Prognostic value of Toll-like receptor 4 on human monocyte subsets combined with computed tomography-adapted Leaman score assessing coronary artery disease. Coron Artery Dis 2023; 34:356-363. [PMID: 37222220 PMCID: PMC10309091 DOI: 10.1097/mca.0000000000001250] [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: 02/05/2023] [Accepted: 04/21/2023] [Indexed: 05/25/2023]
Abstract
BACKGROUND Upregulation of Toll-like receptor 4 (TLR-4) is associated with coronary plaque vulnerability assessed by coronary computed tomography angiography (CCTA). Computed tomography-adapted Leaman score (CT-LeSc) is an independent long-term predictor of cardiac events. The relationship between the TLR-4 expression of CD14 ++ CD16 + monocytes and future cardiac events is unknown. We investigated this relationship using CT-LeSc in patients with coronary artery disease (CAD). METHODS We analyzed 61 patients with CAD who underwent CCTA. Three monocyte subsets (CD14 ++ CD16 - , CD14 ++ CD16 + , and CD14 + CD16 + ) and the expression of TLR-4 were measured by flow cytometry. We divided the patients into two groups according to the best cutoff value of the TLR-4 expression on CD14 + CD16 + which could predict future cardiac events. RESULTS CT-LeSc was significantly greater in the high TLR-4 group than the low TLR-4 group [9.61 (6.70-13.67) vs. 6.34 (4.27-9.09), P < 0.01]. The expression of TLR-4 on CD14 ++ CD16 + monocytes was significantly correlated with CT-LeSc ( R2 = 0.13, P < 0.01). The expression of TLR-4 on CD14 ++ CD16 + monocytes was significantly higher in patients who had future cardiac events than in those who did not [6.8 (4.5-9.1) % vs. 4.2 (2.4-7.6) %, P = 0.04]. High TLR-4 expression on CD14 ++ CD16 + monocytes was an independent predictor for future cardiac events ( P = 0.01). CONCLUSION An increase in the TLR-4 expression on CD14 ++ CD16 + monocytes is related to the development of future cardiac events.

Predictive Value of Monocyte Chemoattractant Protein-1 in the Development of Diastolic Dysfunction in Patients with Psoriatic Arthritis. DISEASE MARKERS 2022; 2022:4433313. [PMID: 35692875 PMCID: PMC9187441 DOI: 10.1155/2022/4433313] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/26/2022] [Accepted: 05/24/2022] [Indexed: 01/19/2023]
Abstract
We aimed to evaluate the diagnostic accuracy of the proinflammatory monocyte chemotactic protein-1 (MCP-1) in the diagnosis of asymptomatic diastolic dysfunction (DD) in patients with psoriatic arthritis (PsA). The disease activity in psoriatic arthritis (DAPSA) was determined using clinical and laboratory parameters, and echocardiography was performed to estimate DD. Serum MCP-1 concentrations were elevated in PsA patients with DD diagnosed with ultrasound (median (25th percentile, 75th percentile): 366.6 pg/mL (283, 407.1 pg/mL) vs. 277.5 pg/mL (223.5, 319.1 pg/mL) in controls;
). PsA patients with serum MCP-1 concentration higher than the cut-off value of 347.6 pg/mL had a 7.74-fold higher chance of developing DD than PsA patients with lower serum MCP-1 concentrations (controls), with a specificity of 86.36% and sensitivity of 55%, as verified using ultrasound. The group with MCP-1 concentrations above the cut-off value also showed a higher late peak diastolic mitral inflow velocity, A-wave value (
), E/E
ratio (
), and a lower E/A ratio (
), peak systolic left atrial reservoir strain, SA value (
), early peak diastolic displacement of the mitral septal annulus, E
wave value (
), than controls. Systolic blood pressure (
), LDL cholesterol concentration (
), glucose concentration (
), and DAPSA (
) increased in the PsA group with higher MCP-1 concentrations, although there were no differences in comorbidities and therapy between the groups compared. Thus, the serum MCP-1 concentration was a significant and independent prognostic indicator for asymptomatic DD in PsA patients (
,
). The DAPSA score in PsA patients might indicate the need for echocardiography and adjustment of anti-inflammatory treatment in terms of DD prevention.

