Abstract
PURPOSE To figure out the roles of tear inflammatory cytokines in Ocular graft-versus-host disease (oGVHD) symptoms by analyzing tear cytokine levels and related factors. METHODS This prospective study involved 27 post-HSCT patients and 19 controls with dry eye disease. Analyses included tear cytokine (IL-6, IL-10, and TNF-α), ocular surface evaluation, and conjunctival impression cell examination. Tear cytokine levels were evaluated in three grades of corneal epithelial lesions. The study also analyzed the correlation between tear cytokine levels and ocular surface parameters. Tear cytokine levels were then used in a Receiver Operating Characteristic (ROC) curve and linear regression model to predict oGVHD related factors. RESULTS IL-6 has good diagnostic efficacy in oGVHD related dry eye. Elevated levels of tear IL-6 and TNF-α were observed in the group with severe corneal epithelial lesions. IL-6 levels were positively correlated with corneal fluorescein staining (CFS), eyelid margin hyperemia, conjunctival lesions, and meibum secretion. IL-6 showed excellent predictive ability with Area Under the Curve (AUC) values all greater than 0.70 (p < 0.05). IL-10 and TNF-α were negatively correlated with the meibomian gland proportion and conjunctival goblet cell (GC) density, while TNF-α was positively correlated with CFS and eyelid margin hyperemia. CONCLUSION Dry eye symptoms related to ocular GVHD, can be partly diagnosed and assessed using various tear cytokine level detection methods.

Abstract
Rheumatoid arthritis (RA) is a chronic inflammatory disease mainly affecting the peripheral diarthrodial joints symmetrically and also presenting many extra-articular manifestations. Morbidity and mortality in RA patients are higher compared to the general population. Cardiovascular (CV) disease is one of the most common causes of death in these patients. Classical or traditional risk factors for atherosclerosis development occur more frequently in RA patients compared to those without this condition. Studies have showed that RA patients often present comorbidities such as hypertension, dyslipidemia, diabetes mellitus and obesity. However, the high incidence of CV events occurring in RA patients is not explained by the presence of traditional risk factors. Systemic inflammation, as it is expressed with the presence of proinflammatory cytokines and increased acute phase reactants, may contribute to the development of premature atherosclerosis in these patients. In this review, we explore the risk factors for CV disease, the generation of dyslipidemia, the lipid paradox and the role of systemic inflammation in the atherosclerotic process in RA. We discuss also the role of early therapeutic intervention that suppresses inflammation which may have beneficial effects on CV disease in RA patients.

Abstract
Climate change and population densities accelerated transmission of highly pathogenic viruses to humans, including the Crimean-Congo haemorrhagic fever virus (CCHFV). Here we report that the Low Density Lipoprotein Receptor (LDLR) is a critical receptor for CCHFV cell entry, playing a vital role in CCHFV infection in cell culture and blood vessel organoids. The interaction between CCHFV and LDLR is highly specific, with other members of the LDLR protein family failing to bind to or neutralize the virus. Biosensor experiments demonstrate that LDLR specifically binds the surface glycoproteins of CCHFV. Importantly, mice lacking LDLR exhibit a delay in CCHFV-induced disease. Furthermore, we identified the presence of Apolipoprotein E (ApoE) on CCHFV particles. Our findings highlight the essential role of LDLR in CCHFV infection, irrespective of ApoE presence, when the virus is produced in tick cells. This discovery holds profound implications for the development of future therapies against CCHFV.

Abstract
Rheumatoid arthritis (RA) is a systemic inflammatory disorder that characteristically affects the joints. RA has extra-articular manifestations that can impact multiple organ systems including the heart, lungs, eyes, skin, and brain. Cardiovascular involvement is a leading cause of mortality in RA. Cardiovascular manifestations of RA include accelerated atherosclerosis, heart failure, pericarditis, myocarditis, endocarditis, rheumatoid nodules, and amyloidosis. Inflammation is an important mediator of endothelial dysfunction and is a key driver of cardiovascular risk and complications in patients with RA. Prompt identification of cardiac pathologies in patients with RA is essential for appropriate management and treatment. Choosing the most appropriate treatment regimen is based on individual patient factors. In this article, we provide a comprehensive review of the epidemiology, pathophysiology, clinical manifestations, diagnosis, and medical management of cardiovascular manifestations of RA. We also discuss the relationship between anti-rheumatic medications, specifically non-steroidal anti-inflammatory drugs, corticosteroids, methotrexate, statins, tumor necrosis factor inhibitors, interleukin-6 inhibitors, Janus kinase inhibitors, and cardiovascular disease.

Knock-in mice expressing a humanized arachidonic acid 15-lipoxygenase (Alox15) carry a partly dysfunctional erythropoietic system. Cell Mol Biol Lett 2023; 28:97. [PMID: 38030974 PMCID: PMC10685687 DOI: 10.1186/s11658-023-00511-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Accepted: 11/07/2023] [Indexed: 12/01/2023] Open
Abstract
Arachidonic acid 15-lipoxygenases (ALOX15) play a role in mammalian erythropoiesis but they have also been implicated in inflammatory processes. Seven intact Alox genes have been detected in the mouse reference genome and the mouse Alox15 gene is structurally similar to the orthologous genes of other mammals. However, mouse and human ALOX15 orthologs have different functional characteristics. Human ALOX15 converts C20 polyenoic fatty acids like arachidonic acid mainly to the n-6 hydroperoxide. In contrast, the n-9 hydroperoxide is the major oxygenation product formed by mouse Alox15. Previous experiments indicated that Leu353Phe exchange in recombinant mouse Alox15 humanized the catalytic properties of the enzyme. To investigate whether this functional humanization might also work in vivo and to characterize the functional consequences of mouse Alox15 humanization we generated Alox15 knock-in mice (Alox15-KI), in which the Alox15 gene was modified in such a way that the animals express the arachidonic acid 15-lipoxygenating Leu353Phe mutant instead of the arachidonic acid 12-lipoxygenating wildtype enzyme. These mice develop normally, they are fully fertile but display modified plasma oxylipidomes. In young individuals, the basic hematological parameters were not different when Alox15-KI mice and outbred wildtype controls were compared. However, when growing older male Alox15-KI mice develop signs of dysfunctional erythropoiesis such as reduced hematocrit, lower erythrocyte counts and attenuated hemoglobin concentration. These differences were paralleled by an improved ex vivo osmotic resistance of the peripheral red blood cells. Interestingly, such differences were not observed in female individuals suggesting gender specific effects. In summary, these data indicated that functional humanization of mouse Alox15 induces defective erythropoiesis in aged male individuals.

