Abstract
OBJECTIVE We assessed the levels of Interleukin-10 (IL-10), Interleukin-12 (IL-12), and Interleukin-18 (IL-18) in the gingival crevicular fluid (GCF) of subjects with advanced periodontitis (SIII-SIV) compared to healthy controls and evaluated their correlations with clinical measurements. METHODS This cross-sectional study involved subjects (n = 60) diagnosed with stage III grade B-C (n = 13) to stage IV grade C (n = 17) periodontitis, and periodontally healthy controls (n = 30). Clinical periodontal measurements involved full-mouth. The concentrations of IL-10, IL-12, and IL-18 were determined using enzyme-linked immunosorbent assay (ELISA). RESULTS There were no significant differences in IL-12 level and IL-18/IL-10 ratio between the healthy and periodontitis groups (p = 0.413, p = 0.636, respectively). The IL-10 and IL-18 levels were significantly higher in the periodontitis group than in controls (p < 0.001, p < 0.001, respectively). Significant associations were observed between the periodontitis and IL-10 and IL-18 levels (OR = 1.46, %95 CI 1.19-1.795; OR = 1.13, %95 CI 1.059-1.207, respectively) (p < 0.001, p < 0.001, respectively). CONCLUSIONS There was a correlation between pocket depth and the presence of IL-18 and a strong association between periodontitis and a high level of IL-18. However, there were no direct correlations among the three biomarkers and IL-18/IL-10 ratio, indicating that their roles in periodontal health are complex and multidimensional. CLINICAL RELEVANCE Understanding the cytokine dynamics in GCF provides valuable insights into their potential clinical implications for periodontal disease diagnosis, risk assessment, and tailored therapeutic interventions.

Abstract
INTRODUCTION Despite significant improvement in secondary CardioVascular (CV) preventive strategies, some acute and chronic coronary syndrome (ACS and CCS) patients will suffer recurrent events (also called "extreme CV risk"). Recently new biochemical markers, such as uric acid (UA), lipoprotein A [Lp(a)] and several markers of inflammation, have been described to be associated with CV events recurrence. The SEcondary preVention and Extreme cardiovascular Risk Evaluation (SEVERE-1) study will accurately characterize extreme CV risk patients enrolled in cardiac rehabilitation (CR) programs. AIM Our aims will be to describe the prevalence of extreme CV risk and its association with newly described biochemical CV risk factors. AIM Our aims will be to describe the prevalence of extreme CV risk and its association with newly described biochemical CV risk factors. METHODS We will prospectively enrol 730 ACS/CCS patients at the beginning of a CR program. Extreme CV risk will be retrospectively defined as the presence of a previous (within 2 years) CV events in the patients' clinical history. UA, Lp(a) and inflammatory markers (interleukin-6 and -18, tumor necrosis factor alpha, C-reactive protein, calprotectin and osteoprotegerin) will be assessed in ACS/CCS patients with extreme CV risk and compared with those without extreme CV risk but also with two control groups: 1180 hypertensives and 765 healthy subjects. The association between these biomarkers and extreme CV risk will be assessed with a multivariable model and two scoring systems will be created for an accurate identification of extreme CV risk patients. The first one will use only clinical variables while the second one will introduce the biochemical markers. Finally, by exome sequencing we will both evaluate polygenic risk score ability to predict recurrent events and perform mendellian randomization analysis on CV biomarkers. CONCLUSIONS Our study proposal was granted by the European Union PNRR M6/C2 call. With this study we will give definitive data on extreme CV risk prevalence rising attention on this condition and leading cardiologist to do a better diagnosis and to carry out a more intensive treatment optimization that will finally leads to a reduction of future ACS recurrence. This will be even more important for cardiologists working in CR that is a very important place for CV risk definition and therapies refinement.

Abstract
BACKGROUND Interleukin-18 (IL-18), a pro-inflammatory cytokine, increases inflammation in the endothelium. Increased inflammation plays an important role in the development of hypertension (HT). IL-18 level is higher in hypertensives than normotensives. OBJECTIVE To investigate the relationship between IL-18 level and diurnal blood pressure (BP) variations in newly diagnosed HT patients. METHODS This prospective study included 130 subjects referred to outpatient cardiology clinic with an initial diagnosis of HT. The patients were classified as dipper HT (n = 40), non-dipper HT (n = 50), and normotensive (control, n = 40) according to 24-hour ambulatory BP monitoring. All subjects underwent blood sampling after 12 hours of fasting and transthoracic echocardiography. RESULTS The serum IL-18 level was significantly higher in the patient group compared with the controls (195.17 ± 93.00 mg/dl vs. 140.75 ± 71.11 mg/dl, P < 0.01) and also in the non-dipper group than in the dipper group (217.3 ± 96.90 mg/dl, 167.5 ± 80.79 mg/dl, P = 0.011). IL-18 level was positively correlated both the night-time SBP and DBP levels (r = 0.29, P = 0.02 and r = 0.34, P < 0.01, respectively). On multivariate linear regression analysis, left atrium diameter, left ventricular mass index, and serum IL-18 level were independent predictors of non-dipping pattern in newly diagnosed HT patients. CONCLUSION Higher IL-18 level was particularly associated with an increase in the night-time BP levels. IL-18 can be used as a predictor for non-dipper HT in newly diagnosed HT patients.