Abstract
In recent years, intense research has been conducted to explore the diagnostic value of mRNA expression differences in atherosclerosis (AS). Nevertheless, because various technology platforms are applied and sample sizes are small, the results are inconsistent among the studies. We conducted a comprehensive analysis of a total of 161 tissue samples from 4 published studies after evaluating 230 datasets from the Gene Expression Omnibus and ArrayExpress. Adopting the newly published robust rank aggregation approach, combined with Kyoto Encyclopedia of Genes and Genomes pathway analysis, Gene Ontology functional enrichment analysis, and protein-protein interaction network construction, we identified four significantly upregulated genes (CCL4, CCL18, MMP9 and SPP1) for diagnosing AS, even in the advanced stage. Then, we performed gene set enrichment analysis to identify the pathways that were most affected by altered mRNA expression in atherosclerotic plaques. We found that four hub genes cooperatively targeted lipid metabolism and inflammatory immune-related pathways and validated their high expression levels in ruptured plaques by qRT-PCR, western blot analysis and immunohistochemical staining. In summary, our study showed that these genes can be used as interventional targets for plaque progression, and the results suggested we should focus on small changes in these key indicators in the clinical setting.

Abstract
Objective The study was dedicated to investigation of some hemostasis and endothelial dysfunction factors association with probability of presence of vulnerable atherosclerotic plaques in coronary arteries in men with atherosclerosis. Results The blood levels of factor VII, factor XII and MCP-1 were higher, and concentration of sVCAM-1 lower in men with vulnerable atherosclerotic plaques in the coronary arteries, compared to men who had stable plaques. Have been revealed correlation links between the blood levels of factor II, factor XII, MCP-1 and the presence of vulnerable atherosclerotic plaques in the coronary arteries. Results of logistic regression analysis showed that the relative risk of present of vulnerable atherosclerotic plaques in the coronary arteries is associated with an elevated blood level of factor XII and MCP-1.

Abstract
Objective To assess the relationship between serum endostatin (ES) and coronary artery calcification (CAC) in type 2 diabetic (T2DM) patients. Methods The study included 110 participants with coronary artery disease (CAD); 55 with T2DM, for serum ES levels by enzyme-linked immunosorbent assay and CAC by contrast-enhanced spiral computed tomography (CT). Results Mean serum ES value was 66.54 ng/mL [95% confidence interval (CI), 61.77-71.32 ng/mL]. Serum ES levels positively correlated with Agatston score index [ASI; r = 0.701, p < 0.001; high sensitive C-reactive protein (hs-CRP) r = 0.783, p < 0.001]. On multiple regression analysis, the highest three ES quartiles (2, 3, and 4) were related to ASI in diabetic patients, adjusted ES level was an independent predictor of CAD [odds ratio (OR) = 1.065; 95% CI, 1.008-1.126; p = 0.026] and for the number of coronary vessels affected (OR = 1.089; 95% CI, 1.018-1.164; p = 0.013) in T2DM patients. Receiver operating characteristics (ROC) analysis showed serum ES at a cutoff value of 86.5 ng/mL can predict the risk of CAC in T2DM, with a sensitivity of 74.1%, specificity of 71.4%, p < 0.001 and area under curve (AUC) of 0.776. Conclusion Measurement of serum ES levels can improve diagnosis of CAC and could be useful as a high sensitive marker for the presence and progression of atherosclerosis in T2DM patients.