Abstract
Rheumatoid arthritis (RA) is an autoimmune inflammatory disease, of which the leading cause of death is cardiovascular disease (CVD). The levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-c), and high-density lipoprotein cholesterol (HDL-c) in RA decrease especially under hyperinflammatory conditions. It is conflictive with the increased risk of CVD in RA, which is called "lipid paradox". The systemic inflammation may explain this apparent contradiction. The increased systemic proinflammatory cytokines in RA mainly include interleukin-6(IL-6)、interleukin-1(IL-1)and tumor necrosis factor alpha(TNF-α). The inflammation of RA cause changes in the subcomponents and structure of HDL particles, leading to a weakened anti-atherosclerosis function and promoting LDL oxidation and plaque formation. Dysfunctional HDL can further worsen the abnormalities of LDL metabolism, increasing the risk of cardiovascular disease. However, the specific mechanisms underlying lipid changes in RA and increased CVD risk remain unclear. Therefore, this article comprehensively integrates the latest existing literature to describe the unique lipid profile of RA, explore the mechanisms of lipid changes, and investigate the impact of lipid changes on cardiovascular disease.

Abstract
Green microalgae are single-celled eukaryotic organisms that, in recent years, are becoming increasingly important in the nutraceutical, cosmetic, and pharmaceutical fields because of their high content of bioactive compounds. In this study, a particular green microalga was isolated from freshwater highland lakes of Ecuador and morphologically and molecularly identified as Chlamydomonas agloeformis (ChA), and it was studied for nutritional and nutraceutical properties. The phenolic composition and the fatty acids profile of lyophilized cells were determined. The methanolic extract was analyzed for the phenolic compounds profile and the antioxidant capacity by means of in vitro tests. Finally, Human Microvascular Endothelial Cells (HMEC-1) were exploited to explore the capacity of ChA to reduce the endothelial damage induced by oxidized LDL-mediated oxidative stress. The extract showed a good antioxidant ability thanks to the high content in polyphenolic compounds. The observed decrease in HMEC-1 cells endothelial damage also was probably due to the antioxidant compounds present in the extract. Based on the outcomes of our in vitro assays, ChA demonstrated to be a promising source of bioactive compounds possessing exceptional antioxidant capacities which make it a prospective functional food.

Abstract
Recently, green microalgae have gained importance due to their nutritional and bioactive compounds, which makes them some of the most promising and innovative functional foods. The aim of this study was to evaluate the chemical profile and the in vitro antioxidant, antimicrobial and antimutagenic activity of an aqueous extract of the green microalga Ettlia pseudoalveolaris, obtained from the freshwater lakes of the Ecuadorian Highlands. Human microvascular endothelial cells (HMEC-1) were used to determine the ability of the microalga to reduce the endothelial damage caused by hydrogen peroxide-induced oxidative stress. Furthermore, the eukaryotic system Saccharomyces cerevisiae was used to evaluate the possible cytotoxic, mutagenic and antimutagenic effect of E. pseudoalveolaris. The extract showed a notable antioxidant capacity and a moderate antibacterial activity mostly due to the high content in polyphenolic compounds. It is likely that the antioxidant compounds present in the extract were also responsible for the observed reduction in endothelial damage of HMEC-1 cells. An antimutagenic effect through a direct antioxidant mechanism was also found. Based on the results of in vitro assays, E. pseudoalveolaris proved to be a good source of bioactive compounds and antioxidant, antibacterial and antimutagenic capacities making it a potential functional food.

Liu KS, Yang YY, Hwang KL, Wu HJ. Investigating the Current Status of SARS-CoV-2 Antibodies in Hospital Staff. Pathogens 2023; 12:pathogens12050688. [PMID: 37242357 DOI: 10.3390/pathogens12050688] [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: 03/24/2023] [Revised: 04/26/2023] [Accepted: 05/04/2023] [Indexed: 05/28/2023] Open
Abstract
The coronavirus disease 2019 (COVID-19) pandemic caused by SARS-CoV-2 had reported over 676 million cases by March 2023. The main aim of this study is to investigate whether the levels of anti-S and anti-N antibodies could precisely indicate the degree of protection against SARS-CoV-2 and affect the probability or time of contracting COVID-19. In this study, a serosurveillance study was conducted in healthcare workers (HCWs) at a regional hospital in Taiwan to evaluate their antibody levels based on infection and vaccination status. Of 245 HCWs enrolled, all have been vaccinated prior to infection. Of these, 85 participants were infected by SARS-CoV-2, while 160 participants were not infected at the time of blood sample collection. The level of anti-SARS-CoV-2 S antibody was significantly higher in the infected HCWs than in the non-infected participants (p < 0.001). It is worth noting that the mean duration between the administration of the last dose of the vaccine and the occurrence of SARS-CoV-2 infection was 5.61 ± 2.95 months. Our follow-up survey revealed that the non-infected group had significantly higher levels of antibodies compared to the infected group (all p < 0.001). In conclusion, this study suggests that the level of antibodies could serve as a reflection of the protective efficacy against SARS-CoV-2 infection. It has the implication for vaccine decision-making policies in the future.