Abstract
Background: Diabetes is a long-term condition that can be treated and controlled but do not yet have a cure; it could be induced by inflammation and the goal of managing it is to prevent additional co-morbidities and reduce glycemic fluctuations. There is a need to examine inflammatory activities in diabetes-related angiopathies and explore interventions that could reduce the risk for future outcome or ameliorate its effects to provide insights for improved care and management strategies. Method: The study was conducted in Embase (1946–2020), Ovid Medline (1950–2020), and PubMed databases (1960–2020) using the PICO framework. Primary studies (randomized controlled trials) on type 2 diabetes mellitus and inflammatory activities in diabetes-related angiopathies were included. Terms for the review were retrieved from the Cochrane library and from PROSPERO using its MeSH thesaurus qualifiers. Nine articles out of 454 total hits met the eligibility criteria. The quality assessment for the selected study was done using the Center for Evidence-Based Medicine Critical Appraisal Sheet. Results: Data analysis showed that elevated CRP, TNF-α, and IL-6 were the most commonly found inflammatory indicator in diabetes-related angiopathies, while increased IL-10 and soluble RAGE was an indicator for better outcome. Use of drugs such as salsalate, pioglitazone, simvastatin, and fenofibrate but not glimepiride or benfotiamine reported a significant decrease in inflammatory events. Regular exercise and consumption of dietary supplements such as ginger, hesperidin which have anti-inflammatory properties, and those containing prebiotic fibers (e.g., raspberries) revealed a consistent significant (p < 0.05) reduction in inflammatory activities. Conclusion: Inflammatory activities are implicated in diabetes-related angiopathies; regular exercise, the intake of healthy dietary supplements, and medications with anti-inflammatory properties could result in improved protective risk outcome for diabetes patients by suppressing inflammatory activities and elevating anti-inflammatory events.

Abstract
BACKGROUND Over the last decades, the role of inflammation and immune system activation in the initiation and progression of coronary artery disease (CAD) has been established. OBJECTIVES The study aimed to present the interplay between cytokines and their actions preceding and shortly after ACS. METHODS We searched in a systemic manner the most relevant articles to the topic of inflammation, cytokines, vulnerable plaque and myocardial infarction in MEDLINE, COCHRANE and EMBASE databases. RESULTS Different classes of cytokines (intereleukin [IL]-1 family, Tumor necrosis factor-alpha (TNF-α) family, chemokines, adipokines, interferons) are implicated in the entire process leading to destabilization of the atherosclerotic plaque, and consequently, to the incidence of myocardial infarction. Especially IL-1 and TNF-α family are involved in inflammatory cell accumulation, vulnerable plaque formation, platelet aggregation, cardiomyocyte apoptosis and adverse remodeling following the myocardial infarction. Several cytokines such as IL-6, adiponectin, interferon-γ, appear with significant prognostic value in ACS patients. Thus, research interest focuses on the modulation of inflammation in ACS to improve clinical outcomes. CONCLUSION Understanding the unique characteristics that accompany each cytokine-cytokine receptor interaction could illuminate the signaling pathways involved in plaque destabilization and indicate future treatment strategies to improve cardiovascular prognosis in ACS patients.

Abstract
We examined the precise association between IL-10 levels and cardiovascular disease (CVD) prognosis and explored the pleiotropic role of IL-10 in different cardiac pathologies. We performed a meta-analysis of cross-sectional and longitudinal studies investigating IL-10 levels. Meta-regression analyses were used to determine the cause of the discrepancies. To assess publication bias, funnel plots were constructed, and Egger's tests were performed. Data from the GSE58015 dataset were used to investigate the levels of IL-10 under certain conditions. Because of substantial heterogeneity in the data used to compare the IL-10 levels between patients with CVD and healthy people, we could not determine the differences between the healthy controls and patients with ischemic or nonischemic pathologies (p > 0.05). The analysis of the association between IL-10 levels and CVD prognosis indicated that higher IL-10 levels were significantly associated with a poor prognosis in patients with nonischemic pathologies (HR = 1.10, 95% CI = 1.00-1.20, p = 0.043) but differentially associated with the prognosis of patients with ischemic pathologies based on the sampling time point (before percutaneous coronary intervention (PCI): HR = 4.90, 95% CI = 1.24-19.30, p < 0.001; after PCI: HR = 0.57, 95% CI = 0.43-0.75, p = 0.023). The meta-regression analysis showed that the pooled HR of the IL-10 levels was positively correlated with the IL-10/IL-6 ratio (β = 0.644, p = 0.024). The funnel plots and Egger's tests revealed no statistically significant bias in our meta-analysis (p > 0.1). Furthermore, our data mining analysis supported our findings. Our analysis showed that IL-10 levels may be pleiotropically associated with the CVD prognosis possibly based on the type of pathology, disease stage and levels of other proinflammatory factors, such as IL-6.

Abstract
Interleukin-37 (IL-37) is unique in the IL-1 family since it broadly suppresses innate immunity and elevates in humans with inflammatory and autoimmune diseases. IL-37 shows definite groups and transcripts for human IL37 gene, but it is still not completely understood the effect and mechanisms of inflammatory response in endothelial cells. It is well accepted that endothelial dysfunction caused by inflammation is a key initiating event in atherosclerotic plaque formation, which leads to the occurrence and development of the cardiovascular adverse events in clinical since the inflammatory responses of endothelial cells could induce and enhance the deposition of extensive lipid and the formation of atherosclerotic plaque in the intima. Thus, it is essential to investigate the role and potential mechanisms in endothelial inflammatory response to prevent the formation and development of many cardiovascular diseases including atherosclerosis. So far, the recent studies have revealed that IL-37 is able to inhibit inflammatory response by suppressing the TLR2-NF-κB-ICAM-1 pathway intracellularly in human coronary artery endothelial cells (HCAECs). Further, the role of IL-37 may be related to the IL-18 pathway extracellularly and involved in the adhesion and transmigration of neutrophils in HCAECs.

