Endothelial dysfunction, a predictor of cardiovascular disease in HIV patients on antiretroviral therapy: A systematic review and meta-analysis. Thromb Res 2024; 234:101-112. [PMID: 38211378 DOI: 10.1016/j.thromres.2023.12.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2023] [Revised: 12/02/2023] [Accepted: 12/18/2023] [Indexed: 01/13/2024]
Abstract
Aim Although antiretroviral therapy (ART) is available, the rate of new HIV infections is alarming. With this trend, it is anticipated that the use of ART will continue to rise, potentially resulting in associated vascular disorders. Therefore, we aimed to examine the impact of ART on endothelial function in people living with HIV (PLHIV), a predictor of cardiovascular diseases. METHOD A comprehensive search for evidence was made on PubMed and Scopus on May 06, 2023, following the Preferred Reporting Items for Systematic Review and Meta-analysis. Cochrane and Newcastle-Ottawa quality assessment scales were used to evaluate quality, while the metaHun web tool and Review Manager version 5.4.1 were used for analysis. Subgroup, sensitivity, and publication bias were conducted for each outcome measure. RESULTS We identified 37 studies, including a sample size of 3700 with 2265 individuals on ART. The analyzed evidence showed a large significant effect of ART on vascular cell adhesion molecule-1, with a standardized mean difference (SMD) of -1.23 (95 % CI: -1.72, -0.74; p = 0.0013). Similarly, a significant medium effect of ART was observed on intercellular cell adhesion molecule-1 in PLHIV, with an SMD of -1.28 (95 % CI: -2.00, -0.56; p = 0.0231) compared to the control group. Furthermore, ART exhibited a significant but small effect on flow-mediated dilation (FMD) with an SMD of -0.40 (95 % CI: -0.62, -0.19, p = 0.0159). CONCLUSION Our findings show an improved endothelial function in PLHIV on ART, as demonstrated by reduced adhesion molecules; however, ART exhibited a small effect on FMD, thus suggesting PLHIV on ART may still be at risk of endothelial dysfunction and further cardiovascular diseases.

Plasma sVCAM-1, antiretroviral therapy and mortality in HIV-1-infected West African adults. HIV Med 2022; 23:717-726. [PMID: 35023284 DOI: 10.1111/hiv.13230] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2021] [Revised: 12/06/2021] [Accepted: 12/23/2021] [Indexed: 11/30/2022]
Abstract
OBJECTIVES We report the association between pre-antiretroviral therapy (pre-ART) soluble vascular cell adhesion molecule-1 (sVCAM-1) levels and long-term mortality in HIV-infected West African adults participating in a trial of early ART in West Africa (Temprano ANRS 12136 trial). METHODS The ART-naïve HIV-infected adults were randomly assigned to start ART immediately or defer ART until the WHO criteria were met. Participants who completed the trial follow-up were invited to participate in a post-trial phase (PTP). The PTP end-point was all-cause death. We used multivariable Cox proportional models to analyse the association between baseline sVCAM-1 and all-cause death, adjusting for ART strategy, sex, CD4 count, plasma HIV-1 RNA and peripheral blood mononuclear cell HIV-1 DNA levels. RESULTS In all, 954 adults (77% women, median CD4 count of 387 cells/μL) were randomly assigned to start ART immediately (n = 477) or to defer initiation of ART (n = 477). They were followed for a median of 5.8 years [interquartile range (IQR): 5.2-6.3]. In multivariable analysis, the risk of death was significantly associated with baseline sVCAM-1 [≥1458 vs. < 1458 ng/mL; adjusted hazard ratio = 2.86, 95% confidence interval (CI): 1.60-5.11]. The 6-year probability of death rates were 14.4% (95%CI: 9.1-22.6) and 9.4% (5.4-16.1) in patients with baseline sVCAM-1 ≥ 1458 ng/mL randomized to deferred and immediate ART, respectively, and 3.8% (2.2-6.5) and 3.5% (1.9-6.3) in patients with baseline sVCAM-1 < 1458 ng/mL randomized to deferred and immediate ART. The median difference between pre-ART and 12-month sVCAM-1 levels in patients randomized to immediate ART was -252 (IQR: -587 to -61). CONCLUSIONS Pre-ART sVCAM-1 levels were significantly associated with mortality, independently of whether ART was started immediately or deferred, but they significantly decreased after 12 months of ART.