Abstract
Classical risk factors for endothelial dysfunction (ED), such as age, gender, total cholesterol, high-density lipoprotein cholesterol, systolic blood pressure, and smoking history are utilised for the Framingham score and Systemic Coronary Risk Estimation (SCORE) for evaluation of the 10-year cardiovascular risk in routine practice. Nonetheless, pro-inflammatory mediators are deeply involved in the initiation and the progression of ED and coronary artery disease (CAD), and act additionally or independently of metabolic factors before clinical manifestations of the disease appear. C-reactive protein, a marker of intimal thickening of the myeloid-related protein 8/14 heterodimer, monocyte chemotactic protein 1, interleukin-15, the cytotoxic mediator, granulysin, and the matrix metalloproteinase 9 could be valuable, single, fast, and non-invasive laboratory tools for ED deterioration degree assessment. We propose to investigate the impact of pro-inflammatory biomarkers on ED, measured by previously established clinical methods in patients with yet undiagnosed CAD and at medium risk for an acute coronary event. It could be useful to measure and correlate the concentration of particular inflammatory markers in peripheral blood samples and the results of the Framingham and SCORE charts, multi-slice computed tomography coronary angiography, echocardiography, brachial artery flow-mediated dilatation, carotid-femoral pulse wave velocity, ankle-brachial index, carotid wall thickening, myocardial perfusion scintigraphy, and particularly, cardiac magnetic resonance imaging. The goal would be that the degree of correlation between particular inflammatory markers and the results of some methods for the assessment of ED or cardiac ischaemic imaging could be emphasised and pro-inflammatory markers positioned in the pathogenetic algorithm of CAD.

Abstract
BACKGROUND Coronary heart disease (CHD) is characterized by arterial wall inflammation and matrix degradation. Matrix metalloproteinase (MMP)-22 and -29 and pro-inflammatory cytokine interleukin-18 (IL18) are present in human hearts. IL18 may regulate MMP-22 and -29 expression, which may correlate with CHD progression. METHODS AND RESULTS Immunoblot analysis showed that IL18 induced MMP-22 expression in human aortic smooth muscle cells. The Mann Whitney test from a prospective study of 194 CHD patients and 68 non-CHD controls demonstrated higher plasma levels of IL18, MMP-22 and -29 in CHD patients than in the controls. A logistic regression test suggested that plasma IL18 (odds ratio (OR)=1.131, P=0.007), MMP-22 (OR=1.213, P=0.040), and MMP-29 (OR=1.198, P=0.033) were independent risk factors of CHD. Pearson's correlation test showed that IL18 (coefficient (r)=0.214, P=0.045; r=0.246, P=0.031) and MMP-22 (r=0.273, P=0.006; r=0.286, P=0.012) were associated with the Gensini score before and after adjusting for potential confounding factors. The multivariate Pearson's correlation test showed that plasma MMP-22 levels correlated positively with high-sensitive-C-reactive protein (hs-CRP) (r=0.167, P=0.023), and MMP-29 levels correlated negatively with triglyceride (r=-0.169, P=0.018). Spearman's correlation test indicated that plasma IL18 levels associated positively with plasma MMP-22 (r=0.845, P<0.001) and MMP-29 (r=0.548, P<0.001). CONCLUSIONS Our observations suggest that IL18, MMP-22 and -29 serve as biomarkers and independent risk factors of CHD. Increased systemic IL18 in CHD patients may contribute to elevated plasma MMP-22 and -29 levels in these patients.

Abstract
OBJECTIVE Herbal extract compositions are largely used to manage vein diseases. We prepared a new composition of herbs, named FLEBO OK™, that, when administered as a nutraceutical to patients affected by peripheral vascular diseases, was able to improve their health conditions. We analyzed the effects of this nutraceutical composition on in vitro cultured cells with the aim to obtain information about its mechanisms of action. METHODS A culture of human osteoblast cell line Saos-2 was stimulated with tumor necrosis factor (TNF)-α or interleukin (IL)-1β to induce the expression of some chemokines and matrix metalloproteases (MMPs). This cell culture was then exposed to the prepared composition and the amount of expression of the genes coding for the monocyte chemotactic protein (MCP)-1, IL-8, IL-1β, MMP-2, MMP-3, MMP-9 proteins was measured by real-time polymerase chain reaction (RT-PCR). The experiments were repeated exposing the cells to the same amount of the well-known micronized purified flavonoid fraction. Moreover, we describe the effects of the administration of nutraceutical composition to 20 patients affected by peripheral vascular diseases and 20 healthy individuals. RESULTS The RT-PCR analyses showed that the new composition induces the expression of MMP-3 and MMP-9 and downregulates MMP-2 in cell cultures stimulated with IL-1β, whereas it induces the expression of IL-8 and represses the expression of IL-1β and MCP-1 in cell cultures stimulated with TNF-α. The induction of the expression of MMP-3 and the downregulation of MCP-1 might result in an antiplatelet activity that was not observed for the micronized purified flavonoid fraction. Interviewed patients reported an improvement in their conditions after 1 month of FLEBO OK treatment. CONCLUSION These findings could provide a hypothesis for the high efficiency of the identified nutraceutical composition to management of peripheral vascular diseases.