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 To examine the evidence for shared pathophysiological pathways in acute coronary syndrome and major depression and to conceptualise the dynamic interplay of biological systems and signalling pathways that link acute coronary syndrome and depression within a framework of neuro-visceral integration. METHODS Relevant articles were sourced via a search of published literature from MEDLINE, EMBASE and PubMed using a variety of search terms relating to biological connections between acute coronary syndrome and depression. Additional articles from bibliographies of retrieved papers were assessed and included where relevant. RESULTS Despite considerable research efforts, a clear understanding of the biological processes connecting acute coronary syndrome and depression has not been achieved. Shared abnormalities are evident across the immune, platelet/endothelial and autonomic/stress-response systems. From the available evidence, it seems unlikely that a single explanatory model could account for the complex interactions of biological pathways driving the pathophysiology of these disorders and their comorbidity. CONCLUSION A broader conceptual framework of mind-body or neuro-visceral integration that can incorporate the existence of several causative scenarios may be more useful in directing future research and treatment approaches for acute coronary syndrome-associated depression.

Abstract
Objective To investigate the relationship between plasma fetuin-A, an anti-inflammatory glycoprotein which might be involved in myocardial healing after acute infarction, and infarct size, left ventricular (LV) function and dimensions as well as the occurrence of adverse remodelling at 4 months after acute ST segment elevation myocardial infarction (STEMI). Methods In this single-centre prospective, observational study, 89 patients underwent cardiac MR within the first week and 4 months after mechanical reperfusion for first STEMI. Infarct size, LV function and dimensions were assessed at both time points. Fetuin-A levels were determined from blood samples drawn at a median of 49 h (IQR 30–59 h) after STEMI by an immunofluorescent assay. Results Fetuin-A levels (median 568 µg/mL, IQR 478–763 µg/mL) were significantly correlated with infarct size and LV ejection fraction at baseline and follow-up (all p<0.05). Moreover, fetuin-A was related to the increase in the end-diastolic volume index (r=−0.383, p<0.001). According to multivariate logistic regression analysis, fetuin-A concentrations (HR=0.17, 95% CI 0.03 to 0.89, p=0.036) besides the presence of late microvascular obstruction (HR=10.03, 95% CI 0.98 to 102.43, p=0.05) were significantly related to the occurrence of adverse LV remodelling at 4 months. Conclusions Circulating fetuin-A at day 2 after STEMI is related to acute and chronic infarct size, LV function and dimensions. In addition, it might be useful to identify patients at increased risk for adverse LV remodelling.

Abstract
OBJECTIVE Acute ST-segment elevation myocardial infarction (ASTEMI) is accompanied by increased expression of inflammation and decreased expression of anti-inflammation. IL-37 was found to be involved in the atherosclerosis-related diseases and increased in acute coronary syndrome. However, the level of IL-37 in blood plasma and leukocytes from patients with ASTEMI after percutaneous coronary intervention (PCI) has not been explored. METHODS We collected peripheral venous blood from consented patients at 12 h, 24 h, and 48 h after PCI and healthy volunteers. Plasma IL-37, IL-18, IL-18-binding protein (BP), and high sensitive C reaction protein (hs-CRP) were quantified by ELISA and leukocytic IL-37 and ICAM-1 by immunoblotting. RESULTS Plasma IL-37, IL-18, and IL-18 BP expression decreased compared to those in healthy volunteers while hs-CRP level was high. Both leukocytic IL-37 and ICAM-1 were highest expressed at 12 h point but significantly decreased at 48 h point. CONCLUSION These findings suggest L-37 does not play an important role in the systematic inflammatory response but may be involved in leukocytic inflammation in ASTEMI after PCI.

Systemic toll-like receptor and interleukin-18 pathway activation in patients with acute ST elevation myocardial infarction. J Mol Cell Cardiol 2014; 67:94-102.

Abstract
Acute myocardial infarction (AMI) is accompanied by increased expression of Toll like receptors (TLR)-2 and TLR4 on circulating monocytes. In animal models, blocking TLR2/4 signaling reduces inflammatory cell influx and infarct size. The clinical consequences of TLR activation during AMI in humans are unknown, including its role in long-term cardiac functional outcome Therefore, we analyzed gene expression in whole blood samples from 28 patients with an acute ST elevation myocardial infarction (STEMI), enrolled in the EXenatide trial for AMI patients (EXAMI), both at admission and after 4-month follow-up, by whole genome expression profiling and real-time PCR. Cardiac function was determined by cardiac magnetic resonance (CMR) imaging at baseline and after 4-month follow-up. TLR pathway activation was shown by increased expression of TLR4 and its downstream genes, including IL-18R1, IL-18R2, IL-8, MMP9, HIF1A, and NFKBIA. In contrast, expression of the classical TLR-induced genes, TNF, was reduced. Bioinformatics analysis and in vitro experiments explained this noncanonical TLR response by identification of a pivotal role for HIF-1α. The extent of TLR activation and IL-18R1/2 expression in circulating cells preceded massive troponin-T release and correlated with the CMR-measured ischemic area (R=0.48, p=0.01). In conclusion, we identified a novel HIF-1-dependent noncanonical TLR activation pathway in circulating leukocytes leading to enhanced IL-18R expression which correlated with the magnitude of the ischemic area. This knowledge may contribute to our mechanistic understanding of the involvement of the innate immune system during STEMI and may yield diagnostic and prognostic value for patients with myocardial infarction.

