved a primary level of schooling. Nearly 78% had received ART for less than 10 years, 3.41% reported having poor adherence and 28% less than excellent adherence. Factors related to poor adherence in bivariate analysis were age less than 40 years (OR: 6.32, 95% CI 2.04-10.58, p < 0.01) and inability to meet basic needs (OR: 2.70, 95% CI 1.04-7.0, p = 0.03).

CONCLUSIONS

To improve medication adherence, the hospital should strengthen patient counselling of younger recipients of ART and provide financial assistance and other social service interventions. Studies should be implemented in other HIV management centers in Haiti and similar contexts to examine barriers to ART adherence with the goal of improving prognosis and survival in the long-term among PLH in resource-limited setting.

Determinants of losses in the latent tuberculosis infection cascade of care in Brazil

INTRODUCTION

Factors associated with losses in the latent tuberculosis infection (LTBI) cascade of care in contacts of patients with tuberculosis (TB) were investigated in a multicentre prospective cohort from highly endemic regions in Brazil.

METHODS

Close contacts of 1187 patients with culture-confirmed pulmonary TB were prospectively studied between 2015 and 2019, with follow-up of 6-24 months. Data on TB screening by clinical investigation, radiographic examination and interferon-gamma release assay (IGRA) were collected. Multivariable regressions were used to identify determinants of losses in the LTBI cascade.

RESULTS

Among 4145 TB contacts initially identified, 1901 were examined (54% loss). Among those examined, 933 were people living with HIV, ≤5 years old and/or had positive IGRA results, and therefore had a recommendation to start TB preventive treatment (TPT). Of those, 454 (23%) initiated treatment, and 247 (54% of those initiating; 26% of those in whom treatment was recommended) completed TPT. Multivariable regression analysis revealed that living with HIV, illiteracy and black/pardo (brown) race were independently associated with losses in the cascade.

CONCLUSION

There were losses at all LTBI cascade stages, but particularly at the initial screening and examination steps. Close contacts of low socioeconomic status and living with HIV were at heightened risk of not completing the LTBI cascade of care in Brazil.

Differences in HIV clinical outcomes amongst heterosexuals in the United Kingdom by ethnicity

OBJECTIVE

We investigated differences in clinical outcomes in heterosexual participants, by ethnicity in the UK Collaborative HIV Cohort Study from 2000 to 2017.

DESIGN

Cohort analysis.

METHODS

Logistic/proportional hazard regression assessed ethnic group differences in CD4+ cell count at presentation, engagement-in-care, combination antiretroviral therapy (cART) initiation, viral suppression and rebound.

RESULTS

Of 12 302 participants [median age: 37 (interquartile range: 31-44) years, 52.5% women, total follow-up: 85 846 person-years], 64.4% were black African, 19.1% white, 6.3% black Caribbean, 3.6% black other, 3.3% South Asian/other Asian and 3.4% other/mixed. CD4+ cell count at presentation amongst participants from non-white groups were lower than the white group. Participants were engaged-in-care for 79.6% of follow-up time; however, black and other/mixed groups were less likely to be engaged-in-care than the white group (adjusted odds ratios vs. white: black African: 0.70 (95% confidence interval (CI) 0.63-0.79], black Caribbean: 0.74 (0.63-0.88), other/mixed: 0.78 (0.62-0.98), black other: 0.81 (0.64-1.02)). Of 8867 who started cART, 79.1% achieved viral suppression, with no differences by ethnicity in cART initiation or viral suppression. Viral rebound (22.2%) was more common in the black other [1.95 (1.37-2.77)], black African [1.85 (1.52-2.24)], black Caribbean [1.73 (1.28-2.33)], South Asian/other Asian [1.35 (0.90-2.03)] and other/mixed [1.09 (0.69-1.71)] groups than in white participants.

CONCLUSION

Heterosexual people from black, Asian and minority ethnic (BAME) groups presented with lower CD4+ cell counts, spent less time engaged-in-care and were more likely to experience viral rebound than white people. Work to understand and address these differences is needed.

Improving public health service delivery response to address contraceptive needs of socio-economically disadvantaged HIV positive people in Maharashtra, India

Background

People living with HIV (PLHIV) receive free antiretroviral treatment (ART) in public health facilities of India. With improved life expectancy, unmet sexual and reproductive health needs of PLHIV have to be addressed through a converged programmatic response strategy. Evidence shows that socioeconomically disadvantaged women are most vulnerable to high reproductive morbidities, especially HIV positive women with an unmet need of contraception.

Methods

Programmatic convergence by linking ART and family planning services were strengthened at two public health facilities (district hospitals) generally accessed by disadvantaged socio-economic sections of the society. Barriers to linking services including stigma and discrimination were addressed through analysis of existing linkage situation, sensitization and training of healthcare providers and system-level interventions. This facilitated provider-initiated assessment of contraceptive needs of PLHIV, counseling about dual contraception using a couple approach, linkage to family planning centers and maintaining data about these indicators. Six hundred eligible PLHIV seeking care at ART centers were enrolled and followed up for a duration of 6 months. Acceptance of family planning services as a result of the intervention, use of dual contraception methods and their determinants were assessed.

Results

Eighty-seven percent HIV couples reached FP centers and 44.6% accepted dual methods at the end of the study period. Dual methods such as oral contraceptive pills (56.2%), IUCDs (19.4%), female sterilization (11.6%), injectable contraception (9.9%) and vasectomy (2.9%) in addition to condoms were the most commonly accepted methods. Condom use remained regular and consistently high throughout. The study witnessed seven unintended pregnancies, all among exclusive condom users. These women availed medical abortion services and accepted dual methods after counseling. Female index participants, concordant couples, counseling by doctors and women with CD4 count above 741 had higher odds of accepting dual contraception methods. Standard operating procedures (SOP) were developed in consultation with key stakeholders to address operational linkage of HIV and family programs.

Conclusion

The study saw significant improvement in acceptance of dual contraception by PLHIV couples as a result of the intervention. Implementation of SOPs with supportive supervision can ensure efficient linkage of programs and provide holistic sexual and reproductive healthcare for PLHIV in India.