Abstract
AIM To examine the association between the serum endostatin levels and subclinical atherosclerosis independent of traditional risk factors in a healthy Japanese population. METHODS Among 1,057 residents who attended free public physical examinations between 2010 and 2011, we evaluated the data of 648 healthy residents for whom the serum endostatin level and common carotid intima-media thickness (IMT) were successfully measured. RESULTS The median endostatin level was 63.7 ng/mL (interquartile ranges: 49.7-93.2 ng/mL), and the mean carotid IMT was 0.68±0.12 mm. Residents with above median endostatin had significantly higher carotid IMT than did those with below median endostatin (0.71±0.14 vs. 0.65±0.09 mm, P<0.001). Multiple linear regression analysis demonstrated that increased serum endostatin is significantly associated with carotid IMT (above vs. below median endostatin level; beta=0.11, P=0.03), independent of the known covariates of age, sex, body mass index, drinking and smoking status, systolic blood pressure, diastolic blood pressure, hemoglobin A1c, low density lipoprotein cholesterol, estimated glomerular filtration rate, and log-transformed high sensitive C-reactive protein. CONCLUSIONS A higher serum endostatin level reflected subclinical atherosclerosis in this Japanese population.

Abstract
BACKGROUND Although Toll-like receptor 4 (TLR-4) is involved in monocyte activation in patients with accelerated forms of atherosclerosis, the relationship between the expression of TLR-4 on circulating monocytes and coronary plaque vulnerability has not previously been evaluated. We investigated this relationship using 64-slice multidetector computed tomography (MDCT) in patients with stable angina pectoris (SAP).Methods and Results:We enrolled 65 patients with SAP who underwent MDCT. Three monocyte subsets (CD14++CD16-, CD14++CD16+, and CD14+CD16+) and expression of TLR-4 were measured by flow cytometry. Intracoronary plaques were assessed by 64-slice MDCT. We defined vulnerability of intracoronary plaques according to the presence of positive remodeling (remodeling index >1.05) and/or low CT attenuation (<35 HU). The circulating CD14++CD16+monocytes more frequently expressed TLR-4 than CD14++CD16-and CD14+CD16+monocytes (P<0.001). The relative proportion of the expression of TLR-4 on CD14++CD16+monocytes was significantly greater in patients with vulnerable plaque compared with those without (10.4 [4.1-14.5] % vs. 4.5 [2.8-7.8] %, P=0.012). In addition, the relative proportion of TLR-4 expression on CD14++CD16+monocytes positively correlated with the remodeling index (r=0.28, P=0.025) and negatively correlated with CT attenuation value (r=-0.31, P=0.013). CONCLUSIONS Upregulation of TLR-4 on CD14++CD16+monocytes might be associated with coronary plaque vulnerability in patients with SAP.