Roos K, Berkholz J. LDL Affects the Immunomodulatory Response of Endothelial Cells by Modulation of the Promyelocytic Leukemia Protein (PML) Expression via PKC. Int J Mol Sci 2023; 24:ijms24087306. [PMID: 37108469 PMCID: PMC10138343 DOI: 10.3390/ijms24087306] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2023] [Revised: 04/04/2023] [Accepted: 04/10/2023] [Indexed: 04/29/2023] Open
Abstract
In addition to its function as an intravascular lipid transporter, LDL also triggers signal transduction in endothelial cells (ECs), which, among other things, trigger immunomodulatory cascades, e.g., IL-6 upregulation. However, the molecular mechanisms of how these LDL-triggered immunological responses in ECs are realized are not fully understood. Since promyelocytic leukemia protein (PML) plays a role in promoting inflammatory processes, we examined the relationship between LDL, PML, and IL-6 in human ECs (HUVECs and EA.hy926 cells). RT-qPCR, immunoblotting, and immunofluorescence analyses showed that LDL but not HDL induced higher PML expression and higher numbers of PML-nuclear bodies (PML-NBs). Transfection of the ECs with a PML gene-encoding vector or PML-specific siRNAs demonstrated PML-regulated IL-6 and IL-8 expression and secretion after LDL exposure. Moreover, incubation with the PKC inhibitor sc-3088 or the PKC activator PMA showed that LDL-induced PKC activity leads to the upregulation of PML mRNA and PML protein. In summary, our experimental data suggest that high LDL concentrations trigger PKC activity in ECs to upregulate PML expression, which then increases production and secretion of IL-6 and IL-8. This molecular cascade represents a novel cellular signaling pathway with immunomodulatory effects in ECs in response to LDL exposure.

Abstract
OBJECTIVES To evaluate the relationship between soluble vascular cell adhesion molecule-1 (sVCAM-1), soluble intracellular adhesion molecule-1 (sICAM-1), and lipid levels in rheumatoid arthritis (RA) patients with and without carotid plaque (CP). METHODS Cross-sectional study nested of a RA cohort. RA patients without a previous cardiovascular event or statins' therapy, aged 40-75 years were recruited at an outpatient cardio-rheumatology clinic. Carotid ultrasound was performed in all study subjects. RA patients with CP were included and matched to RA patients without CP by age, gender, and traditional cardiovascular risk factors. Blood samples were drawn at the time of recruitment to measure sVCAM-1, sICAM-1, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and lipid levels. Correlations between cell adhesion molecules, disease activity indexes, ESR and CRP with lipid levels were assessed with Spearman's correlation coefficient (rs). RESULTS We included 71 RA patients, 37 with CP and 34 without CP. RA (n = 71) patients had a moderate negative correlation of sVCAM-1 with total cholesterol (TC) (rs = - 0.366, p = 0.002) and low-density lipoprotein (LDL) (rs = - 0.316, p = 0.007), and a small negative correlation with high-density lipoprotein (rs = - 0.250, p = 0.036). ESR showed a small negative correlation with LDL (rs = - 0.247, p = 0.038). Patients with CP had a moderate negative correlation between sVCAM and TC (rs = - 0.405, p = 0.013). Patients without CP showed a moderate negative correlation between sVCAM with TC (rs = - 0.364, p = 0.034) and LDL (rs = - 0.352, p = 0.041), and sICAM with VLDL (rs = - 0.343, p = 0.047). CONCLUSIONS RA patients showed an inverse association of sVCAM-1 and lipid levels. More studies are needed to define the precise role of sVCAM-1 in the lipid paradox of RA.

Abstract
Obviously, immune cells like T cells and macrophages play a major role in rheumatoid arthritis (RA). On one hand, the breakdown of immune homeostasis directly induces systemic inflammation; on the other hand, these cells initiate and perpetuate synovitis and tissue damages through the interaction with fibroblast-like synoviocytes (FLS). In recent years, the pathological link between metabolic disorders and immune imbalance has received increasing attention. High energy demand of immune cells leads to the accumulation of metabolic byproducts and inflammatory mediators. They act on various metabolism-sensitive signal pathways as well as relevant transcription factors, such as HIF-1α, and STATs. These molecular events will impact RA-related effectors like circulating immune cells and joint-resident cells in return, allowing the continuous progression of systemic inflammation, arthritic manifestations, and life-threatening complications. In other words, metabolic complications are secondary pathological factors for the progression of RA. Therefore, the status of energy metabolism may be an important indicator to evaluate RA severity, and in-depth explorations of the mechanisms underlying the mystery of how RA-related metabolic disorders develop will provide useful clues to further clarify the etiology of RA, and inspire the discovery of new anti-rheumatic targets. This article reviews the latest research progress on the interactions between immune and metabolism systems in the context of RA. Great importance is attached to the changes in certain pathways controlling both immune and metabolism functions during RA progression.