Abstract
OBJECTIVE Interleukin (IL)-18 has been associated with severity of atherosclerosis and discussed to predict cardiovascular (CV) events. We have previously shown that the IL-18+183 G-allele significantly reduces IL-18 levels. This study was aimed to investigate the prognostic significance of the IL-18+183 A/G polymorphism (rs5744292), single and in coexistence with the matrix metalloproteinase (MMP)-9 -1562 C/T (rs3918242) polymorphism, in patients with stable coronary artery disease (CAD). Serum levels of IL-18, MMP-9 and tissue inhibitor of matrix metalloproteinase (TIMP)-1 were additionally assessed. METHODS 1001 patients with angiographically verified CAD were genotyped and the biomarkers were measured accordingly. After two years follow-up, 10.6% experienced new clinical events; acute myocardial infarction (AMI), stroke, unstable angina pectoris and death. RESULTS The IL-18+183 G-allele associated with 35% risk reduction in composite endpoints after adjusting for potential covariates (p = 0.044). The IL-18+183 AA/MMP-9 -1562 CT/TT combined genotypes associated with a significant increase in risk of composite endpoints (OR = 1.87; 95% CI = 1.13-3.11, p = 0.015, adjusted). Patients with clinical events presented with significantly higher IL-18 levels as compared to patients without (p = 0.011, adjusted). The upper tertile of IL-18 levels associated with an increase in risk of AMI as compared to lower tertiles (OR = 2.36; 95% CI = 1.20-4.64, p = 0.013, adjusted). CONCLUSION The IL-18+183 A/G polymorphism, single and in combination with MMP-9 genotypes, may influence the risk of clinical events in stable CAD patients.

Abstract
Fetuin-A is a ubiquitous anti-inflammatory glycoprotein that counteracts proinflammatory cytokine production. Previous studies have shown that low fetuin-A concentration is associated with cardiovascular death and may play an important role in the prognosis of patients with acute coronary syndromes (ACS). The purpose of this study was to assess in large cohort of patients admitted for ACS the prognostic value of fetuin-A adjusted for C-reactive protein value (CRP) and Global Registry of Acute Coronary Events (GRACE) risk score. Plasma fetuin-A and CRP concentrations were measured on day 3 in 754 consecutive patients with ACS (mean age 66 ± 14 years, 404 with ST-segment elevation and 350 without ST-segment elevation) included in the French Registry of Acute ST-Elevation or Non-ST-Elevation Myocardial Infarction (FAST-MI), and these data were correlated to 1-year mortality. Plasma fetuin-A and CRP concentrations at admission averaged 95 ± 27 and 12 ± 16 mg/L, respectively. Overall, 1-year cardiovascular mortality was 10% (28 in-hospital deaths and 51 deaths after discharge), 17% in patients with low fetuin-A (less than the first tertile), 18% with high CRP (higher than the third tertile), and 23% in patients with low fetuin associated with high CRP (p <0.01). In contrast, patients with neither low fetuin-A nor high CRP had a low mortality rate (5%). Multivariate analysis adjusted for GRACE risk score showed that low fetuin-A and high CRP concentration remained associated with outcomes (odds ratio 2.28, 95% confidence interval 1.20 to 4.33). In conclusion, fetuin-A combined with CRP level is associated with cardiovascular death in patients with ACS.

Abstract
OBJECTIVE In the present study, the efficacy of Naoxintong capsule (NXT), a compound Chinese herbal medicine, combined with dual antiplatelet therapy (DA) in a rat model of coronary microembolization (CME) was evaluated. METHODS CME in rats was developed by injecting a suspension of microthrombotic particles into the left ventricle when the ascending aorta was obstructed. Microthrombotic particles were generated from the clots of rats sized by filtration through a screen (aperture diameter, 38 μm). A total of 95 rats were randomly divided into six groups, including control group, sham-operation (sham) group, CME model (CME) group, and NXT, DA, and NDA (NXT plus DA) groups. Rats in treatment groups were administered intragastrically with NXT, DA, and NDA, respectively, from 3 d before to 7 d after operation. All rats were sacrificed on day 7 post-operationally, and samples of blood and heart were collected. The complete data of 69 rats were obtained. The incidence of CME (CME%) was evaluated by hematoxylin-eosin staining. Bleeding time (BT) and clotting time (CT) were measured by means of tail cutting and glass slide methods, respectively. Adenosine diphosphate-induced maximum platelet aggregation rate (PAR) was assessed with turbidimetry. Platelet counts were examined by an automated hematology analyzer. The levels of serum P-selectin, interleukin (IL)-6, IL-10, endothelin (ET-1) and endothelial nitric oxide synthase (eNOS) were all detected by enzyme-linked immunosorbent assay. RESULTS Compared with control and sham groups, CME group had an increase in CME%, PAR, P-selectin, IL-6 and ET-1 (P<0.01, P<0.01), and a decrease in BT, CT, IL-10 and eNOS (P<0.01, P<0.01); compared with CME group, the groups receiving medications had an increase in BT, CT, IL-10 and eNOS (P<0.05 or P<0.01), and a decrease in CME%, PAR, P-selectin, IL-6 and ET-1 (P<0.05 or P<0.01), with DA group increasing most in BT and CT and decreasing most in PAR and P-selectin, and with NDA group increasing most in IL-10 and eNOS and decreasing most in CME%, IL-6 and ET-1. In terms of platelet counts, there was no statistically significant difference among groups (P>0.05). CONCLUSION NXT combined with DA can decrease CME%. The probable mechanism is that this therapy can appropriately inhibit platelet aggregation, balance the pro- and anti-inflammatory cytokines as well as serum ET-1 and eNOS. This therapy can also reduce risk of intraoperative bleeding during DA therapy.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disease with heterogeneous manifestations including severe organ damage and vascular dysfunction leading to premature atherosclerosis. IFN-α has been proposed to have an important role in the development of lupus and lupus-related cardiovascular disease, partly by repression of IL-1 pathways leading to impairments in vascular repair induced by endothelial progenitor cells (EPCs) and circulating angiogenic cells (CACs). Counterintuitively, SLE patients also display transcriptional upregulation of the IL-1β/IL-18 processing machinery, the inflammasome. To understand this dichotomy and its impact on SLE-related cardiovascular disease, we examined cultures of human and murine control or lupus EPC/CACs to determine the role of the inflammasome in endothelial differentiation. We show that caspase-1 inhibition improves dysfunctional SLE EPC/CAC differentiation into mature endothelial cells and blocks IFN-α-mediated repression of this differentiation, implicating inflammasome activation as a crucial downstream pathway leading to aberrant vasculogenesis. Furthermore, serum IL-18 levels are elevated in SLE and correlate with EPC/CAC dysfunction. Exogenous IL-18 inhibits endothelial differentiation in control EPC/CACs and neutralization of IL-18 in SLE EPC/CAC cultures restores their capacity to differentiate into mature endothelial cells, supporting a deleterious effect of IL-18 on vascular repair in vivo. Upregulation of the inflammasome machinery was operational in vivo, as evidenced by gene array analysis of lupus nephritis biopsies. Thus, the effects of IFN-α are complex and contribute to an elevated risk of cardiovascular disease by suppression of IL-1β pathways and by upregulation of the inflammasome machinery and potentiation of IL-18 activation.