Abstract
oxLDL peptide vaccine and its antibody adoptive transferring have shown a significantly preventive or therapeutic effect in atherosclerotic animal model. The molecular mechanism behind this is obscure. Here, we report that oxLDL induces MCP‐1 release in monocytes/macrophages through their TLR‐4 (Toll‐like receptor 4) and ERK MAPK pathway and is calcium/potassium channel‐dependent. Using blocking antibodies against CD36, TLR‐4, SR‐AI and LOX‐1, only TLR‐4 antibody was found to have an inhibitory effect and ERK MAPK‐specific inhibitor (PD98059) was found to have a dramatic inhibitory effect compared to inhibitors of other MAPK group members (p38 and JNK MAPKs) on oxLDL‐induced MCP‐1 release. The release of cytokines and chemokines needs influx of extracellular calcium and imbalance of efflux of potassium. Nifedipine, a voltage‐dependent calcium channel (VDCC) inhibitor, and glyburide, an ATP‐regulated potassium channel (K+ATP) inhibitor, inhibit oxLDL‐induced MCP‐1 release. Potassium efflux and influx counterbalance maintains the negative potential of macrophages to open calcium channels, and our results suggest that oxLDL actually induces the closing of potassium influx channel – inward rectifier channel (Kir) and ensuing the opening of calcium channel. ERK MAPK inhibitor PD98059 inhibits oxLDL‐induced Ca2+/Kir channel alterations. The interfering of oxLDL‐induced MCP‐1 release by its monoclonal antibody is through its FcγRIIB (CD32). Using blocking antibodies against FcγRI (CD64), FcγRIIB (CD32) and FcγRIII (CD16), only CD32 blocking antibody was found to reverse the inhibitory effect of oxLDL antibody on oxLDL‐induced MCP‐1 release. Interestingly, oxLDL antibody specifically inhibits oxLDL‐induced ERK MAPK activation and ensuing Ca2+/Kir channel alterations, and MCP‐1 release. Thus, we found a molecular mechanism of oxLDL antibody on inhibition of oxLDL‐induced ERK MAPK pathway and consequent MCP‐1 release.

Abstract
To better understand hypertension development, the authors determined whether monocyte chemoattractant protein-1 (MCP-1) is associated with arterial stiffness (pulse wave velocity [PWV]) and carotid intima-media wall thickness (cIMT) in a young apparently healthy black and white population (N=403, aged 20-30 years). Carotid-femoral PWV, central systolic blood pressure, and cIMT were measured, and MCP-1, reactive oxygen species, inflammatory markers (interleukin 6, tumor necrosis factor α), and endothelial activation (intercellular adhesion molecule, vascular cell adhesion molecule) were determined from blood samples. Although carotid-femoral PWV and cIMT were similar between blacks and whites, black men and women showed higher central systolic blood pressure, MCP-1, and reactive oxygen species than whites (all P<.05). In addition, black women had higher brachial blood pressure and interleukin 6 (all P<.001). A consistent positive association only in black women between cIMT and MCP-1 in multiple regression analyses was found (R²=0.151, β=0.248; P=.021). In this model, cIMT was also independently associated with vascular cell adhesion molecule (β=0.251; P=.022). The authors found elevated central systolic blood pressure and MCP-1 in young blacks, where cIMT was independently associated with MCP-1 in black women.

Abstract
OBJECTIVE Matrix metalloproteinase-9 (MMP-9) plays an important role in the remodeling of the extracellular matrix in atherosclerosis plaques. Autophagy protects macrophages against the processes of vascular disease. Our research explores how autophagy plays roles in macrophages to secret MMP-9. METHODS AND RESULTS In response to increased doses of oxLDL or CQ we monitored the autophagic flux. Our results revealed that oxLDL was dynamically associated with autophagy and 100 μg/ml oxLDL blocked autophagic flux in THP-1 cells. Moreover p62/SQSTM1 knocking down and CQ respectively inhibited and increased MMP-9 transcriptional expression. These effects were mediated by inhibition of NF-κB. CONCLUSION Abundant oxLDL blocked autophagic flux resulting in the aggregation of p62/SQSTM1. Then p62/SQSTM1 was involved in gene expression of MMP-9 via NF-κB-dependent signaling, and thus featuring novel plaque vulnerability properties of the atherosclerotic plaque. Understanding the mechanism that selectively modulates p62/SQSTM1 will provide a novel strategy for anti-atherogenesis.

