Associations between HIV status and self-reported hypertension in a high HIV prevalence sub-Saharan African population: a cross-sectional study
Objectives
This study examined whether HIV status and antiretroviral therapy (ART) exposure were associated with self-reported hypertension in Zimbabwe.
Design
Study data were taken from a cross-sectional, general population survey, which included HIV testing (July 2018–December 2019).
Setting
The data were collected in Manicaland Province, Zimbabwe.
Participants
9780 people aged 15 years and above were included.
Outcome measure
Self-reported hypertension was the outcome measure. This was defined as reporting a previous diagnosis of hypertension by a doctor or nurse. After weighting of survey responses by age and sex using household census data, 2 tests and logistic regression were used to explore whether HIV status and ART exposure were associated with self-reported hypertension.
Results
The weighted prevalence of self-reported hypertension was 13.6% (95% CI 12.9% to 14.2%) and the weighted prevalence of HIV was 11.1% (10.4% to 11.7%). In univariable analyses, there was no evidence of a difference in the weighted prevalence of self-reported hypertension between people living with HIV (PLHIV) and HIV-negative people (14.1%, 11.9% to 16.3% vs 13.3%, 12.6% to 14.0%; p=0.503) or between ART-exposed and ART-naive PLHIV (14.8%, 12.0% to 17.7% vs 12.8%, 9.1% to 16.4%,p=0.388). Adjusting for socio-demographic variables in logistic regression did not alter this finding (ORs:HIV status:0.88, 0.70 to 1.10, p=0.261; ART exposure:0.83, 0.53 to 1.30, p=0.411).
Conclusions
Approximately one in seven PLHIV self-reported having hypertension, highlighting an important burden of disease. However, no associations were found between HIV status or ART exposure and self-reported hypertension, suggesting that it will be valuable to focus on managing other risk factors for hypertension in this population. These findings should be fully accounted for as Zimbabwe reorients its health system towards non-communicable disease control and management.
MyTPill: study protocol for a cross-over randomised controlled trial comparing novel strategies to monitor antiretroviral adherence among HIV+ prescription opioid users
Introduction
Adherence to HIV antiretroviral therapy (ART) remains the cornerstone of HIV treatment. For individuals with suboptimal adherence, electronic adherence monitoring (EAM) technologies have become an important component of multimodal adherence support strategies. Most EAM technologies detect pillbox opening, and therefore, assume but cannot verify actual ingestion of oral medication. In contrast, a digital pill system (ID-capsule manufactured by etectRX, here named My/Treatment/Pill) measures directly ingestion of medications. Identifying the superior method to measure ART adherence would improve virological suppression by enabling the delivery of real-time interventions to support ART adherence, particularly in high-risk populations.
Methods and analysis
Cross-over, randomised trial with 1:1 variable block size randomisation comparing two EAM systems in prescription opioid-using HIV+patient on once daily oral bictegravir, emtricitabine and tenofovir alafenamide regimens and detectable viral load >200 copies/mL within 30 days of screening (n=80). The primary outcome is once daily ART adherence measurement efficacy as assessed by comparing the accuracy of each EAM system as measured by concordance of the respective EAM systems to dried blood spot ART concentrations. Secondary outcomes are the identification of multilevel factors that are prevalent in the target population most closely linked to ART non-adherence and EAM non-adherence.
Ethics and dissemination
This protocol was approved by the institutional review boards of participating sites (The Ohio State University, The Fenway Institute and the University of Miami). Data will be presented at scientific conferences and published in peer-reviewed journals.

Prevalence of, and factors associated with, alcohol use disorder among young adults (aged 15-24 years) living with HIV/AIDS in low-income and middle-income countries: protocol for a systematic review
Introduction
Alcohol use is a global driver of HIV infection and disease progression, mediated through risky behaviour and poor antiretroviral adherence. Most studies about the burden of alcohol use among people living with HIV (PLWH)/AIDS have been done in adult populations, but less is known about young people with HIV, especially in low-income and middle-income countries (LMICs), despite the high level of alcohol use in these settings. The aim of this review is to collate evidence on the prevalence of, and factors associated with, alcohol use disorder (AUD) among young adults (aged 15–24 years) living with HIV/AIDS in LMICs.