Abstract
BACKGROUND Thrombin has a role not only in the coagulation process but also in inflammatory responses. Oral direct thrombin inhibitors (DTIs) are currently being evaluated in patients with thromboembolic diseases. OBJECTIVE To investigate whether an oral DTI affects markers for platelet and inflammatory activity after myocardial infarction (MI). METHODS A total of 518 patients with MI were randomly assigned to ximelagatran treatment (four different dose groups) in combination with aspirin, or aspirin alone for 6 months. The levels of soluble (s) P-selectin, soluble tissue factor, C-reactive protein (CRP), interleukin (IL)-10 and IL-18 were analysed in serial blood samples. RESULTS sP-selectin concentration increased after 1 week and persisted at an elevated level for 6 months in all study groups (P < 0.001). In the two highest ximelagatran dose groups, there was a reduced increase in sP-selectin compared to treatment with lower doses of ximelagatran and aspirin alone (P = 0.01 and P = 0.002, respectively). IL-18 levels did not change in the aspirin alone treatment group. By contrast, there was an elevation in IL-18 level in the lower and higher ximelagatran dose groups after 6 months (P = 0.006 and P < 0.001, respectively). Ximelagatran increased IL-10 levels (P = 0.002) and reduced the decrease in CRP levels after 6 months compared to treatment with aspirin alone (P = 0.002). CONCLUSION A persistent elevation of platelet activity is found in patients with a recent MI after the cessation of acute antithrombotic treatment, and the addition of an oral DTI at higher doses decreases the activity. By contrast, long-term treatment with a DTI increases the levels of several markers of inflammation. Further studies with prolonged exposure of oral DTIs are needed for evaluation of the effect on inflammatory processes and to determine whether these agents influence clinical outcomes.

Elevated plasma asymmetric dimethylarginine level in acute myocardial infarction patients as a predictor of poor prognosis and angiographic impaired reperfusion. Atherosclerosis 2011; 219:304-10. [PMID: 21726864 DOI: 10.1016/j.atherosclerosis.2011.06.021] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2011] [Revised: 06/12/2011] [Accepted: 06/12/2011] [Indexed: 11/22/2022]
Abstract
OBJECTIVES We aimed to investigate the effects of admission asymmetric dimethylarginine (ADMA) levels on myocardial perfusion and prognosis in ST-segment elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PCI). BACKGROUND ADMA, an endogenous inhibitor of endothelial nitric oxide synthase, was found to be elevated in plasma of patients with cardiovascular risk factors. METHODS 168 consecutive patients undergoing primary PCI for STEMI <12 h after symptom onset and 75 healthy age and sex matched volunteer controls were enrolled in the study. Patients with STEMI were grouped into tertiles according to their admission plasma ADMA levels. Major adverse cardiac events during hospitalization or at one-year clinical follow-up were evaluated. Also angiographic impaired reperfusion was assessed by 3 different methods after PCI: angiographic thrombolysis in myocardial infarction (TIMI) flow, TIMI frame count and TIMI myocardial perfusion grade (TMPG). RESULTS Plasma level of L-arginine were lower in patients with STEMI than in the control group subjects, whereas plasma ADMA levels were increased in the STEMI patient group. The rate of impaired angiographic reperfusion increased across the tertile groups. Also one-year mortality rates showed a significant increase across the tertile groups (4% vs. 10% vs. 20%, p<0.01). Using multiple Cox regression analysis, only TIMI risk score, left ventricle ejection fraction (LVEF), abnormal TMPG, and increased ADMA values on admission emerged as independent predictors of one-year mortality. The ROC analysis indicated an optimal cut-point of ≥1.37 μmol/L, which detects one-year mortality with a negative predictive value of 96%. CONCLUSIONS In STEMI patients undergoing primary PCI, high admission ADMA levels were found to be associated with impaired myocardial perfusion and increased one-year mortality. Therefore admission ADMA level detection may be helpful in identifying the patients at a greater risk of impaired myocardial perfusion and poor prognosis.

Abstract
AIM The aim of this study is to investigate the T helper (Th)2-dependent release of interleukin(IL)-4 and IL-13 in patients with unstable angina treated with coronary angioplasty (PCI). METHODS This study involved 48 consecutive patients with unstable angina who underwent PCI. Blood samples were taken before and 48 h after PCI to evaluate serum IL-4 and IL-13 levels. Coronary atherosclerosis was assessed in terms of the severity of the treated lesions and the presence of multivessel disease, and compared with IL release. RESULTS Before and after PCI, serum IL-4 levels were, respectively, 53.1+/-110.7 and 35.1+/-16.9 pg/ml (P not significant), and serum IL-13 levels 6.7+/-3.7 and 6.0+/-2.9 pg/ml (P<0.05). A correlation was present between the severity of the treated coronary lesions and serum IL-13 levels (r 0.36; P<0.05). The patients with multivessel coronary artery disease had a higher periprocedure ratio of IL-4 than those with single-vessel coronary artery disease (1.46+/-0.76 vs. 0.89+/-0.34, P<0.001). CONCLUSION A significant decrease was observed in Th2-dependent IL concentrations after PCI; increased Th2-dependent IL levels before PCI seem to correlate with the severity of coronary atherosclerosis.