Abstract
BACKGROUND Feminizing hormonal therapy (FHT) and HIV potentially alter cardiovascular disease (CVD) risk in transgender women (TW). METHODS TW were enrolled in Los Angeles, California and Houston, Texas and frequency-matched to Multicenter AIDS Cohort Study cisgender men (CM) on age, race, substance use, and abacavir use. Biomarkers of CVD risk and inflammation were assessed via ELISA. Wilcoxon rank sum and Fisher's exact tests compared TW and CM. Multivariable linear regression assessed factors associated with biomarker concentrations. RESULTS TW (HIV+ n = 75, HIV- n = 47) and CM (HIV+ n = 40, HIV- n = 40) had mean age 43-45 years; TW/CM were 90%/91% non-Hispanic Black, Hispanic, or Multiracial, 26%/53% obese, and 34%/24% current smokers; 67% of TW were on FHT. Among people with HIV (PWH), TW had higher median extracellular newly-identified receptor for advanced glycation end-products (EN-RAGE), lipoprotein-associated phospholipase A2 (LpPLA2), oxidized low-density lipoprotein (oxLDL), soluble tumor necrosis factor receptor type (sTNFR) I/II, interleukin (IL)-8 and plasminogen activator inhibitor (PAI)-1, but lower soluble CD14, von Willebrand factor (vWF) and endothelin (ET)-1 levels than CM. Findings were similar for participants without HIV (all P < 0.05). In multivariable analysis, TW had higher EN-RAGE, IL-6, IL-8, P selectin, PAI-1, oxLDL and sTNFRI/II concentrations, and lower vWF, independent of HIV serostatus and current FHT use. Both being a TW and a PWH were associated with lower ET-1. CONCLUSIONS Compared to matched cisgender men, trans women have altered profiles of biomarkers associated with systemic inflammation and CVD. Further work is needed to decipher the contributions of FHT to CVD risk in TW with HIV.

Brain Res 2022; 1795:148080. [PMID: 36088960 DOI: 10.1016/j.brainres.2022.148080] [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: 05/23/2022] [Revised: 09/02/2022] [Accepted: 09/05/2022] [Indexed: 11/29/2022]
Abstract
BACKGROUND AND PURPOSE A high plasma concentration of proprotein convertase subtilisin/kexin type 9 is characteristic of a prothrombotic state in cardiovascular diseases. Elevated inflammatory markers, such as interleukin-6, are associated with worse outcomes after ischemic stroke. We aimed to study the role of plasma PCSK9 and IL-6 in acute ischemic stroke with dyslipidemia. METHODS We divided 123 enrolled patients with first-ever acute ischemic stroke into normotensive and high blood pressure groups and further into high and low pulse pressure subgroups. Clinical characteristics and inflammatory and metabolic parameters, including plasma PCSK9 and IL-6, were recorded. RESULTS After the analysis of the normotensive and BP groups, there were positive correlations between PP and carotid stenosis (P = 0.031) and plaque numbers (P = 0.013) and between National Institute of Health Stroke Scale scores (P = 0.019) and carotid stenosis severity (P = 0.021) and resistance index (P = 0.04). There was a significant association between plasma cholesterol and PCSK9 (P = 0.044) in the low PP subgroup and IL-6 (P = 0.042) in the high PP subgroup. CONCLUSIONS Our findings indicated that plasma PCSK9 levels were associated with the low PP subgroup, while IL-6 was associated with the high PP subgroup. Dyslipidemia control is also necessary for those who had a stroke and who have high PP. Further investigation to assess the role of PCSK9 and IL-6 in patients with stroke is required for early treatment and secondary prevention.

Lipoprotein oxidation may underlie the paradoxical association of low cholesterol with coronary atherosclerotic risk in rheumatoid arthritis. J Autoimmun 2022; 129:102815. [PMID: 35366608 DOI: 10.1016/j.jaut.2022.102815] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2022] [Revised: 03/09/2022] [Accepted: 03/10/2022] [Indexed: 12/23/2022]
Abstract
OBJECTIVE To compare coronary plaque burden, proatherogenic cytokines, oxidized low-density lipoprotein (oxLDL), anti-oxLDL antibodies, lipoprotein(a)-cholesterol, and their relationships in patients with rheumatoid arthritis with low-density lipoprotein cholesterol (LDL-C)<1.8 mmol/L versus ≥1.8 mmol/L. Also, to study differences in inflammation and proprotein convertase subtilisin/kexin type-9 (PCSK9), which impacts LDL clearance, in patients with low versus high LDL-C. METHODS Computed tomography angiography evaluated coronary plaque (noncalcified, partially calcified, fully calcified, and high-risk plaque) in 150 patients from a single-center observational cohort. Ox-LDL, anti-oxLDL IgG, lipoprotein(a)-cholesterol, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), interleukin-6, tumor necrosis factor-α (TNF-α) and PCSK9 were measured. Analyses adjusted for Framingham general cardiovascular risk score, statin use, and high-density lipoprotein cholesterol. RESULTS Patients with LDL-C<1.8 mmol/L versus ≥1.8 mmol/L demonstrated: 1) higher likelihood of per-segment plaque (adjusted-OR = 1.67 [95%CI = 1.10-2.55], p = 0.017) and high-risk plaque presence (adjusted-OR 2.78 [95%CI = 1.06-7.29], p = 0.038); 2) greater anti-oxLDL titers (p = 0.020), which positively associated with TNF-α and likelihood of noncalcified, partially calcified and high-risk plaque presence only in patients with LDL-C<1.8 mmol/L (all p-for-interaction≤0.046); 3) increased lipoprotein(a)-cholesterol content (10.33% [8.11-12.54] versus 6.68% [6.10-7.25], p < 0.001), which positively associated with oxLDL (p < 0.001) and anti-oxLDL (p = 0.036); 4) higher interleukin-6 and PCSK9. No differences in CRP, ESR, or oxLDL were observed. CONCLUSION RA patients with LDL-C<1.8 mmol/L had more coronary plaque, higher anti-oxLDL titers and anti-oxLDL associated with plaque only in this group. It is possible the observed paradoxical association of low LDL-C with greater atherosclerosis may be related to higher production of the oxidation-prone lipoprotein(a)-cholesterol and anti-oxLDL antibodies, resulting in increased vascular LDL uptake and plaque formation.