Moving on from HAND: why we need new criteria for cognitive impairment in people with HIV and a proposed way forward

HIV-associated neurocognitive disorders (HAND) criteria are frequently used to describe cognitive impairment in people with HIV (PWH) across diverse populations globally. These criteria typically find 20-60% of PWH meet criteria for HAND, which does not tally with clinical observations in the modern era that cognitive disorders present relatively infrequently. Most with HAND have asymptomatic neurocognitive impairment (ANI), however the significance of low cognitive test performance without symptoms is uncertain. Methods underlying HAND criteria carry a false positive rate that can exceed 20%. Comorbidities, education and complex socioeconomic factors can influence cognitive test performance, further increasing the potential for misclassification. We propose a new framework to characterise cognitive impairment in PWH which requires a clinical history and acknowledges the multifactorial nature of low cognitive test performance. This framework is intended to be applicable across diverse populations globally, be more aligned with clinical observations and more closely represent HIV brain pathology.

Characterization of people living with HIV in a Montreal-based tertiary care center with COVID-19 during the first wave of the pandemic

People living with HIV (PLWH) often have worse health outcomes compared to HIV-uninfected individuals. We characterized PLWH followed at a tertiary care clinic in Montreal who acquired COVID-19 and described their outcomes during the first wave of the pandemic. A retrospective chart review was performed for PLWH followed at the Chronic Viral Illness Service with a positive COVID-19 nasopharyngeal PCR or symptoms suggestive of COVID-19 between 1 March and 15 June 2020. Data on demographics, socioeconomic status, co-morbidities and severity of COVID-19 and outcomes were extracted. Of 1702 individuals, 32 (1.9%) had a positive COVID-19 test (n = 24) or symptoms suspicious for COVID-19 (n = 3). Median age was 52 years [IQR 40, 62]. Nearly all (97%) earned $34,999 Canadian dollars or less. Eleven (34%) individuals worked in long-term care (LTC) homes while 5 (6%) lived in LTC homes. Median CD4 count was 566 cells/mm³ [347, 726] and six had detectable plasma HIV viral loads. Median duration of HIV was 17 years [7, 22] and 30 individuals had been prescribed antiretroviral therapy. Five persons were asymptomatic. Of symptomatic persons, 21 (12%), 1 (4%) and 3 (12%) individuals had mild, moderate and severe disease, respectively. Three individuals died with COVID-19. In one case, the cause of death was due to COVID-19, whereas in the other two cases, the individuals died with positive COVID-19 test results but the immediate cause of death is unclear. PLWH who tested positive for COVID-19 had low socioeconomic status and had employment or living conditions that put them at high risk. PLWH may be disproportionately impacted by the social determinants of health which predispose them to COVID-19.

Sociodemographic factors affecting viral load suppression among people living with HIV in South Carolina

Adherence to antiretroviral therapy (ART) enables people living with HIV (PLWH) to reach and maintain viral suppression. As viral suppression significantly reduces risk for secondary transmission, this study aimed to examine sociodemographic factors associated with viral suppression among PLWH in South Carolina (SC). We analyzed cross-sectional data collected from 342 PLWH receiving HIV care from a large clinic in SC and provided complete information on most recent viral load, ART adherence, and sociodemographic factors. Bivariate analysis examined associations between key variables, and logistic regression was used to calculate the odds of viral suppression among select sociodemographic groups and adherence levels. Results indicated that approximately 82% of participants reported achieving viral suppression. PLWH who were older, male, and employed full-time had higher odds of being virally suppressed compared to those who were younger, female, and unemployed. PLWH with medium (adjusted Odds Ratio [aOR]: 3.79; 95% CI: 1.15-12.48) and high (aOR: 3.51; 95% CI: 1.21-10.24) levels of adherence were more likely to report viral suppression than those with low adherence. Targeted interventions are warranted for groups at-risk of low ART adherence, and healthcare providers should also be aware of contextual factors that serve as barriers to adherence for PLWH.

All-cause hospitalization according to demographic group in people living with HIV in the current antiretroviral therapy era

OBJECTIVE

We investigated differences in all-cause hospitalization between key demographic groups among people with HIV in the UK in the current antiretroviral therapy (ART) era.

DESIGN/METHODS

We used data from the Royal Free HIV Cohort study between 2007 and 2018. Individuals were classified into five groups: MSM, Black African men who have sex with women (MSW), MSW of other ethnicity, Black African women and women of other ethnicity. We studied hospitalizations during the first year after HIV diagnosis (Analysis-A) separately from those more than one year after diagnosis (Analysis-B). In Analysis-A, time to first hospitalization was assessed using Cox regression adjusted for age and diagnosis date. In Analysis-B, subsequent hospitalization rate was assessed using Poisson regression, accounting for repeated hospitalization within individuals, adjusted for age, calendar year, time since diagnosis.

RESULTS

The hospitalization rate was 30.7/100 person-years in the first year after diagnosis and 2.7/100 person-years subsequently; 52% and 13% hospitalizations, respectively, were AIDS-related. Compared with MSM, MSW and women were at much higher risk of hospitalization during the first year [aHR (95% confidence interval, 95% CI): 2.7 (1.7-4.3), 3.0 (2.0-4.4), 2.0 (1.3-2.9), 3.0 (2.0-4.5) for Black African MSW; other ethnicity MSW; Black African women; other ethnicity women respectively, Analysis-A] and remained at increased risk subsequently [corresponding aIRR (95% CI): 1.7 (1.2-2.4), 2.1 (1.5-2.8), 1.5 (1.1-1.9), 1.7 (1.2-2.3), Analysis-B].

CONCLUSION

In this setting with universal healthcare, substantial variation exists in hospitalization risk across demographic groups, both in early and subsequent periods after HIV diagnosis, highlighting the need for targeted interventions.

Prospective association of social circumstance, socioeconomic, lifestyle and mental health factors with subsequent hospitalisation over 6-7 year follow up in people living with HIV

BACKGROUND

Predictors of hospitalisation in people with HIV (PLHIV) in the contemporary treatment era are not well understood.

METHODS

This ASTRA sub-study used clinic data linkage and record review to determine occurrence of hospitalisations among 798 PLHIV from baseline questionnaire (February to December 2011) until 1 June 2018. Associations of baseline social circumstance, socioeconomic, lifestyle, mental health, demographic and clinical factors with repeated all-cause hospitalisation from longitudinal data were investigated using Prentice-Williams-Peterson models. Associations were also assessed in 461 individuals on antiretroviral therapy (ART) with viral load ≤50 copies/ml and CD4 count ≥500 cells/ µl.

