Abstract
Low levels of high-density lipoprotein (HDL) and impaired HDL functionality have been consistently associated with increased susceptibility to infection and its serious consequences. This has been attributed to the critical role of HDL in maintaining cellular lipid homeostasis, which is essential for the proper functioning of immune and structural cells. HDL, a multifunctional particle, exerts pleiotropic effects in host defense against pathogens. It functions as a natural nanoparticle, capable of sequestering and neutralizing potentially harmful substances like bacterial lipopolysaccharides. HDL possesses antiviral activity, preventing viruses from entering or fusing with host cells, thereby halting their replication cycle. Understanding the complex relationship between HDL and the immune system may reveal innovative targets for developing new treatments to combat infectious diseases and improve patient outcomes. This review aims to emphasize the role of HDL in influencing the course of bacterial and viral infections and its and its therapeutic potential.

Abstract
People with HIV (PWH) are at elevated risk for cardiovascular diseases (CVDs), including myocardial infarction, heart failure, and sudden cardiac death, among other CVD manifestations. Chronic immune dysregulation resulting in persistent inflammation is common among PWH, particularly those with sustained viremia and impaired CD4+ T cell recovery. This inflammatory milieu is a major contributor to CVDs among PWH, in concert with common comorbidities (such as dyslipidemia and smoking) and, to a lesser extent, off-target effects of antiretroviral therapy. In this review, we discuss the clinical and mechanistic evidence surrounding heightened CVD risks among PWH, implications for specific CVD manifestations, and practical guidance for management in the setting of evolving data.

[PMID: 35080064 DOI: 10.1002/biof.1819] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2021] [Accepted: 09/02/2021] [Indexed: 11/12/2022]
Abstract
This study aimed at evaluating the serum High-density lipoprotein lipid peroxidation (HDLox) levels and their association with coronary artery disease (CAD). This case-control study comprised 572 patients with stable CAD and 281 healthy subjects with no history of cardiovascular disease (control group). Based on the results of coronary angiography, the patient group was divided into two groups: CAD- and CAD+. HDLox was measured using a fluorimetric method. The ability of HDLox and serum high-density lipoprotein cholesterol (HDL-C) to detect CAD and coronary artery stenosis ≥50% was also compared using the receiver operating characteristic (ROC) curve analysis. The CAD patients showed significantly higher serum HDLox levels, compared to the control group [1.15 (1.01-1.31) vs. 0.85 (0.62-1.06), no units, p < 0.001]. Moreover, serum HDLox levels were significantly lower in CAD- patients, compared to the CAD+ patients [1.05 (0.92-1.22) vs. 1.24 (1.12-1.35), no units, p < 0.001]. According to the results of univariate and multivariate logistic regression, the HDLox showed association with the presence of CAD (odds ratio [OR]: 1.754; 95% confidence interval [CI]: 1.564-1.968; p < 0.001) and coronary artery stenosis ≥50% (OR: 1.729; 95% CI: 1.534-1.949; p < 0.001). The results obtained from the area under the ROC curve revealed that the HDLox could better detect the risk of CAD and coronary artery stenosis ≥50% compared to serum HDL-C level. The oxidation of HDL leads to a reduction in its antioxidant function and it has a crucial role in the development of atherosclerosis. HDLox is suggested as a diagnostics biomarker for CAD.

Abstract
OBJECTIVES The aim of this study was to assess the incidence of being overweight and metabolic syndrome (MS) among people living with HIV (PHIV) in three different cross-sectional studies conducted over three different periods: 2005, 2011 and 2015. METHODS This was a multi-centre, nationwide study. Data were collected in three studies from the CISAI group - SIMOne, HIV-HY and STOPSHIV - and included a total of 3014 PHIV. Logistic regression [odds ratio (OR), 95% confidence interval (CI)] was used to account for age and gender difference among three groups when comparing MS prevalence and being overweight; potential confounders were accounted for by including them in the regression equation. RESULTS Overall, the mean age was 46.9 ± 10.2 years, and men comprised 73.3% of participants. Comparing 2005, 2011 and 2015, MS was present in 34.5%, 33.0% and 29.3% of PHIV, respectively. Adjusted OR for MS was 0.64 (95% CI: 0.52-0.78) in 2011 and 0.56 (95% CI: 0.46-0.69) in 2015 compared with 2005, while BMI (kg/m2 ) increased from 23.6 in 2005, 24.5 in 2011 and 24.5 in 2015, with a concomitant increase of being overweight from 29.4% to 39.5% to 39.6% (p < 0.0001). CONCLUSIONS In recent years, PHIV have had a significantly improved metabolic profile compared with previously, despite increasing weight and BMI.