Abstract
Abnormal hematopoiesis advances cardiovascular disease by generating excess inflammatory leukocytes that attack the arteries and the heart. The bone marrow niche regulates hematopoietic stem cell proliferation and hence the systemic leukocyte pool, but whether cardiovascular disease affects the hematopoietic organ's microvasculature is unknown. Here we show that hypertension, atherosclerosis and myocardial infarction (MI) instigate endothelial dysfunction, leakage, vascular fibrosis and angiogenesis in the bone marrow, altogether leading to overproduction of inflammatory myeloid cells and systemic leukocytosis. Limiting angiogenesis with endothelial deletion of Vegfr2 (encoding vascular endothelial growth factor (VEGF) receptor 2) curbed emergency hematopoiesis after MI. We noted that bone marrow endothelial cells assumed inflammatory transcriptional phenotypes in all examined stages of cardiovascular disease. Endothelial deletion of Il6 or Vcan (encoding versican), genes shown to be highly expressed in mice with atherosclerosis or MI, reduced hematopoiesis and systemic myeloid cell numbers in these conditions. Our findings establish that cardiovascular disease remodels the vascular bone marrow niche, stimulating hematopoiesis and production of inflammatory leukocytes.

Ling Y, Weng H, Tang S. The relationship between IL-6 levels and the angiographic severity of coronary artery disease following percutaneous coronary intervention in acute coronary syndrome patients. BMC Cardiovasc Disord 2021; 21:578. [PMID: 34861824 PMCID: PMC8642871 DOI: 10.1186/s12872-021-02406-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2021] [Accepted: 11/26/2021] [Indexed: 12/27/2022] Open
Abstract
Background The present investigation was developed for the exploration of the association between IL-6 levels and acute coronary syndrome (ACS) findings upon angiographic evaluation. Methods A retrospective review of 346 patients suffering from chest discomfort that underwent coronary angiography was performed. The SYNergy between Percutaneous Coronary Intervention with TAXus and cardiac surgery (SYNTAX) score (SS) and SS II were used to gauge ACS severity, with ACS patients being stratified into two groups based on an SS value of 22 and the median SS II value. Associations between IL-6 levels and SS or SS II values were assessed through Spearman's correlation analyses, and independent predictors of intermediate-high SS or high SS II were identified via a multivariate logistic regression approach. A receiver operating characteristic (ROC) curve was employed to explore of the predictive value of IL-6 levels. Results IL-6 was positively correlated with both SS (r = 0.479, P < 0.001) and SS II (r = 0.305, P < 0.001). Moreover, IL-6 levels were independently predictive of intermediate-high SS and high SS II values. ROC curves further demonstrated that IL-6 was able to predict intermediate-high SS and high SS II, with area under the curve (AUC) values of 0.806 and 0.624, respectively. Conclusion IL-6 levels are closely linked to the extent of coronary artery disease in ACS patients undergoing percutaneous coronary intervention. IL-6 levels may thus serve as a valuable and non-invasive biomarker of high-risk ACS patients.

JOURNAL OF ETHNOPHARMACOLOGY 2021; 278:114278. [PMID: 34087397 DOI: 10.1016/j.jep.2021.114278] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/26/2021] [Revised: 05/18/2021] [Accepted: 05/30/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Atherosclerosis (AS) plays an important role in the pathogenesis of cardiovascular and cerebrovascular diseases. Danggui-Shaoyao-San (DSS) is not only a representative Chinese formula to treat gynecological disorder, but also found its use in AS-related diseases. However, the active ingredients and the anti-AS effects are vague yet. AIM OF THE STUDY An integrated strategy combined ultrahigh-performance liquid chromatography quadrupole-Orbitrap high-resolution mass spectrometry (UHPLC-Q-Orbitrap-HRMS), network pharmacology and experiments was carried out to investigate the potential materials and pharmacological mechanisms of DSS for AS. MATERIALS AND METHODS First, UHPLC-Q-Orbitrap-HRMS was applied to identify the active compositions of DSS. Then, the putative targets of DSS relevant to AS were predicted from TCMSP and BATMAN, which were further determined through bioinformatic analyses, including protein-protein interactions (PPI), Gene Ontology (GO), and Kyoto Encyclopedia of Genes and Genomes (KEGG). Finally, Western blot, qPCR and ELISA were carried out for target validation in human umbilical vein endothelial cells (HUVECs). RESULTS A total of 37 active ingredients of DSS, connecting 47 key targets were identified. The functional enrichment showed that DSS may treat AS through regulating a series of signaling pathways which involving inflammatory responses, immune systems and metabolism. The in vitro experiment revealed that DSS ameliorated AS mainly through anti-inflammatory effects, by reducing the levels of vascular cell adhesion molecule-1 (VCAM1), intercellular adhesion molecule-1 (ICAM1), IL-6, TNF-α, cyclooxygenase-2 (Cox-2) and IL-1β. DSS also inhibited the phosphorylation of IκB-α, NF-κB (p65), p38 and JNK in lipopolysaccharide (LPS)-induced HUVEC injury model. Moreover, as the main bioactive compounds of DSS, paeoniflorin (PF), ferulic acid (FA) and pachymic acid (PA) inhibited IL-6 and TNF-α secretion as well as IκB-α, NF-κB (p65), p38 and JNK activation. All these findings were consistent with the predicted targets and pathways. CONCLUSION Collectively, the basic pharmacological effects and relevant mechanisms of DSS in the treatment of AS were revealed. The results suggest that DSS is a potential drug for AS treatment, and PF, FA, PA may be the core compositions contributing to the pharmacological function of this formula.