FINDINGS

Rate of hospitalisation was 5.8/100 person-years (95% CI: 5.1-6.5). Adjusted for age, demographic group and time with diagnosed HIV, the following social circumstance, socioeconomic, lifestyle and mental health factors predicted hospitalisation: no stable partner (adjusted hazard ratio (aHR)=1.59; 95% CI=1.16-2.20 vs living with partner); having children (aHR=1.50; 1.08-2.10); non-employment (aHR=1.56; 1.07-2.27 for unemployment; aHR=2.39; 1.70-3.37 for sick/disabled vs employed); rented housing (aHR=1.72; 1.26-2.37 vs homeowner); not enough money for basic needs (aHR=1.82; 1.19-2.78 vs enough); current smoking (aHR=1.39; 1.02-1.91 vs never); recent injection-drug use (aHR=2.11; 1.30-3.43); anxiety symptoms (aHRs=1.39; 1.01-1.91, 2.06; 1.43-2.95 for mild and moderate vs none/minimal); depressive symptoms (aHRs=1.67; 1.17-2.38, 1.91; 1.30-2.78 for moderate and severe vs none/minimal); treated/untreated depression (aHRs=1.65; 1.03-2.64 for treated depression only, 1.87; 1.39-2.52 for depressive symptoms only; 1.53; 1.05-2.24; for treated depression and depressive symptoms, versus neither). Associations were broadly similar in those with controlled HIV and high CD4.

INTERPRETATION

Social circumstance, socioeconomic disadvantage, adverse lifestyle factors and poorer mental health are strong predictors of hospitalisation in PLHIV, highlighting the need for targeted interventions and care.

Treatment Satisfaction and Its Associated Factors of Dolutegravir Based Regimen in a Resource Limited Setting

INTRODUCTION

Treatment satisfaction is patient's evaluation of the process of taking the medication and its use. Currently dolutegravir based regimen is first-line agent for treatment of human immunodeficiency virus. But evidence is scarce regarding treatment satisfaction. Thus, the aim of the current study was to assess treatment satisfaction and associated factors of dolutegravir based regimen among adult human immunodeficiency virus patients attending at Debre Markos referral 2020.

METHODS

Institutional-based cross-sectional study was conducted. A systematic random sampling technique was used to collect data from June 25 to August 25, 2020 at Debre Markos referral hospital. It was entered into Epi Info and exported to SPSS version 23 for analysis. Bivariable and multivariable logistic regression was used to identify factors. Variables with p<0.05 were considered as statistically significant.

RESULTS

From a total of 359, 349 participants (97.2%) responded to the study. In this study, 70.5% of participants reported higher treatment satisfaction. Monthly average income of ≥3500 birr (AOR: 2.88; 95% CI: 1.26, 6.58), 1600-2500 birr (AOR: 2.47; 95% CI: 1.11, 5.48), 800-1600 birr (AOR: 3.11; 95% CI: 1.31, 7.37), positive belief about medications (AOR: 3.05; 1.76, 5.28), having a discussion with health care providers (AOR: 3.05, 95% CI: 1.58, 5.88), patients without concurrent medication (AOR: 7.72, 95% CI: 3.29, 18.07), and being male (AOR: 2.10, 95% CI: 1.14, 3.87) were associated with treatment satisfaction.

CONCLUSION

Overall, dolutegravir based regimen showed high treatment satisfaction. Monthly income, positive beliefs about medications, discussing about treatment options, sex and concurrent medications were associated with treatment satisfaction. Thus, it is crucial to improve treatment satisfaction by promoting positive belief towards medication and also by engaging patients in treatment decisions.

Understanding the needs and use of sexual and reproductive health services among Thai women: a descriptive cross-sectional study in Sweden

Background Immigrants are at increased risk of HIV infection in Europe and at risk of delayed diagnosis. In Sweden, Thailand belongs to one of the three most common countries of origin among immigrants diagnosed with HIV. This study investigated the need and use of sexual and reproductive health (SRH) services among Thai women residing in Sweden. Use of contraceptives and HIV testing in Thailand was also investigated to understand if this influences utilisation of SRH services in Sweden.

METHODS

A cross-sectional study using postal questionnaire to all Thai-born women (age 23-60) in Stockholm, residing in Sweden since 2014. The response rate was 52.3% (n= 266). Bivariate and multivariate logistic regression analyses were used.

RESULTS

The majority reported a significant need for information related to SRH services. Most of the women using contraception (70%) bought their contraceptives in Thailand. In total, 60% of the women had been HIV-tested at some point in their lives; the majority were tested in Thailand. Women who had been HIV-tested in Thailand were more likely to also have been tested in Sweden. Significant differences in contraception use, participation in contraceptive counselling and having had an HIV test were found between groups of younger and older women.

CONCLUSIONS

Our findings imply that age is an important factor to understand women's need and use of SRH services in Sweden versus Thailand. Furthermore, women's lack of knowledge and reported need for SRH information needs to be considered when making policies and strategies to increase access to SRH services.

Socio-economic condition and lack of virological suppression among adults and adolescents receiving antiretroviral therapy in Ethiopia

Introduction

The potential impact of socio-economic condition on virological suppression during antiretroviral treatment (ART) in sub-Saharan Africa is largely unknown. In this case-control study, we compared socio-economic factors among Ethiopian ART recipients with lack of virological suppression to those with undetectable viral load (VL).

Methods

Cases (VL>1000 copies/ml) and controls (VL<150 copies/ml) aged ≥15years, with ART for >6 months and with available VL results within the last 3 months, were identified from registries at public ART clinics in Central Ethiopia. Questionnaire-based interviews on socio-economic characteristics, health condition and transmission risk behavior were conducted. Univariate variables associated with VL>1000 copies/ml (p<0.25) were added to a multivariable logistic regression model.