Methods and analysis
Two experienced librarians will conduct an independent article search in PubMed, PsycINFO, Embase and Web of Science databases, using relevant Medical Subject Headings terms and Boolean operators (‘AND’, ‘OR’). We will include English-language articles that were published in peer-reviewed journals from 1 January 2000, to 25 July 2022, that documented the prevalence of AUD among young people (15–24 years) living with HIV in LMICs. We shall exclude systematic review articles and qualitative studies. Two independent reviewers will screen the articles for eligibility and data will be extracted onto a preset Excel spreadsheet. Data analysis will be done using Stata V.14.0. Heterogeneity will be assessed by use of the I2 statistic and data will be pooled in meta-analyses where appropriate. Publication bias will be assessed using the funnel plot.
Ethics and dissemination
Ethical approval is not needed as this systematic review will be based on published studies. Findings from this study will be disseminated via submission for publication in a peer-reviewed journal, at conference presentations, and made available to health professionals, scientists and policy makers. Our data set can be made available on request.

Survival and health of children who are HIV-exposed uninfected: study protocol for the CHERISH (Children HIV-Exposed Uninfected – Research to Inform Survival and Health) dynamic, prospective, maternal-child cohort study
Introduction
CHERISH is designed to establish a long-term sustainable system for measurement of in utero and postnatal exposures and outcomes in children who are HIV-exposed uninfected (HEU) and HIV-unexposed to compare survival, hospitalisation, growth and neurodevelopment in the Western Cape, South Africa.
Methods and analysis
During 2022–2025, the CHERISH dynamic cohort is prospectively enrolling pregnant people with and without HIV at 24–36 weeks gestation from one urban and one rural community, following mother–child pairs, including children who are HEU (target N=1200) and HIV-unexposed (target N=600) for 3 years from the child’s birth. In-person visits occur at enrolment, delivery, 12 months, 24 months and 36 months with intervening 3-monthly telephone data collection. Children and mothers without HIV are tested for HIV at all in-person visits. Data on exposures and outcomes are collected from routine standardised healthcare documentation, maternal interview, measurement (growth and neurodevelopment) at in-person visits and linkage to the Western Cape Provincial Health Data Centre (survival and hospitalisation). A priori adverse birth outcomes, advanced maternal HIV and maternal mental health are considered potential mediators of outcome disparities in children who are HEU and will be evaluated as such in multivariable models appropriate for each outcome.
Ethics and dissemination
Mothers interested in joining the study are taken through a visual informed consent document for their and their child’s participation, with the option to consent to anonymised de-identified data being contributed to a public data repository. All data is captured directly into an electronic database using alphanumeric identifiers devoid of identifying information. The cohort study is approved by Human Research Ethics Committees of Stellenbosch University (N20/08/084), University of Cape Town (723/2021) and Western Cape Government (WC_2021_09_007). Findings will be shared with participants, participating communities, local and provincial stakeholders, child health clinicians, researchers and policymakers at local, national and international forums and submitted for publication in peer-reviewed journals.

Mitigating Infectious morbidity and Growth deficits in HIV-exposed uninfected infanTs with human Milk Oligosaccharide (MIGH-T MO): a randomised trial protocol
Introduction
Children who are HIV-exposed uninfected (HEU), that is, children who do not acquire HIV infection despite being born to mothers with HIV, have a higher risk of mortality, infectious morbidity and growth deficits than children who are HIV-unexposed uninfected (HUU). Prior research has focused on breast feeding and has pointed to changes in human milk oligosaccharides (HMOs) associated with maternal HIV that may influence the infant microbiome and thereby lead to these adverse outcomes. However, to our knowledge, no study has attempted to intervene along this pathway to reduce the occurrence of the adverse outcomes in children HEU. We will conduct a double-blind, randomised trial of a synbiotic intervention, which combines an HMO and probiotic, in breastfed infants HEU in South Africa to evaluate whether this intervention has promise to reduce excess infectious morbidity and growth faltering compared with controls.
Methods and analysis
One hundred and forty-four breastfed infants HEU, aged 4 weeks, will be 1:1 randomised to receive either a daily synbiotic or an identical-looking placebo through age 24 weeks. Infants will be followed until age 48 weeks and outcomes of infectious morbidity, growth and biological measurements (eg, microbiota, inflammation and metabolome) will be assessed. Analyses will follow intention-to-treat principles comparing the cohorts as randomised. Infants HEU will be compared across arms with respect to the occurrence of infectious morbidity and growth outcomes through 4–24 weeks and 4–48 weeks using appropriate parametric and non-parametric statistical tests. Additionally, an observational cohort of 40 breastfed infants HUU will be recruited as a comparator group with no intervention.