Abstract
HIV infection is associated with comorbidities that are likely to be driven not only by HIV itself, but also by the toxicity of long-term use of antiretroviral therapy (ART). Indeed, increasing evidence demonstrates that the antiretroviral drugs used for HIV treatment have toxic effects resulting in various cellular and tissue pathologies. The blood-brain barrier (BBB) is a modulated anatomophysiological interface which separates and controls substance exchange between the blood and the brain parenchyma; therefore, it is particularly exposed to ART-induced toxicity. Balancing the health risks and gains of ART has to be considered in order to maximize the positive effects of therapy. The current review discusses the cerebrovascular toxicity of ART, with the focus on mitochondrial dysfunction. Graphical Abstract Graphical representation of the interactions between HIV, antiretroviral therapy (ART), and the blood-brain barrier (BBB).

Brain microstructural changes support cognitive deficits in HIV uninfected children born to HIV infected mothers. Brain Behav Immun Health 2020; 2:100039. [PMID: 34589830 PMCID: PMC8474176 DOI: 10.1016/j.bbih.2020.100039] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2019] [Revised: 01/20/2020] [Accepted: 01/24/2020] [Indexed: 12/22/2022] Open
Abstract
Introduction Antiretroviral therapy (ART) is considered the most effective way to prevent perinatal transmission of human immunodeficiency virus (HIV). However, there is little knowledge about the effect of ART on the brain of HIV uninfected children born to HIV infected mothers (HUC). The current study evaluated the brain's microstructural integrity, and cognitive function in HUC compared to healthy children born to normal mothers (CHNM) and HIV infected children born to HIV infected mothers (HIC) to investigate the effect of in-utero exposure of ART on cerebral gray and white matter. Materials and methods Forty nine HIC, 12 HUC and 18 CHNM underwent neuropsychological (NP) assessment and a brain MRI. Diffusion tensor imaging (DTI) data was used to generate fractional anisotropy (FA) and mean diffusivity (MD) maps. Voxel wise comparison for FA and MD was performed between three groups using an analysis of covariance (ANCOVA) including age and sex as covariates, and correction for multiple comparisons (false discovery rate (FDR), p < 0.05 with minimum extended cluster size, 150 voxels). NP test scores were also compared between three groups using ANOVA with Post Hoc Bonferroni multiple comparison corrections (p < 0.05). Significantly changed FA and MD values in different brain regions in HIC and HUC compared to CHNM were used for correlation analysis with NP test scores using Pearson's correlation. Results HIC and HUC groups showed significantly decreased NP test scores in various domain compared to CHNM. Significantly lower NP test scores was observed in HIC than those of HUC. HIC showed decreased FA and increased MD in multiple brain sites as compared to both CHNM and HUC. Decreased FA along with both increased and decreased MD in different brain regions was present in HUC compared to CHNM. Both positive and negative correlation of altered FA and MD values from different brain regions in HIC and HUC with NP test scores was observed. Conclusion The presence of brain tissue changes and neurocognitive function deficit in absence of HIV infection in HUC indicates that ART may have a detrimental impact on the developing brain. The findings of the current study underscore the need for screening of ART exposed children for neurodevelopment and cognitive abnormalities at an early stage and call for access to early interventions, and nutritional and care programs.