Abstract
OBJECTIVE Low HDL cholesterol (HDL-C) is common in people living with HIV infection, which is associated with inflammation, and correlates with greater cardiovascular disease (CVD) risk. Particles of HDL are HDL subfractions, and in some general population studies, higher small HDL particle number (HDL-P) has been associated with lower CVD risk. The objective of this study was to determine whether HIV serostatus and systemic inflammation were associated with small HDL-P in the Multicenter AIDS Cohort Study (MACS). METHOD The MACS is composed of HIV-infected and HIV-uninfected men. Separate linear regression analyses were conducted to evaluate the associations between outcomes (small HDL-P, large HDL-P, total HDL-P, and HDL size) and variables of interest (interleukin-6 [IL-6], D-dimer, and intercellular adhesion molecule-1 [ICAM-1] levels), with adjustment for other CVD risk factors. RESULTS The study population included 553 HIV-infected (88.1% on current ART) and 319 HIV-uninfected men. The mean age was 52.7 years for HIV-infected men and 55.3 years for HIV-uninfected men. In separate models of the study population, higher log IL-6 was associated with lower total and small HDL-P (P < .01 for both), independent of HIV serostatus and CVD risk factors. Similar results were seen with ICAM-1. Positive HIV serostatus was associated with lower small and total HDL-P, adjusted for inflammatory markers. CONCLUSIONS Greater systemic inflammation and HIV infection both were associated with lower atheroprotective small HDL-P. This may be a potential mechanism contributing to increased cardiovascular risk among HIV-infected people.

Abstract
High-density lipoprotein (HDL) function rather than level may better predict cardiovascular disease (CVD). However, the contribution of the impaired antioxidant function of HDL that is associated with increased HDL lipid peroxidation (HDLox) to the development of clinical CVD remains unclear. We have investigated the association between serum HDLox with incident CVD outcomes in Mashhad cohort. Three-hundred and thirty individuals who had a median follow-up period of 7 years were recruited as part of the cohort. The primary end point was cardiovascular event, including myocardial infarction, stable angina, unstable angina, or coronary revascularization. In both univariate/multivariate analyses adjusted for traditional CVD risk factors, HDLox was an independent risk factor for CVD (odds ratio, 1.62; 95% confidence interval, 1.41-1.86; p < 0.001). For every increase in HDLox by 0.1 unit, there was an increase in CVD risk by 1.62-fold. In an adjusted analysis, there was a >2.5-fold increase in cardiovascular risk in individuals with HDLox higher than cutoff point of 1.06 compared to those with lower scores, suggesting HDLox > 1.06 is related to the impaired HDL oxidant function and in turn exposed to elevated risk of CVD outcomes (hazard ratio, 2.72; 95% CI, 1.88-3.94). Higher HDLox is a surrogate measure of reduced HDL antioxidant function that positively associated with cardiovascular events in a population-based cohort.

Abstract
PURPOSE OF REVIEW We comment on the role of dyslipidaemia in cardiovascular disease (CVD) in HIV-infected patients. We have discussed various risk factors, including traditional CVD risk factors, HIV-related risk factors and antiretroviral therapy (ART)-induced dyslipidaemia. RECENT FINDINGS HIV-infected individuals are prone to lipid and lipoprotein abnormalities as a result of the infection itself and the effect of ART. The older drugs used for the treatment of HIV were associated with an increased risk of these abnormalities. New therapies used to treat HIV are lipid friendly. Calculating CVD risk in the HIV population is complex due to the infection itself and the ART-related factors. The advancement in ART has helped to increase the life expectancy of HIV patients. As a result, a growing number of patients die of non-HIV related complications such as CVD, hepatic and renal disease. Outcome studies with intervention for dyslipidaemia in HIV are underway. SUMMARY The implications of the above findings suggest that all patients with HIV should undergo a CVD risk assessment before starting ART. Appropriate lipid-friendly ART regimen should be initiated along with intervention for associated CVD risk factors (e.g. lipids, hypertension and smoking).

Abstract
High-density lipoprotein (HDL) is thought to be protective against cardiovascular disease (CVD), and HDL dysfunction is considered to be a risk factor for CVD. It is unclear whether there is an association between Human T lymphotropic virus type 1 (HTLV1) infection and CVD risk. We have assessed HDL lipid peroxidation (HDLox) as a marker of HDL dysfunction and CVD risk in a subgroup of the MASHAD cohort study. One hundred and sixty two individuals including 50 subjects positive for HTLV1 infection and 112 individuals negative for HTLV1 infection were recruited. Anthropometric and biochemical parameters including serum hs-CRP, fasted lipid profile (HDL-C, LDL, triglycerides, and cholesterol), and fasting blood glucose were determined. Serum HDLox was also measured in the study participants. Multivariate analyses were used to evaluate the association between serum HDLox and HTLV1 infection. None of the traditional CVD risk factors were associated with HTLV1 infection, including serum HDL-C. However, serum HDLox was independently associated with the presence of HTLV1 infection. Logistic regression analysis showed that subjects who were positive for HTLV1 infection were also significantly more likely than uninfected individuals to have higher HDLox (odds ratio 9.35, 95%CI: 3.5-24.7; P < 0.001). HDLox was increased approximately 20% (P < 0.001) in infected subjects compared to the uninfected group. Serum HDLox is a marker of CVD risk factor and increased in individuals affected by HTLV1 infection compared to healthy subjects. © 2019 BioFactors, 45(3):374-380, 2019.