Results

Among 307 participants (155 cases, 152 controls), 61.2% were female, and the median age was 38 years (IQR 32–46). Median HIV-RNA load among cases was 6,904 copies/ml (IQR 2,843–26,789). Compared to controls, cases were younger (median 36 vs. 39 years; p = 0.004), more likely to be male (46.5% vs. 30.9%; p = 0.005) and had lower pre-ART CD4 cell counts (170 vs. 220 cells/μl; p = 0.009). In multivariable analysis of urban residents (94.8%), VL>1000 copies/ml was associated with lower relative wealth (adjusted odds ratio [aOR] 2.98; 95% CI 1.49–5.94; p = 0.016), geographic work mobility (aOR 6.27, 95% CI 1.82–21.6; p = 0.016), younger age (aOR 0.94 [year], 95% CI 0.91–0.98; p = 0.011), longer duration of ART (aOR 1.19 [year], 95% CI 1.07–1.33; p = 0.020), and suboptimal (aOR 3.83, 95% CI 1.33–10.2; p = 0.048) or poor self-perceived wellbeing (aOR 9.75, 95% CI 2.85–33.4; p = 0.012), after correction for multiple comparisons. High-risk sexual behavior and substance use was not associated with lack of virological suppression.

Conclusion

Geographic work mobility and lower relative wealth were associated with lack of virological suppression among Ethiopian ART recipients in this predominantly urban population. These characteristics indicate increased risk of treatment failure and the need for targeted interventions for persons with these risk factors.

Elevated risk of viral rebound on ART in migrants living in France: role of socioeconomic factors

BACKGROUND

In Western countries, viral rebound on antiretroviral therapy (ART) appears to occur more frequently in migrants. We aimed to assess the respective roles of socioeconomic factors and migration on viral rebound in people living with HIV (PLHIV) in France.

METHODS

We included PLHIV in France, enrolled from 2004 to 2008 in the French ANRS-COPANA cohort, who started a first ART and achieved undetectability (<50 copies/ml) within 1 year. Determinants of viral rebound were assessed using Cox models including geographical origin, HIV transmission group, and clinicobiological and sociodemographic data.

RESULTS

Of 499 included individuals, 288 were born in France, 158 in sub-Saharan Africa (SSA) and 53 in another country. Kaplan-Meier probabilities of viral rebound-free survival were similar for men having sex with men (MSM) and heterosexuals born in France, and lower in migrants from SSA or other countries (P<0.001). The crude hazard ratio (HR) of viral rebound was 2.49 (95% CI, 1.59, 3.90) in migrants from SSA and 1.78 (0.94, 3.88) in migrants from other countries compared with MSM born in France. Educational level, financial difficulties and HIV status disclosure had the biggest impact on the difference between the crude and adjusted HRs for viral rebound in migrants. In multivariable analysis, viral rebound was no longer associated with geographical origin, but with protease inhibitor-containing ART, a VACS index ≥35 as a potential indicator of frailty, poor financial status (difficulties or debts) and non-disclosure to friend(s).

CONCLUSIONS

Socioeconomic factors affect outcomes on ART, even in the context of free access to HIV care and treatment. Patient-centred strategies should be encouraged with the intervention of social workers to address basic needs and promote social support for more socially vulnerable individuals.

Trends of Cause of Death among Human Immunodeficiency Virus Patients and the Impact of Low CD4 Counts on Diagnosis to Death: a Retrospective Cohort Study

BACKGROUND

Monitoring the full spectrum of causes of death among human immunodeficiency virus (HIV) patients has become increasingly important as survival improves because of highly active antiretroviral therapy. However, there are no recently published data regarding the changes in the causes of death among HIV patients based on year of HIV diagnosis, and the impact of low CD4 count at the time of HIV diagnosis on the clinical outcome is still unclear in Korea.

METHODS

A retrospective cohort study was conducted with 801 patients with HIV infection who were followed up at a tertiary university hospital and diagnosed with HIV between July 1984 and October 2019. The causes of death were analyzed by descriptive analysis based on CD4 count and the year of HIV diagnosis. Kaplan-Meier and log rank tests were performed to compare the prognosis between the CD4 < 200 cells/mm³ and CD4 ≥ 200 cells/mm³ groups.

RESULTS

Among 801 patients, 67 patients were eligible for the death cause analysis. Infection-related death accounted for 44 patients (65.7%) and non-infection related death accounted for 23 patients (32.4%). Pneumocystis pneumonia (29.9%) was the single most common cause of death in both past and present cases, and tuberculosis (19.4%) was the second leading cause of death from infections, but the frequency has declined in recent years. Causes of infection-related death have decreased, whereas non-infection related causes of death have increased remarkably. Malignancy-related death was the most common cause of non-infection related death. Acquired immunodeficiency syndrome (AIDS) non-related malignancy accounted for 11.9%, whereas AIDS-related malignancy accounted for 6.0% of the total death among HIV patients. No significant statistical differences were found in mortality rate (P = 0.228), causes of death (P = 0.771), or survival analysis (P = 0.089) between the CD4 < 200 cells/mm³ and CD4 ≥ 200 cells/mm³ groups.

CONCLUSION

Being diagnosed with CD4 < 200 cells/mm³ at the time of HIV diagnosis was not an indicator of greater risk of death compared with the CD4 ≥ 200 cells/mm³ group. Malignant tumors have become an important cause of death in recent years, and an increasing tendency of AIDS-non-related malignancy causes has been observed.

Use of HIV pre-exposure prophylaxis among men who have sex with men in England: data from the AURAH2 prospective study

BACKGROUND

Since October, 2017 (and until October, 2020), pre-exposure prophylaxis (PrEP) has only been available in England, UK, through the PrEP Impact Trial, by purchasing it from some genitourinary medicine clinics, or via online sources. Here we report changes from 2013 to 2018 in PrEP and postexposure prophylaxis (PEP) awareness and use among HIV-negative gay, bisexual, and other men who have sex with men (MSM) and assess predictors of PrEP initiation.

METHODS

In the prospective cohort study Attitudes to, and Understanding of Risk of Acquisition of HIV 2 (AURAH2), MSM were recruited from three sexual health clinics in England: two in London and one in Brighton, UK. Men were eligible if they were aged 18 years or older and HIV-negative or of unknown HIV status. Participants self-completed a baseline paper questionnaire at one of the three clinics between July 30, 2013, and April 30, 2016, and were subsequently able to complete 4-monthly and annual online questionnaires, which were available between March 1, 2015, and March 31, 2018, and collected information on sociodemographics, health and wellbeing, HIV status, and sexual behaviours. PrEP and PEP use in the previous 12 months was obtained at baseline and in annual questionnaires. We assessed trends over calendar time in 3-month periods from first enrolment to the end of the study period (July-December, 2013, was counted as one period) in use of PrEP and PEP using generalised estimating equation logistic models. We used age-adjusted Poisson models to assess factors associated with PrEP initiation among participants who reported never having used PrEP at baseline.