Abstract
Intercellular adhesion molecule 1 (ICAM-1) is a glycoprotein that participates in inflammatory and immune responses. Both cell surface and soluble ICAM-1 are significantly increased during human immunodeficiency virus (HIV) infection, and ICAM-1 has important functions in promoting inflammatory responses and enhancing HIV infectivity; however, a comprehensive summary these roles has yet to be elaborated. In this review we describe the general biological characteristics of ICAM-1, its association with HIV disease progression and promotion of HIV production, mechanisms inducing upregulation of ICAM-1, and possible intervention strategies, representing important insights in the context of HIV treatment.

Abstract
INTRODUCTION Lymphangiogenesis is the formation of new vessels from pre-existing lymphatic vessels. Data on lymphangiogenesis in the placenta of HIV-infected pre-eclamptics are sparse and the findings are conflicting. The aim of this novel study was to evaluate LYVE-1 immunoexpression in the placenta of HIV infected normotensive versus pre-eclamptic women. METHODS Placental tissue was obtained from normotensive and pre-eclamptic women stratified according to their HIV status. The pre-eclamptic group was divided into early (<34 weeks) and late (>34 weeks) onset. Immunohistochemistry utilized mouse anti-human LYVE-1 antibody and was morphometrically evaluated. RESULTS LYVE-1 immunostaining was localized within endothelium of the arterial supply and venous drainage of both conducting and exchange villi as well as within medial cells of arteries. LYVE-1 immunostained macrophage-like cells were observed within the fetal and maternal circulation. LYVE-1 immunoexpression was higher (p=0.0001) in HIV positive cohort, regardless of pregnancy and villous type. Irrespective of HIV status and pregnancy type, LYVE-1 immunoexpression was significantly elevated in the conducting compared to the exchange villi (p=0.01). LYVE-1 immunoexpression was higher in N and LOPE compared to EOPE groups for both conducting and exchange villi types respectively (p=0.0001 and p=0.006). There is a decrease of LYVE-1 expression in EOPE+ (conducting villi) and EOPE- (exchange villi) compared to N and LOPE subgroups. CONCLUSION This study provides a novel insight into an up-regulation of LYVE-1 expression in the fetal circulation of conducting and exchange villi of HIV-infected pre-eclamptics.

Abstract
PURPOSE OF REVIEW We aim to review the strengths and weaknesses of current antiretroviral therapy (ART), and describe ongoing research to address limitations to current therapy. RECENT FINDINGS Current ART is highly effective and well tolerated. As a result of a decrease in medication side-effects and pill burden, and the known health effects of uncontrolled viremia, ART is now recommended at all CD4 cell counts in the USA. Novel medications are being developed to further decrease side-effects and offer alternative options for patients with multiclass resistance. New combination pills will further decrease pill burden. SUMMARY Current treatment for HIV is characterized by highly potent oral antiretroviral medications, which are well tolerated, resulting in outstanding rates of virologic suppression in patients who are adherent to therapy. Despite the marked improvement in therapeutic options, limitations to therapy still exist including reliance on daily adherence, long-term toxicity of medications, drug-drug interactions, long-term effects of HIV even in the setting of viral suppression, high lifetime cost of treatment, and limited options for some patients with multiclass resistance. Emerging alternative treatment strategies include nucleoside reverse transcriptase inhibitor-sparing or limiting regimens and long-acting injectable combination therapy.

Abstract
PURPOSE OF REVIEW The objective of this review is to appraise recently published literature that describes the relationship between HIV, biologic and environmental risk factors, and cardiovascular disease (CVD) risk with particular emphasis on the aging HIV population and to demonstrate that these biologic and environmental factors may interact to increase the risk of CVD in the HIV population. RECENT FINDINGS The mechanisms linking HIV and CVD are multifactorial and encompass biological and 'environmental' modalities including multimorbid conditions that co-occur with HIV, immunologic alterations associated with HIV, polypharmacy (which affects adherence and increases likelihood of adverse drug-drug interactions) and healthcare disparities in CVD risk reduction by HIV status. SUMMARY Data regarding optimal treatment strategies that balance immunological restoration and CVD risk reduction are needed.