Abstract
The role of high-density lipoprotein (HDL) function and advanced glycation end products (AGEs) in HIV-related atherosclerotic cardiovascular disease (CVD) is unclear. Both glycation and oxidation (HDLox) are major modifications of HDL that can alter its composition and function. Therefore, we explored the longitudinal association of HDLox with progression of glycation, as evaluated by measurement of circulating forms of receptor for AGE that predict morbidity (soluble Receptors for Advanced Glycation Endproducts [sRAGE], endogenous secretory Receptors for Advanced Glycation Endproducts [esRAGE]), in people with HIV-1 (PWH; HIV-1) and uninfected (HIV-1) individuals.We retrospectively assessed if levels of plasma sRAGE and esRAGE and HDL function (reduced antioxidant function is associated with increased HDL lipid hydroperoxide content; HDLox) in a subset of participants (n = 80) from a prospective 3-year study (AIDS Clinical Trials Group A5078). Primary outcomes were baseline and yearly rates of change over 96 of 144 weeks (Δ) in HDLox in HIV-1 versus uninfected HIV-1 controls (noted as HIV-1).Higher baseline levels of sRAGE in PWH on effective anti-retroviral therapy and with low CVD risk, but not in HIV-1 persons, were independently associated with higher HDLox. EsRAGE, but not sRAGE, had consistent inverse relationships with ΔHDLox in both HIV-1 and HIV-1 persons at baseline. In HIV-1 but not in HIV-1 persons, ΔHDLox had positive and inverse relationships with ΔRAGE and ΔesRAGE, respectively.Glycation and oxidation of HDL may contribute to impaired HDL function present in PWH.

Abstract
Cardiovascular disease risk depends on high-density lipoprotein (HDL) function, not HDL-cholesterol. Isolevuglandins (IsoLGs) are lipid dicarbonyls that react with lysine residues of proteins and phosphatidylethanolamine. IsoLG adducts are elevated in atherosclerosis. The consequences of IsoLG modification of HDL have not been studied. We hypothesized that IsoLG modification of apoA-I deleteriously alters HDL function. We determined the effect of IsoLG on HDL structure-function and whether pentylpyridoxamine (PPM), a dicarbonyl scavenger, can preserve HDL function. IsoLG adducts in HDL derived from patients with familial hypercholesterolemia (n = 10, 233.4 ± 158.3 ng/mg) were found to be significantly higher than in healthy controls (n = 7, 90.1 ± 33.4 pg/mg protein). Further, HDL exposed to myeloperoxidase had elevated IsoLG-lysine adducts (5.7 ng/mg protein) compared with unexposed HDL (0.5 ng/mg protein). Preincubation with PPM reduced IsoLG-lysine adducts by 67%, whereas its inactive analogue pentylpyridoxine did not. The addition of IsoLG produced apoA-I and apoA-II cross-links beginning at 0.3 molar eq of IsoLG/mol of apoA-I (0.3 eq), whereas succinylaldehyde and 4-hydroxynonenal required 10 and 30 eq. IsoLG increased HDL size, generating a subpopulation of 16-23 nm. 1 eq of IsoLG decreased HDL-mediated [3H]cholesterol efflux from macrophages via ABCA1, which corresponded to a decrease in HDL-apoA-I exchange from 47.4% to only 24.8%. This suggests that IsoLG inhibits apoA-I from disassociating from HDL to interact with ABCA1. The addition of 0.3 eq of IsoLG ablated HDL's ability to inhibit LPS-stimulated cytokine expression by macrophages and increased IL-1β expression by 3.5-fold. The structural-functional effects were partially rescued with PPM scavenging.