FINDINGS

1162 men completed a baseline questionnaire, among whom the mean age was 34 years (SD 10·4), and of those with available data, 942 (82%) of 1150 were white, 1076 (94%) of 1150 were gay, and 857 (74%) of 1159 were university educated. 622 (54%) of 1162 men completed at least one follow-up online questionnaire, of whom 483 (78%) completed at least one annual questionnaire. Overall, PrEP use in the past year increased from 0% (none of 28 respondents) in July to December, 2013, to 43% (23 of 53) in January to March, 2018. The corresponding increase in PrEP use among men who reported condomless sex with two or more partners was from 0% (none of 13 respondents) to 78% (21 of 27). PEP use peaked in April to June, 2016, at 28% (41 of 147 respondents), but decreased thereafter to 8% (four of 53) in January to March, 2018. Among 460 men who had never used PrEP at baseline, predictors of initiating PrEP included age 40-44 years (incidence rate ratio [IRR] 4·25, 95% CI 1·14-15·79) and 45 years and older (3·59, 1·08-11·97) versus younger than 25 years; and after adjustment for age, recent HIV test (5·17, 1·89-14·08), condomless sex (5·01, 2·16-11·63), condomless sex with two or more partners (5·43, 2·99-9·86), group sex (1·69, 1·01-2·84), and non-injection chemsex-related drugs use (2·86, 1·67-4·91) in the past 3 months, PEP use (4·69, 2·83-7·79) in the past 12 months, and calendar year (Jan 1, 2017, to March 31, 2018 vs July 30, 2013, to Dec 31, 2015: 21·19, 9·48-47·35). Non-employment (0·35, 0·14-0·91) and unstable or no housing (vs homeowner 0·13, 0·02-0·95) were associated with reduced rates of PrEP initiation after adjustment for age. About half of PrEP was obtained via the internet, even after the PrEP Impact trial had started (11 [48%] of 23 respondents in January to March, 2018).

INTERPRETATION

PrEP awareness and use increased substantially from 2013 to 2018 among a cohort of MSM in England. Improving access to PrEP by routine commissioning by National Health Service England could increase PrEP use among all eligible MSM, but should include public health strategies to target socioeconomic and demographic disparities in knowledge and use of PrEP.

Treatment outcome of the implementation of HIV test and treat policy at The AIDs Support Organization (TASO) Tororo clinic, Eastern Uganda: A retrospective cohort study

BACKGROUND

Uganda has been making progress towards universal HIV test and treat since 2013 and the 2016 test and treat policy was expanded from the 2013 guidelines. The expanded policy was rolled out in 2017 across the country. The treatment outcomes of this new policy have not yet been assessed at program level. The objective of this study was to determine the treatment outcome of the HIV test and treat policy in TASO Tororo Clinic, Eastern Uganda.

METHODOLOGY

This was a retrospective cohort study using secondary data. The study involved 580 clients who were newly diagnosed HIV positive in TASO Tororo clinic between June 2017 and May 2018, who were then followed up for ART initiation, retention in care, viral load monitoring and viral load suppression. The data was analyzed using Stat 14.0 version statistical software application.

RESULTS

Of the 580 clients, 93.1%(540) were adults aged ≥20 years. The uptake of test and treat was at 92.4%(536) and 12 months retention was at 78.7% (422). The factors associated with retention in care were a) being counselled before ART initiation, AOR 2.41 (95%CI, 1.56-3.71), b) having a treatment supporter, AOR 1.57 (95%CI, 1.02-2.43) and having an opportunistic infection, AOR 2.99 (95%CI:1.21-7.41). The viral load coverage was 52.4% (221) and viral load suppression rate was 89.1% (197) of clients monitored. Age <20 years was the only identified factor associated with vial load non suppression, AOR 7.35 (95% CI = 2.23-24.24).

CONCLUSION

This study found high uptake of ART under test and treat policy, with very low viral load coverage, and a high viral load suppression rate among those monitored. The study therefore highlights a need to differentiate viral load testing based on the population needs and ensure each client testing positive receives pre-ART initiation counselling so as to improve retention in care.

mHealth Interventions to Promote Anti-Retroviral Adherence in HIV: Narrative Review

Background

Antiretrovirals (ARVs) are key in the management of HIV. Although no cure exists, ARVs help patients live healthy lives and prevent transmission to others. Adherence to complex regimens is paramount to outcomes and in avoiding the emergence of drug-resistant viruses. The goal of therapy is to reach an undetectable viral load. However, adherence is a common problem, stemming from issues such as mental health, chaotic home situations, and busy work schedules. Mobile health (mHealth) represents a new approach in improving medication adherence, and multiple studies have been performed in this area.

Objective

This study aims to review the current implementation of mHealth in the management of HIV among different groups of patients.

Methods

We used PubMed, Academic Search Elite, and 1 journal database with various search terms to review the current implementation of mHealth in HIV care.

Results

Titles and abstracts were screened, and 61 papers were identified and fully reviewed. The literature was divided into lower- and higher-income nations, as defined by the United Nations. A total of 20 studies with quantitative results were identified, with 10 being text- and SMS-based interventions (the majority of these being in lower-income countries) and 8 being smartphone-based apps (primarily in higher-income countries). The majority of these studies determined whether there was an effect on adherence or biochemical parameters (viral load and CD4 count). Various qualitative studies have also been conducted, and many have focused on determining the specific design of interventions that were successful (frequency of messaging, types of messages, etc) as well as priorities for patients with regard to mHealth interventions.

Conclusions

There seems to be a role of mHealth in the management of HIV in lower-income nations; however, the optimal design of an intervention needs to be delineated. In higher-income countries, where the 2 significant risk factors were injection drugs and men who have sex with men, the benefit was less clear, and more research is needed.