Abstract
Initiation and progression of coronary atherosclerosis has been associated with inflammation and cytokines balance. The objective of this study is to understand the role of cytokines in the pathophysiology and management of coronary artery disease. Coronary artery disease has been revisited with revision of the pertinent published articles in the Medline, Scopus, and EBSCO Host research from 1987 to 2007. The 2 groups of cytokines (proinflammatory and anti-inflammatory) have been detected in human atherosclerotic plaques. The balance between the 2 groups may reflect the intensity of occult plaque inflammation and the vulnerability to rupture. Multiple studies have determined that a diverse set of proinflammatory biomarkers can furnish prognostic information beyond the traditional risk factors. Inflammatory responses after coronary revascularization are known to play key role in vascular lesion formation early in atherosclerosis and restenosis. Clinical utilization of cytokines remains promising yet incompletely explored and need more studies.

Abstract
BACKGROUND Diabetes mellitus (DM) and chronic inflammation are strongly related to increased cardiovascular risk. The purpose of this study was to evaluate whether an aerobic training programme would ameliorate inflammatory and anti-inflammatory markers in patients with type 2 DM. DESIGN Interventional study. METHODS A total of 60 overweight individuals with type 2 DM, but without vascular complications, were randomly assigned to either a 6-month aerobic exercise training programme (four times/week, 45-60 min/session), designated as exercise group, or to the control group. All participants were on an oral antidiabetic regimen and none was receiving lipid-lowering medications. Anthropometric parameters, cardiorespiratory fitness, glycaemic and lipid profiles, high sensitivity C-reactive protein (hs CRP), adiponectin, interleukin (IL)-10, IL-18, tumour necrosis factor (TNF)-alpha, insulin, reciprocal index of homoeostasis model assessment (HOMA-IR), body fat and blood pressure (BP) were measured at baseline and at the end of the study. RESULTS In comparison with baseline and control group, exercise-treated patients improved glucose control, lipid profile, exercise capacity (VO2 peak) and exhibited decreased insulin resistance and systolic BP considerably (P<0.05). Plasma adiponectin, TNF-alpha and body weight changed slightly across treatment (P>0.05), whereas diastolic BP and fat mass tended to decrease (P=0.071 and 0.061, respectively). Exercise training reduced hs CRP (from 0.48+/-0.16 to 0.29+/-0.2 mg/dl; P=0.04) and IL-18 (from 315.19+/-122.76 to 203.77+/-96.02 pg/ml; P=0.02). Moreover, exercise provided anti-inflammatory protection through IL-10 increment (P=0.039) and IL-18/IL-10 ratio downregulation (P=0.014). In multiple regression analysis, alteration in IL-18 was independently correlated with hs CRP and VO2 peak changes (P<0.05). CONCLUSION Aerobic exercise training without significant weight loss improves metabolic profile and exerts anti-inflammatory effects in patients with type 2 DM.

Abstract
OBJECTIVE To investigate free interleukin-18 (fIL-18) levels, and variation within the IL-18 system genes, in heart surgery patients, and healthy men. METHODS AND RESULTS fIL-18 was calculated from IL-18 and IL-18 binding protein (BP) levels, in 421 healthy men and 196 post-coronary artery bypass graft (CABG) patients. After surgery, fIL-18 peaked at 6 hours (from 117 to 331 pg/mL) but fell to below presurgery levels at 24 hours (99 pg/mL), because of changes in total IL-18 and IL-18BP. fIL-18 24 hours postsurgery was significantly higher in those who suffered a major complication after surgery (125 versus 80 pg/mL, P<0.01). Baseline total IL-18 was also higher in healthy men who went on to suffer an MI over 17 years of prospective study (276 versus 240 pg/mL, P=0.01). Tagging SNPs for IL18 (n=5) and IL18BP (n=3) were determined, in both studies the IL18 HapIII haplotype (frequency 30%) was associated with 36% lower baseline fIL-18 levels before surgery (P<0.01), and 7% lower in healthy men (P=0.04). The frequency of HapIII was lower in CABG patients than in healthy men (20.7 versus 29.8%, P<0.01). CONCLUSIONS IL-18 levels, which are determined in part by variation in IL18, play a role in CHD development and postsurgery outcome.

Abstract
Abstract
Background: Fetuin-A inhibits inflammation and has a protective effect against myocardial ischemia. Its deficiency has been found to be associated with cardiovascular death in patients with end-stage renal failure disease. We investigated the association between plasma fetuin-A and clinical outcome after ST-elevation acute myocardial infarction (STEMI).
Methods: We measured fetuin-A in 284 consecutive patients with STEMI and correlated these data with the occurrence of death at 6 months (n = 25). We also measured fetuin-A in a control group and chose the 95th percentile as the cutoff to define abnormality.
Results: Patient mean (SD) age was 60 (14) years, and creatinine clearance was 83 (31) mL/min; 82% were men. Mean (SD) plasma fetuin-A concentrations at admission [188 (69) mg/L, P = 0.01] and at day 3 [163 (57) mg/L, P <0.0001] were lower in patients than in controls [219 (39) mg/L; 95th percentile 140 mg/L]. Fetuin-A <140 mg/L was observed in 20% of patients at admission vs 40% at day 3 (P <0.001). Fetuin-A concentrations did not correlate with peak cardiac troponin values but did correlate inversely with C-reactive protein (CRP) and NT-pro-brain natriuretic peptide (NT-proBNP). Fetuin-A <140 mg/L at admission (OR = 3.3, P = 0.03) and at day 3 (OR = 6.3, P = 0.002) was an independent correlate of death at 6 months, irrespective of NT-proBNP, CRP, or Controlled Abciximab and Device Investigation to Lower Late Angioplasty Complications (CADILLAC) risk score. Conversely, fetuin-A ≥140 mg/L was associated with an excellent survival rate [negative predictive value (NPV) = 97% overall], even in high-risk populations with CADILLAC risk score ≥6 (NPV = 90% in patients).
Conclusions: Fetuin-A is an important predictor of death at 6 months in STEMI patients independent of NT-proBNP, CRP, and CADILLAC risk score.