Abstract
Background The numbers of confirmed cases of coronavirus disease 2019 (COVID-19) and COVID-19 related deaths are still increasing, so it is very important to determine the risk factors of COVID-19. Dyslipidemia is a common complication in patients with COVID-19, but the association of dyslipidemia with the severity and mortality of COVID-19 is still unclear. The aim of this study is to analyze the potential association of dyslipidemia with the severity and mortality of COVID-19. Methods We searched the PubMed, Embase, MEDLINE, and Cochrane Library databases for all relevant studies up to August 24, 2020. All the articles published were retrieved without language restriction. All analysis was performed using Stata 13.1 software and Mantel–Haenszel formula with fixed effects models was used to compare the differences between studies. The Newcastle Ottawa scale was used to assess the quality of the included studies. Results Twenty-eight studies involving 12,995 COVID-19 patients were included in the meta-analysis, which was consisted of 26 cohort studies and 2 case–control studies. Dyslipidemia was associated with the severity of COVID-19 (odds ratio [OR] = 1.27, 95% confidence interval [CI] 1.11–1.44, P = 0.038, I2 = 39.8%). Further, patients with dyslipidemia had a 2.13-fold increased risk of death compared to patients without dyslipidemia (95% CI 1.84–2.47, P = 0.001, I2 = 66.4%). Conclusions The results proved that dyslipidemia is associated with increased severity and mortality of COVID-19. Therefore, we should monitor blood lipids and administer active treatments in COVID-19 patients with dyslipidemia to reduce the severity and mortality.

Abstract
While the most common manifestations associated with rheumatoid arthritis (RA) are synovial damage and inflammation, the systemic effects of this autoimmune disorder are life-threatening, and are prevalent in 0.5–1% of the population, mainly associated with cardiovascular disorders (CVDs). Such effects have been instigated by an altered lipid profile in RA patients, which has been reported to correlate with CV risks. Altered lipid paradox is related to inflammatory burden in RA patients. The review highlights general lipid pathways (exogenous and endogenous), along with the changes in different forms of lipids and lipoproteins in RA conditions, which further contribute to elevated risks of CVDs like ischemic heart disease, atherosclerosis, myocardial infarction etc. The authors provide a deep insight on altered levels of low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and triglycerides (TGs) in RA patients and their consequence on the cardiovascular health of the patient. This is followed by a detailed description of the impact of anti-rheumatoid therapy on the lipid profile in RA patients, comprising DMARDs, corticosteroids, anti-TNF agents, anti-IL-6 agents, JAK inhibitors and statins. Furthermore, this review elaborates on the prospects to be considered to optimize future investigation on management of RA and treatment therapies targeting altered lipid paradigms in patients.

Abstract
Aims This study investigated the association of circulating ceramides in patients with comorbid acute coronary syndrome and type 2 diabetes mellitus (ACS-DM). Methods A total of 761 patients with coronary heart disease who were admitted to the Department of Cardiology at the Chinese PLA General Hospital from March to August 2018 were enrolled in this study. Of these 761 patients, 282 were diagnosed with acute coronary syndrome (ACS). We selected 65 patients with ACS-DM (ACS-DM group; mean age 64.88 years; 38 men) and 65 patients with ACS but without any comorbidities (ACS group; mean age 64.68 years; 38 men); the two groups were matched by age and sex. We determined four circulating ceramides in 130 plasma samples: Cer(d18:1/16:0), Cer(d18:1/18:0), Cer(d18:1/24:1), and Cer(d18:1/24:0). The ceramides in plasma samples from patients with ACS and those from patients with ACS-DM were compared. Pearson correlation coefficients between individual ceramides and traditional cardiovascular risk factors for the whole study population were calculated. Multiple logistic regression models were used to evaluate the relativity between the ceramide and ACS-DM. Results Compared with the ACS group, the levels of Cer(d18:1/16:0), Cer(d18:1/18:0), and Cer(d18:1/24:1) and their ratios to Cer(d18:1/24:0) were higher in the ACS-DM group and Cer(d18:1/24:0) was lower in the ACS-DM group (P < 0.05). Correlation analysis demonstrated mild-to-moderate correlations of ceramide and traditional cardiovascular risk factors. There were relatively strong correlations of Cer(d18:1/18:0) and Cer(d18:1/24:1) with C-reactive protein, blood lipids, fasting blood glucose, and glycated hemoglobin A1c. In multiple logistic regression models, Cer(d18:1/18:0) [odds ratio (OR) 2.396; 95% confidence interval (CI) 1.103–5.205; P = 0.027], Cer(d18:1/24:1) (OR 2.826; 95% CI 1.158–6.896; P = 0.023), Cer(d18:1/18:0)/Cer(d18:1/24:0) (OR 2.242; 95% CI 1.103–4.555; P = 0.026), and Cer(d18:1/24:1)/Cer(d18:1/24:0) (OR 2.673; 95% CI 1.225–5.836; P = 0.014) were positively correlated with ACS-DM, and Cer(d18:1/24:0) (OR 0.200; 95% CI 0.051–0.778; P = 0.020) was negatively correlated with ACS-DM. Conclusion Circulating ceramides are positively correlated with the risk of ACS-DM comorbidity. These results give a new insight into the pathogenesis of ACS-DM comorbidity and could provide new options for risk estimation.