Is the technical quality of root fillings associated with socioeconomic status? A cross-sectional study among Finnish adults

We investigated differences in the technical quality of root fillings according to socioeconomic status. In the Finnish Health 2000 Survey, which comprised a sample of 8,028 adults aged over 29 yr, 6,115 underwent panoramic radiography. A total of 7,986 endodontically treated teeth were detected among 3,095 participants. The criterion for a technically inadequate root filling was a distance from the root filling to the root apex of over 3 mm or a filling extruding beyond the apex. Educational level, employment status, and income were the measures of socioeconomic status. Differences in the frequency of inadequate root fillings according to socioeconomic status were investigated using a multilevel logistic mixed-effects model taking into account age, gender, number of teeth, and type of root filled tooth. Almost half (46%) of the root fillings were inadequate. Among the over 64-yr-olds, higher education and higher income were associated with a higher probability of having an inadequate root filling. Among the under 65-yr-olds, socioeconomic status was not associated with root filling quality. Contrary to expectation, lower socioeconomic status was not associated with poorer endodontic treatment quality; however, higher income and higher education was associated with higher odds for inadequate root fillings among the over 64-yr-olds.

Challenges of reaching 90-90-90 in the Southern United States

PURPOSE OF REVIEW

More than half of new HIV diagnoses occur in the Southern United States where the epidemic disproportionately affects persons of color. Although other areas of the country are seeing dramatic declines in the number of new cases, the progress in the South lags behind. This review will examine the reasons for that disparity. Many are unique to the South.

RECENT FINDINGS

Despite advances in antiretroviral therapy for HIV, many in the South are not benefiting from these medications, at either a personal or public health level. The reasons are complex and include lack of access to healthcare, lower levels of funding than other areas of the country, stigma, structural racism, increased barriers due to social determinants of health, coexisting mental health disorders, substance use disorders and sexually transmitted diseases and insufficient workforce capacity to meet the needs of those living with HIV.

SUMMARY

These findings should underline the need for investment in the South for a holistic healthcare approach to persons living with HIV including supporting basic needs such as access to food, transportation and housing. Prioritization among politicians for policy and systems changes and approaches to decrease stigma and enhance education about HIV will be key.

Socioeconomic and Demographic Statuses as Determinants of Adherence to Antiretroviral Treatment in HIV Infected Patients: A Systematic Review of the Literature

BACKGROUND

Socioeconomic and demographic statuses are associated with adherence to the treatment of patients with several chronic diseases. However, there is a controversy regarding their impact on adherence among HIV/AIDS patients. Thus, we performed a systematic review of the evidence regarding the association of socioeconomic and demographic statuses with adherence to antiretroviral therapy (ART) among HIV/AIDS patients.

METHODS

The PubMed database was used to search and identify studies concerning about socioeconomic and demographic statuses and HIV/AIDS patients. Data were collected on the association between adherence to ART and varies determinants factors of socioeconomic (income, education, and employment/occupation) and socio-demographic (sex and age).

FINDINGS

From 393 potentially-relevant articles initially identified, 35 original studies were reviewed in detail, which contained data that were helpful in evaluating the association between socioeconomic/ demographic statuses and adherence to ART among HIV patients. Two original research study has specifically focused on the possible association between socioeconomic status and adherence to ART. Income, level of education, and employment/occupational status were significantly and positively associated with the level of adherence in 7 studies (36.8%), 7 studies (28.0%), and 4 studies (23.5%) respectively out of 19, 25, and 17 studies reviewed. Sex (being male), and age (per year increasing) were significantly and positively associated with the level of adherence in 5 studies (14.3%), and 9 studies (25.7%) respectively out of 35 studies reviewed. However, the determinant of socioeconomic and demographic statuses was not found to be significantly associated with adherence in studies related to income 9(47.4%), education 17(68.0%), employment/ occupational 10(58.8%), sex 27(77.1%), and age 25(71.4%).

CONCLUSION

The majority of the reviewed studies reported that there is no association between socio- demographic and economic variables and adherence to therapy. Whereas, some studies show that age of HIV patients (per year increasing) and sex (being male) were positively associated with adherence to ART. Among socio-economic factors, the available evidence does not provide conclusive support for the existence of a clear association with adherence to ART among HIV patients. There seems to be a positive trend between socioeconomic factors and adherence to ART in some of the reviewed studies.

Virological outcomes of boosted protease inhibitor-based first-line ART in subjects harbouring thymidine analogue-associated mutations as the sole form of transmitted drug resistance

Objectives

In subjects with transmitted thymidine analogue mutations (TAMs), boosted PIs (PI/b) are often chosen to overcome possible resistance to the NRTI backbone. However, data to guide treatment selection are limited. Our aim was to obtain firmer guidance for clinical practice using real-world cohort data.

Methods

We analysed 1710 subjects who started a PI/b in combination with tenofovir or abacavir plus emtricitabine or lamivudine, and compared their virological outcomes with those of 4889 patients who started an NNRTI (predominantly efavirenz), according to the presence of ≥1 TAM as the sole form of transmitted drug resistance.

Results

Participants with ≥1 TAM comprised predominantly MSM (213 of 269, 79.2%), subjects of white ethnicity (206 of 269, 76.6%) and HIV-1 subtype B infections (234 of 269, 87.0%). Most (203 of 269, 75.5%) had singleton TAMs, commonly a revertant of T215Y or T215F (112 of 269, 41.6%). Over a median of 2.5 years of follow-up, 834 of 6599 (12.6%) subjects experienced viraemia (HIV-1 RNA >50 copies/mL). The adjusted HR for viraemia was 2.17 with PI/b versus NNRTI-based therapy (95% CI 1.88–2.51; P < 0.001). Other independent predictors of viraemia included injecting drug use, black ethnicity, higher viral load and lower CD4 cell count at baseline, and receiving abacavir instead of tenofovir. Resistance showed no overall impact (adjusted HR 0.77 with ≥1 TAM versus no resistance; 95% CI 0.54–1.10; P = 0.15).

Conclusions

In this cohort, patients harbouring ≥1 TAM as the sole form of transmitted drug resistance gained no apparent virological advantage from starting first-line ART with a PI/b.

Incidences and factors associated with viral suppression or rebound among HIV patients on combination antiretroviral therapy from three counties in Kenya

BACKGROUND

Limited data are available on the incidence and factors associated with viral rebound following viral suppression among HIV-infected individuals taking antiretroviral therapy (ART) in Kenya. Furthermore, the durability of viral suppression among HIV individuals taking ART is unknown. Information on incidence rates and factors associated with HIV viral load rebound and the durability of viral suppression (undetectable HIV copies in plasma) among HIV-infected individuals taking ART, will help improve the long-term management of HIV-infected individuals and explore approaches to long-term HIV remission or complete cure.