Abstract
OBJECTIVE Primary hyperparathyroidism (PHPT) has been associated with low-grade inflammation and increased risk of cardiovascular disease (CVD). The aim of the study was to investigate systemic levels of pro-inflammatory proteins that previously have not been examined in patients with PHPT. The selection of the pro-inflammatory biomarkers included in this study, MMP9, S100A4, S100A8/A9 and the receptors sCD14 and RAGE, was based on a previous microarray screen of mRNAs in adipose tissue from PHPT patients. DESIGN A prospective study was conducted on a total of 57 patients with PHPT and a control group of 20 healthy blood donors. METHODS PHPT patients with normalisation of serum calcium levels after parathyroidectomy were followed for 6 months. Forty-two patients participated in the longitudinal study, in which blood samples were taken at inclusion, and 1, 3 and 6 months after surgery. RESULTS We observed increased serum levels of MMP9 (P=0.029), S100A4 (P<0.001) and sCD14 (P=0.002) in the 57 patients with PHPT compared to the control-group. During 6 months of follow up, S100A4 (P=0.022) and sCD14 (0.002) decreased significantly, while serum levels of MMP9 increased (P=0.025). CONCLUSIONS The results demonstrate an increased inflammatory response in PHPT patients shown by elevated MMP9, S100A4 and sCD14 at inclusion. During the 6 months of follow-up, MMP9 increased further, possibly due to the tissue repair process after parathyroidectomy. S100A4 and sCD14 decreased after surgery demonstrating a partial reversal of the systemic inflammation.

Abstract
Background and aims Cystic Fibrosis (CF) lung disease is characterized by progressively declining lung function and represents a major factor contributing to the high morbidity and mortality associated with CF. However, apart from spirometry, respiratory disease surrogate markers reliably indicating CF lung disease and the occurrence of pulmonary exacerbations (PEx) are still lacking. Within this study, we aimed to identify new experimental biomarkers for the detection of CF lung disease. Methods 54 adult and 26 pediatric CF patients were included in the study and serum concentrations of MMP-1, -2, -8, -9, -13, TIMP-1, TIMP-2, YKL-40, hyaluronic acid, procollagen III peptide were quantified by ELISA. CF lung disease was diagnosed by lung function test, PEx was defined based on a clinical scoring established by Rosenfeld in 2001. Results Adults and children with moderate to severe CF lung disease exhibited significantly increased serum expression of MMP-8, MMP-9, YKL-40 and TIMP-1. Further, MMP-8, MMP-9 and YKL-40 were significantly increased in adult CF patients suffering from PEx compared to those without clinical signs of respiratory exacerbation. MMP-8, MMP-9, YKL-40, and TIMP-1 serum levels were unaffected by the presence or absence of CF liver disease or pancreatic insufficiency. Conclusions MMP-8, MMP-9, and YKL-40 might serve as novel non-invasive biomarkers of CF lung disease and PEx.

Abstract
Introduction. Obesity and obstructive sleep apnea syndrome (OSA) are common coexisting conditions associated with a chronic low-grade inflammatory state underlying some of the cognitive, metabolic, and cardiovascular morbidities. Aim. To examine the levels of inflammatory markers in obese community-dwelling children with OSA, as compared to no-OSA, and their association with clinical and polysomnographic (PSG) variables. Methods. In this cross-sectional, prospective multicenter study, healthy obese Spanish children (ages 4–15 years) were randomly selected and underwent nocturnal PSG followed by a morning fasting blood draw. Plasma samples were assayed for multiple inflammatory markers. Results. 204 children were enrolled in the study; 75 had OSA, defined by an obstructive respiratory disturbance index (RDI) of 3 events/hour total sleep time (TST). BMI, gender, and age were similar in OSA and no-OSA children. Monocyte chemoattractant protein-1 (MCP-1) and plasminogen activator inhibitor-1 (PAI-1) levels were significantly higher in OSA children, with interleukin-6 concentrations being higher in moderate-severe OSA (i.e., AHI > 5/hrTST; P < 0.01), while MCP-1 levels were associated with more prolonged nocturnal hypercapnia (P < 0.001). Conclusion. IL-6, MCP-1, and PAI-1 are altered in the context of OSA among community-based obese children further reinforcing the proinflammatory effects of sleep disorders such as OSA. This trial is registered with ClinicalTrials.gov NCT01322763.