Abstract
OBJECTIVE The role of high-density lipoprotein (HDL) function in HIV-related atherosclerotic cardiovascular disease (CVD) is unclear. HDLs isolated from HIV [HIV(+)HDL] and HIV-uninfected individuals [HIV(-)HDL] were assessed for HDL function and ability to promote monocyte-derived foam cell formation (MDFCF; a key event in HIV-related CVD) ex vivo. DESIGN/METHODS Using an established in-vitro model of atherogenesis and plasma samples from an established cross-sectional study of virologically suppressed HIV men on stable effective antiretroviral therapy and with low CVD risk (median age: 42 years; n = 10), we explored the impact of native HDL [HIV(+)HDL] on MDFCF. In this exploratory study, we selected HIV(+)HDL known to be dysfunctional based on two independent measures of impaired HDL function: antioxidant (high HDLox) ability of HDL to release apolipoprotein A-I (ApoA-I) (low HDL-ApoA-I exchange). Five healthy men matched by age and race to the HIV group were included. Given that oxidation of HDL leads to abnormal HDL function, we also compared proatherogenic effects of HIV(+)HDL vs. chemically derived HDLox. The ex-vivo atherogenesis assay was performed using lipoproteins (purchased or isolated from plasma using ultracentrifugation) and monocytes purified via negative selection from healthy donors. RESULTS HIV(+)HDL known to have reduced antioxidant function and rate of HDL/ApoAI exchange promoted MDFCF to a greater extent than HDL (33.0 vs. 26.2% foam cells; P = 0.015). HDL oxidized in vitro also enhanced foam cell formation as compared with nonoxidized HDL (P < 0.01). CONCLUSION Dysfunctional HDL in virologically suppressed HIV individuals may potentiate atherosclerosis in HIV infection by promoting MDFCF.The role of HDL function in HIV-related atherosclerotic CVD is unclear.

Abstract
Coronary artery disease (CAD) is a leading cause of morbidity and mortality worldwide. Atherosclerosis, a leading cause of CAD, is initiated by the transmigration of innate immune monocytes to inflammatory sites of deposited lipid called fatty streaks, which are present in arterial walls of medium to large arteries. The key pathogenic feature of lesions at this early stage of atherosclerosis is the maturation of monocytes which migrate into arteries to form foam cells or lipid-laden macrophages. Considerable evidence supports the hypothesis that risk of atherosclerosis is increased by chronic inflammatory conditions accompanying diseases such as rheumatoid arthritis and HIV, as well as general ageing, and that this risk is predicted by monocyte activation. While mouse models provide a good platform to investigate the role of monocytes in atherogenesis in vivo, they require genetic alteration of natural cholesterol metabolism and drastic alteration of normal mouse diets, and have limited suitability for the study of atherogenic influences of human comorbid diseases. This motivated us to develop a human in vitro model to measure the atherogenic potential of monocytes isolated from individuals with defined disease states. Currently, human in vitro models are limiting in that they evaluate monocyte transmigration and foam cell formation in isolation. Here we describe a protocol in which monocytes isolated from patient blood transmigrate across human endothelial cells into a type 1 collagen matrix, and their propensity to mature into foam cells in the presence or absence of exogenous lipid is measured. The protocol has been validated for the use of human monocytes purified from individuals with HIV infection and elderly HIV uninfected individuals. This model is versatile and allows monocyte transmigration and foam cell formation to be evaluated using either microscopy or flow cytometry as well as allowing the assessment of atherogenic factors present in serum or plasma.

Abstract
Low high-density lipoprotein cholesterol (HDL-C) levels are one of the most powerful independent negative predictors of atherosclerotic cardiovascular disease (CVD). The structure and function of HDL rather than HDL-C may more accurately predict atherosclerosis. Several HDL protein and lipid compositional changes that impair HDL function occur in inflammatory states such as atherosclerosis. HDL function is usually determined by cell based assays such as cholesterol efflux assay but these assays have numerous drawbacks lack of standardization. Cell-free assays may give more robust measures of HDL function compared to cell-based assays. HDL oxidation impairs HDL function. HDL has a major role in lipid peroxide transport and high amount of lipid peroxides is related to abnormal HDL function. Lipid-probe interactions should be considered when interpreting the results of non-enzymatic fluorescence assays for measuring the lipid oxidative state. This motivated us to develop a cell-free biochemical enzymatic method to assess HDL lipid peroxide content (HDLox) that contributes to HDL dysfunction. This method is based on the enzyme horseradish peroxidase (HRP) and the fluorochrome Amplex Red that can quantify (without cholesterol oxidase) the lipid peroxide content per mg of HDL-C. Here a protocol is describedfor determination of HDL-lipid peroxidation using the fluorochrome reagent. Assay variability can be reduced by strict standardization of experimental conditions. Higher HDLox values are associated with reduced HDL antioxidant function. The readout of this assay is associated with readouts of validated cell-based assays, surrogate measures of cardiovascular disease, systemic inflammation, immune dysfunction, and associated cardiovascular and metabolic risk phenotypes. This technical approach is a robust method to assess HDL function in human disease where systemic inflammation, oxidative stress and oxidized lipids have a key role (such as atherosclerosis).