OBJECTIVES

The objectives of this study were to investigate the incidence rates of viral rebound following viral suppression, factors associated with viral rebound, and the durability of viral suppression among HIV-infected individuals on ART from Kilifi, Meru, and Nakuru counties in Kenya.

METHODS

This was a retrospective study involving 600 HIV-infected individuals taking combination ART (cART) and enrolled in comprehensive care centers (CCCs) at Malindi Sub-county Hospital, Nakuru Level 5 Hospital, and Meru Level 5 Hospital in Kenya. The medical files were inspected and medical history records abstracted for the selected participants. Participant laboratory data including HIV viral loads, types and history of ART, and treatment history of any opportunistic infections were abstracted using an abstraction checklist. Participants were grouped into those who achieved HIV viral suppression, with viral loads lower than the detection limit (LDL) (viral suppression), and those who experienced one or more detectable viral load measurements >40 copies/ml following the initial LDL (viral rebound). Durable viral suppression was defined as all viral load values at LDL over the 2-year period (2017-2019). Univariate and multivariate Poisson regression analyses were performed to assess the rates of viral rebound, as well as to investigate factors associated with it.

RESULTS

Out of 549 HIV-positive patients, 324/549 (59%) achieved HIV viral suppression (Meru 159/194 (82%), Nakuru 21/178 (12%), and Malindi 144/177 (81%)). The overall viral rebound rate was 41%, with site-specific viral rebound of 88.2%, 18.6%, and 18.0% in Nakuru, Malindi, and Meru, respectively. There was an overall rate of first viral rebound of 3.9 (95% confidence interval (CI) 6.9-14.4), 0.7 (95% CI 0.5-1.0), and 0.89 (95% CI 0.64-1.24) per 100 person-months in Nakuru, Malindi, and Meru, respectively. Good ART adherence (p = 0.0002), widow status (p = 0.0062), and World Health Organization (WHO) stage I (p = 0.0002) were associated with viral suppression, while poor ART adherence (p < 0.0001), WHO stage II (p = 0.0024), and duration on ART of 36 months (p = 0.0350) were associated with viral rebound.

CONCLUSIONS

The rate of viral suppression in patients on cART in the CCCs fell short of the WHO target. However, the study provides proof of evidence of undetectable viral load levels for more than 2 years, a sign that the United Nation's 2030 objective of controlling the risk of HIV transmission could be achieved.

Modeling Viral Suppression, Viral Rebound and State-Specific Duration of HIV Patients with CD4 Count Adjustment: Parametric Multistate Frailty Model Approach

INTRODUCTION

Combination antiretroviral therapy has become the standard care of human immunodeficiency virus (HIV)-infected patients and has further led to a dramatically decreased progression probability to acquired immune deficiency syndrome (AIDS) for patients under such a therapy. However, responses of the patients to this therapy have recorded heterogeneous complexity and high dynamism. In this paper, we simultaneously model long-term viral suppression, viral rebound, and state-specific duration of HIV-infected patients.

METHODS

Full-parametric and semi-parametric Markov multistate models were applied to assess the effects of covariates namely TB co-infection, educational status, marital status, age, quality of life (QoL) scores, white and red blood cell parameters, and liver enzyme abnormality on long-term viral suppression, viral rebound and state-specific duration for HIV-infected individuals before and after treatment. Furthermore, two models, one including and another excluding the effect of the frailty, were presented and compared in this study.

RESULTS

Results from the diagnostic plots, Akaike information criterion (AIC) and likelihood ratio test showed that the Weibull multistate frailty model fitted significantly better than the exponential and semi-parametric multistate models. Viral rebound was found to be significantly associated with many sex partners, higher eosinophils count, younger age, lower educational level, higher monocyte counts, having abnormal neutrophils count, and higher liver enzyme abnormality. Furthermore, viral suppression was also found to be significantly associated with higher QoL scores, and having a stable sex partner. The analysis result also showed that patients with a stable sex partner, higher educational levels, higher QoL scores, lower eosinophils count, lower monocyte counts, and higher RBC indices were more likely to spend more time in undetectable viral load state.

CONCLUSIONS

To achieve and maintain the UNAIDS 90% suppression targets, additional interventions are required to optimize antiretroviral therapy outcomes, specifically targeting those with poor clinical characteristics, lower education, younger age, and those with many sex partners. From a methodological perspective, the parametric multistate approach with frailty is a flexible approach for modeling time-varying variables, allowing for dealing with heterogeneity between the sequence of transitions, as well as allowing for a reasonable degree of flexibility with a few additional parameters, which then aids in gaining a better insight into how factors change over time.

The same lesson over and over: drugs alone will not get us to 90--90--90

: Addressing social determinants of health (SDH) has far greater potential to improve the real-world effectiveness of HIV treatment than expensive, incremental changes in antiretroviral therapy. The ADVANCE study demonstrates that SDH is more impactful than medication regimen on health outcomes. Younger patients and unemployed patients experience heightened precarity, which can have pervasive effects on adherence and suppression. Enhanced adherence counselling can help socioeconomically precarious patients maintain suppression, but in order to improve treatment effectiveness and population health, we should move beyond the short-term solution of helping patients 'cope' with insecurity toward tackling the underlying factors that lead to precarity. Data on intention-to-treat populations are critical to this effort, yet medical researchers and publications continue to obscure the influence of SDH by focusing on per-protocol populations.