Abstract
Cardiovascular disease (CVD) is responsible for 31% of all global deaths. Atherosclerosis is the major cause of cardiovascular disease and is a chronic inflammatory disorder in the arteries. Atherosclerosis is characterized by the accumulation of cholesterol, extracellular matrix, and immune cells in the vascular wall. Recently, the collectin surfactant protein-D (SP-D), an important regulator of the pulmonary immune response, was found to be expressed in the vasculature. Several in vitro studies have examined the role of SP-D in the vascular inflammation leading to atherosclerosis. These studies show that SP-D plays a dual role in the development of atherosclerosis. In general, SP-D shows anti-inflammatory properties, and dampens local inflammation in the vessel, as well as systemic inflammation. However, SP-D can also exert a pro-inflammatory role, as it stimulates C-C chemokine receptor 2 inflammatory blood monocytes to secrete tumor necrosis-factor α and increases secretion of interferon-γ from natural killer cells. In vivo studies examining the role of SP-D in the development of atherosclerosis agree that SP-D plays a proatherogenic role, with SP-D knockout mice having smaller atherosclerotic plaque areas, which might be caused by a decreased systemic inflammation. Clinical studies examining the association between SP-D and cardiovascular disease have reported a positive association between circulatory SP-D level, carotid intima-media thickness, and coronary artery calcification. Other studies have found that circulatory SP-D is correlated with increased risk of both total and cardiovascular disease mortality. Both in vitro, in vivo, and clinical studies examining the relationship between SP-D and CVDs will be discussed in this review.

Abstract
OBJECTIVE Rheumatoid arthritis (RA) patients with the lowest circulating low-density lipoprotein (LDL) concentrations are at heightened risk of cardiovascular events. However, the atherosclerosis burden within this subgroup is unknown. METHODS RA patients pooled from 4 cohort studies of cardiovascular disease (CVD; n = 546) were compared with non-RA controls from the Multi-Ethnic Study of Atherosclerosis (n = 5,279). Those taking lipid-lowering medications were excluded. Differences in cardiac computed tomography-derived Agatston coronary artery calcium (CAC) scores between the RA and control groups were compared across strata of LDL concentration. RESULTS Among those with low LDL concentrations (<70 mg/dl), mean adjusted CAC scores were >4-fold higher for RA patients than for controls (18.6 versus 4.6 Agatston units, respectively; P < 0.001), a difference significantly greater than that in any other LDL concentration stratum except LDL concentration ≥160 mg/dl. Similarly, 32% of the RA patients with low LDL concentration had a CAC score of ≥100 Agatston units compared with only 7% of controls in the same LDL concentration stratum (odds ratio 5.97; P < 0.001), a difference significantly greater than that in all of the other LDL concentration strata. Low LDL concentration was most strongly associated with higher CAC score among RA patients who were white, had ever smoked, or were not obese. Other than a higher frequency of current smokers, RA patients with low LDL concentrations did not have more CVD risk factors or higher measures of RA disease activity or severity than RA patients with higher LDL concentrations. CONCLUSION RA patients with low LDL concentration may represent a group for whom heightened screening and prevention of atherosclerotic CVD is appropriate.

Abstract
The maintenance of physiological levels of nitric oxide (NO) produced by eNOS represents a key element for vascular endothelial homeostasis. On the other hand, NO overproduction, due to the activation of iNOS under different stress conditions, leads to endothelial dysfunction and, in the late stages, to the development of atherosclerosis. Oxidized LDLs (oxLDLs) represent the major candidates to trigger biomolecular processes accompanying endothelial dysfunction and vascular inflammation leading to atherosclerosis, though the pathophysiological mechanism still remains to be elucidated. Here, we summarize recent evidence suggesting that oxLDLs produce significant impairment in the modulation of the eNOS/iNOS machinery, downregulating eNOS via the HMGB1-TLR4-Caveolin-1 pathway. On the other hand, increased oxLDLs lead to sustained activation of the scavenger receptor LOX-1 and, subsequently, to NFkB activation, which, in turn, increases iNOS, leading to EC oxidative stress. Finally, these events are associated with reduced protective autophagic response and accelerated apoptotic EC death, which activates atherosclerotic development. Taken together, this information sheds new light on the pathophysiological mechanisms of oxLDL-related impairment of EC functionality and opens new perspectives in atherothrombosis prevention.

Abstract
Metabolic syndrome (MetS) is a risk factor for type 2 diabetes mellitus and cardiovascular disease. Obesity is a component of the metabolic syndrome. Several genetic variants are reported to be associated with obesity and hypo adiponectinemia, including ars1800796 polymorphism of the interleukin-6 (IL-6) gene. Since obesity is associated with inflammatory factors, the aim of this study was to investigate the association between this polymorphism and MetS and its related features. Obese patients with body mass index (BMI) ≥ 30 (n = 182) were recruited into this study and divided into two groups; 110 patients with MetS, based on the International Diabetes Federation (IDF) criteria, and 72 subjects without MetS. The anthropometric and biochemical data for the groups were compared. Genotyping was carried out using RT-PCR. The association of the genetic polymorphism with MetS and its components were assessed using univariate and multivariate analyzes. There was an association between the presence of the rs1800796polymorphism of the IL-6 gene, with BMI (P = 0.031), high-density lipoprotein (HDL) (P = 0.010) and low-density lipoprotein (LDL) (P = 0.037), while this genetic variant did not show any significant association with the presence of MetS as defined by the IDF. We demonstrate an association between the rs1800796 genetic variant of the IL-6 gene with components of MetS including BMI, and HDL-cholesterol, but not the MetS itself. Therefore, supporting further studies are warranted to investigate this point in a larger population.