Abstract
AIM To investigate release of some inflammatory cytokines (Cys) after coronary angioplasty and its links with coronary atherosclerosis. METHODS Twenty-seven consecutive subjects with acute coronary syndrome (ACS) who underwent percutaneous coronary intervention (PCI) were enrolled in the study: serial blood samples were taken in order to evaluate plasma concentrations of Interleukin (IL)-2, IL-10, IL-18, TNFalpha, and IFNgamma just before PCI at 12 and 24 hours. Patients were then divided, considering balance between each inflammatory Cy and IL-10, an antiinflammatory Cy, into four groups, ranging from a prevalent antiinflammatory response (stable inflammatory Cy-increasing IL-10 values) to a marked inflammatory imbalance (increasing inflammatory Cy-stable IL-10 values). RESULTS All Cys showed significant increases in plasma concentrations if compared with baseline values. Release curves were not significantly different when comparing subjects with ST-elevation myocardial infarction (STEMI) versus unstable angina-non-STEMI (UA-NSTEMI), diabetics versus controls. Subjects with marked inflammatory response showed a higher incidence of stenosis on left anterior descending (LAD) coronary artery (IL-2 chi(2) and IFNgamma P < 0.05); Cy release was higher in patients with multivessel coronary disease (IL-2 and IFNgamma, ANOVA P < 0.01). Correlations were also referable between Cys and myocardial enzyme release. Subjects treated with sirolimus-eluting stents (SES) showed significantly lower Cy periprocedure ratio if compared with those treated with bare metal stents. CONCLUSIONS A significant Cy release is detectable after PCI: inflammatory response seems to correlate with both PCI due to plaque instabilization and coronary atherosclerosis. A blunted inflammatory response is detectable in subjects treated with SES.

Abstract
BACKGROUND Numerous inflammatory mediators such as C-reactive protein (CRP), fibrinogen, interleukin-18 (IL-18), and inter-cellular adhesion molecule-1 (ICAM-1) have been proposed for risk stratification in acute coronary syndrome (ACS) patients. However, interactions between these markers have made it difficult to assess their true role in risk prediction. Factor analysis is a multivariable statistical technique that reduces a large number of intercorrelated variables to a smaller set of independent clusters, underlining physiological relationships. The aim of this study was to investigate, using factor analysis, a clustering of pro-inflammatory markers, anti-inflammatory cytokines such as interleukin-10 (IL-10) and HDL cholesterol, and to determine their role in prediction of risk of recurrent coronary events in ACS patients. METHODS We assessed 320 consecutive patients (236 men; 67 years; IQ 58-74 years) admitted with ACS. The composite of cardiac death and re-hospitalization with non-fatal myocardial infarction, or unstable angina, was the pre-specified study end-point. Serum CRP, fibrinogen, HDL cholesterol, IL-10, IL-18 and ICAM-1 levels were measured at study entry. We assessed independent predictors of the combined end-point during a 1-year follow-up using multiple logistic regression analysis. RESULTS Factor analysis identified three clusters which were arbitrarily interpreted as (1) a "systemic inflammation" cluster with positive loadings of CRP and fibrinogen, (2) a "local inflammation-endothelial dysfunction" cluster with positive loadings of IL-18 and ICAM-1 and (3) an "anti-inflammation" cluster comprising IL-10 and HDL cholesterol. Only the "anti-inflammation" cluster was a significant predictor (OR 0.66, 95% CI: 0.49-0.89) of adverse cardiac events during a 1-year follow-up and remained significant (OR 0.65, 95% CI: 0.48-0.88) in a multivariate model that included all three factors. CONCLUSIONS Although inflammatory markers such as CRP predict future cardiovascular events in ACS patients, when all inflammatory mediators are taken into account in a prospective analysis of risk, markers reflecting anti-inflammatory mechanisms are better prognostic markers.

Abstract
INTRODUCTION The balance between pro-inflammatory and anti-inflammatory molecules is likely to modulate the processes that lead to atherogenesis and rapid coronary artery disease progression. We sought to compare the positive predictive values of serum soluble CD40 ligand (sCD40L)/interleukin-10 (IL-10) ratio, versus individual sCD40L, and IL-10 measurements regarding in-hospital events in patients admitted into the hospital with ST-segment elevation myocardial infarction (STEMI). METHODS We recruited 96 patients with STEMI. sCD40L and IL-10 were measured at hospital admission in every patient. The composite of in-hospital death and heart failure represented the study end-point. Heart failure was defined as Killip class>1. Multivariable logistic regression analysis was performed to identify independent variables related to in-hospital events. RESULTS Thirty two patients (33%) achieved the study end-point and 64 (67%) had no adverse events during hospital admission. IL-10 levels (pg/ml) were lower (28.2+/-9.8 versus 33.24+/-11.3, p=0.03) and sCD40L levels (pg/ml) higher (156.8+/-54.2 versus 135.4+/-38.70, p=0.02) in patients with events compared to those without events. Significantly higher odd ratios were found for sCD40L/IL-10 ratio (OR=2.10, 95% CI: 1.90 to 2.80, p=0.01) compared to individual sCD40L (OR=1.40, 95% CI: 0.90 to 2.20, p=0.08) and IL-10 (OR=0.70, 95% CI: 0.50 to 0.93, p=0.02) measurements. CONCLUSION Our study showed that serum ratio of sCD40L/IL-10 is a better independent predictor of in-hospital adverse events than individual sCD40L and IL-10 measurements in patients with STEMI.