Ethics and dissemination
Ethical approval for this study has been obtained from the ethics committees at Columbia University and Stellenbosch University. The findings will be disseminated in publications.

Cardiovascular Disease Among Persons Living With HIV: New Insights Into Pathogenesis and Clinical Manifestations in a Global Context
Circulation, Volume 147, Issue 1, Page 83-100, January 3, 2023. Widespread use of contemporary antiretroviral therapy globally has transformed HIV disease into a chronic illness associated with excess risk for disorders of the heart and circulatory system. Current clinical care and research has focused on improving HIV-related cardiovascular disease outcomes, survival, and quality of life. In high-income countries, emphasis on prevention of atherosclerotic coronary artery disease over the past decade, including aggressive management of traditional risk factors and earlier initiation of antiretroviral therapy, has reduced risk for myocardial infarction among persons living with human immunodeficiency virus-1 infection. Still, across the globe, persons living with human immunodeficiency virus-1 infection on effective antiretroviral therapy treatment remain at increased risk for ischemic outcomes such as myocardial infarction and stroke relative to the persons without HIV. Unique features of HIV-related cardiovascular disease, in part, include the pathogenesis of coronary disease characterized by remodeling ectasia and unusual plaque morphology, the relative high proportion of type 2 myocardial infarction events, abnormalities of the aorta such as aneurysms and diffuse aortic inflammation, and HIV cerebrovasculopathy as a contributor to stroke risk. Literature over the past decade has also reflected a shift in the profile and prevalence of HIV-associated heart failure, with a reduced but persistent risk of heart failure with reduced ejection fraction and a growing risk of heart failure with preserved ejection fraction. Cardiac magnetic resonance imaging and autopsy data have emphasized the central importance of intramyocardial fibrosis for the pathogenesis of both heart failure with preserved ejection fraction and the increase in risk of sudden cardiac death. Still, more research is needed to better characterize the underlying mechanisms and clinical phenotype of HIV-associated myocardial disease in the current era. Across the different cardiovascular disease manifestations, a common pathogenic feature is that HIV-associated inflammation working through different mechanisms may amplify underlying pathology because of traditional risk and other host factors. The prevalence and phenotype of individual cardiovascular disease manifestations is ultimately influenced by the degree of injury from HIV disease combined with the profile of underlying cardiometabolic factors, both of which may differ substantially by region globally.
Safety and efficacy of long-acting intramuscular cabotegravir and rilpivirine in adults with HIV-1 infection: a systematic review and meta-analysis protocol
Background
Current antiretroviral regimens have, for the most part, achieved optimal antiretroviral efficacy and tolerability, transforming HIV infection from a deadly disease into a manageable chronic condition. However, adherence to daily oral drug intake remains an issue, as it is the most important determinant for sustained viral suppression and prevention of the emergence of drug-resistant viral strains. The long-acting injection antiretroviral cabotegravir and rilpivirine combination, a novel drug delivery approach, is about to revolutionise the therapy for people living with HIV. In this protocol, we aim to generate a clinically useful summary of the interventions based on their efficacy.
Methods and analysis
We searched the literature for eligible studies published from inception up to 16 August 2022 through PubMed, EMBASE, Cochrane Library, Scopus and ClinicalTrials.gov. Two methodologically trained researchers will select the qualified studies for data extraction independently. Cochrane Risk of Bias tool will be used to assess the risk of bias in included studies. Statistical heterogeneity will be computed by Cochrane X2 and I2 tests. Sensitivity analysis will be conducted to evaluate the stability of the results. Publication biases will be evaluated by Begg’s and Egger’s tests. The quality of evidence will be assessed by the Grading of Recommendations Assessment, Development and Evaluation system. The RevMan V.5.3 and Stata V.14.0 software will be applied for statistical analyses.
Ethics and dissemination
Ethical approval will not be required for this systematic review because the data used are not linked to the individual patient. The results of this review will be disseminated by being published in a peer-reviewed journal.