Trends and Adaptive Optimal Set Points of CD4+ Count Clinical Covariates at Each Phase of the HIV Disease Progression

In response to invasion by the human immunodeficiency virus (HIV), the self-regulatory immune system attempts to restore the CD4+ count fluctuations. Consequently, many clinical covariates are bound to adapt too, but little is known about their corresponding new optimal set points. It has been reported that there exist few strongest clinical covariates of the CD4+ count. The objective of this study is to harness them for a streamlined application of multidimensional viewing lens (statistical models) to zoom into the behavioural patterns of the adaptive optimal set points. We further postulated that the optimal set points of some of the strongest covariates are possibly controlled by dietary conditions or otherwise to enhance the CD4+ count. This study investigated post-HIV infection (acute to therapy phases) records of 237 patients involving repeated measurements of 17 CD4+ count clinical covariates that were found to be the strongest. The overall trends showed either downwards, upwards, or irregular behaviour. Phase-specific trends were mostly different and unimaginable, with LDH and red blood cells producing the most complex CD4+ count behaviour. The approximate optimal set points for dietary-related covariates were total protein 60-100 g/L (acute phase), <85 g/L (early phase), <75 g/L (established phase), and >85 g/L (ART phase), whilst albumin approx. 30-50 g/L (acute), >45 g/L (early and established), and <37 g/L (ART). Sodium was desirable at approx. <45 mEq/L (acute and early), <132 mEq/L (established), and >134 mEq/L (ART). Overall, desirable approximates were albumin >42 g/L, total protein <75 g/L, and sodium <137 mEq/L. We conclude that the optimal set points of the strongest CD4+ count clinical covariates tended to drift and adapt to either new ranges or overlapped with the known reference ranges to positively influence the CD4+ cell counts. Recommendation for phase-specific CD4+ cell count influence in adaptation to HIV invasion includes monitoring of the strongest covariates related to dietary conditions (sodium, albumin, and total protein), tissue oxygenation (red blood cells and its haematocrit), and hormonal control (LDH and ALP).

Cost-effectiveness of a Medical Care Coordination Program for People With HIV in Los Angeles County

Background

The Los Angeles County (LAC) Division of HIV and STD Programs implemented a medical care coordination (MCC) program to address the medical and psychosocial service needs of people with HIV (PWH) at risk for poor health outcomes.

Methods

Our objective was to evaluate the impact and cost-effectiveness of the MCC program. Using the CEPAC-US model populated with clinical characteristics and costs observed from the MCC program, we projected lifetime clinical and economic outcomes for a cohort of high-risk PWH under 2 strategies: (1) No MCC and (2) a 2-year MCC program. The cohort was stratified by acuity using social and clinical characteristics. Baseline viral suppression was 33% in both strategies; 2-year suppression was 33% with No MCC and 57% with MCC. The program cost $2700/person/year. Model outcomes included quality-adjusted life expectancy, lifetime medical costs, and cost-effectiveness. The cost-effectiveness threshold for the incremental cost-effectiveness ratio (ICER) was $100 000/quality-adjusted life-year (QALY).

Results

With MCC, life expectancy increased from 10.07 to 10.94 QALYs, and costs increased from $311 300 to $335 100 compared with No MCC (ICER, $27 400/QALY). ICERs for high/severe, moderate, and low acuity were $30 500/QALY, $25 200/QALY, and $77 400/QALY. In sensitivity analysis, MCC remained cost-effective if 2-year viral suppression was ≥39% even if MCC costs increased 3-fold.

Conclusions

The LAC MCC program improved survival and was cost-effective. Similar programs should be considered in other settings to improve outcomes for high-risk PWH.

Electronic Health Interventions to Improve Adherence to Antiretroviral Therapy in People Living With HIV: Systematic Review and Meta-Analysis

BACKGROUND

Electronic health (eHealth) is increasingly used for self-management and service delivery of HIV-related diseases. With the publication of studies increasingly focusing on antiretroviral therapy (ART) adherence, this makes it possible to quantitatively and systematically assess the effectiveness and feasibility of eHealth interventions.

OBJECTIVE

The purpose of this review was to explore the effectiveness of eHealth interventions on improving ART adherence in people living with HIV. The effects of different intervention characteristics, participant characteristics, and study characteristics were also assessed.

METHODS

We systematically searched MEDLINE (via PubMed), EMBASE, the Cochrane Central Register of Controlled Trials, and 3 conference abstract databases using search terms related to HIV, ART, adherence, and eHealth interventions. We independently screened the studies, extracted the data, and assessed the study quality and then compared the information in pairs. Articles published in English that used randomized controlled trials to assess eHealth interventions to improve ART adherence of people living with HIV were identified. We extracted the data including study characteristics, participant characteristics, intervention characteristics, and outcome measures. The Cochrane risk-of-bias tool was used to assess the risk of bias and study overall quality. Odds ratios, Cohen d, and their 95% CIs were estimated using random-effects models. We also performed multiple subgroup analyses and sensitivity analyses to define any sources of heterogeneity.

RESULTS

Among 3941 articles identified, a total of 19 studies (including 21 trials) met the inclusion criteria. We found 8 trials from high-income countries and 13 trials from low- and middle-income countries. Furthermore, at baseline, the health status of participants in 14 trials was healthy. Of the trials included, 7 of 21 used personality content, 12 of 21 used a 2-way communication strategy, and 7 of 21 used medical content. In the pooled analysis of 3937 participants (mean age: 35 years; 47.16%, 1857/3937 females), eHealth interventions significantly improved the ART adherence of people living with HIV (pooled Cohen d=0.25; 95% CI 0.05 to 0.46; P=.01). The interventions were also correlated with improved biochemical outcomes reported by 11 trials (pooled Cohen d=0.25; 95% CI 0.11 to 0.38; P<.001). The effect was sensitive to sample size (Q=5.56; P=.02) and study duration (Q=8.89; P=.003), but it could not be explained by other moderators. The primary meta-analysis result was stable in the 3 sensitivity analyses.

CONCLUSIONS

Some of the eHealth interventions may be used as an effective method to increase the ART adherence of people living with HIV. Considering that most of the trials included a small sample size and were conducted for a short duration, these results should be interpreted with caution. Future studies need to determine the features of eHealth interventions to better improve ART adherence along with long-term effectiveness of interventions, effectiveness of real-time adherence monitoring, enhancement of study design, and influences on biochemical outcomes.

Effects of individual and neighborhood socioeconomic status on antiretroviral therapy adherence: The role of adherence self-efficacy

This study aimed to examine the potential mediation effect of adherence self-efficacy on the associations between individual and neighborhood socioeconomic status and antiretroviral therapy adherence in a sample of 337 people living with HIV in South Carolina, United States. Results showed that there were no direct effects of individual or neighborhood socioeconomic status on antiretroviral therapy adherence, whereas both individual socioeconomic status and neighborhood socioeconomic status were associated with adherence self-efficacy, which in turn were related to antiretroviral therapy adherence. These findings suggest that interventions targeting adherence self-efficacy may improve antiretroviral therapy adherence among people living with HIV with low socioeconomic status or those living in socioeconomically disadvantaged neighborhoods.