Abstract
BACKGROUND The pro-inflammatory cytokine IL-18 has been suggested to play a role in atherogenesis and atheromatous plaque rupture leading to the acute coronary syndrome (ACS). Conversely, the anti-inflammatory cytokine IL-10 seems to have an atheroprotective role. Patients with unstable coronary artery disease show an imbalance between serum levels of pro- and anti-inflammatory cytokines, and studies have shown that IL-18/IL-10 ratio is an independent predictor of adverse in-hospital events in patients with ACS. We assessed the long-term prognostic significance of admission interleukin-18 (IL-18)/interleukin-10 (IL-10) ratio for recurrent coronary events during a 1-year follow-up in patients presenting with an ACS. METHODS We assessed independent predictors of the combined end-point using multiple logistic regression analysis, in 186 patients (138 men, 65+/-12 years) with ACS (75 STEMI, 65 NSTEMI and 46 unstable angina). The composite of cardiac death and re-hospitalization with non-fatal myocardial infarction, or unstable angina, was the pre-specified study end-point. Serum IL-10 and IL-18 levels were measured at study entry using commercially available ELISAs. RESULTS During the 1-year follow-up, 48 (26%) patients had recurrent cardiac events and 138 (74%) were event-free. IL-18/IL-10 ratio predicted the occurrence of adverse cardiac events (OR 1.91, 95% CI 1.37-2.65, p<0.001), and was found to be an independent predictor among other established biochemical and clinical risk markers (OR 2.31, 95% CI 1.55-3.42, p<0.001). CONCLUSIONS Serum IL-18/IL-10 ratio is an independent predictor of recurrent coronary events during long-term follow-up in patients presenting with ACS. Our study further supports the hypothesis that the balance between pro-inflammatory and anti-inflammatory cytokines may be an important determinant of patient outcome, suggesting a pathogenic role in plaque progression and instability.

Abstract
Acute coronary syndromes represent a complex phenotype involving the interplay of many elements. The risk of developing an acute coronary syndrome and related complications has been defined by variables such as age, diabetes, smoking history, serum creatine phosphokinase, or electrocardiographic findings. However, in the past 5 years the wide-scale acceptance of a protein--troponin--has changed the diagnostic profile. With advances in molecular medicine, this protein is a segue to a panel of molecular assays that will improve screening and tailored intervention. We expound upon some of these factors and the potential they may carry in changing clinical medicine.

Abstract
OBJECTIVE We performed a prospective case-cohort study in initially healthy, middle-aged men and women from the MONICA/KORA Augsburg studies conducted between 1984 and 2002 to assess the role of IL-18 in comparison with IL-6 and CRP in the prediction of incident coronary heart disease (CHD). METHODS AND RESULTS Concentrations of IL-18 were measured in 382 case subjects with incident CHD and 1980 noncases. Mean follow-up was 11 years. Baseline concentrations of IL-18 were slightly higher in cases than in noncases (172.4 [1.0] versus 161.3 [1.0] pg/mL, respectively; P=0.114), but were clearly elevated for C-reactive protein (CRP) and IL-6 in cases compared with noncases. In multivariable analyses, accounting for classical cardiovascular risk factors and inflammatory markers, no statistically significant association was seen between increased concentrations of IL-18 and incident CHD both in men (hazard ratio [HR] and 95% confidence intervals [CIs] comparing extreme tertiles, 1.20; 95% CI, 0.85 to 1.69), and in women (HR, 1.25; 95% CI, 0.67 to 2.34). However, in this population increased concentrations of CRP and IL-6 were found to be independent predictors of future CHD events, even after multivariable adjustment. CONCLUSIONS Elevated concentrations of CRP and IL-6, but not IL-18, were independently associated with risk of CHD in subjects from an area with moderate absolute risk.

Abstract
OBJECTIVE To investigate the relation between serum high sensitivity (hs) C reactive protein (CRP), proinflammatory cytokine concentrations, proinflammatory to anti-inflammatory cytokine ratios and long-term prognosis in patients with non-ST elevation acute coronary syndrome (NSTEACS). DESIGN Prospective follow-up study for the first six months and then for the first year after admission to hospital. SETTING Tertiary referral centre. PATIENTS 80 patients (60 men, 20 women, mean age 60 (SD 10) years) with NSTEACS and moderate to high TIMI (Thrombolysis In Myocardial Infarction) risk scores. INTERVENTIONS Blood samples from patients with NSTEACS were obtained at the time of admission. Serum concentrations of hs-CRP, (hs) pro-inflammatory (interleukin (IL) -1beta, IL-6, tumour necrosis factor alpha) and (hs) anti-inflammatory (IL-10) cytokines were analysed and proinflammatory to anti-inflammatory cytokine ratios were calculated by dividing proinflammatory cytokine concentrations by anti-inflammatory cytokine IL-10. MAIN OUTCOME MEASURE The primary end point of the study was new coronary events (NCE) defined as the combination of cardiac death, non-fatal myocardial infarction and recurrent rest angina that required hospitalisation within 12 months of follow up. RESULTS During the one-year follow-up period, 23 patients (29%) met the NCE criteria. Concentrations of hs-CRP, IL-1beta and IL-6 and ratios of IL-1beta:IL-10 and IL-6:IL-10 were significantly higher in patients with NCE than in patients without NCE. In the logistic regression analysis, IL-6:IL-10 ratio was the most important predictor for NCE (p = 0.006) with an odds ratio of 2.24 (95% CI 1.26 to 3.97). CONCLUSIONS Cytokine concentrations and proinflammatory to anti-inflammatory cytokine ratios may be useful markers for predicting vascular risk in patients with NSTEACS.