Abstract
Altered production of reactive oxygen species (ROS), causing lipid peroxidation and DNA damage, contributes to the progression of atherosclerosis and cancer. Lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) is a lectin-like receptor for oxidized low-density lipoproteins (ox-LDL) primarily expressed in endothelial cells and vasculature-rich organs. LOX-1 receptors is a marker for atherosclerosis, and once activated by ox-LDL or other ligands, stimulates the expression of adhesion molecules, pro-inflammatory signaling pathways and proangiogenic proteins, including NF-kB and VEGF, in vascular endothelial cells and macrophages. Several different types of cancer reported LOX-1 gene upregulation, and numerous interplays exist concerning LOX-1 in atherosclerosis, metabolic diseases and cancer. One of them involves NF-kB, an oncogenic protein that regulates the transcription of several inflammatory genes response. In a model of cellular transformation, the MCF10A ER-Src, inhibition of LOX-1 gene reduces NF-kB activation and the inflammatory and hypoxia pathways, suggesting a mechanistic connection between cellular transformation and atherosclerosis. The remodeling proteins MMP-2 and MMP-9 have been found increased in angiogenesis in atherosclerotic plaque and also in human prostate cancer cells. In this review, we outlined the role of LOX-1 in atherogenesis and tumorigenesis as a potential link in these diseases, suggesting that LOX-1 inhibition could represent a promising strategy in the treatment of atherosclerosis and tumors.

Abstract
For long time, the role of LDL and inflammation in the pathogenesis of atherosclerosis have been studied independently from each other and only more recently a common platform has been suggested. Accumulation of excess cholesterol due to the presence of increased circulating LDL promotes endothelium dysfunction and activation, which is associated with increased production of pro-inflammatory cytokines, overexpression of adhesion molecules, chemokines and C-reactive protein (CRP), increased generation of reactive oxygen species and reduction of nitric oxide levels and bioavailability. All these processes favour the progressive infiltration of inflammatory cells within the arterial wall where cholesterol accumulates, both extracellularly and intracellularly, and promotes vascular inflammation. According to this, lipid-lowering therapies should improve inflammation and, indeed, statins decrease circulating inflammatory markers such as CRP and improve endothelial function and plaque burden. Pleiotropic activities have been proposed to explain this effect. However, mendelian randomization studies ruled out a direct role for CRP on coronary artery disease and studies with other lipid lowering drugs, such as ezetimibe showed that the beneficial effect of LDL-cholesterol-lowering therapies on systemic inflammatory status, as monitored by changes in CRP plasma levels, could be achieved, independently of the mechanism of action, only in patients presenting with baseline inflamed conditions. These observations strengthen the direct link between cholesterol and inflammation and indicate that decreasing LDL levels is one of the key goals for improving cardiovascular outcome.

Abstract
This study focused on an extract from fermented flour from the Lady Joy variety of the common bean Phaseolus vulgaris. The extract, Lady Joy lysate (Lys LJ), is enriched in antioxidant compounds during the fermentation. We assessed it for its protective effect on endothelial cells treated with oxidized-LDL (ox-LDL). The oxidative stress was determined by measuring the contents of thiobarbituric acid-reactive substances and reactive oxygen metabolites. ICAM-1, ET-1 and IL-6 concentrations were assessed using ELISA. LOX-1 and CHOP expression were analyzed using both quantitative RT-PCR and ELISA or western blotting. Ox-LDL treatment induced significant oxidative stress, which was strongly reduced by pre-treatment with the extract. The ox-LDL exposure significantly enhanced ICAM-1, IL-6 and ET-1 levels over basal levels. Lys LJ pre-treatment exerted an inhibitory effect on ox-LDL-induced endothelial activation with ICAM-1 levels comparable to those for the untreated cells. IL-6 and ET-1 production, although reduced, was still significantly higher than for the control. Both LOX-1 and CHOP expression were upregulated after ox-LDL exposure, but this effect was significantly decreased after Lys LJ pre-treatment. Lys LJ alone did not alter the ICAM-1, IL-6 and ET-1 concentrations or CHOP expression, but it did significantly lower the LOX-1 protein level. Our data suggest that Lys LJ is an effective antioxidant that is able to inhibit the oxidation process, but that it is only marginally active against inflammation and ET-1 production in HMEC-1 exposed to ox-LDL.

Abstract
Studies from human and animal models with metabolic disease and hypertension highlight atrophic remodeling, reduced lumen size and thinner vascular walls of microvessels with profound density reduction. This impaired vascular response limits the perfusion of peripheral tissues inducing organ damage. These conditions are strongly associated with oxidative stress and in particular with the up-regulation of lectin-like oxidized low density lipoprotein receptor-1 (LOX-1). Several factors such as cytokines, shear stress, and advanced glycation end-products, especially oxLDL, can up-regulate LOX-1. The activation of this receptor induces the production of adhesion molecules, cytokines and the release of reactive oxygen species via NADPH oxidase. LOX-1 is considered a potent mediator of endothelial dysfunction and it is significantly associated with reduced microvascular endothelium NO-dependent vasodilation in hypercholesterolemia and hypertension. Microvascular endothelial cells increased the expression of IL-6 in association with the increased concentration of LDL and its degree of oxidation. Moreover, increased IL-6 levels are associated with up-regulation of LOX-1 in a dose-dependent manner. Another consequence of microvascular inflammation is the generation of small amounts of ROS, similar to those induced by low concentration of oxLDL (<5 μg/mL) which induces capillary tube formation of endothelial cells, through LOX-1 up-regulation. In light of its central role, LOX-1 represents an attractive therapeutic target for the treatment of human atherosclerotic diseases and microvascular disorders.
